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 ^^29 -
Boss: Give me unrestricted access in the system.
Me: It's dangerous. You might break something.
Boss: I'll be careful.
Me: *gives access*
This happened 2 years ago. Now every week he deletes something he shouldn't and break a module for him or for the clients using our system.
Just woke up in a rant email saying that "oUr OnLiNe StOrE DoEs NoT wOrK". Well, that's because you have delete the Cart configuration for all the clients you dumbass. What the fuck were you thinking when you deleted that?16 -
Actual rant time. And oh boy, is it pissy.
If you've read my posts, you've caught glimpses of this struggle. And it's come to quite a head.
First off, let it be known that WINDOWS Boot Manager ate GRUB, not the other way around. Windows was the instigator here. And when I reinstalled GRUB, Windows threw a tantrum and won't boot anymore. I went through every obvious fix, everything tech support would ever think of, before I called them. I just got this laptop this week, so it must be in warranty, right? Wrong. The reseller only accepts it unopened, and the manufacturer only covers hardware issues. I found this after screaming past a pretty idiotic 'customer representative' ("Thank you for answering basic questions. Thank you for your patience. Thank you for repeating obvious information I didn't catch the first three times you said it. Thank you for letting me follow my script." For real. Are you tech support, or emotional support? You sound like a middle school counselor.) to an xkcd-shibboleth type 'advanced support'. All of this only to be told, "No, you can't fix it yourself, because we won't give you the license key YOU already bought with the computer." And we already know there's no way Microsoft is going to swoop in and save the day. It's their product that's so faulty in the first place. (Debian is perfectly fine.)
So I found a hidden partition with a single file called 'Image' and I'm currently researching how to reverse-engineer WIM and SWM files to basically replicate Dell's manufacturing process because they won't take it back even to do a simple factory reset and send it right back.
What the fuck, Dell.
As for you, Microsoft, you're going to make it so difficult to use your shit product that I have to choose between an arduous, dangerous, and likely illegal process to reclaim what I ALREADY BOUGHT, or just _not use_ a license key? (Which, there's no penalty for that.) Why am I going so far out of my way to legitimize myself to you, when you're probably selling backdoors and private data of mine anyway? Why do I owe you anything?
Oh, right. Because I couldn't get Fallout 3 to run in Wine. Because the game industry follows money, not common sense. Because you marketed upon idiocy and cheapness and won a global share.
Fuck you. Fuck everything. Gah.
VS Code is pretty good, though.20 -
This has been said countless times before me, and way better than me that’s supper tired, but I need to rant out
And what I’m ranting out today, is Apple. Its essence, its core, the reason it still exists: the ECOSYSTEM!
The problem with Apple ecosystem is that it’s the ecosystem of a fucking PRISON!
People like it because it works well together , but it’s sure that in a prison, the path from your cell to the cantine is pretty optimized; you get forced there! And you might try to get your food elsewhere, but the walls of the prison are made to be difficult to cross. Especially on mobile, where they’re making it harder and harder to escape, to make a jailbreak (pun-intended). Keeping you the loyal little sheep, or the forcing you to it.
That prison is also made private, a little club, to attract people to it. They even got their own little system to talk to each other, but oh god protect them from their little messages to pass the walls of the prison.
And all that prison is guarded by the warden, watching from high in the cloud. Forcing you to report yourself to him to be part of that prison.
That prison, also, can only be entered with specific vehicles, provided by the prison, to ensure maximum compatibility and efficiency. Good luck entering with a disguised vehicle if you find the official ones too pricey for their parts.
They also provided pressure tubes to send things from one cell to another. While being only simple pressure tubes like any other, they’re acclaimed because they’re apparently easier to use than the other 3rd party pressure tubes that can send things to the outside. Why? Because, oh yes it’s already in everybody’s cells (of that prison, outside is dangerous) and the other tubes have been conveniently being placed somewhere harder to reach.
Another thing they have are those windows that can view the outside. While being maybe less clear than some other windows, they are ok. But if you ever consider going mobile to enjoy that safari with lions, then man do they love bringing you back to that window.
Ok so I’m done with the prison metaphor, or I won’t sleep.
The ecosystem is probably the major reason Apple is still there. You buy from there because you’re a prisoner (I guess I’m not finished with the metaphor after all).
