Resolving Sound in RealPlayer 11 under Ubuntu Jaunty

Following an upgrade from Ubuntu Intrepid to Jaunty, I lost sound in RealPlayer. This is how to get it back.

Firstly, open RealPlayer 11 and go to Tools>Preferences>Hardware. Set the Audio Driver to OSS and untick all the boxes.

Execute the following code in Terminal.

sudo gedit /opt/real/RealPlayer/realplay

and thereafter replace the following text in Line 52,

$HELIX_LIBS/realplay.bin "$@"

with

padsp -n RealPlayer -m RealPlayerStream $HELIX_LIBS/realplay.bin "$@"

Restart the system. You should now have sound in RealPlayer 11 under Ubuntu Jaunty.

Visit to Stonehenge, Windsor Castle, Legoland and Greenwich

This Easter we spent a few days near London to see things, which we missed on our previous visits to the nation's capital.

Day 1: Stonehenge and Windsor Castle
On Day1 we visited the famous heritage site Stonehenge in Southern England near Salisbury, believed to have been built starting from 3100 BC. It is widely believed that the Stonehenge was built as a temple to mark the Summer and Winter Solstices. On the day we visited it was cloudy, which was perhaps not ideal for taking photographs with a normal digital camera. We barely managed to get a few good snaps, but with a digital SLR it was a different story. A few pictures....
Later in the afternoon we visited the Windsor Castle. Windsor Castle is perhaps the largest and oldest inhabited Castle in the world. It is one of the official residences of Queen Elizabeth. It is the finest castle I had visited so far in my life. St. George's Chapel is certainly the highlight of the visit. We also managed to get a glimpse of the day's last Change of Guard. A few photographs from the visit....

Day 2: Legoland Windsor
On Day 2 we visited Legoland Windsor. Legoland Windsor located in Berkshire County in England, is a children's theme park built completely with Legos. Yes, I mean Legos, the tiny plastic building blocks used by children to build a variety of things. This place provides a source of inspiration for the children, on what is possible to build with Legos. The children really enjoyed the day at Legoland. The best part was Miniland, a Miniature city. We visited Madurodam in Netherlands a few years back and Miniland though not in the same league, is very good. A few photos from Legoland Windsor...


Day 3: Greenwich
On Day 3 we visited Greenwich. Greenwich famously known for its Prime Meridian (0° longitude) is located a few miles south of Central London and close to the famous business district, Canary Wharf . The Prime Meridian is located at the Royal Observatory, the home of GMT.
Later that evening we visited Queen's House and National Maritime Museum, both good in their own way. We thereafter passed underneath River Thames via the Greenwich Foot Tunnel to reach the other side.

Thus, concluded our Easter break.

Google Maps - Street View

Yesterday, whilst looking for some directions on Google Maps, I came across this amazing feature called Street View, which gives a street level view of things from a driver's perspective.

To use Street View, you need to drag the icon of a man just above the zoom slider onto a street of your interest. It covers most cities in the UK and probably the world. The amount of detail available is just mind blowing. This feature strikes me as just a step away from real life virtual driving, where one could drive around major cities from the comfort of their seats. Hats off to Google....

“Earth – The Power of the Planet” by Dr. Iain Stewart

I finished watching the DVD “Earth – The Power of the Planet” presented by Dr. Iain Stewart this weekend. It took me a couple of weeks to watch the complete Two volume DVD with approximately 5 hours running time.

This DVD was an attempt by Dr. Iain Stewart and his team to explain the various forces (Volcanoes, Oceans and Ice, Atmosphere and Impacts from outer space) that shaped our planet so far and how the actions of the human beings over the past few thousand years are leaving an indelible imprint on the planet’s delicate ecology. It is difficult to pick what is best in this DVD, because every section is amazing and breathtaking. However, I most liked the section that is close to my heart termed “Rare Earth”, which is about an extraordinary sequence of events that led to the shaping of the planet that we live on today.

