Getting Started with OSGi: Dependencies between Bundles

It turned out that his friend had dropped his brand new boller hat into the fountain. Unfortunately the fishing approach didn’t work so there was only one thing for it:

He did get his hat back though!

Southampton’s council elections work by electing one third of the 48 councillors at each election so to get a view of the makeup of the council you have to look at three election results and to see which seats were up for grabs this time you have to go back to the 2007 election. Therefore I’ve collated all that information in the table below, I’ve highlighted the seats that changed hands this election:

Note that in Millbrook in 2007 and Harefield 2008 two seats were up for grabs although neither for the full 4 year term so 1 of each of them got replaced in the future elections. This means the council now has 26 Conservative members, 19 Labour and 3 Lib Dems.

I found it interesting how the Tories actually gained seats from the Lib Dems as well as losing others to Labour.

I’d been looking around various garden centres for an arch trellis but they all seemed to be quite big and suitable for sitting on top of fence panels. As I just wanted something over the doorway they would of looked far to bulky so I decided to make my own.

Having bent the bamboo in the same way I did for my mini-polytunnel I then screwed two planks of treated wood into the wall, one on each side of the doorway. I then just hammered staples around the bamboo to hold it between them. Now I just need to wait for the rose to grow a little more!

Figure 1: Bamboo bent and tied into loops

The nice thing about growing your own bamboo is that you can shape it whist it is still green and malleable. Unlike other home made polytunnels that bend two shop brought canes together with hose pipe to connect them into a loopI bent my cane as soon as I harvested it, tied it up and left it out in the sun to dry for a few weeks (see figure 1). This meant that I had a single smooth loop to work with.

I selected two loops of a similar size and used 4 straight canes to make a rectangular base. I then tied the two loops to each end of the base using garden twine.

The next step was putting some polythene sheet that I got from a local garden centre over the top. I fixed it by wrapping it under the base and around the supports and tieing it on using some galvanised steel wire that I had left over from making raspberry supports (see figure 2). I wanted the tunnel to last a couple of seasons so I was worried the polythene would tear where the wire went through so on most of the ties I first stuck down some parcel tape to hopefully stop the tearing. Not sure how necessary this was and it does make it look a little messy so I’m not sure I’d do this again.

Reading around there are two concerns about polytunnels, the first is wind knocking it over and the second is ventilation. Bamboo really helped with both of these. Even with the fresh bamboo it was impossible to bend it into a complete circle so this means that the loops had long legs on them. I didn’t cut them down too small so this means that they can act as stabilisers when they are buried into the ground. As there is about a foot of cane underground I’m hoping this will be enough to stop it being blown over.

The low feet also allows me to raise up the polytunnel on hot days to give some ventilation. Even with the feet just half buried it still seems pretty stable but allows air to get underneath (see figure 3).

I’ve had it out on the veggie bed for a week now and its still not blown over! The one thing that I may do another time is to put an extra straight cane across the top to stop it sagging inwards although again I think the long feet help with this as they stop the ends toppling over at all.

You also need to get hold of some muslin to put the pips in, I got some from ala cook as well as some of the wax discs for putting on top of the marmalade once it was jarred up. Putting the pips and pith in with the marmalade whilst it is cooking is key to getting it to set as they contain pectin which is what makes it set, I tried a muslin-free approach of boiling the pips and pith in a separate pan in my first year but that just lead to very sloppy marmalade!

One thing I didn’t write down at my Granddad’s was the quantities we used so I had to start from scratch which I didn’t think would be too tricky thanks to Google, however, I found all the recipes online varied massively for the amount of water and sugar to use. Instead of sticking to a particular recipe I took an average of the first few I came across so the quantities I used were:

• 8 Seville oranges (1kg)
• 2 lemons
• 1.8kg sugar (either preserving or granulated)
• 2.4L water
• 1 tablspoon treacle
• knob of butter

The first step in making marmalade is to juice all of the oranges and lemons. I cheated for this and used a food processor which made it really quick and easy to do. Once they are juiced you need to scrape out the pith on the skin and put this in the muslin bag along with the pips, I tend to use two bags as it gets a bit big otherwise.

You then cut the skin into chunks, the size of the chunks is purely down to taste. I do some in the food processor for speed and some by hand to get bigger chunks. The lemon skin is a bit tougher and more bitter than the orange so I do that very small.

Once you’ve done this put the juice, skin, muslin bag full of pips and pith and water into a large pan, the mixture should only fill the pan half full as it will boil up a lot later on. You need to bring it all to a gentle boil with the lid off until all of the skin is soft, which takes about an hour and a half.

At this point you need to add the sugar and treacle and bring it up to a rolling boil, this will take a lot of heat! I’m lucky as I’ve got gas hobs so I had it on full power on the biggest one and it still took a long time to reach setting point. Its at this point that you will realize why you need such a big pan, mine was only a third full to start with and it still nearly boils over (keep an eye on it at this stage as if it does boil over it will catch into a sticky fire, set the fire alarm off and take an absolute age to clean up, a bitter experience if you’ll excuse the pun).

At this point I put some plates in the fridge and sterilized the jam jars. To do this I put them upside down in a big pan and then poured in boiling water and boiled it for about 10 minutes, after they were done I put them in the oven on a low heat to dry them out, this also meant that they were warm when I added the marmalade to them which is important to stop them cracking.

