Happy Monday 💖
Photo of a V60 that’s been brewed on top of a mug on a set of scales. Next to it is a small bag of coffee labelled “Crosby”.

Starting to feel festive 🎄🥰

All-in on the coffee theme this year. Crosby Coffee’s whole bean Advent calendar at the back and Rave’s coffee chocolate one at the front ☕️
Photo of two Advent calendars on a wooden worktop. At the back is a very large one thats decorated with a hand-drawn map featuring Liverpool landmarks. At the front is a much more normal-sized one featuring art of people at a small village/ski resort in a valley. Many are skiing, ice skating, or playing in the snow.

Haul of interesting #coffee from my Dublin trip, along with @jameshoffmann.bsky.social’s latest book that was waiting for me when I got home 💖☕️
From left to right: a bag of Tanat Ethiopia Alo (natural, mosto anaerobic fermentation), a bag of Blind Monkey Geisha Competition Lot Granja Paraíso 92 from Colombia (double anaerobic, thermal shock process), a box of DAK Yuzu Crew from Colombia (washed, cold press process), a sachet of Little Wolf Companion specialty instant coffee (a blend of washed Honduran and natural Ethiopian coffee), and the 3rd Edition of James Hoffmann’s World Atlas of Coffee. All of them are sat on a wooden worktop.

If you were at my talk – The Computer Wants to Lose Your Data – the slides are now up!

Here's the customary 1000ft view of about half of them.

I was getting some talk practice in last night and the only surface that was the right height in my hotel room was the tea & coffee cubby, so uh…

Very excited about my #SREcon talk, but also can't wait to be out of slide layout hell 😅
Screenshot of a presentation slide titled "Pages vs Sectors", which illustrates different data sizes using colourful blocks. It shows 16kB pages in memory, then SSD with 4kB sectors and an old HDD with 512b sectors.

shout out to my partner for pointing a camera at me while i was taking selfies on a hill and enabling my bullshit

#NewProfilePic
Selfie of me wearing aviator sunglasses at the top of a hill, looking out over a countryside view. Photo of me taking that selfie, taken by my partner on my proper camera. Screenshot of my Bluesky profile, showing the selfie as my profile pic and the wider photo of me taking the selfie as my banner.

sometimes a picture captures your country’s culture better than you could ever manage with words 😆
Picture of some people in the England crowd at the England vs Spain final of Euro 2025. Two of them are holding up a sign that says “Bangers & Mash > Chorizo”.

a decade since I moved here and these sights still make me feel giddy
Another photo of the Thames at night, a little further along so that the trees aren’t obscuring the south bank. St Paul’s is on the left and the OXO Tower is on the right.

google need to fuck entirely off bundling their shitty, broken llm features with functionality that has worked for years

it takes a completely deranged kpi culture to end up here
Screenshot of a modal where Google are forcing you to choose between keeping the long-standing feature that parses flight-related emails into your calendar and getting a bunch of broken LLM bullshit, or turning all of those off at the same time. A second modal, forcing you to choose between being able to make reservations in Google Maps - another long-standing feature - and accept a bunch of LLM shite, or turn the whole lot off.

Oh yeah, the print itself: a dust cover for AeroPress's filter holder (lightly modified from www.printables.com/model/363501... to add the logo).

#3DPrinting
Photo of a hexagonal prism with rounded corners, designed to cover AeroPress's filter holder. The AeroPress logo is debossed in the top. The same cover nest to the filter holder. A side view of the cover, with a bit of the 3D printer (a Prusa Core One) showing in the background. A top down view of the cover, showing the AeroPress logo.

Did my first print with scarf seams yesterday and the result is decent.

In order: most flattering lighting, least flattering, something more typical of what you’d see.

I’ve read that with a few more tweaks you can get them even less visible, so I’ll have to keep experimenting 👀

#3DPrinting #Prusa
Photo of a 3D printed object that’s a rounded hexagon with a cylinder cutout. The way it’s lit makes the seam invisible. The same object, but rotated to make the seam maximally visible. It’s still less prominent than more typical print seams. The same object again, rotated to catch the light in a way that gives you an idea of what it looks like most of the time.
