The New U.S.-China Rivalry: A Technology Race
My wife and I always hate reading recipes online. We finally spent like $50 and bought three of the most amazing cookbooks. Salt, Fat, Acid, Heat, which explains how cooking works, Food Lab, and America’s Test Kitchen.

I made a baked potato with a perfect inside and perfect crisp skin from the books, it involved like 4 steps of how to cook, like bathing them in a specific mixture of salt water, baking for 45 minutes, then running olive oil on the skins, then baking for another 15 minutes.

If they didn’t explain the why in the book, which I guess is the copyrighted part, and what the results are, I never would have tried that recipe.

A lot of modern society depends on someone not fucking up. DNS could break if the root nameservers stop working for whatever reason. BGP is a major problem if somebody gets a free pass on sending garbage.

Using AC as a clock is not the worst and most of the time extremely reliable.
Nope. There's man-years of effort per day in keeping it reliable; as evidenced by the point that it takes major political meddling over a prolonged period to throw it off, and an article on HN for people to even notice "it has been acting sort of weird, now that you mention it".

"I didn't notice until now" is quite the opposite of happenstance, on par with the PHB mantra "what do we need devops for, anyway, the network seems to be up!" Well it's up because devops is keeping it up. Likewise, the grid doesn't just magically self-balance around 50 Hz.

Quick suggestion: Include a line describing what the website does on the main page, users can go to the about page and figure it out but it would be better to have a quick intro of what the site is all about as soon as they visit it. You can probably remove it once the website is more well known but the title isn't self explanatory, so an intro would help.

Hemp-lime aggregate is good insulation, but cement-fiber aggregates do not have the characteristic properties of more famous composite materials. Additionally, Portland cement is highly basic and tends to weaken wood, so the hemp is not really acting as a reinforcement in this case, but a filler which reduces density. Hempseed shells (the indigestible portion of hempseed) are often preferred here. See:

Ask HN: API for hiring software contractors?
Are there any platforms that provide an API to hire software contractors?
AC grid frequency is much more stable than any crystal oscillator. After any number of years, AC will, on average, drift 0 seconds from UTC. It's being sync'd using atomic clocks to keep it as perfect as possible precisely because people use it as clock.
Being part of an IoT botnet seems to be all the rage nowadays.
The short version of the story is that grid electricity in Europe is produced by rotating the turbines 50 times a second and that's where the 50Hz AC electricity comes from.

Apparently to match the demand at given instance electricity plants rotate their turbines a bit faster or a bit slower instead of switching a complete plant on and off[edit: this is not exactly right, see the reply below], which results in slight deviations from the 50Hz standard but it is fine as long as it stays between the limits.

At the end of the day, as the demand increases and decreases, the average frequency would be 50Hz and engineers took advantage of that fact to create clocks that may not be accurate to the second but accurate on average. How do they do that? They count the change in the electricity and assume that 50 changes are exactly 1 second.

Unfortunately, due to political issues in the Balkans, the grid was undersupplied or oversupplied for a prolonged period and this created a deviation from the average of 50Hz and the clocks that depend on this average to be 50Hz also lost accuracy that currently amounts to 6 minutes.
I know! Though strangely, my own kitchen appliances didn't participate in the continental time-shift (my microwave oven is still ticking correctly).

And my remark was more: even NTP can't save ou if you shift the time too much, so it's a good thing it's only ~6 minutes so far.
If we go by his numbers and assume the EU uses exactly 50Hz, then +1 minute over a week (7 * 24 * 60 min = 10,080 min) would mean that the frequency in the UK is roughly 10081/10080 * 50 ~ 50.005Hz.

I'm not sure if that is the case.
Most of the clocks do not have a human nearby to push the reset button (if there is one), as they're industrial automation. Alarm clocks and microwave ovens are mostly a side effect here; and yes, if you have adjusted the time manually, you'll need to do that again.
Do doctors not have ways to earn more based on expertise?
It's unethical to study extreme fasting as you have to ask someone to put themselves into a dangerous situation. Someone doing so voluntarily (against advise) and being monitored is fine.
6 minutes isn't a whole lot for a bedside alarm clock. I probably wouldn't correct it unless it reached ten minutes or more, which is when it would start making me late for things.
You'd expect even a fairly good quartz to deviate by more than a minute a year from temperature fluctuations. Relying on AC frequency should allow your clock to operate for many years without gaining or losing time as long as the AC frequency is compensated, which it needs to be or someone is stealing energy.

