  Vim: revisited

I’ve had an off/on relationship with Vim for the past many years. Before, I never felt like we understood each other properly. Vim is almost useless without plugins and some essential settings in .vimrc, but fiddling with all the knobs and installing all the plugins that I thought I needed was a process that in the end stretched out from few hours to weeks, months even; and it the end it just caused frustration instead of making me a happier coder. Recently, I decided to give Vim ano...

  One thought about JavaScript exception handle

Due to network, browser and cache issues, the JS executed in production may produce different results from the testing environments. Sometimes they may produce exceptions.

  True Scala complexity

Update 2: Sorry for the downtime. Leave it to the distributed systems guy to make his blog unavailable. Nginx saves the day.It’s always frustrating reading rants about Scala because they never articulate the actual complexities in the core language.Understandable—this post is intended fill that gap, and it wasn’t exactly easy to put together. But there’s been so much resistance to the very thought that the complexity exists at all, even from on up high, that I thou...

  How expensive is a MySQL query?

Database access speed is always the bottle neck of many applications. Many application have large amount of data to search, retrieve and display nowadays.

Yunyang,Zhang from Nubee in Singapore did some research...

  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...

  Why Software Projects are Terrible and How Not To Fix Them

If you are a good developer and you’ve worked in bad organizations, you often have ideas to improve the process.  The famous Joel Test is a collection of 12 such ideas.  Some of these ideas have universal acceptance within the software industry (say, using source control), while others might be slightly more controversial (TDD).  But for any particular methodology, whether it is universally accepted or only “mostly” accepted, there are a multitude of o...
