> To each their own. Durrett's text is perfectly fine. The books you mention are older, and perhaps you originally learned from them, so you still hold a torch?

Durrett seems on most of the topics to have less than any of the four texts I mentioned.

> In particular, sending people to Loeve for their first course in measure theoretic probability would be really cruel.

I listed the authors in reverse order in which to read them! The easiest start is the last, Breiman. But some things in Loeve are good, e.g., sufficient statistics. Neveu is my favorite as the most elegant, but his exercises are the most difficult. Breiman and Chung are fine. IIRC, both Breiman and Neveu were Loeve students.

> Personally, I learned from Feller, and Billingsley, and finally Durrett.

I used Feller I and/or II for reference. Otherwise his writing seemed to lack an overall unification.

The only Billingsley text I used, and then only for a small topic, was Convergence of Probability Measures.
"For a gene controlling alcoholism, it would have to appear somewhere where alcoholism had some substantial impact on survivability"

No, it doesn't. It needs to be a gene that has an impact on alcoholism, but the thing being selected for could be something else entirely. Consider sickle-cell anemia. If you just look at it as the "sickle-cell anemia gene" you'll boggle at how it spread as far as it did, but that's because it's also the "malaria-resistance gene". If alcohol is introduced into a population that did not have widespread, ready access to it for long time frames, there's no guessing in advance what could happen as it interacts with arbitrary other adaptations that have never "seen" alcohol before.

I want to point out you keep boggling at how intrinsically impossible this all is, and I keep citing concrete examples of very similar things that happen. And I'll reiterate that my point is that it was a viable theory, until the facts contradicted it, not that it was certainly correct and certainly not that it's correct now. Simply that it was not a stupid theory. (Indeed, given that this is just one study I'd be glib even saying it's "disproved", it's merely one that we must Bayesian-update to a much smaller probability. But I wouldn't downgrade it to zero quite yet. We've got a lot of gene science left to learn. And as always happens, when we take a closer look, it always turns out to be more complicated than we thought...)
Well, somebody has to detect the failures, and restart failed processes, etc. so you can just "go with the flow". If you can "just crash" that's great, but it doesn't lead to much helpful advice for people who actually design the underlying systems.
Among experienced teams, most failures aren't caused by single-node/single-service errors. They've already designed & tested for that case, and the ability to handle them is baked into the architecture.

The interesting failures are caused by a cascade of errors - someone writes an innocent bug, which causes a single-node fault, which exercises some pathway in the fault recovery code that has unintended side-effects, which results in an unexpected condition elsewhere in the system.
> Additionally, I'm a tad confused about this concept of Democracy (warning, not really confused, just arguing): If the president is elected in a presidential election and represents the majority of the people, why then do we elect a separate set (branch, as they call it), of individuals at a more granular level that could very well "fight" the already-elected president?

You're confused. That's not a bug, it's a feature. The whole political philosophy of the US is that no one person gets power that somebody else can't block.

> Could the entire problem not be solved by removing the entire "checks-and-balances" concept, and simply hold presidents accountable for their actions (or lack thereof when it comes to promises)?

The thing you see as a problem could be solved that way, yes. But imagine that the next president is Trump rather than Sanders. Still think it's a good idea?

The public makes bad decisions at the ballot box sometimes. No matter which way you lean politically, you're sure to be able to find examples in the last 20 years. Having Congress able to block some of their most stupid ideas is genius, rather than a flaw.
Curious AI Wants to Make the Singularity a Reality
Some lessons learned for me.

1. Each service is an island, treat it as such.

2. Each service gets its own source repository.

3. Each service does 1 thing nothing more. That one thing might be 4 different pieces.

4. Tests are unit tests per service, and you should have 100% coverage. We are primarily node.js and use mocha for our tests.

5. Services never talk directly to each other. A message queue or bus architecture should keep services from talking to each other. Yes this adds complexity but it prevents laziness from causing fragility in the system.

6. Have integration test that test functional requirements that span multiple services. This lets you confirm that version updates of one or two services hasn't broken anything.

If you have specific questions let me know. We screwed up a bunch but I think found a good path now.

> If a teacher is bad, it is the principal's responsibility to notice and deal with it.

Isn't this the case pretty much everywhere? In reality, if a teacher is bad, there is precious little the principal can do about it in Finland. Almost all teachers are fortunately good, but I have met a couple who were completely hopeless. The schools absolutely couldn't get rid of them once they had been hired to permanent positions.

