Cycling to work (weather permitting) (I used to take the Tube).

Home workouts, using mostly body-weight exercises (along with rings and a pull-up bar). I no longer go to the gym, so there are less "transaction costs" to exercise; we'll see how this one will turn out.

Taking less organized notes, mostly in one "Notes" email draft in my Gmail account. Reduces the mental friction/resistance to taking notes, because I don't feel the need to keep them tidy.

Some time ago, I started using smaller plates, to reduce the perceived, and therefore hopefully also actual, portion sizes.

I'd be surprised if it's not that easy in most jurisdictions. Failing/empty malls are a huge waste of space and an eyesore. I can't imagine a city council not jumping at the opportunity to turn one around even if it meant leasing some of it as office space.
Perhaps he’d say that such a triangle doesn’t exist physically.

I am certain that this is the case given that he's referring to the maximum information density density of space as one of the reasons why exact numbers make no physical sense. See https://en.wikipedia.org/wiki/Bekenstein_bound if you don't know about that limit.

More directly, the inability to represent exact lengths falls out of the Heisenberg Uncertainty principle. As an abstract mathematical concept, numbers could be anything. As a physically relevant concept, there are limits to how much precision can matter.

The difference in terms of fusion and fission is not that large. In fact I would argue that any likely fussion plant would have the exact same capx problem that fission now has.

If we can't get fission to work, fusion will not help us.

Compared to carbon based fuel fission is 10^-12 more dense, while fusion is 10^-15. While that is a large change I don't think it matters when competing with wind.

> even with the new advanced plants

I disagree. Once we mass produce nuclear plants the price would be radically reduced, just like in any other mass produced object.

The problem at the moment is nuclear is almost to dense and long running. Its hard getting the scale you need to do that. Specially if every single place you want to put a reactor you get sued 200x by Greenpeace and everybody else.

Compare a nuclear reactor to a rocket engine. SpaceX produces rocket engines for incredibly cheap amounts and he produces 100s a year. A nuclear reactor does not need all that different materials or attention to detail.

The problem with nuclear is the development cost and the regulatory hurdle. If you clear that then you have to find costumers enough to have mass production.

That is why it has not happened and unlikely to on a large scale.

However if nuclear reactors were produced like solar panels and you had global markets, nuclear would trounce solar in terms of price.
Well, my reasoning goes like this:

1. Industrial revolution made obsolete physical work. The physical work that is done today (for instance, blue collar workers, waiters) is about mental capacities, not physical.

2. The brain is a physical object that process information (no magic).

3. At some point we will able to create machine that process information better than the human brain, making humans obsoletes.

If we accept that premises, the only question left is "when?".

I agree with that.
Short Gitlab tutorial for curious people
The author's writing has a lot of background behind it that is true and yet the author's argument that they should be called "random numbers" is poor, at best. It is not typically helpful to think of real numbers that way - at the very least you're "missing" a tiny but hugely important subset that aren't random in any sense. But more importantly, it doesn't match up with any of the usual definitions of real numbers since those involve no such restrictions of randomness of digit expansions (and generally avoid digit expansions entirely). We might as well argue that the real numbers aught to be called the non-zero numbers since almost every one of them is non-zero.

I don't think the author seems particularly aware of the existence of such arguments in the past (I assume he comes from a physics background and is new to this - though so am I). Glancing through the works cited I don't see references to past treatments of this idea like Chaitin's. If the author is not a crank, he is doing a poor job of convincing us of it.

Keeping a diary. I started somewhere around the beginning of 2000, but unfortunately on paper which I have lost. In 2005 I switched to digital. I lost some more notes due to using a proprietary format and app crashes but have since then written my notes in plain text. I have around 3500 (standard book) pages of personal notes.

I started keeping a diary because I wanted to write fiction but couldn't keep at it, so I just put my streams of thoughts on paper. Later I got used to writing daily, and it has become my primary way to relax and clear my head.

Reading what I was doing and thinking ten years ago has been very valuable to me. It's a treasure trove of memories. But it is way more than a nostalgic pleasure. It has helped me to understand my thought processes. And distance myself from it.

It made me realise the meaning "you are not your thoughts" on a deeper level that is hard to explain here. I'm very happy I started this so many years ago and kept at it.

There are a bunch of different products under the JB Weld brand that are two part clay like material. They are designed for things like patching wood, patching metal, etc. The two parts are different colors, so you take the two parts, squish them together, and knead them a bit until they have a uniform color and then you can mold them into whatever shape you need. I've used the wood one quite a bit for repairing small rotted sections of wood and it works well. Not sure what the shelf life is, but in it's two part state I've had containers around for over a year and they seem like new.
Apparently it is the week I really live up to my current HN username.

