• Updating the SDK: If you run the SDK as the normal user, the “Help > Start Updater” menu option still exists and appears to work. It seemed to detect that I had sudo access and asked for my password but then hung using 100% CPU. Instead of using that menu option, I ran /opt/QtSDK/SDKMaintenanceTool as root which works.
• Running the QEMU phone emulator: This failed with “Qemu finished with error: Exit code was 1″. To fix this, I ran QEMU manually:
  /opt/QtSDK/Madde/bin/mad remote -r dfl61-harmattan_2.2011.39-5 poweron -fg
  This showed I needed write access to the qemu disk images. As I’m the only user on the system*, I gave all users access:
  chmod a+w /opt/QtSDK/Madde/runtimes/dfl61-harmattan_2.2011.39-5/arm-qemu-rm680-*

Hope this helps someone stumbling across this via Google

* = Yeah. There was no need to install Qt into /opt – it just seemed tidier than putting it in my home directory

I’m not the only one having issues with similar webcams:

• https://bbs.archlinux.org/viewtopic.php?id=121607&p=3

Based on the patch in the third link in that list (for a few different webcams), I’ve found that the following trivial patch fixed the problem:

If you want to try that before Fedora make a fix available, it’s easy enough to build your own kernel

The other day, my daughter (too young to understand a numeric countdown at the moment) was messing around at dinner (not unusual). I wanted a simple graphical way to explain that after a set amount of time I would take her dinner away to encourage her to eat up.

Slightly to my surprise I couldn’t find anything with Google (my Google-fu is obviously weak). So I extended my little timer so that it shows a green ball for each second remaining. As the time ticks down, the balls turn red.

I was originally going to use a progress bar but this way shows, at a glance, how much total time there was…

I think it’s working pretty well

I drew a beautiful masterpiece that sums up the situation to post to the b3ta AV image challenge but as a new member it turns out I’m not eligible to post until Tuesday.

Oh well, it reduces the number of people who will doubt my mental age to the readership of this blog entry…

Four mackerel I caught this evening spinning in the Solent

The event was not at all what I expected; it was well attended but the average age was higher than I envisaged. Approaching my mid-thirties, my young daughter often makes me feel old – today however I felt young! Also the format was not what I imagined. Instead of a mini version of the national conference with impassioned debate and voting on controversial motions it was a cosy chat with councillors discussing their plans and general agreement (mostly via post-it note) on motions to be voted on at the national conference.

There were issues raised that tempted me to talk – in particular the cost of housing in Winchester but, at least on this occasion, I kept quiet. Firstly because I wasn’t keen for most of the membership’s first sight of me to be disagreement in a very consensual atmosphere. I would very much have liked Barton Farm to have been built on but the Liberal Democrat council opposed it. Given I own a flat about 500m from the proposed site, my support might be slightly unexpected but I am (by most standards) fairly well paid and struggled to buy a house in Winchester – most people are less fortunate!

I was slightly sad that a motion at the national conference in support of equal marriage rights was not discussed. It seems self-evident to me that the discrimination in our current laws should be changed but maybe it was not discussed because it would have been unanimously supported.

This was all new territory for me and I hope to attend more party meetings in the future (Em’s shift patterns allowing) so hopefully I’ll feel like one of the natives soon – it wasn’t what I expected but everyone was very welcoming.

So from being a fish out of water to hauling fish out of water… After the politics I went fishing. We hadn’t arranged it in advance but I met my Dad at the coast. It was a warm summer’s evening perfect for mackerel and there were shoals of them teeming along the shore. We could have caught as many as we liked. I stopped at four, plenty for my (small) family – Dad (unusually) chose to go up to double figures as he wanted some for neighbours. It’s not always as easy as this evening but the fish combined with the weather and the views made everything seem perfect. I’m even starting to feel like I know what I’m doing – at least with a mackerel rod!

mount.nfs: Remote I/O error

In order to be able to mount the NFS shares I had to add -o vers=3 to my mount command.

I understand that with the state of the economy, the deficit, Afghanistan the Digital Economy Bill might not be the top priority in this election. Apparently however, it’s important enough to railroad into the statue book with controversial amendments being added days before becoming law. Watching the passage of the bill was an eye-opening experience….

Everyone should watch a parliamentary debate on something they know about, finance, shipbuilding whatever. See how gvt “works”. #debill

This law was not made the way I expected law to be passed. What I expected was neatly summed up by Cameron Neylon:

Representative democracy bases its existence on the assumption that the full community can not be effectively involved in an informed and considered criticism of proposed bills and that it is therefore of value to both place some buffer between raw, and probably ill informed public opinion, and actual decision making. This presumes that MPs, particularly party spokespersons take the time to become expert on the matter of bills they represent.

Instead what I witnessed in debates in the House of Commons was a scarily ill-informed, rushed mess which was typified when it emerged that the “Minister for Digital Britain”, who is in charge of this travesty thought that the IP in “IP address” stands for Intellectual Property

There were MPs who “got it” from all parties, exemplified by the Labour back-bencher Tom Watson but only the Lib Dems voted against the bill as a party and even then, many did not turn up to vote!

I am not angry because I file-share illegal files. I do not. Copyright violation is already an offence. As that well-known bastion of communist hippies, the Telegraph, says:

In the past the lawyers had to go after the infringers, with actual proof. Remember being innocent until proven guilty? That’s out now. Now, the holder of the internet account (Mum, Dad, Granny and the small business that can’t afford the legal fees) will be held to account for what happens over their connection.

Aside from the eye-watering insight into how law is made, I’m cross for a number of reasons:

• It won’t do what it tries to do, The Telegraph again:

  ” In April last year, Sweden’s internet traffic took a dramatic 30 per cent dip as the country’s new anti-file sharing law came into effect. Before this, Sweden, the home of the Pirate Bay, had been a hotbed of illegal trade in movies and music.

  But several months later traffic levels started to surpass the old levels. Consultancy firm Mediavision found that the accessing of illegally shared movies, TV shows and music simply recovered. But there was one crucial difference. Much of the internet traffic was now encrypted.”

• It will make running a wifi hotspot a massive headache Small cafes have to decide whether to try to be ISPs or be responsible for copyright infringement on their hotspots and use technological measures to prevent abuse. Good luck finding workable “technological measures” that don’t massively restrict legal use of the internet!
• It will have a chilling effect on free speech The Bill has a clause that will allow “the secretary of state for business to order the blocking of “a location on the internet which the court is satisfied has been, is being or is likely to be used for or in connection with an activity that infringes copyright” (via The Guardian). It has some safe-guards but there is concern that sites like WikiLeaks (which recently broadcast leaked video footage of American Pilots firing on innocent people including Reuters journalists) could be banned. ISPs will be worried about court costs which means even the threat of a ban will often get pages removed.

So if you’ve made it through this far, I’m hoping you agree with some of what I’m saying. So what can we do? A number of things:

1. Join the Open Rights Group who campaigned against this fiasco.
2. Find out about your local candidates. For example, which way did they vote on the Digital Economy Bill or did they not even bother to show up for work?
3. Share info about the candidates with other people who care about internet freedom.
4. What else? I’m not sure – I’m half tempted to wander down my local high street (Winchester) handing out leaflets summarising this blog entry and pointing out what one of the local candidates (Martin Tod) is a founder member of ORG.

If you have better ideas, let me know in the comments….

Update: We won 4-1! I was there when the Saints went marching in! Great atmosphere. Loved it!

Katie can now happily play in the sunshine in the garden.
