  JavaScript Attack/Defend

As developers and designers we work hard to build visually attractive, fast and easy to maintain applications. Our goals are to make sure the applications we build stick to users and keep them coming back for more. Security is not always at the forefront of our minds. No one intentionally builds insecure software but often a lack of security knowledge leads developers to build vulnerabilities into their applications. In this article we are going to examine two web security attacks, how they are ...

  Translating math into code with examples in Java, Racket, Haskell and Python

Discrete mathematical structures form the foundation of computer science.These structures are so universal that most research papers in the theory of computation, programming languages and formal methods present concepts in terms of discrete mathematics rather than code.The underlying assumption is that the reader will know how to translate these structures into a faithful implementation as a working program.A lack of material explaining this translation frustrates outsiders.What deepens that fr...

  Get vs Post in HTML form

In HTML, one can specify two different submission methods for a form. The method is specified inside a FORM element, using the METHOD attribute. The difference between METHOD="GET" (the default) and METHOD="POST" is primarily defined in terms of form data encoding. The official recommendations say that "GET" should be used if and only if the form processing is idempotent, which typically means a pure query form. Generally it is advisabl...

  Kubernetes Authentication & Authorization 101

If we want to build a system with user modules, Authentication and Authorization are something that we can never ignore, though they could be fuzzy to understand. Authentication (from Greek: αὐθεντικÏŒς authentikos, “real, genuine”, from αὐθέντης authentes, “author”) is the act of proving an assertion, such as the identity of a computer s...

  A Python Optimization Anecdote

Hi! I’m Pavel and I interned at Dropbox over the past summer. One of my biggest projects during this internship was optimizing Python for dynamic page generation on the website. By the end of the summer, I optimized many of dropbox.com’s pages to render 5 times faster. This came with a fair share of challenges though, which I’d like to write about today:The ProblemDropbox is a large website with lots of dynamically generated pages. The more pages that are dynamically generat...

  Don’t Call Yourself A Programmer, And Other Career Advice

If there was one course I could add to every engineering education, it wouldn’t involve compilers or gates or time complexity.  It would be Realities Of Your Industry 101, because we don’t teach them and this results in lots of unnecessary pain and suffering.  This post aspires to be README.txt for your career as a young engineer.  The goal is to make you happy, by filling in the gaps in your education regarding how the “real world” actually works.  ...

  Why Emacs?

PreludeIf you are a professional writer – i.e., if someone else is getting paid to worry about how your words are formatted and printed – Emacs outshines all other editing software in approximately the same way that the noonday sun does the stars. It is not just bigger and brighter; it simply makes everything else vanish.Neal StephensonIn the Beginning … Was the Command LineI’m an Emacs user and I’m proud of the fact.

  Signs that you're a bad programmer

1. Inability to reason about codeReasoning about code means being able to follow the execution path ("running the program in your head") while knowing what the goal of the code is.SymptomsThe presence of "voodoo code", or code that has no effect on the goal of the program but is diligently maintained anyway (such as initializing variables that are never used, calling functions that are irrelevant to the goal, producing output that is not used, etc.)Executing idempotent functions multiple times (...
