More so, there are ISPs that purposely allow this.
So if all ISPs at every hop of the net does active blocking it would be good. E.g. if you get a packet for Y from X and X is on a block list... reject the packet. If there are 10 hops between you and the attacker 10 of them have to "not do filtering" before you see the attack.
Essentially there is vested interest in ISPs todo this. They use less bandwidth which keeps their legit customers happy.
All they have todo is load balance the packet filtering on the out going edge(s) of their network.
I'm not saying you *can't* use a laptop on a flight. I'm saying it's not worth the hassle of getting it out of the bag/case, doing work, being interrupted by the beverage/food/peeps, etc...
The way I found to travel that makes it peaceful is to just space out. Get comfy, put seat belt on and just vege. Mind shuts off, flight seems shorter.
Now if there was more room and an AC outlet... I'd be all over the using the laptop...
Doesn't help that I have a Presario 2100 which isn't exactly a "small" laptop [15" screen to start with]. So opening that on the average tray is a challenge in coach.
um, a mouse weighs all of like 100g at most... I throw mine in my knapsack with my power adapter [which weighs ~400g]. WOW! THATS HEAVY!!!
Plus I'm not a noob and can get along with the keyboard only for 90% of what I do with a computer anyways. Try not using a mickey-mouse operating system and you'll see what a real userland toolset can get you.
Try being 180cm tall or so and having the jerk infront of you "insist" on moving the seat back. Of course I then "insist" on digging my knee into the middle of their back.
And by "insist" I mean "laws of physics dictate this". As much as people like to think I'm a jerk for that I can't grow shorter on the plane so you can lean back over my knees [e.g. my space].
Honestly I don't understand why the seats recline at all. Not like there is actually enough space for it anyways. Might as well just be fixed position and get over it.
As for using a laptop on a plane I never saw the point. On flights 2 hrs you're up and down pretty fast and on longer flights the battery won't last.
So chances are if you're rushing todo work on a 2hr flight to a clients you're not prepared anyways. And otherwise you're laptop won't last the flight so there's no point.
Here's a tip... don't bother using your laptop on a plane or in a restaurant.
ENJOY YOUR LIFE.
I mean I use my laptop professionally and the only time I "really need" to work at it [and not just boot it up to get a number or two] is when I'm at an office of some sort.
When I fly I just relax and enjoy the trip. Bring my gameboy/some cds and enjoy it.
dude, by a 10$ optical mouse and get over yourself.
I'd rather use a real mouse than ANYTHING put in a laptop because it's just simpler. But touchpads aren't really that hard to use. They are annoying if you rest on it by accident when typing but other than that they're not a mystery.
My experience has been on the P4 that "regmove" is a broken optimizer. Specially coupled with the profiler I haven't seen much that is faster with it enabled.
But yes, your right that the actual algorithms will be sensitive to different options.
At the very least you should have done profiled builds though. that's where recent GCCs start to shine [specially on the branch sensitive P4].

