Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

  1. 对于bit操作，分成redis操作和mysql操作。redis上对字符，mysql对整数（integer）

  2. util/converter，进行 string（长度固定，4byte）<========>integer(mysql)之间的操作，以便把string变成int，放入mysql，或者反过来，变成string后放入redis

  3. util/int，对integer进行bit操作

  4. bit, 直接对redis中的key进行bit操作，key对应的字符长度任意

  5. mysql中存储的权限是按照字节格式，即左边是高位，右边是低位，[privilege3,privilege2,privilege1,privilege0]，而redis则正好相反，所以从mysql计算absPos，需要取反 例如[10000000 00000000 00000000 00000000,0,0,0]，计算absPos，应该是127-332-38-7=0，即127-fieldOffset23-bitOffset8-bitOffset=0
