Long rant ahead, but it's worth it.

I used to work with a professor (let's call him Dr. X) and developed a backend + acted as sysadmin for our team's research project. Two semesters ago, they wanted to revamp the front end + do some data visualization, so a girl (let's call her W) joined the team and did all that. We wanted to merge the two sites and host on azure, but due to issues and impeding conferences that require our data to be online, we kept postponing. I graduate this semester and haven't worked with the team for a while, so they have a new guy in charge of the azure server (let's call him H), and yesterday my professor sends me (let's call me M), H and W an email telling us to coordinate to have the merge up on azure in 2-3 days, max. The following convo was what I had with H:

M: Hi, if you just give me access to azure I'll be able to set everything up myself, also I'll need a db set up, and just send me the connection string.
H: Hi, we won't have dbs because that is extra costs involved since we don't have dynamic content. Also I can't give you access, instead push everything on git and set up the site on a test azure server and I will take it from there.
M: There is proprietary data on the site...
H: Oh really? I don't know what's on it.
<and yet he knows we have no dynamic data>
M: Fine, I'll load the data some other way, but I have access to all the data anyway, just talk to Dr. X and you'll see you can give me access. Delete my access after if you want.
H: No, just do what I said: git then upload to test azure account.

Fine, he's a complete tool, but I like Dr. X, so I message W and tell her we have to merge, she tells me that it's not that easy to set it up on github as she's using wordpress. She sends me instructions on what to do, and, lo and behold, there's a db in her solution. Ok, I go back to talking to H:

M: W is using a db. Talk to her so we can figure out whether we need a database or not.
H: We can't use a database because we want to decrease costs.
M: Yes I know that, so talk to her because that probably means she has to re-do some stuff, which might take some time. Also there might be dynamic content in what she's doing.
H: This is your project, you talk to her.
<I'm starting to get mad right now>
M: I don't know what they had her do apart from how it interfaces with what I've done.
H: We still can't have databases.
M: Listen, I don't do wordpress, and I'm not gonna mess with it, you talk to her
H: I won't do any development
<So you won't do any dev, but you won't give me access to do it either?>
M: Man, the bottleneck isn't the merging right now, it's the fact that W needs a db
H: I know, so talk to her
M: THE RESTRICTION TO NOT HAVE DATABASES IS NOT MINE, IT'S YOURS, YOU TALK TO HER. I can't evaluate whether it's a reasonable enough reason or not since I don't know the requirements or what they're willing to spend.
H: It's your project.
M: Then give me fucking access to azure and I'll handle it, you know you'll have to set up wordpress again regardless whether we set it up the first time.
H: Man just do your job.

At this point I lost it. WHAT A FUCKING TOOL. He doesn't wanna do dev work, wants me to go through the trouble of setting up on a test subscription first, and doesn't want to give me access to azure. What's more, he did shit all and doesn't want to anything else. Well fuck you. I googled him, to see if he's anyone important, if he's done anything notable which is why he's being so God damn condescending. MY INTERNSHIP ALONE ECLIPSES HIS ENTIRE CV. Then what the fuck?

There's also this that happened sometime during our talk:

M: You'll have to take to Dr. Y so he'll change the DNS to point to the azure subscription instead of my server.
H: Yea don't worry, too early for that.
M: DNS propagation takes 24 hours...
H: Yea don't worry.

DNS propagation allows the entire web to know that your website is hosted on a different server so it can change where it's pointing to. We have to do this in 2-3 days. Why do work in parallel? Nah let's wait.

I went over his head and talked to the professor directly, and despite wanting to tell him that he was both drunk and high the day he hired that guy, I kept it professional. He hasn't replied yet, but this fucker's pompous attitude is just too much for me alone, so I had to share.

PS: I named his contact as Annoying Prick 4 minutes into our chat. Gonna rename him cz that seems tooooooo soft a name right now.

Scene: Senior developer left, 3 Junior devs(including me) are now loaded with work.

