4:30am works best for me. I go to bed between 9 and 9:30pm almost every night. Occasionally it'll be later due to some event or catching up with people after which I'll still get up at 4:30am but it makes me significantly more tired. It's quick to fix though, I just go to bed even earlier the following night, around 8:15-8:30 does it best.

I know these times won't work for a lot of people but if you have young kids it's awesome. They're asleep anyway and working at night tends to ruin sleep for me so I just go to bed! Then the next morning I can work in peace without it disrupting my body so much.

> Both sides do and say stupid shit in their own stupid ways.

The sad and hilarious thing is that both sides are often wrong in what they advocate, but often right in their criticism of the other side. It's probably easier to recognise bullshit in others (than in oneself and) than to get stuff right oneself.

Since the "Kafka trap" thing isn't something he advocates but something he criticizes his opponents for using, I'd start from the assumption that it's among the (increasingly rare) things ESR is right on.
I'm not sure what you mean? At the point of acquisition if you are given shares worth say £10k, it's the same as being given £10k cash, or £10k gift of some sort - you pay income tax based on the value of what you were given. It's different if you were given options - then the difference between your purchase price and sale price is taxed as capital gains with separate rules.

And no, it's a British company .
I also bought a microphone with a boom arm and shock mount (something like [1]). The sound quality seems good, and less typing noise is caught by the microphone than with a mic on the desk or monitor.

If anybody is wondering why those undocumented instructions exist:

https://www.pagetable.com/?p=39

...it's basically a tolerated side effect of the very simple table-based instruction decoding on the 6502. The main design goal of the 6502 was to create a very cheap yet practical CPU (compared to more complex and more expensive CPUs like the Z80), and one way to achieve this was to simplify the instruction decoding with a simple "switch board" even if this means that there's nonsensical "cross-talk" for some opcode bit patterns.

Here's also a very nice blog post by Ken Shirriff about the instruction decoding differences on ARM1, 6502 and Z80:

Have any of them been resolved yet?

Yeah the DES data would be fantastic resource when released. But wondering if it is worth compiling all open questions, if not already a resource. As in order to sift through data it's important have a complete picture of the full set of open questions we are dealing with.
Because a lot of development is paid by the hour/week, and managers' collective conscious took decades to perfect the art of pulling projects along - otherwise market forces (cost to land a customer vs revenue) won't make their businesses viable.

Also, because many projects are initiated by mistake or by sheer Dunning and Kruger effect (customers having more money than brains in general, and pouring it into the fields they have no idea about), that makes framing project in some coherent way, keeping it at least somewhat sensible looking to keep the money flowing, difficult, requiring a lot of back and forth and grudges, and makes keeping decent developers difficult because they are forced to do obvious bs, thus complicating completion.
Seawater contains uranium among other things:

"Seawater contains about 3.3 parts per billion of uranium by weight, approximately (3.3 µg/kg) or, 3.3 micrograms per liter of seawater.[6] The extraction of uranium from seawater has been considered as a means of obtaining the element.", from https://en.wikipedia.org/wiki/Uranium_in_the_environment#Nat...

(Mining uranium is as environmentally unfriendly as other mining operations, just do a web search for "uranium mining".)
Samarium cobalt are actually some of the best from this point of view, because they have a very high Curie temperature.

Most magnets made from cheaper materials with lower Curie temperatures, e.g. Nd-Fe-B or ferrites, lose their magnetization at higher rates at room temperature.

Losing a few percent of the magnetic strength for the whole magnet would be equivalent with massive data corruption on a HDD, because that is the percentage of magnetic domains whose magnetization has rotated, i.e. the percentage of corrupt bits. The magnetic materials used in HDDs have actually a much lower rate of spontaneous change of magnetization.

Nevertheless, when a single HDD contains around 10^14 bits, even a 10^-14 per year probability of a bit flipping at ambient temperature may cause one corrupt file per year of storage per HDD, which is close to the typical rates of corruption actually seen in reality.
But what about rust (not the language) ?

Quality should be removed from your list, butterfly keyboards.
I bet there wasn't one. The undocumented instructions are just unintended side effects of how the hardware works, not a ploy to give some programming teams an advantage via secret knowledge ;)
What is your recommendation for a cross platform program that can automatically create and store checksums for all the files in a HDD (or folder) and compare them with the files later and restore damaged files from another copy?
Ah, amazing. I had lost my NHS number, and had no idea how to retrieve it. Thanks for the link!
Do you remember this guy, Kanzius, who showed that you can burn saltwater when pumping it with radio waves? Yet, the citation trail seems dead because scientists assumed that he was a crank claiming he got more power out than he put in. No, he just demonstrated a really neat approach to electrodeless hydrolysis.

Author of FTXUI here. Thanks for this answer! This is exactly the right reasons.

