I wanted a recumbent for years (long wheel base) but because of their low production, they tend to be more expensive, are also heavier, and most look funny.
I ride a heavy mountain bike on my 10km , 25 minute commute. Straight line speed isn't the issue. Situational awareness is. It helps that I am 1.93 metres tall so my eye level on the bike is higher than it is in my van.
In a recumbent I would always feel like am about to go under something. Not a good idea.
If I lived somewhere I could ride 50km to work on a straight well paved traffic free road then a recumbent would make sense, but I am not aware of any such place.
Perhaps there should be recumbent road or track races.
doesn't it make sense that you stay inside finder?
From the users POV the two finder windows are different things. The apparent fact that they are both managed by the same application is feature of the implementation which the user should not have to understand.
I can't believe this guy is the President pro Tempore of the senate (third in line of presidential succession).
There are places in my country where it it is a big advantage for a politician to appear to have a funny name, funny voice or minor mental imparement. Any one of these things are worth votes, and votes are worth money.
God knows the Big Mac doesn't look good unless it is on TV, so do you think they wil give you the real smell?
There was an outcry here recently when an advertiser proposed modifying the advertising signs on bus stops to smell like the alcoholic drinks they were advertising.
Smell is a much more intrusive medium than sound or vision. Advertising alcohol or tobacco (if such were legal here) by smell would definitely be wrong. IMO.
Just stop being a bunch of cheap a-holes and BUY music that you like.
I rip my own CDs. Mostly because I like the convenience of listening to them on my laptop. Even here in Australia that is now legal, though it has always been tolerated.
Freedb just gives me track, artist and album names.
Wouldn't the wingspans needed to support even a light payload with flapping wings be too large for the cellophane wing to even support it's own weight?
Thats correct, though people may develop lightweight payloads as well. Here in Melbourne a bunch of peoople used to (and perhaps still do) fly model airplanes in the domed reading room of the state library. This is a really big room with still air. The planes are made of small amounts of balsa and a sheet made by dripping a plastic compound onto the surface of bath of water. They were powered by a rubber band.
One of these planes would fly slowly to the roof over about five minutes and glide slowly to the floor. They flew at (I suppose 10 or 20 cm/s). One day I witnessed a disaster when the airconditioning got turned on by accident and the entire fleet got caught in a scale hurricane.
My garmin GPS lets me assign symbols (boat, shop, phone, etc) to waypoints. The symbol for my workplace is a skull and crossbones. Better not let my boss find out.
Apollo: 12 missions, 2 (Apollo 1&13) major failures (17%), 3 out 36 dead (8%)
Shuttle: 114 missions, 2 major failures (2%), 14 out of 683 dead (2%)
Well OK but you have to consider how the system would have evolved if they had continued flying it after skylab. In general modular systems are easier to upgrade and the well defined interfaces of the apollo system made it possible to upgrade or repair a module without any impact on the rest of the system.
Its just not so easy to upgrade part of the the shuttle stack without risking regression in another part of the system.
The space suits were only designed for operation on the moon, and could never be use while operating the spacecraft.
The command module pilot had an identical suit (without a PLSS) and could operate inside the CM using the CM oxygen supply through hoses. The apollo pressure suit helmets had a valve near the chin which you could push in with the tip of the water gun (in either the LM or CM) to squirt water into your mouth. The idea was that if the CM depressurised the entire crew could return to earth in the suits.
On at least one flight (A16) the CM pilot did an EVA during the flight back to earth using the oxygen purge pack from one of the suits used on the moon. This is a simple gas bottle which provided a backup supply on the lunar surface. During the flight back it was used for a one hour EVA to recover a film pack from the service module.
I am sure they could have flown back in the suits though they would have relied on O2 from the CM. If the apollo 13 CM had depressurised after the accident two of the crew could have hooked up to the oxygen supply from the LM.
It was a beautiful system. It worked so well that Gene Cernan flew the entire apollo 17 landing and takeoff solo. His LMP couldn't fly at all. It was a shame to stop using it just when they got it working so well.
I think we have to accept that, in space flight, humans are not safe
Humans were safer flying apollo. The full apollo stack had three totally independent pressurised environments (CM, LM and pressure suits). Even the pressure suits had two independent air and cooling systems. The heat shield was only exposed immediately before use and by design it was a lot stronger than the shuttle TPS.
It was a bloody good system. Comparable in reliability to the life support systems used in scuba diving. And it had heaps of redundancy. Even in the near disaster of apollo 13 I can think of half a dozen things which the crew might have tried if their work arounds failed.
