[Pharo-project] Are Objects really hard?
by Janko MivÅ¡ek Feb. 27, 2012

Feb. 27, 2012

Hi guys, Again one interesting topic for this weekend to discuss. David Nolen, a Lisp and JavaScript guy posted in his blog an article titled Illiterate Programming [1] where he said: "...Yet I think Smalltalk still fundamentally failed (remember this is a programming language originally designed to scale from children to adults) because *Objects are really hard* and no-one really understands to this day how to do them right...." He links to Alan Kay post [2] back in 1998 where he talks about problems with inheritance: "Here are a few problems in the naive inheritance systems we use today: confusions of Taxonomy and Parentage, of Specialization and Refinement, of Parts and Wholes, of Semantics and Pragmatics..." Let we concentrate on broader "Objects are really hard and no-one really understands to this day how to do them right" claim and not merely inheritance, please. Best regards Janko [1] http://dosync.posterous.com/illiterate-programming [2] http://lists.squeakfoundation.org/pipermail/squeak-dev/1998-April/009261.ht… -- Janko MivÅ¡ek Aida/Web Smalltalk Web Application Server http://www.aidaweb.si

Is there a way to programmatically set the title of a pharo image on startup? I grabbed the first level pasteup morph and tried to play with it but I didn't find the intended method. thanx usman

[Pharo-project] So I broke 8k req/s today
by Philippe Marschall Feb. 27, 2012

Feb. 27, 2012

Hi I heighten everybody's mood I'll post some positive news. After some optimizations in both Seaside and AJP I managed to break 8000 requests / sec with a single Pharo 1.3 image. Thanks to SystemProfiler I knew where to look. This is with a single request handler that just returns a two byte response. It doesn't involve any rendering, sessions, continuations or whatsoever but it kicks on the full Seaside request handling machinery with a request context and everything. I'm using WASmallRequestHandler from the Seaside-Benchmark package. WASmallRequestHandler >> #handleFiltered: aRequestContext aRequestContext respond: [ :response | response binary; contentType: WAMimeType textHtml; nextPutAll: 'OK' asByteArray ] Apache 2.2.21 mpm_worker mod_proxy_ajp CPU Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz SmalltalkImage current vmVersion 'Croquet Closure Cog VM [CoInterpreter VMMaker.oscog-eem.138]' Attached you'll find the output of ApacheBench. Cheers Philippe

[Pharo-project] [JOB, Academia] PhD Position at INRIA Lille
by Marcus Denker Feb. 27, 2012

Feb. 27, 2012

INRIA has a new call for PhD Student positions. Description ============ To support the creation and evolution of complex systems, dynamic languages provide support for reflection. A reflective system contains a model of itself to enable runtime change: if we change the model, the system changes and vice versa. Reflection allows the programmer to do any kind of change at runtime, even those that render the system useless or breach any kind of security guarantees. Reflection is an established research theme and has seen a lot of work over the last decades. The question of how to control reflection and related that of secure reflective systems in general has not seen much research activity. The goal of this PhD is to propose a new secure reflective language kernel for dynamic languages. The following points should be explored: - Study existing models of security. - Study existing reflective systems and especially prior work on security and reflection. - Propose a new, secure model of reflection. - Implemented the model in a dynamic, object-oriented language.

Hi guys This version of ecompletion will work on pharo1.4 (i.e. enhanced shout packages) and new text editor (so cool). MCHttpRepository location: 'http://ss3.gemstone.com/ss/NEC' user: '' password: '' Feedback is welcome of course. I'm currently renaming the classes to avoid clashes and I will clean it a bit and check OCompletion. Stef
