Customizing Ubuntu Linux 2
More fixesI wanted to add the current directory (.) to my PATH variable and tried to put the command in the .bash_profile file, but it didn't work. When I used the file /etc/profile it did execute. Open the file using the command <sudo nedit /etc/profile> and add the following line : <PATH=.:$PATH> to include the current directory in the PATH variable. When you log in the next time it will be set. If you read the Linux in a Nutshell book it says the following:
Bash reads these files:
1. /etc/profile. Executed automatically at login, first.
2. The first file found from this list: ~/.bash_profile, ~/.bash_login, ~/.profile. Executed automatically at login. Second.
3. ~/.bashrc is read by every shell, after the login files.
I coudn't get ~/.bash_profile and ~/.bash_login to work, but ~/.profile was executed. I put the following line <PATH=~/bin:"${PATH}"> in my .profile to add my bin directory to the PATH variable. Use the command <echo $PATH> to find out if all paths have been added.

Florida the sunshine state
During a more than one year stay, from October 2000 to January 2002, we (myself, my wife and our daughter) learnt to love Florida, its climate, nature, people and attitude. In September 2000 I was offered a job in US, working for Ericsson Inc as an ASIC designer. A company called Starburst located in Orlando performed the ASIC design project. Working for Starburst was like coming home. You felt like you belonged to the family from the first day you entered the company door.
The RTL design was done at Ericsson in Stockholm Sweden and Starburst did all the backend work, synthesizing the design, running timing verification and generating all test vectors. It was a busy but fantastic year and it was sad when we had to leave Florida to return to Sweden in January 2002. When we came to Stockholm it was -10C and two feet of snow on the ground.
What we liked best about Florida were the gorgeous beaches. The first thing we did was to buy the book Florida Beaches to start exploring all the places. The front page of the book says "The Only Guide to the Best Places to Eat, Stay, Swim, and Play on Every Beach in the Sunshine State". With the help of this book we went to beaches all over Florida from the Panhandle down to the Keys.
There are so many beautiful beaches in Florida but here are some we liked the most.

The New York City Marathon
It is a chilly morning on Manhattan when we board the bus at 6 am that will take us to the start of the New York City Marathon on Staten Island. I am one of 35000 runners that is going to run the race. I have had a good breakfast at the restaurant Manhattan Diner and I am ready for the 26.2 miles through five different boroughs; Staten Island, Brooklyn, Bronx, Queens and Manhattan. The bus takes us to Fort Wadsworth, which is located on Staten Island just south of the Verrazano-Narrows Bridge. Then there is a long wait before the start at 10:10 am.
As a New York City Marathon runner, you'll pond more streets in more parts of the city than many natives get to in a lifetime. The start of the race, Verrazano-Narrows Bridge is one of the highlights. The bridge was opened in 1964 and it remains the longest suspension bridge in North America, with towers half as tall as the Empire State Building. The top of bridge is also the highest point of the race, 250 feet above see level. On the other side of the bridge is New York's most populous borough, Brooklyn, home to more than two and a half million people. With more than 11 miles of the marathon in Brooklyn I have plenty of time to enjoy its size and diversity.
From the top of the bridge it's downhill. The tension is gone, the body starts to warm up, the sun is shining, there is no wind and the temperature is 10C. It is a perfect day for a marathon. We descend into Brooklyn and Fourth Avenue, which is a wide boulevard, lined with small stores and apartment buildings, with a church, synagogue or mosque seemingly on every corner. Running is easy and I have plenty of time to watch the surroundings and my fellow runners. I stop at every fluid station to drink. In the beginning I drink only water and after half the marathon a mixture of water and Gatorade. After 10 miles we reach Williamsburgh, one of the world's largest Hasidic Jewish enclaves. Much of Williamsburgh is going through a hipster-artist boom and many new restaurants and cafés are popping up. The Pulaski Bridge will take us to Queens where we stay for only 1.5 miles. The climb over the almost mile-and-a-half-long cantilevered Queensboro Bridge, completed in 1909 gives me a great view of the Manhattan skyline on my left. We enter Manhattan on First Avenue and hundred thousands of cheering spectators. My wife waits for me at 69th Street. A short stop a hug, a kiss and time for taking a few photos.
The neighborhood is now full of restaurants, stores, and modern apartment towers. Some older brownstones and tenements remain north of 90th Street. At 96th Street we enter East Harlem. We'll pass under the Manhattan approach of Moses's Triborough Bridge at 125th Street to cross the Willis Avenue Bridge, a truss swing bridge that dates from 1901. This brings us to the borough of the Bronx and mile 20. I am still in good shape. My legs are a little bit stiffer but there is no pain and no blisters. We stay in Bronx for only one mile and the Madison Avenue Bridge will take us back to Manhattan and Fifth Avenue. The avenue seems to never end and it is small ascent for several miles. At 110th Street the Central Park begins and on the left is the beginning of Manhattan's Museum Mile. When it is two miles left the course enters into the park. The park is hilly and it is up and down all the time. Now all of a sudden my legs start to give up on me. I have to run slower and slower but I force my self not to start walking. When I hear the people cheering at the finishing line I get some extra strength and I cross the finishing line with a big smile. I made it. I finished the New York City Marathon. I get my medal and I am covered with a big warming aluminum blanket. I am so tired and so happy.
All runners have a data chip mounted on one of the shoes. This chip will be read at automatic timing pads and your time will be recorded every 5K. All your split times and your finish time are stored and can be found on the New York City Marathon result page. To see my results, enter my start number 31363.

