personally I used to burn pretty easily (light skin, freckles) When I was much younger and spent most my time indoors. However I took up multiple outdoor activities and after quite some time in the sun it’s rare for me to burn even after hours in the sun with no sunscreen, and if I do burn it heals fairly rapidly.

So outside genes there may be some sort of adaptation going on.

I'm a reactor designer and I love the idea of open-source reactor design. It's a wonderful way to add some longevity beyond typical congressional funding cycles to these long-term reactor projects. The national labs may have 2 years of funding on gas-cooled reactors, but then mothball those and move to sodium-cooled reactors, and so forth. The lack of continuity is leads to lack of momentum which leads to stagnation. People even forget stuff and have to rediscover it years later.

Also the nuclear industry is small and struggling. Open-source may enable collaboration on a new level that could be really exciting.

Th problem so far is that the nuclear industry is really secretive. We like to think we have the best design, and all other designs are goofy. We like to patent things and protect secrets. The nuclear industry started in secrecy, developed in secrecy, and still has a lot of it.

But it's struggling so much with cheap natural gas and popular intermittent renewables that it's kind of a do or die situation. Open source is a brilliant step.

All that said, reactor projects don't run themselves. Transatomic shut down and open-sourced their design. For it to go anywhere, it needs dozens of well-funded or otherwise highly engaged people managing the project. Nuclear builds are about as complex as projects come and simply open sourcing it won't go far. So the next step here is for the nukes to agree on a particular open source design, fill in a business plan, and start going. In any case it's exciting times.
I'm having difficulty parsing this. Are you claiming that leaders of the United States are deliberately working to decrease life expectancy in the country to reduce the population?

Couldn't agree more. I like Serif fonts, but they are hard to find in monospace form.
I've known about the Input fonts, but their license is too restrictive. Recently I discovered two that are open source: Courier Primer and Go Mono.
I have switched to Go Mono as soon as I found out about it, even though I was a long time Source Code Pro user

I think this font deserves to be more widely known.
I meant food security in the sense of consistent food surpluses and not facing periodic starvation.

Americans today throw away about 40% of the food produced, and are the fattest people on the planet.
The rug does need to be pulled out from under capitalism. Our relentless march for ever greater profits and "productivity" is what's dooming our society. Until we put the future of humanity, of life and of the environment above profit and everything else, we are doomed.

While we do need to act as individuals and we will have to accept important and significant lifestyle change, the greatest changes will have to made in industry and shipping. We need to stop the massive exploitation of the environment by industry and big business.

Your reaction is perfectly normal, it's hard to accept that we're standing face to face with our doom. Your approach appeals to a more "sensible, step-wise and piecemeal approach", one that won't inconvenience people too much.

How would you suggest that approach would work? Gradual reduction, slow adoption of more sensible policies over the next century or so? What is your proposed solution, that will actually be effective enough to make the required change?

If we stick with our current systems, at the very least we need politicians who realize that the environment is our #1 priority, above anything else, and are competent enough to sell that message to the public. And to convince people that massively reduced consumption at all levels is the way forward.
Ironically, can't a lot of the mortality increase be attributed to the tightening of prescription opiate supply? A well intentioned measure seems to be resulting in a fair amount of people dying. Maybe the lesser evil is to just let people dope themselves up with pharmaceutical-grade controls on purity/dosage?

That seems a bit strange.

Here in the UK, I don't have a prescription (despite being type 1 diabetic) but occasionally self-fund the devices directly from Abbott. I get a VAT excemption so it costs ~£45 per unit, which lasts 2 weeks.
There was not a clear understanding what the vote was about. There contradictory promises being made about what a Brexit would mean. It would mean saving tons of money that wasn't there, staying in the common market for goods and services, yet somehow leaving the common market for labour, except maybe not when it benefitted Brits. The whole campaign was a bunch of lies, and those lies are what informed the people's vote.

There was absolutely nothing clear about what a Leave vote would actually mean. It makes every sense in the world to hold a new, more honest vote once that has become clear. It's a betrayal of democracy to plunge the country into such an ill-advised and irreversible direction based on a single, poorly defined and poorly informed vote.
These concepts make more sense after one has been exposed to quantum mechanics. One of the first things you do in an intro to quantum mechanics class is calculate the energy levels of a Hydrogen atom (and then Helium.) Chemistry is literally applied quantum mechanics; and everything in quantum mechanics is probabilistic. A more accurate picture of an orbital is that it’s an energy level where a cloud of probability mass lives that corresponds to, if one were to take a photograph of the atom, the likelihood of finding an electron in any given location (wave function collapse.) But before a measurement, the electron really was a cloud of probability mass.

To everyone who is very smart in here saying "MAC addresses are not unique, MAC addresses can be spoofed".
The article is about German police trying to find a criminal using one public identifier.

> in my experience [slackers are] rare (and 100% protected by management)

Can you give an example of how you see slackers being protected by management? I wonder if we have the same definition of the word slacker.

In my experience the people protected by management are not doing much in terms of daily work, but they work a lot to always stay on top when it comes to prestige and taking credit from other people's work. So from my perspective they are working hard, just not to improve the teams results. That's why I call them parasites. They suck out the value of the team for their own gain.

