That seems a bit harsh. You have to start somewhere, and this teaches basic stuff like an ALU, Clock, Accumulator, etc. Some homebrew CPUs have memory bank switching.

Moving to an FPGA based CPU might be the next step. There are soft CPUs with cache, MMU, etc. (https://github.com/SpinalHDL/VexRiscv for example)

I thought about including this since I saw a talk about it once where the guy referenced Clojure, but they don't talk about Clojure at all in the README.md.

British Medical Journal? Impact factor 27.604 in 2018. But in scientific publishing the intended audience is not lay people. You really have to know how to read the articles to determine what they mean. I liked their series of articles called "How to Read a Paper."[0] But keep in mind [1].

Not saying you're wrong, but if your reason for commenting was to convince someone you're right, you probably ended up failing that.

Emergent Logic
I just read an essay about Minds, Machines and Godel.
https://pdfs.semanticscholar.org/bde3/b731bf73ef6052e34c4465e57718c03b13f8.pdf

I hold the somewhat rare opinion that Consciousness and
Intelligence in humans are "emergent properties", similar
to a traffic jam as an emergent property of cars and roads.

I am also of the opinion that this "emergent mind" does not
follow any known logic but has its own "emergent logic".

By analogy, cars logically can go from one place to another
without stopping but traffic jams can cause a car to stop
even though the road ahead and behind are still flowing.

Emergent rules do not follow from the substrate rules.

Emergent properties arise from complexity. I am of the
opinion that the difference between an intelligent animal
such as a monkey and a human is directly related to the
complexity of brain structure. Since intelligence is assumed
to emerge from complexity. The "logic" (bad word) of each
is of "a different order", somewhat like the difference between
a car traffic jam and a bicycle traffic jam.

What this "emergent logic" is, though, I cannot say.

The closest I have come is by analogy to chaos theory.
Nonlinear equations can exhibit states that never repeat
from very simple nonlinear equations. Current "logics"
seem "linear" to me and thus cannot be chaotic.
I think it's likely to be a product of internal incentives and how these create a culture. I would be prepared to wager than it's much easier to get a promotion by working on a new hot thing than on maintaining or improving an existing thing.

Scroll forward a couple of years and you have a reputation for just abandoning existing things rather than improving them, because people individually maximise their own career advancement by migrating off difficult maintenance and improvement projects on to "new hotness" projects only to abandon them again later for an "even newer hotness".

Small organizations have an immune system that rejects bullshit like that but as orgs grow they institutionalize and it becomes harder and harder for them not to succumb.
I wasn't talking about the speakers, but the head-unit itself. This is often not just a radio, but an integrated unit with display, controls etc for navigation, radio, HVAC etc.

In just about any car produced >2000 these radios are integrated in the dashboard, thus not easily replaceable.
Assuming it's the BMJ that I know of that's the 'British Medical Journal' which is highly regarded.

There is a path to a kind
of logic that seems to be well-defined but chaotic.

The connection seems to be thru Homotopy Type Theory (HOTT)
If we look at HoTT we find a mapping between logic to topology.

There is work at CMU by Kristina Sojakova
http://reports-archive.adm.cs.cmu.edu/anon/2015/CMU-CS-15-10...
using logic to prove the equivalence S^1 x S^2 = T^2
(S^1 is a circle, T^2 is a torus)

There is work on the relationship between the torus and
Stephen Smale's work on strange attractors
https://link.springer.com/content/pdf/10.1007/s00209-014-138...

Strange attractors show a natural fractal character for some
initial values, leading to chaotic behavior on the torus.
https://en.wikipedia.org/wiki/Attractor

It should be possible to develop a logic based on a torus
that was sound but leads to chaotic behavior. That would
certainly form a basis for "nonlinear logic".

My claim would be that a "nonlinear logic", aka chaotic
logic, would be a "higher order logic". In that higher order
logic we would find "emergent behavior" which is the kind
of behavior that is unpredictable but sound.

Mapping from chaotic functions on a torus to a supporting
logic would escape deductive logic, and likely provide a logic that
is not covered by Godel.

The chaotic behavior is sensitive to starting values where
values differing by epsilon could be stable or chaotic, I'm not
sure how to capture this notion of "nearby values" in a logic.

Note that chaotic values don't diverge to infinity but remain
"within the logic" but never achieve what might likely be
called a "fixed point".

