I am looking to learn more about 3d printing and how to create things for my place. I also would like to learn a little about Unity 3d programming.

I am curious what skill you want to learn in the coming year?




Starting already this month:

Digital painting and drawing. I'm already not bad at that, but I want my skills to be semi-professional at least. I have a very vivid imagination, and I want to be able to recreate the concept I see in my mind.

Computer science foundation. Right now, I'm at the stage that I know enough to explain them in layman terms, but not enough to actually participate in an active discussion or projects that rely heavily on academic knowledge. Stuff like compilers and interpreters, computer architecture, database systems, distributed systems, and OS architecture.

Another item on my list is reflecting more about philosophical and psychological matters (I read more fiction books than non-fiction ones at a ratio of 25:1, the only bibliography I've read was about George Lucas).


OMG ME TOO!!!


I want to get some basic woodworking skills together. I can do simple household plumbing, and I'm not going anywhere near electricity or roofing, but I would love to be able to patch up that corner of the staircase and have it look decent.


It sounds like you are trying to filter out unsafe hobbies?

Electricity can be done carefully and safely - just know your limits. I'd recommend at least getting comfy replacing outlets and switches. If you want to go one step further, light fixtures are also not too bad. Basically, anything where you just disconnect one widget from between two wires, and replace it with a different widget is fair game for most people. I call someone if I need new wires run or need to touch the main panels, though.

Likewise, woodworking is not as safe as most people think. Saws can bite you, as can drills, routers, etc... even rough edges on wood, or flying chunks of wood when you are teaching your 14 year old son to build a workbench and he just stands up a piece of wood next to your head and starts up a hand-held belt sander on it without clamping it.

The point being that tools that use electricity can be just as dangerous as the wires that carry the current, so plan accordingly.


I had my hand sucked into a router over the summer. I was really lucky, and now I understand what went wrong (it was a conventional cut, but I relaxed my hold and the bit pulled it into a climb cut. The wood got wedged between the bit and a fence and exploded, pulling my left middle finger in in the process). I'm as healed as I'll ever be and my finger looks normal, but I have no feeling in it, and effectively no fingerprint. That was a fun ER visit.


You might want to look up carpentry, instead of woodworking. They're actually pretty different in skills and approach.

It's like, with woodworking, step one is often "make everything perfectly square". In carpentry, nothing will ever be square. So you just have pretty different problems to solve


Man I would love to really get into either, but I have a 9-6 in the Bay Area and the one "workshop" weekend class I took was about tool use. It's really difficult to get into anything in a serious way, but any tips about somewhere in the Bay that really gets you into "carpentry" or into "woodworking" on weekends would be excellent!


I think of carpentry more like building a deck or a shed and woodworking is more of building a bench or a bookcase.

Even with woodworking things end up not square and fixing/hiding those mistakes is part of the project, just using a smaller scale than carpentry.


In construction contracting, an 1/8-1/4" tolerance is sufficient depending on the scale involved. With fine joinery, I typically find myself in the 1/32-1/16" range.


How to use a Mac. I've always been on Windows and used Linux VMs or WSL. I think it's time to take the plunge though.

Just got one recently. The difference between keyboard combos for text selection and navigation, and window switching is annoying so far, but I'm confident I'll get used to it.


For your sanity, I suggest you get the free open source app called Rectangle. Makes managing window splits and the like much nicer.


Agree. With no surprise, managing windows is Windows’ strong suit, and macOS really sucks at it. Rectangle makes it a lot more bearable.


Tell me about it, man… guess where the „@„ sign on the German keyboard is? On „q“. Guess how often I’m closing applications when I want to type an „@„ haha. Outside of that I think it got a lot better though.


You can use https://karabiner-elements.pqrs.org/ to change that. It would either require writing your own complex modification, or maybe it's already somewhere in their public repo https://ke-complex-modifications.pqrs.org/?q=german

Other solution would be to use something like Keyboard Maestro.


Classical double bass bowing technique - I'm looking to diversify from primarily being a jazz player due to scarcity of jazz gigs. I'm now actively looking for a teacher to start asap in the New Year.


I want to learn some low-level programming and hardware stuff, however, I don't really know where to start - sure, I can order an arduino with some kit, but I don't know much about electrical engineering, so making anything harder when a blinking LED will be a challenge.


i would suggest to follow Ben Eater's 8 bit computer https://www.youtube.com/watch?v=LnzuMJLZRdU&list=PLowKtXNTBy... and would strongly recommend to build it (you can see the parts on his website https://eater.net/ or buy the whole kit)


I’ll finally dig into frontend frameworks like react. I’m an old fart (started as C dev) and assumed it was a fad years ago - even thought no JavaScript was the future.

Silly me, now I have to play catch-up.


You're fine. C will always be around, and there will always be a need for C people.


Manually spin up and manage a meaningful local Spark cluster (say at least 1 master node with 8+GB and 3 worker nodes with 4+GB memory), build a data pipeline (don't care to much about the analytic things, I'm more into parsing tons of JSONs) and parse a meaningful number of JSONs (say 10GB at least) and optimize the parsing algorithm.

Low level computing. I purchased a kit and prepared to register a coursera embedded class. I also want to learn Windows system programming especially those related to Malware analysis (How does VM in OS work? What does a process contain? How to hijack a process? How to write shellcodes? These kinds of things).

Cold war politics and military-intelligence history. I got attracted to this field years ago after watching Godfather 3 and searched a bit about the background story. I know a few buzzwords but don't really have the $$, language capacity and time to drill deeper.

Mainframe. I didn't manage to register the IBM event this year, so it has to wait until 2022.

Sigh, too much to learn and too few time.


VR/AR dev. The idea of creating your own immersive universe sounds fun.


