1.直接指定spfile到共享盘是无效的， 配置failsafe时，spfile需要先转换成pfile， 之后用OracleFailSafeManager将这个pfile转换成spfile，放到共享盘上， 2.spfile是一定需要放在共享盘上的。 补充一下，做failsafe时，你必须有一个pfile文件，...

1：最有可能就是CPU过热，检查一下CPU风扇是不是不转了，或转动有问题。 2：可能是你的显卡过热，一般只会出现花屏，但有的也会造成重启。3：删掉显卡驱动，重新装显卡，再重装驱动。然后在显示属性里把刷新率调低（保险点到60Hz）然后接上新显示器，在试试看能不能调高刷新率。4：内存条出错，内存条拔了再插一下试试5：CPU风扇是不是不转了，或转动有问题。

射频开关的控制方式有两种：Latching（锁存）和failsafe。在Latching方式下,切断控制信号后，开关保持在当前的位置，因此可以使用脉冲信号控制开关状态。failsafe方式下,控制电压的撤除导致开关返回到缺省位置(故障自动保险)。容向 www.emcdir.com －专注于电磁兼容方向

它是形容词，意思是 有故障保险功能的; 有自动防障功能的例：The camera has a built-in failsafe device which prevents it from working if the right signals aren"t received.这部照相机内部有故障保险装置，可以令照相机在未接收到正确信号时无法运行。

failsafe的意思是：（核弹运载机等）具有安全装置的；故障（自动）保险的；安全的。（使）具有自动保险装置。一、例句1、Some areas should be kept secure as a failsafe because mustard gas can be very persistent in the environment, he warned.部分地区必须采用故障保险机制，因为芥子气在环境中可以长久的存留。2、Try logging in with one of the failsafe sessions to see if you can fix this problem.可以试试以某个安全模式会话登录，以便查看是否可以解决此问题。二、FailSafeFailSafe的功能相当强大，笔电拥有者的掌握度将能大幅提升，加上拜网络发达所致，笔电本身都配有网卡，只要有FailSafe机制的笔电，就能自动跟服务器连结，笔电遭窃的使用者仍可通过网络对笔电下指令，除了可以追踪笔电所在位置，亦能对笔电进行档案加密或删除等动作，甚至让笔电无法开机。

您是要填词吗？itiskindacttohelpthemtocrosstheroadinsafety。意思是：帮助他们安全过马路是善良的行为。

英文“safe”可以提供防范的要点包括：Secure（安全为先）、Avoid（躲避危险）、Flee（逃离灾难）、Engage（缓兵欺敌）。safe的解释为“安全的；可靠的；平安的”，作名词时意为“保险箱；冷藏室”等。不过在约会防暴中，safe有一个新的内涵，safe可以提供防范的要点包括以下四点：1、S，是Secure的第一个英文字母是指防暴必须考虑寻求安全为先。约会需要将安全条件放在第一顺位考量，比如说和第一次见面的人约会，可能的话，可以要求由好朋友陪伴，或是约在较为公开、明亮的地点见面，能寻求到安全，是约会的最基本要求。2、A是Avoid的第一个英文字母即躲避危。是指防暴如果在不能考虑寻求安全为先的状况下，则必需以躲避危险为次，比如说如果发现约会的对方有问题，约会的地点不恰当，当事人就要拒绝约会，或是展延约会的日程，以躲避可能在约会时会发生的危险。3、F，是Flee的第一个英文字母逃离灾难。是指防暴如果在不能考虑以躲避危险为次时，则必需要以逃离灾难为再其次防暴策略，比如说如困正在约会时，判断对方有不良的企图，便立即要逃离危险的地点，离开有危险倾向的加害人。4、E，是Engage的第一个英文字母即缓兵欺敌。是指防暴如果在不能考虑以逃离灾难为再其次的策略时，则最后的防暴策略是必需要缓兵欺敌。比如说在约会时，判断对方有不良的企图而无法立即逃离时，便需要以缓兵之计欺瞒对方。例如假装答应愿意和他有性行为，但是要换个地方，或是以其它理由，如身体不适、身染疾病拖延歹徒可能加害的立即危险。

使用 protect guard 或 safeguard 要看 object是什么. safeguard 的 object多数是 abstract noun 用 safeguard 牵涉 law regulation contract agreement e 用哪一个字有时要看subject是什么. 如果是人 soldiers police security guard 看守 尤其戒备深严 多数用 guard. 这个字”protect” 是比较普遍用. protect - (防卫 保护) to keep someone or something safe from harm damage or illness. protect something/someone against something/someone protect something/someone from something/someone Don"t worry I"ll protect you. The ernment wants to protect the environment. Eating healthily helps to protect against many diseases. . guard - (看守 守卫 保卫) to protect a person place or object from attack or danger by staying near them and watching them guard something/someone against something guard against something guard against doing something Police officers guarded the entrance to the building. He is guarded by armed men. Nurses should guard against being attached to their patients. (不能用protect safeguard) safeguard - (保卫 保护) to protect something important such as people"s rights interests jobs health etc from loss harm or damage. safeguard something against something The deal will safeguard 200 jobs at the factory. Laws should do more to safeguard the rights of victims. 有时 protect and guard can be used interchangeably.有时不能 ~ a closely guarded secret. 参考: Longman English Dictionary

原因：1、传感器受损、接触不良或信号中断；2、发动机保养不良；3、燃油和机油质量不好；4、混合气燃烧不充分；5、火花塞故障、点火线圈故障；6、燃油泵故障，油路堵塞；7、空调滤芯堵塞1、传感器问题；这里所说的传感器包括水温、曲轴位置、空气流量、进气温度、氧传感器等，当这些传感器受损，接触不良或信号中断时，汽车的ECU就不能准确获得发动机的数据，此时就会引起发动机故障灯亮。2、保养问题；发动机保养不良是引起发动机故障亮起最常见的原因。我们知道，车辆都是有一定的保养周期的，如果车主不按期保养，再加之不良的驾驶习惯，那么就会加重发动机运行的负担，最终只能通过故障灯来提醒你该去关心下你的爱车了3、油质问题；这里说的油质包括燃油和机油，我们知道，汽车加注的燃油一般是有标号的，而机油也有半合成和全合成之分，厂家一般都会推荐车主使用哪种标号的燃油，哪种类型的机油，如果车主没有按要求添加，长期下去就会造成发动机的磨损，那故障灯亮也不怪谁了。混合气燃烧不良；发动机的火花塞故障、点火线圈故障、燃油泵故障、油路堵塞等都会引起发动机混合气燃烧不良。混合气燃烧不良带来就是发动机积碳或爆震问题，而这些最终会被发动机的氧传感器监测到，报告给ECU后，自然是亮起故障灯以示警告进气问题；发动机里面燃烧的时候就需要进气，在这个过程中空气滤芯显得非常重要，汽车的空气滤芯如果不干净，没有定期清理就会影响汽车的进气，长期这样就很可出现堵塞，严重的话就会引起发动机故障灯亮起。增压问题；进气增压管路、涡轮增压器也会导致发动机故障灯点亮。其中最常见的是涡轮增压器损坏，同时车辆还会出现漏油、机油消耗量大、动力下降、金属异响、排气管冒蓝烟或黑烟等症状。7、排气问题；后氧传感器、三元催化器、排气凸轮轴及轴瓦。其中最常见的是三元催化器故障导致发动机故障灯点亮。

