“Muslim demographics” propaganda video exposed

Today a friend forwarded me an email with a link to a Youtube video on “Muslim demographics” that appears to be viral at the moment, with over 5 million views so far:

Islam will overwhelm Christendom unless Christians recognize the demographic realities, begin reproducing again, and share the gospel with Muslims.

It’s a cleverly made piece of propaganda that paints a picture of a Europe in which Muslims become the majority of the population by or before 2050. However it did not clearly reference its sources, which (if you notice them at all) appear too small to be readable. It’s not clear who produced this video either.

Why do I call it propaganda? Because whoever made it, they did play fast and loose with the truth – Goebbels would have been proud of them. I will give you just a few examples.

They claimed that the average fertility of Muslim women in France was 8.1 children per woman, which would be about 4 times the French average. The fact is that most Muslims in France originated from Morocco, Algeria, Tunisia or Turkey, countries whose average fertility rates are much lower than claimed for the Muslim immigrants.

Morocco 2.57
Algeria 1.82
Tunisia 1.73
Turkey 1.87

That doesn’t really make sense. It seems likely that fertility amongst immigrants would fall somewhere in between rates in their country of origin and of their new chosen home, but not some four times higher than either of them, as the makers of this propaganda video would have us believe.

Birth rates have been falling with rising living standards and education levels – not only in Europe, North America and Japan but also in Latin America, South Asia, East Asia, most of the Middle East and just about anywhere else. It’s a global trend: These days even the Islamic Republic of Iran, not exactly a bastion of Western liberalism, has a lower fertility rate than France. In fact sub-Saharan Africa is the only region worldwide that has bucked the trend, where fertility rates have remained consistently high. A large percentage of future Christian and Muslim worldwide population growth will come from that continent.

Another example is false claim in the video that Muslims make up 25% of the population of Belgium, when in fact they only reach that proportion in the city of Brussels, while they constitute a mere 4.0% of the population of Wallonia and 3.9% of the population of Flanders, the two major regions of the country. The national average is 6% – only one quarter of what the video claims. The video authors are off in a similar way in a similar claim about the Netherlands.

These and numerous other mistakes and inconsistencies are exposed and thoroughly refuted in an excellent post on the Tiny Frog blog. If anyone sends you a link to the “Muslim demographics” video, send them back a link to the facts!

Demographics and Politics

With falling birth rates in many developed countries and rising immigration that partly compensates for this, many people are afraid of their countries gradually losing their cultural identity. This fear is largely misplaced. When Polish workers came to the Ruhr area of Prussia in large numbers to work in coal mines in the 19th century, there were the same fears, but now their descendants are as German as anyone else and only the numerous Polish surnames in the phone books or local football (soccer) teams remind of the immigration. Likewise, Catholic immigrants from Ireland, Italy and Mexico faced a lot of hostility in the US around the turn of the 19th/20th century, but they integrated like Protestant immigrants before them and their descendants speak English like other Americans. With immigration patterns such as in Europe and the US, immigrant populations will largely assimilate within two or three generations, even if they may retain some elements of their parents’ and grandparents’ culture.

Unfortunately most people who have watched this propaganda video will not see the real facts any time soon. There is a good chance this video will have had an effect on them, sowing seeds of fear and mistrust that others will seek to exploit for political gains. Nazi chief propagandist Joseph Goebbels’ would have approved: “That propaganda is good which leads to success, and that is bad which fails to achieve the desired result,” he wrote. “It is not propagandaโ€™s task to be intelligent, its task is to lead to success.” (see Joachim Fest, The Face of the Third Reich).

Whoever made this video does not care about the real numbers or facts, or they would not consistently get their facts wrong by such wide margins. What they are trying to do is to stoke fear. As one person wrote who forwarded the link to my friend: “WATCH THIS AND BE AFRAID – VERY AFRAID.” People who are afraid are easier to manipulate: They will want to give power to whoever is promising to protect them from the perceived danger. In 1933 Hitler assumed total power in Germany after scaring the country of a supposedly imminent communist coup (by having his troopers secretly set fire to the Reichstag). Look what George W. Bush, Dick Cheney and Co. managed to get away with when Americans got really frightened after 9/11! Fear is a powerful weapon at the hands of those unscrupulous enough to exploit it.

