The Daily WTF: Curious Perversions in Information Technology

Classic WTF: One-and-a-Half-Tiered Application Design

by Jake Vinson in CodeSOD on 2026-05-25

It's a holiday in the US today, so we're reaching back into the archives. What we really need is a single function that can do it all, and by "it" we mean "ruin your life." Original --Remy

There are several types of bad code; there's lazy code, frantic code, unaware-of-a-better-way code, and aware-of-a-better-way-but-too-apathetic-to-do-it code, to name a few. Then there're amalgamations of different types of bad code.

Môshe encountered such an amalgam when his company was trying out a new delivery service. Môshe spent some time evaluating the IE-only web interface, and was curious about some JavaScript errors he was getting. Strangely, he noticed variables named dateSQL, newSQLTag, and modeSQL.

Classic WTF: A Systematic Approach

by Jake Vinson in Best of… on 2024-09-02

It's a holiday in the US today, where we celebrate labor and laborers. Enjoy a story of working smarter, not harder, to meet unrealistic deadlines and create a lot more work for someone in the future. Original --Remy

It was the early 1990s and Frank was living the dream – unshaven, in pajama bottoms and his favorite hockey jersey, having just woken up at 12:18 PM, was now working in the dim light of his basement on one of his freelance projects. Just as he was sipping a cup of coffee, the phone rang.

Frank tried fruitlessly to fight an unexpected open-mouthed yawn when he picked up the receiver. "OOOOAAAaaahhhh... hello?"

Classic WTF: Scratch One Inevitability

by Jake Vinson in Feature Articles on 2022-04-18

Since this weekend was a holiday, and today is Tax Day in the US, we're reaching back into the archives for this classic that fits the theme. Original -- Remy

Before Curtis even got to sit down at his desk, he was accosted by a frenzied, sweating junior developer. "OhmygodCurtis," he began. Curtis extended his hand in a "calm the hell down" gesture and allowed him to continue. "A whole bunch of our stores had no data posted last night and I'm not sure why orwhat to doabout it or whoIshouldtalktoand-" Curtis gestured again, to which the developer handed him a thin stack of papers. After a deep breath, the developer continued. "It's a list of the stores that didn't post last night."

The stores in question were part of what we'll call Hewitt & Liberty Block – a reasonably large tax preparation company serving a handful of states with over 2,000 retail locations. Each of the locations was set up to post tax data and sales records to the central computer at the main facility. According to Curtis's list of stores that hadn't posted any data, it was nearly 1/4. It was going to be a long day.

Classic WTF: Security By Letterhead

by Jake Vinson in Feature Articles on 2018-09-03

It's a holiday in the US, so we're turning back the clock a bit.
How do you make sure nobody issues an unauthorized request for a domain transfer? This registrar has serious security to prevent just that kind of event. You know this must be a classic, because it involves fax machines. Original -- Remy

Security through obscurity is something we've all probably complained about. We've covered security by insanity and security by oblivity. And today, joining their ranks, we have security by letterhead.

John O'Rourke wrote in to tell us that as a part of his job, he often has to help clients transfer domain names. He's had to jump through all kinds of crazy hoops to transfer domain names in the past; including just about everything except literally jumping through hoops. After faxing in a transfer request and receiving a rejection fax an hour later, he knew he was in for a fight.

Classic WTF: Illicit Process Improvement

by Jake Vinson in Feature Articles on 2016-11-25

In celebration of Black Friday, also known as "Retail Hellscape", let's look at a retail-oriented classic WTF, which originally ran way back in 2007. We'll resume our regularly scheduled WTFs next week.--Remy

Christian R. was in trouble. Despite his experience across hardware and software, desktops and server clusters, thumb drives and SANs, he hadn't found any freelance work in weeks. It was clear that he'd have to figure something out to pay the bills.

In August, Christian applied at Drab's PCs, a large retail chain focused on computer hardware and software. He'd shopped there for years and had an impressive level of knowledge about their products, so he accepted a position in Technical Sales.

Classic WTF: Some Crazy Reason

by Jake Vinson in CodeSOD on 2016-05-30

It's Memorial Day in the US, which is a holiday remembering those who have died in wars, which we celebrate by not going to work and generally grilling something. I leave it to someone smarter than myself to unpack the deeper meaning there. What it means here at TDWTF is that we're digging back into the archives to treat you to a classic WTF. - Remy

One time, out of boredom, I wrote a little utility called BitVerifier. It would loop over a folder and check every bit of each file. If the bit's value wasn't one or zero, it would prompt the user for the correct bit. At least in theory. I somehow never encountered a file with a "two" bit. But I got one key component right – an understanding of the valid range of values.

Rob K.'s colleague didn't even get that far.

Classic WTF: XML Abuse

by Jake Vinson in CodeSOD on 2015-07-09

Is it still trendy to hate on XML? Of course it is! But this WTF would still be a WTF if it were built in JSON, because this is terrible.

This classic comes from 2008, but finding WTFs in XML knows no decade. - Remy

"Where I work we keep a lot of data stored in XML files," Ben writes. "They're not your average XML files, though — they're special." His colleague invented the following technique (recommended for senior level XML programmers only).
