I borrowed a book from the library today, not sure if I’m ever supposed to give it back! Seriously though, is 24:00 a real time? WHAT ELSE HAVE YOU KEPT FROM ME, WORLD?
Please return this book on or before the 6th day of January, 2012, at Hammer Time.

Just in case this can help anyone on the fedora planet or other, who doesn’t visit fedoraforum.org or ask.fedoraproject.org very often. Admittedly I don’t visit there very often myself. A quick search in bugzilla shows some possibly related bugs.
If you don’t seem to be able to alter the screen brightness in fedora, either with the Fn keys, or through the gnome-control-center, try reinstalling bash. I rarely have the screen brightness on full on my laptop, so when I couldn’t change it on f16, it was ever so slightly annoying! I honestly wouldn’t know what to file a bug report against, so I started searching. First stop was that shiny new ask.fedoraproject.org instance, which led me to forums.fedoraforum.org/showthread.php?t=272500
So with the Fn keys not working, which had always worked previously; and the slider in the screen settings in gnome-control-center having no effect, doing a simple
sudo yum reinstall bash
was the answer.
Update:
It’s listed in the ‘Common F16 Bugs’ here:

Hello there, internet. Sorry I’ve kept you in the dark for a while now, I will try to improve on that in the future. So what’s the situation, you ask? Well, I will fill you in with what GOOG et al. are most likely already familiar with. I’ve returned to Ireland from my home away from home: Québec. I will be back, don’t worry, Canada.
On a more interesting note, I’ve also returned to university to study something of interest (to me, at least) this time. It’s a H.Dip in Software Design and Development, and I’m quite enjoying it. It forces me to do some of the not-so-interesting parts of IT study, while also allowing me to do lots of the fun stuff! For the moment, I’m keeping my head well above the water with regards to coursework, but I fully expect and look forward to things becoming more difficult rather than easier.
As some of you know, my email habits have been somewhat erratic for the last while, while I was getting settled back in here, but by now I feel I’ve dealt with most of the backlog; if you’ve sent me an email (or other online comm), and I haven’t replied, then I’ve probably forgotten about it. Please, remind me, and keep me on my toes!
If you’re following me on any social network or microblogging platforms, you’ve probably noticed that the bulk of my spam is now tagged with [D*] or something similar: this means that the post is being forwarded from my Diaspora* seed. If you’ve got one, add me!! – grdryn@diasp.org
So, being back at university, I’ve sometimes got short periods of time where I’m idle, and it’s time that I’m often not very productive with; so I might be able to use it to find something of actual interest to put here! I will try at least. If there’s anything in particular you would like me to rant/review/talk about, let me know! OTOH, if you want me to STFU, please let me know with equal fervency! That’s all for now folks, expect more boring stuff here soon. I figure the more I write, the more mindless nattering I will obviously do, but it will also increase the chances of me posting something of actual value or interest to someone!

There’s a very interesting project called bitcoin, which has started to gather momentum recently, and pop up in more and more places. Bitcoin is a currency, but it has the following properties which distinguish it from what we might call a ‘physical’ currency:
Here’s a little infomation video from weusecoins.com (CC-BY 3.0)
There is a lot of speculation going on about what will happen next. Will bitcoin be a success or a failure? Will the masses begin to use bitcoin on a regular basis? What will that mean for other currencies? Will bitcoin be able to fit into the current economic model and live alongside the legal currencies of the countries of the world? I’m not an expert on the technology behind it, and I’m certainly not an expert on economics; but maybe that is a good thing. I know that everyone using bitcoin at the moment hopes that it is given a fighting chance, and not just outlawed by governments around the globe. Should a currency not be used to give people control, rather than be used to control the people? It is unrealistic to think that it could replace all of the currencies being used around the world, but I do think it will become quite popular for certain purposes, and it will have a significant impact on the way on-line transactions are carried out around the world.
If you are curious about all this, I would encourage you to try it out. The first step is to download the software, from here. Once installed and running on your computer, you will surely want some bitcoins. Rather than buying some straight away, there are ways to get a few freebies, to get a feel for it and decide if it’s worth your time and/or money (your other money, that is…). You can sign up at bitcoinbonus.com and earn a small amount of the currency just for signing up. You can see that further small amounts can be gained by just shopping on-line through the sites listed on the page. You can also get a tiny amount of bitcoins here, although this wasn’t working at the time of posting. The coins are then yours to do as you please with. You can buy goods or services, or sell your bitcoin for legal tender. If you want more bitcoins, you can offer goods or services to people, or buy some at an exchange. For those of you with high-end GPU’s, you can try to ‘mine’ bitcoins (think mining gold, only on your computer), although I think that unless you have a lot of resources, this really isn’t worth it.
How this will eventually turn out is anybodies guess, but I think bitcoin is destined to become increasingly more popular and controversial in the not-so-distant future. If you have any thoughts on this, let me know in the comments!

