I'm currently based in London, UK. I have a talent visa that allows to work without restriction, including consulting. Joined the company to build a distributed BFT database. In this role, I'm fully responsible for the product, its technica…
Over the last 20 years that I've been writing software, my ability to deliver projects has increased. I especially notice this in context of pet projects, that I not only finish, but also continue using over time. You may say that this is j…
The virtual machine I'm working on can now allocate and access arrays from the bytecode and assembly. Arrays are one of the basic data structures in the VM, in addition to numeric types and pointers. Until now, I was only able to operate wi…
Reraising errors/continuations caused me some serious head-scratching, but now it's complete. You can reraise errors from the guard handler, and the continuation will be reattached to the place where it's been taken from as if nothing has h…
I've been writing my programming language in pure C for quite some time, but recently I decided to port it to C++. The key problem that made me do so is error handling. While I was working on the bytecode virtual machine, it was all relativ…
It's time to admit that I've failed with a first iteration of my programming language. And the reason for that is mutability. I've set myself a goal to have independent virtual machines that can exchange serialized objects, but that turned
I've been using the Framework laptop for a few weeks now, and would like to share first impressions. In short – it's the best laptop I had in years. First, there are a few things that this device gets exactly right: screen, keyboard and tra…
I like tiling window managers. But sometimes I switch to Gnome for certain tasks. One of such cases is when I need to plug the laptop to TV to watch a movie. It can be hard to switch sound output to go through HDMI using just a pulseaudio c…
My previous post about speeding up the library search in Emacs was mostly a hack, but I think I have a more radical solution. So, the key problem with slow library loading in Emacs is that it does lots of separate syscalls for every module
I'm writing valeri to be a pure language. As a pure language, it needs a way to somehow do IO in a way that doesn't violate purity and doesn't lead to mutation of state or non-reproducible behavior. One of the ways to achieve this is called…
Latest changes to Valeri have introduced significant improvements to error reporting, not only within the parser, but also within the compiler. Where previously the compiler will error out with a cryptic "compilation error", it now explains…
I don't know why, but the ease of just calling one terminal command when I need to play some background music is so habit-forming, that I just haven't been doing it any other way. In particular, whenever I need electronic music for writing
