So this was a couple years ago now. Aside from doing software development, I also do nearly all the other IT related stuff for the company, as well as specialize in the installation and implementation of electrical data acquisition systems - primarily amperage and voltage meters. I also wrote the software that communicates with this equipment and monitors the incoming and outgoing voltage and current and alerts various people if there's a problem.

Anyway, all of this equipment is installed into a trailer that goes onto a semi-truck as it's a portable power distribution system.

One time, the computer in one of these systems (we'll call it system 5) had gotten fried and needed replaced. It was a very busy week for me, so I had pulled the fried computer out without immediately replacing it with a working system. A few days later, system 5 leaves to go work on one of our biggest shows of the year - the Academy Awards. We make well over a million dollars from just this one show.

Come the morning of show day, the CEO of the company is in system 5 (it was on a Sunday, my day off) and went to set up the data acquisition software to get the system ready to go, and finds there is no computer. I promptly get a phone call with lots of swearing and threats to my job. Let me tell you, I was sweating bullets.

After the phone call, I decided I needed to try and save my job. The CEO hadn't told me to do anything, but I went to work, grabbed an old Windows XP laptop that was gathering dust and installed my software on it. I then had to build the configuration file that is specific to system 5 from memory. Each meter speaks the ModBus over TCP/IP protocol, and thus each meter as a different bus id. Fortunately, I'm pretty anal about this and tend to follow a specific method of id numbering.

Once I got the configuration file done and tested the software to see if it would even run properly on Windows XP (it did!), I called the CEO back and told him I had a laptop ready to go for system 5. I drove out to Hollywood and the CFO (who was there with the CEO) had to walk about a mile out of the security zone to meet me and pick up the laptop.

I told her I put a fresh install of the data acquisition software on the laptop and it's already configured for system 5 - it *should* just work once you plug it in.

I didn't get any phone calls after dropping off the laptop, so I called the CFO once I got home and asked her if everything was working okay. She told me it worked flawlessly - it was Plug 'n Play so to speak. She even said she was impressed, she thought she'd have to call me to iron out one or two configuration issues to get it talking to the meters.

All in all, crisis averted! At work on Monday, my supervisor told me that my name was Mud that day (by the CEO), but I still work here!

Here's a picture of the inside of system 8 (similar to system 5 - same hardware)

Worst advice: "Forget Android, specialize on BB10, that's the future'

TLDR;
Wrote a slick scheduling and communication system allowing me to assign photography resources based on time and location.

I'll tell you a little secret ... I'm not actually a dev. I'm a photographer, pretending to be a dev.

Or ... perhaps it's the other way around? (I spend most of my time writing code these days, but only for me - I write the software I use to run my business).

I own a photography studio - we specialize in youth volleyball photography (mostly 12-18 year old girls with a bit of high school, college and semi-pro thrown in for good measure - it's a hugely popular sport) and travel all over the US (and sometimes Europe) photographing.

As a point of scale, this year we photographed a tournament in Denver that featured 100 volleyball courts (in one room!), playing at the same time.

I'm based in California and fly a crew of part-time staff around to these events, but my father and I drive our booth equipment wherever it needs to go. We usually setup a 30'x90' booth with local servers, download/processing/cashier computers and 45 laptops for viewing/ordering photographs. Not to mention 16' drape and banners, tons of samples, 55' TVs, etc. It's quite the production.

We photograph by paid signup only - when there are upwards of 800 teams/9,600 athletes per weekend playing, and you only have four trained photographers, you've got to manage your resources!

This of course means you have to have a system for taking sign those sign ups, assigning teams to photographers and doing so in the most efficient manner possible based on who is available when the team is playing. (You can waste an awful lot of time walking from one court to another in a large convention center - especially if you have to navigate through large crowds - not to mention exhausting yourself).

So this year I finally added a feature I've wanted for quite some time - an interactive court map. I can take an image of the court layout from the tournament and create an HTML version in our software. As I mouse over requests in one window, the corresponding court is highlighted on the map in another browser window. Each photographer has a color associated with them. When I assign requests to a photographer, the court is color coded with the color of the photographer. This allows me to group assignments to minimize photographer walk time and keep them in a specific area. It's also very easy to look at the map and see unassigned requests and look to see what photographer is nearby.

This year I also integrated with Twilio and setup a simple set of text shortcuts that photographers can use to let our booth staff know where they are, if they have memory cards that need picking up, if they need water/coffee/snack, etc. They can also move assignments on their schedule or send and SOS for help if it looks like they aren't going to be able to photograph a team.

