amazon web services - What is the cheapest way to send fast website update alerts to users as push notifications? -


i'm trying animal shelter deliver faster updates when new pet added website. happen between 0-20 times day.

the website simple data dump, animals in tables row delineation (easy parse) , have unique ids. when new pet added, ideally trigger mobile notification subscribed users (could email message). faster updates sent, better, checking every 30 mins or fine. because charity, want spend little possible on resources (because want able scale other shelters might want use this).

for instance mobile notifications, twitter seems candidate. looks needs wont run fees/restrictions.

the part i'm stuck on how best ping site updates , publish updates twitter. 2 options i've come are:

  1. build own system. use web crawler scrapy periodically crawl site , check new petids. using aws, think nano instance (~$57 year). using dynamodb cache existing petids seems small additional cost. use twitter api post updates

  2. use rss feed generator feedity. these seem pretty expensive: feedity $180/year hourly updates , $390 15 minute updates. has api integrated twitter.

i'd know if there better/simpler/cheaper/more obvious options may overlooking. thanks!

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
