I'm not so worried about the timing. That can be engineered pretty easily. Now, plainly, if the timing chain breaks on this thing, you'll have a lot worse problems than holed pistons and bent valves. The whole thing would probably have to be scrapped.
This thing, however, faces the problem of keeping a unidirectional slider lubricated and sealing on the power rotor, and on the valve rotor, adds to that the problem of a continuously made-broken seal, where the gap goes by.
One thing they don't seem to mention anywhere in the article is the fact that this engine will require forced induction to get much specific output, as it has no provision for a compression stroke. A sub-1ATM fuel-air charge doesn't carry a lot of oomph. This design would certainly use the force generated very efficiently - every bit of push in the power arc is used at no mechanical disadvantage. However, since the power arc splits 180 degrees of rotation with the intake arc, you'll be giving up some of that to get enough charge to burn, and it won't be compressed. The obvious inductor would be a piggybacked second, smaller rotor, timed as a compressor only, with its exhaust timing coinciding with the intake valving on the power rotor. That way, the power rotor could be fully charged in maybe 10 degrees of rotation, leaving 170 degrees for the power stroke - minus valve actuation time, which will be a significant problem. In a standard 4-cycle system, the valves have a good half-stroke (and often much more) to get open and back closed, and still, it gets tough for even very strong springs to make them keep up with the cam lobes at high rpms. This thing will either have to run very slowly, or come up with a whole new form of valving (the manufacturer currently shows the engine using conventional tulip valves).
I think they have already demonstrated how this engine will be useful - with an outside-supplied source of compressed gas. That lets the valves be open for an entire half-turn, and makes oiling the sliders much easier. Heck, something like this might bring back steam-powered automobiles, as it would generate its best torque at low speeds.
Hehe! As I was reading your post, I was still processing on that one... wondering if there was some practice of setting macs free into the wild or something like that. I hadn't yet refined the comprehension down to a typo of loser.

As an April's fool joke on April 2nd...
I was getting ready to jab at Michael for posting a joke as real, but it appears that I'm the fool here. This thing exists, and it does have hooks.
Google led me to the "
Tree of Life Web project"
1. Tentacles
1. Club with hooks. ...
Comments
Hooks are also present on the arms. This is the only genus in the Cranchiidae with arm hooks.
as well as several other articles. Bummer of a dateline, though.
In a closet, huh? Oh, you mean a properly ventilated equipment closet, not a regular residential clothing closet. Otherwise, he'll either have to leave the door open (letting the noise out), or be no better off than simply clipping the fan leads.
I leave my old systems, complete with several external SCSI enclosures, running all the time, and the noise doesn't bother me at all... of course, they're in the office down the hall.
There are a few instances where you'd be a fool to skip the extended warranty. As a customer, you can't always tell when, though.
Two examples, both from Radio Shack: When I worked there, ham radios had a 5-year extended warranty (TSP- Tandy Service Plan), for USD50. Particularly for the handhelds, which get bumped around all the time, you could just bring it in every year and say "it seems to be a bit off-frequency, and get it realigned. At the end of 5 years, it was as good as the day you bought it (which was already pretty good - they were outsourced from Standard Radio), at a cost of USD10/year (+ initial purchace price of about USD250).
The other example was headphones. I used to sell the USD20 headphones for USD45 all the time, adding on a 5-year TSP. Again, headphone cables take a beating. When you start getting that intermittent open (scratchy sound as you move your head), you bring it to the store, give your phone number, they crossreference that with the item number, toss your old one in the trash, and hand you a new one off the shelf.
Other than that, the TSPs were nearly pure profit for the company. We were paid 25% commission on them, at least for a while, as opposed to 7% on regular merch, 10% on forcefeed (the little connectors and stuff in the back), and 3% on computer stuff. If you have the time to look at the costs, benefits, and how the item will be used, you can occasionally find instances where they make sense. Most of the time, just laugh and walk away.
Amen! When I saw the question, I was amazed. What's next?
Ask Slashdot: I just received an automobile for my birthday. The fuel gauge indicates that it is nearly out of fuel. Does anyone know of a place where one can purchase more automobile fuel?.
This is one of those things we were taught in second grade. If he's been paying taxes, he's been paying for the library anyway, using it or not.
All I can think of is that the submitter may come from some benighted country without a public library system, or at least his local branch is small, and without ILL. That said, I get most of my reading from Gutenberg. I like the palmpilot formfactor for a book, and cspotrun is nearly the perfect reader app. When I want something that's not public domain, I get it from the library.
Note: Many university libraries offer a "citizen" library card, giving you access to their much more extensive collections.
Foxnews is using Skynews feeds. They were using a Skynews feed, when some commentator started lamenting the destruction of the benevolent beloved protectors and nurturers of the Iraqi people, and they cut the audio and started bringing in their own. Just as well. If I'd heard another few seconds of his pro-Sodom crap, I might have tossed a table through the TV. ...and yes, I know that's not how the pervert spells his name. I just think my spelling is more appropriate.
I smell a challenge.
Sure, we can pick on him through technology. We'll all stay nice and legal, and at worst, piss him off a bit. I've got to wonder, though... With more and more people using email, the likelihood of these guys pissing off somebody without our moral limitations increases. When are we going to start seeing news stories like "Noted spammer near death after brutal beating, police interrogating 5.6 billion suspects"?
With ifconfig I can use your 2^24 numbers for nothing!
