search for: h_id

...this is satisfied. How to do this in R? Without the coupling the least-squares formulation would seek coefficients a_p and b_p to minimize: sum_p(sum_p((s_id,p - a_p t_id,p + b_k)^2)). Minimization at each p is independent. With coupling, there would be an additional term: sum_id((sum_p(vp)-h_id)^2) where vp is a function of a_p t_id,p + b_k and of t_id. The functions for vp are nonlinear, but if necessary with some work it should be possible to get a linear function that is good enough. Also, not all stations have values at all pressures.

See patch 1 for rationale.

This picks up python and ocaml. Some of our languages are lacking a number of bindings (for example, lua and perl lack .extents, so I didn't have anything to copy from), and I felt less comfortable with golang and rust. But for python and ocaml, I was able to test a working implementation. Eric Blake (2): python: Implement .list_exports and friends ocaml: Implement .list_exports and

This cleans up the existing code base with regards to implicit use of errno from language bindings, then rebases the previous work in python on top of that. I'm still playing with the perl bindings, but got further after reading 'perldoc perlembed'. Eric Blake (4): plugins: Don't use bogus errno from non-C plugins plugins: Add new nbdkit_set_error() utility function python:

It's been several weeks since I posted v2 (I got distracted by improving libnbd to better test things, which in turn surfaced some major memory leak problems in nbdsh that are now fixed). Many of the patches are minor rebases from v2, with the biggest changes being fallout from: - patch 2: rename nbdkit_add_default_export to nbdkit_use_default_export - overall: this missed 1.22, so update
