Nuking VM ImageSegment support (was Re: [squeak-dev] Daily Commit Log; System-bf.916)

There's at least 1.5k of generated source for the Spur ImageSegment load and save support, some 2% of the interpreter/primitives source code. That's a lot, and the code is complex and ugly. If it never really worked before IMO we should nuke it asap. If it worked in some fashion perhaps we can schedule its demise for the 6.0 release's VM. What do others think? _,,,^..^,,,_ best, Eliot

Graphing weather data
by tim Rowledge 30 Jun '17

30 Jun '17

Now that I have my Pi based weather station[1] in operation and mounted up on the peak of my garage roof ... … I need to do something with the data it provides. Sadly the code reading the sensors is in Python (for now!) but it sends it as MQTT packets to a mac-mini running the broker. I’m working with Craig on an MQTT client (very early state on http://www.squeaksource.com/@gWFeIvLx-rTHKE2R/Gtrt3pje) to read it but then what? Are there any current projects that will work in squeak5.1/spur that can draw nice graphs? What kind of graphs are good for weather data? Should there be chocolate? I guess I ought to store some amount of collected data so maybe it’s time I got to grips with Magma. I’m interested in all ideas that might lead somewhere fun with this. With those ESP8266 wi-fi enabled sorta-arduino things so cheap and easy to set up there must be a gazillion interesting things that could be monitored and analyzed and graphed and indeed actuated in response; let’s not forget that MQTT works both ways. How about a rain sensor sending a message that its raining (duh) which gets collected and turned into a message to your car to close the sunroof before the velvet seat covers (with painted portrait of Elvis, natch) get wet? Or a strain gauge on your security fence alerting you that something heavier than 20 pounds has climbed over so the remote gatling needs hotting up? tim [1] Pi model A+ with gpio attached interface board for rain bucket, wind speed/direction, outdoor temp/humidity, indoor temp, RTC and USB attached Ethernet interface to POE adaptor. WiFi wasn’t practical due to metal roof. Besides, POE means I can hard-reboot by pulling a plug in my server room :-) -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Strange OpCodes: IIB: Ignore Inquiry and Branch anyway

Hi, The Daily Commit Log mail has not appeared any more since Oct 20. Is this an intentional change or a regression? Best, Jakob

Suggestion for 4.6 - Morphic Designer
by Germán Arduino 27 May '17

27 May '17

Hi Guys: Now that 4.5 is near to be released I want to make a suggestion for 4.6. I think that Squeak have a killer weapon a bit forgotten that should be included in the image, it's Morphic Designer [1] from Hasso Platner Institute [2]. I'm loading it fine from several version already [3] but I think that it should be part of the image in 4.6, for example in menu Tools. This would help to lower the barriers of Squeak to newbies (remember that one of the more criticized aspects from all times is the lack of an UI Builder). And Morphic Designer really rocks and should not be forgot, I think that need to be maintained as part of the official image. What think the community?

Installing Filetree
by Bert Freudenberg 02 May '17

02 May '17

Hi all, Dale has been working on a Squeak version of FileTree, which is a Monticello repository backed not by zip files, but a tree of individual class files that can be versioned using git, svn, etc: https://github.com/dalehenrich/filetree/blob/master/doc/SqueakInstall.md Since I don't like cluttering my image with unrelated things, here's how to load it using just Installer - provided you have an up-to-date trunk image with the fixes I posted today: ======================== "Bootstrap from squeak43 branch in squeaksource3" Installer ss3 project: 'FileTree'; install: 'MonticelloFileTree-Core.squeak43'. "Load from local filetree repository (cloned squeak4.3 branch from github into image folder)" Installer monticello mc: (MCFileTreeRepository directory: (FileDirectory uri: 'filetree/repository/')); install: 'MonticelloFileTree-Core' ======================== If you have an older image without the new fixes, giving an explicit version number for the ss3 bootstrap should make it work (e.g. 'MonticelloFileTree-Core.squeak43-dkh.70'). - Bert -

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?

Morphs can be dropped on main docking bar
by Bernhard Pieber 07 Apr '17

07 Apr '17

I just found out that I can drop morphs on the main docking bar. When I show the docking bar’s context menu, the „accept drops“ checkbox is not clicked, though. Is this a bug or a feature? Bernhard

bouncing source.squeak.org
by Chris Muller 31 Dec '16

31 Dec '16

I just looked at the image and there were bunch of processes hung up on one or another of two critical blocks; although it did not appear that either was part of the call stack of the other. One of them was using a Semaphore instead of a Mutex, so that is suspicious. There were so many, it wasn't evident what the root cause of the issue was, so I decided to bounce the server and will monitor it over the next days to see if the issue returns.

Appears there is a problem accessing one of the MCVersions -- #versionNamed: returned nil, but the calling code didn't expect that. Very helpful would be to know what version it failed on..
