  • Out past the planets is the heliopause, the final boundary between the solar system and interstellar space. Voyager discovered it, but other probes have confirmed it. The radiation and particles emitted by the sun create a pressurized bubble around it, where plasma (energized particles, mostly hydrogen) is much denser than past the heliopause. Cosmic rays are more prevalent outside it.

    I’ve heard it compared to the empty zone around where a sink faucet first hits, creating a little “wall” of water around it as the splashing water pushes back the standing water.

    “Empty” space is anything but. There’s tons of particles and energy flying though it, just not as dense.



  • But then I decided, I wrote my own solution, a thing of 1,600 lines of code, which is, yeah, it’s like thousands of times less than the competition.

    And it works. It’s very popular. … I got 100 emails from people saying that it’s so nice that someone wrote a small piece of software that is robust, does not have dependencies, you know how it works.

    But the depressing thing is, some of the security people in the field, they thought it was a lovely challenge to audit my 1,600 lines of code. And they were very welcome to do that, of course. And they found three major vulnerabilities in there.

    He makes a ton of excellent points, but the succinct impact of this little example really hit for me. As someone who often rewrites things so that I can both understand and fully trust in what I’m depending on, it’s always good to be reminded that you literally can’t write 500 lines of code without a good chance of introducing a major vulnerability.

    The tech stack is so dizzyingly high today, and with so many interlocking parts, it continually amazes me that anything at all functions even in the absence of hostile actors.


  • I’m convinced it’s the whole B-2-B software world at this point. The shit starts at MS (or any of the FAANGS) and rolls downhill to everyone else.

    We’re working on a huge Dynamics 365 thing at work, and one of the third parties we use for automated testing is just… the product seems barebones, is clearly built on top of open source automated testing tool, and is riddled with indicators that barely anyone works there, from the AI help bot to the “submit a ticket and we’ll assign it eventually” approach to all other interactions.

    I looked them up on Linked In and 12 people work there. 8 of them have C-suite or VP titles, and 4 of them are interns from a local university. This is the state of all modern tech: a board room full of investors, a website, and a product barely glued together from FOSS parts by interns. If you wonder why everything feels like a scam now it’s because it is.



  • Software devs for a long time would discuss “green field” development, which is a metaphor from constructing a building in an empty field: you start from nothing, and build all new. Most software devs prefer to write new code rather than try to learn the quirks and nuances of a large, already-existing pile of code, so “green field” is considered both desirable and often practically unattainable.

    “Blue sky” is a similar concept but loftier. It isn’t just that you have an empty field waiting for you, you’ve got the infitie expanse of the clear blue sky: endless possibilities, unlimited creativity, etc. “Blue sky development” as a metaphor I think comes from designers, product managers, and other software-dev adjacent fields. It means thinking of ideas that are out of the box and unconstrained by historical limits.

    That’s why everything is named that: execs and marketers love that kind of hollow promise. That anything is possible even though actually they’re almost always just clones of existing things whose greatest innovation is to loudly proclaim how new and innovative you are.
