My uncle took this photo of me a couple of days ago before my convocation :) PS: If you use the D700 (this might apply to other Nikon DSLR cameras) and you are dissatisfied with the skin tones (like I was for over a year!) change your Picture Control to Neutral and hue to minus one step (every thing else keep at zero, may be increase the sharpness a step or two). After I did this I was so happy with the skin tones I started using more of my JPEGs which means less RAW post processing! ------------------------------------------------------------------------------------------------------------------------------- At the end of my studies I want to gave thanks to the following people: 1) First, I would like to thank my heavenly Father, our Lord Jesus Christ, and the Holy Spirit. You see, God is really great, but the amazing thing is that He expresses His greatness through love and wisdom. In 2003 when I graduated from high school I was just a lost young man in a big scary and strange world. I knew nothing about life, I knew nothing about love or women, I knew nothing about higher education...needless to say I didn’t know much about anything. But the one thing I wanted to know is God, and to see Him work in my life. My average in grade 13 (last grade of high school) was 93% and I had taken all the courses I liked, that means: science (physics, chemistry) and math (calculus, algebra, etc). So when the teachers at my high school found out I haven’t applied to any university they were stunned! So my concerned teachers arranged for me to meet with a counsellor to talk about my future. So I went to the appointment and the counsellor talked to me about the importance of higher education and a successful career in life. I remember her finally asking why I wasn’t planning to go to university and I simply replied something like, “God has a plan for my life, but I don’t know what it is. He has a plan for my career, but I don’t know what it is. I can’t move ahead if I don’t know His will. I want to find my God-given talents so I know what to study.” I still remember the look on her face as if I was delusional, she simply raised her eyebrows and didn’t blink--she just stared at me for a couple of seconds and the appointment was over. That same summer I prayed to God to give me a job as I had applied to few general labour positions, just any job and I remember it was a Sunday night when I cried out to Him. I was new in Canada, no job, no money, no close family members, no friends, no plans for the future (except to know God’s will for my life, to witness Him work in my life, and to obey Him), and I just wanted to find a work, any work. Monday morning I got a call to a warehouse where I worked for the next four years. I didn’t know if I was going to work in the warehouse all my life, or if God will show me His will for my career and I will go back to finish school. I didn’t know anybody who God spoke to them in regard of something, so I was just hoping and believing that the same God who spoke in the Bible, and who said He has a plan for our lives, will speak to me and will tell me what His plan is! Anyway, I prayed daily to know God’s will and I worked there really like I was going to work there forever—I wasn’t going to budge to the left or right until I knew God’s will (I was so desperate to see Him work in my life like I read He did in the life of Joseph.) Of course, I got criticized from everyone I knew: family, relatives, classmates who were still in contact with me. People just didn’t understand. I am telling you this because while people thought I was working at the wrong place, God knew what He was doing. You see, in my teens I loved building remote controlled cars and building mechanical devices but as I moved to Canada I forgot about my passion for mechanical things. People also didn’t help: they kept telling me to become a pharmacist like my grandfather, or a doctor, or an engineer because those professions are so esteemed in society. But I just wanted to be loved and accepted by someone for who I was; sadly, that’s almost impossible in the Middle Eastern society. To almost all Middle Easterners: you are what you do and how much money you make. So God put me in a warehouse, and people thought it was a random warehouse, but it wasn’t. My boss (a Chinese man) was an awesome manager—someone I truly enjoyed working for because he was easy going (but firm when needed), generous, and wasn’t trying to prove anything (like he had power over us or anything like that, he just did his job and we did ours). My boss noticed my love for mechanical things, and sometimes he would ask me to fix things--like a paper shredder that stopped working, or put together the new conveyor system we just purchased--and so I started to feel that old love for mechanical things. I realized how happy I was when I was working on something mechanical. And even though people wanted me to be in university at that time, studying just whatev

Ok, today is cloudy and I felt in the need to put my head somewhere else for a while... to dissipate my own mental clouds. So I said to myself: Let?s play with wires! Let?s feel the adrenaline rising in that moment of plugging and not knowing if it will work or you will burn the electric installation of your place, or get electrocut! Nothing better than a risky thing to distract you from any current thoughts. Well, yes, of course it was not as exciting as I wanted it to be, but yet I spent an interesting afternoon matching wires and diassambling hardware, with some good results. But not the best ones, that?s why I am posting this here. I need some advise from real wire people... I know that many of you are engineers, or technicians familiar with audio systems. I am just a good observer, I really know nothing about this, but as Einstein said "The simple act of paying attention can take you a long way."... I agree. At least it put lots of paralizing fears away. The thing is that my 12-years-old Aiwa player passed away some days ago... anyway, just the radio worked for the last 5 years. But if I was keeping it was because it didn?t finally die and also because it had very good woodden speakers. Now, finally is caput... so as I am a recyling person, I thought of trying to use them for my computer. I currently have two ordinary desk speakers, nothing spectacular at all. I remembered I had kept a pair of broken computer speakers from my old computer, which are as the ones I use. So I disassambled them and took away the wire with the plug that goes in the computer. So I had this wire actually made of 2 (red and white), and one wire from each Aiwa speaker, also made of 2 (black and black with a white line). Cool. What I did was first to cut the used and dirty parts of the wires in use, and peel the copper wires to get some new and clean area to make the connection. Afterwards I had to decide how to make the match, because I had two wires from the speaker and only one wire (but with an internal separated wire) for each speaker in the wire with the pin to plug. So, making it in a way they wouldn?t touch, I matched the cooper filaments of the black wire (speaker) to the external copper filaments of the other wire (plug), and the black with white mark (speaker), with the filaments of the internal wire within the wire (plug). Ok. Then I prayed and I plugged it in the computer. Of course nothing was going to happen, bad I mean, I thought because there was only the computer with power. It would just not work. Well, it worked! And the sound is clean and clear, so the connections at radom I made I must think that are ok. BUT.... as you may imagine, there is a problem here: The volume! Because the speakers don?t have power on their own, so they are taking energy from the computer and it is not enough. So here is where I ask for advise or any ideas on what I could do about it. In the meantime what I did was to configure the computer to work as having cuadraphonic speakers, and so I plugged the little ones (little but they have plug of their own) as second speakers. So basically now I am getting a tremendous sound and at a very good volume level (normal), as you may imagine, but it would be perfect if I could make it explodeeeeeeee! You know what I mean... :-P
