A surfeit of guineas

To the traveller and geography student alike it can be perplexing that a single name can be applied to multiple countries. On the one hand, North and South Korea have an easy to understand border. The adjacent South American countries of Guyana, French Guiana and Suriname (formerly Dutch Guiana) also make geographical sense. Even the two Congos seem appropriately positioned. But how do four countries, only two of which are adjacent, come to be named Guinea?

Guinea is the name given to the coastal areas of western Africa between the tropic of cancer and the equator. The word "guinea" is derived from a Berber word meaning "black man".

The area which was to become the country of Guinea was detached from Senegal in 1890. It became French Guinea in 1895, and with a referendum in 1958 became the independent country of Guinea.

In the 19th century the Portuguese had a base at Bissau, a city to the north of the aforementioned French area of Guinea. Including the surrounding area of influence this was known as Portuguese Guinea, until independence was declared in 1973 and its name changed to Guinea-Bissau.

Far to the south of the aforementioned guineas, just north of the equator, the Spanish had in some form been holding land since the 18th century. In the early twentieth century their local territories were united as Spanish Guinea. This became Equitorial Guinea in 1963 after some autonomy was given, and then it became fully independent in 1968.

The south Asian island of New Guinea was named in 1545 by Spaniard Ynigo Ortis de Retez, apparently due to the resemblance between the islands' inhabitants and those found on the African Guinea coast. The eastern half of the island was annexed by Indonesia in 1969. The western half, the country of Papua New Guinea, became independent from Australia in 1975.

Wake to internet streaming audio

When you've become jaded with the usual morning radio shows, being woken by streaming audio from the internet becomes an enticing option. If you have a laptop, or perhaps a PDA, with WiFi, then it shouldn't be too hard to leave that near your bed at night, and have it wake automatically and play some audio. But what if you only have a PC, and it's quite some distance from your bedroom?

It turns out to be quite straightforward. What you need to happen is:

  1. PC wakes automatically at pre-determined time
  2. PC plays streaming audio
  3. Audio gets transmitted on FM band
  4. Clock-radio turns on, and receives transmitted audio

Let's go through each step in detail.

Steps 1 & 2

The first two steps depend on what operating system you have installed. In Windows XP you can combine the waking up and the playing of audio into one scheduled task. In the control panel, I set up a scheduled task to run every day at 9am. My run command is to open my web browser to play BBC Radio 4 live - "D:\net\Mozilla Firefox\firefox.exe" "http://www.bbc.co.uk/radio/aod/radio4.shtml?listen".

Under 'settings' there's a power management option to 'Wake the computer to run this task'. This uses the wonders of ACPI to make the computer turn on at the right time, even if it's hibernated and turned off.

I had to do one additional thing to get this working. When Windows XP resumes from hibernation, the network is unavailable until some time after the desktop. So when I first tested out this scheduled task, I found that it would fail because the network was not ready in time. To get around this I set up a second scheduled task, simply opening 'notepad.exe', a minute earlier than the first. This meant that the network had time to prepare itself before the request to receive Radio 4 was made.

See footnote [2] for related information.

Step 3

To transmit this audio I used the FM transmitter that I built from a kit a year ago. An easier alternative would be to buy a ready-made transmitter, such as that from C.Crane. The numerous iPod and MP3 FM transmitters now available are only designed to broadcast over a small distance of a few metres, so they probably won't be suitable for this task.

To ensure that I didn't have to leave it transmitting all night, I used a cheap indoor timer, the type that magically keeps burglars from your house when you're on holiday. The clocks on these devices are pretty rough, but it doesn't need to be terribly accurate. It just needs to encompass the possible transmitting time, so a half-hour excess to each side is not a big problem.

Step 4

Finally, you need to set your clock-radio to the frequency that your transmitter is working at. Then you can test the whole system at some decent hour, and look forward to being pleasantly awoken by the sounds of your choice.

Notes

[1] The automatic power-on option in the BIOS of many motherboards will not work when you shut down using an ACPI-aware operating system, such as Windows XP. The OS takes control of the waking up, so you must use the OS to set when and how to wake up, such as using a scheduled task. This is certainly much easier than having to get into the BIOS whenever you need to make a change.

[2] My PC needed the power supply to remain on when hibernating for the wake up to occur. This is in contrast to normal hibernation, which is unaffected by the power being turned off. So, having your PC on an indoor timer will not work, though I'd still recommend that for the transmitter.

Famous, or rather infamous...

Many words have more than just a single meanings. The determination of the intended meaning from its context is a skill learnt early on in language development. For example, differentiating set as referring to a bone healing, as opposed to a film stage, is straightforward. However, when a word has two or more meanings which are similar enough to fit into the same context, then we can encounter problems.

The main meaning of famous is well-known, but it can also mean first-rate. Thus, if an unknown Harry Smith is described as famous, we can't rely on language structure forcing only one meaning to fit. Instead, we depend on other clues being given. For example, if he was only mentioned in a footnote as a famous author, we would have to assume one of the meanings. Alternatively, if he was described in a paragraph lauding his achievements, then the intended meaning would be obvious.

Infamous, literally not-famous has only the single definition, that of having a bad reputation. This allows the possibility that the description of famous and infamous can be applied to the same person. However, the strangeness of this mitigates its use. 'Adolf Hitler, famous and infamous leader ...' anyone?

[As a rather confusing aside, famous also has an archaic meaning of ill repute.]

Notorious is a good, solid synonym for infamous. However, it is also a synonym for widely known, or famous.

Known widely : famous, notorious
Known widely and esteemed : famous
Known widely and unfavorably: infamous, notorious

Now that that's all cleared up, you can get to see a whole world of confusion out in the real world. The first result on Google for "famous and infamous" is currently The Great, the Famous and the Infamous. Here, if famous meant 'known widely' then 'great' and 'infamous' are superfluous. If it meant 'known widely and esteemed', then 'great' is superfluous. Indeed, the whole first page of google results will give you a headache. Wasn't life simpler when you didn't think about this stuff?

Pricelessware 2005

If you've been checking the Pricelessware.org site for updates to their list of top freeware of 2004 then you've been missing out. For mysterious reasons that site has been abandoned, and its activity moved to Pricelesswarehome.org.

The 2005 list is available, though it is not as nicely formatted as the 2004 list. However, the all-important information is as reliable as ever.

Winning the wrong prize

Nestlé Australia is running an interesting competition to tie in with the Tim Burton Charlie and the Chocolate Factory movie:

Discover a Golden Ticket and win a trip for 2 adults and 2 kids (under 12) to the Nestlé Chocolate Factory in York, England!

There are only 5 tickets to be found throughout Australia. To instantly win a Golden Ticket prize, simply purchase any specially marked WONKA Whipple Scrumptious Caramel Delight Block or Bar and check inside the wrapper!

I wonder if they thought the winners wouldn't notice, or wouldn't mind, that they were being taken to the wrong factory. I guess the problem is that the factory that was Dahl's inspiration, in the suburb of Bournville in Birmingham, is owned by Cadbury. I grew up near Bournville, so I feel obliged to be a little protective of its reputation.
