Another Year Gone By

by Sean Carroll

Some people spend their holiday vacations catching up on reading, or spending time with relatives. I like to take a day and devote it to fixing up my web pages, which tend to get sadly neglected over the year. (The erratum page for my book is embarrassingly out of date, I really should fix that.) This year I sat down and made a list of my favorite blog posts ever, from the heady and innocent days of Preposterous Universe to the practiced maturity of the blog you see before you today. Actually I tended more toward the “potentially useful” than simply my favorites. I think the Anatomy of a Paper series was the best of this year — much of my recent blogging has been of the short throwaway variety, but occasionally I work up the energy for something more substantive.

Interestingly, I still don’t know what to think about blogging in general. I read them all the time, and can’t seem to stop myself from posting even when things get busy. (It’s the quality that deteriorates, not the quantity, it seems.) But the technology is still quite new by any sensible standards, and the kinks have yet to be worked out. In the blogs I read, there seems to be some degree of shaking-out going on — the more successful blogs are ones where there are at least a couple of posts every day, and that’s a hard rate to keep up. It either means that you become a professional blogger, or at least a semi-professional for whom blogging takes up a majority of your attention. (As already admitted, I can’t seem to stop blogging, but at the same time I can’t really imagine devoting more than half an hour a day or so to the practice.) And very few people, of course, have quite so many novel and interesting things to say, so we find a lot of repetition or reacting to stories generated elsewhere. Some of the more casual and informal voice of the earlier days may be being lost. There’s no necessary reason for this, given the easy access to newsreaders like Bloglines or Google Reader — one could certainly imagine subscribing to an eclectic collection of provocative and unpredictable bloggers who only post a few times per month. But how do you find them? I think there’s a great opportunity out there for clever aggregators, who can figure out an efficient way to collect the best of what is already going on throughout the blogs and bring it to the appropriate readers.

Science blogging, I think, still has yet to find its comfort zone, despite the growing numbers of impressive science bloggers. There are important questions about how to you conceive of your audience, the best way to conduct research discussions in a public forum, and how to deal with comments generally. We’ve talked a little bit about this before — here, here, here — but I think this is a conversation that is very much ongoing. A sadly effective demonstration of the difficulties can be found in the Garrett Lisi thread, where everyone (including me) got snippy and annoyed at everyone else. The real problem there, in my judgment, was not the occasional bits of rudeness or nonsense, but the insistence on responding to the rudeness and nonsense, making the thread about the meta-conversation instead of sticking to the actual conversation. It’s pretty elementary internetology that the best way to deal with low tone is to raise the tone by being relentlessly high-minded, but that’s a strategy that requires almost everyone to go along for it to work. Or to have someone who is willing to spend their time carefully moderating hundred-comment threads, which our blog doesn’t have. Of course we could be very dramatic, requiring that commenters register, or disallowing anonymity entirely. Those sound like drastic steps that would likely change the feel of the blog beyond recognition. In any event, we’re still trying to balance our goals of conducting interesting conversations about ideas in a public forum, without actually spending much time on it — we’ll see how it goes.

And we have a Facebook group. Still don’t know what to do with that, but it’s great to see pictures of some of our regular readers. Happy New Year to all!

Presidential Poll

by Sean Carroll

Just curious about how easy it is to set up a poll. Why not find out toward whom the CV readership is leaning these days? We promise your answers are not binding.


Who is currently your favorite candidate for the 2008 Presidential elections?
Hillary Clinton (D)
John Edwards (D)
Rudy Giuliani (R)
Mike Huckabee (R)
John McCain (R)
Barack Obama (D)
Mitt Romney (R)
Fred Thompson (R)
Other
  
Free polls from Pollhost.com

Updates: We are a famous physics blog!

And Ron Paul supporters have perfected a special brand of annoying.

And polls on the internet are useless.

None of which really qualifies as startling new information, I guess.

Cosmic Variance Goodies

by Julianne Dalcanton

In our on-going quest to satisfy the demands of our readership, we introduce the launch of http://cosmicvariance.spreadshirt.com, where you can find clothes and accessories imprinted with the soon-to-be-immortal words of Mark Trodden:

“Once you have tenure, it’s all edible panties, firearms, and blow.”

