- The document contains code and explanations for solving optimization problems using dynamic programming, including calculating minimum costs using a 2D array to store results.
- It describes applying dynamic programming to problems involving finding minimum costs for tasks that can be split into subtasks, with the overall cost determined by combining subtask costs.
- The code provided shows initializing a 2D array and using nested for loops to iterate through values, calculate minimum costs based on previous results, and store them in the 2D array to build up an optimal solution.

新卒3ヶ月でRustで動くサービスを立てられそうなので、それについて話します。
なぜRustで書くのか、どのようにしてRustで書くことを受け入れてもらえるかという観点から、現状と今後のプランについて話せたらと思っています。

Proving Decidability of Intuitionistic Propositional Calculus on CoqMasaki Hara
?
The document discusses proving the decidability of the intuitionistic propositional calculus (IPC) on the Coq proof assistant. It outlines the methodology as: 1) Eliminating the cut rule through cut elimination, 2) Eliminating the contraction rule, 3) Splitting the →L rule into 4 pieces, and 4) Proving that every rule is strictly decreasing under a well-founded relation. This will prove the decidability of IPC by showing that all rules are finitary. Details are provided on implementing cut elimination and contraction elimination in Coq.
IoT Devices Compliant with JC-STAR Using Linux as a Container OSTomohiro Saneyoshi
?
Security requirements for IoT devices are becoming more defined, as seen with the EU Cyber Resilience Act and Japan’s JC-STAR.
It's common for IoT devices to run Linux as their operating system. However, adopting general-purpose Linux distributions like Ubuntu or Debian, or Yocto-based Linux, presents certain difficulties. This article outlines those difficulties.
It also, it highlights the security benefits of using a Linux-based container OS and explains how to adopt it with JC-STAR, using the "Armadillo Base OS" as an example.
