Clarkson on: driving tests |
Before Quentin became an estate agent and drove around talking about people's fireplaces, he lent those dulcet tones to a programme called Driving School. You may remember it. |
It focused on people learning to drive and it made a star of Maureen, whose mouth was on upside down. |
Sadly, she never did get the hang of driving, but that didn't matter; some civil servant in beige trousers handed over a document saying that she was legally able to drive a Ferrari F40 on the Snake Pass in winter. |
Well that's just brilliant. And Maureen isn't alone. There was another woman in the programme who, having passed her test, had another lesson because she wasn't confident enough. She wouldn't be, driving around with a dog the size of a wildebeest in the passenger seat. |
Oh, how we laugh... right up to the moment when someone just like dog-woman ploughs into a primary school playground, killing 30 under-fives. |
I'm sorry, but every day I see people in cars who were born to be on the bus. Hunched over the steering wheel, airbag an inch from those half-filled hot water bottles they used to call breasts, they peer into the gloom, looking neither left nor right. |
Tom Cruise could be in the car alongside, waving his meat out of the window but these people wouldn't dare sneak a peek. They're driving along, petrified. And petrified means ‘turned into stone', by the way. |
They can't look in a mirror to see what's behind, they can't glance out of the side window to see what's alongside, they just plough on, oblivious to the mayhem in their wake. |
I found one of them yesterday doing 30 on an open, sweeping A road. The sun visor was pulled down behind her head which meant, of course, she had no idea I was overtaking when she began - with no warning whatsoever - to turn right. |
"I’m sorry, but every day I see people in cars who were born to be on the bus" |
We've all seen this and we all assume the police should be more vigilant and aggressive; but be realistic. Even if they do pull someone over they'll find it impossible to charge them with ‘sitting too far forward'. Or ‘doing 30'. |
No. To attack this we have to get to the root of the problem - the driving examiner. I have some sympathy with these poor souls. Think about it. If you are scared half to death while someone is taking their test, you'll pass them. That way, there's a very small chance you'll meet them coming the other way on a dark nig... |
If you fail them, there's a very large chance that, in six months' time, they'll be back, ready to scare you to death all over again. |
Here's the solution. First, anyone who fails their test three times is simply told that they may not apply again. They must accept that they can't drive, in the same way that I have now accepted that I'll never be an astronaut or a lesbian. |
Second: anyone who has not passed their test by the age of 25 shall not be allowed to do so. Let's face facts here. If you're so disinterested in driving and cars that you allow eight years to slip by without trying to get a licence, then you are just never going to make a good enough driver. |
Fact: if you are not interested in something, you will be no good at it. Proof: I am no good at cricket. |
Basically, the driving licence will become a privilege and not a right, and in order to get one, I'm afraid that the test will need to be modified. You'll still be expected to brake sharply and reverse round a corner; town driving will remain to ensure you have good spatial awareness. |
The written test will survive too, and don't worry if you live in Norfolk or Cornwall. I have no proposals for motorways to be on the curriculum, so you won't have to come to England. |
However, you will be taken to a circuit which you will be expected to negotiate in a certain time - nothing mad; just fast enough to make the tyres squeal on the corners. We need to see that the car doesn't scare you and that you're able to take it to the red line once in a while. |
We don't want you to break speed limits, they're there for a good reason. But, on the A44, we want to ensure you'll go at more than 30. And if you don't, you blind, deaf, old bat, we'll come round one night and fit a turbo to your Rover 400. A turbo with the wastegate jammed shut. |

I presume this question is acceptable here-- because it's a part of software development but not specific to programming. If it's better suited for another area, could someone kindly help move me? |
I know ads can be profitable for some incredibly popular applications, but how do average applications fare? |
I am about to release an application and I think it will be pretty popular, but it's not the next Angry Birds. I guess there will be a few thousand users. Would a few thousand users that use the application about 15~20 minutes once or twice a day net any actual profits? |
What are you experiences with ads like? What kinds of numbers do we need to net anything worthwhile? |

Don't know much about android but wouldn't the answer depend on your definition of "net"? Profit = revenue - cost. What are your costs? Do you consider your time to make entire app? or your time to put ads into your app? does it cost you anything to actually have ads in your app? Are you talking about economic profit o... |
There are no costs per-say, but I think ads could turn people off your app and drive away users. So the cost of ads is the potential loss of clients. – Google Jul 29 '11 at 4:19 |

I'm actually the owner of the blog @Mona mentions, and thought I'd chip in with some feedback about the current state of things. |
To answer the question - Yes, ads can be profitable for your average Android app. It all depends on how much capital you're investing in the app. |
If all you're putting into it is your time, and you're getting a few thousand people with 15-20 minutes per day total usage, you should be able to make a decent profit. Here's a few quick calculations for you: |
• 15 minutes per day = 900 seconds |
• 90 second refresh rate for ads = 10 ads per person, per day |
• 2,000 daily users = 20,000 daily impressions (assuming 100% fill rate) |
• eCPM of $0.70 = $14 per day |
• $14 per day = $420 per month, or about $5000 per year |
Some caveats with these calculations though: |
• 15-20 minutes is a long time for somebody to spend with your app. Most casual apps only get about 1-2 minutes average visit length. |
• You'll never get 100% fill rate on your ads, so figures will be slightly less than this. However, with AdMob I've achieved >94% fill rate, which is close to 100%. |
• Your eCPM will always vary, depending on ad network, time of year, and CTR. In my experience, $0.70 is a safe bet if you're doing things right. Some developers are actually getting over $1.00 eCPM, which would bring these figures up to $7000/year. |
If you're chasing more info from actual developers regarding eCPM and level of profitability, you could checkout the Income Reports forum on my website. A number of people are sharing details here about their own earnings with moderately successful Android apps. |
Velti also have an interesting "State of Mobile Advertising" report which covers many of these details on a global scale. |

