Our affair with Apple Computer

Apple will be celebrating its 50th birthday in April. Fifty years since the company was formed to sell simple computer kits designed by Steve Wozniak to local computer hobbyists in and around Palo Alto.

Meda and I jumped on the Apple bandwagon not long after the introduction of the Apple II in 1977, probably late that same year.

I knew nothing about computers. When we were in college, “computer” meant the room of electronic equipment in the administration building where an anointed few had access. The rest of us used fancy addling machines. Even handheld calculators were still in the future.

But I had been reading that these new “personal” computers would be fundamental “game changers” and wanted to learn more. I finally convinced Meda that we should just buy one and see what it could do, and we did.

That was the year we turned 30, and over the next nearly 50 years we have remained firmly in the Apple camp.

The original Apple II introduced what became the familiar beige case with an apple in rainbow colors. It had very limited memory, no disk storage and no built in software. The few programs that were available for purchase came on standard audio tape cassettes. You would plug your cassette player into a port on the computer and manually download each program. I remember the thrill of playing “Little Brick Out” at the Apple II’s slow speed after loading it from a cassette. It was like magic!

I can date our first Apple purchase by the use of cassette tapes. A year late, in mid-1978, Apple introduced a floppy disk drive priced at $600. It stored what was then a dramatic amount of data–113K, that is, kilobytes. It seemed to open up whole new worlds.

The following year, Apple introduced the Apple II+. We quickly got on that bandwagon via a Bell & Howell black Apple II+ manufactured under license for the education market. One day we walked into a small Honolulu computer hobbyist store and saw a stack of black Apples, and took one home.

That same year, 1979, saw the introduction of Apple Writer and VisiCalc, which turned the hobbyist-oriented Apple II into something that could do real work!

A few years later, Apple added the Apple IIe, with more memory and other features.

By that time, we had yielded to the “need” for his and her Apples at home, along with Apple’s for our office desktops as well.

Apple added Macintosh in 1984, but we didn’t invest in the new computer until the Macintosh Plus was introduced two years later. Unfortunately, the mists of time have erased any memory of which exact models followed as the first Mac Plus was replaced with newer iterations.

We invested thousands of dollars in new Macs over the years, more than I can recall at this point. Each made us more productive, or perhaps simply more efficient.

But it’s fair to say that our affair with Apple changed our lives for the better.

So I’ll simply say, Happy Anniversary, Apple!

An automated collision avoidance system warned of a close call

A reader writing as Pete808 left the following comment, which appears to provide additional details showing why our United flight to SFO on March 21 abandoned it’s initial landing attempt and powered up, went around, and made another landing attempt (this second one was successful).

Pete808’s findings show how much information can eventually be gleaned from existing public data.

Here are his findings, which initially appeared in a comment but are being elevated here because of their importance.

Here’s what I found by doing some additional internet research. By the way, I have no training or experience as a pilot or air traffic controller, although I’ve flown to SFO quite a few times.

In any event, one can go to LiveATC.net and listen to or download the archived air traffic control recordings for SFO for March 21, 2026. The archives are in half hour segments. After what seems to be a routine clearance to land, the archive for “SFO Tower” has a very cryptic communication from UA 373 a little more than halfway through the recording covering the time period beginning at 2200Z (Zulu or UTC time which is 3 pm SFO time). UA373 indicates that he’s going around although I couldn’t really tell what was being said by listening. In response, the tower controller tells UA373 to fly the runway heading and eventually to contact NorCal Approach.

If you review the archive for NorCal Approach for the period starting again at 2200Z, at around 23:45 into the recording the controller asks UA373 to say the reason for the go around and UA373 replies that they were responding to an RA. An RA is apparently a Resolution Advisory from the ACAS system (Airborne Collision Avoidance System), which is an onboard aviation safety system designed to prevent mid-air collisions by independently detecting nearby aircraft and advising pilots on avoidance maneuvers.

Although two planes landing on parallel runways is pretty routine at SFO with the aircraft required to maintain visual separation, the instructions with respect to ACAS Resolution Advisories is to do what the RA says. So even though UA373 was supposed to maintain visual separation from the other aircraft and even if that visual separation was still being maintained by UA373, when the RA was given by ACAS, the crew of UA373 was obliged to follow it.

Hope your health issues get resolved favorably.

A nocturnal adventure

Some of you might find this of interest.

I found myself in a very immersive dream, probably somewhere around 2 or 3 a.m. on a night not long ago.

The dream was very much like a movie in which I was a first-person narrator.

As I recall, I had infiltrated a strange religious cult along with one other reporter. I remember walking through a group of flower-child types who were off in their own worlds, with an occasional hard character with a predator’s gaze, probably the flock’s keepers.

I have no recollection of why we were involved in an undercover investigation of this cult, but I felt vulnerable and a bit worried as we collected observations.

At some point, I was talking to a couple of cult members, and one showed me a flyer challenging some of the cult’s primary beliefs. I pretended to be shocked, but it was something we had written and dropped around in an attempt to cause some disruption of internal discipline.

Seeing the flyer made me realize that they were looking for the source, and decided it was time to get out.

I recall strolling over to the back exit, where it was necessary to go through a small obstacle course before leaving. I managed that task and tried to look casual as I walked away from the property, but within a minute or so I started running to get as far away as possible.

I found myself running parallel to a low berm to my left, away from that exit.

Then I noticed one of those predator-types running off to my right, cutting across the field that separated us as he tried to intercept me. He soon caught up and to evade him I threw my body to the side, over that berm.

And BAM.

It was a rude, startling, and somewhat painful awakening as I found myself stretched full length on the hard wood floor on the side of our bed where I had fallen.

I landed along my right side, right arm, elbow, and shoulder, and right knee, but then rolled over flat on my back as my brain caught up with my situation. A few deep breaths and I began a quick assessment. Lots of parts were sore, but nothing seemed broken. Meda was now awake and also assessing my situation.

Luckily, after a minute or two of self-assessment, I was able to sit up, get up on one knee, and then stand, before getting back into bed and going back to sleep.

Part of this is our own fault. During our entire marriage 55+ years of marriage, we have shared a double bed. Right. Not King, not Queen. A plain old double bed, usually shared with a cat or two, pushing the two of us to the sides.

Is that what they term “living on the edge”?

I’m not sure what psychological term applies to this crossover between dream and reality, where parts of the dream “break out” into real world movements.

Yes, I searched online. Most descriptions say there is usually no memory of the content of the dream. In my case, the opposite. A clear memory.

As far as I know, this was the first time I entered this particular space.

Now when I feel myself entering a similar deep sleep dream state, I try to escape toward the surface of consciousness, just in case.

More details surface on our apparent close call

I am indebted to a reader who identified themselves simply as “Researcher” when leaving the following comment.

I had intended to post this earlier, but it was apparently lost in yesterday’s preparations.

I’m not an aviation expert, so please verify the data below before making conclusions.

ADS-B Exchange appears to show the other flight was a CRJ-200 operated by SkyWest as Flight 5974 from Fresno Yosemite International Airport. At about 3:16 pm PDT, United 373 and SkyWest 5974 were both approaching the airport at an altitude of about 1075 feet. It appears United 373 was gaining on the SkyWest, since it was traveling about 24 knots faster. SkyWest was to the front right of the United.

According to the Wikipedia entry for SFO, “aircraft may safely land side-by-side essentially simultaneously on 28L and 28R while maintaining visual separation.”

Here’s a screenshot of the track from ADS-B Exchange:
