The Epitome of Nerd-dom

A short while ago, I did a series of posts on computing based on the fact that I had done a lot of related research when studying the installation of Linux. I feel that I should now come clean and point out that between the time of that first post being written and now, I have tried and failed to install Ubuntu on an old laptop six times already, which has served to teach me even more about exactly how it works, and how it differs from is more mainstream competitors. So, since I don’t have any better ideas, I thought I might dedicate this post to Linux itself.

Linux is named after both its founder, Linus Torvalds, a Finnish programmer who finished compiling the Linux kernel in 1992, and Unix, the operating system that could be considered the grandfather of all modern OSs and which Torvalds based his design upon (note- whilst Torvald’s first name has a soft, extended first syllable, the first syllable of the word Linux should be a hard, short, sharp ‘ih’ sound). The system has its roots in the work of Richard Stallman, a lifelong pioneer and champion of the free-to-use, open source movement, who started the GNU project in 1983. His ultimate goal was to produce a free, Unix-like operating system, and in keeping with this he wrote a software license allowing anyone to use and distribute software associated with it so long as they stayed in keeping with the license’s terms (ie nobody can use the free software for personal profit). The software compiled as part of the GNU project was numerous (including a still widely-used compiler) and did eventually come to fruition as an operating system, but it never caught on and the project was, in regards to its achieving of its final aims, a failure (although the GNU General Public License remains the most-used software license of all time).

Torvalds began work on Linux as a hobby whilst a student in April 1991, using another Unix clone MINIX to write his code in and basing it on MINIX’s structure. Initially, he hadn’t been intending to write a complete operating system at all, but rather a type of display interface called a terminal emulator- a system that tries to emulate a graphical terminal, like a monitor, through a more text-based medium (I don’t really get it either- it’s hard to find information a newbie like me can make good sense of). Strictly speaking a terminal emulator is a program, existing independent of an operating system and acting almost like one in its own right, directly within the computer’s architecture. As such, the two are somewhat related and it wasn’t long before Torvalds ‘realised’ he had written a kernel for an operating system and, since the GNU operating system had fallen through and there was no widespread, free-to-use kernel out there, he pushed forward with his project. In August of that same year he published a now-famous post on a kind of early internet forum called Usenet, saying that he was developing an operating system that was “starting to get ready”, and asking for feedback concerning where MINIX was good and where it was lacking, “as my OS resembles it somewhat”. He also, interestingly,  said that his OS “probably never will support anything other than AT-harddisks”. How wrong that statement has proved to be.

When he finally published Linux, he originally did so under his own license- however, he borrowed heavily from GNU software in order to make it run properly (so to have a proper interface and such), and released later versions under the GNU GPL. Torvalds and his associates continue to maintain and update the Linux kernel (Version 3.0 being released last year) and, despite some teething troubles with those who have considered it old-fashioned, those who thought MINIX code was stolen (rather than merely borrowed from), and Microsoft (who have since turned tail and are now one of the largest contributors to the Linux kernel), the system is now regarded as the pinnacle of Stallman’s open-source dream.

One of the keys to its success lies in its constant evolution, and the interactivity of this process. Whilst Linus Torvalds and co. are the main developers, they write very little code themselves- instead, other programmers and members of the Linux community offer up suggestions, patches and additions to either the Linux distributors (more on them later) or as source code to the kernel itself. All the main team have to do is pick and choose the features they want to see included, and continually prune what they get to maximise the efficiency and minimise the vulnerability to viruses of the system- the latter being one of the key features that marks Linux (and OS X) over Windows. Other key advantages Linux holds includes its size and the efficiency with which it allocates CPU usage; whilst Windows may command a quite high percentage of your CPU capacity just to keep itself running, not counting any programs running on it, Linux is designed to use your CPU as efficiently as possible, in an effort to keep it running faster. The kernel’s open source roots mean it is easy to modify if you have the technical know-how, and the community of followers surrounding it mean that any problem you have with a standard distribution is usually only a few button clicks away. Disadvantages include a certain lack of user-friendliness to the uninitiated or not computer-literate user since a lot of programs require an instruction typed into the command bar, far fewer  programs, especially commercial, professional ones, than Windows, an inability to process media as well as OS X (which is the main reason Apple computers appear to exist), and a tendency to go wrong more frequently than commercial operating systems. Nonetheless, many ‘computer people’ consider this a small price to pay and flock to the kernel in their thousands.

