Who reads this anyway? Nobody, that’s who. I could write just about anything here, and it wouldn’t make a difference. As a matter of fact, I’m kinda curious to find out how much text can you dump in here. If you’re like really verbose, you could go on and on about any pointless…[no more than this]

  • The idea of modern medicine is to sell chemical compounds that actually have an effect. It’s a philosophical and ethical thing. All products have a unique psychological effect that gets intertwined with their biochemical effect. If you can’t study them individually, it’s impossible to tell if the biochemical effect even exists at all. If your medicine relies heavily, or even entirely, on the psychological side, it’s no different than homeopathy. The idea of modern medicine is to be better than the old stuff that preceded it.

    I prefer to think of this as an equation like this: Pm+Bm=Pp+Bp

    Pm=psychological effect, medicine

    Bm=biochemical effect, medicine

    Pp=psychological effect, placebo = surprisingly big

    Bp=biochemical effect, placebo = 0

    If these sides are equivalent, the medicine is just as effective as placebo. If the medicine side is bigger, you’ll want to know how much of it comes from the P and B terms. In order to figure that out, you would need to know some values. Normally, you can just assume that Pm=Pp, but if you can’t assume that, it you’re left with two unknowns in that equation. In this case, you really can’t assume them to be equal, which means that your data won’t allow you to figure out how much of the total effect comes from psychological and biochemical effects. It could be 50/50, 10/90, who knows. That sort of uncertainty is a serious problem, because of the philosophical and ethical side of developing medicine.


  • Statistical tests are very picky. They have been designed by mathematicians in a mathematical ideal vacuum void of all reality. The method works in those ideal conditions, but when you take that method and apply it in messy reality where everything is flawed, you may run into some trouble. In simple cases, it’s easy to abide by the assumptions of the statistical test, but as your experiment gets more and more complicated, there are more and more potholes for you to dodge. Best case scenario is, your messy data is just barely clean enough that you can be reasonably sure the statistical test still works well enough and you can sort of trust the result up to a certain point.

    However, when you know for a fact that some of the underlying assumptions of the statistical test are clearly being violated, all bets are off. Sure, you get a result, but who in their right mind would ever trust that result?

    If the test says that the medicine is works, there’s clearly financial incentive to believe it and start selling those pills. If it says that the medicine is no better than placebo, there’s similar incentive to reject the test result and demand more experiments. Most of that debate goes out the window if you can be reasonably sure that the data is good enough and the result of your statistical test is reliable enough.


  • Yeah, that’s the thing with placebo. It’s surprisingly effective, and separating the psychological effect from actual chemistry can be very tricky. If most participants can correctly identify if they’re bing fed the real drug or a placebo, it makes it impossible to figure out how much each effect contributes to the end result. Ideally, you would only use effective medicine that does not need the placebo effect to actually work.

    Imagine, if all medicine had lots of placebo effect in them. How would you treat patients who are in a coma or otherwise unconscious?











  • If you’re already an admin at work, you might not want to do any system administration at home. Well, until you find out that Microsoft is making some obnoxious decisions on your behalf, that’s when you suddenly find the motivation to do some research and tweak a bunch of settings. Situations like that will also lead to frustrating moments when you find out that your hands are tied, and you end up looking for workarounds. Spoiler: It doesn’t get any nicer after that.

    On the other hand, if you’re running a system that requires you to take responsibility, a lazy admin will end up in frustrating situations too. It’s not that simple to balance these things. You need to know what your priorities are and what kind of sacrifices you’re willing to make.


  • As a lazy Arch user, I can tell you that there will be frustrating moments, but not that many. Mostly you’ll be fine, but be prepared for minor annoyances.

    Features

    If you didn’t install it, it’s not on the system. That’s good for a minimalistic system, but frustrating for a lazy admin. Once you’ve ironed out all the issues you encounter during the first few months, the system should be pretty solid and worry free. However, once you encounter a new situation, you have to do your research, and install (and maybe even configure) that one missing thing. Later down the line, this becomes increasingly rare, but never disappears completely, so be prepared for minor annoyances like this.

    Interventions

    Before updating, check the official site for big news. Some rare updates require intervention, so you should know what you’re doing before updating your system. Usually it’s totally fine, and you can run the update command blind folded. It’s definitely not recommended, but it’s not going to destroy a simple installation any time soon. If you do complex stuff with your system, the updates become more frustrating. However, once you break your grub this way, you’ll learn to read those notes before updating. These things don’t happen often, but once a special update like that does roll out, you’re going to find it frustrating. Could take a few years, so you don’t really need to worry about it today. Just know what you’re getting into.

    Updating takes a while

    I update roughly once a week, but occasionally only once a month. Maybe there’s something wrong with my connection or settings, but I get timeouts all the time. As a result, I ended up just using the no timeout option instead of actually doing my research and looking into this problem. Need to take that deep dive one weekend eventually. One month worth updates is also a lot of data to download, and I’m getting 0 kb/s for several minutes at a time, so it takes even longer. A lazy admin suffers from annoyances like these. Be prepared for something similar to happen to your system sooner or later. Probably takes only 30 minutes of reading and two commands to fix, but I’ll get around to it another day. Before anyone asks, yes, I’m using a list of the fastest servers, and no, I haven’t updated that list in months.

    I still have Arch on my main laptop, but recently I replaced the Fedora of my HTPC with Debian. I just can’t be bothered to spend a minute on system maintenance, so Debian is better suited for that purpose. I’m still going to stick with Arch for reasons I don’t even fully understand. Probably just sunk cost fallacy at this stage…

    Just found some LG business TVs/displays/signage that actually run Tizen. Remember that cool Linux distro that was supposed to take over the mobile world nearly 15 years ago? Well, turns out, it didn’t, but it didn’t it die completely either.

    Hopefully those panels are a bit more hackable or more privacy oriented.
