  • I can’t prove it but I think there is a real sociolinguistic phenomenon where Americans are unusually obsessed with “safety through temperature”. Like they hear “fire = no germs” as children and somehow internalize that steaks should be somewhere between well done and burnt beyond recognition, and dishwashers should boil your plates like you’re sterilizing a hospital gown that’s been thrown up on by an Ebola patient.

    Soap, bitches. It works. Even at 40 °C (with modern detergent and washing cycles). Good thing too because I don’t want to know how y’all are having sex if you think boiling water is the only decent cleaning procedure for putting things in your mouth.


  • Technology Connections and Hank Green have been shouting this for a while, but that whole issue is way overblown. Some first gen EVs around 2010 had issues, but every major manufacturer since then has way exceeded expectations on battery lifetime thanks to advanced BMS and thermal controls. Car batteries don’t just rapidly degrade out of the blue, the tech has nothing in common with what’s in your phone. But public sentiment has not caught up because most people think Li-Ion = smartphone = dead after 2-5 years, so second hand EVs are way undervalued. Which is great for buyers.

    It’s not like you can’t easily total a second-hand ICE by mechanical failure. Just ask anyone who own(ed) a puretech engine. If you went by manufacturer recommendations, the fucking thing might just eat your timing belt one day and grenade itself. And there’s no way a full engine swap on a 5-10 year old economy car is economically viable.

    There’s always something that could go wrong when you buy a car. Unless you get comprehensive insurance and warranty, you need to accept the fact that losing the entire car to an accident, catastrophic mechanical failure, or theft is always a risk. If that’s too much anxiety to deal with, get a lease.

    If we’re going to be pedantic, let’s do it correctly.

    Even with the blinds shut, a space heater will emit a surprisingly large amount of radio waves (mine actually disrupts USB devices with a small EMP when it turns on, and anyone with an RTL-SDR can tell you those 50 Hz harmonics are rough). Some of those radio waves will penetrate the walls/blinds and a tiny fraction might escape the atmosphere and head off into space. From there some will find their way to interstellar space and potentially drift “forever” (well, until the heat death of the universe or whichever theory you subscribe to; I think at that point saying “the photon never got converted into heat energy” is a good enough approximation).


  • Speed limits are trickier than structural safety margins because of several factors:

    • In some areas, particularly remote areas, the process isn’t very well defined. Sometimes the speed limit will be set by one guy who just felt like that was fine. Doesn’t even have to be an engineer really.
    • Standards evolve over time (trending towards lower speed limits) but speed limits only change when a tragedy or major road renovation happens. Where I live there’s sometimes a 40 km/h spread on posted speed limits for similar roads depending on whether they were rebuilt last year or 50 years ago.
    • Car culture means drivers hold a ton of political power. There are a myriad of traffic devices that cannot be built not because of practical or financial constraints, only because they would “inconvenience drivers”. Lower speed limits are often one of those. People complain so the government backs down despite engineering recommendations.
    • A driver is always liable if they drive too fast for the conditions, not the traffic engineer. That goes to the previous point, with zero penalty for not sticking to the sensible engineering choice, political pressure easily wins out. Hard to argue against a work order when the person signing off on it cannot be sued for negligence.

    The upshot is speed limits in my local experience have a lot more to do with the municipality/region’s political climate than engineering standards and safety factors. Sometimes I feel like I could safely go 2x, sometimes the limit is 90 km/h on a two-way one lane road with 30 m of visibility where 30 km/h feels like I’m pushing it.




  • Assuming you like eating chicken, when is it wrong to pair chicken with vegetables? I made a vegetable-mushroom-chicken soup last week and it was delish. Whether chicken is or isn’t a vegetable is an academic concern, not a culinary one.

    Try putting mushrooms or chicken in the sangria however and you’ll be rightfully prosecuted for crimes against humanity.




  • THANK YOU.

    I migrated services from LXC to kubernetes. One of these services has been exhibiting concerning memory footprint issues. Everyone immediately went “REEEEEEEE KUBERNETES BAD EVERYTHING WAS FINE BEFORE WHAT IS ALL THIS ABSTRACTION >:(((((”.

    I just spent three months doing optimization work. For memory/resource leaks in that old C codebase. Kubernetes didn’t have fuck-all to do with any of those (which is obvious to literally anyone who has any clue how containerization works under the hood). The codebase just had very old-fashioned manual memory management leaks as well as a weird interaction between jemalloc and RHEL’s default kernel settings.

    The only reason I spent all that time optimizing and we aren’t just throwing more RAM at the problem? Due to incredible levels of incompetence business-side I’ll spare you the details of, our 30 day growth predictions have error bars so many orders of magnitude wide that we are stuck in a stupid loop of “won’t order hardware we probably won’t need but if we do get a best-case user influx the lead time on new hardware is too long to get you the RAM we need”. Basically the virtual price of RAM is super high because the suits keep pinky-promising that we’ll get a bunch of users soon but are also constantly wrong about that.


  • Being able to assign a nameserver per interface with a domain wildcard is a fucking godsend. I use it every day with a hook script because my job uses some private domains but I don’t want to send my entire DNS history through the VPN. Now ~job.com goes to tun0 and that’s the end of it.

    systemd-resolved is not perfect but with libnss’s overly rigid nature the only alternative for my use-case would be to recreate similar functionality to resolved with dnsmasq – which is just objectively worse especially when you want to use DHCP sometimes but not always. Why reinvent the wheel? resolved does its job and does it well. I had some issues with it a few years ago but have been using it for the past couple years without complaint.





  • It’s not even about predictions or estimations - everything’s so many years late everyone stopped counting. They just… don’t seem to understand “scoping”? The pitch is “ultra-realistic life-size universe sandbox simulation” and they keep hitting walls because they’re using tech that’s completely inadequate for the task at hand but they won’t let that deter them. They’ve probably reimplemented every subsystem of the Crysis 3 engine a dozen times by now, and it’s still not anywhere near capable of achieving even a tenth of their ambitions. Fuck, they just very recently got their server meshing thing barely working after like a decade of development (at the cost of rewriting everything again of course).

    It’s like watching a team raising billions to build the Burj Khalifa but all they have is a bunch of dry sand and some spoons. Deadlines aren’t really the issue.



  • It’s like every other media industry. The monoculture is dying. Everyone’s who’s “about it” is into niche subcultures and micro-celebrities you’ll probably never hear of.

    There was a weird period of time from the mid-20th through the early 21st century where radio and TV had very strongly concentrated media production which made up most people’s media consumption.
    For the last 15 years or so the tools of professional-looking media production for mass consumption have been available to anyone with a few hundred bucks to spare.

    In some ways it’s a communist utopia. The means of production have been commodified so much virtually anyone can afford them. However capitalists have moved on from owning the means of production to owning the means of distribution (the platforms).


  • this is all about something Eve did, not something that Eve is.

    Except the first sentence applies to all mothers who ever were. It is literally about what women are. Mr Omnipotent couldn’t figure out how to punish Eve without punishing all her daughters throughout all eternity? The mental acrobatics required to not interpret that verse as a call to sexism are olympics-level.

    I don’t actually have a vested interest in doing the mental gymnastics either way. But I do find it fascinating how deeply knowledgeable and creative some people get in order to pretend that the Bible is actually woke lmao.


  • It has certainly helped to be able to work from home in the last couple years so I do take a walk during lunchtime. Working in an office you’re expected to socialize during lunch breaks, which happen indoors…

    Even then, 30 minutes of daylight every day five days a week in the best case scenario is NOT a lot, especially when it’s cloudy for weeks on end so saying “daylight” is already kind of stretching it.
