The happy 7-day break of the Chinese new year of Ox

This year’s Chinese new year (CNY) break is a little bit different for us. Because Beijing or the government in general discouraged people from returning home (due to COVID) and promoted “celebration in situ / 就地过年”, many people, including me, decided to postpone our home-returning plan. I eventually put the…

体育运动员应该先打新冠疫苗么?

This is also published at https://jiayu.substack.com/p/292 这两天正好是有报道的新冠疫情一周年,Moderna 和 Pfizer 的疫苗已经进入冲刺阶段,基本达到 90% 以上的有效性,在英美已经开始申请加急许可了。 我一直在听 Dithering,这个付费播客的两个主播 John Grubber 和 Ben Thompson 都是科技界的大佬。上一期他们讨论到一个话题,就是体育运动员(比如橄榄球队成员)能不能优先打疫苗。Ben 说这是一个 no brainer:肯定是的。 结果两天一更的节目,这一期他们就来解释澄清了,因为招致了很多反对的声音。 Ben 重申了一下他的理由:按照现在疫苗预计的生产规模和速度,和几个大型赛事参赛队伍的规模,生产后者所需要的疫苗也就是几分钟的事情,不会耽误太多医务工作者的时间;医务工作者的确是很重要的,没有说他们不应该优先,但是假想体育运动员接种了疫苗之后有什么好处:第一,大型体育赛事至少可以不带观众的恢复,很多人因此可以在家看比赛有事做,起到居家隔离的效果;第二,很多运动员带头打疫苗,对于那些对疫苗持怀疑态度的人也有一个鼓励的作用。John 笑了笑说你其实可以不用解释这么多,因为我对我们的听众有信心。

技术人的职业发展和个人成长

周五(7月31日)参与了一个同事组织的对外线上分享活动,同时也在 B 站有直播。 讨论的话题是「技术人的职业发展和个人成长」,但是主要是从 meta-thinking 的角度来阐释的,因为我本身并不认为一个人可以为另外一个人的成长和发展给特别正确的结论 — — 这个结论和决策是需要自己来亲力亲为的。 分享做的 Slides 我放到了 https://growth.jiayul.me ,以供之后参考用。

Generally I would recommend it to people with engineering background and anyone who’s interested in this field. The specialization has four courses…
