Re: Quite Impressive

I have fiber optic to my house and I live in rural Iowa. About 3 miles out from a town population 760 and the next town has about 7600 people. It's a local company so that's why we have fiber here. You can get phone Internet and cable TV from them.

Not an easy to read map but it looks like they provide fiber internet in most of a roughly 14 x 11 mile area. But there is a big hole in that of 5.6 square miles. They don't provide fiber on the lake.

Re: People don't run red lights when they know there is a camera on.

But I saw a person run a red light with a police car beside or behind them.

Not sure which because I was about to turn left when the left turn arrow turned green. I was glad that I saw them in time to stop. And I was unhappy at first that two cars went through the red light. Until I saw the second car was a police car with it's light on. ;-)

I have seen it one other time. But then I'm a bit paranoid at left turns now.

Re: go out in the rain and watch the clouds light up

I had a bigger one come down near me in late 1992.

I was inside so I don't know if it was raining. But reports on the news said people saw the clouds light up. I just remember the big boom. Sounded like a sonic boom from a supper sonic jet.

I looked out the windows to be sure neither of the two big (yard wide) natural gas lines within a mile of the house had a giant fire raging from a leak.

I remember the year because I was changing my first born kids diaper at the time.

Re: Burroughs Large Systems There was never an assembler for it.

Learned a bit about the Burroughs systems after the merger with Sperry. Apparently some people had a hard time believing there wasn't an assembler.

It can take a bit of time to wrap your head around that. But hey, the compiler writers just need to know what binary to put out. Not much different then spitting out assembler code.

Re: Interference.

But valves can be sensitive to vibrations to. It would depend on how they were biased. If the logic was running in a too linear of a region they might perturbed by vibrations. And the drivers and receivers for the delay lines might well have had some linear amps.

Best tool for anyone drilling or nailing into walls. Non-contact AC Voltage detector, I like the adjustable voltage one. You can make it more sensitive for 24 V AC wiring or less sensitive to get a better feel for where a wire is. Never assume it's 100% right, but they are wonderful.

I first learned about them when I was having my dead dishwasher replaced. The installer used one to test that we had the right breaker turned off. The dishwasher was hard to turn on, so we couldn't just try to turn it on to be sure the power was off.

Re: Kids!

Bah!! I maybe older.

My first pre IBM invented small computers was an RCA 1802 based COSMIC ELF running 3.579545 MHz. It could have run 6.4 MHz but by using the color burst frequency you could drive a regular TV from the "graphics co-processor" chip. Really a DMA driver chip that with the processors help could clock out bits and sync pulses.

All this worked with 4 K of RAM and about 2 K of EEPROM. I soldered all the chips onto the two boards. Only missed a couple of pins on the first go. ;-)

Speed was not that blazing as it used 32 clock cycles per instruction.

No shift lock key, It had a HEX keypad with a few other buttons. I wonder if the tiny basic cassette I never used is still readable...

Well if you can reach the switch on the outlet you can pull the plug. Most of the time. What if the plug only has bare wires coming out of it? I never saw a UK outlet so I don't know if the switch would help with that case.

Re: Fluorescents...

If you have an old fluorescent fitting just replace it with LEDs when the bulbs need replaced.

You can get LED tubes that fit in place of the fluorescent tubes. I plan to use the LED tubes that are made to be direct wired to AC without the ballasts. Some of the LED tubes are made to work with the fluorescent ballasts, but then you need to have a working ballast.

Re: The good news is that there appear to be literally trillions of possible battery chemistries.

That may be the bad news to. With so many possible battery chemistries it takes a long time to find the few good enough ones. And that does not include the time to figure out the non-chemical variations of all those chemistries such as making the anode/cathode with the right sized pores for that chemistry..

Re: The elevator did it

I remember an old wireless phone I moved into my home office started making a tick sound every once in awhile. When I kept track it was something like every 1 minute and 50 seconds. Finally realized it only happened when I had my cellphone on. I assumed the tick was when the cellphone checked into the local tower to say it was still in the area.

Was my motto until I discovered a disk corruption while doing a backup. Then I realized that the backup I was writing to was gone and that now had only 2 backups. Assuming the disk problem hadn't messed up either of them. That was when I was using tapes.

Now I consider 3 copies as a bare minimum when I tell people they should do backups. I keep 8 copies in my backup rotation.

