Nice! :) <http://forum.world.st/file/n4813138/font-importer.png> Two questions: 1. Who does the rendering? Looks kind of irregular... See attachment. 2. Can we move it to the "Tools" package?

New, faster RISC OS Squeak
by Chris Cunnington 01 Oct '16

I get a File 'System:Modules.StreamMan' not found error. I take it from here [1] [2] that StreamMan is short for StreamManager. And that it should be in the sharedsoundbuffer.!System folder. I shift+double clicked and followed !Shared.350.Modules to see StreamMan in this directory. The file appears present but still there is an error.

Time millisecondClockValue (was: The Trunk: Morphic-mt.1080.mcz)

Hacking during the switch from DST to normal time forced the user to wait one hour. Opening images from different time zones did also show this bug. What?! Time millisecondClockValue is supposed to be continuous. I’ll have to admit I didn’t follow the previous discussion too closely, but syncing millisecondClockValue to the wall clock seems like a very bad idea. - Bert -

UTCDateAndTime updated for Squeak 4.6/5.0
by David T. Lewis 08 Jul '16

08 Jul '16

UTCDateAndTime is a UTC based implementation of class DateAndTime with one instance variable representing the magnitude of the point in time, and another representing local time zone offset. I recommend loading with the SAR from http://wiki.squeak.org/squeak/6197, as maintaining this in Montecello is problematic. After the 4.6/5.0 release, I would like to suggest moving Chronology out of the Kernel package into its own package, so that changes in Chronology can be maintained in Montecello without conflicting with the rest of Kernel. Spur notes: The Spur image provides a huge performance when loading this set of changes. There are two steps in the loading process in which all DateAndTime instances need to be #becomed into new instances. This is painfully slow in the traditional image (with or without Cog), and it is amazing fast in Spur. That said, there is a bug in the Spur VM (easily resolved I think) that produces incorrect time values. I'll post note about that on vm-dev. I would not recommend using UTCDateAndTime in Spur yet, other than just to see how amazingly fast it is compared to loading the same thing in a non-Spur image. Dave

Running headless on a Mac
by Frank Shearar 03 Jul '16

03 Jul '16

OK, so I've run out of patience in my flailing around. All I want is to run a headless image on a Mac (so I can unbreak the SqueakTrunk-OSX job, which _used_ to work). How? Do I say "-headless"? ("could not find module vm-display-X11") "-vm-display-null -headless"? ("squeak: could not find any sound driver") "-vm-sound-null -vm-display-null -headless"? ("could not find module vm-sound-null") I don't mind whether I use Cog or Interpreter, as long as I can just get an image running tests. Thanks! frank

Impossible to grab the scroll bar in the Transcript if...
by Eliot Miranda 08 Jun '16

08 Jun '16

Hi All, if the Transcript is open and reasonably full of text and scrolled os that the scroll bar is at the bottom right corner of the window one cannot (at least I cannot) grab the scroll bar to scroll the Transcript contents because the cursor is cooped into window resizing (the window resize cursor is shown). :-( _,,,^..^,,,_ best, Eliot

A Benchmarking tool for the trunk?
by Tim Felgentreff 01 May '16

01 May '16

Hi, We have a proposal for a tool that we think might be useful to have in trunk. We spent some time pulling together benchmarks from various sources (papers, the mailinglist, projects on squeaksource, ...) and combining them with an extended version of Stefan Marr's implementation of a benchmarking framework SMark. The tool and framework are modeled after SUnit, and include different execution suites and code to figure out confidence variations over multiple runs and such. Also, it draws graphs over multiple runs so you can look at things like warmup and GC behavior, and see how much time is spent doing incremental GCs and full GCs vs plain execution. As a part of this I fixed the EPS export so these graphs can be exported in a scalable format. Here is a picture of the tool: https://dl.dropboxusercontent.com/u/26242153/screenshot.jpg As I said, it's modeled after TestRunner and SUnit, benchmarks subclass from the "Benchmark" class, any method starting with "bench" is a benchmark, and you can have setUp and tearDown methods as usual. By default the benchmarks are run under an Autosize runner that re-executes each benchmark until the combined runtime reaches 600ms (to smooth out any noise). Beyond that, you can specify a number of iterations that the runner will re-do that to see multiple averaged runs. The graph shows the execution times split between running code (gray) incremental GCs (yellow) and full GCs (red). There are popups and you can scroll to zoom in and out. There is also a history of benchmark runs stored on the class side of benchmark classes for later reference. The code currently lives here: http://www.hpi.uni-potsdam.de/hirschfeld/squeaksource/BenchmarkRunner Considering we are every so often discussing benchmark results here, I think it might be useful to share an execution framework for those. cheers, Tim
