But the point of this all is that rationality works within a frame; Bongard games are just an illustration that the real problem of meaning and choice and acting in the world is the not-rational one of choosing a framing.
I am currently obsessed with this game. There are so many meaningful decisions and a lot of trade offs between what is good now versus what is good endgame. I hope they keep adding content, but I feel like I could play it in it's current form for years even if they didn't touch it at all

You should visit the UK and get a native to drive you around some city centres. We have the full range of roundabouts from massive, traffic light controlled, multi-lain and chain-linked junctions, down to tiny roundabouts that are little more than a circular bump in the road.

It's rare that I stop at a junction that requires me to cross a traffic flow, lights or no lights, that I don't wish that a roundabout had been put there instead.

Collisions can at times bring a roundabout to a halt, but more often than not, people just use common sense and move around any obstacle, while maintaining as much lain discipline as they can.

Cyclists, so long as they behave as if they are cars, also rarely have issues at roundabouts. I'm quite accustomed, in my area, to following a cyclist around a roundabout, paying attention to their hand signals, and giving them plenty of space.

Basically, it comes down to training and practice. In the UK, if you can't handle a variety of roundabouts, you'll fail your driving test.
Show HN: Messages: A runtime-agnostic actor library inspired by actix
Serious question:

I fully understand the idea of historical algorithms being no true indicator of the future. With that said.......

If an algorithm consistently performs over 20+ years of data (through multiple black swan events, multiple major events), then why is it not safe to assume it likely will continue going forward? Wouldn't 20 years of "evidence" be a huge amount, such that future events likely wouldn't deviate much from that...?
They phoned me earlier this year and asked for $1500 USD. I asked them why we live in a country where people are starving, exposed, and sick in a country that has a bounty of food, housing, and healthcare. “Liberals are leaving the First Amendment behind,” says a person who probably has all three of those things. Feed people, and then ask for virtues from them.

> Though wouldn’t using arrays of structs kill the performance the same way as array of objects do (stack-allocated ones)?

Not really. Components are long-lived so they're not allocated on the stack. And contiguous arrays of structs/objects is the best case for cache locality, that's the entire performance case of ECS.

They're still at the bench-top stage with this, from the pictures. This is something that ought to work, since lithium is commercially extracted from denser brines.[1] Extraction from seawater is quite possible but not yet cost-effective. So cost is the big question. This is the usual problem when articles announcing "cheap and easy" come from the surface-chemistry crowd.

The authors write "a preliminary economic analysis shows that the process can be made profitable when coupled with the chlor-alkali industry." So they apparently want to run this off of the reject stream from a plant that extracts chlorine and sodium hydroxide from brine. Running this downstream of a chlor-alkali plant means somebody else already has a brine source and a way to get rid of all the rejected brine. This sort of thing is common. A lot of rare mineral extraction is done as part of a process that extracts a less-rare mineral.

Profitability is going to turn on all the usual problems with membrane systems - how long does the membrane last, how often does it have to be backwashed, what parts in the system corrode, and similar routine engineering problems. That's usually the hard part.

Actually, it makes an enormous difference. The supply of money that is created by banks can be increased and decreased through Fed operations. That means when inflation becomes a threat, the Fed can reduce the money supply, thereby reducing the money in circulation and reducing inflation risks.

Seriously, this is one of the Fed's primary tasks, to control inflation through monetary policy. It's sad how many people on HN fail to understand this.

In my eyes the trouble with the App Store is discovery is purely via curated lists and search. The problem with surfacing via each of these two methods is the user has to put trust into the system that what is being displayed is reputable and trustworthy. Apple unfortunately has shown that they prioritize monetary return over best-fit for content, which leads to scams like this. Let’s deep dive into the issues with the two formats they display info in.

Curated-list discovery (versus algorithmic discovery such as “top of the week”) tell the user that these apps have been hand selected by Apple for being quality apps. In general though it turns out that these lists are more often lists of apps that make Apple significant amounts of money, changing what Apple is incentivized to display. Take for example the only way they allow discovery of highly rated apps - the “Everyone’s Favorites (highly rated apps)” list: https://i.imgur.com/7D2hvwO.jpg. The top spot is held by Tinder, which currently has a 3.8/5 rating. This list very clearly isn’t a list of highly rated apps, only highly used / large money makers for Apple. We see clearly that Apple prioritizes monetary return over accurate results.

Search is another example of this. Most search algorithms are black boxes - inputs go in, results come out that we expect to be able to trust. Searching for “Samsung” should bring up apps from Samsung, but instead they return mostly free third party apps with IAP up sells rather than the official apps.

