Previous discussion: https://news.ycombinator.com/item?id=10731023 Resubmitted because I have thought about this article often since I read it 8(!) years ago.

Also, I think the placebo effect is popularly misunderstood: https://www.dcscience.net/2015/12/11/placebo-effects-are-wea...

Yeah but it gets the whole prompt every time, right? So the whatever state it could compute for the first forward pass, it could also compute on the subsequent one. Hence, does it matter that it can’t store the state, if it can recompute it

I think the underlying question here is: "Is it better to spend lecture time learning the bag of tricks, and then the people who need more can learn theory? Or is it better to teach theory and intuition and then people who need to do i

In this technique the letters do not leave their grid box. A wide letter next to a narrow letter will at most push hard up against the edge of its box (usually there has to be white space there so that, e.g. mm doesn’t become one glyph)

Funny, just today I had a reason to run a very old piece of software, designed around punch card input: https://lss.fnal.gov/archive/nal/fermilab-nal-091.pdf The input is now textual, but you still have to write “

Parent is making a distinction between “strongly” and “statically” typed. By some definitions. Type conversions in Elixir are generally explicit (contrast with JavaScript) and the type of a variable matters at runtime (e.g think about patte

Last author can mean anything from: - I had the whole idea and held someone's hand the whole time they did the grunt work, then I wrote the whole damn paper except for making the fonts correct. to: - I am the boss. I am vaguely aware t

Many of the privacy/security/data restrictions that Apple imposes on apps are not and can not be enforced by technical means (e.g. just gating APIs behind system-level permission dialogs). They require some combination of manual r

This could be used as an argument in favour of immutability. If you effectively spin up a "new" computer every time you restart a box, then it forcibly surfaces any issues with your deployment or first-run. It's not like you

I'm mostly interested in the manufacturing technology -- seems like they're doing some kind of friction/ultrasonic/diffusion welding between the titanium frame and the aluminium insides. That's a notoriously difficu

Yup, the only word a physics professor likes more than “negligible” is “trivial”.

Hm, I think the AI does several scary things when applied to weapons: Makes countermeasures harder (can’t just jam the control signal) Allows scale (don’t need 1 pilot per drone, so can have 1000 drones flying in a swarm) And perhaps most s

Ha, yes that’s a funny line. I think what they’re getting at is that in order to reduce your core temperature, your body will move hot blood to your skin and extremities, raising their temperature (and making you feel hot!). This increases

Art made from a collage of, say, magazine photos does not supplant or substitute for the magazine photos which is why it's much more likely to be deemed fair-use. Despite the collage using perhaps large portions of the copyrighted phot

It’s a bit of a stretch but if you write your equations in sympy in a Jupyter notebook, you can display nice LaTeX renders of the expressions and then either do math with them or just evaluate them as if you’d written them as a normal pytho

So… Land covered with sludge and lichen, and a rotten-egg smelling black ocean lapping at the shores. Wonderful!

I don't quite understand the sentiment. So, let's say we have a project. For whatever technical (or social, historical, religious...) reason, C is chosen as the right language. Why does that imply that the programmers on that proj

Yeah it does. If you do: x = dd() print(x.tyypo.a.b) you'll get "DotDict()" The problem is that an object can't know whether you're getting a node that you're later going to assign a leaf to... or

More like superinductors than supercapacitors - the energy is stored in a magnetic field (inductor) and not an electric field (capacitor)

Minor nitpick — "now we can run 1 billion amps at 100V" — there is a limit to how much current you can put down a superconductor. For example I think commercial YBCO superconductor tape will do roughly 1000A/mm^2 (and even th

I agree. As a physicist, I am very comfortable with the idea that all models of reality are wrong^1, but some models are useful for some things. For example: If you want to get a rocket into space, Newton’s laws are useful (despite being “w

Because the zip file only makes the photos harder to work with and probably takes more disk space than if they were unzipped (since you fundamentally can’t compress an already compressed file).

by heisenzombie 3y ago
Why would you keep photos in a zip file? Are they uncompressed RAW or something? Anyway, you could try using something like https://bitbucket.org/agalanin/fuse-zip/src/master/ To mount the zip file and

Thanks for this, sounds right to me. It’s interesting to me that the ideal curriculum changes as a function of the resources available.
