Unique identifiers
by Esteban A. Maringolo May 21, 2014

May 21, 2014

I would like to discuss alternatives for the generation of unique identifiers, in the context of URLs, database primary keys/no-sql keys, system interoperation, etc., etc. I used GUIDs in the past, which for simplicity I stored them in its string representation instead of using the byte/long representation. Do we have something other than UUID (16byte/36chars) to create identifiers? Does exist a shorter (ie. 8byte) UUID version? I know its uniqueness comes from the extra bits, but maybe a shorter display string can be used (as git commits does, but with 20 bytes) or directly less bytes like MongoDB's OID (12 byte). I'm thinking about unique identifiers in the context of different systems (and different languages), where datatype limitations can exist. E.g. Java's long is 2^64 -1, 8byte, SQLite can only store 8byte integers. So the most standard generator, least common denominator type would be the best approach. By now, the "least worst" solution I found is to keep using the 36 char string representation for persistence/serialization (JSON). But I'm sure there must be something else much more clever. What do you use for IDs? Regards, Esteban. Esteban A. Maringolo

observing Pillar execution (PharoLaserGameTutorial)
by Ben Coman May 21, 2014

May 21, 2014

The Pillar documentation [1] says the "@@note xyz..." should produce "Note: xyz..." but that doesn't seem to be happening. This seems to be handled in PRMarkdownWriter>>visitAnnotatedParagraph: but not in PRLaTexWriter. For the PharoLaserGameTutorial I invoke compile.sh. How can I similarly invoke Pillar but have it in GUI mode with a debugger so that I can learn about how Pillar executes? cheers -ben

The topics of your paper can be on all aspect of Smalltalk, theoretical as well as practical. Participants are invited to submit research articles or industrial papers. This year we want to open two different tracks: one research track and one industrial track with less scientific constraints. We expect papers of three kinds: Short position papers describing emerging ideas Long research papers with deeper description of experiments and of research results. Industrial papers with presentation of real and innovative Smalltalk applications; this kind of paper should enlighten why Smalltalk is really appropriate for your application. We will not enforce any length restriction. -------------------- Important Dates -------------------- Submission deadline: June 15, 2014 Notification deadline: July 15, 2014 Workshop : August 19, 2014 All accepted papers will be published in ACM DL (To be confirmed) ------------------- Topics ------------------- We welcome contributions on all aspects, theoretical as well as practical, of Smalltalk related topics such as: Aspect-oriented programming, Design patterns, Experience reports, Frameworks, Implementation, new dialects or languages implemented in Smalltalk, Interaction with other languages, Meta-programming and Meta-modeling, Tools ------------------- Best Paper Award ------------------- To encourage the submission of high-quality papers, the IWST organizing committee is very proud to announce a Best Paper Award for this edition of IWST. We thank Lam Research Corporation for its financial contribution that makes it possible a price for the three best papers: 1000 USD for first place, 600 USD for second place and 400 USD for third place. The ranking will be decided by the program committee during the review process. The awards will be given during the ESUG conference social event. The Best Paper Award will take place only with a minimum of six submissions. Notice also that to be illegible, a paper must be presented at the workshop by one of the author and that the presenting author must be registered at the ESUG conference. ------------------- Publication ------------------- Both submissions and final papers must be prepared using the ACM SIGPLAN 10 point format. Templates for Word and LaTeX are available at http://www.acm.org/sigs/sigplan/authorInformation.htm.

Pharo 3 / osx / Keyboard shortcuts ?
by sergio_101 May 20, 2014

May 20, 2014

i noticed last night that the keyboard shortcuts are a bit different in pharo 3. for instance, to when i mouse over a method, to run the tests, i see there are two keys listed, j, m. i can't seem to figure out which modifiers are required to make this work. i am also not sure how i would go about finding out which functions j and m would perform. run 'this' test, run 'all' tests. any ideas? thanks! -- ---- peace, sergio photographer, journalist, visionary #BitMessage BM-2D8VWUJSS41RFKh1ec83preVabHrnniExa http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

compiling Pillar files locally (for LaserGame book)
by Ben Coman May 20, 2014

May 20, 2014

I've haven't been able to find any instructions on how to compile Pillar files locally. Any pointers? Is TEXLive required for the PDF compilation? Maybe the setup I reported [1] for PBE1 on Windows would be similar? However I now have access to a Mavericks machine. Would that be a better option? What tools would you use to edit with ? (this is my first Mac - something to google for would be useful) I see that [2] runs ./download.sh so perhaps that is all that is required in this case for the LaserGame book?
