Install HBA without floppy during OSR 6 install  by (various authors)
- Install HBA without floppy during OSR 6 install. OpenServer 6 supports HBA installation at install time from floppy and from CD.
undefined fs_unregister fs_register sco 6  by (various authors)
- In OpenServer 6, -f causes extra memory checking instrumentation code to be generated, calls from which are then unresolved at link time.
Getting near to the end?   by Anthony Lawrence
- Well, the SCO lawsuit is getting closer to the end. According to the Groklaw article in the link, the judge threw out most of their claims. Too bad he didn't throw them all out, but.. Anyway, it's getting even less likely that SCO is going to do well here. For those who are still running SCO systems, time could be running out: the company may not be there when you need them to be. So what now?
Mysterious lockups   by Anthony Lawrence
- Of all computer problems, the unresponsive hang is the most annoying and most difficult to trace. There's no crash, no panic: everything just stops dead. The keyboard is useless, telnets just time out - you have no choice but to power cycle the machine.
Will NNTP fade away?   by Anthony Lawrence
- Will Google Groups kill NNTP? My bet is that in a few years nobody but a few die-hards will use NNTP.
Some common email problems  by Anthony Lawrence
- My friend says I sent him a virus! Maybe you did. It is possible for a computer to be taken over by malicious software which then sends viruses to other people. This happens behind the scenes; the owner or user of the computer may have no knowledge of what is happening behind their back. If you don't have up to date antivirus software on your computer, this could happen to you. But maybe you didn't. One of the odd things about sending email is that the sender can easily lie about who they are.
Open Source Code behind PoloMercantil   by Roberto Sedycias
- Anatomy of an open source roject: As we started the project of the electronic auction http://www.polomercantil.com.br, we knew that the proprietary software costs would be too high for our financial resources. Our only option then was to make use of Open Source Code softwares.
NT influenced by Unix   by Anthony Lawrence
- For several years now I've been looking for something Bill Gates said. Unfortunately I had misremembered the actual words, and every time I found someone who thought they remembered it, they had the wrong words too and I'd come up dry yet again. Finally this week someone in a newsgroup pointed me to this:
Google new groups beta   by Anthony Lawrence
- This is an old article about beta Google Groups and is only left here for historical purposes.
Isn't it time to really punish Microsoft?   by Anthony Lawrence
- Hasn't Microsoft's abuse of power gone on long enough?
Resurrection   by Anthony Lawrence
- If the survival of your long term descendants is of any importance to you, then - duh - of course we need to become multi-planet. Actually, we need more than that: we need to get out of this solar system before our sun goes away, and we need to get out of this galaxy before it collapses into its black hole center. If the Universe itself expands and collapses periodically, we need to find a way to survive that too (and people are actually thinking about such things even now).
Phantom Connections   by Anthony Lawrence
- Mysterious typing: I had coffee with Mark Jones of Micronet Network Services, Inc this morning. The purpose was to discuss some Unix and Linux customers he has, but of course we started swapping stories and I liked this one so much I had to share it with you
3.3 volt PCI slots, old drives and a long week   by Anthony Lawrence
- It's been a while since I've seen a non-universal PCI card, but of course that's what this old beast had. You can't put an old 5.5 volt PCI card in a new 3.3 volt system unless it's universal, so that's out. Hmmm..
Handling missing data   by Anthony Lawrence
- I have an old Perl project that goes out to a Government web site, ftp's some files, massages them in various ways, and spits out some output. Over time, the project grew, and now does more than it used to. To keep it generic and simple, let's pretend that originally it went out and got "temperature" files every hour. That was simple enough: about the only error condition would be the inability to get one or more of the files it wanted. My program simply kept track of what it actually got and only ran the rest of the process on new files.
The future of computer techs   by Anthony Lawrence
- Is there any future for service techs? The decreasing cost of systems and the difficulty of fixing rather than swapping does not help.
GoboLinux : breath of fresh air?   by Anthony Lawrence
- A fresh idea for Linux or a confused mess?: My very first reaction to GoboLinux was negative. The underlying idea of taming the Unix/Linux file system hierarchy with symbolic links isn't new: heck, SCO did that way back with their 3.2v4.0 release, and for exactly the same reasons (see the Software Storage Objects- SSO section at this link). Most of us in the field agreed that the concept was laudable in theory but failed in practice: too many places where it broke down. See Speaking of symbolic links...for some taste of that.
Choosing an information security services provider   by Michael Desrosiers
- tapping into a security service provider might be the best way to protect your company
Man vs. Machine   by Anthony Lawrence
- While we can't assume that there never will be a "Google Killer", I think we can safely say that no human based search engine will ever bring them down
No more Parallel/Serial?   by Anthony Lawrence
- The last few servers I configured for customers have no parallel ports, and the new laptop I just bought for my wife doesn't have one either. Both the customers and my wife were surprised, but I wasn't: almost all printing today in business is networked, and home class printers are usually USB only. Parallel is disappearing quickly.
Wrapper scripts   by Anthony Lawrence
- When a command doesn't quite do what you want. wrpaaing it in a tiny shell script is often the most simple answer.
New Linux virtualization option : KVM   by Drag Sidious
- KVM stands for 'Kernel-based Virtual Machine' it provides a simple way to have full hardware virtualization available for Linux users on machines that supports either the VT (Intel) or AMD-V/SVM (AMD) extensions for their cpus.
Granite Digital USB to SATA/IDE Adapter   by Anthony Lawrence
- Handy tool for techs mounts hard drives by usb: While this is definitely NOT the way you want to run an external drive for any length of time, it is sometimes very handy to have quick access to a bare drive that you just tore out of something and that isn't going to have a permanent home again. This can be for recovery, file transfer, or just sanity checking: if you are a tech, you want to be able to do this:
Invalidating the Linux buffer cache   by Anthony Lawrence
- How to actually test the disk drive to know that data really has gotten to the disk drive. This could be because you want to test the performance of the drive, but could also be when you suspect a drive is malfunctioning: if you just write and read back, you'll be reading from cache, not from actual disk platters.
First you open it..   by Anthony Lawrence
- How to open a Dell SX270. This morning I wanted to pull the hard drive from an old Dell Optiplex SX270 I have hanging about here. I looked the darn thing and saw that someone else had been this way before: all the screws had been removed from the case.. but as it turned out, that was a complete red herring. You don't need to touch a screwdriver to open this puppy. Well, maybe one, but I never saw it in, so I'm not sure. You do have to be brighter than I am, but just in case you are equally challenged, here's how you open a Dell Optiplex SX270.
Finding large files   by Anthony Lawrence
- Although it is getting harder and harder to run out of disk space, some of us still manage to do it. Whether it's yesterday you had all the space in the world and today you have nothing or the space just dwindled away over time doesn't really matter: you need to either add a bigger disk or get rid of some of the junk.
Cron is not working   by Anthony Lawrence
- Let's just get this out of the way first: when someone says cron is not working, it almost always is, and they have just misunderstood something basic. Usually that's not understanding the environment that cron scripts run under or that the machine was physically shut off at the time cron was supposed to do something.
