unix - bc within perl fails to get going -


i trying run bc unix command within perl seems hard right now. using bc because numbers using beyond 64bit in size. here's code snippet.

$temp_addr = "a5a5a5a5a5a5a5a5"; $temp_data = "82100000"; $bc_addr = `echo \"ibase=16;obase=16;($temp_addr/8)\" | bc`; $bc_data = `echo \"ibase=16;obase=16;($temp_data*200)\" | bc`; die "$bc_data, $bc_addr";

the output code when run like...

02 08 20 08 03 09 14 ,  02 00 14 05 04 06 12 13 04 04 15 18 07 11 15 02 00

now expecting o/p in hex , valid 1 @ that. 1 flies on head. when run bc in shell directly things fine.

set obase=16 before ibase=16 , work charm. otherwise setting obase 0x16, not want.

iOS: Performance of reloading UIImage(name:...) -

i have tableview , each row has icon. 90% of rows have same icon. in cellforrowatindexpath method load image assets folder this: var cellimage = uiimage(named: "myimage") does pose performance problem? os somehow smart enough it's same image each time? better if loaded image once , saved in class variable , assigned each time? uiimage 's named: api does kind of caching. if @ uiimage's documentation , states: use init(named:in:compatiblewith:) method (or init(named:) method) create image image asset or image file located in app’s main bundle (or other known bundle). because these methods cache image data automatically, recommended images use frequently.

How to prevent logback from emitting repeated "Empty watch file list. Disabling" messages -

i have logback configured logback.xml located here: http://pastebin.com/kuquekxy . every minute, see log message emitted of form: 18:26:21,486 |-info in reconfigureonchangetask(born:1478715201485) - empty watch file list. disabling why happening , how can rid of these? i can tell why happening, not how rid of them. the reconfigureonchangetask log line when doesn't have files watch. and doesn't have files watch because file in jar, , only watch files on filesystem . makes sense, because files within jar file don't change.
