I have this little hobby project going on for a while now, and I thought it's worth sharing. Now at first blush this might seem like just another screenshot with neofetch.. but this thing has quite the story to tell. This laptop is no less than 17 years old.

So, a Compaq nx7010, a business laptop from 2004. It has had plenty of software and hardware mods alike. Let's start with the software.

It's running run-off-the-mill Debian 9, with a custom kernel. The reason why it's running that version of Debian is because of bugs in the network driver (ipw2200) in Debian 10, causing it to disconnect after a day or so. Less of an issue in Debian 9, and seemingly fixed by upgrading the kernel to a custom one. And the kernel is actually one of the things where you can save heaps of space when you do it yourself. The kernel package itself is 8.4MB for this one. The headers are 7.4MB. The stock kernels on the other hand (4.19 at downstream revisions 9, 10 and 13) took up a whole GB of space combined. That is how much I've been able to remove, even from headless systems. The stock kernels are incredibly bloated for what they are.

Other than that, most of the data storage is done through NFS over WiFi, which is actually faster than what is inside this laptop (a CF card which I will get to later).

Now let's talk hardware. And at age 17, you can imagine that it has seen quite a bit of maintenance there. The easiest mod is probably the flash mod. These old laptops use IDE for storage rather than SATA. Now the nice thing about IDE is that it actually lives on to this very day, in CF cards. The pinout is exactly the same. So you can use passive IDE-CF adapters and plug in a CF card. Easy!

The next thing I want to talk about is the battery. And um.. why that one is a bad idea to mod. Finding replacements for such old hardware.. good luck with that. So your other option is something called recelling, where you disassemble the battery and, well, replace the cells. The problem is that those battery packs are built like tanks and the disassembly will likely result in a broken battery housing (which you'll still need). Also the controllers inside those battery packs are either too smart or too stupid to play nicely with new cells. On that laptop at least, the new cells still had a perceived capacity of the old ones, while obviously the voltage on the cells themselves didn't change at all. The laptop thought the batteries were done for, despite still being chock full of juice. Then I tried to recalibrate them in the BIOS and fried the battery controller. Do not try to recell the battery, unless you have a spare already. The controllers and battery housings are complete and utter dogshit.

Next up is the display backlight. Originally this laptop used to use a CCFL backlight, which is a tiny tube that is driven at around 2000 volts. To its controller go either 7, 6, 4 or 3 wires, which are all related and I will get to. Signs of it dying are redshift, and eventually it going out until you close the lid and open it up again. The reason for it is that the voltage required to keep that CCFL "excited" rises over time, beyond what the controller can do.

So, 7-pin configuration is 2x VCC (12V), 2x enable (on or off), 1x adjust (analog brightness), and 2x ground. 6-pin gets rid of 1 enable line. Those are the configurations you'll find in CCFL. Then came LED lighting which required much less power to run. So the 4-pin configuration gets rid of a VCC and a ground line. And finally you have the 3-pin configuration which gets rid of the adjust line, and you can just short it to the enable line.

There are some other mods but I'm running out of characters. Why am I telling you all this? The reason is that this laptop doesn't feel any different to use than the ThinkPad x220 and IdeaPad Y700 I have on my desk (with 6c12t, 32G of RAM, ~1TB of SSDs and 2TB HDDs). A hefty setup compared to a very dated one, yet they feel the same. It can do web browsing, I can chat on Telegram with it, and I can do programming on it. So, if you're looking for a hobby project, maybe some kind of restrictions on your hardware to spark that creativity that makes code better, I can highly recommend it. I think I'm almost done with this project, and it was heaps of fun :D

HO. LY. SHIT.

So this gig I got myself into, they have a whitelist of IP addresses that are allowed to access their web server. It's work-at-home. We just got a new internet provider, and it looks like I get a different public IP address everytime I disconnect and connect to the WIFI. And since it looks like the way they work on their codebase is that you either edit the files right on the server or you download the files that you need to work on, make the changes, and then re-upload the file back to the server and refresh the website to see the changes, now I can't access the server because I get different IP addresses. And it's highly inconvenient to keep emailing them to add IP addresses to the whitelist.

No source control, just straight-up download/upload from/to the server. Like, srsly. So that also means debugging is extremely hard for me because one, they use ColdFusion and I've never used that shit before and two, how the hell do you debug with this style of work?

I just started this last Tuesday, and I already want to call it quits. This is just a pain in the ass and not worth my time. I'll be glad to just go back to driving Lyft/Uber to make money while I look for a full-time, PROPER job.

By the way, can I do that to a contracting job? Just call it quits when you haven't even finished your first task? How does this work?

Someone just rang the IT Helpdesk moaning that outlook wasn't syncing his mail and it was because the brand new laptop he's just gotten is crap.

So first, the guy on the helpdesk asked to log into the users laptop to look at outlook.
He apparently isn't at his laptop and doesn't have time for anyone to log in!
Wtf lol
So he rings back 10 mins later when at his laptop but wont let the helpdesk log in as he has 'confidential' documents open.

Wtf, close them, why are you ringing us to look at your laptop if you won't let us log on?? lol

So helpdesk was like ok, just check cat cable is plugged in, check wifi is off, do a send/receive etc. and the user's like yes, they're all okay!

Helpdesk tells him to reboot his pc. He does so.
Doesn't resolve it.
Skip forward another 10 painful minutes while the helpdesk guy is pulling his hair out checking everything in the background, and all looks fine.

User then says "should i also turn off my iPhone?"
Helpdesk: 'No, outlook is just on your laptop'.
User: 'No *assured laugh* its on my phone too. I get emails there too'
Helpdesk: 'No, you use the generic 'Mail' app on your phone. Outlook is a separate app. We don't use it.'
User: 'But you're not listening, regardless of the app name, that's my problem, mail's not working on my phone'.
Helpdesk: '.....so why didn't you say so 20 minutes ago when i asked to log into ur laptop?'

User: 'Didn't think it was relevant. Laptop was fine. Assumed you'd know'.

...........

Why.

Why???

Why.

Shockingly, a phone restart fixed it. The user couldn't remember the last time he'd turned the thing off.

Storytime
A story about an Android TVbox which decided to become an iPad

Several years ago we've bought an android tv-box. 

It served me and my family well for several years.

Specs are not that important in this story, but there they are:

Android 4.4 
1GB RAM
Amlogic quadcore 1.4HGz
8GB memory.

