When someone at work says your Java multi threaded code is too advanced for other people to understand so you have to dumb it down. What part of constant learning in software they don't understand?

Interviewer : So what frameworks and library you usually use?
Me : i use volley for networking, gson for parsing, livedata/architecture components for architecture and observability , room for database and java for app development

I : ok so make this sample app using retrofit for networking, moshi for parsing, mvrx for architecture , rx for observability , sqldelight for db, dagger2 and kotlin for app dev. You have 8 hours

Me :(wtf?) But i never used those libs or language!
I : we just want to check how easily you adapt to different surroundings.

Me : -_-

Honestly i don't know of it was a great experience or a bad one . I was stressed the whole time but was able to adapt to almost all of those libraries and frameworks.
At the end i got selected but decided not to go for those ppl. That was just a lucrative opening of a venus fly trap, they would have stressed the hell out of me

New AMD Rx 580x dual fan cooler

Hello World!

Migrating to my first Thinkpad (E585), something that I've wanted to do for a long time. I've heard a lot of great things and I wanted that sweeeet performance boost over my budget craptop (partially pictured).

> Ryzen 5 2500U
> RX Vega 8 integrated
> 8GB DDR4
> 256GB NVMe
> It's a thinkpad
> Runs Gentoo Linux and I swear I've spent the entire weekend learning and configuring it (my first time)

The office PCs are finally done 😌 Real beauties I think! 😊
Built 3 of them today with each the same parts:
- Ryzen 7 2700X
- Asus B450 Plus
- 16GB G.SKILL TridentZ RGB RAM
- M.2 Samsung 970 500GB SSD
- RX 570 8GB Armor Edition
- Bequiet CM 600W PSU
- NZXT H500 Case
- Riing 12 coolers

Theres a debate in my company about whether or not to be using RxSwift on iOS apps. I'm not 100% convinced. Today we had two submissions for a coding challenge come in. One uses nearly all the same Rx modules this company does, one was vanilla Swift.

Just by chance noticed the vanilla app writer contributed ~5k lines of code to the challenge overall. Including libraries, the Rx one contributed ~45k.

That to me is just bat shit crazy. It would want to be the most amazing, time saving, bug reducing thing the world has ever seen to justify that volume of code.

Got a Radeon RX 570 to complete my light gaming and rendering setup. This is easily the most powerful GPU I have ever owned, super hyped to try out all my games on this now. Works great after it crashed under Linux a few times for god knows what reasons but hey, not disappointed at all so far.

All AMD setup here (Ryzen + Radeon), feels good to be back on AMD after a long Intel/Nvidia stint.

10 yrs of saving for this new build. Ryzen 5 2600, AMD RX 5500xt, 32GB DDR3-3000, all in a case built like a fucking tank. So many payouts coming in all at once... did my luck really flip?

You know what's rocket science? Serial ports.

Every freakin' datasheet states RX/TX but not from which side of the connector. Some look at it from the inside (RX for own receive), some from the outside (RX for receive of the counterpart). But never ever try to explain what is what, that would be too easy.

On literally any first attempt of connecting devices in my life it was wrong. And then you switch 'em and it's still wrong. Then you switch again, and it may work. Or you have to switch a few times more, you never know.

Those freaking bastard interfaces from hell.

I gave you a chance, Nvidia. It could have been a good thing, but no. You are still crap. About two years ago, my son's graphics card (an Nvidia) died, so I thought, I'll give him my nice Radeon card, and got myself a new card. For some reason, reason failed me, and I got a GTX 1070. It's been a nice enough card, and worked well. And then the last driver update happened. Fallout 4 started to CTD before it even booted to the main menu. Me, not thinking (again) thought it was a mod, so I uninstalled and deleted and reinstalled again, with all 120 mods. Nope. Still crashing. Then I noticed, as the game booted, the fans started to ramp up, and I could tell exactly when it would crash be the sound of fans. I was expecting the computer to taxi out the room. Rolled the driver update back to the last one that worked. Now I can log in again, and things are mostly stable. Still crashes, but not as bad, probably due to reloading the mods and missing something. When the RX 3080 hits the market, bye bye Nvidia. You haven't changed a bit over the years. We're through.