原标题：4 biggest challenges in moving to Scaled Agile Framework (SAFe) Adopting the Scaled Agile Framework, or SAFe, can be tricky, and some parts more so than others. Here are some of the biggest challenges and suggest some techniques to make potential problem areas easier to overcome. (Note: We"re assuming you have some familiarity with SAFe. If you don"t, or you simply need a refresher, see my introductory TechBeacon article , posted last month.) So what are the top problem areas? There are other elements that will need to be addressed, including how to prove that SAFe is measurably benefiting the organization, how to create a transformation team, how to move to SAFe-style portfolio budgeting, and more. I will share my thoughts on those passion areas down the road. For now, let"s focus on the following four problem areas: I have seen clients stall in the process of defining their initial epics. Because defined epics are the fuel for the train, stalling or failing to understand this part of the process can derail things quickly. But defining initial epics doesn"t have to be that hard. First, let me clear up some misconceptions. There are technically four categories for epics, and each is a combination of two categories: Each of these can cause some confusion, so let"s clear this up. Before SAFe came along, people used the word epic to indicate a user story that was too big to fit into one sprint but was otherwise exactly the same and even written the same way. "A user can" or "As a I want to so that." But in SAFe, this is not the case. Clear that definition from your mind. Instead, SAFe defines an epic as "enterprise initiatives that are sufficiently substantial so as to warrant analysis and understanding of potential ROI before implementation." SAFe also advocates creating a lightweight business case for each epic. This should sound familiar. In the pre-SAFe world, this would be similar to the definition of a software project or program. Both require a business case. Both require an ROI analysis before funds can be allocated to it. The big difference is that once a project is funded, a team must be created to work on it. In SAFe, approved epics are pulled by a pre-existing train. This follows the same pattern you see in scrum, asking for dedicated teams but, as usual for SAFe, on a much larger scale. For example, this team is 50 to 125 people instead of 5 to 9 people. There is a strong misconception that every program epic must be a child to a portfolio epic. But the real definition is simple: A portfolio epic spans multiple agile release trains (ARTs). A program epic belongs to a single ART. That"s it. The few portfolio epics are broken down into program epics — generally one per train that is involved in the portfolio epic — and that is where people seem to get confused. But this is the exception, not the norm! Imagine if there were zero overlap between trains (the ideal state in train design). There would be no portfolio epics, just program epics. The other extreme is trains that are so poorly designed that every epic requires multiple trains to deliver value. In this case, 100 percent of the program epics would trace back to a portfolio epic, and that would defeat the whole idea of trains being