Bob Morales: Aug 18, 2006; ~~Just wear the fucking mask, Bob~~

I don't care how many people I probably infected with COVID-19 while refusing to wear a mask, my comfort is far more important than the health and safety of everyone around me!

I worked in a shop like that, where the pressure to deploy anything at all was interfering with my ability to make quality software.

I went to the management and said, "my last day is in two weeks," and haven't looked back. If they won't let you make quality software, they deserve what they get, and you don't deserve to get stuck with it.

I came here from being a sysadmin at a place where I had zero to do (and took a pay+benefits cut to come here). This is my first actual programming job even though I've been toying around with various languages etc for the last 15 years. I'm also in the mid-west where there aren't any tech jobs that don't suck, so I have to either build some experience here for a while and then move, or go back to sysadmining po-dunk networks.

They also hired me with 5 days RoR experience

I've been in a lot of dev shops that were at that level of errors, untested code and general horribleness, and while it's tempting to say "let's stop everything right now and do nothing but testing / refactoring", a lot of times that really just isn't realistic.

One approach that I've found works well is to set explicit rules about how you're going to deal with technical debt, in a way that you can get buy-in from the higher-ups that it won't grind development to a halt. Here's a good list of rules to start with:

Bugs are addressed the way they are right now, but developers need to first create a test that fails due to the bug. This makes regression testing easier (which I'm guessing based on what you've said is a huge problem for your QA department), and after a few months, the hotspots in your code will have decent coverage.
New code is developed using TDD.
Half a day every week is solely devoted to reducing technical debt. I'd personally handle this by allowing devs to work on whatever they want - they will probably have the best idea where the problem spots in the code are.

Even just 1 and 2 will go a long way to improving your codebase. You'll never have 100% coverage, but if the only areas in your code that aren't covered never change and never have issues, it's far less of a concern in my mind.

Could someone recommend a good Ruby on Rails RSS feed to follow?

I found when learning Python that subscribing to the Planet Python feed was great for getting to understand the community and the technologies out there. There is planetrubyonrails.com but I can't find a way to subscribe to it using Google Reader, and searching for 'ruby on rails rss feed' of course yields results about how to program one!

What's the 'main' page of my app called, or does it have a file name?

Basically what I want to do is allow Googlebot to index https://www.myapp.com as well as stuff like https://www.myapp.com/info or https://www.myapp.com/about

But nothing else. I can allow the other pages but if I disallow / in the robots.txt, it can't hit https://www.myapp.com. Which is expected.

It's also very common to have a static index.html in public/ for the front page if the front page doesn't change much. The front page is usually hit hard and it's blazingly fast to serve a static file than going through the whole Rails stack.

I use that just because I can use markdown embedded in haml to make my static pages:

http://guides.rubyonrails.org/routing.html#using-root

We have :welcome routed like that, but for some reason it doesn't work the way I want it to. They're just visiting / which goes through, and not /welcome

I'm just going to block all the ones we don't want in the robots.txt. Basically what happens is we get Exceptions from GoogleBot hitting random pages in our site that it shouldn't be. Or at least, we don't expect it to be.

customer-subdomain.ourapp.com/register/demo-password/ and stuff like that (which is actually done in AJAX)

# ? May 9, 2011 23:21

NotShadowStar: Sep 20, 2000

Are you saying that you want / to be redirected to the URL /welcome?

What root :welcome does is match / to WelcomeController#index, not redirect.
Also, if some of your application errors are coming from Google trawling through your site and hitting AJAX only URLs, your AJAX setup is probably incorrect. Essentially you want the inverse of what this document tells you to do.
Actually, it takes work to get Google to find AJAX URLs, like it took Twitter and Gawker a whole site restructure to have an AJAX front end that's also Google indexable. Something else is really screwed up with your site structure.

Unrelated to your problem, but I'd strongly advise against subdomains. They make full stack integration testing much harder than it has to be. And there's not much business value in subodmains. Most people don't know what browser they're using let alone care what the url looks like.

If you use this and are on heroku, you should look into setting the cache control headers to get varnish to cache it for you. It's not going to make a huge difference, really, but hey why not?

The value in subdomains really becomes a lot more apparent when you get into multi-tenancy problems. If you can segregate / scope your entire data layer based on which subdomain is being accessed, things get a lot easier to deal with.

Everything I've read agrees with you, but they're 100's of customers and ~ 20 products in.

I put the robots.txt in yesterday, and Googlebot is still hitting us.

code:

User-agent: *
Disallow: /welcome/
Disallow: /register/
Disallow: /store/
Disallow: /toolkit/
Disallow: /content/
Disallow: /home/

But the bot is crawling /welcome/pilot and /home/register still

I made a thing.

It plugs into a Rack application on Ruby 1.9.2 and allows you to browse the source.

For Rails 3:

Add gem 'cans' to your Gemfile.
Add mount Cans::Application.new, :at=>'/cans' to your config/routes.rb

Browse to /cans/browser for the pretty backbone.js-based browser.
Browse to /cans/ for the less pretty HTML-only views.

That sucks. In general, I like uploading directly to s3, that way you can not tie up one of your web processes with an upload. However if uploading is a rare thing, it probably doesn't matter. Also, be wary of relying on the local filesystem, it'll make it harder to scale to multiple machines.

I'm not using linux for my dev machine, but I can't recommend rvm hard enough, even if you find a distro that treats ruby well.

This, though I will point out that before RVM came around, I made do with finding a distro-compatible third-party Ruby build (e.g. a Yum repo or Ubuntu PPA) that was new enough (takes a short bit of searching / vetting), and installed Rubygems from source (easy as falling off a log). Worked pretty well.

It still has some flaws. It takes forever to start up for one. I'm not a big fan of how you have to do "redcar install" after every upgrade. It's still my editor of choice though. It's just so easy to jump around to different files with CTRL+T. That, the syntax highlighting and auto-indent are its strong points IMO.

I reinstalled my Ubuntu machine and am trying to install Rails3 (following this guide http://www.christopherirish.com/2010/08/25/how-to-install-rvm-on-ubuntu-10-04/ )via RVM but editing my .bashrc file isnt working. I think that last line

code:

if [[ -s $HOME/.rvm/scripts/rvm ]] ; then source $HOME/.rvm/scripts/rvm ; fi

fi

and after looking around my home directory I see that there is no .rvm folder which would explain why rvm notes doesnt work.

Theres a /rvm/scripts/rvm in /usr/local but copying that folder to my home directory doesnt do anything :/

That probably means you ran the install as root, which gave you a system-level RVM installation instead of a user-level one. That's not a problem as long as you follow the instructions accordingly: https://rvm.beginrescueend.com/rvm/install/

I'm just learning Rails (and ruby and web development) and I heard about these fancy-pants things called models, views and controllers, and I feel like I should use them properly.

I have this

code:

  <b>Total support:</b>
  <%= debate.supports.count - debate.contests.count %>

in my view and I want to move the subtraction into its own function (since it will soon be doing more then just subtracting some stuff)

Where do I put it? I tried the DebatesController class and the Debate class but got erros when I do it any way besides this way.

I think the model is the best place for this.

Assuming 'supports' and 'contests' are separate columns in your debates table, add this to Debate class (model):

code:

def total_support
  self.supports.count - self.contests.count
end

then you can just call debate.total_support (or whatever you decide to call it) from your view.
