“Gizmodo has published an article (with video) on the Linux-based free alternative to MS Surface along with a quite interesting interview with its creator, Peter Hutterer. “It may not be as fancy-schmancy as Microsoft Surface or Jeff Han’s demos but this video of a Linux-based MPX multi-touch table shows that things are moving full speed ahead in the land of the free penguins. We talked with developer Peter Hutterer, who gave us his insight on the project, the iPhone and the ongoing multi-touch craze.” He talks about Jeff Han’s work, MS Surface and defines the iPhone as “not the first in what it’s doing, but definitely a huge impact” in the field.”

Linux: Rewriting the x86 Setup Code Luglio 16, 2007

H. Peter Anvin submitted a series of patches rewriting the x86 setup code, “this patch set replaces the x86 setup code, which is currently all in assembly, with a version written in C, using the ‘.code16gcc’ feature of binutils (which has been present since at least 2001.)” He went on to explain why he did this, “the new code is vastly easier to read, and, I hope, debug. It should be noted that I found a fair number of minor bugs while going through this code, and have attempted to correct them.“
Linus Torvalds reacted favorably, “I can’t really argue against this on any sane grounds – not only is it removing more lines than it adds, but moving from mostly unreadable assembly to C seems a good idea.” He went on to note, “so let’s just get this merged. But the question is, do we put it in 2.6.23-rc1, or do we put it in -mm for a few weeks, which would imply waiting for the next merge window? Andrew?” Andrew Morton pointed out that the patches have been in -mm already for a couple of months, “this code has been in -mm since 11 May, as git-newsetup.patch. It has caused (for what it is) astonishingly few problems. Maybe a couple of build glitches and one runtime failure, all quickly fixed. I’d say it’s ready.” Linus agreed, “Ok. That makes it easy. I’ll just merge it.“
