Actually that is exactly what I'm running. Got it doing a DMZ and guest wireless network among other things - very capable in terms of feature set and reliability, but a Linux box slaughters it in terms of Mbps/$.
The replies you've got so far seem to think that just because a router has gigabit ports that it can do NAT at gigabit speeds, which of course you've already figured out is nonsense.
For a standalone firewall box you might need to look at something like a Cisco ASA. Not cheap but they will at least specify the actual NAT throughput for whatever model you pick.
The other way to go is to roll your own on a decent PC with Linux which will get you a few hundred Mbps easily. For example a Mac Mini or FitPC will be fast enough.
It seems that those in it for money and distribution will opt for iPhone, and those in it for neither will opt for Android.
FTFY. But seriously, did these developers make ANY effort to size the market on each platform before making their decision?
I can totally understand why some developers have problems the iphone approval requirements. But its positively daft to make a business decision on only that basis and then be surprised later to discover that your prospective customers simply do not care. Surprise! They prefer a unified, tightly controlled, non-sucky smartphone experience even at the expense of some interesting apps.
Personally I'd go a step further. I would give up EVERY SINGLE THIRD PARTY APP not to have to go back to the Treo that my iPhone replaced. Maybe Android has come a long way since then but for the first time I am actually happy with my phone and not motivated enough to find out.
I know. They'll say, but, but, but... what if they hadn't used the master and just used each copy, then would it work? Sons, why do you think Psystar used the master copy? Because it's a business, and in a business, efficiency is money. That's why businesses set themselves up, to make money. The whole world is not with you on a holy war to destroy EULAs and the GPL. Even this rinkydink business wanted to make money. Theoreticals belong on message boards, not in business and definitely not in courtrooms, and even on message boards, everyone told you for years that this wouldn't work out if someone tried it. It's been tried. It didn't work out.... coming from Pamela, who revealed that Microsoft played no small role funding the SCO debacle though bogus license purchase.
If you follow patent troll cases for example, you would know that shell business are often set up by litigants for the sole purpose of facilitating a lawsuit. Once you've acquired your defunct IP, you set up a web site to demonstrate intent to sell a product. Sure it's not strictly necessary to test the patent but it can help when it come times to assess damages, and it garners judge and jury sympathies (especially if you can get it tried in the Texas east district).
So, who was behind Psystar? Dell perhaps? There's no chance in hell a startup box builder would go to these lengths to test a legal theory. Their vested interest in the supposed business was a pittance compared to the cost to fight this, so where'd they get the money?
Obviously, Psystar was staged for the exclusive purpose of being sued .
First of all, current kills, not potential difference (=voltage). Both 110 and 220V are plenty to overcome the resistance of the human body so from that perspective there's hardly a difference.
Yes, current kills... about 0.1 amps across the chest cavity would be lethal. So does it make any difference whatsoever if the outlet is rated for 15 A @ 220 vs 30 amps at 110? No.
Ohms law: I = V/R
Current is proportional to voltage. On contact with 220V, all else being equal, DOUBLE the current goes through your body as compared to 110V. That's double the pain, or half the skin resistance needed to be lethal. This is simple ohms law, it is NOT a situation like a spark gap where there is some threshold to "overcome" the resistance. Also, skin resistance is not a fixed value, it depends on moisture, the amount of contact area, and the amount of pressure on contact.
Where on earth did you get 85? Are you reading that off the power brick? Those figures are meaningless for this purpose - that's the total load the PS is rated to deliver, not the average load at the wall socket.
The Mac Mini has all the components and power management features of a notebook so it's going to be about as good as you can get. For less money, the FitPC or a second-hand laptop is probably the next best choice.
The bus has to stick to a route, which is why this works for initial deployment. However, imagine if rechargers were installed at every red light - little pop-up electrical contacts that mate with the cars when they stop, complete with a micro-payment system that accounts for each micro-fill.
Now you don't have to carry around loads of batteries.
I had an idea for how to do this - has anyone tried using a HTTP proxy, and having it split up large downloads across multiple HTTP range requests, each going out of a separate WAN connection?
In other words, given N connections to the internet: Small requests are load balanced by simply doing round-robin. When the response starts coming in, if the object size is more than say 10MB, the proxy goes and issues N-1 additional range requests across each of the other WAN connections for equal sized chunks (or sized in proportion to the speed of each link, if they're different speeds).
And this could be done a lot better with some additions to the HTTP protocol. A "stride" parameter for example...
Of course it is not trivial but I think for static objects it is imminently feasible.
In fact this is how *nix process scheduling has worked for decades, and it is extremely effective. Why ISPs haven't adopted it is a mystery. Although aggregate throughput isn't improved, the typical customer's satisfaction would be... overwhelmingly so, with the same infrastructure.
