Question about ImageMorph
by Manas Dadarkar 08 Aug '06

08 Aug '06

Hi, I have a ImageMorph that I am displaying at the top of another ImageMorph. The top ImageMorph has a white background. Is there any way I can make the background of the top ImageMorph transparent so that the ImageMorph at the back is also visibile? I tried using beTransparant: true but that didn't help. Thanks, -Manas

IBM PC and open-source
by Brad Fuller 07 Aug '06

07 Aug '06

Hey All, I created a blog wondering that if open-source was popular when the IBM PC was introduced (25 years ago this week), would the PC look/be any different today, and if so, how. I mentioned Xerox PARC in the blog, but I don't know if there was any interaction between PARC and IBM (reportedly not, but that's just what I read.) If anyone has insights or knowledge of the time, I sure would like to read your thoughts by posting on the blog (no, I don't get any $$ from this!) While I don't believe one could consider the technology at PARC open source, I have read and heard that PARC did try and evangelize Smalltalk to push it out of the lab to propagate its use. Certainly it's predecessor Squeak can, for all practical purpose (ignoring the licensing issues), be considered open source. Here's the link to the blog: http://www.oreillynet.com/digitalmedia/blog/2006/08/open_source_in_1981_the… thanks for your insights! -- brad fuller

by Masashi UMEZAWA 06 Aug '06

06 Aug '06

Hi, I wrote a simple OpenDHT (http://www.opendht.org/) client. http://map.squeak.org/account/package/8c833bda-8157-4af8-a252-1c78be34f0c9 You can also access local Bamboo DHT (http://bamboo-dht.org/), and Overlay Weaver (http://overlayweaver.sourceforge.net/). Sample code: client := OpenDHTClient new. client at: 'key1' add: 'value1'. "put" return := client at: 'key1'. "get: returns #('value1')" Enjoy! -- [:masashi | ^umezawa]

[SqNOS] New Article: Building, changing, booting and installing.
by Gerardo Richarte 04 Aug '06

04 Aug '06

*Posted 4 Aug 2006 by gera <http://people.squeakfoundation.org/person/gera/>* (Journeyer) To roll your own version of SqueakNOS, either changing the native side or the .image side, you need to know how to rebuild and boot it. This process should be as easy and fast as possible. This article will explain the building process and the boot process, describing how to rebuild everything from scratch, how to create a new .iso image, and how to use GRUB to boot SqueakNOS from a fat/vfat, NTFS, ext2/3 or other file system, from either a harddisk or USB disk. http://people.squeakfoundation.org/article/61.html Index: *Quickly rebuilding and trying *Booting from other than a CD **General GRUB instructions *Chaining GRUB with Windows 2000/XP/2003 bootloader* *Chaining GRUB with LILO **Chaining GRUB with SYSLINUX **Chaining GRUB with another GRUB **Chaining GRUB with DOS or Windows 9x/ME **Installing SqueakNOS' GRUB as bootloader **Booting SqueakNOS from a USB disk* *Last notes on using GRUB **SqueakNOS components * *What now? * * enjoy as much as possible! gera * *PS: I accidentally posted a draft version of the article a few days ago, now, thanks to Ken Causey I was able to replace it with this finished version. *

Re: Anybody out there in Vietnam?
by Doan Nhu Tung 04 Aug '06

04 Aug '06

Hi Georg, I'm from Vietnam. I did a Smalltalk course when I was in EMOOSE at Ecole des Mines de Nantes, France; and I'm in love with it ever since. While I love the language, my day jobs have all been "mainstream" OO stuffs like .NET and Java. So I guess my Smalltalk skills are bit rusty now. I've been trying ceaselessly to promote the use of Smalltalk to my boss, colleagues and friends. But so far, it's been futile. It starts to feel a bit lonely here!!! :-) Recently, I felt a bit restless so I started a small personal project in Seaside -- nothing fancy, just a portal for a non-profit. Perhaps, I'll incorporate some of Pier stuffs. Whatever you have in mind, I would love to talk to you, Georg.

Contexts and exception handlers
by David Shaffer 04 Aug '06

04 Aug '06

When saving a context and using it in Compiler>>evaluate:in:to:notifying:ifFail:logged: it doesn't appear that exception handlers are active. Here's a test case which demonstrates my expectations (which are clearly flawed). Can anyone help me understand why this notification isn't caught? BTW, I'm simply trying to figure out how to get the Inspector, Debugger, ObjectExplorer etc to be able to access "dynamic variables" which existed in the context in which the tool was activated.
