Re: [Pharo-project] [Vm-dev] VM Benchmarks (Was: Re: [squeak-dev] [4.2] - VM <-> image release coordination)

by Camillo Bruni

I am maybe an ignorant here writing like that. I like to see a nice set of benchmarks popping up in Pharo. But did you have a look at my benchmark implementation we use in Pinocchio? Its in the PBenchmark package of the Pinocchio project: MCHttpRepository location: 'http://www.squeaksource.com/p' user: '' password: '' Its a fairly straight forward implementation based on UnitTests... I see several issues in your benchmark implementation which I think are solved much cleaner with my approach: - currently there is one single class with tons of benchmarks in it - no statistically valid output ( just the average doesn't mean anything! see http://dx.doi.org/10.1145/1297105.1297033 for the basic scientific backgrounds) - you interleave model (benchmarks and results) and view (transcript output) which is really evil, there is no way you can ever use this on the command line! so what I suggest, is that you have a look at my implementation and see how we can improve the current situation. m(^_-)m camillo On 2011-03-11, at 15:05, Alexandre Bergel wrote: > I am not sure what you mean with vm benchmarks, but in almost all the tools I am contributing come with some benchmarks (spy, Mondrian, I wrote some benchmarks for Glamour as well).

I am not sure what you mean with vm benchmarks, but in almost all the tools I am contributing come with some benchmarks (spy, Mondrian, I wrote some benchmarks for Glamour as well). Naturally, those are macro benchmarks, which is probably what matter the most.

by Camillo Bruni

Hey, I recently ran into the issue that I cannot use a fixed width/monospace font when working under COG. How can I include a custom font in the image? m(^_-)m camillo

[Pharo-project] Issue 3805 in pharo: PluckedSound does not work in 1.1.1 after "Save and Quit"

by pharo＠googlecode.com

Status: New Owner: ---- New issue 3805 by incongru...(a)gmail.com: PluckedSound does not work in 1.1.1 after "Save and Quit" http://code.google.com/p/pharo/issues/detail?id=3805 Pharo image: Pharo-1.1.1-dev10.09.1, Pharo-1.2 (downloaded Mar 7, 2011) Pharo core version: 1.1.1 Virtual machine used: Squeak 4.2.5beta1U Class browser used (if applicable): OBSystemBrowserAdaptor Steps to reproduce: 1. I load up Pharo-1.1.1-dev10.09.1.image and save it as test.image. 2. I open test.image. 3. I do "PluckedSound default play". The sound plays. 4. I "Save and Quit" 5. I reopen test.image and do "PluckedSound default play" again, but no sound will play. The same is happening for 3 of my friends, 1 is also on OSX and the other two are on windows. I posted this problem on the mailing list and as suggested, I tried the 1.2 image. In the 1.2 image, I am never able to hear a sound, even before saving.

Re: [Pharo-project] how I am supposed to load Spy?

Look on the class side of the class KaiProfiler. In any case, I am now working on a very cool new profiler. It takes a bit of time to pull it out but it will come. Maybe for esug.

Arg. There is no such a problem on the Hudson server: http://hudson.moosetechnology.org/ I tried yesterday, and it works. I will have a look at it on Sunday.
