  • From an old edition of the Pilot’s Handbook of Aeronautical Knowledge:

    An airplane’s tire will hydroplane at a speed in knots equal to 9 times the square root of the tire pressure in PSI. So if your tires are inflated to 36 PSI, sq.rt 36 = 6 * 9 = 54 knots. If there is standing water on the runway, you will have no braking authority or steering control from the wheels, you will have to maintain control of the aircraft with the flight controls, and you cannot rely on short field stopping figures from the POH if it requires applying brakes above 54 knots.

    I got that out of the 2003 edition; I don’t know if it’s in the current issue.


  • I had a nightmare once made mostly or entirely out of assets from Ocarina of Time.

    I found myself in an underground room of some kind, just a large space made out of that brown dirt wall texture. There was no entrance or exit, the room was maybe the size of a large classroom or two, maybe 30x40 feet? Along one wall was a low rise, with the light grey stone wall texture behind it, two braziers providing the only light in the space, and a kind of gallows/gantry thing made out of those large wooden beams you see Beneath The Well. One upright member supporting a horizontal swingarm, and from the end of the swing arm dangled a noose.

    Standing beneath the noose was a tall, thin figure. Thinking about it now I picture it as a ReDead enemy but I don’t think that’s what it actually looked like. It made no sounds at all. It walked like a ReDead does though; that slow labored trudge. It started trudging toward me, and as it did, the gantry moved to keep the noose hangling about a foot directly over its head, making the noise from the Castle Town draw bridge as it moved.

    It followed me around this room for a bit, I couldn’t move very fast, like my body wouldn’t respond right. I tried to say something but I couldn’t summon up any power.

    I woke up in a cold sweat with my girlfriend asking me what was wrong. Did I mention I was 27 years old at the time?

    The novelty of my brain using N64 graphics for this, along with the weirdness of the noose hanging over the figure and not actually around his neck, burned it into my memory.


    I’ll also never forget the first lucid dream I had. I was on my grandparents’ back deck, talking to several members of my family. My grandmother’s dog Ginger started barking over us, as she constantly. I started to say some smartass line to the dog, starting with “Ginger, you shouldn’t bark because…” and then a thought occurred to me. “…Because you’re dead…we put you down last year, and dead dogs don’t…bark I must be dreaming.”

    The dog and the people disappeared. Just…despawned. Everything got less vivid and my peripheral vision disappeared. I could see what I was directly looking at, or a blank beige color. I walked around the yard for a minute in a perfectly familiar and yet empty world, everything simultaneously had a kind of dark “before an afternoon thunderstorm” kind of look and that blank beige color, and after a minute or two I woke up.

    I hadn’t heard of lucid dreaming before this, and in fact not until a couple years after the fact. I spent a couple years really interested in the subject when I did, and managed it a couple more times. Some people talk about having “control” of the dream, for me, I usually realize I’m dreaming, it immediately starts to fade, and I’m able to just walk around and look at stuff for a little bit before I wake up.



  • That’s what a lot of the upgrades boil down to, yeah. Air tanks increase endurance, fins and seaglide increase movement speed, rebreather eliminates an endurance draining effect at depth, seabases and submarines allow you to start your dive from greater than zero depth. Pretty much all of that boils down to “dives to this depth are now practicable.”

    Other than that, the knife allows you to harvest plate coral for making computer chips, kelp for making fabric, and seeds for plants. The scanner is required to obtain the blueprints for several other required buildables. The mobile vehicle bay is required to build the Cyclops. The Cyclops is required to make the shield module. A radiation suit…I think speedrunners don’t use it and just tank the damage with medkits, but I consider it a requirement.

    There is one straight-up key you have to craft; there are several others for required or optional doors but you only have to craft one to complete the game and two to unlock all doors.

    There’s a tool that is like Half-Life 2’s gravity gun, which can be used to move heavy obstacles out of paths, but it’s never outright required for anything. I usually don’t bother with it.

    The laser cutter is required, You have to cut through one of two doors in the Aurora to gain access to the Captain’s Cabin.







  • Somewhere in middle school they give up on the “if you have two apples and buy two more apples you have four apples” or “if you have 3 pizzas cut into 8 slices each and your family eats 13 slices how many pizzas do you have left?” and they start trying to teach 11 year olds by making them memorize proofs and phrases like the transitive property of equality.

