Dilley adjusted the sensor so that it registers an infrared reflection for red pieces, but not black pieces. Each column has its own sensor, so the Arduino can recognize the colors of the entire bottom row. It then sets the positions of the flaps accordingly using servo motors controlled through a servo shiel [13:42] schestowitz d. Finally, another servo quickly releases the bottom row and then moves back to block the following row. That process repeats until all the pieces have been sorted.

[13:44] schestowitz[13:44] schestowitzFirst, and most importantly: FreeBSD PF developers work with OpenBSD devs all the time, and OpenBSD PF developers pull stuff from FreeBSD1. You get a lot of noise about certain people being jerks about the other projectand both projects absolutely have jerks. (And yes, anyone who has read my books knows that I am a cross-platform jerk.) But for the most part, folks want to work together.
[13:44] schestowitzPF is absolutely an OpenBSD creation, though, so why isnt the OpenBSD version the Single Source of Truth? Why doesnt FreeBSD just consider OpenBSD a vendor and pull that code in? Because the OpenBSD and FreeBSD kernels are wholly different.

To create an art piece, the machine first has to insert dozens or hundreds of nails into the foam bed. That necessitated the invention of a mechanism to feed nails and a neural network to verify that each nail feeds properly. The machine then has to convert an ima [13:49] schestowitz ge into a string path, with that path avoiding collisions with nails, looping around nails enough to maintain tension, generating the proper string density, and preventing any tangles.

[13:50] schestowitz[13:50] schestowitzThe Raspberry Pi 5 is here and we have already reviewed it, pushing it to its limits, or so we thought. Just how far can you push a Raspberry Pi 5? We decided to take it upon ourselves to overclock both the impressive 2.4-GHz Arm Cortex-A76 64-bit CPU and the new 800 MHz VideoCore VII GPU and found we could push both to new heights of 3 GHz and 1.1 GHz.
[13:50] schestowitzWith the overclocks, we got noticeably better performance -- up to 25% in some processor-heavy workloads. However, on graphics-intensive tasks such as video streaming or gaming, we didn't see many gains.

[16:30] schestowitzThe joint advisory was issued today by the U.S. National Security Agency, the Federal Bureau of Investigation, the Cybersecurity and Infrastructure Security Agency, the Japan National Police Agency and the Japan National Center of Incident Readiness and Strategy for Cybersecurity. It warns of a threat actor known as BlackTech.

[16:44] schestowitz[16:44] schestowitzThis is an important dynamic to understand, because this is only available to Trump because the Democrats have betrayed voters, ceded this territory. This used to be an issue for the left. I came up in the alter-globalization movement. It didnt used to be reactionary to talk about these trade deals, but it does point to the fact that this has not been an issue on the left for a long time and [16:44] schestowitz its dangerous to create that kind of political vacuum.

[16:58] schestowitz[16:58] schestowitzHowever, this was a kind of free speech which was unconsciously contingent on being used for speech with which the listener was comfortable. The hacker community at this time was largely homogeneous, and as such most of the speech we were exposed to was of the comfortable sort. As the world evolved around us, and more people found their voice, this homogeneity began to break down. Critics of radical fr [16:58] schestowitz ee speech, victims of hate speech, and marginalized people of all kinds began to appear in hacker communities. The things they had to say were not comfortable.
