<p>Ten engineering values for writing simple, readable, maintainable Go code. Presented at GopherCon Israel 2020.</p>
<p><strong>Each package fulfils a single purpose</strong><br>    A well designed Go package provides a single idea, a set of related behaviours. A good Go package starts by choosing a good name. Think of your package’s name as an elevator pitch to describe what it provides, using just one word.</p>
<p><strong>Handle errors explicitly</strong><br>    Robust programs are composed from pieces that handle the failure cases before they pat themselves on the back. The verbosity of if err != nil { return err } is outweighed by the value of deliberately handling each failure condition at the point at which they occur. Panic and recover are not exceptions, they aren’t intended to be used that way.</p>
<p><strong>Return early rather than nesting deeply</strong><br>    Every time you indent you add another precondition to the programmer’s stack consuming one of the 7 ±2 slots in their short term memory. Avoid control flow that requires deep indentation. Rather than nesting deeply, keep the success path to the left using guard clauses.</p>
<p><strong>Leave concurrency to the caller</strong><br>    Let the caller choose if they want to run your library or function asynchronously, don’t force it on them. If your library uses concurrency it should do so transparently.</p>
<p><strong>Before you launch a goroutine, know when it will stop</strong><br>    Goroutines own resources; locks, variables, memory, etc. The sure fire way to free those resources is to stop the owning goroutine.</p>
<p><strong>Avoid package level state</strong><br>    Seek to be explicit, reduce coupling, and spooky action at a distance by providing the dependencies a type needs as fields on that type rather than using package variables.</p>