Yes, on your own network, that's great. If, as he would be doing, since he registered the range, you are selling a product, and don't want your customers to get bitten by MAC conflicts, spoofing MAC has absolutely no benefit. It looks like the manufacturer of the dupe cards cut the expense of proper, coordinated mac addresses. In fact, I'd guess that every one of these cards had the same address. If you're selling to the home user who uses his nic only to connect directly to his cable modem, you can get away with it.
It doesn't mention all of Egypt working of the pyramids, because it doesn't mention anybody working on them, because they were already old by the time Abraham was born.
On that specific one, the driver is responsible for the safe functioning of his automobile. If you're test driving a brand-new car on the dealer's lot, and engine goes full throttle and crashes into their building, you are legally responsible for all damages. Of course, their own responsibilities to you, and the manufacturer's responsibilities to them, etc., mean that the example isn't quite as bad as it sounds. The point is, "The brakes (that's how it is spelled, incidentally) didn't work", "The tire blew", or "That truck splashed mud on my windshield just as I came into the curve" are all just other ways of saying "It's my fault".
I'd think moderators would turn off display of score and moderation, and read at -1. That'd be good slashcode - force my settings when you have moderation points. On the other hand, staying at -1 all the time keeps me up-to-date on the evolution of the "in soviet russia" thing.
During development, sure. Get the underlying logic and interface working, then plug in the authentication. If the final product has a back door, that's like selling locks are, undisclosedly, set up with a master key, which you posess.
Of course, you want to permit the owner to uninstall the lock if he loses the key... or just wants to disable security, if he thinks that's safe. Same with software. Put the authentication in a discrete file, so the person posessing the system running it can bypass the application to set up newly-defined security, just like the unix password files.(boot to access the partition containing/, replace or edit the file, reboot normally).
The mobility - yes. I read almost exclusively from gutenberg, using the best document reader I've ever seen, which also happens to be free, cspotrun (Get it, see spot run? A simple reader.) It does everything you are talking about, and there's no flicker in PalmOS. Edit the texts and prep them with any of the utilities - I generally just use makedocw. The format (tealdoc, aportisdoc, whatever it is) compresses the docs about 2:1.
All of your docs are always at hand, and open to wherever you last viewed them, and with the autooff function of palmos, you can shut off the light and read a book that, if you fall asleep reading it, saves your place and turns off the light.
An AC posted a followup about my IRS comment. Low-rated, likely to get missed, so I promote it here, and respond.
It's called the Internal Revenue Service, not the Internal Software Development House.
If you can't read the tax code (and fill out your forms with a pencil), then you're too simple.
I'll skip the question of electronically submitting pencil-on-paper forms...
What I'm talking about is that the code is so complicated that the group who creates it (based on legislative mandates) disclaims responsibility for the advice they give about it. They can give you an incorrect answer, then penalize you for doing what they say. There are actual conflicts within it, so you can get different answers by chosing different paths through the information. That's not logical. If they had to re-implement it as logical code, even pseudocode, and have the code work, we could then clearly state that it makes sense.
The fact that there is no "one correct answer" means that the system is open to exploitation by whoever has the best lawyers and accountants, and enough money at stake to make it worth spending some of it on lawyers and high-powered accountants. Following the law should not allow any ambiguity. If it's right, it's right, and if it's wrong, it's wrong. I don't want my well-being to be affected by an administrative judge's mood.
As he said, he's looking for an open-source way of doing it, not buying or warezing the Adobe stuff. While I don't object to making a copy of a CD so you can preserve the original, watching a show taped earlier, or reading a book for a second time without paying for it again (all things publishers are trying to get control of), that would be stealing. Personally, I'm annoyed that the government would suggest that in order to use what we've already payed for, we have to buy something else. It puts me in mind of the tax software issue. If the IRS themselves can't write the tax code as software code (and open-source it), the code is too complicated.
Any, back on-topic - I think there's something called "poster" to specifically do that with postscript files. pdf2ps the file, and work from that. I'm not sure if those utilities keep color, though.
On the mod to C, he may be kidding, but he's got a point.
Some latency issues can't be solved, except by reducing the latency. You call yourself an IT pleb, so I take it you're doing business work. If it's to supply email and web access to your business, the latency really won't hurt much, for most things. If you're planning to provide remote access over the link, find a lower-latency link. Interactive work with significant latency is very nearly impossible. Also, satellite latency is much more than roundtrip time. You're in a huge collision domain, covering what, 45% of the Earth's surface? I don't know how they resolve it, but I know that on my Sprint Broadband Direct (one central tower on a mountaintop, covering much of the northern Colorado Front Range), I get pingtimes as low as 40ms, and as high as 6000ms. Seems there's a lot of "waiting your turn". I can't imagine what it's like over satellite, but unless there's a seperate channel for every single user of the transponder, you face the same problem, only worse. In space service, you may have access to more frequencies than in terrestrial broadcast protocols, but you're still limited.
If you're going to be doing remote access, your users will probably be happier coming in over a 33.6Kbps modem link (if you can keep internal surfers under control).
Let's keep them all with the original, only two-day-old posting of this same story, here. No point in getting useful comments scattered across two stories. Cool slashcode idea - track stories seen, and extend expiration to some configurable value for unseen ones. It still won't avoid the 3 hour old dupes we sometimes see (if they don't read it at all, nothing can help), but it might make it easier for the editors to catch the forgivable dupes like this one.
