The pandemic is back

 According to this report, despite the vaccination and other efforts, the daily new COVID-19 cases has reached the 200,000 mark on August 17 in the US. It appears that a new wave of the pandemic has begun. 

Obsidian

 I have been searching for a note taking/management tool for some time. From a book, I encountered Roam, which looks exactly what I need. After some research, I realized that is is a proprietary software using proprietary data storage format, and store all data on a remote cloud server. This, along with its not so modest price tag, raises a red flag. 

Then I discovered Obsidian, which is itself proprietary (as opposed to open source) but it works on local, plain text (including Markdown) files, which can be opened and modified by any text editors. For now, it looks really promising!
