If the purpose of the AD was to do something simply for standard ML workflows, the current AD tools are not the right design for that. They are too complex and solve a harder problem than they would need to. A better approach would be to use the abstract interpretation afforded by Symbolics.jl, mixed with the array symbolics, and use MetaTheory.jl to define simplification rules similar to XLA. You'd essentially get a slightly expanded Jax/TensorFlow with graph simplification rules that could be adjusted/improved directly from the host language. There's a prototype (ReversePropogation.jl), but it needs array support to actually be useful for this application. Or if you don't need the whole stack to be modifiable from Julia, a better interpreter on XLA.jl would get you there. A sufficiently decent lone coder could get those up and optimized fairly quickly for standard ML applications, if that's the goal.

Diffractor.jl has a much loftier goal: optimized differentiable programming of any code from any package in the Julia ecosystem. Because it's building typed IR, it will need a full set of Julia-based analysis tools (escape analysis, loop-invariant code motion, etc.) to approach the amount of optimization XLA can do when XLA optimizations are applicable. While such passes are being developed (for example, this is the PR for putting immutable array optimizations into the language so that Diffractor-friendly immutable can generate the optimized mutable form: https://github.com/JuliaLang/julia/pull/42465), it's at least a few years away before it's doing something like reliably combining multiple matrix-vector products into a matrix-matrix BLAS3 call. That would put it on even footing today to compete against PyTorch in a kernel vs kernel optimization battle, but not against TensorFlow code in cases where XLA optimizations are doing something more.

"Just wait 3 years and it will be really cool" is not a good way to start building a robust community, instead those interested in it need to ask how to demonstrate the improvements afforded by the added generality today. That's why what's making the project tick right now is the ARPA-E projects for physics-informed neural networks, the DJ4Earth project to do direct differentiation of the CLIMA climate model without changing any of the model code (https://dj4earth.github.io/), etc. Those kinds of projects are what is keeping a lot of the dev team open to be full time on these AD and compiler optimization projects. But if successful, it will also give an AD that is great for standard ML.
NFTs are the least sketchy part of whatever is happening here, and that's saying something.
Yeah I think for some folks the dopamine kick of LSD is akin to combining meth with mushrooms. It can be very edgy and electric, with more paranoia and a harsher come down. Mushrooms have always just worked for me. Then again I don't mind the body load(i.e. feeling like I need to take a shit for 6 hours, mild stomach unease, fatigue). I've had some good times on LSD, but it leaves me raw after, sometimes for months. I've done high dose shrooms every week or so for extended periods and while I get a little scatterbrained after a while I don't feel like I'm going insane.

To each their own.
Yeah this sounds to me like a lot of "whatabout"ing.

"I can't drive anything that does less then 3s 0-60s because <insert some flimsy reason>". If you want a fast car, just come out and say it. Driving a high performance car can be exhilarating - I have a second/weekend fast car for precisely the reason that I enjoy it, but I don't pretend it is required or that it is particularly responsible or socially acceptable to boot it away from the lights or go accelerate like shit off of a stick when merging with faster traffic. My hybrid does 99% of my driving, and the other is strictly a weekend guilty pleasure. I've never been in a situation in normal driving where the hybrid couldn't do something my weekend car would have handled (apart from just blow someone off at the lights if they have pissed me off)

The arguments here against PHEVs and EVs etc used to be towing speed boats up mountains every week (it was never made clear why people were taking speed boats up a mountain so frequently! Surely there is not much water up a mountain...)

I guess people need new arguments now that range and towing and charging are solved issues for 99% of people's needs.

I am sure someone will now reply about their journey out to meet their parents in the country with no chargers on the journey there etc etc... Did you try driving your speedboat there instead? :)

Ask HN: What are your new years resolutions?
Im hoping to teach 50 people to learn to code this year and help them get a job in the tech industry.
I think so. My memory fails me (this was 6 or 7 years ago and I’m getting the the bottom of the bottle here), it might have had something to do with the padding in the tables themselves so that they were easier to read. The specific use case was getting recipe ingredients and their quantities presented nicely so they were clear and easy to read at a glance. I wanted to do them all in markdown and export to PDF with a bash script, but in the end, I used plain text and judicious application of white space for maximum portability.

