I read it up until the point that my browser "couldn't find the server". Couldn't really see the comment. BUT I prefer to use the addage: To increase a servers speed- add more RAM, to increase it further add EVEN MORE RAM. Same for desktop, ESPECIALLY since desktops tend to use IDE rather than SCSI(which is still not as fast as RAM). 128 MB (or 256 to be sure) should be fine, unless you use intensive apps such as 3D rendering and GIMP on big piccies. With the advent of large (32MB+) graphics cards, even 3D games don't really dent your RAM that much. I'm not sure if the kernel actually needs a swap partition to be present, but in general losing 128 MB on a HD isn't exactly a great loss (especially as I couldn't find a first-hand IDE drive with less than 20GB), and £50 for 512MB isn't either (of course, that's just excessive, I was just trying to future-proof as much as poss). My bets are: loadsa RAM, small swap. I think the 2xRAM thing was also partly due to RAM being expensive once-upon-a-time.

Swap space
by John Seago 29 Nov '01

29 Nov '01

I would like to thank every body who has sent me advice on this matter, I have decided to go with x2 > x4 swap space, (space being of no consequence as I have a total disk space of more than 50 gig). As predicted, this seems to have sparked a technical discussion which I don't understand, I'm glad I didn't ask to have it explained to me! Once again thank you everyone for your advice. John seago

I have 512MB RAM (& kernel 2.4.3), and only 133 MB swap space (to use during the install), and find no performance problem in any way. In fact the opposite! There is simply no reason for me to use 1GB of swapspace! Besides which RAM is *much* faster than swap, easier to upgrade, and just stupidly cheap. I only spent £40 on 512MB (that's probably expensive now), & don't expect to upgrade anytime soon....... I have noticed one thing, though: about 2 mins after my box boots up and I'm into my WM (WindowMaker at the mo'), it pages (oops I mean writes-to-disk/swap?) like crazy for about 5 seconds, then NEVER does it again (until I reboot for whatever reason). This is different to Windoze 2K server on the same machine, for example, which pages like crazy just for the hell of it, inefficient little beasty that it is!

Re: [Alug] Filtering spam in Linux

> My main email address has been activate for about 3 years and thus gets a > lot of spam. Are there known methods inside Fetchmail or procmail to filter > out 'spam' into a separate folder for later viewing? I filter everything that mentions me in the address lines, or looks like a mailing list, into their own folders. Everything else goes in "uncaught" and I read that folder a *lot* less often. I'm using slocal/.maildelivery, so the basic idea is: # .maildelivery file for nmh's slocal # Blank lines and lines beginning with a '#' are ignored # FIELD PATTERN ACTION RESULT STRING # Trap fscking badtrans From <_ pipe R "/home/markj/usr/bin/badtranswarn" # Filter some mailing lists To ezine@author folder ? lists-moderated # All our lug-related lists into one folder List-Id lug folder ? lists-lug Sender ebi.ac.uk folder ? lists-lug # LUG box still uses pre-list-id majordomo Sender lug.org.uk folder ? lists-lug # Try to catch all other lists in the bucket List-Post . folder ? lists Delivered-To "mailing list" folder ? lists List-Id . folder ? lists X-Mailing-List . folder ? lists Sender owner- folder ? lists # Things really addressed to me To markj(a)cloaked.freeserve.co.uk folder ? inbox Cc markj(a)cloaked.freeserve.co.uk folder ? inbox # Put anything not matched yet into uncaught default - folder ? uncaught > If not, do people on the list use services to eliminate the spam?

SNMP Load averages...
by Simon Parkes 28 Nov '01

28 Nov '01

Hi, I'm hoping someone can help lift the mist from my eyes... doing an snmpwalk of my PC on .1.3.6.1.4.1.2010.10.1.3 gives me 3 results (as expected), these are the load averages of 1, 5 and 15 mins.. Can someone tell me what might be a high value ? My 1 min load average is 3.66 most of the time.... 3.66 out of what? 100, is this a percentage? Any ideas anyone... Simon

I think the whole taxation system needs a good tidy up. However, IR35 alone is merely adding ot the complexity, not simplifying it as it ought to.

Hot copying large mySQL databases
by Martyn Drake 28 Nov '01

28 Nov '01

Hi folks, Does anybody have any hints or tips for dumping or performing live backups of large mySQL databases? I've heard about mysqlhotcopy, but I think that's being a bit too simplistic for my needs.. Thanks, Martyn
