That is a great paper[1], thanks for the reference I've added it to my nuclear effects library.

It doesn't involve the China Syndrome speculation though, what it does find is much much more interesting.

The paper reports that beach sand is capable of 99% adsorption of Cs137. And then goes on to discuss how it gets de-adsorbed (up to 11%) when Cs137 free sea water is mixed with it. What this says to me is that you can use really cheap beach sand to filter the discharge water from a nuclear reactor and collect 99% of the Cs137 in the water which will stick to the sand. The sand in your filter can be replaced and the cesium rich sand can be sequestered for the Cs137 to decay over time.

This is an excellent finding that suggests reactors have a reservoir of sand for pumping cooling water through especially during reactor compromise. Knowing this a future even would release significantly less Cs into the ocean, collecting it instead in the sand filter.

[1] The experiments showed that beach sands have an adequate ion exchange capacity for this level of 137Cs, with an average adsorption fraction of 99% regardless of the salinity, sediment grain size, or mineralogy (Table S3). ---https://www.pnas.org/content/early/2017/09/26/1708659114
Good points, although in this case allowing outgoing access to YouTube already allows unrestricted exfiltration of data (you could send a PM or post a comment on a video)

'Perfectly usable' is a bit of a reach given how huge Motif was at the time. I shudder to think about the size of a directory with a bunch of X applications that each snarf in all their dependencies; remember we're talking 1990s.

> It was actually mandated for many government projects for a while

I have no clue about this, but I suspect that the government, rather than mandating a software development methodology, simply used to agree beforehand on what was to be delivered and expected to have it delivered at the end of the process. It's a constraint on how you sign contracts with external suppliers, not on how you write code- though I understand that the first influences the second.

As an extra treat, Google Home isn't compatible with some older devices that are still perfectly functional. We use a Gen 3 iPad (max iOS version = 9) to control a few bits and pieces, including being a handy way to cast online streaming services to the big screen. Until one day the Chromecast gets a bit confused, as they do from time to time... and the Chromecast app on the iPad tells us in nauseatingly cutesy fashion that we should get the latest version... and redirects us to a different app on the App Store (Google Home) that isn't even compatible with our device. Literally, one day it all worked fine, the next day the whole setup is completely broken.

>Making yourself wealthy doesn't necessarily make everyone better off. The social welfare cost of wealth creation is not always the same.

No dispute there, but if people are engaging in counterproductive wealth transfers, there's a case for intervention and we don't need to amend the tax code for that.

>If you couldn't trade money for interesting machines, then you'd likely do something else with it.

Not really, I'm not super interested in luxury / the simple pleasures in life are often enough for me. I would work to make sure I could afford hamburgers, but I'm not the sort of person who would put in additional effort to eat steak. If I couldn't play with machines, I would play with my mind and recreational drugs.

Taxation isn't the only thing that discourages work - regulations on what we can buy and how we can use it discourage as much. If supersonic flight were more legal, I can promise you that I'd buy a jet, but since that's not an option, I'm saving the money for early retirement.

If we're trying to design a policy that encourages people to do productive things, we can have a rock talk. However, if we're simply trying to eliminate wealth gradients in a way that makes materially poor people better off, understand that's a one time event. And there's usually a reason poor people are poor, if they squander their one-time redistribution money, you're really going to wish people were out there working and producing surplus value for you to redistribute to those who can't take care of themselves.

3. Again, I don't dispute the ROI of this investment. My point is that we have more investment opportunities than we have money. Malaria nets, childhood nutrition, primary schooling for girls, etc - there are great places for us to park money. How would you prioritize?

4. Why stop at precious metal toilet seats and houses? Why not redistribute everything owned by above-median wealth holders to below-median wealth holders and erase any gradient of material well-being?

Again, my concern is redistributionists tend to offer no limits on what they want to distribute. This is the same line of attack that incels use to advocate for redistribution of sexual access.

Marginal utility of money. After redistribution through a luxury tax, the same craftsmen could make say 100 smaller yachts at the same cost as one mega yacht, each with less status appeal (which is zero sum), and on net increase wellbeing more.

That's not necessarily how the taxes were structured and the money might have gone into other things that hurt luxury yacht craftsmen.

