Linux For The Normal

That’s all very well, but why would you – an ordinary person with no particular ideological bent or business need – want to use Linux? Obviously if you’re reading this you’ve already got a perfectly good computing device of some sort. It will have an operating system from Microsoft or Apple or Google that you’ve spent time – perhaps years – getting to know. You may have spent a lot of money on software that won’t work with anything else. Why would you even dream of starting over with a whole new system?

I admit, this applied to me too. Now and again I would install Linux, marvel for a while at how all that great stuff was available for free, and immediately go back to the system I paid money for. Not because it was better, but because I knew it better. This catch-22 of not using Linux because you don’t know it and not knowing it because you don’t use it could go on indefinitely, always keeping you from taking that last step over the threshold. Unless and until a situation arises where nothing but Linux will do. And this is what happened to me recently.

Twice in fact.

The first case was a family member who’d acquired a PC with no working hard drive. He could’ve bought a copy of Windows for about €100. But why? He didn’t need Windows in particular, hadn’t spent years learning its little ways. If he was going to get to know one system, it might as well be the one that wouldn’t keep asking for money. On top of this his main reason for getting the computer was to go online, and for that Linux could not come more highly recommended. Viruses that attack it are too rare to seriously worry about, and it is designed in such a way that if one did get on it could do little harm. So we resolved to set him up with Linux.

And there was my own case. As I was telling you earlier, I recently built a system with more memory in it than you could conceivably shake a stick at – 16GB. However, the ordinary 32-bit version of Windows can’t make use of anything like that much. Just as bigger cities need longer phone numbers, you need a modern 64-bit operating system if you want to call up a serious amount of memory.

And here’s an annoying thing, there is no Windows upgrade path to the 64-bit version. So adding RAM can mean you have to buy a whole new license. For about €100.

Or you give Linux a go, and never pay for software again.

Hmm.

So there are people in some quite ordinary situations who could save considerable money by using Linux. And needless to say, it has other advantages apart from low cost and security. It’s also the most customisable, flexible system. There’s so much sheer choice in fact that it can seem a little intimidating at first, so next time out I’ll talk about where to begin.

Linux Crisis?

480px-LinuxVollwaschmittelPackung
It even runs on some washing machines

Linux – it’s like a shark or an iceberg. Most of it’s below the surface but it’s moving fast and you really ought to know about it.

The majority of people, if they’re aware of it at all, probably think of Linux as the non-commercial alternative to Windows or Mac favoured by people who use computers less to get things done than because they actually enjoy it. Which is a shame in a way, as it gives a wholly wrong impression of its significance. Linux is so much more than an operating system for nerds. Indeed you probably use it yourself, every day. Each time you visit a website the chances are good that you’re talking to a computer running Linux. Smart devices in your home like satellite boxes and DVRs, even TVs now, use Linux. If you have an Android phone, that’s based on Linux. Governments are adopting it, and it is far and away the favourite operating system for the world’s most powerful supercomputers.

So it should be surprising that on the workplace desktop – still the biggest, most visible, and most lucrative computer market sector – it runs a very distant third. How come?

Operating_systems_used_on_top_500_supercomputers.svg
Linux conquers the supercomputer (Author/Wikimedia/Top500.org)

Counterintuitively, because it’s free. After all the PC is not ruled by Windows and Mac OS because they’re cheap. Rather it’s because people can make money out of them. Huge ecosystems of supporting industries have grown around these computing platforms – software, hardware, services, training, maintenance, publishing – in no small part because there was a key partner there offering support and leadership.

How do you make money out of a system no one owns? With whom do you form a partnership? How can you be sure, when no one’s in charge, that it’s going to develop in a direction that will suit your business? It’s tricky.

Unless of course you take a leadership role yourself. It seems the best way to make money from Open Source Software like Linux is often to step up and be that key player. This is what Google did with Android, making it the world’s most popular phone OS. Or Red Hat, whose version of Linux is one of the most successful systems in the server sector. Each brought their own business model; Google of course is ultimately selling advertising, Red Hat its expertise and support.

If anyone is going to turn Linux into a household – and an office – name it is surely Canonical. This is the power behind Ubuntu, the most popular and user-friendly desktop version of Linux so far. And their vision doesn’t stop at the desktop – nothing worthy of the name could these days. In recent weeks they’ve launched Ubuntu editions for tablets, phones and TVs. It seems they plan to have devices running their software in every major market sector.