dedicated teams delivering concept to cash value. To add to the confusion, both program epics and portfolio epics are generally kept on one backlog, called the portfolio backlog. Portfolio epics originate from the program portfolio management team, while program epics originate from a train. A train can create a program epic as a stand-alone epic, or they may see a portfolio epic that they are a part of and create a program epic to scope their part of the portfolio epic. Both, however, go through the portfolio Kanban (think project pipeline) to ensure transparency and good metrics on throughput. So to recap, here is the important part. From the ART perspective, all epics are program epics. Only some link back to a portfolio epic. Now, what is the realistic blend of program vs. portfolio epics? Think 80/20, where 20 percent are portfolio. In fact, SAFe talks about having trains create a budget reserve for portfolio epics and keeping the rest for local program epics. That budget could easily be split along 80/20 lines. There is less confusion about business and architectural epic categories. Business epics provide value to your customers, while architectural epics improve the portfolio"s ability to deliver value as well as the quality of the value delivered. But the one spot of confusion I see is that there are also architectural features, and teams believe that they all originate from architectural epics. In fact, architectural features can come from either business or architectural epics. So, if the above is now clear (or at least clearer), we can focus on how to identify your epics. Most companies I work with already have a pipeline of projects that have not yet been funded. They have an intake process for new projects. Some call them proposals and flip them to "projects" only after they are funded. The fastest way to get your initial epic set is to convert your current proposals, projects, and programs to epics. This will also help you start to realize what your trains might be. Think of permanent program teams instead of assembling teams. Your current programs and projects already have teams working them, and these could actually become your initial trains of dedicated resources as well. More than any other part of SAFe, my clients seem confused on the real definition of a value stream. But with an easy-to-understand example, we can unlock the answer. But there"s one important thing to remember: the purpose of a train in SAFe. Traditional unscaled agile methodologies such as scrum ask for "dedicated teams" to ensure a stable velocity. SAFe asks for dedicated large teams to ensure stable project throughput. These are teams of 50 to 125 dedicated people. And as noted above, they call this team an agile release train, or ART. And like an agile team, the goal is for them to be completely self-sufficient. Or close to it. OK, now on to an example that most everyone can understand. Imagine we have a company called Nanosoft, and that it has three major profit centers: productivity software, operating systems, and consulting. What should these three ideas become? The immediate thought is that they would be great value streams, since each is a separate source of value. The truth is, with SAFe, it"s all about size. SAFe solves the problem of large teams or multiple teams that have functional dependencies between them. And their sweet spot is 50-plus people. So, in this example, imagine there are only 20 developers for all three of these value streams. It wouldn"t make sense to have three trains. In fact, you may not need SAFe at all since you are below