i trying retrieve default , active card of customer. (also keep in mind coding have, customer can have 1 card means if there way around it can help). some months ago used code segment working fine. seems stripe made updates , can't work now. current_user.stripe_card_id = customer.active_card.id the error is undefined method `active_card' #stripe::customer if need more information please let me know. edit: customer.default_card.id not work either. i used customer.methods check methods , found (default_source): current_user.stripe_card_id = customer.default_source works fine now. thank you

i'm not sure if question on-topic (and apologize if it's not), wonder how memory management can accomplished when creating operating system. understanding is: the os provides memory management. any programming language (above assembly, e.g. c) needs already managed memory (for stack frames , heap allocations). this sounds oxymoron. how can memory manager written if tool write needs memory manager in first place? must done in assembly? c not require managed memory. thinking of malloc library function, function (though standardised available user programs). an easy implemented memory allocation scheme following: char * free_space; void * kmalloc(size_t s) { char * block = free_space; free_space += s; return block; } // free not possible the pointer free_space must set during initialisation start of known free area of memory. might given boot loader through multiboot information. a more complex example can found in this code kernel wrote long...

i've written following pseudo-ruby illustrate i'm trying do. i've got computers, , want see if anything's connected them. if nothing connected them, try again 2 attempts, , if that's still case, shut down. this big deployment recursive timer running hundreds of nodes. want check, approach sound? generate tonnes of threads , eat lots of ram while blocking worker processes? (i expect running delayed_job ) check_status(0) def check_status(i) if instance.connected.true? return if instance.connected.false? , < 3 wait.5.minutes instance.check_status(i+1) else instance.shutdown return end end there not going large problem when maximum recursion depth here 3. should fine. recursing method not create threads, each call store more information call stack, , resources used storage run out. not after 3 calls though, quite safe. however, there no need recursion solve problem. following loop should well: def check_status return...

i've created custom treeview field - multiselect treeview. this field inherited sitecore.shell.applications.contenteditor.treelist overridden method add(): public class multiselecttreelist : treelist { protected new virtual void add() { bool alert = true; if (this.disabled) return; string viewstatestring = this.getviewstatestring("id"); var treeviewex = this.findcontrol(viewstatestring + "_all") treeviewex; assert.isnotnull(treeviewex, typeof (datatreeview)); var listbox = this.findcontrol(viewstatestring + "_selected") listbox; assert.isnotnull(listbox, typeof (listbox)); if (treeviewex == null) { sheerresponse.alert("treeviewex control not found..", new string[0]); } else { item[] selectionitems = treeviewex.getselecteditems(); if (sele...
