MarkX: Query Markdown Like XML in PowerShell
I saw MarkX 0.1.4 announced with Hugo support and pointed it at this blog, where Hugo already renders every post. It had nothing to add. It fits elsewhere: tables as data, link audits, objects as tables.
Your Function Accepts an Array. Piping One Is Different
I shipped CaOutcome with 204 passing tests and a README example that gave thirteen wrong answers. Every test passed the collection by parameter. Maester pipes it, and PowerShell unrolls a piped array.
Find memberOf Rules Before November 3
I found MC1448379 while hunting for my next post: on November 3, every memberOf group, administrative unit and auto-assignment policy stops updating. Microsoft says grep for the word. I wrote a parser.
Nothing Alerted When My WAN Dropped to 100 Mbps
On 10 September my UDM’s WAN port renegotiated to 100 Mbps and stayed up. No alert fired, and the house sat at 178 ms for hours. I traced it to a cable and wrote a poller to catch it next time.

One VM running qBittorrent was pulling about 98% of my WAN traffic. I capped it in qBittorrent, shaped the WAN with Smart Queues and aimed a UniFi throttle at it. Only some of those limits bind today.

In August I moved my UDM Pro to UniFi’s zone-based firewall and left it alone for two months. When I read the policy list back, three rules pointed at a machine that stopped being Plex a while ago.
Entra Is Retiring 58 Sign-in CSS Properties, and the First List Had 19
On October 19 I found a Message Center post: Entra stops honoring layout CSS in company branding on October 26. The news listed ten properties. Learn lists 58, display included, so I built a scanner.
Where to Start With a Broken Intune Script
My Widget detection exits 0 with nothing on stdout, so Intune installs the app, can’t find it and reports 0x87D1041C. This index maps each portal symptom to the IntuneScriptLab command behind it.
