til that during world war 2 the british military produced five million linseed cakes infected with anthrax spores. the plan called operation vegetarian was designed to be dropped over germany to wipe out their beef supply and would have killed millions of civilians
en.wikipedia.orgreplace all generative ai in search engines with a literal guy named dave sitting in a windowless room who just frantically googles things for you and types back his best guess
he works around the clock if you ask a complex coding question or a recipe you just get to watch a live webcam feed of dave sweating and reading stack overflow trying to figure it out for you
it would be infinitely more reliable and entertaining than whatever silicon valley is trying to force on our phones right now
would anyone else actually pay a premium subscription just to use dave instead of an algorithm
ysk: if your laptop trackpad suddenly becomes very stiff and hard to click do not press harder on it. your battery is swelling and could explode
most modern laptops have the lithium battery sitting directly underneath the trackpad. when these batteries start failing they produce highly flammable gas and puff up like a balloon
people usually just think their mouse is broken and try to push down on it harder. applying pressure to a swollen lithium battery can easily puncture the thin membrane and cause it to violently burst into a chemical fire that is almost impossible to put out with water
if your trackpad stops clicking normally or the bottom of your laptop looks even slightly pregnant turn it off immediately and carefully move it outside or onto a concrete floor
Why YSK: ignoring a swollen lithium battery or forcing your trackpad to click can trigger an uncontrollable thermal runaway fire that will easily burn your house down or cause severe facial burns
the only reward for hard work is just more work. i am officially doing the bare minimum from now on
i busted my ass to finish all my tasks for the week by thursday afternoon thinking i could just take it easy on friday
instead of letting me chill my manager literally assigned me half of my coworkers backlog because "we are a team and need to help each other out"
so i basically got punished for being efficient while the guy who watches youtube half the day gets bailed out
never doing this again. starting monday every single task is going to take exactly the maximum amount of time i am given. completely done going above and beyond
people who stop walking the second they step through a busy doorway or get off an escalator
it is like they completely forget that other human beings exist in the world behind them
you literally have a whole crowd of people moving at the exact same speed and you just freeze in the bottleneck to check a text message
getting rear ended by strangers just because someone lacks basic spatial awareness is so infuriating
ysk: if your garage door torsion spring ever breaks do not ever try to fix or adjust it yourself
those springs are under an insane amount of tension just to lift a massive heavy door
if you slip with a wrench or the spring snaps it holds enough kinetic energy to literally sever your hand or kill you instantly
just pay a professional to do it because it is absolutely not worth the risk
Why YSK: trying to fix a broken garage door torsion spring without professional tools can result in immediate death or losing a limb due to the extreme tension
til that during ww1 the french built a massive fake replica of paris just outside the real city complete with electrical lights and wooden trains to confuse german bomber pilots at night
en.wikipedia.orgYSK: if you randomly smell fish or urine in your house and you don't own pets or cook seafood, check your electrical outlets immediately
Why YSK: melting plastic components and burning wires inside your walls emit a specific chemical that smells exactly like dead fish or ammonia
a lot of people just spray air freshener and ignore it thinking it is a weird smell from outside but it is actually the early warning sign of an electrical fire about to start behind the drywall
if you smell this you need to go around and sniff your outlets and light switches. if one smells strongly of fish turn off the breaker for that room immediately and call an electrician
have you ever actually heard of this before
imagine going to a country famous for strict laws and caning and deciding to publicly film yourself doing this
dae constantly calculate the exact amount of sleep they will get if they manage to fall asleep right this very second
and then you keep checking the time 30 minutes later and have to do the sad math all over again
does anyone actually just go to sleep without doing this
til crooked teeth and shrinking human jaws are actually a recent lifestyle disease caused by modern soft diets and not just genetics
news.stanford.eduYSK if a company mails u stuff u didnt order u can legally keep it for free
Why YSK: companies sometimes run scams where they send u random packages and then bully u into paying for them or paying return shipping
apparently there is a federal ftc law that says if unordered merchandise shows up with your name on it its legally just a free gift
u honestly dont have to reply to their angry emails or send anything back u can kinda just keep it or trash it
has anyone actually gotten weird random packages like this before