Compact fluorescent lights (CFLs) and mercury

In December 2007, Congress passed a bill and President Bush signed it into law that would ban conventional light bulbs by 2014, starting with 100W bulbs in 2012. In February 2009 the European Union’s Environment Committee voted to phase out conventional light bulbs, starting with 100W bulbs by September 2009. Australia and Canada have similar laws, which seek to encourage consumers to switch to more energy efficient compact fluorescent lights (CFLs) that also fit conventional fixtures, but use some 75% less electricity and last up to ten times longer.

Though CFLs are more expensive to buy (from about $3 compared to conventional light bulbs at 50 cents), they will actually pay for themselves via a lower electricity bill over only a couple of months. Also, because of the much shorter life span of conventional bulbs they would be more expensive to run even if electricity were free: At 10,000 hours per CFL and 1000 hours per light bulb, you’d end up buying 10 light bulbs that cost more than the single CFL that matches their total life span.

Nevertheless, there are other criticisms brought against a switch to CFLs. One of them is the fact that CFLs, like all types of fluorescent light, contain small amounts of mercury, a toxic heavy metal. They need to be handled carefully so as not to break them. Dead bulbs must not be thrown into the trash to go into landfills or garbage incinerators. Many electrical stores or recycling centres will take them back to dispose of them safely.

However, even if most consumers dumped old CFLs into the garbage bin, it is doubtful if this would cause more environmental problems than sticking with Edison’s old invention. In many countries, cheap coal provides a major portion of electricity. In the USA it’s about half. Unfortunately coal contains trace amounts of mercury, which goes up the chimney when the coal gets burnt. This makes for some interesting numbers:

  • Annual mercury emissions from coal fired power plants in US (1999): 48 tons
  • Electricity saved in US by switching all incandescent lamps to compact flourescents: 7%
  • Equivalent mercury pollution reduction: 3.36 tons
  • Typical amount of mercury in a CFL: 4 mg
  • Number of improperly trashed CFLs per year it would take to match mercury pollution reduction from switching to CFLs: 1,000,000,000
  • Number of CFLs sold per year: 330 million

Note that mercury content in CFLs is gradually being reduced. According to a July 2008 fact sheet by Energy Star, the average mercury content in CFLs dropped at least 20% during the previous year. Some models now contain as little as 1.4-2.5 mg of mercury, driving the break-even point up to 2 to 3 billion improperly trashed CFLs per year.

Better consumer education can avoid mercury pollution, whether it’s from lamps that should not be in the garbage or from coal that should not need to be burnt due to more efficient lights.

A recent New York Times article raised some questions about failure rates of cheap CFLs. Probably the bulbs I buy are not as cheap as those mentioned in the article (I used to pay about $10 a decade ago, maybe $5 now), but in all the years that I’ve been using CFLs I have yet to experience one failing in its first year.

Here in Japan regular fluorescents (non-CFL) have been very common in homes for decades, as people here like their homes brighter than in the west, which would have used a lot more electricity and put out much more heat with incandescent bulbs.

The average Japanese dining room, kitchen, living room or bed room uses either circular or straight fluorescent lights, but CFLs have become very common where incandescent bulbs were in use before.

When I moved to my current home 9 years ago and had to buy new lamp fixtures for all the main rooms, I installed CFLs or circular fluourescents throughout. The living room and the dining room table are only on their second set of CFLs during all these years.

Most of the first generation of bulbs in those rooms didn’t actually burn out before being replaced, but merely lost some brightness (the phosphor coating gradually wears out), so I swapped them for a new set and gradually reused the old set to replace less frequently used incandescents left in the house.

CFLs are big step forward from incandescent light bulbs, but eventually we will see them replaced with solid state lights and other new technologies that at the moment are still too expensive to compete for domestic lighting.

Top 10 employers list, made in Japan

A recent survey amongst Japanese third year university students indicates that relatively few aim to join the well known companies producing the export products “made in Japan” that, economically speaking, put the country on the world map during the 20th century.

According to the list published in Nihon Keizai Shimbun (2009-02-23), five of the top ten companies that students would like to work for were banks or insurances. There were also one airline (All Nippon Airways, #3), one travel agency (JTB, #5) and two railway companies.

Only one electronics company made it into the top ten (Panasonic at #4, unchanged from 2008) and no car manufacturer at all. The ranking clearly reflects the hit that Japan’s export industries have taken during the global economic downturn. Industrial icons such as Toyota (#46), Honda (#60), Sony (#22), Sharp (#37) dropped sharply from last year’s survey, when three of these were in the top 10 – Toyota (#3), Sony (#5) and Sharp (#6) while Honda at least made #22 then.

