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)
Just want to flag that this was useful and not bury the appreciation in caveats, and a look at fashionlifestylehub earned the same direct praise, recognising good work without hedging it with criticism is something I try to practice because over qualified compliments tend to read as backhanded and miss the point sometimes.
Found this through a search that was generic enough I did not expect quality results, and a look at modernlivingemporium continued the surprisingly good experience, search engines occasionally still surface excellent independent content if you scroll past the obvious paid and high authority results which is reassuring to remember sometimes.

Reading this slowly in the morning before opening email, and a stop at lobbycommune extended that protected attention, content that earns the prime morning reading slot before the daily distractions begin is content with elevated status and this site has earned that prime slot consistently in my recent reading habits clearly.
Came away feeling slightly smarter than I was when I started, that is a real win, and a stop at edgedial added a bit more to that, the rare site that actually transfers some of its knowledge to the reader in a way that sticks rather than just creating an illusion of learning briefly.
Generally I bookmark sparingly to avoid building up a bookmark graveyard but this one earned a permanent slot, and a stop at mossbreeze extended that permanence designation, the few sites I keep permanent bookmarks for are sites I expect to use repeatedly and this one has clearly cleared that expectation bar today.
Once I trust a site this much I tend to read everything they publish and that is the trajectory I am on with this one, and a stop at evertrueharbor confirmed the trajectory, the rare progression from interested reader to comprehensive reader is something only certain sites earn and this one is earning that progression rapidly.
Found this really helpful, the explanations are simple but they actually answer the questions a normal reader would have, and after I followed northernriveroutlet I had a clearer sense of the topic, no extra fluff just useful points laid out in a sensible order that made the time worth it.
A piece that did not require external context to follow, and a look at draftlog maintained the same self contained quality, content that stands alone without forcing readers to chase prerequisites is more accessible and this site has clearly thought about how each piece can serve a fresh visitor rather than only existing members.
Saving the link for sure, this one is a keeper, and a look at trendforless confirmed I should bookmark the entire site rather than just this page, the consistency across what I have seen so far suggests there is a lot more here worth coming back for soon when I have more time.
Glad to have another reliable bookmark for this topic, and a look at classystyleoutlet suggested several more pages I will be marking too, building a personal library of trustworthy resources is one of the actual rewards of careful browsing and this site is earning a place on my permanent shortlist for the topic.
Found this via a link from another piece I was reading and the click was worth it, and a stop at grovequay extended the value across more material, the open web still rewards clicking through citations when the underlying writers care about each other work and this site clearly belongs to that network.
Took me time to read the material, but I truly loved the article. It turned out to be very useful to me.
Reading this gave me the rare experience of fully agreeing with all the conclusions, and a stop at lunarforesthub continued that agreement pattern, content that aligns with my existing views without seeming designed to do so is just content that happens to be reasonable and this site reads as reasonable rather than ideological mostly.
A thoughtful read in a week that has been mostly noisy, and a look at hazeatelier carried that thoughtful quality across more pages, finding pockets of considered writing in a week of distractions is one of the small wins of careful curation and this site is providing those pockets at a sustainable rate.

Started imagining how I would explain the topic to someone else after reading, and a look at changeyourmindset gave me more material for that imagined explanation, content that improves my own ability to discuss a topic is content that has actually transferred knowledge rather than just decorating my screen for a few minutes.
Came back to this an hour later to reread a specific section, and a quick visit to finduniqueproducts also drew a second look, content that pulls you back rather than letting you move on permanently is the kind I want to fill my browser bookmarks with in 2026 and beyond as the open internet evolves.
Reading this confirmed a hunch I had been carrying about the topic without having articulated it, and a stop at lacecabin extended the confirmation, content that gives shape to fuzzy intuitions is doing the rare work of making private thoughts public and this site is providing that articulating service consistently for me lately.
Well crafted post, the structure flows naturally from one point to the next without forcing transitions, and a stop at growtogetherstrong kept the same flow going, you can tell when a writer has thought about how their content reads rather than just what it contains and this is one of those examples.
I usually skim posts like these but this one held my attention all the way through, and a stop at brightcoastgallery did the same, that is a strong endorsement coming from me because I am usually quick to bounce when content gets repetitive or fails to deliver on its initial promise made in the headline.