I disagree. There seems to be so much low hanging fruit to at least reduce the problem but they haven't taken even the smallest steps. This is because they're prioritizing revenue, volume, and selection over fraud prevention.
Wow, I didn't know continental Europe is a single synchronized area. Here in the Nordics (Finland) our grid is separated from the neighbours via DC stations to eliminate the need to synchronize with everyone. Here you can see our grid info: https://www.fingrid.fi/sahkomarkkinat/sahkojarjestelman-tila... - "Sähköverkon aikapoikkeama" is actually the cumulative difference between the 50Hz reference and the actual frequency in the network. When that stays zero, AC clocks keep their time.

edit: I stand corrected, we are in the same frequency domain with Sweden and Norway. I must have confused myself with the DC submarine cables under the Baltic.
Agreed. I forgot to add Celery along with Beetroot and corn.

That's absolutely the same as the statement without assignment from a data flow POV. However, the compiler will likely not optimize it away since it would be too burdensome to proof that strings.Builder.String() does not have any side effects. The Go compiler prides itself with fast compilation speed, so I would not expect it to perform cross-package control/data flow analyses.

We've got a few family recipes. They're mostly not really secret, and at least in our recipe book their sources are referenced if known. But a big part of what makes the end result good is the practice we have in making them.

The real "secret" recipes tend to be for things that build on a public recipe, or are simple enough not to need one. If you asked us how to make it (and we'd be happy to share what we can), we'd only be able to give you the base recipe, or perhaps not even that, but what makes them good is the local tweaks, ingredient selection and experience in cooking that gives consistent (or at least consistently good) results.

BMI is body mass in kg divided by the square of height in meters. The typically cited normal range is 18.5 kg/m^2 to 25 kg/m^2.

Technically, you can use whatever units you want, but almost every chart uses units of kg/m^2, and if the units aren't explicit, they're quite probably using kg/m^2.
Well, no, not if the voltage for example doesn't stay constant nor changes with a constant period, because then P=IV becomes an integral that doesn't simplify like we are used to.

Calcium isn't going to magically go into your distilled water and "remineralize" it - because most minerals aren't air gases. Distilled water pulls minerals from cells and causes apoptosis. Its just simple science of osmosis. Its not a big deal if you arent fasting, because most people get their minerals from solid food anyways.
I found some more information:
http://www.balkaninsight.com/en/article/government-pays-a-mi...

Since the end of the Kosovo war in 1999, the four northern Serb-majority municipalities have not paid Pristina for their energy consumption.

To make up for the shortfall, people from other areas of Kosovo had a percentage added to their bills to pay for the north’s electricity.

In December, the Energy Regulator’s Office announced that electricity bills will be reduced by 3.5 per cent as consumers will no more cover the cost of the four municipalities’ power as they have done for the past 19 years.
> So either it's acidic and has minerals

Carbon dioxide isn't a mineral. When water absorbs CO2 there is an equilibrium reaction where (H2CO3) carbonic acid is produced (the percentage depends on things like the concentration of CO2 and the temperature of the water, among other things).

> But is it still safe to drink?

It's safe to drink, but it's more acidic than normal water (which is slightly alkaline). Not to mention it's missing a bunch of minerals (and things like Fluorine which is a good idea to have) which could negatively impact your health -- there are a lot of minerals your body needs that come from "trivial" sources like tap water or table salt.

> Evidently it's still the closest to ph neutral as water can get, says this source at least.

This doesn't make sense -- if something is acidic you can always add a base (like NaOH) to make it more alkaline (or neutral).

Not to mention that the quoted pH of 5.5 is considered "strongly acidic", as opposed to tap water which is in the 6-8 range that is between "neutral" and "mildly alkaline". Which means that according to their own information, distilled water is not the "closest to pH neutral water can can".

Reference.com isn't a particularly good source either.

