#AutoDiscover
Do you enjoy guzzling real-time TLS certificate allocations, but don't want to use a third-party service (crt.sh, CertStream, etc.)? Drink straight from the Certificate Transparency log firehose using ctail:

$ go run github.com/hdm/ctail@latest -f -m '^autodiscover\.'

The routing misconfiguration raises an important question: What other possibly more severe errors lurk on the network?
Why has Microsoft been routing example.com traffic to a company in Japan?
Company's autodiscover caused users' test credentials to be sent outside Microsoft networks.

my 2c:
1. the LLMs will autodiscover things, but you can save both your and their time by skipping the discovery phase
2. just like a human contributor seeing the codebase for the first time, there's knowledge that it will not discover unless told (e.g. implicit runtime dependencies)

It was a great week at @chainguard.bsky.social when I found out I work with the person that wrote Crane and he pointed me at some fun registry security hints.

Here's a preview of an update I'm working on to autodiscover whiteout files in registry images

god I wish I was talking about starlark lol, it's so much hackier than that

Tldr, job has memcache. For reasons, not always exactly colocated. Client can't autodiscover. so: hardcode mapping for each instance in the config, and all new turnups have to wait for 2 full rollouts to be rollback-safe

Ich könnte mich immer wieder drüber aufregen, dass Microsoft bei Outlook einfach gültige Standards ignoriert und für Autodiscover per Default anstelle des DNS-Records natürlich erstmal die Microsoft eigenen Cloud Dienste mit EXO bevorzugt 😤

It's easier for a relay that has some seed PDSes to discover more PDSes on the network (by quite literally crawling social graph references) than it is for PDSes to autodiscover relays.

As for how to get the seed PDS, I think word of mouth is the easiest method right now, although it has drawbacks.

Added! As an aside, I added my Threads account too and it doesn’t autodiscover the favicon and shorted to the username like Instagram or Bluesky. Just thought I’d mention it.

I use:

- Feedbin
- Readwise Reader

They can both autodiscover RSS from a URL + they can both also subscribe to newsletters which is useful when a site only has a newsletter, not an RSS feed

I’m also trying out Tapestry by @iconfactory.bsky.social for some high frequency feeds

🚨 Darknet Market Moves to Clearnet 🚨

A #Darknet marketplace has shifted operations to the #Clearnet, offering illicit goods. The site shares its IP with 600+ domains, some using typosquatting & recognizable brand names, such as autodiscover, snapchat, or bitcoin ! 🔒💻

maybe a brainfart?

a UX metaphor based around 'autodiscovery'.

got the idea from reticulum. quite often in configs you just need the hostname and the hash, it will just autodiscover which ports through which it can route traffic.

maybe combine this with a non-hierarchical filesystem, and i […]
