It sometimes amazes me how utterly random problems like this end up being their own fields in mathematics. This ended up being a pretty fascinating problem, but coming up with an arbitrary equation like this and then checking to see if it satisfies yet another arbitrary requirement doesn't seem very difficult to do. Am I completely missing something here?

It's a risk any time I speak to you, because a large part of my life is HN, and speaking to you risks another penalty. I didn't mean it as an accusation, it just seems to be the mechanics of me-speaking-to-you.

I also apologize for quoting a sentence that you cut. That happened to me earlier, and it's always frustrating, even if it was unintentional.

My point was, your comment seems to be mistaken in a revealing way. If it were true that YC was biased, then your editorial decisions wouldn't be able to influence anything in relation to the bias. The bias would already have an impact on the startup pool that you can select from.

In other words, your decisions about HN's "Meet the Batch" threads seem unrelated to the question of YC's alleged age discrimination. But you felt that your decisions were related, since you were saying "We don't select for age" in regards to the Meet The Batch threads.

Bias is something that you can't force someone to care about. I'm hoping that it may be a lightbulb moment for you, as it once was for me. It's never any fun to be a part of an organization accused of some form of bias, but asking yourself "Could it be true?" is a mental exercise that personally I found helpful.

That said, you were correct that this commenter posted those startups without knowing the ages of the founders. It could be possible that those startups have older founders. But no one seems to be quite sure. It's lame of them to make an insinuation like that without knowing the ages of the founders – burden of proof – but it's also worth considering whether it's true, even if it was a lame accusation.

Anyway. I didn't say any of this to put you on the defensive. That'd be the opposite way to change your mind. Just think it over a moment, is all I ask.

EDIT: After re-reading this chain, perhaps I'm off the mark here (a common theme). From my perspective, it sounded like someone was saying "Well, it might be true; these startups do seem pretty young and trendy..." and then you were listing reasons why that was mistaken.

It sounded like you didn't necessarily care about whether YC is age discriminatory. My goal here was to convince you it may be worth caring about it.

If you already do care about that, then never mind. My mistake. I see now that your point about editorial decisions was an expansion of a different train of thought.

One last point to give a moment of pause: If you list N random politicians, most of them will probably be pretty old, because politics is biased against youth. If you list N random YC companies, will the ages of their founders tend to skew younger or older (relative to the proportion of those age groups that apply)? That might be one way to investigate the claim.
Humans don't always react rationally in code red situations though. Right now the irrational fear of nuclear power is stronger than the fear the average person or politician has of climate change. Doesn't mean that the climate change situation isn't dire.
So it's easy if all countries agree. If that is not the case you need to find out how much carbon from the ground was used in each item at your border. At that points it becomes rocket science?

Unfortunately markets are not good at accounting for those kinds of external risks (but they could be with the right incentives, like a carbon tax.)

It's a tragedy of the commons scenario. I don't understand why politicians don't just do the hard/right thing. Supposedly that's why we have them. If they always just do the popular thing we could cut them out of the picture and go to direct democracy. I'm not advocating for that, but we need politicians to step up and do their jobs competently.
> then you need ~3x the delta-v to get to Mercury compared to the moon. [..]
> In theory, you could just use a rocket that's 3x as powerful as the Saturn V to get enough fuel into orbit to get to Mercury via a direct route

I'm a bit confused. I have a vague memory that due to the Tsiolkovsky rocket equation the amount of fuel needed to reach a delta-v grow exponentially. How is it possible that you need a 3x bigger rocket to reach 3x the delta-v?
> For example in the manufacture of solar PV, the solar panels themselves are counted, but since the companies manufacturing and processing the silicon need for these are in China selling to other Chinese companies, that is not counted even though all those fossil fuels used are used exclusively for the benefit of American companies.

This is simply inaccurate. US consumption CO2 numbers account for US purchase of solar panels.

Though I appreciate that there are some link here, you are still making backwards-looking statements rather than stating limitations about what could be. For example, this link:

https://ourworldindata.org/grapher/global-energy-substitutio...

Is of what was in terms of energy. Will it be that way in the future? Only if we let corruption and entrenched fossil fuel interests prevent cheaper options from being deployed.