Depends what happened to their compensation and stake in the company (hopefully nothing); in that state it's harmful to both parties to keep the CEO responsibility on someone who's going through that much.
Interesting! Anecdotally I used to get very, very bad respiratory infections once a year when working in an office full time, getting at best an hour in the sun a day. Now I remote work and get anywhere from 2-6 hours sun most days, and I haven't had a serious infection for more than a year and a half. Could still be coming, but I feel 200% better overall so regardless, highly recommend getting outside more.

Edit: maybe this came off as a humble brag? Getting a downvote or two, which I don't mind, but I wouldn't want to give off the wrong impression. I only work from home, I am not a jetsetting nomad, I can just work around my outdoor activities now.
I switched to DuckDuckgo a few months ago, and never looked back. The results used to be far inferior to Google's - but they seem to have caught up recently. If you haven't tried them out within the last couple of months, I strongly recommend that you give them a chance.
ripgrep doesn't require memory maps, and if they fail to open, it will fall back to a more traditional buffering strategy: https://github.com/BurntSushi/ripgrep/blob/50d2047ae2c0ce2ed...

ripgrep has always had a fast traditional buffering strategy using `read` calls for searching, because I knew that mmap couldn't be used in every case.

Anyway, this has been fixed for a couple years at this point, so if you're still experiencing a problem, then please file a new bug report.

> As a more recent example, ripgrep had issues on 32-bit platforms because of a bug in the way the underlying mmap library worked in Rust.

This is false. The bug you're thinking about is probably https://github.com/BurntSushi/ripgrep/issues/922, which was not caused by an underlying bug in memmap. memmap did have an underlying bug with respect to file offsets, but ripgrep did not use the file offset API. The bug was caused in ripgrep itself, since I made the classic mistake of trying to predict whether an mmap call would fail instead of just trying mmap itself. That bug was fixed on master before the Windows bug was even reported: https://github.com/BurntSushi/ripgrep/commit/93943793c314e05...

> You'd only try that if you haven't read the documentation for mmap, just like a bunch of Rust programmers did.

This isn't exclusive to Rust programmers. C tools make the same mistake all the time. Because memory maps aren't just problematic with large files on 32-bit systems, but they also don't work with virtual files on Linux. Try, for example, `ag MHz /proc/cpuinfo` and see what you get. Crazy how, you know, sometimes humans make mistakes even if they are a C programmer!

And the implication that I (or the author of memmap) never read the docs for `mmap` is just absurd.

If you're going to be snooty about stuff like this, then at least get the story correct. Or better yet, don't be snooty at all.
> It's true that I don't lend credibility to supernatural hypotheses, which I'm sure isn't the most popular position to have, I understand that. However, given the fact that everything we can actually observe so far seems to follow natural laws, I posit that the burden of proof is on the dualists to show me something that cannot possibly work without supernatural invention (or, preferrably, directly demonstrate such intervention).

I'm not sure what you are defining as 'supernatural' but 'everything that isn't observable' seems like an exceptionally poor definition. Throughout history there have been plenty of unobservable forces which nonetheless turned out to exist. Even today, our scientific knowledge is such a minuscule fraction of the universe; the number of unknown-unknowns is perhaps infinite. Even something like dark matter is still a known-unknown. To make broad statements like "reality/cells are just machines" based on this tiny portion of information seems pretty foolish.

The flaws of your position are shown quite well in the "Blind men and the elephant" proverb.

> Adam built a massive following...

say no more. that was my first thought. online popularity is a real thing and most people tend to ignore that.

i want to say it's less about what you are building but the number of people you can convince. the result of years of online socializing...

in fact, i have been, sometimes, utterly impressed by people who build large followings and supporters on patreon. having people believe in them while they are still figuring out their journey.

and on the other hand, i have seen i have seen people i have admired for years and considered role models try to build an online following and fail.

Because philosophy can't itself prove all truths (Godel incompleteness), we must accept that the point of philosophy is better living.

Once that is in place, philosophy can become much more valuable.
Does Clojure actually force you to use those abstractions though? Many languages provide concurrency primitives, but Rust will fail to compile if you try to use non-concurrency safe objects from multiple threads.
I wonder if selecting your population via people who respond to a Facebook ad about studying quitting social media introduces any bias. (I can't see the article so I don't know what their ad actually was) I worry that the correct takeaway is people who are interested in the idea of taking a break from social media probably should. Maybe the study was sufficiently well compensated that people who feel positively about social media still felt participation was worthwhile?
I never understood the value of Twitter. It looked to me like a few people machine gun blasting personal details to the world. Why anybody would do that or even read it was bizarre to me. I guess some people just crave attention.
Talk about your empty calories
Facebook, like many other things in our society, is a Clan-thing. "My clan vs your clan" is a game that humans play very very well.
Their initial reaction is just "oh, you are not one of us". If you talk about the details, they might agree with you, but they still fall for the "not one of my clan"-thing initially.
Same happens with many things.
Linux vs Windows vs Mac OS
Android vs iOS
Left vs Right
Vegetarian vs meat-eater
vaxxination vs anti-vaxx

