I've been pretty happy on Fastmail as a custom-domain email host the last few years.

Recent OpenBSD should be able to do modern TLS, and probably ACME, which would have been more interesting.

The Dolphin is on display at the Maritime Museum of San Diego.

Not much in space; There's almost no matter to convect!

What does the RF front end look like? I see the Lattice ECP5, but what are you using to go from bits to waves?

Too clever by half

I've never had my ID checked boarding a domestic flight in the US. ID and sometimes boarding pass are checked at the TSA checkpoint before the gates.

Those pages both refer to the security checkpoint, not the gate agent prior to boarding. I've never had my ID checked while boarding domestically in the US.

GPS C/A signals are pretty straightforward to generate and not authenticated.

They don't. Analog low-pass filters don't do linear interpolation between samples.

Reconstruction filters in DACs are analog low-pass filters. They don't do a linear interpolation between samples.

'mindmatters.ai' being associated Discovery Institute, founded entirely to push creationism in US public education, is not a great sign for the credibility of this article.

yeah, most of the kernel maintainers in that thread seem to be against it. bcachefs does seem to also have a non-code-generating implementation of this, as it runs on architectures other than x86-64.

huh, this is fun: https://lore.kernel.org/lkml/ZFrBEsjrfseCUzqV@moria.home.lan...

There's a little x86-64 code generator in bcachefs to generate some sort of btree unpacking code.

I bought my own 3rd party cable modem for Xfinity and it works fine.

It looks like it has MIPI DSI. If you were determined, you could use a DSI->HDMI bridge. AD makes one of those for some reason: https://www.analog.com/media/en/technical-documentation/data...

I don't think running on a bunch of CPU architectures is really unique to NeXT. Windows NT ran/runs on x86, Arm, Alpha, MIPS, Itanium, and PowerPC, all with a desktop as a full-blown product. Forms of desktop Linux will run on all of those and more.

In early 3-slot North American payphones, there literally was a bell that the coins struck and a transducer inside the payphone body.

They weren't based on the same novel -- but the novels "Fail Safe" and "Red Alert" were similar enough, and the release dates of "Fail Safe" and "Dr. Strangelove" were so close that Peter George and Stanley Kubrick sued the author and production of Fail Safe over copyright. In the eventual settlement, Columbia Pictures bought and distributed Fail Safe.

[I'm basing this on a reading of Wikipedia - https://en.wikipedia.org/wiki/Fail_Safe_(1964_film)#Lawsuit ]

This poster's whole submission history is a little bizarre; Three pieces of blogspam from "Thomas Blobaum" and one thing related to the "Nebraska Blackshirts", a part of a US college football team.

Nowadays, mechanization and automation make large-scale nuclear first strikes pretty much pointless. Add to that the improvements in missile defense and the result is a different scenario. If we ever see nuclear weapons used in anger again it will probably take the form of artillery used against armored formations, fleets, and satellites.

I don't think BMD has really improved enough in the last 40 years to make "limited nuclear war" (at least between the US and Russia or maybe China) a real possibility. I also can't find, in my 30 minutes of research, anything supporting the idea that the US/NATO has any small tactical nuclear devices hanging around anymore.

AFAIK, SiFives business is about selling their RISC-V cores and ASIC consulting services. RISC-V is still kind of new as far as hard silicon Linux-capable cores go. My understanding is that this thing is meant to serve as a dev kit for their U74 core and U740 SoC platform, provide hardware for interested-enough Linux kernel devs and distro maintainers, and serve as a real, up-for-sale RISC-V board with a real SoC, 'all the fixins', and no FPGA. That's to say it's not a board for people who'd otherwise buy a RasPI or slightly more expensive SBC -- It's closer to a proof of concept.

For anybody else wanting to do this, you'd be better off picking up a Grandstream 80X ATA. It supports pulse dialing, pulse to tone conversion, 'high power' ringing, and decently modern TLS. If you're good with a soldering iron and have a 3.3v TTL serial cable, you can also pick up really cheap used Vonage HT802s and 'unlock' them.

Stream ciphers can operate without adding any extra delay and are considered plenty strong.

Mike Harrison of mikeselectricstuff gave a talk at the 2016 Hackaday Belgrade conference on how insanely complex these things were.

Want a low-power core for an IOT device? You could license ARM or you could build on a free POWER softcore.

To be fair, there's a bunch of small, decent quality, open source RISC-V cores that have gone to tape-out (RI5CY, Ibex, PicoRV32, SweRV)

It looks like he found that reddit thread.
