PHP and Wordpress Had to start over at the bottom after alcohol addiction destroyed me. Landed a job working with WordPress and started having quite a bit of with it. Naturally I just HAD to start tinkering and learned PHP to write plugins and manipulate the hell out of it. PHP isn't all that bad and is actually pretty easy to pick up. My only gripe with it is that quite a bit of the libraries aren't on par with othe…

Take a look at symfony

I learned a ton in 2018 after many years of working primarily with Java & Spring in large "enterprise" systems. It had been getting boring to the point of questioning if development is what I wanted to do. 2018 was a year of stoking the flames and I'm really enjoying hands-on technical work again.

I decided to pick up Python and learned some Flask & Django while I was at it. Really liking it. I also took some machine learning courses and wrote an image recognition app w Pytorch. I started & finished two Udacity nanodegrees to help keep me on task with learning these tools.

I worked for a while on a cloud infrastructure team and enjoyed learning a decent bit of Go, AWS & Terraform. Also touched on Docker, K8s & that whole ridiculous devops ecosystem.

Lastly, for the first time in my career, I worked solely in Linux (used to work solely in Windows). Never going back to Windows!

i guess its really rare for me to get to know a technology really well.

Most of the time I dabble in stuff up to the point when I am fluent enough to solve problems for fun and profit. But its really rare that I can really say that I actually really learned a technology to great depth.

Not sure that I managed to do that this year.

Databases and Streaming Systems. Apache Beam/Cloud Dataflow. GCP Data Stack: BigQuery, Spanner, PubSub. Moar Apache Kafka.

LOTS of SQL. Writing sophisticated queries, building a mental model of what a DB will try to do, doing perf evaluation by looking at query plans, Analytic/Window functions.

DB optimizations. Especially BigQuery and Postgres.

Non-trivial Java 8.

Holidays are for Rust, advanced Streaming systems, and Docker/K8 :-)

Will also be looking to get deep into the Python AI/ML ecosystem in 2019. I'm fairly adept in Python and thankfully the ecosystem for Data Science/ML is quite mature.

dApps! I did a lot of research on IPFS and was really excited to build my own dApp: Truth Ledger. It was also my first time using React, node.js, and npm. There are a lot of new tutorials out there if you're interested in getting started.

Truth Ledger uses React and Bootstrap for front-end and is "serverless" on IPFS. The user submits news article links which then have their meta-data uploaded to IPFS. If they're logged into MetaMask, it will record the IPFS hash of the data (as plaintext) to the Ethereum Testnet with an Ethereum contract.

I'd like to try out OrbitDB to make it more robust and skip some of the IPNS hash translation work. Eventually, with a series of smart contacts, my partner and I hope to expand the dApp to become a completely autonomous DAO (digital autonomous organization) for arbitrating truth. This would allow users to receive a truthiness score for the article link they submit.

Also had a lot of fun learning about wireless protocols and modulation. I followed some tutorials to build an antenna and intercept images from NOAA 15/18/19 weather satellites with a software-defined radio (SDR) dongle!

Also Unity and some WebGL! :D

Did a lot of learning in 2018. Finally moved away from Wordpress as a back-end, which I pushed to the limit. Learned Laravel and greatly improved my skills in vanilla PHP. Moved from jQuery to Vue.js - it's now my default front-end framework. Started using CLI and Git regularly. Learned PWA, service workers, serverless, Web3, some Solidity, more MySQL, server admin, scaling. Throughout 2018 I was coding all the time…

Thanks for sharing. I have a very basic question. What is your favoured method of learning new technologies/languages, how do you make the most of your time and make it stick? I am coming from a different background and the learning is a completely different dynamic to what I am used to. I could ask this of most here but you seem to be particularly proficient at learning loads in a short space of time.

Earlier quoted context omitted.

When you say you enrolled in 10-601, what did you do? I assume you aren't actually a student at CMU.

I'm a staff member at CMU, and so have the benefit of being able to enroll in classes for free.

I'm also a CMU staff member and I audited 10-601 this past semester but had to stop halfway through because it was too over my head, props to you for doing well in it!

Dialogflow and Node.js.

I needed them for my senior project[0] in college where I tried to make a lab assistant with the Google Home that would answer questions about the cafeteria menu and course information.

I learned a lot about webscraping which I had to do since I had no API to work with. I really wish I was more diligent in finishing it since prior really liked my demo.
