Jazzers and Programmers (Nick Sieger)

Nick Sieger had two talks ready and put it to an audience vote. They could pick either:

• Pointless and Time — Wasting Things You Can Do with JRuby, or
• Jazzers and Programmers

As you can see by the title, the audience picked “Jazzers and Programmers”.

Experience the music! Carsten Nielsen put together a muxtape page where you can hear the samples of jazz that Nick used in his presentation.

You should also see Nick Sieger’s blog entry Jazzers and Programmers, which is his presentation in article form.

- Let's trace the evolution of Jazz
    1. Swing
        - A popular, easily accessible style
    2. Bebop
        - Miles Davis
        - A little less accessible
    3. Hard Bop
        - Addition of soulful, gospel r&b elements
    4. Free Jazz
        - Improvisation with minimal themes
        - Visceral emotional style
    5. Jazz rock / Fusion
        - Miles Davis (again!)
        - On the Corner
    6. Today
        - Postmodern jazz?
        - Jazz rendition of "Iron Man"

- Programming is on a similar path
    - C: like New Orleans hot jazz
    - Java: like swing? (Groans from audience)
        - Both are very accessible to the masses, mainstream
    - What's in the future?

- The basis of jazz is the rhythm section
- The bassist is typically in the center of the rhythm section
    - Responsible for both the harmonic foundation *and* beat
    - Often established using a walking bassline
- Piano and drums: comping (short for "acCOMPanyING")
    - In jazz, these instruments are more about creating sonic textures
- The rhythm section is analogous to a programming library, framework or pattern
- Bass/drums/piano == Model/view/controller

- Musical structures
    - In a jazz piece, it's typically head / solos / head
    - The theme is established in the head at the beginning
    - The solos are based on the theme, but each musician is free to improvise
      based on the theme
    - The closing head ties everything together
- The Real Book
    - A big book of sheet music of jazz standards notated by working musicians
      (without bothering to get the rights)
    - Allows musicians who don't normally play together to have a common
      point of reference
    - In a jam session, musicians call tunes out of the Real Book
    - It's essentially a "patterns book"
- This like common structures provides a common language and organic conventions
- There is no "W3C Committee"-like body that dictates how you play jazz
- It's all conventions established by musicans floating between bands

- Improvisation separates jazz from other styles
    - Ornette Coleman quote: "When I found out that I could make mistakes,
      I knew I was onto something."
    - The structures in jazz provide a framework that actually makes
      improvisation possible
    - Inronically, it's these constraints that free you

- Communication and persuasion
    - Improvisation is all about being convincing
    - It has a back-and-forth conversational element
    - It's a non-verbal kind of communication
    - Consider the act of "trading fours": that's where different musicians in
      a jazz combo take turns playing for four measures, "trading" back and
      forth with each other: perhaps sax 1 takes 4 measures, then sax 2, then
      the piano, then the drummer.

- Do programmers improvise?
    - The best programmers have a sense of spontaneity
    - Consider continual rewrites
        - Fred Brooks says "Plan to throw one away"
        - I say "Why stop at one?"
    - I like it when developers do live coding in front of an audience rather
      than doing it in advance and running it, or just showing a screencast
      of them coding
        - It's fascinating to see the process, especially when it's a good
          programmer doing live coding.
        - Jazz musicians make "mistakes" all the time, but they're not mistakes,
          they're the music
        - "Do not fear mistakes. There are none." -- Miles Davis

- Coding jam session
    - Musicians jam together; coders should too!
    - When commenting on a fellow jammer's code, think in terms of
      "Yes, and..." rather than "Yes, but"

- Jazz musicians and altered states
    - "Write the test cases when sober. Write the code when you're drunk."

Do the Hustle (Obie Fernandez)

From the RubyFringe program booklet:

Sales is an a rt that very few technical people have mastered. Very few. It takes patience, confidence, empathy and a whole slew of other skills mixed together — a brew that is seriously difficult for many geeks to figure out. In this talk, Obie will leverage his experience successfully selling consulting services for both Thoughtworks and Hashrocket to help you with the following questions: How do I figure out how to price my services? How do I figure out the kind of work I want to sell? How do I write contracts and statements of work? What about proposals? And RFPs? How do I close the deal?

