Looks very cool, congrats on the launch!

From The Information interview: You can tell what the pool of potential startup founders looks like. There's a bunch of ways you can do it. You can go on Google and search for audi…

I think journalists are snakes in general, but I don't see PG's argument that his statement is not sexist. His expanded argument seems to be: 1. A hacker ethos from a decade of pro…

Reading their actual paper further, it seems I read a bit too much into the original article. However, as their paper mentions: > The parameter space of C-2U has over one thousand …

Basically nobody was using automated gradient descent / etc because of the proclivity of these algorithms to get stuck on a boundary. The problem is the boundaries are not well def…

This is actually a really exciting development to me. (Note, what is exciting is the "optometrist algorithm" from the paper [1] not necessarily googles involvement as pitched in th…

The most interesting thing for these is liquid lithium metal--especially a great solution on diverter. For the wall neutron flux this is unfortunately seen as a "materials issue" (…

Overall this is presenting a smaller university-class tokamak with advanced superconductors to try to reach Q>2 (scientific breakeven). One of the big advantages of higher fields i…

More descriptive is Tokamak rather than ITER, since ITER is still going to have burning DT plasma in 2035 (at the earliest, according to article).

ARC is not designed to be cheaper or faster to build than ITER. Its purpose is closer to that of DEMO (engineering breakeven). ITER data will be critical for verifying the ARC desi…

The other efforts you mention are much further from having Q>1 (energy producing) fusion. FRCs and focus have not even reached Q=0.000001 and have little theoretical basis for bein…

We used graphcool for our latest launch and it probably saved hundreds of back end dev hours. The team is really responsive on slack and intercom, the interface is great and really…

We’re a small team of food lovers changing the way people eat. We built the first home sous vide immersion circulator, the first wifi connected sous vide machine, and the largest s…

There's a really great interactive nuclear energy cost calculator produced by Bulletin of the Atomic Scientists: http://thebulletin.org/nuclear-fuel-cycle-cost-calculator

Nomiku YCW15 made this.