*Intern asks for help*

JuniorDev1: I have 2 projects of which i'm the lead on one. I don't have time to help anyone.
JD2: 2 projects as well dude, speak to me after work, much easier then.
Me: 3 projects, lead on two. Sure how can i help you.

Took less than 5 minutes to help the intern.

2 hours Later. Check in meeting

PM: Our Junior devs are really busy and can't always help you guys. JD1 are you overloaded?

JD1: Yes, is their anyway we can split the one projects work?

PM: Sure. JD2 are you overloaded?

JD2: Not really, but i agree on splitting the projects between the three of us.

Me: *Are these fuckers serious? i have three projects, they have 2 and they wanna give me more work because they are overloaded and don't know how to manage their time*

PM: Ok cool, i'll update it. CooCooK4Choo, i see you building your own game during lunch time. You definitely not overloaded.

Me: Actually! what i do in my lunch time is my own personal work because it's the only time i have to work on personal projects. I actually do feel overloaded with the 3 projects and now more work from them, could we split the work load evenly please.

PM: I thought you said you could handle the 3 projects?

Me: I can, i have been, but with more work coming my way i don't think i'll be able to.

PM: Unfortunately i need the other Junior Devs on demand, so i won't be able to split the work load evenly.

Me: On demand for what? Why not let the interns help?

PM: In case i need their help. The interns are helping the other Junior Devs with things that don't require too much out of them.

Me: *This FUCKEN BITCH!* Cool, I'm done with the 1 project, expect the business rules at the end of the day. I'll see if i can get the other 2 near done by Friday so i can have time to look over the code of the new projects that i'll be splitting with the other Junior Devs.

PM: Cool, glad we all on the same page.

You know what? FUCK this stupid shit of favoring people in the FUCKEN work place.
This is my first full-time job ever, I've been here for a full year today and i can honestly say these people are just giant children with money. I should know, out of work i am a giant child, but from 8:00 - 16:00 i'm a FUCKEN adult.

TL;DR: check polarity before plugging your DIY circuits into others!!!

*goes off to watch some Lucky Star and drink some booze*
*notices phone battery dying after 3rd pint*

But my charging cable that Huawei delivered with this thing is way too short... Well that ain't no problem, I can make one of my own 😎

But I'm tipsy.. sound I really enter the workbench in this state?

*goes off to build a charging cable anyway*
But what was USB-A male connector's polarity again? Oh, there's the fan's USB connector that I've made in the past. Let's check on that one. So, left is positive and right is negative?

*solders the wires on*
Snip, strip, stick, done! Well that was easy. I guess that all those failed soldering attempts and lost pads in the past as a means of training did pay off in the end!

*plugs phone into Raspberry Pi media center through new charging cable*

Strange sounds coming from the speakers.. well that's odd. Reverse polarity or maybe the Pi can't handle a 1A load from my phone?

*plugs phone into the 5V 5A charging hub that I've made earlier*
That oughta do.. current limits should be no more in that thing.

*charging hub makes high-pitch noise similar to the Pi speakers*
Definitely a reverse polarity, isn't it :') let's check on the Gargler...
Oh shit! It is a reverse polarity mistake!!! Should've checked this earlier >_<

*resolders wires properly*
Alright, finally done.. as I'm writing this post, my phone's charging from the Raspberry Pi through my fixed charging cable now...

Lesson learned. Always check on the internet what the pinout is before soldering anything, don't solder while tipsy, and be fucking grateful that this phone has reverse polarity protection in it.

Nexus 6P with all its shortcomings regarding power delivery and battery management, luckily it's got reverse voltage protection features built-in. Otherwise it might've costed me my phone. Always double-check before plugging anything into something else!!!

I've optimised so many things in my time I can't remember most of them.

Most recently, something had to be the equivalent off `"literal" LIKE column` with a million rows to compare. It would take around a second average each literal to lookup for a service that needs to be high load and low latency. This isn't an easy case to optimise, many people would consider it impossible.

