Thinking About Serverless Again
There was a blog entry yesterday — "Serverless: The New Way of Thinking by Alen Komljen" — that I felt was making a good attempt to outline why you should aim at serverless but was a little incomplete. In my previous serverless post last year I talked about the fact that you're not de ...

Codex KV: Properly Generating the File
The previous post has a code sample in it that was figuratively physically painful for me to write. Avoiding the number of syscalls that are invoked, the code isn’t all too efficient as I now measure things. It uses way too much managed memory and it is subject to failures as we increase the am ...
