@i2cjak *Puaj...a PIC...urgh. *Look! A bunch of gates with a clock! *What's that....P...I...C...? And what would it be? A midterm high school tech project? * Back in 2010 I designed by hand a core using Tanner L-edit and MOSIS' AMIS05 process... It was neat and better than PIC...

@Cypher1984 Mismo orden que la pizza: sustrato, salsa, queso. Cualquier otro orden es una blasfemia, una imprecación que clama la venganza inmediata del todopoderoso, olas como montañas, ríos de lava y azufre, el león conviviendo con el cordero y el final de los días.

@ThePhysicsMemes You know, I have that question too. Why not use it where a lot of heat is needed? With all security measures, of course...

A prisoner in Iowa made headlines with a highly unusual legal argument: that his life sentence had technically ended after he briefly died in the hospital and was resuscitated. Benjamin Schreiber, who was serving a life sentence without parole for murder, suffered severe septic shock in 2015. His heart stopped, and doctors had to revive him five times. After recovering, Schreiber filed an appeal claiming he had “served his life” because he had legally died, even if only temporarily. He argued that being brought back to life meant he was now living a new existence beyond his original sentence. The Iowa Court of Appeals rejected the claim, calling it “unpersuasive and without merit.” The judges ruled that a life sentence means imprisonment for the rest of one’s natural life, not until a temporary medical death. Schreiber remains in prison.

I find this hilarious when the vast majority of rockets use existing technology, because that’s how this whole “engineering” thing works. It’s no secret that Falcon 9 is a simple rocket, technologically speaking, it uses kerosene, has gas-generator engines, it’s really not too special during ascent. The fact that it lands the booster with pinpoint accuracy is what’s so special, and people will deflect and deflect to ignore this fact.

Akinator adivinaba cualquier personaje que pensaras en 20 preguntas. Lanzado en 2007. Sin GPU. Sin transformer. Sin datos curados. Yo lo usé a los 12 años y pensé que era magia. Después estudié machine learning y entendí lo que era realmente. No era una IA. Era un árbol de decisión bayesiano alimentado por las respuestas de los mismos usuarios. Estadística de los 90 corriendo en un servidor barato. 100 millones de personajes en la base. 20 preguntas promedio. Con gente mintiendo, trolleando y poniendo a su perro. Hoy gastamos $100M en modelos que alucinan capitales de países. Akinator no alucinaba. Preguntaba hasta saber. Y ni siquiera era inteligente.

💾😂 It’s actually wild that Gen Z has never experienced the pure serotonin of watching MS-DOS DEFRAG do its little block dance. Your 4GB 386 is choking on life? Just run DEFRAG and stare at it like it’s 1993 Netflix. Don’t fight the hypnosis… become one with the pixels.😵‍💫

THIS GUY BUILT AN ENTIRE WIKIPEDIA THAT IS 100% AI HALLUCINATIONS AND IT'S OPEN SOURCE ON GITHUB it's called Halupedia. nothing on the site existed before you clicked. every article was generated the second you arrived. the site has one rule: the universe only exists when you visit it. it looks exactly like wikipedia. same fonts. same layout. same scholarly citations. same "stumble" button for random articles. the only difference is none of it is real. here are some actual articles currently in the encyclopedia: > the great pigeon census of 1887 > the ministry of slightly wrong maps > chaldic arithmetic — a branch of mathematics where subtraction is forbidden > armund the river mapper — a cartographer who mapped 14,000 leagues of river without leaving his chair > the society for the prevention of unnecessary tuesdays every article page also tells you how many people are reading it right now. it says: "you alone are consulting this folio at present." the creator's own tagline for the site is the most unhinged sentence i've read this year: "an encyclopedia of a universe that does not exist until you visit it" the entire backend is a single open source repo called vibeserver. one guy. one description on github: "a little webserver making things up just in time." we built the largest knowledge base in human history and the very first thing a guy did with it was make a hallucinated mirror universe and put it on the open web. the internet is healing.

@matthewvenn My first chip ever also had 2 stupid mistakes. Outputs were laid.(M1 and M2) but I didn't place a via. We speculated about experimenting with an ion beam microscope but...never got to it...:'(

@aakashgupta That's idiotic. With Apple design, it can have a little almost invisible door pushed by the USB plug, it can have wireless pad for charging, it can have a small slave human living inside that opens an usb gate. Apple users pay. It's just bad decisions and bad design.

Let me explain exactly why Apple ships the Magic Mouse charging port on the bottom, because no one seems to get it. This is not an oversight. Apple has shipped this exact design since 2015. They updated the mouse in October 2024 to USB-C and kept the port on the bottom anyway. They actively block the mouse from working when it receives power, which kills every third-party case that tries to move the port to the side. Apple watcher John Gruber has said Apple designers tried front-port versions and rejected all of them because every one looked worse. Ten years of memes. A decade of competitor mockery. An entire cottage industry of accessory makers trying to fix this. Apple held the line on every single attempt. The reason is the entire Apple thesis. Every other hardware company asks "is it usable?" Apple asks "is anything visible that I wouldn't put on a museum shelf?" When usability and visibility collide, they hide the usability. iMac power button on the back since 1998. Headphone jack deleted in 2016. Every port stripped from the MacBook Pro for five years before they admitted defeat. Touch Bar replaced function keys for a cleaner look and died after five years. The Magic Mouse is the purest version of the discipline. The cost is a few minutes of charging downtime every couple of months. The benefit is the mouse looks beautiful 100% of the time it is in your hand. Apple ran that trade in 2015 and has refused every chance to renegotiate it. Run the math on what this aesthetic discipline buys them. Apple sells a $99 mouse that has to be flipped on its back to charge. Logitech sells better mice for $40 with the port in the right place. Apple is worth $4.3 trillion. Logitech is worth $15 billion. A 280x gap on the same category of product. The trade was never even close.

@Gaurab I wouldn't be surprised if @elonmusk pulls it. He may even start a factory in orbit. No gravity, no oxygen, really a nice place to grow a single crystal...

Four foundries on Earth cast the single-crystal blades and vanes that let a gas turbine convert 1,500-degree gas into electricity. PCC and Howmet hold about 80% of the single-crystal market. Doncasters and CPP take most of the rest. Every heavy-frame gas turbine ordered in the past 18 months is sold out through 2030. Elon Musk on @dwarkesh_sp traced his own xAI Colossus power problem one layer down past the turbines and landed on the blades. He said SpaceX and Tesla will likely have to cast their own. We manufacture chemicals. Casting a single-crystal blade is not a metallurgy problem. It is a chemistry problem. The four foundries that cast them spent thirty years driving sulfur down to parts per billion and oxygen down to parts per million. Vacuum, gradient solidification, and mold chemistry are why nobody else can cast them. The bottleneck is chemistry.

@madietlx Usually those numbers are a batchcode, or a datecode, some are 'gain lots'. Eg: BC548A are lower gain, B bigger and C the biggest. But within those are gain 'sub divisions'.
