The article mentions one big issue: plasma containment. It doesn't even mention what I think of as being the biggest hurdle to commercial fusion power generation: neutron containment.

Fusion hydrogen requires heavy isotopes, namely tritium, to generate sufficient reactions. This generates s lot of free neutrons however, enough that they will tend to destroy what container they're in. This is a significant, possibly commercially insurmountable, engineering problem.

Helium-3 is one alternative but is super rare on Earth ( even the heavier Helium-4 escapes the Earth's gravity once it reaches the atmosphere (so party balloons are consuming an irreplaceable resource thanks to an effective subsidy from Congress who narrowmindedly decided to offload the Strategic Helium Reserve at submarket rates).

People like to bandy about phrases like "free energy" when it comes to fusion. Well, free fuel and free energy aren't the same thing. A plant has a capex and running costs, a finite lifetime and a power output. Put those numbers together and you have a base energy cost even with free and essentially limitless fuel.

The article talks about producing tritium from lithium. Great. The demand for batteries is already going to stretch the worlds lithium supply so that's another advance we need.

That's what I was wondering. Shapeways makes metal parts by a similar process as a service. See their 2009 video.[1] There's a mini-industry making metal jewelry that way.

I notice that Desktop Metal doesn't show their oven in the video. That's the big, expensive, somewhat hazardous unit. "Easily swappable aluminum gas canisters ... safe to use on the shop floor" says the data sheet.[2]

Wazer, the low-end water jet cutter that's still stuck at "pre-order", has a similar problem. They're trying to make a somewhat messy industrial process less messy. There's some hand-waving involved. You end up with a sludge that's a mixture of water, shattered garnet, and whatever you're cutting. They gloss over what you have to do to dispose of that.

"Is there a particular reason the manual and the tools have to be a flight of stairs away from the technician? I'd wager that the comparison would lose some steam if the tech could just turn his head to the right."

I've never worked on planes, but quite a bit on cars and semi-trucks. You can get yourself into some tight spots. There may not be room to bring a manual with you, let alone turn your head to look at it. The closest I've had to glasses is bringing a smartphone to look at a manual or photos - but having it right on your had and hands free would be a huge help.

You have a point, but for controlled fusion the applications look only civil to me. Military application/uncontrolled fusion/H bomb already exists!
Being dependent on someone to survive is not antithetical to freedom. What distinguishes a free society from an unfree one is that in the former, no one violates your right to your person or property, through theft, fraud, violence and threats of violence, as long as you do not violate other people's equal right to the same.

Laws prohibiting private enterprise, or mandating that individuals pay a tax on their private income, limit a person's freedom, as they involve a threat to their person, in a situation where they have not violated any other party's rights.

Freedom does not mean economic security. It does not mean empowerment. These are independent attributes.

Why Does My Cat Like the Smell of Bleach
Perhaps you could link me to an example where that happened? Probably the most famous cases of Monsanto suing farmers were Bowman v. Monsanto and Monsanto v. Schmeiser. In both cases the infringement was entirely purposeful.

Schmesier's case is one where the seeds were initially blown onto his property so that may be what you're referring to. From Wikipedia:

As established in the original Federal Court trial decision, Percy Schmeiser, a canola breeder and grower in Bruno, Saskatchewan, first discovered Roundup-resistant canola in his crops in 1997. He had used Roundup herbicide to clear weeds around power poles and in ditches adjacent to a public road running beside one of his fields, and noticed that some of the canola which had been sprayed had survived. Schmeiser then performed a test by applying Roundup to an additional 3 acres (12,000 m2) to 4 acres (16,000 m2) of the same field. He found that 60% of the canola plants survived. At harvest time, Schmeiser instructed a farmhand to harvest the test field. That seed was stored separately from the rest of the harvest, and used the next year to seed approximately 1,000 acres (4 km²) of canola.

