In the 1960s, the B-52 bomber could navigate by the stars. Celestial navigation requires spherical trigonometry, so an analog Angle Computer solved these equations electromechanically. Let's look inside...

Every employee at my company starts at $33/hr. We are on track to post a half million dollars this year.

Never let them tell you they can't pay you a living wage.

What they mean is they WON'T pay you a living wage.

We've released a demo of the project @CanLehmann and I have been working on: @verijit is a meta-tracing Verilog emulator that specializes the simulated core to the machine code that is being executed on top of it. Was lots of fun to work on! I'm quite happy with the results too, we reach two orders of magnitude improvement over Verilator for a simple RISC-V core

Retraction Watch reports on the mass resignation of the editorial board of the _Journal of Approximation Theory_ (Elsevier), https://retractionwatch.com/2026/04/16/45-editors-resign-from-math-journal-former-eic-calls-elsevier-publisher-a-mini-dictator/

This follows in close succession from the mass resignation from _Communications in Algebra_ (Taylor & Francis), https://retractionwatch.com/2026/03/17/communications-in-algebra-taylor-francis-editors-mass-resignation/

45 editors resign from math journal, former EIC calls Elsevier publisher a ‘mini-dictator’

Forty-five of 48 members of the editorial board of the Journal of Approximation Theory resigned earlier this month for what they called Elsevier’s “concerning and potentially detrimental” decisions…

BABY GOATS!!! The first mama has 2 healthy babies!

They are dried off, warmed up, and starting to try to nurse so I'm back inside warming up for a bit.

From the Anti-Authoritarian Playbook;

“The targeting of trans people - and specifically trans youth and trans women in sports - is not a policy agenda. It is a strategic operation. Understanding it as policy produces the wrong response. Understanding it as strategy produces the right one.

Jason Stanley, in How Fascism Works, identifies the targeting of vulnerable minorities as a core mechanism of authoritarian consolidation. The function is not primarily to harm the targeted group, though that harm is real and intentional. The primary function is to test the solidarity of potential opposition coalitions, to find and exploit the fracture lines, and to establish a precedent: that some members of the coalition can be sacrificed when the political cost of defending them is judged too high.

Every successful authoritarian project has done this. The question it is always asking of the opposition is: is there anyone in your coalition you will abandon to protect the rest? Because if the answer is yes, we know exactly how to proceed. We find that person. We make defending them as costly as possible. And we watch the rest of the coalition either hold together or fracture. If they fracture, we learn where the next fracture line is, and we push there.

The targeting of trans people is not the end of this strategy. It is the test. And what the test is measuring, in real time, is whether LGBTQ organizations, progressive coalitions, and pro-democracy movements will sacrifice their most vulnerable members when the pressure is sufficient.