Since I started using GNOME 3 a while back, one feature that I’ve wanted to see is an option to have certain programs start up when I login. Unfortunately I haven’t had time to look into this until now, and a quick look in the release notes pointed me in the right direction. There are two ways of doing this; neither of which I find very obvious, and both do essentially the same thing. The easiest way is by using gnome-session-properties. Unfortunately, this is something that the shell in GNOME 3 doesn’t seem to know much about. Entering it in the search bar in the shell doesn’t provide anything useful, apart from a wikipedia or google search possibility. To open the dialog, we must either open a terminal and enter gnome-session-properties, or hit the trusty Alt+F2 and enter it there. At this point, I would like to point out that the Alt+F2 command launcher now has tab auto-completion (I’m not sure if that was a feature before or not, but I’ve only noticed it now)!
As you can see, this presents us with the familiar Startup Applications Preferences dialog, where we can add/remove applications to our hearts content! As you can see from the screenshot, the first application I added was RSIBreak. This is a handy little utility to help prevent Repetitive Strain Injury.
The alternative way to add something to startup on login is to manually create the.desktop files in ~/.config/autostart. Some examples can be found in /usr/share/applications.

Welcome to my new blog! As you can see, it isn’t new at all. It’s the same blog as before, just with a cool new domain name.
The new domain is something I’ve been thinking about for a while now, not so much for the blog, but to give me more control over my email address. My main email address up until now has been a free ‘@gmail.com’ one. With my own domain, I can use my new address just like gmail, using google apps, but if for some reason in the future I would like to move away from that provider to an alternative, I have that flexibility. Reasons for moving away from a provider could include anything from a CEO shooting elephants, or even just a competitor comes up with some cool new feature.
For those of you who didn’t catch it, the reference to the CEO shooting elephants, is related to the debacle caused by Bob Parsons, CEO of GoDaddy.com, causing many people to look for alternatives. One such alternative that I would like to recomment is gandi.net.

