1) Figure out how to reliably and predictably get people into your app. Know where to advertise, how much it costs and how to optimise your ads and storefront. Don’t have a “build it and they will come” attitude. Solving this problem at scale will be roughly half your total effort.

2) Once users get into your app, figure out how to keep them around. Identify how often you want users to use your app (once a day? Weekly? Etc) and design the entire app experience around promoting that form of behaviour.

3) Really understand what is unique about your app (compared to all others) and emphasise it. Ensure new users understand it and experience it. Most users drop out minutes after first launching your app.

I think it's for humans. Often humans looking through SQL code are doing so for performance reasons, and a recursive query is fundamentally different from a non-recursive query. It's something you might want to know while skimming, before diving deep.
Eyeball planets are quite common, easier to detect, and potentially life bearing.

Tidally locked planets have a greater range of distances they can be from the central star while having a habitable zone. Non-locked planets need to be at just the right distance.

As to which kind of planet we'll find life on, depends on whether tidally locked planets with habitable zones are more frequent than non-tidally locked planets in a habitable orbit. I don't know that we know the numbers here.
You could write the same solution in prolog. The difference between yours and the original solution is the latter follows the original program specification and is easier to compare to it. That is, it defines what the problem is, not how to solve it.

I don't think it made that claim (The HN title appears somewhat incorrect) - just that we are primarily detecting what are likely to be eyeball planets, so if life is out there on any of the planets we are detecting, then it'll most likely be an eyeball planet.

It's a bit circular and not really saying anything useful, but at least it's not claiming what the HN title (nor your criticism) is saying
> Non-locked planets need to be at just the right distance.

We are learning that there are liquid oceans all over our solar system so I'd argue that the classic concept of a habitable zone is outdated because it doesn't take them into account.

The issue is that no-one has a cast-iron definition of what exactly amounts to a measurement, outside of something entangling with the system being measured.

You can "disturb" a two-slit system, for example by creating a third slit which will change the "interference pattern" or pattern of probability of detection on the screen, without this being a measurement, though, so the concepts of "disturb" and "measure" are distinct.

They seem to like attacking the right; but it is the left which already screams about the world being overpopulated, are intolerant of religion or morals, advocates eliminating poor people through birth control, getting rid of "undesirables", uses violence to get their way, etc. and everyone seems to forget the Nazis were actually the "National Socialists", left-wing, not right-wing, but officially denied being either. I'm not saying the right is much better, but painting the left as being panda-bear loving hug-givers and the right as monsters is a very biased attitude.

EDIT: main point being, I think it's a very biased article with little evidence of their claims. Sure, I think there are some bad things going on, and that we should take care of those, and that society should be less complacent, but forecasting doom and a certain group of people as being ruthless is a bit far out.
The background for the article is 'tilt erosion time' and the large number of tidally locked planets in the habitable zones of numerous low-mass stars. Many new discovered planets are tidally locked: Kepler-438b, Kepler-442b, K2-3d, K2-155d. It was previously assumed that tidally locked planets would not be habitable. New climate modeling seems to change this view.

My order of discovery was more like this:

1) Recursive CTEs: that's nifty; I'll remember that for when I need it.

2) Here's a problem that involves chasing a linked list of rows, I know, I'll use a recursive CTE.

3) Oh dear, that doesn't perform well at all, I'm much better off denormalizing my lists into a separate column and using LIKE expressions, or something similar instead.

I think so. Four billion years doesn't seem like enough time to evolve the the sophisticated encoding mechanism of DNA and the level of complexity in individual organisms and the interdependencies they have on each other.

I really wish I could find a sort of statistical breakdown of the odds of this all working purely by chance (I'm definitely a fan of evolution and i'm not necessarily invoking woo or God here, just thinking that there are mechanisms at play we don't understand, and a head start would explain a lot for me)

This is how my hopelessly naive mind thinks about the problem:

Let's round up to say there is 10^15kg of biomass on the planet[1], and there are 10^12 cells per kg[2]. Let's assume that those cells have reproduced every hour for the last 4 billion years (or 35x10^12 hours). That's ~35x10^39 opportunities to pass evolved genetic material to the next generation of cell.

One of the organisms with the simplest known genome is mycoplasma genitalium[3], with ~588 genes expressed over 580,070 base pairs. Each base pair has four possible configurations (A,C,G or T).

I don't know much of anything, and I definitely don't know the rules around how the base pairs come together. I'm going to naively assume that these base pairs can come together any way they like, and that mutations in DNA express themselves as changes in these sequences. This leaves the DNA of mycoplasma gentalium with 4^580070 or 8.7*10^349236 possible configurations of their DNA.

Obviously only a small portion of those are viable. But how do you get from nothing to something of the complexity required to reproduce, and then how do you get from something of that level of simplicity to the genetic diversity that we have on the planet. How many generations from the first living organism are there to current people. Let's say it's a trillion generations. How does random mutation bring you from say a half a million base pairs at the beginning to 3 billion finely tuned base pairs[3] at the end? It just doesn't seem like enough time to me.

