A sad day for sport

Like many other people all over the world I was shocked to hear that Lance Armstrong is admitting defeat in his battle to prove that he has not breached the rules in relation to the use of drugs in cycling. I am not totally naive and so I would not be shocked to read that someone had definite proof that Lance Armstrong was using drugs. However, one feature of Lance's life to date is that he has been determined to continue battling even when the odds seems to be stacked against him and so it surprising that he is giving up on  this battle.

In his life, Lance has faced a long series of battles:

• He was born to a teenage single-mother. Although he has great praise for the way his mother raised him, it can't have been a very easy life. His mother did have a few boyfriends and subsequently got married, but none of these proved to be a positive father figure for Lance.
• When Lance initially took up cycling it was not a very well known sport in his native Texas and very few people were even aware that the Tour de France was taking place. This also meant that English speakers were not so common on the tour at that time and apparently not particularly welcomed by the representatives of the more established cycling nations.
• Lance was struck with testicular cancer in his mid-20s. Initially the prognosis was not positive and the disease was expected to be fatal. However, he made a recovery and amazed everyone when eventually returned to the sport and performed even better than before.
• As Lance became the most successful competitor ever in the Tour de France it was not surprising that many other competitors regarded him as the one to beat. Lance relished adversity and continued battling when many other people would have retired gracefully and enjoyed the fruits of his success.

Lance has been hounded for many years by allegations of drug use, mainly because people are reluctant to believe that someone could perform so strongly without artificial aids. This is similar to the way the Irish swimmer Michelle Smith de Bruin was treated. The evidence of her drug use was eventually quite strong, but initially the suspicions were only based upon her results. It is becoming ridiculous if athletes can't perform too well for fear of facing accusations.

I think that the time has come to examine the fundamentals of the rules about drug use in sport. In many ways the debate on drug use in sport is similar to the debate on professionalism a few years ago. At that time amateur sportsmen seemed noble, but with the benefit of hindsight it looks like an elitist system that gave an unfair advantage to upper class athletes who could afford to take time off work to train.

I know that the analogy is not perfect, because drug use is dangerous. No athlete will die because he/she gets paid too much, but as we have sadly found out, it is entirely possible for athletes to kill themselves by over indulging in performance enhancing drugs. However, the rules should be adapted to focus on athlete safety rather than on the complete elimination of performance enhancing drugs.

Lance has plenty of experience of dealing with dangerous drugs. As he stated in his excellent autobiography many of the chemotherapy drugs used to fight his testicular cancer were a much more dangerous than EPO (he commented on the fact that the nurses injecting the drugs into his vein wore protective gear to ensure that none of the drugs accidentally spashed onto their skin).

I know it is a radical idea, but we would have a fair playing field if athletes were allowed to use safe doses of certain performance enhancing drugs under carefully controlled conditions.

Is Julian Assange a hero?

In recent times Julian Assange has been making headlines all over the world. Many people (including Julian) would like us to believe that we have a choice between supporting him and all of his actions or supporting the actions of the US secret service and their allies. However, the reality is a little bit more complex than that.

I feel sorry for Julian. But the reason I feel sorry for him is mostly because of his dysfunctional upbringing rather than because he has been unfortunate enough to become a target for reactionary forces within the US military and their allies.

First let me state clearly that I think it is a good thing that the wikileaks site has uncovered many unsavoury actions undertaken by the western powers during their so called war on terror. This is clearly a situation where the response to the alleged threat of terrorism was in many instances much worse than what it was supposed to be preventing.

However, the credit for making this information public must go to Bradley Manning, the brave soldier who made the information public and not to Julian Assange whose only role was to design the process which was supposed to assure Bradley and similar whistle-blowers of anonymity. In fact the process which Julian designed failed  badly in this case and a a result Bradley Manning is currently held in solitary confinement due to the failure to protect his identity and has no prospect of ever addressing the world's media though the window of the Ecuadorian embassy.

