Upgrading to kernel 4.9+

I upgraded to kernel 4.9. It apparently fixed the Wi-Fi issues. I still have occasional display glitches, but they also go away while on battery power. Kernel upgrade I upgraded to kernel 4.9+ (i.e. Linus Torvald's master branch as of today). While I ranted two days ago about some changes in how you install software, … Continue reading Upgrading to kernel 4.9+

Goodbye DxO, hello Red Hat

After one year and a half at DxO working on the DxO ONE, a diminutive, yet highly capable camera that fits in your pocket and connects to an iPhone, I've decided to move on and join Red Hat to work on Spice, focusing on 3D acceleration for virtual machines. Free software, virtualization and 3D together, and working … Continue reading Goodbye DxO, hello Red Hat

A real-time, lock-free, multi-CPU flight recorder

Debugging complex, real-time, multi-CPU programs like HPVM, Tao3D or the software in the DxO ONE can be a real challenge. You need detailed information about what's going on, but at the same time, adding instrumentation, e.g. a big bunch of ad-hoc printf statements, can change the behavior of the program sufficiently to make the problem you are chasing … Continue reading A real-time, lock-free, multi-CPU flight recorder

The TL;DR … Continue reading Building all the major open-source web browsers

Animation and 3D: the web is doing it wrong

In Animation and 3D: the web is doing it wrong, I argue that the way the web does animation and 3D is completely bogus and deserves to die. With Tao Presentations, we offer a dynamic document description language that lets us write shorter code that is much closer to storytelling. We'd like to bring this to the … Continue reading Animation and 3D: the web is doing it wrong

When Google oversteps its authority

Recently, a user of Tao Presentations informed us that Google Chrome displayed a dire warning after he downloaded our software: "Tao Presentations may be malicious software". Uh oh, for the average Joe, that's a big no-no. Google locks out "unapproved" programs It's not just us. Recently, I tried to download some of the amazing demos created … Continue reading When Google oversteps its authority
