Why Intel killed its Optane memory business

Old Used Programmer Silver badge

Re: Sigh...

When I need either more than about 32GB of mass storage, or I'm concerned about I/O access speed, I run my Pi4s with an attached SSD.

For ones operating below those constraints, I'm using A1 class uSD cards. What I was hoping for from Optane (based on the early claims for it) was not the better speed, though that's not bad to get, but greatly increased number of times you can write to any given cell. Simply put, SD cards wear out relatively quickly if they are being actively used. Longer endurance in use as a root file system would be a desirable trait.

And here I was hoping that Optane, with high write counts, would make it's way into micro-SD cards. The specs looked pretty good for boot devices for Raspberry Pis.

Breaking VSAM in IBM COBOL

I wrote a COBOL program on an IBM mainframe that needed to extend a record in a VSAM KSDS spanned dataset. That's a valid operation (just read the VSAM manual), but it didn't work. I couldn't figure out why not. The systems programmers in our shop couldn't figure it out. The local IBM support folks couldn't figure it out.

So it go sent to the VSAM development group in (IIRC) the Netherlands. About 6 months later, we got a reply. While what I was doing was valid in VSAM, the COBOL compiler didn't implement it. So they were going to change the COBOL manual to say You Can't Do That.

(IIRC, my solution was to read the record, delete it from the dataset, build a new record with the same key, and add that to the dataset.)

Not everyone...

I'm still using Win 7. I'm *considering* building a Win 10 system, but only because it'd be very hard to get a copy of Win 7 and I'm going to be forced to use at least Win 10 at some point, so a low usage machine to get used to it on will be of some benefit. Doesn't mean that I *want* Win 10, let alone Win 11.

Re: Uniplex "my God, it chills me just mention the dark lord's name,"

Do you correct for locality? For any area controlled by England, the Julian to Gregorian calendar switch took place in 1752. Various other countries made the switch as late as 1923. The Orthodox churches still haven't converted.

Re: Uniplex "my God, it chills me just mention the dark lord's name,"

Those sorts of problems usually went the other way by thinking that all "00" years are leap years. It's true for the Julian calendar but not for the Gregorian.

I went around three times with a programmer that wrote a new set of standard date routines at a company I worked at. On the first pass, 1900 was a leap year. On the second pass, 2000 wasn't. The third try got it right.

One of my favorite trivia questions is: Could someone have been born on 29 Feb. 1900? It takes an additional bit of data to answer correctly. You have to know *where* they were born, but many, many people don't know that.

What's old is new again

My (late...as of two days ago) wife, Dorothy J. Heydt, had industrial VRs in her novel, "A Point of Honor", published in 1998. So it's not like no one thought of the idea before. (Hmmm....wonder if any of the people touting this read her book?)

Rather odd to use a picture of the BCM2836 for the article. That was the original Pi2Bv1.1 SoC. No Pis have been made using them for several years now. The Pi2Bv1.2 uses the BCM2837, same as the Pi3B/Pi3B+ and--in a different guise--the Pi02W.

Military implications?

One wonders what effect shifting to these slower, less capable, chips will have on Russian military hardware. What, for instance, does the yet to be mass produced T-14 Armata tank really need? All of this especially in light of their obvious need to replace a lot of--at least nominally--"smart" munitions that have been expended flattening Ukraine.

The joys of writting error messages...

I once logged an error message in a program where it should not have been possible to get to. The message was "Committing seppuku! Arrrgggghhhhh!" followed by the program terminating. One of my fellow programmers on the team managed (somehow) to trigger it. He came to my desk, looked accusingly at me and said, "You wrote this, didn't you?" I had to allow as how I had, so we went over the code together to figure out how he'd managed to trigger the message.

Re: Hire a few hundred thousand biplanes.

I think you mean WW1. The only biplanes in use in WW2 (that I know of) were the Fairey Swordfish (famed for its part in sinking the Bismark) and some Italian biplane fighters, with a top speed about 250MPH. Apparently Hurricane and Spitfire pilots were a bit embarrassed to admit when they shot one down. (Though at that, they were faster than Ju-87 Stukas, which flew about about 190MPH.)