This device served us well - online TV, browsing, music, file sharing and so on. But recently cheap Chinese memory deciteed to take a break and damaged ROM. Because of that device won't boot. The only option was to take it apart and "short circuit" certain legs on memory chip and make it boot from SD card and install new firmware. After such operations tv-box worked well again. 

Hoverer, memory glitched again and again and this algorithm was repeated for several months.

But that is not what is this story about.

One day memory went completely crazy and there was no way to install new firmware on it. It just hanged on install. (BTW, it was official firmware for this device)

But after countless attempts it finally worked! It installed the firmware and booted into launcher and connected to WiFi! 

But now comes the most interesting part. 

It was not android anymore.

It decided to became an iPad.

My dad logged in to his Google account via tv-box and got mail that someboby connected from our IP via iPad (we don't have an iPad) and using safari browser! Stock browser is not safari browser.....

"Ok, nvm, crazy glitch." - we thought.

But preinstalled play marked wont launch. Because he told us, that we're trying to connect from iPad.

And Google chrome page suggested to download chrome for iPad

And everything was acting like it is an iPad.

OK, downloaded iTunes, why not??? ._.

Tried to install elixir for android via apk from flash, but then memory glitched one more time, everything went black and tv-box had damaged ROM again...

After that we decided to not torment it anymore...

That's it. Poor Android TVbox that all his life dreamed to become an iPad. Rest in peace.

Prologue
My dad has an acquaintance - let's call him Tom. Tom is an gynecologist, one of the best in Poznań, where I live. He's a great guy but absolutely can not into tech of any kind besides his iPhone and basic PC usage. For about a year now I've been doing small jobs for him - build a new PC for his office, fix printer, fix wifi, etc. He has made a big mistake few years ago by trusting a guy, let's call him Shitface, with crating him software for work. It's supposed to be pretty simple piece of code in which you can create and modify patient file, create prescription from drugs database and such things. This program is probably one of the worst pierces of code I've ever seen and Shitface should burn for that. Worse, this guy is pretentious asshole lacking even basic IT knowledge. His code is garbage and it's taking him few months to make small changes like text wrapping. But wait, there's more. Everything is hardcoded so every PC using this software must have installed user controls for which he doesn't have license and static IP address on network card.
Part 1
Tom asked me to build him a new PC that will be acting like a server for Shitface's program. He needs it in Kalisz (around 150 km from my place). I Agred (pun intended) and after Tom brought me his old computer I've bought parts and built a new one. I have also copied everything of value and everything took me around three hours.
Part 2
Everything was ready but Shitface's program. I didn't know much about it's configuration so when I've noticed that it's not working even on the old PC I got a bit worried. Nevertheless I started breaking everything I know about it and after next three hours I've got it somewhat working. Seeing that there's still some problems with database connection (from Windows' Event Viewer) I wrote quick SMS to Shitface asking what can be wrong. He replied that he won't be able to help me any way until Monday (day after deadline). I got pissed and very courteously asked him for source code because some of libraries used in this project has license that requires either purchase of commercial license or making code open source. He replied within few minutes that he'll be able to connect remotely within next 10 minutes. He was trying to make it work for the next hour but he succeeded. It was night before deadline so I wrapped everything up and went to bed thinking that it won't take me more than an hour to get this new PC up and running in the office. Boy was I wrong.
Also, curious about his code, I've checked source and he is using beautiful ponglish (mixed Polish and English) with mistakes he couldn't even bother to fix. For people from Poland, here's an example:
TerminarzeController.DeleteTerminarzShematyDlaLekarza
Part 3
So I drove to Kalisz and started working on making everything work. Almost everything was ready so after half an hour I was done. But I wanted to check twice if it's all good because driving so far second time would be a pain. So I started up Shitface's program, logged in, tried to open ANYTHING and... KABUM. UNHANDLED EXCEPTION. WTF. I checked trace and for fuck sake something was missing. Keep in mind that then I didn't know he's using some third party control for Windows Forms that needs to be installed on client PC. After next fifteen minutes of googling I've found a solution. I just had to install this third party software and everything will work. But... It had to be exactly this version and it was old. Very old. So old that producent already removed all traces of its existence from their web page and I couldn't find it anywhere. I tried installing never version and copying files from old PC but it didn't work. After few hours of searching for a solution I called Mr Shitface asking him for this control installation file. He told me that he has it but will be able to send it my way in the evening. Resigned I asked for this new PC to be left turned on and drove home. When he sent me necessary files I remotely installed them and everything started working correctly.
So, to sum it up. Searching for parts and building new PC, installing OS and all necessary software, updating everything and configuring it for Tom taste took me around what, 1/3 of time I spent on installing Mr Shitface's stupid program which Tom is not even happy with. Gotta say it was one of worst experiences I had in recent months. Hope I won't have to see this shit again.
Epilogue
Fortunately everything seems to work correctly. Tom hasn't called me yet with any problems. Mission accomplished. I wanna kill very specific someone. With. A. Spoon.

Paranoid Developers - It's a long one
Backstory: I was a freelance web developer when I managed to land a place on a cyber security program with who I consider to be the world leaders in the field (details deliberately withheld; who's paranoid now?). Other than the basic security practices of web dev, my experience with Cyber was limited to the OU introduction course, so I was wholly unprepared for the level of, occasionally hysterical, paranoia that my fellow cohort seemed to perpetually live in. The following is a collection of stories from several of these people, because if I only wrote about one they would accuse me of providing too much data allowing an attacker to aggregate and steal their identity. They do use devrant so if you're reading this, know that I love you and that something is wrong with you.

That time when...

He wrote a social media network with end-to-end encryption before it was cool.

He wrote custom 64kb encryption for his academic HDD.

He removed the 3 HDD from his desktop and stored them in a safe, whenever he left the house.

He set up a pfsense virtualbox with a firewall policy to block the port the student monitoring software used (effectively rendering it useless and definitely in breach of the IT policy).

He used only hashes of passwords as passwords (which isn't actually good).

He kept a drill on the desk ready to destroy his HDD at a moments notice.

He started developing a device to drill through his HDD when he pushed a button. May or may not have finished it.

He set up a new email account for each individual online service.

He hosted a website from his own home server so he didn't have to host the files elsewhere (which is just awful for home network security).

He unplugged the home router and began scanning his devices and manually searching through the process list when his music stopped playing on the laptop several times (turns out he had a wobbly spacebar and the shaking washing machine provided enough jittering for a button press).

He brought his own privacy screen to work (remember, this is a security place, with like background checks and all sorts).

He gave his C programming coursework (a simple messaging program) 2048 bit encryption, which was not required.

