Magnussoft, the company now responsible for development on Zeta, has announced it is accepting pre-orders for Zeta 1.21. This new release will include multi-user support, will be built with GCC4, among other improvements. Bernd Korz's weblog contains more information. Korz was (is?) the CEO of YellowTAB, the company that started Zeta. Read on for a short editorial on this announcement.

Fair enough. It was my understanding that BeOS/Zeta/Haiku used ELF and GCC as a system compiler. Following a symbolic link at compile time is a job for ld, and I'm going to ass-u-me that BeOS/Zeta/Haiku also use GNU binutils, yes?
Can the BeOS/Zeta/Haiku RTLD seriously not tell the difference between the filenames "libfoo.so.1" and "libfoo.so.2" in the DT_NEEDED section? Does it ignore the second part of the filename?
Even if it can't do that, it doesn't really change my point though, just the mechanism. Instead of libfoo.so.1 and libfoo.so.2 you could have libfoo.so and libfoo_2.so if you so wished; they are distinct libraries. Provided you do not try to mix GCC 2.95 and GCC 4 libraries together it should work.
This is exactly how we handle ABI changes in libsyllable. Whenever the ABI changes we increment the DSO version and ship the previous versions for compatability. So an installed system may have libsyllable.so.5, libsyllable.so.6 and libsyllable.so.7 installed. The only time this couldn't be done sensibly was when we upgraded to Glibc 2.3, which involved much deeper voodoo and it was easier to drop the old libraries.

"This is my NeXTstation Turbo Color booting the Mac System 7.1 Operating System using a hardware add-on called 'Daydream'. The Daydream has a Mac ROM and a few custom ICs in it and hooked up to the NeXTs DSP port. Turns your NeXT into a full fledged 68k powered Mac." So cool.

"The NetBSD Project is pleased to announce NetBSD 6.1, the first feature update of the NetBSD 6 release branch. It represents a selected subset of fixes deemed important for security or stability reasons, as well as new features and enhancements. Please note that all fixes in the prior security/bugfix updates (NetBSD 6.0.1 and 6.0.2) are also in 6.1."

"At the end of a week in which Electronic Arts confirmed it wasn't developing a thing for the Wii U, one of the software engineers in EA Sports' Canada studio, in a series of since-deleted tweets, disparaged the console as 'crap' and suggested Nintendo should give up on hardware altogether. 'The Wii U is crap. Less powerful than an Xbox 360. Poor online/store. Weird tablet', tweeted Bob Summerwill, listed as a senior software engineer at EA Canada, in a reply to a tweet posting a link about EA's no-Wii U news. 'Nintendo are walking dead at this point'." The Wii U is turning into the 21st century's Virtual Boy.

"In NixOS, the entire operating system - the kernel, applications, system packages, configuration files, and so on - is built by the Nix package manager from a description in a purely functional build language. The fact that it's purely functional essentially means that building a new configuration cannot overwrite previous configurations. Most of the other features follow from this." Interesting approach. A Linux distribution, sure, but with some very refreshing ideas about system configuration.

Appfour added, among other features, C/C++ support to its new version of AIDE. From Android-IDE, "Now you can write parts of your app or your whole app in C/C++ on your device. AIDE supports the Standard Android NDK toolchain (GCC 4.6 + Bionic, STL, ...). No changes are necessary if you want to build an app developed on a PC with Eclipse. C/C++ development is fully integrated: Build errors appear in the error list and files can easily be navigated to with Go to file. The editor supports C/C++ syntax highlighting."

Ars nails it: "The answer is that Google did announce what amounts to a fairly substantial Android update yesterday. They simply did it without adding to the update fragmentation problems that continue to plague the platform. By focusing on these changes and not the apparently-waiting-in-the-wings update to the core software, Google is showing us one of the ways in which it's trying to fix the update problem."

"It is good for programmers to understand what goes on inside a processor. The CPU is at the heart of our career. What goes on inside the CPU? How long does it take for one instruction to run? What does it mean when a new CPU has a 12-stage pipeline, or 18-stage pipeline, or even a 'deep' 31-stage pipeline? Programs generally treat the CPU as a black box. Instructions go into the box in order, instructions come out of the box in order, and some processing magic happens inside. As a programmer, it is useful to learn what happens inside the box. This is especially true if you will be working on tasks like program optimization. If you don't know what is going on inside the CPU, how can you optimize for it? This article is about what goes on inside the x86 processor's deep pipeline."

"It was the only moment I heard regret slip into Otellini's voice during the several hours of conversations I had with him. 'The lesson I took away from that was, while we like to speak with data around here, so many times in my career I've ended up making decisions with my gut, and I should have followed my gut,' he said. 'My gut told me to say yes.'" The world would've been a much different place - Apple would have been less dependant on Samsung for its chips, which probably would've meant less money for Samsung to develop its Galaxy business.

Glass is getting some love at Google I/O as well. New applications have been released - Facebook, Twitter, Evernote, Elle, Tumblr, and CNN. Perhaps more interesting: the newly announced Google Glass Developer Kit will allow offline applications and direct hardware access - great for hacking and expanding Glass' potential. This kit will really allow hackers to put Glass through its paces.

"But Beck and Merrill decided that simply banning toxic players wasn't an acceptable solution for their game. Riot Games began experimenting with more constructive modes of player management through a formal player behavior initiative that actually conducts controlled experiments on its player base to see what helps reduce bad behavior. The results of that initiative have been shared at a lecture at the Massachusetts Institute of Technology and on panels at the Penny Arcade Expo East and the Game Developers Conference." Absolutely fascinating stuff. I'm a League of Legends player, and to be honest, the community isn't nearly as bad as some make it out to be. I'm happy Riot games has the guts to employ science to address the issue.More News »

Vanders, BeOS doesn't use versioned Shared Objects for System libs. This then kills your entire point. BeOS != LINUX.
JT is right on this one. Listen to him.
To include the entire API again would needlessly expand the entire install base. If you are breaking binary compatibility, it should be all or nothing IMO. (Isn't that what Syllable dod to the original libAtheos.so?) You then have issues like linking drivers to the Kernel, input filters to the input server, various bits and pieces to the App server. That's just the tip of the iceberg.
I've looked at writing a thunking layer for BeOS to allow GCC 3.x to be used in plain R5.03. Way, way too much work.
