The limiting factor is the fact that positioning the head on platter one to access track N does not guarantee that the heads on the other 8 platters are positioned over track N on their respective platters.

Nor indeed does each platter even have the same number of tracks at the same spacing in modern drives. Ever since embedded servo became the norm for hard drives (late 80s), there hasn't been a need to align each platter with the others.
> As I explained, you are describing processes, in the Linux parlance, with a shared mapping.

I'm not describing processes because I'm not describing anything that currently exists, at least not in Linux or any other popular OS.

I may not be a maintainer for any current VM subsystem, but I've been around long enough to know it's ridiculous to get into semantic arguments about processes, threads, light weight processes, or other similar labels. The meanings behind such terms continually evolve and are dependent on context--particular operating system, hardware, etc.

If it's not possible to implement the OP's notion, please explain why it wouldn't be possible with current hardware; why one process'/thread's/LWP's/whatever's mapping table couldn't have a subtree shared (not copied) with another mapping table which could be manipulated with the appropriate semantics. I don't know if it's possible or not; that was the gist of my question. I don't need a lesson in how "process" and "thread" are currently defined and modeled in typical systems. Obviously they don't model what the OP was suggesting. You've hinted there might be hurdles with keeping the TLB coherent, but you haven't come straight out and said that yet. It would be genuinely interesting if you asserted the claim squarely, perhaps with some context about the relationship between TLB management, root page mapping address, and scheduling contexts.

EDIT: And just to be clear, I understand that in Linux processes can share memory, but the page table entries to the shared physical pages are copies, not references to shared entries, which is why both the protections and virtual addresses can be different. In the OP's proposed scheme having to maintain N copies of those mappings would obviously defeat the purpose; why even bother with threads if every time pages in the shared address space are mapped you've have to update every thread's page table--dozens if not hundreds or even thousands of separate tables. That's facially preposterous and it didn't even occur to me it needed to be stated explicitly, at least not in a forum like this. The whole idea clearly poses some difficult dilemmas. But because only allocations in the shared space need be globally atomic and simple--as they are now--it's not obvious that a scheme with private mappings on the side is impossible; at least, not obvious without recourse to specific knowledge of the details of how typical MMUs, TLBs, etc operate and are managed. And I wouldn't be surprised in the least if it's not possible to achieve what the OP suggested. In fact, I've been skeptical the entire time. I just don't have enough knowledge myself to explain clearly why it's not possible, and was hoping somebody would do that.
which company's press release is this from?
Most of those "billions of planets" cannot support life (the exact number of which can is currently unknown). And who says no life evolved "capable of spreading out of its gravity well"?

> As for Dyson spheres, don't take the remark so literally.

Of course it should be taken literally, because all of this is all about what the laws of nature do and don't allow and the practicalities surrounding that. This isn't an class or discussion about what does and doesn't make a good sci-fi story. And what is a "galaxy-spanning slime mould" even?

Yes, it would be. There is no intelligent life living near thermal vents. What an odd thing to say.
This is the best post I have read in awhile. Thank you.
Thanks, I wish that was stated a little more clearly is the source document.
I've been using it for all kinds of stuff. I was using a drying machine at a hotel a while ago and I was not sure about the icon that it was display on the visor regarding my clothes, so I asked gpt and it told me correctly. It read all the manuals and documentations from pretty much everything right? Better then Google it and you just ask for the exact thing you want.

That comparison is pretty harsh and really underemphasizes how awful sourceforge was. Myspace was mostly fine, death by feature creep. Sourceforge was a flaming pile of garbage that was poorly designed, ad laden, AND silently bundled in ad/spyware to normal downloads.

A more apt comparison would be comparing Facebook to a hypothetical social media site that when you click on a thumbnail of a user's image, you get a fullsize image of something like goatse...which thankfully doesn't exist(yet).
Its all in expectations I guess. We have been focusing on balancing yield with investment. If we can get half the production for a quarter of the work, we'll take that trade off.

We've actually been running a test this year that has been interesting to watch play out. Our garden isn't very dense comparatively, and its planted into what was pasture before. We did cut the grass when planting and have trimmed it a few times, but its far from a garden free of weeds.

