Blazor. I stopped doing development work about five years ago because JavaScript seemed to be taking over everything. I absolutely hate JavaScript so I ended up making a career change to not have to deal with it anymore. Blazor (and other compile to wasm frameworks) lets you avoid 90% or more of the JavaScript nonsense that makes up modern apps.

Do you hate JS the language or do you hate the ecosystem? JS gets a bad rap from folks that have never had a chance to master the language and do pure JS development, which is actually quite enjoyable.

Learn how to really use a relational database, relational data modeling, and SQL. Not knowing of their capabilities may lead you to unnecessarily complicating your tech stack. You can go a really long way with just this domain of expertise. From there, do the same with whatever key-value store interests you (for me, it's Redis). Python isn't known for high performance but when a django web app uses a cache and relati…

Do you have any examples of a good book that will take me from intermediate to advanced? Most of the guides I’ve found online either assume you’re an absolute beginner or already quite advanced. I’m quite competent with SQL and relational databases, but nearly all of my experience is on Microsoft SQL server. I’ve heard postgresql has a lot of really cool functionality but I would really love a nice, professional, in-depth book that will help me get fully up to speed.

Sorry if offensive or presumptuous, I assume you are max. 30 years old? Being a freelancer the last 5 years (previously doing webdev part-time for 15 years) and having a couple of long-term side projects, I've been "burnt" enough that I've gotten tired of chasing shiny tech, just for it to become abandoned (e.g. bower, grunt, AngularJS) or introduce big breaking changes (e.g. some upgrade paths in PHP's Laravel or Sy…

The irony of this post is saying you don't want to learn new and then saying you used parcel.

I didn't say to not learn new tech, but just don't go deep-diving into it because some people think it's cool.

Parcel was something small and minimal and got the job done for me. I'm not dismissing all shiny new tech. After it was released, I waited a year until I felt I should use it in a project.

I liked it because it was easy to use, fast, covers 99% of my use cases, and in case it got abandoned, it should be easy to replace.

> Sorry if offensive or presumptuous, I assume you are max. 30 years old? This line added absolutely no value to your comment (try reading your comment without the opening line and tell me it's any different) and resulted in a lot of distraction from the rest of the conversation. It's curious to me that you decided to include it even though, as indicated by the disclaimer you provide at the beginning, you knew its po…

I simply ignored the first line and appreciated the rest of the response because it had good actionable information. I wish I had older mentors in engineering and CS when I was 20-35yrs to tell me their war stories and point me to promising areas of work. This constant outrage at every perceived slight is a recent phenomenon of the Facebook/Twitter decade and it is suffocating.

> This constant outrage at every perceived slight is a recent phenomenon of the Facebook/Twitter decade and it is suffocating.

Frankly, the OP said something rude. It's not a "perceived slight". It was unnecessary, offensive, and presumptuous. Why shouldn't they be called out on their behavior? Congratulations on your ability to ignore the first sentence, but that doesn't excuse OP.

My first day of Postgres experience is that the first query to fetch 1 record takes 5 seconds and subsequent queries take 50ms. There are a 1000 explanations as to why, but I have no idea which is correct. I hate Postgres. I heard it does JSON or something well.

Really loved your course! Your Docker introduction inside that course was wonderful! Kudos!

Thanks a lot for the kind words, I really appreciate it. I'm looking forward to posting even more free updates this year.

Awesome! Will look forward to it!

In a word: biotech. Okay, yeah, that's a bit beyond the scope of your question... Tech-wise I think the stealth silver-bullet will be "Categorical" programming†. When this hits it might even contract the job market for programmers. Compiling to categories" Conal Elliott http://conal.net/papers/compiling-to-categories/ † As in a kind of PL paradigm: https://en.wikipedia.org/wiki/Programming_paradigm

Any good resources you have for beginners in biotech?

This is a great book, but it's not a book on SQL.
