Re: [Pharo-project] Proposal: adding 261 named colors

by Johan Fabry

Yes there are some fun names in there: ice, yelowish, midnight, barney. Also some very 'human-excreta-related' ones: puke, vomit, poo, booger, ... But I chose not to pass a watch-out-for-the-children filter.

Now I am happy to say that thanks to the XKCD color survey I was able to improve on this. I can now use 261 named colors thanks to a XKCDColor class, and I'd like to share the code, ideally to be included into Pharo.

Yes if it doesn't make it in Pharo, it would be great that it gets in Moose. Stef, you closed the bug, does this mean it will be integrated ?

Re: [Pharo-project] some patterns I would like to **kill**

by Schwab,Wilhelm K

If I understand you, you took things normally stored in instance variables, and (redundantly?) stored them as properties, right? ________________________________________ From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] On Behalf Of Igor Stasenko [siguctua(a)gmail.com] Sent: Saturday, October 23, 2010 10:47 PM To: Pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] some patterns I would like to **kill** On 23 October 2010 21:47, Schwab,Wilhelm K <bschwab(a)anest.ufl.edu> wrote: > Hey, I want some credit here - for coming to Squeak's possible defense :) > > All I am saying is that there is a possible space/speed tradeoff with a twist. There was a fair amount written about these decisions, which is why I know anything at all about them. Adding an instance variable for a rarely used sub-morph of a widely-instantiated morph might be an opportunity to fail to learn from history. Most likely, the patterns Stef has noticed are simply mis-uses of sparse storage. The best way to proceed would be to find an example of it that has many instances in the image, profile, fix, and profile again to see if the fix hurts performance (or perhaps helps it). The usual caveats about benchmarking being really hard to do well apply, of course. > I did some experiment(s) with Morphic, placing many morph aspects into properties dictioary (such as color, border, borderwidth etc), and these values are used in rendering all the time.

Morphs were designed to be usable in large numbers, and one might argue (playing Devil's Advocate here) that lookups are cheaper than the additional gc load. An instance variable could also cache stale information.