They might have it now, at the time I was shocked the dev refused to even consider inclusion of the feature, even if a patch was submitted (from what I remember).
I'm not talking about stoves, I'm talking about your claim that "the need to deliver gas to anything other than a grid scale powerplant is over."

It's just not true.

That’s a pretty impressive rewriting of history! Ho Chi Minh admired the US then shortly after taking power his government exacted brutal land reforms even the hardliners had to call out as “going too far”.

You’re doing an awful lot of hand waving to explain why Vietnam still doesn’t enact the freedom “they admire so much”. Your claim that Ho Chi Minh’s “disappointment from lack of US support” is the reason why Vietnamese still don’t have those rights rings pretty hollow.
Yes, though this isn't forwarding. The mail is actively being delivered into gmail, who must be programmed to accept mail for that domain.

Forwarding, on the other hand, made it possible to do a simple redirect of one address to another (eg. ~/.forward) but strict SPF rules will deny the forwarder as a valid source for the mails.
> If you go the route of using an (A)GPL core, make sure all 3rd party contributions are made under the terms of your CLA, or otherwise reject them.

If someone goes down this route, does the rejection have to be automatic? Does looking at a pull request without a CLA "taint" me in a way that I cannot implement it again? I am asking partly because I am curious and partly because I remember Drew DeVault (sircmpwn) used to have a big scary warning saying if I have looked at the official minecraft code, I should not contribute to truecraft (now archived I believe).

These are things I never worry about at work. I can look at stack overflow and copy x.filter(x => x.blabla...) and change the bla bla until my javascript works (I don't use filter every day so it is difficult to remember this syntax in my head).

Thank you in advance.

> That simply is not what AlphaFold (or any homology modeling) is doing

Ha! The reality is we have very little idea of about what any neural net AI is doing. Not no idea as provided the raw material these things build themselves out of, but then we throw billions of training points at it with the desired results, and a vast stew of polynomials begins to self organise into something that produces the results.

How those polynomials do it? We certainly don't know from first principles. If we alter compression in a car engine, or moderators in a nuclear reactor, or tension in prestressed concrete beam and an engineer will be able to make a fair stab at the result. Ask the people who built these vats of self organising what happens if they change the polynomials coefficients - and they will have no idea, whatsoever.

Any claim you know what AlphaFold "is doing" is simply fanciful. We've crossed Aruthor C Clark's threshold of "Any sufficiently advanced technology is indistinguishable from magic". It seemed so reasonable when he said it. What he, and we didn't foresee is how it would look if you were the ones who built the technology. "I've build a machine so complex I don't know how it works" crosses a line even SciFi authors had trouble imagining. And now we are confronting it as as our new reality.

I wonder if the all the comments on HN about how AI's don't really understand the subject, or don't fit some definition of "conscious", or can't really "think" are just a form a self denial. It really doesn't matter people. The reality is the only way people could tell it was GPT-3 posting to reddit wasn't because of any of those things. It was because no human could churn out so much error free high quality text indistinguishable from what a human would produce in such a short time.

To claim Ho Chi Minh or Castro would have been freedom loving leaders is laughable.
Why, because it's Electron? I thought the anti-Electron stance had been debunked a while ago, that it's not every Electron app that chews up RAM like crazy, etc.

Electron seems like a great way to get a cross-platform app out there without having to hire three separate departments of code developers.

> Norway has been almost all-in on electric for a good while now.

According to a quick Google search: "The current population of Norway is 5,483,767 as of Friday, December 24, 2021" and NY state is estimated at 20.2 million as of April 2020, and New York City at 8.8 million. It seems you appreciate that Norway is a special scenario. It seems silly to assume something that works there would work in a country that has single cities with larger populations, and states with around four times the population of your entire country.
Why do you need to accelerate so much if the traffic is so slow?

Perhaps this is a cultural thing, but bad traffic here means stationary or less than walking speed. There is no need for hot rod acceleration in these situations!
Well the other one would be forced sterilizations but that doesn’t sound a lot better.

want to team up?

