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.
First they unplugged your phone from the wall, rolled it up and stuffed it in your pocket. Then they took your camera off the shelf, shaved it down to the thickness of a playing card and slid that inside the phone. They crammed in your Walkman too. Your address book and appointments diary. Pager, torch, pedometer, radio, dictaphone, bookshelf, TV, PC, satnav, even your wallet now. In short, just about any piece of equipment you might want to carry around in your pocket finds itself inexorably sucked into the single über-device we still, for want of decision, call a phone.
There is a good one-word explanation for this: Synergy. All these functions share at least some and often many requirements – a visual interface perhaps, network connectivity, speakers, data storage, computational power of course. The user benefits greatly by not having to carry multiple versions of essentially the same hardware. Imagine how we’d rattle if we did. It wouldn’t be worth the effort or expense to make most of these things pocket-sized. Make them a function of a universal gadget however, and the synergies flow.
The one that really clinches it though is power. At first it may seem counter-intuitive to put all our electric eggs in one battery basket. When one goes flat, they all go. But consider the alternative: If all these things needed charging separately there would be one or more plugged in pretty much all the time, completely undermining mobility. The greatest synergy of all is that you can charge everything at once. In many respects what we’re really carrying around is a fantastic little power source with some peripherals attached to it.
With this in mind, it’s easy to understand why smart watches have never really taken off. They cannot as yet replace the smartphone, and carrying both means you duplicate many functions while adding few. Yet they have to be charged as often as phones or more, doubling your inconvenience for very little palpable benefit. While you might embrace one enthusiastically as the badge of an early adopter, it won’t be so long before you find you forgot to charge it. The simple fact is, you don’t need a smartwatch.
I’m sure the Apple Watch will be more successful than any that has gone before, but that isn’t saying much. It may serve as a status symbol – at those prices, it is hard to imagine what else it could serve as – but in its current form it’s another niche product like Apple TV, not the next Apple game-changer. Here’s why:
To ever be more than an expensive optional accessory to the smartphone, the smartwatch has to turn the smartphone into its optional accessory.
Note the word optional. The market-redefining smartwatch will have to do all the indispensable communication things – texts, emails, social media updates and, last but still not least, voice calls. But unlike the current Apple offering, it needs to do it without an attached smartphone. Otherwise it’s really more of a burden than a blessing. The smartwatch will be successful when it’s the one device you always want to bring with you. Your wrist is the natural place for that.
This will not mean the end for the unit we still call the phone. We’re unlikely to abandon such a convenient, multifunctional device while it still has irreducible advantages: A far larger screen interface, room for more and better sensors, more data, and of course much more energy. But we can reimagine the phone now. Specifically we can imagine it… without the phone.
If your watch can receive your calls and data, then the “phone” no longer has to be an always-on device. It can be more like a small tablet, used for apps, browsing, media and other roles that benefit hugely by the larger screen and greater processing power. But like a tablet it only needs to be powered up when you actually want to do those things, putting it in the class of devices with battery life measured not in hours but in days. And this introduces a very interesting possibility: it could act as a power bank to the watch. You’d worry a lot less about running out of juice on the road if your communication device could be topped up from its energy-rich companion. That’s not just a synergy, it’s symbiosis.
And this is not the only opportunity offered by taking the phone out of the phone. The limitations on the dimensions of your pocket device have always been dictated by its phone functions. Giants like the Galaxy Note 4 or iPhone 6 Plus push at the limits of what most people can comfortably use one-handed. Go much larger, and you cross the boundary of what fits into pockets. Shifting the communication function to the watch though means you no longer really need its companion to a be go-everywhere compromise. It can, literally and figuratively, be whatever your pocket allows. You could even have more than one of them – a slim one for tight pants and a big one for a bag, anything from a born-again flip phone to a workhorse device with a pen or keyboard. What the phone will evolve into is a set of optional extensions for your wristwatch. These may reproduce some of its functions and add others, but their essential purpose is to allow you to choose the best interface for the way you want to interact with it.
