本文摘錄自：DevEx in Action。

文中闡述為什麼優化開發體驗很重要，並依此來設計出一個優質的工作環境。

+

優化工程開發體驗有三個目標要滿足：

+
+

只有這三個嗎？

+

這些只是作者提供的指標，根據情境可以自行設計。

+

但是要注意，根據 PLS-SEM（後面的分析工具）最佳指南， +指標數量越高，樣本數要跟著提高才能降低誤差。

+

總結來說，就會有這三對三的線圖：

總結來說，降低開發的認知負荷對於個人、團體和組織是最有效的。

+
但是這邊的精華在於用數據展示，換句話說，我們可以知道如何衡量改變。
+例如公司開始設計一個工具加速開發，這樣的優化如果可以透過數字知道某方面提升 40%，
+某方面提升 10%，就可以知道這工具的優勢和劣勢，進一步改善。

+
這樣的機制不管是公司目前對於優化開發體驗是剛起步還是正在路上，都能有機制衡量和設定目標。

    KeepConfiguration
     
    Takes a boolean or one of \"static\", \"dhcp-on-stop\", \"dhcp\". When \"static\", systemd-networkd will not drop static addresses and routes on starting up process. When set to \"dhcp-on-stop\", systemd-networkd will not drop addresses and routes on stopping the daemon. When \"dhcp\", the addresses and routes provided by a DHCP server will never be dropped even if the DHCP lease expires. This is contrary to the DHCP specification, but may be the best choice if, e.g., the root filesystem relies on this connection. The setting \"dhcp\" implies \"dhcp-on-stop\", and \"yes\" implies \"dhcp\" and \"static\". Defaults to \"dhcp-on-stop\" when systemd-networkd is running in initrd, \"yes\" when the root filesystem is a network filesystem, and \"no\" otherwise.

This is encountered when opening many files at once in parallel, especially on systems (in particular, macOS) where there is a low file descriptor limit for processes. To remedy a low limit, run ulimit -n 2048 in the same shell that will run the Node.js process.

    I have read tens of books (both in ebook format and also hard copy textbooks) in my networking professional career over the last 18 years.
     
    In fact, all of my preparation for my Cisco and other IT certifications was based on book studying (in addition to hands-on practice of course).
     
    Personally, I believe that having a hard copy book in your hands and reading it from start to finish by taking written notes along the way, is one of the best ways to memorize and learn the material.
     
    In this article I will list and review some of the best books on computer networking for both beginners and expert professionals.
     
    The field of TCP/IP networking is evolving with new technological advancements and, in my opinion, it currently undergoes a transition from purely hardware to more software-based networks.
     
    For the reason above I have also included books in the list (see towards the end) that focus on next generation networks, SDN, and automation/programmability.
     
    When I first wrote this article, I intentionally didn\u2019t include any books related to Cisco certifications because that time was a transitional period for Cisco exams and certifications.
     
    After the dust has settled, there are now some great Cisco books worth mentioning for professionals looking to earn Cisco certifications, so I have included some recommended options in the list.
     
    You will find mostly some great books which teach both the fundamentals and more advanced concepts in computer networking that will surely be very valuable for professionals.
     
    Let\u2019s get started:
    "},{"location":"essay/web/network-books/#computer-networking-a-top-down-approach","title":"Computer Networking: A Top-Down Approach","text":"
    Computer Networking: A Top-Down Approach (6th Edition)
     
    This book is organized into the network layers of Internet Protocol Stack which is the base of all computer networking (together with the OSI model), therefore it offers a very good structure and learning experience.
     
    Written by two University professors (James Kurose and Keith Ross), the book is mostly suited for beginners and for university students in computer science or engineering majors.
     
    Even if people who don\u2019t have any knowledge about networking will find the book easily accessible and comprehensible.
     
    Although currently there is a newer 7th Edition of this book, its much higher price tag compared to the 6th Edition is not worth the extra money.
     
    Also, the newer edition does not include that much extra material so I would recommend the cheaper 6th Edition just to save you some money. Although it is an older book, you will still learn the fundamentals of networking which is the basis for more practical material.
     
    As I said above, the book is called \u201cTop-Down Approach\u201d because it starts at the Application layer of the Internet Protocol Stack (top layer) and works its way down to the Physical layer (bottom layer) of the stack. The other layers examined include Transport, Network and Link layers.
     
    The above structure makes sense a lot in the pedagogical perspective since the whole computer networking functionality is based on this protocol layered structure.
     
