Oscar Night is a few weeks away, but when you settle in to watch the show with your bowl of popcorn, please be aware that inhaling deeply from the fumes of a freshly-opened bag of microwave popcorn is not the greatest decision you can make from a health standpoint. (Then again, you probably ought to reconsider eating microwave popcorn in the ...

It's fine to use fibers, but everybody has to be on board with the plan

We saw fibers a long time ago when I looked at how you can use fibers as a form of coroutines to simplify the writing of enumerators. A fiber is a handy tool, but it's a tool with very sharp edges. Since fibers are promiscuous with threads, you have to be careful when running code that cares about what thread it is running on, because that ...

Food products that are offenses against nature: Bagel-fuls

Wow, it's been a long time since my last rant against food products that are offenses against nature. Today's rant is against Bagel-fuls, a product which Kraft launched in April 2008. Bagel-fuls (note the hyphen and the lowercase "f") are a dense, doughy material formed into a log shape, with a cream cheese filling. Think of them as ...

What happens to the fibers which ran on a thread when the thread exits?

What happens to the fibers which ran on a thread when the thread exits? Are all the fibers destroyed? No, only the currently-executing fiber is destroyed. Fibers running on other threads and fibers which are not running on any thread at all are not affected. Fibers do not have thread affinity (when not running), and they do not remember what...

Le Chatelier's principle in action: Announcements

Raymond Chen
As I noted some time ago, one of the most important lessons I learned from Systemantics is Le Chatelier's Principle for complex systems which states, "Every complex system resists its proper functioning." At Microsoft, there are processes galore. For example, when a server is taken down for planned maintenance, you can expect a series of ...

SuperBK asks, "What's the proper way to add keyboard support to a dialog box?" There are many options available to you. The most traditional way is to pick them off in the dialog loop, either hard-coding the keys in code or putting them into resources by moving them to an accelerator resource. Moving them to an accelerator resource is a ...
