Unrelated to the real topic at hand: I find telling that an antiquated software company is choosing to publish stuff as PDF. I usually refuse to open such links - my personal choice of course - because I can't see any valid reason to use it in this context. Yeah PDF for printed forms, but anything else makes no sense to me, yet it's way more used that I could imagine.

PDFs are a great file format for digitally viewing print-style publications. This document appears to be in the style of a print publication, not a web page. Here's an example of two far less antiquated technology companies using a PDF for something that could also have been a web page, but was found to make more sense as a print-style publication: https://blog.google/documents/73/Exposure_Notification_-_FAQ...

Boy did that document header logo send a chill down my spine at the thought of the ultimate mega-merger of consumer tech.

It's really interesting to think about what computing projects look like over timescales that are not normally encountered in the industry.

It's rare for any software to achieve a kind of stable sustainability that allows it to continue development for as long as 25 years.

It gives me hope for some of the big open source projects - hope that maybe, eventually, all the bugs will be fixed - even if it takes decades.

Java might be the most successful programming language. It is a solid choice among many different fields. It is used on huge infrastructure projects (Apache Foundation), governments, big tech companies such as amazon, ibm, google, apple for many large scale services. It can do web, ml, GUIs, it's still strong among academics. On top of that it offers a great programming experience with excellent IDE support and it's…

In my opinion, Java as a web language is good when you don't need to really understand what's happening (like in low-traffic situations). If concurrency isn't an issue, then the massive amount of libraries can help you a lot. In high-traffic environments, that ignorance punishes you. I've always felt Java and the JVM are of the mindset that you need a Ph.D. to even understand how it works or how to configure it, and…

I work on a lot of legacy systems in financial services, the biggest issues related to threads is variable scope regarding servlet design patterns. I just migrated a 18 year old app off Weblogic to TomEE and we had issues with struts tags. The main app I work on has around 350 concurrent users. I have JMX on all the time and monitor it for long running threads and tune it when needed. The problem I have with Java is the massive amount of libraries that can be used and developers who copy and paste code and don't think about what the code does. The verbosity kills me too, it's so over done. I've decided to learn Go just because I'm tired of reading Java code, especially legacy code. But yes you are correct there is a lot of settings in the JVM and a lot to read to understand it. It's a powerful language with a lot of features.

I'm surprised that GraalVM is not mentioned. I have strong suspicions that Oracle is lining up Graal to become the next default JVM, after watching some talks from core developers describing how fragile the Hotspot codebase has become. Graal would be a good way to encourage ML, given it has language support for Python. Perhaps Graal is just not ready for Oracle to show all of their cards at this point. Or perhaps my…

> I'm surprised that GraalVM is not mentioned.

Java and GraalVM come from two different parts of the company. They're aren't done by the same people.

Spring Boot has historically been resource-hungry, but that's changing quite quickly.

Modulo usual caveats about not promising anything and safe harbours and forward-looking statements, VMware is interested in Spring efficiency up to a very high level in the org chart. Watch this space.

Disclosure: I work for VMware.

Personal anecdote: I am currently on the job hunt and literally every single position that requires Java also requires experience with Spring (Boot).

It might not be the trendiest, but it's definitely the most popular (as in "in demand").

Other than Effective Java, I recommend looking at some of the Google libraries, specifically Guava [1] and Guice [2] for dependency injection. Java is fundamentally a slow adopter of new techniques (it just got lambdas in JDK 8), but a lot of the Google libraries fill in the gaps. Note that if you are learning Java for Android development, that's a whole different sub-discipline. In that case I recommend the Android…

JDK 8 was released march 2014, so "just got lambdas" should be read as over 6 years ago...

Yeah, it is up to JDK 15 now

My comment is sexist, but culturally relevant from where I'm from.

Java is like your old wife/husband/spouse. It's not sexy, you probably don't enjoy much when doing things with it. But it's dependable and reliable, And, aren't you where you are now thanks to it?

Newer languages.. yeah they're sexier, more fun to play with, make people think you're cool when with them, but they might end up wasting your time :)

> (it just got lambdas in JDK 8) Interesting use of the word 'just'. At the risk of making readers feel old... Java 8 was released _6 and a half years ago_.

Maybe as a point of comparison (I wondered): C# got them in C# 3.0 in 2007.
