No humans required

Proposals are being looked at to automate aircraft over our skies. Personally, I think the time has come to look at more automation and the circumstances surrounding our airspace use is a nice tightly regulated environment which could very well be the ideal place to implement this.

With a few caveats of course.

After all we have had automated landing systems for a while now and most modern aircraft can take off, fly to their destination and land all while the pilots are chatting up the cabin staff. Pilots like to take control for takeoff and landing but they do not have to and in reality they are only there if something goes wrong that the simplistic controls cannot handle. I don’t see that changing because, unlike some people, I can’t see our IT developers becoming omnipotent any time soon.

When I started in competers [abo £&3% ears ][Corrupted sector] ago I remember reading an article by a guy in the US. In it he was told that next time he was on a plane a message would come over the tannoy saying that this was to be the worlds first fully automated flight and there was no human pilot on board. Knowing what he knew about software, how would he feel?. His reply was that he wouldn’t be bothered at all because if his pupils had written the software it wouldn’t even manage to start the engines. I can’t remember the guys name but he wrote articles that made me think. This one made me think that it is amazing how many people write software that require others to risk their lives but the software writer themselves don’t have any risk beyond a reprimand if it goes wrong. Buggy programs are a norm not an exception regardless of the development methods and many man hours go into testing, code reading and tweaking methodologies to reduce the number of bugs. Very complex programs always have bugs in them. Just look at how many fixes we get for even basic things like word processing.

So, bearing in mind we cannot envisage everything that could happen to flights I don’t see how we would completely automate flights that required no pilots at all. However, having the comms bandwidth we have now and the improvement in software development methodologies we should be able to write software to fully automate aircraft from taxi and takeoff to landing and taxi based on instructions transmitted to the aircraft from Air Traffic Control. We can automate the aircraft to keep certain distances away from other aircraft and fly within clearly defined parameters setting alarms if these are exceeded. Plus we can have a group of pilots sitting at a ATC somewhere who can take control of the aircraft remotely at key moments and in the event of an issue occuring outside the softwares capabilities. This would also enable the software to be simpler and thus tighter and less buggy.

In reality this would mean a plane would be fully automated with human supervision at all stages and with air travel so heavily controlled anyway by remote controllers we could roll it out easily in stages, test aircraft, small carriers, all cargo and, when everyone was happy, phase it into passenger aircraft. Countries without automated landing gear could use the remote pilots.

Sounds good, but why is it being looked at now in the middle of our finanicial woes?

As suspected, it isn’t all sweetness and light. Air travel is already stricly controlled from the ground due to rules and regulations. The only real benefits from replacing the pilots is that they will reduce the costs for the airlines, why would the FAA care about that? and that it will stop nutter pilots and hijacked planes going amok. Now that I can understand. The plan is to control the skies. All under the guise of stopping terrorism I would guess.

Only problem with that though is that there are a million and one private aircraft and smaller transports that fly the skies every day under Visual Flight Rules and with no ATC or government employee knowing anything about them. As well as terrorists we have drug dealers, people smugglers, general smugglers such as tobacco and even people just having fun, the b4$4rd$. All these need to be controlled and this is the best way to do it. Under the guise cloak of terrorism they can automate the skies and then insist every aircraft be fitted with control software and join the ATC group or at the minimum a transponder. Taxes and fees to be paid as required and flying isn’t even a right but a privilege us plebs have if we can afford it.

Oh Joy. Another step towards a Russian utopia.

A cold, dark and miserable future awaits

When you build a prototype or the first of it’s kind you choose the best materials, you ensure you choose the best location and you ensure that the work put into it is the best you can do. You want a showcase, a prize that you can show to all and say this is what we can do. You are building a beacon of the future.

So what about our great Green Renewables future then?

via Devils Kitchen (and other sites) we have the results from the government new first “green” island, the Isle of Eigg. Only 95 people and an island they could put anything they wanted on and they have to fall back to diesel power in the middle of summer for the electrickery for their heating, cooking and hot water. Sure you don’t need as much at this time but if you can’t even provide it in a low demand time in a one horse town then how can you expect to when demand is high in the inner cities? Read the story here. Isn’t this weather going to be the norm in a few years?

Darkness, cold and misery coming to a city near you soon.

Shooting yourself in the foot

In a previous post I pointed out that we had taken a step towards protecting Earth from errant asteroids with the use of the Pan-STARRS telescope.

Now it appears that, for security reasons, we are limitings it’s scans by 24%.

Does anyone else see the stupidity of that? It will take much longer for us to identify threats and for no real reason. Anyone who has some readily available equipment can set up a much smaller set up to detect these satellites already. You would think that they would simply restrict the information released from the project. I have no doubt they are already doing that. Wouldn’t want the plebs or johnny foreigner to know about an incoming asteroid before the politicians do. It would be simple to allow the system to see what it can and then exclude the *cough* secret satellites. Must be much simpler than all the coding involved to smudge them.

Idiots.

FBI fails to crack TrueCrypt encryption.

Encryption saved the day for Dantas, a Brazilian banker, who had his computers seized by Plod in 2008. After nearly two years and help from the FBI the encryption remained unbroken. It is suspected that he used a 256 AES algorithm under TrueCrypt Disk Encryption. TrueCrypt is a free open source encryption program available for all the major PC operating systems. 256 bits btw is not really very secure and some packages can give 2048 bits or more. Bearing in mind each bit theoretically doubles the complexity you can see Plod have a problem.

