Nested X servers hate me

Goal: run Compiz in a nested X server. Or really, any X server that is not the one I’m using for real work. List O’ Failures: “Screw it, just run the regular X server on another virtual console.” DRI can only be used on one console at a time. Lose. “Xephyr supports GLX in latest […]

Xnest, Xephyr, Xgl, Xdmx…

Does anyone know a way to hack on a GL-based compositing manager such as Compiz in a nested X server? I didn’t even try Xnest assuming there’s no way it works; Xephyr has GLX and Composite but Compiz reports that the root window has the wrong visual; Xgl appears to be dead (?) and isn’t […]

Changes

After almost 9 years, today was my last day at Red Hat. I’ll miss it, and all the great people there. It’s not time yet to say what I’m working on now, and may not be time for a while. In the meantime, I’ll be around in all the usual places you might expect to […]

Linux for Consumers

For years now I’ve complained about the term “desktop” — an evil word that blinds us to more interesting opportunities to use free software in consumer-facing products. Look at all the recent examples. Built on GNOME technology, we’ve had Maemo from Nokia and OpenMoko for a while, and One Laptop Per Child. More recently, we […]

Online Desktop Tour

I wrote a short Red Hat Magazine article, complete with screenshots, touring online desktop in Fedora 8. (This post was originally found at http://log.ometer.com/2007–11.html#13)

GNOME Fonts Broken By Default

Apparently someone has decided to be pedantic and set my font DPI to 50 by default. Without changing some number of other things, this is a regression, and broken. To avoid the many problems this creates the decision was made long ago to simply make the DPI always 96. This is also what Windows does, […]

Preferences on the Network

For a long time people have talked about an LDAP or other network-located backend for GConf. Unfortunately writing GConf backends is painful and in some ways not really possible, for example the backend interface does not support change notifications originating from the backend. Presumably Ryan’s dconf will address some of this. In the meantime, we […]

John Markoff Goes Online

I don’t think John Markoff at the New York Times knows about the GNOME Online Desktop effort, but Owen noticed this blog post where Markoff works around a hard drive crash with a Linux LiveCD and web-based apps, just as we’ve proposed. He calls it Computing in the Cloud. What I discovered was that — […]

Money Math

While I’m on financial topics, if you don’t know how to do “time value of money” math you should stop and learn about it right now. For all I know I’m the only person who didn’t learn this in high school, but in case there’s someone else, here’s a blog post. Because of inflation and […]

Investment Perspective

This week’s Fortune magazine has a scary black cover and says “Market Shock 2007.” The market drop was 10%! Not very large in historical terms, and it comes after a huge gain. But from the news (in Fortune and almost everywhere else) it sounds like we should be freaking out. I thought I’d post the […]
