Alex Courouble: Token-level git blame

Session information has not yet been published for this event.


One Line Summary

Some scripting to obtain token-level git blame results.


Git blame currently assigns “blame” for code at a per-line granularity.
Through the use of some scripting, token-level granularity can be achieved.
Using the historical documents, blame can be assigned on a complete Linux kernel back to its starting days.

    When Jon grows up, he will do something incredible. In the meantime, he’s spent a lifetime doing random things. After growing up in Japan, he did a double tour through Purdue and received a BS and MS in Computer Science.

    Fat lot of good that did, as he then landed in one programming job after another. First Convex for years implementing compilers that could do automatic vectorization, parallelization and inter-procedural transformations. He tried his hand writing client-server code to do Healthcare messaging system integration stuff. And then a bunch of network installation, database and web goo.

    During the Dot Bomb Era, Wifi and wireless AP design took its toll on Jon as he discovered that Spokane WA was a desert, figuratively and literally.

    But that set the stage for a move to Austin Texas where he embarked on some PowerPC Kernel and U-Boot programming. It was an easy slide into Git from there. Hitting rock bottom, he wrote “Version Control with Git” published by O’Reilly Media.

    Then, climbing back toward civilization, he wrote ports to ARM SoCs for 6 years and two companies, one died in a startup collapse, the other was soul sucking.

    These days, Jon makes beer and wine, and develops products for Netgate.
