Being an open recipient

Lately, I’ve been reading One Strategy: Organization, Planning, and Decision Making. It’s a collection of Steven Sinofsky’s internal blog posts while he ran the Windows division, with some light analysis by Marco Iansiti. (The blog posts are so far more interesting than the analysis.)

This quote stuck with me (page 30, Kindle location 746):

We are still not sending around (locally) enough meeting notes and not sharing information more freely. And part of that is asking people to be more receptive to “raw data” and less demanding of “tell me what is important” because with empowerment comes the need to process more data and manage the flow of information. For our process to work smoothly we do need more communication.

Within Readify, we’re seeing a fast growth of shared OneNote notebooks. They’re like wikis on steroids: near real-time multi user editing, ink, images, audio, no save button, multi-device, offline support, web app, deep linking right down to a specific paragraph, and more. They’re an insanely useful part of our information flow, and deserving of their own post another time.

The ease of access that comes with these pervasive notebooks has lowered the bar for content capture. And it’s great.

Instead of some formal documentation requirement that gets missed, we’re now able to capture the as-it-happens notes. After 10 years of consulting, we’re finally seeing a really rich knowledge base about our engagements get synchronized back into SharePoint instead of living in the heads of individual consultants. Call notes, meeting notes, architecture diagrams, sprint reviews, pre-sales meetings, org charts and whiteboard photos all end up in the notebook now. When I go to a presales meeting, the account manager and I are both recording our different notes straight into the same page of a notebook in real-time, then one of us can snap a pic of the whiteboard as we leave. (SharePoint + 4G enabled devices are the back-end plumbing here.)

These notes don’t provide the full context of a project, but they capture a series of events that cumulatively provide much of that context. They aren’t an analysis of the events either; they’re a summary, closer to a transcript. But that’s all ok, because they create visibility across our teams and open conversations we weren’t having before. Seeing this transition sweep across our business, I have to say that I wholeheartedly agree with Steven’s views.

Shaving a Yak, Beside the Bike Shed

Because this is being posted to the Big Bad Internet™, I feel the need to disclaim up front that these terms are not my own, nor are my definitions necessarily the canonically ‘correct’ ones. If you get to the end of the post though, you’ll see that that doesn’t matter. This post is one of hopefully a few, where I capture some known ideas but with my own style and analysis. This is primarily being driven by a desire to give some common concepts that I discuss a home that I can link to, where existing descriptions around the internet may not capture my exact personal views.

A mark of maturity that I’ve noticed in effective teams is an evolved language: they have their own catch phrases, and shortcuts that make communication so fast and efficient within the team. Intention is clear, ambiguity is reduced, and people spend less time analysing subtext that isn’t there.

This culture of communication is heavily rooted in strong interpersonal relationships, which do take some time. However, I’d like to argue that we can actively develop some of this communication culture.

Last month, I spent a week with a software engineering team in New Zealand. Their organisation is in the early stages of trying some big, bold, new ideas, and this team needs to support these somehow. The roadmap is still a little fuzzy, but everyone appreciates that they have a lot of work ahead of them. Success will be heavily influenced by spending the just the right amount of time on the right things, but this is a perilously thin path to success with cliffs and chasms everywhere they look.

To stay in check, everyone on the team needs to feel comfortable to question the validity or extent of a task. Equally, they need to still feel comfortable when on the receiving end of such a question. In many teams, this question might come across with phrases like “Isn’t that enough already?”, or “Is this gold plating?” These often come across as confrontational though, seeming to cut away at the value of the work that somebody has been doing. There are nuances open to interpretation, because as obvious as they may seem, the intent of the phrases is not necessarily clear.

I introduced the team to two new phrases:

Yak Shaving

Your home office chair is making an annoying creaking sound because of a loose bolt. You could tighten it easily, except it uses a hex head and you lent your bit set to your neighbour. You can’t ask for them back, because you first need to return something to him: a special anti-allergy pillow that you borrowed for a friend who was staying last week. But you can’t just return the pillow either, because the dog got into it and ripped half the stuffing out. You don’t want to tell him, because it’s filled with a special yak fur that’s hard to come by, which he needs for his son when he visits: you want to fix it yourself first.

The next thing you know, you’re down at the local zoo, shaving a yak, all to stop a squeaky chair.

All of the decisions to get there were individually justified, but at some point you drift too far away from the original goal for them to still make sense as a whole chain. Just buy a new bit set, or give him some money for a new pillow. Or both. But don’t go and shave a yak.

