Translating promql grafana queries into otel clickhouse queries... Claude generated some interesting results. Helps with the basic query stuff, but as always gotta tweak it. Still somewhat of a timesaver from writing it ALL by scratch (though many were ALREADY copy/paste). Still required work

ALSO huge thanks @cloudflare.social for DNS & Domain management. Makes running a lab SO MUCH easier/cleaner WITHOUT breaking the bank!

OK lab is all on clickhouse (I still do SOME Prometheus just to be able to run random queries). Got logs (which... dear lord are painful IMHO in Grafana right now), metrics, traces, next... EVENTS (aka wide cardinality data). Even added ILO health checks w/ alerts!

When did "Hoax" change to "I lied my arse off and you shouldn't know about it"?

I've already shoved 125 MILLION rows into my @opentelemetry.io github.com/jasonmcintos... (using a simple clickhouse server)... :) In 16 hours... I'm probably doing a bit much in my lab... given I THINK I just crashed my k8s nodes...

Moving from prometheus to clickhouse on my lab. Can't easily capture "this change event" in obs1.0 NEED DATA, not "metrics". But... grafana: I can do it but it sucks UI, config wise, searching, etc. without a LOT of work. Go with @honeycomb.io or NewRelic or some other vendor for prod.

Just a few new #spinnaker enhancements in play... an API to finally allow killing "zombie" pipelines! Number of tickets had to answer "can you go kill this" oy!

Bought a new #toyota #Sienna. The van is solid to drive, the MPG is great, but DEAR GOD the "Tech". Rear entertainment: Miracast/HDMI ONLY (Kodi Pi box FTW). Doesn't persist keeping rear entertainment on on restart. Cruise have to turn on every start (e.g. Ford). Lot of little annoyances :(

Does anyone have a good family MDM/SSO solution? With 4 kids+wife, tablets, phones, laptops... there's a LOT of devices and the commercial offerings are PRICY. I could run OpenLDAP for mac logins, but mobile is a challenge to manage. There's a few paid but 500+year is insane to me...

I recall in the past adding load testing to be integrated into our deployments. We'd run load tests against a single "pod" to verify that it didn't break on recent changes. This caught several failures that unit/tests didn't - and not something I hear of teams doing :(. USEFUL tool for CD flows!

One of the most frustrating tactics I've seen from sales? Random posts in slacks advertising themselves with NO relation or even relevance to the slack community they're posting in. JUST saw this from a company and IMHO it's SPAMMING. AND more likely to piss me off than cold calls.

My favorite key to hit as a developer is the delete key. Deleting unused or dead code. Old dependencies no longer in use. It’s one of the most critical things to do and not done near enough

New apple touch keyboard. Like the keys - good crisp feel on button press. HATE that the function is on the bottom left - so used to that being my control key spot ... overall... worth maybe the adjustment. Definitely not a fan of the positioning though.

Super simple "5" rule I TRY to follow for "clean" microservices: Ideally than 500 lines per class. Less than 5 parameters to any method/class. No more than 5 APIs (this one in particular is a fun debate). The FUN part? This RARELY ever happens - question is WHY

I love #gradle. You can write code to define tasks and the range & support of tasks is AMAZING. BUT bad gradle can REALLY screw up your builds. Multi-module, subproject build projects have some CRAZY quirks. Many good plugins don't get well maintained. At times.. reminds me of Jenkins plugin hell

Years ago a guy said "avoid companies with dividends. They should use that money to expand the business". While not entirely "correct", AI is similar - it's enhancement. IF you let developers go because AI is so much better... why AREN'T you using those developers to improve the business?

Storage in k8s is still one of the more problem areas IMHO. Replication & failover. Playing with a NAS & looking at NFS. I'd been using Ceph/Rook but ... have hit odd falures at times. I recall gluster long ago as a hopeful to solve distributed clustering. Still feels like a rough area...

Observability memory from years ago: (@charity.wtf might enjoy this). Teams spent hours debugging a perf issue. DBAs: it's not the database! I was able to ask observability tool I was demoing: "What's query perf by region and what cause" - missing index in ONE region. Company bought the tool.

Observability memories: Was remembering early 2000's, server room. I got paged "Server room is 100 degrees". Driving in and opening up doors, blowing fans, etc. Because buttery/bug got into the AC system & fried the electronics. First real "bug" in the system. Thank god for monitoring!

It *does* take time for a team to gel. Yes. If you care about high performing teams, you should carefully weigh the costs of shuffling people around vs the hoped-for gains.
According to Tuckman's theory of group development, these stages are called,
* forming
* storming
* norming
* performing

What’s your take on this: it takes time for a team to gel. So it’s kind of criminal the way companies use often break up teams without a second thought.
