月份运气比较好，摇到了车牌，本来其实应该很早就开始摇的，前面第一次换工作没注意社保断缴了一个月，也是大意失荆州，后面到了 17 年社保满两年了，好像只摇了一次，还是就没摇过，有点忘了，好像是什么原因导致那次也没摇成功，但是后面暂住证就取消了，需要居住证，居住证又要一年及以上的租房合同，并且那会买车以后也不怎么开，住的地方车位还好，但是公司车位一个月要两三千，甚至还是打车上下班比较实惠，所以也没放在心上，后面摇到房以后，也觉得应该准备起来车子，就开始办了居住证，居住证其实还可以用劳动合同，而且办起来也挺快，大概是三四月份开始摇，到 8 月份的某一天收到短信说摇到了，一开始还挺开心，不过心里抱着也不怎么开，也没怎么大放在心上，不过这里有一点就是我把那个照片直接发出去，上面有着我的身份证号，被 LD 说了一顿，以后也应该小心点，但是后面不知道是哪里看了下，说杭州上牌已经需要国六标准的车了，瞬间感觉是空欢喜了，可是有同事说是可以的，我就又打了官方的电话，结果说可以的，要先转籍，然后再做上牌。</p><p>转籍其实是很方便的，在交警 12123 App 上申请就行了，在转籍以后，需要去实地验车，验车的话，在支付宝-杭州交警生活号里进行预约，找就近的车管所就好，需要准备一些东西，首先是行驶证，机动车登记证书，身份证，居住证，还有车上需要准备的东西是要有三脚架和反光背心，反光背心是最近几个月开始要的，问过之前去验车的只需要三脚架就好了，预约好了的话建议是赶上班时间越早越好，不然过去排队时间要很久，而且人多了以后会很乱，各种插队，而且有很多都是汽车销售，一个销售带着一堆车，我们附近那个进去的小路没一会就堵满车，进去需要先排队，然后扫码，接着交资料，这两个都排着队，如果去晚了就要排很久的队，交完资料才是排队等验车，验车就是打开引擎盖，有人会帮忙拓印发动机车架号，然后验车的会各种检查一下，车里面，还有后备箱，建议车内整理干净点，后备箱不要放杂物，检验完了之后，需要把三脚架跟反光背心放在后备箱盖子上，人在旁边拍个照，然后需要把车牌遮住后再拍个车子的照片，再之后就是去把车牌卸了，这个多吐槽下，那边应该是本来那边师傅帮忙卸车牌，结果他就说是教我们拆，虽然也不算难，但是不排除师傅有在偷懒，完了之后就是把旧车牌交回去，然后需要在手机上（警察叔叔 App）提交各种资料，包括身份证，行驶证，机动车登记证书，提交了之后就等寄车牌过来了。</p><p>这里面缺失的一个环节就是选号了，选号杭州有两个方式，一种就是根据交管局定期发布的选号号段，可以自定义拼 20 个号，在手机上的交警 12123 App 上可以三个一组的形式提交，如果有没被选走的，就可以预选到这个了，但是这种就是也需要有一定策略，最新出的号段能选中的概率大一点，然后数字全是 8，6 这种的肯定会一早就被选走，然后如果跟我一样可以提前选下尾号，因为尾号数字影响限号，我比较有可能周五回家，所以得避开 5，0 的，第二种就是 50 选一跟以前新车选号一样，就不介绍了。第一种选中了以后可以在前面交还旧车牌的时候填上等着寄过来了，因为我是第一种选中的，第二种也可以在手机上选，也在可以在交还车牌的时候现场选。</p><p>总体过程其实是 LD 在各种查资料跟帮我跑来跑去，要不是 LD，估计在交管局那边我就懵逼了，各种插队，而且车子开着车子，也不能随便跑，所以建议办这个的时候有个人一起比较好。</p></div><footer class="post-footer"><div class="post-eof"></div></footer></article></div><div class="post-block"><article itemscope

itemprop="articleBody"><p>很久之前就听说过这个框架，不过之前有点跟消息队列混起来，这个也是种队列，但不是跟 rocketmq，nsq 那种一样的，而是在进程内部提供队列服务的，偏向于取代<code>ArrayBlockingQueue</code>，因为这个阻塞队列是使用了锁来控制阻塞，关于并发其实有一些通用的最佳实践，就是用锁，即使是 JDK 提供的锁，也是比较耗资源的，当然这是跟不加锁的对比，同样是锁，JDK 的实现还是性能比较优秀的。常见的阻塞队列中例如 <code>ArrayBlockingQueue</code> 和 <code>LinkedBlockingQueue</code> 都有锁的身影的存在，区别在于 <code>ArrayBlockingQueue</code> 是一把锁，后者是两把锁，不过重点不在几把锁，这里其实是两个问题，一个是所谓的 <code>lock free</code>, 对于一个单生产者的 <code>disruptor</code> 来说，因为写入是只有一个线程的，是可以不用加锁，多生产者的时候使用的是 cas 来获取对应的写入坑位，另一个是解决“伪共享”问题，后面可以详细点分析，先介绍下使用<br>首先是数据源</p><pre
