FFUUUuucccckkk me sideways. So I decided to look into USB type-c's power delivery and alt modes. Cause I kinda want to make an adapter card to run my displays over a single cable. TLDR of the rest: USB-C has some huge capabilities which noone is interested in using since its way to complex to handle for what its worth in the end.
Now PD alone is kinda ok to deal with since a lot of powerbanks use it and some hobby guys documented how to work with it. I find it really odd thou that you NEED to use a dedicated IC for using the configuration chanel to negotiate how much power you can draw. Why the USB standard didnt use some simple 5V low speed signalling? Also the standard says that you only have to implement 5v 0.6A with every other power level being optional. (This is also true for cables. Most manufacturers use only the USB 2.0 standard for them and brag about how fast type-C is. ლ(ಠ益ಠლ) )
Now to the alt modes. These motherfuckers are a real shitshow to deal with. First you need a Mux to deal with USB-C's two way insertion, so your signals wont get flipped. Next thing is that you have four lanes at your disposal in alt mode. Which you can either use for four Display Port Lanes or two DP lanes and two USB 3.0 lanes. (You always get USB 2.0) Now you may think that there would be one simple chip to do it all? Nope you need atleast two at the price of 6$ each. One for PD and one for Alt modes. Both are very hard to solder (QFN, 0.5 mm pitch 40+ pins) TI ended up being the only one with a decent offering of IC's that do what I need. As for working with them, you would think that you just slap a simple MCU on there that communicates over I2C or SPI to configure the chips? Nope! You program the chips memory from which it configures itsself. And the programming is done with some TI tool which gives me no idea as to how you can handle everything whith no control logic behind it.
Looking into alternative IC's leaves me with cypress semi. And their documentation is basically a total mess. I wanna know what that chip is good for and what I need to do to make it work. I dont care about technical details mixed with marketing jargon nobody understands. And I really despise that I have to register just to download a datasheet. Especially since there is no info about it on the main page.
And this whole rant hasnt even touched the topic that USB-C only uses DP and nothing else. So you better hope that you have DP++ so you can use a passive conversion.
This was my Ted Talk about USB-C. Some info in it may be subject to my stupidity and errors as it currently is 02:15 in the morning and I need some sleep.14 -
TLDR: Read the post.
Bare with me here, I am new to all of this jazz. But I wanted to tell a story.
I have been a programmer for a while now, working on various projects with various companies, doing various things. I know that sounds vague, but it's the truth.
I never work on the same thing, ever, I never work with any fancy IDE, because I don't need one. I personally believe no developer works with the massive huge code base all at once, but instead works on it in pieces. That's a story for another day.
I have seen the shittiest of the shittiest and some how survived, I have been beaten down by code bases that were out sourced yet some how managed to stand up and gain my baring and fight back. I have dealt with clients, bosses and idiots from A-Z. Watching them all scramble around for their pennies like greedy rich white men seeking more pennies to swim in.
Some how I survived all this. I started working from home almost 3 years ago, the freedom is exhilarating. The ability to fuck off for most of the day and work at night, or work all morning and fuck off. There's nothing better.
As you work from home you think, this will be amazing. Until the crippling loneliness takes over and even the 6th bottle of beer doesn't quench the thirst of human contact. The pain of being trapped in the four white walls of your office makes that bottle of tequila, to numb out the emptiness inside look more satisfying.
At some point, you crawl out of your space to find people to interact with, refusing to be beaten down by both shit code and loneliness only to find all your friends, family and significant others are working, in offices, where they cant just fuck off for a day with you. The silence of the house, the office, the what ever becomes deafening.
its crawling all over you like bugs that pick away at your mind, breaking you, hating you. So you decide that a coffee shop is the best place, only to sit there and people watch or check Facebook or what ever else people do at coffee shops that isn't actually work.
The point in all of this, is that working from home is both a positive and a negative. It has destroyed me, created a workaholic and, probably, an alcoholic. There isnt a day I dont wish that I could sleep away the deafening silence of the world around me as every one busies off to the office.
One might think: get an office job, but I have become accustomed to my misery, pain and suffering of working from home, isolated and medicated by vaping and alcohol. the freedom, from what I have found, is worth more then the sacrifice of it - to work around people I slowly begin to hate, people that make me want to overdose on anything rather then see their smug faces and be beaten down by their idiotic words, code bases and money grubbing hands...
I guess I'll get back to work now, in my house, with my cats, my vape and my beer. Here's to freedom and the sacrifices that go along with it.5 -
Should I be excited or concerned?
Newbie dev(babydev) who just learned string vs int and the word "boolean", is SUPER into data parsing, extrapolation and recursion... without knowing what any of those terms.
2 ½ hrs later. still nothing... assuming he was confused, I set up a 'quick' call...near 3 hrs later I think he got that it was only meant so I could see if/where he didnt understand... not dive into building extensive data arch... hopefully.
So, we need some basic af PHP forms for some public-provided input into a mySQL db. I figured I'd have him look up mySQL variables/fields, teach him a bit about proper db/field setup and give him something to practice on his currently untouched linux container I just set up so he could have a static ipv4 and cli on our new block (yea... he's spoiled, but has no clue).
I asked him to list some traits of X that he thinks could be relevant. Then to essentially briefly explain the logic to deciding/returning the values/how to store in the db... essentially basic conditionals and for loops... which is also quite new to him.
I love databases; I know I'm not in the majority... I assumed he'd get a couple traits in his mind and exhaust himself breaking them down. I was wrong. He was/likely is in his sleep now, over complicating something that was just meant as a basic af.
Fyi, the company is currently weighted towards more autistics (him and myself included) than neurotypicals.
I know I was(still am) extremely abnormal, especially when it comes to things like data.
So, should I be concerned/have him focus elsewhere for a bit?... I dont want to have him burnout before he even gets to installing mySQL44
