Detecting digit combinations in a number with PowerShell

How do you pass the time on a car journey? Most of us have memories of “I spy” or other game.

Lately, I’ve been looking out for number combinations after a car I owned passed 123k miles - specifically 123456 miles. What’s more, the trip computer almost made it read 1234567890!

As time passed, I was looking out for other odometer readings. 123465 miles was the next number of interest. The trip computer, however, didn’t complete the set.

Detecting Digits with PowerShell

Have you ever wondered, how many unique digits are in a number? Alternatively, how many times does a given digit appear in a number? Using PowerShell, I explore these questions in a variety of means and examples.

Producing live visuals from a PowerShell REST API

Fri, 17 May 2019 00:00:00 +0000

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:

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. Head over to dnsdumpster if you want to see an excellent example of that.

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.

TTS project update 1 - adding texture to my generated speech

Thu, 14 Mar 2019 00:00:00 +0000

TL; DR

In this post, I’d like to share an update on work to address some of the limitations in my text to speech project for Elite Dangerous.. Namely:

Single voice is used for the synthesis; and
Pitch, tone and emphasis are unchanged from defaults.

If you’d like to see the result of the work so far, here is a brief overview video, I’ll describe how we got here below:

Google Cloud Text-to-Speech with PowerShell

Sun, 10 Feb 2019 00:00:00 +0000

TL; DR

In this post, I’ll walk through the basics of using PowerShell to interact with the Google Cloud Text-to-Speech API. Partly a documentation exercise and somewhat a guide I’d like to have been able to read when I started on my Elite Dangerous Google Cloud Text-to-Speech project.

As such, we’ll start with a basic script to produce an audio file and explain how that works. Later I’ll walk through some parameters of interest to affect the response. Lastly, I’ll introduce how we can use SSML for a variation in response.

How to base64 decode on Windows 10 without base64.exe

TL;DR

You can call certutil from PowerShell to produce the required file.

Introduction

There is a moment in life where you get stuck in a quick start guide - we’ve all been there. At the start of my Google Cloud text-to-speech project it arrived quickly and unexpectedly at step two of this two-step quick start guide.

I had successfully returned my first base64 encoded speech audio, onward to the last step:

“Decode the source text file using the Base64.exe tool:”
