    1. "Although in the United States it is common to use the term multiculturalism to refer to both liberal forms of multiculturalism and to describe critical multicultural pedagogies, in Canada, Great Britain, Australia, and other areas,anti-racism refers to those enactments of multiculturalism grounded in critical theory and pedagogy. The term anti-racism makes a greater distinction, in my opinion, between the liberal and critical paradigms of multiculturalism, and is one of the reasons I find the anti-racism literature useful for analyzing multiculturalism in music education."

    1. However, the cookie containing the CSRF-TOKEN is only used by the client to set the X-XSRF-TOKEN header. So passing a compromised CSRF-TOKEN cookie to the Rails app won't have any negative effect.
    1. Your attempt should work. There is a mismatch in column name in your query though. The query uses col2 but the table is defined with col1.

      I would actually lean towards making this a comment, at least the typo fix part. But if you remove the typo fix part, all that's left is "should work", which I guess should be a comment too since it's too short to be an answer.

    1. But, supposing all these conjectures to be false, you cannot contest the inestimable benefit which I shall confer on all mankind to the last generation, by discovering a passage near the pole to those countries, to reach which at present so many months are requisite; or by ascertaining the secret of the magnet, which, if at all possible, can only be effected by an undertaking such as mine.

      Finally (in this second paragraph), we again have insight into the political and scientific issues of the day: the search for the famed "Northwest Passage" (big, big deal) and the awareness of a major source of danger for polar navigation: the distortion produced in magnetic equipment as one came nearer to the source, at the pole.

      It is obvious, is it not?, that most people are motivated by social goods: fame, power, money, and prestige. Because that is the world we live in.

      It's all about the Benjamins! Then and now!

    1. Social media is the biggest business industry with the most number of consumers and revenue generation in the world. And the reason is that social media is connected to every other industry now. It is where all the people come to chill, work, sell, buy, and have a good time.
    1. Events AAA and BBB are mutually exclusive (cannot both occur at once) if they have no elements in common.

      Events \(A\) and \(B\) are mutually exclusive (cannot both occur at once) if they have no elements in common.


      Events \(A\) and \(B\) are mutually exclusive if: $$P(A∩B)=0$$

    2. The complement of an event AAA in a sample space SSS, denoted AcAcA^c, is the collection of all outcomes in SSS that are not elements of the set AAA. It corresponds to negating any description in words of the event AAA.

      The complement of an event \(A\) in a sample space \(S\), denoted \(A^c\), is the collection of all outcomes in \(S\) that are not elements of the set \(A\). It corresponds to negating any description in words of the event \(A\).


      The complement of an event \(A\) consists of all outcomes of the experiment that do not result in event \(A\).

      Complement formula:

      $$P(A^c)=1-P(A)$$

    1. “Who cares? Let’s just go with the style-guide” — to which my response is that caring about the details is in the heart of much of our doings. Yes, this is not a major issue; def self.method is not even a code smell. Actually, that whole debate is on the verge of being incidental. Yet the learning process and the gained knowledge involved in understanding each choice is alone worth the discussion. Furthermore, I believe that the class << self notation echoes a better, more stable understanding of Ruby and Object Orientation in Ruby. Lastly, remember that style-guides may change or be altered (carefully, though!).

    1. Building an EHR system: Definition, Benefits, Problems, and Examples

      Are you spending more time finding patient information in a variety of disconnected systems than you are actually seeing your patients? In the end, does everything still boil down to a note nobody can ever read because it’s handwritten by a doctor? Oh, the dreaded paper medical records. They aren’t just difficult to read and analyze.If you twant to khow moreabout to build an EHR system, you’re in the right place. In this post, we talk about how doctors feel about electronic health records and what it takes to create a successful EHR system. We also lay out the differences between EHRs, EMRs, and PHRs, show examples of the best EHRs, and go deep into key features of an EHR system

    1. Whenever majorities trample upon the rights of minorities—when men are denied even the privilege of having their causes of complaint examined into—when measures, which they deem for their relief, are rejected by the despotism of a silent majority at a second reading—when such become the rules of our legislation, the Congress of this Union will no longer justly represent a republican people.
    1. Occasionally, like with search engines, #2 occurs because the incumbents gain massive economies of scale (classic Microeconomics), where by virtue of their being large, the cost to produce each incremental good or service at scale becomes much lower.
    1. Better yet, send them a link to this page to help them understand why and how to make an example app:
    2. An example app is an application that is designed to reproduce a bug or demonstrate an issue.
    3. Before a bug can be fixed, it has to be understood and reproduced. For every issue, a maintainer gets, they have to decipher what was supposed to happen and then spend minutes or hours piecing together their reproduction. Usually, they can’t get it right, so they have to ask for clarification. This back-and-forth process takes lots of energy and wastes everyone’s time. Instead, it’s better to provide an example app from the beginning. At the end of the day, would you rather maintainers spend their time making example apps or fixing issues?
    1. There are myriads of platformers around, it's an oversaturated market, and just like industrial designer Karim Rashid said about there being no excuse by this point to make an uncomfortable chair, there's no excuse by this point to make a boring patformer.

