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.

Finding its feet

My last post on the recent history of western music took us up until the Jazz Age, which although it peaked in the 1920s, continued to occupy a position as the defining music genre of its age right up until the early 1950s. Today’s post takes up this tale for another decade and a half, beginning in 1951.

By this time, a few artists (Goree Carter and Jimmy Preston, for example) had experimented with mixing the various ‘black’ music genres (country and western, R&B and a little gospel being the main ones) to create a new, free rocking sound. However, by the 50s radio, which had been another major force for the spread of jazz, had risen to prominence enough to become a true feature of US life, so when Cleveland DJ Alan Freed first started playing R&B intentionally to a multiracial audience even his small listenership were able to make the event a significant one. Not only that, but the adolescents of the 50s were the first generation to have the free time and disposable income to control their own lives, making them a key consumer market and allowing them to latch onto and fund whatever was new and ‘cool’ to them. They were the first teenagers. These humble beginnings, spreading ‘black’ musical experiments to the masses, would later become the genre that Freed himself would coin a name for- rock and roll.

Rock and roll might have originally been named by Freed, and might have found its first star in Bill Haley (the guy wrote ‘Rock Around The Clock’ in 1955), but it became the riotous, unstoppable musical express train that it was thanks to a young man from Memphis, Tennessee, who walked into Sun Records in 1953 to record a song for personal use. His name was Elvis Presley.

’53 might have been Presley’s first recording experience, but his was not a smooth road. In eighth grade music he is reported to have only got a C and be told that he couldn’t sing, a claim that was repeated when he failed an audition for a local vocal quartet in January 1954. However, in June of that year he recorded a 1946 blues hit ‘That’s All Right’, totally altering what had been a lovelorn lament of a song into a riotous celebration. He, Winfield Moore and Bill Black (the guitarist and bassist he was recording with) had created a new, exciting, free-flowing sound based around Presley’s unique singing style. Three days later, the song aired on local radio for the first time and calls flooded in demanding to know who the new singer was. Many were even more surprised when they found out that it was a straight laced white boy playing what was previously thought of as ‘black music’.

Completely unintentionally, Elvis had rewritten the rulebook about modern music- now you didn’t have to be black, you didn’t have to play the seedy venues, you didn’t have to play slow, old, or boring music, you didn’t have to be ‘good’ by classical standards, and, most important, your real skill was your showmanship. Whilst his two co-performers in the early days were both natural showmen, Presley was a nervous performer to start with and his legs would shake during instrumental sections- the sight of a handsome young man wiggling his legs in wide-cut trousers proving somewhat hysterical for female sections of the audience, and worked the crowd into a frenzy that no previous performer had managed.

Elvis’ later career speaks for itself, but he lost his focus on writing music in around 1960 as, along with the death of Buddy Holly, the golden years of rock ‘n’ roll ended. However, the 50s had thrown up another new innovation into the mix- the electric guitar. Presley and his competitors had used them in their later performances, since they were lighter and easier to manoeuvre on stage and produced a better, louder sound for recorded tracks, but they wouldn’t come to their own until ‘the golden age of rock’ hit in the mid 60s.

By then, rock n roll had softened and mellowed, descending into lighter tunes that were the ancestors of modern pop music (something I’m not sure we should be too thankful to Elvis for), and British acts had begun to be the trailblazers. British acts tended towards a harder sound, and Cliff Richard enjoyed a period of tremendous success in the USA, but even then the passage of rock had eased off slightly. It wasn’t new any more, and people were basically content to carry on listening- there wasn’t much consumer demand for a new sound. But then, the baby boomers hit. The post-war goodwill in the late 40s and early 1950s had resulted in a spike in the birth rate of the developed world, and by around 1963 that generation had began to grow up. A second wave of teenagers hit the world, all desperate to escape the dreary boredom of their parents’ existence and form their own culture, with their own clothing, film interests, and, most importantly, music. The stage was set for something new to revolutionise the world of music, and the product that did was made in Britain.

Numerous bands from all over the country made up the British rock scene of the early 1960s, but the most prolific area was Liverpool. There rock and roll once again underwent a fusion with subgenres such as doo wop, and (again) R&B, formulating itself into another new sound, this time centred around a driving, rhythmic beat based upon the electric guitar and drum kit. These beats formed a key part of the catchy, bouncy, memorable melodies that would become the staple of ‘beat’ music. This had taken over the British music scene by 1963, but by 1964 a British song had made number 1 in the US charts. It was called ‘I Want To Hold Your Hand’, and was written by four Liverpudlians who called themselves The Beatles.

To this day, the Beatles are the most successful musicians ever (sorry fellow Queen fans- it’s true). Their first appearance on the Ed Sullivan show in 1964 set a new record for an American TV audience (over 70 million)- a show they only did because Sullivan’s plane had been forced to circle Heathrow Airport in the middle of the night so that this band he’d never heard of could land first and wade their way through their screaming fans. Sullivan decided then and there he wanted to interview them. Along with other British acts such as The Rolling Stones and The Kinks, beat took the US by storm- but they were only the first. The Beatles’ first and greatest legacy was the structure of a rock band; all band members wrote their own songs based on the drums & electric guitar. All that was left was for acts like the Stones to cement singer/lead guitarist/bassist/drummer as the classic combination and the formula was written. The music world was about to explode; again

And this story looks like taking quite a few more posts to tell…
