OLPC XO C-Sound demo

This article did a good job demonstrating the versatility of OLPC XO. My preference is the C-Sound demo. I imagine the impact this hardware will cause on developing countries especially the young musicians. An orchestra that uses OLPC XO as a musical instrument is not too far from the future. Perhaps I should test it as well.

Getting ready for Vanlug

Busy weekend. I just took a break for making a presentation of Fedora Core 6 and Fedora Project for Vancouver Linux Users Group which will debut on November 20, 2006.

While the line is selected, convert into path from the menu Path -> Stroke to Path or press Ctrl+Alt+C on the keyboard. For the rectangle, Path -> Object to Path or Ctrl+Shift+C .

On the menu Extension -> Modify Paths -> Jitter Nodes . Leave the default settings and apply effects.

HP, Linux and ACPI

Majority of HP hardware running on Linux and even Microsoft reported an issue related to a non-standard compliant ACPI. Notable message below repeats at least three times on the boot: 4.876549] ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D128] at bit offset/length 128/1024 exceeds size of target Buffer (160 bits) (20190215/dsopcode-198) [ 4.876555] ACPI Error: Aborting method \HWMC due to previous error (AE_AML_BUFFER_LIMIT) (20190215/psparse-529) [ 4.876562] ACPI Error: Aborting method \_SB.WMID.WMAA due to previous error (AE_AML_BUFFER_LIMIT) (20190215/psparse-529) The bug is a known for years from which Linux kernel team are unable to fix without the help of vendor i.e. HP. Here is a compilation of reports: BIOS error: The BIOS in this system is not fully ACPI compliant. ACPI BIOS ERROR (blue screen) on startup ACPI bad works with Linux The good news is some errors seems harmless. Unfortunately, such errors displayed the quirks approach used by
