i want store logs in db table (imported ef code). my code looks this: public pmcontext() : base("myentities") { configuration.proxycreationenabled = false; configuration.lazyloadingenabled = false; this.database.log = s => logstore(s); } private void logstore(string message) { tlog log = new tlog(); log.description = message; log.insertdate = datetime.now; logs.add(log); savechanges(); } public virtual dbset<tlog> logs { get; set; } i cannot use savechanges() (get error "sqlconnection not support parallel transactions") , if remove line nothing stored in db table. how can fix this? i think happens during savechanges call anywhere in app, because sql generated call logged, triggers nested savechanges call tries start own transaction. and there thing: savechanges call in logstore method trigger logging itself, you'd end starting infin...

i have ordered list of objects. can find item in list using following code: purchaseorders.firstordefault(x => x.ourref.equals(lastpurchaseorder, stringcomparison.ordinalignorecase)) what want select items in list appear after entry. how best achieve this? to index of item , select range? it sounds want skipwhile : var orders = purchaseorders.skipwhile(x => !x.ourref.equals(...)); once iterator has stopped skipping, doesn't evaluate predicate later entries. note that code include entry doesn't match predicate, i.e. 1 given reference. give entries order onwards. can use .skip(1) if want skip that: // skip exact match var orders = purchaseorders.skipwhile(x => !x.ourref.equals(...)).skip(1); this linear, mind you... if list ordered x.ourref find index binary search , take range there onwards... wouldn't unless find simpler code causes problems.

i have node server running on port 3000. i'll using handle apis, don't want urls in format example.com:3000/api/xyz i want in format: example.com/api/.. how route /api/ calls port 3000? example.com serving html pages, have nothing node. node used apis now. found varnish, looks overkill. an easy way put nginx in front of node server. you can setup nginx serve static media based on url patterns. can register non-static requests sent upstream node.js server on port 3000 node.js + nginx - now?

i wan't build class animal can find number of animals created. in scala there no option static variable, how can implement such functionality in scala (i looking non-specific solution)? thanks! for example in java: public class amimal { static int number_of_aminals = 0; public animal() { number_of_animals++; } } one option be: import animal class animal { animal.increment() } object animal { private[this] var _count = 0 def increment(): unit = { _count += 1 } def count: int = _count } though might want use atomicint.