As an engineer I may be a bit biased, but I can’t help feeling sad when companies that make stuff for customers worldwide are seen as less interesting to work for than companies that domestically move money around.

Japan depends almost entirely on imports for primary energy resources and domestically produces little more than one third of the food that the Japanese eat. It will always have to depend on exports to pay for vital imports. The more bright minds that concentrate on competing globally, the better for the country.

The “new shopping new life” spam

For about a year I have been receiving spam emails like this one below. They all look like they’ve been sent by private individuals somewhere in the world (usually from Yahoo or Hotmail accounts) but advertise companies in China:

hi:
New shopping new life!
How are u doing these days?Yesterday I found a web of a large trading company from china,which is an agent of all the well-known digital product factories,and facing to both wholesalers,retailsalers,and personal customer all over the world. They export all kinds of digital products and offer most competitive and reasonable price and high quality goods for our clients,so i think we you make a big profit if we do business with them.And they promise they will provide the best after-sales-service.In my opinion we can make a trial order to test that.
Look forward to your early reply!

What appears to have happened is that spammers know the passwords to these mail accounts and are using them to send that spam to everyone in the mail account’s address book.

This is a very effective way to get through spam filters, as many recipients are likely to also have the sender in their address book and address book entries are automatically whitelisted by many spamfilters.

If you receive an email like that, alert the “sender” that their account has been compromised. They need to immediately change their email password to something more secure.

This abuse of stolen passwords illustrates the potential of password harvesting scams such as this one I documented in August 2008, which is still going on.

Here are some Google searches related to the hacked webmail spam:

Here is a (probably incomplete) list of websites advertised this way:

  • gvccn.com
  • ibvcn.com
  • jvccn.com
  • tvtcn.com

  • wabada.com
  • bj-trade.com
  • store-168.com
  • ele-motors.com

Good passwords and bad passwords

A strong password should be the first line of defense against such criminals, but what makes a password good? It should contain a mixture of all of the following:

  • lower case letters
  • upper case letters
  • digits
  • at least one non-alphanumeric character

This makes it hard to break the password through brute force or through dictionary attacks.

Also the password should not be too short (8 characters or more) and should be reasonably easy to memorize, so you don’t have much need to write it down. Some examples:

  • 45Knife%Cabbage
  • 4F5g6H&j
  • J0hn1945-07-31

Bad choices are passwords that consist of any word found in a dictionary, proper names, digits-only dates, adjacent keys on the keyboard or repeated characters. Never use anything like these:

  • secret
  • qwerty
  • xxxx
  • john45

It is very important not to use the exact same password for different purposes.

If spammers manage to trick you into revealing your password for one site (e.g. by getting you to create a new account at a site they control or by breaking into the database of another site where you’re a customer) then you’ve effectively handed them the key to the candy store. They can get access to your email account, in which they may find login information, password reminders, etc. of many other sites you’ve signed up for. At the very least they can harvest all your email contacts.

Beyond using different passwords for every site and service, it’s also a good idea to use a different password schema for “core” sites that you trust and depend upon (such as your email provider and webhost) and another for sites to which you sign up more casually (such as various forums, online shopping, etc.). Thus if one of the latter is compromised, it does not give criminals any clues what your more critical passwords may look like.

Who is behind this spam?

The sites advertised from the hacked email accounts constantly vary. They usually have been created only a few weeks or months earlier. For example, the domain in the above example was created two months ago:

Considering the highly illegal way the companies advertised, what are the chances that any order you make at those sites would ever get shipped to you? For sure, they will gladly take your cash by (untraceable, unsafe) Western Union or take your credit card number, expiration date and security code. Never use Western Union to send money to people you don’t know from real life in person. Never enter your credit card on a site that doesn’t have SSL access (indicated by a URL starting with https:// and a padlock icon in the browser status bar) with a proper certificate.

Even more basic: Never do business with spammers. By sending you spam, they have already proven to you that they lack any morals. You have no reason to trust them and every reason to be alert!

If you have received similar spams, feel free to post them below.

“Please respond or Some Stranger will think you said no :(“

I never really got used to the idea of MySpace “friends” and Facebook “friends”, a concept that seems to appeal mostly to teenagers seeking peer-approval. Friends are not objects you collect like others collect postal stamps or or sports memorabilia. Real friends are there for each other when we need someone. With my friends, years may pass without us meeting, but when we see each other again we pick up just like we last saw each other only yesterday. I know them and they know me and we don’t have to explain much. I would never think of showing them off on a website like others show off their gold chains and SUV to boost their self image. This is not at all what friendship is about.