Every terminal compatible with the main subset of the various VT specifications should be compatible with FTXUI. If someone can prove this wrong, I must fix this ;-)

I own a Linux machine so this is the "main" target. Support is quite strong.
However, I don't own a Windows machine and it's quite painful for me to test on it. Windows support has been added by contributors mostly. That's the reason I say it is still "experimental". The various Windows terminal requires some Windows specific calls to enable VT interpretation, as explained above.

FTXUI can be compiled toward WebAssembly and executed against xterm.js terminal. This proves you can use FTXUI against a compliant terminal and not really depends on OS calls.

There are some function depending on the systems:

- Windows diverges a bit (see above)

- Getting terminal dimensions.

- Getting terminal support for colors.

You can obtain a few things from desalination brines. Magnesium is the most plentiful, besides salt, of course. There's also some sulfur, bromine and boron that might be worth recovering. It's mostly theoretical, of course.

Blunt approaches like that are often ineffective.

A discussion that explains why it's a bad idea with the person arguing against the idea actually listening to the creator's defense is much better. Quite often people recoil at being told abrasively "that won't work" and end up taking the view that the person calling them out doesn't get it. Whereas a discussion where both sides have a push-and-shove to get to the conclusion sticks in the creator's mind and might even get them to stop pursuing it.
Damn flat.

If you write your documentation in Emacs org-mode, you could use include [1] to include files on other levels of your repository and then you could export it all to a markdown file for people, who do not know about org-mode and Emacs. This would make documentation anywhere in the repository discoverable / automatically included in your resulting documentation file.

That line of thinking assumes you can’t share maps, as such it’s of minimal practical value.

To abuse the analogy, a glovebox of old road atlas doesn’t beat Google maps. On the other hand mixing Google maps with your personal knowledge that a bridge is out is a useful meta map.
Yeah, I would be hard pressed to come up with something that I wouldn't be more than happy to accommodate if a candidate emailed ahead of time to let me know.
Ask HN: State of the art sport watch for privacy enthusiasts
Dear HN-community,

I've recently started looking into the modern world of cloud-connected heart-rate/GPS/sports-watches.

While the available products from Coros, Garmin, Huawei, Polar, etc., are tempting, I've been appalled by the lack of focus on privacy-related concerns for consumers.

It seems to be so common, nowadays, that I would have to share all my personal data (heart rate, sleep records, location data, activities, etc.) with the manufacturer, and other third parties - even though GDPR et al. should provide for a voluntary opt-in, while still making reports available for offline / local use.

However, what I would wish for, is a watch, which I can configure, and use - preferably on device, but if so needed, on a mobile device / PC, without having to share my data.

Does anyone of you know of a privacy focused solution, which allows me to use such a device and export the data for further use (this includes the ability to install (official) firmware updates without forced sync to the manufacturer's servers?
AFAIK, SSDs usually give one warning before dying, and that's suddenly becoming irreversibly read only. They might not always survive a reboot (which certainly would be the first thing I'd do if my OS suddenly reported a drive as RO) but you usually do have a time window to get your data off safely.

An SSD randomly giving the ghost is one of my greatest fears when it comes to desktop computers, because there's no way to get any data off them when they die. With spinning rust you can usually send the drive to an expensive data recovery company who will likely transplant the platters and send you a copy of what's on disk, but if a flash chip is slightly damaged because of a short or whatever, you won't have such luck.

Yes, I know, I should make more backups, but every time I thought I'd gotten everything safely backed up, I found a file or folder that I forgot to include.
It's weird sometimes but don't let this stop you from helping others, I appreciated your effort in any case.
Is Starlink also a "tube"?

I was (without any better argument than my intuition) arguing that the sentence “But it's more accurate to model these systems as semilattices.” sounds weak to me.
I was not making a point on the article, but only on this specific idea.

My feeling is that it's not really fruitful to describe "real life" phenomena in terms of abstract algebraic mathematical structures.
It's more of a gut feeling than anything else, but I think there are two points that one can make here:

* Generally, it's better to first observe a phenomenon, understand it, and try to find a good vocabulary for it, mathematical or otherwise, rather than take an out-of-the-box fancy sounding math concept and try to make it fit your phenomenon.

* It seems as soon as you try to describe a phenomenon with an algebraic object, you'll soon get stuck trying to make sense of your functions/axioms: what's the meet? what's the join, is there a bottom element, etc.
If you rather work with a more “geometric” notion (graphs, metric spaces,…) you don't have as many things to match, and you can focus on studying your objects.

To be clear, I don't have any strong point here, it's mostly gut feeling/rumblings.
That seems rather uncharitable. The primary use of the data almost certainly will be what it's claimed to be, helping various legitimate research groups to do their research and helping various legitimate organisations within or supporting the NHS to make sensible plans.

The real problem is the inherent risk that other uses will also be made of the data, legally or otherwise. Compliance with the rules for using this sort of data properly and securely has not historically been 100%, and this is Pandora's box. If anything ever seriously breaches, that's game over for the privacy of tens of millions of people, for life.