All this awaits the creation of a smartwatch that really is usable for voice calls and data, yet has battery life to last comfortably through the day. It’s a tall technological order, and the (first) Apple Watch certainly doesn’t achieve it. What it may achieve though – indeed, perhaps what only Apple can achieve – is an end to our culture’s resistance against talking into your wrist like a cartoon character. That alone would be a great stride toward the next mobile revolution.
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.
OK I’ll buy one.
Best to be clear about that from the start. After viewing today’s IFA Berlin presentation, I’m already planning to push substantial amounts of money onto the nice Korean people. So anything I say from here on cannot be regarded as truly neutral. Spectacles set to rose.
That being acknowledged, let me tell you why I want to spend excessive money on this excessive device.
The Galaxy Note has quite literally been my constant companion for the last three years. I bought the original one the day it went on sale in Ireland, used it in countless ways for both work and play. I’ve watched it grow year on year – the more refined Note II, the seriously powerful Note III – and with each new model, I have…
Stuck with the original. Though every iteration was more desirable than the last, it would not have been genuinely more useful. Not enough to justify starting another long and expensive contract anyway. The industry may love conspicuous consumers, but for most real customers a phone of this quality is a long-term investment.
And with the Note 4, the time may have come to begin again.
I don’t claim to be overwhelmed. Not a single one of the wilder rumours panned out. The Note 4 has a powerful 3GB of RAM, but not a revolutionary 4GB. Standard storage is still only 32GB instead of 64. Even the S4’s weatherproofing, considered almost a given by the rumour mill and greatly to be desired on such an expensive device, doesn’t seem to have materialised. On the other hand, we can be glad that some of the legends did not come to pass. Foldable AMOLED screens are an exciting technology with many possible applications, but would you really want to write on one? And though part of me would love to see the screen size creep up to 6” and beyond, it’s probably best to call a halt at 5.7”. A phone has to fit in pockets.
Rumours and wishful thinking aside, the Note 4 lives up to expectations. Specifications have been enhanced by respectable margins pretty much across the board, and there are a few highly significant improvements like high-speed charging and an ultra-low power mode that can keep it ticking over for a fortnight. Also the ghost of plasticky tackiness seems finally to be exorcised, with a slender metal rim and grippy leather-look back (now without the questionable faux stitching) lending it the air of a precision instrument like a classic SLR camera. At last the looks live up to its cost and quality.
If the Note 4 lacks anything it is one knock-down new feature to get excited about, but perhaps this is not surprising considering the nature of the beast. We’re long past the early days of the iPhone when each year’s model brought another feature that had obviously been missing. The Note already does about everything any other phone does, plus a lot of other things as well, all while pushing the form factor to its limits. Therefore Samsung tends to add its most experimental technology not to the flagship device itself, but to a special edition.
That bill is consummately filled this time by the Edge version with its cute auxiliary interface down one side. It’s an interesting and useful enhancement, but I’m not sure if this special-model strategy is paying off for Samsung. No doubt they worry that adding a controversial feature could raise costs while actually reducing the phone’s potential market, but I think if they’d been daring enough to put the edge display on the standard version it would have made the phone grab attention everywhere it was seen in use. Though it’s a cool extra, I can’t see myself paying extra for a version that has it. Indeed I’ll be a little surprised if any carrier even gives me the option.
The other way Samsung “adds” features of course is by offering new peripherals to integrate with. This time we see a bigger and better Gear watch, which I like but am neither rich nor ostentatious enough to buy. More excitingly, collaboration with Oculus brings a Gear VR headset – simply slot the Note 4 into a pair of goggles and you’re in another world. A technological tour de force by any standard and a sure headline-grabber, but not a reason for me to buy.