Shirts with the CV logo are also available. (Note that the graphic we have for the logo is on the small size. If you order one, and it looks like crap, let us know and we’ll discontinue the logo shirts until we make a bigger version.) Any profit will be quickly reinvested in some combination of edible panties, firearms, blow, and paying our web hosting overlords.

Facing the Future

by Sean Carroll

We now have a Facebook group for Cosmic Variance! But let me work up to it.

I had heard about Facebook many times, but had effortlessly resisted the temptation to learn anything about it or get involved in any way. It’s a social-networking site, allowing people to keep each other up to date with stuff they are doing. A pastime in which I pretty much have no interest, despite what one might gather from the fact that I have a blog and all that. While I’ll tell stories about travel or amusing anecdotes for purposes of local color, and mention the occasional big event, for the most part I prefer to use the blog to talk about ideas and keep the fascinating details of my everyday life a tightly-shrouded mystery.

But at some point, the “everyone is doing it, how hard can it be, and maybe it could even be fun” argument kicks in, and in a moment of weakness you sign up. I blame Carl Zimmer, who just joined himself, with the usual disclaimers. It’s free, and easy as pie — you sign up, post a photo if you like, and that’s it.

The basic point of Facebook, according to my limited understanding, is to have “Friends.” That is, a set of other Facebookers with whom you have (mutually) agreed to allow access to your profile and information. There is a quite brilliant application via which, if you choose to allow it, Facebook can zip through a conventional email program (Gmail, apple, etc) looking for email addresses of other people with Facebook accounts, and let you ask them to be friends. And then there are networks of common interest and all that stuff. The obvious use is that you can simply tell Facebook when you’ve decided to quit your job and hike across the Andes, rather than emailing all of your friends individually.

But there is a deep problem of postmodern community ethics here — who is a “Friend,” in the official Facebook sense? One group would be, you know, your actual friends. Another would be people with whom you have some less tangible, but nevertheless pretty mutual and well-defined, relationship — maybe you’ve exchanged emails, or comments on each others blogs. It’s all up to you where to draw the line.

But personally, I wouldn’t count someone as a “Friend” if I had simply read their book, or visited their blog, or listened to their radio show, without them knowing me at all. And vice-versa. I mean, I think — to be honest, I’m new at this, and have no idea what the standards are. It might be very natural, for example, for regular CV readers to want to be my friend, but I’m not really sure it fits my notion of what friendship is really all about.

Then I noticed that Crooked Timber has its own Facebook group. Which seemed, at first, like the dumbest thing in the world — why do you need some proprietary social network when you already have the damn blog?

Upon digging deeper, however, I realized it was actually the smartest thing in the world. (A very fine line.) With the Facebook group, people can come together and share pictures, or relevant stories or rants, without being “friends” and dealing with constant updates about what they all had for dinner last night. (Although advancing to friendship — or more! — is always possible.) And in fact there are lots of blogs that have their own Facebook group.

So, now, so do we. Go ahead and join up. Upload your photo (or not). Share videos and pictures from the regular “Fans of CV” get-togethers which I’m sure happen all the time. The Pharyngula group has over a hundred members — you don’t want to be shown up by a bunch of godless cephalophiles, do you?

But there’s no way I’m ever having a MySpace page.

Update: Seems to be working! Over a hundred members, and the irrepressible Mark Jackson has even started a conversation about physics-related movie titles.

Wikipedians to Action

by Sean Carroll

Did you know that there is a new Wikipedia entry for ScienceBlogs? And that there is even an entire category for blogs about science?

And yet there is no entry for Cosmic Variance. Just an unobtrusive little mention at the bottom of the entry on the actual concept of cosmic variance (not the blog).

Hint hint.

Summer Vacation

by Sean Carroll

Shakedown problems from our change of hosting services continue to pester us just a bit, but I think we’re getting the hang of it. We had to upgrade to a more powerful plan, which changed our monthly cost from “trivial” to “somewhat annoying,” so we’ve added some hopefully-unobtrusive Google ads to the sidebar. If you take our estimated earnings from the ads, subtract from that the piece demanded by the heavy hand of the state in the form of those collectivist utopians at the IRS, and subtract from what’s left the cost of our web host, you are left with a very good approximation of zero. Freewheeling public-intellectual leisure-time blogging is not the road to riches I was led to expect. (This despite the impression that I am only in it for the money.)

