codewritinfool··on Audiophiles in Japan Are Installing Their Own Power Poles
Explain to me how an amplifier is a power conditioner, please.
codewritinfool··on Audiophiles in Japan Are Installing Their Own Power Poles
A motor-generator is a better solution. Preferably with a big flywheel.
codewritinfool··on The Weedkiller in Our Food Is Killing Us?
I had a Yunnan tea habit of about a pound a month for 26 months then found out my thyroid function went to almost zero. Blood tests a month after I stopped showed heavy metal exposure down in the noise, so was it pesticides? Is it even related to the tea? I may never know. Now I'm on synthroid for the rest of my life.

Yes.
codewritinfool··on Firefighting foam heats up coal fire debate (2010)
Either I'm not reading what you wrote correctly, or you're misunderstanding what I'm saying.

I'm saying put it out. Less CO2 released.

codewritinfool··on Firefighting foam heats up coal fire debate (2010)
How much is a fire like this contributing to CO2 emissions? Seems like 60 million is a small price to pay if it stops ongoing burning and combustion products.
codewritinfool··on ATDT relief
Yes! Thank you. I've worked with Telit devices recently (which also have an AT command set) and my brain got it wrong.
codewritinfool··on ATDT relief
Yes.
codewritinfool··on ATDT relief
Oh man, this reminds me of a time that I got into trouble. We had a phone system (Isotech 228, IIRC) that had these boxes call OPXIs that let standard telephone equipment connect to the phone system. They provided talk battery and ring voltage.

We had a modem tied to an OPXI, which required that our dial strings in Telit (remember that? I liked it better than Procomm) start with "91,", which was 9 for an outside trunk, then 1 to select a trunk, then a comma for a pause. Then the phone number of the BBS site.

The OPXI messed with the newer modem speeds. One Friday I decided that we didn't really need the OPXI if I bridged the modem with the fax line, so I did.

I didn't tell anyone. That was a mistake.

Monday morning I showed up for work and my boss (the chief engineer and president) called me into his office. Uh oh.

He said, "Did you remove the OPXI from the modem line in the lab?" "Yes." "Why?" "Because we didn't need it."

He then told me about how he came in on Saturday, finished up some PCB artwork and went to dial into the board fabricator's BBS to upload the files (long distance), and kept getting failures to connect. He tried it a bunch of times before he heard banging on the front door. He went to the front and there were multiple police officers outside. They said there were multiple 911 hangups from this location and wanted to know why. He swore that he was the only one there and there were no 911 calls. They then wanted to come in and look around the building, so he let them.

After they left, he put it all together. The dial strings were set up to dial 91,1-areacode-phonenumber which dialed 911 emergency without the OPXI in the path.

He verified that the OPXI was no longer in the loop and was ticked off. He knew immediately who did it.

He said, "Things you do to systems other people use can have unintended consequences. Please think those things completely through in the future."

Good advice, and I still hear his voice in my head today when I'm reconfiguring something.

codewritinfool··on What These Medical Journals Don’t Reveal: Top Doctors’ Ties to Industry
I'm in the U.S. and I've had a root canal. I was only given a local and nothing more. I've never experienced the high and not knowing where I was, and no pain meds for later. In fact, I drove myself home.
codewritinfool··on Ask HN: Which abandoned proprietary software would you resurrect?
Microsoft Image Composer
codewritinfool··on Leave Gmail in 10 steps
Not using Fastmail, but I'm working on this now. Bye, Google.
codewritinfool··on What we learned from 3 years of bra engineering, and what's next
With what my wife spends on other clothing, $350 for a bra that fits and is of high quality seems ok. I think this is a good market.
codewritinfool··on NIST Digital Library of Mathematical Functions
This is nice
codewritinfool··on Embarcadero RAD Studio 10.3 (Delphi, C++) Product Feature Matrix [pdf]
I'd buy that too.
codewritinfool··on Ask HN: Have you ever regretted working on a product?
Yep. A few.

One was a series of electronic game callers used by hunters to kill coyotes. I'm not opposed to hunting, and I realize coyotes are predators, but with the caller, the coyotes don't stand a chance.

The second was a commercial PC product that didn't end well. For me. It ended pretty well for others.

codewritinfool··on Helium kills iPhones: MEMs oscillator sensitivity to helium [video]
It is conceivable that a powered chip clocked with a MEMS oscillator that is seriously off-frequency may latch into a state that is unrecoverable so long as power is applied.
codewritinfool··on Ask HN: Which is the richest IT niche for a 2-3 years project?
Nobody can answer this with certainty for you. If they could, who wouldn't be pursuing the same thing?

No, they are not.
codewritinfool··on Ask HN: Over 60 = no engineering jobs?
Interested in moving to St. Louis? I'd like to talk to you.
codewritinfool··on Zener diodes have coupled quantum noise that travels at c [pdf]
This was going to be my reply also. Seems it would be easy to set up a similar experiment with zener diodes and achieve the same results. In fact, with DSO's readily available these days, this should be reproducible in every university worldwide, and it would be cool to see attempted correlations across much greater distances.

Here's hoping for an OSX version.
codewritinfool··on Ask HN: What was the one book that you read and it actually changed your life?
I would suggest "I Am A Strange Loop". Same author.

codewritinfool··on Two French rivers disappear underground in cracks and sinkholes
I feel sorry for the "lakefront" houses that have a big empty pit in their back yard. They've tried several times to fix this, and I'm pretty certain that there was a special assessment associated with each attempt.
codewritinfool··on Ask HN: Software development after 40, how do you keep the fire?
Mostly I'm just rambling and drinking Bell's "The Oracle", so take this for what it is worth. Maybe not even 2 cents.

I've been coding for hire since I was 13, and I'm in my early 50's. I always loved electronics so about 20 years ago I moved into embedded. I left the rat race of the latest language / latest libraries etc. I code in straight C and maybe some assembly if the task demands it.

I feel I get better every year, and the demand and pay shows that. The only thing I've noticed is that I'm slower to anger and more willing to listen to ideas, but like you said, my BS meter is very sensitive.

About the only age-related thing I've noticed is that it takes me longer to heal when I injure something. I can't participate as easily with softball on the parking lot or even frisbee.

I'm not an expert; I truly learn something new EVERY DAY. The difference now is that I can often out-think my coworkers that are in their 20's, all from experience. About twice a year I get to work on things that have never been done before. Mostly, though, it is state machine after state machine, but to be honest, I've never found a lack of motivation with embedded.

It seems that there will always be a need for firmware down on bare metal. At least I'm banking on it, and plan to be doing this for 20 more years or so. As far as "making it big", I don't care. That was never a huge goal. I just wanted to provide for my family and retire some day.

PC app development is a different story. I was burned one too many times and cannot concentrate to write ANYTHING. Why that is (or what the difference is) I don't know.