<p><strong>Simplicity matters</strong><br>    Simplicity is not a synonym for unsophisticated. Simple doesn’t mean crude, it means readable and maintainable. When it is possible to choose, defer to the simpler solution.</p>
<p><strong>Write tests to lock in the behaviour of your package’s API</strong><br>    Test first or test later, if you shoot for 100% test coverage or are happy with less, regardless your package’s API is your contract with its users. Tests are the guarantees that those contracts are written in. Make sure you test for the behaviour that users can observe and rely on.</p>
<p><strong>If you think it’s slow, first prove it with a benchmark</strong><br>    So many crimes against maintainability are committed in the name of performance. Optimisation tears down abstractions, exposes internals, and couples tightly. If you’re choosing to shoulder that cost, ensure it is done for good reason.</p>
<p><strong>Moderation is a virtue</strong><br>    Use goroutines, channels, locks, interfaces, embedding, in moderation.<br>Maintainability counts</p>
<p>知名 Go 语言贡献者与布道师 Dave Cheney 发表了名为《The Zen of Go》<br>编写简单、可读、可维护的 Go 代码的十个工程要点。</p>
<p><strong>每个包实现单一目标</strong><br>设计良好的 Go 软件包提供一个单一的思路，以及一系列相关的行为。一个好的 Go 软件包首先需要选择一个好名字，使用电梯法则（30 秒内向客户讲清楚一个方案），仅用一个词来思考你的软件包要提供什么功能。</p>
<p><strong>明确处理错误</strong><br>健壮的程序其实是由处理故障案例的片段组成的，并且需要在故障出现之前处理好。冗余的if err != nil { return err }比出了故障再一个个去处理更有价值。panic 和 recover 也一样。</p>
<p><strong>尽早 return，不要深陷</strong><br>每次缩进时都会在程序员的堆栈中添加另一个先决条件，这会占用他们短期内存中的 7±2 个片段。避免需要深层缩进的控制流。与其深入嵌套，不如使用守卫子句将成功路径保持在左侧。</p>
<p><strong>并发权留给调用者</strong><br>让调用者选择是否要异步运行你的库或函数，不要强制他们使用异步。</p>
<p><strong>在启动 goroutine 之前，要知道它什么时候会停止</strong><br>goroutines 拥有资源、锁、变量与内存等，释放这些资源的可靠方法是停止 goroutine。</p>