What does it for me is the solid improvements to the features I use regularly. More than once I’ve upgraded a phone basically to get a better camera, and with 16MP and real optical image stabilization, the Note 4’s is streets ahead of the original’s (already excellent) 8MP offering. And with a resolution breaking 500 pixels per inch and super AMOLED colour and contrast, its screen outclasses not just the fine precedent of the original, but every display available today.
Of most importance to me though are the enhancements to the Note’s core differentiation – the S Pen. This may mean little to anyone except artists, but there will now be interchangeable tips to adjust the pen-on-paper feel. Best of all the new pen will have 2048 levels of pressure sensitivity, the equal of professional graphics tablets. Do you really need that many levels to draw and annotate? No – but on the other hand you can never get too much sensitivity. The more nuance a pen is alive to, the more realistic the feel and the results.
I can’t see owners of the Note III rushing out to buy this, unless they are either blessed with excess wealth or cursed to own the most expensive phone available at any given moment. To them it would be only an incremental upgrade. For those of us who still have the Note or Note II however, decision time has come. And maybe it’s time for you too, if you haven’t yet sampled the delights of a device that, besides being everything a smartphone can be, is also a fine notebook and sketchpad.
The original Galaxy Note was a hard act to follow, so much so that it has taken three generations of enhancement to truly leave clear water. But a significantly better pen and camera make the Note 4 a significantly more useful tool.
So goodbye Windows XP. You know, I’m actually sad. Since it came out in 2001 I’ve grown from being indifferent (“Windows 2000 in a dress”), through slightly awed (when Tablet PC edition introduced handwriting recognition that actually worked), to comfortable and complacent. For a long time there, XP was just the way things were, an everyday ubiquitous tool. After using it for over ten years there was very little about it I couldn’t mend, maintain, or make better. And now Microsoft have declared those skills redundant.
You can see their argument: They haven’t made anything out of XP for years now. Well yes but…
The thing is, there’s a big secret about IT. In the terms I’ll be using in the exam I should be studying for right now, information technology cannot provide a strategic advantage (Carr, Harvard Business Review 2003).
In lay terms: IT is for suckers.
When it all began, people thought that computerising a business would mean radically improved efficiency and so lead to greater profits. That seems to make sense, yet somehow it never did. You do increase efficiency, sure. But that almost never translates into more money. This is because very quickly everybody was able to invest in the same technology, levelling the playing field again.
Only now to keep up with your competitors you have to keep on investing in your system, on a hamster wheel of hardware and software upgrades. That was never such a problem with filing cabinets. So bizarrely the technology may actually cost you more than you’ll ever save through improved efficiency – but you need it now just to stay in business. Nobody makes money directly from IT except the people who sell you the IT; Microsoft in particular have made billions and billions and billions and billions.
So I think they kind of owe us one.
It’s not that I don’t want to upgrade. I have a Windows 7 computer too and I quite like it. It seems fussy compared to XP, but it has some good points. I actually like a lot about Windows 8, despite its cool reception. Though Microsoft seem to have lost all sense of direction, their stuff has never looked better.
No, upgrading is just out of the question. Between my own devices and ones I administer for my family I am looking after four XP computers. At over €100 each, that’s far more money than I am either able or willing to give to Microsoft just now. And even if these computers can run Windows 7 or 8, they will not run it well. So I’d be paying them money to convert PCs that are fine into ones that are annoying.
Is there another way? Well yes. In a word: Linux. Two, possibly three of these computers will become Linux boxes now. High time too. But that is not for everyone, and I will want at least one of them to be able to run non-Linux applications like Photoshop. Can that be done?
I’m going to see, I guess… While continuing to use an unsupported operating system is not a course of action I’d recommend to anyone who doesn’t want to get their computer invaded, held to ransom by criminal gangs and used as a spam-vomiting zombie, how would you go about it?
Well there’s one safe way…
Don’t go online. It sounds a bit crazy now I know, but some of us still remember how computers were actually quite useful even before the Internet. If there’s a job you need to do that doesn’t actually require a live data stream it is perfectly feasible to disconnect. Your XP computer will be perfectly secure – forever!