Julian is currently facing extradition from UK to Sweden to face charges that have nothing at all to do with his involvement with WikiLeaks. It is true that the laws on sexual assault in Sweden are much more favourable to the victim than in the UK, but this is not necessarily a bad thing. In any case, I am sure that he would get a fair trial in Sweden if he returned there. He claims that he fears that the Swedish government might turn him over to the Americans, but in fact that UK government would be much more likely to do that than the Swedes.

I think that part of Julian's problems are that he has an inflated view of his own importance. The current outpouring of sympathy for his position is only making this situation worse.

Update on SPAM Comments

I notice that the number of SPAM comments being left on my blog has reduced dramatically since I introduced the CAPTCHA test. However, the problem has not gone away completely which tends to confirm my suspicion that the attack is being launched by a semi-automated process. I think that a fully automated process would not be able to breach the CAPTCHA system, but a recent comment (which was automatically detected as SPAM) is a brilliant example of why it must be an automated system:

This blog is wonderful. You are clearly and expert in %PAGE_TITLE%. I have shared this post with all of  my colleagues ...

This could be a boost to my ego because I am proud to boast about my expertise in a wide range of subjects, but %PAGE_TITLE% is not one of the areas that I claim expertise.

Since the CAPTCHA is not being totally effective in blocking the SPAM, I will disable it. Instead I will force users to register for an account in order to leave a comment. In addition I have enabled a rule whereby comments have to be approved before becoming visible on old posts (most genuine comments are left fairly soon after the post is initially published).

Improving the accuracy of the GPS in Your phone

The GPS device in your phone is normally very accurate. However. like all computer devices when it messes up it can often do so in a spectacular way (e.g., I once went running around Galway at a moderate pace and then found out that my phone thought I had been swimming around the Irish Sea at a world record speed)

The Global Positioning System (GPS) is an amazingly complex piece of technology, so I suppose it should not be surprising that it occasionally fails. However, there are a few things that you can do to to increase the accuracy of your GPS readings:

1. The software that interprets the GPS and other signals required to determine your location is very complex. The technology involved is constantly being updated. Therefore, if you are experiencing poor performance it is a good idea to update the operating system software and/or buy a new phone.
2. The preferences on your phone should include "Use Wireless Networks" and "Use Sensor Aiding" - you should be sure to enable both of these options. On Android devices this will be under the "Settings\Location and Security" menu item, I am not sure where the equivalent setting is on an iPhone, but I assume it is named something similar. If you enable these it means that your phone can use several other clues to help decide where it is located even if there are not enough GPS satellites clearly visible in the sky.
3. Don't start running until you have a good GPS signal. It might take a minute or two for your phone to lock onto the GPS satellites properly, if you are moving around while this process is happening you make it more difficult for the phone to guess its position. The RunKeeper app even has a useful feature whereby it will warn you if you try to start tracking a run without having already locked onto the GPS system. If your favourite app doesn't have this feature then it is probably worth installing a specialised application such as GPS status to check.
4. Change your privacy settings to allow Google/Apple collect data from your phone. This is a clear case where you need to trade off privacy versus a benefit for yourself. The way that the "Use Wireless Networks" feature works is that hopefully Google or Apple has a record of the locations of the WiFi points that are currently visible to your phone and since the range of a WiFi network is not very large, it can quickly narrow down the possible locations where you might be. However, if nobody has shared this information for the area where you are running, the feature won't work. I personally don't think this information is very private because anyone walking past your front door can collect the same information, but I know many people feel differently. In any case, it is in your own interests to help map the location of  WiFi points in your neighbourhood especially if you are going to be regularly exercising in the same place. If you are really worried about privacy, then enable it for a few runs along your normal route before turning it off again.

I hope this information helps. If not, remember Google is your friend and a quick search of some of the forums related to your brand of phone will probably provide you with plenty of other useful tips.

Incidentally, I previously posted that I was switching back to using MyTracks instead of RunKeeper. However, I sometimes find that it is interesting to have both applications tracking my progress. Both applications have a tendency to occasionally crash for no reason, so having both applications recording your activity means you are fairly certain that you won't loose any data.

