I don’t think this author understands Dijkstra’s essay the way I understand it. Dijkstra was very specific about advising people to not assign agency to computer programs, nor to rely on operational reasoning. However, the cited examples involve either the explanation of the concepts of programming (rather than reasoning about a program itself), or the very same thing that Dijkstra exhorted us to do... read what the program “says”, i.e. its denotation. Reason about it mathematically and logically, deducing its nature, instead of watching it like a mechanism and abducting various properties.
It's not so obvious to me. Take for example Switzerland. Second wave hit it very hard. Since a couple of weeks it was however able to bring R0 down below 1 while keeping schools, stores and restaurants open. This is far from a controlled study, but the conclusion has to be that a combination of distancing, contact reduction and mask wearing is working. Note that Switzerland is densely populated and currently has relatively cold and dark weather.
Well, you'd be surprised how much great research doesn't make it into Nature, et al. I wouldn't discount the paper purely because of that.

Yes, consider vector floating point fused multiply-add (FMA). On a typical AVX implementation like Skylake, this instruction has a latency of 4 cycles and a throughput of 2 instructions per cycle. To avoid stalls, you'd need 4 * 2 = 8 instructions to run independently, and 8 architectural registers to simply store the results. You could store the results onto the stack and reuse the same architectural registers, but usually you want to use the values immediately in the next loop iteration (eg. matrix multiply) so this would be expensive. You probably want a few more architectural registers (at the very least 2, up to 16) to hold the inputs as well.

“Original assignments” as in everybody has a different assignment? If so, dang that sounds like a huge time investment to create and grade for the prof and TAs.

WRT legal consequences for cheating: I mean, you can get kicked out of university. That’s a loss of thousands of dollars invested. And as a TA, if I knew I could be called in to testify in court every time I caught a student cheating... I’d never call it out. I don’t have time for that! And that still wouldn’t change that we’d have to be on the lookout for cheating.

> That still doesn’t explain how Apple built an 8-wide CPU with such deep OOO that operates on 10-15 watts.

Well, because it doesn't, it's ~25 watts. And also because it runs at just 3ghz. You'll see similar power numbers from x86 CPUs at 3ghz, too. The M1's multicore performance vs. the 4800U and 4900HS demonstrate this nicely.
I completely forgot that 11th gen Intels actually supported LPDDR4 / LPDDR4x.

Its kind of ridiculous: LPDDR4 has been used in phones for years, but it took until this year before Intel / AMD added support for it. Ah well. This one is definitely on Intel / AMD's fault for being slow on the uptake.

DDR4 had largely the same power-draw of LPDDR3 (but was missing sleep-mode). So I think CPU makers got a bit lazy and felt like DDR4 was sufficient for the job. But LPDDR4x is leapfrogging ahead... the phone market is really seeing more innovation than the laptop / desktop market in some respects.

24-cells in a 600-cell
The 24-cell is a four-dimensional regular polytope with 24 vertices and 24 octahedral faces. The 600-cell is a four-dimensional regular polytope with 120 vertices and 600 tetrahedral faces. Since 120/24 = 5, you might hope that there’s a way to partition the 600-cell’s vertices into the vertices of five 24-cells.

And there is! A new paper by some high school students shows what we've long believed: there are exactly 10 ways.

In fact, they show there are 25 ways to choose some of the vertices of the 600-cell to be the vertices of a 24-cell.
These 25 ways can listed in a 5×5 array, so that each row and each column gives one way to partition the 600-cell’s vertices into the vertices of five 24-cells.

For details and pictures go here:

On top of the great points made by sibling comments the Apollo Lunar Modules landed propulsively from orbit with an additional party trick of having humans on board.

Also Blue Origin actually did propulsive sub-orbital landing from space to Earth before SpaceX, although admittedly from a lower altitude and velocity. Both came after the 1990s era Delta Clipper. Before that there were probably a lot of Apollo era test vehicles.

Each one got a bit higher and faster. This is the value SpaceX offers. They're doing the hard work of making things we know are possible also commercially viable.

In reverse order:

Offline+subkey PGP is about enabling a root of trust that isn't exposed by exploits. Forward secrecy is about deliberately and frequently changing keys so that a point-in-time compromise can't be used to rewind all your previous communications. They are not the same thing. In particular: offline keys make it much harder to switch keys, which is exactly what you don't want. I don't think it's reasonable to suggest that the OpenPGP protocol contains the bones of a forward secrecy system --- it does not, it's just something people talk about grafting onto it.

