If your preferred TLD domain name has been taken by a rival then it is clearly still worth using a different TLD particularly your own regional one.

Duplicate domains

Be careful of having duplicate content on different domain names, as this is seen as “spamming” by Google and can lead you to being penalised or even banned on Google.

Google’s quality guidelines specifically state – Don’t create multiple pages, sub-domains, or domains with substantially duplicate content.

You can however register multiple domain names and use a 301 redirect. Such redirects are recognised as being completely valid.

Protecting your Brand

If you are building a brand it is often good practice to purchase all TLD’s for your name, once a domain name is registered it can’t be transferred without your permission. If you add web-forwarding to each one of domain names other than your main site then what ever your customers enters as a TLD they will still find you.

This will also help to protect you against unscrupulous rivals who may register a domain name with intention of capturing traffic from your site.

But is that BEST? That depends upon your processor.

Every time you add something to a logarithm it is like multiplying antilogarithm. Some processors will multiply quickly, others not. So trick of SHIFTING a number is a good substitute for multiplication. Copy number. Shift it right. Add number you first thought of. You have multiplied by ONE-AND-A-HALF without multiplying.

So you can create table of logarithms of one-and-a-half, one-and-a-quarter, one-and-an-eighth and so on. From these you can build an antilogarithm algorithm that differs from McLaurin-Taylor.

And what happens when number of shifts exceeds half number of bits in mathematics? Eureka! an unexpected move! Check Mate.

The program has terminated in only a quarter of expected time!

Books have been written about chess. Rather fewer have been written about transcendental machine-code mathematics. These things are commercial. They are closely-guarded trade secrets.

I had spent some years developing most exquisite tricks, and was prepared to write definitive manual on subject. However, British government stole everything from me - leaving me only with memory of many an elegant "game".

What should I do? Should I continue to hide my knowledge? No. I hastily put down in writing as many salient points as I could remember. Perforce, these are just summaries of techniques involved. There was no time to dwell upon detail. However, those who need to know reasoning behind inner core of floating point, and have time to delve and ponder, may well find this page to be a treasure-trove of programming ideas.
