Are you talking 2:1 volume, or length?
I've built a few in my time, and found that one of the best designs that was used had a huge compression chamber in the back (probably 3x the volume of the barrel volume). In that respect, you get a large charge, funneled down to a smaller diameter barrel.
Even with hairspray, it let out a pretty good *CRACK* when fired.
Our intiial designs were somewhat of a failure. Just one long piece of tubing, and the ignitor stuck in the rear cap. Didn't work well, after seeing the design mentioned above, we worked off of that base design.
Now that this topic is up on slashdot, it's got me thinking of making a dual-chamber potato gun, complete with dual ignitors activated by one trigger.... perhaps even have a set of valves to spray in the combusting material (always hated having to take off the caps...) hmmmmm... could be done in a weekend!
To be honest, though, when I buy things on e-bay, I expect feedback after the seller RECEIVES PAYMENT. At that point, my end of the transaction is complete, and the seller should have already updated my feedback profile accordingly.
Anyone who waits for the buyer to leave feedback (regardless of what that feedback is) is just waiting to ding the buyer if said buyer is unsatisfied.....
I understand that once roads are built, that's a huge one time cost that may never happen again at one time.
However, I would think that maintenance of said road would still be expensive. Especially with large semi trucks etc. The roads can't take care of themselves.....
You are right. Most criminals out there do not want to waste time with this. But I would think the "smart" ones would actually want it to appear as if nothing is wrong.
For instance, let's say someone robs a house. It's obvious right away if the door is kicked in and the jamb is busted. However, if the thief is selective about what is taken (which, they never are) and also has the skills to not cause a lot of damage on the way in, then those "selective" stolen items may go unnoticed for some time, which gives the thief more time to fade into the noise.
Do some reviewing on this before you jump in and buy.
I've been thinking of getting this program, but one thing holds me back -- they don't have it to the point where it will play full frame (720x480) video in realtime yet. Of course, most of the stuff on the net isn't full frame (most is maybe half res)...
I wanted to use this to view my DVD rips I've made myself, but it doesn't look like it's fast enough. Check out the Faq's section for other little issues (scanning through divx files is one)...
Not necessarily a better solution, but you could buy:
1 USB CF reader (~20$) 1 512mb CF card (~140$)
Of course, it doesn't have the same form factor as the USB keychain, but you would have data portability... and you could buy extra cards for more storage.
Of course, it's still more expensive than a CD-R.....
Actually, doesn't the DVD spec top out at 10mbits/sec?
If they're referencing a 5mbit/sec transfer rate (minimum, mind you), then the media would have no problem sustaining a divx transfer, but would probably puke on most (if not all) DVD-spec'd files.
And I'm not trying to flame or be rude with this comment... bear with me... but why do you need ethernet surge protection? In my situation I have 2 lines run out to the garage (detached) so I can play drums/guitar etc, but they're buried deep (6 feet) and grounded....
I've always wondered if surge protection would help....
The only thing I really have to complain about with the lt1 (in the f-bodies, anyways) is the spark plug wiring. Who came up with that convoluted scheme of routing them behind the power steering pump etc?
In addition, I'd like to throw out my two cents. I own an LT1 equipped Camaro, and love the feel of the car. It's not exactly nimble in the turns, but the out and out growl and torque are impressive for a sub 25000$ (new) car.
As I understand it, the block for the LT1 has remained fairly unchanged for a few decades... Now, what's in a block? A piece of steel, bored to X dimensions etc. The real fun at that point is introducing a new cam, new timings, different fuel map ratios, etc. The engines of today may have their roots in early 1900's design technology, but things such as aluminum heads (and aluminum block for the ls1, if I'm not mistaken) and better mapping of spark and fuel metering lead to improvements in the overall performance and efficiency from the engine.
And I do get 30mpg on the freeway.:) Gotta love that!
A few of my better friends at work get severly upset or depressed that they are making extremely good money doing mundane tasks. I used to be the same way. My manager put it into perspective, however, by stating that the work we do is key to the running of the business, and while it may not be the most appreciated job of the century, it most certainly is a high-ranking job.
