I realized I've been a member of the @csswg for more than half of my life (as of sometime late last year). One of the results of getting involved with something when young, and staying involved...

(Also, I have a vague sense that git identifies things other than revisions by these hashes as well, so there may be other things I should be examining for collisions. But I'm not that much of a git expert.)

(I'm using "git log --format=format:%h" as the definition of what git shows.)

It turns out that for the Chromium repository, 12 digits is not enough. There are two revisions in the repo whose initial 12 digits are the same, 72d496d75536. (If it weren't for that pair of revisions, 10 digits would be good enough. But 9 digits has quite a few collisions.)

A random discovery today about the Chromium git repository at chromium.googlesource.com/ch… . git varies the length of the short hashes it shows based on an estimate of the repository's size. For Chromium it shows 12-digit short hashes.

"But buying in the Bay Area has always been hard!" "NYC is dense but still unaffordable!" Reality check: From '91-'21 it became nearly *2x HARDER* to buy here! Compare the ratios to NYC! It was even easier in 80s when they bought! Help stop the lies! tinyurl.com/HomePriceIncomeR…

Based on my very limited understanding of the spec, it seems like both implementations are both quite incomplete (in different ways) and have a number of bugs. But the spec is quite complicated, and I'm really not sure.

Some of the things I tried are in the demo at dbaron.org/css/test/2021/off… . Interoperability is not good... and wpt.fyi/results/css/motion?l… doesn't have very many tests.

It turned out interoperability of CSS Motion Path (drafts.fxtf.org/motion-1/) is not very good... and I couldn't actually find a value that did what I wanted without falling back to a degenerate path ("M 0 0").

So I wanted to test the stacking context and grouping effects of offset-path, so I thought I'd look for a value of offset-path that: (a) was supported in Firefox and Chrome and (b) didn't cause the element to move at all. (The goal was a row in dbaron.org/css/test/2018/sta… .)

Bullshit. It doesn’t matter if we build renewable energy if all that energy is wasted. Replace *all* energy generation with clean, climate neutral sources, then we can talk about using the excess for play money (and after we use all that processing to cure all diseases, etc).

Breaking: Facebook plans to stop shielding politicians from the content rules it applies to everyone else, a sharp reversal from its position that all speech from elected officials is inherently newsworthy. Could have big ramifications globally! theverge.com/2021/6/3/224747…

nytimes.com/2021/05/31/world… blames proportional representation in general, but the specific rules seem likely to matter. Israel's threshold to get seats is 3.25%. In Germany it's 5% (or 3 seats), in New Zealand 5% (or 1 seat), in Sweden 4%. Denmark is 2% but also has many parties.

Bennett: “I’m going to work with all my strength to form a unity government with my friend Yair Lapid. All the parties are invited to take part. None of us can fulfill all our ideologies but this will be a government that will not be against any part of society, but for everyone”