When walking around in New York City you will find wireless hotspots almost everywhere. Every Starbucks cafe has a Wi-Fi connection to connect you to Internet. When we were walking on Prince Street we passed the McNally Robinson bookstore. They had a small cosy cafe where everybody had their laptops on the table and was surfing the web. We walked in and ordered a cappuccino and a tea. The tea was served from a Japanese iron teapot and the cappuccino was the best I have had in New York. I took up my MacBook and in 30 seconds I was connected to Internet.

38000 feet above see level
I am sitting in an airplane heading for New York. We have been traveling for 5 hours and still have 3 more to go. I have read all the newspapers and magazines I can find and we have been served a tasteless lunch. Airlines try to save money on everything and the food is no exception. I have tried to watch one of the movies on the 12 by 10 cm display in the seat in front of me but lost interest pretty soon. I have navigated through the menu and read about the Airbus 340 and how to exercise sitting in your seat. Flying is boring.
But what cheered me up was the possibility to connect to Internet using the connexion by Boeing service www.connexionbyboeing.com. The service worked flawlessly and to impress on some of my friends I sent them an email telling them I am in a airplane on my way to New York. It is sad that this service will close down end of this year. I guess it wasn't profitable for Boeing. This blog entry is written and published using this service.
I will run the New York Marathon next Sunday. I am one of almost 600 Swedes that have the chance to take part in this great race. The travel agency arranging this trip is called SpringTime Travel www.springtime.se. Run in Swedish is "springa" which explain the name. I applied for the race more than a year ago and have been running more than 1500 km since than. I have lost 10 kg and was in perfect shape up to a week ago when I caught a cold. The cold is almost gone and race will take place November 5th so there is still some time to recover.
My wife accompanies me and we will spend some days exploring New York before the marathon. Tomorrow night we have a table reserved at the River Cafe www.rivercafe.com

I have decided to start my own blog. I have a lot of spare time after leaving my job at Ericsson the telecommunications company. They gave me 18 months pay so I will stay afloat until I find something else to do. My plan is to start my own company and do consulting work in ASIC and FPGA design. I never wrote a diary in my whole life but the prospect of having hundreds of readers makes it more thrilling. I will write about everything that happens in my life from running the marathon to building my own wine cellar. I will write in English although my mother tongue is Swedish. I would like to make contacts all over the world not only in Sweden. That is why I named my blog "New Horizons".
Welcome to my blog!

It was a great machine. I used it for everything, playing games like Pacman and Tetris, writing all my documents and organizing the house association. To find out more about the Apple and Macintosh history go to 
My fifth Mac is the one I am using today and the one that has given me the possibility to use it for all my computing needs both at home and at work. It is a MacBook Core Duo featuring a 2.0 GHz Intel processor (T2400) with two independent processor cores on a single chip. I had it customized with 1GB of RAM and a 80GB hard drive. It uses the same processor as many PCs are using and lets me install and run Windows XP and any Linux version I like.