Finally sold my 1070!

Now to finally purchase my RX 580, I'm one shackle down! :-D

People talking about NVIDIA drivers on Linux and how bad those are. Pretty sure that if I had any recent GTX 1080 I'e be able to actually play Rocket League on any fucking Linux distro. AMD drivers are worse. How the fuck can I have my RX 480 work in 3D applications (read: Rocket League) on any other Linux distro than Ubuntu 16.04? The internet doesn't have a solution for me.

!rant

Need some opinions. Joined a new company recently (yippee!!!). Just getting to grips with everything at the minute. I'm working on mobile and I will be setting up a new team to take over a project from a remote team. Looking at their iOS and Android code and they are using RxSwift and RxJava in them.

Don't know a whole lot about the Android space yet, but on iOS I did look into Reactive Cocoa at one point, and really didn't like it. Does anyone here use Rx, or have an opinion about them, good or bad? I can learn them myself, i'm not looking for help with that, i'm more interested in opinions on the tools themselves.

My initial view (with a lack of experience in the area):

- I'm not a huge fan of frameworks like this that attempt to change the entire flow or structure of a language / platform. I like using third party libraries, but to me, its excessive to include something like this rather than just learning the in's / out's of the platform. I think the reactive approach has its use cases and i'm not knocking the it all together. I just feel like this is a little bit of forcing a square peg into a round hole. Swift wasn't designed to work like that and a big layer will need to be added in, in order to change it. I would want to see tremendous gains in order to justify it, and frankly I don't see it compared to other approaches.

- I do like the MVVM approach included with it, but i've easily managed to do similar with a handful of protocols that didn't require a new architecture and approach.

- Not sure if this is an RxSwift thing, or just how its implemented here. But all ViewControllers need to be created by using a coordinator first. This really bugs me because it means changing everything again. When I first opened this app, login was being skipped, trying to add it back in by selecting the default storyboard gave me "unwrapping a nil optional" errors, which took a little while to figure out what was going on. This, to me, again is changing too much in the platform that even the basic launching of a screen now needs to be changed. It will be confusing while trying to build a new team who may or may not know the tech.

- I'm concerned about hiring new staff and having to make sure that they know this, can learn it or are even happy to do so.

- I'm concerned about having a decrease in the community size to debug issues. Had horrible experiences with this in the past with hybrid tech.

- I'm concerned with bugs being introduced or patterns being changed in the tool itself. Because it changes and touches everything, it will be a nightmare to rip it out or use something else and we'll be stuck with the issue. This seems to have happened with ReactiveCocoa where they made a change to their approach that seems to have caused a divide in the community, with people splitting off into other tech.

- In this app we have base Swift, with RxSwift and RxCocoa on top, with AlamoFire on top of that, with Moya on that and RxMoya on top again. This to me is too much when only looking at basic screens and networking. I would be concerned that moving to something more complex that we might end up with a tonne of dependencies.

- There seems to be issues with the server (nothing to do with RxSwift) but the errors seem to be getting caught by RxSwift and turned into very vague and difficult to debug console logs. "RxSwift.RxError error 4" is not great. Now again this could be a "way its being used" issue as oppose to an issue with RxSwift itself. But again were back to a big middle layer sitting between me and what I want to access. I've already had issues with login seeming to have 2 states, success or wrong password, meaning its not telling the user whats actually wrong. Now i'm not sure if this is bad dev or bad tools, but I get a sense RxSwift is contributing to it in some fashion, at least in this specific use of it.

I'll leave it there for now, any opinions or advice would be appreciated.

The web is just a fucked up place. Anytime i have an idea and wanna slap together an mvp, i always feel like web standards are just made by people who have no professional training and once every year come up with some bullshit so they dont get fired.