The FAA is a common source of criticism and complaint among the aviation community. It's the driving force behind the continually rising costs in general aviation. Owning a small single engine plane with a hull value of $40-50k requires a financial commitment tantamount to purchasing a second home.

But, it's good to step back and recognize every now and then that every Federal Aviation Regulation (FAR, 14 CFR) is written in blood. The FAA can be a pain to deal with sometimes but every pilot I know is very, very glad that they do what they do.
The rationale is because carbon chemistry is the richest chemistry out there. Other elements are not nearly as flexible to sustain complex molecules while maintaining the possibility of reversability in chemical reactions. Thats actually a very sound argument.

In my view, there seems to be some confusion in the paper between 'discrete' and 'digital': "Furthermore, in the present work, the terms continuous and analog are treated as equivalent in an engineering sense, as are the terms discrete and digital.' [my emphasis]. A similar conflation is seen in several of the quotes from other work in the introduction of the paper.

I think there is a distinction between 'discrete', where the signal is encoded as a non-continuous physical property, and 'digital', which adds the concept of place value to discreteness. This distinction is relevant, for example, where the authors contrast the ability of digital recordings to resist the degradation that analog recordings suffer from. That resistance, however, depends quite substantially on error-correcting codes, for which place-value matters.

I did a quick googling, the earth's orbital speed is 29.78 km/second, so you'd need to cancel that out first, then speed up again to match the speed of the asteroid. For comparison, you need 9.4 km/s of delta-V to bring something in low earth object (7.8 km/s for orbit, plus 1.3-1.8 km/s for atmospheric and gravity drag). To put something in counter-rotating low earth orbit, you probably also need to add the rotation speed of the earth (at the location of launch), but, I don't know the figures there (not a three second googling away).

So uh, yes. Needs a rocket with at least four times as much delta-V as what we currently use to put something in orbit. I'm reading the New Horizons project, which up until now was the fastest thing to leave Earth, was shooting away from us at 16.26 km/s - all from chemical thrust. The Voyager 1 is still going a bit faster thanks to gravity assists.

We are detecting planets that are close to their host stars because they are relatively easy to detect using current methods.

If a planet is closer to its star, it's more likely to be tidally locked. It can however also be in a spin-orbit resonance higher than 1:1.
> One common use case I've found for recursive CTEs is generating tables of dates.

Probably a bunch. I'm not a rocket scientist, but Google tells me Jupiter's orbital velocity is about 13,000 m/s, with Earth's velocity being about 30,000 m/s.

If my KSP-taught understanding of orbital mechanics is correct, you'd first have escape earth's gravity(~13,000m/s), then reverse your orbital velocity(about 60,000m/s, also matching the orbital plane of the asteroid in the process), and then do a standard hohmann transfer to the asteroid orbit(looks like about another 5,000m/s) just to get to the asteroid, but then you have to cancel the closing speed. I don't know enough to know how to calculate the approach velocity but looks like it might be a bunch.

I find that it completely unlikely that 'eyeball' planets would have a life-supporting zone.

Over geological time period, the zone is likely to suffer unpredictable and novel variability which is not conducive to developing life.

I do think the biggest pro for CTEs is the increased readability, and using recursion inhibits the readability a bit (still better than the alternative). But I'm curious how complicated the SQL you're using is that it takes half an hour to understand what it's doing.
Actually the VCs don’t make out so well either; VC as an asset class generally underperforms the public markets. A few whales (Kleiner, Sequoia, et al) run the market, and they’re market-makers who prop up valuations and bring in other folks.

VC is a gladiatorial ring where rich people do economic battle with each other. But it’s largely zero sum with some small, highly localized gains.

I created my company at 18yo while being a programmer/geek. For me the utmost important thing is to focus on communicating with people (employees and customers). Being a CEO is 99% human management.

For someone like me, with poor social skills and mostly "logical brain", it was really hard. I say "was", but after 16 years, it still is.

Also, while it might seem "good", don't try to manage your company like family. You will have to take difficult decision, you will hurt people. Just be straight and honest with people.

Treat human problem first. Speak one on one with every human around you on a regular basis. Be discrete and protect everyone's privacy.

Finally, find someone you can exhaust to, you will rage, you will cry, you will feel lonely, and if you don't have support, you will perish. For me it was/is my wife but I find myself lucky.
The most interesting thing that came to my mind reading this was how different life would be without any distinction between night and day.

Yes, and an entire wing going missing is not the same as 10% of your wingspan (less in terms of area) coming unhinged.

You made up the "all the time" part and then put it in quotes as if it were a direct quote. Please don't do that.

More than 60 passengers had to be flown back to London City Airport after part of the plane's wing fell off shortly after it took off"
