So the history is actually really well described in crpgaddicts blog. First there was wizardry (basically all rpgs both in the us and japan are descendents of wizardry, some with the mixture of ultima). bard's tale is a wizardry clon

Machine learning is the new hotness in computer graphics. It drives me insane (I don't do ML).

Np hard problems aren't that hard to solve. I'm solving one right now actually for work (graph bi-partition using simulated annealing), and it doesn't even take that long. Of course my algorithm isn't actually correct

It actually does make sense, and is an important idea in complexity theory. In general, the problem of proving an arbitrary claim in ZFC isn't computable (this is just Godel's incompleteness theorem). if you confine your claims

Nope... it depends on the language you use to write the proof. Agda proofs for instance are in R.

It's important to remember that P=NP doesn't just imply that P = NP; it implies that P = PH (the polynomial hierarchy). There are a whole series of much harder problems than NP that also are in P if P = NP. Finding proofs is alwa

In graphics, dual quaternions are used in skinning, but rarely for orientation and translation.

It's often also very local. Everyone knows who some castes are like Patels and Nayars, but how many people in north india know that vellalars are relatively high caste (but not brahman) for instance. And of course the specific relati

The Chennai sanskrit community is actually wonderful, but they can be very religious. And the fact that I'm white obviously made a difference.

I lived for quite some time in india... spice wasn't the issue. Have you ever spent time around Iyengar Brahmans of the old school?

People know people who know people... the IITs are a really small world, and a lot of the graduates end up working in american tech companies.

Sanskritists can't afford silver plates... it was the standard cheap metal everyone uses.

They don't have caste... and it's important to note caste != class. There are dirt poor brahmans and rich dalits.

Technically untouchables... but in practice white people can be very high caste indeed. I worked with a sanskritist in Chennai who was a very traditional brahman, and he did eat with me, but was extremely careful about separate food and se

While last name is the big giveaway for caste, there's another issue that effects tech workers in the us, the IITs. These are the creme de la creme of indian educational istitutions (and to be honest, the single smartest group of peop

You may be confusing "neighborhood" with the more common euphemism "community" (which can also refer in India to religion). Another common way of referring to caste euphemistically is that someone comes from a good fami

They were referring to a region, like europe! Even the name India indicates this: it's the greek pronunciation of the Iranian word Hindu, which is the Iranian pronunciation of the river Sindhu, which is the traditional western border

I think the irony is that all those weird logics turned out to not just be useful for logic... but literally actually really useful! Like people make lots of money based off of them

by bodhiandpysics1 4y ago
The irony is that "why logic" has been definitely answered... all sorts of highly technical formal logic found use in computer science!

This isn't true. First the terminology is a bit weird. Steel is an alloy of iron and carbon. This fact was not known until the 19th century! Classial "wrought iron" (whih has a carbon content under 2%) has a similiar comp

the citation here is just from the 1911 britanica, which is not a terribly reliable source! For what its worth, transparent muslin is depicted on the walls of ajunta (in the Vessantara Jataka painting in cave 17) from the sixth century, an

When dealing with unix syscalls, you actually sometimes need to pass structs that aren't fully initialized, or are initialized to zero with the exception of some fields. The quintessential example is the sigaction struct.

a lovely little factoid is that in elizabethan england, a set of clothes could easily cost more than a house (Shakespeare paid a 60 pounds for the rather large house New Place, while a very fancy set of clothes could cost hundreds of pounds

When trying to understand C, it's always useful to look at what the pdp-11 did. the pdp-11 didn't have a mod instruction; but its div instruction can be used instead. Div can only take an even numbered register as its dest. Tha

They actually use more than three now. The basic architecture is that computers are organized in "strings". Each string is doubled. If the two don't agree, the result is chucked, and the system reboots. Each of these "

I'm not sure it was a good test... Latex users do appear to be significantly faster at mathematical typing... which is obviously Latex's strong suit. What Latex is in general weaker than word at arbitrary formatting... its goal i
