Carry on using IPv4 on internal networks and deploy IPv4->IPv6 translation gateways at your borders.
From the point of view of addressing, at least, IPv4 is fine for internal networks, but IPv6 may be necessary for new hosts/mobile devices and backbone.
...have pretty good support; Readable English manual, BIOS updates "for ever" and even semi-official hardware mods when an unanticipated development is made in peripherals...
If you're in an old house or one that's improperly wired, the ground on one end of a serial cable may be at a different potential than that of the other end!
Twisted pair ethernet is designed to handle a potential difference, seeing as how in its designed implementation, it often runs from one end of an office to another, etc. But I'd trust coax ethernet less: I've been zapped a time or two, touching the BNC connector and the chassis of a computer at the same time.
Also, something I picked up on is that ethernet shouldn't be run from one building (they might be on a different supply that's out of phase relative to the other building's supply) to another over an electrical medium as there will be a potential difference.
PPTP, like most Microsoft protocols, was designed to allow them to market a product before everyone else had agreed on a fully open standard. That standard is IPsec and FreeS/WAN is (AFAIK) the only implementation of that for Linux.
Alternatively, for other readers who are prepared to spring for a commercial solution, V-One's SmartGate product springs to mind. It also implements IPsec and is supported on RH6.0.
Counterpane, Bruce Schneier's company, has a few papers on PPTP and IPsec on their website.
Importantly, Guildford is also the home of Red Hat UK.:)
Reading is the home of Microsoft UK.:-P:-P
As a Reading-ite, I would say that the Thames Valley area is one of the UK's biggest IT-hotspots, but a lot of it is sales-related, rather than techie-related, unlike, say, Cambridge.
Also, Reading seems to be unusual in that most of the high-paid IT/Sales/Marketing jobs are taken by outsiders, leaving the locals to (try to) pay their excessively high mortgages on 'ordinary' salaries. This seems to create quite a divide and tensions result and sometimes result in violence or vandalism.
'Normal' towns seem to have a more graduated distribution of wealth, which seems to result in less envy and fear.:(
Badly-built RPMs will incorrectly modify permissions, just like badly-build.tgz archives will. But you check.tgz archives before you install them, right? So why didn't you rpm --qlvv the i386.rpm before you installed it? And did you submit a bug report to the packager? Was the package even intended for your distribution? If it wasn't, it may not work anyway if the shared libraries are of differing versions.
RPM has a great number of advantages over the package management Slackware (used to) do (I used Slackware back in 2.2.0 days and moved to Red Hat because I saw the advantages RPM offered). Can you find out which package 'owns' a given file? Can you determine which files in a package have changed since installation? Can you determine which packages might break when you upgrade a given shared library? Can you easily rebuild a new version of the package in exactly the same way Pat Volkerding did using the same compile-time options? Certainly none of these were possible in the Slackware 2.2.0 days...
Properly-built RPMs should be relocatable (--installroot) providing there aren't static paths in the source (not really RPM's problem, IMHO).
Patching of RPMs could be done by rpm -ivh --force installing an RPM that only replaces one or two files. --verify will fail for the old package on the files that were replaced, but that's expected.
RPM does preserve files tagged as %config in the.spec file. If an RPM you use doesn't preserve the config, submit a bug report to the packager.
The only thing I wish RPM did do (and it could be made to do it using postinstall scripts) would be to merge your changes to the config relative to the old config into the new config file. But I realise that there's a big can of worms to be opened just down that road...
- Alan Cox mentioned that Alcatel (BT's chosen supplier of USB ADSL modems for their recently-launched OpenWorld ADSL service) are independently working on Open Source drivers for the modem.
- SGI are totally Gung-Ho about Linux. Really. Linux will be the only OS to run on their IA64 (Merced) boxes. They're publically committing themselves to supporting their existing MIPS/Irix customers, but they definitely believe their/future/ lies with IA64/Linux. I do hope this strategy works out well for them. I'm slightly disappointed that their recent IA32 boxes have lost the innovative chipset that was included in their original Visual Workstations. Essentially the new models are well-built AT PCs, with a bleeding-edge nVidia graphics card.
- VMware now have an office in Henley-On-Thames in the UK.
- Debian emphasised the difference between Free Software and Gratis Software by charging 7UKP for their 6-CD distro set, but giving away Free Beer. I hope the irony wasn't lost...
In the UK, a large proportion of the IT industry is based around the corridor created by M4 motorway in towns like Swindon, Reading, Bracknell and Slough.
Salaries are similarly inflated compared with the rest of the country, skills shortages are rampant as are places to live. Rent for a 2/3-bed house will run to about 600-700UKP per month, plus bills. A nice 1/2-bed apartment is about the same and a nice house will cost you 1000UKP plus. House prices are have risen about 30% in the 3 years I've been living here and a reasonable 2/3-bed house in a nice part of town will set you back 130000UKP+.
Now I've a achieved a reasonably competitive Silicon Corridor salary, I'm tempted to move back to my hometown where house prices are about 50% of what they are here; but the jobs aren't as interesting and besides, all my friends are/here/ now...
As Linux becomes more accepted, Red Hat will have to learn that old school UNIX vendors aren't going to put up with that shit. I love GNU/Linux, but it can't yet do as much as you think. There are very good reasons why you don't see SunOS and AIX users running to Linux in throngs.
Er... AIX uses backup/restore archives for its' packages which can be bodged into the system manually, but should be installed using smit.
Solaris uses.pkg files, which again, should be installed using pkgadd.
Can someone please explain why RPM is so evil? Why is is so unreasonable to ask people to use rpm2cpio when I'm quite prepared to take time building RPMs for myself when only tar.gz files exist?
Well, many of us probably started on 8- and 16-bit home micros (which aren't available any more), so why not do the same thing and start with an emulator of an 8-bit machine - this has the advantage that there isn't too much to learn about the environment before they can start programming, unlike Windows or DOS or UNIX or...
I'd suggest a Spectrum/Timex emulator, but that's just me...
Well, yes, SCSI/is/ better than IDE (duh!) but if you include a value-for-money rating, in all but the most extreme circumstances, IDE can't be beat. Oh, and with (U)UMDA enabled and Linux's IDE drivers, the only technical advantages SCSI has is devices being able to disconnect when performing a/single/ long operation such as a tape rewind (/not/ a CD write!) and all devices hang off the same single IRQ.
I've been using a Mitsumi CR-4801TE (4x write, 8x read) with Linux for about two years. The only bad burns I've had have been when I've been attempting to copy 'tricky' stuff to see how difficult it was. I've come to the conclusion that having a CDR drive that can do DAO and using a/good/ CDROM drive (mine is cheap n' nasty) are about the most important factors.
Under Linux, the ide-scsi pseudo driver works just fine. I use cdrecord to write, mkisofs to create the images and gcombust if I'm feeling lazy and want a nice GUI (see freshmeat for all of these apps).

