Netgate (behind pfSense) use PHP for their firewall administration interface.

They recently posted about how to patch their software from the command-line (https://www.netgate.com/blog/critical-php-security-update)

KOReader [1] is my favorite reader. Pairs well with my syncthing library of ebooks (I just keep the phone's copy in read-only mode).

Koreader interface with syncthing is not that user friendly to non techs, very powerful can do anything but i don't think i would advise that to non techie

KOReader can update over WiFi as well, right?

You mean whether the KOreader software can upgrade itself over Wi-Fi? Yes... it can.

Episteme is pretty good

Just to add, KOReader might not look super use friendly at first, but I highly recommend giving it a try. It’s an amazing reader.

Once your used to it, the controls are a lot better than stock kindle as well imo.

To add to this, since the original comment mentioned kindle, you can jailbreak many of the models and install KOReader in them if you want to keep using the hardware.

And then you can automatically sync your reading process with the KOReader phone app. I use that functionality almost every day for when I don't have my Kindle with me (train ride, lunch break etc).

Using readera with network connection disabled. Super app.

I've taken StreetComplete with me on walks around my neighborhood and on a few vacations. It was really easy to submit data for missing items.

I did my first contributions last week with it. Really easy and the UI is simple and nice.

On a Rubiks cube, the center tile always remains constant. I was surprised at this when I accidentally broke one apart to find a static 3d cross piece to each cube face (e.g. a non-moving tile). Everything else rotates around it

Thanks for pointing out ReManager. After moving to the Move, I've sorely missed my handful of toltec packages (koreader, etc.).

Left 4 Dead handled this pretty well in my opinion (i.e. mob spawning behind if you're playing too slowly or a tank in front if you're going too quick). I absolutely hated the dynamic adjusting in games like Mario Kart, though.

Or Descent. Pity the fool who hits the map key mid-multiplayer fight.
