The Daily WTF: Curious Perversions in Information Technology

How Many Quarters to a Dollar?

by Remy Porter in CodeSOD on 2019-04-30

Myrtis joined Initech as their first on-staff software developer. Up to that point, Initech outsourced all the software development on their payroll/billing system. The contractor kept raising their rates, Initech’s business needs kept growing, and eventually they decided it was time to hire an in-house developer.

Which meant Myrtis got to inherit all of that outsourced development. All that code, all of which had some pretty significant financial implications if it contained any bugs or errors, all developed by a third-party to a third-party.

Log Every Error

by Remy Porter in Representative Line on 2019-04-25

Tom C inherited some Go from another developer, and writes, “I’m pretty sick of finding this sort of stuff in this code.”

	if log, err = dockerservice.GetLoggerInstance(); err != nil {
		log.Err(fmt.Sprintf("Logger error: %v \n", err))
  }

A Linking Approach

by Remy Porter in CodeSOD on 2019-04-24

Web development has gone in a bizarre circle since the early 2000s. Whet ASP.NET launched, its “big sell” was Web Forms, which allowed developers to use a desktop model for handling interactive applications. The basic logic you used for building a desktop forms application would work for a web app, because at the time, everyone was a desktop developer.

Fast forward to today, where we bundle our applications up in web browsers and use web metaphors to build desktop applications, because everyone’s a web developer. This may be proof that developers can only ever learn a single way of doing things, and that two options is one too many.

Be True to Yourself

by Remy Porter in CodeSOD on 2019-04-22

Ben M recently inherited some code from some Highly Paid Consultants. These consultants needed to be able to set some flags to control the behavior of the application, and for whatever reason, these flags needed to be strings. It probably wasn't a good reason, but there was some reason. The consultants wrote the module which set the flags, and guaranteed that the flags were only ever "true" or "false".

To parse those flags back into boolean values, they did it the true Highly Paid Consultant way: they used a generic "string to boolean" solution they copied from Stack Overflow instead of Boolean.Parse, the built-in C# method for turning "true" into a boolean value.

Waaaaaiiiiit for it…

by Remy Porter in CodeSOD on 2019-04-18

There are many moments where our multi-threaded code needs to gurantee only one code path is executing at a time. That’s why we have locks, semaphores, mutexes, and so on. But those are all pretty complicated. Vincent H recently was reviewing someone’s code, and they found a far more elegant solution, which simply uses booleans.

For example, you could whip up a wait loop with a simple block like this:

Tern Your View

by Remy Porter in Representative Line on 2019-04-16

We all just love ternaries around here. So much. A powerful form of code golf, they can clarify and they can confound, but usually it’s just confounding.

Christopher sends us this example, saying, “This is an accurate indicator of the rest of the code.”

Typing for Types

by Remy Porter in CodeSOD on 2019-04-15

Today, any sort of data access layer we build is going to be rooted in some sort of object-oriented design. It might be a full ORM, it might be an object-store database, it might be one of any number of kinds of database mapping tool.

What we usually don't do anymore is get a resultset with no type information, where we have to invoke the proper "GetXXX" method to fetch data out of what behaves more-or-less like a dictionary. Oh, we might have to do this, but we'll almost always bury it under a layer of abstraction to hide the ugly details.

Oooooooooooooo no

by Remy Porter in CodeSOD on 2019-04-11

Kids these days have their flexboxes and their ems and their position absolutes. In the olden days of HTML, we arranged everything with table tags and we liked it. Well, some of us did. Mike was recently doing part of a redesign, and when the background color of the page was changed, a bunch of garbage text appeared in various input forms. How could changing the CSS background color cause garbage text to appear?

<b>Billing Address Information</b>
<p class="style3">Billing Address 1:<font color=white>0ooo0.....</font><input type="text" name="BillStreet1"></p>
<p class="style3">Billing Address 2:<font color=white>o00000...</font><input type="text" name="BillStreet2"></p>
<p class="style3">Billing City:<font color=white>00o00..0.o...0..</font><input type="text" name="BillCity"></p>

It Just Won't Stop

by Remy Porter in CodeSOD on 2019-04-10

Kara's ongoing quest to tame her codebase continues. First it was serialization, then more strings, then some serial communication.

Today, it's threads.

Count Me Out

by Remy Porter in CodeSOD on 2019-04-09

“My program needs to send some emails,” the developer thought to themselves. The then thought about how this could go wrong, probably thinking that, boy, they’ve got an external server, and boy, spam is a problem, and that server might get upset if you’re sending too many messages at once, or too quickly. That’s a thing which could happen, right?

That’s at least a plausible line of thought for the code Juana found, which looks something like this:

Zoning Out

by Remy Porter in CodeSOD on 2019-04-08

Matthew D was recently helping a friend plan a trip to Europe from the US. After shopping around a bit, they found a rather affordable airline based out of Poland that fit both their budget and their destination, and started booking a flight.

It was going well until it came time for them to enter their passport information. The site complained that the expiry date was invalid. Since that complaint was happening without a page reload, Matthew was pretty sure it was a buggy bit of client-side validation, so he pulled up the dev tools and poked around.

Going the Distwince

by Remy Porter in CodeSOD on 2019-04-04

Stored procedures are a bit of a WTF breeding ground. Your average stored procedure language is more limited than your average general purpose language, the syntax is usually clunkier, and everything is so data-focused that implementing logic beyond simplistic processes can be more challenging than one would expect.

Of course, this gets harder if you don’t bother to learn how to do string concatenation. Darrin found an example of that while debugging a store procedure:

The Myth of Datyphus

by Remy Porter in CodeSOD on 2019-04-03

PHP gets a lot of flack, but perhaps we're taking the wrong perspective on things. Perhaps the gods have condemned PHP to ceaselessly rolling CMSes and wikis up the hill, whence they roll back down under their own weight. The gods had thought, with some reason, that there is no more dreadful punishment than futile and hopeless labor.

I mean, look at this code:

An Objectionable Dictionary

by Remy Porter in CodeSOD on 2019-04-02

You may remember Karl from a few months back. Karl's organization is notorious for crunch, and it results in some awful sins when you're trying to cram 50 hours of work into the last five hours before launch.

Karl didn't write this particular bit, but dreads the day when he has to look at it or change what it does.