I've had one since December last year and I think it's pretty good value for money. It's not as good as the high-end digicams (e.g. Nikon Coolpix, Olympus 2000Z) or a quality film camera, but it's a good digicam point-and-shoot equivalent. It works well with gphoto too, which was a must for me. The focus has been criticized as being somewhat soft, so try it on some mid-long range shots to see if you notice - I didn't at first, but I'm beginning to now. I don't regret buying it though as I was (and still am) new to photography, so I didn't want to spend much money to begin with.
It may not work on Alpha, but I doubt this will be the reason. That "something" is a chunk microcode which runs on some processor on the card itself, probably a DSP...
On a more serious note, what would be nice is if there was a set-up that noticed a portscan in progress and blocked that IP (plus notified the administrator etc). Anyone know of something like this?
Whilst this sounds like a good idea, and can be done using most IDS/firewall combos (e.g. RealSecure from ISS or NFR from... er... NFR, in practice most admins shy away from using it for fear of it being turned against them and their networks (think spoofed attacks that appear to be from the "victim's" business partners).
It's been a while since I've done anything with Irix, but I do remember that I was glad I knew a decent amount of UNIX when I was playing with it. Hell, one of my superiors had a fit when I changed the order of the FQDN and 'naked' hostname in/etc/hosts causing the machine to fail to boot next time we lost power. GUIs won't save you from that kind of problem.
Oh, and TiVo would be classed as an "Information Appliance" by my standards, so I would/hope/ that it/would/ be easy to use.:)

Already in StarOffice 5.2! Try it and see... use the 'link' tickbox when inserting graphics from a file (specify a URL as the source).

Instead, you should use fibre between buildings.

You're thinking of _Kevin_ Warwick.
Can anyone provide references to show that MySQL's implementation of transactions IS inadequate/incomplete?
(that's not just rhetoric; I really would like to know why!)
Hint: he doesn't like it. And neither do I.
