I’ve a couple of cartoons I like a lot in the current Phoenix. This is my favourite of the ones they didn’t use. You always feel like you’ve done a better quality cartoon if you don’t need any words.
I assume you’ve all come to terms with this story by now. Yes processed meat definitely definitely causes cancer, but… that’s OK for some reason. You can frame it in more or less scary ways. A few years ago I heard one researcher put it this way: “There is no safe dosage for smoked or chemically preserved meat.” In other words, even the smallest amount increases your risk of cancer.
Which is terrifying. It’s only when you look at the actual figures that you get some perspective. I don’t remember them precisely, but the gist was that processed meats take the very small chance you have of contracting bowel cancer, and increase that by a small percentage. So yes, cutting processed meats out of your diet will decrease your risk of getting bowel cancer, but it reduces it from very small to very slightly not as small.
Or put it in another way: Among the reasons for and against meats, be they ethical, environmental, or nutritional, this makes bugger all difference.
The cartoon I admit doesn’t convey all the subtlety of that.
In other cartoon news – there’s something big coming up. I don’t want to talk about it much yet because, well, I guess I’m superstitious. Also, because I can’t really get my head around it yet. More details when I calm down!
That wasn’t even going to be my big news. Last night I drew the first comic strip I did for far too long. It’s for the Phoenix Christmas annual, and damn I like it. I was already fully excited by that, so now I don’t know where I am.
Well I suppose I’m a programmer now. Of all things.
It’s not what I expected, to be honest. I still associate the word with men in lab coats and bow ties in front of banks of flickering lights, doing arcane things at rattly teleprinter terminals. Something to do with rockets probably. Robots even. And punched paper tape!
Punched paper tape was amazing, I used to collect discarded lengths of it from offices where my mother worked as a temp. Its perforated patterns are the perfect metaphor for the state of computing when I was a child. Pretty, delicate, clearly meaningful and yet profoundly mysterious.
These days? It’s writing really. You’re using language, a kind of language, to convey your intended meaning. Like much writing it’s part creativity, part drudgery and repetition. Long-separated senses of the word “hack” meet by surprise in a foreign city.
And like their natural counterparts, programming languages are a pretty diverse bunch. But you’ll hardly find two more different than the ones I just certified in – SQL and PHP. They’re like Choctaw and Chinese. Or more helpfully, Latin and English. One is (relatively) ancient, dusty and rule-bound, the other young and a bit anarchic.
Strangely though, it’s the old one that was actually designed to be English-like. And in the time of the lab coats I guess it seemed like it. A SQL command is called a “statement”, and is constructed much like a sentence:
Select roses, tulips from basket join bouquet where colour = "red"
Sounds almost like the real thing, doesn’t it? But…
Select camel, serendipity from D547 join moonslip where fandango = "buttocks"
…is equally meaningful. The resemblance to human language is superficial for a reason: In SQL there is only a handful of verbs, representing the very limited set of things you can do with items in a database. Its ‘nouns’ are little more than arbitrary labels. Real language is almost immeasurably more complex than that.
The thing that makes SQL seem completely unnatural though is its obsession with data types. These are important up to a point of course. You need to know what kind of data you’re dealing with, whether it’s numbers, “string” (which is what programmers like to call written words), dates and times, or more exotic stuff. You can’t add a word to a number or multiply a date.
But in SQL these break down into seemingly endless subtypes: For a number you need to know what the base is, whether it has a decimal point, if it’s positive or negative. With words it matters what the language is so that the right characters are used, plus you need to know what alphabetical order is for those characters, whether case is significant and so on. Dates and times are available in a mind-bending range of formats, depending on, say, whether you’re more interested in events since 1,000 AD or 1970.
Where it gets ludicrous is that there are still further subdivisions, into units of different size. (My favourite is called the Binary Large Object – or for short, BLOB.) The idea was to set aside only as much space as your data is going to need. If you have a column wide enough for six-figure sums and then enter numbers in the hundreds, you’re effectively saving blank decimal places to your hard disk. In the ’70s, disks were expensive. There was no room for empty space.
