Few observation / opinions from a parent who sent kids to a Russian math school in an area with “good public schools” and kids are now older (HS & college). YMMV. The teachers by and large care about and enjoy math. That is good. I

Ah - I see. Visuals are in the preprint PDF, not the website.

I coudn't find any visual examples on the site - did i miss them? Was hoping to see how the various code examples actually render.

How many people die each year from non-GFCI outlets? Data to back it up?

I know I should run my own ZFS cluster at home. It would make me a better person, it’s the righteous right thing to do. Maybe in my younger days I would have been purer of spirit. Alas, time, kids, other hobbies & commitments have stood

We have gone through a similar journey on a project at work - starting by using Z3 then moving to a simpler in-house built boolean constraint solver. Will see if it is something that could be open sourced.

We talk power, not servers, at work because it’s the limiting resource at any scale. “How many MWatts do you need next year”. Its not that you can’t do these workloads on CPUs or GPUs - you can. But you can do it at 10x-30x less power on

“Pure” does definitely connote that you’ll be able to read all the code in the given language. That’s exactly what “pure” means - “pure rust”, “pure go”, etc. IMO you can’t say the heart of all the work is a c++ lib and call it a “pure JS”

And also some good articles by the CockroachDB folks on vectorization. https://www.cockroachlabs.com/blog/vectorized-hash-joiner/ https://www.cockroachlabs.com/blog/vectorizing-the-merge-joi..

This seems similar, but perhaps less ambitious, than the very well done Nand-To-Tetris ( https://www.nand2tetris.org/ ) - anyone know both? Nand2Tetris has open source simulators, great docs, lectures / help via coursera

And for completeness, here’s another company that I also used at $previous_job that provides a “semantic model” offering. This write up also helps describe where it fits in. (This one has just enough content vs marketing for me not to feel

Quick scan of dbt metrics - looks like it lets you define a flat, single view of a metric with a predefined set of “filters” (Ie sql predicates). Also it only allows a metric to come from a single table; “joins” are a TODO. It is missing th

Well said! We need more of this problem space exposed to engineers and not just for “analysts”. I’ll share a couple other articles from a company that does a nice job explaining the technical problems in what is traditionally “business anal

Cool. Like open source Looker. We adopted Looker at $previous_job. Then they got bought by Google, which was great for us as we were becoming a big GCP customer. I strongly encouraged google / looker team to at least open source their

This is a really accessible write up. Although I agree with the comment elsewhere of asking for a “examples in Rust” comment somewhere to save everyone the 15 sec of squinting “is this … C++, or…” who don’t instantly recognize it. Also funn

Interesting - so more like “verity but verify”. Very cool.

tldr: “scientific” study with N=1 (author / researcher) draws useless conclusions, but because it contains “cats pics” gains some attention.

Basic - naming a capture group. Awk / posix - \1 Perl - $1. Python - (?P<name>). I’d find it hard to ignore the specifics. I mean if you only ever use one tool and were never exposed to other regex engines I guess.

You must not have suffered enough, I mean used regexs widely enough. He meant “syntax” in the sense that different regex engines have different syntax and capabilities - can I do a negative look ahead assertion in engines Z, how do I do a z

The article lists alternatives but doesn’t mention Cython. That’s a miss. I’ve done both. If numba works, it’s great. I found it a bear to install. Cython is more work, did what I needed - allowed me to incrementally type Python to get C co

Making false statements on an visa application form is grounds for pretty much any obvious consequences that follow.

He said he had COVID a second time not long before going to Australia (Dec). Which is truly fortuitous timing - if he didn’t have COVID around then, he couldn’t get into Australia via an exemption for the recently infected. And then video

Sure, perhaps I was inarticulate - he’s a world leading medical researcher who heads up a world leading medical research institution; he is one of the 10 most cited medical researchers in the world. Yadda yadda…

Interesting point I heard about why we don’t (yet) have a vaccine for HIV where we do for COVID - the human body can fight COVID. Ie we mount an immune response and some people survive and recover on their own. This is largely not true with

No one gets a free pass, for sure, but he’s a pretty qualified thinker of things medical and health. So coming here and calling him out on it should probably warrant a bit more than a “uhn uhn”. (Edited - asimpletune above said it more eloq

I think activating “crisis standards of care” is a bit more substantial and worrying than any previous claims of being simply “overwhelmed” which could be subjective. This is what we are seeing here in the US. https://www.google.
