When Microsoft 365 Copilot (M365 Copilot) was asked to summarize a specially crafted Microsoft Office document, an indirect prompt injection payload triggered the execution of arbitrary instructions to fetch sensitive tenant data, such as “recent emails” and hex encode the fetched output. M365 Copilot then generated a…
Celebrating a little bit of legacy from Placemark and a new product for hydraulic simulation
A new study co-authored by a University of Wisconsin–Madison professor finds that life expectancy gains made by high-income countries in the first half of the 20th century have slowed significantly, and that none of the generations born after 1939 will reach 100 years of age on average. Published in the journal…
Having a home server and a few smart plugs leads to interesting data points like this one. Well, interesting to me, at least.
I find myself telling people that they will have to pry org-mode from my cold dead hands. Which befuddles me. Why, as an ingrate software nerd who has soured on software technology — talk about biting the hand that feeds — do I evince such strong sentiment about a software program?!
Cloudflare launched 15 years ago this week. We like to celebrate our birthday by launching new products that give back to the Internet, which will do a lot of this week. But on this occasion we've also been thinking a lot about what's changed on the Internet and what has not.
LLMs think WEIRD - Western, Educated, Industrialised, Rich, Democratic. STRAT7 explores what AI cultural bias means for researchers working across global markets.
Wait, wasn't this solved by the Romans? Anyway, my grandma ate lead paint and she was totally fine.
How Jujutsu's flexibility and safety changed my approach to version control.
Introducing kv, a statically allocated key/value server.
Today we turned off our Online Certificate Status Protocol (OCSP) service, as announced in December of last year. We stopped including OCSP URLs in our certificates more than 90 days ago, so all Let’s Encrypt certificates that contained OCSP URLs have now expired. Going forward, we will publish revocation information…
Through an analysis of 10 months of nationwide searches on Flock Safety's servers, we discovered that more than 50 federal, state, and local agencies ran hundreds of searches through Flock's national network of surveillance data in connection with protest activity. In some cases, law enforcement specifically targeted…
I didn’t invent categories to study functors; I invented them to study natural transformations. — Saunders Mac Lane
ICU gets Unicode right and pays for it. This post shows a different approach: fold-safe windows, SIMD probes, and verifiers for fast UTF‑8 search.
I just think it's neat!
We're open sourcing our programmatic low-level container runtime, Styrolite
Exploring a peculiar bit-twiddling hack at the intersection of 1980s geek sensibilities.
Note to the impatient: You can just scroll down to the drawings of fitted sheets being folded. You won’t hurt my feelings. (I’ll never even know.) But you may want to bookmark this page for later instead. You can get fast at folding fitted sheets. But to learn how to fold fitted sheets is going to take some patience…
The third edition of Automate the Boring Stuff with Python is now available for purchase or to read for free online . It has updated content and several new chapters, but one chapter that was left on the cutting room floor was "Working with Audio, Video, and Webcams" . I present the 26-page rough draft chapter in this…

Welcome to LTT Labs - your go-to destination for all things tech. Explore comprehensive test results, insightful commentary, and the latest analysis in hardware.
I got into programming because it let me turn thought into reality. If I could reason precisely, then a computer could carry out my thoughts unerringly. I could step away from tiring, ambiguous human interaction for a while.
It's been a quiet year at geminiprotocol.net thus far. I've let two "Apollo days" slip by without a word. I'm about as disappointed in myself for this as I expect many folks are unsurprised by it. I do still have plans and clear ideas for finalising the minor oustanding spec issues. I'd tell people to look forward to…
Applying human ergonomics and design principles to syntax highlighting
A problem I experienced when pursuing my PhD and submitting academic articles was that I had built solutions to problems that required dramatic scale to be effective and worthwhile. Responses to my publication submissions often claimed such problems did not exist; however, I had observed them during my time within…
