Hey folks -

I'm new to the list, but I work for a Rails shop in Durham that writes custom apps as well as commercial products.  We've recently found ourselves with more work than we can complete on our own, and Nathaniel said that you wouldn't mind if I sent our job posting to the list.  So, here you are:

SciMed Solutions is a locally owned software company based in downtown Durham. Since 1997, we have been developing software solutions for the medical, scientific, and educational communities, and our business continues to grow in all of those areas. SciMed is an organization founded on entrepreneurship where new ideas are welcome.

Job Description
We are looking for an intelligent, ambitious individual to add to our software development team. Work activities will vary by project, but may include web application coding, database design, and product development. Employees should be able to take tasks/requests from start to finish without frequent supervision. Employees who are driven to improve their skills will be supported and encouraged to do so.

Job Qualifications
The ideal candidate will be a graduate from a 4-year college or university who feels that he or she can become a uniquely valuable team member. He or she will be a talented coder with the ability to learn quickly and work across multiple technologies and projects. Candidates should possess desire to work in a team environment and should embody friendliness, professionalism, patience, energy, and confidence. Candidates should also possess superior communication skills. A combination of intelligence, creative thought, ambition, and textbook knowledge will form the best candidate.

SciMed Solutions utilizes Ruby on Rails (RoR) as our web application framework. While experience with RoR is not required, technical experience should include some web interface coding using technologies such as HTML, XML, XSLT, JavaScript, AJAX, PHP, JSP, Python, Perl, or ASP. Talent in user interface design is also a plus. The best applicants will bring additional disciplines to the team beyond computer science and software engineering.

If you're interested in applying for this position, please contact me (Mason Matthews) at nfihr at yahoo.com.
 
Thanks for your time!
 
Mason F. Matthews
SciMed Solutions
327 West Main Street
Durham, NC 27701

We should really have a local jobs board to match up Ruby (and Rails)  
people with jobs and job seekers (full-time and contract/consulting  
types).

Is there an existing localized resource for this?

Ruby Rockstars is a worldwide job board that does a great job  
breaking the jobs out by type (contract, salary, hourly/freelance).

<http://www.rubyrockstars.com/>

It would be great to see something more locally-based, as long as  
there's supply to match the demand.

Perhaps Mason would care to come to our next meeting to announce the
position and meet us in person.  Sometimes job boards get stale or have
bogus postings.  Nothing beats a little face to face.

Message-ID: <F96F3A6F-3A22-478D-920D-D10990E79EF6@tonyspencer.com>

Has anyone ever constructed complex joins with ActiveRecord code  
successfully?  We've been unable to get AR to produce a query like  
the one below are are about to just manually parse the returned hash  
into the relevant models but I feel like its possible to do this  
without having to resort plain SQL execution:

     sql = "SELECT theaters.* , showtimes.*, movies.*
     FROM theaters
     LEFT JOIN  showtimes ON theaters.id = showtimes.theater_id
     LEFT JOIN  movies ON showtimes.movie_id = movies.id
     WHERE theaters.city_id = 420
     AND date(showtimes.date_showing) = date('2007-07-09')
     ORDER BY theaters.name, movies.title, showtimes.position"

     generic_result = Theater.connection.select_all(sql)

What SQL is generated when you try something like the following?

class Theater < ActiveRecord:Base
	has_many :showtimes
	has_many :movies, :through => :showtimes
end

class Showtime < ActiveRecord:Base
	belongs_to :movie
	belongs_to :theater
end

class Movie < ActiveRecord:Base

420, '2007-07-09'], :order => "theaters.name, movies.title,

It generates the following which looks perfect but the query it  
generates takes 78 seconds and my manual query only takes 0.24  
seconds.  I can't understand why.

Yeah its this extra JOIN its throwing in that is unnecessary and  
slowing it down so much:

     LEFT OUTER JOIN showtimes showtimes_theaters ON  
showtimes_theaters.theater_id = theaters.id

When that is removed and changed to showtimes.* the query is fast but  
I can't figure out how to tell AR not to add that JOIN.

