The Daily WTF: Curious Perversions in Information Technology

Turning Thirty

by Remy Porter in Feature Articles on 2026-04-21

Eric O worked for a medical device company. The medical device industry moves slowly, relative to other technical industries. Medical science and safety have their own cadence, and at a certain point, iterating faster doesn't matter much.

Eric was working on a new feature on a system that had been in use for thirteen years. This new feature interacted with a database which stored information about racks of test tubes, and Eric's tests meant creating several entries for racks of test tubes. And that's when Eric discovered that the database only allowed thirty racks. Add any more, it would just roll right back over to one.

Good Etiquette

by Remy Porter in CodeSOD on 2026-04-20

"Here, you're a programmer, take this over. It's business critical."

That's what Felicity's boss told her when he pointed her to a network drive containing an Excel spreadsheet. The Excel spreadsheet contained a pile of macros. The person who wrote it had left, and nobody knew how to make it work, but the macros in question were absolutely business vital.

We'll Hire Better Contractors Next Time, We Promise

Nona writes: "this is the beginning of a 2100 line function."

That's bad. Nona didn't send us the entire JavaScript function, but sent us just the three early lines, which definitely raise concerns:

Three Letter Acronyms, Four Letter Words

Candice (previously) has another WTF to share for us.

We're going to start by just looking at one fragment of a class defined in this C++ code: TLAflaList.

A Hole in Your Plan

by Remy Porter in Feature Articles on 2026-04-14

Theresa works for a company that handles a fair bit of personally identifiable information that can be tied to health care data, so for them, security matters. They need to comply with security practices laid out by a variety of standards bodies and be able to demonstrate that compliance.

There's a dirty secret about standards compliance, though. Most of these standards are trying to avoid being overly technically prescriptive. So frequently, they may have something like, "a process must exist for securely destroying storage devices before they are disposed of." Maybe it will include some examples of what you could do to meet this standard, but the important thing is that you have to have a process. This means that if you whip up a Word document called "Secure Data Destruction Process" and tell people they should follow it, you can check off that box on your compliance. Sometimes, you need to validate the process; sometimes you need to have other processes which ensure this process is being followed. What you need to do and to what complexity depends on the compliance structure you're beholden to. Some of them are surprisingly flexible, which is a polite way of saying "mostly meaningless".

Non-cogito Ergo c_str

by Remy Porter in CodeSOD on 2026-04-13

Tim (previously) supports a relatively ancient C++ application. And that creates some interesting conundrums, as the way you wrote C++ in 2003 is not the way you would write it even a few years later. The standard matured quickly.

Way back in 2003, it was still common to use C-style strings, instead of the C++ std::string type. It seems silly, but people had Strong Opinions™ about using standard library types, and much of your C++ code was probably interacting with C libraries, so yeah, C-strings stuck around for a long time.

Take a Percentage

by Remy Porter in CodeSOD on 2026-04-09

When looking at the source of a major news site, today's anonymous submitter sends us this very, very mild, but also very funny WTF:

	<div class="g-vhs g-videotape g-cinemagraph" id="g-video-178_article_slug-640w"
		 data-type="videotape" data-asset="https://somesite.com/videos/file.mp4" data-cinemagraph="true" data-allow-multiple-players="true"
		 data-vhs-options='{"ratio":"560:320"}'
		 style="padding-bottom: 57.14285714285714%">

Two Conversions

by Remy Porter in CodeSOD on 2026-04-08

The father of the "billion dollar mistake" left us last month. His pointer is finally null. Speaking of null handling, Randy says he was "spelunking" through his codebase and found this pair of functions, which handles null.

public String getDataString() {
    if (dataString == null) {
        return Constants.NOT_AVAILABLE;
    }
    return asUnicode(dataString);
}
