Ruben Schade ☛ Shinri and Reine found me some PS/2 cables!
Last Saturday I talked about buying a KVM for my stack of old computers, on account of having no space. The unit didn’t come with cables unfortunately, and tracking down ones that didn’t end up costing as much as the unit itself was difficult.

CNX Software ☛ Microchip PIC18-Q24 8-bit MCU focuses on security and supports Multi-Voltage I/O (MVIO)
The newly introduced Microchip PIC18-Q24 8-bit MCU implements security measures such as the Programming and Debugging Interface Disable (PDID) feature and optional support for an immutable bootloader, as well as support for Multi-Voltage I/O (MVIO) to interface with digital inputs or outputs at different operating voltages without the needs for level shifters. While it’s fun to find a new MCU platform that you can hack via serial, JTAG, or other debug interfaces, it can be a security issue, and the Microchip PIC18-Q24 aims to make that impossible by disabling programming and debugging interfaces and the 8-bit microcontroller also offers an option to make the bootloader impossible to modify once a specific configuration bit has been set.
