Toucan··on Apple cuts iPhone 3GS price to $49
First off, I'm afraid I don't understand what a phone subsidy is, perhaps we don't have them in the UK or I've never seen them on a price plan here.

Assuming it's something you pay for owning a smartphone, would it still be there for a smartphone that costs nothing? If so, then the extra cost for the iPhone is still $49.

The comparison ought to be an iPhone v another smartphone and contract with comparable features, not an iPhone v not buying a phone at all.

Toucan··on I've made Dayta free
True, but what would be valuable is a blog post describing the thought process that led to this decision and what the perceived advantages and disadvantages are. If this is an experiment, it would be good to know the hypothesis.

It would be great to see a post in a couple of months time following up on the decision as well.

Toucan··on What was it like to fly the Concorde
Yes, for people with arrest warrants for example.

It also gives information on people who are overstaying visas, which can be taken into account if they apply again in the future.

Toucan··on Why your child's school bus has no seat belts
When taking a big fall rock climbing the advice is to relax, enjoy the fall and shout something. Animal noises are the most fun, expletives the most common. The shouting is to make sure you're breathing out as you fall onto your harness rather than breathing in, and to give you something to concentrate on so you don't tense up in fear.

I'm not really sure why it helps, but I can certainly say it does. I know that when I panic and go stiff it hurts more as my tense body hits the rock. Even when in a similar mental state, hitting the rock with a relaxed body is less painful.

Toucan··on Reversal on Carbs: Scientists now blame carbohydrates for America's ills
I wasn't arguing against this article being contrary to public opinion, more that it's not a change in what science has said up to this point. I'm more concerned about the damage done by provocative headlines such as these that imply that scientists have changed their minds. There's no new research or evidence here.
Toucan··on Reversal on Carbs: Scientists now blame carbohydrates for America's ills
This isn't a reversal, at least not on the part of scientists. Reporting like this just reinforces the public's idea of "Why should I do what doctor's say? They just change their mind. First it was eggs..." and so on. Seriously, ask your mum.

Scientists have known about insulin sensitivity and why and how weight gain/loss happens for a long time. Bodybuilders and other sportsmen and women listen.

http://www.motherearthnews.com/print-article.aspx?id=139058 is an interesting article on what actually happened. In contrast with the "oh those silly scientists, always changing their mind" headline, that article states 'scientists have known what makes us fat for almost half a century'.

Toucan··on Inside Rockst*r Games
It loads, it just takes a long while.
Toucan··on Fred Wilson's Nexus S Review
I think it's more likely that he means taking a photo of yourself is easier with the front camera, as you can see the image on the screen as you do it.
Toucan··on Wondering if you are getting a CR-48? Look for your zipcode here.
What degree of knowledge should be assumed?

There's plenty on HN that I don't understand but I'm yet to come across anything that 30 seconds with Google couldn't explain.

The only knowledge that is a pre-requisite is how to find information on the internet.

Toucan··on How the iPad fired my building Watchman
Various dialects of Indian English are still quite similar to British English during the 18th/19th centuries, which is why sometimes Indian English sounds quite archaic (do the needful, etc.).

Emphasised nouns are capitalised in some of the older 19th century books I own, so I suspect this is just another characteristic that remained in some places.

Toucan··on Why Does Apple Offer Free Engraving?
Is there a specific reason it has to be an Apple monitor? I have an HP IPS monitor with DisplayPort that I use calibrated with my MacBook Pro. What am I missing out on?
Toucan··on How being a bully fuels this trader's profits because of Google
But you'd have to do that for each brand that he sells. It's not the DecorMyEyes keyword that people are getting the "wrong" result for.
Toucan··on The Death Of RIM
I've used both the phones in your post and by and large I agree with you. That said, you seem to be talking about phones in a business environment. Do the users of the phones you're talking about own them? I wonder if they treat them with less respect if they can get a new one just by dumping it on your desk every 3 months.

I'm not saying the problem isn't there, just it might be exacerbated by user behaviour that RIM didn't anticipate.

Toucan··on Iphone Application Development - Course from Stanford
This is a more recent version of the same course (CS 193). Fall 2010 being newer than Winter 2010 caught me out too, but it made sense when I thought about it in the context of the academic year.
Toucan··on [dead]
It's still a discount on most of the individual packages.
Toucan··on Exercise 'can prevent a cold', a study shows
You're confusing the reporting of science with science.

The news article contains what (the media think) the public would want to know of the results.

The actual study (I'm not sure I can find it, but it appears to be a follow on from: http://www.medscape.com/viewarticle/497802 ) will use scientific methods to work out why this is true, not just that it is true.

Toucan··on Ask HN: I built it, "they" didn't come...
Look at Apple. So many competitors have sprung up based on features that are missing in the existing products. Apple still win the consumers.

It's more than adding features to a product.

I suspect Facebook is easy to use because people can see the benefit in learning how to use it. They can see how tagging an image is a cool thing, so they'll make the effort. If they can't immediately see how upvoting a question is a cool thing, they won't bother to understand how to use it.

Toucan··on A Google Suggest Venn Diagram Generator

This is superb! Some odd handling of spaces though. See: http://www.technomancy.org/google-suggest-venn/#start=Why+is...

