Hey there list-
I want to thank everyone here for all the help that you have
thrown my way. This list and the ruby-talk list are my favorite
online communities. Everyone is very nice and helpful.
I want to announce the launch of my largest rails project to
date. This site is a complete redesign and rebuild of the Yakima
Herald-Republic Newspaper''s website. In this project I have used a
local postgres db, a proprietary Baseview db(many newspapers use this
for their newsrooms) custom xml feeds from the AP newswire and an old
proprietary db at the Seattle Times. The project weighs in at 2237
LOC and runs on OSX on a brand new Xserve with lighttpd/fcgi.
Without further ado... heres a link.. <http://yakimaherald.com>.
Thanks again to the whole community for all the help. I would not
have been able to pull this site off without this community.
I think the scale of this project is a great testament to ruby
and rails as well. I was able to code all the ruby and rails in this
entire site by myself in 3 months while still completing 3 other
sites in the same time frame.

PS. Yes I know the layout uses tables and does not validate. I was
responsible for all the back end and the all the functionality. The
designer is a bit old school and not familiar with CSS
positioning ;-) But hows that saying go? Make it work, then make it
right, then make it fast? Well it works and is fairly well
performant. We will be redoing the layout in CSS in the next few months.
Nice work! I noticed a lot of javascript warnings in Firefox. Are you using AJAX. -L On 8/31/05, Ezra Zygmuntowicz <ezra-gdxLOakOTQ9oetBuM9ipNAC/G2K4zDHf@public.gmane.org> wrote:> > Hey there list- > I want to thank everyone here for all the help that you have > thrown my way.

Oops: "The document contains no data".....
Thanks Larry-
Yeah those javascript errors are from an outside vendor. We use
a javascript include from them to include our top jobs classified
listings and the javascript they gave us causes those warnings. I''m
not using any ajax at all here. I''ve spoken to the vendor and they
promise to have us new javascript code without errors next week.
Thanks-

I agree, I''d love to see some information like that if you wouldn''t mind. The site looks great, congratulations!