    Most useful for:
     
    To summarize, I belief this book is a great choice for beginners or university students to acquire a comprehensive knowledge in computer networking fundamentals.
    "},{"location":"essay/web/network-books/#network-warrior","title":"Network Warrior","text":"
    Network Warrior (2nd Edition)
     
    Unlike the previous book above, \u201cNetwork Warrior\u201d book is much more practical and the examples described in the book are taken from real world networks and from the experience of the author.
     
    The practical examples and configuration samples you will find in the book are taken from actual Cisco networking equipment so the book will be very helpful to Cisco network administrators that are actually working in the field and want to get the job done.
     
    Some of the topics covered in the book include:

    This socket option tells the kernel that even if this port is busy (in the TIME_WAIT state), go ahead and reuse it anyway. If it is busy, but with another state, you will still get an address already in use error. It is useful if your server has been shut down, and then restarted right away while sockets are still active on its port. You should be aware that if any unexpected data comes in, it may confuse your server, but while this is possible, it is not likely.

            In iOS, a developer can use identifierForVendor, which is related to the bundle ID: the moment you change a bundle ID, the method will return a different value. When the app is ran for the first time, make sure you store the value returned by identifierForVendor to the KeyChain, so that changes to it can be detected at an early stage.
             
            Android\uff1a
             
            In Android, the developer can use Settings.Secure.ANDROID_ID till Android 8.0 (API level 26) to identify an application instance. Note that starting at Android 8.0 (API level 26), ANDROID_ID is no longer a device unique ID. Instead, it becomes scoped by the combination of app signing key, user and device. So validating ANDROID_ID for device blocking could be tricky for these Android versions. Because if an app changes its signing key, the ANDROID_ID will change and it won't be able to recognize old users devices. Therefore, it's better to store the ANDROID_IDencrypted and privately in a private a shared preferences file using a randomly generated key from the AndroidKeyStore and preferably AES_GCM encryption. The moment the app signature changes, the application can check for a delta and register the new ANDROID_ID. The moment this new ID changes without a new application signing key, it should indicate that something else is wrong.

            Next, the device binding can be extended by signing requests with a key stored in the Keychain for iOS and in the KeyStore in Android can reassure strong device binding.

            As an application developer you\u2019re armed with this knowledge about the internals of storage engines, you are in a much better position to know which tool is best suited for your particular application. If you need to adjust a database\u2019s tuning parameters, this understanding allows you to imagine what effect a higher or a lower value may have. Although this chapter couldn\u2019t make you an expert in tuning any one particular storage engine, it has hopefully equipped you with enough vocabulary and ideas that you can make sense of the documentation for the database of your choice.

            In my limited experience I\u2019ve dealt with long-lived network partitions in a single data center (DC), PDU failures, switch failures, accidental power cycles of whole racks, whole-DC backbone failures, whole-DC power failures, and a hypoglycemic driver smashing his Ford pickup truck into a DC\u2019s HVAC system. And I\u2019m not even an ops guy.

            It helps in analyzing gravitation to consider a situation where gravity is mocked up by acceleration. Focus attention on a region so far from any attracting matter, and so free of disturbance, that spacetime there can be consider to be flat and to have Lorentz geometry. .... When spacetime is flat, move however one will, special relativity can handle the job.

            Takes a boolean or one of \"static\", \"dhcp-on-stop\", \"dhcp\". When \"static\", systemd-networkd will not drop static addresses and routes on starting up process. When set to \"dhcp-on-stop\", systemd-networkd will not drop addresses and routes on stopping the daemon. When \"dhcp\", the addresses and routes provided by a DHCP server will never be dropped even if the DHCP lease expires. This is contrary to the DHCP specification, but may be the best choice if, e.g., the root filesystem relies on this connection. The setting \"dhcp\" implies \"dhcp-on-stop\", and \"yes\" implies \"dhcp\" and \"static\". Defaults to \"dhcp-on-stop\" when systemd-networkd is running in initrd, \"yes\" when the root filesystem is a network filesystem, and \"no\" otherwise.

              •  
            • ENOENT (No such file or directory): Commonly raised by fs operations to indicate that a component of the specified pathname does not exist. No entity (file or directory) could be found by the given path.
              •  
            • ENOTDIR (Not a directory): A component of the given pathname existed, but was not a directory as expected. Commonly raised by fs.readdir.
              •  
            • ENOTEMPTY (Directory not empty): A directory with entries was the target of an operation that requires an empty directory, usually fs.unlink.

            I have read tens of books (both in ebook format and also hard copy textbooks) in my networking professional career over the last 18 years.
             
            In fact, all of my preparation for my Cisco and other IT certifications was based on book studying (in addition to hands-on practice of course).
             
