There’s a certain satisfaction in returning to an abandoned idea and realising it wasn’t wrong, just premature. Of all the reasons for an idea to not work out, "too soon" is the best.

There’s a moment in every rewrite where you realise you’re not improving the work; you’re just re-arguing with your past self. At that point you need to just step back, re-read old notes, and settle on decisions quickly to avoid getting bogged down. Often it's better to just make progress.

I just realised that I've been actively blogging (with varying definitions of actively) for more than 23 years. Over that time I published 216,972 words, 1,400,237 keystrokes, and spent (by a rough calculation) 43,394 minutes writing. Hopefully that's been time well invested!

Often, security work is 80% archaeology - digging through layers of past decisions, half-documented assumptions, and old mistakes disguised as design choices. Documentation is critical for understanding, institutional knowledge is vital for insight, and one must have the tenacity to dig for clarity.

Given the shifting ownership of US news orgs, I keep wondering if there's a viable option for an alternative that can compete effectively. There are certainly a number of non-profits, but most have a local focus and rather small staff. If there's a time to invest in independent journalism, it's now.

The thing I miss most about early forums: people actually wrote paragraphs. Today, if you see actual paragraphs, you have to wonder if it's just AI. Attention spans have shrunk from long and complex discourse which could run into several thousand words, to single sentences.

It looks like FedEx and UPS are grounding MD-11s at Boeing's recommendation following the UPS-2976 crash. I really wonder if they are going to find pylon damage on the grounded planes (similar to AA-191). www.npr.org/2025/11/08/g...
UPS and FedEx grounding MD-11 planes following deadly Kentucky crash
UPS and FedEx will ground their fleets of McDonnell Douglas MD-11 planes "out of an abundance of caution" following a deadly crash at the UPS global aviation hub in Kentucky.

Lately, I’ve been thinking about empathy - how easily it’s dismissed as weakness by those who mistake cruelty for strength. When someone mocks empathy, what they’re really rejecting is accountability for the harm they cause.

I had been busy watching the incredible US election results tonight, and missed that Isaacman was re-nominated as NASA administrator. As someone that cares deeply about space and science in general, this really does seem to be the least-bad option for NASA's future. techcrunch.com/2025/11/04/t...

The reversal comes after weeks of pressure from people like Elon Musk, who accused Transportation Secretary Sean Duffy of being ill-equipped for the job.

It’s strange how artefacts of your professional life - old emails, commits, photos - become personal archaeology. It's also strange what you can learn about yourself when you look at these things objectively.

I found some old thumb drives, and I'm a bit too nervous to plug them in to see what they are - as they may be old BadUSB test/demo devices. Most of those were fairly harmless and focused on hiding data, but a few were rather nasty (attacking the root USB controller).

Talk about a blast from the past - I just logged into my first Gmail account from shortly after the service launched back in 2004. The first email is from a ticket I opened with Gmail support, suggesting that they add POP3 support.

Is it just me, or is (non-political) conversation a dying thing across social media? I'm seeing fewer and fewer replies to non-political posts both here and on Mastodon (my posts and those I follow). It's not dead, buy it seems to be dying.

I don't do a lot of true street photography, as I mostly avoid making people the center of most of my work, but this is my favourite of all the street photos I've taken. The contrast is just so striking between these two having a friendly chat.

The more I build on DigitalOcean, the more I'm glad I went with them over other/larger players. Everything just works. Their control panel is clean and intuitive, everything is easy to find because it's exactly where it should be. The performance is really good. I'm just so happy with that decision.

There's something special about that moment in building a new product when you push the first real easter egg to production. Now comes the important question: will anyone find it before I forget about adding it.