We'd probably be better off with even one smaller yacht and paying the craftsmen to dig holes and fill them back in with the excess time. Less status to the yacht-buyer, but the same goes to his competitor buyers so it probably nets out, and then you have less exposure to fiber-glass dust and solvents and stuff for the workmen who are now doing something just slightly less productive from a marginal utility standpoint. Probably a net win overall.
You should perhaps consider if you are modeling the behavior that you want to see others adopt. They don't know your relationship status, they only know that you find it acceptable to be rude and dismissive in a professional environment.

Newcomers, outsiders, and others will take that experience to heart.

I've met a dying Chernobyl first responder on a commuter train in Belarus, back in early 1990s.

These people never made it to WHO statistic as their deaths protracted over many years can not be directly attributed to the accident. As pro nuclear crowd would be happy to tell you, only couple dozen firemen died on the first day and that was it, making nuclear meltdowns almost benign incidents.
Ask HN: Getting More “Technical”
I am a Product Manager at one of the major tech companies, and I have an inkling that I want to get more "technical". Specific motivations behind this include:

1) Feeling more and more like Product Management is not a long-term valuable skillset/discipline and want more hard skills to maximize career potential.
2) Want to found a startup and not be 100% reliant on others to code everything.

Unfortunately I don't really know what it means to become more technical or indeed how to measure progress against this goal. I have taken a few coding courses and generally can have good conversations with engineers about product strategy, but otherwise this is undefined.

I know this is a fluffy question but I'd like to get the wisdom of this community on the following:

1) If you've ever thought of someone as being either 'not technical' or 'technical', how did you define that term? I would love to arrive at one definition for this term.
2) What are some recommendations for how to make and track progress against this idea?

Leaving it intentionally open ended- thanks.

True, although Visa card circulation far eclipses MC, so you could take the gamble that they'll have a Visa. Last I checked, Visa actually had more cards in circulation than all three of the other major brands combined.

Slightly old info, but:

I've been to the edge and back. It never occurred to me to call a hotline and it never would, but I have no doubt that other people might benefit from it. If the prospect of saving a life isn't enough to get past some abstract hand-wringing then I don't know what is. The point of the hotline isn't to fix you or permanently stave off a desire to kill yourself. The point is to buy enough time for you to get real help.

Dude. Full sentence quotes please. I should have used a comma.
To be human is the ability to defy our instincts. From the simplistic "I choose not to eat", to the extraordinary "I choose to end my life."

I strongly believe that suicide is only a cultural taboo, and thus it is 'safe' to label it as a mental illness.

I have struggled with wanting to end my life for 35+ years. "Talking about it" does not work. Medication/Meditation/Mediation has not helped. To put it simply; I do not wish to exist.

I tried to kill myself once. [Dammit i suck at everything! /joke]
Not a single day goes by where I don't think about doing it again. I regret failing.

And yet I get up and go to work every day. There is a momentum to living. It is just a habit. I take no pleasure from my hobbies. I no longer have solace within peace and quiet. I am unable to escape in the written word.

If I could end my life and know my family would be cared for financially I would in a heartbeat. My obligations keep me alive, and it is a torture.

I am surrounded by people who love me, and would be devastated by my death.

As near as I can tell, this is the meaning of life; and I want it to end.
Visa/MC are essentially the Uber of credit. The banks provide the credit lines and Visa/MC take a processing fee to use their networks. Amex is a pure play. Paypal in store is one way to avoid the CC network.
Wireguard, libsodium, go's crypto libraries and Google's Tink have all implemented xchacha20-poly1305. I would not say that it's not a thing, but I would probably wait at least until the ietf process is over before using it.
But various tools have implemented the W3C proposal; just not browsers yet, probably mostly because getting the UI right is tricky, and the risk of breaking things higher. The problem is not in the particular syntax, but the feature as a whole.

I'm not so sure this is a great idea, quite commonly when reverse engineering something I need a good reliable implementation of a dated cipher. MD4 is still used in NTLM, RIPEMD160 is still used in Bitcoin and other cryptocurrencies, etc.

Systems exist outside of the Go ecosystem and not all systems are new. Compatibility is important. It's great to flag these as not recommend for new designs, but it's quite another to remove them entirely and prevent people from easily implementing compatible software. Seems more like something that should be in the documentation or spit a compiler warning if that isn't deemed loud enough.

