Very exciting until you see that the results have not been verified in any way.

If the claim is true, I would be very interested in reading how it was accomplished and what were the conditions. I would be particularly interested in finding out if the heat was contained or if energy was being continually driven into the system.

Claims are just that until verified and the apparatus and results are published.

I've been on /. for 20 years (gasp). I haven't seen a lot of difference in the posters.

- There are amazing individuals that provide interesting and detailed insight into issues.
- There are great technical resources and posts by people who truly understand the issues, solutions and how to address them.
- There are a few genuinely funny and clever people.
And, for any given story, 25%+ of the posts are from assholes or good people who, for some reason, post without reading/thinking, believe they have some god-given insight into the issue or are generally having a brain cramp at that particular instant (I think everyone falls into this latter category). That number doesn't seem to have changed over the years.

I don't see that changing and it's really up to everybody to learn how to sort out the bullshit and figure out who are just stupidly angry and who are just plain stupid. In either case, you have to know how to ignore them.

Agreed with everything you said up until the point of "It will be easier and safer..."

I don't know how familiar you are with airport operations but adding additional equipment on the tarmac to the runway adds considerable complexity to aircraft movements which have to be tracked and controlled by the tower. This added complexity has a potential impact on safety as having tugs moving around (manned or autonomous) means that their needs to be new procedures in making sure they don't move in front (or behind in the case of aircraft which aren't compatible with the tugs) aircraft as well as being able to avoid the humans which need to be on the tarmac in any case (ie guiding a plane into and out of a jetway).

There really is a lot of merit of giving the aircraft the ability to taxi on its own without the main engines running.

While the idea of using a fuel-cell powered electric motor to drive the aircraft to the end of the run way before powering up the engines is a bit out there, there are a number of companies that are looking into a providing motors that fit into the landing wheel hubs (I know of at least one such company providing nose wheel motors for taxying for the B737 and A320 -

Apparently it does make a lot of sense to do this in terms of fuel savings. I'm not sure if a fuel cell improves on the process that much as liquid hydrogen and oxygen would have to be brought to the flight line on a regular basis.

I think this article is a way for EasyJet to get free publicity.

Comment Re:Make sure Windows 10 does what you need it to d (Score 1) 581

With code development and debugging, it's not unusual for me to use up 30 com ports (don't forget that each pairing allocates two ports at a time) in a day with it sometimes going as high as 50.

I *think* 255 is the limit in terms of com ports - at least that's where Windows 7 & 8 upchucked when I was doing the code development.

I've got some tricks to delete the allocated ports that I can share with people on Windows 7 & 8 if there's interest.

Actually, I'm not mucking around with com ports.

BT SPP has com ports allocated as a matter of course. For my product, I communicate with the product directly using RFCOMM so no muss, no fuss.

The issue is that when the device is no longer paired with the Windows PC, it does not de-allocate the com ports (this is not a problem with Macs or Linux) and with previous versions of Windows, they can be de-allocated (it's a bit of a cumbersome procedure, but it does the trick) but the process doesn't work with Windows 10.

Comment Make sure Windows 10 does what you need it to do.. (Score 5, Interesting) 581

Just in case you're looking for another reason not to switch.

I put this conversation up as a discussion topic here on /. -

Com port management has never been great in Windows and in Win 10, if you are doing device development work or working with different devices which allocate com ports, you may find yourself running out of them and/or applications no longer working because the allocated port number is higher than the range the application handles.

Very disappointing non-response by Microsoft and their employees.

Comment Could be very interesting technology (Score 0) 262

I'm guessing that the motor and battery installed in the bike are similar to a hybrid system in a car - the battery is charged when there is surplus energy available (ie when normally braking) and then energy is released to the motor when it is required for high energy applications (going up hill, passing, starting up).

Ideally, motor and battery operation would be invisible to the rider; when brakes are applied, a computer determines whether or not to charge the battery and a strain gauge on the pedals determines whether or not power is released to the motor. This technology could be very helpful for traditional bikes and people doing recreational riding on the streets or in the country, evening out the workload and making stopping and starting less of a chore.

If somebody decides to take this note and use it as a basis of crowd-sourcing campaign, please remember where the idea came from; my royalty rates are very reasonable.
