Linux Support Is Coming To Allow De-Authorizing Thunderbolt Devices

While in recent years there has been growing interest in enhancing Linux's Thunderbolt security with offering security levels and other functionality to authorize supported/known Thunderbolt devices, surprisingly it's taken until 2021 to see the ability for Linux's Thunderbolt software connection manage to handle de-authorizing devices. If wanting to de-authorize a previously authorized Thunderbolt device for whatever reason or if wanting to establish policies like where on user log-out that devices would be automatically de-authorized, it's looking like Linux 5.12 will support this ability.

• C++ Standard Conversions

  There are two entity types in C++, the fundamental types and the compound types. The fundamental types are the scalar types. The compound types are the rest of the entity types. Conversion can take place from one entity type to another appropriate type. [...] The output is 2, 2, meaning that the program has returned the square root of 5 as 2 and the square root of 8 also as 2. So, the first two statements in the main() function have floored the answers of the square root of 5 and the square root of 8. This article does not discuss flooring or ceiling in C++. Rather, this article discusses the conversion of one C++ type to another appropriate C++ type; indicating any approximation in value made, loss of precision, or constraint added or removed. Basic knowledge of C++ is a prerequisite to understand this article.

  I've always wanted to be able to set up a full consul, nomad, vault, etc. environment (along with hosted applications) with a single "terraform apply." I've spent a few weekends on this now and wanted to give a small tour, although it's still a work in progress.
