This is such a difficult question -- I honestly wish I knew the answer outright and could give it to you.

I don't think I can do that much, but what I can do is offer some theories and context.

(Note: I wrote at length about this experience, and my general experiences with both psychedelics + MDMA here: https://news.ycombinator.com/item?id=22991744)

I'll write the following under the assumption that you/the reader don't have experience with psychedelics. There are some things you can put into words for those unfamiliar, and a great many other things you cannot.

---

Psychedelics are a fundamentally neutral substance. What I mean by that is, that they and the experience, are neither good nor bad. As hippy as it sounds, "they are what you make of them".

This quality, if you ask me, boils down to one property: Psychedelics are enhancers. If you feel beautiful and happy and lively, you feel REALLY beautiful, happy, and lively.

If you start to become frightened/anxious of something, or are in a frightening situation, you become REALLY frightened.

And this becomes further amplified by a second property of psychedelics:

Rather than the usual business of "Some external occurrence or sensation happened, and here is my one thought/reaction to it." IE "Wow, that statement was rude, what a jerk." Or "Man, that dark alleyway looks kind of scary, I think I'll not go that way."

Your subconscious and free-association become stronger respective of dose, to the point where they can become runaway.

No longer is the equation "1 external action = 1 internal processing response", but some small experience can set off a chain reaction of internal association tumbling down a bunch of different paths.

Dark alleyway -> Oh that's scary -> That's the sort of place monsters would be -> Monsters, oh those are terrifying -> Murder is terrifying -> I don't want to be murdered -> There's probably a monster in that dark alleyway -> Dark alleyway, that's so terrifying -> You know what's probably in there, a monster? -> A monster would murder me -> I don't want to die -> Die.. death...

It becomes a looping, inescapable schizophrenic sort of experience where you've also lost enough short-term memory to forget you've been going in loops like this for what feels like years.

And because things are so ENHANCED, the amount of screaming terror, dread, etc you can feel is beyond any thing you can comprehend. Time is slowed to a crawl, this can continue for eternity.

Now, if that all sounds awful -- just imagine this whole scenario, but filled with the most intense happiness and love you can imagine. That's what MOST experiences are like, generally.

---

What happened that night is I started getting anxious and fell into a dark place in my mind and got stuck there for an eternity instead of a happy place, to put it shortly.

I also won't pretend I probably didn't have a lot of subconscious trauma from a really messed up childhood and likely other mental issues/insecurities.
Yes, its working. I get emails when my comment gets a reply.

This license sort of sounds like a patent. The creators get to make some money for a little while and then it gives everyone access to the software.
You decide what's acceptable to you, yes. But in this case you deemed a $300 hardware device worth the money but you think this software product isn't even worth $20? Mind you, you're not just paying for the build here (which you can do yourself). You're paying for the development and porting work (which you can't easily do yourself and probably costs a lot more than $20).
Doesn't RHEL ship with NM by default? And test on its usage?
Invading is only needed if you want to control the place. A bombing/napalm campaign like the US did in the Korean and Vietnam wars, applied to the most important and populous regions of the country, would cripple the country for decades.

I didn't use amps because that is exactly what confuses people.

They use 30 amp pigtails for a 50 amp connector and figure it's just a little more.

Would it work better if I said 50 amp @ 240 is really 100 amp @ 120?

I have not extensively tested a 15-amp pigtail but as far as I know the circuit is identical. I have a 15->30 plus a 30->50.

