Nuclear designs are like quarterbacks, the best one is always the one "in development". The problems with all of these next-generation designs are not going to be with the physics, but the engineering. These reactors will be operating for 40+ years, and are complex collections of machinery that have wear-out and failure mechanisms that may not be discovered until years after full operation commences - when this machinery is now highly radioactive. Remember the pebble-bed reactor? Sound idea in principle, the Germans found out that its main problem was inherent in the engineering of the fuel - it turned out to produce large amounts of radioactive dust in the reactor.

The description of this reactor, which involves robotic fuel handling equipment operating within the containment constantly moving around fuel elements immersed in molten sodium metal seems doomed to create difficult repair problems as these mechanisms will fail and now need to be replaced/repaired within the hot zone of the reactor. It's quite easy to build a system which technically works, but ends up being uneconomic. To my knowledge there has yet to be a successful long-term operating power generation design of any kind using sodium coolant; the Monju plant in Japan was a failure largely because of problems with the coolant loop (including a leak and serious fire). Until these basic engineering issues are proven to be solved, the fuel physics seem kind of beside the point.
I was living for some time in a city that offered a lot of options for pedestrians but certain things were not available or only with difficulties - e.g. buying furniture - unless you had a car. So living there without a car was fun at first but then it became very draining, especially when having to move from one apartment to the next one.

The logical explanation is probably that with a car one has not only more options but also options are available at lower cost. E.g. one can move to a cheaper area, with cheaper supermarkets but that is only reasonably accessible by car. The irony for me is that cars became that popular in the first place, given that they are a quite unreliable and expensive toy.
Kudos to them then!
AR Quick Look is not Web AR. You cannot write web code (JS, HTML, CSS) to interact with your AR elements within your scene. It's very easy to spot fake Web AR: do they have a link on their website that you can click on and it works on all phone browsers? No? It's some proprietary stuff that is wasting your developers' time.

The current state of AR is
* Hardware is not there yet. Phone-based AR is the current hardware until then.
* Fantastic content is still in the work. Content creators and developers are aware that app download is the biggest slog on distribution. Nobody is going to download (and keep) your app to experience AR for 5 minutes. Most AR experiences last less than 30 seconds.
* True Web AR, where you can literally go to a link on your browser and experience interactive AR, is the best medium for content delivery. Write HTML, CSS, JS and get AR content. This works on both short-form (< 5 minutes) experiences and long-form (>5 minutes) experiences.
* Foundational layers of AR are either missing or vendor lock-in: persistence object (e.g. come back to the same space tomorrow and see the same thing), multiplayer (e.g. see the same content from your own angle with your friend), distribution (e.g. the same content getting specialized for different form factors), creation tools (e.g. environment scanning, object scanning, ...).

Many (see other comments) people are correct when they say that phone AR is not what AR should be. That even the Hololens or the Magic Leap are not it. This will change with time but it's a catch-22. You need some hardware to get more content to get more hardware to get more content.
No they are not, speaking from experience.

How much of research has zero pragmatic pay-off .. until it does ?

-- J. McCarthy circa. 1958
> There are studies that show that certain populations are healthier than others, and we know what they eat.

Going by the top 5 countries: wealth, high-quality healthcare, healthcare focusing on preventative care, strong personal safety and sense of wellbeing, strong community, siesta, favour walking and biking, reduce stress and improve mental wellbeing.

If I recall the findings of one of the longest study ever done on human health, if you want to live long be born with few stressers, genes that is correlated to low stress, and have good access to stress management, regularly exercise the hearth and genuine enjoy it. Don't drink and don't smoke, through they could also be correlating to a lack of access to better strategy for stress management.

We could ask what the diets of Japan, Spain, Singapore, Switzerland, and South Korea has in common, as those are the top 5 countries with longest life expectancy, but it seems much more relevant to look at stress factors and stress management. Cancer rate and cancer recovery in particular is very interesting subject matter in this context.

Diabetes is an interesting side note, in particular to the finding from studies looking at children born around the dutch hunger winter. It doesn't say anything about meat but a lot about how diabetes in part occur when there is a mismatch between how easily it is to access nutrients in the environment and how easy body is expecting it to be. A simplified version is that in one extreme you starve and in the other extreme you get diabetes. A diet that tries to avoid diabetes would be one that tries to match what the individual body expects.
> Reactors do not "consume" freshwater, primary and secondary coolants runs in a closed loop, water never "leaves" or runs out.

That is untrue. They have the same cooling requirements as all thermoelectric power plants do, and some like eg. Diablo Canyon do straight up boil water away. Others heat up lakes or coastlines - which costs (more plant, land and maintenance) and can only be done in some places [1]. Plants cooling requirements are a big part of their overall cost, even with the legacy environmental protection which has led to our current crises.

Just fire them.

