As far as I can tell they are for 8s. Please contact me off list if you are interested. REMEX 109381, one is a reader only,should be an easy upgrade reader/punch 109883 114143 / 114141 Thanks, Paul

> From: Paul Koning > while Unix is reasonably secure, application writers have managed to > create massive numbers of security holes that have nothing to do with > defects of the OS, and aren't cured by a better OS. On a secure system (i.e. OS plus underlying hardware), _nothing_ an application does (whether merely buggy, or guidely malevolent) can i) write data it's not supposed to have write access to, ii) read such data, iii) interfere with any another application, etc, etc. Google '"Roger Schell" oral history', and read that, and the other documents he mentions there. (By itself, it's a very entertaining and educational read, even if you ignore the others. It contains an interesting discssion on his contributions to the security mechanisms of the x86 - which I expect Intel will someday ditch, because nobody is using them - just like they apparently ditched segmentation in the latest x86 chips because nobody is using it. Sigh.) Yes, a buggy application won't work right, and may crash, but there's no way to prevent that (although better languages, and programming style, can help a lot). Noel

PAL on CDU-700 / 710 Unibus disk controllers

Many programmers, particularly the BP technologies ones, can read it Curious how you know it is not a protected PAL? The PALs are protected on all of the CMD CQD adapters I have looked at. I can't remember if I bothered checking the PAL on my CDU-720/M

Very sad message: the passing of Jon Johnston

Jon was always helpful always cheerful and never snarky this issad.... very sad indeed we have lost an ally. Ed Sharpe archivist for SMECC In a message dated 4/27/2016 10:09:08 A.M.

You mean not everybody does this? Alas, no, but that's really the point I was getting at with the comment about knowing multiple languages. It wasn't about the languages themselves or what value the variety itself brings. I pulled the half dozen number out of the air just because if I look back over any 6 to 12 month period of my career, I've used a good half dozen during that period. What's important to me isn't the effect on the candidate's programming; it's the independence, self-motivation, and curiosity that learning many languages represents. I also like to see evidence that the candidate recognizes that no skilled artisan's toolbox contains only a single tool. My biggest complaint about new grads is the view that all the world's a nail, because the only tool in their toolbox is a hammer. BLS

Mac "Workgroup Server" (or "network server") hardware & AIX

by swiftgriggs＠gmail.com

Has anyone ever seen either A/UX or AIX running on an Apple Network Server or Apple Workgroup Server? I had several hundred AIX machines running in a server farm for a while, but even the oldest was POWER4 based, and I've only done a bit of legacy support for PPC60x-based RS/6000 systems. I don't belive I've ever seen an ANS or AWS IRL. I'm curious what the last version of AIX that will run on them. I'm guessing 4.x. I'm also curious if there is one machine that can run A/UX, AIX, MacOS, and NetBSD. Here's a fun fact to know and tell. In addition to an SGI Irix screen running the "fsn" tool in the movie Jurassic Park, there were several screenshots of a workstation in that same room/scene running A/UX. -Swift

IMHO, Just > because I point that out, doesn't make me "foolish, ignorant, narrow > minded, or short-sighted" I usually try to stay out of such discussions, but I think it's important to draw some distinctions here. First, it's not pointing out which languages/techniques are popular that's narrow- minded and short-sighted. It's the view that popularity and "commercial viability" is the primary consideration of value in education that's narrow-minded and short-sighted. Second, it's the perspective that's narrow-minded and short-sighted, not the person who expresses that perspective. Many people fail to appreciate the distinction between training and education and as a result see the primary purpose of the university to be job preparation. That so many people misunderstand the purpose of the university isn't a reflection on their individual intelligence or priorities. It's a reflection on the misplaced priorities of the secondary education system and of society as a whole. It's the same misplaced priorities that lead so many students to be so obsessed by the most meaningless part of the system: grades. BLS

No more three national TV channels (in the US, replace '3' in other countries.) Yes, there are issues, but on balance, I think I still prefer post-Internet to pre-Internet. > the vapidity of online exchanges quickly reached fever pitch as more > and more blockheads flooded the network.

Real world strip malls, Walmart, etc exist because of _demand_. If people didn't want that stuff, it wouldn't exist. You want better?

Uhh, by the time we got to that stage, the taps were long turned off. All the 'space handed out freely' stuff happened back when you went to Postel for numbers - and a lot of the class A's went i) before the Internet was a going concern, and ii) in the earliest days, there were _only_ class A's. > Nowadays, folks create viruses that encrypt and/or destroy the target > for ransom the minute they can write 3 lines of code in Visual Basic. > The level of malice and thuggery have gone way up.
