Reasons you should learn other languages like lisp, scheme and haskell continuations,macros,monads and method pattern matching .... just to name a few

Here is how to create a sequence and two of the most popular functions to use on a sequence. CREATE SEQUENCE <seq_name> INCREMENT BY <integer> START WITH <integer> seq_name.NEXTVAL seq_name.CURRVAL Example: CREATE SEQUENCE MySeq INCREMENTED BY 1 START WITH 1

I can't wait to see Laurie, fall is my favorite time of year and miss when I don't spend it with Laurie

Another day is going by, traffic was brutal 2 hours to get to the train station to pick up my friend and coworker brent. Today I am working on data warehousing. Last night I spoke with Laurie I am so proud of her because she is working so hard studying for finals. Down side today I have a dentist appointment and am having a filling replaced with a mold.

I'm back. Took the standard red eye back into NY. Arrived early like 7:20 am my parents were nice enough to pick me up then I went sleep promptly at 10am. Woke up like 5pm and that was my sunday. On the upside spoke to my friend arizona.

Well, I am telecommuting in Southern California again, and am being quite productive with work and Laurie is staying up very late every night to fit more studying in. I am usually in bed before her for work in the morning. My arm has been bothering me again so I have been hitting the pool before work and after work. This is the first time I have been able to do this since the community pool just opened up. Evening have been okay filled with lots or reading and eating dinner with Laurie. On the reading chopping block have been Atmel AVR Programming, Assembly Language and .net Mobile Programming. Little bit diverse I guess but all embedded programming a lot more embedded than I am used to.

Resources - Great Place to start finding information http://www.avrfreaks.net/AVRGCC/ From what I am told the best c library and environment to use with AVR's, Also been told that WinAVR is used in conjunction with AVR Libc WinAVR http://winavr.sourceforge.net/ AVR Libc http://www.nongnu.org/avr-libc/ http://savannah.nongnu.org/projects/avr-libc/

If you need a lisp IDE you have 3 good choices 1) Emacs -> lots of programmers use it. 2) Slime -> recommended, live interaction with lisp run time. 3) Allegro CL IDE - Commercial Lisp Product

I enjoyed this weekend and celebrated my mom's birthday. I went to Manhattan to treat my Mom and Dad to brunch at the boat house. Then walked around the city with my parents and friend Brent. Saw the Top of the Rock ( Much better view than Empire State Building with no lines). Other than that spent some time relaxing, watching Underworld Revolution and Studying atmel programming working on a Atmega8 Schematic. Now on to the wonderful work week

Well today Laurie has to do a Fetotomy in school and now am learning something new. A Fetotomy is when you have to remove a dead baby cafe from the mother cow surgically.

Me and Laurie were getting back from San Francisco and was about 4am the day Steve Irwin Died, Laurie room mate pointed it out to us. At that moment it didn't bother me very much because I was so tired. But it hit me the next day and since them has really bothered me. I am not sure if it's because he has little kids or such a giving person to the world through his conservation and teaching efforts. Either way the world lost a great man, and I wonder who will carry on his legacy. http://www.crocodilehunter.com/ The family wants people to give to his charity Wild Life Warriors if you want to give in his memory. http://www.wildlifewarriors.org.au/ RIP Steve Irwin you were a good man!

Think my cold has stableized and isn't getting worse I think that it's a good thing. But getting better is slow work.

I love it every time I get to visit Laurie in SoCal. This time started off good, Spent time studying with Laurie. Then right after I arrived I caught a cold, I feel like dirt right now. It's so much harder being sick and telecommuting for work than being sick in the office especially because your under the gun to produce and all I want to do is crawl under a rock and die. On a brighter note, this past weekend I got to hang with an old SigEp Buddy of mine Craig Reiser I am hoping my luck will change by the end of the week Peace Steve

It's been a long and great summer having Laurie home for the summer. I am not looking forward to another year of flying back and forth to California. Already I have bought my first two tickets to Ontario Airport on JetBlue. By the way JetBlue is great but flights are usually late just about every other trip I take to the west coast. Better get back to work.

8.13 Is It "2>&1 file" or "> file 2>&1"? Why? One of the common questions about the Bourne and Korn shells is why only the second command will redirect both stdout and stderr (13.1) to a file: $ cat food 2>&1 >file cat: can't open food $ cat food >file 2>&1 $ Although lots of sh manual pages don't mention this, the shell reads arguments from left to right. 1. On the first command line, the shell sees 2>&1 first. That means "make the standard error (file descriptor 2) go to the same place as the standard output (fd1) is going." There's no effect because both fd2 and fd1 are already going to the terminal. Then >file redirects fd1 (stdout) to file. But fd2 (stderr) is still going to the terminal. 2. On the second command line, the shell sees >file first and redirects stdout to file. Next 2>&1 sends fd2 (stderr) to the same place fd1 is going - that's to the file. And th

Complex decisions are best left to your unconscious mind to work out, according to a new study, and over-thinking a problem could lead to expensive mistakes. The research suggests the conscious mind should be trusted only with simple decisions, such as selecting a brand of oven glove. Sleeping on a big decision, such as buying a car or house, is more likely to produce a result people remain happy with than consciously weighing up the pros and cons of the problem, the researchers say. more ... http://www.newscientist.com/article.ns?id=dn8732&feedId=online-news_rss20

My friend Chris Taylor (aka Zona) is in town, it's a good week. Also I am busy building planogramming software for my company.

The last six months have been very hard for me personally, but getting stronger, more independent. I can be very impatient, and have a hard time figuring out what I want out of life and work. Things are becoming clearer and find that simple things in life really make me happy, being around people, clear things to do, building new things, the gym and being just around Laurie. Commuting by car or plane is not one of them. This year is going to bring change just like last year did that's the only thing I can be sure of other than Loving Laurie. I am hoping to be able to cut through some of the bull in my head a be a more productive creator, mostly in the programming arena. Good luck everyone and have a happy new year. Steve