At the moment I have RunKeeper configured to announce periodic summary statistics in a female voice while MyTracks uses a male voice. The way I have them configured the two application normally announce at different times and because of the voice difference I know instantly which application I am hearing statistics from. Occasionally the two applications decide to announce statistics at exactly the same time which ends up sounding hilariously like a married couple arguing about whether or not the speed limit is being breached.

Update: 21-Aug
In the tips above I forgot to mention the obvious tip - try rebooting your phone. I sometimes find that my phone won't lock onto a GPS signal even if I can see the screen clearly and everything seems to be set up correctly. In these cases, turning the phone off and then back on again will often solve the problem.

Hacking becomes mainstream in IBM

In a large company like IBM, not many employees have a chance to meet and interact directly with the CEO. However, the CEO will act as a role model for all employees about how the should behave and all executive communications are regularly examined carefully for clues to what is considered good behaviors.

In the book "Who says Elephants Can't Dance", Lou Gerstner described about how he was advised to start using email when he took over at IBM because apparently his predecessors got secretaries to read email on their behalf and this did not project a very good image for a leader of a high tech company. In the early 1990s reading email was considered to be leading edge. When Lou was replaced by Sam Palmisano in 2000 nobody questioned whether or not he was using email, because by then it was assumed that everyone would be. However, when Sam was recently replaced by Ginni Rometty the pendulum had swung so far that people have now started boasting about how little email they need to use.

Ginni doesn't look like a typical Hacker,
but appearances can decieve

In the short time that she has been in charge, Ginni has proven her tech credentials by becoming a highly visible user of social media communication tools. All of he quarterly employee messages are delivered on an IBM internal blog and she also regularly uses many of the tools provided by the IBM Connections product.

In a recent update posted to her blog she even went a step further and announced that she was going to hold a "Social Business Hackday" in which she expected participation from all of IBM's 400k+ employees. The exact format of this Hackday is still being decided, but what is clear now is that during a designated day in early September all employees will be expected to come up with a plan for how they can make better use of social media tools in their work. In addition it is expected that they will make concrete steps to implement this plan during the Hackay.

I think this is very significant for a number of reasons:

1. The original Hackday events in IBM were launched without any formal management approval. I think the originators were afraid to ask for approval in case it might be refused. Over the years the reaction to any executive who found out about the events has been mostly positive. However, we have has some feedback that the word Hackday projects a negative image. I think that when the CEO publicly declares her support for the events we should not have any trouble convincing other IBM managers that they are a good idea.
2. In IBM we have always been careful to ensure that participation in Hackdays was as diverse as possible and not restricted to just developers. For example we had prizes for the best hacked business plan and we also even had a semi serious prize for the best hack that didn't involve either Sametime or Connections (because these products are extremely popular subjects for Hackday projects). I think that the Social Business Hackday will increase the participation level even further.

Officially this will be an IBM internal event so I am not sure how/if it will be publicised outside of IBM. However, due to the nature of the event I am not sure that it makes sense to keep it secret (even if we could).

My planned mid-life crisis

I will have a significant birthday this year (I won't say what age I am, but I am approaching the half way mark in my bid to persuade the President to send me a congratulatory cheque). It is traditional for people of my age group to have a mid-life crisis where they try to make themselves feel younger by doing something normally associated with younger people.

I considered buying a flashy sports car, but I didn't think that would suit my personality. I also considered going out to late-night parties, but since I used to fall asleep at parties even when I was younger I ruled out that possibility. Eventually I decided that the right think for me to do was to participate in a Triathlon in Loughrea on 9th of September. I am reasonably confident that I can competea 5km run and a 20km cycle should not be a major challenge, but the 750m swim will be a major challenge for me.

I did a few practice swims in the gym before deciding to sign up and since they went fairly well , I am now purchasing the necessary gear for the event.

The fact that my nephew is also planning to take part should be a major help to my preparations. I don't know if we will be able to emulate the teamwork shown by "Mrs Brownlee's Boys" but hopefully we can complete it without any disaster.

Recognising SPAM comments on blogs

Like anyone who has been using the Internet I have often received SPAM emails, but it was only recently I encountered SPAM comments on my blog. The content of SPAM comments on blogs is very different from the content of SPAM emails and so I didn't instantly recognise what was happening - luckily Google has more experience of such practices and they immediately removed the SPAM comments before I even got to look at it.