It took my a couple of hours to reverse engineer the data and implement a few hundred line implementation that would look it up in 1ms average with the worst possible case being very rare and not too distant from this.

In another case there was a lookup of arbitrary time spans that most people would not bother to cache because the input parameters are too short lived and variable to make a difference. I replaced the 50000+ line application acting as a middle man between the application and database with 500 lines of code that did the look up faster and was able to implement a reasonable caching strategy. This dropped resource consumption by a minimum of factor of ten at least. Misses were cheaper and it was able to cache most cases. It also involved modifying the client library in C to stop it unnecessarily wrapping primitives in objects to the high level language which was causing it to consume excessive amounts of memory when processing huge data streams.

Another system would download a huge data set for every point of sale constantly, then parse and apply it. It had to reflect changes quickly but would download the whole dataset each time containing hundreds of thousands of rows. I whipped up a system so that a single server (barring redundancy) would download it in a loop, parse it using C which was much faster than the traditional interpreted language, then use a custom data differential format, TCP data streaming protocol, binary serialisation and LZMA compression to pipe it down to points of sale. This protocol also used versioning for catchup and differential combination for additional reduction in size. It went from being 30 seconds to a few minutes behind to using able to keep up to with in a second of changes. It was also using so much bandwidth that it would reach the limit on ADSL connections then get throttled. I looked at the traffic stats after and it dropped from dozens of terabytes a month to around a gigabyte or so a month for several hundred machines. The drop in the graphs you'd think all the machines had been turned off as that's what it looked like. It could now happily run over GPRS or 56K.

I was working on a project with a lot of data and noticed these huge tables and horrible queries. The tables were all the results of queries. Someone wrote terrible SQL then to optimise it ran it in the background with all possible variable values then store the results of joins and aggregates into new tables. On top of those tables they wrote more SQL. I wrote some new queries and query generation that wiped out thousands of lines of code immediately and operated on the original tables taking things down from 30GB and rapidly climbing to a couple GB.

Another time a piece of mathematics had to generate all possible permutations and the existing solution was factorial. I worked out how to optimise it to run n*n which believe it or not made the world of difference. Went from hardly handling anything to handling anything thrown at it. It was nice trying to get people to "freeze the system now".

I build my own frontend systems (admittedly rushed) that do what angular/react/vue aim for but with higher (maximum) performance including an in memory data base to back the UI that had layered event driven indexes and could handle referential integrity (overlay on the database only revealing items with valid integrity) or reordering and reposition events very rapidly using a custom AVL tree. You could layer indexes over it (data inheritance) that could be partial and dynamic.

So many times have I optimised things on automatic just cleaning up code normally. Hundreds, thousands of optimisations. It's what makes my clock tick.

At an expensive Apache Spark training class. For hands on portion you use their system. When everyone logged on, their system couldn't handle the load. First they blamed the hotel wifi (even though every other site was running perfectly) and then they blamed AWS. It's clearly an issue with their system. It's ridiculous to not be honest with a room full of developers who know what's up.

Best code performance incr. I made?

Many, many years ago our scaling strategy was to throw hardware at performance problems. Hardware consisted of dedicated web server and backing SQL server box, so each site instance had two servers (and data replication processes in place)

Two servers turned into 4, 4 to 8, 8 to around 16 (don't remember exactly what we ended up with). With Window's server and SQL Server licenses getting into the hundreds of thousands of dollars, the 'powers-that-be' were becoming very concerned with our IT budget. With our IT-VP and other web mgrs being hardware-centric, they simply shrugged and told the company that's just the way it is.

Taking it upon myself, started looking into utilizing web services, caching data (Microsoft's Velocity at the time), and a service that returned product data, the bottleneck for most of the performance issues. Description, price, simple stuff. Testing the scaling with our dev environment, single web server and single backing sql server, the service was able to handle 10x the traffic with much better performance.

