rant? rant!

I work for a company that develops a variety of software solutions for companies of varying sizes. The company has three people in charge, and small teams that each worked on a certain project. 9 months ago I joined the company as a junior developer, and coincidentally, we also started working on our biggest project so far - an online platform for buying groceries from a variety of vendors/merchants and having them be delivered to your doorstep on the same day (hadn't been done to this scale in Estonia yet). One of the people from management joined the team working on that. The company that ordered this is coincidentally being run by one of the richest men in Estonia. The platform included both the actual website for customers to use, a logistics system for routing between the merchants, the warehouse, and the customers, as well as a bunch of mobile apps for the couriers, warehouse personnel, etc. It was built on Node.js with Hapi (for the backend stuff), Angular 2 (for all the UIs, including the apps which are run through a WebView wrapper), and PostgreSQL (for the database). The deadline for the MVP we (read: the management) gave them, but we finished it in about 7 months in a team of five.

The hours were insane, from 10 AM to 10 PM if lucky. When we weren't lucky (which was half of the time, if not more), we had to work until anywhere from 12 PM to 3 AM, sometimes even the whole night. The weekends weren't any better, for the majority of the time we had to put in even more extra hours on the weekends. Luckily, we were paid extra for them, but the salary was no way near fair (the majority of the team earned about 1000€/mo after taxes in a country where junior developers usually earn 1500€/month). Also because of the short deadline given to us, we skipped all the important parts like writing tests, doing CI, code reviews, feature branching/PR's, etc. I tried pushing the team and the management to at least write tests and make feature branches/PRs, but the management always told me that there wasn't enough time to coordinate and work on all that, that we'll do that after launching the MVP, etc. We basically just wrote features, tested them by hand, and pushed into the "test" branch which would later get tested and merged into master.

During development, one of the other juniors managed to write the worst kind of Angular code you could imagine - enormous amounts of duplication, no reusable components (every view contained the everything used in the view, so popups and other parts that should logically be reusable were in every view separately), fuck - even the HTML was broken (the most memorable for me were the "table > tr > div > td" ones, but that's barely scratching the surface). He left a few months into the project, and we had to build upon his shit, ever so slightly trying to fix the shit he produced. This could have definitely been avoided if we did code reviews.

A month after launching the MVP for internal testing, the guy working on the logistics system had burned out and left the company (he's earning more than twice the salary he got here, happy for him, he is a great coder and an even better team player). This could have been avoided if this project had been planned better, but I can't really blame them, since it was the first project they had at this scale (even though they had given longer deadlines for projects way smaller than this).

After we finished and launched the MVP, the second guy from management joined, because he saw we needed extra help. Again I tried to push us into investing the time to write tests for the system (because at this point we had created an unstable cluster fuck of a codebase), but again to no avail. The same "no time, just test it manually for now, we'll do that later when we have time" bullshit from management.

Now, a few weeks ago, the third guy from management joined. He saw what a disaster our whole project was. Him joining was simply a blessing from the skies. He started off by writing migrations using sequelize. I talked to him about writing tests and everything, and he actually listened. He told me that I'm gonna be the one writing them, and also talked to the rest of management about it. I was overjoyed. I could actually hear the bitterness in the voices of the rest of management when they told me how to write the tests, what to test, etc. But I didn't give a flying rat's ass, I was hapi.

I was told to start off by writing a smoke test for the whole client flow using Puppeteer. I got even happier, since I was finally able to again learn new things (this stopped at about 4 or 5 months into the project).

I'm using jest as the framework and started writing the tests in TypeScript. Later I found a library called jest-extended, but it didn't have type defs, so I decided to write them and, for the first time in my life, contribute to the open source community.

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.