<p><strong>避免包级别的状态</strong><br>要完成明确和减少耦合的操作，需要通过提供类型需要的依赖项作为该类型上的字段，而不是使用包变量。</p>
<p><strong>简单性很重要</strong><br>简单性不是老练的代名词。简单并不意味着粗糙，它意味着可读性和可维护性。如果可以选择，请遵循较简单的解决方案。</p>
<p><strong>编写测试以确认包 API 的行为</strong><br>软件包的 API 是与使用者的一份合约，不管先后，不管多少，一定要进行测试。测试是确定合约的保证。要确保测试使用者可以观察和依赖的行为。</p>
<p><strong>如果你认为速度缓慢，先通过基准测试进行验证</strong><br>以性能之名会犯下许多危害可维护性的罪行。优化会破坏抽象、暴露内部和紧密耦合。如果要付出这样的代价，请确保有充分理由这样做。</p>
<p><strong>节制是一种美德</strong><br>适度使用 goroutine、通道、锁、接口与嵌套。</p>

<p>LEONARDO所扮演的男主角，曾经是一名参加过2战的战士，他曾经亲眼目睹过纳粹集中营中，对于犹太人的种种暴行，从他的回忆中可以看出来，并且他也目睹了纳粹集中营头领由于笨拙的自杀方式，导致在开枪自杀后并没有立即死去，电影中男主角看着濒死的纳粹头领在用尽一切办法想再次拿枪自刎时，选择了把手枪用脚挪开而让纳粹首领在自刎一个小时之后才死亡，并且当有一个纳粹俘虏由于紧张想要逃跑的时候，他所在的队伍毫不犹豫的将那些纳粹俘虏尽数击毙，他所经历的一切让他患上了所谓的战后精神综合症，这种症状表现为焦虑，不安，酗酒，等等，具体的可以自己去看看其他资料。</p>
<p>再继续回到电影男主角其实是这个精神病院里患病最深的一个患者，因为他有着很明显的双重人格，也就是所谓的分裂的人格，这个人格分为两个部分，一个部分是Andrew Laeddis，就是防火烧了他家，熏死他妻子和孩子的那个人；另外一个是Teddy，也就是他幻想中的那个执法官。故事的起因是，他战后回到家乡，和自己的妻子结婚，并且有了几个孩子，而他由于有着强烈的战后精神上的表现，使得自己对于他的妻子，孩子虽然很在于，但是却疏于关心爱护，这直接使他们的婚姻生活并不如意，导致了他的妻子在长期服用药物的情况下精神失常，终于在某一日，她的妻子精神病爆发，亲手溺死了自己的几个孩子，而当他回家目睹这一幕的时候，由于过分的悲伤难过，在精神极度紧张，压力很大的情况下用手枪结束了自己妻子的命运，并防火烧了自己的房子。这一点从电影中就可以看出来，有一幕是他搂着自己的妻子，在满是烟尘的房间里，他妻子的腹部在流血，这足以说明他的妻子并不是被烟熏死，或者被火烧死，而是被他枪杀。</p>
<p>在这种精神状况下，主角出现了所谓的人格分裂，并且极度暴力。他的意识分为了两个部分，上文已经提过。他不断的站在自己善良的一面而寻找自己凶残的另一面，这样的精神状态使他自己很难分辨出来，到底什么是真相，自己所寻找的真相是什么，因为他活在了自己思维所创造出来的世界里。原因很简单，他无法接受自己的妻子死于自己的枪下。接着，他应该是被送往了精神病院接受治疗。我们知道，在80年代之前，治疗这类精神病的一般方式是利用药物和外科手术。药物一般无非是镇静剂之类，而外科手术则是前脑叶蛋白切除，这中外科手术一般目的在于让人失去记忆，失去直觉等等，简单来说就是成为一个傻子，没有痛苦，没有高兴，开心等一系列的感情意识（看过影片《飞跃疯人院》的朋友应该能了解，只是后来这种手术由于缺乏对于人的基本尊重而被废除了）。影片里所有的安委会（大概就这个意思了）成员一致认为应该让男主角进行这种手术，但是他的这家精神病医院的院长以及他的主治医师，也就是电影中男主角自己想象中的助手，来自于西雅图的那人，都极力反对，因为他们在尝试用另外一种办法治愈这种疾病，也就是角色带入法，role-play，也就是常说的角色扮演，他们希望创造一个男主角所臆想出的空间，时间，让男主角在这段幻想中逐渐情形，走出幻想，从而真正的意识到自己，于是，影片的第一幕开始了，也就是所谓的角色扮演治疗方式正式启动。</p>
