Basically, my thesis was that many institutes of higher learning are no longer teaching CS majors what computers are all about from a low-level perspective (CPUs, caches, data busses and the like) and this is causing a http://EmbeddedGurus.net/pointers/2008/05/lack-of-embedded-system-jobs.htmlnoreply@blogger.com (PTR-Mike)tag:blogger.com,1999:blog-34943068.post-7666780028254689235Mon, 04 Feb 2008 15:21:00 +00002008-02-04T10:39:14.165-05:00Greetings! I've noticed something over the past few months. Namely, none of the commercial distributions of embedded Linux support Debian-based distributions for development. Neither WindRiver, MontaVista, LynuxWorks, nor Timesys support any Debian-based installations. This rules out easily installing any of their commercial products on distributions like Ubuntu. Yes, I know that you can http://EmbeddedGurus.net/pointers/2008/02/lack-of-embedded-support-for-debian.htmlnoreply@blogger.com (PTR-Mike)tag:blogger.com,1999:blog-34943068.post-3257056109587587007Tue, 04 Dec 2007 00:42:00 +00002007-12-03T22:22:55.461-05:00We hear a lot of noise from the silicon manufacturers today about how multi-core processors are the wave of the future. Certainly, they do allow us to pack more performance into a single package. However, are they a good fit for embedded systems? One argument is that with two or more cores at a lower voltage, we can run with a lower thermal dissipated power envelope. This is certainly http://EmbeddedGurus.net/pointers/2007/12/multi-core-solution-or-problem.htmlnoreply@blogger.com (PTR-Mike)tag:blogger.com,1999:blog-34943068.post-2049118887672208946Thu, 06 Sep 2007 13:12:00 +00002007-09-06T09:27:40.450-04:00Well... From my last post I reported that Palm had announced the development environment for for the Palm Foleo was stripped version of Wind River's WorkBench product. I also stated that I thought that shipping the Foleo with a 2.4 kernel was a mistake given that 2.6 has been around for over 3 years now. In addition, I commented that the WorkBench environment cost as much as the Foleo itself, http://EmbeddedGurus.net/pointers/2007/09/palm-foleo-is-dead.htmlnoreply@blogger.com (PTR-Mike)tag:blogger.com,1999:blog-34943068.post-3242071828588000275Wed, 05 Sep 2007 13:29:00 +00002007-09-05T12:02:43.154-04:00Greetings! It's been about 6 weeks since my last posting. Sorry for the delay, but I've been at LinuxWorld and spent the past couple of weeks in Alaska with my family. Alaska was awesome. But, since I didn't strike it rich panning for gold, I'll have to keep working my day job :-). The topic of this posting is LinuxWorld. This is the traditional gathering of all things Linux in San http://EmbeddedGurus.net/pointers/2007/09/linuxworld-and-mobile-devices.htmlnoreply@blogger.com (PTR-Mike)tag:blogger.com,1999:blog-34943068.post-7709288996100541451Thu, 05 Jul 2007 15:10:00 +00002007-07-05T12:26:23.874-04:00Well, GPLv3 has finally been released. This is an attempt by many of the movers and shakers in the open-source community to close the loop holes found in GPLv2. However, as someone who is trying to use Linux in many different types of embedded applications, I find GPLv3 somewhat troubling. The reality of the embedded space is that silicon vendors such as Marvell, make it almost impossible to http://EmbeddedGurus.net/pointers/2007/07/will-gplv3-make-linux-irrelevant.htmlnoreply@blogger.com (PTR-Mike)tag:blogger.com,1999:blog-34943068.post-623021522184640846Mon, 18 Jun 2007 21:31:00 +00002007-06-18T18:11:02.400-04:00Spacecraft applications have long been the bastion of proprietary solutions. Custom RAD-hard processors, custom bus architectures and custom command and control software are the typical fare of space-borne platforms. The use of all of this custom hardware and software makes access to space an incredibly expensive venture. All of this is before you can find a lift vehicle to get you to orbit! http://EmbeddedGurus.net/pointers/2007/06/carrier-grade-linux-in-space.htmlnoreply@blogger.com (PTR-Mike)tag:blogger.com,1999:blog-34943068.post-116249002693180501Thu, 02 Nov 2006 17:18:00 +00002006-11-02T12:53:47.033-05:00OK, I know that this topic has been addressed before, but times are a changin'. With the latest set of real-time patches being accepted into the 2.6.18 kernel, Linux is really becoming capable of hard, real-time performance. With the introduction of priority inheritance support and interrupt threads, we can now see a level of determinism that was previously only available in the RTOSes and http://EmbeddedGurus.net/pointers/2006/11/hard-real-time-linux-vs-rtoses.htmlnoreply@blogger.com (PTR-Mike)tag:blogger.com,1999:blog-34943068.post-115910038246703152Sun, 24 Sep 2006 12:09:00 +00002006-09-24T08:19:42.473-04:00How can it be that universities are graduating students in Computer Science that don't know some form of assembly language? I can't begin to count the number of students in my Embedded Linux device driver courses that have never seen a data sheet and don't know what a register is. They want to know how to write a board support package (BSP), but they don't speak assembly language and never http://EmbeddedGurus.net/pointers/2006/09/compsci-schools-hurting-embedded.htmlnoreply@blogger.com (PTR-Mike)
