Computing went through a mad pace of change between 1985 and 2000, from 8-bit computers to 64 bit becoming relatively affodable with Alpha chip.
I went from doing BASIC on my Spectrum 48k as a kid to running multi-user systems on Intel/AMD architecture.
Meanwhile, the last 15 years in user-end hasn't that much advanced. Yeah, more cores, more RAM but I've already had more than 4GB RAM on my PC in 2010, and even now that's quite OK with Linux.
@M0KHR @azonenberg @whitequark @datenwolf I think the 486 66DX2 was the first x86 CPU with the core clock decoupled from the external bus (hence the DX2). At the time, I thought that was cheating…

I prefer the version with a RAID0 from 4 microSD cards -
@RedstoneLP2 @jn @whitequark I recently found an sff thinkcentre in front of an e-waste bin, no ram of course, ddr4 is gold these days so it's possible it was kept by the previous owner. i had some laptop ram to spare, so i did purchase these adapters. i can only use one slot, the other module would not fit due to the presence of the drive cage (and even the one i can use is sort of rubbing against the fan shroud, but it works, so whatever.)
@RedstoneLP2
On second thought, it could have also come from a nearby business, those also sometimes have media destruction policies that involve RAM. (Nobody tell them CPUs have cache and various onboard microcontrollers and stuff have some RAM too.)

There were shenanigans about bus vs CPU bits (386SX33 and 8088 comes to mind)

@whitequark @datenwolf those came angled in 2 different directions so you could install 2 of them.
Indeed. That's why I explicitly called out that I used a pair of them. I maybe should have clarified what I meant by "pair".

@whitequark What's old is new again:
Back when I built my Pentium-1 I carried over several MiB of RAM on SIMM modules to those new-fangled DIMM slots using a pair of SIMM→DIMM adapters:
@datenwolf @whitequark Somewhere around here I have some 30-pin to 72-pin FPM adapters as historical curiosities.

@ozzelot @jn @whitequark meanwhile i'm surprised when a storage device is actually wiped for once
@RedstoneLP2 @jn @whitequark I'm not saying such companies are around that bin, just saying they exist in general. Probably. They're heard of.

@whitequark fuck that's depressing… -
@tom_verbeure @whitequark @M0KHR @datenwolf It's funny how everyone else who grew up in the same time period has all these formative memories of playing games on 95/98 etc and I never had that.
I was doodling in 16-bit PBRUSH.EXE and writing C in EDIT.COM
@azonenberg @whitequark @M0KHR @datenwolf I don’t think anything will ever match the hype when Doom was first released. There must semiconductor companies out there whose entire existence is due to the spike in demand for network cards.

@whitequark @elexia suddenly buying a laptop with soldered ram is both great and awful (great if buying second hand now)

@azonenberg @tom_verbeure @whitequark @M0KHR @datenwolf My first computer was a second hand 386SX20 running MSDOS 5.0 in 1994. I quickly upgraded the 1 MB of RAM to 4MB and installed a Mitsumi FX001(S). It was basically a DOS machine, even if it had Win 3.1 installed. I was never much into gaming but rather wrote programs in assembler using debug.exe (Ralph Brown's Interrupt List FTW).
First new machine was a K6-266 with Win98 in 1998 (but still no games, Winamp, DivX and the like...) -

"3com" maybe? You know, the NIC manufacturer who cheaped out on MAC address allocations and reused MAC addresses for cards sold in different geographical regions.

@datenwolf @tom_verbeure @azonenberg @M0KHR that must be standard practice now, isn't it? does anybody promise globally unique hwaddrs?

@whitequark @tom_verbeure @azonenberg @M0KHR
MACs are 48 bit. So far there's still enough address space left for no collisions to be neccessary. And since bad things happen when you have an MAC address collision within a network segment, and the likelyhood of that only going up: I hope that 3com was an outlier.
3com bet on their doubly assigned cards to never meet in a shared broadcast domain. It happened within months.

