We recently agreed that the Squeak epoch was well-defined, i.e. the start of the 20th century in GMT. This is clear if you read the SMalltalk-80 V2 sources. The reason advanced for changing to Unix was that the Squeak epoch is not well-defined. That argument is incorrect. Further, the Squeak epoch is embedded in the VMs, in their answering both seconds and microseconds from the epoch. So there's work involved in getting rid of it. As far as I can see changing it is pointless wasted effort. > > > > The > > argument on the squeak list seemed to be: > > - the squeak epoch has a certain beauty to it, being the turn of the > century > > vs > > - why reinvent the wheel?

I've just done a bit of reading around to familiarize myself with font choice. First of all, there is the question of monospaced versus proportional fonts. It is widely believed that monospaced fonts are better for programming but then Smalltalk is often different and better. I notice that Pharo 1.4 uses proportional fonts and I've never had a problem with that. There is good discussion at [1]. Then there are considerations of technology differences to consider between platforms. * A difference in rendering between Microsoft and Apple [2] * Whether ClearType is available cross platform? Some advantages [3] * Is TrueType available on all platforms? * Will anti-aliasing be always-on? [1] http://programmers.stackexchange.com/questions/5473/does-anyone-prefer-prop… [2] http://www.joelonsoftware.com/items/2007/06/12.html [3] http://blogs.msdn.com/b/fontblog/archive/2005/12/13/503236.aspx Some points against proportional fonts are: 1. Not designed for programming. Distinguishing small-o, cap-o & zero and one, small-i, cap-i, small-l, cap-L is the critical feature. Punctuation is often not very distinctive. A little while ago there was a hack to make the period character larger. Also in Pharo 1.4 cap-i and small-l are hard to distinguish. 2. Alignment of indents. Mainly this is where different developers can use 8, 4 or 2 spaces for fixed tabstops which affects the alignment of text. However searching World > System > Settings for "tab" doesn't show this is configurable, so Pharo seems to sidestep this issue. So I like... * Droid Sans (http://www.google.com/webfonts/specimen/Droid+Sans) Apache License. Steve Matteson. * Ubuntu (http://www.google.com/webfonts/specimen/Ubuntu) (similar to Open Font License) Some points for monospaced fonts are: 3. Some characters are just wider than others. Cramming an 'm' into the space of an 'i' makes it challenging to design a good readable monospace font. 4. Most programmer fonts lack italic and bold - which I think becomes important for Nautilus. * From http://www.codeproject.com/Articles/30040/Font-Survey-42-of-the-Best-Monosp… I like... * Liberation Mono. In particular it seems the clearest of the lot when ClearType is disabled. It deals very well with point (1) above. However while the download page says it is Open Font License the download itself contains only a modified GPL2 license that allows embedding without modification of the font. Steve Matteson. * Droid Sans Mono. Same author. Distinguishable point (1). Strong period. Strong number 1 which matches how it appears in engineering drawings. Apache license. Also consider that people like what they are familiar with, and Android will become fairly widespread. * Dina. Clean without ClearType. Identical even with ClearType. MIT type license. AnonymousPro does also looks good. Disclaimer: I am yet to use these fonts in anger. Just reporting impressions so far. cheers -ben As an aside, even with monospaced fonts there remains an issue with fixed tabstops where new text inserted preceeding a tab stop bumps the tab out of alignment with other vertically aligned text. An very interesting fix for this is "elastic tabstops" [2] [3] [2] http://nickgravgaard.com/elastictabstops/ [3] http://tibleiz.net/code-browser/elastic-tabstops.html

But will it work on Jenkins? Because the update process will want to process the updates one by one so Jenkins will want to load this patches too late (as part of later update). I guess we will need to revert the last updates. -- Pavel On Tue, Jun 12, 2012 at 3:20 AM, Sean P.