Figure 1: cors
You wpuld think that setting "access-control-allow-origin" to * would let, well, * through, like in every other field of programming, but no, make sure all 97 other headers match or you will just get a cors error. The server expects application/json and you didnt specify that? Fuck you, have a cors error. Both express and flask have specific packages addressing this one problem so i guess im not the only one.

Figure 2: frameworks
Remember reactive programming? Remember rxjs? No you dont because all frameworks reimplement rx with shadow dom fuckery. Did you know you can have your fucking templates with 5 lines of rxjs code? Amazing huh?

Figure 3: php
It still exists for some reason.

I'm freaking done trying to get Linux on my machine. I've tried every distro with many different versions of the kernel and I always run into the same problem on my desktop.

The computer super stutters for 2 seconds ish than freezes.

I've spent DAYS looking into this issue trying to find something. The worst part is that it can happen 5 minutes when I boot or 5 hours. At first I thought it was Compton. Then I thought I installed arch wrong. Maybe an update to the BIOS? How about downloading updated microcode? Maybe this obscure bug with AMD processors and setting power idle to typical? Nothing. I'm now behind on my school work because of the massive amount of time ive spent getting this fixed. It works just fine on my laptop, but it doesn't work on the machine I built to code with. I'm done. Give me Force Lightning, a red lightsaber, and call me a Sith baby because I'm joining the dark side. Here I come Windows.

For those who are wondering my setup:
Ryzen 7 1700
Rx 480
Asus x-370 prime
16 gb Corsair RAM

And no, Windows has never had this bug.

When you are retard and cross TX/RX lines, desperate measures will have to follow, like terminating hardware UART on start-up so that you can bit-bang over crossed TX/RX yourself...

Frustration Rant!

Because old hardware means learning the hard way sometimes, I've had to purchase more goodies.

On my last update, I installed the rs232 shield which may have inadvertently been wired backwards for Tx/Rx from what im used to. I assume it is backwards to most db9 serial ports because most Arduino or other projects you would do with a pi have serial "in" connections like old routers and devices that would be "controlled" rather than the other way around. Anyway, according to a video on youtube showing a guy turning an old machine into an IRC client via raspberry pi, this shield may be swapped. That means that instead of interfacing with the old machine via a null modem crossover cable, I need a straight cable with male db9 on both ends. I unfortunately tried using the null modem crossover cable which was reversing the reversed pins all over again. I hope these next few days are more fruitful now that I've bought a straight cable and db9/25 adapter.

The good thing is that I managed to get the pi to recognize its new serial port. I also dusted off my DOS skills and my serial card in the 5150 seems to work.

I literally banged my head after nothing worked. Im hoping that the tx/ Rx is solved soon.

Oh and that AT to PS/2 adapter will allow me to use by IBM original Model M Keyboarf rather than the fun model F.

As a junior dev from a sysadmin and security background, this is a list of software development concepts I never seemed to truly understand but hope to(rated from most intimidating to least):

1) Frontend web development and all the huge world of javascript frameworks and tools. - It's more overwhelming than the political geography of the Holy Roman Empire in the Middle Ages.

2) Machine Learning, Deep Learning and A.I- too much math that fucks with my brain.

3) low-level programming(kernel,drivers) - sounds extremely interesting but the code in assembly/C/C++ looks like Linear A Minoan hieroglyphics.

4) Rx(insert language here) - I never get why it is useful or why someone invented this. Seems interesting though.

5) Code Reflection - sounds like Thelemic magick.

6) Packaging, automation, build tools, devops, CI, Testing -seems too complicated. I just want to run an executable at the client or make a web app that does something. Why all this process?

Finally selling my gtx 1070 and going to swap to AMD, just wanting to know if anyone has heard anything about the RX 590 finally playing nice with linux?

Heard it was causing a lot of issues, just don't want to buy it and have more problems than I am with NVIDIA at the moment!

