Long rant ahead. Should take about 2-3 minutes to read. So feel free to refill your cup of coffee and take a seat :)

It turns out that the battery in my new Nexus 6P is almost dead. Well not that I didn't expect that, the seller even explicitly put that in the product page. But it got me thinking.. why? Lithium batteries are often good for some 10k charges, meaning that they could last almost 30 years when charged every day! They'd outlive an entire generation of people!

Then I took a look at the USB-C wall charger that Huawei delivered with this thing. A 5V 3A brick. When I saw that, I immediately realized.. aah, that's why this battery crapped out after a mere 2 years.

See, while batteries are often advertised as capable of several amps (like 7A with my LiitoKala 18650 batteries that I often use in projects), that's only the current that they can safely take or deliver without blowing up. The manufacturer doesn't make this current rating with longevity in mind. It's the absolute maximum in current that a given battery can safely handle.

The longevity on the other hand directly depends on the demand that's placed on the battery. 500mA which is standard USB 2.0 rating or 1A which is standard USB 3.0 rating, no sweat. The battery will live for at least a decade of daily charges and discharges like that no problem.

But when you start shoving 3A continuous into a battery, that's when it will suffer. Imagine that your current workload is 500mA and suddenly you get shoved 6 times that work upon you. How long would you last?

Oh and not only the current is a problem, I suspect that it also overvolts the battery to maintain a constant current all the way till the end. When I charged my lithium cells with my lab bench power supply, the battery would only take a few milliamps when it got close to the supply voltage. Quick bit of knowledge: lithium cells are charged at constant current first, then when the current drops below that, it continues at constant voltage - usually 4.2 or 4.35V depending on the battery. So you'd set your lab bench power supply at 4.2V 500mA. But in that constant voltage mode, as the battery's voltage and the supply's voltage equalize, the current drops because the voltage difference becomes lower. Remember, voltage is what causes current to flow. Overvolting at the supply to stay in constant current mode all the way till the end speeds this process up but can be dangerous and requires constant monitoring of the battery voltage.

So, why does Huawei and a bunch of other manufacturers make these 3A power chargers? Well first it's because consumer demands ever more, regardless of the fact that they can just charge at 500mA for the night (8h of sleep) and charge a 4000mAh battery from 0 to 100% no problem. Secondly it's because sometimes you need that little bit of extra juice fast, like when you forgot to plug the damn thing in and you've got only 30 minutes in the morning to pour some charge into it.

But people use those damn fucking things even when they go to bed, making that 3A torture a fucking standard process!! And then they complain that their batteries go to shit?!

Hopefully this now made you realize that the fast charger shouldn't be used as a regular charger ^^

You know what? I'm gonna rant about it because it's 2AM, I can't sleep from anger, and the pain from the workout wasn't enough to keep my head straight. I don't care if you read this. I just need to let it out.

You're a fucking dick. You have the biggest ego I've ever seen and what you did today had me holding back tears from rage and trying hard not to punch you in the neck. I don't see why that sort of shit is necessary when working with somebody.

Your team "borrowed" me. That wasn't my project, the client requested me to be there. Your first reaction when you thought the task was just a small change is "I don't think you can do it." It turns out, it was bigger than that, so why don't you volunteer doing it now? It turns out, you only worked on small tasks.

It's your project, you've been there for years. I was instructed to ask you how to set it up because you're supposed to know where things are. It's not like I'm asking you anything that can be resolved through logic or Google. All my questions are project-specific - which repository, how are you testing this, how can I set this up for this version you're using and the clusterfuck of microservices dumped into one place with 12 YAML files, etc. If you had a README file, I'll gladly read it. To be fair, you do but it's fucking empty.

I tried to set it up directly in cloud shell (Linux). I get errors about packages that aren't there, I resolve them one by one. Then finally, I'm stuck on the SDK. Your project uses an old version (when the new one has been around for 10 years) and you're setting a bunch of parameters from different configuration files that isn't part of the standard deploy so I ask you about it and your response is:

"What shell? The one on the internet? SDK? You don't need an SDK! I hate to bust your ego but you don't need an SDK. I don't know why you're doing that. If you just ran it on your local machine, it would work without additional setup."

