I think this is more of a focus problem than not having an interest in anything.

I heard 10 years ago, or whatever, that the ipad 2 had the most power efficient CPU available, period. This was told at a keynote by an HPC scientist who cannot be said to be a «apple journalist».

Over the summer I suddenly found time to work on some exterior projects around the house. It ended up standing in place of the evening commute as providing a physical and psychological barrier between close of business and my personal evening time. Lock my work computer, go outside for a while, come back in.

One of the things that has happened is I've hardly played a computer game in months, because I'd do that at the same desk I work at, and it's easier to lock the computer than to unplug it to plug my personal equipment back in.

As fall progressed I started filling in some gaps in my outerwear and kept going. Now that the sun is down before I finish working, I'm anticipating some trouble.

The new neutrality boogeyman folks had created during Ajit's appointment has turned out be false. Not only internet has grown stronger, but average speeds in USA are up by 91%. All the horror stories that people created have not come to pass. Deregulation has been better for internet in general.

This is not to say Ajit has been doing a stellar job. I am pretty pissed at him for banning phone calls on airplanes.

The reason automakers include cellular radios already is to do app-to-vehicle and vehicle-to-internet communications. Things like Internet radio or unlocking your car from your phone need the Internet, and cellular providers offer that. Presumably at a cut-rate deal compared to general-purpose cell plans.

The spectrum in question was being held for short-range vehicle-to-vehicle communications (Wi-Fi range stuff, hence why this spectrum will be... used for Wi-Fi).

So they're probably going to have the cellular connection anyways. And technically, it's not impossible for them to still use Wi-Fi bands... they're just likely going to have to contend with some more interference. I think more than likely, vehicle-to-vehicle communication should only be an additional indicator, not something to be fully relied upon, since other cars can "lie" to yours.
Very interesting, however now the problem becomes to characterize such machine learning approaches. With traditional simulation methods the authors can usually explain easily in which situation a specific approach is good or bad, with neural networks we don't really have a good approach how to analyze the quality of the prediction.
That is cool. I have so many projects with sqlite but all on my local machine. Is it possible to import an sqlite ?

You can use an uninterpretable model in conjunction with a post-hoc explainer—and in fact, this is most often how explainers are used. This gives you the best of both worlds: powerful models and auditability for their decisions.
I think I have to clarify that my response was to a large part to the "this will change all our lives" part, and might look too negative on its own. I'm very, very impressed by these results, but that still doesn't mean that we just solved biology. If this works that well on folding, this could mean that a lot of other stuff that simply didn't work well in silico might come into reach.

I'm maybe overcompensating for the tech-centric population here, with some comments speculating for very near and drastic impacts from discoveries like this. Biology and life sciences are much slower, and there's always more complexity below every breakthrough. That does tend to push me towards commenting with the more skeptical and sober view here.

Willingly declassify information? Ok this is hard troll teritory, I refuse to dig deeper.
Basically it boils down to responsibility. You can’t see the effects of your code if you jump around every year. Everyone thinks that they are good at writing code, until they have to maintain their own mess after a couple of years (not a month in production). Cowboy slinging is something we do for fun but as an adult we need to eat our veggies (writing documentation, choosing the language with a stable tooling, proper time estimation and everything else that seem unglamorous and easily dismissed).

but experimental methods have not solved protein folding either. AlphaFold has'nt solved protein folding but I can't wait to see their progress for ALphaFold 3.

What would be informatively useful would be to know how much accuracy is needed on average for drug engineers, I'd say that 99% is more likely to be the minimum to make solid inferences
To your main points, they have yet to fully utilize advanced packaging (TSMC 3D for example) to get much more RAM in the SOC. They could also go off package at the expense of power, a good tradeoff for a desktop system. The die size is also small compared to competitive processors (120 mm^2) so they can certainly add more cores. I think with a larger cost budget they'll make the high end sing.

I don't mean to pick on you as you're not alone in what is a very natural skepticism. However, it is somewhat amusing to watch the comments about the M1 over time. When Apple announced the M1 based products many critics were crying impossible, faked, rigged benchmarks, etc... Now that the products have proven to have performance at least as good as claimed, lots of people are suggesting this is some kind of low end fluke result and the higher end systems won't be so great. Just wait. I think we are seeing a tipping point event where RISC (fueled by great engineering) is finally fulfilling its promise from many years ago.
I don't think it would be possible to destroy a 10,000 sq km salt flat if that was even the intention.