---

- My formula: Get into programming, write a bestselling book,
  start consultancy, profit!
- I've had to make my own luck
    - I come from a humble background, with no prospects coming out of
      high school
- I landed my first job in IT in 1996
    - It was as a Java programmer
    - I read "Teach Yourself Java in 21 Days" and wore a nice suit to interview
    - I knew how to present myself
    - That's what I'm talking about today
- I'm talking about hustling!
    - This is not about scams or cons
    - It's about being able to jump on opportunities when they present themselves
    - The dictionary definition of "hustle" is to "obtain by forceful action
      or persuasion"
    - Yes, I do mean "forcefully"

- The sales cycle, which I will discuss, is made up of these phases:
    1. Marketing
    2. Qualifying
    3. Closing* -- ALWAYS BE CLOSING
    4. Maintenance

    - Marketing
        - Take a holistic approach
        - Looking good is a must: often it's what makes or breaks you
          when trying to get other people to "buy into you"
        - Your site/blog is your face -- make sure it looks good!
        - HashRocket logo:
            - Based on the "=>" is hashes
            - $15K for design work
            - Worth it, because it's gorgeous
            - Don't cheap out on your visual identity!

        - Have business cards
        - Having a business card determines whether or not you have a
          sales conversation -- if you've got a card, it's much easier to
          start one that has a hope of converting
        - Your website is like a business card: it should have correct
          and complete contact info
        - Having a phone is very important, and having the phone number on
          your site is also very important!
        - We got a lot of customer call within a day of posting
          our phone number on the site -- we tripled incoming sales contacts!

        - Encourage word of mouth
            - Read "Never Eat Alone|
            - Be altruistic and help people, do favours
            - "Seed the interactions that lead to good word-of-mouth"

    - Qualifying
        - Narrow down your offerings by defining products -- don't
          "just develop software" in a vague sense
        - Give yourself constraints
        - One great constraint to have is a minimum billable rate
        - Leads should not be qualified by the ultimate decision maker

        - Defining success
            - You can't rush the sales process
            - Ask yourself this question: Is the team prepared to fulfill
              or exceed the project requirements? If not, don't take it on!
            - Determining success criteria involves getting to know the
              prospective client via conversations. These can be face-to-face,
              or online, but you must get to know them!
            - Your own success criteria should remain constant
              -- write them down!

    - Closing
        - Use master service agreements with attached
          statement of work documents
        - These are easy to get client to sign up for, since they
          have no monetary component
        - Once someone signs this, they're the client!
        - Separate deliverables into "type A" and "type B"

        - Learn to negotiate!
        - You're worth more than you think
            - Average rate of $150/hr
            - See "Predictably Irrational" by Dan Ariely

    - Client management
        - Do remarkable work
        - Read "Purple Cow" by Seth Godin
        - Don't fear your clients -- make them fear you!
            - Not in a bad, trembling way
            - Make them afraid they can lose you if they misbehave
            - Client yelling at you: grounds for firing the client
                - Yes, you can fire a client!

Being Dumb and Using it to Your Advantage (Matt Todd)

From the RubyFringe program booklet:

You’re in over your head, dumber than you (and others) think, and you want to matter to your community. What do you do?

There are many good developers in this same position sitting on some dumb ideas simply because they are dumb. I’m challenging you to implement them…let me tell you why. First hand experiences from some dumb developer.

---

- I'm a nobody
- Contributed very little

- Lacking good judgement is not a bad thing all the time
- Be open to doing things that may seem a little ridiculous
- We are too smart for own good
- Tons of ideas bad in long run good in short run
    - Canvas for PHP
    - Building from scratch: a stretching experience

- From doing dumb things: taking chances, making mistakes and taking chances, you get:
    - Code
    - Confidence
    - Experience
- "Don't let your good judgement get in the way"

- What I learned from Halcyon
    - Anything can happen
    - A lot of tech things, maintaining a project openly, you don't combine an app,
      server and framework all together
    - I "don't want to fail to connect"

- Challenge!
    - Ideas sitting around the back of your head -- take 'em out! Work on 'em!

- Advice
    - Set yourself up for good problems (such as too many people using your app)
    - Set goals (including "make it work")
        - These goals don't have to be time-based

- "Creepy eyes! The end!"

The Framework Mass Index: Why Your Web Framework Sucks and You Should Build Your Own (Jeremy McAnally)

From the RubyFringe program booklet:

Frameworks are getting fat. Many times it’s just as easy to build your own stuff that does what you want rather than shoehorning what you want into an existing framework. This talk will discuss experiences in shoving specific functionality into a general framework and some options for curing the problems that were encountered.