Wow. Amazing response to a question. As if I did some hacky stuff and your assumption is I'm making things more complicated. It's almost like you didn't overreact. So I stayed calm and said, "Okay, I'll install your IDE on Windows and run it there." A few minutes later, same SDK error. Oh, I thought this is supposed to work locally without doing anything? It turns out, you made a lot of hacky dacky setup on your workstation and you forgot about it but hey, I have the huge ego. What do I know? My head is so heavy, I can barely see.

Realizing how wrong you were with your previous reaction, you attempted to initiate smalltalk. "So you use Linux in your previous project? Amazing." Fuck you, man. Fuck you and your dog smile. I'll keep it professional but I'll be asking the developers in the client side moving forward. You wasted so much time of my life and irritated the veins in my temples.

Finally, you say "Install the SDK" and in an attempt to shake your memory, I say "So you need an SDK" but of course, you have to look smart and say "Of course you need it, that's the SDK!"

When it started working, it turns out, you can only run the unit tests and you suggested I develop all of these with just unit tests. 30 minutes before the shift ends, you admit that you never got it to work. Wow, what a waste of time. Ego, huh?

Let's recap:
Your boss, the client, your fellow developers interviewed me and I passed all of them (technical exams, live coding, theoretical bullshit, etc.) including the exam YOU created. My first week in the office, you didn't talk to me even when the manager asked you to. The first time you talked to me, all you did was brag about how you taught everyone in the project, how you're the only senior there, talked trash about the managers, said everyone else is too lazy to learn by themselves, and threw it to my face that I wouldn't have gotten the job if you interviewed me. I've been there for like what? One week? I don't even have access to any of your shit. I wasn't even in the same project as you are.

I gave you the benefit of the doubt, maybe that's just how you talk, maybe I can learn something from you. I get it, man. The people around you are "lazy" and "stupid" and you taught all of them. Your ego must have inflated from all those people completely dependent on you so you assumed that everyone else is the same.

I've taught people myself but I've never treated anyone like that. I don't walk around the halls like they owe me their lives. I don't blow up on them and then humiliate myself because it turns out I'm terribly wrong.

I don't know what to make of this. It's either you're underestimating me or you've seen my previous projects and assumed I have a huge ego that needs to be broken down. I asked nicely but wow, what the fuck kind of reaction is that? I guess you busted your own ego.

Damn, fuck you. Three months of this shit and I lost my patience.

Broken app is broken again. This app is broken so often and so hard, I'm struggling to give a damn.

These fuckers need to take their shitty project, code and managers especially, and launch them into Mars

They blame us and everyone else for their shit and I'm done with it. I need to sleep and not have these fools call me at all fucking hours.

This god damned fucking group Project in University!
How did 2 of these stupid as shit ballsacks of useless crap even manage to get through the first 4 semesters?
And now they can't contribute to anything. Or even worse is when they do contribut and mess up everything. Its like trying to play chess with a god damn bird.
Now this fucking project is robbing me of my sleep and the fucking idiots that organize the whole damn thing don't even care about that it's basically just me and one other guy carrying the fucking project.
Stupid theoretic computer science people that get to use as as slaves for their resarch because we "need to get some experience".
If I get anymore fucking experience of how a big software production works I'm going to fucking murder someone...
Verdammtes Arschgeigengesöcks.
Diese schwanzlutschenden Pferdgefickten Eiterwichsende Hurrensöhne.

I fucking shit Blood because I'm in too much stress. And I mean that literally. My fucking asshole burst open because I fucking have to deal with you dirty disgusting scumbags.

So I just finished a prototyp for my thesis. Still need to segment the real data myself and collect some statistics stuff to write about the network, but I am pretty proud of the result considering the dataset is very small.

For now I need some god damn sleep.

I'm so tired.
Got enough sleep but tired nevertheless every day.

Situation in the company isn't helping, would really like to get a review as I'm really close to a 'final' version for productive use, none given.
Didn't think far enough and didn't include various OO-things when starting to program this application, so I had to rewrite lots of it. It certainly got better by the time but as it's a grown structure I'd feel happier if someone other than me had seen and cursed the code.
Coworker that has most experience in C# only once implemented something with multiple threads, couldn't help me there.
Could not test the code yet because the hardware was inaccessible and is now potentially broken.
I really like working independently, nevertheless I feel a little bit lost at sea - I can deal with that, but it's exhausting.
Also, trying to get an answer from the colleague who should act as my supervisor whether or not I can work remotely during a CS related course in the semester break for > 2 weeks now. Course admission is the mid of January so I'd like to have an answer this year so I can repeat the basics I'll need if necessary.
Also, Midterm is coming.