Since the majority of the IT mgmt were hardware centric, they blew off the results saying my tests were contrived and my solution wouldn't work in 'the real world'. Not 100% wrong, I had no idea what would happen when real traffic would hit the site.

With our other hardware guys concerned the web hardware budget was tearing into everything else, they helped convince the 'powers-that-be' to give my idea a shot.

Fast forward a couple of months (lots of web code changes), early one morning we started slowly turning on the new framework (3 load balanced web service servers, 3 web servers, one sql server). 5 minutes...no issues, 10 minutes...no issues,an hour...everything is looking great. Then (A is a network admin)...
A: "Umm...guys...hardly any of the other web servers are being hit. The new servers are handling almost 100% of the traffic."
VP: "That can't be right. Something must be wrong with the load balancers. Rollback!"
A:"No, everything is fine. Load balancer is working and the performance spikes are coming from the old servers, not the new ones. Wow!, this is awesome!"
<Web manager 'Stacey'>
Stacey: "We probably still need to rollback. We'll need to do a full analysis to why the performance improved and apply it the current hardware setup."
A: "Page load times are now under 100 milliseconds from almost 3 seconds. Lets not rollback and see what happens."
Stacey:"I don't know, customers aren't used to such fast load times. They'll think something is wrong and go to a competitor. Rollback."
VP: "Agreed. We don't why this so fast. We'll need to replicate what is going on to the current architecture. Good try guys."
<later that day>
VP: "We've received hundreds of emails complementing us on the web site performance this morning and upset that the site suddenly slowed down again. CEO got wind of these emails and instructed us to move forward with the new framework."

After full implementation, we were able to scale back to only a few web servers and a single sql server, saving an initial $300,000 and a potential future savings of over $500,000. Budget analysis considering other factors, over the next 7 years, this would save the company over a million dollars.

At the semi-annual company wide meeting, our VP made a speech.

VP: "I'd like to thank everyone for this hard fought journey to get our web site up to industry standards for the benefit of our customers and stakeholders. Most of all, I'd like to thank Stacey for all her effort in designing and implementation of the scaling solution. Great job Stacy!"
<hands her a blank white envelope, hmmm...wonder what was in it?>

A few devs who sat in front of me turn around, network guys to the right, all look at me with puzzled looks with one mouth-ing "WTF?"

After 3 years of being the first in and last to leave, of getting other people's work reassigned to me - P can't complete it on time, G doesn't like the user, A refuses to work on that module, etc... I finally blew last Sept.
In the span of 2 days, my boss brought me into a project 1.5 years in (she doesn't trust P to do the coding) and expected me to be up to speed and coding in a couple of days, told the functional dept that I would cover for one of their guys on vaca for three weeks and assigned me to take over a HUGE project from one of the other functional guys who wasn't getting it done. So basically I'm now doing Ps job AND supporting another department AND taking control of a large project from another department. I'm the idiot working 14 hour days while they're all leaving on time or enjoying their 3 week vaca to India.
I lost it. It's bad enough filling in the gaps in my own department but when I'm now taking on work for other departments, that's where I draw the line. I sent my boss my resignation - just could not take the inequity in the work load.
I'm still working here - my boss ended up hiring a consultant to handle the functional project and told the functional group to find their own vacation coverage. She's also monitoring workloads much closer now. I still habe an ongoing issue with having to complete other peoples work for them but I'm not working OT to do it. So speaking up helps. So does quitting.

I once agreed to maintain and develop an application used in a different section of the school to keep inventory and make sure everything is where it is supposed to be.

At first there was enthusiasm, together with 2 of my classmates we agreed and git clone-d the .NET application that now graduated students built and maintained for the past few years. What could go wrong right?!

It became clear that the original students that worked on it followed an older curriculum, meaning they still got taught .NET instead of the core variant that we get now, not only that but it also seemed that they either did not fully grasp the Clean/Onion architecture or didn't get it in class since there were infrastructure components in the 'Domain' project of the solution. Think of 2 DBContexts in the domain model, yep.

