Crash.dmp not created on windows

by Blondeau Vincent

Hello, Since the release of the spur vm, the crash dump file (crash.dmp) is not generated when the image crashes under Windows (7 especially). Now, I have an image I cannot use because its crashed at startup and I cannot report a bug to VM developers in the purpose to resolve the crash. An issue on this has been opened almost for one year: https://pharo.fogbugz.com/f/cases/17506/when-an-Image-crashes-a-crash-dmp-f… Does the creation of this crash.dmp is planned?

Hi, Everything is in the subject :) Tomorrow we will handle a new TechTalk, this time to talk about Iceberg, the new SCM tool for Pharo. Since Nico will to also a âtourâ about what is implemented and how we expect the tool will be used, this time we will try to stream a public stream so people can watchâ¦ and participation, questions, etc. will be handled through discord, as usual. I will send links to both video and discord as soon as we have it :) cheers, Esteban

Re: [Pharo-dev] About traits

by tesonep＠gmail.com

Hi, my implementation is in https://github.com/tesonep/pharo-talents . It does not have enough documentation, although the tests have working examples. I have as an objective of this week write more documentation.

Re: [Pharo-dev] protocol pane "no messages" Re: [Pharo-users] setter method

I will add that I doubt that any filetree repository (or at least its metadata-less versions) repository is capable of remembering an empty protocol. 2016-12-10 20:27 GMT+01:00 phil(a)highoctane.be <phil(a)highoctane.be>: > Hi Ben, > > Yes and no. > Because you can add a protocol right away without any method and end up in > my layout. > > Pedantically yours, > Phil > > On Sat, Dec 10, 2016 at 2:17 PM, Ben Coman <btc(a)openinworld.com> wrote: > >> Nope.

Great works ! I will add some contents for Actalk chapter. BTW I update a little bit the PolyMath book. There was some sections missing.

A little prototype kernel in 9 methods :)

by stepharong

Hi guys I'm thinking to package some of my language design knowledge in a kind of book. Probably to be used to give a lecture on OOP languages. I have class-based reflective kernel. This is several years that I was thinking about prototype kernels and I decided to relax and implement one for fun over the week-end. I will probably look at mixins, traits, talents, split objects in the future. Since I cannot compile the book on jenkins, I join the pdf. Stef PS: I will finish Pharo by example now and focus on Learning OOP with Pharo. -- Using Opera's mail client: http://www.opera.com/mail/
