Website Response Times An Article by Jakob Nielsen www.nngroup.com Users really care about speed in interaction design...A snappy user experience beats a glamorous one, for the simple reason that people engage more with a site when they can move freely and focus on the content instead of on their endless wait. 0.1 seconds gives the feeling of instantaneous response. This level of responsiveness is essential to support the feeling of direct manipulation. 1 second keeps the user's flow of thought seamless. 10 seconds keeps the user's attention. A 10-second delay will often make users leave a site immediately. uxperformanceinteraction
Prometheus A Poem by Lord Byron www.poetryfoundation.org The lightnings trembledThe sum of human wretchednessMaking Death a Victory Subjected to some great trialA hierarchical system of senseYou find reasons to keep living deathsufferingpain
The lightnings trembled And in thy Silence was his Sentence, And in his Soul a vain repentance, And evil dread so ill dissembled, That in his hand the lightnings trembled. idefiancesilence
The sum of human wretchedness Thy Godlike crime was to be kind, To render with thy precepts less The sum of human wretchedness, And strengthen Man with his own mind; But baffled as thou wert from high, Still in thy patient energy, In the endurance, and repulse Of thine impenetrable Spirit, Which Earth and Heaven could not convulse, A mighty lesson we inherit.
Making Death a Victory Like thee, Man is in part divine, A troubled stream from a pure source; And Man in portions can foresee His own funereal destiny; His wretchedness, and his resistance, And his sad unallied existence: To which his Spirit may oppose Itself—and equal to all woes, And a firm will, and a deep sense, Which even in torture can descry Its own concenter'd recompense, Triumphant where it dares defy, And making Death a Victory. deathdestinyhumanity
