Been using it for 6 months!

No issues so far, nor do I miss feature _X_ from previous readers I've used.

I don't use the Importance filters.

Never though someone would actually prefer a command line image editor over a GUI equivalent. Now I know a faster way to convert or resize images and I don't even have to leave the keyboard! :-)

Wow!!! I had no idea. Thanks for the link. :-)

Indeed. As for space exploration goes I don't remember if it was The Martian or Interstellar which mentions Nasa's Jet Propulsion Lab (JPL). And from there I found this nice article about Lisping at JPL, by Ron Garret [1]. I think it's an enjoyable reading.

SISCOG [1] uses on all their products. Actually they use Allegro CL from Franz. [2]

The main reason (for still using it) being that it all started out as an end of college project, by the two CEOs, around Artificial Intelligence proof-of-concept-general-tools (so to say) until the big breakthrough for danish railway company, NS, which was impressed with their fleet scheduling project. This adventure began in the late 80's and they were using Lisp Machines!

I suppose the reason for still using Lisp to be a mix of i. there is no technological necessity to change; ii. the codebase of existing products is too big to translate; iii. CTOs don't have enough knowledge on other technologies to evaluate the feasibility of a change; iv. many of the developers actually love Lisp :-).

Most of the support technology is also done in-house and they don't tend to use many external libraries.

I wasn't aware Sublime has a trial period thus I included on the list.

I edited the post a bit to accept non-free editors as well.