Why not just use SQL? You know it'll always be faster than AR.

Or do both!  Specify associations in ActiveRecord using :finder_sql !

It looks like you have some redundancy in your data model.  Why do  
you need the showtimes_theaters table if each showtime has a theater_id?

There isn't a showtimes_theaters table.  That is the name (for a lack  
of a better description) of the unnecessary JOIN activerecord is  
creating.

JOIN showtimes showtimes_theaters ON...

Oh, I see -- it's doing the showtime.theater_id = theater.id thing  
twice.  I bet that's a side effect of this:

>>>>> 	has_many :movies, :through => :showtimes

(which you probably don't need anyway)

I think you still want to keep this association in your model.  However the
association table should be included automatically when you include the
:through relationship

Theater.find(:all, :include => :movies)

instead of

Theater.find(:all, :include => [:movies, :showtimes])

Message-ID: <F1B79275-E2EA-44ED-80C5-3EF1832CC373@geoffdavis.net>

I've got a new object in hand that I've created with build.  I save  
it.  Now I want to find the ID that was generated for the saved  
record.  Is there a good ActiveRecord idiom for doing so?

I could do a query to find the most recently updated object in the  
table, but that seems kind of lame and also prone to failure in rare  
cases when near-simultaneous inserts are going on.

If you're using build, you've created an object through the  
association proxy, right?

Something like this

@address = current_user.addresses.build(params[:address])
@address.save

You should be able to get the ID by asking for
@address.id

D'oh!  Please ignore that last email.  I just realized that the ID is  
in the object itself after saving and that my test was failing for a  
different reason.

I'm looking to make a small number (2-5) of tshirts, text only, possibly
front and back.  Does anyone have any suggestions of places that do this,
and about how much it might cost?

Thanks

Brian, I did this a couple times before by going to kinkos and printing onto
a t-shirt transfer.  Then i took the transfer to a t-shirt shop to have them
iron it on.  They did the ironing for free but I tipped them anyway.  Of
course they were images.  If its just text then the t-shirt shop could make
it bigger than 8.5x11 with better quality. I don't know any shops around
here though.  Let me know what you come up with.

http://nclogowear.com/ is near the Fairgrounds.

http://www.cafepress.com/ is who I use for an online source

I think you'll end up spending ~10 to 15 per shirt, but that's just a  
guess. It depends on how many colors, etc with NC Logo. And with  
CafePress, it's more like $15 to 20 a shirt no matter how many colors

Wow.  Cafepress is pretty slick.  Beats paying kinkos to use photoshop for
printing.

We discussed the Reject Conf videos at a previous meeting and I  
stumbled across the link tonight.

Reject Conf was (if memory serves) a "show up and speak" event for  
people who didn't get accepted to speak at Rails Conf. I didn't  
attend, but I've heard it was great.

http://groups.google.com/group/rejectconf/browse_frm/thread/

Enjoy!

No personal experience, but I've heard some bickering about the
quality of some of the cafe press stuff.  I'd love to hear otherwise
from anyone in the know.

I like everything I've gotten from them... it's just a little pricey.  
It's fine for small orders though.

As usual, anyone who's available is invited to join me at 5:30 tonight
at Baja Burrito (http://rubyurl.com/CGF) to grab dinner and some Ruby
chatter before heading over to Red Hat for the meeting.

While by no means required, a quick RSVP (just reply to this email
with "In!" or somesuch) would be great.

