| | | | | Updated: 2023-01-06 About a year ago I was bitten by the PL bug. It started with reading Crafting Interpreters and discovering the wonders hidden under the hood of a compiler. I am also been a big fan of Emacs, and this started to get me interested in how its interpreter works. At the same time, I was reading the Rust book and trying to understand the concepts there. This all came to a head, and I decided to write an Emacs Lisp interpreter called rune in Rust. | |

| | | | | [AI summary] The text provides an in-depth exploration of SIMD (Single Instruction, Multiple Data) programming, focusing on its application in optimizing algorithms like base64 decoding. It outlines the challenges of writing portable SIMD code across different architectures, the role of compilers and instruction sets, and the importance of avoiding branches in performance-critical code. The article transitions into a practical example of implementing a SIMD version of the base64 decoding algorithm, emphasizing the use of shuffles and data reordering to efficiently process data in parallel. It also touches on the trade-offs between using intrinsics, portable SIMD libraries, and compiler optimizations, while highlighting the complexities of cross-platform deve... | |

| | | A little while ago I stumbled upon a golf challenge where you had to do run length encoding (RLE) on an arbitrary string, for example given the input string: 10+[>+>3+>7+>10+4<-]3>2+.>+.7+2.3+.2<2+.>15+.>.3+.6-.8-.2<+.<. it must be converted to: ++++++++++[>+>+++>+++++++>++++++++++<<<<-]>>>++.>+.+++++++..+++.<<++.>+++++++++++++++.>.+++.------. | ||