For over two years I’ve been receiving emails coaxing me to join a website called tagged.com, supposedly sent by people who consider me their “friend”, but who I invariably do not recognize. I suppose they have my email address in their address book because they probably reported Nigerian scams to me before (I collect several hundred reports per day, most of which get processed automatically), but I could not possibly have had a two way email exchange with more than a small fraction of them, let alone built a friendship.

Here is a typical example:

Firstname has added you as a friend on Tagged.

Is Firstname your friend?

[ Yes] [ No ]

Please respond or Firstname may think you said no ๐Ÿ™

Click here to unsubscribe from Tagged, P.O. Box 193152 San Francisco, CA 94119-3152

Invitation spam

The tagged.com mails are just one example of a category of what I consider invitation spam, because they server no real purpose other than getting me to join a website that I have no interest in joining. The supposed sender already has my address and can contact me any time if he has something to tell me and if we really were friends, chances are I would already have his email too.

What I find particularly annoying about the Tagged.com emails is how they try to pressure the recipient into clicking the “Yes” link by exploiting people’s considerate nature. Most of us don’t unnecessarily want to hurt other people’s feelings. Therefore this line gets really on my nerves:

Please respond or Firstname may think you said no ๐Ÿ™

Interestingly, the same annoying phrase (either including the colon, left bracket frowning negative smiley or a positive smiley) started appearing in several other invitation spams that don’t mention Tagged.com:

From imvu.com, August 2007:

Hey Joewein,

To this day I am receiving a mix of Tagged.com, MyYearbook, Yaari and IMVU emails from various people.

The only party who really gets anything out of this type of (probably automated) email is the website owner. It actually doesn’t matter whether you click “Yes” or “No” on those spams, either way you’ll end up on a web form to provide personal details to join the site.

Many social networking sites ask for access to your Yahoo, Hotmail, Outlook or other address book when joining. They then send everyone in your address book invitations in your name. Thus the game continues as long as address books aren’t empty and at least some people click on either “Yes” or “No”.

When I receive such emails, I usually archive them to a folder in my mail cabinet that I named “Plaxo-Ringo” after the first two websites that spammed me like that in significant volume. I archive them for research purposes, but if you’re not a spam researcher like me you might as well delete them.

Just like on Facebook and MySpace I never act on “friend” invitations unless I have a genuine personal relationship with the sender, and neither should you. There is no need to feel guilty about discarding spam that is meant to sell commercial websites, even if it masquerades as something much more personal and precious, like friendship.

Windows 7 versus Linux on netbooks

“Does Linux stand a chance now that Windows 7 will run on netbooks?”, Shane O’Neill asks in an article in ComputerWorld on 15 January 2009 that overall sounds fairly optimistic on Microsoft’s prospects. However it largely avoids one crucial subject that matters for Microsoft in the struggle over market share in the booming nettop market: Money.

In 1985 Jack Tramiel, head of Atari Corporation came to visit Digital Research Inc. (DRI) to license its GEM graphical desktop environment for the new Atari 520ST. It was going to be a low-cost machine based on the same Motoroloa 68K CPU as Apple’s much more expensive Macintosh, which itself was a low-cost derivative of the Apple Lisa (that was long before Microsoft Windows became a viable product). Tramiel had a reputation as a fierce negotiator, so his counterpart at DRI, then the main competitor of Microsoft and Apple, was only half joking when he said to Tramiel: “Jack, I know you’ll probably start off by offering us a dollar per copy.” – “No,” replied Tramiel dryly. “50 cents.”

Tramiel knew that by coming out with a fully-functional product at rock-bottom prices he could grow the PC market. In the segment he envisaged there simply was no margin for a $50 operating system license. What was true when an Atari machine cost around $1000 is even more true today with $250-$450 netbooks, and future netbooks will be even cheaper than that. Soon we will also see netbooks based on the same low-power, low-cost ARM processors that power virtually all mobile phones.

Commentators cited by Computerworld on Windows 7 don’t really talk about money:

Analyst Rob Enderle, president of technology research firm The Enderle Group, agrees that Microsoft doesn’t see Linux as much of a threat and that refocusing on the netbook market is more about “Microsoft addressing the problem of having to keep shipping Windows XP long after its expiration date.”

Enderle says that getting XP on netbooks was clearly a response to Linux gaining traction, but that Microsoft is not afraid of consumers or OEMs having a preference for Linux.

“The problem was that Linux could run on a netbook and Vista couldn’t, not any consumer or OEM love for Linux,” he adds.

