ASUS laptop is on the way. My wife says that it is "hers", though she has never been a computer-user. She just wants me to have something to use when the power goes out.

Internet seems to be full to stupid people. Two idiot minors post a racist video and then few other idiots post their address and send them death threats:

I wanted to make a new thread about freedom of speech and racism for minors but there aren't many details about what kind of disciplinary actions were taken. I hope they don't get kicked out of their school, go wrong paths, and end up in prisons later in their lives.

You know you're old when you go out for Mardi Gras, and the kids give you beads for not showing your junk.

On a related note, I saw a rather disturbing commerical tonight. Cialis is for erectile dysfunction, but they say that it may cause swelling of the tongue. Maybe I'm missing something here...?

That would explain why it's called wedlock. I always thought the ring was the exchange of an article of monetary value in order to validate the marriage contract.
According to Arabic, maybe muslim, tradition, it is.

Say, why didn't you fix that Cern thing? It was just a loose plug.

I can certainly relate to their problem. Those can be the worst sorts of problems to find - in particular, when you have an intermittent break inside of a wire. I've seen situations where a wire will ohm out correctly three or four times but still fails when you try to run the system. If the failure points directly to the wire or circuit as the issue, one can often deduce that this must be happening. The worst situations are when it causes a brief system-wide hiccup that is difficult to even catch. Those sorts of nightmares have been a significant aspect of my adult life. For a good number of years, I was basically in the business of troubleshooting these sort of problems in large systems [ie. that was my bread and butter]

I once had a real oddball problem with a CMOS [maybe even TTL] Analog to digital converter in a new circuit I was designing for something... The chip would intermittently fail to output the proper value, but the voltage on the input pin was correct and a new chip didn't fix the problem; nor did a second new chip. It turned out that even though the voltage was currect, the current could actually drop slightly below the min acceptable value, which is unusual to see if the voltage on the pin is correct, and was due to a series of resistor errors that all happened to be high. That one had me pulling my hair out for days.

You've described such things before, so it actually occurred to me as soon as they announced the problem that you should be over there troubleshooting.

I had three slices of cheezburgerz last night.
Not bad. Just like 3 cheese burgers, only from another universe.

I suspect they have some fairly competent people there already. But I could tell war stories all day. You never really forget these things... at least I don't. And the more agonizing the problem was, the more fun it is to remember.

So true. The more trivial the cause of the "problem" the more agonizing the route to getting the customers (and their engineering staff, etc) to acknowledge the fix and implement it. I was on a troubleshooting mission on a paper machine in the Hudson valley years ago, along with a man that I highly respected, and who was highly respected in the industry. We split up the paper machine based on our main experiences, and I hunted him down a bit later to tell him where the problem was. We convened a meeting of the engineers, production-staff, and supervision of the mill, and my old friend had me lead the meeting and present the findings, since I had found the problem. The engineers and most of the production staff refused to listen to me, though my solution was well-founded, and my old friend got up and said "Let's get out of here. You're not going to make another ounce of salable paper if you don't do what he says." The production manager and the mill manager followed us out of the meeting and asked my friend if the findings were real and he told them that they were. They shut down the paper machine and made the required changes, and went right back to making paper. When a 40+ year-old machine like that that stops making usable product, you ought to get right back to basics and ask why instead of pointing fingers.

Some can be painful, but we have to take those in stride.
