We should write the proposal. I only write the title and those 2 lines because I though it was a good idea but I don't know more than what I wrote. I have no idea about OpenSSL....so, any help with the proposal is more than welcome.

This sounds REALLY greate. PLEASE take a look to http://gsoc2010.esug.org/application.html the answer to point 2).

The only thing I am concerned a bit is the scope of the project. It seems quite big. Maybe you should scope it and put "must have" but also "wish list" or bonus items.

[Pharo-project] Full time engineer position for Pharo looking for cool engineer :)
by StÃ©phane Ducasse March 10, 2010

March 10, 2010

Hi guys Some good news :) INRIA-lille nord Europe ranked Pharo among the top 3 projects that will receive support for a full time confirmed engineer. We will know if the national level or the lab will carry the cost by mid april, but for now the position is allocated to Pharo. This is not the official job announce but just to give some hints and that you can prepare yourself to - move to France (one hour from paris, 1h30 from London, 35 min from Brussels) - try a lot of good beers (belgium :) - eat french food - have fun with us - yes we are even fun - ok with geeky humor :) - code all the day in Smalltalk and a bit of C Apparently from what the DHR services told me, the salary will depend on years of expertise and diplomas but we can think that 2700 Euros (before final taxes) should be a good working number -- In France the employer pays already taxes so the salary is not brutto but already includes deduction. The social insurance is included and you may want to pay an extra like me (100 Euros) to have a better health insurance. Lille is an active city but not expensive. To give an idea Marcus got a nice sunny close to everything flat with wooden floor for 650 Euros. The job will to continue making Pharo (core) better - better tools - better network support - helping with the new compiler - helping with alien and others - cleaning/shrinking Duration: 30 months Starting date: October 2010 Location: Lille (no remote job possible) Do not hesitate to contact us.

[Pharo-project] Something I don't understand with ImageSegments
by Mariano Martinez Peck March 10, 2010

March 10, 2010

Hi guys: I have this little (piece) of test: | segment external internal root | external := 'mariano'. internal := true -> external. root := false -> internal. internal := nil. segment := ImageSegment new copyFromRoots: (Array with: root with: external) sizeHint: 5000 areUnique: true. self assert: segment outPointers size = 2. And that is green. However, if I change 'mariano' to Object new, I have that segment outPointers size is 3 instead of 2. I really don't understand why. Does someone see something ? Thanks Mariano

[Pharo-project] [update 1.1] #11256
by StÃ©phane Ducasse March 10, 2010

March 10, 2010

11256 ----- - Issue 2127: CrLfFileStream comment Adds comments, reroutes default lineEnd setting methods on CrLfFileStream, and deprecates basicNew, just in case someone is using that. Issue2118 LetUnicodeLeadingCharBeZero-Part5 - fix some additional users of leadingChar = 0 (text composition must check ascii < stops size) - fix a forgotten crlf Thanks a **lot ** nicolas. When I read this code it looks a bit complex and so difficult to debug :) and I appreciate that you take the time to help. Stef (now running to the doc with sick boy).... life is forcing you remove your hands from a keyboard.

[Pharo-project] CrLfFileStream class>>new?!
by Adrian Lienhard March 10, 2010

March 10, 2010

I was just puzzled why "CrLfFileStream defaultToLF" does not work until I figured that CrLfFileStream new returns an instance of a different class: CrLfFileStream class>>new ^ (MultiByteFileStream new) wantsLineEndConversion: true; yourself. Does somebody know what the point is? I really sometimes wonder why good coders write such code, and not even care to add a comment... Cheers, Adrian ___________________ http://www.adrian-lienhard.ch/

They fucked up our lives. Possibly. But fanaticism has its share of guilt too. I have my opinion on what's worse. Paolo