the 50-person mark. (Of course, if these 20 people all had SAFe experience, they would likely still steal a lot of the best practices from SAFe despite their smaller-than-50 team size.) But now let"s imagine we have 50 to 125 developers for each of those three value areas. Now we have a choice: You could have one value stream with three trains: productivity software train, operating systems train, and consulting train. (You may be asking, "What if the consulting train didn"t develop software?" That is a topic for another article: SAFe for non-software development.) Or, you could have three value streams, each with a single train. My advice here: start simple, and expand only when evidence shows you should. So, in this case, create one train. Now let"s scale up even further. Imagine the value streams have a whole lot of developers. Imagine that for productivity software we have four major products: NanoEdit, NanoSheet, NanoPresenter, and NanoPlanner. Further, operating systems includes PC, mobile, and cloud. Each of these seven product areas has between 50 and 125 developers. Now we have a case for creating three value streams, each with multiple trains. The trains are a dedicated team of 50 to 125 people, and that is the number one driver as to how many trains and value streams you will need. Start as simple as possible — one train, one value stream — unless you have more than 125 people. If you do have more, look to your current lines of business for guidance. If you are developing software for internal clients, value streams are about either your internal products or the client types you have. Ensure you put a skill growth system in place to find skill gaps in your trains and close them as much as possible. Many teams have gotten to the release planning session and found their readiness to be lacking and the momentum to be less than they had hoped for. Others hit the ground running. To figure out how to be in the latter group, we need to study the two-day agenda of the planning meeting. Take a look at the SAFe diagram . If you click on the two-day agenda for the release planning session (find it in the middle tier, right of center, under a yellow, 90-degree inverted tab called "Release Planning"), it may seem overwhelming, at least at first. I"m a big fan of simplification. So here is a simplification. Each of the two days can each be understood as having three identical parts: kick-off, breakout, and wrap-up. It"s simply a matter of understanding how the three parts differ by day. On day one, the kick-off focuses on just four things: sharing the business context, the epic vision, the architecture vision, and the top 10 features for the program increment (along with explaining how to do the breakouts). That"s it! We need to prep these if we want a strong release planning event. The day one breakout is fairly straightforward. Teams allocate stories across four sprints (you can adjust this, but four is the recommendation from SAFe). Right now, I expect a ton of agilists to be leaping out of their seats. "Four sprints? That"s waterfall!" Further, SAFe mentions that 70 percent of these stories should be ready before the release planning event starts, which flies in the face of two big agile concepts: creating your stories together, since the conversation is critical to understanding the story, and doing the stories in the sprint when they are due. (Yes, folks, some teams never do any story refinement/grooming and only refine stories for the sprint within the sprint!) So this is definitely at the other extreme. However, the teams still collaborate