"Knowing" for me means, that there is no way, that we can be wrong about something. Otherwise it's only "believe", not "knowledge".

It would be good to say the following, instead of "it is so": "So far experiments did never show any sign of identity of photons." (Were there any such experiments?) Oh and what about quantum entanglement of photons? Could that not be interpreted as a sign of identity?

I don't agree, but I don't want to act as an outstanding coder. I don't even want to defend AirVPN developers because their software "Eddie" for Linux is ugly, IMHO, and I say it as an AirVPN customer too. But hey I hate Mono. :)

But the OpenVPN 3 fork and Hummingbird too appear to me as good, very good. The fork is well organized, the new parts are quite elegantly coded at least to me, very readable and well commented, and it's kept ahead in alignment with the main branch. Some time ago I also followed AirVPN commits to the main branch and after I took my time to watch the code I was astonished that they were rejected with some arguments that, I think, are either pretentious or wrong, but that's an opinion of mine, the facts can be seen by anyone looking at the code and some smart solutions/implementations I find delicious such as pointers to methods to optimize and save time in packets cipher dependent decisions. I wonder... if the initial commits to the main branch were not rejected, would AirVPN have forked? They forked only after a long debate... I don't know but...

We're in a huge pickle in general because every simple, effective drug gets blacklisted pretty quickly, because people realize there's a simple, effective option for treatment that doesn't make them dependent on our horrifically broken medical system and start buying it without funneling through the racket. This upsets the racketeers and they work to clamp down on it.

In the rare case where a simple, effective drug gets into medical practice, it magically ends up becoming "not recommended" about 20 years after it hits the market when the pharmaceutical company's patent runs out.

MAOIs work much better for depression than SSRIs, for example, yet the clock runs down, a few widely-publicized cases of serotonin syndrome caused by careless ER doctors hit the press, and suddenly anyone prescribing those drugs comes under scrutiny, and we all need to switch to the newly-patented option.
Thanks for posting this. The tl;dr is:

> I don’t think the correct summary of the above study is: “A large effect was found. But this was a small study, it’s preliminary data, so let’s gather more information.” Rather, I think a better summary is: “The data showed no effect. A particular statistical analysis of these data seemed to show a large effect, but that was a mistake. Perhaps it’s still worth studying the problem because of other things we know about air pollution, in which case this particular study is irrelevant to the discussion.”

> The point is that these data, analyzed appropriately, do not show any clear effect. So if it’s a good idea to keep on with this, it’s in spite of, not because of these results.

This is so good! Gelman's comments on the study are a better HN post than this article.

This is important stuff - you can already see people researching air filters in other comments, taking the supposed results of this study as settled truth.

Increased CO2 levels in the air will reduce mental performance. I mean it isn't a ton unless you are seriously sealed up, and I don't know about particulates and other pollution. But a poorly ventilated room can have CO2 level rise double that of a well ventilated room and has been measured both in actual rooms and building CO2 levels and with subjects being tested for mental performance under experimental conditions with controlled CO2 levels.

Looks like they've taken Too Much Crypto to heart[1] and dropped the number of rounds from Blake2B's 12 down to 7 for Blake3:

https://github.com/BLAKE3-team/BLAKE3/blob/master/reference_...

https://github.com/BLAKE2/BLAKE2/blob/master/ref/blake2b-ref...

Which, yeah, that alone will get you a significant improvement over Blake2B. But definitely doesn't account for the huge improvement they're showing. Most of that is the ability to take advantage of AVX512 parallelism, I think. The difference will be more incremental on AVX2-only amd64 or other platforms, I think.

[1]: Well, TMC recommended 8 rounds for Blake2B and 7 for Blake2S.

The difference between using natural gas and any other hydrocarbon fuel is pretty much neutral.

But overall hydrocarbon use is continually increasing, due to the underlying problem which is also the same underlying problem for most of the world's other problems.

And that underlying problem is the World's ever-increasing population growth. It's pointless trying to reduce carbon emissions if we don't also try to maintain a constant population or even reduce that population at the same time. Because the emissions-increase due to population-increase will swamp all of your hard-fought emissions-reductions.

The Chinese went in the right direction with their "One Child per Couple" policies, but a better step would be to introduce a "One Child per Woman" policy world-wide.

Over the course of about several generations, the World's population would drop about 50% without any kind of "deliberate-killoff" apocalypse.
The environmental benefit would ultimately be in reducing car trips and allowing cities to once more be built human scale, enabled by scooter-transit-scooter trips (scooters solve the last mile problem).

Unlike Erlang which copies messages, and Pony which uses reference capabilities, BeAPI used a pragmatic approach where BMessages shared a kernel memory pool. Add the ability to filter messages and dynamically retarget messages, and you get a PRACTICAL (vs academic) Actor model. I wouldn't say it was half-hearted and primitive, on the contrary.
Typically, knowing the mechanism comes long after solid evidence of the effect.

