生态环境部大气环境司有关负责人称，在主要考虑大气污染治理成本和中长期健康收益的情况下，标准修订产生的治理投入与健康收益的比值接近1:10。通俗地理解，每投入1元钱用于治理，预计未来能产生约10元钱的健康回报。同时，随着空气质量持续改善，能够延长国民平均预期寿命，节省居民医疗支出。

Back in 2024 I learned about SDF (signed distance field) rendering of fonts. I was trying to implement outlines and shadows in a single pass instead of drawing over the text multiple times in different styles. I intended to use these fonts for two different projects, a game and a map generator. I got things working but didn’t fully understand why certain things worked or didn’t work. I wrote some notes on my site about what I tried. In the end, I stopped working on both the game’s fonts and the map generator, so I put all of this on hold.，这一点在新收录的资料中也有详细论述

Many drives are not much bigger than the USB-A connector, but I find them a little too easy to lose. If you need a teeny-tiny drive, they don’t come much smaller than this one. Verbatim’s 32 GB Nano did slightly better than the stated 80 MB/s read and 25 MB/s write speeds in my testing, but it’s still quite slow. I like the curved indent that makes it easier to extract, since some of these tiny drives are hard to pull out. The blue finish lacks style, but it is easy to spot if you drop it, and it is very affordable. There are also 16- and 64-gigabyte models. Verbatim offers a two-year limited warranty on its drives.
