TIL that the insect Issus coleoptratus uses mechanical gears to synchronize its legs when jumping. This is the only known occurrence of functional mechanical gears in nature.

The main mystery is the fact that adults of the same insect species don’t have any gearing—as the juveniles grow up and their skin molts away, they fail to regrow these gear teeth, and the adult legs are synchronized by an alternate mechanism (a series of protrusions extend from both hind legs, and push the other leg into action).

Burrows and Sutton hypothesize that this could be explained by the fragility of the gearing: if one tooth breaks, it limits the effectiveness of the design. This isn’t such a big problem for the juveniles, who repeatedly molt and grow new gears before adulthood, but for the mature Issus, replacing the teeth would be impossible—hence the alternate arrangement.

Well that's exceptionally neat

US Spies Are Lobbying Congress to Save a Phone Surveillance ‘Loophole’

Introduced by US representatives Warren Davidson and Sara Jacobs, the amendment, first reported by WIRED, would prohibit US military agencies from “purchasing data that would otherwise require a warrant, court order, or subpoena” to obtain. The ban would cover more than half of the US intelligence community, including the NSA, the Defense Intelligence Agency, and the newly formed National Space Intelligence Center, among others.

I guess I'm not surprised, but I didn't realize they had warrantless access to these data. With the attacks on e2e in the UK this really drives home how important encryption.

Ehhh I think the downplays the essay's excellent arfument

FTA:

THIS DISTINCTION between a “housing crisis” and a rental market that enables exploitation has practical implications. How we talk about these issues shapes what we conceive as possible and desirable responses to them.

Ya I think so. These are always tech articles and Foss software is always a big feature.

But 1password has on going audits and a sane ui and mobile apps that pass the boomer-parent test. Canadian company too which is nice given the US centric tech world.