One of us bailed in the first week, the other one and I felt bad for the people using the app so we went on and tried to work on the first bugs that were described in a document. One of these bugs was 'whenever I filter on something in the list, everybody gets to see that filter on their screen instead of only me'. Woah that's weird! Let's see how they put that together!

Oh god, they are using a _static_ variable to store filters, no wonder that it doesn't work properly. Ever heard of sessions?!

Second bug: Sometimes people can't create an account when we sign them up from the admin panel. Alright that is weird, let's figure that one out! Wait a second it seems to work in development? What's this about.

Oh wait I can't create an account on production either? Oh that's weird, wait a second... Why do I have to put my e-mail in a form that was sent to me through e-mail? Why is my address not filled in already? OOH, if someone types in the wrong e-mail address (which is easy since our school has 4 variants of the same f*cking e-mail address) it won't work since it can't recognize the user! Brilliant! Remove e-mail input box and make a token/queryparam determine the user account.

Ah that seems good, it's a mess but it seems a tiny bit better now, great! We're making progress and some sweet buck.

Next bug, trillions of 50x errors on random pages, that's a weird one.

Hm everything works in development, that's odd. Is the production data corrupted?

DID I MENTION that in order to get into the system in development we have to load in a f*cking production database backup ON OUR DEVELOPMENT MACHINE and then ask one of the users' password to login to it and create an account for ourselves? Seeding? What's that, right?!

Anyway, back to bug fixing. I e-mail the the people responsible for the app and get a production admin account, oh I also can't ssh into it because of policies so I have to do everything over e-mail and figure out what's causing the errors. I somehow also wonder if they have any kind of virtualization in place, giving students a VM to do that stuff in doesn't seem so weird does it ? Even with school policies?

Oh btw, 'deploying' means sending a .zip file to a guy in another building and telling him how to configure it, apparently this resulted in a missing folder that the application needed to work and couldn't make on its own. This after 2 weeks of e-mailing back and forth.

After 3 months i quit out of despair and sadness, and due to the fact that I just couldn't do it anymore. I separated everything into logical subprojects and let the last guy handle it, he was OK with that and understood why I left.

Luckily, around that time I already had an actual job at a software development company :)

Man, contributing to open source projects seems very intimidating to me.

I have never contributed to one of those repos on Github with a shit-ton of stars and a load of watchers. Made up my mind to start sometime around the start of September. Looked up a repo that I was very excited to contribute to. Went through their really large codebase, tried to understand as much as I could (They have a fair amount of documentation, but I just can't understand a lot of design decisions that were taken). Looked up one of the open issues marked for newbies, went through the relevant code to understand where and how I would have to make my changes in the code, and was about to start... when a seasoned contributor submitted a pull request.

This same occurrence has repeated itself 3 times now. If you mark an issue for beginners, maybe let the beginners handle them? Also, if you plan to contribute to an issue, why not announce your intention to do so? Get the issue assigned to you, so no one else ends up wasting their time coming up with a solution.

I would love to recommend this to the contributing team, but I am just way too scared to initiate a conversation with these guys. I mean, they are way more experienced and knowledgeable than me (some of them are even famous!).

I am definitely out of my depth with this project, and maybe should look for an easier one, but I really want to rise up to the challenge. Guess I'll stick around then, just waiting for my chance. :|

I am currently looking for a DAW (Digital Audio Workstation), because my music projects are starting to get a little too complex for Audacity.

So I started looking for a good, easy-to-learn, ideally free program, and quickly learned that Avid now has a free version of Pro Tools called First.

So I go to their site and fill out the registration form to get the download. In addition to creating an account with Avid, you also need to create one with iLok, which apparently has something to do with how they manage their licenses. Kinda overkill for a free program, but okay...