PHP has vastly out-lived its welcome. I'm not saying Java is immeasurably better, it's got a whole different set of problems, but it's an example of a language that's got a better tool-set than PHP ever will.

The debugging tools for Java are really amazing because writing good, threaded Java code can be wickedly hard. The tools for PHP are absolutely anemic by comparison because it's never had the same exposure to enterprise environments.

I'm no fan of Java, but if you're writing Java, you may as well write Java.
I've been dealing with just this issue. I, too, am an introvert and require time alone after socializing to 'recharge.' I had a fairly intense bout of depression recently, I realized that it was in part due to do loneliness. So I did some introspection and talked things over with a trusted advisor.

So some things to consider in no particular order:

Shame about being lonely drives people to feel more lonely. Don't let that trap engulf you.

Take steps to explore your psyche and see if the roots of your loneliness are based in issues like self-esteem. Don't take this lightly. It's easy to dismiss, but if those forces are present in your life, they'll be very difficult to see clearly.

Are you religious? Go to church (or sangha or whatever). Got an addiction? Go to a 12 step group meeting. Like board games? Find folks that like to play and hang out with them. Seek out opportunities to interact with people preferably in the flesh, but online can work too.

Get a therapist. Or a spiritual guide. Whatever, as long as they understand how the human psyche works, and that you're there to work. If that suits you.

Don't underestimate loneliness. There's a reason why our most feared punishment is isolating people. Because it's terrible.

Learn to relish solitude. Don't let an idea about solitude trick you into thinking that being alone is good.

Humans are social animals. Not being part of the herd represents an existential threat to us. This is a major cause of suffering in our species.

Humans are solitary animals. Being part of the herd can be a major stressor for us. This is a major cause of suffering in our species.

Best of luck.

Honestly, that's like a cup of ice water in hell. Composer is a finally thing, and Laravel is a "at least it's not garbage" framework. The things you have to make do with in the PHP world are absurd. Find something in an array? Ugh.

PHP is catching up to what other languages have enjoyed as a given for over a decade. It's very confused. There's been absolutely zero effort to overhaul the core PHP API which is, on the whole, absolute junk. Frameworks like Laravel do their utmost to insulate you from having to use it too much for the ugly things.

As an example of what could happen, JavaScript has gone from this ugly, useless language that would crash your browser if used too much to something that's now widely deployed and powers significant web properties both client-side and server. The improvements to the language have been dramatic, ES6 code is words apart from JavaScript 1.

In another 5 years JavaScript will hit another milestone, Java will evolve, and PHP will still be PHP.

I started doing GTD. I use Calendar for my "hard schedule"—things that I have to do on a specific day and/or time. I use Inbox reminders for my "hey do this if you get the chance." And then I keep my big todo & projects list in Docs. I find they all occupy a slightly different and nice niche—todos & projects in permanent stuff, inbox for "soft time", calendar for "hard time." I find there's a lot of mental benefit to separating these things out. When something is on my calendar, I know that means do it. When something is in Inbox, I know I should just get to it as soon as I have the time and energy. (This works better with inbox zero though; if you have a bunch of other emails etc lying around it dilutes the reminders.)
I've been struggling to begin rehabilitating and changing my home environment.

I went through hell with a series of offensively noisy and aggressively inconsiderate neighbors. So, I avoided home. And I didn't invite people over. And, as the months wore into years, my home took on aspects of neglect.

I was "trapped" at first by some circumstances I didn't deal with well. Then more thoroughly by the self-reinforcing nature of this decline.

Basically, if I'm not comfortable at home, I do not have people over. I lose a big part of my control over my interactions as well as my ability to reciprocate.

Further, since these circumstances stress me so, I don't feel well about myself -- including my inability to more effectively deal with the situation -- and this also causes me to engage less.

And as this is self-reinforcing, so is the attendant, resultant loneliness.

When I do get away from it, I enjoy interacting with people and seem to do reasonably well at it. Well, the "cool" people are still too self-absorbed to accept me. Fuck them -- a lesson too long in learning.

