Lots of 2-key keyboards exist, and are even for sale inexpensively. https://duckduckgo.com/?q=2+button+keyboard&t=ftsa&iar=image...

Not very convenient for having both buttons near your thumbs, though.

I've been trying out the related SwyftCard for Apple //e on the izapple2 emulator.

https://github.com/ivanizag/izapple2

  ./a2sdl -model swyft

It actually works really well; it uses the left and right alt keys as the open and solid Apple keys, which the SwyftCard uses as forward and backward leaping. It's quite easy and comfortable to use!

That's not enough. Just uBlock Origin's default list "uBlock filters – Ads" already accounts for over 38,000 rules. EasyList is over 87,000!

SolveSpace is how I teach people CAD at my local makerspace. It's the only program I know of that can be properly onboarded in an hour or so, figured out from there, is useful on its own, and that makes for a good stepping stone to Inventor/SolidWorks/OnShape/etc.

QCAD is not a parametric 3D CAD program. You have to know what your part will look like before you draw it, because all it really does is neatly draw lines and curves.

Contrast with Solvespace (or FreeCAD, or any of the popular commercial parametric 3D CAD programs), which lets you specify relationships (constraints) between elements in 2D and 3D. The shape of your part is the finished result, not the starting point.

Java was introduced slightly before the cutoff -- 23 May 1995, so almost exactly 29 years ago. The earliest ancestor of its Swing desktop GUI library, called Internet Foundation Classes, was released 16 December 1996.

These lathes?

It looks to me like they're for hand-finishing (deburring or polishing?) parts. I wonder in what kinds of work that comes up often enough to justify dedicated machines?

Indeed, someone does!

TFA is a scan of a reprint of the original article. The reprint is "The Machinist's Bedside Reader" by Guy Lautard. The missing page is pg. 159.

The Internet Archive has a copy which can be checked out and read for free here:

edit: the book is also currently in print, and can be purchased new on Amazon for $50 https://www.amazon.com/dp/1953439063

The "System Losses" breakdown shows the various additional factors they are derating the system by. The figures seem reasonable enough, and give an additional loss of 14%.

I put in my own address, which is in the 4.0-4.5 kWh/day region, and set the DC system size to 1 kW, which corresponds to 6m2 of panels (courtesy of their rooftop calculator). The NERL website estimated that such a system would yield between 2.45 and 6.48 kWh/day, with an annual mean of 4.71 kWh/day.

That works out pretty close to what the map indicates for my region: 4.5 kWh/m2day * 0.2 conversion factor * 0.86 losses factor * 6 m2 of panels = 4.64 kWh/day

If it ran at full speed, you could run tons of original 6502 software, which almost universally rely on cycle-accurate timing to generate video output.

That's about there not being a charger in the lot that the rental company uses as a matter of course when rentals are returned to them.

Like a taxi or bus?

Copy the link and open it in a new tab. Works fine.

Is that an accurate way of characterizing it? I've understood The Apple Vision to be augmented reality headset, not a virtual reality headset -- that Apple intends it to be used for applications more like HoloLens was envisioned for, rather than what Quest, Index, or PSVR are currently used for.

Unfortunately, it doesn't appear to offer RSS feeds. Still, it looks like it really does let you view tweets and profiles without being logged in, so I may well use this.

Starship must utilize refueling. It can't get to, land on, and return from the moon without it.

It turns out that it takes thought effort to semantically tag/classify everything consistently and completely, so rather than make the decisions, it's easier to just not do it.

It absolutely is DRM, just a different form than media encryption. It's a purely-digital mechanism of enforcing rights.

I'm surprised that so many posts are people saying they want this. I've never felt a strong preference for shady seats while traveling. Why do (many) people prefer them?

Spirit literally calls them "big front seats".

Freescale owned the IP after Motorola, and they've since been acquired by NXP. For now, they are still available in the form of the derivative (simplified) ColdFire processors.

> SpaceX, Blue Origin, etc would really like to see rockets be an alternative to airplanes

Why? Rockets are intrinsically less efficient and less safe than airplanes. Why would they try to compete for use cases where they are at such a disadvantage, and where they have to-date shown no interest in competing with fixed-wing aircraft?

The closest those companies have done to showing interest in pitching rockets against aircraft is Elon Musk saying that his company will offer ultra-high-speed flights via rocket, which is more like a Concorde-killer 25 years after the Concorde got killed by its own costs.

Starship, Blue Origin's upcoming heavy-lift rocket New Glenn, and United Launch Alliance's upcoming heavy-lift rocket Vulcan, are all powered by methane and oxygen.

> Are there no 32-bit CPUs with a simple architecture and easy programming model?

There really aren't. You could consider Arm (maybe with the simplified but 16-bit "thumb" instruction set), or MIPS, or RISC-V. Between all of those, it's rare to find bare CPUs; usually you get them in a system-on-a-chip, with things like DDR memory and other sophisticated peripherals built-in. You need complicated drivers and a bootloader, maybe even with signed payloads. Nothing as architecturally simple as wiring the address and data lines of a CPU into the address and data lines of some RAM or 7800 logic directly wired into a keyboard.

In principle those devices could exist, but as a hobbyist you can only really get your hands on hardware with that kind of conceptual simplicity by either programming it into an FPGA, or by using hardware that dates back to when that approach to computer design was cutting-edge.

edit: you could maybe consider some kinds of microcontrollers? The Parallax Propeller comes to mind.

I don't think a 10 MHz Z80 and 512 KB of RAM is enough for DOOM as we know it. There are some games called "doom" for the similar Ti 83/84 calculators, but they're more similar to Wolfenstein 3D: very cut-down from what DOOM is actually like.

Not the OP you're replying to, but yes, if I choose to open-source my intellectual property, then I definitely expect FAANGs to be able to use it for free. That's what I want when I license my code open-source or public-domain. I'm allowed to give my labor away for free, and I choose to do so.

The Confederacy was never going to win outright, and they knew it. Their goal was to force a stalemate, allowing them to continue to exist as a separate country from the United States.

edit: and for the first few years, it looked like they might be able to do that.

I did not forget Artemis. Artemis 2 will not require Starship; it's just the Orion capsule going around the moon and back. Starship Human Landing System won't be needed until Artemis 3, which is currently scheduled for December 2025. That is a lot of time use to get Starship in shape to operate beyond Earth, and even if it isn't enough, won't result in the cancellation of the Artemis project.