I download the program (about 3gigs...), install it and try to start it. It gives me an error message about missing some service. Okay? I'm confused because I notice that an 'Application Manager' service has appeared in my tray, and when I open that I can log into my new account just fine. But it still doesn't work.

There's a link in the error message to the iLok website, and it looks like ai need to dowload and install another component. Why didn't that get installed with the program if it's required?

Hmm...

So I go to the iLok site, download it and install it. Pro Tools First still won't start. I realize that the PTF installer asked me to reboot, which I didn't do because: a) I always have a lot of windows open, and b) How often is a reboot ACTUALLY required? Why would you need to reboot?

So I (begrudgingly) reboot, and now the program seems to start initializing... but then it throws an error message about some plugin that it can't load because it doesn't work for the 64 bit version. Then... why are you even looking for it?
And then it says something like: 'I can't handle that, I'm just gonna shut down'.

What?

I try starting it again. Same error appears, but then it gets past it this time... Only to throw another error message about something else it can't load, and therefore it must shut down.

Deep breath.

Third time is the charm, the program actually made it to the project create/load screen! Huzzah!
So I look around a bit, but don't do much. It doesn't seem too intuitive to me, so I start watching some tutorials on YouTube from Avid themselves. It's a little late by now, so I don't get my hands dirty that day.

Next time I want to try out the program I start it up, still get error messages, but it does seem to initialize okay. But then the 'Create project' button doesn't react when I press it.

It turns out that the program takes a looong time to log in to the avid account, even though the manager service is running and logged in...

When it finally logs on I create a new blank project, but it doesn't ask me where to save it to. I see there is a counter saying 1/3 and looking around I find some info about 'cloud based projects'.

It would seem that this program only supports saving projects to the cloud, and you get only 3 projects total. Three. THREE?

Ahem...

I add an instrument track to my new project and select the one and only plugin, which is a synth. I don't see the plugin window, like in the tutorials I watched. I fiddle around with the windows, but I only manage to get the layout fucked up. There's a handy 'Window' menu, but none of the options resets the view. The main window is now sporting a WINDOWS FUCKING 7 BORDER! And partially blocking the view of the top menu.

Blaaargh!

Frustrated, I shut the program down and restart it. I now select one of the project templates (after waiting for it to LOG IN AGAIN!) in the hope that I might have a bit more luck with that starting point.

But when the template has loaded, out of nowhere, the program goes from maximized to windowed mode! And the fucking Win7 border is back again, still messing with the main menu!

FFS!

I get the sucker maximized again and select one of the synth tracks, and Lo and Behold! The synth plugin window actually shows up! But of course there is no sound produced when I play, neither with the keyboard or my midi keyboard.

Oh no, that would have been too easy.

I see some the meters moving when I play, but no sound is produced. I check the options menu, but find out nothing useful except for the fact that the program only support 48kHz sample rate. That's pretty disappointing when you have a 192kHz/24bit soundcard.

I'm done. This piece of shit software is NOT for me. It's bloated, complicated to sign up for and install, extremely limited and buggy as hell!

The final insult is that it takes 5 minutes to uninstall because there is no uninstall option in the so-called 'Application Manager' (of course fucking not!), and doing it through Programs & Features there are 5 (FIVE!!) different apps and services to uninstall, one by one.

0/10, would not recommend.

WHAT

and that was the story all about how my life got flipped turned upside down

what fucking system has a coprocessor after 2002? (My laptop is a 2008 HP something or other)

Of course the shouting episodes all happened during the era I was doing WordPress dev.

So we were a team of consultants working on this elephant-traffic website. There were a couple of systems for managing content on a more modular level, the "best" being one dubbed MF, a spaghettified monstrosity that the 2 people who joined before me had developed.

We were about to launch that shit into production, so I was watching their AWS account, being the only dev who had operational experience (and not afraid to wipe out that macos piece of shit and dev on a real os).

