Just shy of two months ago, I published I shall toil at a reduced volume, which addressed the fact that I’m not getting what I want from my blog anymore, and I would be taking an indefinite break. Well, I am ready to resume my writing, albeit with a different tone and focus than before. Well, that w...

Unless work is done per architecture to implement HAVE_ARCH_VMAP_STACK / CONFIG_VMAP_STACK, the Linux kernel defaults to two pages worth of stack per thread. Note: on many contemporary systems the page size is 4KiB, but this is actually configurable for many architectures. The trade offs probably re...

One of MySQL 8’s biggest improvements is the support of window functions. As I always said in conferences, there’s SQL before window functions and SQL after window functions. Once you start using them, you’ll use them everywhere. Some of you poor souls are unfortunate enough to be stuck on MySQL 5.7...

My previous blog seemed only to continue the confusion regarding classes in Functional Programming. Indeed, many people got quite irate. So perhaps a bit of code will help. Trigger Warning: Object Oriented Terminology. Dynamically Typed Language. Mixed Metaphors. Distracting Animations. To all the a...

Previously on this blog, I’ve written a post explaining why you should use jOOQ’s code generator, despite the possibility of using jOOQ without it. In a similar fashion, as I’ve answered numerous jOOQ questions on Stack Overflow, where someone used jOOQ to build a query, but then executed it elsewhe...

I do most of my text editing with MacVim, but when I pair with people I like to use tmate. tmate is just an easy way to connect tmux sessions with a remote person. But this means that I go from coding in a GUI to coding in a terminal. Normally this wouldn’t be a problem, but I had made a Fish alias ...

I recently tweeted the following: Should you subdivide a functional program into classes the way you would an object oriented program?Yes. You should. Because the rules don’t change just because you’ve chosen to use immutable data structures.— Uncle Bob Martin (@unclebobmartin) January 17, 2023 This...

For the next part in my Bean Machine retrospective to make sense I’ll need to make a short digression. In looking back on the almost 20 years I’ve been blogging, it is surprising to me that I’ve only briefly alluded … Continue reading →

Maxime (Senior Staff Engineer and leader of the YJIT project) shares the updates that have been made in this newest version of YJIT, and fut...

jOOQ already has a LoggingConnection (see also the manual), which acts as a JDBC proxy Connection to log all SQL statements that are executed by any JDBC client (including Hibernate, MyBatis, JdbcTemplate, native JDBC, etc.). Starting from jOOQ 3.18.0, 3.17.7, and 3.16.13, a LoggingConnection is now...
