  Opinion: Top 5 Things I Wish Someone Told Me Before I Started My Own Business

1. However much money you think you'll need to start a business, you should take that number and double it I thought I had strategically planned every penny when I first started, but I had no idea that there would be so many unanticipated costs. Since we have a home office, I use temporary commercial office space and conference solutions for meetings and demonstrations. We always like to buy lunch for our clients, and we like them to lunch well. By the time everything is factored in, depen...

  Cache them if you can

“The fastest HTTP request is the one not made.” I always smile when I hear a web performance speaker say this. I forget who said it first, but I’ve heard it numerous times at conferences and meetups over the past few years. It’s true! Caching is critical for making web pages faster. I’ve written extensively about caching: Call to improve browser caching(lack of) Caching for iPhone Home Screen AppsRedirect caching deep diveMobile cache file sizesImproving app ...

  Efficiency of code execution

If you want to optimize your program codes, you need to find their Hotspot, i.e, the codes which are executed most frequently. If you can optimize this portion of codes a bit, you may gain much improvement of your code efficiency. Here I give you three examples about efficiency of code execution.1. PHP's Getter and Setter (From Reddit)This example a quite simple, you can skip it if you want.Consider the code below, we can find it's slower when we use Getter/Setter method to read a member variabl...

  Good ways to "insult" a computer scientist

Computer scientists are a group of people who are hard working and talented. They build the theory foundation for information and computation and they usually work on something difficult to understand. Many computer algorithms are created by computer scientists. In our mind, they are those people we admire most. But sometimes we also want to make fun of them or "insult" them. What are good ways to "insult" them? Here we share some. Ask him to make a website for you...and with PHP. Ask them why ...

  Dart is to JavaScript as C# is to C++

Given the background of Lars Bak, the Google engineer whose V8 JavaScript interpreter upended Firefox's claim on speed, it was reasonable to suspect Google's new Web development language might look a lot like Smalltalk. But that might have taken the Web in a strange and different direction. Today, on the day of a Web developers' conference in Denmark, Google and members of the Chromium open source development team raised the curtain on Dart, the company's bid for a new and somewhat more str...

  API Design is UI for Developers

I’ve been thinking a lot about APIs and their design recently.I stumbled on this fantastic quote from Greg Parker: A programming language is a user interface for developers. Language authors should learn from HCI principles.22/02/2012 19:10 via webReplyRetweetFavorite@gparkerGreg ParkerWhen I first started learning C++ (back in the bad old days) I was convinced that any 1st year student could design a better programming language. One which behaved in a sane fashion without a lot of le...

  The "C is Efficient" Language Fallacy

I came across an article yesterday about programming languages, which hit on one of my major peeves, so I can't resist responding. The article is at greythumb.org, and it's called Programmer's rant: what should and should not be added to C/C++. It's a variation on the extremely common belief that C and C++ are the best languages to use when you need code to run fast. They're not. They're good at things that need to get very close to the hardware - not in the efficiency sense, but in the...
