  • It’s not that we don’t use mode, there are definitely times mode is used. It’s just that mean (and median as well) contain a lot more useful information about distributions that we often care about. For a normal distribution mean, median, and mode should all be identical. So why do we use mean? Because mathematically, the mean is what underpins the formula for the normal distribution, not median or mode, and when you’re talking about doing math with normal distributions mean is the thing to talk about (along with standard deviation).

    We use median a lot too, you probably just don’t hear it called median very often. The median is useful in non-normal distributions, and it defines the 50th percentile, so along with the 25%-ile and 75%-ile you’ve got your quartile distributions. We use these all the time to talk about grades in schools, or when we talk about home prices distributions in a given area, or salaries within a given field.

    We use mode too, again just by a different name most of the time. Any time you’ve asked “what’s the most common blank” you’re basically asking for a mode. When we talk about “average” income in a country, we’re usually actually talking about median or mode. Favorite animal? Answered as a mode.

    You have to use the right statistical tool for your question: unfortunately English doesn’t do a good job of conveying this without math jargon.



  • I mean if the only way they’re gonna have jobs is through predatory hiring practices that could leave them fired and without severance, then yeah. Because if the company is planning on hiring these younger workers for the long-haul, then this shouldn’t be a significant change. I think overall national policy should discourage unnecessary high-turnover and predatory hiring. I’m sure there will be situations this is still unavoidable, but that doesn’t mean we have to endorse it by way of law/policy.


  • I’m going to digress from the economics a tad and focus on the ethics of this. I feel like companies should be on the hook for this. You should invest in capital (including human labor) based on your confidence in its expected return. Companies should not be able to hire a myriad of workers for funzies and not have to meaningfully consider if that person will be necessary in 6 months. If it is a legitimate business venture, then the cost of potential severance for new hires should be folded into the economics of the decision to pursue that venture. Larger severance pay/worker protections encourage employers to not utilize exploitative hiring practices.


  • It depends on the half life of the element in question. The most comparable concrete thing we can compare this to with real numbers because we know it works is an RTG. RTGs are solid-state generators, but people could colloquially refer to them as “batteries” and not be terribly wrong. They take a quantity of a radioactive material and allow it to decay, using the heat given off to establish a thermal gradient which is then converted to electricity via thermocouples. Most of these are “fueled” with Pu-238 (at least the ones for spacecraft), which has a half life of 87.7 years. That means in 87.7 years, if you started with 4kg of Pu when you built it, you’d have only 2kg of Plutonium left. If the Pu decayed only into stable isotopes (it doesn’t) then your radioactive emissions/decay would also be exactly halved at this time. If the electrical system is perfectly efficient this would also halve the electrical power produced.

    I provide this all as background because to answer your question you have to know three key factors about the device to determine the lifetime of the battery. The half-life of the isotope used, the minimum electrical requirements of the device you’re powering, and the amount of radioactive material in the initial battery. The battery’s lifetime is determined by when decay will decrease the ongoing energy output below the minimum current and voltage requirements needed by the battery. The longer the half life of the isotope, the slower this decrease is and the less initial overpowering that is required.

    Ex. If you use an isotope with a 12.5 year half life for a “50-year” battery, you would need to start with 8 times the material needed for your minimum power output requirements. If you use an isotope with a 200 year half life, you only need 19% more starting mass than you minimum requirement. The first battery will produce 8x the power at the very beginning, while the second will only produce 18% more.





  • All remote based typing is awful, T9 included. I can’t speak for everyone, but I can type with swipe gestures on a virtual keyboard via remote faster than I can input T9 text. I’m unaware of any stock remote for a device with a full keyboard. I would argue Apple has text entry perfected at least as well as any other major manufacturer. You have virtual keyboard entry, solid voice-to-text, and it can be configured to push a notification to your iOS device when you enter a search bar which will auto-open to the remote app and pull up the keyboard. Because of this feature passwords can also be autofilled from Keychain to make logins easier.

    You may personally prefer T9, but I’ve never seen anyone in the last decade input anything into a TV via T9. And you’re asking why it doesn’t have voice input, when it does. You admit to having never used an Apple TV yourself. I hate the idea of app-only interfaces features, but this isn’t a case like that. Maybe you should understand the features of a product before you call it “fucking stupid”.



