    1. notebook contains an actual running Python interpreter instance that you’re fully in control of. So Jupyter can provide auto-completions, parameter lists, and context-sensitive documentation based on the actual state of your code

      Notebook makes it easier to handle dynamic Python features

    2. Mathematica didn’t really help me build anything useful, because I couldn’t distribute my code or applications to colleagues (unless they spent thousands of dollars for a Mathematica license to use it), and I couldn’t easily create web applications for people to access from the browser. In addition, I found my Mathematica code would often end up much slower and more memory hungry than code I wrote in other languages.

      Disadvantages of Mathematica:

      • memory hungry, slow code
      • expensive code
      • non-distributable license
    3. a methodology that combines a programming language with a documentation language, thereby making programs more robust, more portable, more easily maintained, and arguably more fun to write than programs that are written only in a high-level language. The main idea is to treat a program as a piece of literature, addressed to human beings rather than to a computer.

      Exploratory testing described by Donald Knuth

    4. In recent years we’ve also begun to see increasing interest in exploratory testing as an important part of the agile toolbox

      Waterfall software development ---> agile ---> exploratory testing

    5. In the 1990s, however, things started to change. Agile development became popular. People started to understand the reality that most software development is an iterative process
    6. When I began coding, around 30 years ago, waterfall software development was used nearly exclusively.
    7. Development Pros Cons

      Table comparing pros and cons of:

      • IDE/Editor
      • REPL/shell
      • Traditional notebooks (like Jupyter)
    8. Exploratory programming is based on the observation that most of us spend most of our time as coders exploring and experimenting

      In exploratory programming, we:

      • experiment with a new API to understand how it works
      • explore the behavior of an algorithm that we're developing
      • debug our code through combination of inputs
    9. This kind of “exploring” is easiest when you develop on the prompt (or REPL), or using a notebook-oriented development system like Jupyter Notebooks

      It's easier to explore the code:

      • when you develop on the prompt (or REPL)
      • in notebook-oriented system like Jupyter

      but, it's not efficient to develop in them

    10. They switch to get features like good doc lookup, good syntax highlighting, integration with unit tests, and (critically!) the ability to produce final, distributable source code files, as opposed to notebooks or REPL histories

      Things missed in Jupyter Notebooks:

      • good doc lookup
      • good syntax highlighting
      • integration with unit tests
      • ability to produce final, distributable source code files
    1. Computers can only natively store integers, so they need some way of representing decimal numbers. This representation comes with some degree of inaccuracy. That's why, more often than not, .1 + .2 != .3

      Computers make up their way to store decimal numbers

    1. esnext: source code using stage 4 features (or older), not transpiled, in ES modules. main continues to be used the same way. Its code can be generated from the untranspiled code. Most module use cases should be handleable via esnext. browser can be handled via an extended version of esnext (see next section).

    1. This article, developed by faculty members at NAU, provides research behind and practices for technology-infused professional development (PD) programs. The authors first emphasize the importance of designing professional development for teachers around how they and their students learn best. Many approaches to PD have taken a one-size-fits-all approach in which learners take a more passive role in absorbing standardized information. The authors in this article suggest the need for a more effective model, one in which teachers play an active role in learning in ways that they find most effective for them and their students. Technology can support this PD through interactive and learner-centered instruction. Rating: 9/10

    1. The text documents a year-long research project into experiential learning in teacher professional development. Teachers participated in experiential learning themselves to then begin to implement it into their own classrooms to serve their students. By and large, teachers were receptive, had misconceptions addressed, changed their practices with their colleagues and students to develop more engaging and active classrooms. Essentially, a shift from teacher-centered learning to student-centered learning was achieved in small increments by using experiential learning and reflection to facilitate teacher growth thereby creating new pathways for student learning. Given the nature of the traditional methods predominantly used, this study seems to reflect some elements of transformative learning in which teacher conventions and ideas were challenged and adjusted through heterogenous groups and personal reflection.

    1. Some of our main takeaways:CRDT literature can be relevant even if you're not creating a decentralized systemMultiplayer for a visual editor like ours wasn't as intimidating as we thoughtTaking time to research and prototype in the beginning really paid off

      Key takeaways of developing a live editing tool

    2. We had a lot of trouble until we settled on a principle to help guide us: if you undo a lot, copy something, and redo back to the present (a common operation), the document should not change. This may seem obvious but the single-player implementation of redo means “put back what I did” which may end up overwriting what other people did next if you’re not careful. This is why in Figma an undo operation modifies redo history at the time of the undo, and likewise a redo operation modifies undo history at the time of the redo

      Undo/Redo working

    3. Figma doesn’t store any properties of deleted objects on the server. That data is instead stored in the undo buffer of the client that performed the delete. If that client wants to undo the delete, then it’s also responsible for restoring all properties of the deleted objects. This helps keep long-lived documents from continuing to grow in size as they are edited

      Undo option

    4. An important consequence of this is that changes are atomic at the property value boundary. The eventually consistent value for a given property is always a value sent by one of the clients. This is why simultaneous editing of the same text value doesn’t work in Figma. If the text value is B and someone changes it to AB at the same time as someone else changes it to BC, the end result will be either AB or BC but never ABC

      Consequence of approaches like last-writer-wins

    5. Figma’s multiplayer servers keep track of the latest value that any client has sent for a given property on a given object

      No conflict:

      • two clients changing unrelated properties on the same object
      • two clients changing the same property on unrelated objects.