Ubuntu TV – It’s a lot like Windows Media Center except for the giving money to Microsoft part.

It’s an extraordinary ambition, and if they can pull it off then Canonical/Ubuntu will be up there with the big girls, sitting proudly alongside Google, Apple, and Microsoft. But can such a fabulous commercial edifice really be built on open foundations? So much of Linux is being developed by people who work for competing organisations – or who aren’t being paid to do it by anybody.

Indeed community disenchantment may already be starting to show. Ubuntu is no longer flavour of the month. Once hugely popular with the sort of Linux user who doesn’t actually want to reinvent the wheel but just needs something that can be installed and maintained with the minimum of fuss, Ubuntu – and its slightly geekier sisters Kubuntu and Xubuntu – drove all before it. No longer; the flavour now is Mint.

This is a different Linux variant (or ‘distro’, to use the jargon). Indeed it’s very much a variant of Ubuntu, just with Canonical’s more commercial ideas stripped out. (This ‘forking’ is perfectly legal in the OSS world – in fact it’s the whole idea. Ubuntu itself is based on the well-respected Debian distro.) Mint’s popularity though was given a huge boost when Canonical introduced their ironically-named Unity interface.

Some of the resentment of this was silly. Unlike Windows or Mac where the graphical user interface is part and parcel of the system, much of the beauty of Linux is that you can choose – even create – your own. For some however it’s a cause. There have long been two main Linux desktop camps: Gnome and KDE. Ubuntu had been on the Gnome side, so its defection – to a third camp of its own invention yet – was seen by many as betrayal.

English: Screenshot of Ubuntu 11.10 (Oneiric O...
Ubuntu’s Unity desktop, with its great big finger-friendly icons (Photo credit: Wikipedia)

More seriously though, Unity is very clearly a touch-orientated interface. As the name suggests, it’s meant to be similar on all types of device. Rather like Windows 8 this makes it less efficient – or put it another way, more annoying – for users stuck with an old-fashioned mouse. And as Linux tablets barely even exist yet, that means pretty much all of them. For the first time, Canonical were allowing their commercial vision to degrade the user experience.

But that was as nothing compared to the next change. A feature of Unity is that you can find a file or application by typing its name in a search box. If what you type isn’t on the computer, the newest version of Ubuntu continues the search on the Web – specifically, to Amazon.com.

“Crochet Patterns not found. Do you want to purchase Crotchless Pants?”

This unasked-for advertising feels a bit like an invasion of privacy. The building of it right into the operating system feels a lot like a kick in the teeth to the non-commercial ethos that engendered Open Source.

Making money in itself is not the problem. Google, Red Hat, even that old devil IBM make a lot of money out of Linux. Where I think Canonical sail close to the wind is in identifying themselves with Linux more closely than any company before. Independent computing creatives will resent it deeply if they come to be perceived as dupes – or worse, minions – of a commercial giant.

There are two questions here really. The first it whether Canonical/Ubuntu can maintain the goodwill of the wider Open Source Software community. The second is whether they can realise their vision without it. Perhaps they can, but I think it would be a minor tragedy if they did.

One thing over which there’s no question though: Open Source Software can continue without Ubuntu.

____________________________________________________________________________

Next time I’ll talk about why you should try Linux for yourself: Because it’s fascinating, informative, educational – and could save you heaps of money.

All Systems Are Gone

Not Real Organisation Chart

Done. Just submitted my first ever systems analysis of a real company. It’s an assignment, I think it went OK. We (a team of three) freely admit we could have used more information than we had access to, but I reckon we probably did reach useful conclusions about the dangers this little software company faces – and what they might do about them.

Think it’s a good team. Funny reading the report afterwards; even edited together you can clearly see the difference in our styles. The others did things like bringing in detail and applying theory. My part is, well, narrative. I’m writing stories. Which is a little weird, but maybe it works. You need all of that in a report. It just maybe needs to be a bit more… blended. The sudden gear-changes from academic to emotive prose are probably more fun than they really ought to be.

Just one question remains. Why am I doing systems analysis again?

Coffee Break

McCamridges2The window of McCambridge’s is one of the great places in Galway to have coffee. Looking onto the main shopping thoroughfare, it combines all that’s best about walking around town with all that’s best about sitting inside not doing that.

With our weather – and the last time I was here I watched a wooden forklift pallet being blown down the road – it’s a priceless resource.

The name of that thoroughfare by the way is Shop Street. I’ve always liked the excessive literalness of that. The adjoining High Street meanwhile is full of pubs. All we really need is for the banks to be down Arsehole Avenue.

