I had no luck viewing the Transit of Venus. I didn’t have time to find and meet up with any sort of viewing party that might have a telescope or other equipment, and I’m kicking myself for not having tracked down a set of eclipse glasses of my own, so I was left with a handheld pinhole “camera” made out of a cardboard gum package. The clearest image I could get with that was about 1/4″, too small to see the tiny speck moving across the sun. (Though I could see the cloud bank the sun was setting into about the point that I gave up and went inside.)

Oh, well. I can’t be too upset, since I got to see a great solar eclipse two weeks ago. And there are plenty of places to watch online and find pictures.

I had several plans for viewing today’s solar eclipse, depending on the weather. As the hour approached and clouds loomed in the west, I decided that my best bet would be to get above the cloud cover, and drove up into the hills to Del Cerro Park at the top of the Palos Verdes peninsula.

I’m glad I did, because a lot of other people had the same idea.

Individuals, couples, families, groups of friends, groups from schools — and everyone had a different way to see the eclipse: pinhole cameras, binoculars projecting on cardboard, welding helmets, “eclipse glasses” and more. There were also people who were just out for a day at the park, and wanted to know what was going on.

If J had been a few years older it would have been a family event for us too, but at a year and a half, I don’t think I would have been able to explain anything beyond “don’t look at the sun.” A partial eclipse is easy to miss if you’re not paying attention.

I’d cobbled together a pinhole camera the day before from two Amazon boxes, a sheet of paper, a sheet of aluminum foil, and lots and lots of packing tape. I actually started with just one box and I decided the image wasn’t big enough, so I grafted on a second. Even then it was only about 3/8″ across, but when testing it I could see the edges of clouds drifting across the sun, so I figured it would work. It did. Continue reading →

The classic link-sharing site Delicious is still around, trying to find a niche in the new social media world. One of the things they’ve recently done is set up a way to import all links you post on Twitter. It does a historical import when you link the account, and then pulls in new tweets going forward.

It’s a cool idea, depending on how you use the sites, and they’ve made it just flexible enough that anyone who might want to do this in the first place will find a way to match their use case.

In my case, I mainly used Delicious as an additional bookmark store that I could access across browsers and accounts, though for the most part that’s been replaced by Xmarks. I haven’t used it as much for deliberate sharing, though I’ve posted the occasional link in the hopes that someone might notice it.

Anyway, I linked it up with my personal Twitter account, left the site for a few hours, then came back to see just how far back it had imported. It went back about 3 years, pulling in over 1,000 links that I’d posted to Twitter.

The Good:

  • It merges duplicates.
  • Links are backdated to the day you posted the tweet.
  • All imported links are tagged with “from twitter” (you can change this), making it easy to filter.
  • Hashtags are imported as tags.
  • The text of your tweet becomes the comment.
  • It extracts titles and thumbnail images from the links.
  • It can follow some redirectors, including Twitter’s own t.co.

The Bad:

  • It doesn’t follow all redirectors. There are an awful lot of bit.ly and is.gd links in there.
  • That also means that if I tweeted the same link twice using different link shorteners, it doesn’t resolve the duplicates.
  • A lot of those links were only of short term interest.
  • Three years is plenty of time for a redirector (or, of course, a target link) to shut down. Fortunately, it looks like I didn’t use tr.im much.
  • My blog automatically tweets links to new posts, which means every post I’ve made in the last three years is in there – the earliest with an is.gd or tinyurl link, the later ones with bit.ly. I don’t need those in my own bookmarks (with a few exceptions), and as far as sharing goes, it makes me feel spammy to plug three years’ worth of backlist at once.
  • Searching for links gives you less-functional results than simply looking at your list or filtering by tag. Not all details appear on the results page, bulk actions aren’t available, and you can’t always delete a link if you edit it from search results. This meant I couldn’t, for instance, search for “New post” or “K-Squared Ramblings,” skim the titles and bulk-delete the bookmarks to my own content.

