I’m going to want to remember this one day, so here’s a pointer to Rob Wilderson’s Ignore Changes to Tracked Files in Git.

I’m especially going to want to remember the bit about how to find which files I’ve ignored in this way.

SVN tree conflicts can be insanely annoying – especially when they occur because you’ve deleted something locally and then an incoming change also deletes it. They can also be hard to resolve from most IDEs.

The trick is to resolve them from the command line.  Edit/create/delete the files to get things into the state they should be and then from the command line run:

svn resolve --accept working <path>

No more tree conflict.

CSS3 makes it trivial to have alternating row colours for tables, but when the table is in a fixed height scroll panel, it’s much more difficult to have those alternating row colours extend beyond the bottom of the table content to fill the available space. Here’s the approach I use.

First let’s start with a simple table with alternating colours in a scroll panel:

That gets us alternating row colours where there is table content. To get it to extend beyond the table content we need to add a filler row:

I keep forgetting this so for the record, you can use SSH to round trip data out to a remote server and back to your own box.  This is most useful for adding latency and bandwidth limitations to a connection when doing website testing.  The trick is to use both local and remote port forwards:

ssh -L 9090:localhost:9091 -R 9091:localhost:80 remote.server.com

The -L argument starts listening on port 9090 locally and sends all that traffic to port 9091 on the remote server (the domain name, localhost, is resolved by the remote server so it refers to the remote server, not your local machine).  Then the -R argument listens on port 9091 of the remote server and forwards all that traffic back to your machine’s port 80 (here localhost is resolved on your local machine).

Recently I’ve been getting spam from the “standards organisation” OASIS inviting a company that I don’t work for1{#footlink1:1327526703777.footnote} to join a new standards initiative. There’s no pretense that I’m being invited because of my clearly superior knowledge of the area involved, merely that the company could get great advertising exposure by participating – including being listed on a press release! Naturally we’d need to become OASIS members and pay the appropriate fee, and to be in the press release you’d have to be at minimum a “sponsor level member”.

HTML 5 Boilerplate reminded me of an old-school tool which is extremely useful for concatenating JS and CSS files on the fly – server side includes:

<FilesMatch ".*\.combined\.(js|css)$">
  Options +Includes
  SetOutputFilter INCLUDES
</FilesMatch>

Then you have a main scripts.combined.js (or css) which contains:

<!--#include file="libs/backbone-min.js" -->
<!--#include file="libs/underscore-min.js" -->
<!--#include file="libs/jquery-1.7.1.min.js" -->

Plus any other files you need, in the order you specify. This works great for development mode so you can change a file on the fly and just refresh the browser without running any kind of build script. When it comes time to push to production, it’s easy for a build script to process the file ahead of time and be confident that you’ll get exactly the same result.

This evening I stumbled across two interesting posts about alternate layouts for pairing rather than sitting side by side. Firstly Tom Dale talking about Tilde’s corner desk pairing setup (and some of the software setup they use) and that was inspired by Josh Susser’s face to face pairing setup at Pivotal Labs.

Both approaches require more floor space which makes them difficult to setup but I would expect the face to face pairing to be a heck of a lot better if done well. I’ve always preferred having separate screens in mirror configuration as well as separate keyboards and mice to allow the developers to sit a little further apart to be comfortable and to be able to look straight ahead at the screen. That said, I quite like having a second monitor for spreading out windows as we have at LMAX so it’s not clear cut which is better.

Yan Pritzker recently posted “5 ways to get insane productivity boosts for coders” which provides some good tips on how to improve your usage of tools when doing technical work. To summarise:

• Never look when you can search
• Don’t repeat yourself (by setting up shortcuts and command line aliases)
• Learn a scripting language
• Learn an editor (and use that editor everywhere)
• Learn regular expressions

However, nearly all of these tips really boil down to how to be more productive at writing text and the mechanics of writing code – editing actual source code files, jumping to different places in those files, executing commands more efficiently etc. Are these really the tasks that consume the vast majority of a developers time?

If you’re experiencing an issue when using Chrome with Google Maps where typing in a location and hitting enter either does nothing or just says “Loading…” forever, you’ve very likely hit upon a bug in the Skype click-to-call extension.

Skype automatically installs this “add-on” when you install Skype and it adds links to phone numbers so that you can click them to call on Skype. Unfortunately, Google Maps seems to be triggering a bug in the extension and so it is either corrupting the data returned to the Google Maps javascript or just preventing the request from ever returning.

Following on from my last post, Jason Adam Young has some excellent advice to help you continually get better and better and building software and perhaps more importantly, be more and more valuable to whoever you happen to be working for.

This afternoon during an interview, a potential new hire at LMAX asked what LMAX could offer in the way of career progression. Since I’ve been thinking a fair bit about what comes next in my career now that I’m moving back to Australia I thought I had a pretty good answer and that it might be worth sharing here2{#footlink2:1323196996971.footnote}.

In most industries career progression is signified by ever fancier sounding job titles, but for a software developer, the fancier the title sounds the less likely you are to actually do any development. Essentially, career progression often amounts to career migration – into “architecture”1{#footlink1:1323196219398.footnote} or managements. If you really love developing software though you need to look at it a different way. If I spend the rest of my career as a “Senior Software Engineer” I’ll be pretty happy, so long as I can keep honing my skills and becoming more valuable to the companies I work for. Ideally I’d like the pay I take home to grow in line with that value.

After four years living in the UK, my wife and I have decided to move back to Australia mid-February 2012 to be closer to family. As such, I’m now starting to look at job opportunities back in Oz. If you’re hiring, I’d love to hear from you and discuss how we might work together. My CV is available online to give you an idea of my experience and of course the backlog of this blog shows some of my thinking and learning throughout the years1{#footlink1:1322426906768.footnote}.