What I call a slacker instead tries to do nothing but reading facebook (or HN) all day. Most of the time these are people who have given up hope to improve their careers for one reason or another. In many cases it is connected to a parasite sucking too much out of them and them not being able to recover self-motivationally.

I bet at least before readign this post your understanding of slacker and my understanding of parasite would be similar, right?

We need to focus on reducing production, with reuse as a secondary and complementary measure. We have a ton of disposable crap and packaging in our lives, much of it is inherently garbage. Reuse what we can, but reduce the production of things that become waste.

Magic? It's aesthetic, but technically it's simply a circuit that with the wires woven together instead of printed in traces on a board. Magic-like tech is the reverse, the amazing minituarization of circuitry to microscopic size.

I get why the corn was funny, it makes sense to me having depression. She was feeling really down, everything was pointless. She was on the floor at her lowest. Then she saw a very concrete example of something just as pointless / sad. A corn under the fridge is going to be alone, forever (or at least until the fridge is moved). I think it probably felt like relief, she wasn’t alone. Someone understood. That’s what she had been missing throughout the blog post.

It's simple enough and easy enough to access that it's the only way I can stick with this setup unlike every other setup and app I have tried.

My only negative is that it is yet another variable that has me entrenched in the Apple ecosystem. So, despite not exactly the most impressed with the current MacBook Pro (2017) I own the time and convenience it provides I feel has made up for it.

I realized I wrote weeks - the transmitter is good for 3 months and gets flaky in the last couple weeks.

I found some pictures of someone replacing the battery on the transmitter of a G6. This is.... not really practical. [1]

What would be interesting is if you could pull out the internals and 3D print a new enclosure that had an actual user serviceable battery.

Cryptography is like civil engineering or surgery. If you're going to do it in production, you need to do it right.

I think it's akin to a family physician saying, "this is best left to the surgeons."

Don't be fooled that just because you can write code, you can do crypto. But also, you can learn and you can also completely mess around in a safe, non-production environment.

Maybe my analogy is a bit weak.
IIRC, it's barely a concept in English law, primarily US law.

It has however seen some use in the ECHR , notably against Germany (citing various US court cases):

> the applicant sought a declaration that [...] all items of evidence[...], which had become known to the investigation authorities because of the confession extracted – the so-called “fruit of the poisonous tree” – was prohibited [...] The Chamber considered that there was a strong presumption that the use of items of evidence obtained as the fruit of a confession extracted by means contrary to Article 3 rendered a trial as a whole unfair in the same way as the use of the extracted confession itself.

Gäfgen v. Germany, at 25 and 147 https://hudoc.echr.coe.int/eng#{%22dmdocnumber%22:[%22868977...}

It almost certainly wouldn't apply here though (as there is no illegal act).
Which "powers" want to decrease the population?

Most wealth in the US is generated by consumerism, so "powers that be' in the US should want to keep people alive.
If you return other people’s bottles because they are willing to forego the deposit, then you do make some money. One of the ways that I survived my time as a skint foreign student in a Nordic country was picking up bottles in the city center on a Friday or Saturday night when everyone was drinking in the street and couldn’t be arsed to hold on to their bottles and take them back for the deposit. (I hear that now students find it harder to make money like this, because Roma immigrants have cornered this line of work.) Even later when I wasn’t so poor, there is pleasure in hosting a BYOB party and then being able to get the deposit for all the bottles and cans your guests brought.
Do projects matter for IT? (2011)
As I remember it, the book SICP itself wasn't really the core of CS61A... the lectures and slides were, and they drew off the concepts in SICP. No one read the book, but we learned from the (fairly good) lectures and explanations of the concepts, and especially the projects of course.

Those concepts were and remain a foundation for how I think about programming—at the level of elegant structure and short modular thinking. Software engineering and architecture is something different, and has its own class (CS169) which was far more valuable and important for those skills at that higher level.

I dunno. It was a good foundation. I've looked through SICP and I still recognize the concepts, the lectures matched it fairly well. But you're right—no one read the book.
That Argonne reactor uses molten sodium, which explodes when it touches water.

The open-sourced design uses molten salt, which is the very stable stuff you probably have in a shaker on your kitchen table.
A better title would be: "Show HN: SuperPay, payments for [target audience] that [what you do differently]"
weechat + wee-slack.py works quite well.
It would be for say AGA stoves but I take your point
The `createCipher` API derives an IV from the passphrase so basically it uses a static IV for each passphrase.

If you used it and need to switch to the new API but be able to decrypt old stuff, here's some code to get the IV that the deprecated API actually derives, so you can use it with the new API: https://gist.github.com/bnoordhuis/2de2766d3d3a47ebe41aaaec7...
This thread by Atul Gawande, a doctor, analyzes recent death data from Massachusetts. Several interesting notes, especially this: "The starkest differences in death rates are not by race or gender, but by level of education. People with only a high school degree or less have a 350% higher annual rate of death than others. That's not a typo."

