A Static Art Gallery with Hugo

This is not the first time, and won’t be the last time I post about JS-free, bloat-free web. In this post I’d like to share how I build a art collection site for my gf.

Hello html

ELF, symbol table, and dynamic linking (WIP)


This is work in progress

How much Page Tables / PTEs are needed for xyz amount of memory?

TL;DR; For m bytes virtual memory (up to 256T), you need 1 + m/2M + m/1G + m/512G pagetables on all levels, each taking 4K in space. Pagetables take roughly 1/512 proportion to virtual memory size.

The openring is a program written in GO that pulls RSS feeds from a list of URLs and render 3 of the newest articles into html that can be integrated into static site generators. The webring is a well maintained collection of blogs:

Chinese translations of computer terminologies (WIP)

The meaning is distorted when terminologies are translated, even if they are translated by the literal meanings. In this post I list some translations that I think are “bad”, and hopefully some better translations. (well, unluckily for most of them I can’t think of a better one.)

schnitzel.nvim : my neovim config

schnitzel.nvim is the neovim config that I daily drive. Some friends asked for my dotfile, so I made a public version of it.

Binary Hacks - Dump process virtual memory

  2. get the memory mappings cat /proc/[PID]/maps
  3. identify the memory range of interest
  4. connect gdb to pid and dump memory:
