why are they sharing this
Goshawk Trades@GoshawkTrades

Jane Street's head of technology just explained the full spectrum of how fast their trading decisions are made. the fastest systems turn around a packet in under 100 nanoseconds. at that speed, if you attached an oscilloscope to the wire going in and the wire going out, you'd see the response start to leave before the incoming packet has finished arriving. at that speed, you can't use a CPU. you can't use any programming language. you're on an FPGA direct wired to the network. and the decisions you're making are incredibly simple. because you literally can't compute anything complex in that time. but here's the part most people miss: that's just one end of the spectrum. Jane Street runs an ensemble of systems operating at every timescale simultaneously. some decisions happen in nanoseconds. some in microseconds. some in milliseconds. some take hours or a full day. "the right way to build an optimal trading strategy is an ensemble approach. for some decisions you're making very simple decisions very quickly. for others, you're operating at the scale of microseconds, milliseconds. and in some cases, if you can get that decision turned around in an hour, that's totally fine." the faster you need to respond, the simpler the decision has to be. the slower you can afford to go, the smarter the model can be. this is why "Jane Street is just a speed game" is wrong. speed is one dimension. intelligence is the other.

@JacintaAllanMP i fear Australia can only justify this if it taxes natural resource extraction like gas and coal with an export levy of say 5%. if you so desperately want a utopia (as you should), you must implement both

trying to genuinely understand this bc this feels...impossible in his lifetime? $7.5T is crazy, but okay, doable. but 1 MILLION people on Mars?? Yea I believe we will get there eventually, but Elon is 54yrs old Either he thinks he's gonna live to 200 or we'll do this in ~30yrs?

SITUATION DETECTED: SpaceX has approved a new compensation package for Elon Musk ahead of its IPO. 200M super-voting shares if SpaceX hits a valuation of $7.5T and establishes a Mars colony of 1M people. He gets nothing if they miss targets.

people who pick red on the blue/red button reframe it as “do you want to live.” but the framing is the content. make blue huge clear font, red in tiny eye-chart font only some can read … red stops being rational self-interest and becomes killing people who couldn’t see the choice

The literal only result of picking blue is that you increase your own chance of death from 0% to not 0%. There are only 2 reasons to pick blue: you are stupid or you are suicidal. There is only one reason to try to convince others to pick blue: you want them to die. If you don’t understand this I actually think you are not a human being

Everyone in the world has to take a private vote by pressing a red or blue button. If more than 50% of people press the blue button, everyone survives. If less than 50% of people press the blue button, only people who pressed the red button survive. Which button would you press?

Red looks selfish until you realize: if everyone presses red, everyone lives. The "cooperative" answer requires coordination and trust. The "selfish" answer just requires everyone making the same selfish choice.

Only one chance in this lifetime… Like watching sunset at the beach from the most foreign seat in the cosmos, I couldn’t resist a cell phone video of Earthset. You can hear the shutter on the Nikon as @Astro_Christina is hammering away on 3-shot brackets and capturing those exceptional Earthset photos through the 400mm lens. @AstroVicGlover was in window 3 watching with @Astro_Jeremy next to him. I could barely see the Moon through the docking hatch window but the iPhone was the perfect size to catch the view…this is uncropped, uncut with 8x zoom which is quite comparable to the view of the human eye. Enjoy.

Sydney is one of the great cities. People seem at ease, free, healthy, attractive, confident, open. There’s a freshness & energy which has gone missing in Europe & the US. It’s what America thinks it is but isn’t any longer.