However, the Linux kernel alone is not enough to make an operating system- hence the existence of distributions. Different distributions (or ‘distros’ as they’re known) consist of the Linux kernel bundled together with all the other features that make up an OS: software, documentation, window system, window manager, and desktop interface, to name but some. A few of these components, such as the graphical user interface (or GUI, which covers the job of several of the above components), or the package manager (that covers program installation, removal and editing), tend to be fairly ubiquitous (GNOME or KDE are common GUIs, and Synaptic the most typical package manager), but different people like their operating system to run in slightly different ways. Therefore, variations on these other components are bundled together with the kernel to form a distro, a complete package that will run as an operating system in exactly the same fashion as you would encounter with Windows or OS X. Such distros include Ubuntu (the most popular among beginners), Debian (Ubuntu’s older brother), Red Hat, Mandriva and Crunchbang- some of these, such as Ubuntu, are commercially backed enterprises (although how they make their money is a little beyond me), whilst others are entirely community-run, maintained solely thanks to the dedication, obsession and boundless free time of users across the globe.

If you’re not into all this computer-y geekdom, then there is a lot to dislike about Linux, and many an average computer user would rather use something that will get them sneered at by a minority of elitist nerds but that they know and can rely upon. But, for all of our inner geeks, the spirit, community, inventiveness and joyous freedom of the Linux system can be a wonderful breath of fresh air. Thank you, Mr. Torvalds- you have made a lot of people very happy.

The Consolidation of a World Power

I left my last post on the history of music at around 1969, which for many independent commentators marks the end of the era of the birth of rock music. The 60s had been a decade of a hundred stories running alongside one another in the music world, each with their own part to play in the vast tapestry of innovation. Jimi Hendrix had risen from an obscure career playing the blues circuit in New York to being an international star, and one moreover who revolutionised what the music world thought about what a guitar could and should do- even before he became an icon of the psychedelic hippie music world, his hard & heavy guitar leads, in stark contrast to the tones of early Beatles’ and 60s pop music had founded rock music’s harder edge. He in turn had borrowed from earlier pioneers, Jeff Beck, Eric Clapton, The Who (perhaps the first true rock band, given their wild onstage antics and heavy guitar & drumkit-based sound) and Bob Dylan (the godfather of folk rock and the blues-style guitar playing that rock turned into its harder sound), each of whom had their own special stories. However, there was a reason I focused on the story of the hippie movement in my last post- the story of a counter-culture precipitating a musical revolution was only in its first revolution, and would be repeated several times by the end of the century.

To some music nerds however, Henrix’s death aged just 27 (and after just four years of fame) in 1970 thanks to an accidental drug overdose marked the beginning of the end. The god of the guitar was dead, the beautiful voice of Janis Joplin was dead, Syd Barrett had broken up from Pink Floyd, another founding band of the psychedelic rock movement, and was being driven utterly insane by LSD (although he thankfully later managed to pull himself out of the self-destructive cycle and lived until 2006), and Floyd’s American counterparts The Velvet Underground broke up just four years later. Hell, even The Beatles went in 1970.

But that didn’t mean it was the end- far from it. Rock music might have lost some of its guiding lights, but it still carried on regardless- Pink Floyd, The Who, Led Zeppelin and The Rolling Stones, the four biggest British bands of the time, continued to play an active role in the worldwide music scene, Zeppelin and The Who creating a huge fan rivalry. David Bowie was also continuing to show the world the mental ideas hiding beneath his endlessly crisp accent, and the rock world continued to swing along.

However, it was also during this time that a key division began to make itself firmly felt. As rock developed its harder sound during the 1960s, other bands and artists had followed The Beatles’ early direction by playing softer, more lyrical and acoustic sounds, music that was designed to be easy on the ear and played to and for mass appeal. This quickly got itself labelled ‘pop music’ (short for popular), and just as quickly this became something of a term of abuse from serious rock aficionados. Since its conception, pop has always been more the commercial enterprise, motivated less by a sense of artistic expression and experimentation and more by the promise of fame and fortune, which many consider a rather shallow ambition. But, no matter what the age, pop music has always been there, and more often than not has been topping the charts- people often talk about some age in the long distant past as being the ‘best time for music’ before returning to lambast the kind of generic, commercial consumer-generated pop that no self-respecting musician could bring himself to genuinely enjoy and claiming that ‘most music today is rubbish’. They fail to remember, of course, just how much of the same kind of stuff was around in their chosen ‘golden age’, that the world in general has chosen to forget.

