dreamrealsparcle is a SPARC-based portable workstation produced by Tadpole Computer. It was basically a Sun E150 squeezed into a laptop form factor, with an UltraSPARC CPU.
dreamrealjini is <reply>JINI was a Java-based distributed services framework. It allowed devices and software services to discover and join networks dynamically without manual configuration, predating modern IoT and modern service discovery patterns. Now dead and gone, replaced by REST and a lot of other easier-to-understand technologies.
dreamrealjavaspaces is <reply>JavaSpaces was a distributed storage/invocation API for JINI. It was typically implemented as an IMDG, and survives today in that role for a *very* few high-performing products. Implementations tended to improve upon the basic specs quite a bit as the specification was rather paltry.

dreamrealimdg is <reply>IMDG stands for "In-Memory Data Grid," usually a memory-based map, often distributable. Implementations center around the JCache API (JSR 107) or JavaSpaces, typically. Tend to be memory-hungry and incredibly fast.
dreamrealinfinispan is <reply>Infinispan is Red Hat's open-source IMDG, JCache/JSR-107 compliant, and doubles as Hibernate's distributed second-level cache.
dreamrealterracotta is <reply>Terracotta started as a JVM clustering tool (with notoriously clever bytecode instrumentation) before pivoting to distributed caching. Now effectively the server component behind Ehcache, owned by Software AG. The clustering roots are mostly historical at this point.

dreamrealignite is <reply>Apache Ignite is an open-source distributed database, cache, and compute platform from GridGain. Supports SQL queries and ACID transactions across the grid.
dreamrealcoherence is <reply>Oracle Coherence is the commercial benchmark for IMDGs — extremely fast, extremely expensive, and the thing everyone else measures themselves against. Common in high-end financial systems where latency is money and the licensing bill is someone else's problem.
dreamrealgigaspaces is <reply>GigaSpaces is one of the few surviving JavaSpaces implementations, extended well beyond the original spec into a full in-memory computing platform (XAP). Heavy in financial services, where the JavaSpaces model of tuple-space distributed computing still makes sense at scale. Fantastic product.
dreamrealblitz is <reply>Blitz was an open-source JavaSpaces implementation by Dan Creswell — the first Jini 2.x compliant JavaSpace available under an open-source license. Distinguished itself from Sun's reference implementation (Outrigger) by supporting tunable persistence via Berkeley DB, smart indexing, and embeddable mode. Long inactive.

dreamrealvalhalla is <reply>Valhalla is a Java project to augment the object model with "value objects," combining the abstractions of object-oriented programming with the performance characteristics of primitives. Has been worked on for a looong time, but is potentially a *massive* win for Java.
