ruby on rails 3 - Are there any performance/functionality differences between installing the New Relic RPM as a gem vs. as a Heroku add-on? -

-

i hosting rails 3 application on heroku , add new relic monitoring.

i notice heroku has add-on suppose sets you, notice doesn't create "real" new relic account - instead, creates heroku-specific new relic account can access through heroku.

what curious is: there differences in ...

  1. functionality

    mainly, heroku-specific add-on offer additional heroku-specific features other configuring service you? seems me that, if not, might better use gem avoid mysterious heroku monkey-patching?

  2. configurability

    does being able access new relic account via heroku have downsides (other annoying heroku header frame taking top of every screen)?

  3. performance

    does heroku set-up afford performance benefits on self-installation of gem?

  4. cost

    it looks heroku new relic add-on charges dyno. make more or less expensive overall comparable plan directly through new relic? if it's more expensive, have features justify cost other simplified configuration?

thanks all!

functionality

afaik not add functionality besides adjusting , viewing through heroku.

configurability

this biggest upside. heroku making things easier , plugin have install ready go.

performance

heroku plugins heroku-gems pulled in somewhere along line. need research how plugin made; if plugin used faster ruby faster new-relic gem made of ruby.

cost

i not think missing here. end paying 2 parties, whatever heroku charges cost being $0.06 dyno.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
