Put your notes in OneNote, and divide them into 4 or 5 high-level categories (1000,2000,3000, etc). Then split those thousand groups into hundreds groups, tens groups, etc. Something magic happens to your brain when you start using numbers to group things. Not sure what it is, but overtime you’ll find yourself using the number and not even saying the title anymore. Also having dedicated buckets for things relieves a tremendous amount of anxiety. It takes a while to build and it’s incredibly an unintuitive thing to build out, but it really helps. Check out schemes and the top level pages on wikipedia, or maybe various classification systems.

An HN recommended book The Ancient Art of Stoic Joy by William B. Irvine comes to mind when reading this. Here's a neat quote:

We should use our reasoning ability to overcome negative emotions. We should also use our reasoning ability to master our desires, to the extent that it is possible to do so. In particular, we should use reason to convince ourselves that things such as fame and fortune aren’t worth having—not, at any rate, if what we seek is tranquility—and therefore aren’t worth pursuing. Likewise, we should use our reasoning ability to convince ourselves that even though certain activities are pleasurable, engaging in those activities will disrupt our tranquility, and the tranquility lost will outweigh the pleasure gained.

The idea of practicing will-power, learning to decline known-pleasurable outcomes as a form of practice, is a well tested idea in stoic philosophy. The practice seems to suggest that there is an energetic ebb and flow of indulgence that can be countered by refining one's ability to reason.

The Floyd Steinberg error diffusion dithering algorithm can use a boustrophedonous scan order to eliminate the diagonal geometric artifacts you get by scanning each row the same direction.

https://en.wikipedia.org/wiki/Floyd%E2%80%93Steinberg_dither...

"In some implementations, the horizontal direction of scan alternates between lines; this is called "serpentine scanning" or boustrophedon transform dithering."

I implemented some eight bit cellular automata heat diffusion rules with error diffusion, which accumulated an unfortunate drift up and to the right because of the scan order.

Rudy Rucker pointed out the problem:

http://donhopkins.com/mediawiki/index.php/CAM6_Simulator

"Rudy Rucker: I feel like you might have some kind of bug in your update code, an off-by-one thing or a problem with the buffer flipping. My reason is that I see persistent upward drift in the action, like if I mouse drag a blob it generally moves up. Also the patterns appearing in the blob aren't uniform. I mean...this IS supposed to be the 2D Rug rule, isn't it?"

So instead of scanning back and forth boustrophedoniously (which wouldn't eliminate the vertical drift, just the horizontal drift), I rotated the direction of scanning 90 degrees each frame ("spinning scan") to spread the drift out evenly in all directions over time.

https://github.com/SimHacker/CAM6/blob/master/javascript/CAM...

// Rotate the direction of scanning 90 degrees every step,
// to cancel out the dithering artifacts that would cause the
// heat to drift up and to the right.

That totally canceled out the unwanted drifting and geometric dithering artifacts! That made it possible to cultivate much more subtle (or not-so-subtle) effects, like dynamically switching per-cell between different anisotropic convolution kernels (see the "Twistier Marble" rule for an extreme example).

It's confusing that it seems like more than 1% of the population in a given area are buying houses that demand you're in the 1% of income to be able to afford; until you realize there are no restrictions (or easily circumvented ones) on foreign ownership. There are LOTS of wealthy people in the world.
A lot of big games are also turning out to be so compromised by microtransactions and related mechanics that the only sane response is apathy. Look at how a modern Ubisoft game is structured... it's really ugly. I have a friend who plays For Honor, and that game is truly half-assed, with wretched netcode. It's also a massive time-grind, with "loot boxes" to boot.

Gaming is just becoming an endless series of thinly disguised Skinner Boxes and slot machines, designed to turn you into an ongoing income stream.
I only skimmed the article, but would creating something similar to the homestead act, but with regards to low population residential areas be a workable solution? Population dispersal seems like an interesting topic.

> why couldn't they have standardized a protocol for a server to get updated certificates from the CA?

That's essentially OCSP :-)

In general there's not really a concept of an "updated certificate". A certificate is good if the signature matches, the subject on the cert matches the server, and the current time is within the certificate's validity period; otherwise, the cert is bad. If someone steals a certificate, the website fixes this by telling the C.A. to revoke the certificate and by serving a different valid cert – my old employer kept a second valid certificate lying around in order to minimize downtime in the event of having to kill the main cert. OCSP is a way to effect the killing of the bad certificate. But in the absence of OCSP or some other revocation mechanism both certs are still good.

> if the CA can sign OSCP responses for millions of visitors, surely they can resign a certificate every y days.

I haven't worked on this stuff in a few years, but historically OCSP resolvers were notoriously unreliable and often down. That's a huge issue for a security-critical path, because you're forced to "fail open" (which defeats the whole point of having OCSP in the first place) or render a wretched experience for your user. One big reason OCSP stapling exists is to work around C.A. OCSP resolvers' unreliability.