---

- Pete Forde: "It's pronounced Mack-uh-NAL-lee."

- They told me to come here and drop a brain bomb
- I'm going to present what is "just a bunch of old ideas that need to be repeated"

- Beased on Obie's earlier talk, I checked our site and realized that our contact
  page is broken. That's probably why he haven't gotten any new work in a while.
- I'm starting a new project -- a magazine called "The Rubyist", which needs writers,
  editors and so on. If you're interested in contributing, we want you!

- Main point: Keep your framework within its domain
- I like Rails
- I like like Merb (except for 413 gems)
- But frameworks are getting fat
- "We're suffering from framework envy"
- There are 13,000 classes in .NET
- There are 13 web frameworks for Ruby
    - Rails has 521 classes
    - Merb has 400
- BMI: Body Mass Index
    - A measure of obseity based on a weight-height ratio
    - Not necessarily the best measure: Tom Cruise is obese, if you go by BMI
    - Maybe the equivalent for BMI in frameworks is WTFs/poung
    - Comparing the WTFs/pound in frameworks:
        - Merb has 16,000 WTFs/pound
        - Sinatra has 7 WTFs/pound
        - Rails has 12 quatrillion Heinemeiers
        - And Camping just has "true"

- Domain Specificity
    - Cruft is getting in the way
    - Have we forgotten YAGNI?
    - LOL AGILE
    - wxWidgets is a framework that's good at GUI
    - .NET is a framework that's good at...?
    - Rails is a framework that's good at database backed, front end driven
      web apps
    - Rails is not good at federated web apps
    - Integrating legacy systems with Rails is a pain

- Don't molest a framework
    - Problem: Ruby is a hacker's language, and hackers love to hack
    - You can open up a class and mess with it
    - This is okay, unless it's bad:

    - 3 things to consider when making your own framework for a specific
      domain
        1. Joy vs pain ratio when it fails
            - Does it take too much code to make things happen?

        2. Wrench meet mail
            - Are you using the right tool for the problem?

        3. Conventions rock
            - Favour conventions, be consistent!

    - Tools at your disposal:
        - Rack -- framework for writing frameworks
        - merb_core (if you need a little more fanciness)

- Use common sense: Don't hack a framework for the sake of hacking!

There Will be Porn (Zed Shaw)

From the RubyFringe program booklet:

I’ll go through 10 truly horrible ideas that I’ve implemented or thought about, all created just for RubyFringe.

---

- Pete: Don't be put off by that "AUGGGGGH!" stuff on his blog...
  he's really a super-nice guy

- GWAR-riffic intro song (available at his site)

- This is the best conference!
- Small conferences are the best; the giant conferences suck

- This is my Ruby retirement
- I will not be back. No more Ruby code. No more Ruby conferences
- WorkingWithRails.com -- if you're worried about your popularity on this site,
  you're a whore
- I'm currently writing a book, "How to build the greatest ruby server ever"
- I'll also be writing a book after that: "Protocols and performance"
- I consider myself an observer and an "anti-pundit"
- And now, my ideas!

- Idea #1
    - To-do lists are hot
    - Porn is even hotter
    - Social networks are hottest!
    - I combined them
    - Imagine a giant todo list. Just one, where everybody just adds to it.
      And at the same time, you upload porn!
    - You get everyone's to-do lists and everyone's porn

- Idea #2
    - Pornmagnet.tv
    - Imagine Miro but with all the free porn uploaded and ready for you!
    - One-handed operation
    - If you can't be a chick magnet, be a porn magnet

- Idea #3, which I actaully might just implement
    - chaos2congress.us
    - It hate politicians of all stripes. I want to get rid of all of them
    - Maybe I'll start by just removing incumbents. I want to fuzz incumbents.
      Let's pick a random guy and make his day bad
    - The website would list all memebrs of congress members
    - People could leave short statements about any member of congress
      that would "kick 'em in the nuts"
    - The top-rated and verified statments would be collected
    - Based on those, the site would automatically launch a war-dial campaign to
      "fuck up that senator's day"
    - "Oh wow, I'm so not getting back into the US"

- I'm so tired of making web applications
- I put together some code to help me play some "fucked up songs"
- The result: Inculcator
- Just PyGame and Ecasound
- Didn't take long to make

- I've got T-shirts!

