Every time I go to conferences, especially #fosdem, I feel physically exhausted but mentally boosted.

It was really nice to meet the Hachyderm volunteers in person at #fosdem. The BoF concept was perfect.

I'm also crying because I've missed one of the sessions I wanted to see. Fortunately, the event is just starting. I've plenty of time to see other awesome sessions #fosdem

I don't know what keystrokes I use on firefox but, from time to time, my long hard manually typed URL is being replaced by the preferences tab (about:preferences#search). This is very annoying because I need to retype something I've already typed.

Now that the fun part of my "side project" at work is finished, I can retry to set up a pixelfed instance at home. But the weekend is almost over and my todo list is already full 😅

I really hope that Instagram to Pixelfed migration will bring more tattoo artists to the fediverse because I'm sick of opening this goddamn app

I'm having fun with Go channels! That fsnotify module where file changes are detected and configuration is refreshed instantaneously. And signal notifications to handle graceful shutdowns. This is amazing.

The solution looks like this:

for {

    select {

    case <-ctx.Done():

        // cancelation work

        return

    default:

        run()

        time.Sleep(...) // remove WithContext

    }

}

I may know where the CPU cycles are spent. There's a select statement waiting for a context to be canceled and a for loop with a sleep function taking a context too. The sleep is skipped when the context is closed but the infinite loop doesn't end. I should move the for loop outside of the select and use the regular sleep function. Let's see that tomorrow 💡

My current Go program has a bug when I cancel a context, the CPU goes wild without stopping what's supposed to be stopped. Simple context/select statements are easy but they could become a nightmare in real world applications. Last time my CPU spiked, it was caused by an infinite loop without a sleep statement.

I've finally understood how to use Go contexts and select statements 💪🏻