But Microsoft’s real problem wasn’t just that Vista was too big to fit on a 4 GB flash drive and too slow and bulky to run on an Intel Atom with 512 MB of RAM. It was also too expensive. So Microsoft could save face by charging next to nothing for its 5 year old Windows XP, but it didn’t make any real money on it. So what’s going to happen when Windows Vista 1.1 aka Windows 7 hits the streets in volume maybe a year from now?

Does it really matter to Microsoft shareholders and employees if the 21 million or so netbooks expected to be sold this year (and the even bigger numbers in 2010) will be running some version of Windows or a version of Linux (which is free), if previously those buyers would have picked up a more powerful machine that netted Microsoft $40-$100 per license?

Whether Windows 7 will run with decent performance on low-cost machines is really only half the question. The other is, how much Asus, Acer and the other netbook OEMs will offer to pay Steve Ballmer of Microsoft. Is it going to be $1 or 50c per copy? That is no way to sustain a business with a market capitalization of $150 billion and almost 90,000 employees worldwide (Jan 2009 numbers), as Microsoft is realizing to its horror.

Google Groups spam – abuse reporting broken

You can tell that an anti-spam tool is becoming too effective when spammers start trying to work around it.

Such is the case with Spam URL Blacklists (SURBLs), which list domains advertised via spam. Spamfilters will intercept emails that mention blacklisted domains used in clickable links. The spammers can use fake sender addresses and send email from cracked hosts and cracked third party mail accounts, but they still get caught as soon as they mention their websites. This hurts spammers because they only make money when people go to their websites and hand over their credit card details to order fake Rolexes, pills, porn, etc.

To get around this, spammers have been using pages created at free webhosting services and other third party sites where content can be uploaded. The links only mention the free hosting site, which then redirects to the final spam site.

One service abused for this is Google Groups. Other services recently seen used are Google Docs, Microsoft Spaces Live and Geocities. In the case of Google Groups the spammers create mailing lists and upload a spam link to the home page of the new group. They never use the groups for their intended purpose, i.e. mailing lists. This effectively makes it impossible to report the abuse via Google’s abuse handling procedures: Any archived posting or uploaded document on the Google Groups service has an abuse reporting link, but the home page of the group itself does not! Obviously, Google never envisaged that spammers would create groups only to have one page of web content that can be advertised via spam.

Here is an example of a spam:

(Add S+H)

The page advertises “Click Here – Free Credit Score & Debt Help” which is a spam link using the domain white-teeth2009.com hosted on IP address 220.164.144.205 in China. It is listed on four sub-lists of SURBL (WS, OB, AB and JP). Its name servers are ns1.dckfdc.com and ns2.dckfdc.com. Other domains by the same spammers are whiten-your-smile2009.com and smile-really-great.com.

At the very least Google should add an abuse reporting link to its Google Group pages. It would be even better if they were to check uploaded Google Group content and checked any URLs in it against spam blacklists such as SURBL. This would stop the spammers in their tracks.

What’s that “Yanga WorldSearch Bot v1.1/beta”?

A few days ago I received email alerts notifying me of abnormally high web server traffic. Naturally my first thought was that this might be a Denial of Service attack (DoS): My sites have been attacked before, including by botnets consisting of several thousand rogue computers. This time, during a one hour period, traffic exceeded the same period one week earlier by 800 MB, which works out as 20 GB per day if sustained.

A search of the server logs showed numerous requests like the following, requesting up to 50-60 documents per second:

91.205.124.4 – – [09/Jan/2009:19:20:39 +0000]
“GET /emails/2008-06/30/00209262.117.htm HTTP/1.1” 200 12928 “-”
“Yanga WorldSearch Bot v1.1/beta (http://www.yanga.co.uk/)”

All originated from the same IP address in Russia (91.205.124.4) owned by Gigabase Ltd in Moscow. I found it very odd that this search bot listed the URL of a commercial UK website as its reference, but the company that operates the service does so from Russia. A visit to yanga.co.uk yielded little information – the UK website turned out to be little more than a placeholder page, with no UK street address and only a non-geographic phone number. I grew very suspicious at this stage.

A Google search found a thread on Webmasterworld.com in which “Alexey”, who introduced himself as the CEO of Yanga, responded to criticism. He didn’t give his last name, but perhaps he is Alexey Tarasov who is listed in the Gigabase Ltd WHOIS record.

