OrlandoJUG Reading List ::: from JavaSpecialists

Issue 305 - Contributing BigInteger.parallelMultiply() to OpenJDK

BigInteger has clever algorithms for multiplying large numbers. Unfortunately multiply() is single-threaded. Until now. In this newsletter I describe how the new parallelMultiply() method works and also how we can all contribute to the OpenJDK.

Issue 304 - ObjectInputFilter

JEP 290 introduced the ObjectInputFilter, which we can use to filter objects returned from an ObjectInputStream. We examine three ways of making filters, through subclassing, with factory methods and with text patterns, and then show some interesting edge cases.

Issue 303 - Null Keys and Values in Maps

Some Map implementations allow null keys and values. This leads to funky behaviour when calling putIfAbsent() and the compute functions. In this newsletter we look a bit more closely at the issues at hand when allowing nulls in maps.

Issue 302 - Virtual Thread Deadlocks

Virtual threads can deadlock, just like platform threads. Depending on what state they are in, this might be quite challenging to analyze. In this newsletter we explore some tricks on how to find and solve them.

Issue 301 - Gazillion Virtual Threads

As from this month, Project Loom is part of the mainstream OpenJDK as a preview feature. Expect fantastical results, as bloggers around the world kick the tyres of this fantastic technology. In this newsletter we show how we can have over 36 billion parked virtual threads in just 4 gigabytes of memory!

Recap of AWS re:Invent 2022

After a virtual-only event in 2020 and a reduced-size 2021 edition, re:Invent was back last week in Las Vegas with over 50000 attendees for the 11th edition. During multiple sessions and keynotes at the largest AWS yearly conference, the cloud provider announced new services and features, with the focus more on business solutions and data options than new building blocks.

Article: Adopting Low Code/No Code: Six Fitnesses to Look For

When selecting a no-code/low-code platform, six key fitnesses should be examined: purpose fit, cost fit, ops fit, user fit, use-case fit, and organization fit. The IT team should be heavily involved in this decision as they play a pivotal role in helping citizen developers with platform adoption.
