Here are a few questions that will tee us up for a good conversation:

- Can you tell me about your project in a few sentences? 
- What’s the timeframe? Does a certain event depend on this project launching?
- What are you looking for from us? Do you want us to design, build, and launch the whole site? Or do you have developers or other partners lined up and only need us for design?
- Have you already started on any part of the project? Do you have existing work? A new logo? Some rough designs or ideas for the site?
- How large is your team? What are the roles you envision on your end?
- How did you hear about our work? What specifically interests you about it? Any projects that you’re keen on?
- How much money have you set aside for this project?
- Are you talking to others about this project? Might we ask how many? What do you like about their work?

C++ Pointer Tutorial

Because pointers can be ugh

"Regular" variables (not pointers)

To understand a pointer, let's review "regular" variables first. If you're familiar with a programming language without pointers like JavaScript, this is what you think when you hear "variable".

When declaring a variable by identifier (or name), the variable is synonymous with its value.

  product_preview: {
    product_type: '',
    media_items: [
      {id: 0, url: 'my_url'}, 
      {id: 1, url: 'my_url'},
      {id: 2, url: 'my_url'}
    ],
  },
});

Around 2006-2007, it was a bit of a fashion to hook lava lamps up to the build server. Normally, the green lava lamp would be on, but if the build failed, it would turn off and the red lava lamp would turn on.

By coincidence, I've actually met, about that time, (probably) the first person to hook up a lava lamp to a build server. It was Alberto Savoia, who'd founded a testing tools company (that did some very interesting things around generative testing that have basically never been noticed). Alberto had noticed that people did not react with any urgency when the build broke. They'd check in broken code and go off to something else, only reacting to the breakage they'd caused when some other programmer pulled the change and had problems.
