`heed` and `heed3` are high-level wrappers of LMDB.

This post is dedicated to the memory of Niklaus Wirth, a computing pioneer who passed away January 1st. In 1995 he wrote an influential article called “A Plea for Lean Software”, and in what follows, I try to make the same case nearly 30 years later, updated for today’s computing horrors. The really short version: the way we build/ship software these days is mostly ridiculous, leading to 350MB packages that draw graphs, and simple products importing 1600 dependencies of unknown provenance.

★ Fastfull embedded transactional key-value storage engine ★ Surpasses the legendary LMDB in reliability, capabilities and performance ★ Used in hundreds of open source projects, including Ethereum...

In this blog post, we explore the enhancements needed for Meilisearch's document indexer. We'll discuss the current indexing engine, its drawbacks, and new techniques to optimize performance. With insights on parallel processing, memory management, and efficient data handling, we'll draft a robust new indexer to better handle large datasets and frequent updates. Join us for a deep dive into making Meilisearch's indexing faster, more efficient, and scalable.

Recently the Dutch Electoral Board (where I am also a very part time advisor) invited me to do a talk reflecting on their open source Abacus vote tabulation software. Much software is now provided as a service, and is typically deployed continuously (CD, continuous deployment), surrounded by enough automated testing (CI, continuous integration) that we can be reasonably sure that a new revision is likely to at least work to some extent.

One of the latest fashions in the Java world is GraalVM. For someone who has been around, I still remember the "Write once, run anywhere" slogan of Java virtual machine. Apparently, the wheel has spun back, now people want to write native code in Java, which has to be compiled …

In my previous post, Competing for the JOB with a Triplestore, I showed that a triple store, such as Datalevin, can compete with the best row stores on complex relational workloads. Since then, I have rewritten Datalevin's rule engine and improved its storage and query engine. This post focuses on …
