proee··on Failing grades soar with AI usage, dwindling math skills in Berkeley CS classes
The traditional sit down in a lecture hall, listen to professor speak, then come in for a pen and paper test, is outdated for this era of technology. What's the point of physically bringing +300 students into a room for a passive listening experience?

The future of education is rapid back and forth between the student and the teacher. You could image a future where a student sits down all day with an AI system that trains the student, and it won't let them pass until it's confident you know the material. This will happen at different rates for different people, but this is expected.

An ideal education would be getting those skills discs uploaded to you in the Matrix, but unfortunately it will take a bit longer to master them as we don't have full brain-system interfaces (yet).

proee··on Ian's Secure Shoelace Knot
My problem with this knot, is going from step 2 to 3, I get a bit of slippage from the orginal starter knot (step 1). For my running shoes, getting the tightness just right is critical, so not sure how to dial this in?
proee··on Ferrari shares fall after launch of first EV as Jony Ive design proves divisive
Definitely some Toyota Prius vibes. They certainly should take some design risks, but not in the direction of an everyday commuter. I can only image the amount of patting on the backs the Ive team gave each other. Good job guys, on to the next project.

proee··on Memory has grown to nearly two-thirds of AI chip component costs
Memory manufactures sit on a war chest of IP. So even if someone has excess fab capacity and wants to get into memory manufacturing, they will have to fight an uphill battle of about a zillion patents.

Most memory companies have backroom deals to exchange tit-for-tat patent violations against each other.

Not sure how a new memory manufacture comes into being without getting sunk from licensing costs?

proee··on The Silver Swan
Swans do occasionally eat small fish.
proee··on We've made the world too complicated
I think the key is to find the right work/life balance to maintain a fulfilling life. For the work portion of your life, you should find problems that interest you and people that you enjoy working with. For your life balance, you should connect with nature in way that resonates with you, be it hiking or growing food, or exploring new places. And of course, in your life balance you should have relationships that can bring witness to your life's journey and help you along the way.
proee··on I hate soldering
Soldering is fun, especially if you designed the circuit and the pcb yourself. It's like putting together your own frankenstein, with a huge amount of anticipation toward when you finally get to give it power. Just be sure to get the polarity right on those electrolytic caps ;-)
proee··on US Government releases first batch of UAP documents and videos
why not release them all at once?
proee··on I want to live like Costco people
I find the quality of Costco food is lacking, especially things like Chips, which are usually quite stale. The overall experience is also off-putting, compared to a place like Whole Foods, that generally get me excited about cooking.
proee··on CARA 2.0 – “I Built a Better Robot Dog”
I'm sure he could contact a supplier that would change the windings for the same price if he went into production mode. So doing this for his prototype doesn't seem unreasonable. He's under a massive time crunch per his school semester to get this project out the door.
proee··on Removable batteries in smartphones will be mandatory in the EU starting in 2027
Smartwatches should also be on the list. My Apple Watch 8 is at 76% maximum capacity. Apparently it costs $99 to have Apple replace the battery, which is probably not worth it.
proee··on Men who stare at walls
When I was a kid, I would often sit on my bed and stare at the wall. My Dad would walk by my room and ask if everything was ok. I would always say "yeah", since I was literally just thinking.

It's a great feeling to just stare at a wall and think.

My first thought is usually, "If I could think about anything right now, what would it be?" And this frees my mind up to think about what I want to think about.

proee··on Sawe becomes first athlete to run a sub-two-hour marathon in a competitive race
When Vibrams were first popular, I took to training with them on my runs. People told me to "take it easy" or you might get injured. I thought what's the worst that can happen? Well let me tell you. About a month into wearing them, I was doing a hard run and the trail had a section of concrete. My foot felt a sudden sharp pain and "snap!" I broke my 3rd metatarsal bone in my foot. Took a month or so to heal, and I decided to stop using the Vibrams.
proee··on All phones sold in the EU to have replaceable batteries from 2027
This could be "fixed" right now by a software update that limits the maximum charge level to 80% of capacity. However, this comes at the cost of how many minutes of runtime your phone can operate.