I have a plan to buy land, on that land we add like 5 to 10 glamping spots, one of which is a yurt for us to live in temporarily.

we Airbnb the spots... to pay for building supplies and other things... maybe earn some income too...

we create a big building that is a warehouse basically for common goods that households really don't need to own .. like tools, cleaning supplies, recreational vehicles, etc... the rec vehicles we can also rent to Airbnb's... the idea is every house needs tons of extra space to duplicate things like drills and saws... when you might use those things once a month or year or decade....

if you could just walk down the street and check out some tool... like a library... then maybe we have 3 drills per ten families or whatever we deem necessary to ensure needs are met...

the warehouse could have a commercial kitchen too for community meals etc or people could reserve it for special occasions...

we then could build cheap housing using containers (easier but a little more costly), or earth bags (very difficult work but affordable... also takes longer) then maybe we charge like 200 per month rent per family member, and if we could duplicate this we could create a share system so people could stay at the Zion Utah one when traveling for free, or Disney land... etc...

there might be an opportunity there to also help intentional communities set up glamping camps that maybe keep 50 percent vacancies so it's like a free travel network or plan for residents to travel cheaper so everyone can afford to have more and better experiences via vacations instead of focusing on things and owning more crap we don't need....
Thank you so much,

And just a quick aside, Thanks to Ken for what he does, obviously I ravishly read everything he does!
Oh sure, he had a lot of support. But it was entirely clear the North was not going to allow any free vote. They had already purged any opposition long ago.

So are you arguing that South Korea is a “completely artificial, incompetent and repressive” country? It was also a dictatorship after the war for about 20 years. But Vietnam still is today after 50.
Hi Ben,

I hope you don't find this inappropriate (apologies in advance if you do).

My son was diagnosed with ASD a couple of years back. More recently, it was suggested that he likely has ADHD too. Essentially, the school he'll be starting at next year wanted him to have a cognitive assessment and it came back with a gulf between the things he's good at (reason, logic etc - top 2%) and the things he's not so good at (working memory etc, bottom 7%). Nothing in between.

I had always suspected that I had ADHD, but it was dismissed by therapists who wanted to focus on SAD (very limited success). It felt a little self-involved, but like a lot of newish parents, this was the push I needed to ask for an assessment for myself. The specialist said it was clear as day and at 36yo Vyvanse was immediately (and remains) life changing :)

I'm getting to the question (sorry) - my GP, wife and my a few others suspect that I'm autistic too. Having done a few quick quizzes, it seems that they might be correct (explains a lot, TBH). I was told that there's limited benefit in being diagnosed as an adult though, so I've left it alone. I'm left wondering if that gels with yourself or anyone else that was diagnosed in adulthood? Have you found diagnosis to be beneficial? If it wasn't so expensive, I'd probably do it for curiosity's sake...

Thanks!!
Most people use Telegram for its superior set of features and convenience. The fact that everything is stored on the server-side actually works in favour of its user base by giving them a functionality many desperately need - that of accessing all chats and records ubiquitously, from wherever you want, at any time, from any device. The ability to make channels and groups of thousands of people only works into making it a pseudo-social-media super-app that appeals even more to its users. Besides, it allows you to remain anonymous on its platform despite requiring a phone number for registration.

I have seen so many people going through the horror of losing everything on WhatsApp whenever they switch phone platforms - the chat backups it creates are not transferable across Android and iOS for some reason and there is no way to recover your conversations at all in such a case. Telegram covers many things where its alternatives fall short, but privacy and security are not one of them.
That's about a decade before he was diagnosed with glioblastoma. It wouldn't be surprising if he already had an astrocytoma at that point, but was unaware of the subtle effects which his brain was beginning to compensate for.

That's the bitch about a brain tumor. Your mind is really good at working around it, until it isn't, and then you can't see straight or some other symptom which appears suddenly.

I don't mean to completely diminish your point. Psychedelics can hit you in unpredictable ways, even when you have experience.
> But this all falls apart near and below freezing temperatures.

That's a concern for designs with air-based heat exchangers, but for environments where this is expected to be a problem you can instead exchange heat via pipes into the earth, where it remains a more-or-less constant 50F/10C year-round. Pump heat out of the earth in winter, pump it back in in the summer.
A gas stove is very close to 100% efficient at converting gas to heat. It is certainly not 100% efficient at putting that heat into the pot. Gas produces heat by combusting with oxygen and essentially generating hot air. The air will impart some of its heat to the pot. A ton of the heat will end up just heating the air around the stove (or being dumped outside if you’re running a hood vent).

