some content like file listings

ive started https://github.com/sph-mn/sph-sc and have been using it a
lot over the years and worked through several c edge cases. i enjoy

hints and ideas on the general topic. i you have any questions, i'd be
happy to answer
surely not the ideal way to generate numbers with a normal distribution,
but there is a way to use custom probabilities from a list, which i
think is nice to know.
it works like this:

i think it is possible to restrict the bindings available for code that
is evaluated with eval-in-sandbox. eval-in-sandbox accepts a keyword
argument named #:module for supplying a module object which gives all
bindings that will be available to the evaluated code. a module with the
allowed bin

i once wrote a rfc3339 reader/writer and worked through some gotchas, maybe the

it is at /usr/share/guile/2.2/srfi/srfi-37.scm. i didnt see an option for the

apparently the --name=value syntax is to allow for long options with optional values. othe

hi. in the past year i have implemented my idea of how a basic graph

it uses a memory-mapped data store to persist bi-directionally ordered
