  Bionic Office

Well. That took rather longer than expected. We have, finally, moved, into the new Fog Creek office at 535 8th Avenue, officially ten months after I started pounding the pavement looking for a replacement for my grandmother's old brownstone where we spent our first few years, working from bedrooms and the garden. Most software managers know what good office space would be like, and they know they don't have it, and can't have it. Office space seems to be the one thing that nobody can get rig...

  Prototypes and Inheritance in JavaScript

Forget everything you know about object-oriented programming. Instead, I want you to think about race cars. Yes – race cars. Recently I was watching the 24 Hours of Le Mans –a popular racing event in France. The fastest cars in the race are the Le Mans Prototypes. Although these cars are built by car manufacturers like Audi and Peugeot, they are not cars you’ll see on the streets and highways of your home town. They are built exclusively for high-speed endurance ra...

  JavaScript's Two Zeros

JavaScript has two zeros: -0 and +0. This post explains why that is and where it matters in practice. The signed zero Numbers always need to be encoded to be stored digitally. Why do some encodings have two zeros? As an example, let’s look at encoding integers as 4-digit binary numbers, via the sign-and-magnitude method. There, one uses one bit for the sign (0 if positive, 1 if negative) and the remaining bits for the magnitude (absolute value). Therefore, -2 and +2 are encoded as f...

  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...

  Publish Your Go Package on pkg.go.dev

go.dev is a site where various resources for Go developers are shared, such as “Get Started”, Tutorial, Packages (pkg.go.dev), and all the official blogs. Among them, Packages is where I visit most, which allows free access to all the open-source Go packages submitted by communities including the native Golang packages. Thanks to all the contributors, I enjoy the great benefit, and sometimes I want to be a contributor myself. Let’s submit a “complete” package t...

  The 15 Golden Rules of UI design and flow.

Last night a good friend of mine showed me the latest Need for Speed game on the iphone / ipad. Quite an impressive feat of rendering and a relatively good game to boot. However, the front end, wow, a classic case in UI mis-engineering. Loads of stats, pages and pages of bits and pieces to wade through – a classic case of over stimulating the player with lots of decisions they have no business making – stuff that will significantly change their game play experience but being...

  Ajax file upload tutorial

Step 1 - AJAX file uploadAJAX file upload tutorialFirst of all I have to say that to create a pure AJAX file upload system is not possible because of security limitations of JavaScript. All of the Ajax upload systems I know use some third party tool/package or only mimics the AJAX feeling. Even so it makes file upload process a bit nicer. In the next section I will present you a solution which imitates the AJAX process, but uses a normal upload process and iFrames.The concept: Create a simp...

  Speed Hashing

A given hash uniquely represents a file, or any arbitrary collection of data. At least in theory. This is a 128-bit MD5 hash you're looking at above, so it can represent at most 2128 unique items, or 340 trillion trillion trillion. In reality the usable space is substantially less; you can start seeing significant collisions once you've filled half the space, but half of an impossibly large number is still impossibly large. Back in 2005, I wondered about the difference between a checksum and...

  10 Tips To Make Your C Program Effective

The beauty of any code lies not only in finding the solution to a given problem but is in its simplicity, effectiveness, compactness and efficiency( memory ). Designing the code is harder than actually implementing it. Hence every programmer should keep a couple of basic things in mind while programming in C. Here we introduce you to such 10 ways of standardizing your C code. 1. Avoid unwarranted function calls Consider the following two functions: view source print? 1 void str_print( c...
