• 寫實驗紀錄或工作日誌的重要性 – Albert Huang – Medium
  • 每天花一點時間寫可以為自己之後省下不少時間呢，要查找一些相關資訊也會方便許多，之前的作法就是每天在相關的 issue 留下本日的進度，也方便自己隔天工作的時候可以快速進入狀況。
  • 聽起來很簡單，但做起來不那麼簡單，每天要下班之前得花一段時間來整理並確認今天到底做了哪些事，一忙起來有時候就會無法做到。

• Deploying from Travis-CI to Google Container Engine | blog

  • Travis-ci is a great CI tool. In comparison to other solutions, it has the advantage of being free for Open Source projects and is well documented. This is why I’ve been using it for a while and more recently with regexrace, a project hosted in Google Container Engine cluster.

• Continuous Delivery in a microservice infrastructure with Google Container Engine, Docker and…

  • Nowadays Continuous Integration (CI) has become a de facto standard for modern tech companies and startups. There are several options of how you can setup your perfect CI environment, from using your own Jenkins cluster to third-party services like Travis or CircleCI.

• Why Order By With Limit and Offset is Slow - Faster Pagination in Mysql

  • Queries with LIMITs and OFFSETs are common in application that require pagination and in some cases might work well for a while. In many cases though, they become slow and painful once the OFFSET has a high value. Well, in most cases, low offset queries are not slow.

• Why Good People Leave Large Tech Companies – ThinkGrowth.org

  • I was visiting with an ex-student who’s now the CFO of a large public tech company. The company is still one of the hottest places to work in tech. They make hardware with a large part of their innovation in embedded software and services.

  • 後來還是覺得得先進這些大公司累積一些經驗後，才有本錢自己出去闖啊。

• S.O.L.I.D: The First 5 Principles of Object Oriented Design ― Scotch

  • These principles, when combined together, make it easy for a programmer to develop software that are easy to maintain and extend. They also make it easy for developers to avoid code smells, easily refactor code, and are also a part of the agile or adaptive software development.

  • 這篇很清楚的介紹了 OOP 裡頭會提到的 SOLID 各自代表什麼意思，也有給出實際程式碼的例子，排版也很乾淨舒服。
  • 仔細想想大學修 OOP 的時候好像根本沒提到這個，只是在學 C++，修軟體工程的時候好像也只有提到 KISS。出來工作後也看到很多物件導向的程式碼沒照這個原則走，自己其實也沒有很嚴格遵守，現在看起來，如果都可以遵守的話，程式碼一定會好改不少吧，期許自己之後在寫物件導向有關的程式碼的時候可以謹記這 5 個原則。
  • SOLID
    • S - Single-responsiblity principle
      • A class should have one and only one reason to change, meaning that a class should have only one job.
    • O - Open-closed principle
      • Objects or entities should be open for extension, but closed for modification
    • L - Liskov substitution principle
      • Let q(x) be a property provable about objects of x of type T. Then q(y) should be provable for objects y of type S where S is a subtype of T.
    • I - Interface segregation principle
      • A client should never be forced to implement an interface that it doesn't use or clients shouldn't be forced to depend on methods they do not use.
    • D - Dependency Inversion Principle
      • Entities must depend on abstractions not on concretions. It states that the high level module must not depend on the low level module, but they should depend on abstractions.

• Find Instructions Hidden In Your CPU | Hackaday

  • There was a time when owning a computer meant you probably knew most or all of the instructions it could execute. Your modern PC, though, has a lot of instructions, many of them meant for specialized operating system, encryption, or digital signal processing features.

  • The sandsifter audits x86 processors for hidden instructions and hardware bugs, by systematically generating machine code to search through a processor's instruction set, and monitoring execution for anomalies.
