Talking about these things here makes me a bit self-conscious, as I like to describe things in historical terms, while all the players are right here. But silence teaches me nothing, so... Your site is invaluable to anybody interested in Tweak, which includes anybody who has ever had doubts about Morphic. http://tweakproject.org Chris

Unicode strings, benchmarks
by Janko Mivšek 01 Jan '11

01 Jan '11

Hi Squeakers, I already extended String with TwoByteString and did a "scaling" with auto conversion to wider string when a wider character is put into a string. So far so good and this already works in Aida/Web. I also did a bit better UTF8 conversion but is only 25-80% faster that existing one in UTF8TextConverter. To prepare for even better results, I made a benchmark, which measure conversion time for English, French, Slovenian, Russian and Chinese 2500 characters long text. It measure 100 conversions which accumulates to 250K characters of text. Here are results in VW, Squeak with old UTF8 converter and a new one: VW old new english 30 313 248 ByteString, pure ASCII french 32 323 251 ByteString, ISO8859-1 (Latin 1) slovenian 48 578 480 TwoByteString Latin 2 russian 112 1306 720 TwoByteString Cyrillic chinese 107 1544 3825 TwoByteString Notice an exceptional 10x VW performance comparing to Squeak, and they do all encodings in plain Smalltalk! No primitives! So how come that Squeak is so slow here? Above benchmark was done on Squeak 3.9 on Suse Linux 10.1, P3.2GHz.

[4.2] Inbox status
by Chris Muller 01 Jan '11

01 Jan '11

I went through Squeak's Inbox today and cleared out some of my own old stuff and reviewed some of the contributions from others. I encourage other core developers to make a similar final pass on the Inbox. Bottom line: Unless I've overlooked some final crucial fix, I don't intend to integrate any of the remaining Inbox items into 4.2. Everything I looked at were "enhancements" which can be lobbied-for and integrated into 4.3. 4.2 will not be a perfect release, but our development does not stop. My focus at this time is on getting it out the door so we will have a new baseline and can start talking about things in the context of "4.3". - Chris

WeakArray>>isFinalizationSupported
by Sean P. DeNigris 31 Dec '10

31 Dec '10

As I port code from Sophie back to Squeak, I keep running into WeakArray>>isFinalizationSupported calls. Can I safely remove these checks? The method doesn't exist in Pharo and it'd be easiest for interoperability. Thanks.

SqueakSource: Reply-To address?
by Frank Shearar 31 Dec '10

31 Dec '10

Hi, I'm adding a new project (http://www.squeaksource.com/Zippers.html) to SqueakSource, and some new options puzzle me. What's the Reply-To address for? I know what they're for in emails, so I _guess_ that it's the Reply-To address in commit mails generated by the project? Second, the checkbox "Receive commit notifications by email" means that those subscribed to the project (one of Administrators, Developers, Guests) receive notifications whenever someone commits to the project? Is it possible to subscribe to a project without being an member of the project in some way? frank