He wrote a custom encryption for his other C programming coursework as well as writing out the enigma encryption because there was no library, again not required.

He bought a burner phone to visit the capital city.

He bought a burner phone whenever he left his hometown come to think of it.

He bought a smartphone online, wiped it and installed new firmware (it was Chinese; I'm not saying anything about the Chinese, you're the one thinking it).

He bought a smartphone and installed Kali Linux NetHunter so he could test WiFi networks he connected to before using them on his personal device.

(You might be noticing it's all he's. Maybe it is, maybe it isn't).

He ate a sim card.

He brought a balaclava to pentesting training (it was pretty meme).

He printed out his source code as a manual read-only method.

He made a rule on his academic email to block incoming mail from the academic body (to be fair this is a good spam policy).

He withdraws money from a different cashpoint everytime to avoid patterns in his behaviour (the irony).

He reported someone for hacking the centre's network when they built their own website for practice using XAMMP.

I'm going to stop there. I could tell you so many more stories about these guys, some about them being paranoid and some about the stupid antics Cyber Security and Information Assurance students get up to. Well done for making it this far. Hope you enjoyed it.

Fucking windows! I am so fucking done with this microsoft bullshit!

Hear me out here, i am a gamer. I need windows because it has the games (and software to aid those games) unlike any other platform. But windows 10 is basically already phishing andmalware at this point. I stuck to win 7 because it had a start menu and didn't totally drive me up the wall.

Just a short list of their bullshits: ads in the explorer window, ads in your taskbar reminders, data mining like it is nobodies business and trying to hide it, sharing my wifi access with friends (wtf), the fucking retarded new start menu, the crappy fullscreen apps which have less functionality than the actual proper desktop applications that you need to config what you want, and even then pushing multiple updates that simply broke peoples pc's. Fuck that, ill stick to 7.

They are making win10 worse by the week making it unlikely i will ever join that hell, and they are also aiming to force me there. Making windows store exclusives and dx12 only games. What am i supposed to do against that?! The current releases don't bother me much but fuck i figure it is a matter of time until the newest katamari game is their exclusive and i nanananana katamari damacy all over their platform.

And well all alternative os's are just out of the question unless vulkan rendering gets the upper hand. Then i'd switch to whatever stable distro and learn about our new penguin based overlords languages.

For now i will just stick to win7, suck on my thumb while in fetal position and hope it just all goes away.

One year for Christmas, my dad got me an old tower and installed Windows 98 on it. He also got two old-school PCI WiFi cards so that my "new" computer could access the Internet via his.

I started learning basic web development. I would convince my mom (an English teacher) to buy me books on programming all the time when she was getting her own books at the store.

Eventually, I got a book on Blitz Basic and started making my own video games.

Then GameMaker, Java, C/C++, and more web development and design happened until all the sudden, out of nowhere, I'm a computer scientist 😁

It's crazy how much we owe to our parents. And neither us nor them even realized what they were doing at the time!

I haven't ranted for today, but I figured that I'd post a summary.
A public diary of sorts.. devRant is amazing, it even allows me to post the stuff that I'd otherwise put on a piece of paper and probably discard over time. And with keyboard support at that <3

Today has been a productive day for me. Laptop got restored with a "pacman -Syu" over a Bluetooth mobile data tethering from my phone, said phone got upgraded to an unofficial Android 9 (Pie) thanks to a comment from @undef, etc.

I've also made myself a reliable USB extension cord to be able to extend the 20-30cm USB-A male to USB-C male cord that Huawei delivered with my Nexus 6P. The USB-C to USB-C cord that allows for fast charging is unreliable.. ordered some USB-C plugs for that, in order to make some high power wire with that when they arrive.

So that plug I've made.. USB-A male to USB-A female, in which my short USB-C to USB-A wire can plug in. It's a 1M wire, with 18AWG wire for its power lines and 28AWG wires for its data lines. The 18AWG power lines can carry up to 10A of current, while the 28AWG lines can carry up to 1A. All wires were made into 1M pieces. These resulted in a very low impedance path for all of them, my multimeter measured no more than 200 milliohms across them, though I'll have to verify and finetune that on my oscilloscope with 4-wire measurement.

So the wire was good. Easy too, I just had to look up the pinout and replicate that on the male part.

That's where the rant part comes in.. in fact I've got quite uncomfortable with sentences that don't include at least one swear word at this point. All hail to devRant for allowing me to put them out there without guilt.. it changed my very mind <3

Microshaft WanBLowS.

I've tried to plug my DIY extension cord into it, and plugged my phone and some USB stick into it of which I've completely forgot the filesystem. Windows certainly doesn't support it.. turns out that it was LUKS. More about that later.

Windows returned that it didn't support either of them, due to "malfunctioning at the USB device". So I went ahead and plugged in my phone directly.. works without a problem. Then I went ahead and troubleshooted the wire I've just made with a multimeter, to check for shorts.. none at all.

At that point I suspected that WanBLowS was the issue, so I booted up my (at the time) problematic Arch laptop and did the exact same thing there, testing that USB stick and my phone there by plugging it through the extension wire. Shit just worked like that. The USB stick was a LUKS medium and apparently a clone of my SanDisk rootfs that I'm storing my Arch Linux on my laptop at at the time.. an unfinished migration project (SanDisk is unstable, my other DM sticks are quite stable). The USB stick consumed about 20mA so no big deal for any USB controller. The phone consumed about 500mA (which is standard USB 2.0 so no surprise) and worked fine as well.. although the HP laptop dropped the voltage to ~4.8V like that, unlike 5.1V which is nominal for USB. Still worked without a problem.

So clearly Windows is the problem here, and this provides me one more reason to hate that piece of shit OS. Windows lovers may say that it's an issue with my particular hardware, which maybe it is. I've done the Windows plugging solely through a USB 3.0 hub, which was plugged into a USB 3.0 port on the host. Now USB 3.0 is supposed to be able to carry up to 1A rather than 500mA, so I expect all the components in there to be beefier. I've also tested the hub as part of a review, and it can carry about 1A no problem, although it seems like its supply lines aren't shorted to VCC on the host, like a sensible hub would. Instead I suspect that it's going through the hub's controller.

Regardless, this is clearly a bad design. One of the USB data lines is biased to ~3.3V if memory serves me right, while the other is biased to 300mV. The latter could impose a problem.. but again, the current path was of a very low impedance of 200milliohms at most. Meanwhile the direct connection that omits the ~200ohm extension wire worked just fine. Even 300mV wouldn't degrade significantly over such a resistance. So this is most likely a Windows problem.

