The importance of Heavy Water for the Nazi weapons-development program is overstated. They could simply have used graphite (carbon) as a moderator, as the early Manhattan project breeder reactors did. However, they had made a measurement error on the neutron-absorption cross-section of Carbon, showing it as too high for use as an efficient moderator, hence they went on a wild-goose chase to separate Heavy Water by electrolysis, for use as a moderator using the Norsk Hydro plants at Norway, which were eventually destroyed by Allied sabotage and bombing. All this rigmarole was therefore due to a small laboratory-methods error by some little-known German scientist (probably contamination of his carbon samples with a trace element like Boron or Cadmium). Graphite was readily available in Axis territory - a few more tests would likely have found a purer source without Boron contamination.
Seized, absolutely not. Of course since the government already has the source there is nothing that needs to be seized. The government can just declare the temporary monopoly that they granted on copying it to be over (to be clear, this would take an act of congress...).

I'd almost be sympathetic to them doing that - but I also think the outcome would be absolutely terrible. Necessary maintenance (fixing security bugs, updating to new hardware, etc) takes a lot of work and I'm not clear that anyone else would step up to do a good job of it.

Foreign language was required for two years in high school. People in Europe seem to forget that I can literally drive for days and not leave my country nor have any use for a language other than English. If I were to become fluent in anything other than Spanish, as a second language, I'd rarely get to speak it unless I sought at some kind of language group.
Doctors shouldn't even have to do it. The treatment center should be able to do it. For example:

Rolled ankle
100% [of patients get charged]: Office visit: $50
58%: X-rays: $55 - $95
22%: boot/cast: $240
3%: surgery: ??
<1%: other: ??

This would't work for all symptoms, but it would work for a lot. But no treatment center does this.
I started using Acronis to backup everything I don't want to lose about a year ago. A couple months ago, one of my hard drives failed (which I've never had happen before). Instead of trying to limp my files from the half-working hard drive, I just restored to the new disks and remapped the hard drive to the old letter, took maybe an hour and it was like nothing had happened.
A problem that's alluded to in the article is that Kodak didn't focus on the high end of digital cameras nor in the sensors and components. So even as an imaging company they didn't understand that focusing on the low margin mass market they would be doomed eventually when cheaper mass market product would come out.

Not for editing. A library can do dynamic change during transcoding or live broadcast, add new inputs/output, change output settings. It is more like a Video Conference backend, but keep FFmpeg's libav* capacity.

I expect there are automated tests, but it's been my experience that automated tests are usually not very deeply implemented. They often test the expected code paths, and new code, with new tests that fail to review the existing tests can often result in regressions that are not caught.

A colleague recently pointed me to fakespot.com, where you paste the URL of a product (like an Amazon product) and (it seems) it does an ML type analysis to score the likelihood of fakeness in the aggregate of reviews with a score and then highlights the likely fake ones and why it thinks what it thinks.

There's surely a market for verification for customers as much as there's one for the criminally-minded sellers.
TXR Lisp is a dialect that has decent features for munging text. It's part of a two-language combination called TXR; the other language is the TXR Pattern Language: a notation for matching small and large scale structures in text documents and streams.

TXR Lisp allows various classic Lisp operations to also be used on vectors and strings (think car, cdr, mapcar* and numerous others). It has array referencing that support Python's negative index convention. Sequence subranges are assignable places, so if s holds "firetruck" then (set [s 1..-1] "lic") changes s to "flick".

TXR Lisp is loaded with useful features, all packed into a small executable accompanied by a small library of Lisp files.

The authors talk about the possibility of replicating the universe rather than simulating it. They conclude that it is not possible to replicate, but I don't think that conclusion has much value. If it were possible to replicate digitally the universe with resources less than those of the entire universe, that would suggest that it is possible for the actual universe to exist in a simpler form. Occam's razor would then suggest that the real universe would simply take that simpler form. So if the universe is as simple as it can be, retaining all its currently observable properties, then it follows that is inherently un-replicable. Or, put another way, the universe is its own replication.

