I guess it depends on the context in which it is applied. It is anecdotal, but in the industries where I worked, people trying to introduce Bayesian statistics did not have a higher chance of their results being interpreted properly. If you do A/B testing and don't do pre-registration or power analysis, what are the chances that you can/will be able to explain the nuances of probabilistic reasoning ?

I agree w/ the parent poster than the fundamental issue is probability: if you are talking w/ people w/o background in stats, you will have a really hard time to go beyond a true/false statement.

Moreover, one of the most effective (in $ terms) application of statistics in recent times is A/B testing. While you can do "Bayesian A/B testing", the basic methodology is fundamentally frequentist. Mistakes there can be hedged through better tooling / UX (to avoid peeking, etc.), as effectively as using Bayesian statistics.
That's right. Most problems don't warrant deep learning with the current state of the art.

Not doing this yet for lack of a Pi 4 (or other SBC with USB 3.0), but I plan to build a simple and reasonably performant NAS with one and USB SSDs.

I've considered PCIe -> SATA adapters, the boards that do this nicely aren't available - Radxa Taco, Wiretrustee SATA board - or have too few slots - PiBox- and the performance gain, about 30%, doesn't seem worth it when accessed via the network anyway. Of course I'd love to be corrected (hey Jeff).
I think the point was that since they banned gas leaf blowers, they might as well have banned all leaf blowers, leaving nothing but hand tools. Of course someone could invent a hand-cranked blower or something... would be interesting to see exactly what loopholes in the legal wording people would find.

Except that you then give two examples of services that have solved this problem. I'm not saying that it's an easy problem, but it's clearly not impossible.
I'm sure it is, but "gluing things together" coherently in response to a text prompt is a stupendous achievement. It's not AGI, but it's miles ahead of where we were even a few years ago and opens the door to automating a class of jobs I don't think anyone back then believed could be automated, short of AGI.
As another spin-off of this, I’ve always wondered how much tidal energy we can extract before we start messing up the moon’s orbit.
How long does it take to develop new challenges with support across all of the languages you have? And how scalable is that process? This looks super cool, and a fun way to spend some of an education stipend (that for me mostly goes unused) but I'm not sure how many times I'd want to re-implement git in additional languages.

At the moment it looks like there's git, redis, docker and sqlite as challenges (that have varying support for different languages) with a regex parser, http server, shell, bittorrent client, and react up as future candidates, if I've read the site correctly.

Ooh, that's nice progress! At TigYog we're actually using Stripe Elements - not Checkout or products - so I think this can't work for us yet. It would be cool if you exposed some of this functionality in Elements. I'm not sure what that would look like though :)
Yes I think Gelman is doing great work, as is e.g. McElreath [1].

The problem that I care about is not whether frequentist statistics can be taught and used well. They can, and I try in my teaching to do so.

The problem is that empirically, frequentist statistics is a fig leaf for a ton of extremely problematic work. And pushing bayesian thinking is currently our best chance to fix this, because it's easier to do a shift in the mental framework than to fix the perception of an existing framework.

Well not all CEOs are so myopic; Andy Grove of Intel was not, for example.

Whether or not a next-quarter focus works, probably depends on the industry. In semiconductors, especially high-performance semiconductors, the R&D on manufacturing this year determines whether the design several years from now is able to be competitive, so there is a need to be more forward looking.

Personally, I would say that not being able to get into my email (or other online services) when I needed to was a MUCH bigger problem than worrying that someone else could somehow reset it in order to take ownership.

You know that thing, you try and get into your tax return and you can't find the username that you only use once per year so you have to wait for them to send you a letter including your username (assuming your address is up to date).

If I read this right, this is still the basic geothermal structure and idea but is really an improvement in drilling?

Geothermal seems to be limited by finding suitable places for it, which is generally where you only need to build fairly shallow wells. Building deep wells is expensive. If you can build deeper wells faster and cheaper then it opens it up to move areas.

Is that correct?

Better and cheaper drilling has way more applications thatn building geothermal wells. I mean we need to build tunnels all the time. Cheaper drilling probably has significant applications for the oil and gas industry too.

So if that's true, why the focus on geothermal? I mean I support research into renewables but it's a whole lot easier if, say, you can get the oil and gas industry to pay for your R&D, effectively.

My understanding is that geothermal energy production is still pretty low.

