Fun stuff! Also found this interesting tidbit: https://slehar.wordpress.com/2014/03/18/clifford-algebra-a-v... > Multiplication of all three basis vectors (e1^e2^e3) produces a three-dimensional volume seg

For those curious, ∇ . F is called 'interior derivative' and relates to divergence, whereas ∇ /\ F is called 'exterior derivative' and relates to curl. https://en.wikipedia.org/wiki/Geometric_ca

That's cheating. One would need to also define F, c, ε0, J, assuming ∇ is known from calculus. Which would make for 5 lines :)

Thank you kind stranger. The technical machinery makes much more sense now. But the intuition still lacks. An attempt. To map an R^2 vector into G^2 is trivial, (a,b) => a x + b y = (1, a, b, 0). The reverse is hard. s 1 + a x + b y + d

Thanks. Appreciate taking the effort to answer. What I'm trying to do is to gain an intuition of what kind of objects GA manipulates, then stash it for whenever I'll need that kind of manipulation, which, sadly, can be never. With

Ooof. This is almost useful. There is a simple mechanism to model multiplication of vectors represented using elements of an orthonormal basis. Each (multi)vector is a linear combination of terms, and each term is an ordered sequence of bas

How would a mere mortal could possibly divine equations like this? There is a method behind it. The formulas are derived from the study of relatively simple ODEs, in this example f'(x) = x.f(x) + 1 and g'(x) = x.g(x) − 1. The latt

Title. Abstract. Details. Most people will skim the title. Some will read the abstract. Few will read a specific paragraph or two of details. Yet, the writer doesn't know who's going to read what. Could be the writer himself, 6 mo

Obviously. Yet the 'FP doesn't scale for distributed systems' is too broad. MapReduce / Flume / Spark / BigQuery are distributed systems. What he probably meant is one can't use pure FP for OLTP at scale

Speculation. The FP community prizes mathematical beauty, for which symmetry is an important factor. It is simply ugly to promote one function argument (which one?) to a privileged role, even if the linguistic side of the brain screams that

The seductive power of OOP has little to do with the technical merits. As you mention data oriented programming leads to better programs. Even when using OOP technology, programs usually tend to become data oriented (hello protos), and &#x2

It depends on what the meaning of the word 'scale' is. Analytics is definitely using a ton of FP-flavored computation at gigantic scales. The #1 principle of FP is the insistence on computation with no side effects. Relational alg

This is amazing, and obvious in retrospect. Gradual compilation can be adopted, well, gradually, without breaking existing code. 100% upside, 0% downside. PyPy team should consider making this delivery mode the #1 priority. Even worth recon

Thanks, appreciated. Your example rhymes with u/jhoechtl remark that there is no standardized way to manage stack traces, aka stacked error contexts. Perhaps the Golang elves will come up with an elegant solution. By 2025 :)

Granted, explicit error handling is a good idea. At some level, it depends on the personal style. Perhaps I'm missing something, but I like to write a ton of assertions to validate code invariants. On assertion failure, which obviously

It's really a joke :) Fundamentally, the Go team made the correct choice between explicit and implicit error handling. Yet one would hope for a bit terser syntax and language supported stack traces, 11 years after launch. For a good ov

Next on the list: error handling. Which is absolutely not a problem, and works very very very well as is. Then again, one can hope that maybe by 2025 :) https://github.com/golang/go/issues/32437 https:/

You are correct, there are no diff3 conflicts, thanks again for the clarification. The problem is fundamentally ambiguous, and the argument a bit more subtle. As a rule of thumb, when two heuristics are available, pick the simplest one (e.g

Thanks for the example. History manipulation is a nono. While I'm not a git/diff3 expert, could one say 'make patch K from commit triple K0,K1,K2', meaning 'all changes between commits K1 and K2, with respect to ori