to form estimates and acceptance criteria and to task the stories, and they can adjust stories during the breakout sessions. Also, part of the breakouts is to abstract the many features into a smaller set of program increment (PI) objectives for the team. Teams also identify risks and impediments. Scrum masters meet. The wrap-up on day one is where the teams present their PI objectives and risks. Contrary to what you might think, the objectives are rolled up to the program, not down to the teams. They are an abstraction of the stories to make things more digestible at the program level when there are a bunch of teams with lots of stories at the team level. They also present risks, and they are likely not done with the work. Also part of the wrap-up is that all of the teams take off and senior management sticks around to create action plans to mitigate the risks presented by the teams in their draft plan. Day two shares the same pattern. Characteristics of each part follow. On the day two kick-off, management presents risk solutions. The teams break out to finish their work. But this time, the business owners come around and put a value score on the PI objectives. Finally, in wrap-up, the updated plans are presented and a confidence vote is taken (how confident are we that we can deliver what we came up with?), a retrospective is run on the event, and the event is over. I hope this simplification of three identical parts per day makes the default calendar in SAFe a lot less intimidating to master and a lot easier to prepare for. The fourth challenge I want to discuss is ensuring code quality. With two-week sprints, I have seen some ugly engineering shortcuts happen. But the one thing I most worry about, and encourage you to look for, are stories that are really tasks and not units of business value. A story should represent some value to the business. It should be refined (with understood requirements), developed according to a good architecture, tested, and deployed to an agreed-upon environment. If your stories are just fragments of this, you"ve missed the boat. I"ve seen four sprints where sprint 1 is all requirements and sprint 4 is all test work. Hello, waterfall! So how do we improve this? I have a theory, which starts by asking a question: What happens when you teach agile to a team that has poor engineering practices? Poor techniques for requirements, architecture, development, test, and deployment? You probably guessed it. It does bad work a whole lot faster. So my first piece of advice is to ensure teams have strong, modern engineering practices before you let them go agile! What are these practices? I don"t have enough room in a single article to go into depth on each of these, but mastering these practices is critical to "going agile" effectively. It"s much easier to master the agile ceremonies: release planning, sprint planning, stand ups, collaboration sessions, sprint reviews (demos) and retrospectives. It"s much harder to do excellent engineering in two weeks. Ensure your base engineering practices are strong, or make effo