(Well, you’ll still have the problem of moving your files onto and off it without getting it infected the old fashioned way.)
But if you really have to go online – say, you have no other computer – there’s…
PLAN B [>>>Not Recommended!<<<]
1. Stop being an administrator. Ridiculously, every account on an XP computer is an administrator by default. That means you can do pretty much what you like to the system. Unfortunately it also means that if you catch a virus while logged in as administrator, it can do pretty much what it likes too. It is far, far more secure to use a Limited Account. You may have to log in as admin to install software or other such tasks at times, but the security will be worth it. And if this is a family member’s computer that you mind for them, there’s a good chance that they won’t see any difference. Simply go to the User Accounts section of Control Panel and change the account type.
Unfortunately though there is some software that doesn’t like running without complete privileges, Adobe Photoshop being a particularly egregious example. If – like me – you need to work in Photoshop and then email the results, seriously consider logging out of your admin account and into a limited one before you go online. Ridiculous I know – Adobe and Microsoft really need to share the blame for that one – but far safer.
2. Tool up. When XP support goes, updates for Microsoft Security Essentials go with it. So if this is all you have in the way of antivirus you’ll need to upgrade. Currently I’m testing the different free options that are out there, and I’m really liking Bitdefender. This because it scores almost if not as well as the best available when it comes to detecting viruses, but demands very little of your system’s resources. In fact it seems significantly lighter than even Microsoft’s minimalistic solution, despite offering far better protection. Wish I’d used it years ago now…
3. If the OS can’t be updated, at least keep all your application software patched. A great tool to help with this is Secunia’s Personal Software Inspector, which checks the versions of what you have installed against its database of the latest ones, and lets you know when there’s an update you need. Sometimes it can even do the updating for you.
Apart from that, the usual rules still apply – just more so. Never use Internet Explorer (the version XP has is hopeless outdated now anyway), use Firefox or Chrome or… anything else. Make sure the device you use to connect to the Internet has some level of inbuilt protection like an NAT firewall. Only connect to known secure networks, not random Wi-Fi signals. Avoid visiting criminal corners of the Internet. Don’t install anything, ever, unless you’re absolute sure it’s safe. Be careful out there.
Roscommon. After driving for an hour we stopped at a garage to ask directions, and I noticed this. It dates from 1937. Chassis and V8 engine by Ford. Coachwork by… a blind guy with a headache, apparently. It’s long retired of course, but the garage owner said they still take it out for runs occasionally. Only short ones though, as it does about four miles to the gallon. The thing must’ve had to carry more petrol than water. Which is sub-optimal.
I’ve been talking about PHP a lot recently, but so far I’ve said little about what it is and how it works.
So, What is PHP?
PHP files are a lot like HTML web pages, but also contain these PHP instructions or ‘scripts’. In normal Web browsing, the user requests a file by clicking on a link to it. If this is HTML it is sent directly to them, to be rendered on the screen as text and images by their browser. If it’s a PHP file however it is sent first to the PHP interpreter on the server. Here the scripts it contains are executed and the results – which are always HTML – inserted into the document where the script used to be. Now entirely HTML, it is sent to the user’s browser to be rendered in the usual manner.
So What Can They Do There, These Scripts?
In this way PHP can take requests from a website user, turn them into SQL or some other database query language, and format the results of the query as HTML to send back to the user’s browser where they can be displayed. As I mentioned in the previous post (and the one before that), this is a hugely powerful and flexible technique that can be used for untold purposes. While pages of search results would seem an obvious example, that’s just the nursery slopes. Systems as complex as Facebook are built in PHP. And systems that are good too.
¹Don’t worry if you don’t, there is much you can do with PHP without knowing any programming at all. Thanks to the likes of WordPress, Drupal, Joomla and many more, you can install and run a PHP-based site without speaking a word of the language.
When considering what Content Management System to deploy today, one question needs to be answered first.