As Seth extrapolates in his description:

This yak shaving phenomenon tends to hit some people more than others, but what makes it particularly perverse is when groups of people get involved. It’s bad enough when one person gets all up in arms yak shaving, but when you try to get a group of people together, you’re just as likely to end up giving the yak a manicure.

Bike Shedding

This one is from Parkinson’s Law of Triviality, and Wikipedia’s summary is best:

Parkinson observed that a committee whose job is to approve plans for a nuclear power plant may spend the majority of its time on relatively unimportant but easy-to-grasp issues, such as what materials to use for the staff bikeshed, while neglecting the design of the power plant itself, which is far more important but also far more difficult to criticize constructively.

Back with the Team

These two phrases each provided distinctly nuanced versions of the original question.

In the way I try to introduce these phrases, “Are we yak shaving here?” says “I can see all the decisions you’re following, and they all seem legitimate. Standing back here though, with a fresher set of eyes, do you think we are drifting a bit too far from the original goal?” Slightly differently, “Are we bike shedding?” is an explicit call of triviality, but recognizing that it’s an easy trap.

Your team’s definitions can vary; what’s more important is that we had a conversation about how we’d communicate. We took a funny story about yaks, and used that to define some phrases that were relevant to the team. Now, when the team hit these scenarios, they can use one of these phrases knowing that the nuances have been pre-discussed and agreed on.

In truth, in this scenario I actually only told these stories to two members of the team. Within a few hours though I heard them describing their own variants of the story to others. That’s another thing that’s great about these types of communication devices: humans communicate better with stories than dry, independent facts. (You might notice, that for this entire blog post, I just told you a story. J)

Podcast: Graph databases and Neo4j, with Richard and Carl from .NET Rocks!

Listen to .NET Rocks! #949

This is what happens when you phone me up at 6am on a Saturday morning: you get a surprisingly energetic Tatham babbling about discussing Neo4j and graph databases for an hour. There are even some nice bird sounds in the background towards the end, as they finally woke up too.

We discussed what graph databases are (as opposed to charts!), some domains where you might use one, how they relate to other stores like document and relational databases, query performance, bad database jokes, my obsession with health data (,, the Cypher query language, ASCII art as a job, Readify/Neo4jClient for the .NET folks, and some Neo4j+NewRelic.

Useful? Help the Children.

If this podcast was useful to you, perhaps you could donate to my next charity cycle? I’ll be cycling the first leg of the 26 day, 3,716km Variety cycle. Variety, the Children’s Charity is a a national not-for-profit organisation dedicated to transforming the lives of children in need. Variety’s vision is for all children to attain their full potential; regardless of ability or background – and their mission is to enrich, improve, and transform the lives of seriously ill, disadvantaged and special needs children., and good ways to learn new tech stacks

Besides just being a cool domain name, it’s actually quite a useful tool. Wondering how your code responds to an HTTP 418 response? Point it at and find out.

Aaron and I originally built this as a way of learning Ruby, Sinatra, HAML, Sass, Git, Heroku and other funky tool chains. Several years on, left unmaintained, something about our app finally made it incompatible with Heroku’s hosting layer and it all shutdown. Our singular name really rang true here: every request returned a 503. Oops. We already had an ASP.NET-based re-write waiting in the wings, so we pushed that up to Windows Azure Websites and everything came humming back to life.

Want to learn a new tech stack or tool chain? Skip the contrived examples and actually build something simple. It’s amazing how often these turn into cool little tools that stick around for time to come.

Web Forms MVP: Now with less cobwebs

TL,DR: is now just a redirect to

Back in early 2009, Damian and I released our first builds of Web Forms MVP.

GitHub and BitBucket were each less than 6 months old. CodePlex was the place to be for .NET devs, and I think our code was originally in either Subversion or TFS. We needed a wiki, but CodePlex was pretty clunky for that, so we set up a MediaWiki instance on a tiny VM somewhere, running inside Microsoft Virtual Server 2005. Funnily enough, this was all getting pretty unstable. Our wiki has been down almost 50% of the time in recent weeks.

Personally, I was actually a little bit surprised about how many people cared that the wiki was unavailable. This was a promising sign, so we needed to fix the problem.

Today, we migrated to GitHub.