Kind of a CLI via the phone. :)

The additions have turned out to be really useful and has made scheduling and managing the photographers much easier that it was in the past.

5 years later I'm still wondering what programming language I should specialize in. Fml.

The fact that this week's rant topic exists is the exact reason I never do freelance work. It always ends in horror.

I don't believe good fullstack devs exist. A good junior will assess their talents/passions and specialize to become a senior. They'll keep checking the rest of the market from the corners of their eyes and start moving when necessary. But eventually, focus and specialization is a must.

If that's true for the field of development... why would I invest time in marketing, support, sales, PR, legal?

Maybe you can earn a bit more gross income in freelance work — but I see my employer as a service provider, I "hire" them so I don't have to manage phone calls, lose sleep over court cases, play product owner or worry about getting paid.

While this wasn't technically a real client, it's still one of the most insane requests I've ever had.

I chose to specialize in software engineering for the last year and a half of my degree, which meant a lot of subjects were based around teamwork, proper engineering practises, accessibility, agile methods, basically a lot of stuff to get us ready to work in a proper corporate dev environment. One of our subjects was all about project management, and the semester-long coursework project (that was in lieu of a final exam) was to develop a real project for a real client. And, very very smartly, the professors set up a meeting with the clients so that the clients could tell us what they wanted with sixty-odd students providing enough questions. They basically wanted a management service for their day-center along with an app for the people there. One of the optional requirements was a text chat. Personally not something I'm super interested in doing but whatever, it's a group project, I'll do my part.

The actual development of the project was an absolute nightmare, but that's a story for another day. All I'll say is that seven juniors with zero experience in the framework we chose does not make a balanced dev team.

Anyway, like three months into the four-month project we've got a somewhat functional program, we just need to get the server side part running and are working our asses off (some more than others) when the client comes in and says that 'hey, nice app, nobody else has added the chat yet, but could you do voice recognition okay thanks?'.

Fucking.
Voice.
Recognition.

This was a fucking basic-ass management app with the most complicated task being 'make it look pretty' and 'hook up a DB to an API' and they want us to add voice recognition after sitting on their ass for three months??? The entire team collectively flipped its shit the second they were out of earshot. The client would not take no for an answer, the professor simply told us that they asked for it and it was up to us whether we delivered or not. Someone working on the frontend had the genius idea of 'just get them to use google voice recognition' so we added the how-to in the manual and ticked the requirement box.

What amazes me about all that is how the client probably had no idea that their new last-minute request was even a problem for us, let alone it being in a completely different ballpark in terms of implementing from scratch.

I have previously mentioned my weird co-worker. He likes to come up behind people and shoulder surf, asking "whatcha up to, buddy?".

He also thinks he's a manager, which explains a lot I guess. I half expect him to walk around with an " Initech" mug saying "Yeah....if you could just have those TPS reports done by lunch, that would be greaaat".

YOU ARE NOT MANAGEMENT. YOU DO NOT KNOW WHAT I SPECIALIZE IN. GO FIX A PRINTER, GAH DAMMIT.

...and he mumbles.

I'm not perfect though, so I'm sure I have weird quirks about me.

Get a call from a customer asking if I can come check out her “printer”. Okay...
Get there and it’s not just a printer but an embroidery machine - never worked on them in my life and I’m not embarrassed to admit that.
I express that to her but tell her that I’ll definitely check it out and I get the reply - “you own a repair shop and have never worked on one of these, I don’t feel comfortable with you working on it.” - even though she had tried “fixing it” and completely fucked up the application and printer moreso than when it had originally stopped working.

Alright, bitch... I’m sorry that I haven’t worked on every fucking embroidery machine that’s ever been made. I apologize that I’m not familiar with your fucking machine, but if you would give me some time I assure you I can resolve your fucking problem; I imagine it’s (l)user error anyway. But no, you go ahead and send it off to the company that made it with a minimal charge of XXX$ and let them resolve your problem.

Yes, I run a computer/printer/phone repair shop, but that doesn’t automatically mean that I specialize in your FUCKING problem, but I can assure you I’d handle it.

Her - “You’re going to charge me when you didn’t even work on it?!”

Me - “I’m sorry, but I drove out here expecting to work, you declined the work; but there’s still a charge for having me come out here. Yes, you will be getting a bill. If you’d like me to work on it and help you resolve the problem, I’d be more than happy to.”

