Is lazy evaluation of infinite series possible?
by Erisa June 6, 2016

June 6, 2016

I am just learning Pharo (taking the MOOC actually!) and am wondering whether it is possible to model formal power series. I have done this in Haskell quite easily and efficiently, but struggled to do it in Python without real success. It requires one to perform operations on an infinite stream (such as multiplying two infinite power series). One then only evaluates the terms as they are needed, i.e., lazily. Any thoughts? -- View this message in context: http://forum.world.st/Is-lazy-evaluation-of-infinite-series-possible-tp4897… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Pharo 5 accented chars bug/regression
by rausm June 6, 2016

June 6, 2016

Hi, seems like Pharo 5 (Win 7 64bit) has a regression / new bug with same symptoms as described in: http://lists.pharo.org/pipermail/pharo-dev_lists.pharo.org/2010-May/027180.… Nearly all accented characters work ok. Seems like any character can be pasted in and displays correctly, but any attempt to directly enter "Ä" or "Ä" ("caron" + c / e) fails. [I have a hunch there was some easy fix; either my memory plays tricks on me, or google can't find it] Thanks for any tip, M.R. -- View this message in context: http://forum.world.st/Pharo-5-accented-chars-bug-regression-tp4898863.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

VOMongoError: Lazy reference not found CatalogRepository: OID(67173037322134959457277313026) Maybe some aggressive cleanup? Tommaso

problem getting moose
by Ben Coman June 5, 2016

June 5, 2016

I wanted to try out Peter's XMI Analyser with Roassal and went to download Moose but had a couple of problems. First try... In the Launcher under Common Tools, I downloaded and Moose 5.1(stable) fine, but it is Pharo 4, so tried to download Moose 6.0(beta) -- but got a problem - big pause, no progress bars, the later ZipArchive reporting "Error: can't find EOCD position" Second try... The web site advises for Moose 6.0 to download the Moose code in a Pharo 5.0 image per... Gofer new smalltalkhubUser: 'Moose' project: 'Moose'; configuration; loadDevelopment. Doing that in build 50760 download with the Launcher produced... Could not resolve: Phexample [Phexample-NikoSchwarz.57] in /home/ben/.local/share/Pharo/images/Moose6-50760/package-cache http://www.squeaksource.com/Moose ERROR: 'GoferRepositoryError: Could not access http://www.squeaksource.com/phexample: ZnInvalidUTF8: Illegal leading byte for utf-8 encoding' Could someone check if they see the same, or maybe my Internet is flakey atm? (preferably someone who doesn't normally use Moose to avoid package cache differences) cheers -ben

Pharo 5 hanging and crashing
by Gerry Weaver June 5, 2016

June 5, 2016

Hello All, I am new to Pharo and Smalltalk in general. I have been experimenting with Pharo 5 trying to get acquainted with the environment and the language. I have been having some issues with the image hanging and crashing. This happens when trying code in the Play Ground and especially when stepping through code in the debugger. Has anyone had similar problems? Should I be using Pharo 4 instead? I have been testing Pharo on Windows 8 64bit and Ubuntu 14.04 64bit. Could this be a 64bit issue? Thanks

Pharo MOOC: A propossed change on factorial
by Offray Vladimir Luna CÃ¡rdenas June 5, 2016

June 5, 2016

Hi all, I'm advancing on the Pharo MOOC trying to catch the rest of the people. It has been a really interesting learning experience. Now I'm making the Block lesson on week 2 and I have found the factorial example with its code. With the quality assistant It noticed no spaces at the beginning or end of the blocks and I'm also wondering how the factorial definition could be changed to give a more friendly message for non integer positive numbers, similar to the one it gives for negative number. For example, if I put "1.5 factorial" I get the "MNU: BoxedFloat64>>factorial". What could the strategy in this case? Cheers, Offray

the impact of moldability
by Tudor Girba June 4, 2016

June 4, 2016

Hi, There were a couple of emails in the recent period that questioned the usefulness of moldability (the ability of developers to customize their tools deeply and inexpensively). More specifically, the question was about the moldability of the GTDebugger. I put together a couple of thoughts of why we think that moldability is actually a competitive advantage: http://www.humane-assessment.com/blog/the-impact-of-moldability/ Please read it and provide feedback. Cheers, Doru -- www.tudorgirba.com www.feenk.com "Reasonable is what we are accustomed with."
