i have web part property has personalizable attribute on it. there's button on web part changes property state. problem when there's user read permissions given him, property cannot updated, because sharepoint doesn't allow (btw, such users not allowed swith web part edit mode also). so question following: how determine whether user can modify personalizable property value (so can know when hide button)? know can iterate through permissions , read there, don't idea several reasons. sharepoint somehow knows if user allowed edit web part (switch edit mode) , wonder if there's property can tell if user allowed edit web part. thank you. the microsoft.sharepoint.webpartpages.webpart has permissions property that's type enum 3 values: allproperties, personalproperties, , none. try using that. if you're using .net webpart object can cast temporarily.

i in process of writing ruby script/app helps me compiling latex (at least) pdf. 1 feature want have should run pdflatex iteratively until pdf converges (as should, guess). the idea compare pdf generated in 1 iteration against 1 former iteration using fingerprints. in particular, use digest::md5.file(.) . the problem never converges.

so have list this alkaline_earth_values = [['beryllium', 4],['magnesium', 12],['calcium', 20],['strontium', 38],['barium', 56], ['radium', 88]] if use max(list) method, return answer strontium, correct if trying find max name, i'm trying return element integer highest. any appreciated. max(alkaline_earth_values, key=lambda x: x[1]) the reason works because key argument of max function specifies function called when max wants know value maximum element searched. max call function each element in sequence. , "lambda x: x[1]" creates small function takes in list , returns first (counting starts zero) element. so k = lambda x: x[1] is same saying def k(l): return l[1] but shorter , nice use in situations this.
