  • For ASCII-art fans, the chains are arranged like so: (Note: this is a very different arrangement from the 2.0 and 2.2 kernels!) _____ Incoming / \ Outgoing -->[Routing ]--->|FORWARD|-------> [Decision] \_____/ ^ | | v ____ ___ / \ / \ |OUTPUT| |INPUT| \____/ \___/ ^ | | ----> Local Process ---- The three circles represent the three chains mentioned above. When a packet reaches a circle in the diagram, that chain is examined to decide the fate of the packet. If the chain says to DROP the packet, it is killed there, but if the chain says to ACCEPT the packet, it continues traversing the diagram.

  • Profiling entire system activity with sysprof
  • Profiling an application lets you see what functions are taking up most of the CPU time so you can concentrate your optimization efforts on making the those pieces of code run faster. With sysprof, you can profile all the applications that are running on your machine
  • To get the most out of sysprof you should also install the debug information for all the applications you wish to profile. Without the debug information you will see only the name of a shared library in the profile information and not be able to tell what functions are taking up the lion's share of time spent in that library.

  • So what is the main benefit of choosing Slackware Linux over other distributions? First and foremost, it's the clean and uncomplicated system, with no hidden surprises, that is perhaps Slackware's biggest asset. As commented recently by a poster on a popular web site, it is the only major distribution that has resisted the temptation to add custom features and other bloat to Linux. Slackware is as pure and natural as a Linux distribution can be - it comes with a vanilla kernel and it includes just the necessary libraries, as well as a well-balanced set of development tools, desktop and server packages. Nothing more and nothing less.

  • This long-standing odd/even development model was officially scrapped in 2004 thanks to the success that Linus and Andrew Morton were having working together, and significant "unstable" development began happening between each 2.6.Z release.

  • Awesome tip! I can use this. MacFuse makes your entire system very unstable. It gives many kernel panics. Eek! YMMV.

  • "We made the change, quite honestly, because we are absolutely making a set of steps that make it more difficult for competitors that wish to provide support services on top of Red Hat Enterprise Linux," Red Hat chief technology officer Brian Stevens tells The Register, before naming those competitors. "Today, there are two competitors that I'm aware of that go to our customers directly, offering to support RHEL directly for them...Oracle and Novell."
  • "The work that we've done should not impede companies from building their own versions of Linux and supporting those for their customers," he says. "All the code we deliver through RHEL is out there. In most cases, the changes that go into RHEL. We already distribute into the upstream kernel. We have an upstream-first policy, where we're developing openly and then later integrating into our tree and then delivering it. So it shouldn't at all impede the community or anybody that's in the business of competing on that."

RMS On Header Files and Derivative Works - Slashdot - 2 views

slashdot RMS FLOSS copyright law header linux

shared by Marc Lijour on 20 Mar 11 - No Cached
  • "In this email from 2003, Richard Stallman says 'I've talked with our lawyer about one specific issue that you raised: that of using simple material from header files. Someone recently made the claim that including a header file always makes a derivative work. That's not the FSF's view. Our view is that just using structure definitions, typedefs, enumeration constants, macros with simple bodies, etc., is NOT enough to make a derivative work. It would take a substantial amount of code (coming from inline functions or macros with substantial bodies) to do that.' This should help end the recent FUD about the Android 'clean headers.'"

Castle storage file system linux

shared by Yi Wang on 28 Jul 11 - No Cached
  • The standard Linux storage stack wasn’t designed for write-heavy big data workloads, nor is it well-suited to modern hardware: large, slow SATA disks, SSDs or many cores. Castle, an open-source project, is a ground-up overhauling of RAID, file systems, and the POSIX interface. It is released under the GPL and runs as part of the Linux kernel. Our target is 1 million random inserts per second to disk on a $1,000 commodity box, and we’re nearly there. Castle is also the core of the Acunu Data Platform, which delivers up to 100x higher performance for applications written for Cassandra and other tools.