如果你建一个Swift工程，当你创建一个C文件时，然后添加一些方法，比如返回char*类型方法（已经桥接完成），然后你在Swift中书写这个C定义的方法时，xcode会自动转换到swift中的类型。char*对应UnsafeMutablePointer，const char*是UnsafePointer。好了，我开个简单的头。看文章主要内容。大多数时候，C语言指针有两种方法导入到Swift中：UnsafePointer<T>UnsafeMutablePointer<T>这里的T是C类型的等价的Swift类型。声明为常量的指针被导入为UnsafePointer，非常量的指针则被导入为UnsafeMutablePoinger。这里有一些示例：C:void myFunction(const int *myConstIntPointer);Swift:func myFunction(myConstIntPointer: UnsafePointer<Int32>)C:void myOtherFunction(unsigned int *myUnsignedIntPointer);Swift:func myOtherFunction(myUnsignedIntPointer: UnsafeMutablePointer<UInt32>)C:void iTakeAVoidPointer(void *aVoidPointer);Swift:func iTakeAVoidPointer(aVoidPointer: UnsafeMutablePointer<Void>)如果不知道指针的类型，比如一个为前置声明的指针，则使用COpaquePointer。C:struct SomeThing;void iTakeAnOpaquePointer(struct SomeThing *someThing);Swift:func iTakeAnOpaquePointer(someThing: COpaquePointer)传递指针到Swift对象在很多情况下，传递指针到Swift对象和使用inout运算符一样简单，后者类似于C语言中的and运算符。Swift:let myInt: = 42myFunction(myInt)var myUnsignedInt: UInt = 7myOtherFunction(myUnsignedInt)这里有两个非常重要但容易被忽视的细节。当使用inout运算符时，使用var声明的变量和使用let声明的常量被分别转换到UnsafePointer和 UnsafeMutablePoinger，如果你不注意原来代码中的类型，就很容易出错。你可以试着向本来是UnsafeMutablePoinger 的地方传递一个UnsafePointer看看，编译器会报错。2. 这个运算符只在将Swift值和引用作为函数参数传递的上下文时生效，且该函数参数只接受UnsafePointer和UnsafeMutablePoinger两种类型。你不能在其它上下文获得这些指针。比如，下面的代码是无效的，并且会返回编译错误。Swift:let x = 42let y = x你可能会不时的需要交互操作一个API。来获取或返回一个空指针以代替显式类型，不幸的是这种做法在C语言里很普遍，导致无法指定一个通用类型。C:void takesAnObject(void *theObject);如果你确定函数需要获取什么类型的参数，你可以使用withUnsafePointer和unsafeBitCast将对象强制转换为空指针。比如，假设takesAnObject需要获取指向int的指针。var test = 42withUnsafePointer(test, { (ptr: UnsafePointer<Int>) -> Void invar voidPtr: UnsafePointer<Void> = unsafeBitCast(ptr, UnsafePointer<Void>.self)takesAnObject(voidPtr)})为了转换它，首先我们需要调用withUnsafeMutablePointer，这个通用函数包含两个参数。第一个参数是T类型的inout运算符，第二个是(UnsafePointer) -> ResultType的闭包。函数通过指向第一个参数的指针来调用闭包，然后然后将其作为闭包唯一的参数传递，最后函数返回闭包的结果。在上面的例子里， 闭包的类型被设置为Void，因此将不返回值。返回值的例子如下：let ret = withUnsafePointer(test, { (ptr: UnsafePointer<Int>) -> Int32 invar voidPtr: UnsafePointer<Void> = unsafeBitCast(ptr, UnsafePointer<Void>.self)return takesAnObjectAndReturnsAnInt(voidPtr)})println(ret)注意：你需要自己修改指针，通过withUnsafeMutablePointer变体来完成修改。为方便起见，Swift也包括传递两个指针的变体：var x: Int = 7var y: Double = 4withUnsafePointers(x, y, { (ptr1: UnsafePointer<Int>, ptr2: UnsafePointer<Double>) -> Void invar voidPtr1: UnsafePointer<Void> = unsafeBitCast(ptr1, UnsafePointer<Void>.self)var voidPtr2: UnsafePointer<Void> = unsafeBitCast(ptr2, UnsafePointer<Void>.self)takesTwoPointers(voidPtr1, voidPtr2)})关于unsafeBitCastunsafeBitCast 是一个极度危险的操作。文档将其描述为“将某物强制转换为和其他东西相同的长度”。在上面的代码我们能够安全的使用它的原因是，我们只是简单的转换不同类型的指针，并且这些指针的长度都是相同的。这也是我们为什么必须先调用withUnsafePointer来获取UnsafePointer，然后将其转换为UnsafePointer的原因。在一开始这可能会造成迷惑，特别是当处理与指针相同的类型时，比如Swift里的Int（在目前所有可用的，一个指针的长度是一个字符，Int的长度同样也是一个字符）。比如很容易就会犯下面的错误：var x: Int = 7let xPtr = unsafeBitCast(x, UnsafePointer<Void>.self)这段代码的意图是获取一个指针并传递给x。它会给人造成误解，尽管编译能通过并且能运行，但会导致一个意外错误。这是因为C API没有获取指针并传递给x，而是接收位于0x7或者其他地方的指针。因为unsafeBitCast要求类型的长度相等，所以当试图转换Int8或者一个字节的整型时没那么阴险了。var x: Int8 = 7let xPtr = unsafeBitCast(x, UnsafePointer<Void>.self)这段代码会简单的导致unsafeBitCast抛出异常和程序崩溃。与C语言中的结构体交互让 我们用实际的示例来展示这一部分。如果你想检索计算机所运行的系统信息，有一个C API：uname(2)可以达到目的。它接收指针指到一个数据结构，并且用系统信息填充所提供的对象，如OS名称和版本或者硬件识别符。但这里有一个问 题，导入到Swift的结构体是这样：struct utsname {var sysname: (Int8, Int8, 253 times, Int8)var nodename: (Int8, Int8, 253 times, Int8)var release: (Int8, Int8, 253 times, Int8)var version: (Int8, Int8, 253 times, Int8)var machine: (Int8, Int8, 253 times, Int8)}Swift将C中的数组字面量作为元组导入，并且默认的初始化程序要求每个字段都有值，所以如果你用Swift通常的做法来做的话，它将会变成：var name = utsname(sysname: (0, 0, 0, , 0), nodename: (0, 0, 0, , 0), etc)utsname(name)var machine = name.machineprintln(machine)这不是一个好方法。并且还存在另一个问题。因为utsname里的machine字段是元组，所以当使用println时将输出256位的Int8，但实际上只有字符串开始的几个ASCII值是我们需要的。那么，如何解决这个问题？Swift里的UnsafeMutablePointer提供两个方法，alloc(Int)和dealloc(Int)，分别用来分配和解除分配模板T的数量参数。我们可以用这些API来简化我们的代码：let name = UnsafeMutablePointer<utsname>.alloc(1)uname(name)let machine = withUnsafePointer(name.memory.machine, { (ptr) -> String? inlet int8Ptr = unsafeBitCast(ptr, UnsafePointer<Int8>.self)return String.fromCString(int8Ptr)})name.dealloc(1)if let m = machine {println(m)}第一步是调用withUnsafePointer，将机器的元组传递给它，并通知它我们的闭包将返回一个附加字符串。