schestowitz                                        <p>An Arduino Mega 2560 detects whether a piece is red or black using an infrared sensor. 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 shielSep 30 13:42
schestowitzd. 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.</p>Sep 30 13:42

schestowitz                                    <blockquote>Sep 30 13:44
schestowitz                                        <p>First, 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 project–and 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. </p>Sep 30 13:44
schestowitz                                        <p> PF is absolutely an OpenBSD creation, though, so why isn’t the OpenBSD version the Single Source of Truth? Why doesn’t FreeBSD just consider OpenBSD a vendor and pull that code in? Because the OpenBSD and FreeBSD kernels are wholly different.</p>Sep 30 13:44

schestowitz                                        <p>Paul spent years working on this project and it shows. Every step of the process required trial-and-error with different prototypes. 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 imaSep 30 13:49
schestowitzge 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.</p>Sep 30 13:49

schestowitz                                    <blockquote>Sep 30 13:50
schestowitz                                        <p>The 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. </p>Sep 30 13:50
schestowitz                                        <p> With 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. </p>Sep 30 13:50
