Spotify Post-mortem

For a while now I’ve had a Spotify Premium account, and since I told myself it was an experiment which I would then subsequently review, I really ought to actually do that rather than just letting it roll over and over each month.

I assume most of you are familiar with Spotify; if you’re not, then where the hell have you been the last year? It’s pretty much ubiquitous now.

Anyways, Spotify Premium is £9.99 a month, and that entitles you to higher quality music, offline mode, and use on mobile devices, like the iPhone. A full comparison of the different types of account is available on the Spotify website. The main thing that drew me to paying for premium was the use on mobile devices, like my iPhone, and I have used it pretty extensively.

And, based on that experience, I think I’m going to stop paying for it.

There’s a few reasons for this: the catalogue on Spotify isn’t as extensive I would like, and has a really large number of omissions, the software is occasionally unstable, etc. but the major one is mostly a strictly human limitation. I found myself just listening to the same set of music over and over, or I was undecided about what I actually wanted to listen to on any particular day, and Spotify just isn’t geared up to make it easy to browse to find something you want. The tools available for finding entirely new music on Spotify aren’t really very wonderful, either.

What I could do instead with my £10 is just buy a new album (or two) every month, add it to my collection, and then use tools like Genius playlists on the iPhone to listen to the whole damn lot in nicely selected chunks, which I find a really satisfying way of consuming music. This plan also has the advantage that I get to keep all this music if I every subsequently decide to stop paying monthly.

Anyways, I haven’t made any final decisions yet, so I’d be very interested to see what other people think about this, any tips/tricks or perspectives to share would be great.

(Coming up soon: a series of posts about my holiday to Ireland, and hopefully just more posts in general…)

Totally Forgot To Post This

Ages ago, I saw a guy playing a set of drums made from a bike.

He played this:

Yesterday Threw Everything At Me

I had kind of a crazy day yesterday.

It started with an exam in Quantum Field Theory. Painful, but I think it didn’t go too badly. Had a bite to eat, then it was straight into some last minute revision on the Queen’s Lawn for the second exam of the day in Optical Communications Physics, which was actually sort of pleasant, in a slightly strange way. Less like the hideous mental assault which constituted my other exams, anyway.

To celebrate, Rowan, Susan and I took a trip to our customary haunt — Nando’s — and proceded to consume chicken. It was delightful.

After that, I decided to take a trip into central London to grab some comics at Forbidden Planet, and as I was strolling up Monmouth Street I walked past none other than Neil Gaiman, award-winning fantasy writer and graphic novelist. By the time I’d realised it was him he’d already walked past me and gone round the corner. It took me a few more hours to realise that I was in fact carrying in my bag a copy of his “Sandman” graphic novel “Dream Country”, and that asking him to autograph it would have been incredible. I later found out via the wonder of Twitter that he would have signed it if I’d asked. Never mind!

So yeh, went to Forbidden Planet, grabbed a new Buffy comic and a Penny Arcade book, and went and sat down on a wall just up Shaftesbury Avenue and read my purchases for a while, and watched the world go by. I don’t spend nearly enough time in central London, which is a shame because I love it dearly; it’s so full of life and bustle and remarkable buildings and architecture and it goes on and on in all directions.

Rather than go home, I decided to take a bit of a walkabout. I set off east towards Holborn, passing whichever way took my fancy.

The first thing I discovered was what looked to be the entrance to an underground tramway.

A disused and gated tramway under the streets of London

I wonder how long it’s been since it was used, and where the other end of it surfaces, if it still has another end.

I wandered over to where a section of street had been blocked off by Crossrail signs. This old building, a sign on which read “The Ivy House” was abandoned, encircled by signs exhorting me to visit the site office. The building across the street bore the likeness of, and a dedication to, John Bunyan. It too looked decayed and abandoned; I turned the corner into a desolate alley, and leaned to look through some railings; through them smelt of damp and decay.

