    Forgive my self-indulgence for a second… I walked into Heffers in Cambridge, and guess what I found there on the shelf? 😎

    New evil plan to confuse the hell out of everybody: claim that git is a blockchain, due to each using Merkle trees.

    Super interesting read on how a libc upgrade can silently corrupt your Postgres indexes! Tl;dr: libc doesn't guarantee collation order across versions, upgrade libc -> existing indexes might be in wrong order. PG 10+ can use ICU for collations instead.

    And as a nice extra, by joining the ACM you also promise to follow its code of ethics: — and having more people in computing think about the ethical consequences of their work is surely a good thing.

    Pro tip: instead of paying $399/year for books online (frankly outrageous), you can get ACM professional membership for $99/year, which includes Safari access.

    Moreover, if you're in the UK (and perhaps other countries), ACM membership is tax deductible

    Someone should do a study of the most often-used textbooks to prop up a monitor or laptop. CLRS seems like a popular choice in this thread

    Thread on making open source work financially and mentally sustainable.

    I might help non-paying users, because they found interesting bugs, or there's money left over from paying users, or because I'm feeling nice, but I don't have to—my time is valuable, and I don't owe random consumers of my work anything.

    But ultimately, beyond that, we're nitpicking over band-aids. The proper solution is a dead simple economic one. Maybe open source dependency management wouldn't be such a clusterfuck if we paid OSS devs for their work properly.

    I personally reviewed every word of the German translation, and I'm very pleased with the result. Unfortunately I don't have the language skills to review the other translations.
