January in MT is no joke. Were the activities in that part of the year more on the theory end? Did you have to wait long between your reservation and getting a spot?

We talk about the time-value of money; perhaps there’s also a time-value of time.

These resemble portfolio hedging bets on potential future paths of technology playforms that could affect their ad biz. Google seems to buy a spread of small bets with several-year expiry and high convexity (i.e. big payout if equilibrium

One layer of the internet is about packets, another is about ordered sequential streams — and both are widely supported protocols. Above these could potentially sit a dissemination layer, retaining and persisting anything of interest. But

This is what HN was like in the early years -- a (much) smaller community of people making things, sharing them, and rooting each other on.

A high profile example is the Donlin project in Alaska. They've been spending decades on de-risking and logistics, and once the gold becomes valuable enough to extract it's likely to be one of the largest mines in the world. htt

The lofty ask price may be unduly anchored by the hypothetical value it could have represented to Google in the scenario where something like this turned out to be the next big platform. Web and later mobile represented big shifts of econo

You know how a lot of engineering comes down to making good choices about trade offs? Could be speed vs memory, could be which language or API to use, could be keeping it simple vs anticipating likely future needs. Same thing goes for wor

Eizo sells monitors for color sensitive work which contain built in calibration probes that pop out of a hidden compartment. They can be set to recalibrate on a schedule. They are pretty neat. https://www.eizo.com/products

Did the diffuse reflection reconstruction rely on high speed photography? Or a special geometric setup of the reflector? Trying to think of how this could work.

Did you find the work to be intellectually satisfying and creative, or was it somewhat rote in the sense of having to spend lots of energy on data hygiene?

The arithmetic vs. geometric mean distinction is a good one to note. Since you mention risk-adjusted return, do you favor any particular approaches to optimization? ReSolve makes a pretty strong case for numerical optimization, summarized

You wonder what analysis went into that deal. Just the month before, Uber had announced a $5.2 billion loss for the quarter, which gives a sense of the competitive landscape SuperShuttle faced. There are also arguments that PE has been doi

US RDA is 0.8 grams/day per kg of bodyweight. For a 150 pound / 68 kg person that’s around 55 grams.

The line about the “Apple-designed rubber dome” sticks out. Why even say that? Did Apple not design the other bits? My sympathy for whomever over there is trying to navigate the whole keyboard situation and messaging.

It is the craziest thing, isn’t it, that programs are meant to be both read by humans and executed by machines which operate at significantly different time scales than us?

That’s a great point about the term “intuitive”. Our intuition is based on our own experience, so it is necessarily different for each of us. But we can at least unite around shared experience, our cultural heritage and language. User in

This graph comparing 20 year total returns suggests another reason gold is considered by some to be a worthwhile “investment”: https://twitter.com/charliebilello/status/116655914552655052...

Regarding precedent: the Bank of Japan began QE in 2001 and has expanded it beyond sovereign bonds to also buy equities and ETF’s. Could the day come when the Fed bids up $BYND?

My experience has likewise been that film DP’s have extremely impressive visual acuity, memory for color, etc. Talented artists often have developed whole sets of skills that the rest of us are unaware are even skills. In the same way a p

A price inflation measure like CPI is a summary statistic, so it does not capture the underlying dispersion of costs as various people experience them. It is true that imported, mass-manufactured goods remain cheap, such as TV’s. At the s

The basic attention token ( https://basicattentiontoken.org/ ) seems to have the right characteristics and incentives to fill this role. Any ideas why the others have failed so far? It’s hard to insert yourself as a value-a

A fun variation is pausing to floss halfway through brushing your teeth — foamy mouth and all. A major function of toothpaste is that it breaks up bacterial biofilm, so it provides a nice buff to the mechanical action of flossing.

The most interesting and least elaborated detail is the Afterburner FPGA. I’m curious what the programming model is (Metal compute kernels?) and how it compares to GPU.

There’s also no natural law that says it needs to be stationary. The historical mean can just gradually rise. It can be like climate change. This is what makes markets fascinating — many independent agents evaluating the present opport

Keep in mind that SPY yield today is 1.9% — below CPI — so you are losing value even before paying tax on that income. If you are hoping for capital gains / equity risk premium to provide extra return, you owe yourself to read a bit a

It’s almost as though you have to treat them like human drivers. We cannot formally verify 16 year olds, either, or sufficiently introspect accurate reasons for their behavior. Instead, we require them to pass a test, we apply actuarial

Makes sense; thanks. I'm out of my depth but it seems neurosurgery may just have it easier here, being able to fix a rigid stereotaxy head frame and fiducial markers across both imaging and therapy. Not to mention less tissue deforma
