  1. AI Flame Graphs 2025-01-20

    AI developers think about their bit of code, but with AI Flame Graphs they can now see the entire stack for the first time, including the HW, and many layers they don't usually think about or don't know about. It basically looks like a pile of gibberish with their code only a small part of the flame graph.

    This reaction is similar to people's first experiences with CPU flame graphs, which show parts of the system that developers and engineers typically don't work on, such as runtime internals, system libraries, and kernel internals.

  2. source-file [-Fnqv] [-t target-pane] path ...
                  (alias: source)
            Execute commands from one or more files specified by path
            (which may be glob(7) patterns).  If -F is present, then
            path is expanded as a format.  If -q is given, no error
            will be returned if path does not exist.  With -n, the
            file is parsed but no commands are executed.  -v shows
            the parsed commands and line numbers if possible.
    
  3. Repology monitors a huge number of package repositories and other sources comparing packages versions across them and gathering other information. Repology shows you in which repositories a given project is packaged, which version is the latest and which needs updating, who maintains the package, and other related information.

  4. The Web Authentication API (also known as WebAuthn) is a specification written by the W3C and FIDO, with the participation of Google, Mozilla, Microsoft, Yubico, and others. The API allows servers to register and authenticate users using public key cryptography instead of a password.

  5. "Cache is king. And if your cache is cut, you're going to feel it."

    "Some providers now have something called Metal-as-a-Service, which I really think ought to mean that an '80s metal band shows up at your office, plays a gig, smashes the furniture, and urinates on the carpet."