That aside, the extension cord works fine in Linux. So I've used that as a charging connection while upgrading my Arch laptop (which as you may know has internet issues at the time) over Bluetooth, through a shared BNEP connection (Bluetooth tethering) from my phone. Mobile data since I didn't set up my WiFi in this new Pie ROM yet. Worked fine, fixed my WiFi. Currently it's back in my network as my fully-fledged development host. So that way I'll be able to work again on @Floydian's LinkHub repository. My laptop's the only one who currently holds the private key for signing commits for git$(rm -rf ~/*)@nixmagic.com, hence why my development has been impeded. My tablet doesn't have them. Guess I'll commit somewhere tomorrow.

(looks like my rant is too long, continue in comments)

Have a couple I want to air today.

First was at my first gig as a dev, 4-5 months out of school. I was the only dev at a startup where the owner was a computer illiterate psycopath with serious temper tantrums. We're talking slamming doors, shouting at you while you are on the phone with customers, the works...

Anyways, what happened was that we needed to do an update in our database to correct some data on a few order lines regarding a specific product. Guess who forgot the fucking where-clause... Did I mention this boss was a cheap ass, dollar stupid, penny wise asshole that refused to have anything but the cheapest hosting? No backups, no test/dev/staging environment, no local copies... Yeah, live devving in prod, fucking all customers with a missing semi-colon (or where clause).

Amazingly, his sheer incompetance saved my ass, because even if I explained it, he didn't get it, and just wanted it fixed as best we could.

The second time was at a different company where we were delivering managed network services for a few municipalities. I was working netops at that time, mostly Cisco branded stuff, from Voice-over-IP and wifi to switches and some routing.

One day I was rolling out a new wireless network, and had to add the VLAN to the core switch on the correct port. VLAN's, for those who don't know, are virtual networks you can use to run several separated networks on the same cable.

To add a VLAN on a Cisco switch one uses the command:

switchport access vlan add XYZ

My mistake was omitting the 'add', which Cisco switches happily accept without warning. That command however can be quite disruptive as it replaces all of the excisting VLAN's with the new one.

Not a big deal on a distribution switch supplying an office floor or something, but on a fucking core switch in the datacenter this meant 20K user had no internet, no access to the applications in the DS, no access to Active Directory etc. Oh and my remote access to that switch also went down the drain...

Luckily a colleague of mine was on site with a console cable and access to config backups. Shit was over within 15 minutes. My boss at that time was thankfully a pragmatic guy who just responded "Well, at least you won't make that mistake again" when we debriefed him after the dust settled.

tl;dr:
The Debian 10 live disc and installer say: Heavens me, just look at the time! I’m late for my <segmentation fault

—————

tl:
The Debian 10 live cd and its new “calamares” installer are both complete crap. I’ve never had any issues with installing Debian prior to this, save with getting WiFi to work (as expected). But this version? Ugh. Here are the things I’ve run into:

Unknown root password; easy enough to get around as there is no user password; still annoying after the 10th time.

Also, the login screen doesn’t work off-disc because it won’t accept a blank password, so don’t idle or you’ll get locked out.

The lock screen is overzealous and hard-locks the computer after awhile; not even the magic kernel keys work!

The live disc doesn’t have many standard utilities, or a graphical partition editor. Thankfully I’m comfortable with fdisk.

The graphical installer (calamares) randomly segfaults, even from innocuous things like clicking [change partition] when you don’t have a partition selected. Derp.

It also randomly segfaults while writing partitions to disk — usually on the second partition.

It strangely seems less likely to segfault if the partitions are already there, even if it needs to “reformat” (recreate) them.

It also defaults to using MBR instead of GPT for the partition table, despite the tooltip telling you that MBR is deprecated and limited, and that GPT is recommended for new systems. You cannot change this without doing the partitions manually.

If you do the partitions manually and it can’t figure out where to install things, it just crashes. This is great because you can’t tell it where to install things, and specifying mount points like /boot, /, and /home don’t seem to be enough.

It also tries installing 32bit grub instead of 64bit, causing the grub installer to fail.

If you tell it to install grub on /boot, it complains when that partition isn’t encrypted — fair — but if you tell it to encrypt /boot like it wants you to, it then tries installing grub on the encrypted partition it just created, apparently without decrypting it, so that obviously fails — specific error: cannot read file system.

On the rare chance that everything else goes correctly, the install process can still segfault.

The log does include entries for errors, but doesn’t include an error message. Literally: “ERROR: Installation failed:” and the log ends. Helpful!

If the installer doesn’t segfault and the install process manages to complete, the resulting install might not even boot, even when installed without any drive encryption. Why? My guess is it never bothered to install Grub, or put it in the wrong place, or didn’t mark it as bootable, or who knows what.

Even when using the live disc that includes non-free firmware (including Ath9k) it still cannot detect my wlan card (that uses Ath9k).

I’ve attempted to install thirty plus times now, and only managed to get a working install once — where I neglected to include the Ath9k firmware.

I’m now trying the cli-only installer option instead of the live session; it seems to behave at least. I’m just terrified that the resulting install will be just as unstable as the live session.

All of this to copy the contents of my encrypted disks over so I can use them on a different system. =/

I haven’t decided which I’m going with next, but likely Arch, Void, or Gentoo. I’d go with Qubes if I had more time to experiment.

But in all seriousness, the Debian devs need some serious help. I would be embarrassed if I released this quality of hot garbage.

(This same system ran both Debian 8 and 9 flawlessly for years)

Boss: ABC
Me: as an intern at XYZ firm.

ABC: this is internet is very slow today, AmanDeep what happen check it.

me: Sir,there are too much user on the wifi.

ABC:So how we can disconnect them without their knowing.

me: We have to deauth all of their connection using fluxion.

ABC: Do it fast...
me: its take time to be done, you have to do by linux.

ABC: I had done it before in my high school on cmd you and your excuses for the work.You are lame at work...
...\../..
\......../
Me: Now i am searching a new internship...

I think I want to quit.

