Linux Development History Visualization Youtube Channel

I created a Youtube channel[1]. I will upload videos for the git history between each release of the Linux kernel, just for jun. I use gource[2] for the visualization for now. The scripts I use for these videos are available[3] under GPL v3. If you want, you may use the scripts for your own video generation.

DAPHICX: Data Access Pattern Hint Injecting Compiler Extension

Memory pressure is inevitable as the size of working sets is rapidly growing while the capacity of dynamic random access memory (DRAM) is not. Meanwhile, storage devices have evolved so that their speed is comparable to the speed of DRAM while their capacity scales are comparable to that of hard disk drives (HDD). Thus, hierarchial memory systems configuring DRAM as the main memory and high-end storages as swap devices will be common....

Fedora28 ibus-hangul input problem

어느날부터 Fedora 터미널에서 한글 입력이 매우 불편해졌습니다. 한글 모드에서는 backspace, enter, esc 등의 특수키가 하나도 안먹힙니다. Vim 을 쓰는 입장에선 매우 불편하죠. 알고보니 ibus-hangul 버그인 것 같습니다[1]. 아래 커맨드로 ibus-hangul 을 문제 없던 버전으로 다운그레이드 시키고 세션을 재시작 하면 문제가 사라집니다. sudo dnf downgrade ibus-hangul-1.5.0-12.fc28.x86_64 [1] http://www.fedoralinux.or.kr/board-read.do?boardId=bbs3&boardNo=153170459823549&command=READ&page=1&categoryId=-1

I will have a talk at the Hotstorage'19

HotStorage'19 에 제출한 제 최근 연구에 대한 논문이 accept 되어 7월에 해당 워크샵에서 이에 대한 내용을 발표하게 되었습니다. 논문 제목은 “Automating Context Based Access Pattern Hint Injection for System Performance and Swap Storage Durability” 입니다.
