Colin's Journal: A place for thoughts about politics, software, and daily life.
Many of the EU15 member states are struggling to come to terms with the possible accession of Turkey. Even supporters of Turkish membership, such as France, seem intent on making it difficult.
The European Commission’s new stance that negotiations with candidate countries will be suspended if those countries fail to meet membership criteria is to be welcomed. The 100% success rate of countries negotiating membership during the recent expansion could easily be interpreted as meaning that there is little chance of rejection. By explaining the consequences of failing to meet membership criteria the commission increases the impetus for countries to reform. Hopefully this new approach will be applied as equally to Turkey as it is to Romania, Bulgaria and Croatia.
The new enlargement commissioner, Olli Rehn, is reported as wanting to introduce a permanent mechanism to limit the free flow of workers from Turkey to other EU states. This is a badly thought out proposal that has been rightly shot down by Turkey. A permanent mechanism to limit movement between Turkey and the rest of the EU would distort the single market and devalue membership of the EU significantly.
Being an EU citizen grants you the right to move freely between member states. If countries gained the right to limit immigration from other member states it would damage the single market. Currently British citizens can be sure that their rights will be respected when buying a house or starting a business in France. If member states can arbitrarily restrict immigration then that certainty is removed, and people are far less likely to make investments abroad.

Some of yesterday had to be spent doing website and system maintenance. The first change to my website is that double spaces after a full-stop are now preserved using non-breaking space characters. Currently this only applies to those pages that I created in a text editor, but I hope to implement this for OpenOffice pages in the future.
A small number of people have recently started using my images in their websites and using my webserver to serve them. While I can’t do much to stop people copying the images, I can at least use Apache’s mod-rewrite to block my webserver from being used to host them. There are two downsides to this: direct links to my images from other sites will no longer work, and image search sites such as Yahoo and Google will not display my images correctly in their search results page. To link to one of my images from a website the link must now go to the HTML page that contains the image rather than the image directly.
On my home computer I’ve added a white-list of users that are allowed to SSH in. This means that I can give guests weak, easy to remember, passwords on my computer without it being vulnerable to a dictionary attack on the network. For the technically curious this was done by using the PAM listfile module in /etc/pam.d/sshd.
The BBC is usually reasonably accurate when it comes to reporting on immigration issues in the UK. Their current piece on “Beating the sham wedding cheats” however starts with a significant inaccuracy:
The number of bogus weddings has increased dramatically in recent years according to Home Office records.
The scam exploits a legal loophole meaning that foreigners can stay in the UK if they marry an EU citizen working in the country.
My understanding of a legal loophole is that the effect of the law concerned is unintentional. The freedom to bring your spouse into the EU country where you work is a fundamental one agreed at the EU level, not something accidentally granted through legislative incompetence.
Sham marriages are a problem whether the participant is a UK national or from another EU country. Restricting the ability of EU nationals to bring their families into the country would hurt a significant number of people, and make little dent in the problem.
I wonder whether the BBC piece is even original work, rather than being taken off a wire, as almost identical wording can be found in the corresponding Guardian article.

I’ve taken pictures of musicians before, and I’m slowly getting better at it. I had previously met some of the people involved, and so I was comfortable with taking their pictures. Even with a 70-200mm lens I need to be close to my subject, and so it is important that we are comfortable with each other.
I only arrived at the fair towards the end of the day, and during the final act the light failed completely. As a result, I don’t have a good sampling of the whole festival, but I did take enough pictures to justify putting together a public album “Harbord Village Fall Fair”.
The photograph here was taken at the Halifax busker festival.
The 1.0 Preview Release of Firefox is now available. I recommend that anyone using Internet Explorer download Firefox and give it a try. You can use IE and Firefox side by side, and easily remove Firefox if you don’t like it.
Only when I use IE at work do I notice the significant improvements to web browsing that Firefox includes. The first thing I miss is tabbed browsing (the ability to have multiple pages displayed in tabs in one window), something I use all the time in Firefox. The lack of pop-up blocking in IE is another major pain.
Another Firefox convenience is the dedicated web search box. This allows in-browser searching across a variety of sites. I find myself using the Google, Amazon and Dictionary.com searches the most, but keep a few others in the drop-down selection.
Type ahead find is a great way to navigate online manuals – press the single-quote key (‘) and type in the name of the link that you are looking for. Similarly finding non-link text is as easy as tapping forward-slash (/) followed by the text you are looking for.
Live Bookmarks provide RSS aggregation in the browser, which is a great idea. Unfortunately Firefox doesn’t yet flag new links, so you have to remember which was the last article that you read in a particular feed (something I’ve filed a enhancement bug
The check that Firefox performs to look for new releases is less useful on Linux (where most distributions already do this for all applications), but should be very useful for Windows users. As well as delivering timely security patches this should also encourage rapid rollout of new features. This significantly increases the odds of an improved HTML being available to web developers sooner rather than later.

