Getting past your own biases

Dave Farquhar Uncategorized , , , , , , , , , , ,

I read Andy Grove’s Only the Paranoid Survive last week. I always figured it was an autobiography or memoir, not a business book. But it’s a business book.  A very good one.

I avoided it because I didn’t like Andy Grove. I’ve never been a fan of Intel’s business practices during the 1990s and 2000s, including using payola to keep competitors’ chips out of large computer systems, but after reading this book, I’m more disappointed than anything. Whichever company had Andy Grove wins, period. No need to cheat. Read more

The Post-Dispatch may be giving the wrong idea about the dollar value of vintage computers

Disclaimer: I wrote this article back in 2014. I leave it here as a snapshot of the state of how things were in 2014. The situation at the time you are reading this is likely different.

Articles like Top 10 collectibles for value, from the Post-Dispatch this week, frequently make me nervous, mostly because of statements like this one:

[D]id you know that computer parts can bring home cash, too?

Statements like that tend to get people’s hopes up way too high. I find the timing interesting though, seeing as a TRS-80 Model 1 sold at a St. Louis estate sale this past weekend. The estate seller’s reaction? “Normally you can’t give that stuff away.”

IBM PCjr and Tandy 1000

IBM PCjr and Tandy 1000

On January 29, 1984, two computers hit the market. One was Apple’s Macintosh. It needs no introduction. The other was the IBM PCjr. It was a little less successful. We’ll talk about what this has to do with the Tandy 1000 in a minute.

The PCjr is one of the biggest flops in computing history. Few people know much more about it than that. It ended up being an important computer, but it certainly didn’t meet IBM’s expectations. Read more

Cutting through the fluff around the Target PIN breach

Dave Farquhar security , , , , , , ,

OK, so Target is back in the news, and it’s nowhere nearly as bad this time but there’s some posturing and some fluff in the news, so I’ll take it upon myself to demystify some of it. Some of it’s PR fluff, and some of it’s highly technical, so I’ll cut through it.

I’m just glad–I guess–to be talking about this stuff outside of a job interview. Like I said, this time the news isn’t nearly as bad as it could be. Read more

What on Earth is a Mainframe?: A review

Dave Farquhar Uncategorized , , ,

I’ve been reading David Stephens’ self-published What on Earth is a Mainframe, (also available on Amazon) which is as close to z/OS For Dummies as we’ll ever see.

I deal with mainframes at work from time to time. I interacted with an old IBM mainframe of some sort when I was in college, using it to get on the Internet, do e-mail for classes, and write programs in Pascal. That mainframe has been gone almost 20 years now, but it’s more mainframe experience than most of the people in my department have.

That’s the thing. Mainframes have been on their way out for 20 years–which was why Mizzou retired Mizzou1–but they aren’t any closer to the door now than they were when I was in college. I wouldn’t call it a growth industry, but there are some tasks that haven’t managed to migrate down to smaller iron yet, and if they haven’t by now, maybe they never will. But the universities aren’t producing new mainframe administrators–ahem, IBM calls them system programmers–so while it’s not a growth area from a numbers perspective, it’s a marketable skill that isn’t going away.

That’s where this book helps.

Hacker chasing, circa 1987

Hacker chasing, circa 1987

I’m catching up on reading. Next on my reading list is The Cuckoo’s Egg, (Amazon link), Clifford Stoll’s memoir of chasing down a computer hacker in the late 1980s. In it, he describes a very different world, ruled by mainframes and minicomputers, where Unix was something special, IBM still made PCs, but desktop PCs and Macintoshes only received occasional mention, and academia and the military owned the Internet, almost literally. And, oh, by the way, the Cold War was still raging.

The remarkable thing about this book is that it’s an approachable spy thriller, written in 1989, that explains computer security to an audience that had never seen or heard of the Internet. You don’t have to be a security professional to appreciate it, though it’s a classic in the computer security world–many people read it in the late 1980s and early 1990s and decided to get into the field.

The 11 Neff Hall chop shop

Dave Farquhar Uncategorized ,

I saw an IBM PS/2 Model 55SX at an estate sale this past weekend. It took me back to my first non-food service, non-retail job, doing desktop support at Mizzou.

Well, as a precursor to doing desktop support, they tried me out just building and tearing down machines. I worked out of Room 11, which was at the time a dingy, dark, musty place. But they pay was good and it meant I got to spend my time between classes taking computers apart all day, and that was nice.

My first assignment was to build IBM PC 330 and PC 350 computers to sit on professors’ desks. These were 50 MHz 486DX2s. They were a bit outmoded by then, but they were a lot better than what they were replacing, which was, in most cases, a PS/2 Model 55SX, which was a 386SX running at either 16 or 25 MHz. My second assignment was to disassemble those Model 55SXs, revert them back to their factory configuration, and sort out all of the add-ins so we could use them to upgrade other machines, and then, sell whatever was left as surplus.

Sculley on Jobs

Sculley on Jobs

John Sculley famously fired Steve Jobs in September 1985, a move that’s pretty universally panned today. Nearly 28 years later, Forbes asked Sculley about it.

Here’s the money quote:

“He was not a great executive back in those early days. The great Steve Jobs that we know today as maybe the world’s greatest CEO, certainly of our era, he learned a lot in those years in the wilderness.”

Bombshell: Ballmer steps down from Microsoft

I’m sure you’ve heard by now that Steve Ballmer is retiring. It’s time. If anything, I agree with the people who say he would have been better off retiring years ago. But I really didn’t expect it. In spite of the immense pressure to step aside, at least in public he never gave any indication of having any intention of doing so. Read more

Goodbye Amazon Affiliates, hello Viglink

Dave Farquhar Uncategorized , , , , , , , ,

I’ve been an Amazon affiliate for more than a decade, which meant that if I mentioned a product, posted a link to Amazon and someone clicked the link and bought it, I got a little bit of money. It didn’t make me rich, but in a good year, I made a couple hundred dollars, which paid for the upkeep of the site.

Well, Amazon and the state of Missouri are fighting, so Amazon is discontinuing the affiliate program for Missouri residents. The loss won’t break me, but by the same token, it’s nice to have that money coming in to pay for things like equipment upgrades. I found Viglink, and I’m going to give that a try.