Her - *rolls eyes*

FUCK YOU!!!!

The more I look into Windows 11 the more I hate it. There's just 1 (one) more thing that's wrong with it every time I look.

It's a security and ethical nightmare. I almost wish I didn't specialize in computer recovery & cybersecurity.

So thankful that my high-end gaming-built PC is apparently "not compatible" with Windows 11. Oh, you don't want to break my computer and ruin my entire life? That's actually a complement, man.

I just noticed that my desktop still has a DVD-RW in it that I never used.. which led me to think, I've got here like 5 DVD-RW's as well as 5 CD-RW's, but I never use them. Are there still any uses for them? Long-term backup storage for example? I've heard somewhere that data rot can happen over the course of a few years.. but would it really be a problem? I mean I've had these for over a year already and they look healthy to me. That said, they've never been used and just sat on the top of my desk in their enclosures all the time.

FWIW, I'm having 10TB of storage (as well as some other smaller stuff here and there.. maybe 500GB or so) in various hosts and 3 mirrors, so the need for backups is already fulfilled.. it's merely a curiosity of mine as in "ah, I still have these things huh".. so yeah.

I think that I've bought these DVD's for something like €6 for 5 pieces in a local store that doesn't specialize in this sort of thing, so I'm fairly certain that I could get them for cheaper elsewhere.. think the likes of AliExpress etc. Would they be a viable technology to maybe still invest in over hard drives for long-term storage purposes, considering that the cost of a hard drive these days is only €50 for 1TB? But I guess that tapes would be better for this purpose, no?

Why in the world IT work is so stressful?
I never been like that since I start developing code professionally, 8 years ago.
Since then, I had many health problems due stress, and some were really scaring (heart problem).

I'm trying to adapt to a healthier way of work, but I'm starting to doubt if that is possible.

Work in technology seems cruel and soulless sometimes. The constant pressure to learn new things all the time, to specialize in a lot of skills, simultaneously. The urgency nature of ALL tasks - even a simple form field slightly out of place seems to be an issue of life and death for clients.

Easy and quick communication made some people lost boundaries and respect. Many times I received calls and messages after midnight, about things like elements alignment.

And the worst is when clients blame you about their business problems. If they are not selling well this week, it's fault of the website you did ( which they are using for months now).

This actually happened to me today, first thing in the morning. After I slept just 3h, because I worked until late yesterday (oh yeah many more of these life/death updates).

What happens in this industry? Will this ever be different some day?

What is this hate towards fullstack developers ? I suppose more you know the better ? I think you can specialize later, based on your work task.

Fullstack is the way for learning addicts as me.

Just had a great interview :)

The guy was really cool, asked actually relevant questions (my learning process, what I specialize in, etc), talked about the tech they'll be using and none of that "wHaT aRe YoUr WeAkNeSsEs?" bullshit.

He seemed to like me, he seemed to like the fact that I've been programming for a long time even though I'm in my second semester in college and he also seemed to like that I'm somewhat of a Swiss army knife, a jack of all trades but master of none.

I just I was a bit too informal in the interview but whatever. I'm not taking this very seriously, if I get the job I get the job, if I don't that's fine too.

Haven't ranted in a while so here it goes.

Head of product took me (senior dev) to a high value client workshop/demo session and over the course of two days found the reason behind why the dev team has been pushed to the limit as of late and sales/product team has been making promises to clients without checking with dev leaders on reasonable delivery dates on massive new features.

I tried my best to manage expectations by differing talking about delivery dates by saying "lets discuss that with the team" rather than giving out dates right now. But as soon as the meeting ends he sends an email to the client confirming delivery dates on features that we have done no research on or even specialize in!

Please tell me this is not how well established businesses work or is that the new reality of things. In either case I wanna find a new job :/

Well, I wanna specialize in low-level software as I get older. Everyone is telling me to go out and learn a processor architecture. I'm willing to be patient, so I do what people recommend to me and I download the Intel x86_64 manual. I was excited... UNTIL I REALIZED THE MANUAL WAS 4474 PAGES LONG! Like, how am I supposed to jump into assembly, machine language, and low-level programing with a beginner's task like that? I cannot find ANY resources online to simplify the transition, and college sure ain't gonna teach me anytime soon.

My first time doing a pair-programming for uni assignment.
My partner is actually smart (a Mechanical Engineering guy), except when it comes to programming :
1. Don't know how to spell FALSE
2. Don't know how to create array in Matlab
3. Poor variable naming
4. Redundant code everywhere
5. Not using tabs
6. Stealing my idea and spit it again in my face after claiming it as his idea
7. Mansplaining every line of his code like I am a stupid person who never sees a computer before.