The conclusion by Dr. Iain Stewart and his team is our planet, because of its resilience, will eventually survive whatever the mankind may throw at it – but we humans may not be that fortunate.

The contents of the DVD and the presentation by Dr. Iain Stewart were truly exceptional. I thoroughly enjoyed every minute of this very informative DVD. To illustrate a point on how good the DVD is - by the end of the first DVD I was so impressed with what I saw that I felt like chucking my career in Oil & Gas and go and work with Dr. Iain Stewart on whatever project he is likely to work in the future. I would rate this work by Dr. Iain Stewart and his team as “Top notch” with an outcome that is “Truly brilliant”.

My advice is BUY this DVD set, if you are interested to know how our Planet was shaped over the past 4.6 billion years to its present state and how we humans are affecting its delicate ecology. If you are unable to BUY the DVD at least try and borrow it from wherever possible.

Fixing Silverlit X-twin R/C bi-wing's Tail

In the New Year, my children persuaded me to buy a Silverlit X-twin R/C bi-wing airplane (which was on Sale) in Maplin whilst I was looking for some hard drive enclosures. This post is about how I broke the tail of this toy plane and how I eventually fixed it.

Back at home on that day of purchase, the children didn't need to plod me to set off to the nearest open space near my house. The first fifteen minutes or so we flew the airplane quite well. On couple of occasions, it got stuck onto lower branches of nearby trees and on one instance it flew into a fenced backyard of a neighbour's house. We managed to get the airplane back on all the occasions. It all seemed to go okay until I pushed my luck just that bit more, wherein I flew the airplane into some high branches of a tree. It took some out-of-the-box thinking to get the plane down. During the process of bringing it down, the major part of the tail got ripped apart thereby ruining the airplane's ability to fly. The children were really disappointed with what had happened. To wipe the disappointment off their faces, I promised that I would get the tail fixed. This post is about the quest of getting the airplane's tail fixed.

Immediately after we got back to the house that day, I searched the internet to see if anyone had faced a similar problem in the past. I also checked whether I could buy a spare tail from the original manufacturer. My search was futile because no one had faced this particular problem before, probably because it is very unusual and rare for a airplane to loose its tail, unless it had a mishap similar to ours. Furthermore, the original manufacturer only stocked propellers and not the tail sections. We thus had to give up the idea of fixing the tail at least for the time being.

Whilst shopping at a supermarket a couple of days later, I found an empty cardboard placeholder for Garnier Moisturizing Cream, which I felt might do the job for us. I later went on to cut a few different sizes of elevator and rudder sections. Unfortunately none of them worked. I got onto the internet to see, if there are any photographs of the tail section, so that I could cut the cardboard to match the exact dimensions. I found one as below.
I cut the cardboard to match the dimensions as per the photograph. Still we had no luck in getting the airplane to fly. The problem was most probably due to the fact that the weight of the cardboard was different in comparison to styrofoam. We felt that we might never see this airplane fly again.

Last weekend, whilst eating at Costco (off styrofoam plates) an idea suddenly struck upon me - why not use these plates - especially because the material and thickness resembled that of the original airplane tail section. We had a couple of spare plates left over, which we expected would do the job for us.

This weekend, I cut the plates to match the dimensions of the earlier cardboard sections, duplicated from the manufacturer's photographs. I glued the sections to the airplane hoping that finally we might get this airplane to fly. Once outdoors we did a few test runs on our driveway to see whether it was worth the trouble we had taken and to our surprise the airplane flew. Later in the afternoon, we went to a nearby open space to fly it for a longer duration.

Surprise! Surprise! the airplane flew really well. It was nice to see the smiles back on my children's faces. During the course of that afternoon, we learnt to do circular manoeuvers and make soft landings, which we didn't manage on the misfortunate first day.

A few photographs of the exercise of getting the tail fixed onto the airplane.....
