Anti-patterns when building container images
This is a list of recurring anti-patterns that I see when I help folks with their container build pipelines, and suggestions to avoid them or refactor them into something better.

Fast CSV Processing with SIMD
I recently learned of csvquote , a tool that encodes troublesome CSV characters such that unix tools can correctly process them. It reverses the encoding at the end of the pipeline, recovering the original input. The original implementation handles CSV quotes using the straightforward, naive method. However, there’s a…

Reflecting on Four Years at Databricks

0x7FDE623822FC16E6: A magic constant for double float reciprocal (2011)
EDIT: I never expected this post to garner so much interest. Just to be clear, using the constant is a very bad idea in almost every situation I can think of. Even instructions like RCPSS should only be used by people who are convinced that the tradeoffs are worth it (or don’t have any other choice). Subtracting from…

Lisp as an alternative to Java (2000)
It turns out my hopes were answered. First, Prechelt published another article that covers Tcl, Python, Perl, and Rexx. Also, Ron Garret (nee Erann Gat) did a follow-up study in which he asked programmers to write Prechelt's test program in Lisp. His results show that the resulting Lisp programs ran faster on average…

Clever vs. Insightful Code
“Don’t write clever code.” Why not? “Because it’s hard to understand.” People who say this think of clever code such as Duff’s Device: Duff's Device send(to, from, count) registershort*to, *from; registercount; { registern =(count +7) /8; switch(count %8) { case0: do{ *to =*from++; case7: *to =*from++; case6: *to…