After the marmalade mixture had been boiling for about 25 minutes I started testing it for setting point. I have a sweet thermometer and when it reaches 105°C it is supposed to set, however, I found that it didn’t so I had to do it the old fashioned way. This involves putting a spoonful of the mixture onto a plate that has been stored in the fridge, if it starts setting and forming a skin on the top of it after being put in the fridge for a couple of minutes then the marmalade is ready to be jarred up. I kept testing the mixture every 5 to 10 minutes but I found it took about an hour to reach setting point. Once it is at setting point add a knob of butter and stir it around, this will help clear the scum that forms on the top whilst it is boiling.

Finally I put it into jars, the quantities above will make about 7-8 jars. Then put a wax lid on top of it and it is ready for eating!

Admittedly we won’t have any fruit until next year but I am fairly optimistic that we won’t have people turning up in the front garden with an empty ice cream tub to take their fill of fruit. Maybe some overhanging fruit might disappear but I’m confident that any pilfering will be made up for the reduced bird numbers as the extra noise of traffic, pedestrians and cats seems to keep them away.

So far we have found the complete opposite as the conversations that were started over the fence lead to our neighbours generously offering up various produce of their own: cherry tomatoes, plums, runner beans and 3 lovely fuchsias. Perhaps the neighbourhood cynics would tell me that this generosity is just because they are after a punnet of fruit next year!

Personally I earn more than the national average, I have no dependants and don’t receive any tax credits. You would imagine that a “tough but fair” budget where everyone “shares the pain” would mean that someone like me would therefore be facing a higher tax bill this week. However, the reality bizarrely is actually the opposite. By raising the threshold for paying income tax Mr. Osbourne gifted me £200. Factoring in the 1% rise in national insurance that Labour announced and the new government is keeping I am likely to be taking home just £86 of this (less than you may imagine as they are also intending to raise the threshold in line with the income tax threshold). Sure with the VAT increase I am likely to be shelling out an extra £190 in tax when I buy things but the freezing of council tax for two years will mean that in real terms I will be paying under £100 more tax a year in the future.

This does not seem right that an above average earner is facing such a small increase from a “progressive budget”.

The part I find particularly annoying is that those that will be hit hardest are the poorest in society. The government loves to talk about the income tax threshold helping the poorest people in society but sadly this just isn’t true. It helps the people that are on low to middle incomes. The poorest people in our society are those people that don’t earn over £6,000 but instead rely on hand outs from the government. By cutting things like housing benefit and reviewing disability allowances as well as increasing regressive taxes like VAT it is these people that will find themselves worse off this week.

Mr. Osbourne, please stop lying to us, this is not a progressive budget.

By offering this the Tories are making a big concession to the Lib Dems although it is worth pointing out that the AV voting system is by far the least proportional of the four voting systems that have been discussed and I summarised in my last blog post. As it is still a single candidate electoral system it means that the big two parties could still benefit from it, pushing out smaller parties that have a loyal but small following who may miss out of the second preference votes (I’m thinking in particular of the Green’s after they won their first seat last week).

Despite it being the least proportional it is still a major concessions by the Tories. It is easy to see why this would be unpopular for them and their supporters, the left-wing vote in this country has been split between two parties in the past – Labour and the Lib Dems. Under the AV system it is likely that in many places the second preferences of these voters would stay on the left and therefore push out the Tories who relied on their opponents being split. It is therefore impressive that they are offering any sort of deal on this issue even if it is for the least reforming of the possible systems.

It is also worth noting how feeble it therefore was of Labour to also offer a referendum on this, they were likely to gain the most from such a system. It leaves the single constituencies that tend to help bigger parties more. They also had the least to fear from a stronger Lib Dem party as they do share more values with them than the Tories do.

Have a Proper Referendum or None at All

I must be honest and say that in general I am not a big fan of referenda, I’d rather our elected politicians would make the decisions on our behalf so this may sway my views but I really don’t think that having a AV vs. FPTP referenda is a good idea. It is pitting two very similar against each other. I also can’t see any of the main political parties getting behind the AV cause. The Lib Dems don’t really want it, preferring the more proportional STV system. The Tories will see it as a threat to ever getting in power again and Labour will be caught up in a leadership battle and the woes of opposition and won’t be too fussed about supporting an issue that they probably think was forced upon them after the expenses scandal. One group of people that will almost certainly be vehemently against it will be the Murdoch-lead press who will see it as a challenge to their ability to dictate who will win the election.

It is almost like we need to employ some really clever people to go away and think about what the best system for our country will be… oh wait… we already did that. The Jenkins Commission reported in 1998 that the best system to keep stable governments with an increased proportionality would be the AV+ system. Similar to the one that we will have a referendum on but with an additional proportional element.

If politicians are going to insist on ignoring experts advice and hold a referendum, at least give the public the option to select the recommended AV+ system. At the same time the referendum could include the STV system, sponsored by Lib Dems, could be included to allow people to really get behind the system they wanted.

Of course with no really backers to its name the AV system would probably fade into obscurity but I think it could still play a crucial role in Electoral Reform. With 1 traditional and 3 reforming options in my proposed referendum there is a large risk that the reforming vote will be split evenly between the 3 and therefore lose. The AV system would be an excellent solution to this problem and allow the electorate to select the system that they really feel is best for the country.