It's also worth noting that boiling water to steam and turning a turbine has inbuilt costs that you can't escape. There's only one power source that directly creates energy and that's solar. Additionally, solar has no moving parts (other than facing PV pannels towards the Sun, optionally).
Good insight, we've been suggested that using CodeCrafters for onboarding engineers increases your overall talent pool (hire language agnostically, then internally train engineers in your target language).

Carbon Language – Final Conclusions (It's Probably Not for You) [video]
Yep - I've had exactly this experience. In the past I had skunkworks'd a program which became a primary diagnostic tools at the company. It was maintained in an ad-hoc manner and a number of people worked on it over time. A few years later, I was adding a feature and something just wasn't working the way I thought it should. Tracking it down to some lower level networking code, I saw something that was just obviously crazy. Feeling real anger over how some inexperienced engineer had violated my codebase with their incompetence, I pulled up git blame to figure out who was about to get an earful.

And there it was: Me - from 7 years earlier.

I'd like to think this happens to most of us that are around more than a few years.

I don't know why this means sex needs "redefining" when the article itself says it's like 1 in 4500 who are "other"? A really occasional abnormality doesn't mean the classification is wrong. Like, there's some kids born with 1 arm. They're still "human" but we still define the human normal as 2 arms 2 legs.

The 2nd half of this article makes it sound like they're writing this more to push a social agenda than in the pursuit of scientific advancement.

Still an interesting area of study. I wonder if e.g. women with male cells forming neurons are more "male brained" or vice versa.

I simplified my other post for better readability and just realized I made a stupid mistake doing so; I replaced a public per-user salt that's to be queried during login with "normalize(username)". In the given variant it would actually be possible to perform credential stuffing if both use exactly the same hash function and if I use the exact same username. However, if a user-specific (or at least site-specific) public salt is added, this doesn't work anymore. That's what I deserve for writing this by heart instead of putting it into ProVerif first. Maybe that bad simplification caused the misunderstanding?

----- edit, original post. feel free to answer if you still disagree :)

Now we're talking labelling. To me the password is what I, as a human, enter in some login form. What's sent to the server is derived from that. In once case the derivation function is just the identity, in the other case it's a trapdoor permutation (with a public salt). For the authentication flow it's quite similar, yes, and for many kinds of attack I wouldn't care what I have (e.g. PtH on Windows) - but for the user there is a huge difference if they memorize + enter "7110eda4d09e062aa5e4a390b0a572ac0d2c0220" or "1234".

Let me pose a scenario and ask you a question: Assume I'm dumb and my login on HN as well as Steam is archi42 with password s3cr3t. Now the simple "sent password in the clear to the server" allows GabeN [president of Valve/Steam] to log my credentials and post spam on HN. With a trapdoor derivation function that's not possible anymore [this is where I realized my bad simplification].
So if the two are exactly the same thing, why does that attack work in once instance, but not the other?

(edit2: if you answer this, assume that there is a user-specific, public "salt" A that the client queries from the server prior to computing X = hash(A + password))
The article puts a lot of weight on the use of pre-existing technology in a new mode for making deep bore holes, and glosses over the engineering challenges that have yet to be solved ("transmitting a clean beam and having it operate at a high energy density without breakdown").

I'm not equipped to judge how difficult those problems will be to overcome in practice. Obviously this would be very cool if it bears out, but it's hard to tell if it will.
Hi Rötlich, There is no limit on the free trial. And post trial period you've the option to upgrade to monthly tier. You can also pay for early and get 20% off.
With scooters, of course you could argue that a two-stroke-engine scooter is still better than a car that emits more CO2 (and even more if it's stuck in traffic or searching for a parking spot in some European city center). But electric scooters are definitely competitive and noise-free - of course more expensive, but still affordable, at least for an average European income.
That's an interesting argument.

From a business standpoint, yes. However, making unsustainable (and unobtainable) vehicles that people do want, at least keeps the automotive industry alive (for now).

Solar radiation, ultimately (wind heats air, air expands, that creates a pressure differential which ultimately caused wind).

Maybe you‘re thinking of tidal power plants? Tides are gravitationally caused, and as far as I know tapping into them infinitesimally changes Earth‘s rotation (and to some extent probably also Earths and the Moon‘s orbit).

The ease with which you can make oil-based fuels convert chemical energy into mecahnical motion, is the reason that EV development largely stopped until quite recently. Efficient EVs are the pinnacle of materials and electronics engineering.

