Friend of mine killed his MacBook with some Softdrink.

Just poured it all over his poor a1502.

He let it dry for a few days, it starts to work again.
Except the battery.

Goes on Amazon and buys a new battery.

New battery doesn't work either and so he tells me about it and I as stupid as I am couldn't resist the temptation to finally work on a MacBook like my "hero" Lois Rossmann does.

So turns out the board is good.
Cleaned it up and basically nothing happened to it.

So what's the deal with "los batlerias"?

The first got hit by liquid, the second had a broken connection to a cell.
That could have happened through my friend, installing it without testing it first, or at the seller, so it being a DOA battery.

Now away from the stupidity of my friend and the situation to the actual source for this rant.

Once something happens to a modern Managed battery, the Battery Management System (BMS) disconnects the voltage from the system and goes into an error state, staying there and not powering anything ever again.
For noobs, it's dead. Buy a new one.

But It can be reset, depending you know how to, and which passwords were set at the factory.
Yes, the common Texas instruments BQ20Zxx chips have default passwords, and apple seems to leav them at default.

The Usb to SMBus adaptors arrived a few days ago and I went to prod the BMS.

There is a very nice available for Windows called BE2works, that I used the demo of to go in and figure out stuff. The full version supports password cracking, the demo not.

After some time figuring out how Smart Battery Systems (SBS) "API" works, I got to actually enter the passwords into the battery to try get into manufacturer and full access mode.

Just to realise, they don't unlock the BMS.

So, to conclude, my friend bought a "new" battery that was most likely cut out of a used / dead macbook, which reports 3000mah as fully charged instead of the 6xxx mah that it should have, with 0 cycles and 0hours used.
And non default access.

This screams after those motherfuckers scaming the shit out of people on Amazon, with refurb, reset, and locked fucken batteries.

I could kill those people right now.

Last but not least,
My friend theoretically can't send it back because I opened the battery to fix the broken connection.
Though maybe, it'll get send back anyway, with some suprise in the package.

One of my colleagues at work has cooked up this amazing amazing method.. and guys brace yourself.. This code is on production..

A friend saw me on stack overflow and said 'wow, 4,000 points - you must do this all day.' I explained that I just do it to reinforce my understanding and not really for points(although those are useful for bounties). I showed them an account with 22k and tried to show how one might choose questions for maximum points vs quick solves for noobs etc. I write overly thorough answers to try and pin-point the blind spot as opposed to just fixing other people's code. It's not often rewarded by points. My friend - conspiracist - was convinced that the 20+k accounts were cheating the system.

At my old work we had a stack overflow account just for asking embarrassing questions that you didn't want on the company record. Silly, I know. Occasionally some of the guys would use it to have fake arguments or just cause trouble for fun / vote each other's stuff up.

So - I reached into 1Password and signed into that account and showed him that you could essentially vote up your answers but that it's not likely how people get points. I voted up my last 5 personal answers as an example and made some comment like 'that is right.' And that was that. Closed the computer. The next day my account was suspended and I was reprimanded for sockpuppeting. So, - in case you think you can get away with cheap tricks - you can't, which is nice to know - but after reading the email - my face was red for hours. How embarrassing! Not quite as bad as that time I got caught stealing a G.I. Joe action figure at the mall...

A couple of weeks ago I had an internship. I worked there with a classmate. We had a simple assignment, but since we're noobs when it comes to web applications (and because you don't learn that in school), we even had a hard time preparing.

Finally, I... I mean "we" decided to use React because it's close to the way we learned to solve problems in school. I asked him to implement a page with a date picker/calendar. I even searched for a repo that. 2 Days later he was still not able to implement it, he experimented with the code, but he
1. didn't even read the readme, just copied the tutorial expecting it to work
2. Didn't even look at the logic behind it.
3. Demanded to use this other repo with less functionality

10-30 minutes should have been more than enough. Instead, I wasted time telling him to read and code properly. He refused the second (and probably also the first), because "Why should I care? We'll be here for 3 weeks and then we're done with this"

Guess whom I'll avoid in any possible group project

Don't you just hate when a junior has been assigned a task in the domain you have experience, and instead of asking you for context and approach, the person asks for the EXACT LINE CHANGES INCLUDING THE LINE NUMBERS TO BE MODIFIED? Might as well assign the task to me.

TL;DR: New(-ish) dev looking for advice to improve workflow and new languages. Hopefully worth a read though :)

Newbie developer here, I took a web applications development class this year since I could take that at another campus rather than do general education courses at my home school, and I have learned and earned a CIW Certification for HTML5, CSS3, and JavaScript, though I know the certificates do squat if I can't apply myself to them, and I have learned PHP and MySQL.

I want to learn more, technically-applicable languages.

My setup is barebones (to a Linux diehard's eyes), with a gaming laptop that I do a lot of workstation stuff on, an RPi 3 B that I do some Linux-y stuff on, and a less-powerful Development Laptop (that I call a devtop) that I occasionally do work away from home on.

I'm sure most will cringe and weep at my workflow, as I use Windows 10 on both systems and the standard NOOBS software on the pi, and I use Brackets as my text editor, as well as the XAMPP AMP stack for testing.

My biggest questions are what could I do to improve my workflow, and what languages should I learn/apply myself to for real-world application (such as Node.js for live-updating server-side applications or C# for Windows applications)?

Thank you for taking the time to read this, any feedback is helpful! I'm just a high school student with a lot of enthusiasm for development!
