Instead of a nicely tuned radio subsystem you end up with design compromises, and the whole thing is a little less efficient.
Dropped calls, out of service areas, battery life, and ease of use are the "big four" in what sells a cell phone. Most manufacturers try very hard to maximize the first three by using the most efficient, highly-tuned receivers and transmitters available. They usually get publicly crucified otherwise. The cell phone market is by nature such a social climate that anything bad about your product gets blown entirely out of proportion and can be devastating to the sale of that model. Word of mouth is paramount.
So I assure you, the multiband systems in the cell phones are highly tuned, just the same as any multiband HT. If they run out of room they don't just cheapen the tuning - they either make it bigger or don't include all the bands. It's the better business choice for them. There are also other gotchas like spectrum purity in the transmitter, and THAT will get the FCC on your back in a real quick hurry if you try to cut corners.
I was thinking along the same lines. You have three basic issues in the desert:
1) exposed vents / heat. it has to be able to stay cool and either have a filter on the vents or no vents
Doesn't the iPad lack vents? Otherwise you almost need to screen/filter them in. Could be tricky. Someone may make a laptop case for a specific model or models of laptop that have a filter over the vent locations? Camera could be a problem for the ipad. (you can get them removed, and apple can offer the service iirc)
2) exposed keyboard - you could use a keyboard cover, and use some rubber cement, doublestick tape whatever to seal around the edges. keeping the trackpad button clean could be challenging. Most laptops support trackpad clicking anyway so you may not need the button to stay working.
3) exposed ports - I don't think this is going to be an easy one without a ruggedized design. Good packing tape over any ports you're not using for starters.
It doesn't look like the poster is concerned about a drop-proof machine, he's just trying to keep the sand and dust out of it, so most ruggedized designs are overkill for protection (I don't think "waterproof" is on his list!) and will be underpowered as a result due to cooling issues.
As far as "more usb ports" goes, get a hub. Most net books are only going to have 1 or 2 usb ports anyway, and hubs are cheap to replace. I'd expect usb ports to wear out quickly though in a sandy/gritty environment.
This has to be the most biased write-up I've seen in a while
I was wondering about that when I read it. Kinda sounds like they're pulling facts up out of the sand too...
Throw in multiple bandwidths for the CDMA 2G/3G technology used by Sprint and Verizon Wireless, and you quickly get so many technology and frequency variations that the phones can't easily be designed to support them all. Adding the circuitry and multiple radio tuners to support every possibility quickly causes space, power usage, and heat issues -- and higher costs.
Oh really? Adding additional radio tuners (of which only one is going to be turned on at a given time) causes heat and power issues? Makes me wonder whose laws of physics HE obeys...
While that's certainly true, I also think it's more a case of convincing them "Yes you really do have to go. Just try". At that age, their gauges only seem to read either Full or Empty.
And anyone that as a kid has ever tried to catch a duck or goose on takeoff knows you'd better be prepared to get covered, 'cause it's gonna happen.
I can't imagine a guinea pig being harder to bathe than a typical cat - smaller teeth, smaller claws, not as strong, no bred-in fear of water.
My cats on the other hand, come in the shower with me. But that's something you need to start really early with them, and keep up. I can just picture trying to bathe a guinea pig... get a shower with glass doors. fill it up with a couple inches of water and the shower head on. Walk into the bathroom and just toss them up over the glass. Watch them ricochet repeatedly off the inside of the glass, trying to defy gravity and avoid the water. And finally at last, submitting. (or breaking the glass I suppose) Would make a great youtube if nothing else.
They by themselves are quite clean, you don't have to bathe them anywhere near as often as a guinea pig or dog for example.
Problem is, they are scavengers, a bit like a ground vulture. In the wild they'll eat anything they can catch or steal/find. They have a stomach to eat rotten nasty things and not get sick, but if you happen to get some of that it'll make you ill quick. Domestic indoor cats of course don't have that issue. A guinea pig for example, is a vegetarian iirc?
I was thinking on this too, we don't have to put diapers on dogs or cats. But it just must be the "nature of the beaste" to not be easy to toilet train. It may simply be the case that monkeys don't have sufficient warning, control, and capacity to "hold it" if they have to go. Sort of like having to pull over every 45 minutes when you're on a car trip with a four year old passenger. The diaper is probably not their regular choice for the monkey, but more to prevent a mess if things get unpredictable.
And then there's the whole thing about monkeys (chimps mostly) entertaining themselves by flinging poo. The picture looked like a macaque, I don't recall hearing about them flinging poo at the zoos like you hear from time to time with the chimps. And a macaque would make a much better service animal just for the small adult size. (chimps get big and very strong, some have been known to outright beat up their handlers)
thx for that link, that site reminds me so much of those black and white compact ads in the back of the old magazines with all the really cheap little toys. But I actually found a few interesting little novelties, and for that price you really can't go wrong. Buy three things and TWO of them don't work and you probably still come out ahead.
If they were doing it some other way it would probably be illegal. But since it's their product and their store, within those bounds, they can make their own rules.
At least that's how the law is set up atm. If you want a piece of their action, you have to play by their rules. If you don't like it, sell your own product and make your own store and you can do whatever you want, is what they will say.
Apple will say that it duplicates existing iPhone functions and will refuse to accept it.
yepyep. that's their favorite rejection reason. "it competes with us". Most businesses can't just tell someone else entering their market "nope, that would compete with us, you can't do that."
I don't think even "program defensively" sums it up properly. How about "the user's ultimate goal is to BREAK the program, and they're crafty little tykes."
it wasn't a hack. It was as simple act of intrusion without authorization.
One could argue semantics in that he was authorized, but he was incorrectly authenticated. IE he used an authentication that wasn't his, and then did what that authentication entitled him (was authorized) to do. Authorization worked perfectly. This is a case of an "authentication failure", but in the sense that the authentication process didn't do it's job, but in a way that allowed when it should have denied. (in contrast to the usual interpretation, denied when it should have allowed)
If there's a road nearby and they're worried for the kids, I'd be asking why the entire playground isn't fenced in? Do they allow the "normal kids" to play in traffic?
"rack mount"? most racks don't accept full size towers. I'll try to ignore that minor oversight and press on....
So he had to plug in the cables for the hard drive, but not install the hard drive itself, that was already installed for him?
Heck the motherboard was already installed and most of the wiring attached. Over 75% of the work was already done for him. This whole thing was a joke.
This was like a cooking contest that involves seeing who can be the fastest at pulling prepared courses out of the fridge and stuffing them into the microwave.