I know it’s a bit of an inconvenient time with there being corona around but everything was okay up till January. I’m a junior even though I shouldn’t be. Since my manager told me and my team leader senior in my review “maybe you two should switch jobs” things have been going downhill. I think the team lead had it out for me and didn’t put me on a new project, I’ve been left with doing stupid basic shit like updating text on websites in a cms and doing fuck all and then there’s also another guy that was basically harassing me trying to put me in my place any time I was doing better than him and literally both of them been like that ... and now that I’m working from home it’s even worse. I don’t have any kind of assurance that everything okay and actually I think I’m being framed as welll since I found keyloggers on my work laptop and deleted cleaned shit up the past two weeks and changed my WiFi security as there were like 5 unknown devices on our network so yeah .. I’ve been framed and they made it out like I put a powershell script on one of the servers and it crashed a Porsche website for 8 h and all kinds of bullshit - this was yday. On Tuesday they logged me out of everything like changed the password for work vpn and kicked me out of slack and Microsoft teams for over 2 hours till the end of shift and two managers weren’t answering their phone and then next day my manager called and apologised that saying that he “accidentally” did that to me along with 15 people they let go from the company....

I’m seriously thinking of quitting being removed from team group for a moment , not being on a project and people literally trying to put me down after I know I’m genuinely smarter than them and if I had over 10 years experience like those on my team (I have 1) I’d be far higher up and better

They can genuinely just go fuck themseves !!!! And here I was going to work over weekend on something! No fucking way I just wanna quit or give in my notice but because of corona I’m divided

I’ve had enough of shitty ISPs. Time to shame them 😈

Here in the UK, we have a company called TalkTalk who treat their customers as whores by not giving a shit and taking all their money.

I have had an ongoing issue for about 9 months now where our internet is more unstable, but also slower. We pay for 72Mbps at which we used to get, but now our internet tops out at 30Mbps if we are lucky. It can be 20Mbps one minute and 7Mbps the next, and I’ve had it drop below 1Mbps for no goddam reason.

I’ve spoken (well, argued) argued to their so called customer service department over phone and live chat explaining the situation and all they’ve done is said “restart your router”, or “we’ll send out a new router, it’s probably a WiFi issue”, or some bullshit like “I’ve ‘changed’ something on my end”. On one conversation with a so called technician, I had to explain how networking actually worded, and and even called a 7Mbps acceptable when we were paying for 10x that!!!!!

The thing that makes it worse is they actually have systems that detect any issues with customers internet lines, but they only alert the customer to the issue through an online portal, telling the customer to call up and get it dealt with rather than passing the info to a tech department and having issues fixed without the customer knowing unless it’s absolutely necessary.

So 9 months in and I still have a fluctuating, unstable internet connection which is slow and overpriced with no tunnel in sight. GIVE ME BACK MY GODDAMN MONEY YOU FUCKING THIEVING BASTARDS.

It’s really painful how non technical people think all technical stuff is the same.

The amount of times I’ve been brought in to help someone with a printer or WiFi network.

I didn’t do a computer science degree for this.

I’m also pretty sure my last two bosses think fixing the printer is the same as creating large scale systems.

My last boss wanted me to build a Vr chatbot despite spending the last few years building web servers and react/redux apps. I mean I can probably figure it out and it’ll be fun, but don’t think I’m gonna get this done in a week with all my other responsibilities too.

My new boss wants me to singlehandedly build a massive marketplace system that would probably take a team of ten, several years.

Fed up of being around non technical managers who don’t listen to me with my feedback.

Time for a new chapter in the new year.

Samsung Smart TV becomes Samsung Dumb TV.

Welcome back dear readers, to the next installment of my Raspberry Pi / Pi Hole / MitM box adventure!

For those of you who are new to this story, I'm a long experience programmer who knows very little about his home network or networking in general and has constantly been going over his 250GB data plan because 'rona, and thus, wants answers to "where is the data going".

So, I got the Pi, codenamed Mini-Beowolf, positioned between the modem and router... worked some fuckin systemd.networkd magic (which was sort of easy... but was hard cause I'm new to it) and viola, this son of a bitch passes through the ethernet and doesn't even show up on the router. Fu-King Beastly, I love it.

Now to static IP all my devices so I fire up my trusty TP-Link admin portal. I should add here... I've visited this admin about a total of 10 minutes prior to this when I set this wifi router up and just let it do DHCP.

So I'm getting to know my admin portal... I've got most of my devices connected to reserved IPs... and I find this one fuckin device reporting as "localhost".

Now, I've got a MAMP install... but it hasn't been running. But still I thought for sure it was just MAMP run a bit amok.

But no... it was my fucking Samsung "Smart" TV. That piece of shit is, and apparently has been reporting its device name as, sure as shit, fucking "localhost"... PROBABLY FOR YEARS.

Now, IDK how that didn't cause me any major problems over the years, and I read quite a few forums about people who it did mess up their network. So I resolved to rename the Samsung TV device.

I found the spot in the network settings of the TV... I changed the name from the pick list of rooms in a house like "Living Room" and "Bed Room", then I tried entering my own device name. But no matter what I picked, or no matter how many times I restarted/reset that TV the network name is ALWAYS "localhost".

Even though somehow my network survived this long... I'm not standing for that shit.

My Samsung TV is now blocked COMPLETELY at the router level. (After I ran one last factory reset and update)

The kicker? That Pi I built has a Samsung SSD... so I'm blocking Samsung WITH FUCKING SAMSUNG.

Needless to say, these are likely among my last Samsung purchases.

Join me next time when I FINALLY try to turn Pi Hole on and then get a tcpdump (or some other lesser output from the tcp stream) going.

About slightly more than a year ago I started volunteering at the local general students committee. They desperately searched for someone playing the role of both political head of division as well as the system administrator, for around half a year before I took the job.

When I started the data center was mostly abandoned with most of the computational power and resources just laying around unused. They already ran some kvm-hosts with around 6 virtual machines, including a cloud service, internally used shared storage, a user directory and also 10 workstations and a WiFi-Network. Everything except one virtual machine ran on GNU/Linux-systems and was built on open source technology. The administration was done through shared passwords, bash-scripts and instructions in an extensive MediaWiki instance.

My introduction into this whole eco-system was basically this:
"Ever did something with linux before? Here you have the logins - have fun. Oh, and please don't break stuff. Thank you!"

Since I had only managed a small personal server before and learned stuff about networking, it-sec and administration only from courses in university I quickly shaped a small team eager to build great things which would bring in the knowledge necessary to create something awesome. We had a lot of fun diving into modern technologies, discussing the future of this infrastructure and simply try out and fail hard while implementing those ideas.

