New treatment option for young women with hormone-sensitive breast cancer

A drug used for treating breast cancer, known as exemestane, is more effective than a common breast cancer prevention drug, tamoxifen, in preventing breast cancer recurrence in young women who also receive post-surgical treatment to suppress ovarian function. The combined results of the Tamoxifen and Exemestane Trial and Suppression of Ovarian Function Trial were presented at the 2014 ASCO Annual Meeting in Chicago.

The AEA 2011 schedule is here!

As I’ve said before, speaking at An Event Apart is a wonderful, terrifying experience. Wonderful because of, well, the insane caliber of the speakers—imagine taking some of the most fiercely intelligent designers, developers, and thinkers working today, and giving each of them an hour to talk about whatever most excites them about the web. And it’s terrifying because of, well, see above: standing shoulder to shoulder with the likes of Nicole, Dan, Aarron, and of course Jeffrey and Eric is, you know, slightly nerve-wracking.

Being part of this year’s road show has been one of the highlights of my career, traveling through five cities with my web heroes: the audience is fantastic, the speakers consistently wonderful, and I’ve learned something new at each show. Naturally, I’m excited and thrilled to be part of AEA’s newly announced 2011 lineup. I’ll be taking the stage in Boston, and then co-leading another installment of A Day Apart alongside Jeremy Keith. Hope to see you there, whether this year or next!

[LINK] Responsive images

Since striking out on my own, much of my time’s been dedicated to, well, the book. But I’ve also been fortunate enough to collaborate a bit with Filament Group on one of their projects: namely, a large-scale engagement that requires a responsive approach.

Needless to say, I am having the time of my life.

We’re also learning a lot, too. A lot of discussions about approach and execution have come up, largely because processes for a lot of this stuff don’t exist yet. That will, with a bit of hard work and community discussion, change over time. Still, there has been a lot of brilliant stuff created so far.

Here’s just one example:

The goal of this technique is to deliver optimized, contextual image sizes for responsive layouts that utilize dramatically different image sizes at different resolutions. Ideally, this approach will allow developers to start with mobile-optimized images in their HTML and specify a larger size to be used for users with larger screen resolutions — without requesting both image sizes, and without UA sniffing.

Check out the script, download it, and kick the tires a bit—feedback and tweaks are most welcome.

I realize that there are always going to be philosophical differences around responsive web design. But for me, the solutions-driven discussions are always going to be infinitely more interesting to me than the alternative.

On Presto

These thoughts aren’t especially well-formed, and/as I haven’t had my coffee yet.

So with that disclaimer out of the way, I have to say I’m a bit disappointed to hear Opera’s news: namely, that they’re abandoning their browser’s Presto engine, and adopting WebKit/Chromium instead.

Other folks far, far smarter than I have already weighed in. And don’t get me wrong: I’ve had my fair share of gripes with various bugs in Chromium (especially recently), but it’s a fantastic piece of software; as a friend said recently, ten-years-ago-me would’ve killed to have browsers as fine as we do now.

But right now, what I’m most worried about is the lack of diversity: four rendering engines is not exactly a large number, and going to three is a significant shift, if not an outright loss. Additionally, I worry we’re already facing a rather “well, it works with -webkit, so why worry about anything else?” mentality, which is something we’ll have to work harder to combat. Especially with an engine as fragmented as Webkit.

Of course, since the news is all of, like, minutes old, this is all speculation. Hell, it’s not even that: this is all just a pre-caffeine ramble, and not an especially well-formed one at that. I will say that Bruce’s take leaves me feeling hopeful. And I hope he’s right, and I’m wrong to be a bit disappointed. But right now, I know there’s one less (fantastic) rendering engine in active development, and that makes me a little sad.

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.
