Keep your hands on the f*cking wheel! New Tesla update like being taught to drive by your dad

ridley

Re: Auto-crash-pilot

The problem is that in this situation there are no sensors on the Tesla/Volvo etc that can "see" the stationary car, so it will not apply the brakes.

The radar is used to detect other moving objects, not stationary ones. The reason for this is that the radar cannot tell overhead obstacles from those in the road so if it stopped for every stationary object it would be stopping for overhanging trees, overhead street signs etc.

It might be different if they used LIDAR but they don't.

Re: I wonder...

I remember walking along Spurn head* one day when a Lightning went past very close to the spit at really quite high speed.

It was rather loud and very unexpected but what was most impressive was that I swear I looked DOWN into the cockpit.

*Spurn head is a sand spit sticking out miles into the Humber estuary, technically the head is the end of the Spurn. The top of it is between 6-9m above sea level.

Re: Reminds me of JAFO

I cannot remember which book it was but certainly a autobi graph of one of the WW2 pilots, maybe winkle brown, but the were assigned as observers to the naval bombardment on D-Day flying above the beaches watching and calling in adjustments to the ships fire,

All was going well, though the flying tricky as the air was choppy.

A sudden realisation occurred, when a "shadow" passed by, about WHY the air was choppy he decided to adjust his altitude, sharpish.

Nothing like several battleships broadsides passing close by to really wake you up.

Re: Staff don’t care about access to the computers

I cannot help remembering a book I read on the early days of the SAS.

In the beginning they were up to no good in northen Africa, where there was only one use able road the one along the coast. But the SAS wanted to work behin enemy line so had to go into the almost impassible desert to avoid the road.

However after a few operations they realised it was much quicker to wait until a Germany convoy was passing and join it in their British marked trucks, drive with them until they got were they wanted to go and pull off the road and out of the convoy. They didn't even bother with Germany uniforms.

'Autopilot' Tesla crashed into our parked patrol car, say SoCal cops

ridley

There could be many reasons why someone knocks over and kills a cyclist, not all of them being the car drivers fault.

So without more information it is impossible to say whether this was far too lenient or a travesty of justice that they received any sentence at all.

Re: Hmm

I believe it does.

Well sort of, it warns the driver that it does not understand what is going on buzzes and shakes the wheel, instructing the driver to take over. Very similar to a commercial plane's autopilot. I believe it will not allow it to be engaged until it is "happy" it can track the surroundings.

In a similar way to a plane's autopilot the driver should be aware of what is going on around them at all times and they should be prepared to take over at any time.

Would you be OK with the Pilot and Co-Pilot of a plane both coming back into the cabin for a meal* at the same time, or would you expect them to be monitoring the situation at all times?

*esp if fish is on the menu.

Re: at least they turned up...

In the late 90's i was running my own business and one day i needed to pay in at the bank. Parked in the bank car park, went into the bank, payed in went out and thought i need some fags. So i wandered off down the street to the newsagents.

When i came back, plod was everywhere and especially around my car. They were very interested in having a chat with me, very interested.

I was held for ages before being told anything about what was going on.

It turned out that up the road a jewellers had been robbed and the owner sadly killed.

Now where did i come in? The robbers had been seen in a high performance muscle car. I drove a TR7...

My PC is on fire! Can you back it up really, really fast?

I can never understand our Schools evacuation procedure.

1) If it is a fire alarm leave everything where it is and exit via the nearest exit etc, all very sensible.

2) If it is a bomb alarm TAKE ALL YOUR BAGS WITH YOU exit and gather together at the muster station. WTF

I have questioned the sense in this but have been told something along the line of it would take too long checking all the bags in a school.

What!

Re: I recall even my mum (a bit like Dilmom) telling me a fire story

First week of GTP teacher training ie training by teaching.

Scheme of work said to show students that phosphorous didn't conduct electricity by clipping leads to each end of a small rod of phosphorous and showing no current flowed. Thought, strange but must be OK as in SOW.

Students on one side of desk me on the other, dry of phosphorous with tissue and attach leads. Show no cur rent flowing. Leads curl up break phosphorous rod which ignites and is flicked towards students. At which point I do not quite think straight and brush the bits of burning phosphorous back towards me with my hand.

Result? My hand is now on fire, so I try to put it out by smothering it with the tissue (not thinking straight see). So now my hand is on fire AND the tissues, at which point I completely lose the ability to think straight and throw the burning tissues in the bin. So now my hand, the tissues and the bin are on fire.

Eventually I manage to get it under control. Open the windows to get rid of the smell of burning paper and, well, flesh.

I can hear outide a commotion about the smell and so decide to control it by opening the door to explain. When I open the door, holding my burnt hand behind me, there right in my face is the headmistress, together with the chair of governors.

I look at her she looks at me, seconds pass. Eventally she says "Chemistry?", I say "Yes", she says "OK" and walks off.

I had small burn holes to the bone....phosphorous was taken off that SOW.

On the plus side the kids absolutely loved it and asked for an encore.

Re: £14 billion

Except for a large proportion of the population that isn't the case is it?

"Safe seats in Parliament.

•368 seats are so safe the Electoral Reform Society has already called the result in them.

•25.7 million voters live in safe seats.

•79.3% of constituencies in North East England are safe seats, with 77.8% in Northern Ireland and 70% in the East of England.5 BBC May 2015"

About 5 out of 6 seats would need a swing greater than 10%.

I for one am sick and tired of living in a safe seat where my right to vote is meaningless as I am sure are the 25.7 million others in the same situation. What sort of lunatic voting system disenfranchises 40% of the voters?

Re: Deleting emails

Just the other week my new boss told me that she hates email and would prefer everyone to talk to each other. Well she would wouldn't she? All the more reason to follow up any conversations with thoso who must be obeyed with a "Thank you the recent chat. Can you just confirm my understanding that ..... " type email.

My advice: never delete email and always back it up. I have been able to help myself out of tricky situations ie prove what was actually said too many times by emails that others would have deleted long ago.

Just say No.

Swearing in the South

I have long held the view that if you want to hear someone swear don't ask a southerner. They just don't have the right intonation for many swear words. Bastard said by a southerner sounds almost polite, by a northerner it is rightly agressive. Same with many of the others.

Re: Just nonsense from teachers that are too dumb to do anything...

I think they may be getting at how easy it is to get the kids work to the teachers and back once marked. Google Suite for Education using Chromebooks/bases/boxes/pads makes it very easy and intuitive.

Many teachers are not technology gurus, why should they be? They just want something to work and work easily esp when dealing with 30+ kids at a time. GSFE does this.

Oh and the administration of hundreds of chrome devices used by many users each is a breeze with GSFE.

Maplin shutdown sale prices still HIGHER than rivals

ridley

I am surprised that it is 50k a year for a "large retail park unit", that seems far lower than I was expecting. Not saying it is good or anything but when, 20 years ago, I was looking for a smallish shop on a high street with a one way street with no parking they wanted 26k a year rates, plus the same in rent.

This is a high street in a town with little footfall as there are out of town retail parks locally.

I declined.

It is no wonder the high street is dying, rent and rates on shops are unsustainable in the internet age.