I'm not sure if it's resurrecting, or just improving it's image, either way it's welcome. Still, it is sad that it is so focused on one game: D&D. It's a decent game, particularly fifth edition, but I can't help finding it a bit... um, artless.

Which isn't a problem, sometimes that's fun. But when there are so many amazing and sophisticated RPGs, with game mechanics that expand the form and support interesting play, it is a shame that DnD still gets all the focus.

I'd love to see more love for 'Night Witches', 'Dogs in the Vineyard', 'My life with Master', 'The Beast', 'Hillfolk', 'The Clay that Woke' even 'Apocalypse World', or 'Fate'.

It's like programming languages, sure you can do anything in D&D (≈ Java, perhaps?),
but other games have different strengths. Sometimes, being into non D&D RPGs can feel like people saying "there's more than one programming language?"

Excel is also extremely robust. You can, for example, do VLOOKUP between tables that are ~10K columns by 100K rows. And it just does it. And pauses/restarts calculating, if you need to tweak something. But Calc? It just freezes, and eventually dies, and then must rebuild the file after restart. Which may end up being impossible. Indeed, Excel will do pivot tables that choke MySQL :) And it uses multiple processors.

I was on the Credhub team for a while. When you begin to assume that you have (1) an always-on credentials service and (2) that it can serve multiple sides of credentialling (eg, service broker adds a credential, application fetches it), you get to do more aggressive cred management.

Yes, certainly - I think the thing I mean doesn't conflict with the thing you mean.

Referral programs will pretty obviously bring your hires similar to the hires you already have, with all the attendant problems. College insularity, but also demographics and even specializations. What I was thinking about was more specifically finding strong candidates from populations that don't look great.

Maybe State University has a weak CS program, but a handful of really good candidates. (This is probably the case for any weak program of sufficient size.) Those candidates probably won't be obvious on paper unless they're hyper-motivated, because weak programs lead to limited opportunities and uninformative grades.

But if Jess from State University does Google Summer of Code and makes something awesome, maybe she gets a job. At that point, Google hands her the referral form and she can pick out her strongest classmates better than any recruiter could, even if they haven't done anything flashy. (My experience, at least, was that the top students are at a minimum aware of one another.)

So it's not going to solve a demography problem; if your direct hires are 50% Stanford, your referrals will be too. But a lot of those Stanford referrals might be people you'd reach anyway, so referrals are valuable in inverse proportion to the ease of other recruiting. The harder it is to spot which candidates are good, the more benefit you gain from asking their peers.

What was done to prevent a housing collapse? I am under the impression the government focused on preventing a banking institution collapse, which is different. That money was given to offset the liabilities caused by the housing collapse. If Bob was foreclosed, he was foreclosed because he didn't make his payments, at which point his house was put on the market. The banks collapsing wouldn't put more houses on the market than before, it would just mean that a different financial holding company would be selling the houses. So to prevent a housing collapse the government would have to make it easier for Bob to make his payments, but as far as I know the government didn't do that.

Or perhaps you are talking about something other than the bailout like interest rates, in which case I would still be curious what you think would have caused the collapse

If you want to buy a phone with a replaceable battery, then do that. Why force everyone to put up with the extra bulk and weight? And at least with apple, replacing the battery does not require replacing the phone.
Right - like I said, fighting equality of opportunity is worthy and must be pursued relentlessly.

What seems to be happening (the impression I get) is something analogous to this:

I have a game released on two mobile platforms - android and iOS. The iOS players are disproportionately scoring better than the android players.

Some are suggesting that the server is bugged/programmed to give iOS players better scores. I reject this.

Some are saying that the android user experience has conditioned those players to be satisfied with a low score. I reject this.

Some are saying iOS players are superior because they bought an apple product. I reject this.

My opinion that it is likely that the android release has a lot of performance issues which impede the player's ability to get a high score on that platform. I test this out by doing things like getting an android player to play on an iOS device, and checking if their performance improves. I do the reverse and check accordingly too. I do various tests on fps, input lag, etc.

If my experiment fails to show anything conclusive, I should be open to re-evaluating some of the things I rejected, but I refuse to do it out of zealous belief in my hypothesis. The answer must be optimization, I insist.

If my experiment succeeds, I should tweak the android code till the disparity goes away. Instead, I just hardcode +500 to the android scores and pat myself on the back.

There seem to be cases where the diversity disparity is "solved by hardcoding", and other cases where the data doesn't support the hypothesis, but there is an ardent refusal to accept it, as if it would be blasphemous to suggest otherwise. These are pretty much the only things I take issue with.
I think it's mostly that you have an unusually good experience (or take on it). HOAs are seriously hated by a lot of people. Google "HOA hate", and check out the results.
We have... in a sense. There are number systems wherein 0 is treated rather like dx in terms of being a formal entity upon which algebraic manipulations can be performed; in such systems we can say for example that sin(0)/0 = 1 while sin(0^2)/0 = 0.
> I think people are massively underestimating the TAM.

