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.

NSA recommends several Samsung smartphones

The list of allowed smartphones, which US officials may share confidential information has become a bit longer. The National Information Assurance Partnership (NIAP) - a product tester under the supervision of the NSA - announced Tuesday the green light for the S5 Galaxy, Galaxy Note 4 and the tablet Galaxy Note 10.1 (2014 Edition).

Ubuntu 14.10 Linux 32-bit vs. 64-bit Performance

Given yesterday's story about Ubuntu 16.04 LTS potentially being the last 32-bit release if that proposal goes through, and given the number of people still running 32-bit Linux distributions on Intel/AMD hardware that is 64-bit capable, here's some fresh x86 vs. x86_64 benchmarks using Ubuntu 14.10. Using Ubuntu 14.10 with the latest daily development ISOs today -- just ahead of this week's official Utopic Unicorn debut -- I did clean installs of both x86 and x86_64 flavors and carried out the same benchmarks with the same settings. Using the open-source Phoronix Test Suite automated benchmark framework made all testing easy and effortless. Read more

U.S. government releases open source gamification software

The United States' National Geospatial-Intelligence Agency has made some of its internally-developed gamification software available for free on GitHub under the MIT free software license. Developers may find it useful as a tool for configuring a server to track "gamification" systems like points or badges against user accounts on apps or websites; at the very least, it offers interesting insight into how the NGA is using game design tenets in its training programs.

Let's Pay for Open Source with a Closed-Source Software Levy

This column has often explored ways in which some of the key ideas underlying free software and open source are being applied in other fields. But that equivalence can flow in both directions: developments in fields outside the digital world may well have useful lessons for computing. A case in point is a fascinating post by James Love, Director of Knowledge Ecology International (KEI), a non-governmental organisation concerned with public health and other important issues. It is called "The value of an open source dividend", and is a discussion of the problems the world of pharma faces because of the distorting effect of patents - problems it shares with the world of computing...
