we have ongoing discussion @ job best way deploy buttons on our websites. art directors ask buttons in pure css, prefer make spritesheets in photoshop. argument- kerning, text-effects drop-shadow , aliasing better coming out of photoshop. argument- lose seo points, translation engines can't change buttons. i'm sure there arguments both sides- missing obvious either of these arguments? well, one, pure css buttons load faster, few lines of code. many things can't done in css/js, have images, , consume bandwidth. can save bandwidth, should. alone killer argument if speed priority project. . about effects looking better out of photoshop... wouldn't neccessarily agree here. don't think browser implementations bad in way, have beat those, first. . also, drawing button image cost more time writing lines of code. same applies changing button. maintainability on css side ;) . i don't think translation argument applies. if "localization eng...

there must name when people try overuse design patterns. know terms anti-patterns , code-smell (among others), dont seem apply situation. dont me wrong, think patterns quite useful , powerful, many times see questions , code people seem try force use of pattern used pattern. more not simplicity absolute best way go. i did search , came this: when design patterns problem instead of solution? find interesting, dont agree with. if tag doesnt exist on stack overflow, @ least reserve right create please. not create new tag :) some ideas of called follow: over patternizing over patternized design pattern overdose i'd call overengineering -- doesn't need patterns, either. use kiss principle (as note).

i have created singleton class contains instance of memcachedclient (this object requires making connection server providing concrete example). initialize memcachedclient in static init block. if memcachedclient cannot create instance due connection error, means class worthless because has null memcachedclient instance. my question: best solution type of situation? how other people handling situation? the question (as stated in title) broad, depends of singleton for. in case, obvious question: if initialization fails, can expect issue solved in near future? cost of keep trying (redesign app not crashes downward in weird ways) instead of rebooting app? if not expect error solved easily, crash application (with proper logs/alerts/notifications). if want keep running until issue resolves, steps be: 1) pass initialization constructor of singleton (why put in static block if can control access constructor). 2a) while constructor fails, calls getinstance return null. ...

i use work microcontrollers. rtoss employ in applications not have free , malloc (and other calls assert), available, prefer have static in system. i have started employ linear algebra, of them need dynamic memory. matrices dense , 'small' (not more 10x10). i eigen (everything can static decided in compile time), apparently there bug calling asserts not provided rtos (even -dndebug). library should provide matrix decomposition routines (like qr, cholesky, lu...) i prefer c instead c++. suggestions? many in advance! anything wrong clapack? or straight fortran lapack (you can compile gfortran, part of gcc). [c]lapack's routines take memory buffers in arguments allocated, , not heap allocation whatsoever. routines take "work" buffers in addition other arguments (for example, dgesdd computing svd), can call them special "size only" argument, , in response required size work buffers, can allocate wish.