The building was apparently called “Kingsgate House”, and despite appearing to be derelict, somebody still seems to be in habitation, judging by the light and the open window.

It appears that I’m not the only one to find this building interesting.

Places like this fill me with wonder, make me think about their history, why they were built, and how they fell on hard times. I wonder if Crossrail is doing any good to this little microcosm of Holborn at the moment; I must confess that apart from the Astoria, I’d never really considered the impact the building of Crossrail would have.

I turned north, and found that Warner Brothers keeps replicas of the Hogwarts house insignia in the Foyer of their offices.

From there I wandered into a residential district, near Great Ormond Street hospital. Houses draped with the flag of St. George, people in bars, drinking and chatting, the beautiful chattering sound of people enjoying themselves wafting over the streets. I walked down an alleyway that passed through a building, joining the street through a crack in the facade of a shop. Behind this was tucked a little house, sounds of a party coming from inside.

It was getting late, so I headed in the direction of Russell Square tube station, marvelling at water fountains, and a house draped in lights for some unfathomable reason. I came across a park called Coram’s Fields. The sign above the gate read “No Unaccompanied Adults”. I thought this was marvellous.

Post-Election: A More Expert View

This article from the UK Polling Report is actually a much better guide to what might happen next than I could ever do, seeing as how it contains actual facts.

I think this bit is interesting:

The second issue is the Liberal Democrat party’s rules. Formally Cameron and Brown have a free hand in negotiations, Clegg does not. The Southport Resolution in the Lib Dem rules requires him to get the support of 75% of the Parliamentary Liberal Democrat party, and 75% of the party’s Federal executive (and failing that the support of two-thirds of the wider party) in order to enter into any agreement that “could affect the party’s independence of political action” – taken as meaning a coalition agreement. While all the leaders would in practice need to take their parties with them, only Clegg would have such a formal process to deal with somehow.

For Once, Not Politics or Philosophical Essayism

Whenever I’m not feeling OK, I have a tendency to hit the philosophy. There’s something about contemplating the essential questions of existence that makes your everyday shit seem to be much less of a concern, and more like weird background noise. I’ve finished reading Nausea, my copy of Catcher in the Rye is back on the shelf, and hopefully things will go back to something approximating normal.

I hope I’ve learned something. It was probably something I’d hoped I’d learned before, and no doubt through my own infinite stupidity will need to learn again at some point in the future, but I hope that I’ve learned it for real this time.

Sometimes things end. It’s sad, and sometimes you just can’t understand why, or make sense of what happened, but you can’t howl into the wind and try to change the past with the power of your fury; you’ll just consume yourself in hatred and bitterness and nihilism. Some things just aren’t worth the time, effort or pain trying to fight.

Time to learn to let things end.

In other news, there’s a Fairtrade Cheese & Wine party on Friday night, which I will certainly be going to, and there two events on Thursday I would like to attend but they’re mutually exclusive and I may not have time anyway: Fairtrade tea party, and ICU Election Hustings.

Act accordingly.

Andy out.

Imperial College Union Votes to Rename Bars: #phase3

The Union is currently in the midst of a plan known as Phase 3 to modernise the Union’s bar and nightclub areas in place of the existing dBs and da Vinci’s to make them, y’know, actually decent places to have a night out. I will concede that da Vinci’s is alright, but dB’s is sorely in need of a refurbishment.

Anyways, the Union recently ran a competition to rename these new bars as part of the Phase 3 development, and they’ve just released the final shortlist of names, along with the opportunity to vote which names will be adopted for the new nightclub and bar.

Shortlist for the nightclub:

  • Iris
  • Lab
  • Metric
  • Neighbourhood
  • Theory

Shortlist for the bar:

  • Consort
  • Crown & Shield
  • Library
  • Quad

Now, I will be the first to admit that I did not submit any possible names; mostly this is because I’m ludicrously terrible at naming things. If I ever have children they’re probably going to be named by pasting pages from a baby name book onto a wall, then chucking darts until one strikes a name I like the sound of.

