OSDNのミラーコンテンツ 2023/11/19

OSDNでのリリースファイルやソースコードは全世界の25〜30箇所程の公開ミラーサイトへミラーリングされていた。 現時点ではどれだけ生存しているかは調べていないが、まだそれなりに生きているかと思われる。ただ、日本だとJAIST(ftp.jaist.ac.jp)とIIJ(ftp.iij.ad.jp)しかないようである。

リリースファイル:

OSDNではファイルの公開方法は二種類存在し、それぞれをファイルリリース、ファイルストレージと呼んでいた。前者は最初期からあるリリースシステムであり、後者はrsync等でも利用できる置き放題のストレージシステムである。

What is the Strict Aliasing Rule and Why do we care?

(OR Type Punning, Undefined Behavior and Alignment, Oh My!)

What is strict aliasing? First we will describe what is aliasing and then we can learn what being strict about it means.

In C and C++ aliasing has to do with what expression types we are allowed to access stored values through. In both C and C++ the standard specifies which expression types are allowed to alias which types. The compiler and optimizer are allowed to assume we follow the aliasing rules strictly, hence the term strict aliasing rule. If we attempt to access a value using a type not allowed it is classified as undefined behavior(UB). Once we have undefined behavior all bets are off, the results of our program are no longer reliable.

Unfortunately with strict aliasing violations, we will often obtain the results we expect, leaving the possibility the a future version of a compiler with a new optimization will break code we th

TPM provides zero practical security

TPM (Trusted Platform Module) is as useful for preventing real attackers as the TSA is at preventing real terrorists. The architecture is fundamentally flawed and most existing implementations are completely broken. I thought this argument was settled decades ago[1] when "trusted computing" was introduced mostly as a way to provide DRM and ownership capabilities to organizations. It has largely failed to impact the consumer market when it was introduced back in the early 2000s. However, recently there seems to be a movement by certain parties to reintroduce this failed product back to the market. Microsoft argues that in order to use Windows 11, you need TPM 2.0 compatible hardware because[2]:
