Raydon Railway Great Woodlands Circular Walk

On The Front Line, Sport, Suffolk, Walking Hiking Navigating No Responses »

Dec 282011

There is a small free car park beside Station Farm at the beginning of the walk. The disused railway makes firm footing in the wet but if you follow this route when wet be ready for log-hopping along the way. The northern part of the walk is the most likely to bog down but at least at that point in the walk there is easy access to alternative routes on roads.

I recently changed the layout and the column resize effected the display of images and Picasa galleries. To overcome these issues I used the MySQL REPLACE command which made changing embedded HTML a breeze.

If you do not know how to run SQL statements against your database it is probably better that you do not try this as it may lead to serious damage to your blog, it may even destroy all your work so take care.

Start by taking a full backup of your database. Then take a copy of the wp_posts table so should disaster happen recovery will be simple and fast.

UPDATE wp_posts
SET post_content =
REPLACE(
	post_content,
	'width="800" height="533"',	
	'width="650" height="432"'
)

In the above example I wanted to replace all entries with a width of 800, height of 533 with 650 and 432 respectively. The entire database updates when this SQL statement runs. As a precaution consider making another copy of the table to test the SQL statement first.

Foxhall to the Nacton River Orwell Shoreline Circular Walk

12.9° C by mid morning, if it wasn’t for bare trees it would be difficult to distinguish from an early summer morning. This walk took me from Foxhall to Nacton, directly past my sons old School Orwell Park and to the river bank shoreline in Nacton, a popular place with walkers, runners and twitchers. Nacton shoreline is the River Orwellian equivalent of Piccadilly Circus on bank holidays, not even the mud was keeping people from enjoying the mild weather.

If you don’t like walking in mud then avoid this walk when wet. Even dry hot sunny days there will be muddy areas around the creeks and streams. Avoid the mud by walking on the high ground. My advice would be if you see the deep holes created by cattle full of water then turn back and use the road for that part of the walk.

Alternatively if you are the kind of person who takes string with you on a walk you will find plenty of old wood to strap to your boots to over the tough parts.

Perihelion: The northern hemisphere is closer to the sun in winter

winter solstice pivato Perihelion: The northern hemisphere is closer to the sun in winter

Winter Solstice Northern Hemisphere

In the early 70′s I went to Belmont School near Abinger Hammer, Surrey. Major Irwin took us for history, geography and for those of us with parents abroad took us orienteering on weekends while others went home. On one trip he explained Earth was closer to the sun during the winter solstice for the northern hemisphere.

Over the years I lost the detail in his explanation (that lesson took place more than 40 years ago) and each time we reach the winter solstice I berate myself for not looking up the facts and reacquainting myself with the magical story of how nature balances life with seasons.

Today, Tristan Gooley posted The Cloud Compass on his blog which includes a brief explanation of Perihelion (the closest point) and Aphelion (the furthest point). These words triggered the missing details from Major Irwin’s explanation so now I have something to search for in Wikipedia.

Major Irwin did not go in to detail, I was 10, but I do remember on a freezing cold morning doubting we could actually be closer to the sun than in summer. The following abridged text from Wikipedia explains Apsis.

An apsis, plural apsides, is the point of greatest or least distance of a body from one of the foci of its elliptical orbit. In modern celestial mechanics this focus is also the center of attraction, which is usually the center of mass of the system. Historically, in geocentric systems, apsides were measured from the center of the Earth.

The point of closest approach (the point at which two bodies are the closest) is called the periapsis or pericentre, peri, around, and kentron. The point of farthest excursion is called the apoapsis, apocentre or apapsis (the latter term, although etymologically more correct, is much less used). A straight line drawn through the periapsis and apoapsis is the line of apsides. This is the major axis of the ellipse, the line through the longest part of the ellipse.

batch render 300x195 How to batch render and stretch in Sony Vegas 11 Pro

Selecting batch render in Sony Vegas Pro

If you have prepared regions in a video which you wish to output as individual files Sony Vegas Pro has a simple script called “Batch Render” that will do the dirty work for you. However it won’t stretch to fill video for you and if this is a requirement then you need to change the script.