Anyhow, we enable the thing, and the average number of queries per page load instantly jumps from ~30 (even vanilla WP is horrible) to 1000+. Instances are overloaded and the ASG group goes up from 4 to 22. That just moves the problem elsewhere as now the database server is overwhelmed.

Me: we have to enable database caching for this thing *NOW*

Shitty authors of the monstrosity (SAM): no, our code cannot be responsible for that, it's the platform that can't handle the transition.

Me: we literally flipped a single switch here and look at the jump in all these graphs.

SAM: nono, it's fine, just add more instances

Me: ARE YOU FUCKIN SERIOUS?
Me: - goes and enables database caching without any approvals to do so, explaining to mgmt. that failure to do so would impair business revenue due to huge loading times, so they have to live with some data staleness -

SAM: Noooo, we'll show you it's not our code.
SAM: - pushes a new release of the monstrosity that makes DB queries go above 2k / page load -

...

Tho on the bright side, from that point on I focused exclusively on performance, was building a nice fragment caching framework which made the site fly regardless of what shitty code was powering it, tuned the stack to no end and learned a ton of stuff in the process which allowed me to graduate from the tar pit of WP development.

I need some opinions on Rx and MVVM. Its being done in iOS, but I think its fairly general programming question.

The small team I joined is using Rx (I've never used it before) and I'm trying to learn and catch up to them. Looking at the code, I think there are thousands of lines of over-engineered code that could be done so much simpler. From a non Rx point of view, I think we are following some bad practises, from an Rx point of view the guys are saying this is what Rx needs to be. I'm trying to discuss this with them, but they are shooting me down saying I just don't know enough about Rx. Maybe thats true, maybe I just don't get it, but they aren't exactly explaining it, just telling me i'm wrong and they are right. I need another set of eyes on this to see if it is just me.

One of the main points is that there are many places where network errors shouldn't complete the observable (i.e. can't call onError), I understand this concept. I read a response from the RxSwift maintainers that said the way to handle this was to wrap your response type in a class with a generic type (e.g. Result<T>) that contained a property to denote a success or error and maybe an error message. This way errors (such as incorrect password) won't cause it to complete, everything goes through onNext and users can retry / go again, makes sense.

The guys are saying that this breaks Rx principals and MVVM. Instead we need separate observables for every type of response. So we have viewModels that contain:

- isSuccessObservable
- isErrorObservable
- isLoadingObservable
- isRefreshingObservable
- etc. (some have close to 10 different observables)

To me this is overkill to have so many streams all frequently only ever delivering 1 or none messages. I would have aimed for 1 observable, that returns an object holding properties for each of these things, and sending several messages. Is that not what streams are suppose to do? Then the local code can use filters as part of the subscriptions. The major benefit of having 1 is that it becomes easier to make it generic and abstract away, which brings us to point 2.

Currently, due to each viewModel having different numbers of observables and methods of different names (but effectively doing the same thing) the guys create a new custom protocol (equivalent of a java interface) for each viewModel with its N observables. The viewModel creates local variables of PublishSubject, BehavorSubject, Driver etc. Then it implements the procotol / interface and casts all the local's back as observables. e.g.

protocol CarViewModelType {
isSuccessObservable: Observable<Car>
isErrorObservable: Observable<String>
isLoadingObservable: Observable<Void>
}

class CarViewModel {
isSuccessSubject: PublishSubject<Car>
isErrorSubject: PublishSubject<String>
isLoadingSubject: PublishSubject<Void>

// other stuff
}

extension CarViewModel: CarViewModelType {
isSuccessObservable {
return isSuccessSubject.asObservable()
}
isErrorObservable {
return isSuccessSubject.asObservable()
}
isLoadingObservable {
return isSuccessSubject.asObservable()
}
}

This has to be created by hand, for every viewModel, of which there is one for every screen and there is 40+ screens. This same structure is copy / pasted into every viewModel. As mentioned above I would like to make this all generic. Have a generic protocol for all viewModels to define 1 Observable, 1 local variable of generic type and handle the cast back automatically. The method to trigger all the business logic could also have its name standardised ("load", "fetch", "processData" etc.). Maybe we could also figure out a few other bits too. This would remove a lot of code, as well as making the code more readable (less messy), and make unit testing much easier. While it could never do everything automatically we could test the basic responses of each viewModel and have at least some testing done by default and not have everything be very boilerplate-y and copy / paste nature.

