Why? On the one hand, to further my Python learning and explore AWS DynamoDB. On the other hand, because I ultimately would like to provide some context to me in the game which is not present natively. By focusing on visualising a subset of the available events, I gain a foothold in parsing the game data into a database and putting an API in front of it. https://ja.mesmontgomery.co.uk/2019/05/producing-live-visuals-from-a-powershell-rest-api/ Fri, 17 May 2019 00:00:00 +0000 https://ja.mesmontgomery.co.uk/2019/05/producing-live-visuals-from-a-powershell-rest-api/ TL; DR In this post, I’d like to share an example of bringing to life the data returned by an API. One PowerShell example takes the output of Get-NetTCPConnection and Get-Process to create a JSON representation of process IDs and their network connections. Universal Dashboard provides the means to expose this via REST API. Lastly, the vis.js network module creates a visual representation of this data. Here is an example video: https://ja.mesmontgomery.co.uk/2019/04/visualising-your-dns-cache-with-psgraph/ Fri, 26 Apr 2019 00:00:00 +0000 https://ja.mesmontgomery.co.uk/2019/04/visualising-your-dns-cache-with-psgraph/ TL; DR In this post, I’d like to introduce you to how I’ve used PSGraph to create visuals from code. I’ll show you how to represent the Windows DNS cache graphically. Here is an example output (click for a full size image): Below I cover how to arrive at that outcome. You can find all scripts used at my GitHub page. Why DNS The hierarchical nature of DNS (subdomain.topleveldomain.rootdomain) lends itself to graphing. https://ja.mesmontgomery.co.uk/2019/04/a-punnet-of-raspberries-with-a-side-of-visuals/ Sat, 06 Apr 2019 00:00:00 +0000 https://ja.mesmontgomery.co.uk/2019/04/a-punnet-of-raspberries-with-a-side-of-visuals/ TL; DR I finally dusted off that Raspberry Pi in the corner. Initially, I was putting Pi-hole through its paces. One thing led to another as a new rabbit hole emerged in the form of adding encrypted transport to forwarded queries (a subject I visited in the past). I purchased another Pi for resiliency. I then explored how I might visualise the performance of the solution. Lastly, a first for me, I have shared this code on my GitHub page.
