The Pi ecosystem is coming apart at the seams. Talk about falling off a pedestal. By the time you buy everything you need to make a Pi 5 even remotely usable and reliable today, you'll have spent as much as a small form factor PC. What

This is valueless trash. Everyone here knows it; the author knows it. Products that try to tax ignorance have no place. "Enterprise plan"? Fuck right off.

"Dangerous" and "damaging" and "burning" are purposely selecting awfully strong, even disingenuous, words for whatever is going on; the article only gives evidence that the anodizing dye on a heat spreader has

IMO overhead router is way worse than a table saw, but compared to its usage, the table saw wins by far.

I'll forever remain skeptical of SawStop. I understand their mechanism works quite well and they sell a very high quality saw, but I will never in my life buy it. It's amazing how the discourse online has shifted. SawStop's o

Stumpy Nubs absolutely did once run his hand through a saw; by your ridiculous definition he is absolutely qualified to have an opinion.

If your programs are all unikenels running on a hypervisor, havent you just reinvented a regular operating system with more and stronger abstractions?

I was thinking about this yesterday; other than POSIX why do operating systems choose a filesystem heirarchy as the thing that they provide as a datastore? Why not a structured document store, a blob store, a key value store, or some mixtur

I have tremendous respect for your efforts and goals. I should have reiterated that in my original comment. If you need to price these boards at $350 as a measure to ensure the success of your project, and you have people willing to partici

There’s no “through” a wormhole in the sense that you might immediately assume. The entrances are event horizons just as with a black hole; in fact it may be useful to think of a wormhole as more or less a black hole that appears in more th

The only problem with the wormhole (Kerr metric) travel thing that scifi seems to ignore is that once you go in, the only theoretical path out is to traverse around the end of time and emerge through a white hole into a completely separate

by gorkish 3y ago
This seems as if it could be cool, but the board is $350 with a BoM of about 50 bucks. Considering the current nascent state of things, this doesn't really feel like a project on a successful path.

Thank you very much for the references. These look like great projects and I am happy to see that I’m a bit out of date. The vendors don’t appear to be making anything easier though; it appears these projects are still supporting devices by

Yours is the best response to my comment so far. I very much enjoy the observation that LLM's appear to function optimally when trained on "tokens" and not the pure unfiltered stream of characters. I think I am ultimately att

I'd at least think that quadrature samples would be preferred as they offer instantaneous phase information. I dont think there is anything to be gained by forcing the model to derive this information from the time series data when the

Yeah, except no; the ear works by having cillia that each resonate at different frequencies, differentiated into a log-periodic type response. It is mostly a "frequency domain" mechanism though in the real world the time component

The FPGA he is using has native pcie so usually all you get on this front is an interface to a vendor proprietary ip block. The state of open interfaces in FPGA land is abysmal. I think the best I’ve seen fully open source is a gigabit MAC

For any other DSP people tearing their hair out at the author's liberal terminology, whenever you see "wave" or "waveform" the author is talking about non-quadrature time domain samples. I feel this work would be a

I'm not suggesting that FPGAs are easy to exploit; I'm saying that the premise that they are fundamentally secure and/or the only way to implement this requirement is wrong. Having a hypothetical discussion about how an FPGA

by gorkish 3y ago
That is good! I am hopeful as well! However I don't think that the parts that you are talking about are fundamentally solving the problems I discussed. You have always been able to go to a vendor outside of the top few and get cheaper
233.
by gorkish 3y ago
FPGAs aren't inherently secure. I'd assume that a nation-state-level actor would have the ability to extract the bitstream from an operating FPGA which would invalidate both of your statements if additional protections and securit

> "this fpga could have been an arduino" That's giving a lot of credit! I see way more of "this FPGA could have been two logic chips and an EEPROM"

by gorkish 3y ago
The FPGA in my scope probe that is dutifully implementing the functionality of an EEPROM while loading its configuration from an even larger EEPROM exists in a state of extreme disagreement to your comment. Yeah obviously FPGA's are un

Worrying about the visibility of activity on the Moon from Earth is about the most indolent form of misapplied thinking I can imagine. Absolute useless waste of effort. Get real.

I like the strain gauge application best! I do personally feel that the #1 application of FPGAs is to make short run and high-end hardware fantastically more expensive for business and government (+military) customers. As it has nothing to

I'm just here to remind everyone that doesn't already know that the "full" raspberry pi models are also quite accessible[1] as bare metal platforms today. If you need an MCU with 8GB of ram and 1TB of flash, you can abso