In Rx, what is the point of returning Single for all of our networking request responses, if every call to that method, first of all converts it to an Observable so that it can use flatMap, filters, combineLatest etc.

I get that Observable's have more overhead, Single can only return once, thats all clear. But is it not MORE overhead to create a Single, return it, convert it and now have the Observable we were trying to avoid in the first place.

I don't know if its just Rx I don't like, or how the team here is using it. But it is pissing me off, to no end, how massively overly complicated this is. It really feels to me like this is following a textbook approach while ignoring all the practical details.

<rant>
Next person to say "because its the Rx way", is getting a monitor thrown at their head.

My 2009 ThinkStation has been running loud for a couple of years now, reaching temps in the 70s-80s at max load (40s idle) with stock settings, fans spinning like jet engines to try to cool it. Only recently (today) did I consider that maybe there's dust stuck somewhere, so I took the fan off my cooler and began the hunt there.

IT WAS FUCKING COVERED. Half of the fin intake area behind the fan was completely clogged up with dust. I was starving the poor thing and I never figured out why until now.

I deep-cleaned the entire system, and now it's running a gentoo install with all cores maxed running compiler tasks... Fans are much quieter, barely above idle noise, the main difference is just pitch of the noise because of the higher RPMs.

I dont have the firmware installed to measure temps, but I will update once I get that data.

Specs, in case anybody is curious:

> Xeon W3520 4c/8t 2.67Ghz
> 8GB DDR3 1066MHz
> RX 460 2GB (my student-budget upgrade)
> Dual 500/750GB HDD

fucking hell, rx vega weighs like 300tons

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?

Question to all of you guys using linux:
Is it normal for my PC to use 100W power with just x11 running, nothing fancy open while when using windows it just takes about 60W. I didn't find anything about that on the web so I'm really concerned at the moment.
My hardware is a xeon e3 1230v5 and a amd rx 480. My guess is that the amdgpu drivers don't support AMDs low power thingie. What are your thoughts?

I told you guys that I would update you on my PiBM-5150 project. I figured out the hard way that my USB to DB-25 cable wouldn't cut it. Seems it is for printers and no matter how hard I tried it wouldn't work because of the path of the wires. After researching, it is apparent that the GPIO pins on the pi are configured for serial by default but it requires a little voltage change from TTY to RS-232. Rather than do like one of the videos I saw and solder junk to a bread board, I found a serial (rs-232) shield and 9pin output for the pi. Now, both computers are true rs-232 each. Instead of using a modem between them, I bought a null modem cable (crossover of Tx Rx signals) to interface the two machines directly. I'll update this evening to show it hopefully working.

Why do I make everything so expensive. I'm not a hardcore enthusiast, but at the same time I wont settle for "mainstream" and so I do weird unique things that end up costing more than they should

My mech keyboards are all DIY, I've spent $150-200 on 3 different occasions for 3 different keyboards. I think I'm settling down, but boy that was rough on my wallet.

Now I'm working on a custom workstation build, but I can't just use any normal tower because I ain't no normie. I want it to be SFF/portable so I'm planning on spending $250 just on the shoebox case (DAN A4-SFX). That's probably the most expensive part, besides maybe the GPU. Current plan is R7 1700 or 2700 with 16GB, RX 580 8GB, and 1TB NVMe, around USD$1200 total maybe

Just ordered 3 new setups for our upcoming office - parts will arrive next week, absolutely hyped 😍
Each setup includes Ryzen 7 2700X, 16GB TridentZ RAM, Samsung EVO 970 M2 SSD, RX 570 Armor 8GB, Be quiet CM 10 600W, 3x Riing 12 coolers, NZXT H500 case. Also a 4K 27" Samsung Monitor and a 29" LG Ultrawide. Kind of overkill for office PCs, but as we're also hobby game developers and had kind of a budget, we figured it will fit our needs more than enough 😄 Pictures of the builds coming up soon!

