The specific EAST reactor [1] mentioned in the article is a testbed that will enable new technologies to be used on the ITER project. The ITER project [2] is currently the largest fusion power research project underway (and the largest reactor under construction). ITER's goal is to provide research that enables new technologies to be used on the DEMO project. The DEMO project's goal [3] is to provide commercially available power plants utilizing nuclear fusion.

From ITER's wikipedia page:

>The goal of ITER is to demonstrate the scientific and technological feasibility of fusion energy for peaceful use. It is the latest and largest of more than 100 fusion reactors built since the 1950s. ITER's planned successor, DEMO, is expected to be the first fusion reactor to produce electricity in an experimental environment. DEMO's anticipated success is expected to lead to full-scale electricity-producing fusion power stations and future commercial reactors.

And from DEMO's wikipedia page:

>As a prototype commercial fusion reactor, DEMO could make fusion energy available by 2033.

Sustaining fusion is very difficult (we really haven’t solved it yet!). Runaway fusion is only really possible if you can simulate stellar conditions, which requires extreme amounts of energy that must be fed in continiously to maintain temperature and confinement. Plus, the radioactive byproducts are much shorter-lived, and so pose much less of a risk of causing lasting ecological damage. Also, just as a FYI, the LHC has not produced any mini black holes or magnetic monopoles. Anything of the sort would be a major accomplishment, far surpassing the discovery of the Higgs Boson.
Maybe we have different definitions of thought but there's definitely not a lot of in-depth analysis and due diligence in most deals, as that's how portfolio theory and sufficient deal flow is attained.

What you're talking about with IPOs is not quick or easy, and definitely not guaranteed in any way. Taking a company public essentially counts as an exit for most funds, and if it was that easy to just sell up everything then the entire VC field would look different. That process is more for private equity and banking firms who maneuver through financial engineering rather than early and mid-stage VCs.
I agree with that personally, having a trademark for a particular colour is clearly a dubious concept.
So you think we need to trade the occasional waste of some ingredient you didn't use (and didn't bother to give to a friend/neighbour) for wasting ungodly amounts of plastic on small packaging?

(I know this is happening and will continue to happen - and this is how market choices contribute to the climate change and destruction of environment we live in.)
Are you serious, you free millions of human beings from the drudgery of driving people around. You make billions of people be closer to wherever they want to go. Its a transportation revolution, akin to smartphones. If they work, society will be completely different within a decade.
A system of particles in thermal equilibrium will contain a small fraction whose kinetic energy exceeds the average by a factor of 10. Also, the energy available in the center-of-mass frame of two colliding particles is higher if they happen to be moving in opposite directions. That could give you another factor of up to 2. In any event, I don't think you want your fuel fusing all at once!
There's most likely not even a risk to the experiment itself from runaway plasma. Experiments like these use very low-density plasma (mBar) so despite being extremely hot, it's a fairly low mass overall of heated plasma. These experiments regularly lose deconfinement of the plasma within the magnetic fields and it collides into the inner walls of the tokamak and cools back down. This is the main thing these experiments are designed to study: how to keep the plasma stable for longer. Even if there were a larger and hotter mass, we don't have the pressure from gravity here that makes fusion work in the center of stars, so it will just kinda melt things and then cool off, if that.
Fusion is not a chain reaction. The energy maintained for this is incredible and it can’t run away. Fusion has no toxic or radioactive bioproducts.

As a power source fusion is pretty good, which is why it’s such a target for research.

I was talking to a buddy that does construction work in a pretty wealthy area (Scottsdale, AZ). They are just finishing up a large luxury apartment.

Apparently, the contractor let the drywall get soaked while sitting on palettes during monsoon season, and since the roofing wasn't done there were inches of standing water that resulted in black mold.

They just drywalled right over it. In the US. In 2018. In a luxury condo.

So, you never know what nonsense you will have to put up with.
Edit: plants do nothing to particle matter in air they can soak up co2, benzene, formaldehyde etc but do ample resesrch before placing plants in your bedroom. Typically snake plants are fine in bedroom as they don't give out CO2 at night.

