Subject: [PATCH 2/5] fix: Make dummy variables available

Cobalt's liquid has been changed to fail on missing variables.  This
could be made less strict in the future.

This means that every page reusing a layout needs the variables defined,
even if it is to `Nil`.

So added

 tl;dr: Rust is a safe systems-programming language. But besides its guaranteed safety, it also rivals C/C++ in speed for some datasets.
 Let me show you the tricks that Rust make Rust fast, which are possible but very hard to pull off in other languages.
 I will talk about agressive compile-time optimizations, zero-cost abstractions, fearless concurrency, and more.

 Text files are the single most important way we can communicate with computers. It's no coincidence that they are also the most important way to communicate with other human beings. What we can achieve with text files is invaluable: Write it once and refer to it whenever you want to get the message across in the future. Write a program (it's just text), save it and let the machine execute it whenever you like. Write another text file which contains the rules for the execution of your program and the computer runs your program exactly as you specified (`cron` files do that on Unix).

 Back in University I worked on a project, which bridged the gap between Java and Haskell.
 It was a tool for teaching students the basics of computational geometry.

 This short article deals with a serious problem in software development: bit rot.
 When switching to a new platform (for instance from Windows XP to Windows Vista/7) the programmers need to make sure that old bits of code run flawlessly. There are several ways to achieve this goal that will be discussed during the next paragraphs:

 Text files are the single most important way we can communicate with computers. It's no coincidence that they are also the most important way to communicate with other human beings. What we can achieve with text files is invaluable: Write it once and refer to it whenever you want to get the message across in the future. Write a program (it's just text), save it and let the machine execute it whenever you like. Write another text file which contains the rules for the execution of your program and the computer runs your program exactly as you specified (`cron` files do that on Unix).
 
 Text files can be structured in any way you can possibly imagine. Some flavours are [JSON][3], [Markdown][4] and [SVG][5]. It's all just text. There exist literally a billion of programs and algorithms to access, modify and distribute text files. You can write them with *Emacs*, print them on a terminal, pipe them through *sed* and send them via email to a friend who publishes them on the web. Because text files are so important we have good support for them on any computing system. On Unix everything is a file and *HTML* is just structured text. It's a simple and powerful tool to make a contribution to society that outlasts our lifes.

 This morning I woke up to the beeping noise of our oven's alarm clock.
 The reason was that I tried to correct the oven's local time the day before &mdash; and I pushed the wrong buttons.
 As a result I didn't set the correct time, instead, I set a cooking timer... and that's what woke me up today.

 Recently, I tried to implement a binary tree data structure in Rust.
 Each binary tree has a root value, a left, and a right subtree.
 I started from this Python implementation, which is quite straightforward.

 When I was around 12, I set myself the goal to become a professional programmer.  
 I can tell, because at this time I made the conscious decision to use my right hand to control the mouse &mdash; even though I'm left-handed.

 Recently I came across a delightful article on idiomatic Ruby.
 I'm not a good Ruby developer by any means, but I realized, that a lot of the patterns are also quite common in Rust.
 What follows is a side-by-side comparison of idiomatic code in both languages.

 One common Systems Design task in interviews is to sketch the software architecture of a URL shortener (a [bit.ly](https://bit.ly) clone, so to say).
 Since I was playing around with Rocket, why not give it a try?

 People look confused, when I tell them about my passion for Algorithms and Datastructures.
 Most of them understand what a Programmer is doing, but not what Computer Science is good for.
 And even if they do, they think it has no practical relevance.

 Let me first point out the obvious: yes, the title is a little sensationalist. Also
 you might be asking why I should be entitled to talk about the future of Rust. After
 all, I'm neither part of the Rust core team, nor a major contributor to the Rust

 Programming has many faces. It is the science of structured thinking.
 It is the art of eloquent expression.
 It teaches you to be humble when you look at other peoples' fascinating work.

 I've written most of my code in dynamically typed languages such as Python or PHP. But ever since dabbling with [Rust](https://www.rust-lang.org), I've developed a passion for static type systems.  
 It began to feel very natural to me; like a totally new way to express myself.

 What's the simplest Unix command you know?  
 There's `echo`, which prints a string to stdout and `true`, which always terminates with an exit code of 0.

 Programming languages help us describe general solutions for problems; the result just happens to be executable by machines. Every programming language comes with a different set of strengths and weaknesses, one reason being that its syntax and semantics heavily influence the range of problems which can easily be tackled with it.
 
 **tl;dr:** *I think that functional programming is better suited for mathematical computations than the more common imperative approach.*

 What makes a great public speaker? He's passionate, knowledgeable, and a good storyteller. I strive to become better at all of that.
 Here are some of my recent presentations.
