We're looking for a Project Manager to join our team on a fixed-term contract to cover maternity leave. This role is part-time with excellent benefits. Please read the full job description for more information: misc.tetralogical.com/careers/2026... The closing date is Sunday 11 January.

Draft of the next charter for the W3C Verifiable Credentials WG is now at "refinement stage" meaning that W3C members are invited to comment. w3c.github.io/vc-charter-2...

We're losing a dynamic, capable young person for entirely sensible reasons. Are you the person who could take her place? You could be *anywhere* in the world. We're good on gender equality and LGBTQ, less good on ethnic and disability diversity (not bad, just not great) www.gs1.org/about/career...

Humans are lousy ay understanding scale, as in, the difference between millions, billions and trillions. So a little light recreational coding led me to create this handy guide philarcher.org/diary/2025/m...

A (highly respected and much liked) colleague just began a post on LinkedIn: "Ein kleiner Barcode". Hasn't quite got the ring of Mozart about it but, you never know, it might catch on.

TIL: One denier equals a mass of 1 gram per 9 kilometres of length. Betcha didn't know that.

Oh my

The W3C is calling for speakers for the W3C Workshop on Smart Voice Agents, an online conference from February 25 to 27, 2026. They’re looking for contributions on voice interaction, smart devices, and related standards. Read the full details at: w3.org/2025/10/smartagents-workshop

My old job at W3C is up for grabs! www.w3.org/careers/data...

I'd say it's head and shoulders above most SF books I've read in recent years.

Independent bookshops will earn 100% of the profit from sales, and ebooks will be priced the same as they are on Amazon.

Ooh, I see a new episode of www.bbc.co.uk/sounds/brand... coming from this...

Another video from me about QR Codes with GS1 Digital Link and why treating them like just another marketing QR Code will lead to problems or failure youtu.be/2VFsVfYd6Z0

Tesco has been nominated for the Best Accessibility award at the Zeroheight Design System Awards for its Digital Design System, developed with TetraLogical's accessibility specialists. Read more and cast your vote at: awards.zeroheight.com/voting/a11y-...

I agree with every word @lewisgoodall.com says in this youtu.be/Z9VITp0x5lM although my children have asked me to return all those "Best Dad ever" fathers day cards.

Retail sites often fail blind shoppers. Could agentic AI fill the gap? Tools like Innosearch can find products, describe images, and add items to your basket. @tink.uk explores further: tetralogical.com/blog/2025/08... #Accessibility #AI #AgenticWeb #InclusiveDesign #UX #DigitalInclusion

Lots of open positions at GS1 Global Office right now at all levels. Brussels, New Jersey, hybrid, remote... are any of these you or someone you know? www.gs1.org/about/careers

This is the multiverse where my semi-automatic purchases of books by Adam Roberts as they're published crosses the manifold. I wonder whether *this* Adam Roberts' readers enjoy @adamroberts.bsky.social's work. #mustPayMoreAttentionToDetail

A minor anniversary of absolutely no significance to anyone but I've now been at GS1 longer than any other job I've done - and that seemed worth a mention philarcher.org/diary/2025/8...

I was looking forward to reading a Neal Asher novel for the first time. Having read the frontispiece, I need to wash my hands, literally and figuratively philarcher.org/diary/2025/p...

This content of this article is both fascinating (mountain collapses!) and v worrying at a time when far right politics is urging ever more fossil fuel use. It's also *brilliant* Web design, made for scrolling on your phone www.bbc.co.uk/news/resourc...

A couple of hours early but I don't want to let tomorrow's date go by unremarked. 15 years ago on 25 May 2010 there was a revolution in Web design philarcher.org/diary/2025/r...

It's been a long slog by a group of dedicated and brilliant people. Thank you. This is an important step for DIDs and VCs as a technology but more importantly for privacy-preserving data exchange with integrity www.w3.org/news/2025/th...

As a bibliophile and collector of signed first editions, I've pre-ordered the signed edition from Waterstone's. Will hope for opportunity to get a personal dedication added from my old boss too, although I rarely see him these days.

To my shame, I didn't know Linus Torvalds invented Git - I only knew his name as the inventor of Linux. This is quite an anniversay.

Smaller than I thought. Not surprising it sank, really.

Turns out, not paying Elon Musk is easy philarcher.org/diary/2025/q...

Finally got a moment to update a post about signed first editions philarcher.org/diary/2021/s.... All those links to now deleted Twitter accounts needed to be sorted. And, oh, delighted to be off to Hull in May www.visithull.org/whatson/hull... - maybe I'll be able to get some more signatures

I had reason to look up the origin of the phrase "trust but verify" earlier. It orginates from Russia: doveryai, no proveryai (доверяй, но проверяй). The phrase and its origin seem very apposite for today's situation en.wikipedia.org/wiki/Trust,_...

Conundrum. I have a ticket to see @natashapulley.bsky.social in Ely next month. But... two days before that she's doing an event with Claire North in the equidistant Chelmsford. Do I cancel Ely and go to Chelmsford or go to both? @bookishsff.bsky.social What would you do?

Been on a Zoom/Teams call with me? You've seen this picture before. Here's its story and why it's special to me philarcher.org/diary/2025/t...

Interesting stat: the GDP of New Zealand is aproximately 8 times that of Heineken, 2.5 times the size of Nestlé. #GS1GlobalForum2025

Sorry to hear this news. I had the pivilege of interviewing Tim Radford back in my radio days when he was promoting a book he'd written. www.theguardian.com/media/2025/f...

Delighted to be signed up to see @natashapulley.bsky.social at Toppings, Ely, in April www.toppingbooks.co.uk/events/ely/p.... And to have just found a special first ed of The Watchmaker of Filigree Street.

We can tell you a lot about cheese! ref.gs1.org/voc/?search=...

Comic Sans on a slide. I thought that was a sackable offence?

Competitive Excel anyone? www.bbc.co.uk/news/article...

Probably my best slide today (explaining data inheritance)

Just read an email from someone making use of the prov-o, RDF Data Cube and Data Quality vocabs in real world applications (www.w3.org/TR/vocab-dqv/). Good work has lasting value...

For the record: yes, I had a good Christmas at home with the family, thanks. I hope you had a good Christmas as well. A very Happy New Year to you too. Can we take this as read for the next 2 weeks please so I don't have to keep repeating it?

Contemplating the concept of returning to work tomorrow. Lots to do and I'm keen to get on with it but, well, not until tomorrow comes...

I'm writing a quiz for our local village. I'm really pleased with this question - but do you kow the answer?

Verifiable Credentials at GS1 will happen. Our persistent repository, ref.gs1.org, will get some dev time, Vision 2030 is a massive & exciting programme, 2D rollout going well, staff award won. After 2 weeks of travel & time with friends & colleagues, it's time to head home to the family for xmas.

Friday at the office

Boarded an internal flight in USA (MSP-EWR). Delayed by 1.5 hours due to air traffic probs so we're allowed off the plane (with all baggage). Never had this experience before. Beer secured.

Def one of the best books I've read in years. Reminiscent of, but by no means a copy of, Sagan's Contact.

Another day, another example of how we're making the transition to 2D barcodes. The QR code on this small bottle if Adnams prosecco contains the solution provider's own ID and the GTIN, conformant with GS1 Digital Link URI syntax. One day, that 1D barcode can be removed, although not yet.

The US has its Out of Office switched on while they have the first of two turkey-based festivals in as many months. Enjoy the peace.

This is good advice.
