This study has lots of problems. I'm not totally convinced the results are statistically significant. The problem with using non-linear models and not showing P values is it is open to interpretation what a statistically significant result is. To me, these results don't seem that compelling. For the cholesterol question, the Adjusted Risk for CVD at the 95% confidence level is between 1.39% and 5.09%, and for All-Cause Mortality, it is 2.51%-6.36%. That means according to this study cholesterol consumption is more highly correlated with all-cause mortality than it is with CVD. That seems hard to believe, but might be true.

The biggest issue I have is with using non-linear models. I don't have access to the full article so I don't know why they chose the statistical methods they did, but I'm suspicious that they don't report P values for what it seems should be linear relationships. I don't buy the non-linearity argument in the summary. Once you get into non-linear regression models the risk of overfitting gets worse. There is a lot of work that has to be done to show you've accounted for this, and it's hard to tell from the summary if that was done.

They also didn't control for some things I would have liked to see. Namely, calories and weight gain. So, it could be that all this study is really showing is a relationship between overeating, weight gain, and CVD and all-cause mortality. It may simply be that people who eat more calories and end up being overweight are also more likely to eat a lot of eggs and cholesterol. In this case, it's gaining weight that causes health issues, not the eggs. It's just the case that people who eat too much and are overweight also happen to eat a lot of eggs. What I'd like to see is a study where they control for calories consumed, weight gain, lean mass etc. and then see how a diet with more cholesterol performed against a diet with less cholesterol.
> And if not, there's still enough information from a typical bad hash table (95% of hash tables are bad) to get at the seed via ordering and timing.

Really? How’s that? The SipHash seed isn’t supposed to be recoverable from hashes – that would be a pretty significant break – and I don’t see what other route the hash table would have to the seed.

> Every language has enough ropes to hang yourself and print the value from some known offset.

You mean explicitly reading the seed out for an attacker? If we’re modifying the program to help, I figure while (true) {} is probably a simpler DoS.
Ask HN: What's the tech scene like in New Zealand?
Is NZ a good place to be a software developer, all things considered? I'm curious to hear more about the tech working culture, meetup scene, any interesting startups, and popular tech choices for NZ companies and the like. I'm looking to relocate from London, UK.

The "big" tech companies seem to be TradeMe and Xero, and maybe WETA Labs. Start up wise, I've heard of Rocket Labs but not sure if they count as a start up anymore. Salaries seem to be about half what they are in London, and my impression is that most of the backend dev jobs seem to be .NET or Java focussed.

The author seems to be unaware that there are cheap stepper motor controllers available that handle all the tricky details of moving an axis to a given position smoothly. And they are implemented in hardware, so you don't have to sacrifice any CPU cycles to this task.
Yup.

Similarly, with postal balloting (vote by mail), your ballot is batched (upon receipt), so will be mixed with ballots from other precincts, therefore more easily tied back to its voter.
Few of questions

1. People always make weekend grocery trips. Why can't they just add a packet of coffee powder? Why do they have to use you?
2. Amazon just discontinued their dash buttons. There should be a strong reason for it. Do you know what it is? How are you planning to avoid it?
3. The issue with diapers and toilet papers is huge. They take up a lot of volume and have very little weight. Does the scale approach work for them? I'm not sure.

It'd be interesting to see how you guys evolve going forward. Best of luck :)

Unlikely. Because if we don't come up with an alternative strategy, there is insufficient incentive for the strong to refrain from using the things I just listed against the weaker groups---or the weaker groups to use them first, preemptively, on the assumption the strong cannot be trusted.

We go that road, and in a thousand years, we won't be doing much of anything because we'll be an extinct species.