    To a lot of high schools and colleges, the aesthetic of academia is much more important than students actually learning anything useful, so they teach math class with a chalkboard full of squiggles rather than any kind of practical approach.

    From Algebra class on up, it’s taught as a rules following exercise. “Okay, now we do this, and then who knows what we do next?” And it is amazing how many of them are set up as trick questions, how often out of the infinite span of numbers there’s often one right answer and one wrong answer. “How many of you got five? Well you’re wrong, it’s negative 3.”

    Meanwhile, I was learning how to fly. In flight school, you learn how to navigate by dead reckoning. I want to fly this course on the map, which is x distance and x degrees from true north as measured from the chart. Given a weather brief and the performance characteristics of the plane from the pilot’s operating handbook, calculate: true airspeed given indicated airspeed, altitude and temperature wind correction angle, given true course, true airspeed, wind direction and wind speed ground speed, given true course, true airspeed, wind direction and wind speed true heading given true course and wind correction angle magnetic heading given true heading and local magnetic variation time aloft given distance to travel and ground speed fuel consumed given time aloft and fuel consumption

    The tool you’re taught to use to calculate all of this looks like this:

    It’s basically a circular slide rule, that has a vector plotter on the back. The trigonometry is done by accurately drawing and measuring the triangle, the ratio problems (anything “per hour”) is done by rubbing a couple of logarithms together, and you’re on your own for the addition and subtraction. Ever used a slide rule? They don’t keep track of the decimal point for you. So you have to do these built-in sanity checks, like “Wait, no, the plane doesn’t even hold 70 gallons of gas, there’s no way I’ll burn that much in ten minutes.”

    I learned how to do that before I took physics class, and surprised my physics teacher that I knew how to do “boat crossing a river” problems with a weird piece of cardboard. Later on, when I was teaching flight school, I taught that procedure to “It’s been 30 years since math class” boomers and “Trigonometry is next semester” teenagers. They all picked up on it without much problem, because “the wind is blowing you to the right” is a real thing they’ve felt in their own asses by now.




  • Will my ability to play games be significantly affected compared to Windows?

    Depends on the games you play. Because of things like DOSBOX and Wine, it is sometimes easier to get DOS and early Windows games running on Linux than it is Windows. Valve’s Proton compatibility layer allows games written for Windows to Just WorkTM on Linux. My diet of nerdy factory building games and indie titles works perfectly well in Linux, my cousin who plays Bethesda and EA games ran into more irritations. The major compatibility barrier is competitive online multiplayer and anti-cheat systems. Many developers intentionally exclude Linux compatibility. The game runs fine, but you’ll get banned for doing it.

    Can I mod games as freely and as easily as I do on Windows?

    Probably, depends on the game. I didn’t have much of a problem modding Kerbal Space Program or Satisfactory, the communities offered mod managers that worked perfectly well.

    If a program has no Linux version, is it unusable, or are there workarounds?

    My suggestion would be to go full native if you can. Like, Adobe Photoshop isn’t available on Linux, so instead of trying to make it work, give GIMP or Krita or one of several others a try. Increasingly, things like Slack are Electron apps, which basically run as a glorified web browser, so they’re fairly easy to port to Linux and it’s becoming increasingly typical to upload them to Flathub.

    Can Linux run programs that rely on frameworks like .NET or other Windows-specific libraries?

    Yes, through a compatibility program called Wine, which I’ve already mentioned. Though again I would recommend going for native applications than trying to use Windows software on Linux.

    How do OS updates work in Linux? Is there a “Linux Update” program like what Windows has?

    Short answer: Better than Windows does.

    Different Linux distros will handle this slightly differently, but generally speaking your system will come with a thing called a package manager. It’s basically an app store but everything in there is free. The package manager handles updates for the OS itself as well as the software you’ve installed, up to and including updating to the next version of the OS if applicable. In fact as I write this, my computer is asking if I want to upgrade to Fedora 42.

    It’s also not as onerous as Windows updates; most of the time it’ll update software, you can use the rest of the system while that’s happening, and it’ll finish and it’s fine. Sometimes it’ll say “must restart computer for changes to take effect” but it won’t force or nag you to do that. You can come to a stopping point in your work, then do a normal restart. None of that “Updating your computer 1 of 7…” it just does a normal boot in a normal amount of time.

