Ofcom blesses Linux-powered, open source DIY radio ‘revolution’
Small scale DAB radio was (quite literally) conceived in an Ofcom engineer’s garden shed in Brighton, on a Raspberry Pi, running a full open source stack, in his spare time. Four years later, Ofcom has given the thumbs up to small scale DAB after concluding that trials in 10 UK cities were judged to be a hit.
We gave you an exclusive glimpse into the trials last year, where you could compare the specialised proprietary encoders with the Raspberry Pi-powered encoders.
“We believe that there is a significant level of demand from smaller radio stations for small scale DAB, and that a wider roll-out of additional small scale services into more geographic areas would be both technically possible and commercially sustainable,” notes Ofcom.
Case in point: I've been using the Apache HTTP server for many years now. Indeed, you could say that I've been using Apache since before it was even called "Apache"—what started as the original NCSA HTTP server, and then the patched server that some enterprising open-source developers distributed, and finally the Apache Foundation-backed open-source colossus that everyone recognizes, and even relies on, today—doing much more than just producing HTTP servers.
Apache's genius was its modularity. You could, with minimal effort, configure Apache to use a custom configuration of modules. If you wanted to have a full-featured server with tons of debugging and diagnostics, you could do that. If you wanted to have high-level languages, such as Perl and Tcl, embedded inside your server for high-speed Web applications, you could do that. If you needed the ability to match, analyze and rewrite every part of an HTTP transaction, you could do that, with mod_rewrite. And of course, there were third-party modules as well.
Linux and Open Source Hardware for IoT
Most of the new 21 open source software projects for IoT that we examined last week listed Linux hacker boards as their prime development platforms. This week, we’ll look at open source and developer-friendly Linux hardware for building Internet of Things devices, from simple microcontroller-based technology to Linux-based boards.
In recent years, it’s become hard to find an embedded board that isn’t marketing with the IoT label. Yet, the overused term is best suited for boards with low prices, small footprints, low power consumption, and support for wireless communications and industrial interfaces. Camera support is useful for some IoT applications, but high-end multimedia is usually counterproductive to attributes like low cost and power consumption.
Fedora 24 -- The Best Distro for DevOps?
If you have been to any DevOps-focused conferences -- whether it’s OpenStack Summit or DockerCon -- you will see a sea of MacBooks. Thanks to its UNIX base, availability of Terminal app and Homebrew, Apple hardware is extremely popular among DevOps professionals.
What about Linux? Can it be used as a platform by developers, operations, and DevOps pros? Absolutely, says Major Hayden, Principal Architect at Rackspace, who used to be a Mac OS user and has switched to Fedora. Hayden used Mac OS for everything: software development and operations. Mac OS has all the bells and whistles that you need on a consumer operating system; it also allows software professionals to get the job done. But developers are not the target audience of Mac OS. They have to make compromises. “It seemed like I had to have one app that would do one little thing and this other app would do another little thing,” said Hayden.