It's impossibru: I'm doing RxJava + RxKotlin + RxAndroid and I'm understanding it.

Somewhat.

My tests pass, at least that's something. It's not yet doing completely what I want, but the hardest part is behind me. 🤩

my new rig is more and more causing me issues:

- Ryzens fucking kill 9x and MS-DOS applications and the OSes themselves when they run unemulated, so they can't be run in a KVM. This makes them slow as shit, and in qemu-TCG's case, buggy as shit too. VMs can't reboot successfully, they have to be totally forced down and brought back up on TCG or they hang during the reboot. It also performs poorly. VERY poorly. The "shit runs full-speed like 65% of the time and it feels slow as fuck as video output is a stuttery blurry mess" type. This makes 2 projects problematic to complete and I have to remake 17 VMs in virt-manager now as vbox doesn't work with any virtualization method for a 9x/DOS guest now!

- For some reason my new RX 5500xt has an issue when it hits about 80% usage, the fans spin to 100% on it at 80% and taper off to like 5% when idle. Pretty standard stuff... except it's erroneously tied to... current load, not temperature. Hmm.

- Debian got an update that renames my ethernet device mid-boot. Up until just before the login screen, it's named "eth0". After that, it's named "enp8s0". This was hell to work around and idk why it does this.

I want an rx580 for my new pc build, but all of them are sold out...

Damn cryptominers, now I'm realy pissed!! 😠

It's here finally. Rx 580

I'm going to build a PC. Everything is done besides of the GPU.

I wanted to go full team red, but it turns out that the RX 5700 XT has a lot of driver issues.
I watched a hell lot of YouTube videos, benchmarks, forum posts, reddit, ...
Everyone is complaining about driver issues that haven't been fixed since the launch of the product.

That makes me want to go to team green and buy the NVIDIA 2070 SUPER GPU.

I post this as some sort of rant, but also as some sort of advice seeking post to double check my decision before I buy the 2070 SUPER.

My stickers on the top side of Mac. what are yours?

Sometimes in our personal projects we write crazy commit messages. I'll post mine because its a weekend and I hope someone has a well deserved start. Feel free to post yours, regex out your username, time and hash and paste chronologically. ISSA THREAD MY DUDES AND DUDETTES

Just a nice commit on a good friday.
Just a quickie
I dont know what im committing...

Oh god why... Why is it that every time I work with software defined radios, I keep on having to rely on not just incomplete, but at times misleading documentation 😩

Last time was GNU radio, with the doc telling me that I could define an input for a processing block using either a type or a (type, size) tupple, only for the actual code to scream at me in confusion upon my passing a tupple.
Now is that other SDR's SDK, which, as if being built upon eclipse wasn't bad enough, managed to make its serial communications confusing. Why can't you just let me set a callback to rx interrupts, you daft punks...

Excuse my question, but what advantage does RxSwif (or what ever Rx framework you use for a language) is better or helps in development than without using any Rx framework?

What's your opinion on functional shortcuts and 'hacks' in many languages, like map/reduce/filter, ternary operator, lambdas,inner/anonymous classes?

Imo they can make development faster and more efficent but they make the code very unreadable, especially if someone else has to read it, Therefore I try to use them only when it's appropriate. My dev friends use them too much and it makes reading their code a hellish experience, especially in Javascript with Rx.

So the tests for the AMD RX 7000 GPUs are out. Business as usual: superb for non-RT gaming given the price, crap at everything else - including energy efficiency in FPS/W.

Pro tip to the AMD marketing: you don't highlight features like energy where you suck relative to the competition. You point out your strong points. Admittedly, you don't have much to work with here.

Wouldn't be node js a good fit for a performant message queue, I mean it's async from the bottom up, a low memory footprint and good rx support? Or what specific does a good mq require?

