    1. Formats for Disk Images Another piece of the packaging puzzle is disk image formats. There are many. Each has its own benefits and detriments, but I’m not going to get into those here. Again, this is nowhere near a comprehensive list — just something to help with getting your bearings. I’d like to comment on a couple of the formats that I’ve recently encountered. VDI – VirtualBox’s internal default disk image format is VDI. Nevertheless, this is not what is used by Vagrant boxes. VMDK – One of the most common formats. VMWare’s products use various versions and variations of VMDK disk images. Several versions and variations exist, so it’s very important to understand which one you’re working with and where it can be used.
    2. Open Virtual Appliance (OVA) An OVA is an OVF file packaged together with all of its supporting files (disk images, etc.). You can read about the requirements for a valid OVA package in the OVF specification. Oftentimes people will say “an OVF” and really mean “an OVA.”
    3. File Formats for Virtual Machines Open Virtualization Format (OVF) The OVF Specification provides a means of describing the properties of a virtual system. It is XML based and has generous allowances for extensibility (with corresponding tradeoffs in actual portability). Most commonly, an OVF file is used to describe a single virtual machine or virtual appliance. It can contain information about the format of a virtual disk image file as well as a description of the virtual hardware that should be emulated to run the OS or application contained on such a disk image.
    1. Virtual machines (VMs) revolutionized the data center. With the ability to easily spin up a machine and even roll back to a working state, VMs bring a level of ease IT would never have enjoyed. Rolling back your VM is handled by way of snapshots.

      The OVF Specification provides a means of describing the properties of a virtual system. It is XML based and has generous allowances for extensibility (with corresponding tradeoffs in actual portability). Most commonly, an OVF file is used to describe a single virtual machine or virtual appliance. It can contain information about the format of a virtual disk image file as well as a description of the virtual hardware that should be emulated to run the OS or application contained on such a disk image.

      Oracle VM VirtualBox can import and export virtual machines in the following formats:

      Open Virtualization Format (OVF). This is the industry-standard format. See Section 1.14.1, “About the OVF Format”.
      
      Cloud service formats. Export to and import from cloud services such as Oracle Cloud Infrastructure is supported. See Section 1.15, “Integrating with Oracle Cloud Infrastructure”. 
      

      1.14.1. About the OVF Format

      OVF is a cross-platform standard supported by many virtualization products which enables the creation of ready-made virtual machines that can then be imported into a hypervisor such as Oracle VM VirtualBox. Oracle VM VirtualBox makes OVF import and export easy to do, using the VirtualBox Manager window or the command-line interface.

      https://www.virtualbox.org/manual/UserManual.html#ovf

      Using OVF enables packaging of virtual appliances. These are disk images, together with configuration settings that can be distributed easily. This way one can offer complete ready-to-use software packages, including OSes with applications, that need no configuration or installation except for importing into Oracle VM VirtualBox.

    1. In 1996, technology historian Jennifer S. Light compared the talk of “cyberoptimists” about virtual communities to city planners’ earlier optimistic predictions about shopping malls. As the automobile colonized U.S. cities in the 1950s, planners promised that malls would be enclosed public spaces to replace Main Streets. But as Light pointed out, the transition to suburban malls brought new inequities of access and limited the space’s functions to those that served commercial interests.

      Nice historical comparison.

    1. Yeah, "virtual attribute" seems like dated terminology to me, so conceptually just a method.
    2. I see a 'virtual attribute' as something we're forced to implement when using frameworks, ORMs and the like. Something that lets us inject our code into the path of whatever metaprogramming has been put in place for us. In a simple PORO like this, I don't see how it has meaning; it's just a method. :)

      Hmm, good point. Maybe so. Though I think I'm fine with calling it a virtual property here too. :shrug:

    3. has_sauce is a "virtual attribute", a characteristic of the model that's dependent on the underlying toppings attribute.

    1. quando até agora o domínio do virtual aplicado às nossas vidas se resumia à área do lazer (jogos de computador), e que muitas vezes é apontado como nocivo para o desenvolvimento pessoal e social.

      Acho estranho esta afirmação quando existe tanta coisa que se faz no domínio virtual, só mostra um total desconhecimento do que é trabalhar com realidades virtuais. Na área da informática já trabalhamos com servidores e máquinas virtuais à mais de 10 anos que fazem todas as tarefas dos seus irmãos reais, talvez se surpreendam quando verificarem a quantidade de coisas que se fazem com entidades virtuais. Em relação aos jogos também não servem só para o lazer. Veja-se este vídeo de James Paul Gee acerca das competências que se podem desenvolver a partir dos jogos para coisas muito simples como a resiliência em resolver problemas: Big Thinkers: James Paul Gee on Grading with Games

      It dawns on me that these sort of virtual reality-type images that have been around for ages aren't too dissimilar to how I see the world with various mnemonic techniques. They're also the closes way of potentially helping modern first world Western cultures better understand how many indigenous societies have seen the world in the past.

    1. This is not an issue related to using a virtual DOM. Plenty of non VDOM libraries have solved this. Imba and Solid come to mind.

