Faking Web to SMS so Synology can Notify via Slack

As bits of hackery go, this is pretty niche. I have a bunch of storage in a Synology Diskstation – this can send various notifications in case disks fail, components get too hot, or other bits of the system break down in ways that require immediate attention. It can send emails, you can use their app to enable push notifications to your phone and if you really want to you can have it send you SMS (actual SMS, in 2017?!).

I really like Slack.

As an excuse to try out the new Azure N series VMs with their NVidia GPUs, I found an email I recognised in one of the breaches, and followed it from hash through to brute-forced password to prove the point.

Impatience as Impetus: Building Alexa Sonos Integration

I’m impatient. I like new toys and new technologies and I generally don’t want to wait to play with them. We’ve been happy Sonos customers for years now, and Alexa customers since the UK launch. So when Sonos and Amazon announced a partnership to directly integrate the two in August last year, I was cautiously optimistic, albeit impatient to see it working. They promised a beta in 2016 and a launch in early 2017. I didn’t hear anything for the rest of that year, and wondered when we’d get an update on progress… Continue reading