We also planted a space along the lines of a milpa or a chaos garden. We planted corn in rows, untilled and effectively just a grass pasture that we clipped short to start. When the corn germinated we followed behind with a variety of beans, peas, squash, and greens. It isn't nearly as productive per foot as it could be, but we haven't put much time into it beyond planting and a few deep waterings during a drought.

I think an hour a day is a totally reasonable expectation. To me that's worth it, but that wouldn't work for everyone and finding an hour a day may not be an easy ask depending on your lifestyle. I would argue, though, that if it isn't worth an hour a day to you you probably aren't too concerned with growing a large portion of your own food.
Back when I lived in Portland 20+ years ago, just as it was starting to turn into the version of itself that would be sent up in Portlandia, I used to tell relatives back east that culturally Oregon is to California what California is to the rest of the country.

Nature isn't perfect and has disadvantages compared to us.

We don't have to invent ex post facto explanations for why something is the case in nature or why there is some un-intuitive reason as for why the natural way is better.
I had an absolute blast playing with p5.js in college - I made my own little cellular automata with it back in the day: https://ezhik.me/beyond184/

As a wonderful coincidence, the piece of digital art that got me interested in digital art in the first place - which is a delightful tribute to computing - also used p5.js: https://baku89.com/work/ffff?lang=en https://animethemes.moe/anime/subete_ga_f_ni_naru_the_perfec...

I think one of the hardest things for me as a programmer is getting through all the boilerplate to put the first pixel on the screen and p5.js solves that pretty well, letting me focus on more on the "creative" aspect of "creative coding".

I probably wouldn't use p5.js for Big Boy Software Development, but whenever I want to sketch, it's the first digital tool I reach for.

The two best classes for me are definitely:

- "things trivial to verify", so it doesn't matter if the answer is not correct - I can iterate/retry if needed and fallback to writing things myself, or

- "ideas generator", on the brainstorming level - maybe it's not correct, but I just want a kickstart with some directions for actual research/learning

Expecting perfect/correct results is going to lead to failure at this point, but it doesn't prevent usefulness.

Heritability is, literally by definition, the measured difference in some value (like IQ) between people that is attributable to genetics alone. There's quite a lot of clever ways to control for environmental factors, like twin studies. And I simply think you're not engaging in good faith whatsoever if you don't see how that Nature article creates a huge chilling effect on any discussion of genetics.
Right, and it only needs to be right often enough that taking the time to ask it is positive EV. In practice, with the Linux kernel, it's more or less consistently right (I've noticed it's less right about other big open source codebases, which checks out, because there's a huge written record of kernel development for it to draw on).

Excellent idea. With de-anonymized voting, the not at all corrupt, totally non-violent ruling regime would never take advantage of the added ability to know and threaten specific people who voted for the opposition.

As should be obvious, anonymous voting may be far from perfect if other parts of the electoral process are deeply rigged, but it at least prevents the blatant dangers of being personally afraid to even cast a vote against the leader even if you know your vote might get papered over with electoral rigging.

A government like Venezuela's wouldn't care if that level of transparency made their vote counts look like even more obvious frauds. Its electoral victories already look bad and it doesn't stop anything they do. But at least they can't tacitly coerce voters into not even casting the "wrong" vote.

I'm not sure this really addresses GP's question, which I share.

You claimed in GGP that deciding whether a function is total is a TFNP problem. In particular, that would make it decidable. But the counter-claim is that deciding whether a function is total is actually an undecidable problem.

I've also examined a definition of TFNP and I don't see how it is related to the problem of deciding if a function is total. Rather, the definition seems to require that the function in question be total.
The idea of introducing robotics to farming is very attractive. It doesn't seem like this is a scalable solution for farming, but a sufficient one for gardening.

They started this project a decade ago. But robotics has advanced quite a bit in that time. Surely, today it is much more viable to have four wheeled robots watering, weeding etc at the same precision this product can. Then why build a gantry.
Not just cloud providers, they’re being baked into enterprise & consumer hardware and software.

I dislike the trend of AI being used as a search engine on the public internet, because of the dubious results. But as internal search engines (e.g. for corporate networks) they’re better than the current offerings (which is admittedly a low bar).

