So I'm sitting in the tracing discussion at this year's Linux Foundation Collaboration Summit. One presenter discussed a tracing facility called utrace. This got me thinking of all the different _trace utilities I could name off the top of my head: dtrace, ptrace, strace, and utrace. Then I wondered how many letters of the English alphabet already serve as prefixes to the word 'trace' as software utilities. My cursory research indicates 21/26.

Oh yeah, I looked them all up:

    * atrace: I can't find any software utility named atrace
    * btrace: Tracing for Java
    * ctrace: multi-threaded trace/debug library
    * dtrace: Sun's comprehensive framework
    * etrace: There are things out there called etrace, but they don't seem to be software tracing utilities
    * ftrace: Fast traceroute for Win32; also ftrace: function tracer
    * gtrace: Graphical front-end to traceroute
    * htrace: apparently an extension to windbg
    * itrace: not Apple-related (see ktrace); this stands for instruction strace
    * jtrace: Java rewrite of a speech recognition technique called TRACE
    * ktrace: Kernel tracing for certain BSDs including Mac OS X
    * ltrace: Linux utility to monitor library calls
    * mtrace: Memory debugger in the GNU C library
    * ntrace: Tracing for .NET applications
    * otrace: Oracle database tracing
    * ptrace: Process tracing in Linux
    * qtrace: Another traceroute utility
    * rtrace: Ruby-Trace almost qualifies
    * strace: Tracing system calls
    * ttrace: Tracing facility for multithreaded processes
    * utrace: Linux tracing
    * vtrace: System-wide profiling of WinNT or Win2K
    * wtrace: Provides information to debug methods (pertains to Tivoli?)
    * xtrace: Tracing for X servers
    * ytrace: Nothing
    * ztrace: Lots of things called ztrace, but none seem to be software

So, if you must make a new tracing utility, atrace, etrace, rtrace, ytrace, and ztrace all seem to be open.

Thanks for sitting through another of my pointless surveys. Oh, and thanks also to Google for providing Summit attendees with free, unlocked Nexus One phones. I haven't seen many other mentions of this. Maybe Google does this so often that it barely counts as news anymore.

Thanks to some work done by Eric Whitney, when he accidentally ran the
command "mkfs.ext4 -t xfs", and created a ext4 file system without a
journal, it appears that main scalability bottleneck for ext4 is in the
jbd2 layer. In fact, his testing on a 48-core system shows that on some
workloads, ext4 is roughly comparable with XFS!

привет, лор. я правда девочка и у меня правда гента. обоину сама рисовала, иконки в доке и лаунчер меню перекрашивала тоже сама. иконки папок - гномовские, опять же перекрашеные в розовый. шрифты убунты, тема рабочего стола - G-Remix

- Ппц, 9 страниц комментариев. Я так подозреваю, даже если сам Линус свой рабочий стол выложит - и то меньше будет.
- Линус, выкладывающий свой рабочий стол - это не разрыв шаблона. Вот если Линус выложит на стол - вот это будет разрыв шаблона.