Simulation is another matter. Simulation by its nature cuts corners. Otherwise why bother? The challenge of the game of deciding if our universe is a simulation is finding a way to spot the shortcuts taken in the simulation.

Except in Apple's case, Apple's products last longer and have higher resale value. Apple tightly controlling the supply chain and who repairs their products directly influences the secondary market value for their products.

When you go on eBay to buy a used Macbook, you can be reasonably sure that what you're buying has had "complete repairs" with original parts (if it was repaired at all). Buyers can be sure that the computer they bought didn't just have a pin bent back, but has some other unresolved problem that will lead to a failure later on. That increases demand in the used market and gets better prices for sellers.
No, because of bad passive safety in Ladas.
Amazon kind of audits and reviews products, or at least has an official program for sellers to solicit user reviews: it's called Amazon Vine [0].

For the reviewers (the "Vine Voices"), it looks like this: on a regular basis, you can choose a product to review (based on your past reviews, purchasing history etc., maybe - they don't disclose how that works), and Amazon sends the product to you. Within one month, you have to post a review.

You can post whatever review you want; to become a Vine Voice, you need a reasonably high reviewer ranking (mostly based on "helpful" votes: [1]). The reviews are labelled as written by a Vine Voice.

As a side note, I know a Vine Voice, and they get emails from companies offering to reimburse them for a product in exchange for a five star reviews every few days.

Singapore does this really well. A hospital is mandated by law to provide you financial counselling - it’s like a predictive charge sheet of what you will be charged when you’re admitted to the hospital.

Read The Magic of Thinking Big. You're not a wantrepreneur - you've tried something and been paid for it, and that's a big step that a lot of people don't get to.

Changing your mindset is the first step. Don't think that because you only have five hours a week to work on your project, that it is forever relegated to "side project" status and capped out at $100/month.

It sounds like you want to focus on web apps, many of which are heavily dependent on organic search traffic. The first thing that I'd do after reading the book is to get a SEMRush free trial - a lot of affiliate sites have 30-day free trials. Look at how many people are searching for your target keywords, the keyword difficulty score, what advertisers are bidding for the keywords, and traffic of comparable sites.

If everything checks out, look at how you can improve on the comparable sites. Everything has potential for improvement - even if your tool works exactly the same way as a competitor, just optimizing the website copy (do a ton of A/B tests and talk to your users) could yield impressive results.

Hope this helps. Good luck!

> it's probably best for businesses to lease devices from Apple than to deal with all the nonsense around repairs.

Heh. Apple's stance on control and repair starts to make a lot of sense when you think of it as apple's transitioning phase to a device-renting business model. They want to make truly owning and repairing your device as inconvenient (and illegal) as possible so that people are more inclined to pay monthly for access to a device.

I just hope other OEMs aren't capable of following in their footsteps.
Right, but those other products pay Amazon to show them when someone searches the competitor’s brand, so they will keep showing them even if you don’t want to see it.
As the previous maintainer of Reel ( High-performance Web Server based on Celluloid ) alongside the author of Falcon ( Samuel Williams ) I am proud to see this release get some attention, and heartily congratulate the author on work well done, both in the release itself, and in progress within the Ruby language.

Samuel is one of Ruby's best. He wrote RubyDNS as well, which was one of the best implementations of Celluloid, the asynchrony / concurrency / parallelism / distributed computing library written in Ruby, which has since come to EOL or hit a ceiling as trends shifted.

I am happy to see Samuel ( ioquatix ) continue his momentum personally, and contribute so much.

> The discussion continued to talk about tort law, and how he's unable to even get a person to sue. He can't sue Yelp, because Yelp wasn't the author of those posts.

Yelp doesn't need to be a party to the lawsuit for a subpoena to be issued to them. You sue the poster as John Doe, send a subpoena to Yelp for the poster's account information and IP address, send a subpoena to the poster's ISP for the account information of the user assigned that IP address at that time, and keep following that trail. Eventually you might find some person who was paid to post the fake reviews, and you can use the legal system to find out who paid them. (In fact, they'll probably cooperate with your investigation in exchange for dropping them as a party.) There's no guarantee of success -- you might find the trail ends up with a no-logging VPN, an open Wi-Fi hotspot, or some other multi-user shared environment where the activity can't be linked to a specific person -- but it is possible to try.

