#flash UI output
by Chris Muller 28 Dec '15

Hi Marcel, one thing I miss is the flash associated with search-string not-found. When I press Command+g and its not found, I want it to flash, not change my selection. In another example, I'm working on phasing out an instVar, I browse references to it and eliminate the references one-by-one. Now before closing the window, I used to be able to arrow though and simply make sure I get a flash on every press. Now it doesn't flash so I really have to look closely..

I just wanted to post some novel news I heard over Christmas. My 11 year old nephew has used Scratch in school! Seeing as how I gave him a Pi 2 for his gift, he's going to get lots of hands on. My family was surprised & excited to hear that it was based in Squeak, knowing my predilections. Rockin it! Cheers, robert

Preferences search broken

Desperately trying to turn off 'Sort Message Categories Alphabetically' but the Preferences browser search isn't working. I tried searching for "sort", "alph", "categor". Clearly, something is broken with Preferences search..

True, though the Pi Raspbian does include the full VM setup (currently a Cog Spur 34xx level vm), which means that a fairly small package of image/change/sources/tutorials/examples/support files is al lthat would be needed. Oh, wait, we don’t have a well thought out tutorial world. By far the biggest problem would be raising money I fear. The foundation can’t offer any because it basically doesn’t have any. It’s just as well the SFC provide free hosting because we’d not be able to pay for commercial support. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Time to start the War on Errorism before stupidity finally gets us.

Note that for Pharo there is a project from Mike Filonov (owner of pharocloud.com) which was initially called "PharoNOS". It is also based on TinyCore Linux, here x86 based directly booting into Pharo. A description and an downloadable ISO is available on [1]. Runs fine on VirtualBox. >From the name often people thought it was a project similar to "SqueakNOS" (but SqueakNOS boots into Squeak and needed no Linux or other underneath as even the drivers were written in Smalltalk). I guess therefore Mike renamed the project to "Pharocloud OS" now, he also made the build scripts available on [2]. I also did some experiments with Pharo on the Pi - described in an article on [3]. The result was similar: directly booting into the Pharo environment/ a Smalltalk application - but on the Pi. There is Raspbian underneath. A video is available on [4]. However: if there is now some interest in having a fast and direct Squeak/Pharo booting on the Pi maybe this could be a shared effort between both communities as well. Beside squeak-dev I therefore CC the pharo-dev mailinglist as well. Bye T.

don't know where to post this, but I think some of you may be or was involved in this projects or know someone how did: smalltalk.org -> Error The requested URL could not be retrieved www.opencobalt.org -> This website is temporarily unavailable, please try again later. http://www.swazoo.org -> "This domain has expired. If you owned this domain, ...." http://www.iliadproject.org -> Does not look like a web frame work :) http://gjallar.se/ -> does not like like an issue management system. wikipedia links to smalltalk.org the other links are from http://www.world.st/try/projects and squeak.org has a link to opencobalt.org

It boots in 12 seconds, from power on to login prompt, on a Pi 2. That gives you wifi plus an openssh server. It would probably add a few seconds to get a graphical shell running, which it also includes. - Jon

A Suggested Promotion

I have a suggestion for future Smalltalk advocates... The advent of Pi Zero last month is an interesting opportunity. This is a very, very cheap Raspberry Pi. Anyone can afford it. I'm thinking of kids, in particular. What if we could get kids to delve into Squeak or Pharo (Squeak is better optimized for Raspberry Pi) via the Pi Zero? A competition could be set up in various countries, such as Canada, Britain, Australia, Japan, etc., where the best student submission for a Smalltalk-based Pi Zero application would win a small scholarship prize (say, $500). A panel of judges in each country would decide the winner. The contest would be much less ambitious than my now-defunct Canadian Smalltalk Competition <https://www.kickstarter.com/projects/1520902870/canadian-smalltalk-competit…> (CSC). Less control (no real need to prevent cheating). Easier to raise the prize money. The nice thing is that it would be a multi-national promotion (it's tough getting a national school competition like CSC going in other countries). Of course, because it's less ambitious, we can expect to reach fewer kids. Instead of thousands, probably more like hundreds. I could be totally wrong on this; I could be totally surprised! I might even come out of retirement <https://medium.com/@richardeng/today-is-the-first-anniversary-of-smalltalk-…> to offer some creative services (eg, promotional graphics, websites, etc.). 😁 Anyway, it was just an interesting thought I had. Don't know if it stands up to scrutiny. Cheers, Richard
