  • It wouldn’t be a 30% higher electrical bill overall. It would be 30% more for whatever power you’re using for this specific device, which, if it’s ordinarily 10W while in sleep and an average 100W while in use, and you use it 50 hours per week, or 215 hours per month, that’s a baseline power usage of 21500 watt hours in use and 5050 watt hours from idle/sleep/suspend. Or a total of 26550 watt hours, or 26.5 kWh. At 20 cents per kWh, you’re talking about $5.30 per month in electricity for the computer. A 30% increase would be an extra $1.60 per month.






  • Spit out a random e-mail address and record which e-mail address was given to each IP.

    The author mentions it’s a violation of GDPR to record visitors’ IP addresses. I’m not sure that’s correct, but even so, it could be possible to make a custom encoding of literally every ipv4 address through some kind of lookup table with 256 entries, and just string together 4 of those random words to represent the entire 32-bit address space, such that “correct horse battery staple” corresponds to 192.168.1.100 or whatever.


  • Base64 encoding of a text representation of an IP address and date seems inefficient.

    There are 4 octets in a ipv4 address, where each octet is one of 2^8 possible integers. The entire 32-bit ipv4 address space should therefore be possible to encode in 6 characters in base64.

    Similarly, a timestamp with a precision/resolution in seconds can generally be represented by a 32-bit integer, at least up through 2038. So that can be represented by another 6 characters.

    Or, if you know you’re always going to be encoding these two numbers together, you can put together a 64-bit number and encode that in base64, in just 11 characters. Maybe even use some kind of custom timestamp format that uses fewer bits and counts from a more recent epoch, as an unsigned integer (since you’re not going to have site visitors from the past), and get that down to even fewer characters.

    That seems to run less risk of the email address getting cut off at some arbitrary length as it gets passed around.


  • The use of a “+” convention is just a convention popularized by Gmail and the other major providers. If you have your own domain, you should be able to do this with any arbitrary text schema, and encode some information in the address itself, especially if you don’t care about sending email from those aliases: set up your email service to have a catchall inbox that can further be filtered/forwarded based on other rules.

    It can be cumbersome but I could see it working at getting the information you’re looking for.


  • It’s not the chicken tax itself, even if it plays a role. It’s that the chicken tax makes it not economically feasible to try to import light trucks, so they aren’t designed to U.S. emissions and safety regulations. And several U.S. regulations are, in my opinion, misguided, but that doesn’t really change the fact that an importer wouldn’t be able to comply with vehicles that weren’t engineered to those specifications.

    Meanwhile, the cars and trucks engineered to American safety and emissions regulations face the perverse incentive to get bigger. This article describes some of the overall issues but contains this interesting nugget:

    That’s a sensible recommendation. Except the 3,000-pound 2010 Ranger featured by IIHS has become the bigger and taller 2024 Ford Ranger, which weighs up to 5,325 pounds. Like so many US cars, the Ranger got supersized, a trend fed by a mix of consumer desires and government regulations that carved out gas efficiency loopholes for the trucks and SUVs that make up a swelling share of the US vehicle fleet.

    In a sense, the trend of people wanting kei trucks paradoxically comes from the same reason why they’re not street legal: they didn’t get bigger because they weren’t subject to U.S. regulations pushing trucks to get bigger, but the noncompliance with those regulations makes them impossible to import and register (at least until they’re 25 years old).


  • People in garbage trucks don’t experience the same magnitude of force in a crash of equal speed, even without crumple zones, for a few reasons:

    • Sheer mass of the garbage truck means that the same amount of momentum transfer results in less force to the humans inside. A garbage truck might weigh literally 20 times as much as a kei truck, which means that an abrupt collision will transfer 1/20 as much impulse to the passengers (as most of the force goes into changing the speed of the truck). Even collisions with still objects (trees, walls, poles) result in less force on the passengers, as a lot of the energy ends up deforming or disintegrating that stationary object as a crumple zone.
    • Driver/passenger height in a garbage truck is generally above where the collision/deformation occurs. The passenger compartment isn’t under as much crushing force in a garbage truck crash compared to a kei truck at normal human height.
    • The height of a garbage truck gives a lot more physical structure to dissipate the forces in a crash.

    So the exact same shape/proportions of vehicle can be vastly different safety when large versus small.

    I’ve never really liked “children” in the sense of the age group, but I know a bunch of people who have really great, meaningful relationships between adult children and their parents, so I wanted adult children in my late middle ages and retirement ages.

    Now, with my own children, I primarily see them as future adults who I get to watch develop into cool people.

    Nothing’s been done about it since then.

    Research has gone into safer replacements. Many companies have been switching to BPA-free formulas, most notably CVS (notorious for sheer area of thermal paper receipts) that went BPA/BPS free in 2019. Some governments have banned BPA thermal paper, and others, including the EU, have set limits. BPA has been getting phased out because of these studies.

    Nothing will be done about it now.

    Well no, this organization is lining up to try to replicate the success with getting BPA out of thermal paper by trying to get BPS replaced, too.

    Here’s a study of Switzerland. Between 2014 and 2019, the incidence of BPA thermal paper went from 81% down to around 50%, and then after the ban it went to around 10%. BPS has seen some backsliding, and has increased from 3.1% to 19.1%. Still, that’s a significant reduction in the past decade of papers that use either BPA or BPS.

    People are doing the work. There’s no reason to sit around and do nothing and complain that others are doing nothing, too.




  • Can you please not use that term “Lazy Susan”? It’s got racist and sexist connotations, and I’d really prefer you just not call it that.

    Who’s that racist towards? Susans? That’s crazy. Where’d you get that?

    Okay. I would just like you to not use the term.

    You’re right. You know what? It should be…

    We should definitely start using the Ambitious Susan.

    Yes, yes. Please spin the Indefatigable Susan.

    Oh, can we have the Multifaceted Susan my way, please?

    Yeah, spin the Industrious Susan.

    Ooh, can you spin Ambidextrous Susan, please.


  • Dietary cholesterol has very little to do with health effects, but you swing too far in the other direction by claiming it’s “almost all genetics.” Plenty of environmental factors that can affect blood cholesterol (or more relevant to health, VLDL and LDL cholesterol), including diet.

    A big motivator behind the banning or restriction of trans fats in most countries is the clear link between trans fat consumption and cardiovascular disease, including a direct causal link to raising LDL (aka “bad cholesterol” and lowering HDL (aka “good cholesterol”).

    Some moderate physical activity has also been shown to significantly improve things like blood lipid profiles, at least compared to totally sedentary lifestyles.

    And genetics can affect how much of an effect these environmental or lifestyle factors actually change blood lipids, and in turn how much those stats correlate or cause actual cardiovascular disease, but diet and exercise are still important for almost everyone regardless of genetics.
