Use your credit card in Canada? Pay an extra 3% fee.

Currency conversion costs

I'm hardly a credit card newbie, but this one really surprised me. My VISA statement this month had a surprising line entry:
07/14 00000000 PURCHASES*FINANCE CHARGE*FOREIGN TRANS Standard Purch 49.5
I get hit by some credit card fraud about once a year or so (I expect more thanks to the vast amount of stolen card data now on the market), I thought this was another example.

Not so. It was a 3% fee Citibank VISA places on all "international" transactions.

It turns out Citibank VISA has very, very quietly included this fee for years, perhaps decades. Recently, however, it's been split out as a separate line item. Hmm. Such sudden honesty among villains is a wee bit suspicious. This couldn't have anything to do with the November 2004 New Zealand Commerce Commission action, could it?

So now the story is out. Citibank is not unusual, VISA always charges 1% and most banks kindly add another 2%.

AMEX does better with a 2% conversion rate, but AMEX is not well accepted internationally.

Years ago I was taught that the simplest way to manage exchange rates was to use a credit card. That's no longer true. In the future I'll use my ATM card to get cash, and forget the credit card.

Sometimes it's hard to keep straight what company to despise more -- my cellphone company (Sprint), my phone company (Qwest) or my credit card company (ok, so there's Microsoft too). I think today my vote is for Citibank VISA.

PS. The great thing about America is there's always a starving lawyer somewhere in desperate need of a class action suit to pay the bills. Sick 'em Rover!!

Accreditors Blamed for Overlooking Problems (print format)

This is Part II of what will be a three part series. I'm looking for a link to Part I. This could turn out to be a significant work of journalism.

Infinite Gmail?

Gmail - Inbox
You are currently using 257 MB (11%) of your 2428 MB.
Once I got to 11% of my 2GB allotment, Gmail started increasing my maibox size to keep my allotment there (why 11%? prime number? symmetry?).

So it's now 2.5GB and still growing.

Update 10/5/09: It's 7GB now, but I use it faster than it grows.

Google Maps - Hybrid Mode

Google Maps - 55105-2007

Google Earth offers various layers over its images, including street names. Google Maps brings something similar to its mix; in hybrid mode a new layer includes very well placed street labels as well as universities and colleges. For most users Hybrid and Map modes will be the two best options.

Constructing Your Own Universe

Add cold dark matter and bake.

I love this stuff ...
Constructing Your Own Universe | Cosmic Variance
So this is what Carlos was talking about. There are wonderful sets of simulations which he talked about, called the “Millennium Simulation” (ahem…remember an earlier post?). The bottom line is that these guys simply took really big computers and put in as much as we know about the basic equations of the universe, and then play with sprinkling in different amounts of cold dark matter and simulate the evolution of the universe tracking 10 billion individual particles in the simulation. They let the computers run until they get to the equivalent time of where we are now in the universe, and then then stop and look inside the computer. They take out the universe they’ve made and compare it to our universe. For that, you need to do an accurate survey of where all the stars and galaxies are in a large piece of the universe so that you can get good data on the distributions of the lumps, and other structures. The survey his team compared to was the “2DF” survey.

So what did they see? How well did their universes do? Well, in short, they look an awful lot like our universe when you have (the right amount of) cold dark matter sprinkled in. (”An awful lot” is not yet an established scientific term. Heck, it is not established English either. However, there are very specific tests (comparison of the power spectra of the size distributions of the structures) which work very well.)

This is great stuff, and confirms several other pieces of work by other teams. (See the references in their paper I’ll give the link to below.)

Here’s the really fun part you can do right from here. You can look at all the wonderful slides he showed by looking at the video of this talk when it comes up on the SUSY 2005 site, but even better you can download some of the high quality movies he showed right now! These are movies of flying around inside these newly created universes and seeing all of the wonderful organic-looking structures which form due to the clustering seeded by the CDM. You can see some of the hotspots that form at the intersections of some of these filamentary tendrils, which will be the birthplaces of stars. It is all rather beautiful.

