"When we talk of “white men” we are describing an institution."
- Sara Ahmed, White Men

If you haven't read Sara Ahmed, you're missing out.

Her essay "White Men" goes a long way to making sense of how institutions work, and how their behaviours diverge from their stated mandates.

I read this essay 8 1/2 years ago and I have never stopped thinking about it.

GASP Executive Director Jilisa Milton said she wasn’t surprised, noting the application had referenced helping Black residents disproportionately harmed by nearby coke plants. The EPA’s termination letter cited a shift in agency priorities, stating the award “no longer effectuates the program goals.”

This redesign of #poser (for #swad) to offer a "multi-reactor" (with multiple #threads running each their own event loop) starts to give me severe headaches.

There is *still* a very rare data #race in the #lockfree #queue. I *think* I can spot it in the pseudo code from the paper I used[1], see screenshot. Have a look at lines E7 and E8. Suppose the thread executing this is suspended after E7 for a "very long time". Now, some dequeue operation from some other thread will eventually dequeue whatever "Q->Tail" was pointing to, and then free it after consumption. Our poor thread resumes, checks the pointer already read in E6 for NULL successfully, and then tries a CAS on tail->next in E9, which is unfortunately inside an object that doesn't exist any more .... If the CAS succeeds because at this memory location happens to be "zero" bytes, we corrupted some random other object that might now reside there. 🤯

Please tell me whether I have an error in my thinking here. Can it be ....? 🤔

Meanwhile, after fixing and improving lots of things, I checked the alternative implementation using #mutexes again, and surprise: Although it's still a bit slower, the difference is now very very small. And it has the clear advantage that it never crashes. 🙈 I'm seriously considering to drop all the lock-free #atomics stuff again and just go with mutexes.

Some notes:

* The curve gets worse as you run faster. I can really feel it in my hips, calf and ankles. (We flipped directions every 30min)
* Reflection from water in the fountain made it feel even hotter!
* Since the aid station is self-help, it took more time to drink/refuel than ordinary races.
* Navigating around slower runners becomes more taxing when running in circles.

Thank you @nickwalker for organizing another successful #UW #Drumheller #race!