So manufactures might just responds to this by making your phone heavier with a bigger battery that is being under utilized.

proee··on I built a 3D printing business and ran it for 8 months
How long did it take to get shipped to you, from click -> doorstep?
proee··on Filing the Corners Off MacBooks
The Apple Watch Ultra also has an aggressively sharp screen edge. It's kept me from upgrading from my current watch (Model 8). But maybe I would get use to it?
proee··on EFF is leaving X
Leading out with "The numbers aren't working out" is a bit disingenuous. If they were "working out", would you continue to stay? If the answer is "no", then just remove the numbers talking point in your justification altogether.
proee··on 12k Tons of Dumped Orange Peel Grew into a Landscape Nobody Expected (2017)
One risk here is that a giant pile of biomass could allow nefarious critters to grow disproportionately. For example, in Alaska, they had giant brush piles that ended up fueling beetle infestations across the state.
proee··on Solar and batteries can power the world
EVs are essentially a giant battery on wheels. Seems there is a good opportunity to configure them as bidirectional power banks for your local grid. You could rewire all parking slots to have a plugin that acts as a bidirectional power station. Imaging how much power could be moved around with such a grid! This would require a major investment in power transmission layouts, but a city full of batteries on wheels.

California has registered around 1M Teslas alone. So this is like having a 1Mx80kwh = 80GWh battery at your service. As a reference, the largest solar + storage facility in California is around 3.2 GWh.

proee··on Artemis II Launch Day Updates
There is a LOC (Loss of Crew) number that is typically calculated for these missions. I'm curious what that is? Early Apollo missions were on the order of 4%.
proee··on The Micron Store: A Semiconductor Brand Strategy That Would Break the Internet
This is a brilliant take because Micron has traditionally struggled with their products being seen as a commodity. There is good value in trying to differential MU as some kind of magic memory company that is better than others (despite it following the same specs).

For the sake of bringing this to different cities and regions, maybe you could do the same thing but with a "Memory Mobile (MM)" that travels around the country like the Oscar Meyer wiener truck.

To motivate visitors, you could offer one "Willy-Wonka" ticket each year, that gets a huge cash price or something cool. Tickets are handed out upon visiting the MM, and at the end of the year, ticket number is announced. Hold on to your ticket kids!

proee··on Honda is killing its EVs
Could it be that the EVs they were planning were just out of touch with what the market wants? Their zero vehicles look butt-ugly in my opinion. They look like concept cars that are great for show, but no serious buyer would consider them for a daily driver.
proee··on AirPods Max 2
I bought the AirPods Max 1 but had to return them because they felt like a vice and were too heavy. I ended up going with the Sony wh-1000xm5, which are much lighter. My only complaint on the Sony is the earcups are not deep enough for my big ears.
proee··on Ask HN: Why can't we just make more RAM?
Outside of fabrication, memory chips also require some very fancy high speed testers that need specialized ICs which are most likely back ordered.
proee··on NASA targets Artemis II crewed moon mission for April 1 launch
Imagine riding in a vehicle that has been tested zero times. I would be terrified. Best of luck to the team.
proee··on PCB devboard the size of a USB-C plug
Just be aware of dorking around with exposed hardware connected to your $2K MBP. If you end up shorting out your DIY circuit, or have external power supplies connected to your dev board, it's very possible you can fry your laptop.

Best practice is to have a completely opto-isolated USB connection between your dev system and test hardware. You can buy a USB opto-isolated system for like $100 that will tell you downstream currents and isolate your hardware.

proee··on Math Notepad
Great tool. Reminds me of Instacalc, which has bee around forever.

proee··on TSA leaves passenger needing surgery after illegally forcing her through scanner
I brought a $14k oscilloscope through TSA once. They flagged the unit and proceeded to inspect it, lifting it by the edges of the plastic front cover and trying to remove it while held in mid-air. I kind of freaked out and said "stop" because the oscilloscope was about to take a free-fall. They were not happy that I spoke up, but luckily it averted a crisis.
proee··on China tests first megawatt-class flying wind turbine
This seems like a really cool idea. I wonder if the US is working on something similar and how practical this really is?
