Re: 3.7 moving to beta tomorrowish

Yoshiki, =============================== Ah, this is... I don't know what to say... =============================== You said it well. =============================== Second, let's clarify that the external representation and the internal representation are different beast. My stuff mainly uses the UTF-8 for the external representation. As long as your code is mainly written in pure ASCII plus a few other characters such as up arrow and left arrow, the difference in size is just ignorable. =============================== It seems wise to sit back and let you solve the back arrow problem. =============================== For the internal representation, my stuff use 8-bit per character representation for a String that solely contains latin1 characters. For those Strings that contains non-latin1 chars, it actually uses 32-bit representation. It is similar to the SmallInteger and LargeInteger implicit conversion and the user shouldn't have to care about the difference. The typical memory footprint surely will go up a bit, but as you can imagine, not much. =============================== That sounds great. Thanks for the explanation. Bill Wilhelm K.

Romain, ========================== Concerning your project of allowing the ability to switch between underscore and := (which I'd really like to be done ...), I just found that there is a preference which is "ansiAssignmentOperatorWhenPrettyPrinting", so if in case you didn't know, that might help you (browing the senders of #ansi... might help you locating places to change). ========================== Coincidentally, I ran across that option shortly before your post, but I (sad to say) did not recognize it as being useful in this context. I was more distressed to recall that color syntax highlighting (which I like) seems to be tied to pretty printing/formatting (which I do not generally like). It sounds as though Yoshiki is closing on a solution, and it's probably best to let him work. There is one potential caveat, which will give me an opportunity to display the true nature of my ignorance about unicode :) An overly blunt way to look at unicode is that it offers us an opportunity to double the storage requirements for all of our text. In fact, one device that I have encountered uses "unicode" (it likely predates the standards), and ends up doing precisely that - each character it sends is followed by a gratuitous zero, in a world where every byte truly counts thanks to bandwidth restrictions. I understand the value of unicode, and want Squeak to embrace it. However, is unicode something that many of us would want to disable most of the time? I ask because, if true, we might want another solution to the underscore/:= collision. Bill Wilhelm K.

Apologies if this topic's been covered before. I tried to upgrade Monticello from version 123 to 146, and got this walkback. How do I work around this? frank

So, does it run Squeak? It's supposed to have linux at the core. I'd love a cheap handheld. cheers bruce ====forwarded====

[ENH][FIX] DateTimeFactoredPrint-nk v2 (more tests, speedup for BFAV)
by ned＠squeakland.org 30 Mar '04

30 Mar '04

"Change Set: DateTimeFactoredPrint-nk Date: 30 March 2004 Author: Ned Konz Makes all the Kernel-Chronology-Tests test cases pass in a 5816 image. This requires the following prerequisites: accurateDateAndTimeNowV2-avi (21 February, Avi Bryant) testChronologyHours12-brp (12 March, Brent Pinkney) chronologyTimeStampNow-brp (12 March, Brent Pinkney) v2 (30 March 2004): - sped up DateAndTime comparisons considerably (very noticeable on BFAV) - sped up DateAndTime creation (ticks:offset:) - added default initialization of Duration to 0 - sped up Duration class>>seconds: and Duration class>>zero - fixed broken test cases - added timezone saving/restoring to test cases - removed linefeeds - removed some assumptions about strict monotonicity of Timestamps from test cases (which is appropriate for this version of the Timestamp code, but may need to be revisited if the Timestamp logic is changed). v1 (12 March 2004): - Factors DateAndTime>>printOn: into separate parts for easier use. - Omits leading space by default in printOn: - Adds alternative printOn:withLeadingSpace: - Fixes DateAndTime test cases - Omits recompilation of Deprecated>>defaultAction from test cases (why was this done?) - Fixes the spelling of 'Greenwich' - Adds a class comment to Date - Changes TimeZone default to report UTC rather than GMT "

I'm a big fan of the Network Audio System, the oldest, and most featureful network sound system for Unix. You can even buy NEC X terminals that have this built into them. NAS is mature and it's well engineered, and I do not at all understand why the Linux guys are not jumping all over it. I also don't see why esd exists at all; nas was mature when the esd project began. Anyway, you do not have to go with the herd. You can use nasd, and then run Squeak/Unix with the NAS sound driver. You can run legacy OSS programs using "audioss" (available in Debian's apt repos), and you can run silly ESD programs by running "esd" itself under audiooss. > I get "sound: /dev/dsp: Device or resource busy" on the terminal when > I try to use sound. Seems like the classic problem where both want to > own the sound device; I don't know if there's an easy solution. Incidentally, you may want to try running "fuser -va /dev/dsp" as root in order to see who is using the audio device. I'm guessing it's esd or artsd, but Squeak can't talk to either of those daemons. I've looked into implementing support for each of them on multiple occasions, but given up on it every time. esd doesn't support what Squeak needs, and I had trouble finding a comprehensible way to talk to artsd from a simple C program. -Lex

All squeak map servers down?
by Peter William Lount 30 Mar '04

30 Mar '04

Hi, This morning when I try to update my squeak map from the net it reports that all the squeak maps are down. It's list of sm's are map1.squeakfoundation.org map2.squeakfoundation.org map.squeak.org anakin.bluefish.se Is this list up to date, or do I have to update sources first? Oh, I try that and it loads many updates untill it's working on 'Loading 5727SmaCC-RuntimeSM-md...' at which point it's trying to execute this doit: DoIt ^ SMSqueakMap default loadUpdates; installPackageWithId: '2d9c9a9e-ce66-4e82-a785-ca7d43d9b4c4' autoVersion: '2' which fails in "SqueakMap class>findServers" since the squeakmaps are off-line. Any ideas? Wait till they come back online? Are there some other urls for squeakmap backups? Cheers, Peter

Can't ping SM from a 5816 image, works from older images
by Doug Way 30 Mar '04

30 Mar '04

SMSqueakMap pingServer: 'map1.squeakfoundation.org' At the moment, this returns false with a fresh 3.7alpha-5816 image (on Mac OS X). However, with a 3.7alpha-5707 image or a 3.6 image, it returns true. This means I can't easily use SqueakMap at the moment... (although I can download packages in an older image and then load them in the new image.) - Doug