@datenwolf @tom_verbeure @azonenberg @whitequark
Oooh, I had a batch of those once! Installed on a couple of office computers as a 100Mbit upgrade, and then they didn't work thanks to collisions! No wonder they were cheap.
Edit: actually they weren't even cheap. I remember jumping into my car and driving to Dixons to grab a bunch of cards to replace them because they were needed *now*

@datenwolf @azonenberg @whitequark @M0KHR Way too expensive! All I remember is that they were NE2000 compatible but Novell was too expensive as well. We used a single coax cable instead of UTP.

Yep, they work as long as you have the space for the adapters.

Gli ultimi otto messaggi ricevuti dalla Federazione

One of the most interesting areas of exploration in the ActivityPub community right now is the ActivityPub API. Most people who know ActivityPub are familiar with its federation protocol, which lets social networking servers like Mastodon and Pixelfed share data between them. But there is another, closely-related feature in the same specification, called the "social API".
ActivityPub has five normative sections: 3 Objects, 4 Actors, 5 Collections, 6 Client-to-Server Interactions, and 7 Server-to-Server Interactions. 3, 4, and 5 provide a read-only interface to social data that is useful for both the federation protocol and the social API. It lets both clients and servers read information about users on the network, their feeds, and the things they make and share.
Section 6 is focused on the mechanism clients can use to create new activities, and the side-effects of those activities. "Activities" are the most important data structure in ActivityPub (which is why they're featured so prominently in the name!). They represent sentences or statements about things that happen on a social network, like "Christine created the image img123.jpg" or "Evan liked Christine's image img123.jpg" and "Amy shared Christine's image img123.jpg". Creating these statements is how clients can make things happen with ActivityPub.
Section 7 is focused on how and when servers can send these activities across the network to other servers. There are some side-effects that are laid out, but mostly they involve cache management.
So, here's the important point I want to make: the federation protocol which connects ActivityPub servers is defined in sections 3, 4, 5, and 7. The social API is defined in sections 3, 4, 5, and 6. But some people use "server-to-server" or "s2s" as a synonym for the federation protocol, even though "server to server interactions" only covers one section. Similarly, some people use "c2s" or "client-to-server" as a synonym for the social API, even if "client-to-server interactions" is only one section.
I prefer to use "social API" or "ActivityPub API" to refer to the entire part of ActivityPub that lets client apps talk to social servers. Here are some rough reasons why.
It's what the spec calls it. In the conformance section, we said that 'this specification defines two closely related and interacting protocols: A client to server protocol, or "Social API" [...] A server to server protocol, or "Federation Protocol"'. This was intentional; the names come from the Social Web Working Group charter deliverables. Making a Social API was a key goal of the group. The ActivityPub API satisfies that goal.It's a term that all developers and many users are familiar with. People who've used mobile apps or third-party apps know what an API is and what it's for. If you use "c2s", it's not clear to most developers what you're even talking about.It's accurate. The social API is a RESTful API that uses JSON, HTTP, and all the fun stuff that app developers are already familiar with.It emphasizes what's already available. People often say that Mastodon does not implement the ActivityPub API. But it implements sections 3, 4, and 5 of the specification – it has to, in order to support the federation protocol. That's the entire read-only side of the API. All (almost all?) Fediverse servers support these parts of the spec, too. You can build a pretty OK read-only API client using what's already available from Mastodon and others; see https://acct.swf.pub/ for an example."c2s" doesn't cover the whole API. As I said above, only one section of the doc is called "Client-to-Server Interactions", and it doesn't cover the read-only side of the API."c2s" is insider jargon. c2s isn't a common term for RESTful APIs. It really isn't a common term at all; there are only a few protocol suites, like XMPP, that refer to the "c2s" and "s2s" part.I think it's fine if others use "c2s" when talking about the API, or especially about section 6 of the ActivityPub spec. It's not going to cause any harm. But the Social Web Community Group task force on implementing the API is called the "ActivityPub API" task force. I think that's a good idea – it emphasizes the API. I intent to use this name and framing for the foreseeable future.

Emulated FP64
Choosing the right news sources is important. In my case Hacker News 50 proved to be precious as in this recent post/toot/message they proposed "Fifteen Years of FP64 Segmentation, and Why the Blackwell Ultra Breaks the Pattern".Briefly, modern consumer GPU has a 64:1 ration in FP64:FP32 performances (FP64 is a shortcut for Double-precision floating-point number format).
