How can they enforce, or even implement no linking outside of kids.us domains? What about IP addresses? What about virtual servers, that share IP addresses?
It might make it easier to filter, but still far from easy. And any kid that knows how to use nslookup (oh, sorry - that's been depricated. Of course I meant dig) can bypass it.

WiFi Triangulation

Triangulation of EM is based on the assumption that the strength of a signal will diminish with the square of the distance from the source, or some other constant function with other signals.
When was the last time you were using wireless (especially through a wall) that had the same range from the access point in any direction?
I can't picture it working in a supermarket, with the metal shelving, compressors for the cold storage, etc. Sure, in a lab it'll work great, but with any kind of range or non-uniform building structures, not a chance.
Every program you listed is geared towards servers and isn't used on most installations (except sendmail).
Instead, try fetchmail, mutt, and mozilla.
The problem is with internet connection speeds.
On XP, and service-packed 2k, there is an automatic updater that check for updates. It's even easier to use than YaST, or RHN, apt-get. The problem is getting people to download hundreds of megabytes of updates per year over a 28.8kbps connection.
There is no easy solution. Consider a cheap update CD that goes out quarterly, except MS and Apple won't let you get those patches from anywhere but their websites.
To do this, Sun has re-used technology that is already part of its high-end servers and storage systems
Oh yeah, These systems are a piece of cake to admin. No one ever installs or has to maintain Veritas file systems, backup, clustering, or any other software because the sun software sucks so much.
So, is this new operating system going to handle change control, log rotations and parsing, access control, etc. so that a secretary could handle it?
Or is it going to automatically call Sun and allow their services department to handle any issues that crop up?
Most of the stuff that was "special" about laptops has been standardized, including power management (APM and ACPI) internal peripherals (mini-pci).
The biggest thing now is to keep in mind which video and audio chipsets are going to be compatible, which is easier to do in the design stage than the support stage later on.
I love my T series thinkpad, and as long as future designs take those chipset issues into consideration, then I'll stick with the thinkpad for a long, long time.
I love my Thinkpad, as it has the best keyboard of any laptop that I tried. I use the built in keyboard enough that I've worn the texturing off half the letters.
There are many support pages and "rings" around the web for thinkpads,and I hope that at least the IBM design teams think about non-MS Operating systems when producing future thinkpads, unlike the TP600 modem debacle.
It'll be a tough one to replace when the time comes.
At 10 times stronger than steel, and with obsolescence for your PC hardware heading your way in about 3 years, just how hard of a hit is this new technology going to have on landfills?
Fine - tax the books, games, movies, etc that I pay for every year.
But, I want it run for profit, and I want a cut of the profits. No Department of Defense Freebies, knock of the senators having any frigging say in what gets researched, swipe my national ID card and give me a cut of the profits based on the copious amounts of sci-fi that I read/watch/play.
BTW - that means TV (sattelite launches) missle shield, possible microwave power futures, whatever.

P2P over HTTP was to bypass firewalls

HTTP's Days Numbered
·
· Score: 2, Insightful
The only reason that all these applications run over HTTP is so that the applications don't have to worry about Firewalls.
Business Network administrators don't want employees downloading music using napster, Real, Quicktime, or WMA. Except for napster, all of those applications run more efficiently over their native protocol than HTTP, but they fall back to HTTP and make it through the firewall when there is an issue.
So, call it like it is - they are just looking for a more efficient way to bypass firewalls.
On the other hand, if a service is explicitly named in their new standard, then it would help administrators. Maybe the next generation firewall would be able to be configured for: OK to HTML, but any RTSP requests get logged and sent to NULL.

Is Hyperchip Hype?
·
· Score: 4, Informative
That makes their product different. With Cisco gear, you have a very, very small number of high speed ports available to you in one chassis (and several of these "capabilities" are eaten up when you go with redundant solutions).
The idea behind Hyperchip, that is a supposedly better implementation than Avichi's that preceeded it, is to have a packet switching backplane that is expandable to multiple bays, as opposed to the tiny boxes such as the cisco 12000. Since it is a common backplane, there are fewer "hops".
The real limit is power. The Avici systems used over 400 amps of three phase power per bay, and (I believe) scaled to 16 bays, each one capable of running over 60 OC-192s at line speed.
Hyperchip's unit looks better.
Right now, their just trying to figure out how to market it, and how they can add services inside the box that you wouldn't get otherwise. Think of all the stuff you would like to do to streams of that size, but just can't. Also, think of what to do with packets that are going to full pipes. At OC-192 speeds, you can't hold on to packets. There isn't enough time to put it in to memory.
PS OC-192 can carry approximately 10 Gb/s. Or, over 1.2GB/s (this isn't ethernet, it's sonet) (but will have 10 Gb ethernet interfaces, but they just can't carry as much)
At 10 Gb/s, a 1600 byte packet (for those ethernet fans out there) is on the wire (going across a fixed point)for 160 nanoseconds.
Some assumptions have been made by me here:
Your company has more than 500 employees
You are developing for internal customers (ie you are in IT developing for the rest of the company)
Windows is the primary platform for users and servers, perhaps supporting some other platforms on the server side as well (this type of company would likely be using Sun or IBM)
The biggest requirement is that there is a dedicated IT resource for (about) every 5 developers.
As far as registry restrictions, that's lame. Probably means that you can't run regedt32, which means you can't do your job. If they want to lock down the registry, do it by permissions to modify the different hives and keys, not by restricting tools.
There are definate benifits to the company if this is done correctly. Code maintainability being the foremost. If there is developer turnover, then using a common toolset is going to greatly benefit the ability for the new programmer to come up to speed on internal development. Also, all developers on a team can benefit from one another's insight on the best tools - demos should still be allowed to be loaded, just by the IT guy that is monitoring all those damned DLLs etc that you don't want to.
Remember, Windows is pretty much the only environment that allows you so much "flexibility", which is also why everyone bitches about it's stability. Developers on *nix and mainframes are much more likely to be using a standardized toolset for corporations.
The other side of the coin: restricting access in a windows environment is a tough job, costs a ton of money, and means that the IT group has to be GOOD. Really good. Otherwise, morale is going to start spiraling downwards because employees are hindered by the change instead of helping.
Neither will detect a successful tap, but inducing an electrostatic charge on the conduit (a la the lamps that you touch anywhere on the base to activate/deactivate) would let monitoring systems know if someone touches the pipe to set off an alarm and shut down communications, but would open you up to an easy DOS.
The second is an OTDR (optical time domain reflectometer) - this will easily detect changes in the fiber layout, and will also tell you exactly where the tap/modification occurred.
Basically, an OTDR sends a pulse of light and looks at the reflection(s) over time. It will show bends, nicks, etc that occur in the fibre.
i.e. if there was a central store that spammers would have to check their address list with before sending unsolicited content. perhaps downloadable with one way encryption, so they wouldn't have to use net resources to check them every time, but at the same time wouldn't be able to skim the list for addresses.
