A Black Hole At The Center Of The Galaxy

The Smile “The Slip” It’s unfortunate that The Smile records have to carry the weight of questions like “wait, is there never going to be another Radiohead album?” and “hold on, so is this basically Radiohead from now on?” But what can you do? Those are big questions for anyone who’d want to listen to […]

The Galaxy’s Greatest Detective

Vader really is the galaxy's greatest detective because he kills anyone who doesn't give him the answers he wants. Just watching him walk up to you, pipe in face mask, fire in his eyes, intimidates you into giving away who the murderer on Cherry St. is. Also, his Force sensitivity is greater than anyone else's. He can just sense if the killer is hiding in the cupboard under the staircase. He doesn't even have to look. He'll hold his lightsaber up to the door and activate it, making it thrust through the guy. This is the kind of shirt you wanna wear around your torso if you're in the middle of writing a genre-bending fan fiction. $7-21 | URL | Paypal Credit | S - 3XL ')}

Error'd: Relatively Speaking

Amateur physicist B.J. is going on vacation, but he likes to plan things right down to the zeptosecond. "Assume the flight accelerates at a constant speed for the first half of the flight, and decelerates at the same rate for the second half. 1) What speed does the plane need to reach to have that level of time dilation? 2) What is the distance between the airports?"

 

Contrarily, Eddie R. was tired of vacation so got a new job, but right away he's having second thoughts. "Doing my onboarding, but they seem to have trouble with the idea of optional."

 

"Forget UTF-8! Have you heard about the new, hot encoding standard for 2024?!" exclaimed Daniel , kvetching "Well, if you haven't then Gravity Forms co. is going to change your mind: URLEncode everything now! Specially if you need to display some diacritics on your website. Throw away the old, forgotten UTF-8. Be a cool guy, just use that urlencode!"

 

Immediately afterward, Daniel also sent us another good example, this time from Hetzner. He complains "Hetzner says the value is invalid. Of course they won't say what is or isn't allowed. It wasn't the slash character, it was... a character with diacritics! Hetzner is clearly using US-ASCII created in 1960's."

 

Finally this week, we pulled something out of the archive from Boule de Berlin who wrote "Telekom, the biggest German ISP, shows email address validation is hard. They use a regex that limits the TLD part of an email address to 4 chars." Old but timeless.

CodeSOD: Pay for this Later

Ross needed to write software to integrate with a credit card payment gateway. The one his company chose was relatively small, and only served a handful of countries- but it covered the markets they cared about and the transaction fees were cheap. They used XML for data interchange, and while they had no published schema document, they did have some handy-dandy sample code which let you parse their XML messages.

$response = curl_exec($ch);
$authecode = fetch_data($response, '<authCode>', '</authCode>');
$responsecode = fetch_data($response, '<responsecode>', '</responsecode>');
$retrunamount = fetch_data($response, '<returnamount>', '</returnamount>');
$trxnnumber = fetch_data($response, '<trxnnumber>', '</trxnnumber>');
$trxnstatus = fetch_data($response, '<trxnstatus>', '</trxnstatus>');
$trxnresponsemessage = fetch_data($response, '<trxnresponsemessage>', '</trxnresponsemessage>');

Well, this looks… worrying. At first glance, I wonder if we're going to have to kneel before Z̸̭͖͔͂̀ā̸̡͖͕͊l̴̜͕͋͌̕g̸͉̳͂͊ȯ̷͙͂̐. What exactly does fetch_data actually do?

function fetch_data($string, $start_tag, $end_tag)
{

  $position = stripos($string, $start_tag);
  $str = substr($string, $position);
  $str_second = substr($str, strlen($start_tag));
  $second_positon = stripos($str_second, $end_tag);
  $str_third = substr($str_second, 0, $second_positon);
  $fetch_data = trim($str_third);
  return $fetch_data;
}

Phew, no regular expressions, just… lots of substrings. This parses the XML document with no sense of the document's structure- it literally just searches for specific tags, grabs whatever is between them, and calls it done. Nested tags? Attributes? Self-closing tags? Forget about it. Since it doesn't enforce that your open and closing tags match, it also lets you grab arbitrary (and invalid) document fragments- fetch_data($response, "<fooTag>", "<barTag>"), for example.

And it's not like this needs to be implemented from scratch- PHP has built-in XML parsing classes. We could argue that by limiting ourselves to a subset of XML (which I can only hope this document does) and doing basic string parsing, we've built a much simpler approach, but I suspect that after doing a big pile of linear searches through the document, we're not really going to see any performance benefits from this version- and maintenance is going to be a nightmare, as it's so fragile and won't work for many very valid XML documents.

It's always amazing when TRWTF is neither PHP nor XML but… whatever this is.

Celebrate Caturday in Style with 26 Moments from the Magical Life of Panko the Chonky Cat Child and All Her Hilarious Feline Friends

Spending Cautrday with a cat, let alone a clouder of cats is a truly special experience. There is almost a slight sense of religion to it in how regimented and celebratory the day is. There are specific feeding times for different kinds of treats, each one representing a different feline quality that we love and cherish. There are specific zoomie times that must be observed and much to our dismay there are the clawminal times that must be observed and not interfered with. So if you are spending your Caturday with cats, or simply want to see what it would be like we made this list to help you celebrate Caturday in style with marvelous moments from the magical life of Panko the chonky cat and all her hilarious feline friends.

From the cute kitten whose favorite part of Caturday is the fish smoothie feeding, to the clawminal catto who is all about the chaos of Caturday, to the flabbergasted feline who cannot believe that treat time is over and that he missed it due to indulging in too many zoomies.