I've gotta create a bidirectional communication protocol to link 2-3 RPis over GPIO. I have between 4-5 pins for TX and 45 for RX, so each directional bus is that wide.
Even better, I have to assume 4 bit bus length unless told otherwise, since 4 to 6 pins on the GPIO are usually used for serial/UART, COM and/or 1-pin communications (for use to get a console, not to throw data down.)

The best part?

Needs to be a Python library.

i wanna die

Any Kotlin fans out here? What's your favourite feature?

To me: coroutines and the flow API. I can't wait for the state flow and shared flow APIs to be released. Goodbye Rx! It'll come probably in the next release, which might come in a week already, because then JetBrains (Kotlin developer) hosts their online alternative to KotlinConf.

Dependency injection and RX java and all are cool.

But I like to do good object oriented programming.

And now there are kids in start ups who see devs doing good object oriented programming as retards.

Android as a platform provides everything that you need. Why abuse a simple app with all fancy stuff when you can accomplish stuff with simple oops which takes the same amount of time ?

Am I the one feeling this way ?

Some hardware experts here? Looking to upgrade my PC soon, and would like some opinion on the parts I chose. I'm going for a minimalistic Mini-ITX productivity build, but gaming also.
- CPU: Ryzen 7 2700X
- CPU Cooler: AMD Wraith Prism
- GPU: MSI RX 570 8GB Armor (already have it)
- RAM: 2x 8GB TridentZ RGB
- 1. SSD: Corsair Force MP510 240GB M2 SSD
- 2. SSD: Samsung EVO 860 1TB SSD
- PSU: Corsair CX550M
- MoBo: Asus ROG Strix B350-L Mini-ITX
- Fans: 6x Thermaltake Riing 12 RGB
- Case: NZXT H200i

I'm pissed at my laptop. Its using the on board graphics instead of the dedicated graphics card. I've searched everywhere and can't find a solution. I've tried just disabling the on board graphics in the device manager, but then I can't plugin external monitors. And on top of that when opening a game it doesn't even use the GPU it uses the CPU

Anyone have advice? The onboard is AMD Radeon R7 and the card is an AMD RX 560

While doing Rx swift!

I've just joined a new company out of despair after several month out of jobs without being able to even get interviews.
I've been warned about the code being a bit behind with modern Android stack, they needed to migrate from rx to coroutine and compose is not a priority at the moment.
Fine with it, I like handling and planning migration, that's a nice challenge.
But if only that were the only problems !! Far from it, the code is a formidable mess, I've never seen so much amateurism... Most of it was written from the previous Lead Dev who stayed there for years and touched everything with their very bad practices.
I don't even know where to start honestly...
While the code is in Kotlin, it stink Java. Nothing wrong about Java, but if you code in kotlin, you need to understand what kotlin try to achieve. And that's not the case here. There is freaking nullable everywhere, for no reason at all, the data classes contains lot of var in their constructors, equals are override to compare only one or 2 params and no hashcode override with it.
Sealed class, what for ?! Let me just write a List<Pair<Enum, Any>> and cast your any depending on the enum !
Oh and you know what, let's cast everywhere, no check, and for once no null safe, there is enough nullable in the code !

What about the reactive part ? well let's recreate a kind of broken eventbus with rx ! Cause why not ?!
The viewmodel observable don't contain data, they just contain enum for the progress of the states we're checking.
In the viewmodel function we update that enum states and emit it to be observed and make the data available as a var for the view to pick it up when needed.
But why put the business logic in the viewmodel, let's put in the views, and grab and check the variable contain in the viewmodel whenever it fits.
Testing the business logic ? uh let me just test my variable initialisation in the viewmodel instead.
The vm, the views, make about 2000 lines, the test over 3000, and not a single test really test the business logic in it ! I've made big refactoring we're all the tests stayed green, while the function are full of side effects ! WTF ?!
Oh and what about that migration from rx to coroutine ? well better not break the existing code and continue writting like rx, everything is cold flow ! We just need to store a boolean saying if we already did our call to the data layer then we decide to start our flow or not.
As for the RecyclerView, having too many viewHolder is just so annoying, let's put all our different views in one, and hide what we don't need.
Keystore has been push on the repo, but it's private no ? So who cares ?!
And wait i'm not done ! Some of the main brick of the apps depends on library that hasn't been updated for years, and you know what... yes they were hosted on Jcenter and it's only now that they decide to do something about it, we we're warned about the sunset of jcenter 2 years ago !!!!
So what about compose ? What do you want with compose ?! there is no design system in that app obviously, so don't even think about it !
And there... among all of that mess, I'm supposed to do code review... how the fuck do you do a code review when all the code that is around stink ?!
And there is so much more but by now I'm afraid you're thinking i'm just pissing on the old code like everyone... but damn I guarantee, that's the worst code I've ever seen, and i've work on more than 15 app from small to big on different contract with a lot of legacy code, but nothing that bad !

