Empirical Analysis of Programming Language Adoption
by Ben Coman June 23, 2018

June 23, 2018

I bumped into a paper "Empirical Analysis of Programming Language Adoption" that I thought might be of interest to others since we'd like to increase Pharo's mindshare. (http://sns.cs.princeton.edu/docs/asr-oopsla13.pdf) TLDR; my top three take outs were... Figure 5 indicates that simple syntax and languages features don't attract new users, and of the things we can control the most important are... performance, portability and development speed. Figure 12 suggests a strategy to promote useful libraries rather than language features. I guess that might best take take the form blogs showing the use of libraries. Table 7 makes and interesting assertion that static types are more important for readability than preventing bugs. cheers -ben P.S. Then I bumped into "Toward Semantic Foundations for Program Editors" (https://arxiv.org/pdf/1703.08694.pdf) which was over my head but I guess it might be interesting to people working in UI area.

strange debugging
by Ben Coman June 22, 2018

June 22, 2018

Not sure if this is intended behaviour... in a brand new build 71053, open a browser GTGenericStackDebuggerTest >> testBasic right-click and choose "Debug" the debugger opens about on the third statement. Clicking <Restart> doesn't improve things, and then clicking <Into> shows the stack on MetaLink>>uninstall. cheers -ben

Fuel Error in Latest Launcher
by Sean P. DeNigris June 22, 2018

June 22, 2018

While Fuel was trying to serialize a sort block ([ :a :b | a name < b name ]), I got CompiledMethod>>errorSubscriptBounds:. One strange thing about the block is that the outerContext is `SortedCollection>>DoIt`, meaning I probably had to initialize it by hand due to a previous Fuel problem. The odd thing about the error is that this object graph was serializing and materializing just fine before I upgraded Pharo Launcher. Call chain: CompiledMethod(Object)>>errorSubscriptBounds: CompiledMethod(Object)>>at: InstructionStream>>interpretNextV3PlusClosureInstructionFor: OpalEncoderForV3PlusClosures class>>interpretNextInstructionFor:in: InstructionStream>>interpretNextInstructionFor: [ (InstructionStream new method: self pc: pc) interpretNextInstructionFor: nil ] in CompiledMethod(CompiledCode)>>abstractBytecodeMessageAt: in Block: [ (InstructionStream new method: self pc: pc)...

Seaside loading broken in Pharo 7
by Torsten Bergmann June 21, 2018

June 21, 2018

Hi Pharo-dev (CC Seaside-dev) the Seaside PR on discussions for Pharo 7 supprt on https://github.com/SeasideSt/Seaside/pull/979 says one should use Metacello new baseline:'Seaside3'; repository: 'github://SeasideSt/Seaside:master/repository'; load. to load Seaside in Pharo 7 (which was from around 7th of February) I today tried with latest 70694 fresh Pharo image but after a while I get many walkback debuggers with #setToEnd, isReadOnly and #closed not implemented on ZnCharacterReadWriteStream while it is loading "Zinc-Character-Encoding-Core-SvenVanCaekenberghe.56" If I remember correctly I was able to load it in P7 two weeks ago - so something broke it meanwhile. Any ideas? Bye T.
