I discovered a game in the Go family.

It's played on a grid of overlapping circles, without counting the origin as an intersection.

Every intersection has exactly four liberties, so it adds an optional move of a stone after each placement. Liberties are counted after both the placement and the move, so a player can't occupy a point with no liberties and then slide to capture.

Anecdotally, it's enjoyable.

Thing is, I came up with it in the year 2000, and it doesn't appear to have existed before that. This experience has left me skeptical that it's obvious that an alien race came up with Go. They might have.
Free-for-all is the best solution. This way everyone is disappointed evenly and randomly.
For a long time, the answer was probably performance. Lots of people were trained to use Lisp in their computer science courses, and lots of people admired it. But it was never anywhere near as fast as C, and in the seventies and eighties squeezing every darn bit of speed out of your hardware was what counted.

The language had another chance in the nineties, when it became important to save not just execution time, but the programmer's time also. This is when interpreted languages like Perl and Python started showing up in a big way. I'm less confident why Lisp lost out that time, but its weird syntax is probably at least part of the reason.

This is awesome!

Any idea where Chess would stack up? I'm assuming it'd be greater than Checkers in that list, but how much greater? And would Nim be simpler than Gomoku (Connect-N)?
>I was traveling with an older Android phone (Android 4.4.4). I couldn't install the latest version of the app. I tried installing an older version, but it simply said I needed to upgrade. So, I couldn't play any music from the phone. I checked online and a number of people were complaining they used their older phones and tablets in the house as simply a Sonos remote, and they now had to upgrade all of those devices after support was dropped.

Reminds me of a similar frustration with OS X. In December 2017 I was trying to use bluetooth headphones with a MacBook that was still on Mavericks or Yosemite (10.9 or 10.10, latest version at the time 10.13), so yeah, a little behind the times.

But when I tried to connect, it said I had to upgrade the OS to use bluetooth with those headphones. What? I'd connected to my phone with it with no problems, and the protocols for the connection are like 10 years old, and almost certainly existed in that version of the OS.
> Lisp hackers create works of art that no one else can figure out after they leave.

It's possible, but it's not necessarily so. There are many Lisp code bases which are 20, 30, 40 or even 50 years old and still maintained, passing on the work to new generations of programmers.

Maxima has bits from the end 60s. Cyc is under continuous development from the early 80s onwards. SBCL is based on Spice Lisp code developed at CMU from 1981. The commercial implementations Allegro CL and LispWorks with their IDEs and libraries are under development since mid/end 80s. Axiom/Fricas computer algebra systems started the code base in the 70s at IBM as Scratchpad 2. The first MIT LOOP macro implementation was written in the 70s and then modified as Lisp dialects changed. The G2 process control system by Gensym started mid/end 80s and is still being sold. The SPIKE telescope scheduling system from NASA is still in use for various large earth and space telescopes - originally development started in the end 80s.

I've seen code bases which I could not understand from looking at them - rare, though. The biggest problems were code bases which were tied to a particular implementation and OS. For example the Sk8 multimedia development environment written by Apple is non-portable, since the Lisp code uses Mac native graphics/multimedia libraries everywhere directly from Lisp and is not abstracted in a layer.
Although responsibility is important, firearms aren't an "awesome" responsibility. Millions of kids use firearms safely; some quite young. It's in the same ballpark as other ordinary responsibilities like driving, maintaining a swimming pool, using power tools, etc. As far as recreational activities, those involving guns aren't particularly dangerous (statistically).

There are something like 400M civilian-owned guns in the U.S. If it were an awesome responsibility, then we'd all be dead by now. But murder rates are low and either steady or declining.

It's easy to say that other people seem irresponsible, but we need to look at the data. Firearm accidents resulting in death are very rare.
>Clearly the real answer is that Tetris is played in a weightless vacuum, and that pieces are shot at a constant speed from somewhere offscreen.

Obviously not, since the speed increases as the game progresses (of course the planet could have increased its mass in the meantime).
Can someone explain this Q/A to me?

> Is there a safe way to prevent Mirror Go?

> A really sad result of talking to God about go would be that there is a way to just play mirror go and win. If that was all god did, it would be really annoying. If mirror go doesn't actually work, how does God defeat it? Do the variants where W is just not allowed to mirror fix the issue?

The first way I was aware of was that the primary player could surround the center. They'll capture the mirroring player's stones one turn before the mirroring player can surround theirs, and the mirroring player loses the stones they need to do a mirrored capture.

> they need a lot of investment from both parents in order to develop harmoniously

Completely agreed, I said nothing against this except that the assumption that the mother had to be the one to stay home was odd.

> Technically they could, but by that point they probably aren't very good at some kinds of care and bonding

No citation here, this really just seems like repackaging assumptions as fact.

> It's also not something that is appreciated by others, except maybe the mother, if she can get over their clumsiness and has the patience to teach them what to do. All in all, there's no benefit for the family if the fathers instead of the mothers work part time or stay at hole.

I am positive many fathers and close family would beg to differ.
These are great questions!! :)

> Can you treat all code like 3rd party dependencies?

Yes, but there are trade-offs. Discoverability, enforcing hard deadlines on global changes, style consistency, etc.

> Is it impossible to do these things with multi-repo?

No, but there are trade-offs to consider.

> If it's hard, is it "so hard" that it justifies the complexity?

Hitting the nail on the head; there are trade-offs :)

> Are these things necessary, if other systems get away without it?

