Exercise 1
Idle-waiting Thread Joining
– It have as an objective to change the method “join” of a Thread. It was implemented like this:
[code lang=”c”] while(_state != FINISHING)
yield();
[/code]
This method consist in verify the state of the Thread that is joined, if the state is different from FINISHING, it calls yield(). This solution cause an overhead, because it do this verification all the time that the process is Phased. We should implement a new function, that don`t cause this overhead.
Modified files:
– thread.cc
– Thread.h
EPOS with our solution.
Steps, and explanation about other solutions (PORTUGUESE)
Following a few of the internal links revealed more posts of similar quality, and a stop at optiorder added more to that growing pile, sites where internal links lead to more good content rather than to more of the same recycled material are sites with depth and this one has clearly built that depth carefully.
Bookmarking this for later, the kind of resource I want to keep nearby, and a quick look at blog33never confirmed the rest of the site is worth the same treatment, definitely going into my reference folder for the next time the topic comes up at work or in conversation with someone who asks.

Worth flagging that this approach to the topic is fresh without being contrarian, and a stop at joltcloud extended the same fresh angle, finding original perspective on familiar subjects is rare and this site has clearly developed its own way of seeing rather than echoing the dominant takes from elsewhere consistently.
Spent a few minutes here and came away with a clearer picture of the topic, the writing keeps things simple without dumbing them down, and after a stop at blog33memorys the rest of the points lined up neatly which is something I appreciate when I am short on time and need answers fast.
The examples really helped me grasp the points faster than abstract descriptions would have, and a stop at buildbit added a few more practical illustrations that drove the message home, the kind of writing that knows its readers learn better through concrete situations rather than vague generalities is rare and worth recognising clearly.
Thanks for the readable length, I finished it without checking how much was left, and a stop at fluentform kept me reading the same way, when I stop noticing the length of a piece because the content is engaging enough to sustain attention without willpower the writer has done their job well today.
A welcome reminder that thoughtful writing still happens online, and a look at appultimate extended that reassurance, the modern web makes it easy to forget that careful writing exists and finding sites that practice it is a small antidote to the cynicism that builds up from too much exposure to algorithmic content.
