<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"><span style="font-size: 10.5pt; font-family: '宋体';">从专科毕业以来，工作已有三年有余。转眼间，我将要离开长沙，前往杭州开始一段新的人生旅程。心情难免相当复杂，在这期间，发生了很多事情。随之，自己也改变了很多。</span></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"><span style="font-size: 10.5pt; font-family: '宋体';">这三年，在长沙博赛软件公司任职。这里，员工待遇不错，工作相对轻松。更重要的是，同事之间关系简单并且和睦，这样的公司确实不多。</span></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"><span style="font-size: 10.5pt; font-family: '宋体';">事实上，我几乎没有向朋友提起过，在这期间，我还在另外一家计算机培训公司做培训讲师，工作了差不多两年。有时，一天工作超过了<font>16</font><font>个小时，从早上</font><font>6</font><font>点到晚上</font><font>10</font><font>点，觉得很累。说出来可能没人不相信，当时我还在长沙大学读本科。时常受到老师的责骂，无论多么难听，我都能忍受。当然，不会去说这些知识对我没有价值或者已经知晓。</font></span></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"><span style="font-size: 10.5pt; font-family: '宋体';">纸是包不住火，有些老师和同学知道我的情况。我只能在学校里面尽量隐瞒，因为一旦提到薪酬问题上，每个同学的反应会不同，更不要说老师。在学校里面从来不会炫耀，甚至不提到技术。完全没有必要。</span></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"><span style="font-size: 10.5pt; font-family: '宋体';">能够的事情告诉你，你会知道的，反之亦然。正如这里，我在告诉大家发生了什么，而不是为了炫耀（炫耀是种心态的问题）。同时，也是向老师和同学们道歉，我有我的苦衷。</span></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"><span style="font-size: 10.5pt; font-family: '宋体';">我的坚持，让我学业和事业得到平衡，尽管人比较累，但是我从来没有抱怨过。我记得有句这样的话，&#8220;年轻的时候不努力，怎么在<font>40</font><font>岁之后享受事业的成果&#8221;。这几年，尤为明显，整个社会都很浮躁。很多年轻人老抱怨。当然，可以抱怨大是大非的问题，但是总是抱怨不公平，而反思自己是不客观的。我的观点是，这个世界永远是灰色的，也没有绝对的公平，不要浪费时间去讨论它，因为它会自动变化的，每个阶段会呈现不同的状态。当不能改变的时候，只能适应它。抓紧时间，做好自己就很好了。</font></span></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"><span style="font-size: 10.5pt; font-family: '宋体';">兴趣和激情是够支持我高强度工作的动力，我一直认为除了谋生以外，感兴趣是最关键的。个人观点，事业就是做自己在做想做的事情，职业则是在做谋生的事情。事业会带来财富和名望。</span></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"><span style="font-size: 10.5pt; font-family: '宋体';">事业没有高低贵贱，但是适合与否只有自己知道。这就是我为什么选择离开的原因。虽然，马上要离开长沙博赛了，但是心中仍然有点不舍，同时我心存着感激，感谢那些曾经帮助过我的人。当然，两家公司的离开，有无奈的地方，也有惊人相似之处。对此，我不想说什么。如果我的离开，能够给其他人带来安稳，那么也不失为好事一件。同事一场，希望大家能够真正地好好工作，给自己和家庭带来安全感。</span></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"><span style="font-size: 10.5pt; font-family: '宋体';">人生不能用简单地套用&#8220;设计图纸&#8221;，而是随着实际情况而制定，不至于计划赶不上变化。工作并不是我生活的全部。我不是那种天天喊事业的人，也是一个凡人。也会接触到柴米油盐，我也想有一个幸福家庭。自然面对房子问题，这是年轻人心中一块大石，尤其是像我这种父母没有积蓄的人。说良心话，我住了父母的房子，这也是一种&#8220;啃老&#8221;，只是程度问题。通过客观分析，在短期内得出房价不会大降。终于决定在<font>4</font><font>月份买房。我一直很幸运，通过我三年的积累和平时省吃俭用，凑齐了一套房子的首付款。不巧的是，国家出台楼市调控政策，其结果是把我所有的积蓄消耗尽了。选择房贷的年限是一门学问，不但要结合自己的经济实力，还要分析未来工资趋势，选择一种月供压力较小的方式。这样，清除了一大后顾之忧。至少，无论是否事业成功，至少我有了退路。</font></span></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"><span style="font-size: 10.5pt; font-family: '宋体';">买房之后，为谋求更高的职业目标，接下来开始找工作。参加几家大公司的面试，这些公司社会招聘流程中，需要候选人经过<font>4</font><font>轮以上的面试。有时候，不得不相信命运，本人均在最后一面&#8220;神秘地&#8221;地被刷下来了。面试过程感觉良好，还得到了面试官肯定。也许是否极泰来，</font><font>9</font><font>月份，受邀淘宝网和支付宝（皆为阿里巴巴集团公司下的两家子公司）面试通知，终于在这次得到了回报。两家公司面试都通过了。当时脑中顿时想起《当幸福来敲门》那部电影。从失利到成功，我的心里素质变得更好了。相比我其他一些遭遇，也算不了什么的。感谢那些在我失利的时候，给我鼓励和帮助的朋友，尤其要感谢我的女朋友。</font></span></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"><span style="font-size: 10.5pt; font-family: '宋体';">鱼和熊掌不能兼得，结合自己的实际情况和职业房展，接受了淘宝公司的<font>Offer</font><font>，在此，对于支付宝公司珍重人才表示感谢，特别是那个美女</font><font>HR</font><font>。最重要的是，认识了几个朋友。接下来，我希望在淘宝公司，通过自己的努力，事业上能够得到长远的发展。</font></span></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"><span style="font-size: 10.5pt; font-family: '宋体';">人生的道路上总会面临抉择，有时候是主动的，有时却是被动的。不管怎样，学会怎么选择比学会如何努力要重要很多。正确的方向需要不断地识别和选择。只有在正确的方向上，那么不会感到迷茫和无助。强者运命，弱者命运。人生不少事情需要自己经营，无论是事业，还是爱情。</span></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"></p>
<p class="p0" style="text-indent: 21pt; margin-bottom: 0pt; margin-top: 0pt; text-align: left;"><span style="font-size: 10.5pt; font-family: '宋体';">最后，提前向亲爱的博赛同事道别，祝大家能够事业有成，幸福安康。</span></p>

