It’s Hacktoberfest again but this year maintainers drown in tsunami of pull-request spam, one could say it is hurting Open Source. If you want a good laugh or cry (or both), check out the tweets of @shitoberfest.
If you want to participate (I ecourage you, it’s fun), check out the updated rules since the organizers needed to change them because of the enormous amunt of spam.

Java InfoQ Trends Report (September 2020)
The article provides a summary of how the InfoQ editorial team currently sees the adoption of technologies and emerging trends within the Java space. They focus on Java the language, as well as related languages like Kotlin and Scala, Groovy, the Java Virtual Machine, and Java-based frameworks and utilities: Java InfoQ Trends Report (September 2020)
Thanks Gabor for the article. :)

Is High Quality Software Worth the Cost?
TL;DR: Of course, what did you think? :) Read the details in the article: Is High Quality Software Worth the Cost?.
- Neglecting internal quality leads to rapid build up of cruft
- This cruft slows down feature development
- Even a great team produces cruft, but by keeping internal quality high, is able to keep it under control
- High internal quality keeps cruft to a minimum, allowing a team to add features with less effort, time, and cost.
Sadly, software developers usually don’t do a good job of explaining this situation. Countless times I’ve talked to development teams who say “they (management) won’t let us write good quality code because it takes too long”. Developers often justify attention to quality by justifying through the need for proper professionalism. But this moralistic argument implies that this quality comes at a cost - dooming their argument. The annoying thing is that the resulting crufty code both makes developers' lives harder, and costs the customer money. When thinking about internal quality, I stress that we should only approach it as an economic argument. High internal quality reduces the cost of future features, meaning that putting the time into writing good code actually reduces cost.
This is why the question that heads this article misses the point. The “cost” of high internal quality software is negative. The usual trade-off between cost and quality, one that we are used to for most decisions in our life, does not make sense >with the internal quality of software. (It does for external quality, such as a carefully crafted user-experience.) Because the relationship between cost and internal quality is an unusual and counter-intuitive relationship, it’s usually hard to >absorb. But understanding it is critical to developing software at maximum efficiency.
