He's often on stage, doing improv comedy, but insists that he isn't doing comedy- it's deadly serious. You're laughing at him, not with him. That, by the way, is usually true- you're laughing at him, not with him.

Featurette: Hired!

As you know, Hired has been sponsoring the site for the past few months. I went “behind the scenes” to have a brief chat with Michael Mitchell, a full stack web engineer focused on their “Candidate Experience” features.

Object Relational Mangling

Writing quality database code is a challenge. Most of your commands need to be expressed in SQL, which is a mildly complicated language made more complicated by minor variations across databases. Result sets often have a poor mapping to our business logic’s abstractions, especially in object-oriented languages. Thus, we have Object-Relational-Mapping tools, like Microsoft’s EntityFramework.

With an ORM, you use an object-oriented approach to fetching your objects, and could write something like: IList<HJFRate> rates = db.HJFRates.where(rate=>rate.typeOfUse == typeOfUse) to return all the rows as objects. There’s no concern about SQL injections, no need to process the result set directly. While ORMs can generate poor SQL, or create really inefficient data-access patterns, their ease-of-use is a big selling point.

Attack of the "i" Creatures

Mrs S” works for a large software vendor. This vendor has a tendency to quickly increase staffing to hit arbitrary release targets, and thus relies heavily on contractors. Since they’re usually doing this during a time crunch, these contractors may have a… dubious skill set.

They also don’t care. There is no documentation, no tests, and no explanation. They are just paid tho write the code, not maintain it. They’ll be on another contract before long, so it’s some other schmuck’s problem.

Protect Your Property

by in CodeSOD on

Given the common need to have getter/setter methods on properties, many languages have adopted conventions which try and make it easier to implement/invoke them. For example, if you name a method foo in Ruby, you can invoke it by doing: = 5.

In the .NET family of languages, there’s a concept of a property, which bundles the getter and setter methods together through some syntactical sugar. So, something like this, in VB.Net.

Drop it Like it's a Deployment

Zenith’s company went ahead on and outsourced 95% of their development to the lowest bidder. Said bidder promised a lot of XML and MVC and whatever TLAs sounded buzzwordy that day, and off they went. It’s okay, though, the customer isn’t just taking that code and deploying it- “Zenith” gets to do code reviews to ensure code quality. The general flow of the post-code-review conversation goes something like:

Zenith: This code shouldn’t go into production, hell, it’s so bad that a proud parent wouldn’t even hang it on their fridge.
Management: I’ll raise your concerns.
Outsourced Team: We did the needful, please review again.
Zenith: They didn’t change anything. It doesn’t even compile.
Offshore Team: There are too many barriers, we cannot hit deadlines, your team is too strict
Managment: Yeah… I guess you’re gonna have to lay off the contractors. Don’t be so strict in your code reviews. We have to deliver software!

Nature In Its Volatility

About two years ago, we took a little trip to the Galapagos- a tiny, isolated island where processes and coding practices evolved… a bit differently. Calvin, as an invasive species, brought in new ways of doing things- like source control, automated builds, and continuous integration- and changed the landscape of the island forever.

Geospiza parvula

Or so it seemed, until the first hiccup. Shortly after putting all of the code into source control and automating the builds, the application started failing in production. Specifically, the web service calls out to a third party web service for a few operations, and those calls universally failed in production.

Synchronized Threads

Tim was debugging one of those multithreading bugs, where there appeared to be a race condition of some kind. The developer who had initially written the code denied that such a thing could exist: “It’s impossible, I used locks to synchronize the threads!”

Well, he did use locks at the very least.

Groovy Typing, Man

by in Representative Line on

Groovy was one of those programming languages that spent about six months as the trendy language du jour, and I haven’t heard much about it since. If I were to learn it, I’d want to learn by example- going through real-world Groovy code and seeing how it works.

An anonymous submitter has provided one sample for me to learn from:
