have you ever bent light with your fingertips?

pinch your thumb & forefinger together, do the same on the other hand, bring them together, where all four digits touch there’s a tiny hole

bring your hands up to your eyes, and make the hole as small as you can & things far away will now be in focus

congratulations: you have diffracted light using only your hands

I don’t know if any time of my life has blurred together more than the last four years

My talk from last week’s Observability Day is up:
“How Prometheus Halved Its Memory Usage.”
It’s a thrill ride.

The Forbes 30 doing 30-to-life now includes SBF and Elizabeth Holmes.

I’m on my way to Chicago to give a talk about Prometheus and memory usage. See you there!

the HTTP2 rapid reset issue reveals that Go has it's own dependency hell... google.golang.org/grpc declares which version of golang.org/x/net it's using, and so it's not just "update golang.org/x/net" in your application and you're safe, it's also "update GRPC in your application"... and of course this is now "update every module that uses GRPC and refers to an older version" which is now a huge sprawling mess of modules.

it's all fine saying that Go is always backwards compatible and doesn't require older versions to have updated, etc... but the reality of it is that security issues kick you in the teeth hard and the cascade of dependencies require you to update virtually everything anyway. it would be better to embrace "update everything all the time" then to have an illusion of "you only need to update your thing and not worry about other things" as the latter means you have no muscle memory or build tooling ready when you actually need to update all the things.

I like Go a lot, but I don't find the dependency / updates / supportability philosophy that they've taken on to be internally consistent or truly viable long-term, I've always held that they're smarter than I and implicitly this means I'm probably wrong, but as time passes I'm not so sure I'm wrong (I am sure they're smarter than I am though).

yes, i'm proud of this. #computeing #linux

@codinghorror I’ll be going as sexy tech debt this year

‘If your solution to some problem relies on “If everyone would just…” then you do not have a solution. Everyone is not going to just. At no time in the history of the universe has everyone just, and they’re not going to start now.’

Today was ... interesting. If you followed me for the past months over on the shitbird site, you might have seen a bunch of angry German words, lots of graphs, and the occassional news paper, radio, or TV snippet with yours truely. Let me explain.

In Austria, inflation is way above the EU average. There's no end in sight. This is especially true for basic needs like energy and food.

Our government stated in May that they'd build a food price database together with the big grocery chains. But..

OMG this thread is wild!

Dear #computing #history #datahoard bubble:

I am looking for the original advertisement of either Google Docs or potentially Google Chromebooks, strongly believing it's the former.

It was an ad in which someone wrote some words while walking counterclockwise through an office setup, destroying several laptops and showing that the written words had already been synced to the next device about to be used and destroyed.

Edit 2: thanks @HeNeArXn https://www.youtube.com/watch?v=lm-Vnx58UYo !

Grafana Pyroscope just hit 1.0 https://github.com/grafana/pyroscope/releases/tag/v1.0.0

This is open source (AGPL) Continuous Profiling, the fourth pillar of observability. It is stable, performant, and capable of running at scale.

You can also try profiling on Grafana Cloud as we provide it as a SaaS if you don't want to run your own: https://grafana.com/products/cloud/profiles-for-continuous-profiling/ you can try it for free (and if usage is small it's free forever).
