[LINK] A new design for Mark Boulton

Words to tattoo on your knuckles:

Over the past couple of years, my blog hasn’t felt my own, to a degree. It’s felt like I’ve been writ­ing for an audi­ence, post­ing stuff for oth­ers rather than myself. That’s arse-backwards. A blog should be about per­sonal expres­sion. The moment you start think­ing, and writ­ing, to please oth­ers then it’s a bind; it feels less like a per­sonal exer­cise and more of a job.

A beautiful, thoughtful redesign from Mark Boulton (and a responsive one at that). Go go, read read.

OS X, hidden wireless networks, and me

Having a bit of a problem with my laptop lately, and thought I’d write up the problem in case it’s affecting anyone else:

So my MacBook Air (mid-2009, OS X 10.8.3) When my computer wakes from sleep, it doesn’t immediately reconnect to my wireless network. What’s more, if I open up the wireless menu in OS X’s menu bar, it doesn’t show any networks nearby. Zip. Zero. Zilch. It’ll scan for new networks repeatedly, but won’t see a single one.

But here’s where this gets really, really annoying: if I open the Network panel in System Preferences, all nearby networks are immediately visible without delay.

Given the weird inconsistency between the two menus, and that I can reproduce this issue consistently, I figure this is a bug: either with 10.8.3, or with my aging little laptop. Either way, I’d love to fix it. So if you’ve come across this problem and know how a workaround, suggestions via email or Twitter would be most welcome.

Update: Charles Gaudette suggested on Twitter that it might be a couple , and pointed me toward a page showing how to clear out corrupted plist files. Deleting the com.apple.network.identification.plist and com.apple.airport.preferences.plist files seems to have done the trick—thanks, Charles! And thanks to everyone else who wrote in or twittered suggestions at me.
