Raspberry Pi shutdown button

We have a small but growing collection of Raspberry Pi devices here. They’re performing a range of tasks: one’s our Pi-Hole, another runs the “Homebridge” middleware between Apple’s HomeKit and our Clipsal C-Bus, whilst a third is running the management app for Ubiquiti UniFi. And of course plenty more are strewn around the place running …

Begin-Process-End in a PowerShell script

Much has been written about how you need to use Begin/Process/End blocks in order to handle a collection of values passed from the pipeline, but those posts all seem to focus on how to do it in a *function*, not a script. I recently struggled to figure out how to retrofit this functionality into one …

Adventures with Import- and Update-CsUserData Pt.4

I’ve spent a lot of time in the past 12 months working with the <verb>-CsUserData commandlets in SfB, and it’s been an interesting time. This is part 4 in a series where I document the traps I’ve fallen into with the Import-CsUserData and Update-CsUserData commands in particular. Part 1 – Update-CsUserData fails on bad data. …

SfBS RGS lets you spoof a SIP Domain

  A long-standing bug in Skype for Business’s Response Group Service (“RGS”) is that it doesn’t validate the line URI when you create a new Workflow. This means it won’t err out if you chose a number that’s already in use elsewhere, and the upshot is that neither the existing user nor the response group …

Get-WeatherLinkData.ps1

We’ve had a Davis Instruments Vantage Vue weather station on the roof for some time now, and with the addition of the “WeatherLinkIP datalogger” its data is uploaded to the greater Davis WeatherLink platform automatically. Their service is subscription-based, and we’ve not seen sufficient value in giving them ~AUD5/month to have access to the historical data, …

2020 mugshot: an ivory 400-series handset

The phone in my ‘mugshot’ this year is, like me, quite a relic. It’s an ivory-coloured handset from a 400-series phone. At the start of last century telephones were typically constructed of timber or metal. It wasn’t until the late 1920’s that the British Siemens company developed the first plastic phone, made of a “thermo …