Paxos-based replication for Postgres
What the article doesn’t address is the potential for earthquakes. I thought that was the limiting factor in a lot of deep geothermal drilling? Didn’t Iceland run into this?
I think that rationale would apply to some other countries, but not all. For example, Japan should want to maintain a viable semiconductor manufacturing capacity (and might be at risk, currently). Now obviously Luxembourg cannot. Where exactly in between the size of Japan and Luxembourg one draws the line is a tough question, but probably western Europe has at least a couple countries (Germany, France, UK) who are big enough.

Lower-income countries like Brazil, South Africa, Argentina, India probably want to, but may have to work their way up to that; it's an expensive business to be in.

I notice that China has absolutely made it a top priority to try to get into this, despite having some difficulty doing so.

Start-up 1 (2000): Too early and inadequate access to technically sophisticated investors (located in the Midwest rather than Silicon Valley). Proof of concept in semantic knowledge graph but would have required computational resources to do it at scale that very few were building at the time. And, cloud wasn't a reality at that point. VCs started funding "semantic" about 7 or 8 years later.

Start-up 2 (2010) I was employee 7, not founder. It got through series A funding. We built it. We won award for innovation from Sloan School of Business and although CIOs of big companies professed to love the platform when they passed it off to their procurement and vendor management people adoption faltered. And, without a significant flow of RFPs being posted there was no revenue as we were going to get paid with commissions from the vendor side of the 2 sided market.

Start-up 3 (2012) - Solo founder builder. Lack of market fit. No funding, needed to earn a living so it went on the back shelf. Some technology still used for consulting clients but not as a product.
People have problems, go and meet people. Pick an industry you think you might be interested in exploring and then start attending their meetups and events. Speak to people, ask them what their problems are.

A great place to start is finding industries where most people you meet describe themselves as "not technical" or "bad with technology", they're often massively underserved. You'll know you've hit gold when you speak to multiple people across several businesses who all use some behemouth spreadsheet to run one of their core business processes.

Can you elaborate on this?

My understanding has always been that MOSFET is more ideal for higher-speed, lower-voltage operation, while IGBT is better for low-speed, high-voltage operation.

Re-using coal plant grid infrastructure is a good idea. So good that it's regularly done today, with big energy consumers like data centres setting up in those areas to save money.

Battery systems and solar are other initiatives that are currently re-using the existing lines.

However, while it makes a nice hook for a story, I'm dubious of any energy system that relies on that minor cost saving in established grids to be viable.

That is true for certain types of work but to the contrary for others. Projects where the risk of doing a poor job is within an acceptable range are those that one ought to give DIY a try. For instance, I've replaced bathroom sink plumbing at least 5 times on my own. The worst that has happened was that the connections weren't sufficiently tightened and water leaked until I addressed the issue. Cutting pipes too short would be an inconvenience but still not a big deal.

Usually the ones in the States are quite more expensive than ordering from the restaurant as well. GrubHub adds markup to individual food items, DoorDash does it via hidden fees.

The important discussion of sex and gender I think is done a disservice by every anomaly being presented as overwhelming evidence of a need for "redefinition." Nearly everything in biology that has a definition is defined along a median. If you take a single hair from a non-bald man, is he bald? One more? How about one more? It's an interesting question whose pondering may one day lead to a definitive answer, or it may not. Yet in the meantime we still generally know what baldness is (and sometimes we may disagree, and that's fine).

Anomalies exist, but each one is not a call to a radical change in thinking. It's a call to be examined, soberly and honestly, and to have the result of careful consideration submitted to further discussion and possibly inclusion in our knowledge of the natural world. Starting with a conclusion in science is destructive to both science and society.
I like the idea but the price seems very high and it’s not even for continued access but a subscription for a limited time.

The kind of experienced engineers you are targeting are also the people capable of doing this kind of learning on their own. But if someone’s employer is paying for it then it helps expedite the learning because of the guided process you guys provide.
I think this depends. Universities seem to have the power to generate "tuition waivers" that accompany TA positions and a few external fellowships such as NSF GRFP, but if you're funded solely from one or more of your advisor's grants, I believe that, at most places, the grants are actually used to fund the full cost of tuition. And as we all know, tuition is kind of insane at most places due to bloated admin.