However, somebody at the Union seriously screwed up when they picked this shortlist. Some of the names are just plain terrible and others have the rather more significant problem that the collide with names of places already on campus; the most egregious example here is “Library”, which will have the rather unfortunate effect of making the sentences “Let’s meet at the Library” or “Let’s eat at the Library” ambiguous. I cannot possibly fathom how the brief enjoyment of a moment of irony derived from drinking in a bar called the Library could possibly outweigh the continuing irritation this could well generate for years and years.

“Quad” is broken for the same reason, although to a lesser extent. “Crown & Shield”, presumably drawn from the crown logo of the RCSU and the shield of the CGCU, is basically a massive fuck-you to the miners and the medics, the latter of which needs no further alienation from the rest of IC; it also makes it sound like a pub, which the new bar will not be, the pub niche is filled very well by the Union Bar.

The only half-decent name there is “Consort”, presumably drawn from the Prince Consort Road on which the Union sits, which possesses the fairly unique quality amongst the rest of actually sounding like a bar as well as being vaguely appropriate.

The names for the nightclub are mostly just plain awful. “Lab” is another unfortunate collision. The only decent one there is “Metric”, as you can tell by it being the runaway leader in the polling up to this point.

Speaking of the polling, it is rather severely flawed by the lack of an option to vote RON (re-open nominations) , something which is usually a central part of Union democracy. One wonders if President Ashley Brown‘s experience fighting the battle for election against RON left him with a grudge.

I jest, I jest. He’s been very good in engaging with the dialogue about this on Twitter, and that’s pretty damn admirable.

Anyway, I would suggest scrapping this poll altogether and starting a new one from scratch before this one is allowed to run on too long. Most people I’ve spoken to about these names share my opinion that they’re terrible. All I can say is, I don’t want to see this become a presidential election issue when the presidential candidates publish their election manifestos for next year. I can’t imagine anything quite as ignominious for the current president as to have his successor immediately strike down the voted-for Phase 3 names chosen under his stewardship.

Anyway, as the poll probably isn’t going to be called off, go here and vote for the least bad options. Thank you.

Of the Sun and Streetlights

Did you know that we can measure the magnetic field on the surface of the Sun?

That is something I find absolutely marvellous, that we can measure magnetism on something over 92 million miles away from here, on a surface that’s over 5000 degrees celsius. It’s one hell of a trick, for sure.

It’s accomplished by using a phenomenon called the Zeeman effect, and just a pinch of quantum mechanics. Electrons orbiting the nucleus are only allowed in a set of distinct energy levels, so they can only absorb energy to jump from one level to another. Photons of light have only a certain energy related to their wavelength (or colour); this means that to jump from one given energy level to another, only a very specific colour of light will do.

This means that when certain colours of light hit that atom, they’ll be absorbed and cause electrons to jump into higher energy levels. This causes certain colours of light to be missing when you look at a rainbow (or spectrum) of the light. You can calculate where these lines would be from quantum mechanics. This is how we know what the Sun is made from, for instance.

Now, when you add a magnetic field to the mix, things get a little more interesting. The magnetic field affects the orbit of the electrons, and splits one energy level into many more. This means that there are now more ways for electrons to jump from one level to another, so your neat little spectral absorbtion line will split into many lines: this is the Zeeman effect. You can tell from how much the line has split what the magnetic field strength is.

All these results can be calculated from quantum mechanics, and the Zeeman effect works just as well here on the ground as it does in the Sun. It’s brilliant!

Extra: Spectral lines work in reverse, too. Electrons in higher energy levels in an atom can only lose energy and go into a lower level by emitting a photon of a precise colour. Streetlights, for instance, work by exciting electrons in sodium, which then emit a photon of a very particular orange colour as they drop down into a lower level. This means that streetlights are almost exactly monochromatic (i.e. a single colour).
