Ode to Machine Architecture

Filed under
Hardware
Software

I have been writing lately about the importance of learning the underlying tenants of computing if you are going to be a great programmer, and in particular some machine language and computer architecture.

It typically does not make a difference which architecture you learn, or which machine language, as long as the architecture and machine language can illustrate the basic concepts of computing to a level that is useful in future studies of operating systems design and compiler theory, helping you to under stand issues like cache management, interrupt handling and I/O.

This blog entry, however, is not going to talk about those issues. Instead it will talk about a few instances in my life where knowing assembly language helped me immensely in solving problems.

Architecture Does Matter

People seemed to like my blog yesterday about how the knowledge of assembly and machine language improved my programs, or the programs of people around me.

Today I would like to show people how simply understanding a little about the architecture of the machine and operating system, even without knowing assembly language, can improve program performance. Likewise the study of algorithms and computer techniques.

Notifications Without User Interaction on Ubuntu Are Annoying

The Unity desktop environment has a simple and rather ineffective system notification mechanism and it looks like that's not going to change, not even with the arrival of Unity 8. Read more

Librem Linux Laptop Drops NVIDIA Graphics But Still Coming Up Short Of Goal

One of the oddest things I found about the crowd-funded Librem 15 laptop when writing about it last month was that it wanted to be open-source down to the component firmware/microcode yet they opted to ship with a NVIDIA GPU. In an updated earlier this month, at least they came to their senses and dropped the discrete NVIDIA GPU. While I have no problems recommending NVIDIA graphics for Linux gamers and those wanting the best performance, that's only when using the proprietary drivers, and certainly wouldn't recommend it for a fully open-source system -- NVIDIA on the desktop side doesn't do much for the open-source drivers, let alone down to the firmware/microcode level. Instead the Librem folks have opted to upgrade the design to using an Intel Core i7 4770HQ processor that features more powerful Intel Iris Pro 5200 Graphics, which isn't as powerful as a discrete NVIDIA GPU but at least is more open-source friendly.

2014 Catalyst Linux Graphics Benchmarks Year-In-Review

With the year quickly coming to an end, it's time to do our year-end driver recap benchmarks from the year for the proprietary AMD and NVIDIA graphics drivers as well as the open-source drivers. To get things started, here's benchmarks done of the official AMD Catalyst Linux releases of 2014 and testing these drivers on three different graphics cards. Read more