Today, being Day Against DRM, I thought I would write a little bit about it, and the reasons why I think it is severely flawed, both in reasoning and implementation. DRM stands for Digital Rights Management, but as the campaign at DefectiveByDesign.org points out, a more apt description would be ‘Digital Restrictions Management.’ Digital content providers (e.g. Amazon, Sony, Apple) use DRM to limit the ways you can use the stuff you buy from them (e.g. Music, eBooks, DVD/BluRay). This is why we say that it is defective by design. A decision is made to encumber the content or device with restrictions.
The first thing to note about DRM, is that DRM is not the same as copyright law. Granted, it is often used to ‘protect’ copyrighted works, but it does not respect the rights of you, the person purchasing the works. I believe Karen Coyle puts it best: Where copyright law is an expression of “everything that is not forbidden is permitted,” DRM takes the approach of “everything that is not permitted is forbidden.” This means that you have very little control over how you use what you are spending your money on. Imagine if you went to a pet shop and bought a goldfish, and the seller tells you that you can’t put the goldfish in any other bowl than this bowl, and you can’t give it away when you are bored of it (not that you could possibly get bored of a goldfish!). Now I’m not saying that the bowl the petshop owner provided you with isn’t suitable for the goldfish, but maybe it doesn’t look nice in your living room. Or maybe you move house, and your new abode is furnished with one of those huge tanks built into the wall! DRM doesn’t take into account what may happen in the future, it locks you into specific devices: who says you won’t want to move on from your current Amazon Kindle ebook reader, when a fancier equivalent comes along in the future? DRM will prevent you from transferring the goldfish ebooks you already own on to it.
This is an unacceptable restriction. Digital technology has opened so many new possibilities that are obvious for all to see, but media providers want to restrict it as much as possible, so that they are in control and can take as much of your money as possible. You buy a physical book, you read it, you enjoy it, you add it to your bookshelf. At any point in the future, you can come back and indulge yourself in the wonder that it brought you when you first read it. You own and are in control of this book. You can donate the book to a library, share it with your friends, give it away, even resell it! The information will never die, the knowledge will be passed on for future generations to enjoy. We are still marvelling at books written thousands of years ago! Now, look at your huge archive of DVDs or BluRay discs, or all of your ebooks that you have purchased from Amazon.com. What will happen in 10 years when optical media devices are unheard of, or your Amazon Kindle dies? What will happen to your digital media? If it is restricted with DRM, it will be unusable. This is detrimental to a free society and free culture! Such a situation could be compared with the burning of the Ancient Library of Alexandria!
Speaking of society and culture, aren’t we all taught at a very young age to share with our friends and neighbours? Sharing is one of the fundamental aspects of community! DRM forbids us from sharing our stuff with the people around us. Content providers (who generally have lots and lots of money), are afraid that people will mass distribute their content to lots of people, and they won’t get any of the money. This is an obvious case of you’re doing it wrong. First of all,I think that’s what copyright law is there for. Secondly, by putting DRM on content, it makes it less appealing to potential buyers; who will try to find an alternative, either in the form of a competitor or even piracy. Yes, I believe DRM promotes piracy. If I can buy from you, and get bundled with DRM-ridden stuff, that I can only play on a certain device; or download illegaly the same album or movie or whatever, without DRM, that I can convert into any other format and play on any given computer; only one of these is appealing. Not only does this inconvenience me, and tempt me to break the law, but you don’t benefit at all. At least if people share files illegally, I suppose DRM indirectly (and unintentionally) promotes sharing!
How can we stop DRM? It’s not going to be easy. I think the main way to stop it, is to make a decision not to use it, not to use any content or device which is bundled with DRM. I realise in some rare situations, it might be necessary to buy something with DRM; but just remember that every time you use it, you are promoting it. When we stop using it, and buy from competitors, then eventually the major players will realise that it’s not such a good idea after all. Another way to aid in its decline is to spread awareness, and that is what I’m attempting to do here. Of course, all of the views expressed here are my own opinions.

