Cleaning Up the Web

“As a normal user, the single most important thing you can do is to complain to sites which do not support Standards and lock their customers into using a single browser.

No one wants to read rude or insulting feedback. When you contact the site, be polite, professional and courteous. Explain to them the problem you experienced, how to reproduce it and tell them the browser you are using.”

Clarity on APIC and ACPI

“APIC and ACPI are two different things: the former is an Advanced Programable Interrupt Controller, it’s required for multiprocessor systems so interrupts can be delivered to either CPU; the latter is the Advanced Configuration and Power Interface, it’s the successor to both APM and PNP providing power management and Plug-and-Play functionality for modern systems.”

Roxen’s Distinguishing Characteristics

Here is some interesting Roxen information that might be worth noting: the Licensing and Features of their CMS, and their own GPL’ed webserver software that it runs on.

Dynaflow’s Keyfile

Dynaflow does not like spaces in the path when specifying the location of a license key file in Windows. You can either create an easier path for its license file or utilize the DOS equivalent path and place that into your PATH environment variable.

Bigred Linux Mirror

Bigred now re-directs to a static webpage describing the Linux mirror available there. I’ll be adding custom channels for departmental software rollout, but anyone is free to use it immediately for network installs or updates.

I hope to add Debian or Ubuntu soon, but its more work that I’d rather not do alone. I already coordinate with two other departments, so if you’re interested on collaborating feel free to contact me.

For more, see http://bigred.princeton.edu/.

CSS Positioning Confusion

Although I don’t do any web design, occasionally I like to spruce up one of my support-related sites (like this one). CSS positioning is something I care to remember, but in the past I have found this guide most useful.

Poor NVIDIA Graphics on s2885 and Linux

For about 3 weeks (give or take a week) a machine has been out of action due to this bug fixed as part of the kernel-smp-2.4.21-20.EL.i686.rpm package. The problem was kernel support for the Tyan s2885 motherboard’s AGP architecture. It manifested itself in terms of graphic hardware acceleration. Even though the proper graphics card drivers were installed (in this case NVIDIA), no acceleration was evident, glxinfo | grep “direct render” returned a value of “no”, glxgears reported 2000FPS (later we would get 8000) and Matlab benchmarks were pathetic.

Sticking with RHEL (distros with the 2.6 kernel couldn’t see 2 processors on the board) and upgrading the kernel did the trick for the X environment for the most part. The NVIDIA driver needed to be installed according to the manufacturer’s directions and passed the line Option “NvAGP” “3″ in the X config. Finally, even though glxgears demonstrated a marked improvement in 3D rendering speed, Matlab refused to speed up in the 3D category. It was only when I pointed the symbolic links libGL.so and libGLU.so in Matlab’s sys/opengl/lib/glnx86/ to their /usr/X11R6/lib64 counterparts that performance improved.
