[BUG] StrikeFont(NewYork12 15) becomes bold after #saveOnFile
by Stephane Rollandin 01 Apr '03

01 Apr '03

hello list; ... the subject says all: my default font is NewYork12 15 when I save a TextMorph or a MenuItemMorph with #saveOnFile, then import the .morph file back in the image, the font becomes NewYork12B 15, bold. OTOH there is no problem with NewYork10 12 (the default one in Squeak 3.4). no problem with StringMorph either. any idea ? Stef

Running Squeak apps off the net
by jennyw 01 Apr '03

01 Apr '03

One of the things that drew me to Squeak initially was that I was under the impression that one could run Squeak applications over the net ... kind of like going to a Web site but getting a full-blown app. instead of a Web page. Was this a misimpression on my part? Or is this something in the works? I got this impression because I read something comparing Squeak to REBOL saying that Squeak had it first ... Thanks! Jen

Re: [Q] Storing a Morph in Magma

But when I tried to retrieve it in another Client I got: "Improper Store into indexable object" ====== Hi Martin, I'm sorry you had that problem. I'm not surprised because I have not yet attempted to store a Morph in Magma, however, it has always been on my list and will be fixed shortly. Magma 1.0gamma4, to be released soon, has several enhancements and a couple of fixes, the most exciting of which are two more substantial performance improvements! I'll see if I can get storage/retrieval of Morphs in there too. Regards, Chris __________________________________________________ Do you Yahoo!? Yahoo!