Today, a year and a half later, we look at around 40 virtual machines spiced with a lot of magic. We host several internal and external services like cloud, chat, ticket-system, websites, blog, notepad, DNS, DHCP, VPN, firewall, confluence, freifunk (free network mesh), ubuntu mirror etc. Everything is managed through a central puppet-configuration infrastructure. Changes in configuration are deployed in minutes across all servers. We utilize docker for application deployment and gitlab for code management. We provide incremental, distributed backups, a central database and a distributed network across the campus. We created a desktop workstation environment based on Ubuntu Server for deployment on bare-metal machines through the foreman project. Almost everything free and open source.

The whole system now is easily configurable, allows updating, maintenance and deployment of old and new services. We reached our main goal for this year which was the creation of a documented environment which is maintainable by one administrator.

Although we did this in our free-time without any payment it was a great year with a lot of experience which pays off now.

Well my router just died 😥 she was the best wifi in the LAN, you will be missed.

Here, a full retrospective of my Apple products ownership.

iPhone SE – after Android, I was absolutely amazed by how fast it worked. No UI lags, camera works absolutely instantly no matter the light conditions, all the GPU-heavy games work butter smooth.

After camera and charging port failures on Xperia flagship and CPU literally melting through screen rendering it unusable on Meizu, it was enough to make me interested in Apple products.

When I was using Meizu, I actually got a twitching eye which was triggered by UI lags. After two months of using iPhone, I noticed that something was missing – my eye wasn't twitching anymore.

iPhone actually cured me.

MacBook 12 – a 900 grams laptop with passive-cooled mobile CPU running many Chrome tabs, heavy Webpack HMR build, VSCode and Slack just fine. Yes, you can't play games, but I don't even require it from a laptop this tiny.

Butterfly keyboard that internet hates so much actually increased my typing speed and comfort compared to MX Red mechanical keyboard, and ForceTouch trackpad made me forget about mouse. I learned how to disassemble the Butterfly keyboard if I ever need this but the keyboard never failed.

I use this laptop to this day and it still even smells like the day one, a beautiful smell of a new Apple product.

iPhone X – got it because of the camera, stayed for great battery life and amazing OLED display. I use telephoto lens exclusively and it made me lay off my Canon DSLR with Helios lens which stays on my bookshelf covered in dust to this day.

True black of OLED display which is undistinguishable from the screen bezel is stunning. To this day, battery surely works for one and a half days and I watch youtube really often.

I sometimes struggled to unlock iPhone SE with wet fingers, but with FaceID, as soon as I look at the screen the phone is unlocked. Works perfect every time, never had an issue with this.

Stainless steel body feels premium compared to aluminum. Stereo sound is a major selling point if you're like watching videos and playing games on your phone. Overall amazing product and a huge improvement over SE.

Apple Watch series 4 – really comfortable fit. Nice battery life, once I forgot about it for like ten days during lockdown and it was still working, even though on power reserve mode. Really reliable in terms of battery life and liquid protection. Very satisfying Taptic Engine crown clicks. I run every day and Apple watch always measure my heart rate correctly, and the running app is well designed and a pleasure to use. Overall a nice accessory to have if you use iPhone.

Powerbeats Pro – great sound and battery life. I switched from Shure SE215 which was great, but it had wires. I listen to a lot of music so the sound quality is important for me. When I was choosing earphones I visited a store where you can listen to them all. I listened through earphones like Noble Audio Kaiser Encore and JH Audio Layla, and of course $4000 Laylas sound better than $249 bluetooth earphones, but the difference in sound doesn't justify the difference in price to me.

Powerbeats pro is the Apple H1 chip true wireless earphones with largest driver of them all which makes them sound better than AirPods Pro – it's just physics. Bass in Powerbeats is amazing, which is also true for my Shures, but Powerbeats also win in clarity.

It connects seamlessly to both my MacBook and my iPhone, and everyone in voice chats can hear me really good.

Huge case is a major throwback compared to AirPods, but the battery life of earphones themselves is so great that I just leave the case at home and only carry earphones and it works for me.

Apple Link bracelet in space black – really better than I expected. Intricate detailing, literally the steel that Rolex uses, top-notch finishing and polishing – all that for just 450 dollars. I only used it for several days now, but it already feels like a really satisfying product.

Before all that I was using Linux. It took a year for elementaryos devs to fix wifi for my laptop. Ubuntu looks and feels ugly. Pop OS felt like garbage. Manjaro was also just that – garbage. KDE Plasma – I don't even want to talk about that. A monstrocity where you accidentally click a wrong switch in the settings and your system won't boot up again. Also, PulseAudio. Struggles with proprietary drivers and software updates.

Windows? I serviced a lot of Windows PCs through my career and it never, never worked as intended. I'm no dumbass, I always managed the rights correctly and never installed sketchy apps. My latest ryzen gaming build with a lot of ram also lags somehow even in Windows 10 UI.

Before I switched, I defended Linux.

My life was a lie.

I'm sorry to everyone who I offended based on their opinion on Linux.

Fk you Google!

My Samsung note 10 screen went dead near a week ago... it's a secondary line so waiting for parts wasn't the end of the world.

Ofc the screen (curved and incl a fingerprint reader thatd be a major pain to not replace) was integrated to the whole front half... back panel glued, battery, glued immensely and with all other parts out, about 6mm space only at the bottom to get a tool in to pry it out.

New screen (off brand) ~200... all genuine parts amazon refurb ~230... figured id have some extra hardware for idk what... i like hardware and can write drivers so why not.

Figured id save a bit of time and avoid other potentially damaged (water) components to just swap out the mobo unit that had my storage.

Put it back together, first checked that my sim was recognised since this carrier required extraneous info when registering the dev... worked fine... fingerprint worked fine, brave browser too...

Then i open chrome. It tells me im offline... weird cuz i was literally in a discord call. My wifi says connected to the internet (not that i wouldn't have known the second there was a network issue... i have all our servers here and a /28 block... ofc i have everything scripted and connected to alert any dev i have, anywhere i am, the moment something strange happens).

Apparently google doesnt like the new daughter board(i dislike the naming scheme... its weird to me)... so anything that is controlled by google aside from the google account that is linked to non-google reliant apps like this... just hangs as if loading and/or says im offline.

I know... itll only take me about the 5-10m it took to type this rant but ffs google... why dont you even have an error message as to what your issue is... or the simple ability to let me log in and be like 'yup it's me, here's your dumb 2fa and a 3rd via text cuz you're extra paranoid yet dont actually lock the account or dev in any way!'

I think it's a toss up if google actually knows that it's doing this or they just have some giant glitch that showed up a couple times in testing and was resolved via the methods of my great grama- "just smack it or kick it a few times while swearing at it in polish. Like reaaaally yelling. Always worked for me! If not, find a fall guy."

