> but the WD sn850 blows away the 980 pro in nearly every benchmark.

I think they have some cache tuning differences, because while WD wins in many benchmarks by 30-40%, it losses the same 30-40% on long sequential writes.

I have no ssd expertise, so, can't comment why this could happen.
If the price point of the Optane is keeping consumers from embracing them, then why not look for another way to make something the consumers are willing to buy? That's kind of what WD does. They have a huge chunk of the consumer market.
Not by 2045, at least not likely. The theory that for every thing you might want to manufacture, an infinite universe must contain a planet where it grows naturally is older than most people on hn, but I doubt that we'll find planet Raviolon that soon. How would you even start a serious SETP Project without a smelloscope? (scheduled for y3k)
To clarify, "racial differences" generally meant "genetic differences". So a better way to put it is not race vs. culture, but genetics vs. culture, as ethnic groups (or more broadly speaking, races) can have both different genetics and different cultures. In other words, nature vs. nurture. You take people of different races, look at the differences between them and then study how much of the variations are due to genetic or environmental causes. "Racial differences" I guess could mean both genetics+culture.
I believe the answer is yes, but this receives fairly little attention because people are more concerned about Bitfinex treasury and the USD backing than they are about the ethereum dependency

You are right that METAFONT allows a font designer to vary the font in a continuous way using parameters while retaining its essence. But this is addressing a different problem. It allows a document designer to adapt the font to the page.

I suppose this approach could be used together with the METAFONT approach so that the font itself varies as needed, too.... but my head hurts thinking about it.

> The OP wants to study EE because he has a specific goal. My suggestion was that instead of trying to study everything EE focus only on those subjects that are relevant.

This is something that I've seen often in self study plans for software development - the "learn everything and then try to use it" rather than "learn what you need to start solving the problem... and start solving it."

In software development this often takes the form of a self-learner learnings Java, JavaScript, Python, C, and C++. Once in an interview it becomes apparent that they don't know enough about any one language to solve a problem in that language.

This is where a university class (and degree) have an advantage - they've got a set of problems for the student to solve (homework and labs) and then take the student through learning specific knowledge to solve those problems.

This also shows what self teaching often lacks - those small problems that can be accomplished as part of learning how to solve the big problems.
Great questions! I've actually never considered putting the comment first! I'll have to think about that one.

You're right to point out that there are two components to "C compilers written in C make compilers seem complex": the metacircularity, and C-specific difficulties. I think I was focusing on the first when I wrote that, but I can't exclude the possibility you raise. A better language might reduce the need to understand it operationally, by looking under the hood to understand what a line of code is translated to. The Mu way may well be a dead end, since the requirement of understanding translated code restricts how complex compiler optimizations can get. You probably don't want to understand Haskell's loop fusion by comparing source and generated code.

In my mind there's an idea maze where there are 3 major possibilities for improving the future of software:

a) Simple languages and translators that are easy to understand by running them. This is the Mu way.

b) Type-driven languages that are easy to understand by reading them. Haskell and OCaml seem to fit here, and they may well be the right answers.

c) Complex languages that discourage abstractions atop them. This is the APL way, and it too might end up being the right way.

I'm doing a) mostly because it seems to fit my brain better. I just can't seem to get into Haskell or OCaml or APL.

> postmodern thinkers can get very meta in their arguments

In my experience 10 years of arguing intellectual subjects on the Internet I noticed that those who focus almost exclusively on the intellectual impact of an idea tend to neglect to even consider the merits of the idea itself. Not dissimilar to what is happening with String Theory in physics.
> I was referring to your argument that "popularity contests don't think much of unpopular (i.e. minority) forks".

So am I, but you're interpreting my words wrong.

I wasn't saying that "in the realm of blockchain forking, the less popular one will be less popular", which would be a tautology. I was saying that "in the realm of blockchain forking, the less popular one will get demolished".

> The thing called 'Ethereum' at the time is now called ETC, and it lost.

Right before the fork, they were both called Ethereum.

Right after the fork, ETH was called Ethereum. And it won.

