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.

Music has been called by some the greatest thing the human race has ever done, and at its best it is undoubtedly a profound expression of emotion more poetic than anything Shakespeare ever wrote. True, done badly it can sound like a trapped cat in a box of staplers falling down a staircase, but let’s not get hung up on details here- music is awesome.

However, music as we know it has only really existed for around a century or so, and many of the developments in music’s  history that have shaped it into the tour de force that it is in modern culture are in direct parallel to human history. As such, the history of our development as a race and the development of music run closely alongside one another, so I thought I might attempt a set of edited highlights of the former (well, western history at least) by way of an exploration of the latter.

Exactly how and when the various instruments as we know them were invented and developed into what they currently are is largely irrelevant (mostly since I don’t actually know and don’t have the time to research all of them), but historically they fell into one of two classes. The first could be loosely dubbed ‘noble’ instruments- stuff like the piano, clarinet or cello, which were (and are) hugely expensive to make, required a significant level of skill to do so, and were generally played for and by the rich upper classes in vast orchestras, playing centuries-old music written by the very few men with the both the riches, social status and talent to compose them. On the other hand, we have the less historically significant, but just as important, ‘common’ instruments, such as the recorder and the ancestors of the acoustic guitar. These were a lot cheaper to make and thus more available to (although certainly far from widespread among) the poorer echelons of society, and it was on these instruments that tunes were passed down from generation to generation, accompanying traditional folk dances and the like; the kind of people who played such instruments very rarely had the time to spare to really write anything new for them, and certainly stood no chance of making a living out of them. And, for many centuries, that was it- what you played and what you listened to, if you did so at all, depended on who you were born as.

However, during the great socioeconomic upheaval and levelling that accompanied the 19th century industrial revolution, music began to penetrate society in new ways. The growing middle and upper-middle classes quickly adopted the piano as a respectable ‘front room’ instrument for their daughters to learn, and sheet music was rapidly becoming both available and cheap for the masses. As such, music began to become an accessible activity for far larger swathes of the population and concert attendances swelled. This was the Romantic era of music composition, with the likes of Chopin, Mendelssohn and Brahms rising to prominence, and the size of an orchestra grew considerably to its modern size of four thousand violinists, two oboes and a bored drummer (I may be a little out in my numbers here) as they sought to add some new experimentation to their music. This experimentation with classical orchestral forms was continued through the turn of the century by a succession of orchestral composers, but this period also saw music head in a new and violently different direction; jazz.

Jazz was the quintessential product of the United States’ famous motto ‘E Pluribus Unum’ (From Many, One), being as it was the result of a mixing of immigrant US cultures. Jazz originated amongst America’s black community, many of whom were descendants of imported slaves or even former slaves themselves, and was the result of traditional African music blending with that of their forcibly-adopted land. Whilst many black people were heavily discriminated against when it came to finding work, they found they could forge a living in the entertainment industry, in seedier venues like bars and brothels. First finding its feet in the irregular, flowing rhythms of ragtime music, the music of the deep south moved onto the more discordant patterns of blues in the early 20th century before finally incorporating a swinging, syncopated rhythm and an innovative sentiment of improvisation to invent jazz proper.

Jazz quickly spread like wildfire across the underground performing circuit, but it wouldn’t force its way into popular culture until the introduction of prohibition in the USA. From 1920 all the way up until the Presidency of Franklin D Roosevelt (whose dropping of the bill is a story in and of itself) the US government banned the consumption of alcohol, which (as was to be expected, in all honesty) simply forced the practice underground. Dozens of illegal speakeasies (venues of drinking, entertainment and prostitution usually run by the mob) sprung up in every district of every major American city, and they were frequented by everyone from the poorest street sweeper to the police officers who were supposed to be closing them down. And in these venues, jazz flourished. Suddenly, everyone knew about jazz- it was a fresh, new sound to everyone’s ears, something that stuck in the head and, because of its ‘common’, underground connotations, quickly became the music of the people. Jazz musicians such as Louis Armstrong (a true pioneer of the genre) became the first celebrity musicians, and the way the music’s feel resonated with the happy, prosperous feeling surrounding the economic good times of the 1920s lead that decade to be dubbed ‘the Jazz Age’.

Countless things allowed jazz and other, successive generations to spread around the world- the invention of the gramophone further enhanced the public access to music, as did the new cultural phenomenon of the cinema and even the Second World War, which allowed for truly international spread. By the end of the war, jazz, soul, blues, R&B and all other derivatives had spread from their mainly deep south origins across the globe, blazing a trail for all other forms of popular music to follow in its wake. And, come the 50s, they did so in truly spectacular style… but I think that’ll have to wait until next time.