But I must stop avoiding the issue, I’m here to apologise. This has been one of the longest breaks I’ve ever taken from writing here. What siren has lured me away with her haunted song? I’ll tell you honestly. Flagrant geekery. Part of the time it’s been Java. Not the coffee, the programming language. Part of the time it’s been Linux. All of it, in short,  stuff that most people neither understand nor – and here’s the really tricky part – particularly want to understand.

So writing about them in an entertaining way may be a little tricky. But  I will give it a  go.

Coup In Ireland

Noonan

It was strangely reminiscent of that military coup where the signal to attack was, of all things, the Portuguese entry in the Eurovision Song Contest. With coded announcements, the President snatched away from a diplomatic mission, an emergency all-night sitting of the house, and plenty apparently deliberate misinformation, “Project Red” saw Ireland taken over – though not by the military.

If you went by the news coverage, you might be forgiven (a special offer, today only) for thinking that we just escaped the jaws of disaster here. On the contrary – Ireland avoided an acute short-term problem by making an awful long-term commitment. A very, very, very long-term commitment. We were forced into it at what might be termed fiscal gunpoint.

On September 30th 2008 in the wake of the collapse of Lehman brothers in the US, the Irish government pledged to guarantee the banking industry here. Not just the banks’ deposits but all their liabilities – including the vast amounts they’d borrowed from banks overseas to fuel the country’s property speculation bubble. That figure turned out to be truly mind-boggling – over €400 billion. That is more, even after inflation, then all of Germany was forced to pay in reparations after World War I.

You might fairly ask how the government of a small country could hope to come up with €400 billion. They couldn’t of course. It was a bluff, a confident front designed to ward off market chaos and speculation. But if you’re bluffing, you don’t bet the house. The government exposed the country to a liability that beggared belief. Indeed, beggared the lot of us.

It’s been argued in their defence that the industry lied to them, directly, about the scale of their liabilities. That’s true, but they knew damn well that there was something seriously wrong anyway. These banks had been making staggering profits for a decade mainly by lending people money on excessively easy terms, thereby boosting the price of housing, thereby creating demand for bigger loans… Banks had been enjoying a prolonged bonanza, but it was a bonanza of debt raised against assets that no one could seriously argue were not grossly overpriced.

Why had banks not simply raised the price of borrowing, to profit more from less lending – and at the same time moderate demand? Because there was no limit to the amount of money they had to offer. Other banks, in the US, the UK, but mainly in continental Europe, were lending them as much as they could shift. There was a global credit boom going on of course, there was an (originally) quite genuine boom in the Irish economy, and to cap all this there was no longer a national currency to wildly inflate and so damp things down as had happened in booms gone by. Ireland represents perhaps 1% of the Eurozone economy, so even incandescent levels of overheating here were not going to drive up the cost of money. Money was, as odd as this may sound, too cheap. Yet keeping inflation down was the main – indeed about the only – guiding principle of the European Central bank. It, or rather its political masters, chose to pursue a policy which might have been reasonable for the Eurozone as a whole, but which was utterly unsustainable for Ireland.

Some people, mainly politicians eager to share out their responsibility, have blamed the population for borrowing too much, as if economic meltdown is caused by sudden outbreaks of cupidity. Those who borrowed more than they should have did so in the main because banks were quite literally pushing money on them. Like many, I opened my post one morning to find I’d been approved for a loan I hadn’t asked for. Certainly far too many got into property, but the housing boom was not only driven by speculation. Another major factor was that thanks to all this cheap credit, house prices were rising far faster than incomes. People worried – not unreasonably – that if they didn’t buy a house soon they would never be able to afford one. Lenders fuelled the fear with the marketing image of the “property ladder”, the idea that if you wanted any chance of owning a good home in the future you needed to buy a bad one now. Many, many awful houses and apartments were sold – and even more built. The entire Irish banking industry had in effect become a Ponzi scheme, profitable only as long as there was new investment. When the market fell it fell like a lift with the cables cut. In doing so, it called the government’s bluff.

At which point they could and should have said “You got us. Of course we can’t possibly afford to pay that much money. Ever. It’s an insane figure.” And they would have been right of course, we can’t. Even after realising the assets of the collapsed banks and throwing in the national reserves, we’re still left something like 70 billion short. They even had an excellent excuse to renege on the guarantee when it came to light just how much these banks had been lying to them about their assets. They should have known better, sure, but officially they didn’t.