>I definitely don't want to mess them up too much

You‘re actively trying to get other people to boycott them, which would eventually put them out of business. It‘s the first time I’ve heard about them and I don‘t care one way or the other but be honest. There‘s no „openness to believing“ the „potentially complicit“ here, your post is a complete contradiction.
I’d worry about talent pool being too small (Estonia has a population of only over a million people). It might not be easy to get people from outside to relocate there, as no one else in EU (expect apparently some Finnish people) speaks Estonian, the weather is grim and wages aren’t that enticing. That’s probably why the government is trying very hard to attract foreign startup investors, as otherwise Tallin is at a disadvantage vs say Warsaw.
I mean that if resources were reallocated by a market, literally EVERYONE would be better off. The current situation is not Pareto-optimal.

To put it another way: if the users being asked to conserve water could just pay farmers to use their water, both would come out ahead. The farmers would get more value than from using it for farming, and the other consumers would get more water for a lower price than from alternatives.

In any case, it's bizarre you cringe at the word "markets". Societies that try to avoid markets are horror shows. Markets are an utterly essential social technology for the modern world.
Very interesting read!

Bottomless seems like a clever solution to a common problem. I don’t like subscribing to auto-refills based on dates as I end up with more than I need and causes the reverse of the problem I was trying to solve.

It's better to rent a datacenter then to build one for companies that reach a certain threshold. At certain amount of loads AWS becomes to limited and expensive. Certainly not true for the typical AWS sites or companies.

Even Amazon uses their own separate, dedicated systems for a lot of stuff - not public AWS I heard.
A system to avoid fakes and etc seems like something Amazon should be doing. Not sure if this actually protects everyone or just a few...

"Say we have ..."
Ah. Ya, that'd be neat. Thanks.
What I don't understand is why there is the monthly shipping subscription. As someone who has free coffee at work and only drinks coffee at home on the weekend it doesn't seem like it would be worth paying monthly shipping. I would much prefer to be able to choose between the monthly cost and a per bag cost.
I just don't understand the comparison.

Classical music isn't "popular" just like classic literature. Pride and Prejudice won't be on the NYT Best Sellers anymore than a new Beethoven Piano Sonata recording would top the Billboard Top40.
> Only pregnant cows produce milk.

I think there's a definition confusion here. "Pregnant" means fertilised but had not yet given birth. After an animal gives birth, they are no longer pregnant. If an animal only produced milk when it's pregnant, then it would never have it at the right time for it's offspring.

I think you had meant to say "... if it has been pregnant recently". That's why there are so many confused replies to your comment.
Speaking of bro-science, added sugar is chemically equal to naturally occurring sugars and you can't discriminate against one with out the other (either it's healthy or it is not). Hint: It's not. That fruit may have vitamins, but they are basically embedded in a candy bar nutrition wise. Actually, it's worse than a candy bar because it lacks protein and fat which keep you satiated.

I recently watched the documentary "Cooked" on Netflix. In it, Michael Pollan makes some interesting observations about "real food" vs "industrial food", and the benefits of long cooking times, sourdough bread vs. yeast bread and so on. It echoes many of the same observations as this article.

That's not to say that he's 100% right about everything, but I think there is a very good point to be made that we ought to eat more home-cooked food, instead of fast food and processed food products optimized for production costs and shelf life.

The shift away from each institution having a full-time glassblower doesn't mean that there isn't a lot of science being done in hand-blown glass. There are still lots of companies that can produce fancy glassware, and the Chinese glass industry has flourished. For 99% of science, off-the-shelf stuff is totally adequate.

However, the capacity for repairing and modifying glassware is going away. It used to be the case that your average chemist could go walk down the hall and talk to a glassblower about designing crazy custom apparatus - not so much anymore. Even when an institution does have a glassblower, they tend to be nearing retirement age, and hiring someone who has the broad talent required is very hard...
100% this. They don't control for lean mass or anything like that, so it's hard to say if it's the cholesterol or simply overeating that is the problem. I want to see a study where Calories and Macros are held the same but one group eats more cholesterol than the other and see what those results look like. Sadly those kinds of studies are very hard to do in the nutritional space.

In this case perfect is the enemy of good. The calorie is not perfect but I don't think there is a perfect measure. Is it good enough for a diet? Yep.

How is the proposed system different from computing the cost per gallon by taking the flat rate and dividing it by the typical usage, and using that amount under a conventional billing model?

