On a related note, I can recommend Stanley J. Farlow's "Partial Differential Equations for Scientists and Engineers", which I bought around 2004 to better understand a fluid simulation paper I was trying to implement. (My Mat

This article reminded me of the concept or an airborne turbine [0]. Interesting to think what would happen if we had thousands or more of these immersed in jetstream somewhere, siphoning terawatts. Environmental impact could be noticeable (

Actually, the prediction accuracy here is more like "may go off any time". Likewise, for Betelgeuse (the brightest star of Orion), which would also be visible in daylight.

Love both of these. Perhaps more so "A Deepness in the Sky", with its darker tone, very thoughtful programming-related remarks, and the reversed "alien invasion" concept.

I'd love to see also a mouse-rotatable 3D model of this.

If anyone's interested in other unusual (i.e. other than an optical imaging telescope) detectors, have a look at Imaging Atmospheric Cherenkov Telescopes [0]. More details can be found e.g. in [1]. TL;DR: how to detect a very high-ener

Let's not forget that before fully-programmable shaders in NV20, NVidia had register combiners [0] in GeForce 256 (NV10), allowing more flexible texture application & blending compared to the older (sequential) pipeline. [0] http:

In Charles Stross's "Accelerando" (strongly recommended!) astronomers suspect that the inhabitants of Andromeda Galaxy converted all its baryonic matter to computronium (here: configuration of matter capable of the most effic

Right, but adaptive refinement is bread and butter of today's physics simulations. I imagine that in order to simulate our Universe, you'd go down to elementary particle level only when some of the simulated folks run their accele

An interesting challenge: build a small tree/pole-climbing robot that would methodically pollinate all flowers (manipulators, image recognition).

Same here! IIRC for me it's due to Duke Nukem 3D's default settings. (Annoying when games "forget" to respect this option, e.g. Crysis 3 in the VTOL flying segment.)

I also started with QBasic (in 1994 I think). I fondly remember its convenient graphics API (including setting the modes and palette).

There is a scene in Peter F. Hamilton's SF novel "Fallen Dragon" which immediately made me remember the restaurant "joke" from "Portnoy's Complaint". SPOILER Only here, the protagonist vomits violentl

The laptop looks nice enough, but the lack of dedicated PgUp/PgDown/Home/End keys is a deal-breaker to me. I'm also on a 13.3" (Lenovo E31-70, previously a HP ProBook) and fitting these keys really isn't a prob

Well, the details are quite pronounced and 3D also when viewed from Earth through even a smallish (~100 mm) telescope (preferably near the lunar terminator, where the Sun angle is small). Larger apertures are even better, e.g.: https:&#x2F

I'd also mention P. F. Hamilton's "Fallen Dragon", where FTL travel is possible, colonization of a few nearby Earth-like planets has happened... but it's not economically viable after all, which leads to some twiste

I ran Fedora on a ProBook 4320s (Intel GPU) in 2011-2015, no problems. The only inconvenience was the WiFi/BT adapter (Ralink, I think), which had out-of-tree drivers; I had to rebuild the interface after kernel updates. But a year or

I realized some time ago that my hobby - solar imaging - is actually a lot like fishing. You hang out on the forums, buy all the mysterious gear, then on a sunny day (with good "astronomical seeing") you set up in the field and r

I went with Vista in 2008 (having 4 GiB RAM) and never had a reason to complain; in my case, everything from drivers to games just worked. I liked the Aero and UAC. After a few years I permanently switched to Linux, but kept using Vista for

Ah, brings back fond memories. I always loved physics simulations and managed to implement a fluid solver (after reading [1]) back in 2005. When I got the basic 2D version working, I spent maybe 20 minutes just stirring the vortices with a

The same goes for South California mountains, especially if you're into solar imaging (the Big Bear Solar Observatory is there for a reason).

As for choosing random 3D directions with various distributions (and more), the Global Illumination Compendium [1] has a lot of useful formulas. [1] https://people.cs.kuleuven.be/~philip.dutre/GI/

I settled on the 13.3" form factor 6 years ago, but the lack of all dedicated PgUp, PgDown, Home, End, Ins, Del keys puts me off (I'm very used to copy/paste with Ctrl/Shift-Ins and whole line selection). Well, I'm

English is my second language. I'd say it's due to the fact that when you learn a language in school, by listening AND writing, it'll stick in your head visually. I never mistake its/it's, they're/their et

I'm an Eclipse guy and when writing this [1] for fun, debugging in Eclipse worked fine (I'm on Fedora). Code completion via Racer mostly works (except some cases like recognizing the type of the try! macro's result). [1] htt