I'm not saying I have "the answer." But my intuition, of many years now, has not changed: I need to get the hell out of here and to somewhere I'm simply more happy and at peace with myself.

Otherwise, half my mind is always at least subconsciously worrying about the monster behind the door. Like neighbors with sub-woofers who would rattle my windows for hours on end.

The article talks about producing tritium from lithium. Great. The demand for batteries is already going to stretch the worlds lithium supply so that's another advance we need.

Can't imagine that this sort of process will use anywhere near as much lithium as the battery industry. It's fusion, after all.

FWIW, Clojure also by default doesn't let you use functions before they are declared but gives you a construct to do it explicitly, which I haven't seen much in the wild. And since Clojure doesn't have full TCO I guess its use won't rise either.

Not the poster above, but I think the main issue is with the cost to provide proof of work in a trustless network. For example, bitcoin is already at or close to the point where the most efficient mining operations have a hard time turning profit without a major bubble drawing in outside capital. 3 years from now it may well be unsustainable.
I tend to use Google Keep (https://keep.google.com/) for this sort of thing, which is similarly pretty lightweight and doesn't impose much structure on anything, but is also permanently backed up and synced between all platforms, with nice mobile apps, and a simple URL you can just type for the web.

It also has some extra support for lists, which is handy for many of the sorts of things that it gets used for, and can handle images to some extent too.

[The one thing I wish it did was some sort of background version control, so when I accidentally delete something important I can get it back...]

This might be a dumb question, but why do terminals spew output anyhow? Past a certain point it's clearly unreadable. Once the terminal starts getting behind this is a UI failure IMO.

So why not (say) buffer it up somewhere, show a preview, show a "I would be spewing output right now, press <Space> to see what the last screen is, press Ctrl-C to stop, press 's' to just spew output". The speeds and amounts of data for which this happens could be completely configurable.

You can always put a limit on how much to buffer up (I'm not saying that this system should completely buffer output files until you run out of disk space), and sometimes 'spewing' is actually what we want.
Help: Everyone at Work Is Demotivated and Pissed
Hi, looking for advice.

The company I work at, we've raised a bunch of money but still haven't nailed a customer solution. The business and product strategy is always changing, leadership is pretty shit, we've rebuilt our infrastructure like three times in the past couple years. The product team and DevOps is constantly is disagreement and my product manager is emotionally tapped out. It's a sales driven company so sales is treated like heroes while engineers and designers are basically forgotten about. My team is losing patience with each other although we're not the problem. There's just a lack of decency in the way people treat each other, people are really demotivated and kind of pissed. There is severe fatigue is people's ability to deal with these issues.

Aside from just moving on - is there anything I can do to just get my team to get along?

This would definitely be a contender.
I'll chime in.

Most chemical processes happen faster with a higher temperature. Some drugs decay into harmful substances (e.g. Aspirin).

Other factors, such as humidity or UV, may play a part as well.

Rather than testing every permutation of storage conditions over time, manufacturers put a safety margin. Individual consumers aren't in a position to remember exactly how they treated any given container of pills. Even if the manufacturer knew how a given sequence of storage practices affected their drug, nobody would be the wiser.
Some options that I have tried and have helped:

- Try Meetup.com. Endless options there. Don't be afraid to be awkward. Read about social skills and practice them.

- Be a better friend and initiate contact with people you know - don't wait for them.

- Also make a list of all people/friends you know local or non-local. Refer to that list and keep in touch. This is harder than it looks but is important. I was surprised how many folks I had a good connection with but did a sucky job of keeping in touch with.

- Attend workshops, classes etc where you have the chance to meet others in a like minded setting. Especially overnight ones. There are always group events happening in urban environments. Seek them out.

- This is going to sound dumb - but try to interact with people via social networks. It teaches you a bit of initiative and also leads to in person quality time in some cases. But be careful that you don't get swallowed by it.