"at the time" and "the day after" are supposed to be roughly synonyms in my comment there.

And you didn't address the issue of how validation logic has changed many other times on coins, with the original continuing to mine for a while before sputtering out and dying. Is "Bitcoin" dead? Nobody is running the original logic anymore.
Check out the sequential 128k read at queue depth 16: https://images.anandtech.com/doci/16505/sr-s-sn850-1000.png

That's >2x higher throughput than an Optane at equivalent queue depth and (as far as I can see in the UK) at less than a tenth of the price: https://www.scan.co.uk/products/2tb-wd-black-sn850-m2-2280-p... vs https://www.scan.co.uk/products/15tb-intel-optane-dc-p4800x-...

And that's 7 GB/s from _one_ SSD. Aggregate memory bandwidth on something like the Zen3 is roughly 40 GB/s. These are also first generation PCIe 4, plenty more to come.

Doesn't require a huge improvement before you end up in a position where you simply don't have the memory bandwidth or cycles to deal with more than one drive.

I suspect the Optane wins most of the benchmarks because of it's outrageously good low queue depth random read performance - that's very effective for software that's not written for modern NVMe SSDs which benefit from very high queue depths. Check out the 4k random read performance from the SN850 at high queue depths:

https://images.anandtech.com/doci/16505/rr-s-sn850-1000.png

If you can keep the queues deep, it manages to beat the throughput of the Optane. You've got to design algorithms and data structures to exploit that kind of concurrency though.

I can go one step further, based on what I've seen - "Shadow IT" that has its own help-desk line and ticketing system... Running their own LAN with interconnects to "main IT".

The end result is that nobody ever lets "main IT" near anything. Most people who have important work on the go used shadow IT. People who know what they're doing then run their own personal Shadow IT (but would use the real shadow IT if they had any issues like needing to reinstall a system, as that way it won't get connected to the main IT domain...)

You are absolutely correct - it's an absolute nightmare. Many university networks originate from the era of the flat LAN, where every system got a routable public IP, reachable via the internet. There are people running all kinds of servers and services and jobs across the network. None of them are documented, some might be relied upon by important internal or external things...

There's no standardisation of hardware generally. If you're lucky there's some managed desktops using standard configurations for computer labs used by students, and office administrative staff. Don't expect to be able to tell professors what they'll use - they're buying computers on their research grants for themselves and their teams. And their own NAS servers and everything. Heck the "shadow IT with a help-desk" was even offering storage and VMs on their shadow infrastructure.

I've seen people trying to use Windows XP on the network because some incredibly expensive piece of equipment needs it, and they would like to be able to browse the internet while they wait on it to do its work (!) Fortunately, shadow IT were on the lookout for that, and helped them set up a second computer on a supported OS, and get the XP box offline.
>Who says 90s American cars are bad?

The well 20-something yuppies who got dragged around in their parent's well cared for 90s Japanese cars and look back fondly on those days.

The edge between manufacturers is very, very, small. 20+yr and 3+ owners later how a vehicle is treated will completely dominate who made it when it comes to how reliable it is going forward. 90s domestics definitely ignored the sedan and compact market a little, after all, minivans then SUVs were where they money was. They didn't innovate. But they gave their car platforms the same sets of tech and systems that the flagship SUVs got so they're no less reliable. The "hurr durr domestics are unreliable" tropes that HN loves comes from the fact that they're cheap (compare MSRPs of the day if you don't believe me). So people bought them with the intention of treating them as disposable. So then they don't hold their value, so then they get sold to people who can't afford to do maintenance. And the cycle continues.
This is ABC of SQL: every SQL developer has to learn this lesson soon or later: Every additional JOIN you make creates a cartesian product of all previously joined records and the number of rows grows exponentially => you join tables A to B to C to D -> SQL engine has to create AxBxCxD number rows, each letter representing number of rows in that table)

Of course specifying useful predicates that filter down dataset and having indexes on these columns helps avoid row explosion, but you can't have an index on each and every column, especially on OLTP database.