Overall the App Store is designed for monetary return, not safety or user trust. Until Apple decides that the long term image / trustworthiness of the App Store is more important than short term gain, I don’t see these issues changing.

It reminds me of the national debt/fiscal gap discussion. Everyone will agree you can't owe a million times GDP, but no one can describe the "limit". Every year and decade you have people crying out that it's unsustainable and will result in collapse, and you have people saying "nah, more". You have examples of countries imploding, and you have the USA with doubles down every X years.

Surely you can't parlay indefinitely, but there hasn't been an implosion yet... until there is... but then everyone who enjoyed the political and financial benefits of parlaying is long dead, their inheritors heavily insulated... or there isn't a financial implosion... or there's some other disaster rendering this disaster moot... or something else (free energy? Second Coming?) appears and fixes it, allowing the reckless to get away with it... if we ever agree on who the reckless were...

We could just follow Taleb's warnings (the precautionary principle, antifragility, black swan events), but we can't even agree on basic reality, and the people who are greatly benefiting off their version of reality will never budge, and the people who might suffer aren't yet born (probably).

I think there may be a chance for success in going FULL scrum, but really there are a couple of caveats.

* The appropriate sprint-length must be found, there is a lower-bound by how long you need for developing something with user-value (i.e. demoable), and upper bound the tolerance of your customer (or sales organisation) to wait until requested features will be implemented. Most scrum teams seem to use 2 week sprints which is typically too short unless you are developing simple products like CRUD applications potentially.
* If we take 1 sprint-length (1 SL) as a basic time unit, then you need to realise that a new, highest-priority feature will on average take 1.5 SLs to delivery if it really is Priority 1.
* teams must really be 90% self-reliant to do everything needed in the sprint. Once you have need to synchronise development across scrum-teams, you loose. basically now value delivery can easily take 2-3 SL OR needs to be carefully planned / aligned for the same sprint ahead of time so you get at a lower-boundary of 2-2.5 SL (> 1.5 SL) for work involving more than one team, easily exploding to 3-4 SLs.
deve
With these considerations, we quickly get into longer-ranges of planning, especially if you are in a multiple-team kind of situation, that you get easily into when you (a) don't have a dev team deploying to the cloud (b) are developing more-complex software systems with multiple components / services developed by several teams.

The elephant in the room of course is that all of this thais not discussed in your Scrum training, because they mostly outline a happy-path for this 8 person team

disclaimer: I prefer Kanban-style sprint-less work mode overall.

I was thinking along these lines too when the author went into machines solving the problems. One bit that jumped out was the quote from Hofstadter:

> They depend on a sense of simplicity which is not just limited to earthbound human beings.

Followed immediately by a problem whose solution depends on having a sense of 3-D objects in gravity!

Solving Bongard problems is surely a hard thing to get an AI to do, but I am wondering too about AI-authored instances. Or, say, problems authored by aliens, with a different evolutionary history, and different in-built biases for cognition. Would they necessarily be solvable by humans, or our Bongard problems solvable by them? Some aspects (number maybe?) are probably universal. But even a good-faith puzzle maker has to take some assumption of shared basis for perception.

This probably connects up to the author's final point that "what objects even are" is not absolute.
> But if you've got log paper, then all the lines are straight lines and there's nothing special about right now. It was a straight line yesterday and it'll be a straight line tomorrow.

I don't understand this point. If a point is interesting on an exponential curve, e.g. because it's within a human lifespan of human intelligence being exceeded (which I think is the context of the quote; I'm not looking to debate this point), how does changing the Y axis to a log scale make that any less interesting?

Those are almost certainly people making what I call "right hand turns from not the rightmost lanes", which is, IMO, the single most dangerous traffic violation a biker can encounter. It happens often, it's hard to avoid, and the consequences are bad¹.

My jurisdiction (and most I have encountered) require a right-turning vehicle to merge first into the bike lane, if there is a bike lane to the right. (And no further car lanes. Some intersections will shunt right turning vehicles across the bike lane, first, into a turning lane, and then turn at the intersection.)

My "closest call" was here: [1] I was going southbound through that intersection on a fresh green when a vehicle right turned from the left turning lane (i.e. he was also initially headed south bound). Absolutely crazy maneuver. I was forced into the right there (because otherwise, we were going to collide) and was just barely able to make it — I could feel the traction in my back tire was just barely holding onto the road the whole way through, since I was also braking like hell. Driver was just like "uh, oops?"