I'm sorry I do not want a subscription for everything. There are a few things that make a lot of sense on a subscription. Phone service, Netflix, cloud services etc. Car leasing can make sense.

There are an awful lot of things that are being forced into a subscription model. Editors, routers, throwaway printers with their delightfully expensive DRM'd inks. Purely as a means to squeeze a little more cash out of the punter.

"It seems inevitable that subscription services will come to more routers. We rarely buy new ones, and subscriptions give these companies a way to keep making money"

It does? Why? After 30 years of free, mostly junk, modems and routers from the ISP that rarely got replaced? Routers get replaced when the magic smoke escapes. Unless you're an outlier, like me, who reads HN the only interest you had in the router was connecting the phone and laptop when you unboxed it.

No, can't make sense of this.

No, I don't want an extended warranty with my £29 toaster either.
Well, it would be PPP adjusted income minus nominal housing costs then. But since housing costs factor into everything you purchase, that metric would probably only give you a sense what was being spent locally vs. spent everywhere else and/or saved.

This has been a known bug since November 2016, which was supposed to be fixed for version 3.3.3.

All these comments dismissing this model are just reacting to the flippant tone in the article. ~70% of service calls to ISPs are for issues that are within the home, be it interference, or a misconfigured or even unplugged router. Managed WiFi, where a rented router is remotely administered, is a very good way to deal with this stuff. It greatly reduces the number of truck rolls that an ISP has to do. Sure, maybe ATTs service sucks, but everything they do sucks. I am a little puzzled by the choice to sell this straight to consumer, since most managed WiFi manufacturers sell their routers to the ISP to be leased to the consumer (or supplied free).

"Essential" is not some arbitrary assumption, but a term of art specific to Debian Policy, and a flag applied to specific packages:

Essential is defined as the minimal set of functionality that must be available and usable on the system at all times, even when packages are in the “Unpacked” state. Packages are tagged essential for a system using the Essential control field. The format of the Essential control field is described in Essential.

https://www.debian.org/doc/debian-policy/#essential-packages

Diversions are addressed in 3.9: https://www.debian.org/doc/debian-policy/#maintainer-scripts

Debian Policy, generally, tells package maintainers, not users, what they may or may not do. Several classes of conflict are listed in the document; Microsoft's scrips violate multiple requirements.

The goal and result of this ststem, arrived at over 21 years collaborative development (Policy was first published in August 1996) is a system which provides well over 60,000 packages and behaves surprisingly robustly from the user-administrator's perspective. Which is to say, there are few surprises.

Microsoft have violated multiple Policy requirements. This is considered a release-critical bug in distro packages for very good reasons.

Do the other news sources you use explain the disadvantages of net neutrality or alternatives that could provide better results? If they present it in only positive light, then they're one-sided too, you just don't notice because it' the side you're already on. Even calling government regulation of the internet "neutrality" is biased.
Possible moats:

1. the cost of having and maintaining a fleet of scooters
2. the network of flexible staff charging scooters
3. proprietary battery packs
4. the network of flexible staff moving the scooters to better locations
5. exclusive access to a scooter with a performance profile that the rest of the market cannot match (think tesla).
x. contractual moat

1) will not stop startups with access to funding from entering the market. Providing service will require a fleet of these lite EVs and as the economics becomes obvious, the companies will merge (so they share overhead costs) until there are only one or two fleets.

2) Is very short term, because eventually the companies will figure out that they can get their users to charge the scooters themselves - by literally bringing their own battery pack (it's pretty portable - see https://electricscooterparts.com/batteries.html) to the scooter and plugging their battery in. The scooters will validate the powersource to ensure it's safe and that will be the end of the "paying random people to charge scooters" business.

3) They can't even charge for proprietary battery packs and use that sunk cost as a moat, because with VC money, competitors will just give away their own proprietary battery packs. Maybe the switching cost will be the time it takes to receive your free battery pack in the mail, but you'd just order a free one from each competitor in your area, so this is an insignificant moat.

4) Is also relatively short term: They will also eventually tell users where they are allowed to leave the scooters, and charge people who don't comply. They may frame it as a discount, but.... In the end the hard work will be outsourced to customers, which means there will really not be lock in. Any leftover work will eventually be done by professionals, or maybe by a smaller network of people moving scooters, if they are cheaper.

