My answer was to Dr."(Astrophysist [sic] here)" saying "This is complete BS."

If the previous relativistic models failed to produce results different from Newtonian gravity, it was, apparently, because they were wrong. Now, I don't claim to know anything about how to simplify GR solutions, but I know of people whose job it is to be able to simplify GR solutions correctly; and to be able to tell whether they have been simplified correctly. If they are getting that part of their job wrong, what reason do we have to believe they are doing the rest of their job any better?

Even if simplifying the maths is too hard for most of them, some one or other might have thought to run a direct numerical simulation, without any simplification. (Maybe have an undergrad do it? Or, every undergrad?)
It varies on the individual, probably due to body mass and so on. Even then, it's not like a certain dose will guarantee a certain experience. I'm a ~72kg man and I'd say 3.5g is a normal dose and 4.5g is verging on high. The most I ever had was around 5g.

The two truly profound spiritual experiences I've had were actually 22g "High Hawaiian" magic truffles (not mushrooms, but similar), and around 5g cubensis magic mushrooms, though I did eyeball it so it may have been more or less.
Yeah, absolutely; wasn't criticizing the choice of FreeBSD more generally (short of elegant maybe, but the only real UNIX systems available these days are illumos and xv6, and they're short of elegant, too), just thought it odd for that specific use case.

Thanks for answering! That's really interesting about clisp; I've always found it a more comfortable interactive environment than any other Common Lisp, but it definitely sacrifices portability for comfort in more ways than one (lots of symbols out of the box that aren't in the HyperSpec or any other implementation, too, for example). I'm now really thankful I've never been tempted to look to its source!
For what it's worth, that's never been USPS's motto or policy.

Assuming Canonical would eventually cease to exist or discontinue Ubuntu Core, it would be nearly impossible with Ubuntu Core for the open-source community to ensure that NextBox would continue to be usable in a meaningful way.

It's about more than the monetary costs over the coming couple of years. Canonical pulling a RedHat here would be much worse for Ubuntu Core users than it is/was for CentOS users.
So weird. Why would you hold something without any plan to sell it, nor a thought towards using it?
I worked at a radio station and would do this sometimes with a tape deck (Revox) that could record and playback at the same time. Was always fun to trip up the presenters, it's almost impossible to talk that way.

I'd never do it on the air by the way, I'd use an aux bus while taking to them over the TalkBack while music was playing.

>To me, these vaccines have been as rigorously tested as they could be

Not for me. The fact is, the vaccines have been pushed through faster than any vaccine before. Anything foreign entering the body should be tested and based on solid evidence. Doesn't matter if it's an artificial heart, stent, prosthetic, or a biological agent like a vaccine. If decades of medical research shows determining a vaccine's safety takes years because of ethical protocols, then it takes years. The present vaccination campaigns are performing more comprehensive stage 3 trials on the general population because the risks are deemed acceptable. As other people have said in this thread, a person under the age of 18 is 50% more likely to die of SARS-CoV-2 vaccine complications than from SARS-CoV-2. The risk isn't worth it at this time.

Additionally, the technologies being used for the vaccines is still deemed experimental, specifically the mRNA ones. No mRNA vaccines have been deployed before, but now it's being deployed on the general population without public knowledge of any potential risks of this unproven technology ("unproven" meaning lacking a prior real-world deployment effort; a rocket engine is only proven when it flies, not in simulation). One risk with the mRNA vaccines is that they need to be kept extremely cold to preserve the mRNA sequences [1]. If the dose warms, good mRNA sequences break down into junk mRNA, which for all intents and purposes are random nucleotide chains. That ties into an above point: no rational person wants random mRNA pieces put into their body. Again, while all risk is relative, for my age group, the risk is not enough.

If you're well-versed in the science, I recommend reading this complaint [2] filed with the EU regarding Pfizer trial safety.

All current astrophysics is “proven” in a sense that bunch of scientists loosely agreed that strange unexplained things we see explained as such, but then there are elephants in the room like dark energy, dark matter and etc. So it’s really far away from actually being iron-clad, unlike more basic QM or GR.