It’s painfully obvious they’re attempting to hold back progress that would be beneficial for the entire world.
I encourage reading this, not as self-promotion, but as a first-person history of what it feels like to be too early with a technology.

Someone out there is probably experimenting with something world-changing, and has all the ingredients except for a few more iterations of Moore's Law. It would feel a lot like working on deep learning in 1990. If you think you might be on this path, it's worth studying the history.
The Mahabharat, in which the Gita is played out as part of, talks about the Brahmastra. A weapon that can destroy the entire universe. I don't know if this is what Oppenheimer thought he had rediscovered, nuclear power which has the power to destroy vast quantities of land.

"Now you know why you were taught to never stick a knife down a toaster"

That's the most interesting part of this video to me. I was definitely taught this, and I never understood why because modern toasters don't have this problem (where the insides of the toaster may be connected to a live wire even when off). Funny how this kind of cultural knowledge persists after it's no longer relevant.

It's crazy to see just how unsafe appliances used to be. People maybe don't take that safety differential into account when lamenting the complexity and unreliability of modern stuff.

One other safety thing: it looks like this toaster may not raise small toast high enough to easily grab. Most toaster levers let you manually raise the toast higher than normal to retrieve it. Without a lever you are forced to reach into the hot slot and risk burns or electrocution to retrieve your toast before it cools.
The nichrome wire is under tension in this device.

When the nichrome wire breaks (eventual common failure I think), wouldn't that cause a high risk of the live wire touching the body of the toaster?
Yeah. A collection of personal anecdotes from an internet forum aren't data supporting your hypothesis for all kinds of reasons. Just off the bat, there is some bias in people who visit HN and choose to comment on threads; secondly, there is some bias in the comments you notice and remember.

Extrapolating from anecdotes to sweeping generalizations isn't intellectually sound.

Maybe they want to test their product with a defective component to see how it behaves and make is more tolerant. When I used to do SSD controller/firmware we used keep out of spec flash memory around to test the robustness of our error recovery. There are ways to simulate the errors but the real stuff always fails in mysterious ways.
Indeed. It would be...suboptimal to work for anyone not offering what you described. Anything else is undervaluing/short changing yourself, while enriching someone else.
Go 1.13 has been by far the worse release in my memory. The go ecosystem and community was not ready nor prepared for modules.

Enabling by default the sum database broke a number of codebases that had altered the history of their codebases (either themselves or their dependencies). This should have been an opt in feature for this version.

Changing the way the pseudoversion behaves by expecting a correct date and specific sha length broke a larger number of codebases. This should have been a warning on this version and not cause the modules to fail.

There was one more change that I have wiped from my memory that broke athens. It has to do with how go now looks for a go.mod file in parent urls that caused athens to return a 500.

Overall spent about a week of swearing and trying to fix tools and deps. At the end gave up and moved back to 1.12.
You're adding to my vision about japan cultural gene pool of quality.

Not long ago a bored japan dude made a near mirror finish ball out of aluminum foil.

Seems to be related to the financialization of everything, where financial engineering supplants actual engineering and financial culture replaces engineering culture at the C-level. Here’s a good article on Boeing about that:

The term "technical debt" has always rubbed me the wrong way.

I agree, people from 1999 didn't predict what would be happening in 2019. But why is that considered to be some sort of debt?

Dear Stack Exchange, I am disappointed in you
I can imagine Americans living abroad will be shaking their fist at the parent poster. They have to pay taxes in the USA even when working abroad, never mind in the USA!
Well that is an option. Progressive income taxes are a good thing, I think. I also like VAT as a supplementary method.

We disagree, I guess.
Founder and angel shares absolutely dilute with additional rounds of funding unless you have provisions that are very rare in term sheets and founder agreements.

Excellent points. In this case, we have Bill Gates providing essentially unlimited capital to work out the problems - even if that does take decades.
But your toaster is open to the internet and now it mines bitcoins for some shady character in Moldova.
Yeah, I was referring to outright illegal behavior. I really dislike the "rules don't apply to me" attitude - seems so entitled.

On the rudeness aspect though, I do find cyclists in general pretty rude. I've even seen cyclists that seem to outright seek confrontation by putting themselves in situations that are unfavorable to them. For example, the other day I observed a challenging traffic situation and a driver had to stop mid turn at a corner. A cyclist was coming and saw the whole thing happen, but they still positioned themselves such that a "hook" accident could occur once things started moving again. As soon as the car started moving to complete their turn, the cyclist also moved forward and started arguing with the driver. It looked pretty clearly premeditated.

I don't think you understand how rare your situation is.

