I love that these legacy adaptor projects exist, even if I don't have a personal need for them.

Open-source hardware USB to GPIB adapter connects legacy GPIB/IEEE-488 instruments to modern hosts
XyphroLabs's UsbGpib is an open-source hardware, inexpensive, and portable USB to GPIB adapter aiming to provide "access to legacy GPIB/IEEE-488 instruments using contemporary hardware and software, with a focus on accessibility, openness, and ease of integration into current workflows". Initially developed by Hewlett-Packard in the late 1960s/early 1970s, GPIB (General Purpose Interface Bus), also known as IEEE-488 or initially HP-IB (Hewlett-Packard Interface Bus), is a short-range digital co…

my definition of "an UI bug" is basically "any design or implementation choice that makes users miserable". i do not think many in open source hardware|software share this definition and i won't be satisfied until it's a new norm

My general experience from looking at a lot of RTL between work and open hardware stuff is that ASIC people seem to be more heavy users of advanced systemverilog features (structs, interfaces, etc) than FPGA people.
I know a lot of FPGA tools historically didn't have great support for these things but unless you're still using ISE or Vivado 2017 there's no excuse.
Anyone else see this trend too?

Will we see you tomorrow at Tech Pizza Monday? VICTORY CAFE whoops, that was too loud, Victory Cafe, 440 Bloor St. W., 6 PM. With any luck, we will have some printouts of the paper we will discuss at on tje following Monday. Come for the pizza, also, stay for the pizza, not to mention the discussions about free and open technology for a free and open society. #Toronto

Keeping the PlayStation 2 Alive: Inside the World of the PCSX2 emulator
For more than two decades PCSX2 has been the go-to PlayStation 2 emulator, letting players revisit one of gaming’s most iconic libraries on modern hardware. What began as a scrappy open-source project has grown into a polished emulator with wide compatibility, powerful upscaling, and a dedicated community of contributors

Preparation of initial states with open and periodic boundary conditions on quantum devices using matrix product states
We present a framework for preparing quantum states from matrix product states (MPS) with open and periodic boundary conditions on quantum devices. The MPS tensors are mapped to unitary gates, which are subsequently decomposed into native gates on quantum hardware. States with periodic boundary conditions (pbc) can be represented efficiently as quantum circuits using ancilla qubits and post-selection after measurement. We derive an exact expression for the success rate of this probabilistic app…

The thing about laptops is that there are plenty of options. Unlike, say, phone OSes or ISPs, there's a million different laptop vendors, all trying to differentiate themselves (despite often using the same factories & hardware).
I can buy a 3yo Latitude on ebay for $250. If I'm going to pay a premium to buy a product that's open and/or upgradable, I'm doing so because I believe in the company's goals, and by extension its morals.

When we downsized we worried about squeezing more bodies into beds when our 2 daughters, son-in-law, and granddaughter come to visit. To solve that issue, we took some open space in the basement and had a Murphy bed installed today. We bought a premium product from a store called Beds Off The Wall in Brampton, Ontario. Great showroom with lots of options that allowed us to customize the cabinet and hardware, with outstanding customer service. The delivery and installation team was also awesome. My wife picked up a couple of folding room dividers so we can create a private space. Pretty happy with the result.

> Cambridge’s preservationists don’t just mount disks and hope for the best; they sample the raw magnetic signal itself. Specialized hardware, such as the KryoFlux and open-hardware Greaseweazle interfaces, captures the flux transitions — the tiny changes in polarity that encode data — and reconstructs the file structure later in software.
