If you need an expert on the long-discontinued Motorola 96002 digital signal processor, I'm your guy! I wrote an entire graphical operating system in its assembly language and still need to maintain it from time to time, so my skills remain sharp.

Slow loris. They have this look like they're scared and want to be cuddled, and if they could speak, they'd probably say "Oh my, did I forget to tell you I'm the only poisonous primate?"

You can always combine integer operations in smaller chunks to simulate something that's too big to fit in a register. Python even does this transparently for you, so your integers can be as big as you want.

The fundamental problem that led to requiring 64-bit was when we needed to start addressing more than 4 GB of RAM. It's kind of similar to the problem of the Internet, where 4 billion unique IP addresses falls rather short of what we need. IPv6 has a host of improvements, but the massively improved address space is what gets talked about the most since that's what is desperately needed.

Going back to RAM though, it's sort of interesting that at the lowest levels of accessing memory, it is done in chunks that are larger than 8 bits, and that's been the case for a long time now. CPUs have to provide the illusion that an 8-bit byte is the smallest addressible unit of memory since software would break badly were this not the case, but it's somewhat amusing to me that we still shouldn't really need more than 32 bits to address RAM at the lowest levels even with the 16 GB I have in my laptop right now. I've worked with 32-bit microcontrollers where the byte size is > 8 bits, and yeah, you can have plenty of addressible memory in there if you wanted.

I know a google engineer who was saying they're having to update their code bases to handle > 16 exabytes of storage, if you can imagine. But yeah, that's storage, not RAM.

Most recently? My wife was wfh and out of the kindness of my heart I brought her a coke. She was on a zoom call with her entire team. I was pantsless.

I started in C and switch to C++. It's easy to think that the latter sort of picked up where the former left off, and that since the advent of C++11, it's unfathomably further ahead. But C continues to develop and occasionally gets some new feature of its own. One example I can think of is the restrict key word that allows for certain optimizations. Afaik it's not included in the C++ standard to date, though most compilers support it some non-standard way because of its usefulness. (With Rust, the language design itself obviates the need for such a key word, which is pretty cool.)

Another feature added to C was the ability to initialize a struct with something like FooBar fb = {.foo=1, .bar=2};. I've seen modern C code that gives you something close to key word args like in Python using structs. As of C++20, they sort of added this but with the restriction that the named fields have to come in the same order as they were originally defined in the struct, which is a bit annoying.

Over all though, C++ is way ahead of C in almost every respect.

If you want to see something really trippy, though, have a look at all the crazy stuff that's happened to FORTRAN. Yes, it's still around and had a major revision in 2018.

So the next captcha will be a list of AI-generated statements and you have to decide which are bat shit crazy?

Fair, though I guess my interpretation was that void* is kind of like a black hole in that anything can fall into it in an unsettling way that loses information about what it was?

"Recall uses Copilot+ PC advanced processing capabilities to take images of your active screen every few seconds,"

Seems like a lot of extra disk thrashing that would shorten the life expectancy of an SSD? Like it would be considerably more than your usual background chatter of daemons writing to log files and what not. Unless I'm misunderstanding this?

Several years ago, I went under the knife and the whole day from the point they put me under is a total blank. It's unsettling because I am told I carried on conversations with the doctor, family members, etc. after initially coming to from anaesthesia, but it's only starting the following morning when I woke up in a regular hospital bed that I could start remembering again.

I totally get where people are going with eliminating dictators and what not, but knowing myself as well as I do… yeah, you'd probably find me down at the Chinese buffet.

I had to sleep on this before coming up with a reply. As an individual who is not what you would call religiously devout, you can take it with a grain of salt. But whatever the case, here goes…

I grew up without religion for the most part but married a Catholic, and as musicians, we wound up playing at the local church.

As it stands, I would not say that I have bought into the whole religious faith thing at the deepest levels. That does not come easily for me. But I think it is fair to say that certain aspects of the religious experience have rubbed off?

In particular, I am more invested in the welfare of others ranging from my immediate family and friends (many of whom I met indirectly through church connections) to the community at large. As such, I am in no hurry to shuffle off at this point, as I feel there are people who depend on me and so I guess I still have unfinished business?

I don't know what happens in any afterlife. Does anyone, really? Frankly, if we all just fade away into oblivion, I'd be satisfied to simply have a peaceful release from worldy concerns, but I don't have any expectations beyond that.
