Week 13 - 2019

The weeknote for 3/25 - 3/31.

OSS

🦕 Deno is a new JavaScript runtime.

In this and last week, the internal structure of deno has been changed very much. //core/ has become the new central part of deno as its name indicates. The crate name of //core/ directory is now deno, and //core/ includes libdeno as //core/libdeno. //src/ has become //cli/. The crate name is now deno_cli. @keroxp reports that the new core is a bit unstable, and listen and accept sometimes behave in a buggy way. Probably we seem needing some more time to stabilize it.

📊 C3 is a chart library based on D3.

Released v0.6.14
- which includes an important bug fix #2589. This PR fixes the memory leak behavior which only happens when the tab is inactive (i.e. in background) and chart loads the data dynamically. This bug seems to have existed for really long time in c3 codebase. Thanks @pstromberg98 for sending the PR and thanks @NickJSpencer for giving the initial idea where the leak happened.

Seen Spider-Verse in Tachikawa Cinema City. I liked it. The story is not of an extroadinary type, but the visual expression was really awesome. The shader looks different from the other hollywood animation movies. The last scenes were something I've never seen before and it was beautiful.

I submitted the document of the consumption tax to the tax office for the first time in my life. In Japan, a self-employed person is allowed to avoid paying consumption tax to the goverment unless their revenue exceed 10M yen in the year before the accounting cycle. My revenue exceeded 10M in 2016 and now its first time to pay it to the government 😂 The document itself is very easy to create by using the website of the tax office. It almost automatically calculates everything from what I entered as the balance sheet. When I submitted it, the office was very empty unlike the ordinary (income) tax document submission sites.