In some countries they actually do give such referrals. But it's rare in the US because most insurance plans don't cover such treatments. That is starting to change to a limited extent; my retired father receives a discount on his medical insurance for going to the gym every week.
You're thinking of sodium. This reactor uses salt, which is very stable, just like the salt on your kitchen table.

The lack of any sort of driver for chemical explosions is one of the advantages of molten salt reactors over light water reactors, in which the water can split into oxygen and hydrogen and cause explosions (as we saw at Fukushima).

This was very relatable. In some cultures, becoming disinterested in the world is not seen as something wrong - you end up a monk as one example.

It's really, everyone else not knowing what to do with you that causes so many problems. If we viewed it as ok that a few % of the population will want to drop out of playing along and simply do their own thing without harming anyone, we'd be in a much better place.

As someone who relies on udacity's app to follow a couple of courses in scenarios where I don't have internet access (say, in a flight) this news is very disapointing. It feels like a sort of bait and switch.
I agree for the cookbook. I'm building a lang I have scavenged so much info from so many places, but all is kind of disconnected. Or worse, all stop at generate the AST, and barely interpret the AST at the level of a calculator and maybe simple functions.

For example, I need like 5 different sources to finally have a grasp in how pattern match, and build a solution that later found in another paper.
Almost as ridiculous as "Silicon Valley is evolving and focusing on employees" I'd say.

That could also be explained by there not really being many other options. I don't think too many people really wanted to send postcards with Lenins and red flags for holidays, but if this is all you have, you'll buy that.

By a similar token, Brezhnev's "memoirs" (Малая Земля etc.) were published in millions, but I have never heard of anyone who wanted to buy, let alone read them.
I was one of those people fixing it. How is it insulting to say that the biggest impact was the enrichment of the people working on it?
Five is right out.
I can understand why the sensor will expire, but why does the transmitter expire? Shouldn’t it just require changing a battery?
Open-source licenses usually just deal with copyright. Patents are another obstacle to overcome if your company/organization/hobby has a need for building salt reactors, but overcoming copyright is a push in some direction.
I generally use jsfiddle for these kind of things, but AFAIK it doesn't do es6 or Typescript, so RunJs looks like it's worth a try.
A new report from the Centers for Disease Control shows that a small decrease in life expectancy, from 78.7 to 78.6 years, is part of a continuing trend. Even as we make progress treating cancer, heart disease, and stroke—three of the biggest killers—we’re losing ground on other fronts and have been since 2014. That makes this continuous decline unlike anything we've seen since World War I and the Spanish influenza, which both happened between 1915 and 1918.

Had to re-read 3x times to make sure I was not misreading. Just .1 year? Isn't that within the margin of error or just an expected fluctuation within a much longer trend / hardly anything to lose sleep over, IMHO.
I have to focus one one project, at the moment i'm writing a programming language and i've pretty much got there by saying to myself "ok, i want to do this.. what language features do i need?" and work from there.

I think this can apply for anything. Work out what you want to do, then the steps that you need to do it.

It doesn't really matter whether you use trello, a text file or some other notes system.

Don't try and do things in parallel, it doesn't work. If you want to do some big project, save some money so you can focus on it. Work out the outer logistics as well as the inner.
What's wrong with udacity's app? It enables users to buy course subscriptions and follow courses even when offline, and does so painlessly and efectively. What else is it missing?
> ...can't a lot of the mortality increase be attributed to the tightening of prescription opiate supply?

How do you figure that?

To the contrary, this article lists drug overdoses as one of the three main causes for the decrease in life expectancy. Wouldn't increasing the availability of opioids increase overdoses?
Very cool if you are a rich audio geek who wants to impress fellow vinyl nerds with your conspicuous consumption.

I used to stay in contact with a group of friends who now exclusively communicate via slack, until slack eliminated the IRC gateway. Now I've lost contact with that group, it's quite irritating.

> you can move it off your property

And where should I put it? I don't want it on the sidewalk, and I don't want it in mystreet. I can't put it in the trash because it's someone else's property. That's essentially what I meant by "anticipated solution."

Note I never suggested it would become mine, so a good portion of your comment is responding to someone else. And I'm not sure who you are referring to by "you guys," but I can honestly say I have never before been in a situation prior to these scooters that someone just left their valuable stuff on my private property and I had to deal with it. Are there equivalents to towing companies I can call for random valuable crap that belongs to someone else?
When my family was on vacation in Greece the lifeguard told me he could always recognize the American kids because they were the only ones wearing shirts in the pool.
Thank you for this much more nuanced response. Your original post was very critical of SICP in a way that didn't seem to do it justice - I think that's what set of much of the debate in this thread. But if what you say in this comment is what you really meant, I fully agree with it.
Mp3s don't support video, and video is of vital importance to the vast majority of courses, specially IT.

Can you point to an example or two where RDF is a "fantastic way to aggregate data..."? My sense is that things like microformats, which are more flexible and narrowly defined than RDF, are useful for this, too, but it hardly constitutes a "semantic web". It's just obvious connections between things. Something like a custom type of hyperlink is all. Not that this "all" is bad, it's just not going to revolutionize the world or anything more than the existing web already has.