While it is good to see that Yanga WorldSearch / Gigabase are concerned enough about their reputation to respond to public criticism, they would do well to take steps to raise fewer suspicions in the first place. They could definitely be more open about their identity and their purpose, as well as trying be a good citizen when visiting other people’s websites (e.g. complying with robots.txt, sticking to reasonable traffic levels). Trust is social capital that is hard to earn but quick to burn. No business can succeed on the web without it.

USB turntables: Sony PS-LX300USB

This week I bought myself a late Christmas present, a Sony PS-LX300USB turntable and there is a story behind that. I have a fairly large LP collection which I acquired mostly in the 1980s, mainly reggae and African music. Most of the about 450 LPs I found in record stores in the UK, others were bought in Harare, Zimbabwe or in Germany.

My friends in Zimbabwe used to joke that I had more Zimbabwean music than was available locally. It was half true: When I went record-shopping in Harare back in 1988/89, I found that the predominant type of music available was Country & Western, because that’s what sold best amongst white Rhodesians who had the money.

Paul Simon’s Graceland album brought Southern African music to a wider audience, but when most consumers in rich countries switched from LPs to CDs in the late 1980s and 1990s, African artists and their music were left behind again. Much of what I bought then never made it onto CD and is unavailable today.

One of my long term projects therefore was to archive my vinyl collection onto hard disk, to keep it from disappearing altogether. Recently, I wanted to continue with that after a pause of about two years, but my trusty old Dual CS-503-1 which I had bought around 1987 had stopped working due to a broken drive belt. Even after I installed a mail-ordered replacement belt it didn’t sound right.

Then I started thinking about USB-enabled LP players. There are models that will record directly onto a USB thumbdrive, but I was more interested in USB turntables that can be connected to a PC using a USB cable because they offer much more control over the recording process. The host operating system sees them as a line input on a sound card. You can record 44.1 KHz 16-bit stereo samples just right for burning a CD, or you can compress to MP3 after whatever editing and digital cleanup you fancy.

I can say that I am quite happy with the sound quality of the PS-LX300USB. There are other USB turntables that are cheaper, but I did not want to get the cheapest player that does the job. I won’t have the time to digitize my large collection twice. Having said that, my old Dual probably was a better player than the Sony. It has an adjustable anti-skating weight on its tone arm and its wow and signal-to-noise values look better on the spec sheet. On the other hand the Sony has start and stop buttons (the Dual’s mechanical controls are more basic), but more importantly the A/D-converter is built into the turntable (along with a pre-amplifier). With the analog Dual I had to use a sound card to digitize the analog line input coming from an amplifier hooked up to the phono output of the turntable. There is bound to be more interference inside a PC and most PC sound cards are cheaply made. Analog cables can pick up some noise too. That’s what makes USB turntables a worthy consideration, apart from the ease of use.

The mechanical setup wasn’t too difficult. I ignored the bundled Audio Studio LE and instead downloaded open-source Audacity off the net, which is working fine for me.

On the first evening after I unpacked the turntable and set it up, my 13-year old daughter looked at the spinning vinyl disk, which she had never seen in action. We listened to old favourites of my wife and me and it brought back many memories. Now I will be able to enjoy those tunes in the car or anywhere away from home, after I gradually record them one by one off a now largely obsolete medium.

Skype Auto-Recharge and currency changes

Checking my PayPal details today, I found that three of my most recent payments for Skype involved a dollar to euro conversion. This surprized me, since quite a while ago I had changed the currency of my Skype account from euros to dollars to match the currency of my PayPal account, in order to avoid conversion losses.

When I went to my Skype account I found that my currency indeed was set to dollars, however the recharge amount was set to €10. Auto-recharge is a convenient feature. With it turned on, whenever your account credit balance drops below $2, an automatic purchase using your credit card or PayPal account takes place to top it up again. As I use SkypeOut for all my international phone calls to landlines and mobile phones and also occasionally for call-forwarding from a SkypeIn number to my mobile phone (especially when I’m travelling), it helps me never to run out of Skype credit.

Evidently, changing your Skype currency does not change your account recharge currency (or amount). What’s more, the system would only let me pick a recharge amount of €10 or €25.

The only way to switch recharges from euros to dollars is to cancel auto-recharges and then re-enable them. However, the only way to enable recharging appears to be by topping up your balance – you’ll have to spend some money!

Thus if you have changed your Skype currency from euros to dollars and want to use auto-recharge in the new currency, you will first have to cancel the recharge and then buy another $10 worth of Skype credit, with the “enable auto-recharge” option checked.
