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?
I Recovered my data from AWS S3 and all I got was this lousy bill.
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
It’s been a little while since the 25th of December when I decided to go public with this idea, a great deal of work has gone into flashcard club. Exactly 40 hours has now been dedicated to the project outside my normal 8:30-5. It’s been quite slow going in some aspects, one particular problem is the markdown library options are numerus and vary in completion and schema that make it hard to choose one that is appropriate for this project. 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
Hello everyone, I’m sure there is not many of you but I had to tell someone. As of the last few days I’ve really felt the need to get involved in something that is really what I am all about. 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
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
I recently have been working on a weather recording project and as part of this endeavour wanted to check that all of the variables I have posted to my API were set, it can be rather a lot of work to have to specify each if (!isset($_GET)) parameter so I decided to use a function that can take any number of arguments using a ‘variadic’ function in PHP. Now, when I want to use a new api ‘command’, I can simply do the following, This way, so long as we have specified the command and the variables required we can… Continue reading Check all API variables are included in a REST API for PHP.
Hello again, this is the second in a series of my home network posts. In this edition, we’re going to be flashing another router with OpenWrt. You can read part one here. I decided it was time to leave all the old hardware behind and move to brand new stuff. I was having problems with the ZYXEL VMG8924-B10A as the main router, it kept cutting out and was causing short minute outages that ultimately I think was due to the system running out of ram and botnets trying to break into the thing. So I decided it was time to… Continue reading My Home Network – Part 2
Because my time at university is ending I thought it best to archive the canvas pages available to me for later reference should I not be able to access canvas later if they change platforms or disable my account. I should probably add this is for archival purposes and I will not be able to share the data I was able to collect. Thankfully I was able to get the whole thing going in a few minutes and downloading took a lot longer. The first snippet I got from here, didn’t complete the first time, it seemed some image was… Continue reading Scraping Canvas (LMS)
I thought its time I put my GNUCash Data to good use and worked out how much I spent on fuel. I loaded up a simple Cash Flow bar chart in GNUCash and selected my expenses column for Car>Petrol and voila. If you are astute you may have also noticed there are additional ‘fixed’ (varies annually/monthly) costs to running a car such as tax, insurance, maintenance and depreciation but I have chosen to eliminate these costs because I would like to explore the benefits of buying another car. We can use this graph based on the last 3 years to… Continue reading How Much Does My Car Cost Per Mile?