Compared to this, PHP seems like it was invented by hippoes. (I meant to say hippies there but I’m going to leave the typo in.) It’s just so… relaxed, skipping lightly over the very things that make SQL tedious. It seems to just guess what your data type ought to be. “You’re trying to add a number and a letter together? No problem, let’s see what happens.”
What makes it even more like human language though is the fact that it’s “Object Oriented”. This is a big idea so I’ll leave the details for another post, but suffice it to say that like real nouns, an object in OO programming is meant to represent something in the world. As such it comes with its associated “verbs” (known as methods) that represent the actions characteristic of that object. So the things that exist in your program have hidden powers that you can call upon if you know the right words. Cool.
Perhaps the best comparison then is not with different natural languages, but with different specialised jargon. Moving from SQL to PHP feels a lot like leaving contract law to take up alchemy.
As of 5.15 pm today, I am an Oracle-certified MySQL developer!
Somewhere in the distance, a dog barks.
Yeah, OK. Boasts that you have to explain are not good boasts. For the last four months I have been studying hard for a qualification in something most people have never even heard of.
Which is a shame, because it is actually the secret language that runs the world.
But first, let me tell you about my day. This was… a tough day. Not only did I take a two and a half hour professional exam, I attended a two hour public meeting right after. The way it began though – well that was even worse.
You know when you know you’re doing something wrong? I mean, when the front of your mind thinks everything’s all right but the back of your brain is waving frantically to get your attention? The feeling you’re forgetting something that you decide to ignore. The nagging awareness that you probably shouldn’t blog while drinking a bottle of wine. Sometimes you know deep down that you’re making a mistake but it just doesn’t seem to reach the surface. So yesterday evening I was being very organised for my exam. I did all the little things, like making sure the car had petrol and water – even that the windscreen washers were working properly. Yet even as I did it I thought to myself: “You know, there’s a danger here. This is breaking my routine. If I break my routine to do all these checks, I could forget one of the important things I do routinely. Fortunately though, I haven’t forgotten anything this time.”
So I finished checking the windscreen washers and went peacefully to bed. Leaving the the car electrics switched on.
This morning an hour went on trying to charge, shove, and sometimes swear the battery back into life before I eventually got a jump start off a neighbour; hardly the calm and collected pre-exam preparation they recommend. Perhaps it was for the best though. Had I time I would probably have indulged in some last-minute panicky “study” as likely to confuse as to clarify. And the record shows I actually seem to do better in exams when faced with non-starting cars. It wasn’t déjà vu, this did happen before.
Outside the venue I met up with Nick and Diarmuid, two of the best students in the class, and was relieved to find that they seemed at least as nervous as me. Because we were (for no readily apparent reason) doing the exam in batches of three, we had feedback from those who sat it earlier in the day. The news was… mixed. On one hand, almost everyone so far had passed. On the other, they had all said it was harder than they’d expected. You can imagine which of those hands seemed more significant to three people about to walk into an exam.
Or about to try. We went to the front door only to find a sign saying to use the side door. We went to the side door only to find it locked. We rang the intercom, only to get an answering machine. I hope I didn’t actually leave the message that went through my head at that point.
But they let us in eventually, and when they’d done with mugshots and fingerprinting (well, almost) they sat us at the consoles. The exam is a computer-based, multiple choice affair not dissimilar to the driving theory test. Except instead of being about stuff everyone needs to know, it’s about stuff nobody in their right mind wants to even think about. I had a tense moment when the very first question was completely unintelligible to me, another when I came to one that, I will swear to my dying day, did not have any possible correct answer. But mostly I felt like I was doing OK. Afterwards Mark our tutor asked me on Facebook how it had gone. I said I thought I’d got about 3 in 4. When the results came through – in only about 15 minutes, mercifully – it transpired that I had 78%. The passing grade is 64. I am a Certified MySQL Developer.
