Habr<p>Запуск Linux внутри PDF</p><p>По мнению некоторых пользователей, PDF — простой формат для обмена документами. На самом деле это очень сложный стандарт, который поддерживает выполнение практически любого кода. Неудивительно, что в прошлые годы энтузиастам удалось успешно запустить Doom внутри PDF и провести ряд других интересных экспериментов. Оказалось, что на этом возможности движка по рендерингу PDF не ограничиваются. Он способен запустить даже эмулятор полноценного процессора, а в нём — целую операционную систему .</p><p><a href="https://habr.com/ru/companies/globalsign/articles/898056/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">habr.com/ru/companies/globalsi</span><span class="invisible">gn/articles/898056/</span></a></p><p><a href="https://zhub.link/tags/PDF" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PDF</span></a> <a href="https://zhub.link/tags/Linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Linux</span></a> <a href="https://zhub.link/tags/RISCV" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RISCV</span></a> <a href="https://zhub.link/tags/LinuxPDF" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>LinuxPDF</span></a> <a href="https://zhub.link/tags/Doom" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Doom</span></a> <a href="https://zhub.link/tags/DoomPDF" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DoomPDF</span></a> <a href="https://zhub.link/tags/TinyEMU" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>TinyEMU</span></a> <a href="https://zhub.link/tags/Emscripten" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Emscripten</span></a> <a href="https://zhub.link/tags/asmjs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>asmjs</span></a> <a href="https://zhub.link/tags/JSLinux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>JSLinux</span></a> <a href="https://zhub.link/tags/pdfsyntax" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>pdfsyntax</span></a></p>

Habr<p>CMake: Подключение riscv-arch-test для тестирования имплементации rv32</p><p>При написании своей VM для RISC-V возникла необходимость в тестировании. Сначала я пытался писать юнит-тесты самостоятельно, но выходило, что я просто копирую логику из основной. И по сути тестирую не соответствие спецификации, а соответствие моему пониманию. Через некоторое время я наткнулся на официальный набор тестов для RISC-V и решил их использовать. Это помогло найти несколько багов в моём коде.
