Go Home Android Discover, You’re Drunk

OK Google: We need to talk. I’ve used and loved Android OS phones for a LONG time now and lately, I really enjoyed the Cards feature in pure Android (Nexus, Pixel, etc). But unfortunately, you changed it to¬†Android Discover and it’s mind-numbingly frustrating and useless now. It used to show reminder cards about upcoming package deliveries, useful news stories and calendar reminders…now it’s almost like it just picks random words from my search history (or … Read more…

Installing Citrix ADC (NetScaler) on Proxmox

A few days ago, I did a thing and one of the first issues I had was getting a NetScaler (Citrix ADC) appliance up and running on the new host…because, you know….priorities. This scenario is certainly supported as the hypervisor is KVM, but on the initial boot, it got stuck here: And that’s no good. How did we get here?

Troubleshooting Tips for Citrix ADC (NetScaler)

I’ve collected numerous Citrix ADC (NetScaler) troubleshooting tips and commands over the years, so here they are. Note that some of these tools, file paths or methods may have changed over time.

Powershell Duplicate file Cleanup for Plex Camera Uploads

Some time ago, my wife had her phone stolen and we had not setup any sort of backup for the pictures, so a good number of photos and videos of our kids were lost that day. We now both use Google devices, so we have automatic backup to Drive for free, but I didn’t want to rely only on that. Enter Plex Camera Upload We use Plex a lot in our house – one of … Read more…

Sophos XG Firewall LTE Backup

I work a good bit from my home office so obviously internet access is pretty important – so important that I have 2 carriers: Comcast via coax and AT&T via bonded pair DSL. As you may also know, I use the Sophos XG firewall home edition as a full-featured firewall and internet gateway – the conversion from Sophos UTM to XG was a bit tricky due to the UI of XG being…let’s just say not … Read more…

‘Thank you’ to Citrix and the Community

I started my professional technology career as a help desk administrator supporting a small healthcare organization that was still using something that was called Citrix Metaframe XP – it was the first time I had dealt with a real IT infrastructure, and also the first time I interacted with a Citrix product. That was nearly 13 years ago. After that, I interacted with Metaframe and XenApp (among other products) on and off until I started … Read more…
