For issues with fixes, we are (still) a bit more relaxed: if it fixes a bug and is deemed to not have too much impact, it is fine. The closer the release comes, the harder we need to apply the âshow stopper onlyâ rule. Marcus

The algorithm is not the same. Macro is 4000 times slower (29/5*700). Some of the navigations/iterators in moose models do too much work and are not just iterating over a simple array. Stephan

I use it for some time but still don't feel it being ok. But then I'm not totally clear what I want. I like to have a notebook probably where text is default and code needs markup (not sure). And I'm not sure if it is a good idea to have one tool here. Maybe the focus on playground and notebook are different. We'll see.

Re: [Pharo-dev] pharo vs. java

by Sven Van Caekenberghe

Some speed difference is to be expected, but the numbers at the end are too extreme. You are mixing micro and macro benchmarks. The micro benchmarks indicate a 10x slowdown, the macro benchmark 700x !

Re: [Pharo-dev] Workspace and GTPlayground menu item

by Sven Van Caekenberghe

I *really* do not understand why people make such a fuss about this. If you open a Playground and never do 'Do it and go', but instead keep on using 'Do it' and 'Inspect it', the second pane never opens and there is hardly any difference. You can keep using it as a notebook. But you do get the much nicer 'Print it' and so many other things. It took me some getting used to as well, but now I hardly notice the difference. > On 16 Mar 2015, at 08:31, Tudor Girba <tudor(a)tudorgirba.com> wrote: > > Why sorry? > > Doru > > On Mon, Mar 16, 2015 at 8:24 AM, Norbert Hartl <norbert(a)hartl.name> wrote: > > > > Am 15.03.2015 um 22:35 schrieb stepharo <stepharo(a)free.fr>: > >> >>> That is great.
