...that's a defensive earthwork. If you look carefully on the side of the road, you'll see where they also built up the hills to the west. To the water side, you can see anti-tank / landing craft barriers (little black poles).
That's one reason I work the brass cold. I only use the heat to anneal it. I also work in a open air shed, so the air changes out rather quickly.
There are a lot of metals that are extremely dangerous when heated. I know of at least one death resulting from forging galvanized steel, so this is a very important aspect to keep in mind, thanks for bringing it up.
Annealing is the process of softening the metal, not hardening it. For magnetics such as steel, you anneal the metal to soften it for working, then harden by taking it up the critical temp (point at which it looses magnetism) and then cool it abruptly. This hardens and embrittles the steel. To keep the steel from then breaking, you temper it. Tempering adds softness to the metal at a controled rate.
As to heating the metal to high temps...I do that all the time. Above a white heat though, the carbon begins to burn out of steel, so we try to avoid using that high a heat. I work all day at between bright red heat and bright yellow and I do this to soften the metal for use.
Interestingly, I worked brass for the first time in my forge this week for a project. I had read that I should anneal it, then work it cold until it hardens from the hammering and anneal again. Its true. As I worked the metal over my anvil, I could feel it hardening (it also generated its own heat, which was hot to touch, but not the temps I see in Blacksmithing). After a brief period in my forge, cooled down, and it was back to normal...until I started hitting it again.
You are right that as far as I know, polishing doesn't harden most metals. I will often "pack" a knife blade when done with it hammering it at a low heat. This supposedly tightens the grain. Ah well. A machinist and a blacksmith enter a bar....
Uh..beleive it or not, there are some of us that don't have broadband. I live way out in the country, but have a fully networked house. I use Suse for all of my computers except for one Windows PC for games and one OS X for adobe work.
When I want to install Suse on a new computer at home, its very nice to have the whole thing!
I live 15 miles from a state capital and the best I can get is 26.6kbps and even that falls out occasionally. We shouldn't be proud of our speed increases until we can get more people up to par.
How about putting rails down the medians of the major highways and establishing stations at major cities. Then offer fast direct connections and slower regionals. The eminent domain issue is solved because the state already owns the median and the traffic would jump once people see the train go by twice their speed.
I've seen this down to a limited degree in cities where there isn't room for the rails, so they put them between the lanes.
When I forget and leave the garbage bag on the floor instead of taking it out to the dump, and she shreds it into millions of fouling smelling pieces, I don't beat my dog. I take note and try to remember not to be so vulnerable.
Glad to hear that Brian found Jesus. We let Him out a few months ago to get a bit of air and next thing we know...He's gone, poof, nada....
Could someone please post where Brian put Jesus so that we could come and get Him? Oh, just to make sure, our Jesus weighs 27 pounds and is black and white and likes to play fetch...
Very true, however none of the listed items are even close to the power and usability of a system with fans. If one were to scale up any of those technologies to the power (as in productive abilities) of a system with fans, then the costs become a major factor. Therein in lies the rub, cost is a major factor. If I can have the same ability with a fan driven machine which is $200 less than a fanless one, in the environments listed in the original post, then it will sway many people.
Headphones or put computer out of the way. Besides, have you ever been to a real concert? The ambient noise is much stronger.
2. What if you're using the computer to learn how to speak foreign languages?
Then you will be able speak in traffic. The real world is much louder than most computers.
3. What if you're using the computer in a library?
HVAC systems are as noisey, so are people clicking on keyboards.
4. What if you're using the computer in a soundstage?
Then you're doing something wrong. Of the number of soundstages I've visited, they all keep their equipment in an adjacent room for this very reason.
5. What if you're using the computer in a recording room?
See above.
6. What if you're using the computer in a theater?
Unless you're running the show, then you had better put that computer away and enjoy the show. If you're running the show, see #1.
7. What if you're using the computer in a home theater?
The try watching things other than silent movies. Again, if you place the computer in the correct location, its not an issue .
8. What if you're using the computer in a bedroom?
Then you either have a very tollerant spouse who doesn't mind the clicking keyboard or bright screen, or you need to learn to love white noise...besides, it helps you sleep.
If Jupitor is 43 light minutes from the sun, and earth is 8 light minutes from the sun, then the correct equation for the round trip from Sun to Jupitor to Earth is: 42*2-8 which would equal 76.
I actually did have a substantial part or my CD collection (including my printer CD - jeez) stolen, but they left the computer. Since I'm a hardware nut, my computer always looks like it just exploded all of the room, so it must have scared the burglar away. Good excuse for a messy system?
Well? Actually, I err on the safe side just because. I use bios passwords and user passwords, have a hardware and software firewall.....on my computers at home....which DON'T have internet access!
Okay, so they will again...one day....please God.... ______________

Good arguement, please explain minumum wage since there simply is no way a person can live on less than $6/hour?

_____Hahaha! 43*2-8=78! Messed up my own nit pick!

That's not a horse, its a DUCK!
....who keeps crapping in the recycling bin. Will you please quit that, it bothers the janitors!!
