Aggregation of Concatenation

by in Representative Line on

A few years back, JSON crossed the “really good hammer” threshold. It has a good balance of being human readable, relatively compact, and simple to parse. It thus has become the go-to format for everything. “KoHHeKT” inherited a service which generates some JSON from an in-memory tree structure. This is exactly the kind of situation where JSON shines, and it would be trivial to employ one of the many JSON serialization libraries available for C# to generate JSON on demand.

Orrrrr… you could use LINQ aggregations, string formatting and trims…

Return of the Mask

Sometimes, you learn something new, and you suddenly start seeing it show up anywhere. The Baader-Meinhof Phenomenon is the name for that. Sometimes, you see one kind of bad code, and the same kind of bad code starts showing up everywhere. Yesterday we saw a nasty attempt to use bitmasks in a loop.

Today, we have Michele’s contribution, of a strange way of interacting with bitmasks. The culprit behind this code was a previous PLC programmer, even if this code wasn’t running straight on the PLC.

A Bit Masked

The “for-case” or “loop-switch” anti-pattern creates some hard to maintain code. You know the drill: the first time through the loop, do one step, the next time through the loop, do a different step. It’s known as the “Anti-Duff’s Device”, which is a good contrast: Duff’s Device is a clever way to unroll a loop and turn it into a sequential process, while the “loop-switch” takes a sequential process and turns it into a loop.

Ashlea inherited an MFC application. It was worked on by a number of developers in Germany, some of which used English to name identifiers, some which used German, creating a new language called “Deunglish”. Or “Engleutch”? Whatever you call it, Ashlea has helpfully translated all the identifiers into English for us.

A Quick Replacement

Lucio Crusca was doing a bit of security auditing when he found this pile of code, and it is indeed a pile. It is PHP, which doesn’t automatically make it bad, but it makes use of a feature of PHP so bad that they’ve deprecated it in recent versions: the create_function method.

Before we even dig into this code, the create_function method takes a string, runs eval on it, and returns the name of the newly created anonymous function. Prior to PHP 5.3.0 this was their method of doing lambdas. And while the function is officially deprecated as of PHP 7.2.0… it’s not removed. You can still use it. And I’m sure a lot of code probably still does. Like this block…

There’s a phenomenon I think of as the “evolution of objects” and it impacts novice programmers. They start by having piles of variables named things like userName0, userName1, accountNum0, accountNum1, etc. This is awkward and cumbersome, and then they discover arrays. string* userNames, int[] accountNums. This is also awkward and cumbersome, and then they discover hash maps, and can do something like Map<string, string>* users. Most programmers go on to discover “wait, objects do that!”

Not so Brian’s co-worker, Dagny. Dagny wanted to write some C++, but didn’t want to learn that pesky STL or have to master templates. Dagny also considered themselves a “performance junkie”, so they didn’t want to bloat their codebase with peer-reviewed and optimized code, and instead decided to invent that wheel themselves.

The Same Date

Oh, dates. Oh, dates in Java. They’re a bit of a dangerous mess, at least prior to Java 8. That’s why Java 8 created its own date-time libraries, and why JodaTime was the gold standard in Java date handling for many years.

But it doesn’t really matter what date handling you do if you’re TRWTF. An Anonymous submitter passed along this method, which is meant to set the start and end date of a search range, based on a number of days:

Every programming language has a *bias* which informs their solutions. Object-oriented languages are biased towards objects, and all the things which follow on. Clojure is all about function application. Haskell is all about type algebra. Ruby is all about monkey-patching existing objects.

In any language, these things can be taken too far. Java's infamous Spring framework leaps to mind. Perl, being biased towards regular expressions, has earned its reputation as being "write only" thanks to regex abuse.