He said he has an experience in Matlab, wants to specialize in Robotics and taking several ML classes. What did they teach anyway in class to produce a shitty programmer like him?

Thankfully despite his being an arrogant shitty guy, he still manage to get our code to works.
That's good because if not, then I will happily push his head under water while slowly watching him drown.

🤨

I have "we do not outsource any development" very clearly written multiple times on my LinkedIn profile and yet I still get 10-11 messages a day asking me to hire their sketchy Ukrainian
/indian software devshop, moreover to handle my fucking PHP MySQL needs (I very specifically write multiple times on LinkedIn and elsewhere that we do not use those tools). I've just stopped accepting requests from India and Eastern Europe, and if their headline mentions recruitment, anything "specialist", or blockchain that's an automatic ignore.

The funniest part is that they all say the same "we specialize in your needs" are you fucking kidding? If you read any part of my company profile or my profile you'd know that your specialty is anything BUT our needs fuck right off

Edit: I'm going to also specify that I'm a broke college student with a tiny software startup, so not only can I not afford their devshop but also why would I outsource the only thing we do?

You know, I've really been thinking about renouncing my love for Microsoft's products. I got into the tech world through them, so their stuff was all I really knew. It's like a non-dev growing up using Mac and iPhone. You don't really know what other hardware and software can do (especially since Microsoft is now acting a LOT like Apple nowadays). Ever since they killed Windows Phone, I started seeing past the rose-colored glasses. They've annoyed me with one slip-up after the next. The only things that have kept me tied to them are my Windows Insider membership, and their developer platform. Now that I've seen things like Fuchsia and Linux, I realize that the way Microsoft is going about technology is painful to developers and consumers alike, and this is now beginning to hurt their bottom line. I'm sick of it.

The issue is that if I leave the Microsoft platform, I will have no time to waste. I spent the last 2 yeas cozying up to them, and now I will need to find other platforms, languages, and utilities to build a portfolio from. This also means that I will despise pretty much every major tech company for different reasons (Apple for locked-down hardware, Microsoft for locked-down software, Google for it's monopolistic actions and its unfair policies and terms, Amazon for its invasiveness, etc). If things get worse, I'll probably end up going to Linux and joining the open-source community. The only worry I have is what I'll do for a career. I'm almost halfway to getting an Associates in Computer Science, but where do I go from there? Can't make a living open-source (unless I get patrons, which is unlikely), will probably abandon my dream of joining Microsoft or Google, and I don't currently specialize in any particular area of development yet. I want to spend my life dealing with tech and software. But right now, I've got next to no plans. I've got a lot of thinking to do...

tl;dr Why Linux?

So yeah, another Linux question. I love C# and been doing some WPF and Xamarin stuff and planning to learn ASP.NET, but why do I hear that Linux is better than Windows for web dev. Why should I learn it especially if I want to specialize in .Net? Sorry just a student and I heard Microsoft is bringing a lot of Linux goodness to Windows and I wonder why.

Id happily give up 10% of any prospective salary if it meant that my job hunting was handled by an agent who is somewhat competent in the concepts of programming and primarily motivated to secure the highest possible salary for me. Humanity is really good at figuring out how to delegate tasks so that individuals can specialize. Why can't I specialize in programming and delegate salesmanship?

To create an abstraction simple enough to make complex business logic challenges solvable for non programmers.

The issue I see today is programmers solving problems they don't understand as well as the user. I think two ways might be taken:
- Programmers specialize in other fields and solve problems there
- Other professionals create their own software

Both will happen in the future (IMHO) and I want to help the second happening.

Note: Excel does this really well, but I think we can so quite better today.

I just came out... as a senior developer. Got a promotion and that's great. But I have been a generalist software engineer so far. I do frontend, backend (which is what I'm best at), some devops, management etc etc. But as a senior dev, I'm starting to feel that I have to specialize in something. I'm the guy who can do anything, but when discussing about tech stuff the other senior devs looks more "smart" (it's only one of the small things that frustrate me). I like being generalist, but I'm starting to feel the necessity of specialzing and be a reference in some technology, contributing more to company frameworks, open source, etc.

I'm getting to the point where I'm going to have to specialize in either front-end or back-end and move away from being a full stack developer. At least that's my thought since the startup is growing. Of course there's always the option that I get placed as a lead to oversee a whole project, but that's not guaranteed.

