Amazon RDS MySQL is a popular choice for running a MySQL database. When you provision an RDS MySQL instance, it comes pre-installed with Amazon's default configuration settings for dozens of tunable knobs. These knobs control the DBMS's runtime behavior (e.g., buffer pool policies, thread scheduling). Amazon's defau...

Now that RAD Studio 11 is out, I want to get back to some of its new features, starting with VCL enhancements. Among the new features in Delphi 11, C++ Builder 11 and RAD Studio 11 one area I'm very happy about is the work the team has done on core VCL components, addressing a number of requests that have been pendi...

The perlcritic tool is often your first defense against “awkward, hard to read, error-prone, or unconventional constructs in your code,” per its description. It’s part of a class of programs historically known as linters, so-called because like a clothes dryer machine’s lint trap, they “detect small...

C++ 17 has introduced the std::optional<T> template class that is analogous to the Maybe/Optional monad implementation in many other languages. “Analogous” is doing a lot of work in this statement because the C++ type checker is not going to help you avoid dereferencing an empty optional like Rust, Haskell, Scala, K...

There is no shortage of package managers. Each tool makes its own set of tradeoffs regarding speed, ease of use, customizability, and reproducibility. Guix occupies a sweet spot, providing reproducibility by design as pioneered by Nix, package customization à la Spack from the command line, the ability to create con...

Ruby, unlike Python, makes lots of things implicit, and there's a special kind of if expression that demonstrates this well. It's often referred to as an "inline-if" or "conditional modifier", and this special syntax is able to return one value when a condition is true, but another value (nil, specifically) when a c...

Perceus: Garbage Free Reference Counting with Reuse

We introduce Perceus, an algorithm for precise reference counting with reuse and specialization. Starting from a functional core language with explicit control-flow, Perceus emits precise reference counting instructions such that (cycle-free) programs are garbage free, where only live references are retained. This enables further optimizations, like reuse analysis that allows for guaranteed in-place updates at runtime. This in turn enables a novel programming paradigm...

Time to continue to explain what Arcan actually “is” on a higher level. Previous articles have invited the comparison to Xorg ( part1, part2 ). Another possibility would have been Plan9, but Xorg was also a better fit also for the next (and last) article in this series. To start with a grand statement: Arcan is a si...

Context The success of QuickCheck has led to the development of property-based testing (PBT) libraries for many languages and the process is getting increasing attention. However, unlike regular testing, PBT is not widespread in collegiate curricula. Furthermore, the value of PBT is not limited to software testing. The growing use of formal methods in industry, and the growth of software synthesis, all create demand...

A historical defect in the ifupdown suite has been the lack of proper supervision of processes run by the system in order to bring up and down interfaces. Specifically, it is possible in historical ifupdown for a process to hang forever, at which point the system will fail to finish configuring interfaces. As interf...
