algorithm - Bucket sort---why's the input range important? -

i'm doing algorithms course @ uni, , read following sentence on introduction algorithms 3ed, p200: ...bucket sort fast because assumes input. whereas counting sort assumes input consists of integers in small range, bucket sort assumes input generated random process distributes elements uniformly , independently on interval [0,1) why input has in [0,1)? why can't uniformly distributed sequence sorted using bucket sort? i imagine interval [0, 1) used in order obtain theoretical result. notice, interval can converted given interval there no loss of generality. is, in practice uniformly distributed sequence can sorted using bucket sort.

Using RazorEngine for Text and Html emails -

i'm using razorengine v3.3 create emails using template files (emails sent using sendgrid web api). implemented base template can use own html helpers overriding writeto() method shown here . my problem emails part html , part text. html templates, use razor's default implementation html-encodes @model values. because of data comes user input. however, can't use same implementation text part html not interpreted when being read. so way see have 3 options: use @raw(model) in text based templates ignore html encoding create other base template text templates doesn't encode html modify html base template writeto() method doesn't encode anything the 1st solution seems safest, have 50 text based templates go through, , reduces readability. the 2nd solution seems cleanest me, prevent use of cache, doing razor.settemplateservice() reassign right base template ? what recommend doing ? thanks

java - Logging debug messages -

out of curiosity, there benefit when logging (using log4j) use above approach: if (logger.isdebugenabled()) { logger.debug("new session created"); } rather just: logger.debug("new session created"); is merely (potential) performance enhancement , still relevant? should used wrap debug output? thanks thoughts! in use case, no, there's no benefit whatsoever. however, if constructing new string, example, "new session create" + sessionid, you'd want avoid string construction , rather use boolean check. it's small difference, in large application, string construction, , associated garbage collection, become point of performance impact. if pass static strings, however, creating duplicate check, which, while small, has possible performance impact.