I'll usually watch the lane just left to me for drivers whose movement indicates some inclination of thinking about right turning (again, from the wrong lane). I don't know if people worry about blocking bikers or what. Like, if you're in my lane to make a right, and you're signalling that, I prefer that, because you're not going to pop into my lane & try to kill me. I'll wait behind you while you make the right. (Or merge around you on the left, if I can safely do so.) Or at the very least… if you're going to make an illegal right, please, signal.

¹way worse than things that sound worse: car driving the wrong way — which itself happens way more often than it really should — it's much "better": I can see it coming. Honestly, as a cyclist I feel like I'm the only person out there who took a course on how to drive a car.
Another issue is that once the algorithm becomes known, and used be many people, it will not work any more.
No, because of the survivorship bias.

People invent many algorithms all the time. You only hear about the ones which turned out exceptionally well.

Perhaps religious cult territory too. "The Algorithm" [1] is already being used to tell fortunes -- which if it just stays as a few people having fun with horoscopes I don't really care, it seems harmless. But I could also totally picture some cryptocoin charlatan getting revelations about The Spiritual Algorithm or something and starts selling AI for getting into heaven.

This is pretty cool. Just want to copy-paste a paragraph from your link that sums up how it's different from other tools:

>Cloud service providers like AWS and Azure leverage verification software such as the TLA+ model checker to achieve the same goal, but whereas those solutions typically verify a high level system design, Stateright is able to verify the underlying system implementation in addition to the design (along with providing other unique benefits explained in the "Comparison with TLA+" chapter). On the other end of the spectrum are tools such as Jepsen which can validate a final implementation by testing a random subset of the system's behavior, whereas Stateright can systematically enumerate all possible behaviors within a specified model of the system.
trading costs, liquidity, structural changes in the economy etc. del prado's machine learning in finance book gives some good insight into common backtesting pitfalls/thinking that are present here. the "safe" assumption if you find a systematic strategy that backtests well is that your actual, go-forward sharpe ratio will print 50% of what your backtests suggest.
There is still a spread.

I don't know, but it surely depends in part on whether you've published the algorithm. Once a strategy becomes well-known, its gains are likely to be arbitraged away.
Interesting

My ML knowledge is somewhat rusty... does overfitting occur more often on models with many input parameters (ie.. neural networks).

His algorithm seems very simple, without really using ML at all, it's more of just a procedural 1-2-3 step thing, with no actual learning.

Can you explain how overfitting works into his algorithm?
"Your primary day job requires attention whether or not you do any side projects. Side projects are additive on top of the work of your day job, but subtractive out of your pool of free time and energy."

For most people doing the side-hustle thing (and basically all of them doing it successfully), the calculus is "Put in the minimum amount of effort in my day job, get my R&R in the remaining time at work, and spend my mornings/nights/weekends working on the side hustle" vs. "Remain fully engaged mentally for the 8 hours I'm at work, relax when I come home, don't do the side hustle." That's why many employers hate side hustles.

I can't say which one is a better strategy, because it depends on the circumstances. Certainly the bulk of my lifetime income & assets comes from giving my all to my projects at Google, delivering successfully on them, and getting promoted a couple times. But before then I worked at a couple of startups and there was basically zero opportunity for a raise or promotion, because the company wasn't growing and there was no money to be had. And I got the Google job in part because of side projects (non-monetizable, but they showed I knew my CS and could work with a modern tech stack) done after work.

I dont really know why you are getting downvoted for a well reasoned counter-argument to the boundless optimisim.
the claim is that there is no natural process that will result in the double argenine sequence.

Adenine or adenosine can spontaneously [naturally] convert to a guanidine, or cytosine.

in addition recombination of two different RNA strands often occurs with RNA virus this is often evidenced by doubling of codons, often due to a "sticky end" break in the RNA strand.

thus something like AGGCGG may naturally and spontaneously transvert to CGGCGG

thanks for your interest gus

have a look here re: sticky ends

https://en.wikipedia.org/wiki/Sticky_and_blunt_ends#Overhang...

sticky ends are most common with DNA however this is also an occurence with RNA complexed to double strand in physiological conditions.

[ADNDM] it may be confusing to examine without this little bit; DNA is constructed of base pairs A-T and G-C and is double stranded as a central tendency

RNA is composed of a sequence of A, U [uracil], G, and C
but is often interpreted as a DNA sequence that would generate the RNA, espescially when speaking of [or working with] mRNA. RNA is not obligated to double strandedness however will form double strand complexes as part of its funtionality.
