Can an electronics student join?

I knew when I wrote the description I was describing you.

The calls I get are usually for jobs where the situation is already dire. Project hugely behind schedule, someone has royally screwed up, something has hit the fan, things like that. If I'd say yes it would be a matter of days and the paperwork and moving company would be lined up. The best one so far was where they wanted to send an aircraft to our local landing strip in town to pick me up for a meeting (I can walk there in minutes).

Maybe he has been overwhelmed by all the good advice.

eople are bad here, try alt.revisionism.

intelligence".

You thought you were. I have actually met some knee-jerk liberals. They are just as obnoxious as their right-wing counterparts,and no less silly.

Because they tend to be attached to silly ideas that haven't been tried in practice, I'd judge them to be marginally more dangerous than their right-w ing counterparts, who tend to attached to ideas that more-or-less worked in times gone by. Of course burning fossil carbon for fuel is an idea that mo re or less worked in times gone by but has become too popular to allow it t o persist.

The bottom line is that a knee-jerk reaction can save your knee in the shor t term, but more careful thought is required to preserve the world for the longer term. Liberals are prepared to contemplate change, while conservativ es want to avoid it.

Quite likely, since reverse DNS of his posting IP address doesn't resolve. Time to do some snooping:

The block is owned by Viasat: which means satellite internet on Exede/Wild Blue.

Summary: He's somewhere in the Phoenix AZ area. Nmap is returning an AIX signature, probably because I'm using a 2007 version of nmap. My guess is it's really an Exede satellite router. The computer is an Apple something running Lion or before because of the open port 625 (Open Directory Proxy). Port 1720 might be an H.323 softphone on the Mac or an Exede VoIP "voice adapter". No clue why port 19 (character generator) is open.

Well, if he is a troll, I think he'll be disappointed with what were, by and large, very measured responses.

The desired response would have consisted of diverse lectures on the nature of unmoderated Usenet groups, interspersed with claims about his ancestry, personal hygiene habits, and mental health.

But trolls are not what they used to be.

I made a mistake in my analysis. He's not in the Phoenix AZ area. That's where one of the Exede satellite downlink gateways is located. He could be anywhere in North America within LOS of one of the 4 Exede satellites.

I didn't read all there responses, but I would have expected at least one suggesting that beginning electronics students have more appropriate and extensive resources at their school than on Usenet. At least that was the traditional response to anyone asking for help with his homework. I'm undecided if this is a good idea.

That's the traditional newsgroup hazing, most of which is a thinly disguised probe attempting to determine the posters intellectual, moral, political, and social standing. It really helps to know whom I'm insulting. Posting in sci.electronics.design often adds probing questions on one's position on RoHS solder, anthropogenic global warming, Obamacare, and a few odd electronics related issues. It's handy to know these because discussion topics invariably drift in these directions, depending on a persons areas of interest and expertise.

Yep, times have changed. These daze, a troll might really be a bot or the NSA.
