What Makes an Application Scalable?

What Does a Scalable Application Mean? Applications that are depended on by thousands of users may see peaks or dips in demand during the day and managing the cost of running the infrastructure can be challenging. Scalable applications are applications that are able to increase their resources to serve requests as they come. What types of Scaling are there? There are two basic examples of scaling for applications, Vertical Scaling, where an application’s resources are increased due to demand, such as increasing the RAM available to an application host. Vertical Scaling is also sometimes referred to as scale-up. Horizontal Scaling,… Continue reading What Makes an Application Scalable?

What is a Software Supply Chain Attack?

Flashcard Club V0.0.3

Its been a good while now and Flashcard Club is well on its way to a functional product. There has been some progress on features, notably the inclusion of Google OAuth2 through Laravel Socialite. Logging in through your Google Account should greatly increase the speed of adoption for new users and improve retention and user acquisition. With that in mind, Flashcard Club has been online now for about 3 months and has yet to have a single user. I believe this is mostly due to myself not promoting the product which I will feel more comfortable doing once the site… Continue reading Flashcard Club V0.0.3

In the end I have settled on marked. Another area I am struggling to decide on is how best to… Continue reading Flashcard Club February

A new baby if you will, a commercial enterprise but one I own. I’ve been working full-time on Laravel projects and I want to improve my skills to really get better at it. Its a great framework after using raw PHP and template engines like handlebars. During this time I came to the realisation that I wasn’t totally stoked with… Continue reading I’m starting flashcard.club

Hull University Minecraft Map

I used geocraft to generate a Minecraft map of the University of Hull, and now I am sharing it with you. You can see a short video of the map below. The map is available as OpenStreetMap data only, or with the DEFRA (Department for Environment, Food & Rural Affairs) lidar data from, (I think) 2015, so the multi-story car-park is not included for example. The original project is broken as the lidar data did not get included, but it was possible to fix it using the suggested changes by RobinWhitfield here in this issue. The original licencing for this… Continue reading Hull University Minecraft Map
