The Last Question by Isaac Asimov © 1956
The last question was asked for the first time, half in jest, on May 21, 2061, at a time when humanity first stepped into the light. The question came about as a result of a five dollar bet over highballs, and it happened this way:
Alexander Adell and Bertram Lupov were two of the faithful attendants of Multivac. As well as any human beings could, they knew what lay behind the cold, clicking, flashing face -- miles and miles of face -- of that giant computer. They had at least a vague notion of the general plan of relays and circuits that had long since grown past the point where any single human could possibly have a firm grasp of the whole.
Multivac was self-adjusting and self-correcting. It had to be, for nothing human could adjust and correct it quickly enough or even adequately enough -- so Adell and Lupov attended the monstrous giant only lightly and superficially, yet as well as any men could. They fed it data, adjusted questions to its needs and translated t

Vowel qualities in English words
The following is a list of the most common one-syllable words in English, grouped according to what vowels they contain. You will need to memorize the pronunciation of all these words for the final exam. Luckily, in most cases the spelling will help you. I suggest that you create a guide for yourself noting how particular letter combinations are usually pronounced, and which words are exceptions. The words have been arranged in groups according to spelling. (This list is a slightly modified version of one created by John Myhill.)
I have used the following substitutes for phonetic characters (see your handout from the IPA Handbook): [E] for the vowel in 'bed', [I] 'bid', [U] 'good', [A] 'bad', [^] 'bud', [O] 'bought', [3] RP 'bird', [@] for schwa.
Words pronounced with the near-high near-front vowel [I]:

How to install GNU gettext on MAC OSX
View gist:1647940
  1. Wget
  2. Untar file as tar -zxvf gettext-0.12.1.tar.gz
  3. cd to the directory containing the package's source code and type ./configure to configure the package for your system. If you're using csh on an old version of System V, you might need to type sh ./configure instead to prevent csh from trying to execute configure itself.

Running configure takes awhile. While running, it prints some messages telling which features it is checking for.

  1. Type make to compile the package.
  2. Optionally, type make check to run any self-tests that come with the package.
  3. Type make install to install the programs and any data files and documentation.
