i'm developing web site, 1 of pages it's collection of divs. each div must printed 1 per page. i'm setting width/height of each div this: body .htmltemplate{ height:1140px; padding:0px; margin:auto; width:840px; } it seems work. before 1140px, had 1098px, divs jumped pages, changed 1140px the problem every once in while (let 1 of 6), printpreview shows half (or so) of width, , portion of height goes next page, have double pages print. in example, if have 40 divs, 80 pages. i've noticed when problem occurs, cpu usage in task manager jumps 100% do have idea of causing problem??? missing css attribute (i've tried page-break no luck)??? thanks in advance

i need loop through series of updates either involve adding / updating record, or removing it. updates need carried out in order, couldn't bulk delete @ end. is there efficient / quick way achieve through rails. currently i'm envisaging looping through updates. if it's delete request, deleting it. if it's not, searching it. if exists, updating. if doesn't, adding. i don't think, when dealing thousands of updates, going pleasant wondering if there more efficient way go process? you can try destroy_all delete_all update_all conditions/scopes like: user.where(:active => false).destroy_all
