This is very useful for finance, less useful for scientific and engineering. But then, I suppose that IBM has targeted the z14 at the financial sector.

What appeared to you as, say, US dollars with two decimals, was internally treated as integer cents; the decimal point between the dollars and cents were inserted in the output process, but never seen at the internal level. I have never programed Cobol, but I have used the scaled integers many, many times in industry automation. Int only needed 16 bits, float 32 bits (space was an big deal in some projects) and was pretty difficult to be read in binary / hex due to the intern composition.
I used BCD manay times too, but not that much in comparison (specially with 8-Segments displays and to avoid some weird formats due to endianness and signed/unsigned values)

Well, hopefully your electrons won't leak away, so your memory will be intact tomorrow.
And cool article btw.

Doesn't that depend on whether he uses DRAM, SRAM, or NVRAM, and on whether the hamsters power him down until tomorrow?

If you want to fix your phone without going back to the manufacturer, you’re increasingly in luck. Not so much if you’re a company that’s keeping up old software. You bought it - you fix it

Terminology is important. I've been in design meetings where people were in agreement, only to later discover that they meant different things. And the opposite: heated debates where it turned out that both sides were proposing more or less the same thing. As much as anything, the patterns movement did everyone a favor by creating consistent terms for various design techniques. It saves lots of time during design discussions.

Greg's point is excellent. Mine is, well...
Given that the author cites three resources:
Design Patterns & Refactoring
Catalog of Patterns of Enterprise Application Architecture
Refactoring
And we can summarize those into the terms "Design Patterns", "Enterprise", and "Refactoring", so when n00b programmers ask me what those are / mean, I usually respond that they are just BS terms for common sense, building your code so more than one user can use it at a time, and making code changes.
No "spidey-sense" needed. Just jaded 40 years of programming experience.

"We appear to be entering a period of Windows' development where we can expect new features and tweaks to come to the operating system several times a year. "
This scares me. Every significant update (according to Microsoft) has a tendency to reset some settings back to their defaults. Oh joy.

Like any spacecraft, the telescope has encountered micrometeoroids and its sensors have detected six deformations on the telescope's primary mirror panels that have been attributed to strikes. Well, it was nice while it lasted

The article says the telescope is still functional, although its data will be less accurate.

I assume (== hope) that NASA et al.'s statistical model for hits took into account that the L2 point would tend to collect (and lose) debris at an enhanced rate...

I'm willing to wager that they took that into account.
The article refers to them using computer modelling to predict the possible strikes, and it says that the modelling was wrong.
Sort of boosts my confidence in climate models, to be sure.

It does NOT say the model is wrong.
Quote: "It is not yet clear whether the May 2022 hit to segment C3 was a rare event," the document said.
There could be a chance that it was "an unlucky early strike by a high kinetic energy micrometeoroid that statistically might occur only once in several years" the NASA team considered.
But potentially "the telescope may be more susceptible to damage by micrometeoroids than pre-launch modelling predicted".
A strike this large and this early in the mission is something the model says is unlikely. Either there's a lot more crap floating around L2 that all the other telescopes we deployed there[^] were lucky enough to avoid the worst of, or Webb threw a handful of dice and got all 1's.
The other probes at ESL2 have ~30-40 years of combined operations time; so either Webb has has a really bad luck first few months, or everything else has had decades of good luck. One of these is more likely than the other; unfortunately it's not the one that allows writing overwrought headlines.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?