The “latest comments” plugin and the “comment preview” plugin both seem to have recently decided to act up, for reasons that may or may not have anything to do with anything else. They are temporarily disabled, but hopefully will see a comeback at some point.

Since things are largely in working order, however, this is as good a time as any for me to take my quasi-annual Summer Blogging Vacation. Not a real vacation, of course; precisely the opposite. There are a handful of good ideas languishing on my laptop, which need coaxing and encouragement in order to grow into refereed papers in respectable physics journals, and I’m going to concentrate on that for a while. I have all sorts of things I want to blog about, but for the most part it would take time to do a good job, and it’s time I don’t have right now. So I’m going to disappear for a few weeks, leaving you in the capable hands of the rest of the crew.

But I should go without offering congratulations to members of the Supernova Cosmology Project and the High-Redshift Supernova Team, who have just been awarded the Gruber Prize in Cosmology for discovering the acceleration of the universe. This wasn’t their first prize, and it won’t be their last. Our universe is big, it’s getting bigger, and it’s getting bigger faster — Edwin Hubble discovered the first two of these facts, and these two teams discovered the third. Not too shabby. For some inside scoop you should refer to the blogging member of the SCP, Rob Knop, who is also celebrating a new job. A distinguished astronomer forwarded to me the following sites, ready and available for follow-up reading:

http://www.theaustralian.news.com.au/story/0,25197,22092372-12332,00.html

And of course I can’t resist:

“Cosmology is the most scientifically rigorous, aesthetically elegant, and the most poetic of the sciences.”
Peter Gruber, Chairman of the Board
The Peter and Patricia Gruber Foundation

Hey, I’m just quoting here.

For Science!

Patience

by Sean Carroll

Still in the process of changing hosts, and as you may have noticed, there is still a bug or two. Hang in there.

Update: Most things are now working! We have said goodbye to Bluehost, and are now in the apparently-capable hands of InMotion Hosting. Hopefully we’ll be seeing less of the dreaded “CPU Exceeded” errors from now on. There are definitely still a few bugs in the system, but we’re hoping to swat them away before too long.

Various comments left while the transition was in progress have disappeared (as predicted), although some have been restored. Some that were not restored were of the alternative-science persuasion. I think that from now on we’re going to be considerably more Draconian about deleting such comments without warning, trying to nurture a safe haven for dull old mainstream scientific orthodoxy here. It’s a big Internet, though.

Downtime

by Sean Carroll

Yeah, we know, you can’t read the blog. We are once again the victim of frequent “This Account Has Exceeded Its CPU Quota” errors. Apparently we have a bunch of slow mysql queries, and need to optimize our indices. Which might be very straightforward, if any of us knew what those words meant. Dammit, Jim, I’m a doctor, not a database manager!

Here is the kind of error message we’re getting:

# Sat Jun 9 01:23:22 2007
# Query_time: 4 Lock_time: 0 Rows_sent: 27359 Rows_examined: 83792
SELECT
comment_post_ID, post_title
FROM (wp_comments LEFT JOIN wp_posts ON (comment_post_ID = ID))
WHERE comment_approved = ’1′
AND comment_type NOT LIKE ‘%pingback%’ AND comment_type NOT LIKE ‘%trackback%’
ORDER BY comment_date DESC

Full of important information, I’m sure, but I have no idea what it means or how to fix it. We might just change web hosts as a way to sidestep the problem, but that sounds like work. Any other suggestions?

Update: The particular problem mentioned here has been traced to a particular plugin and fixed. We’ve eliminated all of the noticeably slow mysql queries, but the problem persists. Once in a while an apparently ordinary request (“GET” a certain page, for example) takes 30 seconds, for no discernible reason. We’ve optimized the database, and even created some new indices, although I’m not even sure if that helps or hurts things. Maybe it will fix itself.

Pardon Our Dust

by Sean Carroll

(Update: the spam filter does seem to be picky, so please do let us know if your comments don’t come through. Unless you’re a spammer, I mean.)

We were temporarily down, after apparently being hacked into. Currently trying to upgrade to fix things. Patience!

Helping

We’ve finally upgraded to the latest version of WordPress. This should mean, among other things, that we can retrieve comments that were mistakenly deleted by an overzealous spam filter. Let us know if anything seems to not work.