    1. If you are a fresher developer or an aspirant, you must be working hard practicing it. That's really important, and you must continue with your effort. However, we would like to lessen it as much as we can by providing an essential yet comprehensive guide.

      Whether you are planning to make an app locker for yourself or to make money or you are exploring how to create an app locker for practice, we have an excellent guide here to help you make a practical locker with password protected.

    1. Trailblazer extends the conventional MVC stack in Rails. Keep in mind that adding layers doesn't necessarily mean adding more code and complexity. The opposite is the case: Controller, view and model become lean endpoints for HTTP, rendering and persistence. Redundant code gets eliminated by putting very little application code into the right layer.
    2. While Trailblazer offers you abstraction layers for all aspects of Ruby On Rails, it does not missionize you. Wherever you want, you may fall back to the "Rails Way" with fat models, monolithic controllers, global helpers, etc. This is not a bad thing, but allows you to step-wise introduce Trailblazer's encapsulation in your app without having to rewrite it.
    3. Trailblazer is no "complex web of objects and indirection". It solves many problems that have been around for years with a cleanly layered architecture.
    1. multiple learned and generalized affectional responses are formed.

      Love can be instinctual but is it a learned behavior if the affectional response is towards someone that you share at least one intimate moment?

    1. By going through the above statistics, you would have gotten a confidence boost and additional motivation to develop your app. Now you know that the mammoth task of building an online app from scratch is equally rewarding for the efforts invested.

      So you have decided to build a mobile app for your business! But you don’t know how to create an app from scratch. Don’t worry. By the end of this article, you’ll be aware of the entire process.

    1. In object-oriented programming, information hiding (by way of nesting of types) reduces software development risk by shifting the code's dependency on an uncertain implementation (design decision) onto a well-defined interface. Clients of the interface perform operations purely through it so if the implementation changes, the clients do not have to change.
    1. The more important point comes from a program design perspective. Here, "programming to an interface" means focusing your design on what the code is doing, not how it does it. This is a vital distinction that pushes your design towards correctness and flexibility.
    2. My understanding of "programming to an interface" is different than what the question or the other answers suggest. Which is not to say that my understanding is correct, or that the things in the other answers aren't good ideas, just that they're not what I think of when I hear that term.
    3. Programming to an interface means that when you are presented with some programming interface (be it a class library, a set of functions, a network protocol or anything else) that you keep to using only things guaranteed by the interface. You may have knowledge about the underlying implementation (you may have written it), but you should not ever use that knowledge.
    4. If the program was important enough, Microsoft might actually go ahead and add some hack to their implementation so the the program would continue to work, but the cost of that is increased complexity (with all the ensuing problems) of the Windows code. It also makes life extra-hard for the Wine people, because they try to implement the WinAPI as well, but they can only refer to the documentation for how to do this, which leads to many programs not working as they should because they (accidentally or intentionally) rely on some implementation detail.
    5. Abstract myself from the how it does and get focus on what to do.
    6. Say you have software to keep track of your grocery list. In the 80's, this software would work against a command line and some flat files on floppy disk. Then you got a UI. Then you maybe put the list in the database. Later on it maybe moved to the cloud or mobile phones or facebook integration. If you designed your code specifically around the implementation (floppy disks and command lines) you would be ill-prepared for changes. If you designed your code around the interface (manipulating a grocery list) then the implementation is free to change.
    7. It's more like providing an Employee object rather than the set of linked tables you use to store an Employee record. Or providing an interface to iterate through songs, and not caring if those songs are shuffled, or on a CD, or streaming from the internet. They're just a sequence of songs.
    1. Flexbox's strength is in its content-driven model. It doesn't need to know the content up-front. You can distribute items based on their content, allow boxes to wrap which is really handy for responsive design, you can even control the distribution of negative space separately to positive space.
    1. There is one situation where iframes are (almost) required: when the contents of the iframe is in a different domain, and you have to perform authentication or check cookies that are bound to that domain. It actually prevents security problems instead of creating them. For example, if you're writing a kind of plugin that can be used on any website, but the plugin has to authenticate on another domain, you could create a seamless iframe that runs and authenticates on the external domain.
    1. I normally try to figure out if that's a good solution for the problem before resorting to iframes. Sometimes, however, an iframe just does the job better. It maintains its own browser history, helps you segregate CSS styles if that's an issue with the content you're loading in.

