ReiserFS stores file metadata ("stat items"), directory entries ("directory items"), inode block lists ("indirect items") and tails of files ("direct items") in a single, combined B+ tree keyed by a universal object id. Disk blocks allocated to nodes of the tree are "formatted internal blocks". Blocks for leaf nodes (in which items are packed end-to-end) are "formatted leaf blocks". All other blocks are "unformatted blocks" containing file contents. Directory items with too many entries or indirect items which are too long to fit into a node spill over into the right leaf neighbour. Block allocation is tracked by free space bitmaps in fixed locations.
By contrast, ext2 and other Berkeley FFS-like filesystems simply use a fixed formula for computing inode locations, hence limiting the number of files they may contain. Most such filesystems also store directories as simple lists of entries, which makes directory lookups and updates linear-time operations and degrades performance on very large directories. The single B+ tree design in ReiserFS was intended to avoid both of these problems.

I'd probably say reiser is ok for a dev workstation for these reasons, but yea, if you ran into those problems, avoid it. I had amazing performance with it being used to torrent tons of stuff while doing lots of huge compile jobs.

I'm happy with XFS! Its data-loss-on-crash issues are reportedly less common and less destructive than Reiser's.

Paul Eater (eater), Tuesday, 28 March 2006 18:09 (eighteen years ago) link

Yea, I think I'd probably use XFS now. I remember being scared by how much freaking code comprised it!

Houdini Gordonii (ex machina), Tuesday, 28 March 2006 18:12 (eighteen years ago) link

Yes, I know how to find Wikipedia, thanks. Responding to the highlighted bits:

By contrast, ext2 and other Berkeley FFS-like filesystems simply use a fixed formula for computing inode locations, hence limiting the number of files they may contain.

A default ext3 filesystem, off the top of my head, has 1 inode for every 4k of disk space. Hence, if your average file size is under 4k then you'll run out of inodes before data blocks. I don't think there are many situations where that is likely to apply.

Most such filesystems also store directories as simple lists of entries, which makes directory lookups and updates linear-time operations and degrades performance on very large directories.

Ext3 doesn't have to, though - it can store directory contents either as a list or a b-tree.

Filesystem comparisons are hard to do, normally, because it's rare to switch between filesystems on one machine.

Aha, you are right about the directory list entries.

Jon is there any acceptable reason another human being should use a computer in a fashion that is not identical to the way you use a computer?

meanwhile, back in the real world: anyone else having problems with gmail notifier? mine's fucked.

the gmail+growl site suggests some kind of weird shit is going down. it's been knackered for me since 9.30am BST today.

ymail notifier breaks for me like every 2nd day. (no need for gmail notifier since i just pipe gmail straight to Mail.app) still i keep it around, dunno why.

Sterling Clover (s_clover), Tuesday, 28 March 2006 19:42 (eighteen years ago) link

I don't understand why peoplee think webmail is such a hot idea. It is good when you're traveling but nothing beats organizing your own shit in folders with good drag and drop etc. I keep my folders for work imap synced. Since I use a laptop, it is handy to have offline access to mail.

Houdini Gordonii (ex machina), Tuesday, 28 March 2006 19:47 (eighteen years ago) link

y no smartfolders, jon?

Tracer Hand (tracerhand), Tuesday, 28 March 2006 19:59 (eighteen years ago) link

I use smartfolders as views for stuff but I like my "Inbox" to only have non mailing list traffic as the unread count in the dock icon corresponds to the number unread in the inbox. Also, with colors I can see where stuff is from in any of my smartfolders ("Today", "This Week", etc). These rules also move each mailing list into its own folder.

Finally a PEEVE with Apple Mail -- Why doesn't each folder remember which columns you had turned on in it rather than the setup now where the columns are GLOBAL.

Houdini Gordonii (ex machina), Tuesday, 28 March 2006 20:02 (eighteen years ago) link

that's cool jon. i like your style.

by the way, I LOVE TEKSERVE. hardware problem requiring new top casing & trackpad = fixed overnight.

Tracer Hand (tracerhand), Tuesday, 28 March 2006 21:56 (eighteen years ago) link

I don't understand why peoplee think webmail is such a hot idea.

Neither did I, until I started using Gmail. Conversations and fast-searching are such great additions to mail that I'm never going back. Spotlight can search -- slowly -- at home, but what about when I'm not? Mail.app and other clients have pissy little stabs at "threading", but they're all shit compared to conversations. And are useless away from home.

If only Gmail had IMAP, it would be the best of both worlds.

stet (stet), Tuesday, 28 March 2006 22:30 (eighteen years ago) link

all this stuff

RJG (RJG), Tuesday, 28 March 2006 22:31 (eighteen years ago) link

If gmail had IMAP, I'd probably use it instead of fastmail, as it is I use it as an extra thang and at home use Mail.app (which searches very fast, in my experience). And I don't really like the conversation thing in gmail. I'm a bit old school about email presentation.