There is no need for an air purifier if you have ample light in your room. Just plant a few indoor plants

Peace lily

Rubber plant

Snake plant

Spider plant

Aloe vera

Money plant

Orchid

NASA has done a study in the 80s and these plants have purified a lot of harmful gases including Benzene, formaldehyde, CO etc

Please use more plants!! And on top of that few plants like Snake, Aloe give oxygen during day and night so they are refreshing (as in they don't just clean air they give oxygen as well) and plants are cheaper and require just water and fertilizer every once in a while.

I own 40+ plants in my balcony garden itself. I've experienced these effects first hand!
> Maybe an intermediate solution would be to use integrity hashes on the remote calls.

That was my immediate thought upon reading your comment and realizing that the bar to hit is really to be just as secure as if it's baked in the binary, but on reading the bugzilla links that _rfk posted in a comment to your original comment, I'm not sure it really works for their goals (whether or not you think those goals are correct or match yours).

If I maybe understand what they are working towards, it's having the flexibility to provide fixes/features quickly while still providing security. I'm not sure the features portion of that is as important as the credit they give it, given we're talking about security here, but quick fixes is good. I imagine they are looking at a way to provide a specialized context or something similar to lock down what can and cannot be done if the served content is malicious, but I'm not entirely sure what that would look like.

https://news.ycombinator.com/item?id=18004980 Calculations have been done in general about runaway fission/fusion already. Hawking showed that mini black holes "evaporate" very rapidly, before anyone would even notice.

As for some unexpected pathway, energies like this are reached in stars all the time, and they don't spontaneously explode on a regular basis. If you're talking about a basic science experiment being the Great Filter -- well, maybe. I'm skeptical.
Both, really. The goal is figure out how to sustain this for an extended period of time.

It is incredibly high. We hold it in not by any material, but by magnetic fields. Plasma has the handy feature of being magnetic. The Tokamak[1] design used in ITER and this example uses a whole heap of magnets to hold this plasma in a doughnut-shaped area.

That's not a discussion of purposely harming competitors, it's partisans being partisan -- and getting shut down by internal processes designed to prevent exactly that.

Large organizations don't prevent misbehavior by hiring perfect humans. They do it by having layered defenses against it. The fact that the partisans failed is if anything evidence that the internal controls are effective.
I feel your pain. I also have a wife and two kids and have been through this. With poor web dev skills going into it, I tried to build a doctor appointment booking marketplace. I eventually got my MVP done, but the practice I trialled it at didn’t really buy into it and I didn’t have the time to spend with them to get them up and running properly. Plus, there were some intermittent sync issues with their system. Meanwhile, Healthengine pivoted into the space and took off.

By the end of it, I was a much better web dev and I’m doing quite well in the contracting market in Sydney. I’m still tinkering with side projects, but deliberatley avoiding unrealistic ones.

Well, they kind of do…

But really, the only reason why stars manage to stay in hydrostatic equilibrium is because of gravity, which we really can’t do on Earth so we settle for fancy magnetic confinement vessels.
I think people like you are not the target market for this kind of product -- you care what your food looks (and tastes) like, and are willing to put the time in to choose it yourself.

Then there's people like me -- I don't really care too much about getting the perfect vegetable, as long as it's not spoiled and tastes reasonably good, I'm happy with it, and I want to spend as little time as possible -- I'm happy to pay someone else to choose if it it means I can escape a visit to the grocery store.
I will add:

- While the products of the fusion reaction are short-lived, operating a fusion reactor will active materials in the reactor and create some longer-lived radioisotopes.

- Unlike a fission reactor, which is loaded with months to years worth of fuel, a fusion reactor would have fuel constantly injected. So operator action to stop injecting fuel would stop the nuclear reaction.

What? I have read the report myself. They put in Benzene inside a sealed room and one of these plants. A few hours later the Benzene was gone! Absorbed by the plant.

They did the same with formaldehyde too and other harmful substances.

Have you tried writing it out on paper as a flowchart?
Sounds old school, but can help with visualising what's happening.

Loops become super simple when you see them as series of steps with a yes/no question of whether to stop or go through your steps again.