5) This is the best moat, but it's similar to the moat iphone used to have. They will need patents and to basically be on the forefront of the industry, forever. Boosted Boards is likely to wind up occupying this position, though they are likely to not directly operate their scooter rental product, but instead sell the scooters in an exclusive agreement to a particular company that turns around and wins the market with lower costs and higher reliability. Boosted would use their monopoly position to extract as much profit from that partner as is possible while allowing the partner to still be cheaper than getting and maintaining other scooters. Eventually their partner will try to clone their product and get it cheaper elsewhere, unless Boosted's patent game is very strong.

x) I think there's another possible moat. A particular service provider may be able to force users to agree that they only use their own boards in order to have access to lower marginal cost. Users may get a discount for not having the competitor's app on their phone. Alternatively, a provider might allow users to buy like $500 credit up front for a significant discount to achieve similar impact.
> 0.5 is a real number. Its series of bits is not random at all

Would you say that an (arbitrarily long) sequence of coin tosses that all come up heads "is not random at all"? I'd say it's vanishingly unlikely to occur (if the coin is actually 50/50), but just as unlikely as any other particular sequence of the same length. It's like if a lottery gave out [1, 2, 3, 4, 5, 6]: it's a remarkable pattern, but no more or less likely than any other particular result. The same goes for the never-ending decimals of 0.5 and sqrt(2), and it's misleading to draw general conclusions from such specifically-chosen examples.
They never claimed to provide support. Only something vague called active management. What could you possibly imagine that would actually be that would actually help anyone in any actual real-life case?

For this stage of drug discovery (finding potential hits off of ligand databases, finding potential targets, and refining ligands in silico without running real high-throughput lab work) machine learning may work better at lesser cost. It's the direction (some) research is going right now.

Of course the real cost of drug development is running clinical trials, and losing something like 90% of ligands because they don't make it into the bloodstream, can't be synthesized at scale, or wind up having no efficacy in vivo for no reason anyone can fathom.

(Even making "copycat drugs" where you pick a known target, known ligand class, and try to minimally alter the synthesis process to get a newly-patentable product can sometimes have odd surprises, including the kind of odd surprise where being more specific to the identified target leads to diminished efficacy.)

This goes to show that fundamental research in biochemistry is still needed and we are nowhere near having "cracked the code", genomics notwithstanding.
The network effect would be fairly strong within a regions/city. Though there's nothing natural about it, there are pragmatic barriers to this that would give a deployed service provider a quasi monopoly in a city. You need to have enough of them out there, you can offer discounts to flush out competitors, brand recognition. Also things like sign ups: if someone is signed up with an incumbent, it would be easier for them to just take that Scooter as opposed to an opponent.

It's a crazy play, but if scooters 'become a thing' then it's a good deal.
I like your definition of "look".

I was going with where a dart* would land (100% of the time it will "really" hit a point that can't be expressed using computable numbers), but you're using it to mean anything we can compute or express. That is, if we're looking somewhere, it has to be somewhere we can say that we're looking, and therefore expressible. If we take your meaning, then yeah, that's what I mean as well :)

* (Yes, the dart is an abstract one. No comments about the Planck length, please)

Yes, the very next sentence of the abstract says:

> Most physicists straightforwardly supplement classical theory with real numbers to which they attribute physical existence, while most physicists reject Bohmian mechanics as supplemented quantum theory, arguing that Bohmian positions have no physical reality.

Bohmian mechanics is a hidden variable theory.
I'm curious about something, figured I'd ask since there are some math people on this thread (I was an undergrad math major but wouldn't include myself in that group, for the purposes of this question).

The abstract contains the statement: "moreover, a better terminology for the so-called real numbers is "random numbers", as their series of bits are truly random."

Has this been proved? I suppose another way to ask it is, if the sequence never repeats, does that mean it is random?

For instance, if the sequence was

.1121231234123451234561234567... isn't random, but does it resolve to a rational (can this sequence bet represented as the ratio of two integers)? It would be a never repeating sequence that has an upper and lower bound that approaches zero as the sequence continues, right?

If my example turns out to be a rational, is it possible to construct a non-random sequence that would still never resolve to a rational?

I might try to look this up and read about it a little, it's been a while.
Why pave the road with solar panels. I like the idea of covered roads. Put a solar panel roof over a road and it will last a LOT longer. Especially in bad weather areas. But it still makes too much sense to put the panels somewhere else. Easier to maintain and way cheaper to install.

Bikes are in a no-mans land because of speed differences -- they're too slow to go on the road, and too fast to safely mix with pedestrians on sidewalks.

I personally prefer dockless bikes over scooters, but I will admit that scooters are safer because of their lower top speed. This makes it reasonable to mix scooters with pedestrian traffic provided that the sidewalk is wide enough.

The key to making bike/scooter-sharing work is to make the infrastructure cheap, incremental, and easy. Google ran into the same problems with GBikes blocking ADA ramps and front doors that cities are seeing with scooters. One big thing that helped was converting a few parking spaces into bike parking (literally just green paint and a few signs), and putting friendly "don't block ADA parking or ramps" signs up.

If you want to prevent "deaths from drivers", the highest impact thing would be to work on self-driving cars (join the great engineers at Waymo, Cruise, or even Uber).