>The approaches are that different.

I'm not sure if that analogy applies here. DeepMind wasn't the first group tackling structure prediction with machine learning. Their success lies in the innovations that they implemented (predicting interresidue distances as opposed to contacts, for example).
Out of curiosity, why not?

This sort of non-evidence based gaslighting it becoming depressingly common on HN these days. Ajit Pai has been a very competent individuals for the objectives he has been working for. One of the few in Trump admin who has skirted all controversies, done a good job quietly and delivered a good result despite so many people who earn their bread and butter from internet abusing him. ( I have even seen memes making fun of his skin color and face shape).

You disagree with his policies does not mean he is incompetent.
> "This uses 4266 MT/s LPDDR4X SDRAM (synchronous DRAM) and is mounted with the SoC using a system-in-package (SiP) design."

> Which implies to me that some kinds of LPDDR is indeed HBM and that what's on the M1 isn't something which can be replaced by drop in RAM.

Sibling comment already outlined that HBM is unique & different from LPDDR. Using LPDDR means it's definitely not HBM.

But you can definitely hit LPDDR4 at 4266 MT/s speeds with drop-in RAM. That's DDR5, which in the "initial" spec goes all the way to 6400 MT/s. More relevantly, DDR5-4800 (so 4800 MT/s) modules are among the first to actually be manufactured: https://www.anandtech.com/show/16142/ddr5-is-coming-first-64...
'Alien' TV Miniseries Is More Than a Rumor
We don't know too much about the exact model they made but it looks sufficiently generalizable to be able to give a candidate protein structure for any given sequence. It doesn't automatically cure cancer and inject the drug but that by itself is an amazing tool that if available to everyone will revolutionize biology experimentation.

I will definitely blame the protein structure field in multiple levels though. It was always frustrating to me to open up Nature or Science and see it filled with papers about structure - like they are innovating so much that half of the top science magazines every week have papers in that field, yet it's not going anywhere? Or is it simply just a bunch of professors tooting their own horns about ostensible progress in a field that's archaic by decades if not years? The overall protein structure field internalised some dogmas in self defeating ways to everyone's detriment and finally events like this (and Cryo em, maybe) will jolt them out or make them fully irrelevant so we can move on. it's only doubly ironic that this came from a team in a company with minimal academic ties showing how toxic that entire system is. I only feel pity for the graduate students still trying to crystallize proteins in this day and age.

Yes, and in addition to the requirements file, pip supports a constraints file, which is the lockfile you describe. It's separate from the requirements file. It solves exactly this problem.

Latencies like this are doable with a lot of tuning on Intel CPUs; out of the box you'll get to the 40s with fast memory. And those CPUs have three cache levels instead of two...

A good old-fashioned 2010-era gaming PC would already get down to around 50 ns levels.

It's definitely really good, but considering it's rather fast RAM (DDR4 4266 CL16) and doesn't have L3 it's not that surprising.
> In today’s COVID-19 wars, the global scientific divide leans heavily in favor of active, and sometimes even draconian, public health interventions, including widespread locking down of nonessential business, mandating masks, restricting travel and imposing quarantines. On the other side, some doctors, scientists and public health officials are questioning the wisdom of this approach in the face of massive unknowns about their efficacy and in light of the clear and growing evidence that such measures may not be working in some cases, and may also be causing net harm.

It's very hard to dissent against the current narrative because any dissent can easily be framed as "killing people". I blame technology for our current predicament. If we didn't have computers and a global internet, there's no way we would be shutting down everything. We might be wearing masks and washing hands, but I would bet life would be largely the same.

But because technology dangled the carrot of "we can save lives by doing everything virtually with computers" we are charging down that path optimizing for lives saved without giving fair consideration to other side effects of that (loneliness, depression, suicide, homelessness, civil unrest, economy). In some ways, taking a one time "excess deaths" hit as we have done with past pandemics does have measurable benefits in other ways, but you'll get shouted out of the room if you bring up that position even as a hypothetical.
Power 10 does have some nice features so it would be pretty nice to see IBM seize the opportunity, not that they will.

