Serial Properties

by in CodeSOD on

Jan wrote some code that set a property, and a few lines later had to write code to read that value- and the compiler complained. Which is what drew his attention to this C# code:

public string ViewNodeFilter
{
        protected get
        {
                if (viewNodeFilter.IsNotValid())
                {
                        return "null";
                }
                return new JavaScriptSerializer().Serialize(viewNodeFilter);
        }
        set { viewNodeFilter = value; }
}

Adrian M. lit up this blooper for us. "Apparently Siemens Mobility wasn't satisfied that a mere 95-year copyright term would be enough for the brochure about their m60-series traffic light controller. I hope I won't have to wait until 2029 for a green light." See for yourself here.


False True is True False

Languages which do type-coercion are generally setting users up for failure. At some point, you'll make some assumption about your inputs, and then type-coercion kicks in and changes what you expect. We see this all the time in JavaScript, and of course, in PHP. PHP booleans, for example, can surprise you: 0 is false, which is a common enough assumption, but so is "0"- the string zero. As are empty arrays.

But what if you wanted more control over it? Peter sends us this PHP he found:


Sanitary Paths

When accepting user input for things like, say, accessing the filesystem, you need to do some validation. Bad or inappropriate characters could lead to surprises that no one is going to like.

So when Christian first spotted this C# method called SanitizePath, he didn't think much of it. But then he looked at the implementation…

Maciek has the distinct pleasure of working on Dynamics Ax, and ERP system. Like every other ERP system, it's endlessly customizable, and scriptable. In this case, scriptable in a custom language called "X++".

While it's probably entirely possible to write good code under these circumstances, it's not an environment conducive to that. And that's how Maciek inherited this method:


Uniquely Enough Identifiers

Running and hosting a database is expensive. Not only do you need the server for it (even if you rent in the cloud), you also need the expertise to administer it. And that's why Lucas ended up working on an application which used Google Sheets as its database.

Now, this was an application used by a marketing team to create new marketing campaigns, so Google Sheets wasn't the worst choice made in the entire process. With only a handful of users and dozens of records, it was fine. You didn't need to put a huge amount of effort or expertise into it- at least, that's what management thought.

This week, we saw some unexpected results in UK politics. Nothing was more unexpected than the dark-horse results that Richard and a few anonymice remarked on.

"A glorious victory for the Undefined party!" crowed Richard "The UK general election has seen a surge of support for minor parties."

Reliability is its own, very important art. Unless you're, say, Google, you shouldn't write your own reliability systems, but instead buy solutions from a vendor. Just not this vendor. Original. --Remy

Image credit: 'Mark Bowytz' - REMEMBER THE KRAKEN!!!It was a little past 4AM when Massimo's support pager went off, jarring him awake. Without even looking at the pager or logging into his laptop, he flipped on the television to Channel 242: the Video on Demand channel for the Italian TV broadcaster that he worked for.

Nothing.