I think that plan may have been axed, as (anecdotally) the number of communal mailboxes seems to be relatively low among the few cities I've visited/lived in over the past couple of years. Also anecdotally, I'm not sure why the majority of houses (in the burbs) seem to have a mailbox by the door or a mail slot instead of box by the curb. They definitely exist, but feel like a minority outside of rural areas.

That's a very interesting and well-done experiment! I definitely learned something -- and I buy the argument that there is a way to tie a figure 8 that makes it less likely or significantly less likely to be difficult to untie ...

But I think that as rope wears and as humidity goes up -- you'll still easily find situations where the knot was correctly tied but still a lot of effort to untie after load ...

And 12-18 seconds to untie is still a lot more time required than untie'ing the double bowline ... And he's showing figure 8 on a bite so he doesn't have to take the extra seconds to undo the figure 8 after ... that's not a huge deal but the double bowline is still imo easier to tie, faster to tie, and faster/more ergonomic to untie -- and also of course, harder to verify that it was tied safely by visual inspection ...

> Bare metal management really feels like an unsolved problem. Whilst everybody working with cloud environments is whisked away by the latest shiny tools like Docker and Ansible, those of us working with bare metal are still trying to find a way to keep machines up and running with an OS that doesn't get corrupted from unexpected poweroffs or permanently cut itself off from the network because of a bad config.

It is and isn't solved. It usually takes a lot of work or custom scripts. One of the best is the Nerves Project, and is what I use for IoT deploymens [0] or even simple cloud deployments.

Nerves is setup to run Elixir/Erlang, but it's really just a wrapper around buildroot and Elixir can start programs in any language desired with some work. One of the core authors wrote a tool called `fwup` for doing immutable updates on Linux [1]. The ability to do an A/B update and have the device do an automatic rollback if an update fails is crucial.

A year or so ago they changed the default boot process to still allow networking and remote connections to work even if the main application crashes. Surprisingly it's all done using Erlang tooling, AFAICT. There are still rough edges, like limited ipv6 support. You can still get devices failing from dead SD cards -- even if your system boots from a read-only partition as power outages during a write on any partition can effectively destroy the SD card, so skip the SD cards.

Yeah I'm sure dispensary licensing, county-level prohibitions, as well as growers licensing is all sorts of messed up. Every state seems to be caught in some kind of greedy protectionist cronyism in that regard, and this won't be fixed unless the federal government legalizes.

States are also not equipped to have an FDA level of review to create studies.

But outside of the west-coast, a lot of states seem to have less-blanked recreational legalization, like they legalize some molecular compounds while prohibiting others and certain strains.

Would definitely like to see standardization and just simply treating this stuff as any drug that comes with normal disclaimers and lists of side effects. I just hate all the anecdotes right now.

The bowline is very useful, and there are several ways to tie it, depending on the thickness of the line.

I set NoScript to disallow all JavaScript by default and whitelist those that I "trust" as I go, I have been doing that for a few years now.

The friction in surfing doesn't get lower over time, not least because my exposure to most non-whitelisted websites are through websites like HN, but it's also not high enough that I would consider not blocking JavaScript by default.

Websites that use a lot of third-party JavaScript are red flags to me; more often than not, they are unrelated to critical functionalities (such as payment), and they add absolutely no value to the client.

Perhaps one thing that is worth noting is that modern frameworks that are SSG-focused or hybrids like Next.js make developing websites for JavaScript-blocking clients a bit easier. I haven't personally looked into this too closely, but at least with the website projects that I have work on with Next.js, you would still get a presentable bare-minimum with little effort when JavaScript is turned off, it's also not difficult to implement a reasonable fallback for JavaScript-blocking clients.

The above of course depends on how much server data need to be fetched dynamically to render a page, which again depends on the nature of the content on a website. If I'm not mistaken, there are functionalities that simply can't be implemented, or very impractical to implement, without JavaScript; in those cases the question of "making it work for that 0.2%" is probably moot.
The lesson from 1918 for public health is that if you lie to or mislead the public once, even if by accident, you have reduced credibility in the future and are less likely to have the public listen to you. The authorities didn't learn this lesson and instead misled the public for 2 months, then did a 180 and expected people to blindly listen to them again.