The guys think that subscribing to isSuccess and / or isError is perfect Rx + MVVM. But for some reason subscribing to status.filter(success) or status.filter(!success) is a sin of unimaginable proportions. Also the idea of multiple buttons and events all "reacting" to the same method named e.g. "load", is bad Rx (why if they all need to do the same thing?)

My thoughts on this are:

- To me its indentical in meaning and architecture, one way is just significantly less code.
- Lets say I agree its not textbook, is it not worth bending the rules to reduce code.
- We are already breaking the rules of MVVM to introduce coordinators (which I hate, as they are adding even more unnecessary code), so why is breaking it to reduce code such a no no.

Any thoughts on the above? Am I way off the mark or is this classic Rx?

## 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?

Corona shows that certain webshops were bought up cheaply and can't handle large loads. The fact that my shopping cart constantly crashes, the website itself crashes, flips between logged in and logged out, state is constantly corrupted and.. every so now and then I get 500 server errors, yeah, clear signs of no load balancing policy.

Everyone is raping the shopping sites right now.

I hate cheapskates.

Can somebody explain to me why developers (especially web) have to micromanage every single thing into it's own f*ing component.

Story time: I have an input form with some tabs. I discovered that the UI Library (Devextreme) has a nice little component that handles forms, (including tabs, groups, etc.). So I make a page, configure tabs, inputs and whatnot.

Now, I already knew that my coworkers can't handle html that is bigger than a page. So instead of putting the configs in the frontend, I made nice files where I store those, to keep them nicely clean and seperated.

Me feeling very good, went off to have a nice lunch break.

I come back read the message from my coworker, asking me to make every tab it's own component and form and load them into a separate Tab-Component, instead of using the built in configuration

......

WHAT?

Like seriously. I have a f*ing library that handles that, why the f*ck do I need to reinvent the wheel here!?

Supposedly it's to make it more maintainable, easier to find bugs, flatten the hierarchy.

Here's a little wake up call you morons: Nesting hundreds of components into each other does *not* help you with that.
It just creates a rabbit-hole of confusing containers that you have to navigate and dissect every time you try to find something.

"Can I fix the bug in the detail Page? Sure I'll tell you tomorrow when I find out which fucking component the bug results from".

Components are there to be *reused*. It's using inheritance for reusing code all over again, but worse.

But maybe I'm just old fashioned, and conservative. Maybe I'm just a really bad software engineer, because nowadays everything seems to result in architectures spreading hundreds of folders, thousands of files with nothing but arbitrary cut-offs with no real benefit, that I don't see the value in.

I need help.
I don't know if I can do this anymore.

As much as I love coding, what I do and making new things, I feel like I can't handle it as well as I used to be able to. I was diagnosed with treatment-resistant depression and anxiety (amongst other things) and it's taking a toll on me. I can't work on problems as well as I used to. I overlooks simple errors and typos and spend hours trying to fix it. I can't focus on anything or even remember what I was doing a minute ago. I seem to constantly miss deadlnes. My performance has taken a nose-dive and I'm in constant fear of losing my job. I'm the breadwinner for my household (dad doesn't work, mom doesn't make enough) and much of my salary goes towards my family and rent.

I have a couple of attempts, and one of my recent ones got me fired from my previous job. I've tried to get help. I've gone to therapy, I'm on a shit-load of anti-depressants and trying to change the outlook of my life, but nothing seems t work.

I don' know what to do. I needed to vent out. What do you think I should do?