Renewable expansion is just barely getting started. To declare "game over" already is fatalism and not founded by any sort of data.

Dollars are not CO2 emissions. CO2 is emissions. Our economic systems are constructed by law and convention, and technology is completely changeable.

I see lots of feelings and emotions in your post about frenzy, but we need all that frenzy. We need action and change, desperately. Economic collapse will not save us, because emitting 25% of our current emissions is not good enough.

The only solution is compete transition of the economy in all sectors. Massive change. I say get on board or get out of the way.

The price for an IBM PC isn't correct (or at least, it doesn't match the infographic). The little picture shows a PC with two floppy disk drives and a monitor; the price quoted ($1565) was for the 16K model with no floppy disks and no monitor.

(And no hard drive, either). This means that the PC would boot into BASIC, and you could save/load programs and data to a cassette recorder. It was the absolute minimum configuration and wouldn't have been very useful.
I wonder if in terms of GC Go still has an advantage over Java now that ZGC and Shenandoah are here. Though from what I understand you have to choose between GraalVM or one of the new GCs/some heavy reflection.

Go is a bit like this friend that you like to hang out with because he's fun and great for small talk around beers, but that you find boring or painful when you want to have deeper conversations, and that you don't want to go on vacation with.

That's a really good way of describing my feelings too, though I would describe it as a collegue more than a friend. I can see why this could be a good thing for people though, at some point you may want to do day to day work with a reliable collegue and not a friend.

I strongly support nuclear, but there are key benefits to incorporating more transmission as wind and solar are added to the grid.

Both utility scale wind and solar are the cheapest forms of energy. But they occur in concentrated, geographically changing areas. I.e. a high pressure system creates a cloudless sky, great for solar and but wind. And 1,500 miles a way a low pressure system is creating tons of wind but no solar.

The most cost efficient way to balance such a grid is to use large amounts of transmission to 'smooth out' these geographic correlations - moving the solar and wind to places where the other is absent.

Only large scale transmission can create a full transmission to a zero carbon wind with about 20% of the total provided by nuclear. You can add more nuclear, but then it increases the total cost of the zero carbon system. [1]

No sure if the parent (grandparent?) would find this helpful: but here’s the setup I use that provides a cool amount of options.

I use a Yamaha receiver (R-N803) that has their MusicCast software on it. And I use these various inputs:

- CD

- Phono

- USB. A little teensy usb loaded with music I’ve collected for the last 25 years - however, I’ve cleaned it up so it’s not filled with random things that makes my wife go “what is all this stuff! I just want to see MY music!”

- I have a Navidrome server running on a pi, with a hardrive connected to it. It basically contains the USB + all the other random stuff. This is played via the bluetooth input and Play:Sub app on my phone.

- Likewise I play the bandcamp app via Bluetooth through the receiver, and spotify as well (I mostly use spotify for listening to the back catalogs of established artists).

- Net Radio. Access thousands of radio stations, worldwide, that stream their service. It’s pretty cool!

There’s more. But, point is the setup is cool and diverse and it’s pretty easy to use.

(A mistake above: it should be "we see it's nothing other than (\x, f (x x)) (\x, f (x x))")

While we're here, another cool application is that quines exist. I'll give a way that misuses the theorem (though in a correctable way) to derive a quine. Consider the meta-function quote : L -> L that takes a lambda expression and produces a representation of it (like the representation used by the self-interpreter two comments up). I say meta-function because this isn't implemented by a lambda expression itself. Applying the fixed-point theorem to the same I : L -> (L -> L) with quote, if it were an actual lambda expression, we'd get a lambda expression s with s = quote s. That is, the expression s would evaluate to its own representation!

The fixed point is purportedly (\x, quote (x x)) (\x, quote (x x)), which doesn't make sense since quote is not a function. However, suppose q is a lambda expression that takes representations of lambda expressions and quotes those, so it satisfies the equation q (quote x) = quote (quote x) for all lambda expressions x. Also, let app : L -> L -> L be the constructor for application. Then (\x, q (app x (q x))) (quote (\x, q (app x (q x)))) fixes the problems and is a quine:

(\x, q (app x (q x))) (quote (\x, q (app x (q x))))
= q (app (quote (\x, q (app x (q x))))
(q (quote (\x, q (app x (q x))))))
= quote ((\x, q (app x (q x)))
(quote (\x, q (app x (q x)))))

(A way to do this all above board is to use the self-interpreter and somehow use q in the thing we're trying to find a fixed point of.)
I was also 8 or 9 years old, and didn't really understand the big deal. On some level, I knew that my vision was different than other kids, but when it came time to test it, I also had a desire to "beat the test." If it seems childish, that's because it was. :)

I'll buy that Little Wars is simple (from my understanding).