It's Not A Game
by Beale Screamers Brother 01 Apr '03

01 Apr '03

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 It's Not A Game By "Beale Screamer's Brother" INTRODUCTION ============ This article provides a brief glimpse into two battling Titans--Sony and Microsoft--and how Digital Rights Management (DRM) is playing a crucial role in restricting your freedom and owning a piece of your wallet. Since this is a Squeak mailing list, I thought I would entertain you with a link to Squeak running on an XBox. This article, however, is not about "yet another Squeak port." This article is not about technical tinkering. This article is not even a statement that Squeak is at all suitable as a delivery platform for these next generation consoles, although it would be interesting to be proven wrong. This article is a conflux of ideas and facts, from billion dollar patent infringement litigation, to DRM, to the Digital Millennium Copyright Act (DMCA), and finally to high-performance gaming consoles, that collectively will shape the future of home entertainment, and possibly our children BACKGROUND ========== �Microsoft, like Sony, envisions its next game console as a universal digital box.� -- Dean Takahashi The war to control the home entertainment console is well underway. Sony has a commanding market share. Microsoft entered the battle with XBox, spending billions of dollars to ensure its personal computer dominance translates into a platform for the lucrative home entertainment business. With the addition of broadband connectivity, these consoles finally become a viable channel for Internet-based services to enter your living room. Sony and Microsoft are already designing their next generation consoles. No one can predict the winner, but as Richard Doherty, an analyst at the Envisioneering Group in Seaford, N.Y. stated, "Games are the engine of the next big wave of computing. Kutaragi is the dance master, and Sony is calling the shots." Note: Ken Kutaragi is head of Sony's game division and mastermind of the company's last two game boxes. I assert that these next generation platforms will impact children, teens, adults, and of course businesses, in ways we've never seen before. Some of you may have witnessed your six year old child playing an Electronic Arts sports game (baseball, hockey, basketball). Six year old children simultaneously manipulate the XBox controller's six buttons, three joysticks, and two triggers, while at the same time synthesizing real-time movement of ten basketball players; five under their control. The physical effects of sweat dripping from a child's forehead is a testament to the mental and physical bonding that occurs while using these consoles. Simply stated, it's amazing to watch. These consoles, however, will be used for much more than just gaming, with businesses of all sorts flocking to take advantage of the real-time, real-world, immersive, psychological warping "engine" in your living room. DIGITAL RIGHTS MANAGEMENT ========================= The current generation of home entertainment consoles, Sony�s PlayStation 2 and Microsoft�s XBox, and their next generation consoles, the "Sony PlayStation 3" and "XBox Next," are the springboards that allow both companies to vault into your living room and own a piece of your wallet. These consoles will push the envelope of hardware (including photo-realistic real-time image rendering), software, and price-performance. The number of advanced game console users soared by 128% in 2002, reaching 56.3 million worldwide, according to the latest research from Strategy Analytics� Broadband Entertainment Strategies service. 75% of users own Sony�s PlayStation 2, compared to 13% with Nintendo�s GameCube, and 12% with Microsoft�s XBox. Predictions are that XBox sales will rise by 12% in 2003, fueled by XBox�s growing software library, its clearly defined online gaming strategy, and Microsoft�s substantial investment in the platform. Digital Rights Management (DRM) is a fundamental component of both Sony's and Microsoft's strategy to control not only the distribution of content to these consoles, but to control how and when you use such content. I define "content" as any digital information including but not limited to audio, video and even software. DRM is clearly important to both companies. Sony Entertainment, along with Philips Electronics, recently purchased the DRM pioneering company InterTrust for $453 million dollars. http://www.internetnews.com/bus-news/article.php/1499591 InterTrust has only thirty employees, but owns one of the most extensive DRM patent portfolios in history, comprising 26 issued patents and 85 pending in the U.S. patent office. Stop and think about this: half a billion dollars for thirty people and some patents. As Roger Parloff writes: "InterTrust also has one other asset of note: a suit against Microsoft that appears to be the highest-stakes patent litigation in history.... InterTrust is seeking an injunction barring distribution of about 85% of Microsoft's product line." Sony's acquisition of InterTrust gives them something even more important, as Rober Parloff describes: "Rather, the companies may be acquiring what the feds failed to get via their sputtering antitrust suit: a Microsoft containment strategy." Sony also licensed all of ContentGuard's DRM patents. ContentGuard is a spin-off of Xerox that owns DRM patents created by Xerox PARC's Mark Stefik. http://www.xrml.org/press_120302.asp Together these two licensing deals leave Sony with a formidable DRM patent portfolio, giving Sony one important advantage as it plans the design, implementation, and release of the Sony PlayStation 3. MICROSOFT'S XBOX ================ The Microsoft XBox is a stellar example of using DRM to restrict, and control, the distribution of software, and not just for software licensing reasons, but also for market manipulation reasons. Microsoft considers DRM an important component of XBox's hardware and software design, building in fundamental restrictions to who can and cannot build software that executes on the console. It is clear that Microsoft is taking a two phase approach to controlling home entertainment: 1) build a powerful, useful and successful hardware console and 2) use DRM to control the distribution of software and multimedia content to the console. If Microsoft is successful in gaining living room market share, they can use DRM to maintain and expand their market control, to the detriment of third-party software companies, including Sony. A very technically talented and vocal critic of Microsoft's use of DRM, and the associated DMCA, is "Beale Screamer". Beal Screamer wrote an article entitled "Mad as Hell about the DMCA" and posted it along with source code that breaks the DRM protection of Windows Media audio and video content. http://wwwiuk.informatik.uni-rostock.de/forschung/ ms-digital-rights/Philosophy.html Microsoft is going one step further, negotiating with CPU vendors such as Intel and AMD to include hardware facilities in the CPU, and facilities in the Windows Operating System, that allow much stronger enforcement of DRM policies. Microsoft's code name for this was "Palladium." Microsoft is now calling it the "Next-generation Secure Computing Base." http://www.microsoft.com/presspass/features/ 2002/jul02/0724palladiumwp.asp Ross Anderson, a well respected security professional, has the following thoughts about Palladium. http://ww.cl.cam.ac.uk/~rja14/tcpa-faq.html Squeak on XBox ============== One of the arguably less interesting facts in this article is a brief description of "Squeak on XBox." A technique called "modding" an XBox was used to replace the copyrighted Microsoft BIOS that restricts software from running on the XBox (unless officially "endorsed" by Microsoft) with a new BIOS that removes such restrictions. This enables Squeak to be run on the box without obtaining license and expensive development systems from Microsoft. A description of what is required to get Squeak running on an XBox can be found at the following URI. http://www.geocities.com/beale_screamer_s_brother/squeak_for_xbox.htm The fact that hardware modifications were required to remove "Microsoft handcuffs" in order to get Squeak running is something that should raise your eyebrow. The Future ========== Predicting the future is impossible, inventing the future is challenging, but reacting to the future is perilous. Watch out for the Titans. - --------------------- Original Distribution Date: March 31, 2003 by "Beale Screamer's Brother" -----BEGIN PGP SIGNATURE----- Version: PGP 8.0 iQA/AwUBPoknuQlokGbT4ISWEQI6CgCg/vCwWVQ0/IAuIfWXxyJNuihOnm8AoL9g 4st8xCBZzj8rjo5VEUh0Z+8e =WvBH -----END PGP SIGNATURE----- __________________________________________________ Do you Yahoo!?

so here's a quickie script that looks up the UUIDs: | map names uuids | map _ SMSqueakMap default. map loadUpdates. uuids _ OrderedCollection new. names _ { 'Menus Enhancements'. 'SystemWindow Enhancements'. 'ScrollBars Enhancements'. }. names do: [ :pkgName | uuids add: (map cards keyAtValue: (map cardWithName: pkgName) ifAbsent:[ nil ] )]. uuids then, using the UUIDs, load the packages: | uuids map | map _ SMSqueakMap default. uuids _ { 'd67275c5-1fe7-48ed-be30-60b82154afb9'.

I'll tell you one thing that sounds to me like it might be both useful and relatively easy to improve on - running the simulator. Since it's actually Slang (no dynamic sends), it's already a subset of the full Smalltalk problem (project 1.5?), and since it's currently either compiled externally (clumsy) or interpreted as full Smalltalk (relatively slow), you might make it more easily useful. If the simulator was fast enough to comfortably run regular size images, I guess people would use it more to learn about/debug problem images, and study the VM. Oh, we need to fix it in the image, too, but Craig's doing that... > I don't want to start trying to speed up sends until after > I've got useful byte code speed ups.