    1. A JavaScript DOM model supporting element creation, diff computation and patch operations for efficient re-rendering
    2. virtual-dom exposes a set of objects designed for representing DOM nodes. A "Document Object Model Model" might seem like a strange term, but it is exactly that. It's a native JavaScript tree structure that represents a native DOM node tree.
    3. virtual-dom is a collection of modules designed to provide a declarative way of representing the DOM for your app. So instead of updating the DOM when your application state changes, you simply create a virtual tree or VTree, which looks like the DOM state that you want. virtual-dom will then figure out how to make the DOM look like this efficiently without recreating all of the DOM nodes.
    1. The Shadow DOM is a browser technology designed primarily for scoping variables and CSS in web components. The virtual DOM is a concept implemented by libraries in JavaScript on top of browser APIs.
    2. Since “virtual DOM” is more of a pattern than a specific technology, people sometimes say it to mean different things. In React world, the term “virtual DOM” is usually associated with React elements since they are the objects representing the user interface
    3. The virtual DOM (VDOM) is a programming concept where an ideal, or “virtual”, representation of a UI is kept in memory and synced with the “real” DOM by a library such as ReactDOM.
    1. Strategies for Virtual Learning Environments:Focusing on Teaching Presence and TeachingImmediacy

      Through a literature review of 50 articles published between 2003-2014, the authors explored aspects of online learning (teacher presence, teacher immediacy) that impact learner interest and motivation in the online environment. Recognizing that these aspects are key, the authors explore various approaches to retention the virtual setting. The multifaceted role of the instructor is reviewed as well as virtual facilitation strategies. The literature search revealed a positive correlation between teaching presence, teaching immediacy, and learner engagement and motivation. 6/10

    1. React creates a virtual DOM. When state changes in a component it firstly runs a “diffing” algorithm, which identifies what has changed in the virtual DOM. The second step is reconciliation, where it updates the DOM with the results of diff.The HTML DOM is always tree-structured — which is allowed by the structure of HTML document. The DOM trees are huge nowadays because of large apps. Since we are more and more pushed towards dynamic web apps (Single Page Applications — SPAs), we need to modify the DOM tree incessantly and a lot. And this is a real performance and development pain.The Virtual DOM is an abstraction of the HTML DOM. It is lightweight and detached from the browser-specific implementation details. It is not invented by React but it uses it and provides it for free. ReactElements lives in the virtual DOM. They make the basic nodes here. Once we defined the elements, ReactElements can be render into the "real" DOM.Whenever a ReactComponent is changing the state, diff algorithm in React runs and identifies what has changed. And then it updates the DOM with the results of diff. The point is - it’s done faster than it would be in the regular DOM.

      React creates a virtual DOM and every time the state of a component changes, it runs a diff algorithm on the virtual DOM. If something needs to be changed, it changes only this part in the HTML DOM. This is faster than the default of updating the entire HTML DOM any time something changes.

    1. When in need of help, students reread directions, checkwith Home-Group members (3-4 students who are inschool or at home on the same days), check the digitalPeer Expert Board, and then put their name on the digitalHelp Board

      This is a fantastic idea for building community.

      Facilitate in Google? Allow edits on a Canvas page? What about multiple editors?

      • Google Slides parking lot embedded on the homepage
        • Each student has a slide they edit
        • General questions slide for help requests
    2. review teacher notes and the schedule theydesigned for themselves for the week,

      Students are dictating the pace and the content they're working on. The teacher is helping to curate and interpret those materials as students work through the idea.

    3. Curate an instructional plan forstudents, whether at home orschool, that will addresscognitive, learning style, andcultural differences.

      I don't remember where it was, but someone suggested a 5:1 prep:teach time ratio. Spend far more time prepping (researching, finding resources, etc) than you do actually teaching students verbally so you have several items to incorporate or fall back on.

    4. BenchmarkDiscussion

      What is a Benchmark Discussion? Why is it capitalized?

    5. Students continue working ondifferentiated learning activities.(Remote only? Hold discussionswith half of the class at a time.)

      Sounds like great use of a fishbowl model.

    6. socially-distanced in-school students andat-home students can join

      Use the tools that are available to make the in-person material as accessible as possible to the at home students.

      • iPad as a document camera
      • AirServer to the board, share screen to Meet

      Repeat the sessions on A/B days? One day per week for these sessions?

    7. Students access an Activity List

      Weekly planning is critical. This helps the teacher provide consistent, supportive instruction and it helps the student regulate their work.

      Having minimesters this term will help students focus.

    8. indicate they arepresent

      What are some simple ways to indicate they're present?

      • Google Form with email automatically collected?
      • Canvas survey with a simple get to know you question?

      Something independent that can build self-regulation skills and habits.

    9. I recommend a cloud-baseddocument where students can post their thoughts or comments (in-school and at-home students) so thatthe teacher can follow the discussion

      Backchanneling - or doing something like a remote fishbowl discussion - can help facilitate the physical gap for students at home vs in class.

      • How can we explore bringing in home/school students at the same time? Try with the ambassadors?
    10. Time with the teacher “live” shifts to these Small-Group, Mini-Lessons and live discussions whereteachers can engage students in collectively grappling with content.

      Time is spent talking with one another, not a teacher talking at a group of students.

      Separate yourself out of time constraints by providing familiar instruction materials (ie, video) ahead of the small group meeting so the group time is as effective and focused as possible.

    11. Whole-class lessons across video, sometimes called “live streaming,” are not effective -- I won’teven sugar-coat that

      There are too many unknown factors involved in expecting every student, in vastly different home situations, to engage equally in a given situation.

    12. Teachers need to avoid reserving in-school days for lessons andteacher talk, thus, robbing students of the socialization skills they are craving

      When you're together, it's time to listen to what students are saying rather than talking at them even more.

      see Dan Meyer: https://blog.mrmeyer.com/2020/but-artichokes-arent-pinecones-what-do-you-do-with-wrong-answers/

    13. We cannot afford to depend on in-school time for lessons and at-home time only forpractice.

      This is a remnant of the old model of schooling which needs to be foregone in favor of better models, more suited to flexible learning environments.

    14. The key to a successful hybrid learning environment is implementing structures and strategiesthat work as well at home as they do in school, such that learning continues whether at home orat school -- no need for a change in methods with a change in setting

      These should be based on skills students already have or which can be developed independently (or with limited, in person support).
