> Doesn't this partly fall into the weather Vs climate difference? I can't run fluid dynamics in my head but no matter how much you shake up the box once it's on the table I can say "I think the water/oil/honey will end up at the bottom".

Not in the slightest. For example, the output of a numerically unstable [1] algorithm, run on 64-bit floats, can diverge arbitrarily from the output of the same algorithm run on real numbers with infinite precision (which computers can't do). Often this will lead to obviously wrong outputs, but not always. There are numerically-stable versions of most of the workhorse linear algebra algorithms, but (1) sometimes it's possible to use a faster, numerically unstable algorithm, and this is a matter of judgment that can be mistaken and (2) it's easy to introduce numerical instability via subtle bugs, or even via the exact arithmetic steps you use to calculate a result (in particular, trying to add or subtract two numbers of very different orders of magnitude is a big no-no).

We use Aurora Serverless and this is a sorely needed feature for us. We get large spikes of traffic that also cause large increases in connections to our DB, but Aurora Serverless cannot scale fast enough to cater for this. Unfortunately it doesn't seem we can enable this proxy for serverless clusters.

>Null hypothesis: this is not the case.

>The p-value is 1/32, so the null hypothesis is rejected.

This is incomplete. You need to define a test statistic and know its distribution under your null hypothesis before you can come up with a p value. What's your test statistic here and how is it distributed?

If you define your test after seeing the data, of course you can come up with an arbitrary p value. Choosing a distribution for your null to make it fit an agenda is just like choosing a distribution for your prior after seeing your data to make it fit an agenda.

You could say your prior is a delta function around HHTHT after observing it and get arbitrary evidence, but anyone reading your paper will find it unconvincing, just like anyone reading about a test statistic like this will find it unconvincing.

> Of course, don't let skepticism stand in the way of your belief system, but i highly suspect that'll be a problem for you.

Interesting article, thanks. Unfortunately your first and last lines are unkind, snarky name-calling, to choose a few of the ways they seem to break the HN guidelines. And "I'm going to guess you're on the X, Y, Z crowd.." seems close to Schopenhauer's Stratagem 32:

If you are confronted with an assertion, there is a short way of getting rid of it, or, at any rate, of throwing suspicion on it, by putting it into some odious category; even though the connection is only apparent, or else of a loose character. You can say, for instance, "That is Manichaeism" or "It is Arianism," or "Pelagianism," or "Idealism," or "Spinozism," or "Pantheism," or "Brownianism," or "Naturalism," or "Atheism," or "Rationalism," "Spiritualism," "Mysticism," and so on. In making an objection of this kind, you take it for granted (1) that the assertion in question is identical with, or is at least contained in, the category cited - that is to say, you cry out, "Oh, I have heard that before"; and (2) that the system referred to has been entirely refuted, and does not contain a word of truth.

>We were playing worldwide economics on easy mode: as if we were the only ones that had modern technology and fully functioning infrastructure, while all other countries wanted our goods. This is why it is bizarre to draw any conclusions about taxes or any other economic principles from this very unique period of time: you could probably put in place just about any law and still have the United States be ridiculously successful.

IIRC Pickety made this exact point in his book Capital in the 21st Century. Looking back at that time period as something to emulate or get policy ideas from is misguided for this reason. Instead of thinking of it as "a time of enlightenment when the people fought the billionaires and achieved utopia" it would probably be better to think of it as "a historical aberration which will probably never happen again".
TFA article does say. They looked at 17 forecasts drawn from 14 models. You are the one who implicitly believes they are lying about that and only reporting 17 out of some huge unknown number. The reality is that the vast majority (>99%) of climate change research does not produce the type of forecast, or really any forecast at all, that one could do this analysis on. Therefore, the 17 forecast number is actually very easy to believe.
For anyone else who spent 10 minutes trying to find a link to pricing from this page and failing, here it is:
https://aws.amazon.com/rds/proxy/pricing/

Free til the end of 2019, 0.015 per vCPU (of the underlying RDS instance) per hour the proxy is enabled. So it is not scaled down to 0 when not in use. For comparison, a t3.micro (2 vCPU, 1gb ram) is 0.0104 per hour. If you're a big project it might be worth it, but just keep in mind rolling your own proxy or using the RDS serverless APIs are cheaper options.
Thank you. I looked the issue up and learned that legally copyright infringement is distinct from theft. I still think the term is a good inexact colloquial approximation.

However, I couldn't find anything to support your assertion that copyright violation is a breach of contract. It doesn't make sense: breach of contract requires an agreed upon contract to be breached.