Alba (Alba), Tuesday, 28 March 2006 22:42 (eighteen years ago) link

I have my first ever apple...thing, since my v generous birthday

I almost got hit by a car, today! listening to my ipod. luckily it was the guy next to me and I only got hit by him phew

RJG (RJG), Tuesday, 28 March 2006 22:50 (eighteen years ago) link

i use a gmail address but like i said check it generally via Mail.app. I find it handy to still be able to access it as straight gmail while I'm at work. I figure too its more perm than any provider type acct and more portable and etc.

yahoo makes you pay for pop so i don't do that and i'm generally trying to wean myself off it but it still gets used for a couple older mailinglists.

Sterling Clover (s_clover), Wednesday, 29 March 2006 03:19 (eighteen years ago) link

I don't know why I'm here. I don't hate Apple.

me neither. but i do get very frustrated with them sometimes.

grimly fiendish (grimlord), Wednesday, 29 March 2006 07:39 (eighteen years ago) link

I can't believe that problems like that with reiser exist

Paul Reiser?

Markelby (Mark C), Wednesday, 29 March 2006 09:03 (eighteen years ago) link

No, Hans.

Forest Pines (ForestPines), Wednesday, 29 March 2006 09:59 (eighteen years ago) link

whoever was the dumbshit that said applecare was $60 is a fuck off. It's $250 dollars for an iBook, which is the cheapest laptop and $100 for a new iPod with video .Dip shit. besides, macs are great compters and apple has great support.

WEEBEL, Monday, 3 April 2006 02:01 (eighteen years ago) link

I hate macs. So there.

Gary Ganu, Thursday, 6 April 2006 19:16 (eighteen years ago) link

I hate macintosh... They always @#*)(*@$& CRASH!!!!!!!!!!!!!!!! Today as I work at the library, I have experienced several crashes and had to restart twice. The main directorys cannot be found and everything is having unexpected errrrrrrrrrrrrors!!!!!! I used to have a mac at home which does this exactly same f@#(@&#( thing!. MACs suck shit. PCs are the best thing ever as they beat Macintrash by 110000000000000000000000000:1

OMFG THOSE OF WHO USE MACS WILLINGLY ARE ASSHOLES. I AM FORCED TO SE MACS AT SCHOOL AND EVERT 15 MINUTES THE GODDAMN THING CRASHES, OR OVERHEATS OR FREEZES OR ENCOUNTERS TERMINAL SYSTEM FAILURE, OMFG GROW A GODDAMN BRAIN ASSHOLES I OPE AL MACS BLOW THE FUCK UPA ND NEVER WORK AGAIN

Wilkie, Tuesday, 11 April 2006 01:35 (eighteen years ago) link

MACs really suck... they always crash and are the hardets thing to use in history.

Truman Heeler, Tuesday, 11 April 2006 01:36 (eighteen years ago) link

macs always blow up, killing their operators. so hard to live with max.

Dan Selzer (Dan Selzer), Tuesday, 11 April 2006 02:49 (eighteen years ago) link

Well, I'm posting on a mac right now and it's running just fine. I think macs are beautifully constructed pieces of machinery that....

**okay - it's not looking - my mac has tied me up and is forcing me to do it's evil bidding - send help right away. I... oh no... no, I wasn't doing anyth... no please... NNNNOOOOOOOO

THE EVIL GENIUS BAR GUY SENT MY COMPUTER IN. HE SAID IT WAS JUST TO REPLACE THE DC INBOARD AND THAT IT WOULDN'T EFFECT MY FILES. MY COMPUTER CAME BACK. IT HAS A NEW HARD DRIVE. I REALLY REALLY REALLY HATE APPLE.

(Yes, I'm an idiot for not backing up my files but I bought the external hard drive and couldn't get the computer running long enough to do so.)

Apple Tech is going to call me back. I hope they can make some amends.

Mary (Mary), Wednesday, 19 April 2006 17:26 (seventeen years ago) link

oh no!!!

Tracey Hand (tracerhand), Wednesday, 19 April 2006 17:39 (seventeen years ago) link

OH WOW! I had to send my computer in but they actually called me before doing so

JW (ex machina), Wednesday, 19 April 2006 17:43 (seventeen years ago) link

yeah they basically do this with everyone, just to let you know who's boss. I'm amazed they actually called you JW. They must know you're an obnoxious fanboy evangelist.

TOMBOT (TOMBOT), Wednesday, 19 April 2006 17:45 (seventeen years ago) link

I did mine through the Apple Tech's at my old uni, who don't work for Apple or the uni.

