New Cog VMs available
by Eliot Miranda June 25, 2014

June 25, 2014

... at http://www.mirandabanda.org/files/Cog/VM/VM.r3018/. The main difference here is fixes to memory segment allocation on Spur. Linux and Mac OS can now grow the heap to 2.9Gb or there abouts, and Win XP can grow to 1.8Gb. I'm interested in reports on other Windows versions that don't have XP's 2Gb user process address space limit. Here's my test script: | them | them := OrderedCollection new. [[them addLast: (ByteArray new: 16000000). Transcript cr; print: (Smalltalk vmParameterAt: 3) / (1024*1024.0) maxDecimalPlaces: 1; flush] repeat] on: OutOfMemory do: [:ex| 2 to: them size by: 2 do: [:i| them at: i put: nil. Smalltalk garbageCollect]]. Transcript cr; print: (Smalltalk vmParameterAt: 3) / (1024*1024.0) maxDecimalPlaces: 1; flush. them := nil. Smalltalk garbageCollect. Transcript cr; print: (Smalltalk vmParameterAt: 3) / (1024*1024.0) maxDecimalPlaces: 1; flush And the README is: CogVM binaries as per VMMaker.oscog-eem.779/r3018. Rewrite memory allocation on linux for Spur. Arrange that the heap can grow above 2Gb without any large initial alloc. Rewrite platforms/unix/vm/sqUnixSpurMemory.c to stand alone. Use it in place of sqMacMemory.c with Spur on Mac OS. Now Spur can grow the heap to 2.9Gb on both linux (CentOS 5.3) and Mac OS X (10.6.8). Rewrite Spur memory allocation on win32 similarly to unix. Can now allocate up to 1.8Gb on Windows XP (which has a 2Gb address space limit). Add a flag to indicate if the win32 exe is running as a console app and don't write to the in-window console if so. Fix some sign issues with free space tallying to allow Spur to shrink memory and answer via primitiveVMParameter heap sizes above 2Gb. Add longPrintInstancesOf:/longPrintInstancesWithClassIndex: for debugging. Suggest reading a suitable README when the linux VM fails to spawn the heartbeat thread. Add parameter 54 on Spur to answer totalFreeOldSpace. -- best, Eliot

[Tutorial] Rediscovering the UX of the legendary HP-35 Scientific Pocket Calculator
by Sven Van Caekenberghe June 25, 2014

June 25, 2014

Hi, I have written a new, extensive, long form, introductory article about Pharo. Rediscovering the UX of the legendary HP-35 Scientific Pocket Calculator A tutorial on Pharo, test and specification based immersive programming https://medium.com/@svenvc/rediscovering-the-ux-of-the-legendary-hp-35-scie… It is a bit different because - it is based on a non-trivial example - it uses a backdrop story unrelated to Pharo - it uses several multimedia elements - it is published on medium.com which is a general publishing platform The appendix describes several ways you can get the code. I think building both a Spec and Seaside UI from the same specification as well as reusing functional tests in different contexts is cool. Anyway, I hope you enjoy it.