I would have to say, depending on the music style, I can.
I've found certain bands that I'm into don't compress well at 160. So, my solution? VBR, 192 minimum. Even though it takes more space, I have a better feeling that more of the actual music is represented.
I've heard artifacts in cymbals being played at 192, so giving it the ability to code up to 320 VBR is a godsend.....
I haven't had any experience with fire before, so maybe I'm way off base, but why would you want to seal off something that smells? I know that the baking soda might help, but I'd think airing stuff out (granted, not in the middle of winter) would do good too.
No, you'd have to buy a new key. And that may or may not be more expensive than going to sears etc and getting a copy made.
Granted, making a backup is much much less expensive (in the long run) (of a game) than buying another if your copy gets scratched/eaten/set in a microwave. But the car analogy isn't good......
If you knew a file specification, let's say it had "static bytes" at the beginning (identifying it as XML, doc etc.) At that point, if you load the document into a Sparc, if it is unrecognizable, it could attempt to swap the first several bytes (10? good round number) and if it matches the spec, then continue, otherwise say "Nope, invalid doctype".
You make a good point, but the 2 things you recommend would autmatically happen.
1. Joe Blow, who doesn't want to see anything but the e-mail from his family, will learn to filter out all that spam via that spam precedence. 2. All isp's will halt e-mail at the routers, seeing as it churns up bandwidth better served servicing their customers.
In the end, it would be a crap shoot. Spammers just wouldn't put the proper (whatever) in the headers.... kind of like when people rip a cd, they quietly ignore the copy-protection bit...:)
I'm not too familiar with ZoneAlarm, but couldn't you use that as part of your "security" solution?
You said you have the hardware firewall/NAT solution -- well, you've probably multiple boxes on the network. Why not make one of those the "zonealarm" passthru box, and control all packets in and out through there? (afterwhich, you could place the hardware firewall to protect this box....) Seems like the easiest solution to me.
And yes, I know, some people probably don't have the spare hardware to do this.....
Actually, I think the ultimate bonus would be that you could use it in ANYONE's car.... Think of it...
I used to have all sorts of weird set-ups in my car to accomodate different formats (cd when I had a tape deck, minidisc when I had a cd player etc...) but this would be cool if you wanted to share your collection on a road trip with someone else's car.
As long as the signal doesn't drift, tho. I've tinkered with the FM transmitters, and the only thing I've really liked about them was convenience. Speaking of which, rental cars these days should all come with CD players, standard.....
As far as minidisc is concerned, that would be my main priority -- how does it sound?
I currently own an MZ-R700 (I think that's the model...) and it rocks. My only real gripe is the headphone out is a little low (it doesn't have a truly dedicated "line out" for use with a stereo etc) but other than that, for the occasional work out, or music at work, it's awesome. I would be curious to see what people think of the hard disc based mp3 players in retrospect, because I have thought about purchasing one; I always go back to the minidisc recorder tho, because of the quality I get from it.

Find me one disk that can push more than 40-50MB/sec and I'll give you a cookie.
So, Serial ATA would be faster, if the disks were faster.

geesh.

Well, in that instance, # of injuries compared to number of total travellers would be more in-line.
Like you said, all in interpretation. People can make statistics say anything.
Somehow, I don't think I would equate portable with 64 bit PCI slots.... is there anyone that's crammed them into a laptop or similar device?
That's why it's called "work" :)
A few of my better friends at work get severly upset or depressed that they are making extremely good money doing mundane tasks. I used to be the same way.

I've looked at work differently ever since.....

"But I really, REALLY need to use the bathroom! It's starting to smell funky in here!!!"
Just wait until you want to buy a house...
Once you've been paying on your house, they keep upping your limit (mine is at 20,000 and there is no reason for anyone to need that much on a CC)
