I’m convinced that the Erasmus programme (and it’s not so serious counterparts such as AEGEE and IAESTE) contribute to lasting peace in Europe by marrying people between nations.
If _one_ bad experience turns you into a lost customer, then this business model purely operates on the happy-path and hopes for the best.
I am highly sceptical that the core promise “anything, anytime“ is really what people need: they use it, because it’s possible, not because they want to use it.
The alternative to your problem would be asking a friend/relative to do the shopping, using the in-house delivery service or simply make do without. All more secure options than ordering something and not being sure, you’ll actually get it.
I say good riddance for this petty excuse of a business!
I second PowerApps. There’s a to user-friendly tutorials out there and their programming model is based on concepts similar to Excel.
It should be fairly easy to pick up for end users. But only if you don’t use denormalized tables. If your DB is in 2/3NF you’ll run into issues, e.g. the ever so useful DataTable cannot update data across table.
Also, there’s a pretty significant hard limit on 500 rows.
PowerApps is a great tool, but be aware of its limitations and see if that works for you.
LO has its own platform abstraction layer (called SAL), which only supported pixel-precise layout of elements. That meant that the longest string in any of the supported languages dictated the element layout.
Caolán McNamara (of RedHat) added support for automatic layouts a few years ago. Since then, LO has been cleaning up its dialogs and has innovated a lot (e.g. by introducing the notebook bar). This simply wouldn’t have been possible previously. Compare it with Apache OpenOffice and you’ll see why.
As an Austrian myself, I'm not at all surprised at their reaction. To them, their website is "just IT stuff" and they simply don't have a notion that it would involve any security.
To them you'll likely seem like an overzealous geek that shouldn't mess with their business website. I've experienced this before myself and it's not particularly a good position to be in.
Their site has most likely been technically abandoned, i.e. no one capable is in charge anymore.
It'd be best to talk to the owner, show them your "hack" (change it to cats on your phone and let them verify in their browser) and offer them to fix it for free.
That's how one does these things in our small country. ;-)