- Have something interesting at your home - like board games, gaming , good list of movies to watch. That way you can feel comfortable inviting people over to hang out at your place and have a good time. It feels nice to say "I have a really cool board game - why don't you guys come over and let's have some fun, along with some beer/drinks"

- Be interesting - if you are passionate about 1 or more interesting topics outside work, and talk about it with folks you meet, they will remember you. It could be AI, self-improvement, meditation/mindfulness, running, fitness, music and so on. But learn to talk about your passion intelligently. It leaves a mark.

>On a related note, I am big into latency analysis and driving down latency in interactive systems.

I'm afraid there aren't many of us that care about the subtle details of interaction that mean the most to one's experience. Working in audio, I know the difference between hitting a button and hearing a sound 40ms afterwards, and 4ms afterwords. I would much prefer to use the 4ms, even if it means sacrificing half of the system's features.

I feel like such a product will never reach the market, because the market will think they need lots of features, which results in a sacrifice of latency and other UI consistencies. There's always some developer writing the weakest link of an otherwise perfect system. For example, the CPU/GPU hardware, kernel, and browser's accelerated rendering are all engineered with millions of man-hours to be as blazingly fast as possible, and then a web developer comes along and puts a single setInterval() call in their online game or something, and all the optimization benefit goes to the trash. Or, because animation is a trend in UI design right now, developers purposely put in hundreds of milliseconds of delay between common actions like minimizing windows, switching desktops, scrolling, opening/closing apps on mobile, etc.

Basically in order for your dream of true virtual reality to be achieved, the principles and respect for low latency has to be maintained across the whole system's stack, especially the higher-level parts.
Fentanyl's therapeutic index is NOT 270 except when used as an opioid supplement for surgical anesthesia cocktails, where the dosage is less a microgram per kilogram and it's balanced with several other drugs and opioid antagonists. The maximum recommended dose for fentanyl is 50 mcg/kg and that requires ventilation because it is well above the estimated LD50 of 30 mcg/kg. The recommended low dose for fentanyl on its own is 1 mcg/kg so at best we're talking about a therapeutic index of 30.

LSD's therapeutic index is unknown because its LD50 has never been established in humans or monkeys and you can't extrapolate from non-primate animals to humans (for example, rats can handle a dose of fentanyl that is a thousand times higher per kg than monkeys can, which is where many of our LD50 estimates come from).
You're confusing freedom in the figurative sense, which denotes empowerment, with freedom in the literal sense, which is a state of living where one is not deprived by anyone else of their right to their person or property through force.

The solutions you propose would limit freedom in the literal sense, through taxation of private property and regulatory prohibitions on mutually voluntary interactions.
So the people pushing fusion say it won't even start producing commercial electricity until after 2050? But by then we will be all on renewables plus cheap storage, or at least pretty close. What would the incentive be for ripping that all out and replacing it with immensely costly fusion plants?
Is GitHub down or just me?
The article isn't, but most of the really egregious price increases we've observed (e.g. epipens, all the drugs that Martin Shkreli bought, etc.) have likewise not been on drugs under patent protection.

In point of fact, most drug companies have faced what are called patent cliffs, where due to troubles in the R&D pipeline[1] drugs lose patent protections far faster than new drugs come online to replace them. While this is probably bad for society overall- we really want lots of new drugs getting discovered and making us healthier![2]- it means that patents protect smaller and smaller portions of the overall drug market. IOW, playing games with them has less and less overall value as the years have progressed.

Need to find new levers to have influence on this market.

This is the sort of medicine that improves humanity, even at that price. There are plenty of other drugs (especially cancer drugs that extend lifespan by averages of <4 months) that do not improve humanity, but Solvadi does. It just costs a ton.
How do you manage to have a consistent logging with atimelogger, without having spurious information? I mean, I can say I'm working, but I can be distracted for a few minutes and come back, or something else. Do you stop/start the timer each time you switch?