Ugh Android OS is so vast and intimidating, i feel so unsure about it even after 3 years of learning it.
Like now i am about to graduate, so i need to look for a job. Those companies require knowledge of libraries like data binding, dagger, rx fabric, etc the stuff that i never personally used in any of my personal projects because i was able to handle all my stuff by general programming knowledge.

At the same time the os itself is so large and full of apis that i want to learn and spend my time upon. Like Android stores data, renddrs media , its databases, its lifecycles, gradle building , manifest etc

Can any devs share how they are proceeding with this os? I always feel like i am floating on the surface and not diving deep enough :/

Rx killed the AsyncTask star

so am switching jobs as an Android dev from a company which made android libs (using almost 0 external dependencies and mostly java) to a company which makes android apps( and is probably using either rx/guava/ribs/hilt etc or the more fancy hilt/compose/coroutines/clean-arc etc. its either one of them depending upon the maturity of product)

B2C folks use tons of libraries in favor of delivering fast but learning about those libraries while taking new tasks and fixing bugs CAUSED by those libraries ( or their inappropriate usage) is a big PAIN IN THE FUCKING ASS.

I remember i had once became such a weird dev coz of my prev company ( before the current libraries one, which was also a B2C) .

on weekends i would come up with a nice app idea, start a new android studio project, and before writing a single line of useful code, i would add a bunch of libraries, gradle scripts and extensions .

that ocd will only settle once all the steps are done and i can see a working app after which i would write the code for actual code for feature implementation.

granted that these libs are good for creating robust scalable code, but most of the times those infinite kayers of seperation, inheritance and abstraction are not really needed for a simple , working product.

:/

i have also started reading about rxjava , and although i am repulsive to this library due to its complicated black box like structure, i find its vast number of operators nd built in solutions very cool.

at the end of the day, all i want is to write code that is good enough for monkeys, get it shipped without any objections and go back home.

and when you work on a codebase that has these complicated libs, you bet your ass that there will be thos leetcode bros and library lover senëõr devs waiting to delay the "go back home" part 😪

Fuuu!!!

I'm currently on elementary.

I have two monitors, one plugged to my Rx 560 and GPU and the other to onboard graphics.

Despite this my main monitor is rendered on the Intel inbuilt GPU and I have stuttery gui on my primary monitor.

(My second one is an old monitor and I can't find VGA to dvi converters, on Windows it just works so I haven't had an issue)

Please help me guys !

I am feeling a lot doubtful right now.

I am an average undergrad student who has been dedicating efforts in java/Android for most of my college life.

As of now i have decent command over java , launched 2 simple apps on playstore, worked as an android dev intern in 3 companies and make decent medium complexity apps. I will say i am 40-60% down the path of an expert native Android dev.

However apart from Android, am dumb as a stick. I know shit about ai,ml, web dev, js , react, hybrid stuff, and am not very good with competitive programming and system topics ( os, Algorithms, networking, etc)

So this closes a lot of doors for me. I can't apply to some top tier companies as they would either want expert competitive skills or expert Android dev skills.
I had bad experiences with startups which are usually willing take rejected students like me for the post of a droid dev... there is usually low packages , high pressure, and treatment like a slave

So i am very unsure what to do next. I have tried to learn web dev/ ai-ml-data sciences. They are not very interesting to me, but again, what is interest really :/

What should be my focus now?
A) I could be learning competitive and other interview related topics so that i could crack interviews of top companies , and later try to get a position of android developer there.

