I use Sympy interactively, and I don't know what you mean by "forced". It doesn't feel that way to me.

You can use Maxima via Emacs with Latex output: https://www.emacswiki.org/emacs/MaximaMode

Sympy can output to Latex or unicode - either looks good.

Indent by two spaces if you want to quote some code, otherwise the asterisks get turned into italics. plot3d ([cos(x)*(3 + y*cos(x/2)), sin(x)*(3 + y*cos(x/2)), y*sin(x/2)], [x, -%pi, %pi], [y, -1, 1], ['grid, 50, 15

Integration and differentiation are opposites: Integration is well behaved numerically, but poorly behaved algebraically. Differentiation is poorly behaved numerically, but well behaved algebraically. Therefore if one wants to do "auto

You're assuming that you want to express the integral as an elementary function, or as a member of another narrow class of functions. It's only in that case that the lack of a chain rule is a problem. What you actually want is the

Integration is a computable operator ([1]), so arguably such a thing does already exist. The difficulty though is in computing it efficiently, especially in high dimensions. [1] - https://en.wikipedia.org/wiki/Computabl

The use of SHA-1 in v1 seems like a major problem. [edit] That doesn't imply that BTv2 is the right successor protocol.

If T:V->V is a linear transformation and "^" is the exterior product then T(u^v)=T(u)^T(v). For example, let T be a reflection about the plane spanned by e1 and e2. Then T(e1^e2)=e1^e2, but T(e1 x e2) = -e1 x e2, where "x&

There's interesting stuff like Conformal Geometric Algebra and Projective Geometric Algebra. The idea behind them being that geometric objects like lines, circles and points can be represented as elements of a Clifford algebra, with th

There have been attempts to use it in physics, mainly as a way of unifying the various formalisms that get used there: http://geocalc.clas.asu.edu/html/Overview.html

Regarding your analogy, Hong Kong in this analogy should be a fully grown adult by now, and should have fully autonomy as a result.

by ogogmad 6y ago
The people of Hong Kong aren't to blame for the original injustice, so why are they the ones being victimised?

by ogogmad 6y ago
Not everyone on HN is from the US, so I don't see how your point is relevant.

Hmm. Dijkstra = Nearest Node First, Bellman-Ford = Shortest k-Edge Path.

AI is still quite limited but improving at a decent pace. Look forward to more intelligent game AIs and possible auto-pilot on cars, and stuff that might seem far-fetched today.

If you become dependent on another country to produce some good, then you become vulnerable to them withdrawing that same good. Globalisation is arguably bad security. It makes sense for democracies to favour trade with other democracies, w

I don't think the article author understands either machine learning or MCTS. It's not as simple as "it plays a bunch of games against itself". Additionally, AlphaZero does not get any input from grandmaster games.

I think many Russian people, especially those who watch or read mainly Russian news, hold such views with complete sincerity. The internal propaganda is quite effective.

The attempted murder of Sergei Skripal by Russia is a conspiracy theory? Who else would poison him with a nerve agent? Who else would have the motive? Who'd have access to such an agent?
