I can assure you that it's a very different crowd from what I see at my day job. We're very used to a being among a self-selected group where something like an EE degree is assumed. Physics/Math majors are not uncommon including some PhDs.
And I don't mean just credentials. It's noticeable in how intellectually curious people are, how they digest information, how comfortable they are with basic school level math (e.g. complex numbers). Not to mention that textbooks at that level are a little watered down in comparison with your first year college textbooks.
They do rely on something that sounds like a COBOL mainframe from 40 years ago to me. They see people making the same basic clerical mistakes every year when towns and government organizations report their numbers. Like literally not being able to format numbers according to certain rules on the first try and such. Sending excel file in emails is the level of automation they rely on. They are all union jobs.
She was recently preparing for an obscure accounting certification. There's very little publicly available information to use and at most one textbook. She was asking her LLM (Gemini?) to formulate exam-level questions instead and explain the answers. She told me it worked spectacularly well.
Secondly, in CA to be a real residential electrician you need to be C-10 licensed. Which requires all kinds of time consuming prerequisites to begin with. Some of them could be a challenge if you are not the kind of guy who knows a guy. Apprenticeships, unions, depending on your major 1 to 4 year of "hands-on, full-time journey-level experience" and such. Your best hope is probably that your EE degree from 20+ years ago still counts for something.
And there quite a few 20 yo candidates to compete with who are taking DC/AC circuits classes in community colleges this very moment. They are not spoiled with life-long office work experience.
The competition among people who'd like to be an industrial robotics technician at the Tesla Fremont Factory is very real too.
Contra: I'm reading digital circuits and introductory FPGA programming books this summer - fullstack development for the robotics dominated future here I come ;) Granted some EE classes in your old major will help. But modern digital circuits and embedded hardware space also have a lot of similarity to your muscle memory as a software developer.
Depending on how much memory is used by the Thread stack (presumably 1M-512K by default, allegedly 128K with Alpine base images) that's your 1G-500M heap space usage improvement right off the bat.
The migration from JDK17 to JDK21 was uneventful in production. The only issue is limited monitoring as a thread dump will not show most virtual threads and the micrometer metrics will not even collect the total number of active virtual threads. It's supposed to work better in JDK24.
The Spring Framework directly supports virtual threads with "spring.threads.virtual.enabled=true" but I haven't tried it to comment.
47 MPG on the highway (but it goes down dramatically when driving around town to ~35). My Limited trim has a glass cockpit with all the popular safety features. Its exterior also looks more expensive than it is and at the time was way cooler than Civic or Corolla.
It remains to be seen what happens around 100K miles/10 years though and how it compares to my previous Corolla experience.