the shingle lines I've seen run coat with asphalt at around 200C
What does that mean? When they get hot does asphalt condense out of thin air to coat them?
I had to recompile a couple times, but it does actually parse:
shingle = adjective
lines = means "assembly lines" (subject)
seen run = means "seen running"
coat is the active, transitive verb, referring to the process of coating the shingles with asphalt
Or something like that. In other words, he's talking about how they're manufactured.
They say these can be installed by standard roofing techniques... I don't know if anyone else has ever nailed down asphalt shingles but it's about as low-tech as it gets. So the question is how do these interconnect electrically?
I could imagine a couple ways - perhaps there are contacts that need to be aligned prior to nailing. Either that, or they intend for an electrician to come in after the roofers and attach a bus bar or something. Anyone got the full story?
The future for residential solar is not in the highest-tech, highest efficiency panels. Rather, it will be the system which gives the lowest $/W after ALL costs, including installation, depreciation, and in this case, savings because it also serves as your actual roof. Sounds like a great idea to me.
It cracks me up how "taint" originally was a noun referring to the perineum - the region between the ass and balls/muff, and now all of a sudden everyone just uses it to mean "to soil". It's so fascinating, how language evolves...
Except that the latest crops are now patented. If someone's crops get pollinated with the patented strain, even unintentionally just by wind from a neighboring field, then he can be sued by the inventor and subjected to license fees.
Squeezebox Touch is Linux-based, and imminently hackable. Although not emphasized as a consumer selling point, it is certainly no secret and there is a very active developer community around the products.
Why do you need anything aside customers jumping ship from MS's OS? Seems to me that's grounds enough for a suit right there.
I was making the assertion in a sort of tongue in cheek way. Not only is it indirect and difficult to prove, it would also make for an altogether incredibly pathetic PR stunt. I'm questioning their intent to actually follow through with this beyond a fishing expedition.
Aside from customers perhaps decided to jump ship to a more secure OS, was Microsoft actually wronged in any direct sense here? Wouldn't they have to organize a class action for this to go anywhere?
The point is they can _make_ it for that, therefore it's viable.
The point is they can _make_ it for that, therefore it's viable. Duh. And if it's only $10/barrel then it is very viable indeed!
However, since the plastic is made from a barrel of oil in the first place, I'm skeptical that it could end up cheaper in the long run. Perhaps it appears viable considering today's value for waste plastic, but it might not be after the increased demand for the material is realized.
In the long run it will be evaluated like any other form of recycling - can we make it more cost effective to recycle into oil, compared to pumping oil out of the ground? Or can we recover more value by reusing it as plastic?
I would sure love to have a "real" camera from Apple. Strap some proper optics to the iPhone platform and you've got a killer product: photos automatically GPS tagged and seamlessly uploaded in the background to your iphoto library, with support via apps for any kind of online hosting, plus specialty stuff like time lapse or other artistic/scientific needs. Full HD video of course, perhaps even with wifi streaming to an apple TV for instant nostalgia. Price it to compete with entry level DSLR and they would capture a huge chunk of market share overnight. Maybe not the volume of the cell phone market, but great margins.
When you say 'either leg of the house power', you don't mean different power phases, do you? You can have great fun with co-connected kit (eg a printer and a server) when they are on separate power phases - sparks can fly!
That's absolute nonsense. It is done all the time, especially in data centers where a pair of outlets on opposing phases is wired with a common neutral. It gives you double the power for just one more conductor. Or for 3-phase, triple the power for two more conductors. It is explicity allowed by NEC (210.4, "mulitiwire circuits") and is perfectly sound wiring practice. Even a UPS will have its own outlets on opposing phases, because it makes for a much more efficient design internally.
The steel rebar and the copper pipe being in close proximity will make them act as electrodes on a battery. This will cause the steel anode to slowly be destroyed by the chemical reaction.
Is it a practical concern in your case? I doubt it, but if they haven't poured yet, it wouldn't hurt to wrap the copper pipe in some PVC tape. This will reduce the thermal coefficient though. Maybe just do it where it passes within a couple inches of the rebar.

Do you suggest we pretend the evil people don't exist? I imagine the story is intended to out them as the scum they are, not give them publicity.
Trust me they are thrilled to get "bad" press like this. Anyone who hires spammers, SEO outfits, direct mail companies, shills and the like knows full well that these practices are objectionable to most of society. Picking one firm and giving them front page coverage, saying they're the worst of the worst, is just going to send hordes of unscrupulous paying clients to their doors.

Er, let me rephrase:

Here is Apples's spec on the power usage: http://support.apple.com/kb/HT3468
I have confirmed 13W on a recent model using a kill-a-watt meter.
Fit-PC2 (Intel Atom) uses only 6W at idle, 8W full load.