(btw rooftop AC is 120v and all circuits/both legs work in my rv plugged into a pigtail)
Not "sophism" - 100% truth, unlike anything WaPo writes nowadays.
Except Icelandic people can read Old Norse, and that's all the hype you need. It's a bit more difficult for Faroese. It's even more difficult for Norwegians and Danes who will only be able to pick out a word or two. That's the continuum. Equally, a Norwegian can read Danish, but it takes from one beer to a wedding reception to get used to their strange laryngeal pronounciation, at which point the Norwegian probably is so drunk that he speaks perfect Danish. That's hardly drastic, although it might look like it is on paper. What's drastic is the day after. (Swedes don't count, and Norwegians are more than happy to explain it to them... in their own language.)
Skål!
I’ve tried to force myself to pick up vim a few times but after getting a bit older I realized that I don’t want to become one with my machine as a fighter pilot might be with their plane. I like the distance the mouse move and click provides me. I do more thinking and reading than typing anyways
Confidentiality isn't the only form of trust, many are simply annoyed with "features" such as wildcard catch-alls that direct you to ad/search pages instead of saying the domain doesn't resolve.
This is heavy. On the one hand I can hardly disagree with most of the points in the article. On the other, I'd like to have a more positive outlook in life than "corporatism is eating our souls".

I might not have a glimpse of solution (the article doesn't point any out, either) but I must agree that actively barring spirituality from seeping into workplaces is necessary.

We might have to act proactively as employees on this one - say no to cult-forming exercises in your job. I mean to the level of _let them know you will quit_ if management pushes this.

I'm worried most people out of tech will have no choice, though. The general job market does not look good.
I liked the example from Naomi Wu's twitter, that used it as an assembly line to print many identical pieces (or each slightly different) and drop them into a bin.

https://twitter.com/RealSexyCyborg/status/130143777389991936...

I also use my printer as the first step to a lost wax casting technique. A much longer print volume might make some steps easier, not having to connect multiple (or maybe just not as many in some cases) prints together before encasing in plaster. Sure I could just use a larger volume printer, but this is an interesting optimization to me that might fit in my shop.

It didn't occur to me that someone would apply this to moral facts, but why not.

In your example, the role of intuition becomes problematic if laws were based on it. Except that such intuition won't turn into a law unless a majority of people adopt it, which generally won't happen if it's not plausible enough. Although it could happen, and I agree with you that it could become dangereous, if reason and experts' opinions stop being highly valued by society.

> Should we make laws on the presumption that moral nihilism is true, or that it is false?

How should I interpret the "Should" in this question, as "In order to be consistent, should we make laws...", or as a moral obligation :) ?

The underlying assumptions in your question are 1) that there should be a single principle based on which we make laws, which is not necessarily true, that's why we end up with all kinds of inconsistencies, 2) that lawmakers care about philosophy when making laws, which doesn't hold for me.

I'm not well versed in philosphy, so I'm arguing here from my basic understanding of things. Laws are practical. What would be the practical consequences if laws were made on the presumption that moral nihilism is true?
I disagree that you know better. Research shows doing something daily and habitually is beneficial, but you shouldn't dictate that I need to do your content daily.

For example, in the past, I have often gone through coursera courses that were supposed to run for months within weeks, because I had a lot of time to dedicate to the courses.

I made going finishing courses a habitual activity, but I personally have designed it to suit my needs. In other words, I have tweaked the pace greatly.

You're consciously crippling your content with the idea that someone will benefit from slow pace. If a user wants to refresh some things, fill some knowledge gaps, or just take a look what the subject matter is about without the need for deep learning, you're adding friction to the process (and they'll likely not return the next day).

Now, don't get me wrong. If you get something out of it, e.g. Netflix releasing an episode a week for whatever gains they get, that's fine. But, if someone told me "read this book, you get 10 pages a day," I'd consider it a waste of my time.

Heh.

WRT schools, I only care because the controversy is a huge distraction.

Well, the older kid showing porn to my younger son was also a problem. Again, not something schools should ever have to consider.

This is just more license proliferation and a solution to a nonexistent problem. Releasing software under a license like the GPL doesn't somehow prevent you from making money from it. See Ardour - GPLv2, paid binaries.
Show HN: SMA and Per100k-normalized graphs of Covid-19 cases/deaths by country
Since daily COVID-19 figures in seem to vary wildly (owing to fewer cases counted at weekends, excessive cases counted after weekends, and ongoing corrections/adjustments), I built a tool to graph simple moving averages (e.g. 7-day-SMA, 30-day-SMA) of COVID-19 cases and deaths. This smooths things out and gives a clearer picture of general trends. The tool also allows you to normalize the same data per 100k people (to allow better immediate comparison between countries).

