Has anyone here tried alternate 'simplified' keyboards like DVORAK or the Twiddler chording keyboard? I used a DVORAK extensively in college and during my early hacking days, but when I had to start working on a variety of client machines and when laptops came along I had to switch back to QWERTY as I couldn't switch between the two proficiently. I loved my DVORAK keyboard and typed about 20WPM faster, but was forced into conformity since I found that my "muscle memory" keyboard chording from DVORAK led me to make mistakes on QWERTY even though I understood the layout. I got bad carpal tunnel at one point from working too much on a QWERTY board and almost switched back to DVORAK, but instead I took a vacation then bought a "natural" split keyboard and never had bad RSI again.
For a time I used a twiddler one hand chording keyboard with my wearable computer that I wore daily for a graduate school project. It was a neat one-handed interface, definetely more practical than QWERTY for mobile computing, but once again I fell into conformity when I finished up the project and went back to using a laptop.
The big problem with switching to a new interface is that I only seemed to be able to hold one keyboard layout in my brain. Two caused confusion while typing. Does anyone have experience with being able to work effectively switching between two layouts?

Why put two "huge" space station (huge so they have enough mass they don't push themselves out of orbit)in space, one around Earth & one around Mars, when you can put the drive on the ship? Launch the ship and let it push itself 1/2 way to Mars with the plasma drive, turn around and fire the drive in reverse to break for Mars orbit, then later reverse the process. Why not just use the huge plasma generator as a ship drive?

* IPsec is widely available since Windows 2000. Why isn't it widely deployed/used ? -IPSEC is widely used in v4, but only at an application level since it isn't universally available on all IPv4 device stacks. With IPv6, IPSEC is mandated on all devices. All V6 capable devices must have a minimal level of IPSEC so we can achieve some interoperable, simple to implement security.
"* QoS : solution exist for years, but none is used, why would that change with a new technique ?" We certainly use diffserv today, but it is more expensive and resource intensive to handle each packet seperately, where a flow label could be used for label switching paths similar (but with less overhead) to MPLS.
"* end-to-end : yep, no one ever chat or make phone calls trough a NAT" No one can chat or make phone calls directly through a NAT - you generally must rely on some intermediate service to hook you up E2E. The infrastructure would be far cheaper and reliable without having to be logged in to a service. Wouldn't it be nice to make direct VOIP calls over your ISP's network without also paying some service provider for call setup?
"* Multicast : see QoS, what change for multicast with IPv6 that will enable it in the routers ?" IPv6 lets you generate multicast streams with guaranteed globally unique addresses, in addition to addresses for a node, link, site, or organization. IPv6 makes extensive use of scoped multicast for efficient autoconfiguration and local service discovery. In IPv4 global multicast addresses had to be assigned from IANA while IPv6 has unicast-prefix-based IPv6 multicast addresses so any node can generate a globally routable, unique IPv6 multicast address based on it's unicast address assignement. The bottom line-this makes multicast cheaper and easier to use...
"* Simplifier headers : AFAIK, backbone routers aren't processing the IP headers." A: Routing is done before entry in the backbone and labels are affixed according to the router's decision - then label switching is done in most high capacity optical backbones. Switching currently requires the extra overhead of adding MPLS labels since IPv4 headers don't support high-speed routing well or switching at all. The IPv6 flow label allows for switching of IP labels, and taking out the checksum allow for very high speed routing.
"* Adreses/routing table : I tought that route summarization is also there for v4 ?" - - You refer to CIDR/supernetting, however for CIDR aggregation to work, the subnets involved must be contiguous (numerically adjacent) in the address space. The problem is that v4 address allocation was not always done contigously and is still a bit of a mess. Of course you could always call back all the v4 address space and reassign it properly (yeah right!) or move on to a fresh start (IPv6). IPv6 address space is large enough to leave large gaps between allocations so an entity can be assigned more space later if needed. This is called sparse allocation. Also, renumbering networks to achieve greater aggregation, if it became necessary, is far easier in IPv6 network auto-renembering.
"What can I do with IPv6 I can't do with IPv4" How about: -Efficient low-level autoconfiguration and reconfiguration based on multicast messaging- great for P2P nets and simplified administration! -Really anonymous peer-to-peer applications using cypto-generated IPv6 addresses from RFC 3041 and a true E2E network (No NAT!) -Information distribution with global geographic multicast? -Information distribution via communities of interest based on multicast -Univeral host based security being built on IPSEC to prevent insider attacks and create a defense-in-depth -Mobile IP that actuall can work everywhere and is efficient -Flow label switching eliminating the need for adding extra labels to switched networks... -Did I mention no NAT?

You obviously are still thinking "In the IPv4 Box" and don't realize how much the current NAT model is holding back the Internet evolution - that's why IETF engineers are behind the IPv6 evolution.
*IPSEC-not deployed widely and not available in IPv4 stacks below a few application-specific instances. With IPv6 mandated universal IPSEC we could create firewall/VPNs at the host level, and create a defense in depth against insider and outsider attacks.
*QOS-Needed to expand VOIP telephony and make it really useful. Also needed to converge multimedia onto cheaper packet switched networks. We don't have a way to do integrated services efficiently in IPv4 - thats why the IPv6 flow label was invented (read draft 6LSA)
*E2E connectivity actually enables all the P2P apps we currently don't have because we have to use central servers to connect. NAT typically breaks E2E like IP telephony, chat, etc...
*multicast - if we had IPv6 multicast address space and E2E connectivity we would have had extensive use of multicast already. Right now it is impractical to deploy multicast for multimedia distribution.
*Simplified headers = cheaper routers especially on high speede backbones where processing the checksum in IPv4 is resource expensive.
*Gajillions:) of addresses = really small routing tables if you RTFM and understand route summarization and the IPv6 header.
If you need tech-heavy, read the RFCs and THINK about what you could do with the new v6 paradigm

The article was pretty lame, tech-lite piece which just referring to IPv6 as a "renumbering scheme." IPv6 is far more than a "renumbering scheme", it adds built in security mechanisms, better support for QOS via the flow label, route summarization, true end-to-end network connectivity, expanded multicast space, scoped multicast, simplified headers for faster processing, etc... Oh, and it has gajillions of addresses!

The article wasn't far off on mileage for my Civic Hybrid. We get about 37-42 MPG in the city, the range depends on if we run the AC/defroster or not. We drive pretty conservatively - not making "jackrabbit starts" from the light and trying to coast up to stops to charge the battery. On the highway we get about 45mpg - about the advertised mpg. On the rare occasion we go on the highway and get stuck in traffic jams, with "stop and go" traffic, the engine doesn't stay cut off as you creep along and you get mileage in the low 30s.
Going the military route will also help you to land jobs in the defense industry. Jobs that will not be outsourced to India any time soon. Just make sure not to mention of you smoked (but didn't inhale) when you apply for your security clearance.;)

Actually the problem is known as an assumption error in modeling. It's a problem with the basic assumption used to represent the real system in modeling. Those assumptions should be tested during model validation but often are skipped. Software bugs are verification errors. It sounds like the model programmer built a perfect model based on the inputs he was given, but a basic assumption (that large numbers of pedestrians will use the bridge) was not included.
