Use your noodle

It’s fun. You’ll get a strong sense of satisfaction when your efforts yield a properly working gadget. It feels a bit like you’re a detective solving a murder case, and it’s more fun to use your noodle than your wallet.

squirreling away

No book can make you an expert at anything; that takes years of experience and squirreling away countless nuggets of wisdom gleaned from what did and didn’t work for you.

의미를 몰라도 쓸수 있다는게 포인트. 감정을 짐작해서 사용하고, 그후에 의미를 체크해서 감정을 재확인 하는 과정을 갖는게 자연스럽다.

There was this guy at this plant called Transpo Electronics in Florida. They made circuit boards for car manufacturers. Anyway this one particular guy shuffled around the plant all day, never looking up, never tied his left shoe, spoke in soft mumbles. You could ask him any questions about math, programming, etc he would push his large coke bottle glasses up and give you the answer like it was nothing. He literally designed almost every piece of proprietary technology the company had. The company was abusing the hell out of him too. He only got about 50k a year.

I went over to his house to fix his AC unit as he just didn't deal with it or it was small priority to him for half a year. His 80+ year old mom lived with him (who was in bad shape). So I go there, and it was like something out of Harry Potter, books stacked on books literally to the ceiling everywhere. He said he had already read them all. I didn't charge him. I didn't work at Transpo, I worked for my dad's commercial HVAC company. Transpo had huge chillers and such for their machines so I got to know the ground floor guys pretty well.

I watched this video on a 16inch macbook pro when he'd just uploaded and hoped that this wouldn't happen to me. Got scared and saved everthing important on a cheap flashdrive. A month passed and my mac died with the EXACT SAME ISSUE. The motherboard got replaced for around a thousand bucks and I sold the machine right after it. I lost around $2000 in total. For one time I hoped that you were wrong but.. oh well..
Despite all of this my friends and relatives are asking me advice on buying macs. Buying a PC with soldered SSD is a seriously DUMB move and people need to know about this! There are now way better screens and keyboards on many windows devices and many of them are repairable. Please don't think this is a single model issue. This company is not dumb. These pro devices are things that people rely on to do real work to get paid. When things go wrong and machine gets broken, they know that you'll be ready to pay them more! Apple is indeed evil.

I get so many of these turning up. For those reading/watching; before you even power up the machine, check the PPBUS resistance, check the SSD 2V5 resistance.
If SSD is shorted, remove the VREG and check again; if it's still shorted HARD ( < 1R0 ) then you might be lucky and it's a blown/corroded cap. If it's 3~6R it's probably either the NAND dead or the PCB shorted :(

What ever you do, if you find a corroded cap on the NAND or PPBUS rail next to the NAND VREG, REPLACE THE GODDAMNED VREG first before you even consider powering it back up after removing the short - as sometimes that shorted cap is the only thing that's saving the NAND from a VREG that's likely going to spit out something more than 2V5.

You want PPBUS and NAND 2V5 to be > 400 ohms when warm, or 1K+ when cool. If they're not, then you've got a dead NAND, PCB or other issue still.