<p>男主角的幻想中，他性格中邪恶的那一面的具体指代物—Andrew Laeddis，去到了在禁闭岛上的那家医院，而他又给自己找了一个很好的理由，就是溺死自己孩子的那个母亲从医院里跑了，这样，他人格中善良的那一个人，Teddy，联邦执法官，便有了去禁闭岛调查的理由。于是，他带着幻想中的助手chuck，其实就是他的主治医师（Lester Sheehm），一起来到了禁闭岛，而从他在船上时，晕船，不喝酒，就可以看出，他的潜意识里非常的惧怕水，因为他的孩子正是被自己的妻子溺死的，并且他不喝酒，因为正是由于酗酒导致的家庭生活不如意，这点从他一到家先喝酒就能看出来。来到小岛之后，小岛上的狱警们如林大敌，而男主角却对这点嗤之以鼻，因为他认为联邦法官的到来还不至于如此，其实，狱警们这正防范的其实不是正是主角本人，因为他本身是一个退役的战士，联邦调查局的侦探，经历过人格分裂之后已经成为一个极端暴力和危险的人物。而进入医院大门之前，有一个缴枪的情节，可以看出，主角卸枪的熟练程度和他的助手是截然不同的，因为那人并不是什么可配枪的执法官，而是一名医生而已，而这个所谓的穿帮让他的“助手”用自己只是文职人员所掩饰过去了。</p>
<p>当男主角在医院内进行自己臆想中的所谓“调查”的时候，他发现，那个溺死自己孩子的母亲“瑞秋”不见了，而在床底下留了一张纸条，上面写的是，根据第四条规则，谁是第67号病人。其实这正是男主角在自己潜意识里追寻的目标，到底第67号病人是谁。其实答案很简单，正是他自己本人，这一点在后来他的“助手”在悬崖边给他一张入院档案的纸上可以看出来，他的医生希望他自己能够清醒的意识到这一点，只是男主角自己并不承认罢了。关于第四条规则，后来电影中在灯塔那里，医院的那个光头院长也给他讲述了，其实那些名字都是从他名字和他妻子的名字中重新排列字母组合而成的。电影中失踪的瑞秋，其实就是照顾他的护士，后来从他在床上躺着，而那个护士则在一边端着药盘可以看出来。</p>
<p>之后男主角在他的世界里进行了一系列的“调查”，首先是那个用玻璃把给自己父亲看病的护士脸划破的人开始，他问那个病人是否认Andrew Laeddis的时候，那名病人显得非常害怕，紧张，不敢说话，其实那个病人是认识男主角的，也深知他的暴力程度，可是男主角却知道对方不能忍受那种用尖的物体摩擦东西的声音，却故意用笔在纸上摩擦以发出声响来激怒，恐吓对方，由此可见男主角的恐怖程度，这样的结果使得后者在极大的愤怒和恐惧之下说出了那个把自己的孩子溺死的人，应该受到极刑，甚至应该被毒气毒死，而这句话深深的刺激了男主角的潜意识，应该说也是一个让他治愈的一个开始吧。</p>
<p>而后他“审问”的是一个典型的大妈，那个大妈可能是精神病院里，除了医生护士警卫之外精神最正常的一个人了，她只是不堪忍受家庭暴力而亲手结束了自己丈夫的姓名。她告诉男主角，那个所谓的瑞秋把医院里的每一个人病人都想象成了自己的邻居，赋予他们社会的角色，这正是想让男主句意识到其实他本人就是如此，但是当男主角把Andrew Laeddis是谁这个同样的问题抛给她时，善良的大妈知道他已经没救了，估计要被进行那种切除脑叶的外科手术时，支走了他的主治医师，在纸上给他写了一个字母“RUN”，意思让他赶紧从医院里跑出去，因为不久之后他会变成一个傻子，什么都不知道。</p>
<p>再后来影片还有一个情节，男主角要求医院开一个什么会，讨论关于走失的瑞秋以及她本人因为放假而回家的主治医师的什么事，结果当他紧张的进来时，发现大家似乎却并没有太在意，他很生气，询问这是为什么，而大家却都觉得可笑，现在想来确实如此，一帮正常人在讨论一件没有的事，没有走失的瑞秋，而所谓瑞秋的医生其实就是他的助手，而男主角却在那里煞有介事，是一件多么可笑的事啊。</p>
<p>剧情接着发展。男主角让医院的警卫们去海边寻找瑞秋，结果那帮狱警为了配合他不得不去寻找，当他提及为什么不去灯塔那边的山上也搜寻时，警卫们的回答是那里的路不好走，而且马上要来暴风雨了，改日再说。而之后的电影给我们阐述的确实，他仅仅一个人，在没有借助任何登山工具的情况下就可以轻而易举的爬下岩石，并且还找到了一个因为不满医院对病人实施外科手术而逃跑的女医生的时候，就可以知道，去那里根本不费什么力气，只是警卫们认为他所幻想的一切都是假的，根本就没有瑞秋，去那里能找到什么呢。</p>
