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.

[LINK] Fluid Inconsistencies

Front-end developer Steffan Williams of Gridinator fame digs into some of the rendering inconsistencies across various browsers when dealing with percentage-based widths. Now, I don’t think this is a real problem for flexible, grid-based layouts or properly responsive designs. Some of these rounding issues won’t necessarily manifest themselves in your work, or at least not quite as noticeably.

I was, however, emphatically raising my fist in the air when I read this:

While I’m well aware that things don’t have to look the same in every browser, it just seems to strike me as odd that CSS3 features keep getting touted on the front of browser homepages, and yet something as fundamental as a percentage would be rendered incorrectly (or, rather, not as well as would be expected).

Emphasis mine. Much of the behavior Steffan notes was outlined by John Resig in 2008, nearly three years ago. There are some incredible inconsistencies at play here, and designers really shouldn’t have to shoulder the burden of working around them.

In short, some broad consensus between the different rendering engines needs to be reached—and if it comes at the expense of pushing the Next Hot Bleeding-Edge Experimental Sexy CSS3 Feature™ to market, I’m all for it.

But this blog goes up to eleven

So that Trent Walton went and redesigned his blog. And it is responsive. And on top of all that? It is sexy.

I’ve been admiring the Paravel team’s work for some time, and especially their dabblings in responsive design; if you haven’t seen the Do Lectures site, give it a whirl. It’s visually and technically impressive, and is a joy to browse at any resolution.

But that’s not all: given Trent’s penchant for full-width, type-heavy headings, he and the team at Paravel decided to knock out FitText, a jQuery plugin to create full-width, scaleable headlines from, well, your headlines. I can’t wait to give this a whirl.

Of course, in the middle of this cornucopia of goddamned fantastic things, Trent has to go and drop beats like this:

My love for responsive centers around the idea that my website will meet you wherever you are—from mobile to full-blown desktop and anywhere in between.

Emphasis mine. That sentence—that sentiment—is so good, I want it tattooed on my knuckles.

(Hrm. Wonder if there’s a jQuery plugin for that.)

All about Contents.

There are people you just need to say “yes” to.

I consider myself fortunate to have known and worked with Erin Kissane for years, and I’ve admired her writing for quite some time before that. Krista Stevens has been a friendly fixture throughout my career; she used to run an impossibly tight ship at Digital Web, where some of my first articles were published, before doing wonderful and incredible things at A List Apart. So yeah, when they asked me to work with them on their New Secret Project©, I basically signed up before they could finish telling me what it was all about.

And with that, I’m thrilled to announce that Contents, a new magazine focusing on content strategy, will be launching this fall.

Here’s Erin’s introduction:

The conversation about content strategy, online publishing, and all the subfields and specializations that surround them is flourishing. Wonderfully, it’s no longer possible to keep track of the posts, comments, talks, and events that take place every week within our world. And it’s not just that we’re voluble: our community is extraordinarily generous with knowledge, help, and professional support.

After benefiting from this conversation in so many ways, we’d like to give something back. A bounded collection of ideas and connections. A place to catch up with the movement of our fledgling industry and the much older fields from which it emerged. An editorial lens.

As a designer-person who benefitted immensely from Erin’s and Kristina’s respective books on the subject, this is all music to the ol’ ears. Because I think Contents is going to be a wonderful, oh-so-valuable resource for those of us looking to better understand content strategy (myself included), and I’m excited to contribute a little bit to making that happen.

In short: because of folks like Erin, Krista, and the oh-so-capable Erik Westra, I know Contents will be something special. You should check us out on Twitter, and maybe contribute an article or eight if you’re so inclined.

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.
