The Daily WTF: Curious Perversions in Information Technology

The XML Dating Service

by Remy Porter in CodeSOD on 2025-07-09

One of the endless struggles in writing reusable API endpoints is creating useful schemas to describe them. Each new serialization format comes up with new ways to express your constraints, each with their own quirks and footguns and absolute trainwrecks.

Maarten has the "pleasure" of consuming an XML-based API, provided by a third party. It comes with an XML schema, for validation. Now, the XML Schema Language has a large number of validators built in. For example, if you want to restrict a field to being a date, you can mark it's type as xsd:date. This will enforce a YYYY-MM-DD format on the data.

Off Color

by Remy Porter in CodeSOD on 2025-07-08

Carolyn inherited a somewhat old project that had been initiated by a "rockstar" developer, and then passed to developer after developer over the years. They burned through rockstars faster than Spinal Tap goes through drummers. The result is gems like this:

private void init(){
	ResourceHelper rh = new ResourceHelper();
	for ( int i = 0; i < 12; i++) {
		months[i] = rh.getResource("calendar."+monthkeys[i]+".long");
		months_s[i] = rh.getResource("calendar."+monthkeys[i]+".short");
	}
	StaticData data = SomeService.current().getStaticData();
	this.bankHolidayList = data.getBankHolidayList();
	colors.put("#dddddd", "#dddddd");
	colors.put("#cccccc", "#cccccc");
	colors.put("#e6e6e6", "#e6e6e6");
	colors.put("#ff0000", "#ffcccc");
	colors.put("#ffff00", "#ffffcc");
	colors.put("#00ff00", "#ccffcc");
	colors.put("#5050ff", "#ccccff");
	colors.put("#aa0000", "#ff9999");
	colors.put("#ff8000", "#ffcc99");
	colors.put("#99ff99", "#ccffcc");
	colors.put("#ffcc99", "#ffffcc");
	colors.put("#ff9966", "#ffcc99");
	colors.put("#00c040", "#99cc99");
	colors.put("#aadddd", "#ccffff");
	colors.put("#e0e040", "#ffff99");
	colors.put("#6699ff", "#99ccff");
}

All Locked Up

by Remy Porter in CodeSOD on 2025-07-07

Dan was using a third-party database which provided a PHP API. At one point, Dan was running into an issue where he actually needed locks on the database. Fortunately for him, the vendor documentation told him that there was a method called obtainRowLock.

obtainRowLock($table, $where) - Attempt to lock a row, will escalate and lock the table if row locking is not supported, will escalate and lock the database if table locking is not supported; returns true on success, false on failure
$table - name of table to lock
$where - WHERE clause to define rows, ex: "WHERE id=52". If left empty, function will assume a table lock

The Last Last Name

by Remy Porter in CodeSOD on 2025-07-03

Sometimes, you see some code which is perfectly harmless, but illustrates an incredibly dangerous person behind them. The code isn't good, but it isn't bad in any meaningful way, but it was written by a cocaine addled Pomeranian behind the controls of a bulldozer: it's full of energy, doesn't know exactly what's going on, and at some point, it's going to hit something important.

Such is the code which Román sends us.

And Config

by Remy Porter in CodeSOD on 2025-07-02

It's not unusual to store format templates in your application configuration files. I'd argue it's probably a good and wise thing to do. But Phillip inherited a C# application from a developer who "abandoned" it, and there were some choices in there.

<appSettings>
        <add key="xxxurl" value="[http://{1}:7777/pls/xxx/p_pristjek?i_type=MK3000{0}i_ean={3}{0}i_style=http://{2}/Content/{0}i_red=http://{2}/start.aspx/]http://{1}:7777/pls/xxx/p_pristjek?i_type=MK3000{0}i_ean={3}{0}i_style=http://{2}/Content/{0}i_red=http://{2}/start.aspx"/>
</appSettings>

It's Not Wrong to Say We're Equal

by Remy Porter in CodeSOD on 2025-07-01

Aaron was debugging some C# code, and while this wasn't the source of the bug, it annoyed him enough to send it to us.

protected override int DoCompare(Item item1, Item item2)
{
	try
	{
		DateTime thisDate = ((DateField)item1.Fields["Create Date"]).DateTime;
		DateTime thatDate = ((DateField)item2.Fields["Create Date"]).DateTime;

		return thatDate.CompareTo(thisDate);
	}
	catch (Exception)
	{
		return 0; // Sorry, ran out of budget!
	}
}

A Highly Paid Field

by Remy Porter in CodeSOD on 2025-06-30

In ancient times, Rob's employer didn't have its own computer; it rented time on a mid-range computer and ran all its jobs using batch processing in COBOL. And in those ancient times, these stone tools were just fine.

But computing got more and more important, and the costs for renting time kept going up and up, so they eventually bought their own AS/400. And that meant someone needed to migrate all of their COBOL to RPG. And management knew what you do for those kinds of conversions: higher a Highly Paid Consultant.

Classic WTF: Take the Bus

by Remy Porter in Feature Articles on 2025-06-23

It's summer break time, here at TDWTF, and based on this classic, we shouldn't be traveling by bus. Original --Remy

Rachel started working as a web developer for the local bus company. The job made her feel young, since the buses, the IT infrastructure, and most of their back-office code was older than she was. The bus fare-boxes were cash only, and while you could buy a monthly pass, it was just a little cardboard slip that you showed the driver. Their accounting system ran on a mainframe, their garage management software was a 16-bit DOS application. Email ran on an Exchange 5.5 server.