It's fun but very difficult. I never managed to do anything very useful but I would recommend it. Dealing with user interfaces in VR/AR makes web development feel a lot easier.


It's not particularly difficult with the help of Unity. Building complex things is difficult, but that's always the case.


I'm taking classes to be an EMT. I've taken BLS, but twice I've been in situations where I've felt completely helpless while someone is injured, and I want a set of skills where I can do something while waiting for an ambulance to arrive.


Writing. Mainly fiction writing and publish something on wattpad or similar platform.


Same here. Let's do this brother/sister!


I want to get better at playing music with other people. I've played a little guitar with friends, and want to be better at accompanying them. Also, I got a harmonica, for times I'm not able to carry a guitar.


Lmk if you want virtual lessons - we can set something up. I have been playing for over 10 years and have taught many people before


Sure, that would be fun! Thanks!


My iPad Mini got me to draw again. I want to get good at it. It's a relaxing hobby that forces you to pay attention to your subject.

I want to improve my German. I made a lot of progress in 2020. It emboldened me to be more extroverted, and to try things that were once out of reach due to the language barrier. I'll keep going.

I want to become more handy. I realised now that volunteering for a halfway house might be an excellent way to do it. I don't want to just be good with computers.


> I am looking to learn more about 3d printing and how to create things for my place. I also would like to learn a little about Unity 3d programming.

That made me smile because I got really interested on those a little ago.

Also recently improved my skills on:

- Linux, the command-line and bash

- Decompiling APKs into smali to understand some "unpublished" algos ;)

- Web authentication bypassing by editing/cracking cookies

- Customizing exported SQL code to restructure a database

Next in my list:

- Generating custom G-Code

- Surface-mount devices without heat

- Going deeper into web scraping and automation

- Philosophy of math


Not sure if it counts as a skill but I want to be able to run a half marathon. To word it towards the question, I want to pick up the skill of distance running


I did it early this year, finished on April 15th. I was not an avid runner by any means, onlyed picked up running around Sept 2020, started from daily walking only. You can absolutely do that, and it will feel awesome after you achieved it


Got into running during my sober October, I suggest you start with the COUCH25K program so you build a solid foundation.


How to get a decent rating without burning out, how to make it to the next level, and how to make tons of money.


You need a two pronged attack: Make more, spend less. Check out Dave Ramsey if you haven't already.

Rome wasn't built in a day, start very small, and tell yourself your doing GREAT every time you make or save a few extra dollars, even if it's just a few cents.

Write down your "WHY". Remind yourself multiple times throughout the day why you want more money.

Remember: Money can be made or spent, Time can only be spent.

Good Luck Friend!


What is a rating


Performance rating


It probably won't affect your income much, at least not relative to the effort you put into it.


You need a good rating for promotions and bonuses (at my company).


You only get to ask once a year, and they can deny it to you for any number of reasons. Bad economy, hiring freeze yada yada.

In the end you often work really hard for a disproportionately small payoff. I've seen many people waste precious time chasing unsatisfying promotions.

It's easier to spend that time looking elsewhere.


I’m planning to retire from contracting and looking for a permanent position where I can ideally

- dig into one of the specialisations I’d like to focus on: data processing frameworks, databases, computational geometry,

- keep improving my communication and mentoring skills.


C++. I've dabbled in C and old C++ since I've started programming, but I've never really felt like I learnt the language. I'm thinking of going though Meyers' most recent ed. of Effective Modern C++.


Not a new talent, but one I’d like to expand is painting with watercolor.

I’m considering learning Rust, but that will depend on bandwidth among/relevance to a zillion different side project interests.


1. Digital art. 2. Japanesse language. 3. Some Technical, Management skills. 4. Money making? Yes this one is what I need the most.

I want to learn Kubernetes and get the CKAD certification.

After years of using Marathon my company made the switch to K8s and I’d like to get into it properly.


Going to be brushing up on c++ and game development. 2022 is going to finally be the year in which I seriously make a game.


I want to achieve two things (besides work and fitness): study math fundamentals and get into (computational) neuroscience.


Beekeeping. I'm finally at the place financially where it won't matter if I lose my hives the first winter.


How to get better at technical interviewing, this is a skill that has cost me the most in terms of opportunity cost.


How to design programming languages


https://github.com/langjam/langjam This is a programming language development hackathon that is happening in December.


I want to move beyond only messing with Docker Compose and learn k8s.

Also want to learn how WASM works.


Being decent at Java, the first programming language i am currently learning :)


check out kotlin


The internet is always there to sidetrack you once you pick a direction. Learn Java. Build something. Kotlin will always be there and you will have a greater appreciation for it.


I'd like to make my first Morse Code contact on the HF bands.


Elixir/Phoenix


what is the motivation?


uh, I love Rails, and I get even paid to code with it :) :)

and so many says it's even better then Rails.

I do really wish to write code that is used by millions (super fast and easily scalable) and not just a small teams of engineers (I write mainly backends for my clients/contracts)

Then it is something new: I am so glad I moved to Rails many years ago (10), and now it's the first time I'm tented .... :)


Best of luck!


(more) Political Philosophy & Science :-)


cooking i know how to make good noodles and its been serving me well but i gotta try making something new for once


Unlearn k8s. Get better at Ansible.


That’s a fun one. Is that related to the « I can’t count that low » saying that would make you use k8s everywhere?


Portraits. And Jax I guess


Fly FPV drone


- Advanced Python.

- Docker.

- Spark.

- Common lisp/ Closure


sailing


GREAT!

my 2 cents:

the earlier the better; don't wait retirement.


skiing, maybe driving


problem discovery


public speaking

writing

timeboxing
