Did you know you can run remote Linux GUI programs in a browser with HTML5 support? It’s even secure because you can use SSH tunneling and that little trick means you don’t even need to open additional ports. If this sounds like gibberish, read on, it’s actually pretty easy to get up and running.
I recently was a guest on a Houston-based podcast, and the hosts asked me if the best thing about writing for Hackaday was getting to work with the other Hackaday staff. I told them that was really good, but what I like best was interacting with people (well, most people) in the comments. That sometimes you’d post an article and someone would bring a topic up in comments that would really knock your socks off. This is how I wound up with this nearly ideal remote access solution, that requires nothing on the remote side but a web browser.
A while back I posted about keeping programs running after log off on a Linux box. The post was mostly about non-GUI programs but you could use NX or VNC to handle it. In the comments, someone mentioned how unhappy they’d been with recent copies of NX and another commenter called [Screen for X11] posted about a tool called xpra.

Pervasive connectivity is a mixed blessing at best, especially when it creates the expectation that we’ll always have access to everything we need. When what you need is on your work or home PC, there are plenty of options for remotely accessing files using your phone. But if your roomie or the cleaning crew powers the machine down, you’ve got a problem – unless you’ve got a way to remotely power the machine back up.
[Ahmad Khattab]’s hack required getting up close and personal with his PC’s motherboard. A Particle Photon steals power from the always-on 3.3 volt line of the vacant Trusted Platform Module connector on his machine. Outputs from the Photon are connected to the motherboard’s power switch connection and a smartphone app drives the outputs and turns the machine on and off. As [Ahmad] admits, there are plenty of ways to attack this problem, including Wake-on-LAN. But there’s something to be said for the hardware approach, especially when a Photon can be had for $20.
Astute readers will note that we recently covered a very similar project using a Particle Core. Be sure to check that one out for a little more detail on using Particle’s cloud, and for some ideas on powering the module if your motherboard lacks a TPM port. In the meantime, enjoy [Ahmad]’s video.