SPAM emails typically try to trick the receiver to part with some money and/or click on a link which will infect your computer with some malware. The content is not always offensive, but it is certainly embarrassing to read about some of the alleged services being offered. Very few people who read a SPAM email would confuse it with a genuine email, but of course if the spammers send out enough emails they will surely find someone foolish enough to be tricked.

When I first established this blog, I was given the choice of implementing a policy that all comments would have to be approved by me before becoming visible on the site. I decided not to implement this policy because I was not too worried about the type of comments that user would leave. Until recently, my confidence in human nature was repaid and none of the hundreds of comments left over the last few years were comments that I would not have approved if I was reviewing them.


Since the same word is used for SPAM emails and SPAM comments, I foolishly thought that the content would be similar. However I recently discovered that the content of SPAM comments is surprisingly different from email SPAM, because all the authors are trying to do is manipulate their Google page rank by posting a link to their site on your blog. As a result the SPAM comment will deliberately be crafted to look at first glance as close as possible to a real comment.

My knowledge of the topic this changed about a 2 weeks ago ago when I received notification about a few surprisingly complimentary comments left on my blog. These comments were praising the quality of my writing and although I was surprised at how gushing the praise was, I didn't initially suspect that anything untoward was happening (bloggers typically have an inflated self-image and so I suppose it is not surprising that blog authors will often accept such praise at face value). However, when the trickle of such comments grew larger my suspicions arose and I began to look a little closer.

None of the comments were duplicates of each other, but they all followed a pattern. The comments were gushing in praise about the quality of the blog, but they would refrain from specifying what exactly made the content interesting (presumably because the comments were being left by some semi-automated process that doesn't involve actually reading the content). The comments would all end up with a line like "you might also be interested to read my blog" and then they would provide a link to their own site (but of course genuine comments also frequently end with a line like that).

When this flood of comments started, I was on vacation without convenient access to the internet. Therefore, about a week had passed before I investigated and about 40 of these comments had been left. Luckily the Google Blogger platform was intelligent enough to catch all but 2 of these as SPAM without me having to do anything. When I then reviewed all the comments from the previous year and I found only one which was a previous incidence of the same pattern (my naive self was pleasantly suprised at the praise, but my new Jaundiced eye brought me down to earth). So clearly my blog has been added to some list of "easy targets" for comment SPAM.

A sample CAPTHA

In the meantime, the flow of SPAM comments continues to grow even more frequent. Although it is good that the blogger platform automatically categorises them as SPAM and hides them, it is still a nuisance that I can do without. Therefore I have been forced to implement a captcha system to slow the flood.

I personally hate captchas because I find them very difficult to complete (perhaps it is my fading eyesight). However, I think that I will need to leave this defence mechanism in place for a while until the spammers go away to softer targets.

Irish Revenue Online Service is an example of the wrong way to implement an online service

Most citizen's don't particularly enjoy paying taxes, because nobody  like parting with their hard earned money. Therefore, the tax authorities should try to make the process of filing a tax return as painless as possible. In fairness the Irish tax authorities have done a good job  of making the paper forms and associated documentation quite easy for the lay person to understand, so when I recently started using  the revenue on-line service  I was expecting that it would be equally simple to use. Unfortunately I was very disappointed and found it very frustrating.


This service was originally developed to be used by tax professionals who spend most of their working life dealing with tax issues and is it is optimised for this type of user. It was only in recent years that they opened the system to "normal taxpayers" and they have been surprised that the system has not proved more popular. However, from my experience (which I will describe below) I can totally understand why people are sticking with the much more user friendly paper based system. I understand why the tax authorities would prefer people to use the on-line system, but they will have to adapt the system significantly if they hope that a large section of the population will be willing  to switch.

The first hurdle that users must battle with is the registration process. They need to be careful to avoid fraudulent registrations, but the system they devised is almost guaranteed to take about over a week to complete and hence relatively few normal taxpayers will have enough patience to do it properly.