      Conflict:

      • two clients changing the same property on the same object (document will end up with the last value sent)
    6. Every Figma document is a tree of objects, similar to the HTML DOM. There is a single root object that represents the entire document. Underneath the root object are page objects, and underneath each page object is a hierarchy of objects representing the contents of the page. This tree is is presented in the layers panel on the left-hand side of the Figma editor.

      Structure of Figma documents

    7. Even if you have a client-server setup, CRDTs are still worth researching because they provide a well-studied, solid foundation to start with

      CRDTs are worth studying for a good foundation

    8. CRDTs are designed for decentralized systems where there is no single central authority to decide what the final state should be. There is some unavoidable performance and memory overhead with doing this. Since Figma is centralized (our server is the central authority), we can simplify our system by removing this extra overhead and benefit from a faster and leaner implementation

      CRDTs are designed for decentralized systems

    9. There are many types of CRDTs

      CRDTs have different types, such as Grow-only set and Last-writer-wins register. Check more of them here

    10. CRDTs refer to a collection of different data structures commonly used in distributed systems. All CRDTs satisfy certain mathematical properties which guarantee eventual consistency. If no more updates are made, eventually everyone accessing the data structure will see the same thing. This constraint is required for correctness; we cannot allow two clients editing the same Figma document to diverge and never converge again

      CRDTs (Conflict-free Replicated Data Types)

    11. They’re a great way of editing long text documents with low memory and performance overhead, but they are very complicated and hard to implement correctly

      Characteristics of OTs

    12. operational transforms (a.k.a. OTs), the standard multiplayer algorithm popularized by apps like Google Docs. As a startup we value the ability to ship features quickly, and OTs were unnecessarily complex for our problem space

      Operational Transforms (OT) are unnecessarily complex for problems unlike Google Docs

    13. Designers worried that live collaborative editing would result in “hovering art directors” and “design by committee” catastrophes.

      Worries of using a live collaborative editing

    14. We use a client/server architecture where Figma clients are web pages that talk with a cluster of servers over WebSockets. Our servers currently spin up a separate process for each multiplayer document which everyone editing that document connects to

      Way Figma approaches client/server architecture

    15. When a document is opened, the client starts by downloading a copy of the file. From that point on, updates to that document in both directions are synced over the WebSocket connection. Figma lets you go offline for an arbitrary amount of time and continue editing. When you come back online, the client downloads a fresh copy of the document, reapplies any offline edits on top of this latest state, and then continues syncing updates over a new WebSocket connection

      Offline editing isn't a problem, unlike the online one

    16. traditional approaches that informed ours — OTs and CRDTs

      Traditional approaches of the multiplayer technology

    17. it's important to be able to iterate quickly and experiment before committing to an approach. That's why we first created a prototype environment to test our ideas instead of working in the real codebase

      First work with a prototype, then the real codebase

    1. The Politics of Sustainability and Development

      This reading is to help you better understand the role and importance of literature review. Literature review connects us to a bigger community of scientists who study the same research topic, and helps us build up, illustrate, and develop our theory (what is happening between the IV and the DV?) and research design (how one plans to answer the RQ).

    1. When we talk about abstraction levels, we can classify the code in 3 levels: high: getAdress medium: inactiveUsers = Users.findInactives low: .split(" ")

      3 abstraction levels:

      1. high: getAdress
      2. medium: inactiveUsers = Users.findInactives
      3. low: .split(" ")

      Explanation:

      • The high level abstraction are functions that you create, like searchForsomething()
      • The medium level are methods in your object, like account.unverifyAccount
      • The low level are methods that the language provides, like map, to_downncase and so on
    2. Uncle Bob, in clean code, defends that the best order to write code is: Write unit tests. Create code that works. Refactor to clean the code.

      Best order to write code (according to Uncle Bob):

      1. Write unit tests.
      2. Create code that works.
      3. Refactor to clean the code.
    3. Sometimes it's interesting to explain some code (How many time you spend trying to figure out a regex pattern when you see one?), but, in 99% of the time, comments could be avoided.

      Generally try to avoid (avoid != forbid) comments.

      Comments:

      1. Become outdated, confusing your future self (Yesterday I lost some precious time because of an outdated comment)
      2. Could be replaced for some better named variable/function/class.
      3. They pollute the code unnecessarily.
    4. There is another maxim also that says: you must write the same code a maximum of 3 times. The third time you should consider refactoring and reducing duplication

      Avoid repeating the same code over and over

    5. decrease the switch/if/else is to use polymorphism

      It's better to avoid excessive switch/if/else statements

      example

    6. The ideal is not to mix the abstraction levels in only one function.

      Try not mixing abstraction levels inside a single function

    7. In the ideal world, they should be 1 or 2 levels of indentation

      Functions in the ideal world shouldn't be long