    1. Ubuntu also supports ‘snap’ packages which are more suited for third-party applications and tools which evolve at their own speed, independently of Ubuntu. If you want to install a high-profile app like Skype or a toolchain like the latest version of Golang, you probably want the snap because it will give you fresher versions and more control of the specific major versions you want to track.
    1. Are you exploring how to create an app from scratch? But have no idea what you actually need and how to execute this idea?

      How to build an application from scratch is the fundamental question that every vendor, business owner, and startup keeps asking when they are planning a new venture.

    1. I can’t promise I’m explaining this 100% accurately, but the way I understand it, the minimum width of a grid column is auto.

    1. I wouldn't use Flutter for web, mobile is good though.
    2. It's super promising for web apps, just maybe not for web pages. I went from React to Svelte to Flutter for my current app project, and every step felt like a major upgrade.Flutter provides the best developer experience bar none, and I think it also has the potential to provide the best user experience. But probably only for PWAs, which users are likely to install anyway. Or other self-contained experiences, like Facebook games. It does have some Flash vibes, but is far more suitable for proper app development than Flash ever was while still feeling more like a normal website to the average user. It won't be the right choice for everything, but I believe it will be for a lot of things.
    1. obviously it's too late, but it's a good practice to keep the 3rd party dependencies mirrored in your own infrastructure :) There is NO GUARANTEE that even a huge site (like launchpad for downloading DEBs) won't go down over a period of time.

    1. Some apps are free to download while some charge money. This is the simplest revenue model that you can go with. Create an exceptional app and charge a one-time fee or a yearly subscription for the app

      There are several ways to monetize an app. It all depends on the financial conditions and the general mindset of your target audience. By studying your audience, you’ll find the best way to make money from your app idea.

    1. To silence circular dependencies warnings for let's say moment library use: // rollup.config.js import path from 'path' const onwarn = warning => { // Silence circular dependency warning for moment package if ( warning.code === 'CIRCULAR_DEPENDENCY' && !warning.importer.indexOf(path.normalize('node_modules/moment/src/lib/')) ) { return } console.warn(`(!) ${warning.message}`) }
    1. Alfred Korzybski remarked that "the map is not the territory" and that "the word is not the thing", encapsulating his view that an abstraction derived from something, or a reaction to it, is not the thing itself.
    2. The map–territory relation describes the relationship between an object and a representation of that object, as in the relation between a geographical territory and a map of it.

    1. But because it is espoused by so many leading members of the JavaScript community, scrutiny is all too rarely applied.
    2. It’s written by Sindre Sorhus, whose npm profile is enough to make all but the most prolific developer feel wholly inadequate, and so carries with it a degree of authority.
    1. Svelte will not offer a generic way to support style customizing via contextual class overrides (as we'd do it in plain HTML). Instead we'll invent something new that is entirely different. If a child component is provided and does not anticipate some contextual usage scenario (style wise) you'd need to copy it or hack around that via :global hacks.
    1. Now of course we know how React handles this conflict: it takes the new nodes in your virtual DOM tree — the waters in your flowing river — and maps them onto existing nodes in the DOM. In other words React is a functional abstraction over a decidedly non-functional substrate.

      To me this is a warning sign, because in my experience, the bigger the gap between an abstraction and the thing it abstracts, the more likely you are to suffer what programmers like to call ‘impedance mismatches’, and I think we do experience that in React.

      If you have one shot at developing your best social media app like Instagram, you better be sure that you are in the right direction.

    1. "When an OP rejects your edit, please do not edit it back in!" Correspondingly, when a user repeatedly does try to edit, understand that something in your framing isn't working right, and you should reconsider it.
    2. I honestly don't know what you find unclear about this question. I think you initially misread. I edited out your title change because it wasn't what I'd intended and it misled others. I edited in two more sections to clarify. The last section makes it as clear as I can: A single question provokes 1 of 3 responses (not necessarily answers). To chose between them I need to understand acceptable scope of both question and answers. Yes this topic is a muddy one, that's why I'm asking! I want others to help me clarify the unclear!
