Ever since the Raspberry Pi was released in 2012, I’ve been fascinated with single board computers. As I have dived deeper into the Linux rabbit hole and the open source support for Raspberry Pi’s has grown they have transformed from interesting learning tools to highly functional every day devices.
Lets take a look at what my collection is currently being used for.

I finally managed to upgrade my PC, 5 years late (more on that later). Getting hold of parts has not been easy, but why has there been such a shortage of semiconductors?

I saw an idea for a nerdy gift on Reddit for your significant other. A word-cloud of conversations you have had. That seemed like a quick and easy idea for a anniversary card…
Now that I’m done, I can explain what a massive pain this turned out to be.

Since Covid hit last year, Zoom has become a verb for video chats. Some of their questionable security practices and their ties to China have made some people wary of using it.
Fortunately, if you didn’t want to install something you can always join from a browser, if you’re willing to give up the very useful Gallery view.

I am moving house soon, which means setting a sweet new home network. Exciting times!
Unfortunately the move was pushed back by a week, which is fine, except… hey what happened to the internet? Oooops.
What to do? A jankey interim solution obviously.

The single most useful thing you can do to help fight the Coronavirus is to follow advice on self-isolating, social distancing and washing your hands.
But there is also a more practical thing you can do, running distributed computing programs.

I found a website (k6.io) which allows you to load test websites and API’s using AWS. With a free account you can test from one location with 50 virtual units for up to 12 mins. Spinning up a load test of get requests, Cloudflare served up all the traffic no problem, leaving my minimal VPS web-server alone. Then I tried again with post requests and BAM… 100% CPU load, response time over 6 seconds.
What was happening? Shouldn’t Cloudflare stop things like this?

Naturally I procrastinated too much to write anything about EMF 2016, but since I’m going again in 2018 I though I’d write a little of what I remember for comparison later.
My friends had been to EMF 2014 and convinced me to go with them in 2016, and I’m really glad they did. It was an awesome 3 days!

After using the Raven theme for a while, because I like dark themes, I have gone back to the standard WordPress 2017 theme. Mostly because it had a dark option. It also doesn’t look terrible, which the Raven theme kind of did. Continue reading “Theme Changes and Optimization”
I’m back, not that I was ever here. A few weeks ago I noticed a large(ish) bill on my credit card statement for my web hosting. Oh, that’s right I though, I have a website. That one I made to write about my engineering/tech projects which I never update, not that I do any work on them anyway. Clearly, I had great foresight in choosing the name Procrastinating Engineer.
