**So, the JingPad A1 has come and gone, I suppose by the time this is published in 2 months, things may be different, but I think it died somehow. CuteFishOS last had action on July 3 (and a nothing the month before), another promising project seems to be dead in the water. Why do we have the spectacular rise & fall of Linux projects? As soon as something “nice” comes to Linux, it seems to go silent. I recall such projects as PearOS. Not the thing that parades itself around as that now, but PearOS 7, I think it was the last decent version that was faster than the OS it was based on with nifty tools. PearOS 8 was incomplete iirc and the website died when it go “released”. We could go full conspiracy here and say M$/Apple paid them to stop, but it seems unlikely. I suspect the final message was to mess with us: “Pear OS is no longer available for download. Its future is now in hands of a company who wants to remain anonymous for the moment. The concept has pleased them it and now wants to continue and improve the system for their own products. I can not give a name but it is a very large company well known ...” What causes a developer to abandon a project, whilst other projects live on? Money does make the world go ‘round and I have seen brilliant projects canned because the profit margin would be too small. The business side of things kills the innovation. Is this the reason Red Hat wants to drop games from the repository? Should there be a Kickstarter-type place for Linux projects? Could it be attitude? As with anything in life, practise makes perfect and I am thankful to my current colleagues for letting me do all the work whilst on shift, I could look at it and go; why should I do it all, or, take the practice an stay on top of the game. I learn more, I don’t get bored, I get my muscle memory. I do not see a down side. So is it attitude that needs to change? I don’t know the answer to these questions as I don’t run any open source projects. If you have any insights on these issues, let us know.** | **So, the JingPad A1 has come and gone, I suppose by the time this is published in 2 months, things may be different, but I think it died somehow.

I have an image, so I just restore that when I run out, so no real biggie. | + | **Q: Hi. I have started to learn Ubuntu server and my “server” is an i3 with 128gb SSD and 4G memory.