Unfortunately however government needed to pay more than just the billions in bank debt. This Ponzi scheme had essentially become the tax base. Not only was a lot of revenue raised on property sales, a simply ludicrous proportion of the population was by then employed in building buildings that no one would ever actually want but which existed solely to be traded on the bubble market. Without this income the exchequer couldn’t even keep public services going, pay doctors and teachers and police and pensions. But the fact that our economy looked to be (and indeed, was) on the point of collapse meant that the country couldn’t borrow cash on the market at anything approaching an affordable rate. The only institutions with both the money and the motivation to lend to us affordably were those of the Eurozone, the very ones who were to a large degree responsible for the collapse. In return, they held us to the untenable: The undertaking to pay back all the money our failed banks had borrowed to fuel the property bubble. The fear being that if we didn’t, the banks that lent to our failed banks would in turn fail, and so on.

So the Irish government’s gamble didn’t save our banking industry; virtually ever lending institution in the country (honourable exception: the Credit Union movement) went bust. But it probably stopped the European banking system going down like the world’s most expensive set of dominoes.

This is what really rankles. Instead of being punished by the market for poor – indeed, reckless and harmful – investment decisions, these institutions are going to be rewarded just as if they had made profitable decisions. They’ll probably give themselves bonuses. And these rewards will be paid not willingly by the market but unwillingly by the taxpayers of Ireland whose jobs and lives they so damaged. And the taxpayers’ children. And their children, if there’s anyone left here by then. Those of us who had the willpower to resist the easy credit have to reward them, just as if we’d taken it. Those who lost their homes because they could not afford the repayments to these institutions, still have to reward these institutions. Those who now own homes worth a fraction of what they owe on them but who are nevertheless still making repayments to these institutions, will see their taxes go to these institutions. The injustice of it is barely conceivable. Ireland is paying roughly 42% of the cost of Europe’s banking crisis. We can’t possibly do it of course. That’s why the Eurozone governments and ECB cut the deal that all the fuss has been about. To help us.

To help us pay back the money we didn’t borrow.

You may have seen the headline figure, that this is meant to save us €20 billion. Are they writing off some of the debt? No. On no account are we to even contemplate not paying any of that money. The twenty billion is just the difference between the “easy” interest we’ll get from them and a rate we might have paid otherwise. They’re giving us easy terms to repay the debt we don’t owe. Some deal.

This explains why we had to shut down the Irish Bank Resolution Corporation – formerly Anglo – literally overnight. While most of the bad debts of the various failed Irish institutions were still being held by this “zombie bank”, there lingered some remote possibility that a government would have the guts to say “Look, the state has no moral duty to pay back failed private investments. Goodnight.” We almost certainly would have negotiated a deal rather than just pulled the plug of course, but we had that bargaining chip. Instead we’ve cashed in our last chance for freedom. Whereas repudiating Anglo’s debts would not have been technically or morally a loan default – indeed, might have been seen favourably by the markets as the shedding of a liability – there is no way out of our commitment to the ECB. Short, that is, of crashing out of the Euro in flames.

So now we are committed to this vast payment. That still doesn’t mean we can pay it of course; indeed, attempting to will just drive us deeper into recession. We will inevitably default on this, as Germany defaulted on the onerous Versailles treaty terms. It will just be later rather than sooner. The only achievement will be a few more years – perhaps decades – spent impoverishing ourselves to enrich those irresponsible lenders.

The “deal” won yesterday was quite the opposite – a scared and desperate government buying time and in doing so, condemning their country to indefinite economic servitude. Death of the Republic would hardly be an exaggeration. Democracy is effectively suspended; the government we elected to overturn the errors of the last has repeated and even amplified them. We are being dictated to – not by the military, not by a despot, but by an industry.

Inadequatebowl

English: American football positions
As we can see from this diagram, American football is basically a cross between armed combat and noughts & crosses

American football is like rugby with all the bits I understand taken out. Admittedly that leaves plenty to be getting on with, but it seems to consist pretty much entirely of men charging directly at one another. That can’t be the most efficient way to accomplish anything. To make it even more confusing, when I tuned in no one was doing anything at all. I’d heard there were pauses in the play, but hadn’t expected them to last half an hour.

I gather though that the power cut is not an official aspect of the sport. Which is a shame, in many ways it seemed the best bit. Like the half-time show but with far more scope for improvisation. You’d think this would be cripplingly embarrassing to the Americans, having probably their most-watched event globally turning into an advert for inadequate engineering. Fortunately however they can all blame it on the political party they don’t support, thereby avoiding any conception of collective failure. Democracy in inaction.