    How does digital security work on Linux? Is it more vulnerable due to being open source? Is there integrated antivirus software, or will I have to source that myself?

    Linux has a system of permissions, a bit like how Windows will sometimes ask you to run things as Administrator. Linux has had that concept longer than Windows has, Linux will call it the Root or SuperUser.

    Increasingly, sandboxed applications that run essentially in their own virtual machines are being used to limit what an application can access. Flatpak has a system of permissions not unlike Android, where you can say “No this app doesn’t need camera access.”

    We get a lot of security from having a package manager we actually use. Linux users aren’t in the habit of downloading random .exes from all over the internet. Software in the repos is vetted and signed. Don’t run code you don’t trust.

    Few Linux systems come with built-in antivirus software. Conventional wisdom is it isn’t needed. Antivirus software does exist for Linux, but it’s often to detect Windows malware in server traffic. For an end user desktop it’s not necessary.

    Are GPU drivers reliable on Linux?

    AMD publishes their drivers directly to the Linux kernel. My 7900GRE Just WorksTM. Nvidia tends to be a bit more of a pain in the neck. Your system will likely come with the open source Nouveau drivers, which will run but possibly not very well, and you’ll need to install proprietary drivers, which…the method you go about doing that varies from system to system.

    Now, I had a hell of a time with the hybrid graphics on my laptop, but I think that’s another story.

    Oh, yet another story: on my GTX-1080 in my previous computer, I started to have an issue with a new monitor I bought. Turns out the card needed a firmware update or it wouldn’t let the computer boot with a late model DisplayPort monitor attached. Not a driver update, a firmware update. Nvidia does not publish the tool to do that for use in Linux, so I ended up taking the GPU out and borrowing a Windows computer.

    Can Linux (in the case of a misconfiguration or serious failure) potentially damage hardware?

    I think I could use dd to wear out an NVMe SSD via excessive writing. But basically no. You’re not going to flip a switch in a settings menu and hear a bang from your case.

    And also, what distro might be best for me?

    I would recommend trying several. A few of my favorites over the years have been Mint Cinnamon, Fedora KDE and Ubuntu Mate.



  • I think I’ve done a reasonable job improving my dovetail jig.

    That 12 inch Porter Cable model; it has some problems with repeatability. The reference marks are quite wide and positioned in a way to give a lot of parallax error. There was no real way to quantify how far you’ve moved the template in and out, which meant it’s basically guaranteed to come out of alignment. So I took a knife to it. Scribed the alignment line around all the tines and put graduation marks on the brass thumb wheels. It’s a lot easier to be deliberate in adjusting this thing now.

    It still needs a few other things here and there, and I need to put those alignment marks on other templates. But it’s a start.




  • I forget why, but Picard and Riker are away, Data is in command with Worf as his first officer. Data wants to be analytical and consider all options, Worf wants to fire all phasers and die in glorious battle. Data comes to a decision and gives orders, and Worf says “Finally!”

    Data asks to see him in the ready room, and then dresses him down for talking back to him in front of the crew. They hash out what they expect the role of second in command is supposed to be, and with the military shit out of the way, Data then acknowledges that this dressing down may have damaged their friendship, and Worf replies that no, he was out of line so it was his fault, that he acknowledges that he was out of line and if we can overlook this incident he’d like to continue being friends.

    Stated problems, voiced objections, addrressed objections, no personal slights, no raised voices, actual accountability expected and accepted…manliest conversation ever filmed.



  • On my main desktop I’m using Fedora KDE. Arrived here by process of elimination.

    Linux Mint Cinnamon didn’t run particularly well with my hardware, I was looking for a distro with decent Wayland support so I could run my high refresh rate monitor properly. So that pretty much meant a switch to KDE. So who’s implementation of KDE?

    I’ve spent much of my time on the Ubuntu side of things, but Canonical has been pulling so much diet Microsoft shit that I’d rather not use any of the *buntus themselves, so Kubuntu is out. Neon? Kubuntu again. I’m not terribly interested in the forks of forks of forks of forks, I’ve been around long enough to go “Remember PeppermintOS? You don’t, okay.” So I’m looking for something fairly near the root of its tree.

    I’ve never really seen the appeal of Arch and every time I’ve tried running Manjaro it failed to function, so forget that. I don’t know shit about SuSe, that basically left Fedora. So here I am.
