I was surprised that I couldn't find any simple-looking solutions in this atlas. At first I was looking for Lagrange orbits, but maybe it makes sense to exclude them if zero-mass bodies aren't allowed. I think the equilateral triangle ought to be included though.
They’re not stable except at L4 and L5, and they all assume oke body to be massless. Arguably they are 2-body orbits for that reason. Not sure but suspect that this atlas contains non-massless bodies.
At double-digit kyu level, you should just play every day until you feel you are stuck.
After you get stuck, you should pick one thing at a time to focus on improving. But the one thing should probably be related to tesuji or life and death.
OGS (online-go.com) is the predominant server for players in the Western hemisphere, and provides a modern browser based UI. Fox has a larger player base, but that player base is almost entirely in Asian timezones. Fox requires downloading a not so modern client whose UI is lacking English translation. I get the feeling that Fox has a lot of bot players in the lower ranks.
It can take a few minutes to get a match on OGS. When that happens, I take the opportunity to warm up with a few tsumego drills on goproblems.com
Probably Fox would be the server with the most players but at DDK basically any would work and I think getting exposure to different playing styles would be worthwhile.
Traditionally, handicaps are usually given in the form of extra stones played on the board. This is a coarser resolution than points, with one extra stone in the opening having a strategic value of about 13 points. So he probably couldn't have won if his handicap were a full stone smaller, but he may have won if it were a few points smaller.
Leaving aside the question of whether the universe is discrete or continuous, a simulation would still have lower "resolution" than the real world, and some information can be lost with each time step. To compensate for this, it can be helpful to have simulation step t+1 depend on both the step t and step t-1 states, even if this dependency seems "unphysical."
Yeah this is a good shot at using existing verbiage, better than the candidates I came up with at least. Still not entirely self-descriptive, and has some overlap with usage in other parts of the codebase, like in data processing and user onboarding, but maybe that's a fine trade-off to make in order to use a normal word. I'd be equally fine with them being called "steps", but now I'm attached to my Keps :D
It’s a huge missed opportunity for the developing brain to learn about the world, its sights, its sounds, its interactions, its physics, its rules. Everything.
> However, even using extra hardware wasn't enough in this case. So they pre-calculated lookup tables for sine, cosine, tangent etc. for every angle at the necessary precision.
Is this really the order of events? I imagine the pre-calculated route is what you'd try first, and only go for extra hardware if that failed somehow.
What's so difficult about optical links from deep space compared to low earth orbit, where 200 gigabit throughput has been achieved? Is it just the attenuation?
I would have imagined that we could upgrade the communication equipment on a space probe much more easily than we could add fuel for a return trip.

Yup; 300km vs 600000000km. Less than a trillionth of the power comes through for the same emitted power and apertures.
So, you end up having to make apertures much larger and point much, much more precisely. You can also increase laser power some, but that's a small part of your solution.
(Or, of course, you can reduce speeds to have more energy per bit).
I don't think anyone is serious about shipping back physical data from deep space, but the station wagons full of tape thought experiment is always fun.
I am semi-serious. But it's more about a periodic backup of an on site science station.
An on site (orbital) station could run all the models and algorithms and analysis you want on the gobs of imagery and spectral maps / cubes you can gather in real time.
Analysis is an excellent compression algorithm. But, you'd want the raw data eventually, and that means either trickling back 0.1%, or waiting a few years for the full set.
What’s your sense about SETI or the Fermi paradox, if a signal becomes so vastly diluted just within our solar system?
I’m sure the SETI people have thought about this and made various calculations, but with the inverse square law and the vastness of space, maybe “needle in a haystack” is optimistic.
Is it the wrong model to think that anything but maybe a galaxy scale civilization is just going to have it’s signals more or less totally dissolved into seemingly random cosmic fluctuations, relative to our sensors/receivers at least?
Maybe. Recovering data on interstellar distances is hard.
Integrating a long time to see if there's a signal there above background levels is maybe not so hard (especially if it was intended for detection in this scenario).
The big issue for data recovery is energy per symbol. If you can integrate for hours, that can still be a lot of "special photons" (whether they're on a weird radio frequency or light wavelength).