Startup world problems.

Computer science has so many fascinating fields I can't decide which path to specialize on :/

Question for game developers 🙄
I wanted to try game development a few years back, started watching unity3D tuts, but I realized quickly that I can't actually do anything, because I don't have the skills to design animation and draw ui, and it was stupid to buy components online before I knew what I'm doing.. so I left it. Was I wrong? How did you start? Is it possible to make a game on your own, or do you need a team with members who each specialize in its own area (code, design, animation, music, etc.) And if team is needed, then how do you even start learning? Thanx

1. Extend my infosec knowledge further and try getting more work in that area (and less as a dev).
2. Specialize more, dabble less.
3. Learn more !dev skills (military/political history mostly)

Hey I have a career dilemma, was wondering if anyone experienced that and if anyone could give a tip on how to resolve it maybe.

TL;DR: I'm a Front End dev, who wants to become an expert in everything but obviously can't. What do I do? How do I choose what to learn?

Longer version. I started with Front End. Now i'm doing alright with Vue, React, bit of Angular, and other related to the stack tech. Then I started learning python because of a project I was doing (personal client). Didn't go far with this one. I still find it interesting esp. in the machine learning context, which I also want to do. Now I'm studying .NET, because of a project I'm currently doing at a company (full time, I'm doing ReactJS front end there tho). And I'm also studying for GCP exam, because I wanna know how to deploy solutions to the cloud. But one also needs to secure them, so I'm looking at some courses on Cybrary, in a search for appropriate courses.

I feel overwhelmed and unproductive. I feel like i need to specialize just in one field with some general knowledge about other areas. So I feel like I have to select what I do/learn carefully.

Any thoughts? How did you plan your career? What kind of goals did and do you set for yourself? Are you happy with those now once you achieve them?

I'd love to hear some stories. :)

In today's job interview for an apprenticeship for the "Anwendungsentwicklung" position where they specialize in SAP systems (ABAP).

They told me that this position is a new thing in their company and that they want me, once I agree with their contract (which they will send later), to take responsibility for that.

I'm fine with that.

Now comes the part that is bugging me. They also said that the IT manager does not want to be disturbed often, if I have questions.

(I mean I will definitely have some questions. I am an apprentice after all, right? Like why should I join your apprenticeship program, if you refuse to teach me stuff? I can study on my own, as well and not be in your program.)

Just a few times and that's it. They admitted that they do not know much about that position and that I have to learn most things myself. No books and no other resources. They also do not know where the school is going to be yet.

The people in the interview I've spoken to where nice and we made some jokes here and there, but the fact that the company does not want to support me in an apprenticeship is saddening.

I do not know...maybe I'm just too concerned and this is normal day to day stuff for apprentices, but from what I have read about apprenticeships this is not the right thing to do as a company on the internet.

Correct me in the comments, if you think differently.

I will use this company as a last resort.

Area of focus?
Whatever the client currently needs.
Because, who has time to specialize when there are bills to pay?

I'm a self-taught frontend developer with 1,5 - 2 years of experience in JavaScript / Vue.js development. Pretty cliche in 2023 and I can actually feel this now when it comes to the job market. It's brutal at the moment.I moved to Germany for a specific job but got laid off a few weeks ago due to a lack of projects and actual things to do. And here I am right now: tons of job applications, 4-5 interviews a week, zero success.

I'm thinking about getting some warehouse job or anything for the time being, and start freelancing in my spare time. Instead of this oversaturated JavaScript landscape, I would get into PHP (not as "hip" so less competition, backend, no new tools every 6 months), SQL, or hyper-specialize in CSS - something I like quite a bit but have seemingly zero value to employers.

I actually made a simple website for a small business when I was getting started with frontend, and he was super happy with the end result. I also did some language tutoring, that was quite rewarding as well. So freelancing is definitely fun, I enjoyed it much more than fearing layoffs or trying to force a fake-ambitious attitude on my 30th interview that most probably won't lead me anywhere. :D

Is the frontend job market really this oversaturated? (I know, I know... It's not difficult for competent, skilled, and experienced devs with CS degrees) Is being a CSS specialist, PHP-developer, or SQL-magician on fiverr/upwork/etc. a viable freelancing path? I've heard good and bad about these platforms, the competition there, etc. If not, where should I start?

What do you think? Any input is much appreciated. :)

I feel like most people on here specialize in Javascript since that's what seems to be discussed the most here.

