Merriam Webster defines "agile (technology)" as "synonym for trash".

Agile, their team delivered a Minimum Viable Product

I guess that's kind of what got me into this mess.

They have some shitty web application where you're supposed to log times your kids will be in daycare. I logged in, looked around - and told the wife she can chose to log times herself, or tell daycare to do it themselves. I'm paid to deal with broken shit in my main job, I'm not doing that for free in my spare time.

At that point I assumed the web app was some prototype their intern had thrown together for the sales pitch, and they were now desperately trying to get it functional - to my surprise I later learned that it was an older product, with quite a few customers already.

Few weeks later wife came back upset from kindergarten over an argument about missing times - which forced me to actually deal with that dungheap, and prompted me to have a closer look at other components, like the android app they're using on their phones as well. There's a lot of stupid beginners mistakes in all components - not necessarily exploitable, but I also didn't really check as in my opinion the tag thing would be sufficient to have this taken out of use.

Doesn't having an account require an online system? By making the card authoritive you can build and offline system.