Is There One Brave TD?

Ballyhea
Click here to see me on Al Jazeera News! (Albeit briefly)

 

It’s often remarked how little Irish people are protesting, despite the cruelty of the cutbacks and the blatant injustice of much of the debt foisted upon us. You could come up with a variety of deep psychological explanations for this, but in doing so you might be overlooking one major factor: The lousy coverage that public resistance gets in the mainstream media.

Case in point, the brave folk of the Ballyhea Bondholder Bailout Protest have been marching every Sunday for two years now. But even when they brought their protest to the ECB in Frankfurt (you’ll remember, I went with them) they hardly won a mention from the press or TV.

Until last Sunday! Finally, they got on RTÉ main evening news. Why now all of a sudden? I think I know: Al Jazeera got wind of it. Would’ve been more than a little embarrassing for the national broadcaster if a story from their own country went big internationally and they didn’t even have footage.

You can see me there in the first few seconds. I’m on international TV! Don’t we look all brave in the January weather? In the Middle East they must think we’re downright superhuman.

But there are ways you can protest without risking pneumonia, with help of Contact.it. Yesterday a judge rejected a challenge to the legality of the government piping money directly from poor to rich, on the grounds that a private citizen does not (somehow) have the standing to take such a case. In his findings though, the judge did mention that a TD would.

So we’re looking for one brave TD. Contact.ie provide an email that will be sent to all of them, it’s just up to you to sign it. A suggested text is provided, but of course you can use your own.

Or you can use the one I wrote, which puts the case a little more starkly:

Dear TD,

We need someone to take a stand. The lending bubble, and subsequent channelling of the nation’s remaining wealth to the very institutions responsible for it, has sent one message and one message only to the people of this country: That we exist, that we live and work, not for ourselves or for the ones we love but purely for the further enrichment of these institutions and their owners; that they now effectively control our lives – and control you, our supposed representatives – as surely as if we were goods or livestock. We are being owned.

We need to reassert the purpose – indeed the existence – of democratic government. For once, a single TD could make all the difference.

Yours sincerely,

Help to stop the madness before the last of this country’s life is sucked away. You can send the letter here.

The Font Of All Typefaces

GoogleFont3

In magazines, you have a freedom of design almost on a par with illuminated manuscript. You can set your headlines in any font imaginable, even one where all the letters are little nude couples demonstrating the Kama Sutra, and run them vertically, horizontally, or at any angle between.

On the Web, you’re more constrained. Snazzy design was not a significant priority when it was conceived as a way to publish academic papers. On the contrary, the choice of font was originally left entirely to the reader. That makes a hell of a lot of sense when the priority is conveying information rather than amusing the eye (and in fact any decent browser still lets you override the creator’s intent and choose the font you find most readable), but of course designers soon wanted more control.

One way to insert fancy lettering is to do it as images. But these take longer to download, and directly conflict with important principles of flexibility and accessibility. Worst of all, search engines can’t index the text in a picture. So though they are used a lot for the headers of pages, images are deeply unsuitable when it comes to the body text.

There is some flexibility; the designer can specify what font they want. But “want” is the operative word – the wish will only come true if the user happens to have that font installed on their computer. While this is OK for a handful of almost ubiquitous “Websafe” fonts like Times New Roman or Arial Black, go for anything more imaginative and you’re taking your chances. There are different fonts installed on PC, Mac, Android, Linux, and so on. If the one specified isn’t there, another must be substituted. The result might look OK, or it might be grotesque.

But hey, it’s the Internet – why not just download a font? The idea looks good at first glance but there are a number of problems. A font is a big thing and takes time to download, so you either wait for it to finish before the text can appear, which would be tedious, or switch to it when the font arrives, which would be ugly and annoying.

What’s more, fonts tend to be expensive and proprietary. It’s a profitable industry, and foundries (many still call themselves that) are reluctant to give their high-value goods away. Thanks to this lack of cooperation, attempts to make downloadable fonts part of Web design have sputtered and died several times already in the medium’s brief history.

And that’s the stage we’re still stuck at, as I was telling a friend a couple of days ago. Afterwards though I decided to check on the latest developments – and I found I was dead wrong. Things have moved fast since I’d last looked. There are currently two “Webfont” services actually up and running. Adobe’s, which you pay for, and one from Google that’s free.