I suggest to you that first you make sure that your app is realy useful and attract users, i f that is the case then just try to put your ads in conveniant places so that is doesnt bother users a lot and maybe make a paid version that doesnt include ads . also If you blog you can write about the process of developpemen... |

Grade 1 Violin failure |
(217 Posts) |

I've just had a text from my DD's violin teacher to say she's failed grade 1. |
She has been with him for almost 2 years and has practiced regularly, particularly since we've been preparing for the exam (since last September). To my untrained ear the pieces sounded fine. After the exam the teacher (who accompanied her on the piano) said she had done well and he was pleased. |
The scales and sight reading are done with the examiner only so he didn't hear these. |
By text he said she talked through the pieces but I will get full story tomorrow. |
I wanted to know how common it is to fail grade 1? Is it DD or the teacher? Should I try to switch? |
Orangepuffle Mon 04-Apr-11 18:46:38 |
I know that teachers are allowed to contact examiners and question their marks and ask for them to be revisited. Find out exactly what your examiner has said and then ask your teacher whether he feels it could be "challenged". |
seeker Mon 04-Apr-11 18:47:40 |
I don;t think it's very common to fail - but you do get a detailed sheet with marks and remarks for each section so that should explain exactly where she went wrong. |
Poor dd - how old is she? |
iirc you get a sheet with comments on each section - not lots but may be a starting point for understanding which areas need work or where you might feel the examiner went wrong if that's the case |
Honeymum Mon 04-Apr-11 19:01:48 |
She's 9. I'm just pissed off because she's been having lessons for so long and we did everything asked of us. I don't think she should have been entered if there was a chance of failing (difficult I know). I hold teacher responsible. Maybe unfair, I know but... |
What makes me cross is DH bumped into him a few days after exam and he'd gone from "she did really well" to sucking his teeth and saying he didn't know how she'd done. He was unsure as to whether you have to pass all elements as well (shouldn't he know that?)...and what made me angry was that it was only then that he s... |
I am emotional about it. It will be very difficult to tell her and motivate her from now on and I don't know if she would have been ok with a different teacher. |
Honeymum Mon 04-Apr-11 19:02:33 |
It was like he was shifting the blame. That makes me think we need to switch. I don't think I can work with him even though DD loves him. |
I used to teach violin and both my mum and sister are music teachers. IME it is pretty rare to fail grade 1. |
I once had a child who barely scraped through, but she was severely dyslexic and unable to read music in any meaningful way so sight reading was always going to be a challenge! |
I think it depends on how the teacher has approached this. If your daughter has practised regularly and has no particular issues that make it particularly difficult for her to learn an instrument then I would nornally expect that she would be able to reach a suitable standard for Grade 1 within 2 years, although obviou... |
How experienced is the teacher? What grade do they teach up to and what is their pass rate? Did the teacher not raise any concerns with you in the run up to the exam? Whilst you make a judgement at the time of entering a pupil as to whether they are likely to be good enough by the time of the exam, I would have expecte... |
It is always possible that something catastrophic happened in the aural, scales or sight reading, but again I would have expected the teacher to include practising these skillls as part of the lesson and therefore to be aware of whether she was managing them ok. |
Tbh if she was my daughter and was keen to progress on the violin I think I woukd probably move to an experienced teacher with a good reputation and references |

You can only dispute the marks if there is a discrepancy between the comments dn the marks given. (an ABRSM examiner told me this). |
The teacher should know how the exam works. You don;t have to pass all elements for ABRSM (I failed Grade 8 scales) but have to reach the overall pass mark. |
Sometimes you get an examiner who marks harshly, last year my students had a LAMDA examiner who I felt really marked everyone down and of course there is no accounting for things happening on the day but as the teacher was actually in accompanying most of the exam should have an idea if things went that badly. |
it doesnt add up to me. |
Honeymum Mon 04-Apr-11 21:18:22 |
Thankyou everyone and thanks esp to pushmepullyou. |
She does practice regularly and has no issues at all - she's very good at school all round, and loves music and dancing generally. She enjoys her violin lessons and has a nice relationship with her teacher. I don't know about the teacher's pass rate. He teaches up to grade 8 on both violin and piano but is a violinist ... |
I don't think he covered enough sight reading in the lessons. I know that she didn't do much of that at home. In the exam I think she stalled and said she couldn't do it. But her pieces were good. I can imagine that she would stop if she made a mistake and ask to start again (she's a chatterbox) but the teacher gave no... |