Also, cite for the idea that copyright law hurts the poorest the most? Haven't seen that before.
> Bayes' formula has no place to put for things that could have been observed had things turned out differently, but which didn't actually happen.

Sure it does: you have to calculate the probability of your data given the hypothesis. Doing that requires considering all possible outcomes of the hypothesis and their relative likelihood, not just the one you actually observed.

> If your prior was that a fraction p of the children would be boys, the odds of the observed outcome would be p^6 (1-p).*

The prior would not actually be a single value for p; it would be a distribution for p over the range (0, 1). The distribution I described was a narrowly peaked Gaussian around p = 0.5, though, as you point out, that might not be the correct value for the peak (see below). However, for illustration purposes, it is much easier to talk about the (idealized, unrealistic) case where your prior is in fact a single point value for p.

However, in order to calculate the odds of the observed outcome, as I said above, you don't just need to know the prior for p. You need to know the process by which the outcomes are generated, according to the hypothesis. The odds you give assume that that process is "bear seven children, regardless of their gender". But that is not the correct process for the actual decision procedure you describe your aunt and uncle as using. That process won't necessarily result in seven children, and the odds of the actually observed outcome will change accordingly.

> a Bayesian with access to actual population data would be aware, as you aren't, that globally we average 1.07 boys to each girl at birth

Depends on whose data you look at and over what time period. But I agree that the best prior to use in a given case would be whatever distribution you get from the data you already have, and yes, that might not be peaked exactly at 50-50.

I switched my work and personal device Firefox settings to have ddg as default. I then use the !google bang to search Google if needed. Usually this is for retail queries. This simple step allows the best of both worlds, although the privacy tradeoff is there cause I'm still using Google.
GPS is one of the most amazing technical onions I've ever dealt with. I've just been scratching the surface of it with understanding positioning for a robotics project. I kind of wish I had an opportunity to do more paid work with it. But it seems to be the realm of PHDs.

One of StarLink's biggest overlooked opportunities I think is radically re-engineering a GPS like system that can work indoors and outdoors as well as offering some pose estimation capability. It would make implementing robots way easier.
I don't know much, and sorry for a terse repl (If I try to write out proper sentences and look up references this may take me more time):

- You can search for comments by modern scholars about it; e.g. search for [witzel "tape recorder"] on the web / in Google Books to find some quotations of a memorable analogy.

- You should find some material online in connection with "The Tradition of Vedic Chanting" being part of UNESCO's "intangible cultural heritage" lists / "Masterpieces of the Oral and Intangible Heritage of Humanity". I believe there were some documentaries produced. haven't looked closely but these sites look related: https://ich.unesco.org/en/RL/tradition-of-vedic-chanting-000... / http://vedicheritage.gov.in/vedic-chanting-unesco/

- There's some good information on the Wikipedia article at https://en.wikipedia.org/w/index.php?title=Vedic_chant&oldid... e.g. for every string of the form "abcd..." one learns not just "abcd..." but also "ab bc cd..." and "abbaab bccbbc cddccd..." and some learn even more dizzying schemes.

- There are some documentaries on these schools, e.g. https://www.youtube.com/watch?v=5FxYydNlrFk (there are a few more longer ones).

Put your own DNS server in front of it that resolves the canary domain, I guess.

The absurdity of rolling a DNS server solely to unblock a domain blocked by an upstream DNS server specifically so that an application can resolve that domain and consequently not actually use your DNS server is not lost on me.
Sad to learn that Dr. James Spilker has passed away this year. I worked with him at his company Stanford Telecommunications from 1983 until 1992. He was quite a character back then and was an avid body building enthusiast. Sometimes he'd come to work all buttered up with tanning lotion.

I wonder if there are common best practices on throttling growth for a lifestyle company or bootstrapped startup? I guess it can be as simple as turning off new registrations for periods of time or only allowing invitations at arbitrary times. Has this worked well for any SaaS businesses? Once you hit your financial goals, it could help forestall burnout, but I suppose there's a lot of risk there too - if there's enough unmet demand, someone could replace you.
... but if you think, "hey, so the models could be wrong, how reassuring", think again. It's just as likely that reality is worse than predicted.
I can't tell if they are claiming 4x efficiency over the other rim generators. Seems unlikely. The alternative is they make 3-4x more drag, which would be ok if you need that much power. Google Maps does burn quite a lot.

Four years in development? Maybe they got an engineering degree in the meantime?