Looking forward to it,

Same here. I'm interested, but the link doesn't work, and I'm not going
to be able to make it to the meeting anyway. :-(

All right let's try this (sorry for the spam, everybody who doesn't care):

I have a fully configured and working MythTV DVR computer that I am no
longer using. It has the following specs:

* 220 Gb of HDD space spread across two LVM'd drives
* Athlon XP processor
* WinTV PVR-250 TV input and encoding card
* Chaintech CT-7NIF2 motherboard
* PS/2 keyboard and mouse
* All necessary cables except the power chord to the computer
* DVD drive

I spent a lot of time getting this set up and can verify that it is working.
However, I will not be available for technical support once I sell this. So
please, unless you know what you're doing, do not inquire into how to set it
up from me. All that you should have to do is update your Zap2It labs user
credentials (to download the TV schedule) and your cable listings (if you're
not in Cary) to get it running for you.

Yeppir,

I played with it a bit.  It looks pretty cool, but I'm a little leery
about putting it into production.

I'm still subscribed to the mailing list but there is very little
traffic so far.

One of the things I've got on my back-burner shelf is to try to
re-factor swiftiply_mongrel_rails to look more like
mongrel_cluster_ctl but I haven't found the cycles to even think about
it for some weeks.

Subject: [raleigh.rb] String substitution
Message-ID: <7365BE4D-E774-40C0-BB3D-EF7C841EC079@geoffdavis.net>

Is there any easy way to make string substitution happen short of  
calling eval?  (i.e. \s turns to a space, \n to a carriage return, etc)

I'm mucking around with the internals of Hpricot and think I have  
come across a bug in the way text nodes handle entity tags.  I work  
around the problem by calling inspect on the node and manually  
processing the entities, but then I have carriage returns mapped to  
\n, etc.  Calling eval on the result should be fine, but that makes  
me rather nervous.  I can do the substitution by hand with some  
regexes, but I worry that I'll screw something up.  Any suggestions?

One way is gsub with a block e.g.

irb(main):001:0> "abc\\ndef\\sghi".gsub(/\\[ns]/) {|m| m[1,1] == "n" ?
"\n" : "\s"}
=> "abc\ndef ghi"

Subject: [raleigh.rb] Interesting gotcha with exception handling
Message-ID: <C91C3415-C23A-454F-89DF-93D9EE2D96B1@geoffdavis.net>

I just hit an interesting gotcha that I thought I'd share:

In a Rails controller I have some code that sends email.   
Occasionally I get a bad email address that generates an exception  
during the send (e.g. the receiving SMTP server times out), so I  
wrapped the mail sending call in a begin/rescue block:

begin
	MyClass.deliver_my_email(address)
rescue => e
	logger.error(([e.to_s]+e.backtrace).join("\n))
	logger.error("Email address #{address} resulted in an error")
end

Much to my surprise, the exceptions continued to crop up.  After a  
little digging, I discovered that (unlike in, say, Python),

begin
	...
rescue => e
	...
end

does NOT catch all exceptions; rather, it only catches exceptions  
that inherit from StandardError.

A lot of methods in the Net module, including the mailer's send  
method, raise Timer::Error if things time out, and Timer::Error does  
NOT inherit from StandardError.

Here's the fix:

begin
	...
rescue Exception => e
	...
end

(or alternatively the following)

require 'timeout'

begin
	...
rescue Timer::Error, StandardError => e
	...
end

What magic is rails doing that makes this code work, which will fail in
standalone ruby?

class Klass
  def self.runnit
    puts "it works"
  end
end

proc(&:runnit).call Klass


Ruby standalone kicks out the message: wrong argument type Symbol (expected
Proc) (TypeError)

Thanks,

Message-ID: <4ce336a20707311935g329efdfel3874613d5567c675@mail.gmail.com>

Hello all,

First of all, I wanted to remind everyone that the Hoedown's a mere 10
days away, and if you haven't gotten around to registering yet, YOU
SHOULD DO THAT NOW!!! ;-)

Secondly, I need 6 volunteers for Friday, and another 6 for Saturday.
Volunteering basically amounts to showing up at least 30 minutes
early, helping out throughout the day (don't worry, we'll make sure
you get to see the sessions!) and planning on staying an extra half
hour or so afterwards to help us clean up. If you can help, drop me an
email back, and let me know if one of the days works better for you
than the other one.

Thanks all!