MD5 is similarly broken but I'm assuming they don't want to remove it because it's still quite popular in some use cases - what exactly is their standard for that popularity?

Maybe, but they were only possible because web developers had started considering Firefox in addition to IE. Even then the amount of time spent reverse engineering IE behavior was absurd - when webkit forked khtml it could not render yahoo.om correctly (it mattered then ;) ).

This post is saying you only need to test chrome because it’s 80% of the market. Back in the day IE was more than 90% of the market.

If all you do is test on chrome you force every competitor to reverse engineer chrome (you can’t fork chrome to make a gpl browser). Alternatively you give up and just use chrome (skinned or not), and that dictates the features you get (I don’t see chrome getting built in tracker blocking any time soon).

You can’t use alternative browsers because the web is filled with sites that are only tested on chrome.

Congratulations you have recreated IE.
Roku and Amazon Fire TV works fine with captive portals though (Roku elegantly asks you to connect to a custom WiFi AP that just forwards the captive portal to your phone). So this is another case of Google making assumptions that limit their devices' usability.
As I understand it,

You're traveling at the speed of light. You have your perception of entropical change and an observer has theirs. There is no singular time that "exists". There are multiple perceptions that "exist". Time itself is not existing, as much as it is a perception of process(es). Humans mark states and compare later. This is not time, this is a measure of states. The term time is a shorthand for that, to the detriment of comprehending/understanding what it (the term Time) is describing.

To an extent it is the government's job to police rural areas. For example if a rural area says that no gay people or no black people are allowed, should the government not step in and allow then to self-govern? Should they be allowed to lynch whoever they want under the guise of ensuring cultural homogeneity?

That would also fall under the rallying cry of homogenous culture you've been talking about, as those same rural people fear gay people or black people for similar reasons as immigrants. And the reason why I use such strong words is because this is the exact excuse the KKK has used in the past to demonize other minority members of a community.

And the rallying cry of abolish ice is nowhere near the level of the demand for the wall, considering we have very prominent examples of ICE abusing it's authority, from deporting actual US citizens to harassing communities. If a branch is thoroughly corrupt then I would hope our officials would listen to the voters when they demand reform. And that reform involves tearing down ICE and building a better agency.

In a population of > 1 billion where access to schooling is spotty, and the quality of said schooling is spottier?

"Critical thinking" is a state of mind that takes generations of progress to develop, and can still be reversed. The US population in general may be more educated on average, but if presidential opinion polls are anything to go by, a minimum of 40% of the population arent' practicing critical thought.

Yes. Under the Hukou System (https://en.wikipedia.org/wiki/Hukou_system), children could only attend schools in the area where your household was registered. If had a rural Hukou, and moved to an urban area to get a job, your children would not be able to attend school in that urban area. You had to leave them behind in your rural area for them to attend school. There have been reforms to the Hukou system in the last decade, so it's not as harsh as it used to be, but it is still much better to have an urban Hukou than a rural one.
Is it possible that this financing proposal is just Alphabet's attempt to offer an alternative to local governments that would be reluctant to commit to directly fund these high-cost developments? Google is pretty evil, but this project has been moving very slowly and has been relatively responsive to public concerns. They're not trying to pull a fast one on the city like Amazon and NYC.

As a resident of the neighborhood under discussion, I would love to see it developed. I'd rather not offer Alphabet this incremental tax revenue, but I'd accept it: that would be a tiny fraction of the value the project would create for the city, and potentially for the world if some of the experiments are successful and spread.
But if you get 2% and they charge 2% you're stating their fee is approaching 0.

I might be a bit too cynical about this topic, but it really should be obvious to anyone in the field that you're not on track to become a PI this way.

If you want to pursue the academic career, you need to focus on that from the start of your PhD. And you really need to be on some position on a track towards full professor after one or at most two PostDocs.

I'm quite confused by the timeline here, though. A PostDoc is usually something around 2 years, maybe 3. Four PostDocs in 23 years is unusual, and indicates positions that are closer to something like a staff scientists usually done by people with permanent positions.

Trump was elected on a platform with only a few big goals, and one of them was "Build the wall." This became something of a chant for his supporters. Now that Trump is president, shouldn't it be his duty to try very hard to make it a reality?
