read more ➔SRFI 270 is now in final status. Floating-point numbers are usually stored in radix 2, but are written by users in radix 10. This SRFI introduces Scheme syntax for hexadecimal floating point constants based on C99’s syntax. They use radix 16 for writing the integer and fractional part, and a…
read more ➔SRFI 271 is now in final status.This SRFI proposes a pattern of libraries for binary input ports that produce random bytes. Libraries are divided into “randomized” and “determinized” categories to address different uses of random data. The design leaves the details of random number…
read more ➔SRFI 278 is now in draft status. This SRFI defines procedures on Scheme numbers that aim to improve the portability and usefulness of Scheme arithmetic. These procedures include predicates with extended domains, hyperbolic and inverse hyperbolic functions, the R6RS numeric tower, and…
read more ➔Hello! I’ve been working on a Django site recently, and I decided to use SQLite as the database. When I was getting started with using SQLite as database for a website I read a bunch of blog posts about how it is totally fine to use SQLite in production for a small site and I think it is totally…

read more ➔The 'Special Value' Pi 4 pictured above is probably the rarest Raspberry Pi I own—even rarer than my <lue special edition Pi. A Raspberry Pi reseller briefly listed a special 'value edition' Pi 4. But the product page 404's now. While it was up, my curiosity got the better of me, and now I have two…
read more ➔SRFI 277 is now in draft status. Cyclic ports are like infinite string and bytevector input ports: they produce the elements of a given sequence repeatedly, forever. While their intended use is as reusable seeds for SRFI 271 random ports, they are also useful whenever a…

read more ➔This is a quick post, mostly for my own reference. I've avoided LUTs and 'Log' video footage for years1, mostly because of the extra tiny bit of workflow involved. Like RAW photos, 'Log' footage retains the video sensor's full dynamic range, so you can pull more color and luminance information out…