Re: Ah, the days before memory protection seemed necessary...

The newer Univacs of 1979 had memory protection and I would think some of the earlier ones would have had it to. The 1100/80's I started on could address 16M words but a program could only address 262K words at once without doing bank swamping. If I remember correctly, you could swap banks whenever you wanted to, but the OS decided which banks were in memory.

Re: It's ALWAYS easy to sign up

I've learned that with Sirius Radio. So far we've gotten two used cars with Sirius Radios in them. The dealer sets you up with a free 1 year subscription then Sirius starts hounding you to continue subscribing when your free time is about up.

Note we never signed up but still started getting a ton of junk mail (I hate junk mail) to resubscribe anyway. Have to call to get them to stop because you can only unsubscribe online if you have an account and we didn't have an account because we never signed up. But they know who you are so there is an account...

Next car we get will have the requirement of the dealer cannot sign us up for Sirius Radio or we'll sue.

In an emergency, see if you have a key that fits. I unlocked a minivan at church with my pickups key from the same manufacturer.

In the US, most camper storage compartments use the same key. One of my camper locks froze up so I replaced them all to get a new key. Will keep the old key in case someone else at a campground loses theirs.

Re: recall and repair tumble dryers that burn houses down

Time to do my civic duty. Do send in all the warranty cards on appliances.

First sorry to all the Whirlpool dryer owners

I apparently didn't send one in for my old dehumidifier in my damp basement. Well the cooling coil was getting matted up with dust so I was looking online to see if there was a "how to video" on opening it up for cleaning that would be simpler that what it looked like to me. When I googled the model number I saw that there was a recall on mine. Seems that a fair number of them caught on fire. Maybe not always burning the house down, but it sometimes did.

The manufacturer had a good recall. Send in the model sticker with the cut off power plug. Get pretty much all your money back. No receipt needed.

Re: Michael Fish...

The ~20 m meteor that exploded over Russia a few years back did happen to come down on the same day as another asteroid was coming very close to earth. They were in totally different orbits, but there really are a lot that come close.

NorthIowan

If you want to worry about meteors hitting the planet.

Keep an eye on https://www.spaceweather.com/ towards the bottom of the page.

Nice chart of all know asteroids coming by in the next few months. The ones with pink backgrounds get within about 1 million miles and red background is closer than the moon. Do understand the sizes are very rough as they are estimates depending on brightness for all the new ones.

For reverence, meteor crater in Arizona is 1186 m across and was made by a meteor about 50 meters across. And the one that went boom in Russia a few years back was estimated to be 20 m or so.

The new ones have names like 2020 JX1 where "2020" is the year it was discovered and the "JX1" gives an idea of when in the year it was found.

Oh, 2020 JX1 is about 60 m and goes by on June 29th at less than a million miles. They just found it a few weeks ago so not sure if they have a real good orbit figured out yet.

Re: Of course it was going to hit the boat!

Well the 0.0001% of the time things can go sort of right.

I worked in mainframe testing in the early 80's. Some of the guys were into model rockets. We had a few Friday lunchtime launches.

The real memorable one was when the one guy improvised a 2 stage rocket out of a simple 1 stage rocket. He simply put the 1st stage rocket motor on back of the rocket.

Apparently, the fins on a model rocket need to be right on the end of the rocket. Or there was a fault in the first stage motor. Whatever the problem was, the first stage only sent the rocket up about 10-20 feet, although the rocket traveled a considerable distance doing very tight and fast loops.

We all had time to duck behind cars. But that wasn't needed as the second stage miraculously was pointed up when it engaged and the rocket flew out of sight. So at least that part went right.

Re: RAM clear on power off ?

Maybe restart could be changed to be clear RAM and reload OS. Although the clear part may only be needed for security.

But there would probably also need to be some sort of method in the BIOS and motherboard to do a forced clear of RAM and reload OS for those times when the OS goes TITSUP. The present holding the power button down would probably work with a few BIOS tweaks.

Re: move one probe to a different socket to measure current

At least for something like a 10 Amp range. Lower currents sometimes use the same sockets.

But then you can get a shinny new meter if you forget. ;-)

I've been tempted to get a new meter with Bluetooth, recording or voice output. Was having trouble with my camper last summer and I couldn't see the meter connected on the outside from the momentary button I needed to push on the inside. Six foot extension leads would have worked to, but they're not as fun.