The shuttle has a bad architecture, and current efforts at fixing it are working against the original design.
The last I heard the landing gear release was a simple manual switch with no connection to the flight control system. TFA describes the new cable as a "Data Cable" so there must also be a new connection between a computer system and the landing gear switch.
Its strange that this was not mentioned in the article. Perhaps this change was made earlier?
Oh and BTW I am still reading the apollo 17 ALSJ and much is made of the exploding foam incidents on apollo 16 and 17. The stuff was literally rocketing up into the sky around the LM during both missions. You would think that somebody would think (foam == bad) as a part of the lessons learnt from apollo. Drilling holes in the stuff is clearly not enough.
With the help of Chen and Ying Tsui, another engineering professor, the initial massive handheld device was shrunk to fit inside a person's mouth.
But they had something like this working in the late 1990s so for part of the last seven years they have been mucking around making a minature version of their machine. A proper engineering job would have taken six months, max, and they could have kept working on the science.
Sorry to bitch about this but I see too much improvisation going on and not enough forethought.
Taking full advantage of the processing power that those multicore architectures potentially make available requires operating systems and development tools that don't exist largely today
Normally when you go to design something you say "what do I need, and what resources are required?". They are saying "what toys are available to us to play with?"
I would like to see more of a move towards pervasive distributed computing. Being able to have the full benefit of a mobile computer without carrying more than the equivalent of a username/password combination.
Have you heard the legend of the Black Dac? It is seen on rare occasions in remote parts of Australia, travelling more or less at tree top level in places where you could reasonable expect not to be seen at all.
Given the spread of suborbital spacecraft, isn't now a good time to take a fresh look at the rotavator idea?
Without a really good heavy lift system the rotavator won't get started at all. The best prospect was the Shuttle ET based big dumb booster, but no more ET's are going to be built now.
Perhaps somebody can come up with a plan to use all those shuttle main engines which will be left at the end of the Shuttle program.
Don't confuse communism the theory with the dictatorships the claim to be communist. Communism as a theory disclaims most if not all personal property rights, but it has nothing to do with Murder and Censorship, any more than Capitalism has to do with monitoring bank records and tapping phone calls.
Many of the modern, ever-so-nice university based communists who live in my city will tell you that their ideal society can not be achieved through democracy. People have to "take their word" that their way is best.
From what I can see, dictatorship is deeply embedded in their way of thinking.
This is actually one of the main reasons why Cellphones are not usable on Planes
But what about hills and tall buildings? For example in the Melbourne CBD there are micro cells in just about every block. I can still go up to the rialto observation tower and use my GSM phone even though I must have line of sight to a couple of dozen antennas.
Are they just exporting from Word but, before exporting, "blocking it out" in Word? If so, how? Are they putting black blocks over text, or setting attributes of the relevent text? If these are the wrong techniques, what can be done to make the right techniques obvious (and the wrongness of these techniques equally obvious)?
Not directly related to your post but I just want to say something about this peer review process we have where I work. We started with a form on paper. You write comments and put a tick against comments where appropriate. There is a word document which you print out to make a form.
Now the process is 100% electronic. We use exactly the same word document. The process says you have to find the tick symbol in word and type it in the appropriate box.
I am the only person there who has a problem with this. Where did the tick come from? From a pen. Why do we have to use it? Because it has always been done that way. Why can't you just type Yes or Y? Because you needed to use a tick on paper.
Sometimes things just evolve. Crap results all the time. My wife employs a draftsman to work on her construction projects. He exports autocad to pdf and tells me that this is so nobody can change his name in the plan to their name. Users have these funny beliefs about their tools. Sometimes it is hard to convince them that they are wrong.
a twisted part of me is still interested to see what would have happened to him should he have been struck!
At high school one student in my class charged himself up on a van degraff generator. I suggested he touch a tap. I was pretty sure what would happen if he touched a really good earth and I wasn't disapointed.
The whole point of the open AP is to encourage people to hang around in the shop or the area around it. The smart thing would be to send somebody out with a free cup of coffee and get him hooked.
I must have read that one 1024 times when by son was between the ages of 0 and 2 years but I can't remember anything about the US constitution or computer games in there:)

How long will it take to recover a 7 byte key, given that the database is loaded with known words (lots of johns, bobs and jacks)?
Thats 3.4E38 combinations to try. But you can copy and return the database before you crack it.

Painted entirely black with no ID, or course.
