There's a 1700km track network with both automated and non automated trains, so slightly larger than disneyworld.

I understood "caveat imperator" to mean operator (commander) beware

It's currently very difficult to move equipment and expertise from where it is to where you need it for the project. So far the biggest problem for us has been getting panels and inverters from China to site, but it's now shifting to being more of an issue around continuing operations here as the virus escalates. It's highly likely this will delay solar and wind projects in the construction and planning phases.

The other interesting angle is what will happen to electricity emissions as demand drops, it should increase the market share of renewables as the highest cost generators drop out first.

The second source you link to states 60% of that energy is in manufacturing, and 40% in use. Wouldn't that imply using a hosted solution only when you need it would be more environmentally friendly than buying your own gaming PC?

They weren't at 801mph airspeed. The article didn't make it clear exactly, but:

"The Boeing 747-436 reached speeds of 825 mph (1,327 km/h) as it rode a jet stream accelerated by Storm Ciara."

Ie max ground speed 1327km/h. And:

"The jet stream reached speeds of 260 mph (418 km/h) on Sunday morning, according to BBC Weather."

So if their max ground speed coincides with max wind speed and the wind was perfectly tail, their air speed would have been closer to 909km/hour.

Seems like it's possible: https://www.bloomberg.com/news/articles/2019-12-05/apple-buy...

Chain drive can be up to 98.6% efficient, you'd have a hard time beating that.

Yes, and Amazon started selling books in 1995. Ie when it was still a cushy market.

And they're going to do it in three weeks. Amazing!

"Spy agencies and police have said that the Christmas and New Year period poses a heightened risk of terrorist attacks."

It'd be comical if there weren't serious risks of them damaging internet security in the process.

In effect it does. If you have read 20 pages and found no typos you estimate the chance of an unknown page having a typo is 1 in 20/3. But if there is 0 unread pages then there 0 cases to apply the probability to. Make it 100 pages, then you have 100 cases each with a 1 in 20/3 probability. Of course if you read 30 more and still don't find a typo, it's now 50 remaining cases each with a 1 in 50/3 (estimated) probability.

Healthcare? You could plausibly have great quality of life for healthy people, but once you get sick you lose access to it. If you're dead, you probably don't notice the quality of life living people have.

According to trip advisor they're not in the top 10.

So if BBQ is your criteria, consider Tennessee?

From the article:

"But quartz oscillators have some problems. They don’t keep time as well at high (and low) temperatures, and they’re a relatively large component—1×3 mm or so. In their quest for smaller and smaller hardware, Apple has recently started using MEMS timing oscillators from a specialized company called SiTime to replace quartz components.

Specifically, they’re using the SiT512, 'the world’s smallest, lowest power 32 kHz oscillator.' "

So it was size, not cost that led Apple to be using a susceptible component.

This snippet is amazing:

"Theranos kept up the illusion that they were running a lot of the tests from finger-stick blood draws by hacking the Siemens machines to work with small samples"

No wonder they had so many inaccurate test results.

I disagree that short term returns make it an investment. Speculation is term that much better fits the action of buying a currency with intent to return a profit.

"A speculator is a person who trades derivatives, commodities, bonds, equities or currencies with a higher than average risk in return for a higher-than-average profit potential" https://www.investopedia.com/terms/s/speculator.asp

This was my thoughts too. The values appear to be fairly similar for all three, especially given the large variations.

Not to mention that they're explicitly trialling this with people "for whom celiac disease had been excluded". So an alternate conclusion could be "people without celiac disease but with self reported gut issues don't respond significantly differently to fructan, gluten, and placebo". Which is... not surprising?

The $2.5B is ~$60 per connection (40 million households). Only households of "poor citizens" don't have to pay a fee, so if the cost is more than $60 per connection you can charge the non poor households to cover the difference.

They actually mention the hanger collapse during the video, that was the only ex-operational Buran that got crushed. The hanger in the video is the one that houses partially completed Burans.

