Still trying to get good.
The requirements are forever shifting, and so do the applied paradigms.
I think the first layer is learning about each paradigm.
You learn 5-10 languages/technologies, get a feeling for procedural/functional/OOP programming. You mess around with some electronics engineering, write a bit of assembly. You write an ugly GTK program, an Android todo app, check how OpenGL works. You learn about relational models, about graph databases, time series storage and key value caches. You learn about networking and protocols. You void the warranty of all the devices in your house at some point. You develop preferences for languages and systems. For certain periods of time, you even become an insufferable fanboy who claims that all databases should be replaced by MongoDB, or all applications should be written in C# -- no exceptions in your mind are possible, because you found the Perfect Thing. Temporarily.
Eventually, you get to the second layer: Instead of being a champion for a single cause, you start to see patterns of applicability.
You might have grown to prefer serverless microservice architectures driven by pub/sub event busses, but realize that some MVC framework is probably more suitable for a 5-employee company. You realize that development is not just about picking the best language and best architecture -- It's about pros and cons for every situation. You start to value consistency over hard rules. You realize that even respected books about computer science can sometimes contain lies -- or represent solutions which are only applicable to "spherical cows in a vacuum".
Then you get to the third layer: Which is about orchestrating migrations between paradigms without creating a bigger mess.
Your company started with a tiny MVC webshop written in PHP. There are now 300 employees and a few million lines of code, the framework more often gets in the way than it helps, the database is terribly strained. Big rewrite? Gradual refactor? Introduce new languages within the company or stick with what people know? Educate people about paradigms which might be more suitable, but which will feel unfamiliar? What leads to a better product, someone who is experienced with PHP, or someone just learning to use Typescript?
All that theoretical knowledge about superior paradigms won't help you now -- No clean slates! You have to build a skyscraper city to replace a swamp village while keeping the economy running, together with builders who have no clue what concrete even looks like. You might think "I'll throw my superior engineering against this, no harm done if it doesn't stick", but 9 out of 10 times that will just end in a mix of concrete rubble, corpses and mud.
I think I'm somewhere between 2 and 3.
I think I have most of the important knowledge about a wide array of languages, technologies and architectures.
I think I know how to come to a conclusion about what to use in which scenario -- most of the time.
But dealing with a giant legacy mess, transforming things into something better, without creating an ugly amalgamation of old and new systems blended together into an even bigger abomination? Nah, I don't think I'm fully there yet.8 -
It's been three weeks now that „SPRING“ is over and Nerdism won over our interior decorations. Neither wife nor friends and family noticed. But I do. Every morning. This time I made an impact to our decoration. This single time4

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.question functional programming reactivex java library reactive ios functional swift android rxswift rxjava18 -
The amount of energy spent to just write ‘Hi’ and click a send button is so big that we should consider banning of sending hi messages.
Instead of just saying “Hi!” we are now using analog to digital preprocessors that convert it to bunch of 0 and 1 to send it over communication layer and deliver it to other human being that will convert it from digital to analog by reading it but that is simple.
By sending message using phone we also:
- save it to local phone
- convert it to couple protocols
- transmit it over air so make connection to internet provider services that would generate logs on this provider as well as whole routing table before it gets to the target person
- save it on messaging provider disk
- probably be processed by filters by provider, sometimes be reviewed or listened by third parties and also processed in bulk by artificial intelligence algorithms
- finally delivered to target phone and saved there where that person would just change this text to their inner voice and save it
- sometimes encrypted and decrypted
- sometimes saved on provider
- sometimes saved on phone manufacturer cloud backup
- don’t get me started on people involved to keep this infrastructure in place for you just to say hi
There are also some indirect infinite possibilities of actions for example:
- emit sound and light that can lead to walking from one room to other
- the floor in your house is destroyed cause of it so you need to renovate your floor
- sound can expose your position and kill you if you’re hiding from attacker
- sound can wake you up so you wake up in different hours
- it can stop you from having sex or even lead to divorce as a result simple hi can destroy your life
- can get you fired
- can prevent from suicide and as a result you can make technology to destroy humans
and I can write about sound and light all day but that’s not the point, the point is that every invention makes life more complicated, maybe it saves time but does it really matter ?
