And linux too!
But maybe I should really hate programmers: ere is the story:
I needed to edit a text file of 180MB so I started an editor on my windows laptop: after about half an hour I was greeted with a message stating that I had not enough virtual memory.
So I had a notebook with 512MB plus 1024MB of swap and this was not enough to view the file.
Which incredible memory allocation perversion drives the memory needed to load a text file to more than 7 times the file size?

So I thought: I'm a smart ass, I'll do it on linux.

And transfered the file on my mandrake 10.1 (updated to 10.2) and wrote "vi file" and I was greeted with a great news: vi is missing a required library from perl.
Why in the hell does vi in linux require perl? And how the f**king mandrake update screwed even the most basic tool?
Keep it simple is no longer a good programming principle after the Vic20 3.5KB of memory was increased to multy MB?
BTW somewhere in the machine there was the damned library.

Before going into killing rampage I decided to connect in vpn to the work and use a remote machine: on a sun vi almost worked with this file.
Almost because there was not enough space on /tmp and I had no way to increase this space.

It was really a bad day.


Hmm - yeh, I know the feeling! Not surprised that your windows box didn't cut the mustard, but I'm shocked that your upgrade of Mandrake disabled vi. An often-overlooked fact is that if your editing operations are reasonably simple (something like a search and replace for example), you can ask sed to do it. It means being comfortable with regex's though, but great stuff if you're happy to just type a single command and then rest assured it will be done in seconds.
I picked up an old AlphaStation 200 4/233 recently and decided to try and install Tru64 5.0 on it - the first time I've had my hands on either AXP hardware, or the operating system.
In goes the CD-ROM and all goes well after I quickly learn how to pass commands to the boot prom based monitor. Everything starts well, up comes a managed display with twm and an installation script written in tcl/tk (it's quite obvious when you see it). All is straight-forward and logical given it's essentially just a flavour of Unix - timezones/locales, networking, etc. Then I get to set up a user account, so I create one for me of course.
I complete installation, reboot and try to log in and it says that I can't because it says "Too many users logged in already", ahhh, sh!t, this doesn't look good - I've just rebooted and there are too many bloody users logged in already - they must have been quick.
A root login turns out to be acceptable to the system, so I suspect some tight-arsed license restriction problem is coming up - sure enough, a quick "google groups" tells me that I need a special "PAT" to type in, and that I can get a hobbyists license for US $99. I'm not so sure - the license includes media, which is alright and I think it might also include a development option - which would be pretty good if that were the case, but I can't afford to put my hands on US $99 plus shipping at the moment.
I'll be damned if I put anything else on it (not that I'm against Linux, FreeBSD or the other ported environments at all - they have their place on PCs, not on hardware that has a native OS, or at least that's my take on it).
Anyone had any experience with Tru64?
Um, yeh - I haven't (yet) purchased a license for a platform that is retired, but I'd presume that paying US$ 99 would allow me an installation with more than one login (which is what is already available without any license at all).
Things would be a bit clearer if it at least asked me for the necessary key or PAT or a flexlm server or whatever at installation time - which it didn't.
Maybe OpenVMS would be a good laugh instead - I haven't used VMS since 1984, then it was on a VAX 11/780, .... wow, I'm turning into an old fart.
Beer: Boddingtons of Manchester, Robinsons of Stockport
Lager: DAB, Hansa, Grolsch, Amstel, Warsteiner, Tuborg, Dortmunder Union, ... or anything brewed under the Reinheitsgebot (apologies to Deutscher folks if the spelling isn't correct). Anything except the local Australian crap which is brewed with sugar and topped up with preservatives and artificial colourings - disgraceful!
Wine: MacLaren Vale reds (red wines are one thing that are created properly locally, in our warm dry climate)
Spirits: Jamesons (Irish as noted by Dubthach I think), Dalwhinnie (Scotch - superb) both of these should of course be consumed straight from the glass (or bottle :wink: )

Kampai! Prost! Yum Sing! Naz'drovya! Skol! Cheers! ....
@psergiu : If you haven't got a graphics adapter at all and want one, then I've got one that might suit. I can't remember the model number, but it was a reasonably standard MCA card out of my old 7012 model 36T - it'll only support 8-bit colour depth, but better than nothing.
If you're interested, let me know - you can have it for the cost of trans-Pacific postage. I'll email you the specs first (the card is in the office and I'm at home at the moment).
Btw on my machine (50 MHz PPC) AIX 5.1 was too slow to use interactively (even with 256 MB RAM), so I dropped back to 4.1.5 which fine - so don't be too disappointed with performance.
2 Jan-Jaap: working perfectly for me on my Linux box (Fedora Core 2) - well done champ, thanks very much indeed!
Any neko-soccer fans out there??