A raspberry pi with external HDD running is about 5W. That's 130 kWh less than a FX160 over an always on year, or $27 at average Australian energy prices.

Sure these servers might be handy for some things, but the Pi still has a lot of advantages. For me it's small form factor, low power consumption and GPIO.

Your 'standard' bottled water bottle is more like 15 grams[1], so to use that metric we're talking 6 to 35 bottles per square kilometre.

Personally I'm more concerned about these plastics getting into my food than I am about whether they'll support my chair. We're going to have serious ecological issues long before these garbage patches become visible - or floatable.

Perhaps the economics are buy really cheap bikes and hope on average they are ridden for enough hours to cover the cost before they end up broken / lost / stolen.

They're also deliberately heavy to make them harder and less attractive to steal. Not an issue in a flat city, but much less fun on hills.

Hopefully in the long run electric assist is practical to implement on these bikes which should ameliorate their weight.

I've had the same experience in Poland. Tried to tip a driver who'd gone above and beyond in helping me out, and the driver refused to accept the tip.

The whole thing seems to illustrate just how far out of whack tipping expectations are in the US compared to the rest of the world.

This is partially mitigated by double use of the island's connectors as interconnects. If energy production on the island dropped to zero, the entire cable capacity would be able to move power between connected nations. The 'flat' United Kingdom has 2.8GW of existing pumped storage capacity. (http://www.british-hydro.org/hydro_in_the_uk)

If this was the only power generation in the area it would be an issue, but even such a large power plant as what they propose would be a highly effective addition to the grid of the north sea area.

I was waiting for the "It's like mechanical turk, but for x" moment, but it didn't come. Perhaps a gamification twist given the name? Nope, apparently same same but more flexible for the workforce.

I don't think you're accounting for interest in that calculation. If they have borrowed 60% of GDP at an interest rate of 3%, it would take a 1.8% annual increase in GDP just to match the interest on the loan.

That is also ignoring the fact that you can't just take the entire GDP growth and use it to pay the loan, you have to collect fares and taxes which can only be a proportion of that growth. If you collect more in fares than the increase in GDP, you're leaving the country poorer than they would be without the railway.

Djibouti is going to need to see some pretty big additional growth from the railway to make the project worthwhile. Not to say they won't, be it's easy to underestimate just how big of a debt burden it is for a small country.

Have you read the details of SpaceX's planned internet offering? Existing satellite based internet services have high latency. This is exactly the problem their solution aims to solve.

If it's based on the one suicide and extrapolating to a death rate of 0.3%, I'd call it a bit of a stretch. Yes that would make it the leading cause of death if it did continue, but given the tiny sample size and single occurence (which may or may not be related), I don't think you can draw any conclusion.

Given that uncertainty concluding the study to work on the drug before trialling it again makes a lot of sense.

I suspect the reason is that it is just straight up expensive to ship to Australia from most places. We're actually quite a long way way. Adding to this is that most only retailers aren't shipping enough overseas to negotiate bulk rates like they can for domestic shipping.

The exception is businesses that do ship a large amount to Australia. Examples of this are online book and bicycle retailers in the UK and Amazon themsleves in the US. Their lower shipping prices are likely a combination of subsidisation and bulk discounts.

If you want confirmation Death Wish isn't trying to rip you off, compare against the USPS pricing calculator for a similar package. You can also check against what a freight forwarder (who do get bulk discounts) charge, and you'll see it's not much less. I recently got a similar package shipped to me and I remember paying pretty much bang on $27.

The United States was a country last time I checked, unless Mexico and Canada have mysteriously disappeared. A country roughly the same size as Australia, which has a significantly smaller population.

The Australian government came up with a credible plan to provide high speed internet along the lines of the Swedish model being described. It has subsequently been modified to be less fast, but the concept of providing government-owned infrastructure to be leased by multiple providers on a competitive basis stays.

If it's possible in Australia, it's definitely technically feasible in the US too.