  1. Code was converted from Hg to Git, then pushed to GitHub
  2. Wiki content was converted from MediaWiki to Markdown, then pushed to GitHub wiki
  3. Release notes were migrated to GitHub releases, against the same tags
  4. was redirected to
  5. CodePlex was gutted of content wherever possible, and changed to link to GitHub

The project is still classed as “done” for Damian and I (see my Dead vs. Done post). While we’re not actively investing time in any further versions, publishing it to GitHub gives more reliable access to the content, and makes it easier for the community to fork the project as they see fit.

An Approach for More Structured Enums

The Need

I encountered a scenario today where a team need to increase the structure of their logging data. Currently, logging is unstructured text – log.Error("something broke") – whereas the operations team would like clearer information about error codes, descriptions and accompanying guidance.

The first proposed solution was a fairly typical one: we would define error codes, use them in the code, then document them in a spreadsheet somewhere. This is a very common solution, and demonstrated to work, but I wanted to table an alternative.

This blog post is written in the context of logging, but you can potentially extend this idea to anywhere that you’re using an enum right now.

My Goals

I wanted to:

  • support the operations team with clear guidance
  • keep the guidance in the codebase, so that it ages at the same rate as the code
  • keep it easy for developers to write log entries
  • make it easy for developers to invent new codes, so that we don’t just re-use previous ones

A Proposed Solution

Instead of an enum, let’s define our logging events like this:

public static class LogEvents
    public const long ExpiredAuthenticationContext = 1234;
    public const long CorruptAuthenticationContext = 5678;

So far, we haven’t added any value with this approach, but now let’s change the type and add some more information:

public static class LogEvents
    public static readonly LogEvent ExpiredAuthenticationContext = new LogEvent
        EventId = 1234,
        ShortDescription = "The authentication context is beyond its expiry date and can't be used.",
        OperationalGuidance = "Check the time coordination between the front-end web servers and the authentication tier."
    public static readonly LogEvent CorruptAuthenticationContext = new LogEvent
        EventId = 5678,
        ShortDescription = "The authentication token failed checksum prior to decryption.",
        OperationalGuidance = "Use the authentication test helper script to validate the raw tokens being returned by the authentication tier."

From a consumer perspective, we can still refer to these individual items akin to how we would enums – logger.Error(LogEvent.CorruptAuthenticationContext), however we can now get more detail with simple calls like LogEvent.CorruptAuthenticationContext.EventId and LogEvent.CorruptAuthenticationContext.OperationalGuidance.

More Opportunities

Adding some simple reflection code, we can expose a LogEvents.AllEvents property:

public static IEnumerable<LogEvent> AllEvents
        return typeof(LogEvents)
            .GetFields(BindingFlags.Static | BindingFlags.Public | BindingFlags.DeclaredOnly)
            .Where(f => f.FieldType == typeof(LogEvent))
            .Select(f => (LogEvent)f.GetValue(null));

This then allows us to enforce conventions as unit tests, like saying that all of our log events should have at least a sentence of so of operational guidance:

[TestCaseSource(typeof(LogEvents), "AllEvents")]
public void AllEventsShouldHaveAtLeast50CharactersOfOperationalGuidance(LogEvents.LogEvent logEvent)
    Assert.IsTrue(logEvent.OperationalGuidance.Length >= 50);

Finally, it’s incredibly easy to either list the guidance on an admin page, or generate it to static documentation during build: just enumerate the LogEvents.AllEvents property.

The Code

I’ve posted some sample code to

Something interesting things in that repository are:

  • I’ve split the ‘framework’ code like the AllEvents property into a partial class so that LogEvents.cs stays cleaner.
  • I’ve written some convention tests that cover uniqueness of ids and validation of operational guidance.

Wrap Up

There’s absolutely nothing about this solution that is technically interesting. It’s flat out boring, but sometimes those are the most elegant solutions. Jimmy already wrote about enumeration classes 5 years ago.

Dead vs. Done

Back through 2009 and 2010, Damian Edwards and I worked on a project called Web Forms MVP.

It grew out of a consistent problem that we saw across multiple consulting engagements. We got tired of solving it multiple times, so we wrote it as a framework, released it open source, and then implemented it on client projects (with client understanding). Clients got free code. We got to use it in the wild, with real load and challenges. We got to re-use it. The community got to use it too.

It has been downloaded 20k+ times, which is pretty big considering it was around before NuGet was. (Although, we were one of the first 25 packages on the feed too.)