Zed devoted the rest of the presentation to his Ruby “swan songs” — four numbers which he constructed on stage using Inculcator to record tracks and the salmagundi of music and computer gear shown in the photo below:

Zed’s gear consisted of:

• Traveler guitar
• Boss “Dr. Beat” DB-90 metronome/guitar preamp
• “Snowball” microphone by Blue Microphones
• and a subnotebook laptop that I can’t identify.

The four numbers he constructed and performed were:

1. Zed Jumped the Shark (940K MP3)
2. Matz Can’t Patch (1.7MB MP3)
3. Don’t Fuck Up Chad’s Community (2.1MB MP3)
4. Goodbye Friends (3.6MB MP3)

You can download them by clicking on the links above or by visiting their Internet Archive page, where you’ll find them in various formats. Zed put them in the public domain — in his own words: “I’ll nevermanke any money off them.”

In the photo of Zed’s setup, you can see four boxes on the left side. They’re t-shirts which have been compressed into cubes. Zed customized them by hand-painting “ZSFA” (short for “Zed’s So Fucking Awesome”, the name of his blog) on them. They were rewards given to people who supplied the vocal samples (“Zed jumped the shark”) for Zed Jumped the Shark. Those people were: Hampton Catlin, Deb, one unidentified person and Yours Truly.

Here’s what the t-shirt looked like after I extracted it from its cube:

For Zed’s perspective on the event and his presentation, see his article titled RubyFringe 2008 – Killing Floor in Toronto.

Here’s the first of my notes from RubyFringe, the non-corporate, almost-non-sponsored, edgy Ruby-but-not-Rails conference organized by the folks at Unspace and held in Toronto (a.k.a. “Accordion City”) on July 18th – 20th, 2008. I’ve read on a lot of blogs that people have been calling it “the best Ruby conference ever” — I might go so far to say that it’s the best tech conference I’ve been to.

This first set of notes covers the following presentations:

• Adhearsion (Jay Phillips)
• Deployment Monoculture / Scaling Ruby Down (Dan Grigsby)
• Rockstar Memcaching (Tobias Lutke)
• Living on the Edge (Yehuda Katz)
• Testing is Overrated (Luke Francl)

Adhearsion (Jay Phillips)

From the RubyFringe program booklet:

Jay Phillips will talk about what’s been changing in the Adhearsion and VoIP scene and how people with virtually no VoIP experience can use Ruby and Adhearsion to write their first application in this generally foreign world of technology. If you’re building a Rails web application, with Adhearsion you could consider leveraging voice as a new, cutting-edge feature of it. If you’re a cowboy hacker with more personal ambitions, Jay will also talk about fun hacker projects and how you can go about implementing them. The world of voice is certainly a growing market and it can’t hurt to know a little about the technology!

- "Voice development on the fringe"
- "There's opportunity in the fringe"
- "Web development has this problem...it's saturated with innovation"
- Rails integration is a one-liner
- Asterisk's config file: complex and looooooong, app-specific config syntax
- Adhearsion's config: Ruby

Q&A
- Does it scale? Yes
- Asterisk breaks down at about 130 simul calls -- new box after that

Deployment Monoculture / Scaling Ruby Down (Dan Grigsby)

From the RubyFringe program booklet:

Most conversations about scaling Ruby web apps are pointed in the wrong direction. Instead of talking about whether Ruby can scale up — I think we all agree it can — I’d like to see it scale down.

As an entrpreneur, I launch dozens of ideas before I pick the one to turn into a startup. The Rails-inspired approach of deploying long running instances of the runtime, one or more per app, doesn’t scale down to support even a few side-by-side applications.

Instead of reflexively arguing that EC2 is cheap enough, this talk will challenge some base assumptions, take a hint and some inspiration from Google App Engine, and suggest another angle for deploying Ruby-based web apps.

- The programmer/entrepreneur lifestyle
    - Attractive
    - Hits the "sweet spot" -- lets you be who you are
    - It's all about controlling your own destiny
- The trick is to find opportunities to build stuff and match it with people who
  want that stuff

- Barrel research
    - It's a way of looking at markets and opportunities
    - Think of all the markets and opportunities out there as the volume
      within a barrel
    - Think of anything released into the market as a rock dropped into the
      barrel
    - The size of the rock in the barrel represents the size of the
      corresponding project or opportunity
    - Big rocks represent big projects taken on by big organizations
    - There are plenty of gaps between the big rocks, which can be filled in
      by smaller stones, representing smaller projects executed by smaller teams
    - It's fractal -- there are smaller gaps between the smaller stones, which
      can be filled in with sand, which represents even smaller projects by
      even smaller teams.

