Comment Radios? (Score 1) 26

II had not heared of that program. erroneously thought that a program so named would have something to do with radios.

I've released some radio related things on github.

Necfull: Because NEC the antenna element solver from the Us governement costs money. This is better and free.
YagiYagi: A much quicker antenna design program with pre-baked antenna models for common antenna types.
Morsey: To learn Morse code with several different learning models (because I learned some things from my wife with the education PhD).
Hamchannel: An OFDM+LDPC packet data link over FM radio program with support for file transfer and live chat. Meets US amature licensed band rules.
remez: An FIR and IIR digital filter design tool that generates C, System Verilog and VHDL implementation code.

I prefer a PoE hat and PXE booting. I have about 14 of them doing different jobs all booting and running from a NAS. Makes remote updates easy too.

That sounds like a fine solution for a working network situation. My needs are more in line with putting Pis in places the network is spotty and I need them to survive for a while on battery and restart from local storage and keep on doing the thing when power is lost for too long. So a UPS hat and NVME seems to do the trick.

> random number generators replaced by domestic designs.

Do you have any information on that? Like which domestic designs? Is there a link?

I've designed the RNGs in several chips including the RdRand/RdSeed one in Intel CPUs. The AMD one was a bit weird but I have no information on it. In my current role we sell a couple of RNG silicon IPs to whoever wants one (a big fast one and a small slow one) and I've left behind a trail of RNGs in other places.

A thing I've noticed is that a number of the RNG IPs out there are not great, but they are for sale and people buy them, including national bodies looking for their own national secure silicon designs, but they're getting the RNG from a chop shop in Bangalore, except for India who's getting theirs from outside India.

Ask Slashdot: What are the Costs of Switching Between Windows, MacOS, and Chrome? 66

UI changes, lost productivity, untransferrable knowledge... Long-time Slashdot reader theodp notes the folly of switching to an unfamiliar new environment to be "more productive"... Champions of the switch often insist workers will be able to hit the ground running and get the same or even more work done from the get-go in the new unfamiliar environment because it's 'more productive', a conclusion often shaped by conventional wisdom or their 'gut' feeling. Decision makers may also mistake their own 'light-user experience' for universal experience and believe all platforms are fungible.

And while it's one thing for a business to delay their delivery dates and increase costs of by introducing a switch in computing environments that's of unquantified and possibly dubious value, how about when a switch in computing environments is made that affects schoolchildren's ability to learn for a period of time?

While a MacBook Neo is indeed cute, what might be the possible consequences of a decision to move 25,000 students off Windows and onto MacBook Neos...? Or even the impact on a single kid who moves from a MacBook school to a Windows or Chrome school (or whose home computing environment isn't aligned with their school). Or students whose teachers decide learning in their classrooms should now additionally require an understanding of the Minecraft computing platform/UI (used in over 40,000 school systems.). Learning Management Systems and now various AI Edtech tools used by schoolkids are also subject to change.

"Even if students and schools eventually benefit from a new platform, one wonders how much learning is lost during the switch," theodp asks, "and what the financial and educational ROI and payback period look like." Are there bigger problems than we realize? Share your own thoughts and experiences in the comments.