Cosmic Variance: A physics blog?!

Cosmic Variance

Arguments about string theory and created universes. All Caltech alumni are hereby summoned to this feed ... (Even the english majors did a semester of QM -- physics runs deep in our blood.)

Warning: this blog is addictive to certain people, the posts are long, and they don't read quickly. Get your coffee and an easy chair ready. They are not technical, however -- they're written for a general audience.

Why didn't the bombs blow up?

BBC NEWS | UK | Police issue bomb suspect images

A bad batch of explosives? A rush job? Some speculate that there was great cleverness involved, but it's more likely to have been incompetence:
BBC security correspondent Gordon Corera told BBC Radio 4's Today programme the devices were so similar there was speculation they could have been part of the same batch.

'The explosive might have degraded over time or had not been put together right in this case, or it could have been a completely different batch of explosives - homemade - that had not been cooked up properly.'

The bombers' plan might have been disrupted by the investigation into the 7 July attacks, forcing them to act before they had been fully prepared, Corera added.

Some witnesses said the Thursday's attackers seemed 'scared' or 'surprised' when their bombs failed to explode properly.
It must be a rather peculiar feeling to detonate a suicide bomb -- and live. There is still the unlikely possibility that someone sabotaged the attack.

The Transparent Society lives: surveillance images of bombers

BBC NEWS | UK | Police issue bomb suspect images

David Brin, author of 'The Transparent Society' really ought to be a part of today's interview circuit. Too bad the media isn't more imaginative.

This is the world he predicted, a world of ubiquitous surveillance and crimes that are solved within hours. These images have had minimal processing, but I don't doubt they will identify the attackers. Within a few years processed images will show the size of their pupils.

Why don't we know yet why "they" hate us?

Why Do They Hate Us? Not Because of Iraq - New York Times

Olivier Roy thinks "they" [al-Qaeda's army] hate us for cultural reasons, not religious reasons:
It is precisely because they do not care about Afghanistan as such, but see the United States involvement there as part of a global phenomenon of cultural domination.

What was true for the first generation of Al Qaeda is also relevant for the present generation: even if these young men are from Middle Eastern or South Asian families, they are for the most part Westernized Muslims living or even born in Europe who turn to radical Islam. Moreover, converts are to be found in almost every Qaeda cell: they did not turn fundamentalist because of Iraq, but because they felt excluded from Western society (this is especially true of the many converts from the Caribbean islands, both in Britain and France)...

...The Western-based Islamic terrorists are not the militant vanguard of the Muslim community; they are a lost generation, unmoored from traditional societies and cultures, frustrated by a Western society that does not meet their expectations. And their vision of a global ummah is both a mirror of and a form of revenge against the globalization that has made them what they are.
Other writers think it's our policies -- change our policies, forget Israel, leave Iraq, don't meddle -- and the attacks will stop. They make good arguments too, though they sometimes tend to reference the Iraqi insurgency rather than to al-Qaeda itself. There may be more than one class of reason to hate America and the UK.

Four years ago, I put together a post-9/11 model that included many contributing factors to the hatred equation. It had some similarity to typical crime models - motive + capability + opportunity. I thought then, and still think, that fear of feminism is a "significant" (10%?) contributor to "motive" -- but there seems to have been no testing of any model, much less my amateur effort.

The interesting questions is then -- why do we seem to have made little significant progress on this key question? Is there no body of research and analysis? No attempt to create and test predictive models? Why didn't Bush fund a 'Manhattan Project' of social science research to understand the enemy? Did he think it was only necessary to crush them with overwhelming force?

What idiots we are. The cost of havoc continues to fall as technology disseminates new and old knowledge; we must either kill all who might hate us (a futile and evil goal) or convince them to hate us much less. (If all we did was convince us to hate us 50% less, the falling cost of attack would overwhelm such seemingly significant gains.) Can we win by increasing educational opportunity? By hiding western feminism from view? By showing impressive brutality? By letting the global economy work things out? By accelerating social transformations and gritting our teeth as Gulf societies become more technocentric? These are not irrelevant questions. We ought to have better data and more reason.

