After some researches I ended up with Wallabag as well, hosted on wallabag.it.
I've got a lot of things saved, sometimes quite long articles (I read a lot, but I save a lot more)
The ePub export was a requirement for me since I moved to Kobo (originally for the Pocket compatibility) after old Pocket app on my 1st gen iPad Mini stopped working.
I made some test to self host it but the epub export and the images caching was to much for my Synology NAS. I had some good results with a more powerful machine but I didn't want to keep it running 24/7.
And finally the export works well on wallabag.it so I though the hosted version worth its price!
I've found a dealer who has a late-2012 mac mini display piece. This particular machine can be upgraded to 16Gb. Im probably going to go with this config.
My reasoning was "what if an HN reader is trying to rent their apartment in Paris". The probability is so low, but for problems that are not usually recurring, you can find help in the most unexpected places.
PS: I am not relying on HN for this, I am using other rent specialised services as well. This was just a message sent out in the universe, if caught by the right eye I'll go from 0 to 1, otherwise, I am staying in 0, not going to -1.
I totally recognize myself in what you are saying.
I'm waiting to finish my current project (I do freelance contracting) to be able to get back on my own projects and focus on something... but I have the same lake of good ideas lately, or at least I don't really believe in my ideas anymore.
You should consider working on really early stage projects, building MVPs, maybe for equities rather than money.
Mac Mini with a wide screen (>22") + an iPod touch as testing device may help
keep in mind that you can run Windows or even Linux on a Mac if you're into that.
The hardware will handle it pretty well.
I'm an experienced iPhone/iPad developer.
I'm also able to work on backend (Rails), web development (Rails/PHP) and system administration (Linux, Mac OS, and Windows)
