this general software engineering principle question.

i have tab-separated log file lines that: event_a info1 info2 event_b info1 info4 event_c info2 info5 ... i want convert csv (with python) column has meaning. info1 e.g. id, info2 desintation, info4 coordinate etc. i can "sloppy" way: if "event_a" in line: columns = line.split() id = columns[1] i prefer have lookup matrix or table structure this, positions columns separated programming logic. there allows me define expressive overview here, code like: for line in csvfile: matches = event_table.match(line) match in matches: event_table.convert(match) # add commas in between values account empty columns i of course create class per event, seems overkill. looking central definition, can use. the output is: event_a, info1 info2 event_b, info1, , , info4 event_b, , info2, , , info5 ... event_365, , , , , , , , , , , , info12 edit: log file contains 100s of such event types, make code rather long , hard maintain d...

i have used double.doubletorawlongbits , long.tobinarystring convert double value string of bits . however, trying find methods convert string of bits double . double.longbitstodouble convert long representation of bits double , have been having trouble finding method convert string of bits long representation of bits . any question appreciated! thank time in reading this. given long n = ... string s = long.tobinarystring(n); you use long reconstructed = long.parselong(s, 2); to reconstruct long.

right have started develop small project, extend knowledge of web-app aspects , realise idea got last monday. so, i've got nodejs + mongo. project fun&education don't care performance etc, try new. mowing problem: i've got structured data, stored plain text file. after dancing around wrote script, convert datas objects (custom objects) , pushed them mongodb. problem is: after them db - plain objects. i'm lacking of sweet , great setters, getters etc. after thinking while found 1 possibility, how it: run through whole response array, , add .prototype functionality need (setters, getters, etc). seems have poor performance , approach seems silly. i ask you, right way so? example when use google apis - got custom objects, bunch of useful methods. other example - during summer working on project based on symfony2, i've used strange (in moment) doctrine2 orm layer. in oop world found awesome. same trick under hood - convert query result objects , returns them ...

(sas studio / sas enterprise miner on demand -- web access school.) i uploaded , imported .csv file sas studio. import function let me select libraries webwork , work (temporary), not viewable sas em. import created webwork.input , "/home/my_username/.sasstudio/webwork/rs2999/import.sas7bdat. how move "../import.sas7bdat" file "/home/my_username/my_content/(etc)" can see sas em? (i can upload .sas7bdat files directly need them sas studio, , that's uploaded .csv file.) thanks you need base sas library in studio , sas em pointing same location. since in home directory metadata library overkill. recommend using libraries tab in studio , creating library "/home/my_username/my_content/(etc)" , in em open explorer ( view - explorer) , create library same location. not have have same name, best practice so.
