there few options in market store json data within mobile app (indexeddb, websql, etc.). i'm looking best solution (which not deprecated , supported commonly used browsers) store json data , use within mobile app created presentation / demo / portfolio purposes. my static json file structure looks follows: { "products": [ .. several records ], "users": [ ... several records ], "factdata": [ ... few thousand records ] } the question is, technology / method should use store above json data , not worry support ? local storage provides simple, synchronous key/value pair storage, performs poorly large amounts of data , possibly lock ui. websql depracated can still use it. can store around 5mb of data. indexeddb not supported on ios. i probabaly go websql now, other ways of storing data in json. maybe create database , api , make authorized rest calls it

i have following code delete objects in s3 "folder": deleteobjectsrequest req = new deleteobjectsrequest(); req.bucketname = "mybucket/my foder 1/my folder 2"; req.addkey("photo1.jpg", null); req.addkey("photo2.jpg", null); deleteobjectsresponse response = client.deleteobjects(req); response.httpstatuscode ok, , response.deletedobjects.count 2. however, actual objects still there. why? this bucket had versioning turned on suspended before created folder deleted. i worked out. should this: deleteobjectsrequest req = new deleteobjectsrequest(); req.bucketname = "mybucket"; req.addkey("my foder 1/my folder 2/photo1.jpg", null); req.addkey("my foder 1/my folder 2/photo2.jpg", null); req.addkey("my foder 1/my folder 2/", null); deleteobjectsresponse response = client.deleteobjects(req);

given regular expression, is possible find string matches expression programmatically? if so, please mention algorithm that, assuming string exists. bonus question: give performance/complexity of algorithm, if able. ps: note not asking this: programmatically derive regular expression string . more asking reserve problem. assume define regular expressions this: r := <literal string> (rr) -- concatenation (r*) -- kleene star (r|r) -- choice then can define recursive function s(r) finds matching string: s(<literal string>) = <literal string> s(rs) = s(r) + s(s) s(r*) = "" s(r|s) = s(r) for example: s(a*(b|c)) = s(a*) + s(b|c) = "" + s(b) = "" + "b" = "b" . if have more complex notion of regular expression, can rewrite in terms of basic primitives , apply above. example, r+ = rr* , [abc] = (a|b|c) . note if you've got parsed regular expression (so know syntax tree), ...

i have opened lot of files in sublime text. difficult read file names. showing few letters of each file name. attaching screen shot better understanding. how can see full name of each file? wanted fit full name of each file on screen. don't want hover on file see full name. you edit packages/theme - default/default.sublime-theme , change tab_min_width higher value (and save , restart st or resize window see change) or use different theme has wider minimum tab width. however, i'd highly recommend upgrading st3 - there new setting added in build 3048 called enable_tab_scrolling keep tabs wider, , enable see them all.