在 闭包里面我们将指针转换为UnsafePointer，即该值的最等价的表述。除此之外，Swift的String包含一个类方法来初始化 UnsafePointer，这里的CChar是Int8类型的别名（typealias），所以我们能够将我们的新指针传递给初始化程序并且返回所需要 的信息。在获取withUnsafePointer的结果之后，我们能够测试它是否是let的条件声明，并打印出结果。对这个例子来说，它输出了期望的字段“x86_64”。总结最 后，说一下免责声明。在Swift中使用不安全的API应该被视为最后手段，因为它们是潜在不安全的。当我们转换遗留的C和Objective-C代码到 Swift中，有很大可能性我们会继续需要这些API来兼容现有工具。然而，当使用withUnsafePointer和unsafeBitCast作为 首选手段时应该始终抱有怀疑态度，并寻找其他更好的解决方案。新的代码应该尽可能符合语言习惯，不要在Swift代码中使用不安全的API。作为开发者，你应该了解如何使用你的工具以及什么地方该使用和什么地方不该使用。Swift将现代化带给了OS X和iOS开发，我们必须尊重它的理念。

1. 解答: 原句为简单句，但在结构上看不是主谓双宾结构，而是主谓宾结构。句中Road safety advocate和Eleanor不是双宾语关系，而是复指关系，因此只能形成主谓宾结构。2. 拓展: 英语中最基本的句子样式被称为简单句。可以给简单句这样下定义: 一个句子，不论长短，只要它所包含的所有成分只能由单词或者短语表示，那么这个句子就是简单句。简单句有五种结构类型，类型划分的依据在于谓语动词。谓语动词由系动词（be, become, get, turn, feel, sound,taste, smell, remain, stay, 等等）充当的，归入主系表结构。英语常见的there be句型也属于主系表结构。谓语动词由实义动词充当的，再根据实义动词的不同而进一步细分。实义动词包含不及物动词和及物动词两种。不及物动词后面不可以跟宾语，由它充当谓语动词的简单句只能划分为主谓结构。及物动词后面可以跟宾语，而且宾语的数量可能是一个，也可能是两个，甚至某个宾语后面还可以有补足语，这样简单句就可以进一步划分为主谓结构，主谓宾结构，主谓双宾结构和主谓宾加宾补结构。下面举例进行说明。3. 举例:① There is an old my sitting under the tree.有一位老人坐在树下。② I have to get up very early tomorrow morning.我明天早上必须早早起床。③ Can I have some cake now, Mom? 妈妈，我现在就能吃一些蛋糕吗？④ I am writing my uncle an e-mail now. 我正在给叔叔写电子邮件。⑤ I don"t think it easy to learn to skate. 我并不认为学会滑冰很容易。

故事 是用用户语言编写的一小块所需功能的简短描述。 敏捷团队 实现的是系统功能的小的、垂直的切片，其大小可以在单个 迭代 中完成。 故事是敏捷中用来定义系统行为的主要工件。它们是对功能的简短描述，通常从用户的角度出发，用用户的语言写成。每一个故事的目的都是为了实现系统行为的一个小的、垂直的片断，以支持增量开发。 故事提供了足够的信息，让业务人员和技术人员都能理解其意图。故事的细节将被推迟到故事准备实施之前才讨论。通过验收标准和验收测试，故事变得更加具体，有助于确保系统质量。 用户故事（User stories）将功能直接交付给最终用户。使能故事（Enabler stories）为支持探索、架构、基础设施和合规性所需的工作项带来了可见性。 SAFe的 需求模型 描述了工件的四层结构，这些工件概述了功能系统的行为： 史诗（Epic） ， 能力（Capability） ， 特性（Feature） 和故事（Story）。他们共同描述了创建解决方案预期行为的所有工作。但详细的实施工作是通过故事来描述的，这些故事构成了 团队Backlog 。大多数故事来自于“ Program Backlog” 中的业务和使能特性（Feature），部分故事来自于团队识别的工作。 每个故事都是一个小的、独立的行为，可以逐步实现，并为用户或 解决方案（Solution） 提供一些价值。它是功能的垂直切片，以确保每次迭代都能带来新的价值。故事要拆分得相对较小，必须能在一次迭代中完成（参见拆分故事部分）。 通常情况下，故事会先写在索引卡或便签上。索引卡的物理性质在团队、故事和用户之间建立了一种有形的关系：它有助于让整个团队参与到故事编写中来。便签纸还提供了其他的好处：它们有助于将工作可视化，并且可以很容易地放在墙上或桌子上，按顺序重新排列，甚至在必要时传递。故事可以让人们更好地了解工作的范围和进度： 虽然任何人都可以写故事，但批准它们进入团队待办列表并接受到系统基线中是 产品负责人 的责任。当然，便利贴并不能很好地在整个 企业 中扩展，所以故事通常会迅速转移到敏捷生命周期管理（ALM，Agile lifecycle management）工具中。 在SAFe中，有两种类型的故事，即用户故事和使能故事，如下所述。 如图1所示，故事通常是由业务和使能特性的拆分来驱动的。 用户故事是表达所需功能的主要方法。它们在很大程度上取代了传统的需求说明书。（然而，在某些情况下，它们可以用来解释和开发系统行为，这些行为随后被记录下来，以支持合规性、可追溯性或其他需求。） 因为它们关注的是用户感兴趣的主题，而不是系统，所以用户故事是以价值为中心的。为了支持这一点，推荐的表达形式是“用户声音”的形式，如下所示： 通过使用这种形式，引导团队了解谁在使用系统，他们在用系统做什么，以及他们为什么这样做。经常使用“用户声音”的形式往往会提高团队的领域能力（domain competence）；他们会更好地理解用户的真实业务需求。图2提供了一个示例。 “用户画像（Personas）”描述了具有代表性的用户的具体特征，可以帮助团队更好地理解他们的终端用户。 图2中骑手角色的示例可以是一个追求刺激的“Jane”和一个胆小的骑手“Bob”。然后，故事说明将引用这些角色（作为Jane，我希望…）。 虽然用户故事语音很常见，但并不是每个系统都会与终端用户进行交互。有时“用户（user）”是一个设备（如打印机）或一个系统（如交易服务器）。在这些情况下，故事可以采用图3所示的形式。 团队可能需要开发系统结构或基础设施，以实现一些用户故事或系统的支持组件。在这种情况下，故事可能不会直接接触任何终端用户。这些是使能故事，它们支持探索、架构或基础设施。使能故事可以用技术而不是以用户为中心的语言来表达，如图4所示。 还有许多其他类型的使能故事，包括： 使能故事和用户故事一样，通常是通过展示所获得的知识、制作的工件、或用户界面、打桩或模拟来展示。 好的故事需要多个视角的观点。在敏捷中，整个团队（产品负责人、开发人员和测试人员）对要构建的内容有一个共同的理解，以减少返工并提高吞吐量。团队使用 行为驱动开发 (BDD)进行协作，定义详细的验收测试，明确描述每个故事。好的故事需要多角度的思考： 协同编写故事可以确保所有的观点都得到考虑，并且每个人都对故事的行为达成共识，其结果体现在故事的描述、验收标准和验收测试中。验收测试使用系统的领域语言（system"s domain language）与 行为驱动开发 （BDD）来编写。然后，BDD测试将自动执行并持续运行，以保持 内建质量 。BDD测试是根据系统需求（故事）编写的，因此可以作为系统行为的权威性声明（definitive statement），取代基于文档的功能详细说明（document-based specifications）。 Ron Jeffries，XP的发明者之一，被认为是首先提出了描述故事的3C方法： 敏捷团队通常以业务可读的特定领域语言（domain-specific language）自动执行验收测试。自动化创建了一个可执行的规范来验证和核实解决方案。自动化还提供了对系统进行快速回归测试的能力，从而增强了 持续集成 ，重构和维护的能力。 