The existing fix involves using prevent_tail_call() to prevent the gcc tail call optimization, though Linus notes, “the problem isn’t even really fundamentally tailcalls, that just is the detail that happens to trigger the problem (but I could imagine other situations triggering it _too_“. Tail calls are when the last line of one function returns a call to another function, something commonly optimized by compilers.

Linus acknowledged that the current hack in the kernel code is ugly, suggesting that the proper fix is for the gcc team to add an attribute allowing code to tell gcc it doesn’t own the argument stack, “I’d much rather have ‘asmlinkage’ tell gcc directly that it doesn’t own the stack, but no such attribute exists, so we’re stuck with our hacky manual ‘prevent_tail_call()’ macro once more (we’ve had the same issue before with sys_waitpid() and sys_wait4()).” He then went on to propose a cleaner hack to solve the same problem in a more generic way, not specific to the tail call optimization.

Debian的开发人员经过讨论和投票，终于决定有条件的采用GNU Free Documentation License （GFDL）作为他们文档的协议。Debian曾经对GFDL是否真正的自由表示担忧，这篇决议文章说明了Debian为什么一直将GFDL的文档作为“不自由”（non-free）的部分发布。这篇文章从包括DRM等三个角度说明了GFDL对自由的局限性。

什么样的自由才是open source需要的？是在一定限制下的自由，还是完全的自由？(完全自由是什么概念？)， GNU在3方面对License作了约束，但是Debian会出台一个完全自由的并且没有个约束的License吗？如果第一天真有一个这么个Licence发布，第二天就修改为 My dog is cute~

第一篇：说了下linux在desktop哪点做得不好
第二篇：说了下关于linux下license的问题，并且还结合oracle收购innodb对mysql造成的影响这个实例进行了双licenses的弊端

The Linux Standard Base (LSB) is an application binary interface (ABI) for Linux and Linux-compatible platforms. The LSB draws on the source standards of the IEEE POSIX standards and The Open Group’s Single UNIX Specification for many of its behavioral interface definitions. Some interfaces are not included in the LSB, since they are outside the remit of a binary runtime environment; typically these are development interfaces or user-level tools. The LSB also extends the source standards in other areas (such as graphics) and includes the necessary details such as the binary execution file formats to support a high volume binary application platform.
If you are an end user looking for Linux distributions that support open standards, please see our list of LSB certified products.
If you are a developer looking to build portable Linux applications that will work on these distributions, please see our Download and Documentation pages.

这里有一篇关于LSB3.1影响的文章

]]> http://linuxren.org/lsb31%e5%af%b9linux%e7%95%8c%e7%9a%84%e5%bd%b1%e5%93%8d/feed/ http://linuxren.org/lsb31%e5%af%b9linux%e7%95%8c%e7%9a%84%e5%bd%b1%e5%93%8d/ LSB 3.1放出 http://feedproxy.google.com/~r/Linuxren/~3/-npfqeAT86s/ http://linuxren.org/lsb-31%e6%94%be%e5%87%ba/#comments Wed, 26 Apr 2006 09:26:00 +0000 LinuxRen http://linuxren.org/articles/lsb-31%e6%94%be%e5%87%ba.html 第一个规定linux桌面系统的标准终于放出，看起来内容很多，不知道有没有壮士给翻译一下？

LSB 3.1标准可以使得程序员在任何一个遵循该标准的linux系统上所开发的程序可以运行在其他任何同时遵循该标准的linux系统上，目前，遵循该标准的企业有：IBM, HP, Novell, Red Hat, Sun Microsystems and Real Networks.

Upgrades：大概看了一下，一共9章

第一章：主要说了下LSB3.1的作用，还有一些其他繁文缛节的东西。
第二章：主要规定了ELF的文件格式。
第三章：对基本库进行了规定，也就是所谓的系统调用接口
第四章：一些工具类库的规定。
第五章：对命令跟一些工具软件的规定。
第六章：对程序执行环境进行了规定。
第七章：对系统初始化的时候应该做的事情进行了规定。
第八章：对用户和组进行了规定。
第九章：对包的格式和安装进行了规定。

仅仅是大概的看了看，考虑全部翻译成中文，当然要等到正是版本发布的时候。(this supposed to be a beta version)

It seems as though the Macintosh and Linux client ports for America’s Army (the popular free FPS game based upon the Unreal engine and is supported by the US Army) is a drowning matter. Icculus has revealed details that the US Army has stopped paying him to port the America’s Army game clients from Microsoft Windows to Linux and Macintosh OS X operating systems. However, there is still some hope left for the Linux ArmyOps server port. America’s Army v2.7.0 is expected in the very near future, and to this point there is still no client ArmyOps v2.6 port for either alternative operating system. Icculus has stated he is willing to work pro-bono on these client ports, however, time is the limiting factor in this world. For Linux gaming advocates (such as Phoronix) this is another blow to the gaming belt. To reiterate, here is an excerpt from Icculus’ message — “To be clear, there aren’t plans to abandon the Linux server at this point, but at this time, the non-Windows clients are basically gone.” We at Phoronix cordially thank Ryan Gordon for the exception work he had done with the America’s Army client, and we wish him the best of luck on all of his Linux/Mac ports for the near future and the ones he is presently working on. His message can be found at his finger. It has been almost a year since we last interviewed Icculus, but we hope to strike up another interview period soon. If you happen to have any nail-scratching questions you would like answered by Ryan, feel free to contact us.
