lat
A tiny latency probe for TCP and TLS endpoints. One binary, no dependencies.
cliSmall tools, long notes.
Lumenbay is a one-person workshop for network experiments and the utilities that come out of them. Everything here is built to be small, boring, and easy to keep running.
Recent work
updated when there is something to say- Measured handshake latency across three CDN edges from four regions
- Rewrote the latency probe to do a single round trip instead of three
- Notes on keeping a small service observable without a metrics stack
- Moved everything to one VM; deleted far more than I added
Tools
hole
Logs the first bytes of every TLS handshake so you can see what a client really sends.
clikb
Plain-text notes with a search that works offline and never leaves the folder.
internalAbout
Everything here is written by one person, in the gaps between other work. There is no roadmap and no release schedule — pages appear when a note is finished, and tools get published once they have been useful for a few months without waking me up at night.
The site itself is a single static page served from the edge, which is more than it deserves.
