"Websites have a new way to spy on visitors: Analyzing their SSD activity"
https://arstechnica.com/security/2026/05/websites-have-a-new-way-to-spy-on-visitors-analyzing-their-ssd-activity/Writing 1 gigabyte of data via browser"s javascript to a SSD to fingerprint users? Meh.
"Unlike previous contention side-channel attacks on SSDs, FROST runs exclusively in the browser. It uses JavaScript that interacts with the OPFS (origin private file system), an allocated storage space that’s reserved for a specific site to run code needed to complete a given task. Websites can create one with no interaction required by the visitor." #frost #websec #fingerprint #Security #opfs

Who here knows enough #webplatfrom and #webapi to know if relative links exists with the Origin Private File System (#OPFS)?
thanks much for RT and dig to find people knowing...

The #wasm build of #sqlite opens up great new possibilities in the #browser, especially when coupled with the Origin Private File System (#opfs). I've used it to implement importing huge #csv or #jsonl #datasets right in the browser. Import, validate, search, edit, close the browser and continue tomorrow, stream the database (with on-the-fly compression!) to the server when ready – it's all possible!
Another interesting use case I came across today: use it in #golang to get rid of #cgo!

I’ll be in Milan, Italy 🇮🇹 for #Codemotion tomorrow and (half of) the day after to talk about #SQLite, #WebAssembly (#Wasm), and the Origin Private File System (#OPFS). My talk is tomorrow, 16:30 🕟: https://conferences.codemotion.com/milan2023-live/agenda/. If you’re at the conference, be sure to say “ciao” 🤌!

📢 The Origin Private File System (OPFS) is a cross-browser solution for your performance-critical, file-based storage needs on the Web! @chrisdavidmills has documented everything you need to know about the API over on MDN: https://developer.mozilla.org/en-US/docs/Web/API/File_System_API/Origin_private_file_system.
💡 This is what powers Photoshop (https://developer.chrome.com/blog/how-photoshop-solved-working-with-files-larger-than-can-fit-into-memory/) and SQLite Wasm (https://developer.chrome.com/blog/sqlite-wasm-in-the-browser-backed-by-the-origin-private-file-system/).

#Link | Understanding OPFS
Storage in web apps can be a real pain, but nearly every year the possibilities expand. Thomas Steiner (@tomayac), from the Chrome Dev Team, highlights the latest expansion in detail: the **Origin Private File System**, which allows to handle complete file structures on the web.

📢The File System Standard adds an origin private file system (OPFS) 📂 as a storage endpoint private to the origin of a page providing optional access to a special kind of file 🗂️ that’s highly optimized for performance.

@tomayac Just finished watching the recording of the Fugu Chat from BlinkOn 17. I particularly enjoyed the very last remark by Ben Morss: https://yewtu.be/watch?v=5Yzd3nCvIAM&t=27m25s
He refers to the recent beta release of sqlite3 WebAssembly which enables to create AND persist a sqlite database in your browser: https://sqlite.org/releaselog/3_40_0.html
For persisting the database they are using a (theoretically) unlimited 👀 browser-side storage (OPFS): https://webkit.org/blog/12257/the-file-system-access-api-with-origin-private-file-system/
