> unless you want to waste most of your FPGA on a soft core Huh? As an exercise in FPGA stuff, I decided to use PicoRV32 on a small MAX10 8k FPGA. The core itself consumes easily under a quarter of the logic blocks.

I live in a landlocked country and nearly everyone I know can swim. People usually swim in public pools, lakes or ponds. Swimming is also very often part of the PE middle school curriculum here.

> probably don't even know how to swim I find it surprising that clearly sport-oriented children from a fairly popular tourist beach destination don't know how to swim.

It has been a while since I read the standard, but this seems well into the realm of undefined behavior, not implementation defined.

I now wonder if there are any psychoactives produced by bacteria. Or how hard would it be to transfer some metabolic pathway to get drug-producing bacteria (DMT biosynthesis seems pretty simple, just two proteins...).

Depending on your classification of "startup", there is a massive amount of (illegal, of course) drug distributors using blockchain-based cryptocurrencies to conduct their business.

Moodle is also that piece of software which allows teachers to include arbitrary javascript in the course content, allowing them to XSS themselves to an admin role.

Or use whatever tools are included in their language for safely evaluating strings (like ast.literal_eval in Python).

> random amount of heat Random noise would just mean that you have to take multiple measurements and average them. Depending on the system in question, "multiple" may or may not be impractically many.

That would make sense - the previous slides talk about adulteration/faking the "olive" part, which had me confused.

Heh, I never realized doubles can fit a googol. I knew they work up to 1e300-ish, but never made this explicit connection.

Maybe suggest using polynomials instead of neural networks next time that happens? :)

Yeah - the best Stratix 10 can do 9.2 TFLOPs. A GTX 1080 Ti can do 11.3 TFLOPs. Now I can't find any price info on those Stratixes, but given how expensive these FPGAs generally get, I highly doubt it will be anywhere near the $700 for

> They cannot compete with GPUs on flops with Xeon, but an embedded FPGA might get them closer. FPGAs aren't known for their FLOPs though. Sure, the high end ones pack a punch, but compared to GPUs are still extremely expensive.

That's extremely non-selective - for instance [1] is a random paper discussing ethanol interacting with the 5-HT2A receptors (at least if you are a male rat that is). It would likely also lead to unforeseen consequences. For example, t

Another cool Python DP hack is using @functools.lru_cache to perform the memoization (beware of the maxsize parameter though).

If you are seriously interested in using 500$ chip in any "interesting" volume, shelling out 5k$ for a dev board is nothing you would care about.
