    The line we must draw is very, very clear.

    The world is dark and full of terrors, what else is new. We're hurtling towards economic and planetary crises in a time when authoritarianism is on the rise. Protecting, and more importantly normalizing, the right to privacy in such a world is of critical importance.

    As is tradition:

    Privacy is a human right. Encryption is a human right. No qualifiers. No ifs or buts; No reservations or restrictions. The surveillance culture we have created is immoral. No amount of good done with surveillance makes up for the evil that surveillance itself causes.

    It's been 4 weeks.

    Currently the UK publishes the same e2ee-is-bad take every 6 weeks or so with the only difference being who said it and what government scandal they are attempting to take attention away from.

    This week in 's Discreet log I cover the work creating Rust bindings for libCwtch, and demure into how please I am to see Rust doing some work to bring metaprogramming back into the mainstream with good macro support! The old Lisp programmer in me is very pleased 💜🦀

    How long do we think it will be until applications sold in the US will be required to send a report to the IRS anytime anyone opens or imports a picture depicting more than $600?

    . has decided now to completely block images of money from being opened on their application. This is insane. My job requires me to make digital illustrations. Some include images of money. This is actively stopping me from finishing my work on deadline.

    The context of all this is that I'm building a SID monitoring station as part of my ever growing radio astronomy hobby and as part of that I've been gathering quite a bit of data to hunt down interference and this signal keeps showing up, so I'm curious.

    It is between 22k and 23k (seems to be centred just off 22.5), each horizontal pixel is ~20hz.

    Question for anyone who has ever done any VLF signals stuff: Any idea what this might be? I'm willing to mark it as some weird local interference, but given that it's periodic and has a specific shape I'm interested to know if it is anything else. (1 vertical pixel ~= 1 minute)

    Anyway, very ready for a new generation of reimagined browsers. A louder echo of the early 00's niche browser renaissance.

    I feel the same way about my browser showing me ads as I do about my ISP blocking websites, or my phone manufacturer scanning my media files for contraband - it's an abuse of position, a violation of layer norms, and shouldn't be tolerated.

    Even the proposition of displaying ads directly in the address bar is enough of a proverbial straw to demolish any hope I have of a redemption arc.

    Really appreciate that Mozilla has chosen the death by a thousand cuts approach to killing Firefox. This way you really get to *feel* the pain of realizing how bad the browser ecosystem is over and over and over again.

    in furtherance of our pursuit to be professional Hackers LARPers, you can now turn on your laptop and set it to receive a file

    Incredibly proud of how this release came together. File sharing went from design to implementation across 4-different platforms in a single month. And I think it speaks to how far our little non-profit team has come. Please consider supporting us:

    For the first time, the Mac Cwtch 1.3 build was moved off the virtual server via Cwtch itself! Cwtch is now starting to be used to deploy Cwtch! In the future I am strongly thinking about an Update Bot that can tell you of new versions and just send them to you!

    Aside from inline images and audio overlays - file sharing opens up some higher level protocol options for us (e.g. larger messages, group-hosted messages, content-addressable messages) which I am excited to start experimenting with.

    We are being deliberate about file sharing. As critical a feature as it is there are also many risks in a metadata resistant setting. For now you will have to explicitly opt-in to enabling file sharing, and Cwtch will not attempt to open any received files.