## building my own router

I hoped things would go more smoothly :)
Anyway, my new miniPC easily accepted CentOS 8 - no fuss here. And I've got to say - I love CentOS8 so far! Shell has amazing nifty tricks, UI (gnome3) is also snappy, video/audio/ethernet,.. everything works.

What I did NOT expect is hardware being off. Well okay, the price was low - it was obvious smth is not right. But still.. I decided to build my own router so that I could swap wifi card whenever I want. So that I could run my own network services in there. Turns out - the card swapping is not as easy as one might think.

I got the AX200 WiFi6 card for that very purpose. But once plugged in the OS can only see it's bluetooth module. Weird... What's even weirder is that even though the card is PCIe, the OS uses btusb module to talk to that device. What? USB?? emm.. What??

And there it is. After opening it up again I noticed that the mPCIe area is marked with a label: "USB WIFI / WWAN". USB? Does that mean this PCIe slot is wired into the USB bus? Not impossible I guess.

Googling for a "pcie wifi over usb" or smth like that brought me to one reddit (I think?) where someone wanted to build a DIY wifi mPCIe -> USB adapter and someone else adviced hime that (for some reason) at best he could only get bluetooth working (hey! just like me!). It's got to do smth with pcie channels and USB being too weak to handle all that load, or smth.. IDK, I'm not a HW guy.

Well that sucks then! I have a mPCIe slot that does not work as a PCIe. Shit! So I guess the best I could do is to plug back in the same wifi card that came with the device. It smells like 2003 - supports only g protocol. Fine, let's try that. Maybe I'll find a way to work around this mPCIe limitation later on (USB adapter or smth... except there are no USB WIFI6 dongles yet :( ). So I plug it back in and start turning it into a router. Disable NetworkManager, configure static NCs' settings, install dhcpd, hostapd, bind and others. Looks like all is done! Now it's time to start it all. systemctl start hostapd --> FAILED. wtf? journalctl says it could not initialize a driver. umm okay? Why? Forums say I should airodump-ng check and kill whatever's using that device. Fine. airodumo reveals avahi and wpa_suppl are still using it. kill, kill, GOTTA KILL 'EM ALL!! Starting hostapd again -- same shit... wtf?

iw list

My gawd... That shitty network card does not even support AP mode :( I mean.. My USB wifi dongle for 2€ supports 2x more modes, is faster, has better range and is easier to work with than this old tart!

Yeah. That was an interesting day. When enfironment engineers break my testing environments at work I'm glad I have where to spend my time now.

BTW any ideas how to bypass this mPCIe nonsense? Come on, there are USB GPUs out there.. Why can't they make a USB (or dual-USB if they really need to) mPCIe adapter?

I have never understood people ranting about how Linux is incompatible with their machines. Back in 2006 what ever machine I had tried Linux on was working better with it. More than that all the drivers were working out of the box and the only problem that could possibly happen was with graphics.

FF 10 years. I am using MacBook for some time now and I did no installation of Linux for couple of years now except on bare metal servers. And have just bought my sister a new hp envy. Nothing fucking works. Not even wifi. Installation is hanging and I do not fucking know why! Her previous computer had problems with wifi. If wifi is turned on you could not turn the fucking pc off. It would fucking freeze.

Well fuck my life :(

Just found out that android looks for new SSIDs even when wifi is off...
Why does it do that?
Isn't that a waste of battery?
Well since I use the SSIDs of my company to save the time of entry and leaving I don't need to have wifi on now, but still... Why?

This shit is long story of my computer experience over my lifetime.

When I was young I got my first PC with windows it was not so bad. It required safe shut down of it’s fat32 partition. From time to time I needed to reinstall it cause of slow down but I got used to it I was only a gamer.

Time passes and I got more curious about computers and about this linux. Everything worked there but installation of anything was complete madness and none of windows programs worked well, and I wanted to play games and be productive so I sticked with windows.

I bought hp laptop once with nvidia card, it was overheating and got broken. So I bought toshiba and all I told to the seller was I want ATI card. Took me 5 minutes to do it and I was faster then my friend buying pack of cigarettes because I was earning money using computer.

Then I grown up running my small one person programming businesses and I wanted to run and compile every fucking program on this world. I wanted linux shell commands. I wanted package manager, and I wanted my os to be simple because I wasn’t earning money by using my os but by programming. So after getting my paycheck I bought mac. I can run windows and linux on vm if I need it. I try not to steal someones work so I didn’t want to run hackintosh. I am using this mac for some time.

Also I use playstation for gaming. Because I only want to run and play game I am not excited about graphics but gameplay. I think I am pragmatic person.

I can tell you something about my mac.
When I close lid it go sleep when I open it wakes up instantly. I never need to wonder if I want to hibernate or shut down or sleep and drain battery. It is fucking simple.
When I want to run or open something it doesn’t want me to wait but it gives me my intellij or terminal or another browser or whatever I search for. Yeah search is something that works.
Despite it got 8 gigs of ram I can run whatever number of programs I want at the same speed. The speed is not very fast sometimes but it’s constant fast.
I have a keychain so my passwords are in one place I can slow down shared internet speed, I can put my wifi in monitor mode and I don’t need to install some 3rd party software.
And now I updated my mac to high sierra, cause it’s free and I want to play with ios compilation. Before I did it I didn’t even backup whole work. I just used time machine and regular backups. And guess what, it still works at the same speed and all I did was click to run update and cook something to eat.
When I got bored I close the lid, when got idea open lid and code shit, not waiting for fucking wakeup or fucking updates.

I wanted to rant apple products I use but they work, they got fucking updates all along at the same time. And all of updates are optional.

I cannot tell that about all apple products but about products I use.

I think I just got old and started to praise my limited time on this world. Not being excited about new crap. When I buy something I choose wisely. I bought iPhone. I can buy latest iPhone x but I bought iPhone 7 cause it’s from fucking metal. And I know that metal is harder then glass, why the fucking apple forgot about it? I don’t know.
I know that I am clumsy and drop stuff. Dropped my phone at least 100 times and nothing.

I am not a apple fan boy I won’t buy mac with this glowing shit above keyboard that would got me blind at night.
I buy something when I know that it can save my time on this world. I try to buy things that make me productive and don’t break after a year.

So now piece of advise, stop wasting your time, buy and update wisely, wait a week or a month or a year when more people buy shit and buy what’s not broken. And if something’s broken rant this shit so next customer can be smarter.
Cheers

Maxi-Rant, rest in the first comment!