  • You’ll have to strike a balance between security and ease. Your two major options are reverse proxy and VPN (Tailscale is one option for VPN)

    For reverse proxy, you functionally open the app to the internet. Anyone with the correct web address can access the login page. This is inherently less secure than VPN, but not irresponsibly so. Beyond the reverse proxy itself, you’ll also have to learn how to configure an HTTPS certificate to increase security since it will be open to the internet.

    For VPN, every user you want to be able to access the service has to be tied into the VPN and have the VPN running throughout their access. Tailscale is arguably the easiest way to configure a VPN right now, as you won’t have to manually deal with VPN configuration files for every device. VPN use will functionally make it like you’re on your home network. VPN access to your network should not be given to tons of people if at all possible.


  • No, in fact I believe very heavily in evaluating primary literature to re-evaluate decades-old dogma within medicine. I regularly disagree with my professors when they present outdated information in lecture. I have no income right now, and I have forgone substantial amounts of income by pursuing medical school instead of continuing to practice pharmacy. I’m not in this for the money.

    If you would be so kind, I would love to know what evidence you present in contrary to the decades of peer-reviewed cohort, case-control, and RCT data which validate psychiatry as an effective field for managing psychiatric illness. I’d be happy to discuss any scientific data you have that I haven’t seen, and would be happy to change my opinion if it is data-driven.

    I can appreciate your skepticism towards medicine and psychiatry, but if you can’t defend your position with anything but accusations and conspiracy, then I don’t think we have much else to discuss.



  • You know I felt this way for years. I felt that way through psychopharmacology in pharmacy school, and I felt that way during our psychiatry and behavior lectures in medical school. I felt like psychiatry was minimizing behavior to these boxes was far too reductionist. Then I spent a month in an inpatient psychiatry facility as a third year medical student.

    While I completely agree that each individual is unique and people are more than their diagnosis, you’d be absolutely shocked by just how similar patients’ overall stories, maladaptive coping mechanisms, and behaviors are within the same psychiatric illness. I can spot mania from a doorway, and it takes less than five minutes to have a high suspicion for borderline personality disorder. These classifications aren’t some arbitrary grouping of symptoms: they’re an attempt to create standard criteria for a relatively well preserved set of phenotypic behaviors. The hard part is understanding pathology vs culturally appropriate behavior in cultures you don’t belong, and differentiating within illness spectra (Bipolar I vs II; schizophrenia vs bipolar disorder with psychotic features vs schizoaffective)


  • I self host a lot of shit, but after almost a year of using Obsidian I finally paid for their sync feature for one reason: iCloud sync to iOS is painfully slow.

    I was sometimes waiting 30-45 seconds to jot down a note just waiting on the app to open with iCloud sync as my backend. Now, with Obsidian sync, the app is ready-to-go in seconds.

    Now if you’re only going to be using on desktop, I would definitely consider a git-repository based sync, but if you’re gonna use mobile I’d recommend you at least consider Obsidian Sync



  • Yes, but most DRM has been circumvented in one way or another. DRM primarily continues to keep law-abiding citizens from easily acquiring a copy of media they rightfully own as opposed to preventing piracy.

    Though if institutions insist on utilizing DRM for prevention of privacy, I do think that DRM should be built to fail after a meaningful timeframe, at worst the expiry of the copyright for the material. Unfortunately many pieces of media, particularly video games, are abandoned and unsupported long before their copywriter expires. Abandonware in general is not well handled by modern copywrite law.


  • I think the point is more so why are digital purchased DRM’ed and prohibited from local storage in so many ways. The historical argument is “well you’re not buying it, you’re buying a license to use it for as long as we wish to provide it”, but why does it necessarily need to be that way. And more generally, from the standpoint of artistic/media preservation, as BluRay releases continue to decrease and console video game releases become continually more digital-only, these non-archivable or locked-without-server-license-validation media results in IP that at some point in time, this media could be permanently lost.

    Personally, I feel this is unacceptable. The media we consume forms a huge portion of our culture, and is just as much an example of artistic expression as painting. While I thoroughly believe artists/companies should be able to charge for these properties, I do not believe that when it is no longer profitable for them to support the system, that these pieces of media should simply be discarded with no method for future recovery and preservation.