It uses the Johns Hopkins university data and updates automatically with the latest daily figures. I've got it running on an iPad in the corner of the room where it casts a warm, if somewhat miserable, glow on the room in the evenings.

Comments and feature suggestions welcome! Two features I already plan to add are:

- implementing swipe left/right to flip through countries
- data for a couple of notable countries is missing - I will of course add them (I need to aggregate the data for those first, as John Hopkins are publishing the figures broken down by region for those)
How about school districts don't buy non-repairable devices? Enterprise focused laptops are easy to service.
that sounds like a really cool story
Hmm. In the end, maybe transparency is a bad example, because people immediately jumped to approximating it instead. Wyman's review paper though is a good read regardless:

http://cwyman.org/papers/hpg16_oitContinuum.pdf

The GPU / accelerator BVH traversals are perhaps more applicable (e.g., https://www.embree.org/papers/2019-HPG-ShortStack.pdf) but they also have a different "I can restart my computation" property that say JSON parsing wouldn't have (though maybe if you're willing to do a lot of restarts once you parse the inner portions and push them onto a heap...).

Anyway, cool problem!

> humans can't tell if a review is fake from the text very well, but other things like an excessive number of 5* reviews is easy for a human to see

Shouldn't an excessive number of 5* reviews also be easy for a machine to see, especially when other indicators are considered?

For most Amazon detail pages I visit, I immediately sort by most recent. I have learned that the most relevant (which tend to correlate with earlier posting dates) are most likely to be fake, sometimes obviously so.
Here is a better analogy:

Not sure why the downvotes, I think this is almost a tautology. My perception is that Biden is just as "mainstream" as the previous opponent of Trump was - hence the slower decline of Trump's approval despite the president's performance.

That was my impression too. However, where a patent expires, I couldn't see when the source code had to be released by. Seems a bit problematic if that is the case. I also don't see a substantial difference to just releasing the source code at a later date under a open source license when the copyright holder chooses to.
It doesn't even make sense to talk about cases per existing case for imported cases, because by definition they're not caused by existing cases within the country. Like, maybe that could help tame down the clusters from those imported cases, but then you have to impose lockdown restrictions indefinitely and lose one of the big benefits of elimination over the "try and keep R just below 1.0" strategy - being able to lift those restrictions and avoid the ongoing economic and social damage they cause.

Also, I think that in reality this isn't actually as scale-free as the nice simplified models suggest, and having 100x the population would make it harder to stamp out spread within the country. Remember, the number of cases per existing case isn't some fundamental physical constant - it's an average over a bunch of different opportunities for transmission with wildly varying expected numbers of new cases per existing case. 100x the scale means 100x the opportunities for low-probability superspreading events that ruin your day.

VirtualBox supports USB 1-3, it has immutable disks built-in, it supports VMDK/VDI/HDD, it lets you drag-and-drop, it supports like a gazillion different controller formats, it allows host I/O caching, and like I already said it can be just plain faster... just a non-exhaustive list off the top of my head. Are you genuinely unaware of its features and strengths...?
You forgot to mention that Russia happens to have a lot of brainiacs. It's rare event to meet a dumb Russian in IT. I've never met one.

I have worked with and managed outsourced engineers from Russia, India, and South America. The Russians were consistently the best: effective combo of smart + hard working. The only negatives were a reluctance to disclose bad news before SHTF, which was quite annoying, but I've always put that down to residual USSR culture.

In other words, I question the early appearance of the term "piracy" in the list of reasons of why Russians excel at software engineering.
Have you ever had the opportunity to utter the words “can I buy you a drink?”? It’s usually preceded by developing rapport and by the time you know the answer to the question, it’s a rhetorical question at that point.
Right. Most people don’t care how it’s installed or know what apt or snap is. Those that do can find easy work-arounds like compiling from scratch.
Something people often forget to consider when they talk about all the benefits of being an editor power user: how often they get distracted or go down rabbit holes when tweaking editor config or using advanced features. I've worked with people who seem to spend half their day on this stuff.

