They told us this would happen if we voted for Harris

Anytime you go to a protest, learn more about what the plan is. Well organized protests have an outline of what to expect and if the protest begins to deviate from that plan, be skeptical.

It could simply be a change of plans or adaptation, but there are often people who show up trying to hijack the group for their own ends. Once you're able to get a group to follow one instruction in unison, it's much easier for provocateurs to strike.

Every interaction I’ve had with Clear at an airport is creepy. They literally guide you into the line like it’s open and ask for your ID as a sign-up stunt. It’s like they’re elbowing you out of the regular or Pre-check line.
Welcome back, Karl.

oooh excited to see a new newsroom serving the tenderloin in SF!

it'll be published as a zine, distributed by hand, with material also online. email list signup is here: https://www.tlvoice.org/about/#/portal/signup

About the Tenderloin Voice

The Tenderloin Voice is a newsroom serving San Francisco's Tenderloin community and was built in collaboration with residents. We practice a model of journalism that shares editorial power with audiences. We do this by:  * Asking the community what they want us to cover, and then covering it. * Inviting community members

The Tenderloin Voice

I didn’t have “time travel” anywhere near the top of my “next grift after AI” list. The chronomigration bubble came out of a confluence of developments; gamma ray telescopes sensitive to the 500 keV electron-positron annihilation energy allowed us to spot the inbound antimatter comet 67i/Fermi as soon as it began interacting with the solar wind. Gravity tugs brought 67i to lunar orbit, where laser ablation was used to direct a stream of antimatter dust onto fuel pellets (just moon rocks, in fact). The plume of energy liberated by quantum annihilation acted as a giant rocket motor, slightly perturbing the moon’s orbit in such a way to tug the earth farther enough away from the sun to cool the climate. It will take four hundred centuries, which is where the time travel (also facilitated by the matter/antimatter energy fountain) comes in. If you can afford the fare, you can deposit one dollar in a savings account, blip out of our climate ravaged world and arrive rich in the clean, comfortable future. No, you cannot deduct the cost from your future fortune, it doesn’t work like that. It doesn’t work at all. The kind of person who would take this offer can’t be expected to know the difference between a time portal and a disintegration field. And they just won’t believe you when you warn them.

good days in my mind

I was recently reminded of this.

A couple decades ago, I wrote a short paper that described how the basic approaches of cryptography and computer security lead to an efficient and practical privilege escalation attack against master-keyed mechanical locks, which I published in IEEE Security and Privacy (a nerdy computing technical journal).

TL;dr: Master-keyed locks have fundamental, exploitable weaknesses.

But I wasn't ready for what happened next.

Ok. Booze time. We’re going with a blend of smooth Jamaican rum, overproof rum, cognac and bourbon. I had planned to use my big bottle of Elijah Craig, but it turns out it’s now my big bottle of homemade amaro. I’m also out of allspice dram, so good thing I did the spices this morning. 🤷‍♂️ 7/
