Good points, I agree that it seems unlikely that Amazon has lost sight of the long term thinking that is largely responsible for making them Amazon.

And it is indeed an arms race, like everything that happens on the internet at scale where money is involved.

But I disagree that the problem is prohibitively hard to solve. In my experience you can always stay just ahead of the black hat players. They're rarely smarter or more talented than competent software engineers and data scientists.

Amazon's failure to stay ahead in this area is, to me, an indication that they're using the wrong strategies, probably because people with the wrong skillsets are being assigned the job of figuring out how to solve the problem.
I live in Lithuania and this season winter here has not yet come (and probably won't now).

Typically winters here have a week or two of temperatures reaching -25c in January, with it averaging around -10c the rest of the season. This winter the coldest it reached was -10c, most of the time it has been around 0c. We haven't even had proper snow that has settled.

Nobody I've spoken to (i.e. grandparents) remembers a winter like this before.

This is one of the problems that I have with most SQL databases: they try to do the magic for you and make it hard to see what's going on under the hood. Databases aren't magic, they are just indexes, and there are only so many ways of organizing them. Providing a bit more transparency into how the data is stored and retrieved allow you to write efficient queries without the guesswork.
Tesseract only does well if the input is clean, aligned, two tone image, already cut down -- but LPR images you get from a moving camera are anything but.

Machine learning is a fine tool for this job. The specific machine learning setup is an overkill, though.
This was one of the early theories about how Facebook would monetize -- that your real-life friends would value their relationship with you too highly to recommend anything but truly great products to you. That hit the reality that people would squander most of their friends for their stupid MLM scheme.
Absolutely. You need some way to prove that the reviewer is acting in good faith. With Amazon reviews, I ignore most of the 5-star reviews and focus on the 2-3 star reviews (1 star reviews are often worthless), mostly because 4-5 star reviews seem to frequently be biased (free item, out outright purchased/fabricated review).

How about compensating reviewers relative to the "helpfulness" of their reviews? Maybe allow manufacturers to refund X product purchases for reviews, but with zero control over who does the review and zero knowledge of which order is being reviewed (can't send golden samples). That's basically how "mystery shopping" works, but that seems to not be a thing with online retail.

There are a lot of good approaches here, but this seems like the only benefit is that it separates the reviewer platform from the retail platform. It's still ripe for abuse unless reviewers have more incentive to be honest than to be bribed.
It's very effective for humidification, the difference is immediately noticeable. The room is probably 100 square feet, I'm only humidifying it at night, so by your calculation it should take only about half a gallon of water which is probably what fits on a towel give or take.

> Kubernetes is the thing everyone will be moving away from in the next 5 years because it was too complicated for their purposes.

Kubernetes solves a huge variety of problems with a single platform. In five years, Kubernetes will still be around, but there will be layers built on top of it that simplify common use-cases.
True. I think the biggest buyer of this would be gov institutions that are constantly looking for building their offensive capabilities (mainly around exploit dev) but find it hard to get new recruits trained up. The alternatives are mostly instructor-led training which is good but combined with this type of platform + remote assistance via chat etc could scale things up.

Most people on HN who are optimizing interest/etc to the penny, and I count myself among this number, have a hobby with similar economic returns to World of Warcraft but poorer graphics. The biggest lever you have available, by orders of magnitude, is optimizing the returns to your career or business. That disclaimer out of the way:

One of the folks who works at M1 Finance pitched me on the following, for folks who have similar cashflow characteristics to the median HNer. (They've essentially productized this, and with slightly more work you could get it out of Interactive Brokers. It's hard to do with most discount brokers due to prevailing margin rates.) It captures most of the advantages of the "hybrid" account and is actually available in the status quo, which is an advantage.

Deposit your paycheck. It is automatically invested. Spend on margin; repay it the next month on payday, when you repeat the cycle. Change this only if you experience long-term unemployment, which you a) probably will not and which b) savings is the least effective financial product to prepare you for it.

Their theory is that the ~3% impact of margin is less than the fundamental return of an equity-heavy portfolio measured in small increments over a long period of time, so you should prefer to be perpetually ~100% invested in your taxable accounts rather than "materially less than totally invested", which is what most well-paid professionals are given usage of a checking account and poor decisions embedded in their financial products. (e.g. If you have $50k net worth, $8k in post-tax payroll per month, and are saving $2k per month, you're no higher than 86% invested and if you are following common financial advice you with a six month buffer in a non-investment emergency fund you are ~24% invested.)

This sounds strikingly plausible to me, for what it is worth, again contingent on one being a well-compensated professional with predictable cashflow in and out and a temperament amenable to discipline and commitment. It is not not not not the consensus of advisors to the American middle class.

Docker is for building a computer program to run on a single computer.

Kubernetes is for building a cluster, often across many computers with many programs.

They work together.
I think brand matters more than ever. It’s anecdotal, but let me give you a few examples of how my purchasing habits have become, and I assume that I used to buy things pretty much like everyone else.

Pants, one of my co-workers recommended a brand of pants from a Danish store called shaping new tomorrow, they have two real stores and their own internet business. They are the only pants I buy now, because they fit my needs. I used to buy pants at various places, but these guys really hit the nail on what I need, and as such their brand is immensely important to my pants buying.