- The ideal team size these days: about 3
- Our current tools allow us to create well-crafted stuff with a small team
- Consider icanhascheezburger.com -- employs 9 people
- "Happy end of the Mythical Man-Month"
- If you're a hacker and have good hacker friends, you can do well

- With this in mind, what ideas should you implement?
    - "Late-bound ideas"
    - You want to make multiple, small, narrowly-focused bets
    - Act darwinistically -- take on a number of projects and cull those
      that aren't "fit to survive"

- Psychology and "Free"
    - Cheap is not free
    - Worry about spending money
    - Small psychological inputs can have a very large impact
    - Treat non-free things as dependencies -- try to get rid of them
    - Eliminating non-free things is part of a larger process:
      eliminating inefficiencies
    - If a customer is worth $100 -- Google will try to charge me $99 for it
    - Whoever your potential customer is, there'll always be someone out there
      who's going to spend more money than you trying to land that customer

- Disproportional Reward
    - This part of the talk is going to be all about market hacks,
      "fuzzing the market" and getting a result that is disproportionately
      greater than the time/effort/money you put in
    - They're all tech-driven: does not require you to be a salesperson
    - These approaches are tech- and marketing-based

    1. Breaking into the walled garden
        - PayMe.com was Pepsi to PayPal's Coke, with about 10% market share
        - We realized that auction buyers would be the big adopters of
          systems like ours, so we approached eBay who wouldn't take our ads
          because of an exclusive agreement
        - We found out that eBay had relationship with LinkExchange -- they sold
          a lot of ads in eBay
        - We bought out LinkExchange ads, many of which ended up appearing on
          eBay pages as per their arrangement, effectively doing an end run
          around eBay's refusal, getting out ads on their pages against their
          wishes
        - Exploiting this non-obvious relationship made our company successful

    2. Baby's Mamma
        - The parenting market has a strong geographic component: new parents
          tend to clump together in the same neighbourhoods
        - Certain postal codes are parent-rich
        - Going after parents? Find out where new schools are being built --
          that's where they are
        - School websites post which of their teachers are going on maternity
          leave -- send their colleagues coupons!
        - Take a page from the stalker book: use readily-available demographic
          information, sych as driver's licence registration, voter info
          registration
        - Do analysis on that information
        - Look for info that ties them to a specific demographic -- consider
          names that belong to specific generations, like "Hildegarde"
        - Use Freedom of Information Act requests
            - For example, Nate's dad gets an National Science Founation
              database of people who just got funding and uses it
              to cold call them
            - Often, he would be the first person to inform them that they
              got the funding, making him the bearer of good news and thus
              more likely to make the sale

    3. Tai Chi Marketing
        - I wrote a script to auto-fill contact forms that I knew would lead to
          my getting called by a telesales person
        - I got calls from telesales people, whose jobs are tough
        - I'd explain that I wasn't likely to buy what they were selling, but
          told them that I have a product that would make their job easier;
          could they introduce me to their boss?"
        - End result: an inbound sales call was redirected and turned into a
          sale to them
        - Making emotional connection with people is key

    "At this point in the list, we're now approaching that fine line that
    separates an entrepreneur from a criminal

    4. Dorm Spam
        - My first job: selling white box computers at dorms, a la Michael Dell
        - My major cost: shipping flyers
        - So I used the inter-campus mail system to send the flyers

    5. Tragedy of the Commons for Fun and Profit
    - This was in the era of desktop-based file-sharing clients like Scour,
      Kazaa and eDonkey
    - Shared a lot of windows media files with the names of popular videos and
      movies
    - .WMV files back then could include an instruction to pop open a browser
      window pointing to a specific URL when the file was played
    - We used this as advertising

Don't short this stuff:
- As programmers, we have a tendency to bury ourselves in coding when things
  get tough
- Some problems can't be solved with tech
- Learn about handling people

Rockstar Memcaching (Tobias Lutke)

From the RubyFringe program booklet:

Memcached is what makes the web fast. It’s also the simplest thing ever: you put a little memory aside for it, you put some keys in, you get them out at a later time.

