Fluent-bit rocks

A short survey of log collection options and why you picked the wrong one. 😜

Who am I? Where am I from?

I'm Steve Coffman and I work at Ithaka. We do JStor (academic journals) and other stuff. How big is it?

Anti-hype LLM reading list

Goals: Add links that are reasonable and good explanations of how stuff works. No hype and no vendor content if possible. Practical first-hand accounts and experience preferred (super rare at this point).

My own notes from a few months back.

Background

• Survey of LLMS
• Self-attention and transformer networks

; FIXME: The grammar has been transformed so that `w` appears after a
; token, but there is no way in ABNF to define it as token-separator
; that can optionally contain a mix of comments and white-space. Take
; `;;` as an example, for that to match `sql-stmt-list` `w` would
; have to match the empty string. But if `w` matches the empty string
; then `ISNOT` is the same as `IS NOT`.

sql-stmt-list = [ sql-stmt ] *( ";" w [ sql-stmt ] )
sql-stmt = [ "EXPLAIN" w [ "QUERY" w "PLAN" w ] ] ( alter-table-stmt / analyze-stmt / attach-stmt / begin-stmt / commit-stmt / create-index-stmt / create-table-stmt / create-trigger-stmt / create-view-stmt / create-virtual-table-stmt / delete-stmt / delete-stmt-limited / detach-stmt / drop-index-stmt / drop-table-stmt / drop-trigger-stmt / drop-view-stmt / insert-stmt / pragma-stmt / reindex-stmt / release-stmt / rollback-stmt / savepoint-stmt / select-stmt / update-stmt / update-stmt-limited / vacuum-stmt )