Considering how few people know what HBM2 is, the idea that Apple is trying to make any claims that their solution uses HBM2 seems weird.

How would you know? Absolute blocks are one thing, artificial performance differences another. If your ISP was slightly reducing the performance of one streaming service to advantage another, how many people would actually test for this? If a phone maker (apple/google/whatever) was feeding an ISP money to ensure their phones would be that little bit better on the network, wouldn't most people chalk that up to differences in hardware? True evil survives by being difficult to detect with certainty.

I can bring up unreported crimes in India which are a whole another animal. At least the rule of law is followed to a much higher degree in Indonesia (except for Aceh).

And is the Dutch-Roman system a perfect legal system to be followed by their former subjects? Sometimes the folks on this site are laughable. Those provisions exist because the rules of that period, and of the former colonial power are barely applicable in any part. In fact, India and Singapore are some countries that still suffer from the imposition of outdated British laws under an "Anglo-Roman" legal system (eg: the sedition laws which can be used to silence any opposition). Colonial laws were very different from the laws imposed in the home countries. And very discriminatory too. Of course, if they're going to directly port the legal system (to maintain a semblance of order during transition), they might also incorporate caveats so that BS laws can be revised.

I think there's some merit to the idea that huge corporate monopolies have the resources to accomplish undertakings that smaller companies cannot. But it's often a what-if, because we don't know what the alternative might have been.

Big companies can suck up all the air in the room by monopolizing talent and making it harder for startups to pay the kinds of salaries needed for top tier AI research. Xerox PARC came up with all kinds of groundbreaking inventions that were never commercialized (by them). For every invention that comes out of a big company, it's worth thinking about whether it might have actually come out faster if it was borne of competition instead of a side project. Or in the grand scheme of things, if corporate taxes were higher and the money was given to a university research lab.

I think the best results may come from the middle ground. Smaller/medium companies are so worried about staying afloat or hitting their quarterly earnings that they have trouble making long term investments. Large companies are diverse and profitable enough that they can afford to blow money on things that might not pan out, but they don't have the same drive -- and in fact have some pressure to avoid being "too" innovative because it could cannibalize their existing products.

AI solve the process but doesn't give a whole lot of insight into the formulas and the description what's going on. Where we as humans have reasonably found that e = mc^2. However AI would gives us e or m but backboxes us away from seeing that c aka the speed of light was involved(unless we implied that before). There might be interesting relationships that are useful that AI unintentionally masks that could be ground breaking if we could only understand process more holistically. I think a different commenter eluded in this case we think we understand protein folding well we just struggle to synthesis it in a compact mathematical way even though with AI we can simulate the process well for known examples.

The issue with AI is we don't know if our current example set includes every case what if there is a strange sequence of amino acid that causes something "weird" to happen that we have haven't seen. AI cannot predict something novel it or us haven't seen which is the issue. The process(if it exists) of how one could solve this problem might also be exportable to other fields if it was formulized with math rather than estimated with AI.
This just reminded me of my own experience with the app stores. If Google or Apple put you on one of their "top whatever" lists, it's an incredible difference in number of downloads. It's not even comparable to word of mouth or third party advertising for your app. That "front page" real estate is gold.
Dunno, increasingly with machine learning, more cores, GPUs, etc the bottleneck is the memory system. How much are you willing to pay for a dimm slot?

Personally I'd rather have half the latency, more bandwidth, and 4x the memory channels instead of being able to expand ram mid life.

However I would want the option to buy 16, 32, and 64GB up front, unlike the current M1 systems that are 8 or 16GB.

In short, a core problem of biochem (the wagon) was just hitched to Moore's law (the horse). Our understanding of proteins will now grow exponentially not linearly, helping us to move up a level of abstraction to higher level biochemistry and biology problems.
> I wonder if we can determine if this extends to proteins that aren't as keen to determining their 3D structure?

This is already happened.

"An AlphaFold prediction helped to determine the structure of a bacterial protein that Lupas’s lab has been trying to crack for years. Lupas’s team had previously collected raw X-ray diffraction data, but transforming these Rorschach-like patterns into a structure requires some information about the shape of the protein. Tricks for getting this information, as well as other prediction tools, had failed. “The model from group 427 gave us our structure in half an hour, after we had spent a decade trying everything,” Lupas says."