Regarding deniable messages: the ability for an unrelated Mallory to confirm a message Alice sent to Bob is a vulnerability. It leaks a piece of information to the world that only Alice and Bob needed, and that both needed only for a brief moment in time. In the real world, nobody pays any attention to any of this stuff, which makes the vulnerability worse: non-repudiability is virtually always moot except in the circumstances where you need it not to exist.

If you're using ZFS, you're already okay with some level of ignoring that; ZFS is a inherently huge layering violation. It's a filesystem and a volume manager with encryption and compression, its own user access system (zfs allow), and its own NFS implementation.
It’s funny you mention SPARC because MIT is treating it as a business opportunity. Their REBCO coil winding work is both private and proprietary. This is very much not how the fusion community (and physics at large) do things. The openness of fusion research was a component in ending the Cold War. Researchers building machines right now want HTS coils. MIT is making sure they’re the ones to supply them. Who makes money in a gold rush? The pickaxe company.
Then you’re mainly testing oral English skills.

Also, in most subjects I could mark an exam in a fifth of the time it took a student to write - whereas with oral exams it takes at least as long as the exam took. Quintupling the load on TAs and profs sounds like a raw deal.

Not really. Using a statistical approach to text modelling, specifically using Markov Chains, was proposed by Shannon in 1948. But yeah, there's a point in the 2000s where generative grammar/ symbolic approaches were pretty much left behind by NN methods.

That already happened in the ITER development process with early version safety sitting on people’s desks. Sometimes you get an awesome breakthrough that makes everything work, other times no so much.

ITER is designed to be a test bed not the final design. Plenty of advancements have taken place after the design was essentially finalized, but none of them actually help test things like heavy neutron bombardment of a lithium blanket.
Took a closer look at the study and the patient population was from a small town in Germany, Heidelberg. It'd probably be a fair guess that there's not a lot of variation in the patients' ethnicity so in this particular case controlling by race probably wasn't necessary.

This observation makes me more confident Vitamin D plays a role.

In any event, good to review studies for potential issues like this.

Dev dependencies: a library you need during development, but that isn’t needed in production. I think your -test and -dev are this, but it’s not clear how you are maintaining all of these, and building for prod.

This is the main complaint, most modern languages have a standard set of tools and flows for achieving this. Python doesn’t, and everyone does it a bit differently, and when starting a new project, you have to hand roll your own flow.

Or, use something like poetry but the python community as a whole doesn’t have a commonly used solution.
One option, if you have a reasonably low student-to-instructor ratio: make it an oral 1-1 exam for each student. A video call with the instructor and the student; you ask questions, they answer. If you have 20-ish students, it will eat up half a work-week or so, which is more work than grading 20 exam papers, but not _that_ much more.

Of course if you have 50 students per instructor this is not going to work...

Oh, I think I see. I don't think there's such thing as a problematic mail for BEAM really, mails are just terms, and BEAM handles terms, no problem. A mail that contained a small slice of a very large binary, would of course keep the whole referenced binary hanging around, which could be bad, or a large tuple could be bad because if you tried to inspect the message queue through process_info in another process, that would be a big copy.

But I think maybe the original poster just meant lots of bad mail in the mailbox to mean mail that would take a long time to process, because of how the receiving process will handle it.

Or, possibly bad mail meaning (as you suggest, perhaps), mail that won't be matched by any receive, resulting in longer and longer receives when they need to start from the top.

I don't consider it being ahead to be disinclined to propagate the human race. I mean, if you're just advocating that for yourself that is one thing. But advocating that as a position in general is misanthropic and in my view not a tenable or healthy position.

In any case, if you don't care about the risks and are just concerned with the meaning about why we propagate and what the point of anything is, then I must point out that I'm not super interested in discussing this. I was more getting at why someone would oppose transhumanism, but this doesn't seem tone a meaningful critique of transhumanism as much as it is a sort of pessimism about why we do anything or we should propagate at all.

I upvoted you because I want to discuss your point.

I have a theory that homelessness is an industry that employs tons of people who are unable to find work elsewhere. The homeless are the product.

Non profit org, public sector employees, donations, city employees, univ PhD researchers, grants etc...for every dollar, more than 60%(I will have to look up the exact number)..will go towards managing the homeless rather than aiding the homeless find a roof over their heads.

This might seem like a cynical way to view this but there is no reason why SF is spending in excess of 500 million dollars in ONE YEAR and still have homeless on the street.

There is literally zero incentive to solve homelessness. Now imagine the problem is resolved..how many people will be out of work? These are not drug addicts or mentally ill..they are educated and normal functioning people who need jobs..they need to be employed. Without a job, they will be unemployed and likely unhoused due to economic necessity.

