i generating images of webpages urls , writing them local filesystem, , want name image url. however, if this, since there / 's in url, create new directories instead of calling image entire url. there way avoid this? i don't believe it's possible place / or \ in file name. best thing can think recommend replacing / or \ alternate characters not found in urls, such $ ^ , !. if can't find single character replace slash, can use short string that's unlikely in url, such [slash] or combination of symbols. the problem watch out when using short string length of file names. although oses won't have problem, may not able zip them full name.

i using sas's file statement output text file having fixed format (recfm=f). each row end in end-of-line control character(s) such linefeed/carriage return. tried file statement's option termstr=crlf still see no end-of-line control characters in output file. think use put statement insert desired linefeed , carriage return control characters, prefer cleaner method. reasonable thing expect of file statement? (is reasonable expectation outputting fixed format data?) (platform: windows v6.1.7600, sas windows v9.2 ts level 2m3 w32_vspro platform) do need use recfm=f ? can still fixed length output v : data _null_; file 'c:\temp\test.txt' lrecl=12 recfm=v; i=1 5; x=rannor(123); put @1 @4 x 6.4; end; run; by specifying want data go ( @1 , @3 ) , format ( 6.4 ) along lrecl fixed length output. there may work-around, believe sas won't output line-ending fixed format.

i started coding rpg engine in python , want scripted(buffs, events). experimenting events , hooking. appreciate if tell me matured opensource projects(so can inspect code) learn from. not python, ideal. thanks in advance. as daenyth suggested, pygame great place start. there plenty of projects linked on page. the other library quite lovely type of thing panda3d. though haven't yet used it, library comes samples, , looks there list of projects using somewhere. have fun.

i profiling programs using "time" command on linux. outputted results in format this: 1m48.952s now tabulate , graph collected data it's not easy when it's in format. i have 2 questions: 1. there way convert format solely pure seconds. perhaps openoffice calc function? 2. there way call "time" command output in seconds , not minutes-seconds. thank much well tagged excel, here's excel solution: =if(iserror(find("m",a1)),value(left(a1,find("s",a1)-1)), left(a1,find("m",a1)-1)*60+mid(a1,find("m",a1)+1,find("s",a1)-find("m",a1)-1)) it's simple formula translate directly open office. here's sample results: as second question, man time explains can -f format output. description of how set format string in link. believe want -f %e elapsed real time (in seconds). default appears %e elapsed real time (in [hours:]minutes:seconds).

is there established "best practice" handling external dependencies in tfs working branches? mean is, have project in tfs contains common third-party libraries (in case i'm dealing log4net), branch our other projects needed. we're making significant change i'm doing on separate working branch, requires newer version of component. looks this: $/thirdparty /bin /log4net $/product /main /thirdparty /lognet <-- $/thirdparty/bin/log4net /working1 <-- $/product/main /thirdparty /log4net <-- $/product/main/lognet <-- $/thirdparty/bin/log4net part of work requires rebuilding log4net against .net 4 client profile , bringing in new version. normally, when upgrade third party component, it's checked $/thirdparty in appropriate folder, individual projects free merge latest binary, or not, see fit. as far have can determine, in order latest changeset $/thirdparty/bin/log4net need merge $/product/main , ...

on, e.g., link: http://4ad.com/releases/20949 , if @ album cover image in top right part of page, black border not quite square: there few pixels of height @ bottom. as far can tell image 300x300 pixels in size. there no obvious (to us!) sources of 4.5 pixels of height. know creating such discrepancy? since image inline , it's treated text, means few pixels added bottom leading. displaying image block (i.e. adding display: block; ) solves problem nicely.

i'm building java application gets data oracle database , puts jtable . my problem not able populate table, don't understand how it. javadoc useless. i don't understand why table doesn't rows: if ((report.getmsg()=="selecteventoall") && (report.getesito()==1)) { defaulttablemodel dtm = new defaulttablemodel(); eventi_tb.setmodel(dtm); try { resultset res_eventi = report.getres(); = 0; object[][] datieventi = new object[report.getrowcount()][5]; while(res_eventi.next()) { j = 0; while (j < 5) { datieventi[i][j] = res_eventi.getobject(j+2); j++; } dtm.addrow(datieventi[i]); i++; } } you can using custom implementation of abstracttablemodel. after results back, put them in list , let backi...

i'm new concepts of oo programming - programming in general still student. i'm working intern in department has me coding new structure base applications come. believe have idea behind oo down create "basic building blocks" , expand, expand , expand, until arrive @ complex object (for time being). i need put these "advanced" objects 1 how many many? can have 100 objects inside of bigger object if requires these "parts". i hope question makes sense everyone. i'm sure answer not going definite answer either need rule of thumb go by. i'd hate have 100 objects inside of 1 big 1 if there better design/programming technique. thank you. edit 1: thank responses i'm still little unclear. marked answer felt can continue have but... let me continue human example. human composed of many parts (or objects) , each part made of parts, way down single cell. human --> arm --> hand --> fingers --> thumb --> bones --> bo...

let's have string so: abcdefghijklmnopqrstuvwxyz1234567890!@#$%^&*()-_+={}[]\:;"'?/>.<,`~|€ this basicly list of characters on keyboard. how possible combinations for, let's say, "word" made of 8 of these chars? know there going millions of possibilities. cheers! difference between permutations , combinations you either looking permutation or combination. 'abc' , 'bac' different permutations, same combination {a,b,c} . permutations of 'abc': '' , 'a' , 'b' , 'c' , 'ab' , 'ba' , 'ac' , 'ca' , 'bc' , 'cb' , 'abc' , 'acb' , 'bac' , 'bca' , 'cab' , 'cba' combinations of 'abc': {} , {'a'} , {'b'} , {'c'} , {'a','b'} , {'b','c'} , {'a','c'} , {'a','b','c'} in python use...

say have customer table has record custid lastname 1 hamlin in 1 request customer last name hamlin custid=1. update last name kathy not commit it. another request comes try last name custid=1. kathy or hamlin. my understanding if both request different connection object(which should case) second request see hamlin. if same connection object , second request object see last name kathy. p lease let me know if above understanding correct? since you're in read-committed transaction isolation level (or higher, oracle supports no lower), not see changes made uncommitted other transactions, ever. beware in serializable mode, query may required wait other transaction commit or rollback, or alternatively transaction may rolled you. oracle supports read committed , serializable (you can pick, e.g., via set transaction isolation level ); other database systems additional support read-uncommitted, allow see updated not yet committed value.