So while it can certainly be impressive to watch someone who has mastered their editor, I always secretly kind of doubt that it's really much of a productivity win for this reason.

I think there are huge wins for getting proficient with your editor (refactoring commands, debugger, etc. as John Carmack mentions), but sharply diminishing returns beyond that.
Except we don’t tax non-profits and the rich are already smart enough to have trusts, foundations, a string of 506(x) variation entities, already at their disposal.

We need a tax system overhaul but I’m afraid no one has the political will to do it before stagflation creeps in from the current fed policies and bankrupts is all anyway.
They could outsource it. It’s wondrous that they haven’t solved this yet. I have to suspect they prefer it this way.
Even through Keycloak is more mature than ORY ecosystem I went with the latter as I have more experience with Go than Java. I'm only writing integration, dashboard. When those thing are ready I'm going to open source and offer a free option until I add billing, at that point you can either go on-premise or just continue with us.

Ory will probably offer a cloud service in the near future but I'm just scratching an itch for now.
You're the one who wants this, so it's you that will need to set up a Certificate Authority and then get it trusted everywhere for S/MIME. I genuinely wish you good luck with that.
Exactly. If you don’t care about stuff like that, why do you care about .deb vs snap?
I think the worst is plugging surge protectors into surge protectors. Or plugging a surge protectors into ups. (not all, but most)

We could get rid of capital gains tax and tax it as normal income. We could also get rid of like kind exchange. This money could be used to lower or eliminate income taxes for the poor. It is all about incentivizing how we want capital to be invested for the benefit of society. Today we've decided that shareholders are primary for public companies.

How would you have implemented it, while satisfying their constraints of extreme backward-compatibility?
Maybe the trickling in of mail-in ballots will soften the blow.
The reason to pick up vim is ubiquity, not efficiency. And you REALLY don't need to know much. Maybe half of what's in the vimtutor tutorial is enough. Personally, I'd also suggest at least learning how to do search/search & replace with regex which is easy too (and bonus, has high affinity with sed.)

That seems like the most any modern developer/*nix user should need to concern themselves with vim and wholly for the reason I mention above: it's the most likely text editor to be there on unix-like systems.
> What I find more important however is the effective window/buffer management.

Yes! I cannot imagine how my life looked before `C-x b` (switch buffers in helm).

However, I still have an actual terminal emulator open the entire time for serious stuff. Eshell is not compatible with a lot of programs, term/ansiterm are ok but not quite as good as a dedicated terminal.

I get around having to context switch by using virtual desktops (KDE). I have Shift-F1 bound to the desktop with only emacs, and Shift-F3 to my terminal. Works beautifully.

Rather than try to use a terminal in emacs I've found it more useful to use an solution designed for emacs, i.e git vs magit.

Just so you know: the "lacquer" used for kintsugi is actually urushi - the sap of a tree related to poison oak and poison ivy. Before you think about trying this, understand that your choice is to gown up completely and avoid all contact or just go with the rash and gain immunity over time.

That said, urushi in all its forms is one of the most amazing art forms - there are literally thousands of decorative techniques and uses.
Well I'm skeptical, but at least unlike 99% of "radically new type of open-source license[s]" I think this one is actually, y'know, an open source license and not shared source pretending otherwise. If I'm reading "External Deployment" correctly, it's sorta like AGPL but with a time delay, which is... Not terrible, really.
I picked up vim decades ago and I’m glad I did. I don’t feel “one with the machine” any more than I feel “one with the paper” when I use a nice pen. I feel like the machine is getting out of the way.
Yes, much better ways of representing and working with colours are known. Sadly, support for them is missing in most of the software we use, including Adobe Illustrator and Photoshop, the Affinity suite, Sketch, Figma and all major browsers. The best we get out of the box is usually HSB/HSL.

Of course, you can make the effort to construct a colour palette using a better model and then convert the colours. However, as soon as you start deviating from those carefully chosen colours — to build a gradient, or to apply filters or transparency, for example — you’re back to relying on the software to do the maths, and if its internal colour model is weak, the results will reflect that.