Of course, people can migrate out of bay area. That would be the rational thing to do. Millions of immigrants do this every single day. But Americans won’t travel coast to coast in the worlds most boring homogeneous country where any freeway or Walmart or mcD in CA is no diff than in NH if economic survival and upward mobility is the imperative.

That’s my 2c anyways.

Ask HN: Why are drawing tablets so expensive?
I had a Christmas present request for one and was shocked to see how expensive they are.

Is it just because it is a niche product? Or is there some sort of special hardware that makes them different from regular tablets? Do these tablets somehow make people draw better?
I don’t agree with this approach, the biggest value of a university degree is teaching someone how to think and learn in combination with some domain knowledge. Unless you are going for higher degrees, the specialization isn’t of prime importance. i.e. what one engineer/scientist/scholar learns within their field in undergrad compared to another is really not so important for their ability to do things related to that degree. You don’t need to be exclusively prepared for your exact job.

We have accreditation boards to determine what is required for a common base.
What evidence is there the open web is dying? At least here on HN I'd categorize 25 of the top 30 links as open web links.

Replacing a core system component with an out-of-repo version is always going to hurt, yes.

I'm not sure I'd call "catastrophic failure and data loss" a "wart". In all my years of distro hopping, I've had 3 root filesystems become unbootable: 1 F2FS system early on, which I actually did manage to fsck out of, and 2 on an openSUSE tubleweed system using BTRFS as root.

The paper's title is Purpose-First Programming: A Programming Learning Approach for Learners Who Care Most About What Code Achieves

This URL's author says the paper's author "invented purpose-first programming," but I think it's proper to clarify that the paper's author has demonstrated positive results from a different ("new"?) learning approach, and then named it "purpose-first programming."

I would argue that "we" already value purpose-first programming - we're concerned with what the software does moreso than the syntax required to make it happen. But academia, anecdotally, doesn't usually value purpose-first programming.
Isn't 401k tax-free in the US? At least where I'm from, people put money into these kinds of pension funds since they don't have to pay any tax on the profits, which is usually enough to beat any other low-risk investments.
I sent the message with the same sentiment during the spring to our country's head of covid-19 coordination after he claimed in a news paper article that the hospitals are ready for the battle.

I told to him that if covid hits hospitals then the war is lost because hospitals are the rear where the fallen are treated. The fight must happen before by using prevention tactics.

I am not sure if he ever read it or made any conclusions from it but I felt necessary to send it after the article.

I often arrive at our offices in the dark, and then leave after dark. In the meantime I'm in a windowed corner office but like others have said - filtered light. I take 10k IU's of vitamin D per day. Absent that, my natural (un-supplemented) vitamin D tests come back with a level about 20+ (30-100 being the desired range).
Also, an actual peer reviewed paper came out recently that showed giving vitamin d to covid patients upon admitting them did not decrease death rates. I'll look for the link but it was front page here like two weeks ago.
Any fusion reactor in this century will likely be putting out a Lot of fast neutrons. These fast neutrons can turn otherwise benign heavy elements into weapons-grade fissile material. There are detection techniques for this kind of breeding and I’d imagine any country capable of building a fusion reactor would also be okay with audits. If you just want weapons-grade fissile material, there are far more economical avenues than a fusion reactor.

Also, if fusion reactors become more viable than fission reactors, then we could put a global ban on all fissile materials. They would serve no purpose except for weapons.

In this scenario, it took the focus off memorizing things and instead focused on understanding the content and being able to communicate something worth reading.

Intel’s 10nm is equivalent to TSMC’s 7nm, so we’re just talking one generation on the process side. I don’t think you can chalk a 75% IPC gain to a die shrink. That’s a much bigger IPC uplift than Intel has achieved from Sandy Bridge to Sunny Cove, which happened over 4-5 die shrinks.

The total performance gain, comparing a 4.7 GHz core to a 3.2 GHz core, is 20%. But there is more to it than bottom line. The conventional wisdom would tell you that increasing clock speed is better than making the core wider because of diminishing returns to chasing IPC. Intel has followed the CW for generations: it has made cores modestly wider and deeper, but has significantly increased clock speed. Intel doubled the size of the reorder buffer from Sandy Bridge to Sunny Cove. Intel increased issue width from 5 to 6 over 10 years.

If your goal was to achieve a 20% speed-up compared to Sunny Cove, in one die shrink, the CW would be to make it a little wider and a little deeper but try to hit a boost clock well north of 5 GHz. It wouldn’t tell you to make it a third wider and twice as deep at the cost of dropping the boost clock by a third. Apple isn’t just enjoying a one-generation process advantage, but is hitting a significantly different point in the design space.
