- title toggling doesnât work - doesnât have a usable size - window title not set - dragging doesnât work - disallows selection in one place, allows it somewhere else - menu the same on list title - uses halts directly instead of calling a method on self displaying the action (open a dialog, show a growl)

[ANN] Gravatar for Pharo Smalltalk
by Torsten Bergmann April 23, 2014

April 23, 2014

Hi, The "Gravatar" project is a simple wrapper for the Gravatar API allowing you to get small avatar images for a given registered email address. You can easily access and use it in Pharo. The project is located on STHub at http://smalltalkhub.com/#!/~TorstenBergmann/Gravatar To install just open the Pharo configuration browser and load "Gravatar" from there. You can also install manually, read the docu on the project page. Some examples: Gravatar imageURLFor: 'example(a)mail.com' If you require a different size just evaluate: Gravatar imageURLFor: 'example(a)mail.com' size: 32. If you need the real image you can use Pharos Zinc components suite to get the image form over HTTP and open it on your Pharo desk: |form| form := ZnEasy getJpeg: (self imageURLFor: 'example(a)mail.com'). form asMorph openInWorld In the end it is just a simple class - but I think it may be useful for others too. Thx T.

Monticello Whitewash...
by Eliot Miranda April 23, 2014

April 23, 2014

ugh... after opening a multi-window browser on the Spur classes in the automatically-created VMMaker image I notice once again that Monticello doesn't preserve class organization order on load. grr.... Anyone up to fixing this? -- best, Eliot

One has to collect the relevant packages in a directory (Kernel, Collections & System) and then do e.g. (SpurBootstrapMonticelloPackagePatcher new from: 'image/package-cache' to: 'image/spur-package-cache') patch and then load the packages into the Spur image. When I get my ass in gear this step should be unnecessary since http://source.squeak.org/spur is ready and waiting. So the Spur trunk for Squeak V5.0 will parallel Squeak 4.6 and hopefully supplant it soon enough. The main hold up right now is the combination of the facts that the current compaction algorithm doesn't work well, and image start-up always adds 50% of image size as free space, so the image balloons on each save. I'm finally getting back to working on the compaction algorithm after a very satisfying three weeks working with ClÃ©ment BÃ©ra on Sista. So I hope to have movement on releasing Spur for the 4.6/5.0 development cycle soon. -- best, Eliot

Spur performance report...
by Eliot Miranda April 22, 2014

April 22, 2014

Hi All, I should write a blog post on this, but I can't wait... In recent days I've written a script to build a Cog VMMaker image from Squeak 4.5. See http://www.squeakvm.org/svn/squeak/branches/Cog/image. This has allowed me to run the current Cog VM against Spur side-to-side. To build a Cog VMMaker image on my 2.2GHz Intel Core i7 MacBook Pro using the current Cog VM takes about 2 and a half minutes: McStalker.image$ time oscfvm CogVMMaker.image BuildSqueak45Image.st real 2m30.671s user 2m15.683s sys 0m5.283s To build the equivalent image using Spur takes about 1 and a half minutes: McStalker.image$ time spurcfvm CogVMMaker-spur.image BuildSqueak45Image.st real 1m34.943s user 1m23.666s sys 0m6.810s Comparing: 94.943 - 150.671 / 150.671 * 100 -36.99 83.666 - 135.681 / 135.681 * 100 -38.34 150.671 / 94.943 1.59 135.681 / 83.666 1.62 that's about a -37% speedup, or 1.6x faster. -- best, Eliot

About fonts (again)
by stepharo April 22, 2014

April 22, 2014

Hi when freetype is on do you think that it makes sense to have strikeFont proposed as default fonts? Like it is done right now, I get bitmapVera even if I want to see FreeType fonts. Stef

Milliseconds in DateAndTime or TimeStamp

Hi, I am wondering if there is the possibility to get milliseconds in a TimeStamp. I need to record fine-grained events and second-granularity is not enough. Cheers, Roberto
