This cyber halloween season is the best one ever 🎃👻
If no major piece of infrastructure gets hacked or otherwise falls over today then @thsottiaux owes us a reset, that's the rules, right?
Back in the middle ages, when I was DevReling at @CircleCI in a past life, some 5 years ago, I used to do conference talks, webinars, and workshops on speeding up and optimizing CI/CD pipelines, and squeezing the most performance out of tools.
I gave my top 10-ish tips to Claude a couple of weeks ago and it got my times down by more than 50%.
Thing is, I'm more than certain it could have done it without me actually telling it what to look at, if I just grunted something like "make ci fast brrr".
I honestly don't know how to feel about it, I console myself with the fact that it has probably trained on some of my old content, so I _am_ using old Zan DevOps wisdom. 😅
My main branch's full deployment pipeline durations, each line is 5 mins, got them from skirting 15 min runtimes down to a cool 6 mins.
The NCSC is encouraging UK organisations to prepare for immediate updating of systems using PHP. Where immediate remediation is not feasible, organisations should consider taking the system offline until it can be fully mitigated.

Hey @waitrose what’s going on today?
Paid for a morning 1hr delivery slot today, the guy arrived after the window, missing 2 crates.
You charged me full price and no answer to my CS query that I opened immediately after he left.
You were supposed to be the good supermarket and now I’m srsly considering switching to ocado for my weeklies.
Odlično bi bilo če slovenska gospodarstvu in podjetništvu naklonjena vlada porine v to smer! @JJansaSDS

When building gets this fast, the bottleneck becomes judgment.
We're expanding Confidence to connect the signals behind good product decisions, from analytics to customer conversations, and keep you in control of every call.

Every team at Spotify works in a loop of building, testing, and learning.
Confidence has powered the testing part for over a decade.
Now we're expanding it so every experiment, session, and customer conversation helps shape the next decision.

Sometimes when dealing with "agentic" tools that have their AI agents only accessible via their own web interface, I feel like a human router
You: I want to do something. Claude, connect to tool A's MCP.
Claude: I'm afraid I can't do that Dave, tool A doesn't expose an MCP server.
Y: Alright, use their API then, we'll do it the old way.
C: I'm afraid I can't do that Dave, tool A doesn't expose an API.
Y: Tool A's Agent, how the heck do I tell my Claude to talk to you? There's no API, no MCP, no nothing.
A: You are absolutely right. You don't. You can tell me to do it and I'll change it for you.
Y: Yo Claude, write me a prompt for this idiot, and paste it in.
C: Most certainly good sir, here you go.
Y: Yo Agent A - do this: [pasted 374 lines]
A: Whirring.... Done.
Y: I think I've just been meat proxied.
Being a Slovene customer facing person in tech in Q4 2026 mean you can't be sure what language to greet people with .si domains anymore.

AI eng pattern of the month: Chief of Staff
Start a session that commands all your other sessions, spinning them up and tearing them down as needed, and sending messages to sessions.
I've just today realised that our very own #Xirp by @SpotifyEng can do it and it's impressive. No need for your own
Just keep your backlogs tidy and tokens can burn for as long as Tibo keeps resetting them. 🔥🔥🔥
Cooking something new to make @potniq_com fully agentic.
Not quite there yet but this is the direction I’m taking it.