The mechanisms by which cigarettes cause lung cancer are surprisingly complex and weren't fully understood for a long time, but it's obvious that some kind of mechanism is plausible.

So usually the bar for taking something seriously is: statistical evidence of a significant harmful effect, and at least one plausible hypothesis for a mechanism. But you don't have to be sure of the mechanism.

> In many areas this would effectively lead to the suburbs being able to dictate urban policy to the inner city

Then perhaps "urban policy" is an unnatural category, combining conflicting interests.

Why not just have two municipal governments—one elected by those whose business interests lie within the city, which would be in charge of the city's business policy (e.g. corporate taxe and grants, arterial infrastructure, commercial zoning); and a separate one, elected by the city's urban residents, which would be in charge of the city's civic policy (e.g. estate taxes and VATs, non-arterial infrastructure, residential zoning, etc.)? These are essentially orthogonal problems that don't really "run into" each-other much; you could have two separate sets of people working on solving them without those groups needing to communicate all that much.

Municipal government is already somewhat factored this way, insofar as e.g. school boards and park boards are separately elected rather than being appointments of the municipal executive; and some of those elections are defined by different political boundaries (e.g. catchment areas for schools) than the election of the municipal executive is. Why not just go one step further?
I think it would be hard to compare the two times. Canada is unrecognizable in so many ways when compared with Canada before that point in time. We got a constitution, no-fault divorce, and a whole lot of other major changes in the course of about ten years, the same ten years the provincial health insurance was introduced AFAIK.

> which would make it the oldest surviving manuscript of the New Testament, copied less than 30 years after Mark had actually written it.

I'm amazed at the fact that more people don't push mostly static or rarely updated data to local sqlite instances or flat files.

In my line of work, the goverment distributes a daily file with all those tax ids that can emit tax deductible invoices. Since it has every tax id along with additional information, the file is quite large (30Gb of XML split into 4 files because of the format). This file has to be downloaded and used daily by all our front end servers.

Every Engineer immediately proposed throwing the data on the Galera cluster that we're currently running. They didn't see the problem of slowing down the main database every day with a huge update cycle (you could diff it previously but it's still a large update). We'd also be querying a network storage for basically static data, which I thought idiotic.

I proposed having a simple daily task in a job server that downloads the data, parses it and writes it to a sqlite database. It then pushes this file to all of our frontend servers. The frontend servers simply reference that file. It's a lot faster, especially since the whole thing can fit in memory when its compressed binary data (drops down to about 12G), and you simplify your reads.

I completely agree with the statement made by the author too:

"Aside from the quirk of sharing SQLite across containers, it delivers extremely well on one core idea: the thematic shift of complexity from the data plane read path to the control plane write path."
Indeed, often the needs of the experienced person are quite different from the needs of the “tyro”. So even though I often disagree with consumer reports on, say, laptops, the very reasons I disagree made me confident when buying a toaster oven or glucose meter.
The article explains why the air filters were installed, and it doesn't fit your supposition.
Now it does, but it might not be this way in the future. Health insurance companies fought tooth and nail about covering pre-existing conditions. This is just going 1-step prior.

They could easily frame this as "hey 80% of the population who are pretty healthy -- do you like paying extra high rates for this small population of people with a predisposition for really rare, complicated diseases? if we drop this unfair law we could lower your rates by X%".

Not saying it's right or ethical, but that I wouldn't be shocked if healthcare started lobbying hard to get this tweaked.

The second notion, where it's clear that the memory space can safely be used, is why there's interest in linear and affine type systems. These systems describe types whose value can only be read one time, and for linear types, which must be read one time.

On the surface that can seem a bit stupid, but the practical outcome is that compilers can determine when an array's contents can be mutated in place rather than overwritten.

A variable you read over and over can be thought of theoretically as one you duplicate, then read one copy of. Since the act of reading the copy destroys it, a compiler implements this by merely reading the value directly.

Passing an array into a subroutine however means the compiler either copies it, or forbids further access after passing it in. If it's the latter, the memory space is available for re-use inside the subroutine.

Rust uses affine type theory for its borrow system to provide memory safety. Function language research is looking at linear and affine types for a variety of applications including performance.

It does if you want research done so compilers can implement results in this space and optimise away unnecessary copies without introducing errors.

>How many things were invented or financed because someone wanted to get rich?

Not as many as you think I would suggest. In the US a golden era of invention was the postwar era during which inequality fell and the American middle class rose to power and the American government still participated actively in shaping innovation and economic future. Even the Soviet Union invented a good deal of stuff.

Today economic growth is low, inequality is high, it looks like we're on our way to a second gilded age and the things that we call innovation are escooter startups and expensive juice machines. Even die-hard capitalists like Thiel have pointed this out.

If you want innovation what you need is a healthy, equal society, individual opportunity and collective ambition.