in example #2 the author joined 7 tables (multiply row count of 7 tables and this gives you an indea of how many rows SQL engine has to churn through) - big O complexity of query is (AxBxCxDxExFxG) of course it will be SLOW.

in example #4 he joins 4 tables and unions with 5 table join, so the big O complexity of query is AxBxCxD(1+E).

same as in programming, there is Big O complexity in your SQL queries, so it helps to know O() compelxity of queries that you write

TLDR: learn the SQL Big-O and stop compaining about the query planner, pls

Can you respond to the point made by Sneak downthread that there is silent data transfer to your company in the background?
Probably not. I'm thinking of things like Laplace transforms and their relationship to differential equations, and stability analysis for things like amp feedback. Most of that you should have gotten academically in physics, just with a more specialized application when applying it to how you model an inductor or capacitor for instance.

But if you can design an amplifier or power supply, you probably already understand how to think of all the basic circuit elements and write down a differential equation modeling the circuit behavior.

With respect to RF, it's also a large field. In lower frequency regimes you can model everything as a lumped circuit element. As you get into higher microwave frequencies, you start needing to worry about modeling things as a distributed circuit. If you are focusing on things like antennas then you need to know more about electromagnetics. These days practicing engineers dealing with things like antennas and feedlines typically model them with computers. In some ways RF analog circuitry is disappearing as ADCs and associated digital circuitry are becoming advanced enough to swallow large bandwidth signals.

In many ways EE is pretty close to "applied physics", just focusing more on emag and less on mechanics.
Thank you for the clarification and citation. Your answer is the best of several.
I think that lot of math curriculum does not really make clear to students the rationale for why they cover the topics and proofs in the order they do. The students lose the big picture of the path they are on, why is it important for me to be working on this right now, so that I will be able to tackle the next subject when that comes along. The structure of theorems and proofs and how they all build upon one another is not presented clearly. The point of a proof is not to prove something, but what further proofs this proof makes possible. NO?

Nope, immunity to a given poison doesn't really work like that.

The biggest issue with poisoning operations is when the animals become bait shy, then it dramatically reduces kills, hence the popularity of warfarin for rodents - they don't associate the poisoning with ingesting the bait, so don't become bait shy.

I suspect in smarter social animals, bait shyness could be passed along as communal knowledge.
In NZ we also use "pre-feeding" where the baits, without poison, are dropped for some time to teach the target species that they're good eating.

Predator by-kill can be a real issue though, and I guess it depends on whether the predators are pests also - like foxes and cats in Australia, mustelids in NZ. There's a reason NZ is the biggest user of 1080, there's no carnivorous mammals in our forests that we want to stay there, so if they eat a poisoned possum or rodent, bonus.

That said, Australia has carnivorous marsupials that are highly endangered, so it'll be a different ballgame over there.

I understand the problem. I used to manage an English academic writing program at a university in Japan, and what guidance to give to students about pronoun usage was a frequent topic of discussion among the teachers.

One problem was that the students had learned a moderately informal version of English in which first-person pronouns are common. Also, they were young and used to writing and speaking about themselves. That led to what some teachers perceived as excessive use of “I” for the research papers the students were being taught to write.

Another issue was that the teachers themselves all had academic backgrounds, most with doctorates, and, we discovered through our discussions, pronoun usage varies a lot by field. Curious, I once looked through journals in a variety of fields—sociology, nursing, physics, gender studies, literature—and found that in some fields the authors never seemed to refer to themselves by “I” or “we” while in others it was common.

The use of “we” in mathematical writing, especially proofs, may be a special case. The “we” in a sentence like “If we assume that M is a compact metric space, then we can prove that ...” doesn’t really refer to the author or authors; it seems to have a more abstract referent.

Paul Halmos, by the way, was an excellent teacher as well as writer of mathematics. I was fortunate to take several classes from him when I was an undergraduate at the University of California, Santa Barbara, in the 1970s. Though I ended up not going into mathematics, I still have a very fond memories of learning with him.