Which is what, exactly?
It’s like this. Once all the important knowledge was kept in wise old people. That’s what the word “wizard” originally meant: Old guy who knows things. Later, with the invention of writing, far more information could be kept within books. But in this information age in which we’re living, the vast (vast vast) majority is kept in databases. They are the electric libraries, the quiet machines behind the scenes of every modern technomarvel. And that’s how I ended up here, basically. MySQL is as important to modern Web design as HTML itself.
And on the way home I attended a public meeting about technology and the arts, part of the campaign to make Galway the European Capital of Culture in 2020. Asked for suggestions on the theme of a digital city, I sketched out an idea for an app so spontaneously that it took even me by surprise. A good idea? I can’t tell. I was very tired by then. Some great ideas come when you’re tired, but so do some great hallucinations. I can only say that it’s simple – so simple that it has to be either brilliant or obvious. The difference, I guess, being whether someone else has done it already. Such is the fine line between stupid and clever.
But it would be great to do, I hope they take me up on it. And why wouldn’t they? I’m an Oracle certified database developer. That’s like a wizard from the future.
So what was the Vatican’s response to Ireland’s historic vote for marriage equality?
Slightly muted, somewhat bitter, and more than a little enlightening.
The Pope himself said nothing publically, presumably not to appear fallible. It was left to close deputy Cardinal Pietro Parolin to make this odd but revealing pronouncement:
The Irish vote, he declared, was a “defeat for humanity”.
The decision of a majority to accept and cherish a minority? To me, that is the triumph of all that is best about people, humanity at its absolute finest. It seems that when the Catholic Church uses the word “humanity” it means something quite different.
Itself, I suspect.
A 2,000 year old all-male global institution. For sure that’s an organism of a sort, able to preserve and replicate itself successfully. But its goals and its needs, its triumphs and defeats, are not humanity’s. Life, but not as we know it.
I finally went to a doctor, something I hadn’t done in years. Why not? In case I was ill of course. This is what stops people (OK, men) seeking help – the fear that we might need it. If you went there to get health booster shots or something we’d turn up every week. But to discover that you might really have a flaw, a weakness… Well, many men would sooner die. Many do.
I had a strange little spot on my leg. Every time it seemed to grow bigger – which was about every time I looked at it – I thought Oh no, should have seen a doctor before now. I’ve probably left it too late. I’m gonna die.
And then I’d ignore it again, for I am a manly man.
And thanks to getting myself a fantastic new phone for Christmas, I’d discovered another way I might be going. This is not a spin they put on it when they promote these health and fitness apps, is it? Get the new BitFit, find out you’re gonna die! My one has a doobry that can measure heartbeat. It tells you what is “normal”, and what is not. Mine was not.
But by using my kneecap for leverage I finally got myself through a surgery door. And I’m so glad I did. The doc was nice and soon put my mind at rest. Yes that heart rate is quite elevated, she explained. But this means you’re badly unfit, not that It’s About To Blow. The thing on your leg you thought might be a death sentence for the last few years? That’s an old insect bite.
Well, she used words like “tumour”, “cyst” and “fibroid”, but thankfully it had nothing to do with cancer or cystic fibrosis. It was just a scary name for a weird kind of scar which, despite being in Latin, is perfectly harmless.
And she gave me anti-inflammatories to deflate the knee. As I suspected it was just a wrenching of the cruciate ligament, which in layman’s terms is the thing that keeps the lower end of your leg attached to the top end. I was very relieved to hear that surgery is not usually needed for this. Seriously, there are countless parts of my anatomy I would sooner have cut with sharp knives than my knees. But just in case, I’m on a waiting list to see a specialist too. And with the state of our medical service, there’s every chance that I’ll be completely healed before my appointment! Excellent.
