Its a flaw in the auction design. A simple rule as the closing time will be extended by x minutes after the last bid would solve this.

Do you think the perception of crime/safety might be an explanation? The difference with three decades ago is the ease of information distribution with social media/internet. Most likely also media coverage has shifted more to crime reporting.

If I'm not mistaken Levitt describes this perception of crime in his book, Freakonomics, as well.

True, the suburbs explain some of it. However, I've been told it would be a big no-no to let your 8 year old play in the park a few blocks away without supervision. Parents who do so are apparently considered irresponsible.

Do note my source is only a single colleague from CA, could of course be an exception..

The Dutch have a similar approach albeit at a bit older age. During my last visit to the US I was really astonished when my colleague told me he was driving his kids (12-15 years old) everywhere anytime and that this was common.

One of the best moments of my childhood were those in which you could stroll around the city in full freedom.

I still don't fully get the protective attitude of US parenting. I wonder if it has to do with crime stats being higher.

That is not true at all, wafer throughput is a factor 4-5 less... The mistake in the first comment is that with self aligned double patterning you only need one litho step, not two. The same applies for SQDP. And since litho is one of the most expensive steps double patterning is more cost effective.

From a technology point of view the problem with EUV is more the line edge roughness, line width roughness, defects and the reliability... Given, more light will make the job easier

To me, you are describing one of the core problems of ad networks. As long as they are not accountable (or simply never have to account) for malware distribution ad blocking will be the best protection...

This is a difficult one, I'm really excited about lithography and want to share my knowledge but since I'm working at one of those firms (dislcaimer here) I can share little...

So, let's stay safe and share some public knowledge:

1) The article mentions source power being a major factor and a huge improvement has been the addition of the prepulse (pancake). Here a great video showing how this concept works: https://www.youtube.com/watch?v=bRbHDtPbHe0

2) Short, beginners level, introduction how the EUV source works (note: this movie is made before ASML tookover Cymer, so some history here): https://www.cymer.com/euv-lithography/how-an-euv-light-sourc...

3) Chris Mack's coverage of the last SPIE conferences give a nice summary of the field: http://www.lithoguru.com/scientist/conferences.html Note that Mack is an EUV-sceptic, his views on EUV are not commonly shared.

Thanks, reading it more carefully I see I missed more info... Anyway, 86 participants, divided in two equal groups. Let's say the 43 participants in the loser group all threw the dice once you'll end up with a ~9% chance of the groups average to be below 6.5. So that might well be possible. The winners group throwing on average above 9 is highly unlikely purely by chance. Quite interesting.

Does someone know if this research has been published and is freely accessible? The difference of the losers of -0.5 compared to the expected value gives me the feeling N is not pretty high...

The example he gives is heartbreaking, however the solution he poses is only treating, in this particular case, symptons of two other issues:

Why does it take 2 years to stand trial for a petty crime? Why is the accused sent to prison while awaiting trial for a petty crime?

Edit: added 'in this particular case'

Thanks for sharing! This list is a list I actually expected the OP's list to be. Probably because I'm also more likely to view the Ask HN threads about books.

Even from a theft perspecive it is bad design practise to have this placed outdoor... Why not place only the camera and button outdoor and have a simple wire connection to the wifi module.

It's such a design flaw it becomes even funny

Unfortunately I cannot help you with your question, I haven't found anything cheaper than building your own. And that's going to cost you >200USD.

I do have some advice before you invest in a drone. Buy a cheap non-programmable mini-drone first ~15 USD. Flying a drone is not easy, you'll crash a lot in the beginning and you rather wreck such a mini-drone than a more expensive one. Plus, mini-drones are almost indestructable.

Well... yes and no... Rand divides all the characters into two groups, to put it simple into the socialists and the capitalists. The capitalists get the virtues of honesty, integrity and are rational and so on, while the socialists are depicted as dishonest, corrupt, irrational etc.

If you fail to understand these characteristics are not necessarily tied to either of the groups, yes the warning label is appropriate. If you do understand this - and I hope some males between the ages of 13 and 21 do - this book can help you improve your attitude towards work. After reading Atlas Shrugged I must say I'm more eager to get things done and ignore pessimistic people who think things simply cannot be done because it is a lot of work.

It definitely helped me.

Thanks for the info, I've added it to my to-read list.

What is your opinion on The Guns of August? I'm still looking for a good book on World War I.

I'll skip some mentioned already by others. Books I really enjoyed this year:

The Wright Brothers, David McCullough - wonderful book on the Wright Brothers, easy to read, shows that persistence and logic thinking pays out. 5/5

The autobiography of Malcom X, Malcolm X - Nice bio, a bit repetitive sometimes. 3/5

Atlas Shrugged, Ayn Rand - Although the book has more than 1200 pages it really kept me going. I read this book to get a better understanding of the ideology of some republicans. Fun read. 4.5/5

Freakonomics, Steven D. Levitt - Levitt studies all kind of different everyday questions using economics. 4/5, short, easy to read

Guantanamo Diary, Mohamedou Ould Slahi - Diary of a Guantanamo prisoner who has been imprisoned since 2002. The US has never charged him with a crime. Profound and disturbing. 5/5

No place to hide, Glenn Greenwald - Story on Edward Snowden, probably read by most of HN. Enjoyed it, that's it. 4/5

How to lie with statistics, Darrel Huff - Short book on statistics, easy to read and fun. 4/5

I can vouch for the first two of these books: 1. "Surely You're Joking, Mr. Feynman!", fun bio, made me buy the Feynman lectures as well. Really glad I did. 2. "Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future", Very inspiring indeed.

Thanks, makes complete sense now to me.

I highly doubt your first statement. Solar, for example, is no burden since if you do nothing it would land on earth anyway.

For fossil fuels you release chemically stored energy as heat. The same applies for nuclear power. Which is an additional thermodynamic burden...

Does somebody know if nuclear power will actually be an improvement for the environment (only considering temperature here)? Essentially you just release heat which is stored as mass.

A quick calculation shows that if you only consider heating up our atmosphere and assume an entire switch of all our energy consumption to nuclear energy you end up with a temperature rise of 0.1 deg C per year. I know it is a worst-case scenario - energy will be stored in land/water as well, dissipation etc. - but still.

Compared to fossil fuels, the plus side is you do not produce any greenhouse gases. However, I'm unsure which contributes more to global warming, could well be the former is negligible. Would love to hear an expert on this.

The math is rather easy, it is however questionable what you define as one of the largest nuclear power plants. Most power plants have multiple units, if you take the power per unit you more or less end up with 20 years.

Capacity of large nuclear power plant unit: ~1 GWe [1] Total world electricity consumption is 20,900 TWh/year [2], of which 40% is generated by coal power plants. A total power of ~1000 GWe, so you'll need 1000 nuclear power plants to replace all coal-fired plants by nuclear power plants.
