   I love the symmetry of capacitors and inductors. It's just so elegant. Inductors: store energy in a magnetic field, pass DC, block AC Capacitors: store energy in an electric field, pass AC, block DC I'm omitting a bu

   I have fond memories too, we used to follow "The little Schemer" for Scheme, but we had a PC lab running Windows.

   The usual argument is that the Jacquard's loom inspired Herman Hollerith’s tabulating machine, used to tally the 1890 census, and became the basis of IBM. Essentially, the speedups in textiles, inspired a speedup in computing (tabulati

   I used to do that, I had a sort of IDE that launched a local server, bound to localhost. The launching process would send a random password through stdin to the child after launch, and the child would use that to authenticate the further RP

   Like most people, I’ve had my identity stolen once or twice in my life. Huh? It's not as common. I don't think I've been victim of it ever, unless it's way more common in some other countries? Much less on a pr

   I just keep most of them disabled. I only keep mentions in Slack, DMs in Whatsapp, and that's about it. I actively poll anything else.

   GitHub cannot see enterprise repos. Those are purposely kept on-prem.

   It feels like this would backfire. I mean, UV light is carcinogenic, and environments that are way too clean, are fine for surgery or manufacturing semiconductors, but for most humans (specially children) they can be counter-productive. The

    But even a toy compiler would be useful to inspire someone else to pick up the concepts. It doesn't have to be production grade, just as a communication tool.

    I kind of agree, as a counterexample I think about Scala. Martin Odersky I think influenced many other mainstream languages (including Java) that picked up functional concepts and integrated them with OOP. Pure research is fine, but being r

    How do you calibrate? I mean, the sensitivity of the microphones varies a lot. Legal proof needs a metrological chain of trust.

    One thing that helps a lot is somewhat isolated compilation units. That means that most of the rest of the project is largely irrelevant besides some basic type information. If your parsing context is small enough, you may be able to run a

    8M kW? Isn't that 8GW? That's more than 6 DeLorean Time Machines worth of power! (~6.6 at 1.21 gigawatts per flux capacitor)

    I get the joke, but I disagree. It mixed hardware with software in a weird way. Macs are as much about the hardware than the software, and the OS is just another Unix variant. Much closer to Linux/BSD than Windows. I like tech (no fear

    I haven't had any issues with NVidia's on the latest machine I built (like nothing). It's just an optional update whenever I remember to check for one.

    It's not the "can't" necessarily, it's about friction, I could get it working on linux, but then I'd probably be just fiddling with settings way longer than I do today. Current Windows gaming experience is almo

    For me it always felt weird, it surprises me that it survived on-by-default for this long. It's one of those remnants of ancient UX, like focus on hover.

    Windows is not for doing serious stuff anymore, the only remaining use case for me is a gaming PC (if you turn off all the nags, it's pretty decent). I work on a Mac, I run servers on Linux, I game on Windows.

    Isn't this a gimmick? (I mean, it's still impressive) I don't want natural language, way too ambiguous and too much typing (or worse, talking). 90% of the things I do repeat frequently. Brevity is key for me. I like formal sy

    Information work has always been weird (software, writing, composing music, etc.) Software is not a thing in the same sense a chair is a thing, making copies cost nothing and that has two effects: you can build much more complex things, cop

    Seriously? UX in Linux is awful, there's no single desktop metaphor. You have hundreds of distros each with their quirks. There is no "Linux" other than the kernel. There's a lot more consistency in the Apple ecosystem.

    The bug is in the positional number system. It would make much more sense to add digits to the right and left-align everything. Hex dumps would make sense, columns in spreadsheets would be left aligned always, and so on. But we're too

    I wonder if hurting the consumer space won't end up crippling the AI hyperscalers ambitions? I mean, the lack of affordable consumer hardware may end up further reducing the need for AI. On the other hand, it may end up shifting worklo

    If you're skilled enough, sometimes you can even force the culture to change. It can be painful and not all battles are worth it, but it's doable.
