  Hash Tables in Javascript

IntroductionHash tables are a permutation of associative arrays (i.e. name => value pairs). If you use PHP, then you are very familiar with this type of data structure already since all PHP arrays are associative.The Javascript language implements very loose and somewhat limited support for associative arrays. Any JavaScript array can use other objects as keys, making it a hash, but there exists no formal constructor for initializing them and it is more or less unweildy to work with. A short ...

  The problem isn’t you. The problem is the problem.

A friendly reminder: The problem isn’t you. The problem is the problem. –Steven Pressfield Some stuff is just hard. We start thinking we messed up. That it’s an issue with us. But it’s not. The work is hard and the problem is hard. You need to solve the problem, not fix yourself. The quote above is from Steven Pressfield’s incredible Do the Work. The audiobook (that’s a store link) is about 90 minutes long, so it fits in a s...

  My life as a freelancer

In the summer of 2006 a work buddy, George, has told me that I could make some extra money programming on a site named Rent A Coder. I’ve signed up the same day. After losing some time on a project that never started I lost my interest in “coding for money”. I almost forgot about RAC.Fast-forward two years, I was a PhD student at a small North American University with a student visa and … nothing else in my pockets. For a few months I was able to make a living from ...

  Do You Morph Into A Different Programmer?

Every experience you have as a software developer should change you in some way. And I don’t just mean growing older by virtue of time passing. Everything you do should evolve your understanding of your craft (and/or related skills) or your understanding of yourself – which ultimately achieves the same goal. I am not just talking about major milestones in your software development career like switching jobs, becoming a leader/manager or starting you own company. Every job, ev...

  Why Dynamic Programming Languages Are Slow

In a statically typed language, the compiler knows the data-type of a variable and how to represent that. In a dynamically-typed language, it has to keep flag describing the actual type of the value of the variable, and the program has to perform a data-dependent branch on that value each time it manipulates a variable.  It also has to look up all methods and operators on it. The knock-on effect of this on branching and data locality is lethal to general purpose runtime performance. T...

  Selling Yourself: Why? and How!

I know many good developers who are under the impression that they either don’t have to sell themselves, or selling themselves is wrong, but is that really true?First let me clarify by defining what I mean by “selling yourself”. I don’t mean “selling out”, I mean marketing yourself, what you’re doing and what your skills are. Especially to your organization.I don’t need to sell myself, my code speaks for itself.Really? Do you think your pristin...

  Android Hardware Buttons are not broken, let me tell you why

This post is written as a reaction on Christoffer Du Rietz’s article The Android Hardware-Buttons Are Broken. In his article Christoffer explains how the Android back button shows inconsistent behavior like doing different actions when it is used on the same screen.In the following article I will try to explain that this behavior is not broken. Instead it is exactly what the Android developers had in mind while designing the back button behavior.The way the back button is broken according...

  How the Internet Is Ruining Everything

The ongoing argument about whether the Internet is a boon or a bust to civilization usually centers on the Web’s abundance. With so much data and so many voices, we each have knowledge formerly hard-won by decades of specialization. With some new fact or temptation perpetually beckoning, we may be the superficial avatars of an A.D.D. culture.David Weinberger, one of the earliest and most perceptive analysts of the Internet, thinks we are looking at the wrong thing. It is not the co...
