I am frankly disturbed by a trend that I’ve seen both in-person and all over Hacker News / Reddit through the past year, and I am going to finally give it a name: “popped collar programming.”
Popped collar programming is the hipsterization of software development, and it’s happening in a co-working space, unprofitable venture-backed startup, or coffee shop near you.
A popped collar programmer’s life begins like this:
[New Technology X] is released and offers a new and interesting view of how to perform [programming chore Y];
Reddit / Hacker News announces the release of [New Technology X] and is greeted with tons of enthusiasm and applause;
Curious developers check [New Technology X] out – it’s an early release and thus they discover [New Technology X] is missing [Critical Features 1….N] and has [Stability Issues 1…N]; most of the early adopters utilize the technology...
I spent a lot of time late last week trying to figure out exactly how to set up dependency injection for a WCF service I was developing on Windows Azure; there’s some documentation out there on how to do it, but it’s not nearly as helpful as I would like it. Thus I decided to document how I made WCF and Ninject play nice with each other, and I even provide a sample template you can use yourself.
Step 1 – Install Ninject.Extensions.WCF via NuGet
The developers who maintain Ninject were kind enough to put together a set of extensions for working with WCF applications specifically, and we can install this via NuGet (install it from CodePlex.)
Simply type this into the “package manager console” in Visual Studio: install-package Ninject.Extensions.Wcf
I announced this on Twitter late last week, but I open-sourced a number of common helpers and service interfaces that I use throughout all of my production ASP.NET MVC applications and wrapped it into a project I call MVC.Utilities.
MVC.Utilities has a number of helper classes for the following:
- Security for user-uploaded files;
- and display helpers for things like Hacker News-style datetimes.
If you want more details and examples of what the library does exactly, be sure to check out the MVC.Utilities Wiki on Github. All of these services are meant to be Dependency-Injected into ASP.NET MVC controllers and are designed as such.
The library has a lot of room to expand and grow, and I encourage your ideas and contributions to the project! Just create a fork of MVC.Utilities on Github and send me a pull request; props to...
The LA startup scene is fascinating, having lived and worked in it for a year now - it's a scene teeming with brillaint people with big ideas, and it's starting to attract some major capital from the Bay Area. It has one major issue: a big shortage of technical co-founders.
As a result, people like me get approached fairly regularly by companies that are either trying to recruit me or recruit through me - the vast majority of the time it's a pair of non-technical co-founders looking to third founder aboard, a technical cofounder, to build the MVP prior to raising some money. In my personal experience, the majority of pitches I've received have been poorly calculated and in need of much improvement.
Speaking as a former and future technical founder, I wanted to share my perspective on what non-technical (and technical, for that matter) founders could do differently to...
One of the first projects I put together this year was Captain Obvious, a nifty little application that runs off of AppHarbor and ASP.NET MVC3. What made Captain Obvious special for me was that it was my first time using something other than a relational database[footnote: typically I’ve only used SQL Server / MySQL in the past] in production – I chose MongoDB because it stands out to me as a lightweight, easy-to-work with store that’s easier to use for most CRUD applications. Since then I’ve gone on to build other projects which depend on Mongo.
What I’ve learned since is that MongoDB and SQL Server are tools that aren’t 100% interchangeable and are more situational than dogmatists make them out to be.
My goal in writing this is to help inform you on how you should decide to judge these two technologies as options for...
One of the more interesting things I had to do as part of building XAPFest was handle bulk image uploads for screenshots for applications and user / app icons. Most of the challenges here are UI-centric ones (which I resolved using jQuery File-Upload) but the one security challenge that remains outstanding is ensuring that the content uploaded to your servers is safe for your users to consume.
Fortunately this problem isn't too hard to solve and doesn't require much code in C#.
Flawed Approaches to Verifying Image Uploads
Here's what I usually see when developers try to allow only web-friendly image uploads:
- File extension validation (i.e. only allow images with .png, .jp[e]g, and .gif to be uploaded) and
- MIME type validation.
So what's wrong with these techniques? The issue is that both the file extension and MIME type can be spoofed, so there's no guarantee that...
I made a tiny splash on Hacker News a month ago when I asked for feedback on my newest side project, CaptainObvio.us – a simple portal for sharing ideas and soliciting feedback from a community of peers. The idea was popular and I’ve received a ton of feedback – I’ve implemented most of the Hacker News community’s suggestions but haven’t had the chance to do another round of customer development.
What I wanted to share in this blog post was some of the secret sauce I used for creating CaptainObvio.us – I originally created it mostly to learn MongoDB, and learned way more than that along the way.

I used ASP.NET MVC3 as my webstack of...
I am pleased to announce something very exciting that Microsoft is doing in my neighborhood of Santa Monica, California: we’re putting together XAPFest, a massive Windows Phone 7 hackathon aimed to bring together startups and mobile developers of all skill levels for a day of creativity and competition.
XAPFest is going down on Saturday, June 4th at the Loews Santa Monica Beach Hotel (directions) – doors open at 9:00am and will close at approximately 10:00pm. There will be opportunities for individuals and teams of developers to win prizes, eat great food, and have fun hacking down by the beach.
XAPFest is free to attend, and anyone can register for XAPFest if they wish to participate....
Tonight I gave a brief talk to WinMo LA about using Geolocation Services and Bing Maps on Windows Phone 7. I mostly covered the APIs and controls that developers can use in the current Windows Phone SDK, the steps developers need to take in order to protect a user's data, and some of the future things that are changing in Mango for Windows Phone 7 developers.
Source Code for Demos:
I spent about three hours banging my head against the wall trying to figure out why my browser could connect to the Internet but the Windows Phone 7 emulator couldn’t, and if you find yourself in the same boat as me I thought I would spare you the trouble.
Are you seeing something like this when you try to pull up a web page in IE on the emulator?
If that’s the case, then you’re having network connectivity issues specific to the Windows Phone 7 emulator. There’s a guide to troubleshooting Windows Phone 7 emulator issues on MSDN, and it speaks to the root of the issue: your HTTP proxy settings.
If you’re like me, you like using Fiddler for testing network I/O when you’re trying to connect...
