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

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.

Re: [squeak-dev] International text input on X11

Hi Tim, As the VM changes for this matter is in shape (if I'm not mistaken, the plugins.ext has to have ImmX11Plugin), the following image side changes will greatly help the usability for kids in Japan and elsewhere. Can you add those at some point?

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

A $140 pc for running Squeak
by tim Rowledge 05 Jul '16

05 Jul '16

I just got my pi-top CEED (don’t ask me what that stands for…) and after a few minutes setup - inserting the SD card into the provided Pi3, connecting up a couple of cables, inserting the little plastic-magnet ‘feet’ etc - I was up and running. What on earth is a pi-top CEED you ask? Well, think of a small iMac all-in-one with a quite decent 14” lcd and a pi3 inside. Add your own spare mouse/kbd, plug together, insert power plug (psu provided) and press the Magic Button. A moment later you have … what? Err, this is a bit odd looking… ah, escape to a normal desktop and all is well. Run some updating to get stuff sorted out a little (the Scratch version definitely needs updating for example) and all is well. It’s a Pi3 in a nice case with a nice display, a beefy power supply, a neat way of providing space for some add-ons, a proper power switch and a slightly odd OS wrapper. See www.pi-top.com for more details. For US$140! OK, so maybe you have to spend $20 on a mouse & keyboard too. And perhaps you want their speaker unit for another $20. You can get just the lcd/case/pus for $99 if you already have a spare Pi. Given that the Pi 7” touch lcd is $70 on its own, this seems a steal to me. I’m planning to use my three in Scratch classes over the summer. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim All the simple programs have been written, and all the good names taken.

NuScratch source on SqueakMap
by tim Rowledge 05 Jul '16

05 Jul '16

There is now a SM entry pointing to a SqueakSource copy of the current NuScratch as per the Raspberry Pi. It is a rather substantial collection of bug fixes, performance improvements, tidy-ups, speed-ups etc to the original Scratch developed by the MIT team. Project files read and saved are fully compatible with the original system. It runs on modern Squeak systems - I use a 5.0 with updates and it is likely that it won’t run perfectly on anything earlier than say #15852 because some time around then the help balloon stuff changed. I use a Cog/Spur system and make no representation about how well it might work on a non-spur or non-Cog system - I just don’t know and don’t really care. On a RaspberryPi3 it runs large game-like Scratch programs about twice as fast as the original Scratch (a 2.8-ish image on a contemporary interpreter) runs on a modest mac laptop. Or to put it another way, it’s about a gazillion times faster than original Scratch on the same Pi. The licensing remains as per the Scratch Source Code License (google it). You will need to download and unzip a copy of http://download.scratch.mit.edu/source-code/ScratchSkin1.4.zip *before* attempting to install the package. It does *not* include the RaspberryPi specific GPIOServer code; that will appear in a separate package soon. That provides a way to drive al sorts of fun add-on hardware from Scratch - and indeed the lower level driver code for that provides a general Squeak access to the gpio pins and add-ons. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Useful Latin Phrases:- Fac ut vivas. = Get a life.

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

The .changes file should be bound to a single image
by Max Leske 01 Jul '16

01 Jul '16

Hi, Opening the same image twice works fine as long as no writes to the .changes file occur. When both images write to the .changes file however it will be broken for both because the offsets for the changes are wrong. This can lead to lost data and predominantly to invalid method source code, which is a pain with Monticello. I suggest that we implement a kind of lock mechanism to ensure that only one image (the first one opened) can write to the .changes file. I’ve opened an issue for Pharo here: https://pharo.fogbugz.com/f/cases/18635/The-changes-file-should-be-bound-to… Cheers, Max