由 Bill Wake [1]开发的 INVEST 模型描述了良好用户故事的特征： 敏捷团队使用故事点和“估算扑克”来估算他们的工作[1，2]。故事点是一个单独的数字，它代表了一组特性的组合： 故事点是相对的，它与任何具体的衡量单位无关。每个故事的大小（工作量）都是相对于最小的故事来估算的，最小的故事被赋予“1”的大小。 应用一个修正后的斐波那契序列（1，2，3，5，8，13，20，40，100），以反映估算中固有的不确定性，特别是大数（如20，40，100）[2]。 敏捷团队经常使用“ 估算扑克 ”，它结合了专家意见（expert opinion），类比（analogy）和分解（disaggregation）来创建快速但可靠的估算。分解是指将故事或特性分割成更小的，更容易估算的部分。 （请注意，还有一些其他的方法也在使用。）估算扑克的规则是： 进行一些初步设计讨论是合适的。然而，在设计讨论上花费太多时间往往是浪费精力。估算扑克的真正价值在于就一个故事的范围达成一致。这也是一种乐趣！ 团队在一次迭代中的速率等于满足完成定义（DoD）的所有已完成故事的故事点数之和。随着团队的不断合作，他们的平均速率（每次迭代完成的故事点）会变得可靠和可预测。可预测的速率有助于制定计划，并有助于限制在制品（WIP），因为团队承担的故事数量不会超过其历史速度所允许的范围。这个衡量标准也被用来估算交付史诗（epics）、特性（features）、能力（capabilities）和使能故事（enablers）所需的时间，这些时间也可以使用故事点进行预测。 容量是指团队速率中实际可用于任何特定迭代的部分。假期、培训和其他事件会使团队成员在迭代的某些部分无法为迭代的目标做出贡献。这就降低了该团队在该迭代中的最大潜在速率。例如，一个平均每迭代交付40点的团队，如果一个团队成员休假一周，他们的最大速率就会调整到36点。提前知道这一点，团队在迭代计划时就只承诺最大36个故事点。这也有助于在PI计划期间预测PI中每个迭代的实际可用容量，从而使团队在构建PI目标时不会过度承诺。 在标准的Scrum中，每个团队的故事点估算以及由此产生的速率是一个团队内部的、独立的事务。从规模化敏捷的角度来看，当各个团队之间的速率的基准分歧很大时，将很难预测更大的史诗（Epic）和特性（Feature）的故事点大小。 为了克服这个问题，SAFe团队最初会校准一个起始故事点基准，在这个基准上，所有团队的故事点定义大致相同。不需要重新校准团队估算或者速率。在启动新的 敏捷发布列车 时，会进行一次校准。 标准化 的故事点提供了一种方法，可以让故事和速率达到一个约定的起始基准，如下所示： 示例 ：假设一个6人团队，由3个开发人员，2个测试人员和1个PO组成，没有请假或节假日，那么估算的初始速率=5×8点=40点/迭代。（注：如果其中一个开发人员和测试人员兼职Scrum Master，可能需要将其调低一些）。 这样一来，各团队的故事点就有了一定的可比性。管理层可以更好地理解一个故事点的成本，并能更准确地确定一个即将到来的特性（Feature）或史诗（Epic）的成本。 虽然随着时间的推移，团队会倾向于提高他们的速率，这是件好事，但实际上，这个数字往往保持稳定。一个团队的速率受团队规模和技术环境变化的影响远远大于受生产力变化的影响。 较小的故事会带来更快、更可靠的实施，因为小的条目在任何系统中流转的速度更快、可变性更小、风险更低。因此，把较大的故事拆分成较小的故事是每个敏捷团队的必备技能。这既是增量发展的艺术，也是科学。Leffingwell的《Agile Software Requirements》[1]中介绍了十种拆分故事的方法。以下是对这些技术的总结： 图6展示了一个按用例场景拆分的示例： 正如 SAFe需求模型 一文中所描述的，该框架应用了一系列的工件和联系，以精益和敏捷的方式管理复杂系统的定义和测试。图7说明了故事在SAFe全局中的作用。 在规模化敏捷中，故事（Story）通常（但并不总是）由新特性（Feature）创建。而每个故事都有验收测试，也可能有单元测试。单元测试主要是为了确保故事的技术实现是正确的。同时，这也是测试自动化的一个关键起点，因为单元测试很容易实现自动化，这在 测试驱动开发 （TDD）一文中有所描述。 注：图7使用统一建模语言（UML）符号来表示对象之间的关系：零对多（0...*），一对多（1...*），一对一（1），以此类推。 Last update: 17 December 2019

当前，有很多人死于交通事故。道路安全引起了很多关注。为了减少交通事故，人们制定了很多交通规则，但效果并不理想。依我个人之见，交通安全应当在日常生活中得到重视。行人走在路上的时候，应当走人行道，我们应当学会如何保护自己。此外，驾驶者应当遵循交通规则，这于己于人都是有好处的。换句话说，道路安全值得每个人去特别关注，毕竟生命是最珍贵的。

最近在做一个移动端的 H5 项目，遇到了一个「有趣」的问题。假设有一页面布局如下： 下方 50px 悬浮于底部，采用 fixed 布局，示例如下： 完整示例请看 CodeSandbox 。 测试下来看似乎没问题，可当你使用 iPhone 的 Safari 浏览器打开此页面时，就会出现如下情况： 截图中已滑动至页面最底部，然而 100 被 TabBar 部分挡住了（其他浏览器均能正常展示出来）。 我们知道， vh 、 vw 都是 CSS 中的一种相对长度单位， 1vh 表示 viewport 高度的 1%（ vm 同理）。简单来讲，viewport 基本上是指当前文档的可见部分，因此 100vh 表示可见文档的最大高度。 可事实真是如此吗？ 在 Safari 浏览器中， 100vh 如下图所示（ 出自 ）： 按上面所说， 100vh 不应该是 viewport 可视区域的全部高度，为什么右图的高度会超出的呢？ 做个简图区分一下吧： 所以，这就是为什么在 Safari 会被挡住一部分的原因。 是 bug 还是故意为之？ 可以详细地看下这篇文章： Viewport height is taller than the visible part of the document in some mobile browsers ，然后文章作者给 WebKit 提了个 bug ，其中 Apple 工程师 Benjamin Poulain 的 回答 如下： So, it"s a feature, not a bug. 然而，并不是只有 Safari 是这样做的，比如 iOS 端 Chrome 浏览器表现与 iOS 端 Safari 一致... (⊙u02cd⊙) 尽管这并不是大多数开发者想要的，但很无奈，我们只能想办法去「修复」它，使得我们的网站在各浏览器表现一致。 方案一：使用 -webkit-fill-available 简单来说，-webkit-fill-available 就是自动填满剩余空间（ 详见 ）。这里使用另一个示例，来说明 -webkit-fill-available 的一些问题，如下： 以上示例，分别会有蓝、红、绿三部分，按预期结果，它们应该会占满整个可视区域（完整示例请看 CodeSandbox ），而 Safari 中底部绿色部分会被挡住。然后我们添加在 body 添加上 - webkit-fill-available 看看： iOS 上的 Safari 中的表现是正常了，但是你会发现 Chrome 下红色区域没了，原因是 Chrome 84 起已不再支持 -webkit-fill-available ，所以实际渲染如下： 那么解决方法就是，针对 Safari 浏览器才设置 -webkit-fill-available 即可，这里利用到 @support 和 -webkit-touch-callout ，如下： 这样就 OK 了，Safari 和 Chrome 表现均如预期一致。这也是 postcss-100vh-fix 插件的解决方案。 然而，以上方案并不适用于这些情况，比如： height: 90vh 、 height: calc(100vh - 50px) ，因此才有了方案二。 方案二：通过 CSS 变量计算 1vh 所表示的实际高度 思路： 实现如下： 使用 vh 时，需要这样兼容处理： 有一个 react-div-100vh 库就是获取 window.innerHeight ，然后将其值设置为容器高度实现的，然而这也是仅可处理 100vh 的情况。 至于使用哪一种解决方案，视乎实际情况而定吧！