This article claims 40% efficiency and provides a citation, for what it’s worth. https://www.greenbuildingadvisor.com/article/efficient-cooki...

It’s worth noting that natural gas transmission can’t be 100% efficient either. I don’t know what the loss is but it certainly takes energy to push natural gas through pipelines and there is loss in the system due to leaks.
If the article's glorification of the man is acceptable, then so is criticism. And the fact that the term "cancel culture" is applied to a person that has been dead for more than half a century tells you that the term has become even more useless than it ever was.
The main thing that’s different in ruby is the support for and widespread use of metaprogramming.

I’d suggest using metaprogramming (define_method, instance_variable_send, instance_eval, send) to implement a toy ruby-in-ruby DSL is the fastest way to figure out what different.
>Interesting point. 100 years ago “idiot” and “mental retardation” were medical diagnoses.

> Instead of actually providing a real technical support team.

Apparently you've never used their tech support team. It is by far one of, if not the best, technical support teams I've ever dealt with. Not only technical knowledge but dealing with customers, providing help above and beyond the actual question in front of their face, etc. The only other technical support team that has impressed me this much is Kraken's.

Yes, I have to pay for that support. I also pay for tech support for other things: my automobile ("What's wrong with my flugelmesserbeano?"), for my medical conditions ("Is it safe to take these two medications together?"), for my house exterior ("If I don't fix that drainage problem what could happen in five years?"), for my house interior ("How should I Remodel the kitchen to fit my lifestyle?"), etc.
Because if you rate 1 star that is going to their annual performance, it is very stressful job to work at aws support, in an year you would have to be get 4.8 overall rating which is very hard to get because for the most part customers doesn't rate when they had good experience.
I was in China for about a month, up until a couple weeks before the covid outbreak started. The internet was so locked down I could hardly do anything. Thankfully I had set up my laptop and home server with Wireguard, so I was able to route everything through my home server back in the US. Interestingly, the factory I was in had a room with a "special" connection to the internet, which apparently wasn't nearly as locked down (but probably monitored heavily). This was so they could do things like video calls with businesses outside the country. I don't know if this is representative of China in general, but it was certainly oppressive.
Those aren't exactly the locations that come to mind when you think of "luxury housing". I mean, I don't think people are living in those houses by choice, do you?

Steel and concrete are ugly and cold. Wood is warm. Even brick and stone are more humane.

I suspect this is going to become a highly sought after skill. A well-developed intuition for folding is going to become incredibly important for all sorts of engineering problems. For example, someone like Verity may well be able to help improve the design of an unfurling space telescope[1] by using far fewer [redundant sets of] servos.

Maybe.

A typical 2500W electric burner is equivalent to about 8,500 BTU/hr.

The biggest gas burner on my decent Samsung range is 22,000 BTU/hr.

A high end wok jet ring burner typically found in restaurants (or in some people's homes who like to stir fry) can reach 160,000 BTU/hr.

You can't really get wok hei (https://en.wikipedia.org/wiki/Wok#Wok_hei) without that amount of heat and proper preparation & cooking technique.
I'm in Minnesota. True air source heat pumps aren't great at such temps, but ground source heat pumps it doesn't matter at all. Lot higher install cost though.

surprised, but at the same time not surprised. Something like the radio would be a logical piece to make trivially replaceable.

It didn’t take a genius to see that 3g would be gone in far less time that the car is expected to operate. More stupid was cars built after LTE, etc not supporting those technologies already.

But then car manufacturers are known for cutting costs regardless of long term impact.
The traditional method for cooking a stir fry is in a wok and at a very high temperature. Induction doesn’t get hot enough, and it’s not possible to heat a wok on one anyway. You can make a stir fry in a pan, and at a lower temperature, but it’s going to taste completely different.
Economies of scale make energy distribution more efficient as you scale population not less. New York City could for example use a relatively shallow bore hole to gather geothermal energy and get “low grade” heat (50-100C) for district heating where such systems don’t really work for single family homes.
Context is key. It was quite obvious from the original post wanting to own shares specifically for what that would entitle them. Following that up with "don't you mean short it?" shows that the original point of the post was not understood. However, if you forget the above and focus on the one post, you lose site of the conversation.
Perhaps they mean continuous or differentiable functions (evident by the desire to put an order on the elements)
