Illustrations: What HTTP Errors Look Like

By Josh Catone

These are actually a couple of years old, so avid users of Flickr may have already seen them. I just came across them for the first time last night, however, via a link on Hacker News and found them very amusing, so I thought I’d share. They make a nice, light Friday post.

The following are illustrations from cartoonist Adam Koford (who seems to spend most of his time now writing a comic strip about a pair of hobo LOLcats). They’re rather ingenious illustrations of HTTP errors. I’ve included a few of most clever below, but there are more at the original Flickr set (16 to be precise).

Which are your favorites? I rather like “400 Bad Request” (pictured at right) and “405 Method Not Allowed” (not pictured). Adam, if you’re reading: please make these available as a set of prints or postcards!

408 Request Timeout

413 Requested Entity Too Large

415 Unsupported Media Type

Remember to see all 16 illustrations at the original Flickr set. Then come back here to let us know which are your favorites.

    Absolutely classic stuff, but where’s 412 Precondition Failed?

  • Is the hotdog the equivalent of the Meatball Sunday? 415 Gets my vote. Is that an ABBA record? Digital Underground, perhaps?

    Error is the difference between a measured value and the true value of a quantity or attribute. It is the factor that limits the precision and accuracy of the result of a measurement. Errors can be divided into two components such as random error and systematic error. Random error is always present in a measurement. It is caused by inherently unpredictable fluctuations in the readings of a measurement apparatus or in the experimenter’s interpretation of the instrumental reading. Systematic error is predictable, and typically constant or proportional to the true value. If the cause of the systematic error can be identified, then it can usually be eliminated. The total error, which results from the sum of the two components, is also referred to as uncertaint.
