The iPhone has a small DHCP address pool that can give out 16 addresses (172.20.10.0-172.20.10.15). Of these 16 addresses are 3 taken by the network, broadcast (172.20.10.0 and 172.20.10.15) and iPhone itself (172.20.10.1). Leaving 13 addresses for other devices.

Reimaging First-gen Surface Hub with Surface Hub Recovery Tool (SHRT)

First-gen Microsoft Surface Hubs require you to pull the SSD out the back and reimage the disk on your PC with a SATA to USB adaptor in order to run recovery. The utility requires the SSD to be enumerated as a Lite-On drive, otherwise the tool will sit there doing nothing.

Lezyne GPS Power Target

The bike GPS market has expanded quite a bit the past few years, especially in the budget end. Lezyne now has a wide range of competitive GPS units in this segment, but they are still lacking in features, in this case a power target widget/page.

Shimano drivetrain compatibility

I made a comment on a reddit post last year summarising all my research into Shimano drivetrain compatibility at the time, as I was upgrading from Claris 8spd to Franken-bike 10spd setup with Tiagra 4700 shifters (10spd) and 105 5800 derailleurs (11spd). I wanted to refer back to it today for further upgrades/changes, but reddit’s poor search made this a massive pain, so I’ve simply linked to it here for my own future benefit.

Email forwarding/redirecting not working with O365

Siren backup battery replacement

Unknown to many (myself included), the siren mounted in the boot of the 1st gen IS—which the car alarm uses in tandem with the horn—actually contains a backup battery.

Connecting Outlook 2016 to Office 365

Let say you go to connect Outlook 2016 to an Office 365 mailbox. You would go to mail settings, perhaps add a new profile if you already have old mail profiles you want to keep. As part of the process Outlook will proceed to an email address configuration wizard.

Checking ashift on existing pools

So I have an existing pool that was created several years ago on an old build of FreeNAS, and I wanted to check and see if the ashift was set correctly for 4K, meaning I want an ashift=12 (2^12=4096).

Recover FreeNAS config file

So I set up a FreeNAS server 15 months ago, but now I live >7000km away and it decided to kick the bucket. And guess what? I was dumb enough not to make a backup of the config file or the boot USB itself.
