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 →


Achievement Get: Complete Degree!

I've just finish my degree at University this week. I'm still waiting on results, but I thought I'd make a post about it documenting my thoughts so far before I forget. Note that this doesn't mean the end o this blog - far from it! I'll be doing a masters this next academic year. It's been a great journey to have the chance to go on. I feel like I've improved in so many different ways having gone… Read more →


Just another day: More spam, more defences

When post is released I'll be in an exam, but I wanted to post again about the perfectly fascinating spam situation here on my blog. I've blogged about fending off spam on here before (exhibits a, b, c), but I find the problem is detecting it in a transparent manner that you as the reader don't notice very interesting, so I think I'll write another post on the subject. I could use a service like G… Read more →


Shift-Reduce Parser Part 2: Building Furniture (1)

Hello and welcome! I got a bit distracted by other things as you can tell, but I'm back with part 2 of my series on building a shift-reduce parser. If you're not sure what I'm talking about, then I'd advise reading part 1 first and then coming back here. It might be a good idea to re-read it anyway, juts to refresh your memory :-) Last time, we created some data classes to store the various rules… Read more →


Distributing work with Node.js

(Above: A pair of graphs generated with gnuplot from the data I crunched with the scripts I talk about in this blog post. Anti-aliased version - easier to pick details out [928.1 KiB]) I really like Node.js. For those not in the know, it's basically Javascript for servers - and it's brilliant at networking. Like really really good. Like C♯-beating good. Anyway, last week I had a 2-layer neural net… Read more →


AT24C64 EEPROM and the Arduino

For a project of mine I've bought a bunch of parts. One of those are a bunch of AT24C64 EEPROM chips - which are basically really small SD cards which, in this case, can store 64 KiB of data - even when the power is switched off, as you'd expect. I ended up having a bit of trouble getting it to work though, as the Arduino IDE appears to have been abandoned and I don't think it's still in developme… Read more →


Deep Sleep on ESP-Based Chips

If you're interested in the Arduino ecosystem, you've no doubt come across the Wemos family of boards. Basedon the ESP8266, they have WiFi and TCP / UDP support built in! While that's very cool indeed for such a low-power device, in this post I'll be focusing on another cool aspect of the chipset, as I'm going to need to for a project in the nearish future (which I might blog about too!). Curiousl… Read more →


Representing clickable links with awkward characters in LaTeX

Hello again! As this Semester draws to a close, I thought I'd make a quick post about links in references in LaTeX. I've discovered recently with the help of a lecturer (thank you!) how properly represent links in LaTeX references - as I've been having some issues with getting the ones with underscores _ and tildes ~ displaying correctly. For example, if I wanted to cite the Vulkan specification,… Read more →
