Wellness Wednesday for December 28, 2022

The Wednesday Wellness threads are meant to encourage users to ask for and provide advice and motivation to improve their lives. It isn't intended as a 'containment thread' and any content which could go here could instead be posted in its own thread. You could post:

  • Requests for advice and / or encouragement. On basically any topic and for any scale of problem.

  • Updates to let us know how you are doing. This provides valuable feedback on past advice / encouragement and will hopefully make people feel a little more motivated to follow through. If you want to be reminded to post your update, see the post titled 'update reminders', below.

  • Advice. This can be in response to a request for advice or just something that you think could be generally useful for many people here.

  • Encouragement. Probably best directed at specific users, but if you feel like just encouraging people in general I don't think anyone is going to object. I don't think I really need to say this, but just to be clear; encouragement should have a generally positive tone and not shame people (if people feel that shame might be an effective tool for motivating people, please discuss this so we can form a group consensus on how to use it rather than just trying it).

DDIA is the standard resource here. Read it twice, take notes.

Papers from Will Larson's Staff Engineer (ranging from DynamoDB, Raft, Paxos, GFS, etc.) are worth perusing as well (and will pop up as references from DDIA).

Signals and Threads have a few episodes that I think are particularly relevant for system design, and the entire podcast is definitely worth a listen at some point. In no particular order,

  • Swapping the Engine Out of a Moving Racing Car

  • State Machine Replication

  • Clock synchronization

  • Multicast and the markets

  • Build systems

EDIT: remembered a few other fun things I had stumbled upon recently, How We Built r/Place which is a good example of a small concrete project that has non-trivial scalability requirements, as well as Google's Maglev: A Fast and Reliable Software Network Load Balancer.
