Re: [Pharo-dev] Pharo 4 Beta, first impressions

by Esteban Lorenzano

lot of time ago we decided *not* to pretend imitate any OS L&F, because is first a lot of work, and second a lose of time: they do not fit, and if you want to make them fit for real you need to spend *really* much time there (and you probably will fail anyway). Themes remained there without being maintained and they started to break. As no one uses it, no one noticed :) So we started to remove them. Nowâ¦ I would like to not just remove anything, but to move them to a graveyard, where it can be revived by any necromancer who wants to give them a try. We need to improve there. w2k theme wasâ¦ old. Didnât fit with any current L&F, not windows either. So, if you used the w2k theme just because of the icons (and alsoâ¦ I have to say it: windows and mac *is not* the same: windows is plenty of home-made L&F that does not respect any design ruleâ¦ mac is not like that). But well, coming back: if you want that old theme just for the icons, I just recommend you to take current theme and modify it to have the icons where you want (should not be so difficult). In the long term, it will be a lot more maintainable :) cheers, Esteban > On 03 Apr 2015, at 16:07, Sven Van Caekenberghe <sven(a)stfx.eu> wrote: > > >> On 03 Apr 2015, at 15:57, Benoit St-Jean via Pharo-dev <pharo-dev(a)lists.pharo.org> wrote: >> >> >> Date: 3 Apr 2015 15:53:56 CEST >> From: Benoit St-Jean <bstjean(a)yahoo.com> >> Reply-To: Benoit St-Jean <bstjean(a)yahoo.com> >> To: Pharo Development List <pharo-dev(a)lists.pharo.org> >> Subject: Re: [Pharo-dev] Pharo 4 Beta, first impressions >> >> >> Kilon, >> >> I can perfectly understand that "not everything has to be in the image" and that, ultimately, someone has to maintain that code.

There is ThirtyTwoBitRegister â I represent a 32-bit register. An instance of me can hold any non-negative integer in the range [0..(2^32 - 1)]. Operations are performed on my contents in place, like a hardware register, and results are always modulo 2^32. This class is primarily meant for use by the SecureHashAlgorithm class.

If you want to argue about usage, this is probably more appropriate http://strawpoll.me/4001583/r (though Linux numbers are in reallity somewhat lower due to desktop+server) The bottom line is: nobody (from ~third of Pharo users) really cared until now so the options I see: 1. open an issue in Pharo issue tracker 2. a) write it yourself, or 2. b) ask someone who is interested in themes to write it If nothing fundamental changed in theming in Pharo 4, than moving the buttons around should take an evening with bottle of beer at most. If you want it in the default theme but customizable, that may take more, but it would be interesting. If you want the whole Windows theme than that may be a bit more.

VM and .sources in separate dirs question

by Dmitri Zagidulin

While editing an Updated Pharo by Example chapter, I came across this: "The '.sources' file and the VM can be read-only, and can be shared between different users. All of these files can be placed in the same directory, but it is also possible to put the Virtual Machine and sources file in separate directory where everyone has access to them." Is this true, that you can keep the VM and .sources in different directories? How do you tell the VM where to locate the sources? I assume it's some sort of commandline parameter?

Ways to do 32-bit arithmetics?

by Stefan Marr

Hi: I am porting some benchmarks to Pharo, which rely on a deterministic random number generator that uses 32 bit values. In order to have properly comparable results across platforms, it needs to generated the same sequence of numbers. So, I am looking for efficient ways to implement it, any ideas? I am a little at a loss, with SmallInts and Long Ints, how to get the proper 32-bit values, and how to apply the correct shifts, especially the right shift can be problematic. Code examples below. Thanks Stefan In Java it looks like this: private static int seed; // Robert Jenkins' 32 bit integer hash function. public static int random() { seed = ((seed + 0x7ed55d16) + (seed << 12)) & 0xffffffff; seed = ((seed ^ 0xc761c23c) ^ (seed >>> 19)) & 0xffffffff; seed = ((seed + 0x165667b1) + (seed << 5)) & 0xffffffff; seed = ((seed + 0xd3a2646c) ^ (seed << 9)) & 0xffffffff; seed = ((seed + 0xfd7046c5) + (seed << 3)) & 0xffffffff; seed = ((seed ^ 0xb55a4f09) ^ (seed >>> 16)) & 0xffffffff; return seed; } In SOM Smalltalk, it looks like this: JenkinsRandom = ( ---- | seed | seed: val = ( seed := val ) "Robert Jenkins' 32 bit integer hash function." random = ( seed := ((seed + 2127912214 "0x7ed55d16") + (seed as32BitUnsignedValue << 12) as32BitSignedValue) as32BitSignedValue. seed := ((seed bitXor: 3345072700 "0xc761c23c") bitXor: (seed as32BitUnsignedValue >>> 19)) as32BitSignedValue. seed := ((seed + 374761393 "0x165667B1") + (seed as32BitUnsignedValue << 5) as32BitSignedValue) as32BitSignedValue. seed := ((seed + 3550635116 "0xd3a2646c") bitXor: (seed as32BitUnsignedValue << 9) as32BitSignedValue) as32BitSignedValue. seed := ((seed + 4251993797 "0xfd7046c5") + (seed as32BitUnsignedValue << 3) as32BitSignedValue) as32BitSignedValue. seed := ((seed bitXor: 3042594569 "0xb55a4f09") bitXor: (seed as32BitUnsignedValue >>> 16)) as32BitSignedValue. ^ seed ) ) -- Stefan Marr INRIA Lille - Nord Europe http://stefan-marr.de/research/
