Blog posts

Blog post: Acorn Validator

Over the last week, I've been hard at work on an entry for #LOWREZJAM. While it's not finished yet (submission is on Thursday), I've found some time to write up a quick blog post about a particular aspect of it. Of course, I'll be blogging about the rest of it later once it's finished :D The history of my entry is somewhat.... complicated. Originally, I started work on it a few months back as an i… Read more →


Revolutionising CSS with Grids

(Source: The header of Mozilla's Firefox grid inspector landing page. Mozilla neither endorse this blog post nor probably know that it exists :P) You may or may not have heard about it by now, but browsers now have support for a new feature of CSS - the Grid. I'd argue that it's the single greatest addition to CSS since it was created, and to that end I wanted to post about it here. First though,… Read more →


Placeholder Image Generator

(Above: An example output with debugging turned on from my placeholder generation service) For a quite a considerable amount of time now, I've been running my own placeholder image generation service here at starbeamrainbowlabs.com - complete with etag generation and custom colour selection. Although it's somewhat of an Easter Egg, it's not actually that hard to find if you know what you're lookin… Read more →


Password Protect: Secure?

Everyone knows about passwords. Most people I've met usually react to creating a new account with a variety of negative reactions - mainly due to the annoying issue of having to create a new password (or even worse, re-use an old one!). Most people I've met also reuse at least one password several times, too! This is obviously a bad thing, but what can we do about it? Perhaps, while we're at it we… Read more →


Job Scheduling on Linux

Scheduling jobs to happen at a later time on a Linux based machine can be somewhat confusing. Confused by 5 4 8-10/4 6/4 * baffled by 5 */4 * * *? All will be revealed! cron Scheduling jobs on a Linux machine can be done in several ways. Let's start with cron - the primary program that orchestrates the whole proceeding. Its name comes from the Greek word Chronos, which means time. By filling in a… Read more →


Search Engine Optimisation: The curious question of efficiency

For one reason or another I found myself a few days ago inspecting the code behind Pepperminty Wiki's full-text search engine. What I found was interesting enough that I thought I'd blog about it. Forget about that kind of Search Engine Optimisation (the horrible click-baity kind - if there's enough interest I'll blog about my thoughts there too) and cue the appropriate music - we're going on a fi… Read more →


Demystifying Inverted Indexes

(The magnifying glass in the above banner came from openclipart) After writing the post that will be release after this one, I realised that I made a critical assumption that everyone knew what an inverted index was. Upon looking for an appropriate tutorial online, I couldn't find one that was close enough to what I did in Pepperminty Wiki, so I decided to write my own. First, some context. What's… Read more →


Redis in Review: First Impressions

(Above: The Redis logo backed by a voronoi diagram generated by my specially-upgraded voronoi diagram generator :D) I've known about Redis for a while now - but I've never gotten around to looking into it until now. A bit of background: I'm building a user management panel thingy for this project (yes, again. I'll be blogging about it for a bit more yet before it's ready). Since I want it to be a… Read more →


<code>#movingtogitlab</code>: What's up, Thoughts, and First Impressions

You've probably heard by now that GitHub has been bought by Microsoft. It was certainly huge news at the time! While I did tweet at the time (also here too), I've been waiting until I've gotten all of the repositories I've decided to move over to GitLab settled in before blogging about the experience and sharing my thoughts. While I've got some of them settled in (you can tell which ones I've done… Read more →


Routers: Essential, everywhere, and yet exasperatingly elusive

Now that I've finished my University work for the semester (though do have a few loose ends left to tie up), I've got some time on my hands to do a bunch of experimenting that I haven't had the time for earlier in the year. In this case, it been tracking down an HTTP router that I used a few years ago. I've experimented with a few now (find-my-way, micro-http-router, and rill) - but all of them fe… Read more →
