This is what I get during the update: ThirtyTwoBitRegister doesNotUnderstand: #load: This is triggered by: MD5NonPrimitive>>initialize "MD5 initialize" "Obscure fact: those magic hex numbers that are hard to type in correctly are actually the result of a simple trigonometric function and are therefore easier to compute than proofread.

Is this related to load order or something? Also mind the previously banned underscores... Nicolas

[Pharo-project] How important is ANSI Smalltalk / speeding up ASCII/Latin1/Unicode I/O
by Dave Mason July 23, 2009

July 23, 2009

I have been wondering about ways to speed up character-set conversions, and related I/O as mentioned in the recent email about MultiByteFileStream. However this change might break parts of the ANSI Smalltalk hierarchy - particularly around String. So my question is, how important is ANSI compatibility? Squeak? GNU Smalltalk? VW? VA? On a related question, how common is it to subclass String? Would it be a mess if it were its own little hierarchy of classes? ../Dave

[Pharo-project] The Pharo Toolset Guide (request)
by Esteban A. Maringolo July 23, 2009

July 23, 2009

Hi, As I told, I'm new to this squeak/pharo world, particulary in relation with its toolset. I'm developing, and by now I was using fileOut/fileIn to manage, save, version, etc my codebase. I would like to know how to create a Monticello repository to host my projects, how to create a package for them, etc. I know there are many versions around, and don't know which is the one in use in the latest Pharo core. Is there a "terse guide" to get a smalltalker coming from other smalltalk to understand the phylosophy behind the Pharo tools, and how to use them? Besides http://www.wiresong.ca/Monticello/UserManual/, is there any other resource I should be aware to learn the mentioned above? Best regards, Esteban A. Maringolo

None of these are Windows VM issues. The problem referred to above is simply that someone was using a year-old 3.10.2 VM and tried to call IPv6 primitives (the debug log shows that clearly). The IPv6 prims are not available in these old VMs. The discussion below is similarly confused. The Windows VM does return fully qualified names if your network environment is set up properly. Usually, the domain name is set by DHCP, but you can set it manually in the advanced network settings (on XP it's under network, properties, TCP/IP, advanced, append dns suffixes; Vista will surely differ).