As a citizen, would you trust the government if they did yet another 180, after demonstrating to you 2x that they didn't actually know what they were talking about?

Captcha mis-identifying a mailbox as a parking meter
I've been working on the dark mode implementation for Atlassian for the last year and a half, so this is right in my wheelhouse. This post is excellent advice for a small app, but if you have any production sized app or a larger team, it's not a great approach. Using colors directly in a theme override mean you have to then design and write the css for every page twice.

A better approach for doing dark mode is to use semantic tokens as a middleman. This works great not just for dark mode, but theming in general - allowing for high contrast mode, color blind modes, and others, while reducing the amount of effort required to style a new page (rather than growing multiplicatively with direct overrides).

If you're curious about this, I have a very basic schema I made for my app that you're welcome to steal here: https://github.com/jjcm/soci-frontend/blob/master/docs/token...

Here's an example implementation of the above schema: https://github.com/jjcm/soci-frontend/blob/master/soci-token...

The great thing is once it's implemented, it becomes VERY easy to know what token to use where. Got a button that's a primary action in a hover state? You probably want to use --brand-background-hover for the bg. Means you can do a lot of the design directly in code I find.
Reminds me of the bridge story in Margin Call [1]. Or if you'd rather read it, here's the script [2], just search for "Did you know I built a bridge once?". Or condensed:

"It went from Dilles Bottom, Ohio to Moundsville, West Virginia. It spanned nine hundred and 12 feet above the Ohio River. 12,000 people used this thing a day. And it cut out 35 miles of driving each way between Wheeling and New Martinsville. That's a combined 847,000 miles of driving a day. Or 25,410,000 miles a month. And 304,920,000 miles a year. Saved. Now I completed that project in 1986, that's twenty-two years ago. So over the life of that one bridge, that's 6,708,240,000 miles that haven't had to be driven. At, what, let's say fifty miles an hour. So that's, what, 134,165,800 hours, or 559,020 days. So that one little bridge has saved the people of those communities a combined 1,531 years of their lives not wasted in a fucking car. One thousand five hundred and thirty-one years."

I can't speak to enforcement of laws around psilocybin, but I can speak to federal enforcement of cannabis laws. I worked in the legal cannabis industry for several years. The claim that they are free to enforce it at any time is true, in the sense that any arcane law could be enforced because it's still law.

But it's not consistent with the federal government's posture since the first states legalized, even after Jeff Sessions led at least a vocal campaign to roll it back.

The reality is that the guiding legal principle that determines federal intervention in states' legal cannabis markets is the Cole Memo[1], and that all legal states operate comprehensive seed-to-sale tracking sufficiently satisfying that the federal government has either felt disinclined or disadvantaged to challenge it under the Interstate Commerce clause (which is how they can even ban drugs in the first place).

IANAL, but I'm very familiar with the specifics on the topic, and the comment above is full of misleading and downright bad legal advice.

This! The very cost of an interruption for the person who is interrupted is often under-evaluated.

It is very high form some types of activities and brains, and even higher if the interruption is raised (!) after a long work session, as the interrupted has to 'swap out his context' (what he was thinking), tackle the question, then 'swap in his previous context' before resuming.

You may think so but that's not the case. I don't know of too many vegan-organic-bike-riding-hippy types who think we shouldn't invest in grid-scale storage, renewable power, carbon capture, or more efficient heating & cooling, manufacturing, or transportation systems. Arguably the only tech many of them oppose is nuclear power.
That doesn't make any sense. All the "electrical infrastructure" needed to drive the typical 45 mile route is a regular old 120V exterior outlet. The retrofit cost is going to probably be double the marginal cost it would've been to just make it electric in the first place.

Whoever is making these decisions either wasn't given competitive bids or they're poorly informed about electric vehicles.