There are many stable equilibria; open source ecosystem evolved one solution and large companies evolved another, because they have been subject to very different constraints. The organization of the open source projects is extremely different from the organization of 100+ engineer companies, even if the contributor headcounts are similar.

For me, the the semantic distinction between monorepos and multirepos is the same as the distinction between internal and 3rd party dependencies. Does your team want to treat other teams as a 3rd party dependency? The correct answer depends on company culture, etc. It's a set of tradeoffs, including transparency over privacy, consistency over freedom, collaboration over compartmentalization.

With monorepos, you can gain a little privacy, freedom, and compartmentalization by being clever, but get the rest for cheap; vice versa for multirepos. It's trading one set of problems for another. I'd challenge the base assumption that multirepos are "simpler", they're just more tolerant of chaos, in a way that's very valuable for the open source community.

I hope we've not been talking past each other, I really like the ideas your raising! :)

kmarc says>"and now he _wines_ about it."

"Whines! Whines!" NOT "wines"!

Whine - intransitive verb. (1)To produce a sustained, high-pitched, plaintive sound, as in pain, fear, or complaint.
(2)To complain or protest in a childish or annoying fashion.

To _wine_ is to drink wine!

I am whining in sense (1), although you are not here to witness my anguish at your language. I might be whining in sense (2) in this post, b/c I am fairly certain that no one but myself cares.

Otherwise, nice note on the good points of the subscription model for print cartridges.
While this seems (incredibly) scary it makes me think that this could be a huge opportunity for entrepreneurs (and some are currently undertaking it).

The fintech entrepreneur can carefully paint the picture of the dangers of the big 3 while advocating for smaller index funds for a smaller set of investors.

This smaller set of investors can have stocks based on their individual goals and interests. You just duplicate this over a lot more funds. The returns won’t be as high initially but if the entrepreneur can convince customers that this must be done it should help spurn new markets towards sustainability or carbon reduction etc.

Edit: plz tell me if I totally misunderstood the article.

Nobody had to lobby. I don’t think transit advocates realize how amazing car travel was back in the day. When I first moved to DC in 1989, there was no traffic. You could zip from Vienna to Foggy Bottom in 25 minutes. Even if you live in one of the apartments by the Vienna metro, it was almost an hour by Metro. If you had to take a bus, it was well over an hour.

Super fast, point to point trips are amazing. It’s still that way in much of the country.
I just remembered something related to what's discussed in this article. Back in the 90's someone discovered that taking a box of Dixie stir sticks and aiming the holes toward one of your ears would create really bizarre effects in your head.

First of course is the "eardrum suck" but there are also some other interesting illusory effects. I actually managed to find that very page about it: http://amasci.com/freenrg/audhole.html

People often feel disoriented and "stuffy" when they enter a sound proof room, like a recording studio or hearing test booth, or in a stadium, calm snow fall, etc where you don't hear echo / reverb of your own voice and other things around you. It's the same illusion again. Your brain really wants to experience the room ambiance, and gets funky when that information is missing.
Universities are incentivized to build buildings and destroy parking areas, because buildings make money and parking lots don't. Thus most universities are parking-constrained. The solution is to change that incentive structure, not to ration ever-dwindling parking spaces.
The thing I find fascinating, is not that Go was invented only once, but that it didn't spread to the West until 1880.

Having a usable fallback to smart tech's smartness is nice, but it can propose complications (and dangers) the manufacturer doesn't want to deal with because making the gear to deal with them then becomes cost prohibitive. The best thing is dumb tech, to which smartness can be added if desired by the user.
You just described M1 Finance (custom funds users can construct). Google Warren Buffett’s Long Bet about passive vs active fund management (he won the passive argument). Even sophisticated active investors are having a tremendously difficult time achieving passive returns net fees. If you’re not a sophisticated investor, I’d implore you to be cognizant of the challenges you’ll face attempting active investment strategies, especially if you’re investing retirement funds.

Passive index investing might not be perfect, but it seems to be the least worst option when evaluating fund costs and risk adjusted returns, and we’re aways off from significant second order effects.

I think one of the main points of the article is that for public transit to be worthwhile, a city must also work on zoning to increase density. Your point about the last “5 mile” problem is totally accurate for LA though, which as a New Yorker is always kind of funny — if I were to travel 5 miles from my apartment I’d practically be out of the city! I was just in LA earlier this month and every time I go the concept of not being able to walk to go about my daily business is pretty depressing.

LA doesn’t need to be as dense as New York or Paris, but if transit is to work, density needs to come with it. Otherwise it’ll always just be a massive suburban sprawl built for cars and not humans.

The rationales is that you are benefiting from that service (public information) indirectly (other citizens make more informed decisions) even though you don't use it directly.

And, realistically, which household does not own a device that is able to receive a video via a web site?

BTW, you don't need to pay the Rundfunkbeitrag if, among others:

You asked about harm. Expectation of privacy is a different matter. And they might expect privacy due to wearing masks - why is it okay to regulate those, but not facial recognition? While I'm against regulating facial recognition, I'm at least aware of the harm it causes.

> If you're a peaceful protester, it shouldn't matter.

It shouldn't, but it does. If the government and corporations were so perfect that it wouldn't matter, you wouldn't be protesting in the first place.

This is a pure ad hominem, and not a very good one either. The motivations of an imagined 'some' people are irrelevant to the harms of surveillance and facial recognition.