I can say that every invention we made didn’t make world simpler. The world is growing with complexity instead.
It’s just because most of those inventions lead to computer that didn’t make our world simpler but made it more complicated.1 -
I knew programming was for me, MUCH later in life.
I loved playing with computers growing up but it wasn't until college that I tried programming ... and failed...
At the college I was at the first class you took was a class about C. It was taught by someone who 'just gets it', read from a old dusty book about C, that assumes you already know C... programming concepts and a ton more. It was horrible. He read from the book, then gave you your assignment and off you went.
This was before the age when the internet had a lot of good data available on programming. And it didn't help that I was a terrible student. I wasn't mature enough, I had no attention span.
So I decide programming is not for me and i drop out of school and through some lucky events I went on to make a good career in the tech world in networking. Good income and working with good people and all that.
Then after age 40... I'm at a company who is acquired (approved by the Trump administration ... who said there would be lots of great jobs) and they laid most people off.
I wasn't too sad about the layoffs that we knew were comming, it was a good career but I was tiring on the network / tech support world. If you think tech debt is bad, try working in networking land where every protocols shortcomings are 40+ years in the making and they can't be fixed ... without another layer of 20 year old bad ideas... and there's just no way out.
It was also an area where at most companies even where those staff are valued, eventually they decide you're just 'maintenance'.
I had worked really closely with the developers at this company, and I found they got along with me, and I got along with them to the point that they asked some issues be assigned to me. I could spot patterns in bugs and provide engineering data they wanted (accurate / logical troubleshooting, clear documentation, no guessing, tell them "i don't know" when I really don't ... surprising how few people do that).
We had such a good relationship that the directors in my department couldn't get a hold of engineering resources when they wanted ... but engineering would always answer my "Bro, you're going to want to be ready for this one, here's the details..." calls.
I hadn't seen their code ever (it was closely guarded) ... but I felt like I 'knew' it.
But no matter how valuable I was to the engineering teams I was in support... not engineering and thus I was expendable / our department was seen / treated as a cost center.
So as layoff time drew near I knew I liked working with the engineering team and I wondered what to do and I thought maybe I'd take a shot at programming while I had time at work. I read a bunch on the internet and played with some JavaScript as it was super accessible and ... found a whole community that was a hell of a lot more helpful than in my college years and all sorts of info on the internet.
So I do a bunch of stuff online and I'm enjoying it, but I also want a classroom experience to get questions answered and etc.
Unfortunately, as far as in person options are it felt like me it was:
- Go back to college for years ---- un no I've got fam and kids.
- Bootcamps, who have pretty mixed (i'm being nice) reputations.
So layoff time comes, I was really fortunate to get a good severance so I've got time ... but not go back to college time.
So I sign up for the canned bootcamp at my local university.
I could go on for ages about how everyone who hates boot camps is wrong ... and right about them. But I'll skip that for now and say that ... I actually had a great time.
I (and the handful of capable folks in the class) found that while we weren't great students in the past ... we were suddenly super excited about going to class every day and having someone drop knowledge on us each day was ultra motivating.
After that I picked up my first job and it has been fun since then. I like fixing stuff, I like making it 'better' and easier to use (for me, coworkers, and the customer) and it's fun learning / trying new things all the time. -
Anyone with good understanding of hardware and/or an operating systems network protocols please assist me. I have questions
When using socket api I know it’s not the actual sockets sending the data but the socket api tells the network protocol to send, receive, listen, connect, etc well what I want to know is how that networking protocol works within the operating system
My second question is more an extension of the first. After the operating system knows what the socket api wants to do and wants to do it how does the transmission and receiving work on the physical layer within the hardware
Idk if what I’m asking makes sense. But if anyone also has any resources or a link that’ll help me on the subject I’d appreciate it. I haven’t found anything on the subjects myself19