Nonetheless, this frustration with generic pop has frequently been a driving force for the generation of new forms of rock, in an attempt to ‘break the mould’. In the early seventies, for example, the rock world was described as tame or sterile, relatively acoustic acts beginning to claim rock status. The Rolling Stones and company weren’t new any more, there was a sense of lacking in innovation, and a sense of musical frustration began to build. This frustration was further fuelled by the ending of the 25-year old post war economic boom, and the result, musically speaking, was punk rock. In the UK, it was The Sex Pistols and The Clash, in the USA The Ramones and similar, most of whom were ‘garage bands’ with little skill (Johnny Rotten, lead singer of The Sex Pistols, has frequently admitted that he couldn’t sing in the slightest, and there was a running joke at the time on the theme of ‘Here’s three chords. Now go start a band’) but the requisite emotion, aggression and fresh thinking to make them a musical revolution. Also developed a few years earlier was heavy metal, perhaps the only rock genre to have never had a clearly defined ‘era’ despite having been there, hiding around the back and on the sidelines somewhere, for the past 40 or so years. Its development was partly fuelled by the same kind of musical frustration that sparked punk, but was also the result of a bizarre industrial accident. Working at a Birmingham metal factory in 1965 when aged 17, Black Sabbath guitarist (although they were then known as The Polka Tulk Blues Band) Tony Iommi lost the the ends of his middle and ring fingers on his right hand. This was a devastating blow for a young guitarist, but Iommi compensated by easing the tension on his strings and developing two thimbles to cover his finger ends. By 1969, his string slackening had lead him to detune his guitar down a minor third from E to C#, and to include slapping the strings with his fingers as part of his performance. This detuning, matched by the band’s bassist Geezer Butler, was combined with the idea formulated whilst watching the queues for horror movie Black Sabbath that ‘if people are prepared to make money to be scared, then why don’t we write scary music?’, to create the incredibly heavy, aggressive, driving and slightly ‘out of tune’ (to conventional ears) sound of heavy metal, which was further popularised by the likes of Judas Priest, Deep Purple and Motley Crue (sorry, I can’t do the umlauts here).

Over the next few years, punk would slowly fall out of fashion, evolving into harder variations such as hardcore (which never penetrated the public consciousness but would make itself felt some years later- read on to find out how) and leaving other bands to develop it into post-punk; a pattern repeated with other genres down the decades. The 1980s was the first decade to see hip hop come to the fore,  partly in response to the newly-arrived MTV signalling the onward march of electronic, manufactured pop. Hip hop was specifically targeted at a more underground, urban circuit to these clean, commercial sounds, music based almost entirely around a beat rather than melody and allowing the songs to be messed around with, looped, scratched and repeated all for the sake of effect and atmosphere building. From hip hop was spawned rap, party, funk, disco, a new definition of the word DJ and, eventually, even dubstep. The decade also saw rock music really start to ‘get large’ with bands such as Queen and U2 filling football stadiums, paving the way for the sheer scale of modern rock acts and music festivals, and culminating, in 1985, with the huge global event that was Live Aid- not only was this a huge musical landmark, but it fundamentally changed what it meant to be a musical celebrity, and greatly influenced western attitudes to the third world.

By the late 80s and early 90s the business of counter-culture was at it again, this time with anger directed at a range of subjects from MTV tones, the boring, amelodic repetition of rap and the controversial policies of the Reagan administration that created a vast American ‘disaffected youth’ culture. This music partly formulated itself into the thoughtful lyrics and iconic sounds of bands such as REM, but in other areas found its expression and anger in the remnants of punk. Kurt Cobain in particular drew heavy inspiration from ‘hardcore’ bands (see, I said they’d show up again) such as Black Cloud, and the huge popularity of Nirvana’s ‘Smells Like Teen Spirit’ thrust grunge, along with many of the other genres blanketed under the title ‘alternative rock’ into the public consciousness (one of my earlier posts dealt with this, in some ways tragic, rise and fall in more detail). Once the grunge craze died down, it was once again left for other bands to formulate a new sound and scene out of the remnants of the genre, Foo Fighters being the most prominent post-grunge band around today. In the UK things went in a little different direction- this time resentment was more reserved to the staged nature of Top of the Pops and the like, The Smiths leading the way into what would soon become indie rock or Britpop. This wave of British bands, such as Oasis, Blur and Suede, pushed back the influx of grunge and developed a prominence for the genre that made the term ‘indie’ seem a bit ironic.

Nowadays, there are so many different great bands, genres and styles pushing at the forefront of the musical world that it is difficult to describe what is the defining genre of our current era. Music is a bigger business than it has ever been before, both in terms of commercial pop sound and the hard rock acts that dominate festivals such as Download and Reading, with every band there is and has ever been forming a part, be it a thread or a whole figure, of the vast musical tapestry that the last century has birthed. It is almost amusing to think that, whilst there is so much that people could and do complain about in our modern world, it’s very hard to take it out on a music world that is so vast and able to cater for every taste. It’s almost hard to see where the next counter-culture will come from, or how their musical preferences will drive the world forward once again. Ah well, we’ll just have to wait and see…
