O'Reilly

FEBRUARY 18, 2020

It’s the single most popular programming language on O’Reilly, and it accounts for 10% of all usage. Growth is still strong for such a large topic, but usage slowed in 2018 (+13%) and cooled significantly in 2019, growing by just 7%. In programming, Python is preeminent. Still cloud-y, but with a possibility of migration.

However, they are scattered across multiple systems, and there isn’t an easy way to tie related messages together. You’re joining tables, resolving status types, cross-referencing data manually with other systems, and by the end of it all you ask yourself why? Things got hairy.

CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. Was there some other program consuming CPU, like a misbehaving Ubuntu service that wasn't in CentOS? There's no Java stack—there should be a tower of green Java methods—instead there's only a single green frame or two.

We had our first Studio applications consuming the federated graph, without any performance degradation, by the end of the 2019. This gives us access to Netflix’s Java ecosystem, while also giving us the robust language features such as coroutines for efficient parallel fetches, and an expressive type system with null safety.

HammerDB

JUNE 27, 2022

HammerDB has graphical and command line interfaces for the Windows and Linux operating systems. An important concept was to simulate database users called Virtual Users in parallel (rather than concurrently) to accurately simulate a real database workload with multiple users running from separate systems. Why HammerDB was developed.

The Morning Paper

SEPTEMBER 12, 2019

The Apache MADLib project is still going strong, and the recent (July 2019) 1.16 SQL provides a declarative programming interface, below which the system itself can figure out the most effective execution plans based on data size and statistics, layout, compute hardware etc. VLDB’19. Why would anyone want to do that???