All these things are unusual:

1. You joined early enough that you can early exercise for such a low price ($7k)

2. Your company allowed early exercise (still unusual these days).

3. The startup 20x-ed in value (my conservative estimate)

4. You stayed in the job for 6 years!

5. Your startup let you sell some of your shares before exit (This is extremely unusual still).

Still, even with those assumptions this turned out only ok. Assuming you sold everything in December, you made $1.3 million over 6 years, so $217k per year. Considering that for a typical senior software engineer, the equity portion needs to make up about at least $150k of compensation (conservative estimate of a Google L5 from levels.fyi), I would say you did roughly ok, making an extra $67k per year. That's pretty good, but not amazing. Getting promoted to L6 would be more than twice as good.

Sorry for being so negative about your good situation, but I really think current equity compensation is far too low and tricky, and that workers, and especially new workers, should not be optimistic about the benefits.
Yes, and I think the OP would've been better served by linking to the proxy page rather than its privacy policy. I can understand why, however. Privacy, proxies, and private repos are all inter-related but it might not be obvious to people who don't use Go regularly or haven't followed the introduction of proxies.

The problem is that if you don't set up your environment, set it up partially, or set it up incorrectly, some information about private repositories will be sent to Google[1]. One solution is to use the envvar GONOSUMDB (either set from your shell's rc file or, preferably, from `go env`), thus instructing Go which domains it should not validate against the checksum database. Some individuals may not see this as an issue since private repos will fail to download via the default GOPROXY (`go get` should revert to "direct" mode) and nothing gets stored in the sumdb. However, Google does apparently log this information internally, and that's where the privacy issue arises.

For additional protection, you can set GOPROXY to your own self-hosted server, such as Athens, and configure it similarly so it'll reject such sumdb requests with a 403 to catch clients using only GOPROXY. But, you still have to remember to set GOPROXY (at a minimum), which means that if you or anyone in your organization forgets this bit, you're back where you started and you're probably sending information about your private repos to Google. Again.

Since this relies on envvars or the Go env stored in ~/.config/go/env (as an example) to set the behavior globally, you have to assume developers will correctly configuring every system they use. The GitHub issue is mostly centered on having a way to do this per-repository, and I honestly think that would have been a better solution, even combined with the `go env` settings.

Personally, it doesn't bother me too much, because an external immutable append-only log of commits in upstream packages will catch nefarious changes, so I think the benefits probably outweigh the privacy concerns until I see an adequate argument countering this. Regardless, I still have my `go env` set up to ignore my private repositories.

[1] The documentation says Google only logs the paths and doesn't publish them for private repositories their proxy fails to download. I thought I read somewhere that you can still use the sumdb for private repos, but it would instead send something like a SHA256 sum of the path for additional privacy. It might've been a proposal, and I can't find it now.
I wish we had stats on it though. Just my anecdotal observations, but I see tons and tons of cars on the road every day, and maybe a couple of them do those things. Whenever I spot cyclists though, I can pretty much count on them doing something that's against traffic rules.
Unfortunately, the BBC has a questionable relationship with its current audience in its failed modernisation attempt to drive more clickbait-like articles.

Whilst being funded by the tax-payer and privileged enough to have a royal charter to be the UK state broadcaster which has a duty to be fair, impartial and balanced in its reporting, it has become one-sided in several debates siding with hard leftists, aggressively edits / cuts out recorded content (Not providing unedited recordings in full) and has a infatuation of posting irrelevant articles involving cringeworthy memes and young teenage millionaires giving financial business advice.

If this is the nonsense that you'd love to pay your taxes to, then cancelling that BBC TV license sounds like one of the best financial tips in order to save money each month.
This makes 0 sense except in a failing startup where the stock isn't worth much to anyone, including the founders and investors.
When shipping firms moved to shipping containers mid 20th century, the productivity gains were split between corporations and the union to buy out longshoreman so there was a graceful transition out for these folks who were no longer needed.

I didn’t stay for 6 years. I don’t work there anymore. And like I said, the company will likely raise soon, potentially at a much higher valuation. There is a comparable company that is already public that is trading at a much higher valuation.

A favorite quote of mine from Donald G Reinertsen's Principles of Product Development Flow:

Note that the host isn’t saying that this 60s toaster _as designed_ is better in every way— rather, that a modernized version of this design would be better than toasters designed today using the latest electronics.

It doesn’t to me. Had he killed himself it would have been described as lethal. It’s standard practice to describe only what’s known, even when doing so is at odds with how the average person would characterize the event — it may well have been his intention to cause a spectacle without taking his life, so it’s premature to describe it as an “attempted suicide”.

Sure, although there are implementation issues because of the incentive for straw man purchasing. Are you aware of any jurisdictions where low-income purchasers are given additional exemptions?

I would think it would be easier to use transfer payments (like SNAP) to ensure that the exemption is not used for the benefit of non-low-income individuals.

Alternatively, you can have a prepaid or postpaid refundable VAT, where individuals can get their VAT refunded (up to a limit) based on income.
Wealth tax is the alternative. It's a tax rich folk cannot pass-thru.
