One of the supercomputing centres I most like to work with is Pawsey Supercomputing in Australia.

52% of the USA's Fortune 500 companies have disappeared since the year 2000.
The current AI narrative might be a function for entropy in the market, but there's likely as many leaders treading water that would have drowned post-ZIRP, as there are "disruption" stories.
2026 will be interesting.

In our Quantum Computing community, we have no shortage of "interesting characters". Some of those have become celebrities in their own rights, like Scott Aaronson, who's blog has become a go-to destination for the inevitable "well actually" post after any overly enthusiastic press release.

It's nearly time to talk about a new project we're releasing. The best thing is it's open source, it's for the community, and it's something I know a lot of product teams in Quantum Computing will benefit from. Providing value doesn't always need to be technical or complicated. More on this soon.

Here's a look behind the scenes as I get ready for a conference in Tokyo. I've been too busy to do the (overdue) planned headshot photography session, so I wondered... could AI help me repurpose my general avatar?
Spoiler: the result in the second image is unintentionally hilarious.

I keep thinking about a comment I read. Making me think about all the various local maxima we are experiencing in our current lives, that will zoom off in new directions as progress (and entropy) rolls forward:
"Trebuchets are what you get when your Physics knowledge outpaces your Chemistry".

I read the new IonQ and Airbus white paper about #quantumcomputing for transport logistics optimisation so you don't have to... TLDR?
A new Multi-Angle Layered Variational Quantum Algorithm (MALVQA) that uses fewer two-qubit gates than standard QAOA approaches, and a novel cost function.

I got tired of juggling multiple platforms for content publishing, and I wanted to see all my content in one view. Bebop is my custom CMS built for content campaigns --> Hashnode, Dev, Bluesky, and Mastodon are working, and there's a built-in local blog too.
v0.2.3 is on Github.

Just pushed the 0.2.0 release of the open source Bebop CMS.
This version adds cross-posting to Hashnode and Dev as examples of the "Buffer for blog posts" features. Building my own tool specifically for developer advocate content posting, reposting, remote tracking, etc.

I miss the era of open APIs and developer advocacy being the norm. I lost a few hours tonight extending the Bebop CMS publishing module to include Medium. But the APIs and integration tokens are shut down, regardless of the developer site down out of date saying otherwise. My mistake 😬

A lovely bit of user experience design from the team at Clay.
The "LAST USED" is going to save a lot of wasted time when you count that up across their entire userbase.

I was testing Microsoft's CoPilot after seeing @mustafasuleymanai.bsky.social post about Think Deeper. I asked it my usual selection of questions around quantum computing calculations to see how well it can read Pauli Matrices / Bloch Spheres etc. And then this exchange happened 😂

Refer to my earlier comments that we're about to see Quantum Computing companies repositioning to align with the prevailing AI investments.
Sovereign funds have propped up the VC pullback from quantum, but there's still a shortfall to be met. Projects like Stargate create the umbrella to do that.

When making developer docs, be sure to use the brightest whitest style possible, with tiny text, and the softest shades of grey the eye can barely detect on the screen. Making them work harder to read your content makes them appreciate it more, and earns their respect as a worthy challenge.