<p>之后，“瑞秋”找到了，她其实是一名护士，在和男主角的谈话中，不断的提及溺死的孩子，亲手杀死自己的配偶，并不断的询问他“你是谁”，就是想通过这些刺激让主角认识自己，可是依旧，没有成功。之后，男主角的医生，也就是他的助手，只有通过另外一个手段，就是让他进入他思想中所谓的“C区”，他们安排了一个假停电的情节，让C区如入无人之境，而让他相信医院能够停电的情节在之前他要求医院开集体大会的时候，那些人已经透露给他了。而后，他和他的医生来到了所谓的C区，C区是一个看管有着重度精神病患，而且极其危险的病人的地方。来到C区，医生们首先安排了一个病人，对他进行心里暗示，那个病人告诉他，他不愿意离开这里是因为他已经在这里太久，而不愿意去接受外部世界，他不知道什么是氢弹等等。。。目的就在于让他意识到自己一直生活在自己的世界里，从而与世隔绝，和上面的情况一样，没有效果。后来，医生借故离开他，让他自己去找那个叫George Noyce，就是他所说的大学生，试想一下，如果不是George Noyce自己告诉男主角自己放火什么的事，他又怎么能从外界得知呢。后来男主角轻易的就找到了后者，其实原因很简单，因为男主角也是生活在C区的一个患者，并且是最重度，最危险的那一个。男主角和他的谈话也是围绕这Andrew Laeddis是谁而展开的，后者一直在暗示他其实那人就是他自己，告诉他其实这一切只是一个针对他的游戏，他只不过是迷宫里的白鼠，除非他意识到事情的真相，真正放下自己妻子溺死孩子，他杀害妻子的这个事，否则他将永远离不开这里，也就是永远无法从自己的世界里走出来。他之后问及Andrew Laeddis到底是谁的时候，后者也似乎指明了就是他，而且他脸上的那些伤也是拜主角所赐，因为后者曾当面指明过他就是自己所苦苦追寻的Andrew Laeddis，结果是主角不信，反而给他了一顿痛打。这一招失败以后，后者只能把最后的一切线索指向了主角心目中的“灯塔”。</p>
<p>尾声。主角在灯塔里，男主角见到了他的“助手”和院长，二人最大程度的向他讲明了事实的真相，包括那些字母的组合，那些照片的来历以及他的真实经历。主角在这种情况下，变得怒不可亵，甚至准备开枪将二人打死，可是却发现，其实他的那把枪不过是一个玩具而已。。。。。。还有一个细节，就是所谓的那种非常BT的手术室，却只有区区一个警卫，并且警卫在缴械之后还问他“你该不会杀了我吧”。</p>
<p>结局。一觉醒来，在自己所幻想的世界里走了一遭的男主角，终于清醒的认识到了自己究竟是谁，事实的真相到底是什么，而我们也从他的口中听到了自己对于真实世界的认知。这一切的一切仿佛已经说明他已经在这种治疗的方法下完全康复了。可是，结局的意外却将这个影片推向了高潮。在第二天的清晨，他的主治医师，也就是他的助手，坐在他的身旁，却意外的听见主角仍旧叫他查克，仍旧跟他讨论计划逃离这个岛的事，在医生和院长眼神的交汇中，可以看出，医生认为主角的意识还是不清醒的，他们的计划应该是失败了。这个所谓的计划，院长说过，就是于病人进行沟通，试着去听他们说话，试着于他们进行交流，从而帮助他们走出自己的阴影，而不必接受外科手术。可是主角的这几句话，让他们彻底失望，从而不得不接受让他进行外科手术的方案。而后，男主角站起来，慢慢的走向将要带走他的几个警卫和医院工作人员的时候，说了一句意味深长的话，“Which would be worse?To live as a monster…or to die as a good man.”“哪一样更差些呢？是像个怪物一样活着，还是像个人一样死去”。当他的医生听见这句话的时候，其实知道了主角的病已经完全康复了，只是，男主角自己接受不了这样的现实，他宁愿生活在自己的世界里，宁愿在自己的世界里死亡也不愿意背负这那样沉重的思想负担而生活着。因此他选择进行外科手术，去除掉自己的记忆，思维，感官，意识，因为康复前的他不愿意去面对，而康复之后的他却无法面对，而他的医生，则是默默的，尊重了他的选择。</p>