Research reveals Vegas Pro versions before 9 would handle stretching to avoid letterboxing too. However the default installation no longer does. This is how you do it:-

Locate the script directory (usually C:\Program Files\Sony\Vegas Pro 11.0\Script Menu)
Make a copy of “Batch Render.cs” and call it “Batch Render Stretch.cs”
Open the new file in a text editor and find the two lines that begin “args.OutputFile =”. You will find them around line 97 and 106.
Create a new line below them and add “args.StretchToFill = true;” (without the quotes (see below)
Save your changes, refresh the script listing in Vegas and use the new script to render files as before but use this new script instead

After your changes the code should look something like this:-

if (RenderMode.Regions == renderMode) {
	int regionIndex = 0;
	foreach (Sony.Vegas.Region region in myVegas.Project.Regions) {
		String regionFilename = String.Format("{0}[{1}]{2}",
				filename,
				regionIndex.ToString(),
				renderItem.Extension);
		RenderArgs args = new RenderArgs();
		args.OutputFile = regionFilename;
		args.StretchToFill = true;  // <------------ Add this line
		args.RenderTemplate = renderItem.Template;
		args.Start = region.Position;
		args.Length = region.Length;
		renders.Add(args);
		regionIndex++;
	}
} else {
	filename += renderItem.Extension;
	RenderArgs args = new RenderArgs();
	args.OutputFile = filename;
	args.StretchToFill = true;  // <------------ Add this line
	args.RenderTemplate = renderItem.Template;
	args.UseSelection = (renderMode == RenderMode.Selection);
	renders.Add(args);
}

If programming’s not your thing you can download a copy of the script ready-made by clicking here.

A hike from Brookhill Woods Foxhall to the Maybush Pub Waldringfield, Suffolk

Dec 112011

The weather report said ice so I decided to start my walk from my front door. Fortunately I live in the suburbs and less than two minutes away from a Footpath sign. I have walked this path many times but because of its location, beside the largest municipal tip in Europe, I’ve not been encouraged to do more than a couple of miles.

SDC12767a 300x225 A hike from Brookhill Woods Foxhall to the Maybush Pub Waldringfield, Suffolk

Saltmarsh on The Deben

Today I decided to walk past the tip, cross the dual carriageway, and beyond. All the way to Waldringfield where I would stop for lunch and then back along part of the Deben I have not yet walked.

That was the plan and it all worked up to the pub. A couple of miles down the river from the pub a signed warned that anyone continuing on the path would have to return the way they came because land erosion had claimed the path.

As I walked along the small country lanes around the lost river-paths I considered why the paths have suffered from erosion. The Deben moves fast and shifts a lot of sand at its mouth but inland its muddy and tidal. By the time the tide reaches Waldringfield there is little energy and the river flow itself is not fast. It is natural for a river to change course as it seeks the shortest route to sea but as it changes can we not walk around it? Perhaps that’s Naïve.

Suffolk Coast and Heaths are restoring the saltmarsh which will reduce energy from waves and help protect the remaining paths.

Bromeswell to Gobblecock Cottage a Circular Walk Through Rendlesham Forest

Forest, On The Front Line, Sport, Suffolk, Walking Hiking Navigating No Responses »

Dec 042011

I didn’t see a UFO, or indeed the lighthouse beams from Orford Ness lighthouse, and the only attraction in the forest is Gobblecock Cottage.

gobblecock hall Bromeswell to Gobblecock Cottage a Circular Walk Through Rendlesham Forest

Beyond the name Gobblecock there is little of interest (the cottage owners have chosen not to display the name, but the hall next door fortunately obliges should you be using it for a waypoint).

I would have liked to add this post to the Ancient Woodlands category but the area I walked was plantation all, but for a few scraps along the way. In woodland terms there is little to learn except for any natural event that collides with unnatural which in my case was to step aside to let a Land Rover Discovery pass.

A few vehicles were collecting north of the airfield where preparations for a motorcycle rally had begun. As this is a plantation I whole-heartedly approve and see no reason they do not open the entire forest to free vehicle access. Nothing within its boundaries bares any resemblance to ancient Britain and is a haven for non-indigenous creatures that have already replaced what was once here. Not a red squirrel to be seen. Why preserve something meaningless?

Dog walkers fill this forest, along with dog-shit, which is more damaging than motorbike and off-road vehicle tracks which at least do more to cut disease than spread it.

Other parts of this public area are reserved for activities such as shooting and archery. As these are not fenced off a different set of warning signs are used to scare off would be passers-by, although the chance of being hit by a bullet or arrow are enough to keep me away and I think they should allow them to be fenced.

“Smart Water” is used to protect against theft but theft of what? Wood? Surely hunters and archers take their kills and targets home with them? A Smart Water sign only proves there must be something worth nicking then, and I think I would admire any thief who tries to strip a hunter of his gun!

On one public footpath a “Members Only” sign is displayed but members of what is not clear. I suspect it’s an old sign as following through the path revealed nothing but a path through woods.

I detect an air of greed in plantations. Yes we need wood for practically everything we do (the chair and desk I use to write this for example), but do we need “KEEP OUT” signs, barbed wire and electric fences to protect them? These are tools used to define ownership and a desire for exclusive use. Without these delineations few would venture onto the land anyway, the plantation having destroyed the lands value for ordinary people already.