Why not just use WordPress?
WordPress was created to be the software behind the popular blogging service¹, and only a few years ago would have been dismissed as little more than that. It was never conceived as a general-purpose content management system, but designed with the singular goal of getting a person’s words and pictures onto the Internet simply and quickly. The thing is though, that is the core functionality of content management. Do it particularly well, and you’re onto something.
Combine that solid core with the ability to add functionality and you’re really onto something. Though invented for blogging, conversion into a different sort of content management system – say a gallery, a forum, or an e-commerce store – is available through third-party plugins. There is a staggering ecosystem of (the last I checked) nearly 29,000 of these. Consequently WordPress has become the most popular CMS in the world. And not by a margin – almost by an order of magnitude. Sixty percent of all content-managed sites use WordPress, one in five out of the ten million most popular sites on the Web. I’ll give that a second to sink in.
But by the same token, using something so well-accepted feels almost like copping out. We’re students of this technology, we’re assumed to be on the cutting edge. What’s the point in being just part of the crowd? There are innumerable content management systems out there. Many use the same attractive PHP + MySQL open source formula. Others again are based on ASP, Java, Perl. Some are even designed specifically to create online galleries, which is certainly closer to what our client needs than a blog is. But while these are worth looking into, the requirements go well beyond just the presentation of images. There is a great deal of text that needs to be easily and well presented, and a dedicated gallery system might not envisage that. The client also needs to manage membership, promote upcoming events, and automatically archive past ones. We will need something extremely flexible, and WordPress scores highly there.
But it’s not alone. Joomla¹ is also designed to be extended – it seems particularly rich in image galleries – and unlike WordPress it was a general-purpose CMS right from the start. It will have to be on our shortlist, especially as the team has had some experience with it in the past. Perhaps the biggest mark against it is that, with only around 6,000 available extensions – about a fifth of what WordPress offers – it just seems less likely that the functionality to meet our client’s needs will be readily available.
Initially, my instinct was to use Drupal. Also designed from the start to be a universal content management system, this one has put even more emphasis on flexibility. So while with WordPress you can have a usable blog virtually the moment it’s installed, Drupal is at first confusing – all you have is a framework, with few features except basic database and user management. Useful functionality is added by downloading and installing “modules”, over 25,000 of which have been contributed by the community, very comparable to WordPress’s 29,000 plugins.
But while plugins and modules might sound like two ways of describing the same thing, there is an important conceptual difference. WordPress extensions are very much goal-orientated. If you wish for example to add gallery functionality to your site, you compare the galleries available and plug in the one that best suits your needs. Drupal modules are function-oriented. To add a gallery, you consider what additional functions it would actually require – image management, display, cataloguing and captioning for example, possibly also resizing and retouching – and add modules for those functions. You’ve got a huge smorgasbord of features to avail of, what you mix is up to you. Such a level of flexibility is both challenging and exciting. A much more precisely customised result should be possible with Drupal, and this is why it is considered by some to be the best CMS of all. But the learning curve is also infamously steep (see illustration). I have to admit that this is part of the attraction. I’ve built several sites based on WordPress and it presented little challenge; the Drupal one I started over two years ago is still far from finished. It definitely represents the greater learning exercise. But that is not the objective today. Even if the team could become sufficiently skilled with Drupal within the timescale, it seems likely that that time could be better spent.
Plus, with Drupal skills being relatively hard to come by, future site maintenance would inevitably be more difficult. Perhaps a clinching argument in favour of WordPress is that, as by far the most popular CMS in use today, future maintenance and improvement should not be a problem. Indeed as an open source tool with both a strong community and the backing of a commercial interest, WordPress would seem to combine the best of both worlds in terms of support.
I wish we could use all three just to see which came out best, but the postgrad workload is too heavy for that. We should be making our decision shortly. For now though, my money’s on WordPress as the one most likely to deliver the client’s requirements without excessive drama.