<p>全剧终。 其实，影片的一些思想，观点是很发人深思的。当主角最清醒的时候，其实也正是他自己最悲伤的时候，自己的妻子杀死了自己的孩子，进而自己又亲手结束了爱妻的生命，这样的结局，需要去承担，会对人造成多大的心里伤害呢。到底是选择在外界面对着这样的悲剧，痛苦的或者，还是在禁闭岛里，麻痹着自己，失去自我的活着。到底是做一个杀人凶手Andrew eddis，还是做一个善良的联邦法官Teddy，我想，主角做出了自己的选择。有的时候，人能够忘记过去，忘记一些很难忘记的事情，其实是一种幸福，既然如此，为什么人还要回到悲剧的原点而重新开始呢！ </p>

        <p>夏洛特（英格丽·褒曼）是某乐团杰出的钢琴演奏员，她的女儿伊娃（丽芙·乌尔曼）是一名在农村社区工作的牧师的妻子，两人之间有一道深深的感情鸿沟，七年来不曾有过任何交流。在得知夏洛特的第二任丈夫去世后，伊娃写信邀请夏洛特来同住，两人都试着友好相处，却不免又将往事重提。伊娃怨恨夏洛特没在她童年时给予她足够的爱护，只把重心放在自己的事业上，疏远了自己和另一个有高度残疾、只能发不清晰的音来与人交流的女儿海琳（莱娜·尼曼）。而夏洛特因为海琳与伊娃住在一起，加上丈夫的去世给自己造成很大打击，也是心情闷闷紧锁眉头。</p>
<p>以下转自豆瓣。<a href="https://movie.douban.com/review/1051780/" target="_blank" rel="noopener">https://movie.douban.com/review/1051780/</a></p>
<p>　　夏洛特 无爱的动机<br>　　她是第一主题，她永远是第一，带着高贵的光环。当她穿着一袭鲜红长袍出现在女儿女媳面前时，就让人不自禁的有种压迫感。刚到女儿家，她就开始迫不及待地叙说她在医院照料病危情人的经历。与其说她在抒发自己对死者的悲痛，毋宁说她在讲叙自己如何值得同情，需要安抚的遭遇。她所有倾诉的落脚点都在自己身上，所有情感的指向都在自己身上，她对自己是这样的充满了激情，以至于她的目光不可能停留在别人身上，她情感的空间不可能扩展一点点，哪怕是对她的丈夫，女儿。对于别人的不幸，苦痛，她本能地抗拒。当小女儿告诉她姐姐被接来了时，她脸上立即阴云密布，在无可奈何地去探望这个有病的女儿时，片中经常使用的近镜头清晰地凸现出她对这个女儿本能的厌恶。她是一个无爱的人，但她却需要爱，需要很多很多的爱，需要身边的每一个人都来爱她，关心她，膜拜她。她也知道，爱是相互的，因此她善于表演，伪装，表演对别人的热情，伪装对别人的爱，甚至有时候她自己也开始相信自己是懂得爱的，但在她连亲人的形象也记不清时，她终于发现，她自以为爱别人爱得最强烈时，只是她需要别人的爱需要得最强烈时。她不懂得爱。她是强大的，因无爱的彻底而强大，她能得到一切她想得到的东西，包括她一生都不曾学会的爱，她是艺术家，但不是那种多情而博爱，对万事万物都充满了热烈激情的艺术家，她是这样的艺术家，情感指向是单一的，心灵空间是逼仄的，心无旁骛的局限却也能营造出强大的艺术能量，一如她诠释的肖邦。</p>
<p>　　伊娃 爱的动机<br>　　伊娃说，她不会爱，她没有爱的能力。伊娃的丈夫对夏洛特说，伊娃并不爱他。这是因为她从小就长在一个无爱的环境里，每一次渴望被爱的愿望都归于幻灭。这让我想起了张爱玲的《金锁记》里曹七巧的女儿长安。和伊娃一样，她也长在一个无爱的环境里，有一个不懂得爱，甚至以折磨她为乐的母亲。但和伊娃的成长完全不一样，长安继承了她母亲的所有，成为曹七巧第二，而伊娃则在本能的驱使下，不由自主地朝着与母亲相反的方向发展。她也渴望被爱，她却是以拼命付出爱的方式来渴望被爱的。在母亲强大阴影的笼罩下，她极其谦卑，极其压抑地爱着，孤独地爱着，绝望地爱着，爱得不到回应给她的心灵造成了致命的伤害，使她对自己爱的能力产生了深深的怀疑，她的爱从此得不到生长，刚刚萌芽的青翠娇弱的爱的嫩叶凝滞了，而她用尽全身每点力气蓄积起的汹涌压抑的爱找不到适合的倾泻的出口。因此当她有了自己的孩子时，他蕴积多年的爱终于得以喷薄而出，这是她的孩子，和她一样天真柔弱的孩子，不幸，孩子夭折了，她新生的爱也夭折了，心灵的残缺再也没有弥补的可能。</p>