            Personally, I believe that having a hard copy book in your hands and reading it from start to finish by taking written notes along the way, is one of the best ways to memorize and learn the material.
             
            In this article I will list and review some of the best books on computer networking for both beginners and expert professionals.
             
            The field of TCP/IP networking is evolving with new technological advancements and, in my opinion, it currently undergoes a transition from purely hardware to more software-based networks.
             
            For the reason above I have also included books in the list (see towards the end) that focus on next generation networks, SDN, and automation/programmability.
             
            When I first wrote this article, I intentionally didn\u2019t include any books related to Cisco certifications because that time was a transitional period for Cisco exams and certifications.
             
            After the dust has settled, there are now some great Cisco books worth mentioning for professionals looking to earn Cisco certifications, so I have included some recommended options in the list.
             
            You will find mostly some great books which teach both the fundamentals and more advanced concepts in computer networking that will surely be very valuable for professionals.
             
            Let\u2019s get started:
            "},{"location":"essay/web/network-books/#computer-networking-a-top-down-approach","title":"Computer Networking: A Top-Down Approach","text":"
            Computer Networking: A Top-Down Approach (6th Edition)
             
            This book is organized into the network layers of Internet Protocol Stack which is the base of all computer networking (together with the OSI model), therefore it offers a very good structure and learning experience.
             
            Written by two University professors (James Kurose and Keith Ross), the book is mostly suited for beginners and for university students in computer science or engineering majors.
             
            Even if people who don\u2019t have any knowledge about networking will find the book easily accessible and comprehensible.
             
            Although currently there is a newer 7th Edition of this book, its much higher price tag compared to the 6th Edition is not worth the extra money.
             
            Also, the newer edition does not include that much extra material so I would recommend the cheaper 6th Edition just to save you some money. Although it is an older book, you will still learn the fundamentals of networking which is the basis for more practical material.
             
            As I said above, the book is called \u201cTop-Down Approach\u201d because it starts at the Application layer of the Internet Protocol Stack (top layer) and works its way down to the Physical layer (bottom layer) of the stack. The other layers examined include Transport, Network and Link layers.
             
            The above structure makes sense a lot in the pedagogical perspective since the whole computer networking functionality is based on this protocol layered structure.
             
            Most useful for:
             
            To summarize, I belief this book is a great choice for beginners or university students to acquire a comprehensive knowledge in computer networking fundamentals.
            "},{"location":"essay/web/network-books/#network-warrior","title":"Network Warrior","text":"
            Network Warrior (2nd Edition)
             
            Unlike the previous book above, \u201cNetwork Warrior\u201d book is much more practical and the examples described in the book are taken from real world networks and from the experience of the author.
             
            The practical examples and configuration samples you will find in the book are taken from actual Cisco networking equipment so the book will be very helpful to Cisco network administrators that are actually working in the field and want to get the job done.
             
            Some of the topics covered in the book include:
             
               
            • Switches, VLANs, trunking, Link aggregation etc
              •  
            • Routers, routing protocols (RIP, EIGRP, OSPF, BGP), redistribution etc
              •  
            • Cisco devices configuration (4500, 6500 multilayer switches, 3550, 3750 etc)
              •  
            • Cisco Nexus discussion and configuration.
              •  
            • MPLS
              •  
            • ACLs, authentication, NAT etc

            • VoIP
              •  
            • QoS
              •  
            • IP design
              •  
            • IPv4, IPv6
              •  
            • Etc
              •  
             
            Most useful for:
             
            To summarize, this book is great as a practical reference for professionals already working with Cisco networks. Although it is an old book, most of the concepts, configurations and technologies are still valid to this date.

            Network Programmability and Automation: Skills for the Next-Generation Network Engineer
             
            As I have mentioned at the beginning of this article, the book list I have compiled here includes also textbooks that look at the future of networking.
             
            The \u201cNetwork Programmability and Automation\u201d book from O\u2019REILLY Media is one of these books that teaches a next-generation concept for network engineers.
             
            This concept is about automating the management and operation of hardware-based networks using software tools, programming, Application Programming Interfaces (API) etc.
             
            The book covers topics such as Python (used to create useful scripts to automate networking tasks), Linux, IT automation tools such as Ansible, SDN concepts, working with Network APIs, Integration concepts etc.
             
            Keep in mind here that the new Cisco certification exams after their 2020 updates, include a lot of programmability and automation topics. This is another reason that modern network engineers must shift their mindset into more software-based concepts and automation.
             
            Most useful for:
             
            If you are a hard-core traditional network engineer already managing and monitoring your infrastructure with the CLI, this book will help you make the shift to a more efficient and more productive management and operation.
             