and I suppose it goes without saying, don't feed them after midnight or it really gets scary?
We had one of those cuties subbing the other day. Fair sight of a change from the usual guy that looks like he belongs on Tour D'France.

Slashdot is reduced to publishing stories about "Service Monkeys"?
Stay tuned, tomorrow's story will be about servicing the monkeys.
They are filthy animals.
They by themselves are quite clean, you don't have to bathe them anywhere near as often as a guinea pig or dog for example.
Problem is, they are scavengers, a bit like a ground vulture. In the wild they'll eat anything they can catch or steal/find.

and if they find a way to get rid of the fans, that'll remove all moving parts from computers, which will be a good thing
I don't think even "program defensively" sums it up properly. How about "the user's ultimate goal is to BREAK the program, and they're crafty little tykes."
Competent users maybe?
As far as "programming errors" go, I'd label "expect competent users" as "#1".
the only way to secure the system- is don't let anyone into the system
Where is my "+1 insightful" when I need it??!

You quoted the right passage without knowing it
before it has been delivered to the person to whom it was directed,
That's the stipulation they used in the ruling.
If there's a road nearby and they're worried for the kids, I'd be asking why the entire playground isn't fenced in? Do they allow the "normal kids" to play in traffic?
I can hook you up with an acquaintance in Nigeria that's very good with money transfers aquaintenance, let me know.
Try this on a 1U high rackmount server that's fully loaded and needs a new RAID controller battery!
and of course ... without taking the raid out of service!
"rack mount"? most racks don't accept full size towers. I'll try to ignore that minor oversight and press on....
So he had to plug in the cables for the hard drive, but not install the hard drive itself, that was already installed for him?
Heck the motherboard was already installed and most of the wiring attached. Over 75% of the work was already done for him. This whole thing was a joke.