I liked the bit that said ‘In the UK, Dantas would be compelled to reveal his passphrase under threat of imprisonment’ You really have to love the stupidity of Plods mentality and the futility of that law. It is true that you have to divulge your passkeys in the UK and it is a powerful incentive for most of us. However as it is another law supposed to be aimed at the big guys it is pretty ineffectual against them and just hits the little guy.

You see if I am a big guy and I decrypt my files for you I can get five to life for many crimes plus confiscated assets but compared to three years for not decrypting them it seems a bargain. That is of course if they can convince someone that it is actually your computer and you know the keys. Hell, If I am rich enough I may even pay someone to bite that bullet for me. Can you see a Terrorist giving over the plans for the next 911 or a pedophile giving over the keys to his collection? Three years is a bargain for them.

Unfortunately, being a small guy I have to give my keys up because three years for hiding my tax evasion is not worth it. So much for clamping down on the big guys but we know in our hearts it was always meant for us. The big guys are too much hassle.

Anyway, Disk Encryption is a tool for you. Get it and use it. Make sure you do it properly though. Follow all the instructions about keys and making sure you keep everything secure and if possible make your disks denyable. If they are not sure they are yours you can’t be expected to know the keys. At the very least the manpower required to attempt to crack these will make them concentrate on the key targets which is unlikely to be you.

Of course, you should also consider steganography. For many of us this would be sufficient and if they can’t prove that there is an encrypted file then they can’t jail you for not providing the keys. Think about it. With home pictures of 10MP, and growing weekly, you can easily hide your income tax evasion details in those and you can even keep them on Flickr, a file service or a blog and not on your own computer.

Isn’t technology wonderful.

A spammy OS

I think I’ll be giving any Windows 7 based phone a miss. Read about MicroSofts ‘ad serving machine’ here.

Self-sustainable underwater worlds

One of the futurustic type biospheres we keep hearing about are underwater ones. Personally, I think I would like to live in one but I think they are impractical for general use. I could be convinced otherwise by looking at some like this though. (Click image)

My view is that we should have these biospheres as scientific research stations and holiday/nature parks but that we should build our homes and factories underground where there is less risk of accidents and natural disasters and temperature and environmental conditions are more stable.

Black Hole Physics makes my head hurt

I know that advanced physics is a very complicated subject. I’m also aware that I’m not even an amateur when it comes to black holes and the physics involved, I’m merely an interested fiddler. I do however, understand the basic physical principles behind many things.

For example, I understand about planets being formed because mass clumps together, I understand that the gravity there can cause it to compress and heat up, I understand black holes being formed because there is somuch mass that the whole thing collapses and compresses to a very small space. I also understand how the gravity well created by a black hole won’t allow anything to escape, even light, and thus we have an event horizon. The line in space past which light can’t escape where before it can.

Now in my simple mind we should be able to lower some sensors on a bit of rope beyond the event horizon and see what is there. Ok, It’ll have to be strong rope but the principle is still the same.

What I don’t understand is how we can change some parameters such as angular velocity and make the event horizon vanish. What sort of energy requirement is that going to take? But isn’t that simply spinning the black hole to reduce it’s gravity anyway? Simply moving the event horizon nearing the singularity itself. Still leaving the singularity shrouded though. And if you made the angular velocity sufficient to remove the event horizon surely it wouldn’t be a black hole then? It’ll just be a large spinning mass on the verge of being a black hole. Better get working on a very long yet stong piece of string then if you want to see beyond the event horizon.

I was particularly impressed with the phrase ‘Getting rid of the event horizon is simply a question of increasing the angular momentum and …..’ A new definition of the word simply I fear.

Watching the skies

Well it seems that someone at least is watching the skies for potential Earth impacts. Say hello to the U.S Air Force funded Pan-STARRS (Panoramic Survey Telescope & Rapid Response System) telescope.

The new Pan-STARRS 1,400 Mpixel telescope is now in operation in Hawaii. It is designed simply to scan the skies every night and identify the orbital trajectory of every object it sees. It can scan an area of the sky as large as 36 full moons in one exposure and a nights worth of data will take 1,000 DVDs to store. It can process one-sixth of the sky each month. Although being funded by the U.S Air Force makes me wonder what they expect to see? Could they be really worried about an alien invasion?

Of course finding these objects is one thing. Dealing with what they find is another especially when we have no idea what could be heading our way. I suppose this is a bit like our medical expertise. We can diagnose many things, curing them is something different. Especially, if what they find is alien craft heading our way.

Remind me what data protection means again to our government

It seems to me that more than enough of our rights have been screwed over on the laughably named War On Terror.

The US seems to be sucking up as much data as it can including our bank account data while the teams of people we pay to pretend they are in data protection are laughably quiet and ineffective. As part of our cost saving excercises we may as well get rid of the lot of them. The are useless.

I think it’s about time the US was told to FUCK OFF and keep it’s nose out of our affairs. We can look ourselves and see if any of our bank accounts are used for terrorists. Personally, I’m getting fed up of the slightest excuse being used to impose more restrictions and monitoring on us.

Enough is enough. The US is losing it’s influence all over the world because of the attitude of it’s leadership. Now is the time to just refuse to comply with their demands. What are they going to do about it?

Free VoIP calls via Google

Found this article on my travels. It’s basically a step by step guide on setting up a SIP phone and interfacing to Google Voice.

The SIP component alone could save you a lot of money and the Google interface could save you a lot of hassle if you use Google a lot. This is the first time I’ve heard of Google Voice. It sounds like Google’s attempt to break into the VoIP market and compete with Skype.

Worth a look.