Speaking of healing… It’s a week since the Charlie Hebdo massacre now. I wonder when the healing will begin there, or what form it will take. Nothing that’s happened since inspires much optimism, does it? We’re still going through the inflammatory reaction. A display of formation hypocrisy by the world’s leaders, evil and brainless “revenge” attacks on mosques, and of course promises of tough new laws right across Europe.
What, because the murderers took advantage of a loophole in the current anti-murder legislation? Do they think if a law is broken that means it wasn’t strong enough? It’s a kind of superstition, a fetishisation.
“Terrorism happened, we must make laws!”
“But terrorism is already illegal.”
“Well then we’ll make some other things illegal!”
And so there will be new powers of surveillance, new crimes of saying things that might lead to terrorism – the attack on public speech balanced by an attack on private speech. Perhaps it’s like the man with the hammer; for legislators, a problem is a thing that isn’t illegal yet.
The best response to terrorism is to do what you were going to do anyway.
Well Happy New Year all you walking people, with your legs. I’m sorry, perhaps my frustration shows. I did my knee on New Year’s, thanks to wild and frenzied dancing at Roisin Dubh. Someone’s frenzied dancing knocked a drink over, I ambled past and slipped on that.
It’s funny how you know, even before you hit the ground, that it’s injury time. “This,” you say to yourself as you start to descend, “will not end well.” Something to do with the angle. And the wrenching. And the popping.
It was painful for a while, but now it only looks painful. And oddly, something like Van Goch’s Irises. I’ve made good progress, though it did mean being confined to bed for a couple of days. OK, there are worse places to be confined. All other places. And I was very fortunate to have a friend staying, who could mop my brow and bring soup and generally indulge me. But then spoiling someone is actually very nurturing. If your GP gave you a medically unnecessary backrub now and again, maybe a scatter of gentle kisses, far fewer people would need alternative therapies.
Healing is not something a doctor does to your passive body like a kind of mechanic, but it’s not a thing the body can entirely do for itself either. Medicine is a social interaction, between your body and the community it belongs to. Those around you influence your health in countless ways, from pooling their resources to care for you, to simply making you feel cared about.
Few things are more conducive to health and happiness than the assurance that you matter to other people. Why does fake medicine work so often? Because it makes you feel like someone actually wants you to get better. That’s why it’s called the placebo effect, meaning “I’ll please”, not the “take this pill and go away now you walking talking irritation” effect.
Well, more a redecoration. I happened on a nice-looking WordPress theme and tried it out. I like that it’s distinctly more modern in feel. I’m not totally gone on the current trend to areas of dead flat colour, but it’s healthy to experiment. Expect it to change again, as I try on themes like frocks.
And in the ripe plumpness of time I will give this place a theme of my own. The design itself is not the problem – I’m practically specialising in WordPress sites these days. But with these free hosted blogs they actually charge you to use your own code. I’m already paying them to use a custom URL, so it’s beginning to seem more sensible to host the thing myself. I’d learn more too, and have a lot more flexibility.
But first I have far more important websites to build. And as I am doing them for money now I will have to make a site about making sites – a pretty darn good one, needless to say. Plus my cartoon site is so technically outdated as to be an embarrassment – HTML 4.01. It doesn’t sound like it should be so different from the latest HTML 5, but between those two versions fifteen years elapsed! The practice of Web design has undergone a sea change – from static files to dynamic databases, crude table layouts to complex cascading style sheets. Using HTML 4.01 on my own site now is like being a cordon bleu chef while secretly living on pie and chips.
So I guess this is will stay a hosted WordPress blog for a while to come… But then there hasn’t exactly been a lot of posts in the last year, has there? Or for that matter, the year before. This is a good thing, in that it means I was doing something more useful than writing without being paid. As regular(!) readers will know, that thing was an MSc. That’s all done of course (bar, excruciatingly, my final grade), so perhaps I’ll be writing a bit more often now while I decide my next move.