1. When you initially register on their web site you will in a normal enough looking web site registration form. However, when you complete this form you are not really registered you have simply applied for a ROS Access Number (RAN) which is required to progress to the next stage. For security reasons this RAN is printed on a physical piece of paper and then posted to your home address. This is done to ensure that the person applying for access to your tax records is really you (or at least has access to post delivered to your home).
2. However, the need to print and post the document ensures that there is a delay of several days before you can move to the next steps which is to apply for your Digital Certificate. When you apply for the certificate, they don't issue it to you straight away, but instead they generate an access password which must be printed out and posted to you. This second postal interaction doesn't really increase security, because anyone who can intercept the first letter will probably be equally able to intercept the second. 
3. In any case, you must wait until your password arrives in the post before you can retrieve your Digital Certificate and begin using the system.

Although this system seems quite straight forward, the delay involved effectively stopped me from using the system the first two years I tried. Like many citizens, I normally only need to interact with the tax system once per year when filing a tax return. As soon as I have collected all of the necessary information to complete a return, I like to complete the return straight away so that I can then relax and forget about the tax system for the next year.

The first year I decided to try filing my tax return on-line I was full of enthusiasm. When I had all of my documents ready to file a tax return, I was disappointed, but not surprised that I had to wait for the first postal step. However, when the letter arrived with the revenue access number I was frustrated that I could not complete the form straight away and so I completed the return on paper before the second letter arrived.

The next time I thought about the ROS system was when it was time to file a return for the following year. I found the old letter in my file with the access code to retrieve my certificate. Unfortunately when I tried using it I was told that the password had expired. Therefore I went back to using the paper system for another year.

The third year I decided that I should be a little more patient and so I completed the registration system from scratch. This time I encountered technical issues when I went to retrieve my password. The system gave me the unhelpful message "Something has gone wrong. Please contact the ROS HelpDesk". In fairness, the people operating the help desk were very responsive and did their best to help. However, it was hard for them to diagnose the cause of the problem from this generic message.

1. Their first suggestion was that the browser I was using might not be a supported one. They supplied me with a list of supported browser versions. I tried three of the browsers on their list but all of them gave me the exact same error message.
2. The next guess from the help desk people was that it might be an issue caused by the operating system I was using. They suggested that I try again on a Windows system. Since I would never destroy a good PC, by installing Windows on it, I was forced to create a Windows virtual machine image that I could use exclusively for accessing the ROS system,
3. Unfortunately when I tried accessing the system from the windows system it was still telling me "something has gone wrong". When I told this to the help desk, their next suggestion was to try updating the version of Java installed on the machine. Luckily this suggestion worked and after a delay of 3 weeks I was finally able to use the ROS system.

Since I am using a virtual machine to access the tax system, I should be able to keep a backup of my exact environment and use this to access the site next year. However, many users will be constantly updating their environment and it is likely that they will encounter fresh issues each year.


I think that there are a few simple changes that could be implemented to make the ROS system easier to use for non-professionals:

• If they abandoned the use of private digital certificates it would simplify the registration process and also allow them to be much more fussy about the details of the software used to access them. Most banks think that normal SSL encryption is secure enough for their web interfaces, so surely the revenue site should go along with this concensus.
• It would be helpful if the web site gave more helpful error messages. As a software developer I appreciate that it can be difficult to generate meaningful error messages, but surely they could do better than the simple "something has gone wrong". 
• It would also make life easier if they added an option to summarise the user's environment and email it to the help desk people so that they could see all of the relevant details at one glance. The  help desk people were simply guessing in the dark about what might be the cause of my problem, because there was no better way for them to diagnose the problem.

In summary the process the system seems to be quite fussy about the computer environment users have when trying to access the site. Tax professionals who spend quite a bit of time accessing the ROS site will probably be willing to install specific versions of software to enable them to access the site. However, the majority of citizens who only want to access the site once per year will be much less willing and hence will probably stick with the paper system unless it is made easier.

