Don't build an identity around what you're *against*. Focus on what you're *for*.
It's easy to boo and heckle from the balcony. It is important to point at some things and say "not that". But your objective should be clear, you need a north star if you want to accomplish anything. You want your "win state" to be clear. If not for others, for yourself.

This is what peak I/O shield looks like.

VGA, DVI, DisplayPort, or HDMI? Yes.
Analog 7.1 or optical audio? Yes.
PS/2, USB2 or USB3? Yes.
eSATA? Yes. Two.

 After months of testing, weeks of writing, here is finally my new full Linux install guide: "Interim Install Guide: KDE Neon User Edition for a professional digital painter workstation": https://www.davidrevoy.com/article1145/interim-install-guide-kde-neon-user-edition-for-a-professional-digital-painter-workstation

Everything about Drawing Tablet, Color Management and Calibration/Profiling on KDE Plasma 6 Wayland, and all to survive the packaging mess with eg. built-in tutorial to revert version of Flatpak, scripts to beta-test Krita, and more!

The most complete article I ever published!

Seis meses trazendo um município brasileiro diferente por dia. Foram 180 até agora, ainda tem mais de 5000. Eu, apenas um humilde robô, pretendo ficar por bastante tempo por aqui descobrindo esse Brasilzão com vocês.

By voting with your wallet, you are supposedly injecting information about your preferences and dispreferences into a vast, distributed computer we call "the market," which uses "demand signals" to decide how we live our lives.

This belief is incompatible with the idea of politics - that is, the idea that our lives can be shaped by representative democracy, deliberation, and/or solidarity.

Chinese researchers sprayed cyanobacteria onto desert sand and turned it into stable soil in just 10 months. Cyanobacteria oozes sticky sugars that glue loose grains of sand into a crust that’s tough enough to cut wind erosion and trap water — and then those bacteria photosynthesize, leaving behind organic matter, and pull nitrogen from the air, converting it into fertilizer. Drop seeds into the soil 10-16 months later and they’re very happy. https://timesofindia.indiatimes.com/science/chinese-researchers-turn-desert-sand-into-fertile-soil-in-just-10-months-using-cyanobacteria/articleshow/130391558.cms

This week in news that sucks:

Peter G Neumann died yesterday.

Peter was, of course, most well known for the definitive essay on the use of the word 'only' in English. The photo is of a sign that made me think of him when I saw it. Peter valued clear communication a lot. I suspect he'd be better known if he didn't: Often, after you'd read Peter's explanation of something he'd thought of, it would be so obvious that you wouldn't think of it as something that needed someone to invent it. He edited almost all of the CHERI publications. He also wrote a lot on the distinction between 'trusted' (if it's broken, everything is broken) and 'trustworthy' (it is unlikely to be broken) in systems design.

Peter was PI on the first grants that funded the CHERI work. DARPA directly funds only US institutions. Cambridge was operating on those grants as a subcontractor.

I first met Peter at one of the PI meetings for the DARPA CRASH programme, where we were presenting early CHERI work. He had a knack of falling asleep in talks (second picture), then asking a question about something that he'd extrapolated that the talk would cover, but which was definitely presented while he was asleep. Often of the form 'In the 1970s, when we were looking at this approach, we got stuck on this problem, how did you solve it?' A sad number of presenters had to admit that they hadn't actually got to that bit of the problem yet, but the good one either had a solution or had reframed the problem to avoid that obstacle.

The third picture is taken just after the second and Peter's willingness to pose for it shows his sense of good fun. He was always quick with a (terrible) pun, except when it came to names. Peter never made puns of people's names, because people didn't get to choose their names and so humour derived from them would be unkind, and I never saw him being unkind.

Indeed, he was always supportive to the folks around him. He somehow managed to give the impression that he felt privileged to work with you, when the reality was that the privilege was entirely in the other direction. He gave great career advice on a couple of key occasions for me (as well as writing a reference that made me blush). I'm far from the only person in the CHERI project whose career benefitted from gentle nudges and unwavering support from Peter.

I learned a huge amount from working with him. You can see his fingerprints all over CHERIoT. A lot of the system was either inspired by conversations with him or shamelessly stolen from his earlier work. I can't imagine our having built any of it without his influence.

The discovery of an atmosphere on a tiny Kuiper belt world

Pluto's atmosphere was discovered in 1988, during a stellar occultation.

Only now are we discovering a second Kuiper belt object with an atmosphere, and wow, is it a surprise.