Draw up some boxes for every variable you think you're going to need, give them labels and add the labels to the flowchart.

This then allows you to run through the flowchart step by step changing the values in each box as you go.

Blockchain Scalability with Sparse Merkle Trees and Bloom Filters
Did you read the article? The system is designed so that an authentication token is derived from the password, and this token, rather than the password itself, is authenticated against on the server. Since the encryption key can not be derived from the authentication token, this shields the content of the encrypted data the server stores from itself.

GP rightly noted that deriving the authentication token with code served by the server at log-in time renders most of the security architecture of the system rather moot, unless user has the time to verify the JavaScript they are served every time they log in.

Different horses/ platforms for different courses. I use FB, Insta as a virtual blog of what's going/ went on in my life. I don't post every single thing, but upload stuff which stands out for me. I joined FB back in '04/05 in my college freshman year (christ, I am old!) and it's nice to scroll back and see how my friends and I evolved over the years. All those moments, dare I say, even silly pics/posts, are nice to go through sometimes. Same with Insta, but obviously, here it's all about just pics and focused comments on them from friends.

Snap is just for posting those "in the moment" stuff which I really don't care too much about documenting.

Anyways, that's the way I operate. Different for everyone.

I get your general point, that bits and pieces of time can't be converted directly into one's wage, since those bits and pieces can't be trivially converted into work for that same wage. But this calculation is still pretty valid under certain circumstances, at the very least as a floor: if you're not in a situation where you want more hours at work but can't get them[1], then you are in fact deciding that the marginal value of another hour of your work isn't

A couple of the caveats here are:

a) The market generally has a discrete floor on contiguous blocks of time: as a reductio ad absurdum, I generally can't sell alternating 30 seconds of work out of every minute and then add that up to 1/2 time. A related concept is that there are fixed costs associated with setting up this exchange.

b) For exempt employees, more hours of work don't translate directly into more pay, though depending on the incentive structure of the firm, they may translate stochastically (e.g. working harder to get a raise). The main point is that this relationship isn't continuous and it isn't frictionless.

That being said, it's really not a bad heuristic for trying to compare the value of time vs money. If I have a preference against spending my time on some task roughly on par with my preference for not working further, I can at the very least set a bound on what my time is worth: e.g. if I know I can reliably get software contracting work for an aftertax $120/hr (incl the time taken to secure the contracts), then it's somewhere between a heuristic and a tautology to say that I'm valuing a marginal hour of free time at >$120, which suggests that I should be willing to spend $120 on something that saves me from an hour of work that's comparably-unpleasant to doing an hour of contract work.

> It doesn't cost me $400 every time I go to bed for the night.

This is a particularly poor example, since ~8 hours is a contiguous enough block that you could get an entirely different job with a night shift, so yea, the opportunity cost is literally $400/sleep if that choice was feasible.

Wear fully covering gloves no matter what. Even in summer.

Because if you have a bad accident they can keep your hands safe.

I was knocked off my bike a few years back. Car pulled out at a junction in front of me.

I went head first into the car but put my hands out to cushion the blow.

Anyway, after the impact, i took my gloves off and the tip of one finger was hanging off. The impact had opened my fingertip and cracked the bone.

The paramedics who came to treated me told me the gloves had probably saved my hand and finger. They'd lessened the severity of the impact of my hand into the car.

The paramedics also told me the gloves had stopped the open wound getting filled the dirt and debris.

I had to have an operation to clean the wound and re-attach my fingertip. The surgeon said the process was much simpler because the wound was fairly clean due to me wearing gloves. And the risk of infection and complication should be less too due to the wound being cleaner. The finger healed without any problems (although I do have some scarring on it to this day).

If you're unlucky enough to have a biking accident you will instinctively put your hands out to shield your head and body. Make sure your hand are covered fully as it might save them.

I'll never ever ride a bike without them no matter what. Even if my hands are sweating buckets due to the summer heat. It's not worth the risk.
The title refers to this very specific bit:

It wasn't clear until now what the plan was, if they would start their own service or run their cars inside the Lyft/Uber network. The fact that they will start a new service with a new name is pretty big news, and therefore not click bait.
