I am consolidating a lot of files. I have archives of Internet drafts, from over the years. I just pulled down all the current Internet Drafts. I want to mv all my other stored IDs to this current directory ONLY if, they are larger. You may be aware that when a draft is expired, a small file is left in the directory for some time with content like: "This Internet-Draft has been

Hi Could anybody explain me how to check how many L1/L2 cache my cpu have. I'm using CentOS 5.6 *cat /proc/cpuinfo |grep CPU * model name : Intel(R) Core(TM)2 Duo CPU T9300 @ 2.50GHz model name : Intel(R) Core(TM)2 Duo CPU T9300 @ 2.50GHz Diagram of a generic dual-core processor, with CPU-local level 1 caches, and a shared, on-die level 2 cache.

With 1.6.1, I'm trying to set up a test of meetme for creating dynamic conferences. cat meetme.conf [rooms] conf => 600 extensions.conf: [meetme] exten => 2663,1,MeetMe(,D) exten => 2663,n,Hangup() exten => 2666,1,MeetMe() exten => 2666,n,Hangup() What I'm expecting is to dial 2663, get a conference room number ( 600, I suppose since it's the only room ), and set

Ok so the install has been seamless on a few machines and I decided to try it on my laptop (a Dell D620). I had everything working great and kicked it around a bit and then figured, if I'm going to keep this on my laptop I'll need to reformat everything, enable some encrypted filesystems etc ... not a big deal ... kind of Here's the problem, the laptop has a resolution of 1440x900 and

Hello, In the recent days we have been debugging a really thorny issue where binaries build with clang and linked with lld was just "Killed" when started on a specific armv7 device we ship on. After quite a bit of head scratching it turns out that the kernel on this device ships with a 32k default page size (getconf PAGESIZE) and lld uses 4k default page size. We fixed this by passing

On linux (not Windows) I doubt using Ninja vs make will make drastic differences.. (Others with actual numbers please chime in to correct me) /* I think the difference could be more beneficial if you're doing incremental builds, but I don't think that is what you're doing.. */ On Thu, Feb 25, 2016 at 1:51 PM, Sedat Dilek via llvm-dev <llvm-dev at lists.llvm.org> wrote: > On

I have an odd problem and I was wondering if anyone has ever run into this before.

Today, /etc/system was updated to increase the maximum number of groups from 16 to 32. After the system was rebooted, things seemed to be working as expected, however one of our