While I agree, my only criticism would be that the "old" data center market is effectively consolidating to commoditized hardware. In other words - we have less idle CPUs in data centers and the diminishing returns of Moore's Law is hitting. So while the new wave is positive, the underlying revenue stream may not be consistently holding.

Non-classical foundations, violently non-set-theoretic, perhaps could cope with this while allowing numbers greater than six.

Pretend there is a non-commutative set theory where observations of membership do not commute akin to quantum mechanical systems. Perhaps it would be possible for a model of such a theory to have all finite sets as valid states, but sets of cardinality exactly 6 are forbidden.

Just extremely sketchy hand waving but it might make sense. Certainly classical mathematics is out the window.
My Governor Is Really Trying about Roads by Pius Adesanmi
This article is trash and I'm stunned that it would be hosted on a harvard.edu domain. Whoever posted this should be ashamed of themselves.

Fallacies, lies, and generally ignorant opinions include
* Pretending the US was a more market-oriented economy in the past (which is not true)

* Comparing the housing situation 100 years ago to that of today. There are many reason why america in 1917 is very different than the america of 2017

* Literally cites a Wall Street Oasis forum post as a source on why we should not subsidize housing for the poor

* Income inequality is (obviously) a huge component of housing not being affordable (especially in urban centers) and this is dismissed using an obvious straw man argument.

One of the biggest housing subsidies is the mortgage interest deduction which is almost entirely captured by wealthy homeowners and financial institutions. It also definitely pushes up housing prices. If the author of this post had any knowledge of the housing market they would have brought this up.
Yeah. I won’t play DND because it’s too open ended. I simply don’t want to commit that much time to a campaign.

But there are board games like Mansions of Madness that use an iPad as DM. You can play as many or as little of the scenarios you want. Then DM later if you get into it.

There are also sandbox type board games. There is no DM but you get to decide what you want to do.
My son was so good at reading lips that we'd play a game where we only mouthed words and he'd tell us what we "said". In school we let the teacher know he needed to see her say the words on a spelling test. In those younger years that was the only way he could tell the different in some sounds. The big one I remember was "th" and teaching him to look for the tongue on the front teeth.

As he is getting older he relies less on seeing lips. I'm hopeful at some point he'll outgrow most issues.

I like this idea. I think it strikes a good balance between the rights of both sides and provides incentives for opening things up (which I believe is important to consumer freedom). But if a company doesn't want to open it up, they still have a reasonable path forward.
You're correct in some ways but, I think, missing a few key points. For roughly 15 years before AWS, inexpensive shared hosting was available.

From a bootstrap perspective, there was little cost difference at the beginning. The main difference was in the middle stage: scaling. After a bit off success it was still possible and practical to scale until you outgrew the ability of a single dedicated server to handle a specific task. Until then, you could grow and scale with little difficulty from a shared server, then dedicated, then shunting functionality to individual dedicated servers, e.g., web sever, database, etc. Yes these cost money, but ig you were bootstrapping then you only got to that point after you'd passed through the nearly free-per-month shared stage and, abd long after revenue flow began.

Scaling beyond that was absolutely way more difficult in terms of tech knowledge and cost. Modern AWS makes that scaling much easier, but the pre-ramen profitable stage was not much if any more expensive.

The key cost that was then and still is the biggest, in my opinion, is opportunity cost. A hundred bucks a month then or now, with or without adjustment for inflation, is nothing compared to the opportunity cost.

As a more general rebuttal of the sentimemt expressed, I'd offer up "started in my garage" businesses of all sorts, then and now. Those whose primary initial input is never cash but sweat equity and grinding out the details and execution of an idea.
I think a lot of it is that pay scales on cost of living. It allows prices to go to crazy amounts and also disincentives moving to cheaper areas. If pay didn't scale on cost of living then tons of people would move from those high cost areas. I'm making 70k a year but I'm putting 14k into my 401k and investing an additional 14k each year (saving up for a down payment on a house) and that's while having hobbies and travelling some

1. If you want to apply, please submit your application online by 8 pm PT on October 3. Groups that submit early have a small advantage because we have more time to read their applications.

2. On October 24, by 10PM, we’ll invite the groups that seem most promising to meet us in Mountain View in early November. We’ll reimburse reasonable travel expenses.

Being they said 8pm PT on the previous line item, I would guess that it's 10pm PT for the invitations. So basically, three more long hours to go... Good luck!

In particular, ℤ without 6 is not an algebraic field, because fields are closed under addition and multiplication.