Either way, it has the same basic properties of "cost is flat over time if you continue to conserve" and "you'll pay more than your neighbours if you use more than them."

You guys are out here giving very strong dismissals of a very good service, and then referring us to a resource you wont even bother to link? Maybe you can link the actual resources to prove your argument instead of assuming you are correct and dismissing people to figure it out on their own. Usually, the standard for conversations here is held to a higher, non-twitter level, and I for one enjoy conversations held to higher standards.

It's because games can be cheaper in countries where the economy is weaker. $60 in USA is a standard price, but that's outrageous in Thailand, and here Epic might charge the equivalent of $30. They do not want people shopping around for the cheapest country to purchase games from.

Walter Bright will probably show up in a minute and tell you D is a better C. He's probably right too. But being the best isn't why people pick C these days.

On second thought, I'm not sure they're opposing alternatives. "How will this look in court" is a combination of incentives and judgement. It seems hard to simplify.

A previous employer of mine had a Glassdoor "problem" with bad reviews. Now when people leave they are bribed with a week's pay to promise not to post anything bad, and their Glassdoor reviews now are packed with glowing praise that look quite fake and contrived.

Things practical things that have helped me:

- The idea of different types of comment. Suggestions vs questions vs more serious, “I think this might break X”

- As a submitter, take the time to do screenshots if it is UI focused. Read through it once and if some bits require explanation then add your own comments. Basically due diligence

- Be hyper aware of how language can escalate a situation. Ditch abrasive sentences. Re-write to be more questioning or helpful.

- if it’s a naming problem, make suggestions. “I find the name X confusing because Y. How about something along the lines of A or B”

- If it’s a larger problem, and you can meet face to face. Then do so. It will save a lot of back and forth. Or make a phone call. You’re there to make the cosebase better for everyone. Not a public flame war.

- Agree as a team etiquette. Ideally codify it

- Ask yourself the question: “Does this really matter?” Sometimes I don’t bother commenting because while I disagree, I realize that it’s a style thing and it doesn’t affect the codebase at large. Sometimes it’s also worth commenting anyway. That way there is a potential to steer things “your way” but no big deal if not.

- Make positive comments. Try not to dish out praise. If you see something cool, a neat trick or a really elegant solution or even something you didn’t know, then it’s worth writing

- It’s okay not to comment at all. If you can’t find fault. Then just green light. Too many people feel they have to find “something”

- I find it useful to acknowledge when comments have been addressed. This can simply be “Done”.

- The offer to pair on a solution to a problem can be effective

You should be close to your customers. My cofounders and I coded most of the MVP in the bay because we all happened to be living there, but then we started going to tradeshows and saw that most of our customers were in NYC so we moved east.

If you are doing a startup where you are a B2B tech company that sells to other tech companies, the bay area is great.
A facial recognition pipeline contains a few steps, for feature extraction people DO resize image to something like 128x128, but for face detection (which is what this repo does) you DON'T.

Also, the reason why we scale down the input image is not for cache effectiveness, it's simply for reducing computations needed. Maybe except for naive matrix multiplication and convolution implementations, which is what this repo does. But there is no point to discuss performance if you are using a naive implementation which by design ignores cache/instruction latency/anything Computer Architecture related. Please, at least take QNNPACK as baseline.
It tripped the overheated discussion detector, which we've just turned off.
I think the point is that tax isn't driving an exodus of businesses/entrepreneurs as OP suggested. The opposite is true and it's driving out lower income people.

Hey all,

Always sad to see good products shutting down. Also a bit frightening as I'm about to enter this same market, hehe.

I want to mention what we're building in case anyone looks for alternatives in this thread.

It's called GitSpeak and it's a project management tool which prioritizes developers first. Our goal is to create a PM tool that devs actually enjoy working with, and which saves them time rather than eat time.

Some of our features include multi-repo views, boards, a rich text editor and a neat screencasting option for code reviews, docs, and onboarding. Plus, we are going to be the fastest one out there (we're using Imba.io to build the tool btw).