Personal experience (Finland): my grade 3-6 teacher was himself the principal in a two-teacher school, an electrician by profession, and had been quick-trained to take a teacher's job after being discharged from the army at the end of the War - no master's degree, no degree from any university. He actually did close-order drill for PE. And if I was unruly, he hit me in the head.

Yes, teachers are better trained nowadays (what I describe was 1970's and the man retired in 1980's).

While I agree with you, and with the educational system of Finland, that high PISA score is irrelevant, to say "PISA is just one metric" seems to ignore the context that PISA is the basis for nearly all of the international comparisons, and the follow-on discussions and policy decisions.

That is, andyl said Finland 'achieves better educational outcomes'. This is (in my experience) based on PISA. Indeed, much of what I've read coming out of the US is that students must get more 'academic' education, backed by large-scale testing, in order to compete against the countries with high PISA scores.

You use the term 'do not really believe Norwegian results are that much different'. Could you explain the basis for that statement? The thesis is that a (near) monoculture is a reasonable explanation for high PISA scores. The example of Norway was to show there isn't a simple, direct correlation.

I don't think you don't believe the scores aren't difference. Instead, your objection seems instead to be that PISA isn't a stable/useful metric in the first place, so that comparisons aren't relevant. I think your suggestion is that there simply isn't data one way or the other on how homogeneity affects education.

Which means, I think, that you also disagree with andyl's hypothesis, but for different reasons.

The union members are usually either paid or pressured into "volunteering" for candidates; it can also be a requirement for advancement in the union. If union members were making the decision of whether or not to support political campaigns without union influence, your point would be correct; but that's not what's happening.
Though Tableau is incredibly expensive, I haven't yet found anything better that Tableau for web dashboard and visualization. Tableau is strictly a visualization tool and not statistical analysis tool. Tableau expects you to perform all the calculation on the back-end and send it the final data for visualization. I have also used Shiny, D3, Flot, Highchart, Chartio, Spotfire, Bime, FusionCharts,Qlickview and nothing comes close to Tableau.

Maybe I just had a good person, but when I cancelled my Comcast, I just called up, they asked why, I said, "That's not important, just cancel it." and they just did it.

That said, I think this might have been a few weeks after some high-profile example of someone recording them dicking someone around for a while, so maybe they had been told to dial it back.
Statistically, yes. However, there is rarely a week that goes by without some incident of kidnapping & murder.

What you suggest is a start and can certainly be helpful in uncovering some failure modes of the application, but it is by no means complete answer. Debugging can be hard but at least it is tractable - you start with the effect and slowly work your way towards the cause. But anticipating which of the changes in environment (including but not limited to: sudden spikes in traffic, changes in statistical distribution of data, subtle partial hardware failures, peculiarities of the systems software etc.) will result in failures is impossible. What is the worst is that all causes can be relatively benign when taken in isolation but when they are all present they interact in some devilish way resulting in a total breakdown of your service. This facebook engineering blog post comes to mind as an example: https://code.facebook.com/posts/1499322996995183/solving-the.... So even if you test rigorously you still need to monitor everything and have some smart people on call to look into the issue when some obscure metric goes haywire.
This is fascinating. We didn't know this existed. Thank you!
I am roughly the same age as you, and experienced the same thing as kid. At age 8 or 9, in the summer, we were outside all day playing with other kids. If I wasn't home when the streetlights went on (signaling darkness), my Mom would come out and whistle loudly, the signal to get home. We roamed for miles on our BMX bikes (no helmets, mind you) and somehow we survived ok.

Now I have a 1 year old son of my own, and I'm truly saddened that he probably will never experience that type of youthful freedom. I am resolved not to become that helicopter parent, but it's hard to battle against the social pressure.

No worries - I appreciate you're probably slammed with many other things to do. I just wanted you to be aware of it.
No, it's not one or another, but they're related. Or should be. I've had to debug systems with dozens of different retry/failure intervals that had to relate to one another in very complex ways for failure detection/response to happen properly. It sucked. Systems where the different layers/modules handle simple retries but give up only according to one set of times and rules are much more robust and pleasant to work with.

Mass alone isn't a significant measure. It's the mass to size ratio[1], which for crows (EQ 4.1) is similar to chimps (EQ 4.2), with higher EQ generally denoting higher intelligence. For comparison, bottle nose dolphins are 5.9 EQ.

> Giving our kids a rich social life and early education without the pressures of a traditional school model is probably the one thing Finnish society has figured out. (The rest is more or less a mess right now.)

Coming from Slovenia, that's what kindergarten is supposed to be. The word literally means "children's garden" and has nothing to do with school.

