I recently tried to upload the Linux kernel document which is generated in html form using the Sphynx build system[1] on a Github page[2] so that people can read DAMON[3] document from everywhere. The upload was very easy. I simply created the repo, put the generated html doc at Documentation/output/ into the repo and pushed. However, the theme was not applied. Github assumes every Github pages to be based on Jekyll[4], and because every files and directories starting with underscores are handled special in Jekyll, some directories Sphynx created were ignored....

ACM has decided to allow open access to every article in ACM DL until June 30, to help people doing remote works due to COVID-19. I found this by checking my papers in ACM DL. I believe this is a great decision of ACM.

With the upload of the accepted papers list, EuroSys homepage also updated its notice about COVID-19 related notification. It previously tried to reschedule the offline meeting, however seems they changed mind and decided to do virtual (online) conference. It’s a bad news for authors and people who planned to participate the offline meetings, but a good new for other people, because they would be allowed to participate in the conference without fee....

Read-copy update (RCU) can provide ideal scalability for read-mostly workloads, but some believe that it provides only poor performance for updates. This belief is due to the lack of RCU-centric update synchronization mechanisms. RCU instead works with a range of update-side mechanisms, such as locking. In fact, many developers embrace simplicity by using global locking. Logging, hardware transactional memory, or fine-grained locking can provide better scalability, but each of these approaches has limitations, such as imposing overhead on readers or poor scalability on non-uniform memory access (NUMA) systems, mainly due to their lack of NUMA-aware design principles....