Kriegspiel, however, was very far from simple. It was just focused on battle simulation.

From my understanding, it was intended to be played by each side (either individual or team) being in their own room with their own map of the battle. Communication would go to the referee, who would run "reality". The referee would have a map and use charts, tables, dice, and pure fiat to sent information and update the state of the game to the players. Plus the game was played to a real clock. An ideal setup would have the opposing generals only communicating with the referee by means of runners, to simulate the telephone effect.

I really can't call a game that requires no less than three terrain maps and three rooms to be "simple". Especially when you see the dice the game uses.
One again showing that the Plants vs. Zombie developers were very prescient.

The question we must ask ourselves is who were the true heros of those games? The plants that had developed to the point of nearly nuclear destructive capabilities?

I mean if browsers started doing something like marking sites that didn't have OCSP stapling as potentially insecure, or otherwise pushed for it.
The YC application requires you to list your age, it does not ask if you are vegan. I think it's completely legitimate to ask why age is explicitly included in the application process. I also think it's an interesting discussion whether it is okay that things like requiring relocation unintentionally bias against age (I think it is okay, but it's an interesting discussion nonetheless).

I'll grant you that the title is total click bait, and I don't think it's likely the OP specifically was rejected due to ageism. But I don't think that was his main point.

Are there any "open" search index initiatives going on?

Like a curated wikipedia/openstreemap of internet search indexes (with ignore-lists like uBlock has for ads)?
I fully realize the impossibility of a handmade search index for the entire web, the internet is just too impossibly large and ever changing. I'm more thinking of subsets of various topics of interest. Different communities could pop up that made specialized crawling algorithms for very specific topics and you could subscribe to those indexes for a very personalized search experience. A mix of automatic classification, indexing combined with hand-tweaked tagging and weeding out spam.

Over time you could have a pretty "broad" search engine - kinda like how OpenStreetMap was initially terrible (coverage wise) but is today extremely competitive with the big guys.
With it I could subscribe to or possibly even aggregate/proxy other indexes into a personalized search system. That way I could make a super specialized search that only searched indexes made for information search on technical topics and have another index explicitly filter out unwanted spammy websites.

Some "pre-index" on the search front-end could intelligently decide which indexes to query based on your search string. If you are dissatisfied with the indexes it chose to query you could manually tweak it and redo the search.

At the very least it would be awesome if search engines had a way to submit an "ignore-list" - an index over known crap/spammy websites. It's not feasible for me to keep adding specific ignored urls to a search term. When I search for images online I would prefer to ignore Pinterest by default.

It really irks me that when searching for information that Google defaults to thinking I'm looking for a product to buy. Sometimes I would just prefer to exclude ALL websites that generally only acts as a retail/webshop for goods. That fine grained search method is just not possible today.

There are a lot of small private holdings within public lands. They should receive some property tax relief, in exchange for understanding that the forest around them is going to be managed naturally.

That doesn’t mean that their property won’t be defended as much as possible, just that stopping the entire fire itself won’t be the goal.
Note the point I made elsewhere: that you’re likely to draw on your “cash” emergency fund in times of market downturn. (E.g., you lose your job because of layoffs due to a market crash.)

Having that “emergency fund” be invested in the market means you will have “buy high/sell low” events.

For sure some people can afford this and just like to live dangerously, of course.

I'll turn that around and ask specifically why that's not possible.

It would require a better interconnected grid, overbuilt renewables, and plenty of storage with some level of on demand generation like gas. A good percentage of baseload power like hydro and nuclear certainly help, but it's not required.

It's just a matter of how much are you willing to spend as opposed to something that's physically impossible.

I believe renewables + grid scale batteries are already cheaper than new nuclear and much lower risk and much faster to deploy. The momentum is in favor of widening that gap.
