For Example -> I have requirement where I need to receive snmp traps from two different source and write those traps messages in two different log files? Please suggest what is the best way to do this?

8 year latter... This honors options hash:
def as_json(options={})
super({ only: [:email, :avatar] }.merge(options))
end

Quick tip, you need to have the `options = {}` param when you use this method, otherwise you get the following error:

`wrong number of arguments (given 1, expected 0)`

5 years later and still a valuable article. Thank you for posting, Jonathan.

Setting Cache-Control: no-store tells browsers to re-fetch the resource on *every* page view. This makes pages slow for end users. Using Cache-Control: no-cache makes sense for *dynamic* content (HTML, JSON), but it's better to use max-age=86400 for *static* content (images, scripts, etc.). Adding Stale-While-Revalidate makes pages even faster.

to_json
That's the reason I got lost my parameters when I tested my Restful API
After changing it to as_json, all problems are gone.
Really helpful. Thanks.

You saved me a ton of nerves with as_json :)

Re: How to get Developers and Designers to go to your Hackathon

"Winners: working prototype, signed up users, contracts signed. Not winners: slide decks, mock-ups, great ideas with zero execution."

This is an excellent point—winners should be selected as a proper reflection of the weekend's work and their use/misuse of the time to actually make something. Embedded in that critique is also a clue to why winners often get selected without prototypes or users. It's a reward for their presentation and perceived polish. I think it is a judging panel's job to weight things more appropriately like what you're suggesting. To not just award the presentation, but the current stage of executed product (and its evolution over the course of the event). After the recent Startup Weekend EDU I was thinking about how if it had been a 48 hour film competition, instead of screening a short film some of the winners had stood up at the end with a script for a feature and some cool concept art... but NOT a movie. That makes me sound a bit like a sore loser (since I was not on a winning team). I'm not that. I liked the winners' ideas and execution, but I saw a disconnect between an award for the weekend and an award for the scope of the idea and the presentation.

I can't agree more with you Shawn! It was my first hackathon too, but I wasn't able to fully experience it from the attendee point of view since I was one of the four organizers. I think back to the key tenants of that event: Meet People, Build Stuff, Have Fun. My expectations of every other event are driven by those. We had great people, excellent projects, and we all had a fantastic weekend.

Ah yes, Groundwork should be on the list. Are there any other events I've missed?

jjulian — Tue, 18 Dec 2012 13:01:01 -0000

That's a great point, Kate. Not every event can be inviting to youth (I'm thinking Startup Weekend), but the more exploratory and "fun" events should definitely make children welcome. The kids at ArtBytes seemed to have fun exploring the museum and 3D printing.

So many good points in this article. My favorite event that was ever held was the First Baltimore Hackathon. It was my introduction to the Baltimore Tech Community (despite having lived here all my life and being in the tech field professionally for 12 years by that point). It was exactly what I wanted to get out of an event as a developer: Low pressure, more about hanging out and working on cool things than building a business or winning a competition. It gave me a chance to set aside time to work on something that I thought was cool but I didn't feel any pressure if I totally bombed at it.

Sage counsel. I second Kate's recommendation about youth involvement. At Groundwork (another one for your list at the end http://gb.tc/events/groundwork ) Eliot Pearson's son and my daughter played a lot of Minecraft, but also soaked up the geeky atmosphere while creating artwork that went to award-winning teams.

Jonathan - The one piece that you missed and that I didn't think of until I saw Adam's name at the bottom is that events should make an effort to get youth involved. I'm pretty certain that he's more likely to come to an event where his children are welcomed and entertained than one were he feels like they'll clash with the environment or structure. - K

#as_json generates a hash. Excellent.
There is no equivalent #as_xml to generate an xml-intended hash, so presumably you use #as_json chained with #to_xml. Why isn't #as_json called #as_hash instead?
Coupling the default intended rails behavior with the actual behavior of the method itself in the name of the method is not a good idea, and it confuses me why Rails did this.

Oops, I had a typo in my MyController pseudo code.

It should be this:

class MyController < ApplicationControllerrespond_to :jsondef show@user = User.find(params[:id])
respond_with(@user , :include => {:addresses => {:include => :email}})
end

Which I want to refactor with something like this in the model:
def as_json(options={})super(:only => [:email, :avatar], :include =>[:addresses => {:include => :email}])end

But I get an
undefined method `macro' for nil:NilClass