B) i could focus on become better in Android and start learning things that i don't know like rx, kotlin, etc. I could then hope to crack interview of medium sized app dev companies which would mainly focus on my android knowledge in their interviews

C) i could increase my skill set and learn web dev or ai/ml topics to increase my recruiter pool. It would be like option B, but i will have more medium sized companies willing to take me.

Currently i am in a shit storm. I am about to go into a mass recruiter company in which i have heard would be doing more or less data entry work

I'm trynna buid a new pc for data related works. I already have i7 8700k processor with decent cooler in Asrock z370 extreme 4 MoBo and 16 gb ram. I cant decide between RX 5700XT and RTX 2080 Super.

Please help. Your valuable opinion is highly appreciated.

Been working on redoing my desktop lately. Currently the specs are:
-FX-8350
-Gigabyte GA-970A-DS3P motherboard with a broken USB 3.0 header lmao
-GTX 660 (Gonna upgrade to an RX 580 at some point, I don't do any hardcore gaming so I know I don't need a top of the line GPU)
-Crucial BX500 240gb SSD
-WD 500gb HDD (gonna upgrade to a bigger one eventually)
-Some like $60 Dynex PSU I bought a while ago, waiting on my Corsair RM650x to come in

At this very moment, it's running Windows 7 Ultimate x64. Once I get to a point where I'm happier with the build, I'll switch it over to Linux and start ricing. It has Windows right now cause I'm just using it for some games and when I last fucked with the hardware, it was the middle of the night so I didn't want to spend too much time setting up a Linux distro the way I want it and everything right then, just putting that off for later (especially cause I use Arch btw)

I have been playing some Half Life 2 lately. I forgot how fucking fun that game is.

Aside from my PC, my birthday was technically yesterday (it's about 2:30AM as of writing this, and I've been up for a while, so I still consider it today). Now I'm 2 years away from being able to legally drink (and smoke since the law change, although I still do both anyways).

I'm gonna stop rambling. Life is fairly decent right now. Not too much to "rant" about except for shit with my roommates, but I won't bore everyone with that

Well, it's me again from yesterday, so i did a minimal debian install and i think i did what the debian site said regarding the graphic drivers for ati but here's the deal:

xrandr --listproviders only shows the intel provider, the dedicates amd gpu [RX 550] is not shown. (Also on doing lspci it is shown as a Display controller instead of vga adapter.)

+ the laptop heats a lot too

Any idea regarding what should i do? Or maybe where do i get help?

Off topic question: What is the difference between vga adapter and display controller??

Yo mama so fat, if one would create an observable from her it would cause backpressure

Okay, so debian is just fucked by default then.

Created a Debian 10 persistence stick, and I'm having the fucking xorg issues ("No screens detected", xrandr says the same) i've had every fucking time i've installed debian, except a simple round of dpkg-reconfigure isn't fixing it this time.

Suggestions?

Things tried:

- dpkg-reconfigure <every package even remotely related>
- X -configure
- installing all firmware from linux-firmware repo
- reinstalling everything remotely related (with both reinstall and purge/install)
- Wayland ("failed to create compositor backend")
- creating my own xorg configs and driver-radeon configs and all that shit with my screen explicitly defined
- remaking the stick with a redownloaded ISO
- actually installing it to a HDD first
- crying in frustration
- different monitors
- someone else's machine (both AMD GPUs, mine's an R9 380, his an RX 3-digit something-or-other)
- an NVIDIA card (other tester threw his old 1080TI in his PC, set up all the drivers and shit, and nothing fucking changed)

what is this, Fedora?
