performance - Meteor - android much slower than website -

-
hi i'm developing app on meteor has got browser version , mobile versions. in brief, browser version works well, transition between views/routes short, fast. when launch app on android (connected same db) there long breaks between routes. can 1s on few views higher 5 seconds. in database there 3 collections has got ~2k documents. not problem browser version, there problem on android. i tested kadira. can't see going on while routing example there enormous difference in login method. in browser takes maybe 15ms, on android 400ms. and weird (and important): in browser in end there observechanges on user collection. in android there observechanges on every collection , takes lot of time. of course try optimize current algorithm not problem because browser version runs well.

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.

if statement - Software Engineering: Conditionals evaluate "good" or "bad" order -

-
this question has answer here: best practice on if/else statement order 10 answers i remember reading in software engineering book once there typical rule follow when writing if else conditional statements order of evaluation. should valid case evaluated first followed invalid / erroneous case or vice versa? there proper order cases should evaluated first? example: if (good) { // exec block of code case. } else { // bad case. } or if (errorcase1) { // errorcase1 block. } else if (errorcase2) { // errorcase2 block. } else { // case. } no fixed rule such heard usage follow this if(usual) { (more often) } else (unusual) { (rarely occurring) } but if both have same function different properties better go unusual first usual can save 1 instruction. if(x == 0) // 1 {x = 1;} // 2 else {x = 2;} // 3