            If you fall into the group above, you don\u2019t need any previous knowledge in software development or programming.

            The book includes the history of SDN, how software was used to forward and route packets in networks, how an enterprise will benefit from SDN or not, how SDN works, the OpenFlow specification, SDN in data centers, SDN applications, NETCONF and much more.
             
            If you are a network designer or architect, this book will help you understand and explain to top-management the benefits or risks of integrating the SDN model in your existing network environment.
             
            Most useful for:

            CCNA 200-301 Official Cert Guide Library
             
            As mentioned at the very beginning of this article, I decided to include also books related to vendor-specific exams.
             
            Since most of the people visiting this website are Cisco professionals or people interested to pass Cisco exams, I couldn\u2019t ignore one of the most popular and useful networking certification which is Cisco CCNA.
             
            The theory and knowledge required for the newest CCNA 200-301 exam is covered fully in this comprehensive library which actually includes two books:
             
               
            • CCNA 200-301 Official Cert Guide, Volume 1
              •  
            • CCNA 200-301 Official Cert Guide, Volume 2
              •  
             
            Instead of paying double the money to buy the two books above separately, you can buy this value-priced Package Library.
             
            Most useful for:
             
            This is a Cisco-approved self-study resource for people preparing for the Cisco CCNA 200-301 exam. Along the way in studying these books, you will learn key fundamental networking concepts which will be helpful in your whole career as network engineer.
             
            Please note that this library is very detailed and can be overwhelming for total beginners in networking.

            Last but not least is my own Practical Lab Guide which comes as PDF electronic Lab Book and includes also 42 downloadable Packet Tracer labs based on the official CCNA 200-301 Cisco exam blueprint.
             
            I admit that the above Lab Book alone will not help you pass the exam by itself. It is however a great companion resource with practical labs which should be used together with other material such as the Cisco Cert Library mentioned above.
             
            If you want an affordable Lab preparation guide for the practical aspects of the CCNA exam, then my Lab Guide Book here will be very helpful, even for people that just want a refreshing in fundamental practical Cisco networking concepts.

            This socket option tells the kernel that even if this port is busy (in the TIME_WAIT state), go ahead and reuse it anyway. If it is busy, but with another state, you will still get an address already in use error. It is useful if your server has been shut down, and then restarted right away while sockets are still active on its port. You should be aware that if any unexpected data comes in, it may confuse your server, but while this is possible, it is not likely.

                    In iOS, a developer can use identifierForVendor, which is related to the bundle ID: the moment you change a bundle ID, the method will return a different value. When the app is ran for the first time, make sure you store the value returned by identifierForVendor to the KeyChain, so that changes to it can be detected at an early stage.

                    In Android, the developer can use Settings.Secure.ANDROID_ID till Android 8.0 (API level 26) to identify an application instance. Note that starting at Android 8.0 (API level 26), ANDROID_ID is no longer a device unique ID. Instead, it becomes scoped by the combination of app signing key, user and device. So validating ANDROID_ID for device blocking could be tricky for these Android versions. Because if an app changes its signing key, the ANDROID_ID will change and it won't be able to recognize old users devices. Therefore, it's better to store the ANDROID_IDencrypted and privately in a private a shared preferences file using a randomly generated key from the AndroidKeyStore and preferably AES_GCM encryption. The moment the app signature changes, the application can check for a delta and register the new ANDROID_ID. The moment this new ID changes without a new application signing key, it should indicate that something else is wrong.

                    Next, the device binding can be extended by signing requests with a key stored in the Keychain for iOS and in the KeyStore in Android can reassure strong device binding.

                    As an application developer you\u2019re armed with this knowledge about the internals of storage engines, you are in a much better position to know which tool is best suited for your particular application. If you need to adjust a database\u2019s tuning parameters, this understanding allows you to imagine what effect a higher or a lower value may have. Although this chapter couldn\u2019t make you an expert in tuning any one particular storage engine, it has hopefully equipped you with enough vocabulary and ideas that you can make sense of the documentation for the database of your choice.

                    In my limited experience I\u2019ve dealt with long-lived network partitions in a single data center (DC), PDU failures, switch failures, accidental power cycles of whole racks, whole-DC backbone failures, whole-DC power failures, and a hypoglycemic driver smashing his Ford pickup truck into a DC\u2019s HVAC system. And I\u2019m not even an ops guy.

                    It helps in analyzing gravitation to consider a situation where gravity is mocked up by acceleration. Focus attention on a region so far from any attracting matter, and so free of disturbance, that spacetime there can be consider to be flat and to have Lorentz geometry. .... When spacetime is flat, move however one will, special relativity can handle the job.