It's a lot of little things piling up right now I wouldn't mind if there were only 1-2 of them.
I'm just so damn tired.
I'll go to sleep now.

(In happy news: my internet connection is working pretty decent now, technician that fucked it up apologized and said that he probably needs glasses, he misread the connection number. :D)

Ohhhh damn sleep fuck you.
I haven't slept for 2 days and now it hit me.
But I need to finish that bug fix now.
Maaaaaaaaaan that's hard.
After this I will sleep really loooooooong.

Literally slept off during this zoom call. I just woke up I don't wth everyone is talking about. Turns out my PR was up for discussion. Now I have to review a bunch of shit I thought I was done with. OS maintainers can be a pain sometimes 😭

Can some drone operator please end my suffering existence?
I just got on a bus from Berlin to Munich (8h trip) and apperantly some fuckwits thought it was a great idea to destroy the GOD DAMN FREE WIFI. ONLY DRUNK ASSHATS COULD BE SO STUPID. I need a podcast to sleep well but since I already used up my mobile data volume, I'm stuck in here, surrounded by idiots and lost to the world.

I am making new mistakes and acing the consequences everyday. So here's another tip: FUCKING SLEEP CORRECTLY YOU PEEPS. ESPECIALLY COLLEGE AND STUDENTS . college is such an easy phase of life that gives us so many bad habits. mine is to sleep 2/3 hours, and face the next day . at college that used to cost me nothing since we didn't had to use our brains much there.

But damn... today i slept for <3 hours and my day has been almost shit... could not solve a very simple bug and was continuously going towards the negative answers( no it isn't possible, it can't be done, I don't understand this) and asking for help. I hope they are gonna forgive me once , but I wasted my fresher card due to lack of sleep .
You need your active, innovative brain. don't ruin it

So yeah I do work on windows laptop, with multiple remote sessions into windows servers. (deal with it)

I don't like restarting (who does?) so mostly put laptop to sleep. Sometime it bugs out after several cycles and clipboard stops working.

And I sometimes need copying / pasting texts into similar files on multiple servers.

Damn it, because of this bug I developed a mild paranoia in a sense that once i have text in clipboard I do ctrl+a, del in the target file and then paste, just to see visually that I did in fact successfully pasted that shit.

My computer has gone to repair so for the meantime I'm computer-less. Which sucks big time because I have projects and tests coming up (not to mention personal projects and other stuff I've been asked to do) and I kinda have to leech off my friends and I don't like doing that, but, for now, it's what I'm doing. My old toshiba couldn't handle whatever I have to do, damn thing should be going through menopause or something. I wasn't a good owner LoL
I never really know if it'll boot during the first minute after I turn it on or if'll take it hours to do so, so I don't wanna risk it taking it with me to uni 😬 Not to mention it's still running Vista 😅
So my brother left to go to a friend's house until sunday so for the today and tomorrow I have access to the beast that is his computer ☺
I don't mean beast as a bad thing, it's a good computer, but it has an almost full SSD and I need to install a couple things so I can work on it :') (I'll uninstall them later and try to leave it as I found it LoL)
I can finally take a bit to play as well 😥 as I haven't been able to do so, as not only my PC is on repair, but I've been leaving uni late (after midnight - I valour my sleep OK). Luckily one of my house mates lets me use her PC after she goes to bed or her bf arrives to our house. The other day I managed to install steam and play a bit (she gave me permission to do so and I uninstalled them later) 😂 her computer almost died on me, it only has 4GB of RAM :') poor thing was over working to keep up LoL
Now, my brother's computer has a mechanical keyboard and besides the macro keys (they're on the far end of the keyboard, where you'd expect the shift/ctrl/caps lock/etc keys to be), I'm loving it tbh. It's a cheap keyboard, my mom didn't want to buy anything too fancy for him, but I like the sounds it makes 😅 may get one for myself (a mechanical keyboard I mean LoL. I really liked one I saw here on devRant that looked like a typewriter but it's WAY out of my league for now HaHa)