Reading this in the time it took to drink half a cup of coffee, and a stop at mountainleafstudio fit naturally into the second half, content that respects the rhythms of a typical morning is content with practical fit and this site has the kind of length and pacing that works for the way I actually read.
Comfortable read, finished it without realising how much time had passed, and a look at flarefoil pulled me into more pages the same way, the absence of friction in good content lets time disappear and that is one of the highest compliments I can pay any piece of writing I find online during a regular search session.
Found something new in here that I had not seen explained this way before, and a quick stop at micapact expanded the idea even further, the kind of writing that nudges your thinking forward a bit without forcing the issue is exactly what I look for online today and rarely actually find anywhere.
Thanks for laying this out in a way that someone newer to the topic can follow, and a stop at flarefoil kept that accessibility going, writing that meets readers at different experience levels without condescending is hard to do well and the writers here have clearly thought about who they are writing for.
Looking through the archives suggests this site has been doing this for a while at this level, and a look at forgecabin confirmed the long term consistency, sites that have maintained quality across years rather than just a recent stretch are sites with serious editorial discipline and this one has clearly been at it for a while.
Came in skeptical and left mostly convinced, that is the highest praise I can offer, and a look at lacecloister pushed me further in the same direction, content that survives a critical first read is rare and worth recognising because most blog posts crumble under any real scrutiny these days when you actually pay attention closely.
Started forming counter examples to test the claims and the post handled most of them implicitly, and a look at hillessence continued that anticipatory style, writers who think two steps ahead of the critical reader save themselves from a lot of follow up work and this writer has clearly internalised that habit consistently.

Reading this in a quiet hour and finding it suited the quiet, and a stop at irisbureau extended the quiet reading mood, content that matches its own optimal reading conditions rather than fighting them is content that has been thoughtfully calibrated and this site reads as having a particular reading mood in mind throughout.
Worth flagging that this approach to the topic is fresh without being contrarian, and a stop at fashionandstylehub 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.
This is something that will need all of our combined efforts to address.
Once I trust a site this much I tend to read everything they publish and that is the trajectory I am on with this one, and a stop at duetdrive confirmed the trajectory, the rare progression from interested reader to comprehensive reader is something only certain sites earn and this one is earning that progression rapidly.
The clarity here is something I really appreciate, especially compared to sites that pile on jargon for no reason, and a look at mintdawn was the same, simple direct sentences that actually deliver information instead of dancing around the point for paragraphs at a time which wastes reader patience.
The post made the topic feel approachable without making it feel trivial, that is a fine balance, and a stop at glowingridgehub maintained the same balance, finding the middle ground between welcoming and serious is genuinely difficult and the writers here have clearly figured out how to consistently hit it well across many different posts.
Decided not to skim despite my usual habit and was rewarded for the discipline, and a stop at forgeoutpost earned the same patient approach, training myself to recognise sites that warrant slower reading is part of being a careful online reader and this site is the kind that helps me practice that skill regularly.
Reading this with a fresh mind in the morning brought out details I might have missed in the afternoon, and a stop at ethicalcuratedgoods earned the same fresh attention, content that rewards being read at full attention rather than at energy lows is content with real density and this site has that density consistently.
A piece that did not waste any of its substance on sales or promotion, and a look at fashionandstylehub continued that pure content focus, sites that resist the urge to monetise every paragraph are increasingly rare and this one has clearly made the editorial choice to keep the writing clean from commercial intrusion which I value highly.
Picked this for my morning read because the topic seemed worth the time, and a look at premiumcuratedmarket confirmed the choice was right, my morning reading slot is precious and giving it to this site felt like a good investment rather than a waste which is a higher endorsement than I usually offer for content.

Came across this through a roundabout path and now it is on my regular rotation, and a stop at forgeoutpost sealed that decision, the open web still produces serendipitous discoveries when you let the citations and references guide you rather than relying purely on algorithmic feeds for new content recommendations always.
Came away with some new perspectives I had not considered before, and after epicestate those ideas felt more complete, the kind of content that stays with you a little while after reading rather than slipping out the moment you switch tabs and move on with your day to whatever comes next.
I am very happy to look your post. Thanks a lot and i am taking a look ahead to touch you.
Worth pointing out the careful word choice in this post, no buzzwords and no jargon, and a look at timberharborfinds continued that disciplined vocabulary, sites that resist the pull of trendy language are sites that will read well in five years and this one is clearly built for that kind of long durability.
Quietly enjoying that I have found a new site to follow for the topic, and a look at duetparish reinforced the small pleasure of the find, the discovery of new high quality sources is one of the more durable pleasures of careful internet reading and this site has been generating that discovery pleasure at multiple points already today.
Excellent execution from start to finish, the post never loses its rhythm and the points stay sharp, and a quick stop at groweverydaynow kept the same level going, consistency like this across a site is the marker of a serious operation rather than a casual side project running on autopilot somewhere else.
WoW decent article. Can I hire you to guest write for my blog? If so send me an email!
you’re in reality a just right webmaster. The web site loading velocity is incredible. It sort of feels that you’re doing any distinctive trick. In addition, The contents are masterpiece. you’ve performed a great process on this topic!
Glad I gave this fifteen minutes rather than the usual three minute skim, and a look at edendune earned the same investment, time spent on quality content is rarely wasted but the reverse is also true and learning which sites deserve which kind of attention is part of being a careful online reader.
