陈培新，参与国信证券基础平台研发工作（DevOps、微服务治理、Serverless）

国信证券是一家全国性大型综合类证券公司，在 118 个城市和地区共设有 57 家分公司、185 家营业部，根据中证协发布的数据，近年来国信证券的总资产、净资产、净资本、营业收入、净利润等核心指标排名行业前列。

国信证券从 2020 年 6 月开始接触 TiDB，从技术预研到第一个业务上线大约花了半年时间。第一个上线的业务是金太阳帐单，后面陆续在数据中台、服务观测等系统中应用。从只在东莞主机房的 TiDB 部署到 2021 年 9 月实现 TiDB 多机房的部署，并启动国产海光 x86 服务器的试点工作，国信证券在开源 NewSQL 数据库的探索和应用层面，积累了丰富的实践经验。目前， 国信证券共有 7 个 TiDB 集群，节点数量 109 个，最大表 100 亿，支撑了托管、经纪和自营等业务。

Ignite Realtime Blog: Openfire 4.6.7 released (Log4j 2.17.1 only change)
Openfire 4.6.7 has been released with only a single change to bump the bundled log4j library to version 2.17.1. Whilst we do not believe Openfire to be vulnerable to the CVEs associated with the log4j 2.17.0 and 2.17.1 releases, we realize that many folks are running naive security scanners that are simply checking for bundled jar versions.

go 语言位操作库 bitset
bitset库 实现了 bitsets 数据结构，这是一种正整数和布尔值映射关系的结构，它比 map[uint]bool 更高效

bitsets 基本思想是用一个 bit 位来标记某个元素对应的 Value，每一位表示一个数，1 表示存在，0 表示不存在
比如我要表示 1, 3, 7 这 3 个数

1. 构造一个空白 bitsets：00000000
   
2. 每位代表的值如下：76543210

Paul Schaub: PGPainless 1.0.0 Released!
Close to the end of 2021 I’m excited to announce the release of PGPainless version 1.0.0! After a series of release candidates, it is finally time to party! The OpenPGP library successfully underwent a security audit in late November and I feel like it finally reached a state of sufficient maturity to be worthy of a major release with a “1” at the front.
