[Pharo-project] wikiserver 1.4.4 promo codes
by John M McIntosh Aug. 8, 2009

Aug. 8, 2009

Apple approved WikiServer 1.4.4 for sale on the App store yesterday, as usual they have handed us another 50 USA promo codes, so if there are people on the list that would like one or two, please email me, not the list, a request. I note these are for USA itunes customers, but there are ways for people to create a new dummy itunes USA account with out supplying credit card information to redeem the promo code then install the app on your device for a month of free usage. Since we now support the ability to export the wiki data and run on a desktop version it's easy to preserve any data for later importing into a purchased version. -- = = = ======================================================================== John M.

[Pharo-project] Cursor theming
by Torsten Bergmann Aug. 8, 2009

Aug. 8, 2009

>Sorry, not had time to make a new set of cursors. OK, until then I themed with win-like cursors. See the attached file. Just evaluate CursorReplacer new replaceCursors if you dont like the default cursors. Since these are similar to Vista cursors the cursor does not change on this OS when you enter the pharo window. I dont know if we can have the correct cursors for each platform included in the image by default, there may be copyright issues. Note that the code just replaces the contents of the class variables and does not change the hard coded Squeak cursors, so old cursors could be restored if required. Take care when you theme with own icons: beside the class variables in class Cursor you also have to change a form instance in class HandMorph which is used when dragging windows on the pharo desk.

Thats a problem of some sort in configure, but note also that RomePlugin will not work on 64-bit systems (Mantis 7344).

Re: [Pharo-project] Subtle behavior changes in UI threads for Pharo?
by Dale Henrichs Aug. 8, 2009

Aug. 8, 2009

Stef, I'm not sure that concurrent use of the ThreadSafe Transcript is any more or less dangerous from the foreground process than from background process. I've experimented with a mod to ThreadSafeTranscript>>endEntry that allows for both foreground and background updating of the transcript. The following expression: | tt | tt := (Smalltalk at: #Transcript). "Background updates" [1 to: 20 do: [:i | tt nextPutAll: '[', i printString, ']'; nextPutAll: '*'; flush . Processor yield ]. tt flush ] fork. "Background updates" [100 to: 120 do: [:i | tt nextPutAll: '{', i printString, '}'; nextPutAll: '-'; flush. Processor yield ]. tt flush ] fork. "Foreground updates" 200 to: 220 do: [:i | tt show: '---', i printString, '---'. Processor yield ] produces this output in the transcript: ---200---[1]{100}*---201----[2]---202---*{101}----203---[3]*{102}---204----[4]*---205---{103}-[5]---206---*{104}----207---[6]*{105}---208----[7]*---209---{106}-[8]---210---*{107}----211---[9]*{108}---212----[10]*---213---{109}-[11]---214---*{110}----215---[12]*{111}---216----[13]*---217---{112}-[14]---218---*{113}----219---[15]*{114}---220----[16]*{115}-[17]*{116}-[18]*{117}-[19]*{118}-[20]*{119}-{120}- I protected the #changed: message and the #displayWorldSafely with the access semaphore so at a minimum concurrent transcript accesses shouldn't be a problem. With this mod,the transcript updates when called from a lone foreground process, too. If you want, I can can submit a bug along with the proposed fix...Alternatively, I think I've probably got enough info to fix my problem in isolation. Hmmm, perhaps WorldState needs a mutex to make #displayWorldSafely truly safe?
