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 - http://www.wheeltug.com/).
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.
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.
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.
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.
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.
I suspect that you didn't present a case that would be palatable and, from the CEO's perspective, he probably made the right decision based on the information given.
There was probably a strong "if it ain't broke, don't fix it" (especially with a $500k price tag) mentality that you have to break.
What if you had asked for $50k to set up redundant production servers and networking equipment to ensure the data centre would never go down? This modernized equipment would be demonstrated to work with the existing infrastructure and then when an "accident" happened, you were a hero because you were ready for the eventuality and the CEO can feel like he was being both prudent and forward thinking. Moving forward and dealing with this "accident" and some others that follow, you would have been probably able to get more than $500k in total and everybody would have been happy.
I think the obvious one was Die-Hard and his Hans Gruber is still the best movie villain. He was a great choice for Snape.

We believe it was assembled for her in 1986/87 using the cheapest parts we could find in Toronto. Still running MS-DOS 3.1.
But, it was used basically every day from when we gave it to her until her death last August. We had to replace the monitor with a flat screen and the keyboard was replaced at least twice (thank god for USB to PS2 adapters). (Epson) dot-matrix printer still running tickety-boo and "compatible" ribbons can still be found at Staples.
She used it for letter writing and refused any suggestion that she should get a "new" one.
After landing in Paris, Lindbergh flew the Spirit of St. Louis through various European countries. Then, after it was returned to the US (via steamship), it was flown on a goodwill tour of North and Central America.
My grandfather saw the Spirit of St. Louis after it crossed the Atlantic and always talked about how it was a "real airplane", not something that just did a stunt once.
I guess Musk got an AI demo that scared the bejeezus out of him because I always think about an article I read about the genesis of SpaceX where he sat down for a couple of days with a spreadsheet working at figuring out if there was a business opportunity with a reusable launcher.
That kind of data centric, analytical approach doesn't seem to be taken here - it seems to be more knee-jerk worry than anything else.
Better uses for the $1B? Let's see: - Practical electric propulsion for airliners. - Large scale power storage and distribution systems for EV, wind and tidal (all renewable) energy sources. - Lunar mining, refining and smelting to help create a sustainable industry off earth. - An electric delivery van. - Accelerating the Dragon II development.
All would provide returns which would help mankind, would disrupt entrenched industries and provide a (somewhat risky) ROI for other investors to join in.
One of the things that has frustrated me about SpaceX is it's lack of comprehensive communications about the status of the analysis, what are the corrective actions and what is it's return to launch (and beyond plans).
I just took a look at their website (http://www.spacex.com/) and what do I see? CRS-7 Updates, dated July 20th. Under "Updates", the last entry is July 20th. On twitter, the last time Musk commented on the Falcon issue was July 5th.
The dearth of timely web page updates and information just doesn't fit with a company that wants to build excitement about spaceflight (and their products and approach to spaceflight).
Microsoft's "Critical Update" screwed up my iPhone 5S's update to IOS 9.2 to the point where it almost bricked the phone.
I ended up spending 15 minutes with Apple Support trying to get the phone back using a Mac when... the Mac announced it had an update to El Capitan and Xcode.
Maybe it's time that manufacturers set aside unique days (of the month) for releasing their updates so that they all don't collide?
Sorry, just bitching because I really didn't need to lose an hour on an iPhone update which is normally transparent to me.
I cringed at the sentence "Receive tuning (if it can be called such) was achieved by the precisely cut antenna." which is actually how EVERY radio is tuned; the antenna is a component of the resonant circuit which forms the receiver.
I've read about the bugged seal for years, when I was a kid it was used as an example how how nasty Soviets could never be trusted. It's an interesting story - but honestly, the story of the US embassy built in Moscow in the early 1980s is much more interesting. I knew two people involved with the analysis of the building and it's a fascinating case of hubris. The US felt that they could detect any passive resonant cavity devices using the same techniques they used for "The Thing" and, more importantly, for active radios, they could detect them by a non-linear junction detector (https://en.wikipedia.org/wiki/Nonlinear_junction_detector) which finds the P-N junctions of diodes and transistors.
The Soviets, knowing this, simply dumped a bunch of diodes in the concrete used for the building meaning that everywhere in the building, the diodes would be found and could not be distinguished from any other electronic devices in the building making the search for bugging devices impossible.
My friends spent several months chipping at the concrete walls of the embassy and never found any listening devices, just diodes which were labouriously separated from the concrete. It's interesting to see articles of the day (http://www.nytimes.com/1988/11/15/world/the-bugged-embassy-case-what-went-wrong.html?pagewanted=all & http://articles.latimes.com/19...) claiming that listening devices were found in the building but what I was told was that there were a few pieces of rebar which were not properly installed and about $500 worth of diodes mixed into the concrete. The claims of listening devices are most likely exaggerated to lessen the embarrassment that the Soviets had pulled over such a big coup over on the US for what amounts to petty cash.
My grade 10 math was exactly the same: Geometry and Proofs. I always felt it helped me with the thought process for programming.
My high school had a grade 11 course in programming (cards going into an IBM 1150) and the a language called "MLS" ("Machine Language Simulator"). The teacher was an alcoholic who really didn't care whether or not you did anything, so most of the other students were there as an easy credit and you could get banners printed by filling out your cards as each line making a line of the banner.
I think I was the only student that took things seriously and by the end of the course I was able to demonstrate multiplication and division (the language only had addition, subtraction and instruction skip on flag values for conditional operation). I figured it out how to program the machine from the documentation.
My mark for doing more than the rest of the class combined? 51% and I've never been sure why (although I have my theories).
Slashdot Mirror
Seriously?
I'm guessing that somebody went out of their way to look for something like this and then was "shocked! shocked!" to find them.

Thank you for the informative post; I always wondered about stars and how they used up the hydrogen fuel within them.

Anybody have any links?