Toucan··on A Passenger's Wish List for Improving Airports
Reading this, my first thought was that it's certainly nice that Heathrow Terminal 5 has faster than normal baggage reclaim and smoother security procedures, and that Calgary International Airport has free wi-fi outside the Tim Hortons, but it's never going to sway my decision. If I have to travel by air, I have to travel by air.

Then I actually thought about recent times I've travelled by plane and I realised that competition does exist in London at least. I have:

Spent £50 more (a 70% fare increase) to fly to and from London City Airport. LCY is smaller and as such seems to be much more efficiently run. There's no long walk/shuttle between security and the gate. Security takes all of 5 minutes at most. The check-in desks have no or very short queues and there's seating nearby if you do have to wait. It's closer to the city centre so there's a 20 minute transfer instead of an hour long transfer between the airport and London. This extra expenditure netted me a nicer airline as well, but the main justification was the airport. About £20 of the cost was mitigated by not having to travel to another airport on the outskirts of London (with the exception of the ~£8 journey to and from Heathrow)

Spent £50 more (a 10% fare increase) to fly to and from London Heathrow Terminal 5. The terminal opened in 2008 and is very modern. Baggage reclaim seems faster than other airports I've visited, the overall layout is more sane and security tends to move quite fast for an international airport. It's certainly worth a little extra in my opinion.

There's room for improvement. I still prefer the 4 hr 30 train journey from London to Edinburgh v. the similar priced 1 hr plane journeys. Air travel might win if it can beat the convenience of just turning up at the train station 20 minutes before the train leaves, only paying a small extra fee if I want the freedom of using any train that day instead of a specific train and compete with the fact that the train stations are in city centres, whereas the airports are on city outskirts. These problems are quite hard or impossible to solve, so it's going to have to try harder in other ways. Oh, and the trains have (somewhat spotty in parts) wifi as well.

Toucan··on Ask HN: Show me your Half Baked project

For others, this helped me understand the basis of timing attacks.

Toucan··on Do Intelligent People Drink More Alcohol?
My expectation would be that more intelligent children have more demanded of them, and go on to choose or take more stressful careers. Are there any studies correlating stress levels and drinking? Personal experience would suggest a relationship.
Toucan··on Chess boxing
It would seem that's just for WCBO Championship fights. The amateur boxing world is almost entirely self-regulating.
Toucan··on Chess boxing
Completely anecdotal, but I've tried chessboxing (as an amateur) a number of times. I'm an awful, awful chess player but a decent boxer and I'm reasonably fit.

Personally I've found some sort of link between mental and physical exhaustion, though I'm not sure which causes which.

I think that being struck in the head probably leads to a loss of control and an overall inability to remain cool more than it affects mental capacity. People panic when someone's trying to punch them. That said, the more experienced (and physically fit) a boxer, the longer they can last before becoming overwhelmed. I don't think it's as simple as purely a mechanical reaction to being punched in the head.

Toucan··on Sharpie reinvents the pen with liquid pencil
Montblanc make mechanical pencils. As do most of the luxury brand manufacturers (there are many who make more expensive pens than Montblanc.)

This is potentially better then lead in that it's permanent after a while. I wonder how permanent, but it's certainly true that pencil notes on paper don't come close to archival quality.

Toucan··on Ask HN: Do hackers use standing desks?
I do.

It's not so much a standing desk as a lump in my room (there's a staircase below it) that comes up to about waist height.

Laptop goes on a couple of boxes and a riser to get to eye height, keyboard and mouse go on a large board on some more boxes.

It's extremely comfortable for hours at a time and I certainly find it easier to concentrate. There's less of a temptation to recline back in a comfy chair and watch YouTube videos all day.

Toucan··on Is that Hacker News web page optimized for iPad? Yes it is
There is an iPhone app already: (not mine) http://itunes.apple.com/us/app/hacker-news/id339408916?mt=8

A lot of the complaints are for older versions, you can at least vote now.

Toucan··on Last roll of Kodachrome film goes through last Kodachrome lab
The headline is mildly ambiguous.

To be more precise, this is the last roll of Kodachrome which was produced. Not the last roll of Kodachrome which Dwayne's will develop.

From Dwayne's website:

Kodachrome Film Status: The last day of processing for all types of Kodachrome film will be December 30th, 2010. The last day Kodak will accept prepaid Kodachrome film in Europe is November 30th, 2010. Film that is not in our lab by noon on December 30th will not be processed.

Which is a great relief to me, because I still have 3 rolls of film I'm saving for 3 special occasions over this summer.

Toucan··on Ask HN: How do I estimate app hosting costs?
I've run a 250,000 pageview/month vBulletin forum (MySQL and PHP, you can judge for yourself how efficient you think this would be as a comparison) off a server destined for the scrapheap:

1.8GHz Celeron, 512 MB RAM, 1 x 5400rpm IDE disk

For both httpd and mysql.

The server occasionally got a bit loaded during peak times (geographically specific market), I'd say I was operating at roughly 80% of capacity, about the edge of comfort.

This was just a hobby site on the side, you may want to consider the additional costs of redundancy, off site data archiving, perhaps even splitting infrastructure across two datacentres and hosting providers just in case.

Ideally, you'd have access to the application in order to run your own capacity testing, can you arrange that?