This is a prime example of RMS’s quote “If the user doesn’t control the software, the software controls the user”
AirDrop isn’t some sort of revolutionary tech, it uses a well established protocol that other implementations use to do the same thing. They could really easily open source the protocol and allow everyone to profit, but they won’t, because that would mean you don’t have to buy Apple.
That’s why I militate for open source, decentralized and standardized protocols. Because that way, we control the software, and it doesn’t control us.
All the things I said aren’t so bad because when you buy Apple, you make a choice. But I don’t have a choice, I am typing this on an Apple device, because I need to (I won’t elaborate on that) because of that fucking *ecosystem*
I am really tired, so half the sentences probably don’t make sense, but thanks for coming to my stupid TED talk.12 -
REAL Programmers Don't //COMMENT their </CODE>.

I know I added a rant to wk65 already, but this is another one.
At my final project at school, I made an app that registered all your medicine, surgeries, appointments and medicine alarms, so it worked as a medical history. It also was able to show on the lock screen, in case of emergency, your allergies and recent but dangerous surgeries.
At the presentation day there were 3 guys, me and two of my colleagues. The first one had a car dealership tracker, really awesome app, which I helped build by teaching him everything I knew about Android, I didn't do any code, I really just taught him. The second guy, he made a pharmacy tracker, to which, again, I helped make without doing MOST code (I helped on obtaining GPS data). First presentation was awesome, second presentation was really boring because the guy was constantly showing the judges that the app could detect when you were offline (really simple to do).
At my presentation, I thought it was horrible, super nervous and I even thought I was trembling.
So, then, the judges spoke, apparently they knew I helped the previous two, they thought I had the best app, they thought I had the best presentation and needless to say, I got 20/20 on the project. One of the judges even said that if I was selling the app, he'd buy it.
The second colleague didn't like that, and I later found out he was focusing so much on that offline stuff because he wanted to show he was better than me, shows that I really need to see who I really should help...
I felt really really badass after that day, because I left the school, and to this day, I had the best app/project and grades that school had seen and given. Even more when the school offered me a scholarship!3 -
Oh man, its been forever since I've had an actual rant.
so my work ethic is to the point where it's all last minute. My eduction is all last minute. Personal problem, and don't know how to fix that. but it's just getting out of hand.
tbh, I'm at the point of considering dropping uni like this is no joke. maybe transfer to a cheaper because the financials are no good either.
I also need a new job because the place I'm at is no good. here a few things about it:
1) Its Industrial, not really tech related
2) the dudes expect ME to GO TO THEM and ask for help. Not how I roll
3) not the best atmosphere -- I don't really like the 4 total employees, including myself
4) nearly minimum wage
the pros?
1) I learn about my car
2) I can use the shop to fix my car
3) Free stuff (for example, a projector and lunch everyday
4) We're getting a server (soon?)
5) I buy computers for them, they pay me
But seriously, my grades in school are slipping (nowhere dangerous yet) and I am too stressed. At least I'll be getting in more dev work
Moreover, I want to get in some actual learning with Swift, but I can never manage to make time. Plus, games are a thing that I do, also family and friends, also religion is a thing, also work and school, also sleep. No time? Me neither.
Like the organization of this rant? Me too.4 -
Oh no AI can destroy hummanity in the future! It is like skynet and such... Bad! It will be the end! FEAR THE AI!
Yeah so i cant sleep now so im writting a rant about that.
What a load of bullshit.
AI is just a bunch of if elses, and im not joking, they might not be binary and some architectures of ML are more complex but in general they are a lot of little neurons that decide that to output depending on the input. Even humans work that way. It is complicated to analyse it yes. But it is not going to end humanity. Why? Because by itself it is useless. Just like human without arms and legs.
But but but... internet.... nukes... robots! Yeah... So maybe DONT FUCKING GIVE IT BLOODY WEAPONS?! Would you wire a fucking random number generator to a bomb? If you cant predict actions of a black box dont give it fucking influence over anything! This is why goverment isnt giving away nukes to everybody!
