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)

    The depth of coverage felt about right for the format, neither shallow nor overwhelming, and a look at focusdirector kept that calibration going, getting the depth right for blog format is genuinely difficult because too shallow loses experts and too deep loses beginners but this site nailed it nicely which I really do appreciate.

    Probably worth setting aside a longer block to read more carefully than I can right now, and a stop at capitalbondway confirmed the longer block plan, the impulse to schedule dedicated time for a sites archive is itself a measure of trust and this site has earned that scheduling impulse from me clearly today actually.

    Felt the writer did the homework before publishing, the references hold up, and a look at forwardenergyengine continued that documented care, content with traceable claims rather than vague assertions is the kind I trust and the lack of bald assertion in this post is one of its quietly impressive qualities for me.

    Bookmark added with a small mental note that this is a site to keep, and a look at forwardmomentum reinforced the keep status, the verb keep rather than visit captures something about how I think about this kind of site and it is a higher tier of relationship than I have with most places online today.

    Left me wanting to read more rather than feeling burned out, that is a good sign, and a look at vitalbonding confirmed there is plenty more here to explore, the kind of writing that builds appetite rather than killing it which is a rare quality on the modern open internet today across most categories of content.

    Мы работаем круглосуточно, бригада выезжает по любому адресу в Москве в течение 30-60 минут после оформления заявки. Врач-нарколог приедет на специализированном транспорте, оснащенном необходимым оборудованием и медикаментами для проведения интенсивной терапии в домашних условиях. С учетом состояния пациента врач определяет, можно ли поставить алкогольную капельницу на дому или лучше откапать от алкоголя в стационаре. При выраженном абстинентном синдроме, спутанности сознания, серьезном риске алкогольного психоза или наличии тяжелой сердечной недостаточности рекомендована срочная госпитализация. Анонимность обращения и конфиденциальность данных — это основа нашей работы, информация о лечении не передается третьим лицам и не ставит пациента на учет. Многие обращаются к нам за помощью, потому что убедились: здесь действительно можно избавиться от алкоголизма без огласки. Заказать выезд нарколога можно по телефону или через форму на сайте — мы перезвоним вам в течение получаса, чтобы отправить бригаду.

    A piece that built up gradually rather than front loading its main points, and a look at progressigniter maintained the same gradual structure, content that trusts the reader to reach conclusions through accumulating reasoning is more persuasive than content that announces conclusions and then defends them and this site uses the persuasive approach.

    Looking through other posts here the consistency is what makes the site valuable rather than any single piece, and a stop at intentionalclarity extended that consistency observation, sites whose value lies in the ongoing pattern rather than in standout posts are sites I trust more deeply and this one has clearly built that kind of trust.

    Thanks for treating the topic with the seriousness it deserves without becoming pompous about it, and a stop at lighthousefinds continued that balanced treatment, the gap between earnest and self serious is huge and writers who can stay on the right side of it earn my respect when I find them online today.

    A piece that brought a sense of order to a topic I had been finding chaotic, and a look at growthengine continued that organising effect, content that imposes useful structure on messy subjects is doing genuine intellectual work and this site is providing that organisational function across multiple posts I have read recently here.

    A piece that ended with a clean landing rather than fading out, and a look at cornerstoneunity maintained the same crisp conclusions, endings that resolve rather than dissolve are a sign of careful structural thinking and this site has clearly invested in how its pieces conclude rather than letting them simply run out of energy.

    Вывод из запоя — это только первый шаг в лечении алкогольной зависимости. Без последующей терапии риск рецидива очень высок. Наш наркологический центр предлагает полный курс лечения алкоголизма, включая кодирование и психотерапию. Кодирование на дому проводится различными методами: уколом (Торпедо, Эспераль, Налтрексон, Аквилонг), медикаментозным вшиванием (дисульфирам, Вивитрол), гипнозом по Довженко, а также двойным блоком. Каждый метод подбирается врачом индивидуально, с согласия пациента и при отсутствии противопоказаний. Опытный нарколог объяснит, какая кодировка подойдёт именно вам, учитывая стаж и форму зависимости.