Over the last couple of weeks I’ve been taking a few minutes here and there to go through what started as 60 pages’ worth of imported links, delete the ones I don’t want to keep and fix up the ones I do. It started out faster than my last Twitter-related cleanup project, but that’s because there were a lot of auto-posted links I could just delete without taking the time to evaluate or label them. It’s already slowing down.

I could just leave all the clutter there, but part of the point is for this to be my bookmarks-away-from-home, and it’s easier to find stuff without the extra junk.

On the plus side, between this and the broken link cleanup, I’m getting to see a bunch of old posts and photos I’d forgotten about. That’s been an interesting process.

It’s also convinced me that linkblogging round-ups really don’t belong on this blog. I still do them on Speed Force, but that’s in part because Speed Force has readers who don’t follow the social networks. (OK, let’s be honest: because Speed Force has readers.) Here, where it’s just a personal site, I’m better off sticking with the best medium for each post. That means Twitter, Facebook and Google+ for short posts (barring a few categories that I’ve got history here, like license plate spotting), the blog for longer posts, and social networks for link sharing.

Last week, the webcomic XKCD ran a strip, Umwelt. Or perhaps it would be better to describe it as several comic strips.

As explained in the mouseover text, the title refers to the idea that because animals have different senses, each animal effectively inhabits a different reality. This can philosophically be extended to human perceptions.

Keeping that in mind, make sure you read it in a few different web browsers (both desktop and mobile!) for the full effect (JavaScript required). And try resizing the window.

As an art project, it’s the best use of browser-sniffing I’ve ever seen.

I turned on the broken link checker plugin at lunchtime, and let it run through the site over the next few hours* before checking back this evening.

Holy crap, there’s a lot of outdated links on this site! Over 300, in fact, linking to things like…

  • News organizations that discard their archives, or hide them behind paywalls.
  • Businesses that have, well, gone out of business.
  • Blogs that have shut down or moved.
  • Personal sites that have been abandoned.
  • Sites that have reorganized without setting up redirect rules for their old link structure. (Even the Star Wars official site did this with the movie pages!)

One of the dead links is, appropriately enough, to an article on top 10 web design mistakes. (I guess they missed one!) Another is actually on one of my articles on link rot from way back when.

And then there are the 700+ links that are being redirected, some of which should probably be updated, but some of which are certainly gateway pages — and some of which are probably pointing to a new site that took over the name, but not the content.

It’s often stated that once something goes up on the Internet, it’s there forever. But that’s not entirely true. What it is, is beyond your control. If someone else makes a copy, you can’t take it down (like the fable about releasing a bag of feathers from a mountain top, and then trying to collect all the feathers). But any individual copy — even the original — exists at the whim of whoever owns or maintains that site.

One question remains: Do these dead links matter?

I think they do, for three reasons:

  1. Links are source trails. A valid link may support what you’re saying, indicating that you know what you’re talking about. (Think of all those [citation needed] notes on Wikipedia.)
  2. Related to that, links provide context. Even today, with the masses chattering in short form on Facebook and Twitter, you’ll find people writing articles and responding to them with other articles. As long as the links remain intact, these aren’t monologues — they’re a conversation.
  3. When a whole site goes offline, you never know who’s going to pick it up. It could be someone with an opposite political agenda. It could be a spammer or malware peddler. A commenter from 5 years ago might lose their site and have it taken over by someone selling knockoffs of little blue pills — and now guess what you’re linking to?

*Something about the plugin really taxes the VPS that DreamHost offers, which is why I don’t have it running all the time anymore, but it only seems to affect the blog it’s running in, and of course it doesn’t impact static pages.

It’s true. I’ve been staring at two large glowing rectangles for 8 hours now, taking occasional breaks to stare at a smaller glowing rectangle (as I did on my lunch break), and will probably spend some time staring at one of several glowing rectangles during my evening at home.

It really sounds pathetic when you put it that way.