Not always. Usually Intel's CC produces faster code except when you give it code [LibTomMath] that it can't efficiently optimize.
Also as he hates to have pointed out his options aren't always optimal.
Quite a few applications are faster with 3.4.3 on a P4 with "-fno-regmove" as well as -O3. My AES for instance goes down from >500 cycles/block to 380 cycles/block on my Prescott P4 with this switch.
380 cycles/block is faster than Intel CC v8.0 with "-O3 -xP -ip" by about 30 cycles/block.
Also the guy probably didn't try profiling. I can drop a fair chunk of cycles in doing ECC point multiplies on my P4 with GCC by doing a profiled build system....
Hard disk write cycles and flash cycles are vastly different.
iirc. the average disk is rated for 10^10 - 10^11 [taken from Seagates average one bit error per 10^14 bits read/written] re-writes per sector while the best flash is around 10^5 - 10^6 [Intel strataflash].
Usually in a modern hard drive the motor will die before the platter becomes unusable.
Inferiority complex? If anything what canadians have that sucks is apathy. We bitch at you americans but then share the same faults and don't fix it...
As for NHL, I personally hate pro hockey [and most sports that don't involve crashes or fire]. It's a scam and not worth the time and money.
I did get a replacement on my own. Hence the $90 for the 40GB drive...
The history went
1. Drive makes clicking noises 2. Tom sends it to Futureshop to get serviced 3. 56 days later I get laptop back 4. Laptop was not fixed, still clicks 5. Several months later it totally dies 6. Tom goes to local shop and buys replacement drive for $90.
Essentially the stores/manufacturers ALREADY rape us seven ways from sunday. This combo drive is just another way to potentially lock people down.
Yeah... to be used for something called a ***CACHE***.
If you had 10GB of memory in a Linux/BSD box you'd get this "boost" too...
As for saving costs by lowering failure... let's hope they don't use cheap flash controllers. Of all the flash based mp3 players I've had [usually got for free with a purchase] most of them fail on a lengthy write or two...
More so let's hope we can still replace this hd+flash combo with a coventional HD.
I know for my Presario laptop [Compaq 2100CA] the replacement HD [Hitachi 60GB] is ==>$710 CAD== while a faster Samsung 40GB is $90...
So what i'm trying to say is... less ass rapage please.
You can do the same with USB and RS232 [iirc] and Parallel by sinking off a status bit or two (limited to like 25mA though).
Back in the day I've seen things like sound cards working on game ports, serial or parallel. People used what they had available;-)
The big change in IEEE1934 and USB is that the power draw is actually standard [e.g. 500mAh for USB] and not just "common".
My Creative Micro-Zen player charges either off an AC adapter or a USB connection. It uses one connection though on the player [mini-USB] to save space. Of course the AC adapter can output 1Ah instead of the 500mAh the USB connection can...
We already have PoU [Power over USB] which was a rehash of PoS [power over serial/parallel] etc...
I think it's good that we can use something like an already existing cat-5 network to power a computer though..
In my case my USB powered 3-port cat-5 switch was handy when I was in France last as a quick-and-dirty means to a network. Can get ~50Mbit/s off it which isn't bad for 2.5 watts.
True, but keep in mind the shuttles were made in the 80s based on the designs/technology of the 70s...
At least today we have strong/lighter materials/computers/stuff that would reduce the cost of missions (less stuff/weight == less fuel == less money) and also make the craft stronger as a whole.
I mean seriously, how do you plan on gaming in space on a 6502 or whatever they have up there?
This is like saying "cancer rates are up compared to 1965"... I say "medicine is detecting more than in 1965".
If you think the early flights were "safer" you're most likely sadly mistaken. They just didn't know about all the problems that could go wrong or had ways of addressing them.
Keep in mind the driving force was to beat the ruskies to the moon. So at all costs.
Though I agree. The shuttles are outdated and there are likely cheaper/safer ways to accomplish the same goal using technology... from THIS DECADE!
This sounds all good and all but totally beside the point.
You can fill an iPod with legit music [e.g. your own] or with itunes or with... Who are they to demand you pay them money because you might, maybe, per chance, pirate the music?
This is EXACTLY like the levies/taxes on CD-R/DVD-R. I use mine to burn shoutcast'ed techno and backup my software [that **I** write]. Why should I pay a levy going to some major corporation so they can continue the downward spiral of talent that is the music industry?
And where does it stop?
Ok tax the media, you need some where to store it.
Tax the headphones? You need to listen to it.
Tax the batteries? You need to power it.
Oh, hell let's tax metal and plastics!
It was delivered on trucks, let's tax them.
And the trucks had fuel, let's tax that.
Then those people who drove the truck need food and housing. Tax that.
So... because the truck driver will likely own a house when he's delivering plastics and metals from time to time which may get turned into ipods components and then maybe delivered to apple to get turned into an ipod which may get delivered to a store near you and you may buy it and then take it home and maybe fill it with pirated music...
We should take at least 20 different other things to make sure nobody leaves untouched by this.
[By "tax" I mean a "levy" beyond what already exists that goes to the RIAA/MPAA].

Congrat for buying into expensive "entertainment" only to be duped by the lying theives that are the home appliance manufuckturers.

Apple has had it share of horror stories too.
The problem isn't so much as Compaq as just plan lazyness and greed [which the industry as a whole shares].
Generally I don't see laptops as such a great buy unless you can try it before paying... specially with all the wintel hardware out there...

if by 50 you mean $564.97 you stupid inbred sister fucking wife beating jackass ... then yes, $50 USD.
duh hahaha you funny you make tired antiquainted joke.
Keep in mind there was a time our dollar was worth more. And also keep in mind the Canadian dollar doesn't go up. The USD goes down!

good call, he can skateboard with them like in RvB.
Tom
Yeah nothing like a 4 month voyage to get there... only to nudge it and fly 4 months home...
The inflight movies better be good otherwise you'll be hella bored!
Tom
Actually there are other benefits too. The 64-bit opcodes require prefix bytes which inturn increases the code size.
So if your algorithm requires 6 registers to be optimal chances are x86_64 won't help at all.
Though usually 6 registers for complicated enough algorithms is a pipedream which is why the x86_64 is a good approach.

Maybe you're using the wrong tools?

What's to stop people from just flooding it with nonsense data?
I mean EVEN if it's "MS signed" or whatever... it's made by a program on your computer.
I say people should reverse engineer the program and make a bot that spews nonsense into it.