In fact he was outright pro-Universal Healthcare, eg: "Where, as in the case of sickness and accident, neither the desire to avoid such calamities nor the efforts to overcome their consequences are as a rule weakened by the provision of assistance, where, in short, we deal with genuinely insurable risks, the case for the state helping to organise a comprehensive system of social insurance is very strong.

That's from the project owner's point of view but what about from the starrer's perspective?

I think most users use stars to denote endorsement/interest in a project. If you move my endorsement from projectA to projectB just because they merged, that assumes my endorsement/interest still applies.

That feels like a significant assumption that may not hold.

I've seen an assertion that brain surgeons have seven times the risk of developing Alzheimer's as other surgeons (although I can't seem to find it now). If true, that would support an infection hypothesis, though not necessarily implicating HSV.

Valacyclovir is cheap and safe enough that it could be given "on spec", to a very large number of people at risk. If it works, it works.

One might interpret the delay in acting on the infectious hypothesis here as a result of the overwhelming majority of Alzheimer's researchers having no experience with virology. What should you do when you discover you have spent your career on something that turns out to have nothing to do with the cause of the disease you have studied? Probably not try to become a virologist. The most nimble must be casting about for other topics in brain microanatomy and gene expression.

In ten years we might see a flowering of other results as they turn their attention away from Alzheimer's to topics that had been neglected.
I'd say that's an additional way to describe it.
Hey Tom! When I think of GitHub, I think of Rails. If you were building a new SaaS product today, would you still use server-generated HTML (w/ js sprinkles, as DHH likes to say), or would you lean toward heavier clientside javascript?
I got a bike light on ebay and after a few months the battery failed. Even though legally I have 1 year warranty I just can't be bothered arguing with a seller for days and then having to pay return shipping which is almost as much as the light is. I ended up getting a light at the store. Cost me a little bit more but the quality is soooo much better and the battery can be replaced rather than having a sealed plastic casing.

If I ever have a problem with this light its only a 3 minute ride back to the store to return it and I know they won't try and dispute it.
It makes sense. Continuing in Tesla's footsteps was doomed to failure. You end up wasting 90% or more energy being transmitted. And it significantly raises noise floor for 'power'. This just seems like a bad ideal all around, so no surprise they're "pivoting".

A way this could have worked, is if it could tell where the charging devices were, and then beam-form in that direction. Then you'd be limited to by how many beams you could initiate.
Your link is not relevant. The Canonical dispute was about another website using their name and logo as descriptive materials associated with reportage/complaint. It was not about the selling of goods bearing that trademark.

Selling non-genuine products bearing another company's trademark is not legal. Failure of the trademark owner to police such activity can dilute the strength and future defensibility of the trademark.

That isn't the same issue as microbeads though, because those hit our tributary rivers and lakes where ecosystems are less resilient.

That's not how Yelp works, though. It's not opt-in or even opt-out. I'd guess most businesses reviewed on Yelp have no relationship with Yelp.

And ones with primarily bad reviews (which may not be their fault: cheap motels in particular seem to attract bad reviews from people who expect too much for the price) could just refuse to acknowledge any reviews.

Plus I think users are attracted to the illusion that the business doesn't know who they are. People would be less inclined to post reviews if they knew they'd be emailed directly to the business owner for sign off.

"Correction: Sept. 13, 2018

The initial version of this article overstated the rate at which neurosurgeons and spouses of Alzheimer's patients develop the dementia. The risk is nearly 2 1/2 times greater for neurosurgeons, not sevenfold, and 1.6 times higher for spouses, not six times greater. On Sept. 18, the article was changed to say that the risk for neurosurgeons was a comparison with the general population, not other causes of death for the doctors."
