I've just tried out of the interest making a plot in matplotlib, (1) save it to eps and (2) save it to pdf then convert to ps. And the original .eps is pretty readable, but the ps converted from pdf has some kind of "stream"

I liked how, back in the day, when the figures for the papers were in .eps format, I could just change the line-width on the plots by just editing the file. Now they are mostly pdf which is better for the file size, but worse for tinkering,

I've found this paper interesting, as while there is a lot of discussion of number of deaths from covid-19, a common concern/theory is whether many of elderly are primarily dying from other underlying causes. This paper actually c

The law is mentioned often on HN. But the question I never see discussed: what are the specific strategies to avoid it. I.e. what comes to mind is keeping the set of metrics, and then use a randomly chosen one each year for decision making&

I think any claimed 'full self driving' car should be required to pass a driving test like regular drivers do. It's pretty clear to me that Tesla will not pass that. So question closed, it should not be on the road.

Seeing these news I was wondering if the governments have to be more cautions with these suspensions. I.e. as far as I understand there is no evidence so far that the clotting is caused by the actual vaccine. And obviously if you vaccinate

No, I don't think it is. Separately from rationalist community, there is substantial amount of work showing that Bayesian updating and reasoning is in some sense the optimal way of operating under uncertainty. It is also certainly true

(Astrophysist here). This is complete BS. (I can't comment on the theoretical aspects of gravitomagnetism, not my area of expertise) but the data part is a joke. They "fitted" the rotation curves of three galaxies with thei

As a person who mostly does (large) data analysis and mostly uses python, I've recently thought of when I prefer to use spreadsheets vs python and my (personal) conclusion was to use spreadsheets, when my data can fit into one screen.

Listening to the examples, it looks to me that these new codecs now basically do speech to text, send the text with a little bit of extra info and then TTS on the other end.

I am not an anarchist or libertarian, so I believe in democratic governements. And I do believe it's their job to establish rules/regulations/laws that benefits society as a whole. Obviously and important point is the governm

I think, yes, somebody should adjust taxes accordingly. The status quo with existing costs and taxes already effectively establishes some preferences for industries/goals, just implicitely. I think trying to explicitely express those p

I think it is probably good to tax for Co2 production as a way of addressing global warming. I just don't think we should equate bitcoin production with other CO2 producers. I.e. I personally think that the CPU-cycles used for science

My take on this is the following. Everything we do as a society I think should be from time to time evaluated from a point of view of benefits for society/world and then depending on this evaluation, the incentives should be updated to

I disagree with this claim in the article: "Not all falsifiable claims, then, are scientific, and not all scientific claims are falsifiable. How would one directly test the Big Bang Theory, which seeks to explain the origins of the uni

I think it is a fair question how to organize science for best results (maximum productivity ?). I am no fan of pressure to apply for grants, which is particularly strong in the US. Also the amount of pressure/effort needed to get perm

We've had the early data release 3 from Gaia, There are several others incoming. The distances are good up to ~ few kpc which is ~ 1% of the size of the galaxy. And it sees ~1% of stars in the Galaxy

The galaxies are not randomly distributed. In fact there are correlations between galaxy distributions at various scales that essentialy can be traced to initial perturbations that arose after the big bang. Multiple projects are now working

Diffraction spikes are different from saturation trails. The saturation goes preferentially along CCD columns/rows, while diffraction spikes are oriented like the support of the secondary mirror.

These are bright stars so they are in Tycho catalogue (which is a catalog of 2.5 million brightest stars)

by sega_sai 6y ago
Those are saturated stars. When the stars are too bright the charge tend do spread along the detector producing those lines

There are some areas where only data in one of the colors is available -- those look either blue/red or green.

What a bunch of ideological cr*p. All you need to know about this is the author puts the word science in climate science in quotation marks. Or makes a "highly reasoned" point about redistribution: "Redistribution, by definit

I'm not sure rewriting Latex in XYZ is a good idea. The whole thing is a mess and a pain to use (and I use it multiple times a week). Sure the documents often look good, but when they don't or there is an error, fixing it just bec

Is there some kind of private/public key signing technique for videos, when the camera creating a video signs it with some key providing a signature that can be verified for authenticity ? so you would be able to at least verify that t
