Local Radio

I have taken, again, to listening to local radio. Not local for Kent but local to New Orleans. Yep, that New Orleans. I have a bit of a thing for the New Orleans Saints NFL team and am looking forward to seeing them play next year versus my number two team the Dolphins.

About two years ago I spent time listening to WWL radio station because they broadcast commentary of the Saints’ games. I don’t think they broadcast the games any more but I do find it interesting listening to the other programmes.

I get information about local weather, the quality of the waterways and where the best fishing is. One day I ought to visit the place to get a proper appreciation of what I listen to.

WWL doesn’t broadcast to the UK via TuneIn, but you can find it and get Sonos systems to play it.

Hacking The Car

I recently purchased a new (ish) car. The name of the new vehicle has yet to be decided  but some things did need to be sorted out.

As a safety feature the car beeps an alarm inside the car while in reverse. There aren’t parking sensors so this was purely to warn the driver that you aren’t going to move forward when you depress the go pedal. This beeping was annoying. Googling around soon led to two potential ways to fix it.

If the Prius is pre-2010 then you can use the following method:

Step 1: Depress the brake pedal and hold it there.
Step 2: Press the Start/Stop button to turn on the engine.
Step 3: Push the Odometer button. Push the button on your dash designated Trip/Odometer until “ODO” is displayed on the screen. If it is already displaying this, you will have to cycle through the options to refresh it by pressing the button a total of three times.
Step 4: Press the Start/Stop button. Press the Start/Stop button to turn off the engine of your Prius.
Step 5: Press the Start/Stop button again. With your foot still on the brake, press the Start/Stop button again, and your engine will restart.
Step 6: Push and hold the Odometer button: Push the Trip/Odometer button again and do not release it.
Step 7: Press the park button. While still depressing the Trip/Odometer button, put your Prius in reverse, then immediately push the Park button. Do not release the Trip/Odometer button until this is complete.
Step 8: Push the Trip/Odometer button. Instead of the usual miles traveled on the odometer display, there should be the text “b on.” Push the Trip/Odometer button until the dashboard displays the text “b off.”
Step 9: Press the Start/Stop button again. Press the Start/Stop button again to turn your Prius’ engine off. The reverse beep is now disabled, and you will not hear it again in future trips.

This, I think, is the car equivalent of ctrl-alt-del and using reg-edit and BIOS simultaneously. Now, I can follow instructions, but I wasn’t looking forward to doing this. My car is registered as a “59” but apparently it was a 2010 model as when I looked under the dash there was a OBD2 connector.

It turns out that car manufacturers have standardised the laptop connections to the car and its CPU. This makes sense and it also allows people to connect their own devices and customise or fix or break their own car.

So, I invited a friend over who tries does hack his own car and attempt to improve or fix it. He has a Bluetooth and WiFi connector and I downloaded the Carista app on my phone. After connecting the adaptor to the car and then getting the phone secure connection running the app decided to run some diagnostics tests.

After a short while I was able to pay for a week’s subscription to the Carista app and then able to change the settings.

My car no longer constantly beeps when reversing. It beeps once. Which is good.

I also turned off the seat belt alarm. That would beep constantly too if the driver didn’t have a seat belt on. I always wear my seat belt so this noise isn’t needed either.

Passengers

I’m a sucker for a space film. I love the possibilities, the stars, the tech. It just can look sooooo cool. Quite often these films leave something lacking and aren’t that good. I saw Rogue One and yesterday I watched Earthrise from Amazon Prime.

Because I watched this at home it doesn’t get an Official Parish Rating. So it was with a nerdy interest in tech and space that I went to see Passengers, I wanted to see stunning vistas and how the film-makers had dealt with the ravages of space travel. As is custom I rated this film on IMDB and you should read my guide to the rating system.

It was a perfectly enjoyable film and worth seeing, it had just the right amount of humour but I do feel that the moral issues could be covered more comprehensively in a separate film. This wasn’t a film about morals though. It was a space action thriller and as such it functioned perfectly well. Now, after here, there be dragons.

I had some minor issues with it, but not as many as with this film. So, if we allow hibernation, then we just need to look at the rest of the film to see what liberties they have taken. Mind you, coming out of hibernation looks a lot like CPR, so the travellers were more dead than deep sleeping.

The artificial gravity system seemed to be based mostly on centrifugal force [YES, I KNOW – this is why I don’t allow comments on this site]. The idea that a spinning thing in space would stop spinning when the power is switched off doesn’t quite ring true, momentum and inertia etc. But, then this does allow some pretty good visuals.

Why would little things go wrong if the spaceship was dealing with a big problem in the reactor core? I’m not sure this part of the film rings true. It bothered me a little. But, I was willing to let this go.

The swimming pool. I’m pretty sure that if the gravity was provided by the rotation of the ship then the stars outside the window were rotating the wrong way. I’ll probably have to take a few more looks at this scene but it upset something in my head and I spent a while moving my hands around in the air trying to get rotations correct. The hemispherical window was an awesome idea though.

Only one medi-pod for a ship that size? Bullshit.

When gravity suddenly turns off (?) most things will just stay where they are unless there is an impulse to them. The water in the swimming pool would have rode up the sides of the room when the spinning stopped. The sleeping characters would have moved very slowly if at all as they don’t have any forces acting on them. I refer you to Newton’s First Law Of Motion.

There are other bits and pieces but they are largely inconsequential and do not show off my understanding of sciencey shit. I do think that a film covering the morals of “living murder” would be very interesting if written by someone talented.

Oh, Arcturus. The space ship sling-shots around Arcturus. I don’t have a problem with that per se, but the ship did seem pretty close to the star. It would have fried to a crisp and everyone would have been killed by the intense radiation. While this allowed for pretty visuals [based on the SOHO observations of our own sun] the radiation shielding would need to be metres thick. Arcturus is a pretty darn big star coming in at 25.7 times the diameter of our piddly little star The Sun. It’s also 36.7 ly away and the spaceship in the film had been travelling for 30 years and had just reached 0.5c so the film makers could have done some better sums here I feel although we don’t know if the time measurement is absolute [physicists would laugh at that concept] or relative.

Last thing: The company that owns the starship made x quadrillion profit we are told. I am pretty sure that Aurora [!] then explains that a quadrillion is “a thousand billion”. I may have misheard this but a quadrillion is a million million using the US naming system. Aurora was talking about a trillion which is a LOT less money.

Quadrillion [US] – 10^12
Quadrillion [UK, but not common] – 10^24