<span style="font-family: 'DejaVu Sans'; font-size: small;">大学，大家都来学。对于大学而言，笔者和很多人一样，还是挺期待的。在这期间，有两个词汇让我难以忘记，一个是&#8220;冯诺依曼体系结构&#8221;，一个是&#8220;摩尔定律&#8221;。前者确定了目前计算机体系结构，后者预言了计算机芯片（集成电路）的更新周期。</span>

记得老师是这么描述摩尔定律</span>
<span style="font-family: 'Times New Roman',serif; font-size: small;">-&#8220;</span>
<span style="font-family: 'DejaVu Sans'; font-size: small;">计算机芯片集成电路数量，每</span>
<span style="font-family: 'Times New Roman',serif; font-size: small;">18</span>
<span style="font-family: 'DejaVu Sans'; font-size: small;">个月翻一翻&#8221;。听过之后，我顿时感到神奇。神的地方是，不能理解为什么电脑电脑更新这么快。奇的地方，计算机芯片既然物质，那么肯定有极限，芯片数量级不可能会成数学规律增长。因此，我对这个预言一直抱有怀疑的态度。</span><br />

<p style="margin-bottom: 0in;" align="LEFT">
<span style="font-family: 'DejaVu Sans'; font-size: small;"><span style="font-family: 'Times New Roman',serif;">&nbsp;&nbsp; &nbsp;</span>
针对这个理论，世界芯片级巨头</span>
<span style="font-family: 'Times New Roman',serif; font-size: small;">Intel</span>
<span style="font-family: 'DejaVu Sans'; font-size: small;">相当地认可，毕竟摩尔其人也是</span>
<span style="font-family: 'Times New Roman',serif; font-size: small;">Intel</span>
<span style="font-family: 'DejaVu Sans'; font-size: small;">创建人之一。因此，</span>
<span style="font-family: 'Times New Roman',serif; font-size: small;">Intel</span>
<span style="font-family: 'DejaVu Sans'; font-size: small;">芯片数量的规律非常贴近摩尔定律。</span>

在很大程度上，硬件执行速度决定了计算机的运行速度。那也就说，摩尔定律也影响着系统运行效率。众所周知，操作系统支持并发执行，不过在单处理器，宏观上是并行
，但微观上是串行。在这种情况下，并行实现则是由</span>
<span style="font-family: 'Times New Roman',serif; font-size: small;">CPU</span>
<span style="font-family: 'DejaVu Sans'; font-size: small;">轮询的方式来执行任务，在用户感知下，是不会觉得延迟的。如果</span>
<span style="font-family: 'Times New Roman',serif; font-size: small;">CPU</span>
<span style="font-family: 'DejaVu Sans'; font-size: small;">处理的速度越快，因此，</span>
<span style="font-family: 'Times New Roman',serif; font-size: small;">CPU</span>
<span style="font-family: 'DejaVu Sans'; font-size: small;">在任务之间切换的时间就越短，用户更加不会察觉。</span>

<span style="font-family: 'DejaVu Sans'; font-size: small;"><span style="font-family: 'Times New Roman',serif;">&nbsp;&nbsp; &nbsp;</span>
摩尔定律，可谓是成也</span>
<span style="font-family: 'Times New Roman',serif; font-size: small;">Intel</span>
<span style="font-family: 'DejaVu Sans'; font-size: small;">，败也</span>
<span style="font-family: 'Times New Roman',serif; font-size: small;">Intel</span>
<span style="font-family: 'DejaVu Sans'; font-size: small;">。由于开发成本和物理极限等原因，单处理器遇到了瓶颈，
摩尔定律也宣告失效。新的时代来临</span>

<span style="font-family: 'DejaVu Sans'; font-size: small;">笔者却认为摩尔定律就是一个&#8220;大忽悠&#8221;，无论是物理限制，还是计算机体系和脑力的局限性。正所谓英雄所见略同。不久前，微软创始人</span>

<span style="font-family: 'DejaVu Sans'; font-size: small;">盖茨兄弟，也赞同<a href="http://www.linuxpk.com/viewnews-23505.html" target="_blank">这种观点</a>
。同时，</span>
<span style="font-family: 'Times New Roman',serif; font-size: small;">Intel</span>
<span style="font-family: 'DejaVu Sans'; font-size: small;">这些公司，为了弥补技术革命上面的憋足，把这种摩尔意识强如植入了民众的大脑，这就不难解释，在</span>
<span style="font-family: 'Times New Roman',serif; font-size: small;">2005</span>
