What Is The Point Of An Auto Navigation System?

November 23, 2011 By Leave a Comment

Maps are essentially defective. By the time the surveyors have finished and the data that they have collected has been mapped out and the printers have published the map and sent it to the distributors and they have sold it to the shops and you have made up your mind to buy one, it is out of date. Sometimes years out of date

Another problem is that it is impossible to read a map and drive carefully at the same time. You cannot read a map and look out of the windscreen at the same time. So, you either need a co-pilot who can read a map, or you have to stop often and memorize a small part of the map. That is all right, travellers did it that way for a hundred years or more, but now there is a better way.

GPS satellite navigation devices have been around for a long time. At first they were only used by aircraft and ocean liners. As the price fell, yachting people could afford them; later still long distance lorries had them, then very expensive cars and now practically all vehicles.

Despite the odd story of someone driving into a river in the dark, because the driver trusted the sat nav and the sat nav did not know that the bridge had been removed, the auto navigation system has been a resounding success.

I am certain that family Sunday outings are far more pleasurable now that the spouse does not have to do the map-reading; lone travellers do not have to stop to get their bearings and lone female drivers are safer because they do not have to stop to ask directions.

Being lost at night or having broken down in the countryside or even taking a wrong turn into a rough district of town is terrifying. Even if you have your cell phone to call the breakdown service, you have to know where you are and if you are in a rough area of town by mistake, you do not want to stop to ask the way and you certainly do not want to go farther off the beaten track.

Then there are the detours that we want or have to make because of natural catastrophes, break-downs, traffic jams and roadworks teams. Sometimes you will get advanced warning on the local radio of trouble spots up ahead, but if you do not know the area, there is not much you can do about it. Unless you have an auto navigation system.

I know many people who do not use their auto navigation system every time they get into their car and that is how it ought to be for those people, but it is like insurance, it is nice to have it when you need it.

No-one has to have an auto navigation system to go to the local supermarket, but it is really nice to take the scenic route the next time you go out of town to visit a relation. Perhaps you always take the same route when you visit your Aunty Lil, but with an auto navigation system you can vary your trip to pass local attractions.

Advice For Avoiding Mosquito Bites

November 20, 2011 By Leave a Comment

So, you have got some time off work, university or school and you want to sit outdoors and relax. Possibly even go on holiday somewhere.

What a great idea! However what happens after you arrive at where you are going? The mosquitoes come out to get you.

If it were not so everyday, it would sound like Freddy Kruger and Nightmare on Elm Street. The female mosquitoes want blood to create eggs and they seek it out as avidly as any vampire in a horror film, whereas the males go sucking nectar from plants like bees.

Well, that is the nightmare setting, but it is not that far from the truth either. For lots of nations in the world it is also a real life and death issue. Millions of people die each year from malaria and tons more from dengue as well.

Yet both of these illnesses are curable as are most of the other mosquito-borne illnesses like Yellow Fever, Japanese Jungle Encephalopathy and West Nile fever.

The first thing to understand is that typically these diseases can be injected against, particularly if you are going on holiday. The next thing to keep in mind – it may help – is that not all mosquitoes are the same.

For instance, in Thailand, the dengue-bearing mosquito (frequently known as the ‘Egyptian’ mosquito) comes out at dawn and dusk and so bites then too. Between around an hour before and after dawn and an hour before and after dusk, whereas the malaria-carrying mosquito, the Anopheles, is a night time huntress.

I am not suggesting that you can slacken your guard during the day, although lots of people take for granted that they can. Nobody wants dengue fever either.

So, what should you do? Before you go anywhere, read up on the area or check with medical experts. That part is not difficult, especially, if you know how to search the Internet.

Then prepare yourself with inoculations if the danger is serious enough in your opinion or a medical expert’s opinion. In my estimation, that is the minimum that a conscientious person ought to be expected to do to protect him or herself, the family and the community in general.

Then there are a few other things you can do. For example, wear baggy clothes, but long sleeves and long trousers. If you are thin on top by choice or not, put on a hat or cap.

Wear socks or stockings in the evening to safeguard your feet. Buy a good-quality mosquito repellent and rub it on your exposed skin, as often as recommended by the manufacturer, which is typically every four or five hours.

You could rationally stop at that point, but I like to go a bit further, if the circumstance calls for it. If I am outdoors in the garden at home or in a hotel, I like to have one of those tennis racquet style electric bug zappers with me. They are fantastic for zapping the odd mosquito that irritates you.

They are good for clearing the bedroom before retiring too and lastly, if I am renting, walking, camping or caravaning, I may find space for a rechargeable lantern-style bug zapper too.

If the little so-and-sos are going to give me a fever, they are going to have to work very hard to do it.

Who Or What Is A Personal Digital Assistant?

November 15, 2011 By Leave a Comment

A personal digital assistant or PDA is an electronic item somewhat similar to a regular laptop computer, but smaller, normally the size of a book or magazine. They are like diaries or organizers but far more capable. They may be Wi-Fi-enabled in order to send and receive files, send and receive email and go on the Internet.

in fact, not all PDA’s are exactly the same size or have the same features, but they are all quite similar. People use them for taking notes, recording lectures, doing homework, composing articles and reminding themselves of appointments among a hundred and one other jobs. The PDA is the tool of preference for people leading a busy career.

Some PDA’s have full Net access and others will permit you to connect to a laptop or desktop computer in order to download or upload files for processing later. With these machines, you can download all your email, for instance, process it on the bus or the train on the way to the office and then plug your PDA into your office computer to send them once you arrive in the office.

More sophisticated PDA’s will also connect to your office and home computers, but will actually go on the Net themselves. This means that you ought to synchronize your home and office computers with your PDA so that all your files and computers have the same copies of all your data. MS Windows has been using this notion for many years and called it ‘Briefcase’.

The electronic briefcase is now reality and has been for a time. In fact, the laptop was the original PDA and what you can buy now as a PDA is a cut-down version of the laptop-cum-notebook computer.

Some PDA’s are really like notebooks in that you are able to write on the touch sensitive screen. A software program can read your handwriting, after being taught it, and convert it into typed text.

It can also convert typed text into your handwriting. Setting this feature of the PDA up may be quite tedious though with numerous errors taking place in the early days.

The PDA is like a desktop with all the devices that you would expect to find there and near it, like a pen and pad, a calculator, a diary, a to-do-list, a calendar, a phone book, an address book and even a cell phone or even VOIP, if it is connected to the Net. Apart from these ‘physical’ desktop items, the PDA will almost certainly have a database and the capability to read ebooks.

Some PDA’s will also record voice messages, take photos and even read ebooks and messages back to you. A PDA is a most helpful device if you have need of one.

They are handier than a laptop and lighter. They are not a substitute for a computer but rather should be regarded as an accessory to a computer to save you lugging the computer about.
