I hate cut-and-paste
Me, I blame the IDE's.Coding used to be hard. Not because programming itself was overly hard, but mostly because editors absolutely sucked. How much the typical development environment in the 70's and 80's sucked is hard to convey (except for a very lucky few, and those would have likely been using DEC and WANG gear). I got in on the tail end of the punch card era. Punching your own program is lots of fun. Once. And if you drop a deck you get to play with the sorter, which is also lots of fun (o...

Guide to Clearing Storage Space on a Macbook
Macbooks are pretty notorious when it comes to what storage space you have available. Those few gigabytes that you have will disappear in no time if you are not careful. The whole issue becomes even more problematic for people who are not that familiar with Macbooks or have switched from another computer. And if you do not pay attention, it will not take too long before you have next to no storage space on the hard drive. Leaving only a few gigabytes of free space will significantly reduce the ...

Is The Cloud Finally Catching Up With Mighty Oracle?
Oracle for years has seemed impervious to cloud computing. First Larry Ellison dismissed it. Then he sort of touted it, his version at least. But all along, Oracle was growing nicely. The industry chatter didn’t seem to matter. Big companies buy big software systems. Something changed this winter. Oracle’s software license sales limped up just 2% in December, and the company blamed customer budget cuts and fears over the European debt crisis. Sales to Europe, Africa and...

The trap of the performance sweet spot
This post is about JavaScript performance but I would like to start it by telling a story that might seem unrelated to JS. Please bear with me if you don’t like C.A story of a C programmer writing JavaScriptMr. C. is a C programmer as you can probably guess from his name. Today he was asked by his boss to write a very simple function: given an array of numbered 2d points calculate vector sum of all even numbered points... He opens his favorite text editor and quickly types somet...

Why We Moved Off The Cloud
Cloud computing is often positioned as a solution to scalability problems. In fact, it seems like almost every day I read a blog post about a company moving infrastructure to the cloud. At Mixpanel, we did the opposite. I’m writing this post to explain why and maybe even encourage some other startups to consider the alternative.First though, I wanted to write a short bit about the advantages of cloud servers since they are ideal for some use cases.Low initial costs. Specifically, you...

Top 10 Tell Tale Signs Your Computer Has a Virus

As internet users increase so does the instance of com...

PHP: a fractal of bad design
Preface I’m cranky. I complain about a lot of things. There’s a lot in the world of technology I don’t like, and that’s really to be expected—programming is a hilariously young discipline, and none of us have the slightest clue what we’re doing. Combine with Sturgeon’s Law, and I have a lifetime’s worth of stuff to gripe about. This is not the same. PHP is not merely awkward to use, or ill-suited for what I want, or suboptimal, or...
10 Web Design Elements that You Shouldn’t Overlook
When it comes to designing and building websites, it never seems to happen fast enough.Given this fast pace, many small details that are eventually required to build the website are often left out of the design process. While these details might be minor, they are what take a website from nice to truly awesome.These details are often easy to miss because they don’t drive the overall look and feel of the website. The problem is that as your development team works through the design, it wil...
