10 reasons my O(n²) algorithm is better than your O(n) algorithm
about 1 year ago - No comments
OK, so it’s a controversial title, but the point I want to make is that programmers often get confused about the time complexity, i.e. order O() of an algorithm and performance. They will happily declare that their O(n) algorithm is so much better than someone else’s O(n²) algorithm as they rip out some simple, stable, More >

A better Tail program for Windows
about 2 years ago - No comments
‘Tail’ is a program that monitors the end of a log file, keeping the view at the end of the file. In the past I’ve used MTail to monitor log files but recently I switched to Baretail because it does a better job at monitoring multiple log files at the same time.
Shaving seconds off page load times

IIS6 comes with some antiquated settings for Gzip compression. Even after enabling it in the IIS management console nothing happens until you edit the metabase file to enable the files you really want to compress. With the correct settings the main page for my site now loads in 5.3s instead of 6.0s and subsequent loads More >

Javascript error reporting
about 2 years ago - No comments
It’s all very well to be capturing all the errors that happen server side, logging them to a database and reporting on them like any robust web service ought to, what about the client? So today I added reporting for client-side errors to the project I’m working on. Turned out to be remarkably easy. A More >
Optimization Advice
about 2 years ago - No comments
Optimization is the root cause of much unmaintainable code. It is also the root cause of many bugs. My advice to the vast majority of programmers is to stay away from it: if you have a good architecture you should not need to optimize it at this level. Personally I divide optimization into three buckets: More >
It’s all about disk speed
about 3 years ago - No comments
Recently I upgraded to a 10,000 rpm drive in my desktop and a 7,200 rpm drive in my laptop. Quite frankly this is the most cost effective way to improve performance on any machine. CPU speeds have grown dramatically over the last few years, so has memory capacity and CPU to memory bandwidth, but disk More >
Comcast woes and a new monitoring utility
about 3 years ago - No comments
I’ve been having lots of problems with my Comcast connection this week, rather than calling the Comcast support department to receive the usual ‘turn your PC, router, model off, now turn them back on, did that fix it?’ response I decided to do some more investigation. I was able to easily hook up the modem’s More >