Most towns that have an ocean, sea, lake or river in the vicinity provide some means for a tourist to float on water. Row boats are a lot of fun, while tour boats and ferries are restrictive but can give you a different perspective on a place.
In Halifax there are a plethora of different boating opportunities ranging from deep sea fishing to the humble Dartmouth ferry. The tour that we went on, arranged by the conference that Shana was attending, was a simple trip around the harbour.
Sunsets seen from water are often more interesting than when seen on land, and on our trip we where rewarded with an interesting sky. The container port’s large cranes added an industrial silhouette, which unfortunately loses something in the small format that I have to use on the web.
Recently I’ve not given myself enough time for journal updates, managing at best only weekly posts. I hope that this will change shortly, but sometimes, like now, I can think of nothing interesting to say that the world doesn’t already know. In lieu of real news, insight or opinion this post will consist of nothing more than odds and ends.
Over the long weekend the annual air show was held here in Toronto. Usually we get a reasonable view of the show from our deck, but the visibility was pretty poor this year until the end of the final show on Monday. When the Snowbirds had finished their various tricks they flew right past our deck, allowing me to take one of the best pictures of that afternoon.
Over the last week I’ve been hacking together a small image database application to capture information about scans of images. The requirements are specialised enough that using an existing image database wouldn’t work too well, so I’m putting something together using SQLObject, MySQL (yuck), ModPython, and SimpleTAL.
SQLObject is working out very well, and SimpleTAL is at this point pretty much bug free. ModPython on the other hand is a great idea, but is currently full of bugs. Defects found so far include: Old versions of modules being used (despite the PythonAutoReload directive), name-space problems when two modules with the same name are in different directories, and the Session implementation always timing out (use session.__accessed = time.time() after session.load() as a work around).
While ModPython will suffice for my uses I would avoid it for critical development at this point (version 3.1.3).
This post is about computers, so if that bores you click on the pretty picture instead of reading on!
When adding new hardware to a machine running Linux it will either work straight away, or it will be a challenge to your patience. For example if you add a new Ethernet card to your machine there’s a very good chance that on rebooting it will be found and will work with no extra software being required.
When hardware isn’t fully supported however things become complex and trying. Take for example the Epson Perfection 2480 scanner that we purchased yesterday. I had already researched Linux support, and found that neither the official Epson software for Linux (iScan), nor SANE support it. Just this week, however, on the development mailing list for SANE there was a thread about this scanner, and a couple of patches that enabled support for it.
To get the Epson Perfection 2480 scanner working I had to:
After all this the scanner now works.
The downside to taking lots of photographs is having to trawl through them afterwards to find the good ones. Doing this is a mixed blessing. On the one hand finding an good, and more rarely a captivating photo, is a great reward. On the other hand looking at so many photos that just don’t work is frustrating. On seeing a photo I have questions running through my mind: what was I trying to capture? Why did I expose it like that? Why couldn’t I get rid of that extraneous object from the frame?
Until I’ve worked my way through the Halifax, Peggy’s Cove, and Lunnenburg photos I will not have anything to illustrate the next stage of our holiday. Once I have been through the remaining photos I should be able to write some more about our brief trip around central Nova Scotia. I may, time and motivation permitting, even get around to creating a proper album for the trip.

Over the last two weeks I’ve been travelling around central Nova Scotia. The last post I made described Halifax, and the only two days of poor weather that we encountered on this trip. On leaving Halifax we drove west along the coast en-route to Lunenburg.
The coastal road quickly led away from the heavily forested Halifax area into exposed moorland. Trees become rarer, interspersed by large areas of grass, shallow lakes and glacial boulders. It is a magical environment to drive through as the road weaves between lakes and boulders grace the horizon in all directions. I would need at least three photos to capture the feel of the place, but the first one in this post gives some idea of what it is like.
Although Peggy’s Cove is a heavily visited destination I’m very glad that we joined the crowds. The main attraction is meant to be the lighthouse, but I didn’t find that particular inspiring. We parked in the tourist information car park on the edge of the hamlet, rather than at the lighthouse. This was a good choice on our part as it allowed us to wander through the almost deserted marshy ferns and grasses towards the ocean.
Despite it being a very pleasant day the wind coming in at Peggy’s Cove was fairly strong. Medium sized waves crashed enthusiastically against the shoreline sending spray many meters into the air. It was easy to gain a respect for the power of the waves coming in, especially on such a relatively calm day.
Only after seeing the rough seas crashing against an unforgiving coastline could I appreciate the small harbour at Peggy’s Cove. The harbour is naturally sheltered in an amazing contrast to the area immediately surrounding it. The water is as calm as a small lake, with a handful of dinghy’s moored alongside the odd fishing vessel.
After Peggy’s Cover we continued on the coastal road all the way to Lunenburg, passing through numerous small towns and villages on the way. Although many were photogenic places we didn’t have time to stop and wander around, and so could only admire them in passing.
My apologies to those reading this over a dialup link – I’ve tried to keep the in-line pictures small, but this post is still going to take a while to load.
