** December adventure **
Over the past couple years I’ve done the advent of code to varying degrees. I thought I was going to do it again this year but decided to try something different. I’ve been calling what came together a“ December Adventure.”

Kaidan: Kaidan’s End-to-End Encryption Trust Management

TiDB 在国信证券海量数据高并发场景中的实践
作者介绍

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。

从 0 到 1,国信金太阳引入 TiDB

国信金太阳提供证券交易、理财和资讯相关的服务。我们使用证券软件最主要的功能就是交易,在做交易的时候会比较关注收益率以及什么时候买卖股票。当前国信金太阳的 … ⌘ Read more

Peter Saint-Andre: Meditations on Bach #9: Musical Monadology
In meditation #7 of this series, I took note of some similarities between the aesthetics of Aristotle and the music of Bach. Another intriguing influence might be the monadology of Gottfried Wilhelm Leibniz (1646-1716), who directly influenced philosophers and musical theorists in the Bach’s orbit: for instance, Bach’s student Lorenz Mizler (1711-1778) was a follower of the Leibniz scholar Christian Wolff (1679-1754).
