Cannot recommend this enough. I was intrigued at first while watching the movie "Broken Flowers" where this music was subliminal yet haunting (and perhaps the most memorable thing out of that movie!). "Yegelle Tezeta" (Mulatu Astatke from Éthiopiques, Vol. 4: Ethio Jazz & Musique Instrumentale - the entire album is awesome).

I mean if you are a professor and knowledgeable in how the startup uses the data, it’s hardly justifiable that “oh crap i didn’t know they were using it for illegal purposes”.

They were totally complicit allegedly.

Hola, how would the bandwidth limit work within the tailnet if I am accessing it from outside my home network? Wouldn't it incur some bandwidth on Tailscale's end?

I wonder if the DERPy-stuff helps remove most of the bandwidth concerns - thinking out loud...

And the entire works of Church and Turing…

Narrator: It's at this point Michael realized the futility of C++ and promptly learned Rust over a couple of beers pondering if he will ever survive the oncoming AI apocalypse.

Or better yet call a spade a spade: It was programmed to infer…

‘It’ doesn’t need anthropomorphizing in the slightest. It’s a computer program that can slurp up data.

There needs to be a new PL word for languages that work side-by-side (SxS?) with a legacy language. Not to replace it but coexist peacefully. TypeScript, Kotlin, Swift and even C++ are all great examples of SxS languages.

Carbon could be a great SxS language with enough inertia building up over time: still never aim to replace C++ (a fool’s errand) but always work in conjunction with large C++ codebases.

It’s such a great pleasure to write things in TS while always being able to use mix-match JS libraries and tooling and debugging. I hope Carbon achieves a similar result moving the industry and engineers forward without resorting to “languages are religions” tediousness.

In particular if you claim that r2 can be used to store and retrieve any blobs of data regardless of content type but that is only via the public bucket urls and not via workers etc it results in a complicated mess where you get pulled in to a service that over promises and under delivers (or worse, start treating your paying customers like hostile entities).

Worrying part is the account could get banned. Could you reply here if that’s true? Would that take down dns/registrar etc functionality? Google does this and people would move to cloudflare thinking you wouldn’t do this account ban but nowhere is it stated.

Not at all familiar with biochemistry but octopuses are aliens on earth with very different evolutionary track having developed ‘brains’ before our ancestors did independently! It’s crazy we don’t study things like cephalopods like we do SETI etc…

It’s cute that they anonymized the “data science professor”’s name. This person knowingly participated in this alleged fraud which should put their ethics and their reputation into question.

To top it off, this person was later offered a “deal” to be hired into their alleged fraud business once it was merged.

Too damn cute.

What would it take to store/feedback the gained (converted) energy to power the lasers? Sort of like a bootstrap with a very inefficient source of power, and over time transition to the produced clean energy?

Armchair scientisting aside, this news seems like the most exciting news over the past few years - a great way to end this year (/pandemic). We are far out from a production-ready thingy, but if it took decades for brilliant scientists to conjure up this initial clunky toy thingy, I am sure an army of scientists/companies would work at building the real thing much, much faster: we had only a freaking 8086 not 30 years ago!!

We have the basic blueprint from government funded research no less.

This sounds even better. I was imagining a similar idea where for every point in the Bezier you have a normal that can extend both directions by a specified amount. The smoothness still requires some interpolation which shouldn’t be too further from normal Bezier interpolation.

Thoughtful and insightful answer. Although I am on the other side of your argument.

I like your rationale around other cloud providers’ virtualization solutions.

I think the main comparison that’s lacking is one of v8 isolates vs strict site isolation which runs on separate processes. Why would the Chrome team build such a complex thing if v8 isolates passed rigorous security standards/bar etc? This would be good to get your insights on.

What’s the actual cost of separate processes vs v8 isolate? In terms of cpu/memory/latency mainly. I would guess either would win over other virtualization techniques but between the two is it really that stark of a difference?

I am more and more convinced you may have seen the light shine through and people such as me are missing the big picture: so providing answers for this line of attack would be more helpful than comparing with other virtualization mechanisms.

Isn’t this concept originally from C#? (Where interning is the default behavior)

As you scale up with R2, D3, Email Workers etc, is it possible that the _future_ scale of touching very sensitive, "ought-to-be-secure / separate" data / code help reconsider this decision?

Without process isolation, all it takes is one bad Chromium commit or a incorrectly allow-listed JS/V8 command for this model to fall through regardless of how thorough the defense-in-depth/vetted Workers may be.

"the public clouds that run arbitrary native code in hardware VMs." -> Isn't it double whammy then that a V8 isolate + HW attack surface in combination could provide an order of magnitude more hackability?

"Last I heard there were still some lower-powered Android phones where the overhead was too high" -> I believe a Zygote-process fork was made available to Chromium at some point (https://chromium.googlesource.com/chromium/src/+/HEAD/docs/l... ?).

Great, yep, that is good to know.

Second this, his talks are very elaborate, has great pointers to reading material/coursework - as if you were sitting alongside the students in UCL. Very involved though - if you have a 'day job'.

Thank you for doing this!

I haven't looked deeply enough, but does this course use a higher-level 'package' such as OpenAI Gym or teach at a lower-level? (Is lower-level stuff even possible...)

Undergrad? I thought she was some Staff SWE in an OSS company. Seriously impressive, and ought to give anyone imposter syndrome.

Are there any VR headsets with actual curved displays that closely track the curvature of the eyeball?

Similar to curved monitors…

I am always wary when there is a guaranteed return even if it’s a very safe investment. But given the stability of the US Govt, could someone explain who is on the “other side” that provides these returns and why? Possibly ELI5 sorry!

This is good.

Now states are combating such hesitancy by drawing lottery for vaccinated folks.

Like, having this magic, absolutely mind boggling potion that prevents serious illness and death *isn't* already the lottery win of our lifetime??

People in India and elsewhere are dying because of lack of vaccines and here we have educated, first world countries struggle to get their citizens vaccinated.

Unfortunately shaming such people will only push them further into antivax territory.

A dumb but serious question: what powers does a board of directors have? In terms of day to day operations, engineering, product, marketing and so on?

That's really cool. Thank you.

The author does a good job explaining some benefits of an immediate mode renderer but vastly misses the disadvantages.

The immediate mode renderer is great for toy programs. Similar to how you could reproduce 'look here is how simple it is to write hello world and compute the millionth digit of PI' in a new esoteric language...

Occlusion, hit-testing, state changes, scrolling/animations even in the simplest forms will fall over. Infact, that's why we have every major browser move their touch and animation systems into a layer based compositor system (into a separate thread / process).

The author also grossly misses their own example of 'how a spreadsheet with many rows and columns will update faster using ImgUI' and how Instagram styled apps will fare better ImgUi.

A retained mode renderer will use virtual scrollers, efficient culling of nodes for both display and hit-testing (scale to billions of virtual cells) and more importantly help a team of people coordinate their work and get things done.

We are no longer in the 90s.

Reminds me of the Norm MacDonald joke: "When I was a child, they told me to crush the cans, recycle and plant trees. It's for your own future.

Then I grew up and 'here I am', and they said, 'not you, it's for the future generation'.

I know a pyramid scheme when I see one."

I get giddy thinking about The Wire. It's awesome to say the least. Gave me a new perspective of America.
