At earlier this month our colleague Alex Feyerke got to introduce Local-First pioneers @couchdbApache CouchDB and @pouchdb in the @localfirstOpen Local First devroom, a space dedicated to all things sync, P2P and conflict resolution.

Check out Alex’ talk: ftp.belnet.be/mirror/FOSDEM/vi

And the great company we were in: openlocalfirst.org/#program

English speakers of the fedi. In a software with the interface in English, Reading a menu with verbs such as Save, Open, Close, Edit, Format etc., do you read them as imperative (an order: "do this") or as an infinitive (the "base form" of the verb, like "to do this")?

Are you a native speaker or have English as a second language?

@kransPeter Brett That's a real and legitimate grievance, but it's a different argument from the one we were having.

Your employer using LLM translation to cut costs on documentation for a massive Korean customer (while having the resources to do it properly) is a decision made by someone with power, to save money, at the expense of Korean users. That's worth being angry about.

But I'm an individual trying to participate in a public conversation. I can't hire a personal interpreter every time I want to respond to a post. The choice I actually face is: use available tools, or stay silent. Those aren't the same situation, and the same tool can mean very different things depending on who's holding it and why.

If anything, your example reinforces the point. The problem isn't the tool, but it's who gets to decide when it's “good enough.”

“Our work demonstrates that 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 is unreliable for the detection of illicit content: it is easy to incriminate someone by sending them false content with a hash value close to illicit content (a false positive) and to avoid detection of illicit content with minimal modifications to an image (a false negative)”

White-Box Attacks on PhotoDNA Perceptual Hash Function

𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 is a widely deployed perceptual hash function used for the detection of illicit content such as Child Sexual Abuse Material (CSAM). This paper presents the first mathematical description of 𝐴𝑙𝑙𝑒𝑔𝑒𝑑 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴, a new function which has identical outputs to that of 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 for a large database of test images. From this description, several design weaknesses are identified: the algorithm is piece-wise linear and differentiable, the hash value only depends on the sum of the RGB values of each pixel, and it is trivial to find images with hash value equal to all zeroes. The paper further demonstrates that gradient-based optimization techniques and quadratic programming can exploit the mathematical weaknesses of 𝐴𝑙𝑙𝑒𝑔𝑒𝑑 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 and 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 to produce visually appealing exact collisions and second preimages; for near-collisions and near-second-preimages the image quality can be further improved. The same techniques can be used to recover the rough shapes of an image from its hash value, disproving the claim from the designer that 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 is irreversible. Finally, it is also shown that it is easy to produce high-quality perceptually identical images with a hash value that is far from the original image allowing to avoid detection. We have implemented our attacks on a large set of varied images and we have tested them on both 𝐴𝑙𝑙𝑒𝑔𝑒𝑑 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 and 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴. Our attacks have success rates close or equal to 100% and run in seconds or minutes on a personal laptop; they present a substantial improvement over earlier work that requires hours on parallel machines and that results only in near-collisions. We believe that with additional optimization of the parameters, the image quality and/or the attack performance can be further improved. Our work demonstrates that 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 is unreliable for the detection of illicit content: it is easy to incriminate someone by sending them false content with a hash value close to illicit content (a false positive) and to avoid detection of illicit content with minimal modifications to an image (a false negative). False positives and leakage of information are particularly problematic in a Client Side Scanning (CSS) scenario as envisaged by several countries, where large hash databases would be stored on every user device and billions of images would be hashed with 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 every day. Overall, our research cast serious doubts on the suitability of 𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴for the large-scale detection of illicit content.

It looks like the ⍼ saga has finally ended!

The unicode character '⍼' was a mystery first noticed in 2022: ionathan.ch/2022/04/09/angzarr. It's in the Unicode standard as a mathematical symbol. But no one could find any examples of it having been used, and no one knew what it represented. It was like the only record of an extinct species, fossilized in the Unicode standard.

But now someone has found the document it originally came from! It represents the angle 'Azimuth', and the symbol probably comes from the path light takes through a sextant. ionathan.ch/2026/02/16/angzarr

(@johncarlosbaez might appreciate this symbol!)