Today I signed up for that 30 day free trial period that netflix have going on. I was quite excited about it, and it was really one of those moments where I thought ‘I hope this works well, if so, then I’d be happy to pay after the free trial!’ – this isn’t a mindset I’m often in, admittedly.
The signup process was going swimmingly, until it asked for the payment details. I was presented with 2 choices: Credit card or paypal. I chose paypal, since I my credit card will expire soon, and I won’t be renewing it, since the account is in Ireland, and I currently live in Canada. Unfortunately, clicking on the paypal option wasn’t very helpful, since netflix turns out to be one of those silly companies that requires all paypal accounts to be set up with credit cards. This is something that really annoys me, let’s rewind a little to see why more clearly. So, remember I was provided with 2 payment options, credit card or paypal? That seemed reasonable at first glance: not everyone is eligible for a credit card, but you can have a paypal account with just a bank account, eliminating the need for a credit card for online payments (this is the most advantageous reason for providing paypal as a payment option, in my opinion). Requiring paypal accounts to be linked to a credit card, isn’t providing any option at all really, since now you must have a credit card to use netflix.
After a slight hesitation, I caved. I entered the details for the paypal account which is linked to my irish credit card (as opposed to the other one which is linked to my canadian bank account). I figured that even though my canadian bank won’t issue me a credit card, I might be able to find something that will work, if I end up liking the service provided by netflix.
After signing up, I was asked some questions and I ticked some boxes. I assume this was to provide me with more personalised recommendations. After that, I was brought to (what I assume was) the main netflix interface. I spent about a minute or two rating stuff I had already seen, and clicking ‘not interested’ in other stuff that I hope never to subject my senses to.
Eventually I saw something that I wanted to watch, a movie that I hadn’t seen in years, but which recently came up in conversation, and I had planned on watching in the near future. Clicking ‘play’ brought me to a nightmarish screen, one that I had hoped I wouldn’t be seeing. It was a message informing me that netflix requires either Microsoft Windows or Mac OS to play. This was the end of the road for me, so I quickly cancelled my account and moved on in frustration.
A little digging afterwards, told me that the reason netflix doesn’t have a GNU/Linux compatible client, is because of DRM. Of course, if I had known this in advance, I would have steered well clear. Most importantly because I think DRM is just wrong and unnecessary, but also because, as everyone knows, DRM doesn’t work.

When I think of the Earth as a whole, my first thoughts are usually just of a pretty blue and green beachball spinning around up there in space; but for a more comprehensive picture of it, I believe a breakdown of what’s inside is necessary. It’s a one of a kind beachball planet, and it’s the only one we know of that we can live on. The earth is all of the land, all of the water, all of the air, and (most importantly) all of the life inside the spinning sphere. We, as the the most intelligent species living here, have a huge effect on the planet. Of course, the effect we have could be a lot worse, but there is a lot we could do to make our effect severe.
So, on a day where we celebrate our home world, I would like to talk a little about how we can help make it better, with very little effort, by participating in what are known as distributed computing projects. Oh boy, doesn’t that sound scary and difficult! A distributed computing project gives you a piece of software to install on your computer one time, and then tells that to use your computer to help scientists to do their work faster. Once you have the software running on your computer, your job is done, your computers processor does the rest! It will be sent calculations that it will do, and it will return the results to the people who need them (usually scientists/researchers). ‘But don’t those scientists/researchers have access to far better computers than mine?’ I hear you ask (or imagine you ask, at least…). Well, yes; but the whole point of this distributed computing thing, is that dividing the work into smaller parts for less powerful computers to do, is more efficient and faster than leaving it to a handful of ‘supercomputers.’
If you do run a distributed computing project, you will probably notice that your computer might be a little hotter than normal, and your fan is running a lot more frequently, or even constantly. This may worry you at first, as you think your computer is too slow, or that by using the software, you think your computer will become less responsive for your own personal work. This should not pose a problem, as most projects will just use the processor power that is idle, i.e. what you don’t need. If you suddenly need your processor for something, the software will notice this fact instantly, and back off. Usually, most people use only a small amount of their processing power, unless they are playing some high-intensity games or watching HD video or something like that. This is a way to make use of all of the rest of that power while you are getting on with your work.
Choosing a project to participate in
For someone who is new to distributed computing, the first thing you need to know is that there are many different projects to choose from, depending on your own interests. A lot of these projects use the same software on your computer to delegate the work, which can be found here: http://boinc.berkeley.edu/. Once you have downloaded and installed the software on your computer, you need to choose a project (or a few projects), from this list: http://boinc.berkeley.edu/projects.php. Personally, I’m participating in World Community Grid and SETI@home. The former is really a collection of several sub-projects, which you can choose from in their preferences (I choose all), and the latter is a more specific project.
In conclusion, I pose to you this question: can you think of any good reasons not to participate in such efforts? Happy Earth Day, Earthlings!

My brother from a different mother, Kieran Gardiner (you can call him Professor Awesome, now that he’s a teacher!), has gone to South Korea to teach English in an elementary school. He’s blogging about his experiences here. Go check it out. Let’s hope it gets updated more than this blog!
