Well, If I was obligated to respond, and I'm not, I'd have to say that you couldn't have possibly guessed worse. For the record, I just corrected damn near everything you posted in this thread, with irrefutable fact.
It's simple, really. When you want to be taken seriously, you make sure your facts are right, before you throw them out for the whole world. Then, make sure that you can present them to the world, in an educated, intelligent manner.
What I don't do is come on here with boasting, outright lying and embellishing the truth. I don't come on here and say I can get 450HP out of a 450 CFM rig. I don't have to refute it, because it refutes itself. Call it a lie, embellishment, exaggeration, or whatever you like. The important thing is that it isn't a fact, and stating it as such, either implies that you are either exaggerating or lying. In this case, I'm pretty sure it's both. It's an exaggeration, because it's what he would like to believe, and it's a fucking lie, because it's stated as fact, with nothing to back it up.
As to what I do, if it's any of your concern, I am a Geotechnical construction Superintendent. All that should mean to you is that I am competent in a broad range of specialties, not the least of which is designing and building equipment specific to various jobs, and employing that equipment in a manner which is both effective and profitable. That means I design or modify equipment and techniques, to a specific set of considerations, and modify one or both as needed to meet a particular goal.
Equipment is equipment. I know engines, powertrains, hydraulics, pneumatics, electrical systems, from an automotive charging system, up to 200KW systems.
I am formally educated in electronic engineering, and emergency medicine, as well as various communications systems.
As to when or where I choose to utilize an insult, and the type of insult I choose to use, come on now. I always go with facts and details first. I do sometimes succumb to my old ways(20 years in the Army will tend to color your language a bit). The fact remains, I seldom lead out with it, but have absolutely no problem retaliating. The point you should take from this, is that it isn't the only weapon in my arsenal, and I much prefer to allow an idiot to prove himself an idiot. It's so much entertaining, when one demeans himself. My preferred weapons are simple facts.
As to what I offer, well, that is subjective. Sometimes I offer information, and sometimes I simply refute bullshit. If I feel an overwhelming need to assist someone, I will generally try to arm them with the means to find an answer, rather than just hand out an answer.
You see, without bragging, or boasting, I can say that my tech savy is sufficient to make me a healthy income, provide me with an ever changing set of challenges, and earns me the respect of those who require my services. The reason is that I get things done. My arguably abrasive personality, well, hell. What can I say. I'm an ass. Get over it.
Oh, and in my previous life...
If none of that impresses you, well, goddamn, It wasn't meant to. You asked, and I answered, with facts, as is my habit.
