Comment All about the IO units (Score 1) 558

Who cares what's in the computer case? Well, it should work of course. ECC RAM, certainly. But the important parts are the keyboard, trackball and screen. I have an old Dell keyboard with Alps switches. (I don't remember what kind exactly. Something tactile.) I have the worlds best trackball, the Logitech TrackMan Marble FX. And I have a 1920x1200 IPS screen with fairly accurate colours. (Plus an extra 1600x1200 IPS screen with not so accurate colours that is usually turned off.)

(But to answer the question a bit: FX8350/16GB ECC/some SSD/cheapest gfx card in the store.)

Comment Re:google tranlate is quite good... (Score 1) 132

Google translate is possibly hillarious, but good? Let's try something I saw recently:

The letters are your own business.

google translate to Swedish:

Bokstäverna är ditt eget företag.

or German if you prefer:

Die Buchstaben sind Ihr eigenes Geschäft

and then I'll translate it back to English for you using my brain (the Swedish and German mean the same thing, I'm fairly sure, though I don't speak German):

The ABCs are your own corporation.

That's not good, that's incomprehensible. You have to know that these words are the same in English to have a chance of understanding it.

Comment I made my own (Score 1) 259

I made my own image tagging software, which is likely to be supported (for me, by me) as long as I care. It's probably not the right choice for most people. Anyone who wants to use mine is free to do so, but it's not well packaged. Undoubtedly missing features some people consider mandatory. It also makes some unconventional choices.

If anyone wants to try it I will answer email about it, and we can arrange to meet on IRC. There are several mode repos on the same github account (that are part of the same system).

Basic ideas:

Client/server model. Server in C, client in python.

Everything you do it kept forever. The only persistant metadata storage is a log of everything you've done.

Image files are never ever touched. They are identified by their hash. Anything messing with them will break this.

There's a fuse filesystem for searches, which you can use with whatever viewer you like. There's also a (crappy) web interface.

You can import raw files and see jpegs in the fuse fs/web client. (The embedded jpeg found in nearly all raw files.)

Comment ZFS (Score 1) 153

In the grand internet tradition of answering a loosely related question which is no use at all to the asker, I will say that the "smart kids" might use something like ZFS, which almost handles this for you. (Take snapshots, save delta streams on your USB stick. Requires the backup to be a ZFS copy, not just the same files.)

Useless right now at least. But I've been pretty happy with switching my storage to ZFS, even if the Linux version sucks. (I mostly don't use the Linux version.) I'd recommend it to anyone who doesn't mind a bit of transitional pain.

Comment Re:The Internet is based on C (Score 2) 201

Keyword: cognitive load. Case in point: hilariously excrutiating code example in linux man page of snprintf. If you need to jump through all these burning hoops to do something this mundane, imagine how much more your proficient C coder could achieve in a more sensible laguage with the same amount of effort.

A sensible C coder might use vasprintf instead of the example in that manpage. The fact that all the standard library functions aren't great for all (or sometimes any) use cases is hardly unique to C.

Comment No browsing (Score 1) 429

My main computer doesn't run a browser. (It does run a virtual machine with a browser.)

I think this and not being reachable from the public internet is all the protection it needs. (It's also running Ubuntu, but I don't think that makes any noticable difference compared to some other modern choice.)

Comment Re:What is wrong with just plain dump? (Score 2, Informative) 300

I'm pretty sure the Linux version of dump doesn't do any snapshoting. The FreeBSD version can do it because the FS supports snapshots, but ext3 does not. (Maybe it will do snapshots automatically if you have a setup that will support them, but the original problem is that this is not the case.)

Comment Re:ECC on a home system? (Score 1) 333

Yes, I am saying that. There are options for:
DRAM ECC enable
DRAM MCE enable
Chip-Kill mode enable
DRAM ECC Redirection
DRAM background scrubber
L2 cache background scrubber
DCache backdround scrubber

The full specs of my board are GA-MA770-UD3 rev 2.0 with BIOS version "FA", Kingston valueram ECC memory, Athlon X2 BE-2400 CPU. So tech support could be right for the board you asked about, though probably not.

Comment Re:ECC on a home system? (Score 1) 333

While it's certainly true that most consumer boards don't have BIOS support for ECC, my Gigabyte GA-MA-770-UD3 does, so gigabyte probably doesn't lie when they claim support on other boards. (But these options are not shown if you don't actually have ECC-memory, so you could easily fool yourself when you check for it.)

Also my slightly older ABit AN-M2HD supports ECC. Both boards were bought with ECC in mind, it's not all that common. But it's certainly possible to get.

Comment Re:No Battery? (Score 2, Insightful) 195

I suspect they have a capacitor large enough to finish committing their buffers. At least they seem to see little performance degradation with write barriers, and do retain all the files they should when I pull the power while writing. (I didn't do a proper test, but it seems to work correctly, assuming your OS does.)

(And for the record, any OS that still thinks anything the HD acks is written is living in a dream world, it hasn't been true for 15 years on consumer disks.)
