My @raspberrypi.com 500+ Ethernet port has massive packet loss running at 10baseT. Switched to a USB Ethernet device and it’s OK. Cost me 90 minutes in debugging DNS for my #retrocomputerfestival exhibit :/

🦀 I've improved the implementation behind all the string formatting macros in Rust: println, panic, format, write, log::info, etc. (Everything using format_args!().) They will compile a bit faster, use a bit less memory while compiling, result in smaller binaries, and produce more efficient code! 🎉

PowerPC fans get really upset if you’re rude about the favourite chip. Also, if you post a video on Reddit no one watches it and they just kick off based on what they imagined it said based on the title.

Was PowerPC ultimately a failure?
Asianometry makes a compelling argument for Yes.

Did you know that before Sega bought the rights, Columns was a demo bundled with HP's UNIX?
I have it running on a 68030 based HP 9000. But it's doing it by booting over the network from a PA-RISC machine, and they share the same root filesystem. How?! Well.

I will be there, with a collection of incredibly expensive 90's UNIX workstations that you were absolutely not supposed to be gaming on ... but we're going to anyway.
Oh wow, this time next we'll be in full swing! Tickets for the Saturday are close to selling out - www.computinghistory.org.uk/det/74558/Re... - alternatively, Sunday will be quieter, but still the same wonderful exhibitors - www.computinghistory.org.uk/det/74909/re... - see you all next weekend!

Next week many of us will all be at CFCH in Cambridge, looking forwards to seeing lots of you there. Apparently however they are almost out of tickets, so if you don't have one yet and you fancy going it might be a good to buy one.

eBay isn't always bad. I won a 24-port 10baseT hub (with BNC and AUI ports!!) from user dominio11 and for £6 in shipping costs I got the hub's original box, wrapped in many square metres of bubble wrap, wrapped in a tough outer corrugated cardboard box, and then an awful lot of parcel tape.

I see the Debian mailing list hasn’t progressed beyond: taking past each other, taking issue with things they imagined the other person has said, and generally being terrified that Rust signals the end of days.

The Raspberry Pi 500+ has a network-enabled OS flashing tool built into ROM (or at least the ROM can get on the network, download it and then boot it). This is very useful and all computers should have it. It even flashes as it downloads, to save time.

Fascinating to hear the early history of the Acorn RISC Machine from the key players (but note, not “the” designer - Sophie insists the instruction set was co-designed by her and Steve Furber together)

Bought a new (old) hard disk off eBay. A proper spinning platters IDE drive.
It was shipped wrapped in a plastic bag. That’s it. No ESD bag. No padding of any kind. Just in a plastic bag, with an address label.
What is wrong with people?

Espressif hired a bunch of Rust devs years ago and they have been quietly doing great work supporting Rust on their chips ever since. Still haven’t seen any other chip companies get close.