So why the hell do all of you geniuses use it wrong? I’ll teach you how to tackle your performance issues using memcached once and for all.

- "I'm here to present the most boring talk of the entire conference"
- Memcached: "like a hash with Alzheimer's"
- Originally for LJ ("which is about people cutting themselves)
- Lots of people use memcache

- How does memcached work?
- Talking to servers
    - Simple protocol: get, set, delete
- What do you store in it?
- Object caches
    - after save to database, save it to cache

Living on the Edge (Yehuda Katz)

From the Rubyfringe program booklet:

Ruby is growing up quickly, and a number of Ruby’s mainstays are falling by the wayside. I’m talking about classics like Rails, Rake, Rdoc and much much more. This talk will help you squeeze even more developer productivity out of the latest edge tools that will be the mainstays a year from now. Of course, living on the edge is a dangerous game, so I’ll cover how to sanely keep abreast of the latest and greatest without having to spend all your time keeping your tool chain up and running.

I intend to cover Merb and DataMapper (briefly, as they are rapidly reaching escape velocity from the Land of Edge), Thor, YARD, basis and Johnson. I will also cover other edge tools that are released between time of printing and Rubyfringe. Rock on!

1. Merb
- Not really edge anymore, but still worth playing with
- Monolithic-ness not everything it's cracked up to be
- Merb lets you pick and choose
- Large community
- Stats: "I don't have numbers, but this is real!"
- You probably want to use Merb off edge
- Sake:
    - Does all the work cloning multiple git repositories

2. DataMapper
- NonSQL things
- Hard to get set up
- You should be using Github -- see github.org
    - "It's pretty much where Ruby edge is at"

3. Sake
- Lets us set up tasks

4. Thor
- Rake + Sake + Optparse

5. YARD
- Bigger than just an RDoc replacement

6. Johnson
- Rhino for Ruby
- A full Ruby-JavaScript bridge
- Lots of support for JavaScript expressions
- What's it for?
    - Server-side JS
    - Templates that work on client and server
    - Browserless tsting, potential
    - Optimizing Ruby?

Testing is Overrated (Luke Francl)

From the RubyFringe program booklet:

Develper-driven testing is probably the most influential software development technique of the last 10 – 15 years. There’s no question that it has improved the practice of building software. And in a dynamic language like Ruby, it’s hard to get by without it. But is it really the best way to find defects? Or is the emphasis on testing and test coverage barking up the wrong tree?

- Testing is a programmer's solution to the problem of bugs
- Coding's what we do, so why not make the solution out of code?

- What's wrong with this?

    1. Testing is hard
        - Developers tend to write clean tests describing the normal execution
        - Tend not to write "dirty" tests, which check non-normal cases, such as
          out-of-bounds conditions, bad data, various error states
        - Mature orgs write more dirty tests

    2. You can't test code that's not there

    3. Tests have bugs
        - A number of studies have shown that tests are just as likely to have bugs
          as the code they're testing
        - Who tests the tests?
        - There's also the matter of developers who comment out tests
          just in order to "get stuff done"

    4. Developer testing isn't very good at finding defects

- Complements to developer testing

    1. Manual testing
        - A good tester is worth his/her weight in gold
        - A good tester I know is not only good at explaining how the bug
          occurred, but also very thorough about providing info about it,
          including the stack trace
        - Have testers do it rather than programmers --
          besides, programmers hate it
        - Testers are also responsible for verifying fixes -- don't take the
          programmer's word that the bug has been fixed, confirm it!

    2. Code reviews
        - A good measure of code quality is the number of "WTFs per minute"
          during the code review
        - The polite code review definition of "WTF" is "What is this function?"
        - There are sociological considerations for code reviews -- you are,
          after all, leaving your creation (and by extension, you)
          open to criticism
        - Try to find bugs, not rip your collegaues to shreds
        - Code reviews can motivate you to code better
        - Can code reviews make better developers? Possibly:
          consider Robert Glass' argument that reading code
          can help make you a better developer

    3. Usability testing
    - Fun and easy
    - Jeff Atwood: Usability test failure is the ultimate unit test failure
    - The cheap way to do usability testing is to follow the model of
      Steve "Don't Make Me Think" Krug's "Lost our lease" usability lab:
      the testing computer and a camera, with you following the user
      through your application

- "Don't get me wrong: I write tests, I'm just not fanatical about it"
