A couple of months ago, I mentioned a project I had coming up that might benefit from using Dependency Injection. The use-case on this is simple enough. We receive all of our EDI text files to a specific directory. Those files need to be processed into standard, internal temporary tables. Since each of our vendors uses the EDIFACT X12 fields differently, we need to customize parsing the files according to vendor.
This is actually one of the larger projects I undertake at our small in-house development shop so it needs more up-front architecture than most and it seemed like a...
I’ve been putting off a follow-up on Dependency Injection for a couple of months now. The amount of heat I anticipate receiving is so disproportional to the probable light gained that it makes me hesitate. This weekend, I picked up on a stream of referrals from a post at InfoQ that mentions my Dependency Injection post (though not the follow-ups). It does a reasonable job of spelling out the conversation that happened, though I was feeling picked on until it brought in Eli Lopian’s contribution to the discussion. In whole, it’s a good summary. The real pile-on happens in...
I’ve been musing about software architecture lately and trying to come up with a framework to help choose when to go with more as opposed to less—something that’ll help me feel less arbitrary in my choices. I mean, software design is something of a dark art, but how much of that is inherent and how much is simply being too lazy to formulate good internal guidelines?
My latest ruminations have revolved specifically around Inversion of Control in general and Dependency Injection in specific. Here’s the thing: for the development I do right now at a small reading glasses company, I’m reluctant...
I typically work with small companies who need to customize software to fit their business practices. A lot of companies have critical competitive advantages embedded in the way that they do things and need to ensure that their software doesn’t get in their way. That typically means that I deal with specific vertical markets (either at the vendor or client level) and dance with 500lb. gorillas to make things work the way companies expect them to. It’s business programming in the trenches and can be nasty, brutish, and, well, not short so much as constrained.
The Typical Battlefield
This is the...
In many companies developer career progression is deceptively straight-forward; Jr. Programmer, Programmer, Sr. Programmer, Team Lead, Architect, Sr. Architect, Bob (Bob being the semi-mythical entity referred to in obscure comments, worshipped by now-extinct aboriginal tribes, and rumored to haunt the sub-sub-basement).
The differentiation between these positions starts off with how much you know. A Sr. Programmer is a Jr. Programmer who knows his tools inside and out and can complete assigned tasks quickly and without a lot of supervision. Around Team Lead time, however, progression stops being about what you know and starts revolving around your ability to choose wisely...