Unfortunately I can't find the source, but I read somewhere that it wasn't proven that Vitamin D supplements can improve outcomes after infection has occurred. Can anyone find the source on this and verify?
Hacker News has gone from the anger to the bargaining phase of grief. 4chan, ahead of the curve naturally, is currently in full blown depression phase.
Indeed the firewall at old-fashioned newspapers (between editorial and advert sales) was vital to their independence and dissolving this (today you can buy "native advertising" which only the most careful reader will realise isn't editorial) has been part of their downfall. You actively want the people who write the stories to be shielded from whatever the people making money to pay for those stories do. Every time a journalist even feels like they shouldn't write a story because it'll lose their paper (or TV channel, or website) money that's a problem.

That doesn't mean the media aren't worth criticising, but it means you should aim for it to be possible for that critique to come from within.

Funding models other than advertising are good, but they're not realistic for very broad media. I might give money to a person who writes (or talks or makes videos) about a subject I care very deeply about, but who is going to give money to the people doing a morning breakfast show or a mid-size city newspaper? Those things are expensive and advertising remains a realistic way to fund them.
It's Google. They seem to have hundreds or even thousands of edge data centers all over the world, and it's plausible they'd put Stadia servers into all of them. Which means that a decent fraction of the population will have ping times that are much lower.

What’s the connection between calcium and D?

I recall someone telling me you had to be careful of supplementing D or you could promote calcification in arteries. You had to take with a calcium shop or something. Is that true?
Sounds like your exposure to other people might have changed dramatically: working in an office full time -> remote work.
The Davy reference was a bit aggressive, I must confess. The early ways of making magnesium metal would have worked on a lab scale, and would have been frightfully expensive. Practical Mg production had to wait for the large scale production of electric power for electrolysis, or for the production of silicon (in electric arc furnaces) for the Pidgeon process. Still, magnesium was being produced in large quantities by WW 1, if not before.
Them and how going to Chinese market is a fair example.
Table 4:

> When all studies were analysed together, no statistically significant effect of vitamin D was seen on the proportion of participants with at least one upper respiratory tract infection, lower respiratory tract infection, hospital admission or emergency department attendance for acute respiratory tract infection, course of antimicrobials for acute respiratory tract infection, or absence from work or school due to acute respiratory tract infection. However, when this analysis was stratified by dosing frequency, a borderline statistically significant protective effect of daily or weekly vitamin D supplementation against upper respiratory tract infection was seen (adjusted odds ratio 0.88, 0.78 to 1.00; 4483 participants in 11 studies, P=0.05; table 5⇓).

Which to me makes it sound like it makes almost no difference.

Edit: The above could be for pre-exsisting patients.
I've been wondering why it is that virus infections are supposed to "disappear" in the summer. Obviously the viruses don't actually go anywhere, so I would expect people to get sick year round. Maybe immunity boosting from Vitamin D could be part of the answer.
Don't underestimate the difference in scale between Google's network and whatever powers the other streaming services...

I'm bearish on streaming games as well, but if there's one company that has the potential and know-how to solve the hard problems, it's Google.
Weird, my mom doesn't understands it either.

Although there concept is simple: your phone is the remote, you need to connect to the TV. The app you would normally play it on, shares it to the TV.

Yes, and I'd say his following was earned and his methods can be copied... they're just a lot of work and take time.

The quality of his work has definitely been a key factor, too.
Not surprising. I don't feel Google is setup to be a platform business (even though that's a lot of what they do!).
Employee mindset isn't on keeping a platform running or improving but instead chasing the next-best-thing.

That's how you end up with x programming languages, y services and 1000 messaging/chat apps.
> Maybe the reductionists are getting closer and closer to reality, the more powerful the metaphors become?

Assuming technology progresses toward gaining more knowledge of the universe, then this would be the case. However that doesn't mean they are actually accurate metaphors, merely that they are slightly better than ones before them. 1% is a hundred times more than 0.01%, but it's still just 1%.
Pish. It's mostly based on an article by Thomas Piketty, which is linked.

