RACE is an open source project aimed at developing technologies to provide metadata-anonymous, secure, and resilient messaging for users around the world. RACE provides anonymity by routing messages through an overlay network of volunteer servers using cryptographic algorithms that prevent a malicious subset of these servers from determining who is messaging whom. RACE uses specialized networking protocols to prevent connections between individual members of the network from being detected or blocked. RACE is built to run in a dockerized linux environment and on Android devices.

The Hacktic Demon Dialer is a compact inband signalling device, aka a blue box. With many additional features. The DemonDialer was designed by Hacktic in 1991, see hacktic 14-15. The original design notes and schematics have been located, scanned, and cleaned up. The documentation has been assembled into PDFs for printing and binding.

To help people who want to repair their vintage IBM EGA cards, I've put together this reference schematic and layout. The schematic is closely modeled after the schematic in the IBM technical reference material but with mistakes corrected and more information added. The PCB layout is closely matched to the original card. Using KiCad, you can click on a component on the schematic and it will automatically highlight it in the layout, so it's perfect if you need to probe pins with a scope, logic analyzer, or even just a multimeter.
You might be excited about fabricating this board so you can have your very own clone of the EGA card, but unless you have the full set of custom chips, the board will be useless.

The LoongArch architecture is an Instruction Set Architecture (ISA) that has Reduced Instruction Set Computer (RISC) style. The LoongArch Reference Manual is used to explain the LoongArch specification.
LoongArch has the typical characteristics of RISC. LoongArch instructions are of fixed size and have regular instruction formats. Most of the instructions have two source operands and one destination operand. LoongArch is a load-store architecture; this means only the load/store instructions can access memory the operands of the other instructions are within the processor core or the immediate number in the instruction opcode.
LoongArch is divided into two versions, the 32-bit version (LA32) and the 64-bit version (LA64). LA64 applications are “application-level backward binary compatibility” with LA32 applications. That means LA32 applications can run directly on the machine compatible with LA64, but the behavior of system softwares (such as the kernel) on the machine compatible with LA32 is not guaranteed to be the same as on the machine compatible with LA64.
LoongArch is composed of a basic part (Loongson Base) and an expanded part, as shown in the figure. The expansion part includes Loongson Binary Translation (LBT), Loongson VirtualiZation (LVZ), Loongson SIMD EXtension (LSX), and Loongson Advanced SIMD EXtension(LASX).

VIM has all features of a modern programmer's editor - macro language, syntax highlighting, customizable user interface, easy integration with various IDEs plus a set of features which makes VIM so attractive to its users: crash recovery, automatic commands, session management. I started this tutorial for one simple reason - I like regular expressions. Nothing compares to the satisfaction from a well-crafted regexp which does exactly what you wanted it to do :-).