Is it possible to learn all of Java's capabilities? I feel it's such a versatile language that one can only specialize in certain areas.

I was just wondering what languages are most apt for building a group of web applications that will manage huge amounts of data, represent them in graphical form, and through repetetive learning, state trends or detect negative trends and suggest measures against such negative trends?
In simple words, where should I start in the development of an environment where data can merge with machine learning and website's with an aesthetic interface? How many people will such a project require and in what areas will these people have to specialize in?

Finally decide whether to specialize in game development or security. Alternating every month is getting boring...

I wish I’d found a way to specialize in c/c++ with a focus in hardware design and coding

From the career point of view, I've seen many programmers, more or less, in the long run, specialize in the industry|ies they've been working, so the business practices, ins and outs and logics became part of their strong point in that|those industry|ies.

But I found myself on the opposite side, I could care less about the business's practices, etc. because in the end I'm mostly passionate about reaching some technical satisfying accomplishment or a novel approach to solve some kind of problem or just learn new approaches.

So when I'm handed info mostly focused on business practices|logics I just boringly read through it.

How about you?

Obviously business problems and technical feasibility to solve them overlap. But wouldn't be better to have people capable to express their issues more from technical points of view than talking nonsense to someone who's clueless about the business <.<?

when the swift language cannot infer the generic type from the invocation, it also doesn't want you to explicily specify generic type in the bracket...

says i have a method:
```
func createDeferred<T>() -> ABC.XYZ.Deferred<T>
```

then if you call it like this:
```
let dfd = createDeferred()
```
It complaints that it cannot infer generic type T, which make sense.

But it also doesn't want you to code it this way:
```
let dfd = createDeferred<Int>("countProperty")
```
if you do so, it mumbles gibberish: "Cannot explicitly specialize a generic function".

What it actually trying to say is, you should put the type somewhere else so that it can show off its smartness to "infer" it from there:

```
let dfd: ABC.XYZ.Deferred<Int> = createDeferred()
```
with a few more typing and findout what exact type it is, it finally works.

the moral of the story is, in order to communicate with the wonderful work apple genius made, you don't tell it what is the answer straight away, that's defiance, you must hide the answer somewhere intricately and let the smarty swifty swift to find it out for you.

It makes sense to learn AI and its mathematical basis (statistics and linear algebra) or unless I want to get a degree on the topic I’m wasting my time? If the answer is yes what are the best online resources/books which I can use?
To clarify I don’t want to specialize there and work as a “AI/data science specialist” (for which I believe a degree it’s necessary) as some graduates in shady boot camps expects to do. I’m just asking myself if I can teach myself enough IA to enrich personal projects in which IA makes sense and to become apre flexible professional.

TLDR: Opinions of area of interest between these subjects (specializations):
1 Algorithms
2 Programming languages
3 Business analytics
4 Pervasive computing

Hi, I'm about to choose specialisation of my software development masters. I'm almost certain what I'll go with (algorithms), but I wondered what other people thought and would choose if they had the opportunity. I'm still not too experienced in all of these areas, making the choice a bit hard :-)

After almost 3 years of professional experience I’d like to specialize more in something but I struggle to because I enjoy almost every aspect of IT: I find front-end really fun, I find very rewarding to build good user experiences and I’m excited for what WASM may bring on the table but I even like to work on the back end on both: legacy monoliths and modern micro services, I love to refactor clunky programs full of “cargo cult” code and redundancies put by people who doesn’t understand the framework they’re using and to make them shine. I’m even good at UNIX/Linux scripting and with Docker (often colleagues asks me advice on these topics) so I’m really tempted to upgrade my knowledge by learning K9S and reading the 1000+ pages of Unix Power Tools to get into operations/DevOps especially considering which the field is the least likely to be overrun by cheap developers coming from a 3 months boot camp.
On top of that I’ve got even into more theoretical topics: I’m following a course on algorithms and data structures in C and in future I want to learn the basics of AI for a personal project but these things aren’t much about employment but personal culture.
Have you got any advice for this disoriented young man?

They put me on a new project, asks me if I want to work with A and B technology, tell them I am not interested. Then partner talks me back feeling like he is pushing me. Tell them I still do not want to work with it and they need to find C technology which I have been very clear that I want to specialize in. I know they have lots of projects with C technology but they are doing things difficult for me. Do not want to be like a kid but I need to think about my future. Maybe I should suck it up or tell them goodbye and move on, anyone in similar situation?
