About the utility of \\\
by Nicolas Cellier 14 Nov '11

14 Nov '11

\\\ is here to fast up \\ for large integers. It gains roughly a factor 2 (COG VM) by multiplexing quotient and remainder computation in a single primitive. | a b | a := (SmallInteger maxVal raisedTo: 3) + (SmallInteger maxVal*3) + 1. b := (SmallInteger maxVal raisedTo: 2) + 2. {[a \\ b] bench. [a \\\ b] bench.} #('331,000 per second.' '643,000 per second.') Due to high usage of modular arithmetic in cryptography, this is not totally useless. However, I note that this message can also create a noticeable slow down for moderately LargeInteger, (presumably when the quotient is not large) | a b | a := (SmallInteger maxVal raisedTo: 2) + (SmallInteger maxVal*3) + 1. b := SmallInteger maxVal << 4 + 1. {[a \\ b] bench. [a \\\ b] bench.} #('6,670,000 per second.' '797,000 per second.') I wonder if this message is worth at the end... Nicolas

[ANN] New Squeak and SqueakCore
by Edgar J. De Cleene 11 Nov '11

11 Nov '11

Folks here you have the links http://ftp.squeak.org/4.3alpha/Squeak4.3alpha-11777.zip http://ftp.squeak.org/4.3alpha/SqueakCore4.3alpha-11722.zip SqueakCore was build from Squeak4.3alpha-11777. In the procedure I have DNU because Stacks I choose solve commenting ONE LINE and saving Morphic-edc.588.mcz Maybe it¹s time to discuss how SqueakCore should be in the future. The other guys have a bootable ISO and we still in nap mode.... Edgar

I will come and I can give demos or presentations. In the past people tried to get a slot at FOSDEM and it never worked out, so it's great that you managed to get it!

AnObsoleteParagraphEditor subclass? Is that a diffing bug/effect or is this a more serious problem?

Squeak on Google Native Client
by Chris Cunnington 11 Nov '11

11 Nov '11

That's pretty cool. I entered about:flags in the address bar and changed the NativeClient setting to enable. Then I did it for about:plugins. I came back, hit the link, and it said the plugin was not allowed. After flopping around lots of NaCl docs, I managed to make it work by downloading a demo called Ogre, which deposited 50M of stuff on my computer. It's available here: http://www.gonacl.com/dev/demos.html Then I closed and opened Chrome. The flags stayed set and the link ran. Oh, yea. One more thing: wait. It may take a few seconds to appear. It's very cool. I like the bridge a lot. If I recall correctly the Squeak plugin didn't interact with the outside world in any way. What's the story on the PepperPlugin I see referred to in NativeClientBrdige>>#handleMessage? How did you make that? Chris

This is the ParagraphEditor for TextMorphs. ----- In the past, BookMorphs had the ability to have each page be on the server as a .sp SqueakPage file. The index of the book was a .bo file. In text, Cmd-6 had a LinkTo option that linked to a page by its name, or created a new page of that name. It assumed the book was on a server with a file per page. Ted removed that code, and kept a copy on his disk in 'TME-ChngEmphasis.st for .bo .sp'!