RunKeeper compared to MyTracks

I am both a fan of exercise and of technology. Therefore, whenever I run or cycle, I like to use an application that leverages the GPS functionality of my phone to keep a track of exactly where I have been going and how fast I have been running/cycling etc. I have been a long time happy user of the  MyTracks  application from Google. Recently I converted to using RunKeeper because after watching a presentation on the benefits of sociability in training apps, I wanted to use an app which was more sociable. Ironically I am now switching back again because RunKeeper is too social.


In terms of core functionality, the tow applications are similar. MyTracks  application is a typical Google product which tends to appeal to most geeks like myself. It doesn't have lots of features, but it does one thing and it does it very well. The one thing it does is use the sensors in the phone to track exactly where you went.

• It does not even assume that you are using it for tracking fitness related activities - for example I first started using MyTracks, I was walking around neighbourhoods and tracking the location of roads so that I could update OpenStreetMap.
• If you are using MyTracks for tracking your training you can simply select the menu item "send to Google" each time you complete an activity and Google will automatically create a Google Docs spreadsheet with all the details of your training statistics without any effort on your behalf.
• The level of detail in the data is more than would be collected by a professional athlete, but there are no fancy graphs or charts. However, it is easy to use that application of your choice to create any chart you want.
• Likewise they don't attempt to implement any sociability features, but they make it easy to export your data to any other application if this is what you want to do. For example, I occasionally  use the excellent Tracks2Miles application written by Ben Hardill to send my training data to the DailyMile site so that I can share information with friends.

I said that MyTracks makes no direct attempt at being sociable with your training data, but the  makers of RunKeeper seem to assume that the only reason you are collecting data is so that you can share it on their site. If these applications were real people, I would compare MyTracks with a work colleague who believes that there is no need for social chit chat at work. In contrast RunKeeper is more like one of those annoying cheerleader types who keeps offering encouragement (whether you want it or not). Initially this encouragement is great, but after a while it begins to get on my nerves.

• The only place that the RunKeeper application will store data is on their site. Of course it is possible to later export the data to share it elsewhere, but not many people will go to this trouble. I suppose this is a natural choice for them, but I personally prefer the Google approach of making it easy to share data directly from their application to wherever you want.
• The charts on the RunKeeper site are much more visually appealing than the plan text spreadsheet created by MyTracks, but Google actually makes the raw data easier to get at.
• The default settings on RunKeeper is to share every piece of data with everyone. Of course it is possible to change these settings, but it would be easy for a shy person to be embarrassed by accidentally over sharing.
• The RunKeeper site will constantly send you congratulatory emails and/or post to your Facebook profile when you achieve significant training milestones. I suppose this is probably viewed as a good feature by some people, but personally I found it to be patronizing when I first started using RunKeeper and went on a fairly short slow run to try it out. They were gushing about how it was my longest run ever and a personal best (of course it was my longest ever run from their point of view).

Choosing an application, is somewhat like picking whom to be friendly with - there is no one choice which is right for everyone. Both of these applications are very good, but I think it is important to pick an application that its a good match for your personality. This is why I am sticking with MyTracks (for now).

Why I deserve to be the person getting the free eCar

ESB recently announced that they plan to give away some electric powered cars (eCars) to private individuals in return for some help in publicising the benefits of this new environmentally friendly mode of transport. The application form ask you to state why you believe that you would be the ideal person to receive an eCar, but they only give you a small text box in which to write your reasons. Therefore I decided that I would write this blog post stating my case at length.

1. I am a blogger and would use my blog to help publicise my experiences with the eCar in addition to cooperating with any PR activities arranges by ESB themselves.
2. I have a record  of writing about electrical sustainability issues on my blog and in particular my work with local schools to do Young Scientist projects relating to Smarter Power.
3. My current car is a hybrid car. I chose this because I am interested in helping the environment and because there were no pure electric cars available on the Irish market at the time,
4. My commute to work is only 8km so I would not be a demanding user of eCar, but there is already an eCar charging point at my place of work and I frequently travel long distances at weekends and I would be happy to see how an eCar performs on these journeys.
5. Since I currently  own a hybrid car, all the cars in our household would be electric powered in some form is I was lucky enough to be chosen as a recipient of a free eCar.

I hope you will wish me luck in the application process.
