by Sven Van Caekenberghe

Dear Fellow Pharoers, We are happy to announce a new initiative, a listing of Pharo Consultants, http://consultants.pharo.org If you are able and willing to provide professional Pharo Consultancy services and would like to be listed as such, please send the necessary info to board(a)pharo.org so that we can include you. This is a listing of individuals. Apart from your knowledge of and involvement with Pharo itself, the only requirement is that you are either a paying Pharo Association (http://association.pharo.org) member or related to one of the members of the Pharo Consortium (http://consortium.pharo.org) The recorded information is minimal, but includes a link to a website. The order of the listing itself is randomised each time it is generated. Your email address will be obfuscated a bit to limit spam. As a Pharo Consultant, you can advertise that fact using a nice URL, http://consultants.pharo.org#seandenigris Cool, right ? Please provide your info in one of the following forms. Smalltalk expression: PharoConsultant new name: 'Sven Van Caekenberghe'; location: 'Hasselt, Belgium'; email: 'sven(a)stfx.eu'; website: 'http://stfx.eu'; languages: 'Dutch (native), English, French, German'; industryExperienceSince: 1990; smalltalkExperienceSince: 1993; pharoExperienceSince: 2010; areasOfExpertise: 'Web Services & Applications, Servers, Networking, Protocols'; yourself STON: PharoConsultant { #name : 'Sven Van Caekenberghe', #email : 'sven(a)stfx.eu', #website : 'http://stfx.eu', #location : 'Hasselt, Belgium', #languages : 'Dutch (native), English, French, German', #areasOfExpertise : 'Web Services & Applications, Servers, Networking, Protocols', #industryExperienceSince : 1990, #pharoExperienceSince : 2010, #smalltalkExperienceSince : 1993 } Regards, Sven, on behalf of the Pharo Board.

For Pharo3, we even opted to not support decompilation at allâ¦ (IR -> AST). We will instead save a higher-level representation that has much more information (e.g. names of variables). For deployment, people can strip the names, giving them the same "obfuscation" the decompiler provides now. BC-> IR decompilation always works. Marcus

Just a theoretical question: Can every sequence of bytecodes be decompiled to a Smalltalk method? I doubt it but wanted to ask nevertheless. Best Regards, Udo

Re: [Pharo-users] 3.0 almost green

I have to defend my test ;-) No seriously: ReleaseTest is there to guard quality (but #testMethodsWithUnboundGlobals is skipped). They all pass in my 3.0 image that I have been developing in for some days now. So that is really nice. Ideally, we should not weaken the rules, but try to understand why it behaves so strangely. Maybe some bright soul can rewrite the test so that is less brittle. Sven

You can have the HTTP handler return information back and this way you can easily send out emails if an expectation isn't met in the image. Norbert