Composable infrastructure explained
I'm kind of derailing here, but I strongly disagree about the Blender UX being horrible. After getting used to it, I find it one of the most usable pro tools. The command-based approach is IMO far superior than the usual approach of having tools and a toolbar you must switch. The windowing system is amazing and everything being scriptable is incredibly powerful.

I consider it somewhat similar to vim or CLI programs in general in that regard... It violates all conventions you are used to, but internally it is very consistent and well made.
Even though this is clearly a benchmarking game, I don't like that it does not explain how the things benchmarked against each other sometimes have drastically different usecases.

This is why fasting often results in both kidney and liver damage along with enzyme increases.

Could you point to some reasons why you'd think that there is anything deep and profound about deep learning?
As far as the evidence I know goes, its very shallow as a scientific concept. All there is, is the idea of using convolutions for image feature extraction, which predates "deep learning" by decades. And there is little evidence that the nets do anything more than memorization, which is hardly profound too.

Heaters and similar high-draw industrial automation rely on a clock (which is not necessarily this clock - plus optionally another signal sent by the power provider over AC) to use off-peak (i.e. cheaper) power. Six minutes' running at peak power rates can get expensive at scale.
Grids ensure the cycle count is correct over the day. There will be some drift from spikes and peak loads, but they adjust the frequency to compensate. They have atomic clocks, for the EU grid it's in Switzerland, to track the cycle count.

UK and EU grids have websites letting you look at frequency history.

There's still an awful lot of infrastructure keyed off having an accurate synchronous time, including billing systems, traffic lights, street lights...

When is this stupid myth finally going to die off? Our body is horrible at processing compounds that are not bound organically, so any pure mineral you take up just taxes your internal filtartion. Your body will gladly take minerals and vitamins when it is organically bound (e.g. in a fruit or vegetable). Eat some of those and you'll be fine.

This is not just theoretical, we own a reverse-osmosis filrtation system that produces water that is very clean (around 1 ppm - compared to hundreds in regular tap water, probably even cleaner than distilled water) and I'm an avid water drinker (3-5 l/day) since a few years. I don't eat food suplements either, but try to get some reasonable amount of vegetables in my diet and a salad now and then. I'm feeling fine.. so much for minerals and ions - bah.

Mortgage Application – Tips for Getting Better Credit Rating
Textiles is a funny one, it makes for a great (extreme) example for looking at current and past economic system debates. Free market emergence vs centralized design. Consumerism vs.. whatever the alternative is.

For a central planner in 2018 (if planned economies were still a thing), clothes would be an easy one. It's easy & cheap to make enough clothes for everyone to wear, in above-median economies. You might face inefficiencies. but, there is little chance of failure like the eastern block's automative industry failures in the 70s.

Free markets see efficiency differently, but from a planning perspective, the free market for textiles seems pretty inefficient. The hard inputs are cheap. The biggest "value adds" are not strictly necessary: fashion-design, wholesale, retail and marketing.

I realize this is a cheat, but imagine a small, leninist country popped into existence today. The central planning comittee could go to a global clothing manufacturer and order 1 million winter jumpers. They would buy them at a small fraction of retail prices. Jumper problem solved. You can deal with a lot of inefficiency before the cost of a jumper approaches the average retail cost of free market jumpers.

The variety, choice and such will be gone, but it's unlikely there will be a shortage of jumpers.

I've framed this in a potentially argumentative way, but if we look past the ideological aspects, the fashion industry has a lot more of "avoidable" costs, from a purely utilitarian perspective.

Thinking back, It's interesting to recall the last days of planned economies in eastern europe. There were all sorts of shortages. Most iconic was cars. Most ridiculous was consumables like toilet paper or tires.

With clothes.. One recurring story from eastern european travelers in the late 70s and early 80s was jeans. Jeans represented western youth culture, rock and roll, liberalism.. People wanted them, really wanted them. I've heard several people (famous people and people I know) talk about exchanging pants with someone (presumably someone they like) in the street, and making their day.

I don't think they had pants shortages though. People had pants, they just didn't have cool pants.

Curious.

The practical, measurable, rationally justifiable needs this industry serves represents a tiny fraction of its economic output. Mostly, it's about decoration.
