• is there something analogous to Connect.registerUsers in the Graph API

  - by timpone

  I am trying to figure this out. Basically, I'd like to reconcile my local emails with a users list of friends. I can see after OAuth token is established that I can get a list of users friends via http://graph.facebook.com/me/friends Would the solution be to keep track of a list of users friends over time and then reconcile with our local ids (in other words, i can know my id) and then use the friends API call to see if your friends are the same in local db?

• How fast are EC/2 nodes between each other?

  - by tesmar

  Hi, I am looking to setup Amazon EC/2 nodes on rails with Riak. I am looking to be able to sync the riak DBs and if the cluster gets a query, to be able to tell where the data lies and retrieve it quickly. In your opinion(s), is EC/2 fast enough between nodes to query a Riak DB, return the results, and get them back to the client in a timely manner? I am new to all of this, so please be kind :)

  When experimenting with (embedded) Apache Derby DB, I noticed that a fresh database, with no tables in it, takes about 1.7 MB of disk space. It's quite a bit more than my common wisdom would expect. Why is that? Are there significant differences in this between various database engines?

• Does it make sense to fragment cache static partials

  - by ash34

  Hi, I have my views and layouts split into multiple partials, some of them are static partials i.e, no data from the database being displayed here. Does it make sense to cache these to prevent the erb templating system from generating the html each time or it only makes sense to cache in situations where something needs to be retrieved from the db each time. thanks, ash

• How do I protect my website from javascript injection attacks when using rich text editors?

  - by VJ

  Hi all I am using the markitup editor to get the value for one of my fields and storing it a sql server 2008 db. Now I guess the problem is people having script tags and javascript in the editor and injecting malicious scripts and I have my validate input turned false. So can anyone suggest me a way to write a custom validation method that maybe checks for script tags and removes them...or just guide me through the steps i need to do ?...also are there other things also that I should be worried about..?

• Multiple dynamic method calls or declaring a variable in Grails

  - by user303979

  In my view, if I have a situation where I need to use a dynamic method (such as Domain.findByName("name")) in multiple places, would it be better to define a variable with and refer to that, rather than have the dynamic method in multiple places? I know this seems like an obvious answer, but I just wanted to make sure Grails doesn't cache it or something, and indeed two DB calls are being made.

• Encoding problem (Hebrew UTF8) in WordPress

  - by Tal Galili

  Hi all, I have a blog (of a friend) I am failing to fix: http://www.nivcalderon.com/ The language of the website is Hebrew, but the encoding scrambles the output, and I can't find how to fix it. I tried changing the DB colliation to be utf8_general_ci. I added this: define('DB_COLLATE', 'utf8_general_ci'); To the wp-config (and also this: define('DB_CHARSET', 'utf8'); But removed it later, since it didn't seem to fix the problem) Any ideas of what else to do ? Thanks
