The Daily WTF: Curious Perversions in Information Technology

We Want Your Holiday Horrors

by Remy Porter in Announcements on 2025-11-26

As we enter into the latter portion of the year, folks are traveling to visit family, logging off of work in hopes that everything can look after itself for a month, and somewhere, someone, is going to make the choice "yes, I can push to prod on Christmas Eve, and it'll totally work out for me!"

Over the next few weeks, I'm hoping to get a chance to get some holiday support horrors up on the site, in keeping with the season. Whether it's the absurd challenges of providing family tech support, the last minute pushes to production, the five alarm fires caused by a pointy-haired-bosses's incompetence, we want your tales of holiday IT woe.

Copied Homework

by Remy Porter in CodeSOD on 2025-11-24

Part of the "fun" of JavaScript is dealing with code which comes from before sensible features existed. For example, if you wanted to clone an object in JavaScript, circa 2013, that was a wheel you needed to invent for yourself, as this StackOverflow thread highlights.

There are now better options, and you'd think that people would use them. However, the only thing more "fun" than dealing with code that hasn't caught up with the times is dealing with developers who haven't, and still insist on writing their own versions of standard methods.

Invalid Route and Invalid Route

by Remy Porter in CodeSOD on 2025-11-20

Someone wanted to make sure that invalid routes logged an error in their Go web application. Artem found this when looking at production code.

if (requestUriPath != "/config:system") &&
    (requestUriPath != "/config:system/ntp") &&
    (requestUriPath != "/config:system/ntp/servers") &&
    (requestUriPath != "/config:system/ntp/servers/server") &&
    (requestUriPath != "/config:system/ntp/servers/server/config") &&
    (requestUriPath != "/config:system/ntp/servers/server/config/address") &&
    (requestUriPath != "/config:system/ntp/servers/server/config/key-id") &&

    return nil
}

Are You Mocking Me?

by Remy Porter in CodeSOD on 2025-11-19

Today's representative line comes from Capybara James (most recently previously). It's representative, not just of the code base, but of Goodhart's Law: when a measure becomes a target, it ceases to be a good measure. Or, "you get what you measure".

If, for example, you decide that code coverage metrics are how you're going to judge developers, then your developers are going to ensure that the code coverage looks great. If you measure code coverage, then you will get code coverage- and nothing else.

Using an ADE: Ancient Development Environment

by Remy Porter in Feature Articles on 2025-11-18

One of the things that makes legacy code legacy is that code, over time, rots. Some of that rot comes from the gradual accumulation of fixes, hacks, and kruft. But much of the rot also comes from the tooling going unsupported or entirely out of support.

For example, many years ago, I worked in a Visual Basic 6 shop. The VB6 IDE went out of support in April, 2008, but we continued to use it well into the next decade. This made it challenging to support the existing software, as the IDE frequently broke in response to OS updates. Even when we started running it inside of a VM running an antique version of Windows 2000, we kept running into endless issues getting projects to compile and build.

In the Zone

by Remy Porter in Representative Line on 2025-11-17

Robert R picked up a bug in his company's event scheduling app. Sometimes, events were getting reported a day off from when they actually were.

It didn't take too long to find the culprit, and as is so often the case, the culprit was handling dates with strings.

Lucky Thirteen

by Remy Porter in CodeSOD on 2025-11-13

Wolferitza sends us a large chunk of a C# class. We'll take it in chunks because there's a lot here, but let's start with the obvious problem:

    private int iID0;
    private int iID1;
    private int iID2;
    private int iID3;
    private int iID4;
    private int iID5;
    private int iID6;
    private int iID7;
    private int iID8;
    private int iID9;
    private int iID10;
    private int iID11;
    private int iID12;
    private int iID13;
