> Double descent with overparameterization is exhibited in "classical settings" too and mentioned in older books. I’m curious for references or citations to this. When I was going …

Extraordinary claims require extraordinary evidence. This evidence seems weak at best. I want to be charitable, but hard to imagine this is anything other than an incredible stretc…

When do you think we will get an update to C11 or more recent version of C to MISRA? Do you all have any influence on "Safety Critical C" standards?

I'm curious if this is a (temporary, unsecure) way to use google if you're in a place that google is currently blocked. Small chance, but in case anyone on HN is in a place google …

> Because threads are so sensitive to initial conditions, it ends up skewing an entire discussion. I haven't thought about this before on HN, but it makes a lot of sense. I'm curio…

At the top of the article are two open source repo links: Environment Generation: https://github.com/openai/multi-agent-emergence-environments Worldgen: https://github.com/openai/m…

What other pigments show up in lymph nodes? Hair dyes?

Cool! I did this a while ago for some CPU-bound stuff, and ran into a bunch of performance bottlenecks. Some things that helped me scale ptrace-interception up: - SECCOMP_BPF filte…

Is this paper published yet? The `Article` link doesn't go anywhere, and Google Scholar doesn't know where to find a copy.

Also recommend this as a follow-on. I think it's an important point, and also well presented. The anecdotes make it memorable but it's concise where it matters. After I read this l…

That article is about the FDA and a melanoma drug. I don't think it has anything to do with Cray or patents. Possibly mis-copied link?

Congrats! Is there a short summary about how your approach is different from existing stacks (like tensorflow, or nnvm)?

It looks like nvidia GPUs treat denormals as zeros for single-precision floating point math: http://developer.download.nvidia.com/assets/cuda/files/NVIDI... (sections 4.1 and 4.2)

Syscall interception works for _every_ program, it's just a matter of doing it correctly. VDSO is a small set of (3) calls which are not syscalls but direct calls (for speed/effici…

This depends on the virtual machine or container! Ironically, because the folks working on containers/VMs are _really_ good at what they do, time access calls in particular have be…

Libfaketime is great, especially if you have a good idea what time calls your target process is using. If they're inspecting EHDR and calling VDSO directly, though, or they've stat…

Nice Implementation! I built something similar a while ago to warp time in video games (for training reinforcement learning agents). Some issues off the top of my head (that I ran …

Good intuitions. FCC regulations restrict EIRP[0], which is essentially "what is the signal strength in the strongest direction". It's possible that increasing directionality of yo…

It looks like we're moving towards a solution (in a slow, jerky, shambling way) with replacing hardcoded boardfiles with device trees. If RISC-V does this well out of the gate (lik…

Followed the original RepRap project as a college student. A bunch of us students tried to do a group build of the RepRap Huxleys. It was way too much work to try off the bat in or…

Also, the creators have been working on a short made-for-youtube cartoon show (~5 minute episodes) called "Bravest Warriors". If anyone here likes Adventure Time, check it out: htt…