Blood Bowl, I play it and I buy 3rd party miniatures. In the blood bowl community there is a lot of talk on who build the best 3rd party miniatures. I prefer willys miniatures and Greebo Games myself, and typically only buy their stuff. Again these are small mom and pop companies with their own little web shops that have become successful through their brands being associated with high quality.

T-shirts, I used to be a shirt guy. But a couple of years ago I started wearing t-shirts with prints. These are perhaps the best example because you can buy from so many places. And I did, I’ve bought t-shirts from about twenty different shops, but these days I mainly buy from qwertee because their fit suits my body best. Again their brand and the product I associate with it is important.

I used to buy things of amazon, and stores like it here in Denmark. But because it’s almost impossible, or at least takes a lot of time to associate sellers and quality on those platforms I almost never use them now. This was all anecdotal, but if I’m not alone in this, then brand matters quite a bit these days.
I started playing realMyst recently (for the first time). Must admit I found it a bit unfun. Perhaps I just didn’t get into it enough but I found the puzzles sometimes quite unintuitive. I’ve also started The Witness and enjoying it more.

I'm confused, in cases where you have truly no prior knowledge, such as your thought experiment, a bayesian can reasonably select a uniform prior. But often in real world statistical experiments, we have priors we can believe in.
Worth noting here is that Swedish public broadcasting SVT have had an online streaming service since 2006. Even though Sweden is also a pretty regulated socialist democracy in most people's eyes.

Because every time I see one of these headlines on a site full of VC entrepreneurs I take it as an attack on government regulation.

Government should regulate business, there's nothing bad about that. G20 is about to discuss massive government regulation of business to get back lost tax revenue.

It's just important to find a balance.

> All these things are available for Java (MVN/Gradle, JUnit, IDEA, YourKit, etc) but having one right way to do them built in is pretty great.

It's great if you're just starting out, but it's irrelevant in the long run. It can even be harmful when it's coupled with the language, as you get things like having the packaging tool become deprecated, like with go dep, since a 3rd party tool can't compete with a first party tool for adoption, especially in a relatively young language like Go.

For pprof vs VisualVM - I haven't yet done a lot of CPU profiling with them, but for memory I have had the exact opposite experience. VisualVM and Eclipse MAT are much easier to understand and have much more functionality for analyzing the memory of a Java process than pprof offers.

Not sure what (pseudo-)deterministic code formatting has to do with the ease of manipulating program code, but having a built-in AST package is indeed a good idea. Too bad it hasn't been used to write any useful refactoring tools for Go (outside of JetBrains Goland? Haven't tried that yet). I have heard that Google uses go fix recipes to make modifications across their code base, but haven't seen any examples, and I doubt it can realistically be done in a code base that is not ridiculously well tested, and that it didn't require any manual intervention in a few corner cases in Google as well (assuming they did more than a rename).

I'm in the same shoes, and as ridiculous as it sounds but I've been in programming (self-taught) for 10 years now without an especially good knowledge of math. I've been slacking in HS on math classes, despite the fact that I loved math and was really good once I sat to listen, practice and understand the material. Also, I'm painfully aware of the fact that my math is really bad and that I'm missing on utilizing it in my job, so I've decided to practice at least one hour a day on Khan Academy, and eventually enroll to comp-sci university this year.

> I think brand matters more than ever.

I'd go further and say that branding is now often the product itself.

Nike can sell a hat for 20X more than a generic hat when it has their swoosh on it. Perfume is basically a generic chemical wrapped in a huge amount of marketing. Apple makes excellent products, but there's no question that at least part of the premium you pay is not for better quality, but for the brand itself.

While the value of a brand often revolves around vanity and advertising, there are often other factors that are also not directly linked to product quality: such as "fair trade" coffee, buy-one-donate-one shoes, or humanely raised animals for food.

We're moving from a pure "consumer society" into something a bit different (but definitely still consumption based), where consumption is not just for the direct benefit of the consumer, but is also used to signal deeply held values.
I calculated how much it would cost for me to DIY av solar setup, and it was <$10k to completely offset my electrical bill. To get a solar installer to do it, however, was ~2x the cost (best offer from multiple installers). If you're building a new house, it's going to be fairly inexpensive to install solar during the process since you can just include the permits and whatnot in the initial construction.

That being said, I'm against a mandate. Solar panels look ugly, so sometimes it's preferable to have the energy company take care of it. It also requires a decent amount of additional equipment, which means certain types of additional risk.

Instead of this type of legislation, at should just tax carbon and let individuals optimize. If fossil fuels become ~2x more expensive overnight, you can bet we'll transition to green energy much more quickly, but it doesn't push a specific solution. Maybe roof mount solar isn't the best option but some other centralised energy solution is (e.g. nuclear or wind).
It's a good question. As in: If a large enterprise, e.g. a bank or an insurance company, has decided to write an app in Java, they'd choose JEE/TS. That was my original thought.

From my experience in Germany, it's 50/50. There are fake human reviews (Vine Club being a large part of it...), but there are also clearly auto-translated reviews (though they might be posted by humans). It's mostly on low-price items that are FBA'd or shipped directly from China.