Instead we have faith-based government, and the power of the Will. History will not forgive us for re-electing George W. Bush.

How can we get grown-up leaders?

BBC NEWS | UK | London attackers 'meant to kill'

London is attacked again, though in a rather odd fashion. (Was the attack sabotaged?)

Ken Livingstone, mayor of London, basically says (via NPR) that there are really no magical solutions and that everyone will have to make do. Things will be done, but they will not fix the problems. Promising technical solutions (explosive sniffers) are still years away.

If an American politician said such things they'd be tarred, feathered, and fired.

I suppose to get grown-up leaders, we'd first have to grow-up ourselves.

Backing up OS X 10.4 using Retrospect Professional for Windows

Support for OS X 10.4 (Tiger) Clients?

Dantz's Retrospect Professional for Windows can be used to backup up OS X, Mac Classic or PC client machines. Their web site doesn't say whether it can backup up a 10.4 (Tiger) client. In this thread an expert says that one can install the Retrospect 6.0/Mac client on a Tiger machine and it will work.

I'll give it a try.

The end of all the prayer studies

Skeptico: Prayer still useless

This is a remarkable review of studies that have claimed to show prayer altered disease outcomes. There had been some poorly done and very small studies that suggested an effect, so it was worth doing some larger studies. The results of the larger studies are all negative.

Prayer to alter the course of disease doesn't work. What effect there was appears to have been a combination of poor study design, data mining for correlations, and perhaps some publication bias (negative studies by persons seeking positive results may not have been published).

I think that theists should find these results reassuring. I would be disturbed if a God were responding to such pleas; it is one thing to live in a world of freedom and suffering, another to live in a world of suffering that God could alleviate -- if He felt like it. For the people He liked.

Pray to God for wisdom, or for help to bear the pains of the world, or for faith or tolerance or greater compassion. Pray not, however, to be spared the pain of our world.

A new Microsoft?

Yes, it might be good business practice, but even self-serving charity is not what built Microsoft. They must be feeling a need to change...

The Economist: what makes a murderous zealot?

Muslim extremism in Europe | The enemy within | Economist.com

This is an exceptional article, it must have been in development for some time. The Economist has summarized the most recent thinking on what makes some people fodder for extremist organizations.

I found a few themes to be of particular interest. One is that the recruits are often drawn first to the cause, and secondly they seek out a murderous mentor. In other words, they are not recruited by an individual, they are recruited by a meme. Personal failures, and in particular fear of dominance by females, are often precipitating factors. Poverty is not so important as personal alienation from family and society.

The role of electronic media in distributing these memes, and in facilitating discovery and communication, is critical. The Internet, of course, has an important facilitating role. It is the communication with an experienced mentor, often mediated by the Internet, which transforms ineffectual but motivated zealots into effective killers.

One of my college hobbies was accepting invitations to attend cult gatherings (Eckankar, Moonies, etc -- Scientology was too creepy for me). I liked meeting these rather different people, and seeing what made them join the cult. Most of what I saw in those cults 25 years ago is reiterated in this article.

Recommended. I would also like to point out that a picture I drew almost four years ago is fairly compatible with this article (note the "female" circle and cultural dislocation).

EarthLink� Wireless Service

EarthLink Wireless Service with Treo%u2122 650 - FAQ

Earthlink is a national ISP; they bought Mindspring back in the 1990s. MindSpring was the second ISP I used (I started out with an obscure company in Colorado back before commercial ISP services were really established); I still have a Mindspring address and thus a connection to Earthlink.

Earthlink now sells cellular service. They're not so different from Sprint, except they have better data plans. I suspect they're using Sprint's network; they're CDMA and the coverage map looks like Sprint's (there's no analog roam though!). I'd give it a look, except I'm waiting to see what Apple does in the next 2-3 months.

They feature the Treo 650 and the BlackBerry 7250.