To quote wikipedia "literally children's garden, is a preschool educational approach traditionally based on playing, singing, practical activities such as drawing, and social interaction as part of the transition from home to school.".

I don't know what happened in the anglophone world that turned this joyful concept into school. My girlfriend grew up in the US and considers "kindergarten" to be the beginning of school school where they start by teaching you how to read&write. Wikipedia seems to confirm this notion.

Maybe it's just semantics and word-meaning drift.
In London it would be moderately unusual - children have to pay for the metro, but buses are free, so they often use buses.

Wealthy children are more likely not to go to their local school, so they might need the metro.

What about the traffic in the toll lanes? Surely the traffic is much better there.

In Southern California, a similar thing happened to CA-91. Immediately after construction, traffic in the toll lanes moved at the speed limit or faster, while traffic in the non-toll lanes appears stopped during the heaviest commute periods.

It seems like requiring an economic solution almost guarantees congestion problems (and is perhaps, arguably, the point -- to extract a toll (ie. easy profit) from a carefully designed scarcity).

Why not try solutions that directly address the causes of the congestion (lots of vehicles trying to move through the same small area at the same time)?
What does "French" mean in this context?
Sorry I wasn't clear. That's exactly the advice. Design systems so that they can crash harmlessly in the small, and availability and scalability come to you quite naturally.

I agree the (distant) second best alternative is to do as you suggest: to try to rely on a paxos implementation that keeps a stable leader and tries to keep track of liveness. That's pretty hard too! Besides all of aphyr's jepsen test series, check this shit out: https://github.com/coreos/fleet/issues/1289 . Tough! Tough even when you think you know what you're doing. And of course no help against freak occurrences where you can't elect a stable leader any more, or you flap leaders, or the election gets stuck.

Currently the only known-good implementation of raft is in Idris. Do you know Idris? I sure as hell don't. Fortunately I know ants. Ants can die in great numbers and still move the leaf. In practice, in production, thousands of terabytes, even on AWS, my ants move and never bother me. Let it crash.

I think that's being overly simplistic. They've had vector clocks from basically the beginning (though I gather they've been superseded now) and have favored the strategy of offloading conflict resolution to the code that's reading the value. Without implementing that conflict resolution, then it might default to last-write-wins, but that's not the same thing as "straight up last-write-wins" since they give you the tools to implement something more intelligent.

> I really wish we could have the ubiquitous "care for others" mentality alongside the "be yourself" mentality

Agreed. I'm not even sure if it's possible for those to coexist, but it's wonderful to imagine - discover yourself and your place in the world while respecting others and recognizing that your actions can negatively affect them. The US has too little of the "care for others" mentality, as evidenced by the large number of individuals who do not believe in climate change and see environmentalism in general as useless government meddling.

I actually do understand that. That doesn't make it a fire sale, though. In particular, a fire sale doesn't just mean "selling at a fast pace". It means selling at a fast pace due to a discounted price. That's where the term fails to match land sales in the UK.
If you post on HN, you should expect a massive amount of traffic. This sounds rough, so don't take it the wrong way, but: if you couldn't anticipate the spike in traffic for your website, how will you handle a spike in (physical) traffic when people suddenly start using your service?
I agree entirely, I also have an issue with "yield on green".

Green means "go" at 99% of the lights I run into. Then there's that one left turn I make that's "yield on green" and I'm not supposed to turn.

I don't think many people are used to yield-on-green lights... so many T-bones its amazing they haven't changed the traffic flow.

The cost of day care over there is stunning. The day care we send our children to in Australia is very similar to what you describe (i.e., compassionate and loving staff, focus on play in a mixed social environment, lots of outings and great food).

But the cost is $85 per day, per child. We have two children so it costs more than our mortgage to take our children to day care. It is also one of the more affordable day cares.

The government is supposed to cover 50% of the cost, but only up to maximum of $7,500. Meaning they end up covering far less than half.
I have Frontier as my ISP at my rural home on the outskirts of Cleveland. The speed isn't amazing (10 Mbps down, good enough for our streaming needs), but is at least fairly consistent and pretty cheap. Service has been pretty decent too, line faults are usually addressed within a day.

But I've heard that experiences with Frontier are a very localized thing and can be pretty dramatically different from place to place. Which at least contrasts to TWC and Comcast, where people pretty universally seem to despise dealing with them.

This county (Medina) is actually crawling with dark fiber infrastructure, with some business and gov't utilization. I'm patiently waiting for a residential service ISP to pop up. As far as I know, there are not any municipal agreements that would block it.