Also in the southeast, and it should be pretty easy to find someone to come and bail your hay for you and take a percentage of the hay for themselves. I believe we do 9 acres, and get two harvests. After splitting it with the bailer that's still enough to feed about 25 head of cattle through the year. Though we do supplement with some feed for nutrition reasons. (Our Nutrition, not the cows, we eat them). Late in season the bailers will also typically bring us free hay too because they will cut some fields and have extra. You would still likely need a tractor to move the hay though but you might could figure something out with a trailer. Look for the market bulletin in your area if you haven't already subscribed.

> The key detail here is that the bumps grow exponentially smaller

Pedantically, it's that the bumps grow exponentially narrower.

IIUC, a simpler (but more nitpickable) version would be f'(n+1/y) = [the fraction of n-state Turing machines that halt within y steps] (for positive integers n, and 0 elsewhere); then f is the integral of f'. The value of f(x) can be approximated arbitrarily well by running every floor(x)-state Turing machine for a large finite number of steps[2], but f'(x) is equal to Chaitin's constant[0] for n-state Turing machines over a strictly-positive-length[1] subinterval of [n,n+1).

A much simpler version is f'(x) = {-1 if x<0; +1 if x>0; Chaitin's constant if x=0}. f(x) = abs(x).

Basically, this isn't even a parlor trick. It's a nothing burger, disguised as something by means of a parlor trick.

1: ban new housing from being built

2: a supply shortage develops

3: prices rise, and we don't build more housing

I think the tax policy is prop 13, which is a handout to rich homewoners that means they will never sell their houses (very nice for them, not so for anyone trying to get new housing)
My first thought was exactly this. How reliable can it be to run autonomously and how long before parts start breaking down.

You’ve got a point! There was a special moment there for a while. Your description perfectly captures my experience interning on a small IT team around 2000. This was in England so the secretaries would snigger whenever I said “debugger”. The downside was that the management had absolutely no clue about software as they’d jumped from some other career and the field was advancing quickly.
At about $110k for 8000 daily calories, you might as well just wait for android robots to be capable of farming and then buy one from a company like Figure, though you'd then have to worry about it getting hacked and trying to knife you in your sleep.

Looking at the pricing and the area the robot covers, isn't it too expensive?

Free housing doesn’t address the root cause of the mental illnesses and homelessness. In my very expensive city they do offer free housing but the occupants remain drug addicts and petty criminals.

>Otoh, certain products like TVs do seem to get better and cheaper as time goes on, yet people don’t seem to delay purchases. It’ll be interesting to see if conventional wisdom about deflation holds, should it come to pass.

The problem isn't just the osborne effect, it's that deflation rewards a non-productive investment (money hoarding) that crowds out productive investments, which makes the economy less efficient.

Buying a TV comes out of spending money rather than savings/investment, and is harder to evaluate because if TVs are getting better and cheaper in the future, they're getting better and cheaper now and so people have more reason to upgrade in the first place - which offsets the incentive to delay the upgrade for future benefits.
It's remarkably simple (to me, at least)

>moving logic

Oops typo that "logic" isnt supposed to be there.

I meant that its the simplest "complete" system that includes power, memory, i/o, tight integration with software (ie "bitstream format"), etc.

If you already have tooling in place to fabricate logic gates systematically, it's almost trivial to go up to XC2064 level of complexity; you might even want to do that before optimizing your "revolutionary" logic gates. Okay this might again be obvious, but it's exciting, motivational, calming to point that out to "beginners" (often that's what revolutionaries are), who want to know at every step that something close to their API has been mostly validated & they can concentrate on the revolutionary kernel

Your points are largely valid and there are many examples of mobile robust at scale autonomous robot vehicles for "big farms" today, it's still a growing market domain with much innovation.

> Then why build a gantry.

Part of at scale agriculture is growing seedlings (fruit trees, etc), conducting ANOVA trials (small plots to test many seed varieties).

There's a good chunk of "big agriculture" taking place in warehouse sized greenhouses with roller topped tables, big sliding trays, tightly packed young plants, overhead gantries for cameras | sprays | lifting hooks, etc.

That's a future I would love to see, even though it's way less efficient than industrial farming.
