What is the longest river in the world?

The Nile River, which flows through eastern Africa, is generally considered the longest river in the world.  There is some debate, however, on this topic.  Some researchers say that the Amazon is the longest river in the world.


The source of the Nile River is Lake Victoria in Tanzania.  The river flows north for over 4,000 miles through many East African countries.  The country that is usually associated with the Nile River is Egypt.  Ancient Egyptians relied heavily on the Nile River for defense, agriculture, and trade.  The Nile River is still important today for the agriculture of the countries it flows through.


The Amazon River is also over 4,000 miles long. It flows through many countries in South America.  Scientists studying the Amazon River have debated about its source.  Recent studies state that the source of the Amazon River is the Mantaro River in Peru.

Is there a word/phrase for "unperformant"?

As a software engineer, I need to sometimes describe a piece of code as something that lacks performance or was not written with performance in mind. Example: This kind of coding style leads to unmaintainable and unperformant code. Based on my Google searches, this isn't a real word. What is the correct way to describe this? EDIT My usage of "performance" here is in regard to speed and efficiency. For example, the better the performance of code the faster the application runs. My question and example target the negative definition, which is in reference to preventing inefficient coding practices. Answer This kind of coding style leads to unmaintainable and unperformant code. In my opinion, reads more easily as: This coding style leads to unmaintainable and poorly performing code. The key to well-written documentation and reports lies in ease of understanding. Adding poorly understood words such as performant decreases that ease. In addressing the use of such a poorly ...

Is 'efficate' a word in English?

I routinely hear the word "efficate" being used. For example, "The most powerful way to efficate a change in the system is to participate." I do not find entries for this word in common English dictionaries, but I do not have an unabridged dictionary. I have checked the OED (I'm not sure if it is considered unabridged), and it has no entry for "efficate". It does have an entry for "efficiate", which is used in the same way. Wordnik has an entry for "efficate" with over 1800 hits, thus providing some evidence for the frequency of use. I personally like the word and find the meaning very clear and obvious when others use it. If it's not currently an "officially documented" word, perhaps its continued use will result in it being better documented.