JW (ex machina), Wednesday, 19 April 2006 17:46 (seventeen years ago) link

Oh, you mean non-Geniuses.

TOMBOT (TOMBOT), Wednesday, 19 April 2006 17:56 (seventeen years ago) link

Fuck Apple Customer Support

TOMBOT (TOMBOT), Wednesday, 19 April 2006 17:57 (seventeen years ago) link

hugz Mary, I know I joked on the DC thread but that really does suck. If they can't locate your missing parts you should go ahead and request they give you a brand new computer since this one is just going to break again anyway!! I mean fuck.

Allyzay Rofflesbot (allyzay), Wednesday, 19 April 2006 18:40 (seventeen years ago) link

I know, this one went from brand new computer to need new logic board in the space of 2 years, beating my previous Mac's logic board, which wanted a replacement after 4 years. What do I do to these poor logic boards?

I still have Apple care for another year so hopefully the new drive and board will last that long.

My moms told me I should take it to this little Mac stand on Route 1 and I checked they did accept Apple care and they are certified technicians and all that, but for some reason I thought it would be easier to take it in to the store. Next outage I'm gonna see what the mom and pop can do.

Thanks everyone for the advice and support. It's not as traumatic this time around, as it was the last time my computer broke. (It also helps that my mom has an identical computer in the basement for moments like this.)

The only thing I really got screwed on was some pictures I only had on the computer.

I think from now on I'm going back to analog.

Mary (Mary), Wednesday, 19 April 2006 19:22 (seventeen years ago) link

you're going back to analog! I smashed my laptop into submission with my head and still regret that I cannot also do my job using only pen & paper! As far as I'm concerned I'll take a blackberry and a Nintendo DS and that's all I want. No more of this hullaballoo over infotech for me.

TOMBOT (TOMBOT), Wednesday, 19 April 2006 19:24 (seventeen years ago) link

Ed (dali), Wednesday, 19 April 2006 19:27 (seventeen years ago) link

Ed, how in the hell have you kept your black g3 working? Have you replaced every single part inside of it? I'm now two hard drives removed from that computer.

Mary (Mary), Wednesday, 19 April 2006 19:56 (seventeen years ago) link

My Black G3 died after 5 years of use. They seem to have been the best built PowerBooks ever. Suzy has just inherited a first generation G3 powerbook (SCSI, no USB or Firewire) which still seems to be going strong, must be 7 years old by now, probably more.

My theory with laptops is that you can't expect the hard drives to last more than two years and should expect them to go at any moment. A hard disk is a fundamentally stupid thing to put in something that moves around all the time. Optical drives will go quickly as well and in my opinion should be left out of portables. DC boards appear to be another flakey item (that's what finally went on my G3), I don't know what kills them.

I guess as much RAM as possible can help to extend hard disk life. Making sure your laptop always has good airflow must do something to help keep everything going.

I can't wait for solid state disks to be cheap enough and reliable enough to be regular fixtures in laptops.

Ed (dali), Wednesday, 19 April 2006 20:06 (seventeen years ago) link

I have my laptop on my desk now intead of my bed. And how much RAM do you recommend, Ed? I had 512, but they stole 256.

Do you have any theories about logic boards?

My mom has the first model of the white powerbook--and it's still fine after three years, but she uses it a lot less than I do.

Mary (Mary), Wednesday, 19 April 2006 20:12 (seventeen years ago) link

As much RAM as you can get in there, the maximum, I think 768MB in your case.

I think what kills logic boards is the fact that as the laptop gets hanles, especially if you pick it up by one corner, it places a lot of stress on the board and on the solder that holds components to it. Eventually something cracks or becomes disconnected. I gues to reduce this, always pick up the laptop by both sides and always use on a firm surface, says the person using his work laptop balanced on his knee, lifted there by once corner.

I guess you shouldn't expect a laptop to last like a desktop. Plan on replacing them every couple of years or so.

Ed (dali), Wednesday, 19 April 2006 20:23 (seventeen years ago) link

my 1997-vintage powerbook 5300 is still going strong [1] - and it once had a ceiling fall in on it. and this was meant to be the duddest PB ever made!

[1] unless stet, who is currently looking after it, has broken it. or one of our mutual friends has been sick on it. mate?

grimly fiendish (grimlord), Wednesday, 19 April 2006 20:24 (seventeen years ago) link

my 98 G3 is still fine on os9

gabbneb (gabbneb), Wednesday, 19 April 2006 20:25 (seventeen years ago) link

Ed, that is good news for people with metal powerbooks and 12" laptops :D

JW (ex machina), Wednesday, 19 April 2006 20:26 (seventeen years ago) link

no wait, my G3 was replaced sometime 99ish, wasn't it? Ed OTM about treating it right. i put it on a table and move it only when necessary.