It's maybe a little unfair to say it's just a regular generator with a supercapacitor. They must have a $.50 power converter in there, and a microcontroller to negotiate USB charging voltage, maybe $1.

But tooling for plastic molding is super expensive for low volumes.
It's also true of later 911s as well. I did carbon fiber bodywork for a PCA club racing team in college, and I definitely experienced it in some of the water cooled 996s. Some of the traction control methods reduced it a bit, but Porsche knows that they can't get rid of it entirely without changing the balance of the car (or alienating fans).

The 928 and the 944 were also front engine with a rear transaxle, which evened out the weight distribution quite a bit, and that alone mitigated a lot of the lift throttle oversteer. I loved the handling of both of those cars...you get the 50/50 weight distribution of a mid engine car, but the handling is so much more stable and predictable because the weight is at the ends of the car. Too bad they were about as reliable as octogenarian flatulence.
Yeah. It's a shame how few people invoking shell commands use tricks like "--" to suppress option parsing and "./*" to suppress bad globs. :-(
> That is incredibly monopolistic behavior because it can't be reproduced any other way.

Monopolistic would be Google making publishers integrate directly with them to enable prerendering like Apple News or Facebook Instant Articles. AMP pages can and are consumed by link aggregators other than Google, so they are very specifically not abusing their monopoly by telling publishers to use AMP.
No. No they did not. This is wrong.

That's just because all things we like that are also good for us, we already do them.

Well that's quite the pigeonhole, and I will not duck my head to enter.

I refute your premise as fundamentally un-American. As a business, you are under no obligation to compete for government contracts. That notion, IMO, would be a sure sign of a broken democracy. I'd describe such a policy as authoritarian. It's happened before, under martial law; a constitutional mechanism to temporarily suspend democracy. It's happened elsewhere, under communist regimes.

Of all things, the third amendment informs how the founders might address this. Don't see that one every day.
Thanks for sharing that Mr Koch. We’ll be sure to file your response for appropriate consideration.

Privatisation of essential infrastructure leads to price gouging, service failure, and cartel behaviour. There’s zero incentive for corporations to provide cost effective or reliable solutions to problems. The actual incentive is to raise the cost of the service you need to the point where you can barely afford the service, but aren’t motivated to either do without or start your own business to compete.

This is terrible misinformation.

The rules in AMP designed to speed performance are extensive.

Lots of things you can do in HTML - linked style sheets, synchronous third party java-script and ad frameworks etc etc are heavily restricted. There are size limits even on the inline CSS I think or even on the separate web worker javascript even animations are restricted so they can be accelerated.

The speed increase is not just because of preload. Turn on dev tools and look at network round trips / page size / CPU usage on an AMP vs nonAMP page.
Well, and for 25-30 years, everyone’s been crowing about how they were doomed to fail because of x86 as a CISC design. Intel killed off most RISC competitors as Moore’s Law held in the 90 and they could just add more transistors to turn x86 into a facade. But that increase in transistors and doing whatever possible to keep x86 performant meant they were doomed to lose the power/performance war that came with mobile processors. ARM held on just long enough in the low margin embedded world to then conquer mobile. Intel was able to win price/performance through superior fabrication and economies of scale, but power/performance really does require a superior design.

If Intel recovers, it may need to jettison x86, or offload x86 interpretation to a secondary unit for desktop processor with it gone from server procs.

This would make me happy because it’s been crushing to think I might go my entire career/lifetime with little endian processors being the mainstream. :-/

>...created by Capitalism away from the wealthy and into the scapegoating of immigrants.

Which is of course why Big Capital is against this ramped up enforcement. To attempt to steel-man your argument for a sec you seem to believe that, because you think this administration is racist, what they're doing is nothing more than a scapegoating of immigrants based on tensions created by global capital movement - they're just taking advantage of existing problems in the economy to push their preferred policy in another different-but-related domain. The larger picture is that Big Capital and the Social Justice inclined left are actually on the same page but don't know it: they both want more immigration, and a depleted or hamstrung level of state sovereignty (the latter leads to the former) and are in a sort of blind-truce right now.

It's not at all clear how mass immigration suddenly stops undermining the existing working class if we just have "more protections" for workers. You clearly understand that the laws of supply and demand are real and brutal. We can do everything you want - increased protections, unionization etc etc - and that will just increase the lumens on the lamp drawing everyone in. A large positive supply shock for cheap, low skilled labor is bad no matter how "worker friendly" your government is - unless of course you want it to go full USSR, where everyone is poor and miserable but they have a job they can count on.
