I know that Rome empties out in August, but if any Joel on Software readers plan to be there on Monday, August 16th, it would be nice to get together for dinner. So far, we’ve done these dinners in Berkeley, Oslo, and Montréal, with great success. We’ll take over a room in a restaurant, eat, drink, be merry, and talk about software development. If you can attend, or would like to suggest a good place to meet, post a message here.

Marshall T. Rose, in RFC 3117: “Counter-intuitively, Postel’s robustness principle (‘be conservative in what you send, liberal in what you accept’) often leads to deployment problems. Why? When a new implementation is initially fielded, it is likely that it will encounter only a subset of existing implementations. If those implementations follow the robustness principle, then errors in the new implementation will likely go undetected. The new implementation then sees some, but not widespread deployment. This process repeats for several new implementations. Eventually, the not-quite-correct implementations run into other implementations that are less liberal than the initial set of implementations. The reader should be able to figure out what happens next.”


One of the biggest weaknesses of Microsoft Outlook has been the search feature. It takes so long for Outlook to search that the feature is almost useless.

Searching is not a hard problem, and a lot of plug-ins sprang up to solve this problem. Lookout was one of the best. It just works. Searching five years of accumulated email takes less than a second. Indexing is done quietly in the background and never slows down your system. Suddenly email is useful again.

So what happens? Microsoft buys Lookout. That’s nice, good for them.

But look more closely at the Q&A:

Q: Why can’t I download Lookout anymore?

We will be focusing our efforts on integrating our expertise and working on next-generation technologies.

Huh? What’s going on?

Q: What is Microsoft going to do with Lookout? …

The existing Lookout product will no longer be available, but its technology will be part of an exciting vision that MSN has for delivering new and innovative search services.

MSN?! Lookout is going to be part of MSN? What about Outlook?

Our vision is to take search beyond today’s basic Internet search services to deliver direct answers to people’s questions, and help them find information from a broad range of sources.

What? What the hell does this have to do with searching email? Could Microsoft have possibly bought Lookout just to shut them down? Even at my most paranoid, I can’t for the life of me figure out why Microsoft wants searching in Outlook to be worthless. Maybe just Hanlon’s Razor: “Never attribute to malice that which is adequately explained by stupidity.”

Update: They figured it out on the discussion group. Lookout is using an open-source component for searching, which Microsoft can’t redistribute. The only part of Lookout that Microsoft allegedly cares about, the search engine, is released under the Apache license. The only part of Lookout which Microsoft can use is the Outlook integration, and they don’t seem to care about that. Methinks this is one of those “HR Acquisitions,” wherein Microsoft buys a company for a few bucks because it’s the only way to hire someone they want.


Ah, finally, my second book is on its way to the printer.

Yes, it’s mostly reprints of articles which you’ve already read on this site over the last four years. But there are three huge advantages to the book version. 1) It has been professionally edited. I have finally learned to use semicolons instead of commas to separate complete sentences, and somebody smarter than me has sorted out all the “whiches” and the “thats.” 2) You don’t have to read it on a computer. 3) You can hurl it at your boss or coworkers to make a point, and the impact will be much more powerful than emailing a URL.

I’m hoping it will be out in a month or so.
