Illustrated HTTP Error Codes

Via Boingboing, I found these awesome Illustrated HTTP Error Codes.

HTTP error codes are inherently funny to me, because of the all the possible double entendre possibilities involved. I mean, there’s 411: Length Required, 402: Payment Required (!), 414: Requested URL Too Long… The crude joke potential is just too high! In fact, Thinkgeek has a line of HTTPanties that exploits this very fact.

But these illustrations don’t pander to the lowest common denominator. Some of them are funny, like the dog that’s too big for his house (Requested Entity too large). Others are just kinda dumb. But the fact that someone drew these means there’s a bigger nerd out there than I. And I, for one, salute Ape Lad.

Introducing Notecentric: Facebook Edition!

So about a year ago I unveiled my killer web app, Notecentric. It was an online note taking app that I used in class. And I was about the only person who used it… Well, this Summer Facebook opened up their website to third party applications, and I immediately thought of Notecentric.

I haven’t really had much free time this Summer, though. I’ve been tele-working for a company during the day. But I found some time this weekend and last weekend to get a working version of Notecentric up on Facebook.

It really didn’t take much time since I had already done Notecentric once before. This was just sort of an adaptation, though Facebook has its own weird things to learn. Like redirects.

Anyway, check out and install the Notecentric app. Once I get 5 users, I can apply for Notecentric to be in the official directory! So hopefully that’ll be soon. I’m planning on adding more functionality as time permits, but for now, it’s totally working. I think.

XPath: Learn It!

So I’ve been trying to do some Facebook App stuff in Ruby on Rails (I already did some in PHP) and the RFacebook Gem uses this wacky XHTML/XML parser called “Hpricot.” The most experience I have with parsing XML is winging it with REXML until I got something that was somewhat correct.

So I tried using Hpricot tonight. Apparently it’s super fast, but the documentation assumes you know a whole lot about the mating habits (internal workings) of HTML and XML. And… I don’t really.

At least, not until I found this handy XPath tutorial! After actually reading the tutorial, rather than trying to wing/hack it again, I think I have a pretty good feel for this Hpricot thing. Basically, there’s a pretty simple vocabulary for describing the nested nature of XML. It’s impossible to figure out from the Hpricot tutorials (which I tried doing for a while), but insanely simple once you just look at the tutorial. Ah well, I guess that’ll teach me a lesson not to hack so much when it’s easier to RTFM…

Pownce Beta Impressions Update: Uploads Work!

Hmm. It looks like they fixed the uploads. Oh, Leah Culver, when will you learn that hotswaps aren’t infallible…

So now Pownce is actually kinda neat. One issue I saw was that one of the MP3s I uploaded (umm, totally a song I wrote and performed myself…) played at like, .01x speed. Weird. Also, I had registered as a “friend” of some people, then removed the friendship (or fanship) and their messages still stayed on my page for a while. Oh well.

Other than that, the site sure is slick. I can see this being a cool way to share neat music with people. It comes with its own mp3 player (which has some bugs), but so does gmail. I like the instant gratification feeling though. Aw hell, it’s fun to use, even if it isn’t a serious replacement for that thing I like to call “electronic mail.”

Pownce: Beta Impressions

I got a Pownce invite today (Thanks Jessica!) and finally got a chance to try out the hot beta. Unfortunately I couldn’t actually get any of my uploads to work…

While the site is pretty nice looking and slick, if the functionality doesn’t work, it’s useless. I think it could actually be somewhat useful for sharing files with a select group of friends. Like “hey, I like this song, check it out” and bam!

Then again, you could do that by email, but email is SOOOOO 1999! Actually, email’s more like 1979, but you get the idea. If only Pownce worked… The worst part is that it’s a beta product, but there’s no way to report a bug besides using (wait for it…) email. How ironic, indeed.