Hmm. I do like free.

So I had to try this. I’ve been (sporadically) working on a whole new cutting-edge website using Drupal and PHP and MySQL and all that good stuff. It’s still a long way from being finished though, and the aesthetic stage of the design, when I get there, must start with a clean sheet. So I can’t be doing experiments on that. In the meantime however I’ve neglected my actual working website. In fact it’s dated to the core now. Standards compliant, sure, but not to standards that people remember now. And the newest material on it must be five years old. But it’s all the showcase I’ve got, and I do actually get business from that site. A design refresh might be just the thing.

So I gave it the Google Webfont treatment. You might find it displays the old sensible face first before the fancy handmade-looking one appears, but once it has loaded you wouldn’t know it’s not a normal font.

The range Google has is still limited, at least when it came to my specific need for an all-cap, comic-lettering style font. The best I found is called “Walter Turncoat”, for some bizarre reason. It might remind too many people of MS Comic Sans, but it bears a surprisingly good resemblance to my real hand-lettering.

It’s not hard to use Google’s free Webfonts on your own site. (If you take care of your own hosting anyway. If you have a hosted blog it can be more tricky and/or costly. I’ve added a few useful links below.) In fact there are three ways: The easiest is to simply add an “@import” link to your style sheet. That way you can change the whole site with just one edit. However that method can cause some browsers to slow down, so the faster way is to add a link to the header of every page. There’s also a technique using JavaScript, but I don’t know of any advantage to that. More details on Google’s page.

It’s true that it seems a little rough. In the illustration I’ve inflated one up to some ridiculous size (350pt!), and you can see that in spite of it being a real vector font the edges are bizarrely complex and jagged. This I guess is an artefact of the compression that makes them load at such an impressive rate.

I’d like to see the roughness improved upon somehow – or perhaps it will be less important as screen resolutions continue to increase – but even with it I think the font gives the site a personality and friendliness that simply would not have been possible otherwise. We are on the threshold of a new era here.

So Where *Do* You Begin?

20130108_010526
A Stonking Motherboard, Earlier Today

Going back then to my guide to making your own computer, it’s at this point that I’m supposed to say something wise like: “Before choosing the parts for your PC, ask yourself what you’re going to be using it for”, or “Decide now how much you really want to spend”. To my mind however, the only sensible answers to these questions are:

A) Everything! And

B) As little as I can possibly get away with.

PCs are meant to be flexible, inexpensive and upgradeable computing machines, so let what you can get be the guide to what you should get; what happens to be available at a good price now. Perhaps memory is really more important than that crazy amazing video card, but if the card is on sale at a great price now, memory can always be upgraded later. Seek bargains, go with the flow. Though bear in mind that by a bargain I mean something that’s cheaper than it usually is, not the kind of part that’s always cheap. Reliability is everything in a computer, so quality is worth paying – or at least waiting – for. Look out for brands with a track record, read all the reviews you can get your hands on.

So you could say that the place to start is wherever you’re at. See a bargain? Start! But from another point of view, your real starting point is the motherboard. Virtually everything else slots or plugs into it – as you may guess from the photograph – so more than any other it’s your motherboard that will define what components you’ll be able to use. It’s crucial therefore to have a nice one. But what goes into the choosing?

One choice is between the two major makers of processors, the chips that sit at the heart of a computer. Intel you will surely have heard of; AMD perhaps not, though they offer the chip design Goliath some degree of rivalry. Indeed – though l may be lynched for saying this – I suspect their David status may help explain their lasting popularity with system builders. Their image is not so sleek and corporate as Intel’s.

AMD have been technology leaders from time to time – producing the first 1 GHz processor, developing the 64-bit architecture that Intel themselves later adopted – but I think Goliath has it all over them just now. Processors have to fit into a socket on the motherboard, the design of which usually changes with the technology. Intel however have just introduced a new generation that are largely compatible with the socket – known as LGA 115 – used by the previous. That means these boards can use processors ranging in price, to go by Dabs.ie, from €35 to almost ten times that much. That is a hell of a range of options.

And that means you can get a cheap one now and upgrade at least once, perhaps more, over the lifetime of that motherboard. Which is exactly the route I chose, purchasing a dual core, 2.7 GHz Celeron G555 – a processor that could by no means be described as feeble –  for only €50. So you may have a particular reason to prefer some other family of processors, but to my mind that LGA 1155 socket is the thing to look out for in a motherboard right now.

But there’s more…
