• 看看？ Antmicro blogged about optimising LLVM for machine-generated C++ code as produced by Verilator.

• Renato Golin provided an update on the MLIR project charter and restructuring survey noting that the survey is now closed as it has been flagged as violating Google's terms of service, with no functional route to ask for manual review.

本周推荐：《我看见的世界》

作者：李飞飞

推荐：小编1号

在AI领域以ImageNet著名的李飞飞教授的最新自传。书中是以AI的历史和个人的历史穿插进行回忆的。AI的部分我比较熟悉（2016-2017我做过很多次AI科普讲座），而李飞飞教授个人部分是第一次完整的看到。这是一个活生生的、完整的华人奋斗的故事。书中描述的李飞飞的妈妈在每一次家庭贫穷导致李飞飞对职业选择的犹豫时候的坚定态度，仿佛是那个年代无数个（无论是身处中国大陆还是旅居海外）父母的声音的叠加。

当阅读到李飞飞教授描写的家庭讨论的时候我会心中涌出一些窘迫，就好像是交谈的双方，对方有完全坦诚的方式诉说自己的故事，而我自己却无法想象以同样的坦诚去打开自己。

推荐所有的伙伴都阅读这本书。