Piketty may be many things, but right wing is not one of them.
Ask HN: How do you search for $string if a webpage “supports” infinite scroll?
Let's say you visit a webpage like Reddit and want to search for $string. Maybe I am too stupid, but in my opinion it's just not possible anymore. :( Content is dynamically loaded in and out and you have to scroll carefully not to miss a $string when using browser based CTRL-F. That is just ridiculous.

For me infinite-scroll is one of the most stupid features of the "modern" web. It just makes the experience worse to crank up some dubious engagement numbers.

And to make it clear: I don't want to search for stuff via $string site:reddit.com via some search engine. Often I really want to search for exact $string on a page, but on something like Reddit that does not work anymore.

[/rant]

EDIT: Thanks for all the answers. And I think I hit a nerve here :) Maybe it makes some frontend developers take a step back and really think if it's really a good idea to implement that "feature".

As suggested you can use old.reddit.com in case of Reddit, but for some pages, there just isn't an option and the worst offenders even hijack your CTRL-F and want you to use their own terrible search.
Glad to read that I was not the only one struggling with this. It reminded me of that [jargon is bad study](https://www.sciencedaily.com/releases/2020/02/200212084357.h...) that came out recently.
In your case avoiding the office is more likely to reduce your infections than the sun.
How do you pronounce that?
Touching a virus doesn't guarantee you being infected. It can't penetrate skin. Inhaling a droplet of saliva that somebody coughed up is much worse.
But Google Analytics is typically (always?) done through JavaScript in the browser. And if the browser blocks any call to the Google analytics servers, Google won't know the user agent.
It's also amazing to me how quantitative, evolutionary advances to some technologies that might seem futile or superficial enable some qualitative technology leaps.

For example, miniaturization of computers seemed pretty futile to me in the 90s. Indeed, why would I care if that big box becomes slightly smaller?

That miniaturization is basically what enabled the whole smartphone industry. The large-scale availability of small and powerful chips in turn enabled the drone / quadcopter to become feasible (a quadcopter is too unstable to fly on its own, and there's no real way to stabilize it mechanically like we do on RC helicopters; it has to be stabilized electronically).

I think the best inventions come from recognizing the kind of qualitative leaps you can do from evolutionary advances to existing technologies.
Your test is basically asking “is it similar to something popular”, there will always be a learning curve when changing to a new, different from what you’re used to, tool. In my personal experience, I’ve seen people go from no Clojure or functional programming knowledge to productive in a few weeks, that’s quicker than I’ve seen some people go from non-OO to OO (although I imagine it has more to do with the people than with the paradigms)
Can you provide more detail?
Usually grants/projects etc in research in Europe explicitly budget "overheads" as a separate budget line. The size ove the overhead varies between the different funding instruments, but are usually between 20% and 100% of the direct costs (mostly wages). Universities will have internal regimes that distribute the overheads between the central administration, for covering such things as office space, heating, shared services etc., and the research group in which the research takes place for covering computing, office supplies, local admin, travels, publication consumables etc.

So for example a 2 year project that has 120K allocated in direct cost salary, with a 75% overhead regime in a university with a 25% central overhead take would have an overall budget of 210K of which 120K would end up payed as salary to the researchers, 52.5K taken by central administration, and 37.5K taken by the research group.

While technically you could argue paying researchers more would also net the university more money, asthe overheads are calculated as a % on direct costs, in reality this does not hold as funding for research is very finite and funding agencies would not approve paying higher project grants.

Both universities and large businesses have been successfully lobbying for years for higher overhead % regimes in grant instruments, and since the budget for funding research has not changed in line with these evolutions, defaco shifting the windfalls of research grants from the researcher's wages to the administrations.
YouTube channels that uncover the latest and coolest developments in ML
In my experience it can work quite well. I work alone on many projects. Given, you need support staff. I have someone to document everything aside from the most technical parts that I need to write myself. Also a project manager that extracts requirements and expectations from customers. Doing that myself would increase project duration tremendously.

It is pretty common in the embedded world in smaller companies. There just aren't enough developers to render enough support.

The problem with one-man-shows is the dependability. A lot of web developers go that route. But if they are unavailable because of private stuff or illness, the project they are working on is basically iced.
Vitamin D has a significant role in calcium homeostasis and metabolism. Its discovery was due to effort to find the dietary substance lacking in children with rickets (the childhood form of osteomalacia).[12] Vitamin D supplements are given to treat or to prevent osteomalacia and rickets.
