4/9 'Government probes case of texting helicopter pilot' http://www.csua.org/u/zsc (news.yahoo.com) 'The pilot ... exchanged 20 text messages, over a span of less than two hours preceding the helicopter crashed ... Most of the messaging was with an off-duty female co-worker with whom he had a "long history" of "frequent, intensive communications," and with whom he was planning to have dinner that night ..." Texting kills. Mistress kills. |

4/8 Margaret Thatcher, Annette Funicello, who's next? They always die in threes. \_ Yeah. Michael Jackson and Farrah Fawcett died on the same day also. I still recall that when I was driving in the afternoon that day, KCSM was playing Dave Brubeck sound tracks non-stop for half an hour without the DJ saying anything. So I thought Brubeck died on that day too. \_ Robert Edwards is number three. Really strange. \_ YOU. |

4/8 What's a good free e-mail provider? I don't want to use Gmail, Yahoo, Outlook, or any of those sites with features I never use that track my personal info and keep changing their interface. I want just simple e-mail without privacy issues or all the baggage these large, for-profit companies are adding. I might even be willing to pay. Recommendations? \_ http://well.com. Not free though. http://www.well.com/mail.html \_ soda has been very consistent for the past few decades, why don't you use soda? \_ I thought soda stopped hosting mail years ago. -- !OP \_ http://mailinator.com -- completely insecure, but great for throwaway email accounts. |

4/04 Is there a good way to diff 2 files that consist of columns of floating point numbers, such that it only tells me if there's a difference if the numbers on a given line differ by at least a given ratio? Say, 1%? \_ Use Excel. 1. Open foo.txt in Excel. It should convert all numbers to cells in column A. 2. Open bar.txt in Excel. Ditto. 3. Create a new file in Excel. 4. In cell A1 of the new file, enter this: =IF(foo.txt!A1=0, IF(bar.txt!A1=0, "same", "different"), IF(ABS((b\ ar.txt!A1-foo.txt!A1)/foo.txt!A1)<1%, "same", "different")) 5. Select cell A1. Hit Ctrl-C to copy. 6. Select the same number of cells as the number of cells that exist in foo.txt or bar.txt. Hit Ctrl-V to paste. 7. Hit Ctrl-F. In "Find what:", enter "different". In "Look in:", choose "Values". Click "Find All". Another way is to write a C program to read the two files using fscanf("%f") an do the arithmatic. \_ does this help? #!/usr/bin/python import sys threshold = float(sys.argv[3] if len(sys.argv) > 3 else 0.0000001) list1 = [float(v) for v in open(sys.argv[1]).readlines()] list2 = [float(v) for v in open(sys.argv[2]).readlines()] line = 1 for v1, v2 in zip(list1, list2): if abs((v1 - v2) / v1) >= threshold: print "Line %d different (%f != %f)" % (line, v1, v2) line += 1 \_ Something like this might work ($t is your threshold): $ perl -e '$t = 0.1 ; while (<>) { chomp($_); ($i,$j) = split(/ \t/, $_); if ($i > ((1+$t)*$j) || $i < ((1-$t)*j)) { print "$_\n"; }}' < file |
