i looking on section 7.3.1.1 in c++03 standard expecting find description of access rules items defined in unnamed namespace. the rules seem little different unnamed namespaces, since cannot qualify access items in one. know @ least within same translation unit, 1 can access items in unnamed namespace if not in namespace. example: namespace { int foo; } void something() { foo = 4; } if namespace had name, not this. so, rules defined in standard these exceptional rules apply unnamed namespaces? an anonymous namespace treated as: namespace unique_per_tu { // stuff } using namespace unique_per_tu; i'll try find reference here in minute. edit: it appears found in 7.3.1.1/1 an unnamed namespace definition behaves if replaced by namespace unique { /* empty body */ } using namespace unique; namespace unique { namespacebody } where occurrences of unique in translation unit replaced same identifier , identifier differs other identifiers

i'm jquery rookie , maybe i'm ask basic question, i'm struggling while figuring out why jquery chaining doesn't work in case. var container = $('#container'), items = container.find('ul.items'), moreitems = items.children('li.moreitems'); var config = { container : container, items : items, moreitems : moreitems } var app = myapp(config); function myapp(config) { this.container = config.container; this.items = config.items; this.moreitems = config.moreitems; this.current = 0; } myapp.prototype.myusefulfunction() { this.moreitems[this.current].fadein(); } let's suppose have div#container filled ul elements have more 1 li each. i'd access n-th li , fade element in, console throws me error, stating fadein has no such method. can please me sort out? jquery returns jquery object, a sort of array containing domelements . when do: this.moreitems[this.current] extract domelement jquery array --> have turn jquery object

i have these entities: public class post { public virtual int id { get; set; } public virtual icollection<tag> tags { get; set; } public virtual icollection<comment> comments { get; set; } } public class tag { public virtual int id { get; set; } public virtual icollection<post> posts { get; set; } } public class comment { public virtual int id { get; set; } public virtual post post { get; set; } } i want load post it's related tag s , related comment s's count linq . use this: var posts = session .query<post>() .orderby(t => t.id) .select(t => new { post = t, commentscount = t.comments.count(), tags = t.tags }).tolist(); do think enough? or have suggestion may better code? thanks. this highly depends on mapping , want fetched result. imho eager loading tags speed performance (select n+1) if want access tags list (assuming tags mapped lazy). var po

hopefully simple question - apologies if it's been answered nothing came in search. on s3 better organizes images smaller subdirectories, or keep them in 1 directory? in typical filesystem 1 namespace images in directories improve performance. flat structure thousands of images in 1 directory doesn't perform well. case on amazon s3? i can put user images users folder, post images posts folder, etc. or can put user images folders users/{userid} avoid having thousands of images in 1 users folder. this problem amazon s3 well, albeit significant storage requirements, see amazon s3 performance tips & tricks detailed answer including strategies partitioning object space. update (september 2013) – information in above link, while still largely accurate, has been supplanted newer document, s3 request rate , performance considerations .
