Error adding a Class instVar
by Esteban A. Maringolo April 27, 2014

April 27, 2014

I was adding a Class instance variable when I got this, admittedly, funny error. Any clues of why? The class has a Trait (which I plan to remove). Maybe that is causing this? â Esteban A. Maringolo

[Inspiration] Toward a better programming
by Sven Van Caekenberghe April 26, 2014

April 26, 2014

This is a nice write down: http://www.chris-granger.com/2014/03/27/toward-a-better-programming/ with a nice demo of a prototype: https://www.youtube.com/watch?v=L6iUm_Cqx2s Luckily, the horrible C++ code computing standard deviation in the article can be written quite elegantly and directly in Pharo: | input | input := #(2 4 4 4 5 5 7 9). (((input - input average) raisedTo: 2) sum / (input size - 1)) sort. Sven

Modifications to be integrated in Pharo 3.0 VM
by Nicolas Cellier April 26, 2014

April 26, 2014

I think this fix is essential and should be applied before releasing Pharo VM: https://github.com/pharo-project/pharo-vm/pull/31 Those are optionals but would be nice to have: https://github.com/pharo-project/pharo-vm/pull/32 https://github.com/pharo-project/pharo-vm/pull/33 https://github.com/pharo-project/pharo-vm/pull/34 https://github.com/pharo-project/pharo-vm/pull/42 Those can wait but are ready and not dangerous IMO: https://github.com/pharo-project/pharo-vm/pull/37 https://github.com/pharo-project/pharo-vm/pull/39 https://github.com/pharo-project/pharo-vm/pull/40 This one works perfectly for me but failed on the CI server I really wonder why... https://github.com/pharo-project/pharo-vm/pull/41 This one would be nice to have too but does not fully work on my mac. I really fail to understand why... The exact same code in Cog branch works perfectly with same compiler (slightly different options maybe?) I'd be curious to know if all Kernel-Number tests pass when compiled by someone else. https://github.com/pharo-project/pharo-vm/pull/35 And last, the compiler flags should be fixed on MacOSX for bug https://pharo.fogbugz.com/f/cases/11130 Or clang replaced by an older gcc...

Units package access
by Diego Lont April 26, 2014

April 26, 2014

Hi all, I think I have found a bug in Units and would like to correct it. I am using Units, and although it has some quirks (100 kg * (10 m / 1 t) should be 1 m and not 1000 kilogram metres per tonne), it is working well for me. But one point is a problem for me: the â=â is no longer symmetric. The following things should be unequal: 10 kg = 10 s 10 kg = 10 10 = 10 kg But the thing is, that 10 kg = 10 actually returns true. So if someone can give me access I will fix this bug (with a test case). Regards, Diego

Debugging in Production Servers
by askoh April 26, 2014

April 26, 2014

Smalltalk has the capability of allowing live debugging in production servers. How unique is this capability? What other systems allow that? Is there a name for such capability? Can we coin one and market it? What are the pros and cons of having such a capability? All the best, Aik-Siong Koh -- View this message in context: http://forum.world.st/Debugging-in-Production-Servers-tp4756136.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Help needed to compile a fresh Mac Carbon VM
by David T. Lewis April 26, 2014

April 26, 2014

VM hackers and Mac enthusiasts, we need your help. Here is your chance to earn big karma points, along with the grateful admiration of the your peers. What we need: A freshly compiled Mac Carbon VM, just like the Squeak 4.2.5beta1U VM on http://squeakvm.org/mac, but updated to use current VM sources, and to include CameraPlugin and ScratchPlugin. Why we need it: See below. We have a GSOC project mentor who needs to do work on a Mac, who needs to run an image format 6502 (pre-closure) image, and is running into problems related to the outdated Mac VM. We need an update to the Mac VM so that the GSOC project can proceed, and to prevent problems like this for other Mac users who need to be able to run older images (Etoys, Scratch, etc). http://www.google-melange.com/gsoc/project/details/google/gsoc2014/positive… If you have the ability to compile a Mac Carbon VM and make it available to the community, then please speak up. We need your help. (Cross posted to several lists, but discussion should go to vm-dev if possible) Thanks in advance, Dave On Thu, Apr 24, 2014 at 07:55:33PM -0400, Steve Thomas wrote: > David, > > I really appreciate the help and prompt reply. > > I checked and it does work under a previous version of OSX (10.7.2) > > Cheers, > Stephen > > > On Thu, Apr 24, 2014 at 5:01 PM, David T.

CPU usage change on newer OS
by Norbert Hartl April 25, 2014

April 25, 2014

I have a strange effect on my machines. I have a dedicated server and a lot of virtual instances using LXC. The last few days I migrated most projects of our projects from pharo2.0 to pharo3.0. And on the same time the images moved from an ubuntu 12.04. system to a ubuntu 14.04 system. Looking at the top command it appears the images/vms need noticable less CPU or better the tools report less. The monitored overall CPU usage also is much lesser than before. This is not proved by any measurement. Has anyone an idea why this could happen or appear differently? Norbert
