DDSQL Reference Complete reference for DDSQL syntax, data types, functions, operators, and statements for querying Datadog data with SQL.

intuition I’ve developed recently (mostly based on Opus):

- answering something from model weights? still some risk of hallucination
- answering something based on info in context window? almost certainly did not hallucinate

Designing MCP tools for agents: Lessons from building Datadog's MCP server | Datadog We share lessons learned building Datadog's MCP server, from designing agent-friendly tools and managing context windows to using queries instead of raw data retrieval.

wrote up some lessons from what I’ve been doing at work: www.datadoghq.com/blog/enginee...

genuinely think that Thorsten Ball is one of the most interesting+thoughtful people writing about AI but also every now and then I get the impression his brain is being cooked on Twitter registerspill.thorstenball.com/p/joy-and-cu...

More McDonald’s to Love: The Big Arch Arrives in Canada

tried it when it was piloted here in 2024 and I was disappointed - crispy onions and sauce were both meh. hopefully better in the second coming www.mcdonalds.com/ca/en-ca/new...

GitHub - rgwood/systemctl-tui: A fast, simple TUI for interacting with systemd services and their logs A fast, simple TUI for interacting with systemd services and their logs - rgwood/systemctl-tui

yeah, I should probably have Claude add systemd timer functionality to github.com/rgwood/syste...

like, the bare minimum is that it's easy to:

1. see past runs (including their stdout/stderr)
2. run a scheduled task ad-hoc (for testing and/or recovery)
3. see/configure which user a task runs as

perhaps this is a skill issue but I've always found scheduling things to be a pain on Linux; cron has too many weird gotchas, systemd timers are better but require a lot of boilerplate, neither has a decent GUI or TUI

Greg Egan's Permutation City has been on my mind lately. Touches on a lot of "what happens when computation is scarce?" questions that feel relevant today, it's a good book!

immediately thought of several horrifying ways to solve this and realized that people will almost certainly try them out

I think so. Gonna bite me eventually but there is *so* much friction with permission approval+management

ssh is an obscure but widely-deployed command. It stands for Secure Snake Home and was made in the 90s to securely play snake online

I made a massively multiplayer backend for it with support for thousands of concurrent snake players

ssh snakes.run to join!

What is OAuth? Wherein I [try to] answer a seemingly straightforward question: "WTF is OAuth, anyhow?"

Over on dead-Twitter, @geoffreylitt.com asked the following question last week:

"I desperately need a Matt Levine style explanation of how OAuth works. What is the historical cascade of requirements that got us to this place?"

Here's my attempt at an answer: leaflet.pub/p/did:plc:3v...

the reason I know this word is that I once had to cover up a zit before a first date and then I found out that the makeup I used causes zits!

my luke warm take is that we tend to over-extrapolate the speed that things diffuse into widespread existence

I actually kind of wonder if there's just a mediumterm world where only ~10% of people actually care and deploy these tools to any useful effect, and they become a wizard class of employee

I am especially in love with all the color tools

We'd love any moves toward standardization for tool search and client flexibility w/ tool results (ex: write to disk or pipe to jq instead of sticking the whole result in context window).

(also, hi! we shared the stage at MCP Night but I didn't get a chance to introduce myself in the green room)

πŸ‘‹ I work on the official MCP server for a big observability platform. Biggest issue we face is fragmentation across clients; Claude Code+Cursor do clever things w/ large numbers of tools and large tool results but we can't assume that all clients will; constrains how we design our tool surface.

seems like their APIs are more open than most other chat platforms, was considering it for some home automation agent stuff

otherwise: no, not that I'm aware of
