bravo ! Btw, anybody with in-RAM Puppy Linux on an Atom netbook other than me ? Mine is for my own Japanese-lang training app's to be a bit portable, but not Android or Win8. It can be tricky to get other languages in place on Puppy-in-RAM ... ( it takes about that 1 min to boot and then to setup a language environment that will survive, in my experience - a few single clicks at least) ... a small Pharo in that world would be great if the changes on device shutdown were written out auto-minimalistically ... but perhaps not as a those-sources-changes-are-one-big-file as that file sits out on an SD card at shutdown and probably must reload at boot/startup. Tiny executables still seem the way to go in Puppy ... but I am running one interpreter (Curl RTE) ad hoc. BUT ... it takes me much more time on my CentOS virtual server to set up node.js + selected HTTP server for a task via PUTTY and even more time to configure -a- Python version/enviro for some simple environment-sensitive scripting task ;-) And I don't think its just a matter of my 'nix shell scripting ! Android on x86 Atom is fun in its way for a few app's, but Puppy Linux in RAM - gotta love it !

Re: [Pharo-users] Which one should I download?

by Robert Shiplett

thanks I am already spread very thin and am reluctant to drop Pharo as I have no assurance that Dolphin Smalltalk is going to hang in there ... and I have health issues already in early retirement ( NOBODY even interviews a software developer over 60 in Canada - even though the Google guys I meet want me to keep their card ... but they FLY new grad's out to Mountainview ... - and then their are the customers who NEVER pay any bill before 90 days IF EVER. ) My fave languages outside Smalltalk are rebol, icon and MIT Curl ( all expression-based languages even if Curl uses regexp - that is Curl of www.curl.com , not cURL ) have been going through crises ... but even if Curl is squashed by Tokyo's SCSK Corp instead of breaking into Africa and China and India, Red as an alternative to Rebol has broken into China ... and oh what a bug-as-feature Rebol has been ! ) and ICON may yet survive the split into UNICON ( Rebol and Icon still struggle to be Unicode-compliant and Curl was always so as much as was the JavaScript that squashed StrongTalk/Self ... Of course France saw Prologia vanish into Air Liquide, so the fate of Curl should not surprise me. I am UTTERLY opposed to $$$ at the entrance for participation in a programming language ! Ralph Griswold would turn in his grave. And what a problem it was for Rebol and what a nightmare in the first decades of Smalltalk. Positive : Logtalk remains as a promising development for Prolog even if Prolog never gets a home in Smalltalk and Prolog still has a promising future in Mercury. So I am not WHOLLY discouraged at the end of my own career. But Oz/Mozart in emacs ? I would rather take Curl in eclipse ! ( If you never ran the docs in Curl IDE, then you have missed the closest thing to Smalltalk since MS QuickPascal's brief flame. And as a user of Borland C++ for OS/2 IDE at a time we were required to Use IBM WorthlessBench ... ;-) Any Smalltalker who fired up and reset and edited and saved code in Curl doc's viewer (cross platform) would NEVER want to to back to PDF let alone TeX tools -- unless they had already used StrongTalk 2.0 .... which most students graduate without ever being required to try. cheers, robert learning to read UNICODE Japanese one kanji and two-kanji at a time â from Shift-JIS and J-EUC and PDF pages ... in French and German and Russian ... without a Smalltalk-80 notes/e-book e-learning tool in 2014 ... 40 years / 4 decades after 1974.
