Do you know how can do it? Compiler vendors are expected to write their own scripts, which is not a trivial task. The "B Tests" have deliberate errors, marked with "-- ERROR:"

Soapbox
Hi all, I thought y''all might be interested in seeing a newly released website named Soapbox which was written in Rails. Soapbox features reviews of products, businesses, services, and anything else you can think of written by the people *you* care about. http://soapboxit.com Thanks!

Mere chat on vectorisation matters
Hi, people. Allow me to chat a tiny bit on two vectorisation-related matters, in the context of R. I'm curious about if the following ideas have ever been considered, and rejected already. First is about using the so-called Duff's device for partially unrolling loops. I did not overly check in R sources, and am not familiar with them anyway, but the only usage I saw is within

Draggables and Droppable performance (tips)
Hi all. I have some performance tips to share. I had been having problems with the overall performance of the drag/drop objects. This is due largely to the fact that my project really pushes the limits (potentially thousands of draggables and hundreds of droppables in the document at a time, although that is the extreme case). Something I discovered is that the performance of dragging goes WAY

Understanding the ARC - arc_buf_hdr and arc_buf_t
I?m trying to understand the inner workings of the adaptive replacement cache (arc). I see there are arc_bufs and arc_buf_hdrs. Each arc_buf_hdr points to an arc_buf_t. The arc_buf_t is really one entry in a list of arc_buf_t entries. The multiple entries are accessed through the arc_buf_t?s b_next member. Why does the arc_buf_hdr point to a list of arc_buf_ts and not just one arc_buf_t, i.e.,

Mounting Floppies
Hi - daft one for Friday morning coffee break: I have been trying to mount floppies on a couple of CentOS5 servers - the usual "mount /dev/fd0 /mnt/floppy" (yes, /mnt/floppy exists!). On both servers, the mount command just doesn't come back and I have to hit CTRL-C. I have tried different media and also changed the floppy drive on one server, /dev/fd0 is seen as present on both

SIGSEGV on CentOS6
We're been running the distribution version of Samba 3.6.9 as DC on Centos 6 for a few weeks now with a number of Samba 4 clients. We have ~20,000 machine and user accounts in our password database. We see a SIGSEGV every 24-48 hours or so in tcopy_passwd. I built a Samba 3.6.24 with debugging symbols and waited for a core file which we got this morning. Looking through the code we can

Possible ZFS Bug - Causes OpenSolaris Crash
I?d like to report the ZFS related crash/bug described below. How do I go about reporting the crash and what additional information is needed? I?m using my own very simple test app that creates numerous directories and files of randomly generated data. I have run the test app on two machines, both 64 bit. OpenSolaris crashes a few minutes after starting my test app. The crash has occurred on

ZFS Internals Deep Dive - Where can I find it?
The September 16, 2006 entry in Jeff Bonwick?s blog says ?Bill Moore and I will host a four-hour deep dive into ZFS internals at the 2006 Storage Developer Conference in San Jose.? Were the contents of this deep dive ever published in a document or video? If not, will there be another ZFS internals deep dive in the future? I have found Jeff Blanchard?s ZFS deep dive at

tftp problems with VIA EPIA-M board
I'm trying to boot linux on a VIA EPIA-M board (a Nehemiah-based M10000), and I'm having some trouble with it. I'm watching the network transactions with ethereal, and I'm seeing a failure at what appears to be the tftp stage. The M10000 picks up its IP address from the dhcp server (ISC DHCP3), and reports it correctly on the screen. Then the tftp session starts, and I get the

[LLVMdev] Indirect Branch Representation
Actually, I am trying to implement a frontend for conversion from binary to LLVM. In binary, we would encounter branch indirect instructions like, Br Reg, where Reg would be an equivalent virtual register in LLVM. So, we can't directly implement Switch block method here to represent this instruction as we don't know how the values of Reg are mapped to basic blocks. I was going through

Recommended testing approaches for new Mongrel handlers?
Okay, I got off my duff this week and have been finishing Mongrel support for IOWA. I now have two handlers that I need to test. One is similar to the Rails handler, passing request handling to IOWA threads in the same process, and the other allows one or more Mongrel processes to pass requests to one or more separate IOWA processes, with session affinity. Is there any set of standard sorts of

Sysinux 6 will not boot ISOs on BIOS (i.e. pre-UEFI) systems
It occured with every BIOS system I tested on (none of them Dell): 1. HP G62 laptop (i3) 2. Samsung RV520 (i3) Don't know what system Philip Muller uses; have copied him in as he has far more technical knowledge than I do. Syslinux tested from Arch and Manjaro (an Arch derivative). Basically found then when creating latest ISO images. I may be missing something as well about the FMs. Just