Yay, I've caught up with my "watch later" list on YouTube! Next thing: Just quickly go through my subscribed channels and add old videos that I haven't seen yet to the watch later list so that I have more stuff to watch the next months. The easiest way to do that is to go to the "all uploads" playlist of the channel (that is luckily always linked now, it used to be hidden sometimes) and use "add all to" to get them on my playlist. Then sort out the stuff that I've already seen and turn on automatic sorting by date, easy. Yeah...
Firstly, in the new design there's no "add all to", I have to go to the old design. For my own playlists, there's a handy "edit" button to do that, but on other pages I have to do it manually. Luckily I have set Ctrl+Shift+1 as a shortcut for "&disable_polymer=true" long ago.
Next surprise: On "all uploads" playlists, there is no "add all to" button. It's on every single other playlist on YouTube, including "liked", "watch later", "favourites" and so on, just not there.
Fine, I'll just abuse my subscription playlist script that I already have by making a copy of it, putting the channel IDs in it and setting the last execution date to 1.1.2001. Little problem with that: Google apps scripts can run for at most 5 minutes and the YouTube API restricts it to add one video per second. So it doesn't work for more than 300 videos. I could now try to split it up by dates, but I didn't write the script myself and I don't know how it sorts the videos to add, so I'll just google for another solution instead.
Found one: Go to the video overview of the channel in the old layout, Ctrl+Shift+I, paste this little Javascript thing and it automatically clicks all the little clocks that add the video to the watch later list. Yay, that works! Ok, i'm restricted to 5000 videos, because that's the maximum size of a YouTube playlist, so I can't immediately add all 8000+, but whatever, that's a minor problem and I'll sort out later anyway. Still another little problem: For some reason I can't automatically sort the watch later list. Because that would be too easy.
But whatever, I'll just use "add all to" from there to add it to my creatively named "WL" list. If that thing is restricted by the same rate limit of 1 video per second, it should be done in about 1½ hours. A bit long, but hey, I'm dealing with 5000 videos. Waiting 2 hours... Waiting 3 hours... Nothing happens. It would be nice if it at least added them one by one, but no, it waits an eternity and then adds all at once. At least in theory, right now it does absolutely nothing.
Shortly considered running it for more hours or even days on my Raspberry Pi, but that thing already struggles when using Chromium normally, I shouldn't bother it with anything that has to do with 5000 videos.
Ok, what else can I do then? Googling, trying out different things, mainly external services that have their own concept of "playlists" and can then add them to an arbitrary playlist later...
Even tried writing my own Java program with the YouTube API, but after about an hour not even the example program in the YouTube API tutorial worked (50 errors and even more open questions, woohoo), so I discarded that idea.
Then I discovered "DiskYT". Everything looked like it would work and I'm still convinced that I can do it with that little pile of shit. Why is it a pile of shit? Well, for example the site reloads itself after a while, so it can at most add 700 videos to a playlist. Also I can't just paste the channel link (even though it recognises those links, but just to show an error message that it can't copy from channels). I can't enter/paste URLs, I have to drag them. The site saves absolutely nothing (should in theory work, but in practise it doesn't), so I have to re-drag everything on every try. In one network, the "authorise YouTube" button (that I have to press again on every computer) does absolutely nothing ("inspect" reveals that there isn't even any action bound to the button), in another network the page mostly doesn't work at all or the button to copy from playlists is suddenly gone or other weird stuff. Luckily I have the WiFi at home, there it works in theory. But just on my desktop PC, no other device, wow. I tried to run it on my new laptop, but it's so new that it still has the preinstalled OS and there I can't deactivate going to standby when closing the laptop, so while I expected it to add 5000 videos, it instead added 4 and went to standby. But doesn't matter, because it would have failed at about 700 anyway. Every time I try to use this website, I get new problems, but it seems to still be the best option, because everything else just doesn't do anything. This page at least got to 700 before.

Continuing in first comment!

what the f....

So I'm making some changes to my setup. I'm relieving my current router from its duties and retiring it as a mini PC for my desktop setup. And I got my hands on a Dell Optiplex that will become my new router.

Now, firstly, the Optiplex came w/o a wifi antenna. I booted it up into a LinuxMint install USB for the first time and didn't expect much from it, but to my surprise, I got a popup: "There are wifi networks available". At that spot there was also my Fenvi PCI wifi card's antenna of my current (soon-to-be-previous) PC and it was barely seeing any wifi, and there came Optiplex with NO antenna attached to it and it managed to maintain stronger and more stable signal. wtf....

Alright, it's Fenvi, it's chinese -- there's probably not much I should expect from it.

Then I hooked it up right next to my current router with an external USB wifi adapter having 4x6dBi antennas on it, serving as my current wifi AP. Trying out hostapd configs, searching for the right channels,... should I test it? Naah, it still doesn't have an antenna - it won't reach my laptop. Meeh, for shits and giggles! `hostapd -d /etc/hostapd/hostapd_custom.conf`, on my lappy `nmcli d wifi rescan; sleep 5; nmcli d wifi` and... wtf... To my surprise, the AP was there! A thick wall away, no antenna whatsoever, and I still could connect to that Optiplex AP and post this rant!

What magic is this??? I'm now a bit concerned about ordering an antenna for it - I'm worried it could either worsen the signal or make it so strong that it'll fry my brains overnight.

Question about conditioning my new android lithium battery.

I dont understand what's happening with my phone. Have old Xperia Z3 D6603 (running android 6.0 marshmallow).

Had problems with battery since it was not lasting even 5 minutes so bought a new battery from ebay and installed it yesterday.

So first time I put it to my phone it showed that it had 70% of charge. I've read in battery description that I have to discharge the battery and recharge 3 times.

First time I wanted to discharge from 70% to 1% and with a battery discharge app + youtube 1080p videos + wifi signal it took only around 1 hour and phone was at 1%. From 1% till complete discharge it took me extra hour and then phone died.

I plugged it to charge and after 15 minutes it showed that battery now is at 100% (which is insane, it should take 2-3hrs to charge it up to 100%). So I charget it for 2-3 hrs ignoring that it said 100% already.

I discharget it from 100% to 1% in 1 hour and now again phone is stuck at 1% and it took me 2 more hours to discharge phone until battery died completely.

I don't believe that this behaviour will fix itself. How can I fix this problem so that battery percentage would be distributed evenly? Now it drops from 100% to 1% in 1hr and then from 1% to 0% in 2 hrs.