<p>　　伊娃 恨的动机<br>　　爱不成，便生恨。恨总缘于爱，恨也总比爱更难，它永远是把双刃剑，伤自己比伤别人更深。对伊娃来说，更是如此。她的恨伤不着她的母亲，而只能跟深更深地伤害自己，因为恨的每一分增长都伴随着摆脱不掉的爱的每一分增长。在那个深夜，伊娃借着酒劲，对母亲发泄了郁积多年的恨，仍然是独白，她声嘶力竭的话语里所传达的情感离她母亲的心灵仍然是那么遥远。女儿喝酒，母亲抽烟，酒是浓烈的，烟是轻漠的，酒是热的，烟是冷的，女儿在酒里暴露自己，母亲在烟中逃避自己，影片好几次将镜头定格在母女俩的面部特写中，女儿爱恨交织的痛苦扭曲的面孔和母亲冷漠麻木的面庞形成鲜明的对照。伊娃不会恨，不会真正的恨，单纯的恨，她孕育的恨的婴儿有根剪不断的爱的脐带。当母亲离去，恨的动机隐退，爱又悄然滋生，她又一次热切地渴望母亲的到来，首尾的呼应似乎预示着爱恨轮回的无休无止。</p>
<p>　　海伦娜 未形成的动机<br>　　如果说一生都未摆脱母亲的阴影的伊娃是个深刻的悲剧的话，有病的海伦娜则是个未成型的悲剧。片中没有交代她病的缘起，我把它看做是一种宿命。这位姑娘以孱弱，极需关怀的形象出现在她母亲面前，而她母亲确是个最不愿关怀别人得人。但即使是这样残缺的躯体内，也仍蕴藏着她那优秀母亲不具备的爱的潜能。当那个忧郁的大提琴手贸然进入她的视线时，我们借伊娃的目光看到了爱情可以使一个少女获得怎样的新生。低沉的提琴旋律回荡在昏暗的房间内，唯一的一束明亮的光投射到海伦娜的脸庞上，为她蒙上了一层神圣的光辉。然而就是这唯一的一线光，一次新生，也被母亲轻描淡写地无意扼杀了。提琴手抗拒不了母亲耀眼的光辉，离她而去，她病情立即恶化，生命从此更加黯淡。比起伊娃，她被母亲毁的更加彻底，连形成一个有价值的悲剧的可能都没有，但在情感的本质上，她与伊娃是同构的：渴望被爱–得不到爱–绝望地爱。片中母女第一次见面，母女都努力地笑，母亲止不住心里的厌恶，仍要努力地笑，女儿面部肌肉已经僵硬，仍努力地笑着，以表达心中极大的喜悦。在苦痛的梦魇里，海伦娜本能的呼号仍是含混不清的”妈妈”。而在另一个意象层面上，她与她母亲形了某种同构：弱者。她母亲一直努力将自己打扮成一个惹人怜爱的弱者，海伦娜则是一个真正的本色的弱者。影片中有一段，母亲躺在地板上向伊娃哭诉己需要爱，需要帮助。镜头切换到沉入梦魇的海伦娜，她在地板上挣扎着爬行呼号，两段镜头不断的切换，形成叠印的效果。至此，母女三人的生命已经死死地纠缠扭合到了一处，尽管她们有如此的不同，彼此灵魂如此的不相通，但从对被爱的极度渴望这个层面上来说，她们都是弱者。</p>
<p>　　亲情是最原始，最本能的情感，因此伯格曼选择它而不是爱情来诠释爱。爱可以成为人的弱点，因为爱是柔软的，让人心软，惟其如此，在崇尚坚硬的世界里，爱才显得弥足珍贵，爱也是沉重的，它需要人付出的太多，惟其如此，在侏两必争的社会里，爱才显得不可多得。爱又是需要回应的，爱得不到回应，是对人心灵的最大伤害，相互回应的爱使心灵相通，是拆除萨特所谓”墙”的唯一方法。否则，就只有孤独的独奏。秋之奏鸣曲奏出无爱的苦痛，心灵的阻隔，奏出人对爱的永恒的渴望。 </p>

        <p>在Python解释器中输入“import this”会发生什么？</p>
<p>Foretec(一家会议组织公司)正在准备召开第十届International Python Conference(IPC 10，Pycon的前身)，Foretec打算征集一条印在会议T恤衫上的标语，最终他们从Python社区收到了500多条投稿。Foretec邀请了Python的核心开发Guido, Fred, Jeremy，Tim Peter，Barry 等来担任评审。评审委员们从投稿中过滤出了130多条后就一直没有进展，直到会议快要召开时他们也没有确定最终标语。会议就要开始的前几天，到了评审们不得不做出决定的时候了。于是由Tim Peter和Barry 两人轮流评审，每人每次淘汰一半留下一半，直到最后只剩一条。最终，“import this”被选了出来，大家对”import this”非常满意。但是当选择了这条以后，他们意识到他们必须要实现它。经过简单的讨论后，“import this”的被定为输出Tim Peter写的《The Zen of Python》——Python编程和设计的指导原则。</p>
