PS/2 vs USB


PS/2 is a “port” while USB is a “bus” .
The difference is a port is designed to connect a single device, while a bus is designed to connect many devices together. They can all be connected to a single USB host controller using a hub. With PS/2 I’d need a separate connector for each device.

canary test

In software testing, a canary is a push of programming code changes to a small group of end users who are unaware that they are receiving new code. Because the canary is only distributed to a small number of users, its impact is relatively small and changes can be reversed quickly should the new code prove to be buggy.

Orbital Edge Computing: Nanosatellite Constellations as a New Class of Computer System

From:包云岗

2020年度计算机体系结构/操作系统/编译编程三个领域综合的国际顶会ASPLOS最佳论文奖之一是来自CMU的一项关于卫星集群的工作：《Orbital Edge Computing: Nanosatellite Constellations as a New Class of Computer System》。作者认为卫星集群将会是一种新的计算机系统。
我们组里研讨过这篇论文，其实技术上并没有特别大的突破和新的洞察力，实验也还只是在模拟器进行。获得最佳论文奖主要还是因为给大家畅想了一个未来愿景。

x86-64 canonical address

https://stackoverflow.com/questions/25852367/x86-64-canonical-address

In 64-bit mode, an address is considered to be in canonical form if address bits 63 through to the most-significant implemented bit by the microarchitecture are set to either all ones or all zeros.

I.e. a canonical virtual address is 48 bits correctly sign-extended to 64. If the high bits don’t match, it’s non-canonical and will fault if you attempt to dereference it.

Xenomai is about making various real-time operating system APIs available to Linux-based platforms. When the target Linux kernel cannot meet the requirements with respect to response time constraints, Xenomai can also supplement it for delivering stringent real-time guarantees.
