question pretty straight forward, there way enable ttl on index level. means types created under index inherit enabled ttl. on documentation said "you can provide per index/type default _ttl value follows", wasn't able request ttl on index level. in case isn't possible, workaround can suggested ? in our environment new types created time, , data has removed after not needed anymore. you can accomplish using default option under mapping. under index , if put configuration under_default_ applied mappings these configurations not defined under same index. curl -xput "http://localhost:9200/test_index" -d'{ "mappings": { "_default_": { "_ttl": { "enabled": true } } } }'

i using java.util.prefs.preferences store application settings. here sample code- private static final preferences mpreferences = preferences.userroot().node("lab_exam"); public static void setdefaultpath(java.nio.file.path v) { mpreferences.put(default_path, v.tostring()); flush(); } public static void flush() { try { mpreferences.flush(); } catch (backingstoreexception ex) { logger.getlogger(appsettings.class.getname()).log(level.severe, null, ex); } } i flushing mpreference everytime put new value ensure data saved sucessfully. question is, preference automatically flush everytime put something, or doing correct thing? from javadoc of preferences : all of methods modify preferences data permitted operate asynchronously; may return immediately, , changes propagate persistent backing store implementation-dependent delay. flush method may used synchronously force updates backing store. normal terminatio

i have folder containing sequence of files names bear form filename-white.png . e.g. images arrow-down-white.png arrow-down-right-white.png ... bullets-white.png ... ... video-white.png i want strip out -white bit names filename.png . have played around, dry run -n , linux rename command. however, knowledge of regexes rather limited have been unable find right way this. obliged might able out this. if in directory above images, command is rename "s/-white.png/.png/" images/* if current directory images , run rename "s/-white.png/.png/" ./* instead. dry run, attach -n said: rename -n "s/-white.png/.png/" images/* or rename -n "s/-white.png/.png/" ./*

note: i'm using rendering engine render html pdf disables javascript default, i'm strictly looking answers using *.css . in report have table used accounting purposes 11 columns: 1st column counter (e.g. 1. , 2. , n. ) can range 3 digits. 2nd column 12 digit reference number. 3rd column address of reference number on previous column, can empty or @ least 50 characters long. 4th last column contains amount/currency/price data minimum value 0.00 , maximum can vary 8 digits comma separated number grouping. now let's table's width needs 1024px (varies depending on requirement provided *.pdf rendering engine). on point, want to: automatically make 1st, 2nd, 4th last column compute width based on content (that makes same reports have different column widths depending on longest column content on time of generation). the 3rd column adjust accordingly remaining width left original 1024px , add ellipsis end of line in case of overflow (important) .