Sorry mate - NO, I used to be into the game pretty seriously, but finally I just couldn't take any more of the diving. All the rolling around on the ground, faces contorted in cross-eyed agony because "some guy pushed me over!" just gave me the shits - especially when they're up and about only seconds after a friggin' stretcher appears on the scene. Some teams are notoriously bad at this particular practice - but I'm too much of a gentleman to start pointing them out. As much as I think the game itself has merit as a team sport, I just couldn't point to it and say to my son "there you go, that's what the best in the world do in this particular code of football". It's just plain embarrasing.
In the end it was Rugby Union that struck me as being distinctly gladatorial and superbly spectacular as a real physical contest - no room for "shirt pulling", mock injury and other such wankery in Union.
I hope some of you are able to tune into a first class example of exactly what I mean this weekend (Sunday 11th) when Australia play England in Rugby in Sydney - a rematch of the 2003 Rugby World Cup Final which England won by a field goal (goddamn it) in extra time. I guarantee you, you won't see anything like what you'll be sickened by in some (not all) of the soccer matches that are coming up. Australia will put at least 40 points past England, who will gallantly go down with all guns blazing - great stuff!
I'm a jaded ol' fart and also a lecturer at the University of Technology, Sydney. In the good old days, I used to lecture courses in real-time operating systems, microprocessors, programming languages, etc., but these days I'm obliged to wade though huge amounts of paperwork (applications for exemptions, changes of course/major, appeals against assessment grades, etc.) and it's bloody soul-destroying.
In my office I have my Octane, Iris Indigo, Indigo2 and O2 (all bought using my own money) and it pisses me off that I don't get the time to tool around with them any more.
Maybe when I've finished marking these exams ....

Inserted CD labaled "LCD4_1061_01 Volume1"
Connected an 19200 8n1 serial console to S1
Moved the key to service mode & power on
Lo & Behold, the system boots directly into diagnostics which i run and everything seems OK except the simms from the I2 which are not detected.
Moving the key to Normal, the system boots from the HDD.
I have 5 CDs which are suposed to be the AIX 5.1 Kit:

CD Volume label (marker scribbles on the cd):

LCD4_1061_05_VOLUME1 (1451 1)
LCD4_1061_05_VOLUME2 (1521 2)
LCD4_1061_05_VOLUME3 (1526 3)
LCD4_1061_05_VOLUME4 (1533 4)
LCD4_1061_05_VOLUME5 (1538 5)

- Are those the right cds ?

Hmm - I don't know about that, the ones that I've had in the past haven't had labels like that on them. I've not actually got mine at hand at the moment, but the next time I'm in the office I'll check them for you.
- Which one is the install cd ? (CD2 does not seem bootable at all)
- How can i start the installation ? (i know it won't work with 16Mb of ram, i just want to see it trying to boot)

Well the first thing you need to ensure is that you've got a CD-ROM drive that the compatible. I spent months getting one that booted with 512 Byte sectors that would work. Even some IBM drives, that had jumper settings on them that allowed me to configure 512 Byte sectors, would not work. The symtom was always that the machine would boot to the maintenance menu, instead of the boot/install menu. In the end, just through trial and error, I discovered an old Plextor drive that was acceptable - it took me months, and it was very much a pain in the arse.
- Any SIMM reccomendations ?

I was lucky in this respect, in that I was able to get one of the special riser cards that was compatible with my old machine when I got it. I'm really not at all sure which types of SIMMs they take. I'll have a look amoungst the references I've got here though and let you know if I find anything. The guy I got it from was based in Deutschland, and I'll give you his online-address too if you wish.
- Any 7011 Manual ? (on the IBM's site the history starts with 7012)

Can't hep you there, I've only got a 7012 machine.

OK mate, I've got some more information for you:
- The CDs that came with my machine when I got it say "5765-393 AIX TM 4.1.5 for Server for G5 Processors". There are two discs that make up the distribution. I think I mentioned before that I put 5.1 on it and it was so slow that it was inoperable.
- As for the memory, the SIMMs have a sticker on them that says "32G7699A 68X6357 98A 3 227" and the actual on-chip designation says "0169250 IBM 9898 JAPAN 9303 2396". These ones are 8 Mbytes in size.
- When it comes to CD-ROM drives, it's a real lottery as I said. Here's a link that might help though: ... 00051.html
- Just found this too, when I was looking for something else ( ), I've not dealt with them before, but if you need memory you might be able to score here.

Sorry that I haven't yet got a shipping price for you on that framebuffer card, but I've been tied up marking examination papers for the past several days. I'll get on to it soon.

Yes, well it may well be some sort of multi-platform support thing - but I can tell you for a fact that this very distribution installs on an RS/6000 Model 36T (which is a 50MHz PPC machine with MCA). I've installed it twice from CD-ROM, no problems (with an acceptable CD-ROM drive as per above).
It constantly segfaults on an Octane with 6.5.21, of that I can assure you :(

I have a Octane2 V10 R12k/400MHz Irix 6.5.22.
Must be something with different versions of freeware and nekoware whichever gets loaded first and is first in the searchpath....

On this latter point, good try but I think not - it might be heretical to admit it here, but I have no nekoware installed on my Octane at all and I get a segfault every time I attempt to start partiview.

Yeh? - just how much better in terms of fps would "quite better" likely to be?
In order for someone to volunteer the many, many hours that would be needed, it would be necessary to have some sort of estimate. Based on heuristics and deBugs numbers, I don't think it would be worth it at all - with un-SGI-optimised code producing an average of 9 fps on a 600MHz R14000 with V12, we'd be needing something more like "outstanding miracles" rather than "quite better".