It's also being done very quickly, very quietly, potentially illegally, and on an opt-out basis, which should be reason enough for us to be extremely sceptical about the whole process even without the doctors here raising questions about the medical ethics involved from a professional perspective.
This is a great strategy to have but I would reformulate it as “make sure you know enough languages to solve system, scripting, frontend and backend problems efficiently”.

You don’t necessarily need a separate language for each domain.

The thing is that Tokyo has no city center. The actual center is the Emperor's palace, which is mostly empty and not accessible to the public.

Other than that, each ward has its own downtown, its own suburbs. It really feels like Tokyo is not a city at all but a place where different cities decided to stick together, and administratively, it is. Shinjuku would be closest to a capital but not everything centers around it, in fact, it is not even where the "Tokyo" station is.

Is this possible because of Brexit or is it just more unlawful data collection in the UK? If I (in Denmark) switch GP my new GP can't see my journals without me filling out a form to allow it and hospitals definitely can't access them no matter what as it is two independent systems.
That can still work, in a couple of ways.

You can have the programmer write bad documentation and file an issue for it to be improved. You can then enforce that releases don't go out until those issues have been resolved by the copywriter.

You can also implement new features in a branch with multiple authors. The branch doesn't get merged until the documentation is in good shape.

Pretty much, this comment spawned an entire thread of replies from, most likely, angry white people, complaining about the man who's name was in the title.

Not a single one had anything to say about Britanny King or what she had to say to Bret.

Got that? The video only briefly touches on Britanys interview with Jordan Peterson, and instead of hearing the black woman's ideas on BLM these psychopaths would rather complain about Jordan Peterson, they don't even realise the interview is barely about him.
I feel these two videos will help inform you, both interviews with evolutionary biologist Bret Weinstein with different doctors/researchers:

https://youtu.be/BNyAovuUxro

https://youtu.be/Tn_b4NRTB6k

The first video explains how/why the COVID-19 mRNA vaccine (new type of vaccine method) bypasses parts of the body's innate response that normally would create a spread /variation of spike proteins/charges to basically preemptively prevent and ready itself to more quickly attack minor variations that will occur - e.g. unnecessarily, inefficiently over committing to the COVID-19 variant while losing out strength/capacity to handle variants.

Second video goes into detail as to Ivermectin, where a very credible doctor practicing on the front lines of COVID, stating that Ivermectin is 100% effective of abolishing COVID-19 and all variants with the correct dosing/proper protocol. They also discuss how difficult it's been to get this practical knowledge out there and more. Ivermectin has had 4 billion+ doses already used globally and sounds like it is completely safe - used primarily to kill parasites by adequately interrupting their replication/folding ability (from my current understanding).

That is not what I took from the article at all.
Classes were never definitional for OO, so prototypes, as originated in Self and adopted in JS, are not a violation of it.

Function calls and messages are, fundamentally, isomorphic. Messages were never definitional.

The notion of "purity", everything is an object, was never definitional. That was a Smalltalk conceit. Alan Kay named the idea, but stole it. So he doesn't get to impose his religion.

What is definitional? Inheritance, encapsulation, methods. But when you abandon specious purity, OO becomes one organizational style among many. Where it is the right thing, it is. Where it isn't, something else is.

Sometimes mechanisms invented for OO are useful for other organizational purposes, without bringing along OO—which is fine. Implementation inheritance? Sure, why not? That's "bad OO", but OO isn't sacred, so not blasphemy. It has consequences, but they are sometimes—often, even—OK.

"Data-oriented"? "Entity-relationship"? "Functional"? "Pipelined"? Other organizational styles, also useful.

In places.

OO will not die. The others will not die. All organizational methods have their place. Games can have pockets of OO. Simulations can have pockets of OO. Nobody is keeping score.

Purity is a farce.
To open a LN channel you need an on-chain transaction. Same for closing a channel. Currently a Bitcoin transaction is around 7 USD.

That comment is picking at a fair critique, but some details seem to be wrong.

> rationalists hope that if they take one map, and keep updating it long enough, this map will asymptotically approach the territory

That is, as far as can be detected, what the human brain does. It isn't just the rationalists who have a view and keep updating it, hoping it will asymptotically approach the territory. It is exceedingly difficult to have a strategy that doesn't do that and still be a semi-functional member of society.

I'm struggling to see how someone could hold 'different' maps because they become one map in your head. Rationalists are perfectly comfortable with there being multiple possible scenarios leading to an outcome.

My guess is that this observation is going to the fact that rationalists are very, very uncomfortable (to the point of falling apart, sometimes) in accepting "because I say so" as sufficient evidence to update a view, change behaviour stop arguing and be a good sport about the whole thing. Which is very much a social faux-pas when dealing with high status people and often a mistake when dealing with inarticulate people who are nevertheless correct in their view.
Not sure how this differs from Christaller's central place theory of the 1930s except the nomenclature relies on a trendy modern borrow from bioengineering.