Also if you think that your skynet will take control of the internet remember how flawless our infrastructure is and how that infrastructure is so fast that it will be able to accomodate terabytes per second or more throughput needed by the AI to operate. If you connect it to the internet using USB 2.0 it wont be able to do anything bloody dangerous because it cant overcome laws of physics... If the connection isnt the issue just imagine the AI struggle to hack every possible server without knowing about those 1 000 000 errors and "features" that those servers were equiped with by their master programmers... We cant make them work propely yet alone modify them to do something sinister!
AI is a tool just like a nuclear power. You can use it safely but if you are a idiot then... No matter what is the technology you are going to fuck shit up.
Making a reactor that can go prompt critical? Giving AI weapons or controls over something important? Making nukes without proper antitamper measures? Building a chemical plant without the means to contain potential chemical leak? Just doing something stupid? Yeah that is the cause of the damage, not the technology itself.
And that is true for everything in life not only AI.5 -
I'll post a rant (will be long) soon-ish on the root of the asinine problem...
TL;DR
Anyone got a better suggestion of killing a WLAN router signal than a Faraday Cage?
-----------------------
As to the point as I can manage atm...
My ISP forces a proprietary router/modem for them to script my static IPv4 block (/28, aka 13 usable). Modifying this equipment in any way or using the vast majority of tactics to modify its behaviour = Federal Felony... with my history, it couldn't be construed as mistake/ignorance of this fact, so I'd likely end up working for some branch of the gov to mitigate the costs of standard prison (on both ends... handicapped af = expensive af to comply with base human rights laws... plus I'd be a dangerous prisoner from what I've been told).
I NEED the ipv6 functionality TOTALLY off... I've written this into every kernel and every container config at kernel level.
The issue is, I don't trust their shit device (which "should" also be set to no ipv6 via gui... non-GUI = fed felony).
This horrid device, they apparently made them for home use initially (to be fair it has decent specs and tolerable RAM), so included WiFi... that comes on by itself.
Disable the WiFi!... except I cant (at least not without 'tampering').
Why? Well acc to the GUI it's not enabled in the first place. Acc to the 'tech support' it's apparently a paid feature (yes, nonsense) that I have not paid for (nor would I), meaning on their end's GUI and DBs I also don't have WiFi ability from that dev.
So... Not trusting the other settings and the dev, being something im not allowed to directly config outside of their GUI that doesn't realise it's putting out a usable signal despite registering DHCP on behalf of that non-existent signal. I NEED to kill those signals.
I realise it likely sounds extreme to make and use a Faraday Cage for a router/modem (secondary modem, it parses the initial modem's output, via script, to allow the static block to be accessed). I really dont know any other way that's legal to restrict it.
Oh, in case unclear, I have tried so many ways to get them to just allow me to use any device (pref. mine, but even their's) that i can simply script myself... it's a no-go.20 -
I feel like ubuntu gets too much attention. While it is good (even though I used it for all of about 3 weeks) it gets way too much attention and I don't know why. I can also say the same about mint. These two distros are probably the most well known and I find they actually lack a bunch of things that I love in my distro. Ubuntu has effectively branded gnome and is basically always bragging like "hey look our animations are at a high fps now" when kde plasma has been doing that for ages. Gnome and cinnamon (i find ) lack a lot of customization options and generally aren't really fun to work with. I eventually settled with arch using kde because I wanted an os that was going to be hard but would be forgiving in it's challenges and customiZations and I got that. Ubuntu and mint can be good for first timers but I feel like they get more attention then they should and others don't get as much.
Sorry for the terrible rant with probably a lot of typos. It's late and I have an opinion, it is always dangerous when I have an opinion. I don't mean to offend these distros or their users. What I say is my opinion and what I believe but hey I might be wrong.

!rant, but self flaggelation.
Been 3 weeks with my new company.
They are M$ shop, so got the Surface Book and top specced base.
And today I spilled coffee on it 😱
Granted, I had this coming. Over the years I've had many laptops, and put them in all sorts of dangerous situations. But of course it happens now to embarrass me at the new company.
Does anyone have any experience with surface service or returning, and cost? 💸4 -

Once I was in a programming class, and the teacher was explaining the subject for the class, and this guy asks something (about using an else after an if condition, because of efficiency, I think) and he replies with something like "yeah, you know, I like to live dangerous". I kid you not (yes, he said DANGEROUS instead of DANGEROUSLY). I had to try not to laugh out loud.