Here''s a decent write up for now. I am going on vacation today and will be back next week. When I get back I will put a full detailed write up on my blog. Just so people just reading this thread I am talking about this new rails site <http://yakimaherald.com> that I just launched. If anyone has any question they want to ask or want to look at any config files please feel free to contact me on or off list. I have good config files for lightttpd/fcgi and apache1.3 and apache2 fastcgi configs as well as ruby and rails setup on Linux and OSX. First off, if you want to see the site as it used to be for the last 3 or 4 years then you can see it at <http:// legacy.yakimaherald.com>. The old site was written in the worst spaghetti style php with no comments and most variable names like $x and $var. It was also very unstable and temperamental and consistently brought our network down at least once a month. I inherited the site when I took a job here a year ago. So it was in sore need of a rebuild. I started using RoR and ruby last November. I had been a php developer for 4 years before then. By mid-January I knew that I didn''t want to use php on any new projects. Since I am the sole developer here at the newspaper right now I was told "If ruby will make you happier and more productive then so be it. As long as you write decent documentation on whatever you build then use whatever makes you more productive." This was great and I started using ruby and rails for all new development. At the paper here we also do web design and application building for other local businesses. I built a few smaller apps with rails and built my confidence with the framework. So needless to say I unsubscribed from all the php lists I was on and have been reading ruby-talk and the rails list religiously for the last 6 months. -------Development--------- We got the approval and started rebuilding the yakimaherald.com site on May 1st 05. So it has been almost 4 months from start to finish building this app. When I say we I mean myself, the sole developer and my designer who made the views. But during those 4 months I still had to do the daily maintenence and upkeep of the papers website and advertising plus we built 2 or 3 smaller sites with RoR during these 4 months. So if I had worked on nothing else except the new site <http://yakimaherald.com> I estimeate it would have taken me about 2.5-3 months to develop with just myself and one designer. The final app in the state it is in today weighs in at 1479 LOC/models/controllers and 867 LOC/tests. I have 8 controllers, 12 models, 9 layouts and 69 view templates. The system is very heavy on content. There are 4 main data sources for the app: 1. A local postgres 7.x db for cms functionality and static page contents. This database holds the info that reporters and photographers input through the admin interface. And it also holds the new banner management system I wrote in ruby. Config is pretty much vanilla postgres and it performs great for my situation. I used the C postgres bindings. 2. A BaseView database that is a proprietary db that many of the worlds newspapers run for their newsroom database that holds all the content that gets printed in the paper. This db is not SQL. It has a proprietary scripting/templating language called LiveIQ. My rails model that handles this db is a custom ruby lib that I wrote. It creates a little DSL for querying the BasviewDB. I converts my ruby DSL into the LiveIQ scripting language on the fly so I can think in ruby. All the local Yakima and central washington content comes form this DB. This model accounts for 307 LOC out of my total app because of its complexity. I may be able to make this component open source because it could definitely benefit any other newspapers that use Baseview that are thinking about ruby and rails. 3. Custom xml feeds from the AP news wire. This content comes from the AP newswire subscription our paper has for the print version. It contains thousands of news items from around the world that get constantly updated throughout the day. These feeds are a little rough and require a fair bit of text processing before they are ready to go live on the web. The feed come across the wire as a Base64 encoded xml file. After unpacking it I have to scan for the relevant feeds we use out of the 2 or more thousand that are available. So my app processes and regenerates the online content every 1.5 hours unless we manually make it sooner. 4. The Seattle Times own the Yakima Herald. So we get some of our content from them.We don''t have a whole lot of content form this source yet but we will be using more soon as we just got the go- ahead to use their RSS feeds. So this app is very data and content heavy. When the index page gets regenerated after a cache flush it is pulling local postgres data, Baseview DB data from a server on the local LAN, Custom xml feeds from the AP wire and a few headlines feeds from the Seattle Times. This still is relatively fast. It takes about 500 milliseconds which is very good for everything it is doing to create the page including the network latency. But this only happens every 1.5 hours on one hit, the rest of the time it is cached .html files in the public/ dir these get served _fast_ by lighty. But it can serve up to 200 requests/sec with only 5 fcgi''s on no network latency dynamic pages. So for me Rails __CAN__ scale for largish web apps with a largish amount of users. -------Deployment----------- The new app runs on a brand new dual 2.5Ghz G5 Xserve running Tiger server with 1 gig of ram and 480Gb scsi RAID. We just got this in 10 days ago and I configured it myself. I am running Lighttpd 1.3.16/fcgi and it is running great. I initially tried to run on apache2/fcgi but in testing I got too many random 500 internal server errors. Lighttpd has proven itself to me over the last few months in production on some smaller sites and I think it is pretty much ready for prime time. We are getting around 40,000+ hits a day and thanks to judicious caches_page and fragment caching the server is barely breaking a sweat. Here is a paste of the relevant section of top running on the Xserve right now: PID COMMAND %CPU TIME #TH #PRTS #MREGS RPRVT RSHRD RSIZE VSIZE 26609 ruby 0.8% 12:46.00 2 16 132 22.9M 2.00M 24.2M 50.4M 26606 ruby 0.4% 12:11.00 2 16 129 22.9M 2.00M 24.2M 50.4M 26605 ruby 0.4% 14:43.20 2 16 137 23.0M 2.00M 24.1M 50.5M 26604 ruby 6.7% 17:06.96 2 16 133 23.2M+ 2.00M 24.5M + 50.6M+ 26603 ruby 12.8% 18:19.70 2 16 129 23.0M+ 2.00M 24.4M + 50.4M+ 26602 lighttpd 2.4% 4:58.44 1 10 39 4.25M 704K 4.59M 27.5M I have 5 dispatch.fcgi''s running (the ruby processes above) and they fluctuate from below 1% to around 16%cpu when they are working on a complex page rebuild after a cache is swept. But for the most part they just hover around 1-3%. And light is awesome it''s never gone above 9% cpu yet and it mainly stays around 3%! And these percentages go to 200% since there are dual procs. So for the most part I am using about 16% of all my processing power on this box for my rails app at any given time. I have a few launchd scripts(Tigers new xml version of cron) running for maintenence tasks. I have launchd launch an instance of the awesome ruby daemon daedalus at boot time. This daemon checks to make sure that lighttpd is running every 3 minutes and if it is not it relaunches a new instance of lighttpd/fcgi. It also wipes out the ruby_sess files in /tmp every 6 hours. I end up with around 8-9,000 of these session file in 6 hours and my app runs much better when these are not allowed to build up. Daedalus also bashes my cached pages every 1.5 hours. I have many data sources that wont work with cache_sweeper because they come from remote computers. So this script erases the pertinent files in public so the cache can rebuild with the new content from all remote locations. We also have an intranet page where people from the newsroom can go and run a script to clean the cache whenever they add new content they want to be picked up. I also have a lot of "glue" code written in ruby to do various text processing and ftp''ing and other things. The classified ads are processed to format them for online display. I have a bunch of admin tools written in ruby as well. --------Wrap Up----------- All in all I am _very_happy with my experience with Rails as well as ruby. Rails is a super productive environment for me to develop web apps in. But I have really fell in love with ruby _itself_. Ruby is so elegant and the syntax allows for me to open up code from 7-8 months ago and at an instance see exactly what it does. So it is much more maintainable than the PERL and shell scripts that I have replaced. I think that anyone considering rails and ruby for a decent size project should not be concerned with how does RoR scale. It scales great. The shared nothing architecture works great. If I need more power eventually I can just fire up another linux box and run fcgi''s on there. Rinse, repeat.. I am available for some consulting work if anyone wants any help in designing or implementing a ruby on rails infrastructure you can get in touch with the info in my signature. But also feel free to contact me at no charge if anyone interested in any of my config files or have deployment or other questions please feel free to ask. If anyone is interested in reading more and hasn''t fallen asleep yet this far into this rambling post, will have a more detailed article about the development of the http://yakimaherald.com website on my new blog next week( I will announce the address when its finished) Cheers... I hope I can help some people with any questions you might have as I have greatly benefitted from the very knowledgeable people of the ruby and rails community. -Ezra Zygmuntowicz WebMaster Yakima Herald-Republic Newspaper ezra-gdxLOakOTQ9oetBuM9ipNAC/G2K4zDHf@public.gmane.org 509-910-0773