In the last 12 – 18 months, I’ve started seeing “Is Web Forms MVP dead?” being asked. This blog post both answers that question directly in the context of Web Forms MVP, but also discusses the idea of dead vs. done.

Here’s a specific question I was asked:

I am a little bit worried about the fact there is not code commit since sept 2011. Will you continue the project or will it fall in the forgotten ones?

And here was the answer I wrote:

I have a mixed answer for you here.

On the one hand, we cut seven CTP builds, then a v1.0, then a 1.1, 1.2, 1.3 and 1.4. That means we developed the library, tested hundreds of millions of production web requests through it, reached a feature point we wanted to call 1.0, then iterated on top of it. In the 15 months since cutting 1.0, there are only six issues on the Codeplex site: one is a question, one a misunderstanding, one a demo request, and one a feature request that I don’t really agree with anyway.

At this point, Web Forms MVP 1 is “done”, not “dead”. I’m just slack about closing off issues.

Now, that opens up some new questions:

If you find a bug with 1.4 that you can’t workaround, are you left out in the cold? No. First up, you have all the code and build scripts (yay for open source!) so there’s nothing we can do to prevent you from making a fix even if we wanted to (which we never would). Secondly, if you send a pull request via Codeplex we’ll be happy to accept your contribution and push it to the official package.

Will there be a Web Forms MVP 2? At this time, from my personal perspective, I’ll say ‘highly unlikely’. As a consultant, I haven’t been on a Web Forms engagement in over 2 years. That’s not to say there isn’t still a place for Web Forms and Web Forms MVP, but that I’m just not personally working in that area so I’m not well placed to innovate on the library. Damian has lots of great ideas of things to do, and since starting Web Forms MVP has actually become the Program Manager for ASP.NET Web Forms at Microsoft. That being said, his open source efforts of late are heavily focussed on SignalR.

Should there be a Web Forms MVP 2? Maybe. It’d be nice to bring it in line with ASP.NET 4.5, but I’m hard placed to know what is needed in this area considering I’m not on a Web Forms engagement. Without a clear need, I get rather confused by people calling for a new version of something just so they can feel comfortable that the version number incremented.

I hope that gives you some clarity and confidence around what is there today, what will stay, and where we’re going (or not going).

Some projects definitely die. They start out as a great idea, and never make it to a release. I find it a little sad that that’s the only categorisation that seems to be available though.

I hope I’m not just blindly defending my project, but I do genuinely believe that we hit ‘done’.

From here, Web Forms MVP might disappear into the background (it kind of has). The community might kick off a v2. A specific consumer might make their own fork with a bug fix they need. Those are all next steps, now that we’ve done a complete lifecycle.

In the meantime, people are asking if the project is dead, yet not raising any bugs or asking for any features. This just leaves me confused.

Upcoming Manila Presentation: Your website is in production. It’s broken. Now what?

Next month I’ll be spending some time in the Readify Manila office catching up with some local colleagues. While there, I’ll be presenting a user group session at the local Microsoft office. If you’re in the area, I’d love to see you there. (Did you know that we’re hiring in Manila too?)

Manila, Philippines, Wed 12th Dec 2012. Free. Register now.

Big websites fail in spectacular ways. In this session, five-time awarded ASP.NET/IIS MVP and ASP Insider Tatham Oddie will share the problems that he and fellow Readify consultants have solved on large scale, public websites. The lessons are applicable to websites of all sizes and audiences, and also include some funny stories. (Not so funny at the time.)

A tiny subset of your users can’t login: they get no error message yet have both cookies and JavaScript enabled. They’ve phoned up to report the problem and aren’t capable of getting a Fiddler trace. You’re serving a million hits a day. How do you trace their requests and determine the problem without drowning in logs?

Marketing have requested that the new site section your team has built goes live at the same time as a radio campaign kicks off. This needs to happen simultaneously across all 40 front-end web servers, and you don’t want to break your regular deployment cycle while the marketing campaign gets perpetually delayed. How do you do it?

Users are experiencing HTTP 500 responses for a few underlying reasons, some with workarounds and some without. The customer service call centre need to be able to rapidly evaluate incoming calls and provide the appropriate workaround where possible, without displaying sensitive exception detail to end users. At the same time, your team needs to prioritize which bugs to fix first. What’s the right balance of logging, error numbers and correlations ids?

Your application is running slow in production, causing major delays for all users. You don’t have any tools on the production servers, and aren’t allowed to install any. How do you get to the root of the problem?
