In this blog, we will see how one can build a fitness app that can be highly accepted by its users and the revenue model. Let’s have a look!

Because constants in Ruby aren't meant to be changed, Ruby discourages you from assigning to them in parts of code which might get executed more than once, such as inside methods.

The implicit dependencies between different versions of different services were not expressed anywhere, which led to various problems in building, continuous integration, and, notably, repeatable builds.

You may want to try putting the one-liner (everything in the single quotes) in an actual script, with a bash shebang line. I think filter-branch is probably trying to run this in sh, not bash.

Refactor ruthlessly. Rewrite bravely.

This is a copy of the "AMD" document in the repo, kept here to maintain historical links. If this document differs from the one in the repo, the repo version is the correct one.

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.

Fexeel ba kër gi bañ ñàkk alkol.

now that I realize how easy it is to just manually include this in my app: <%= javascript_include_tag 'xray', nonce: true if Rails.env.development? %> I regret even wasting my time getting it to automatically look for and add a nonce to the auto-injected xray.js script

Keep in mind that third party code with references to other files also processed by the asset Pipeline (images, stylesheets, etc.), will need to be rewritten to use helpers like asset_path.

But so far everything brought up has just been about the relative advantages of checked exceptions, and that issue is closed. We won't do it.

Enforces better architecture

In other words, once you've used Maybe you cannot hit nil with a missing method. This is remarkable because even &. doesn't save you from omitting || "No state" at the end of the computation. Basically, that's what they call "Type Safety".

The new 2.1 version comes with a few necessary but reasonable changes in method signatures. As painful as that might sound to your Rails-spoiled ears, we preferred to fix design mistakes now before dragging them on forever.

The new call API is much more consistent and takes away another thing we kept explaining to new users - an indicator for a flawed API.

Trust me, I thought a lot about #validate and its semantics, and I am gonna make it even more "SRP" by making Form#errors and #valid? semi-public. All that happens via #validate reducing the possible wrong usage for users.

I've reproduced, in a very simple way, what I would like it to do: https://svelte.dev/repl/2b0b7837e3ba44b5aba8d7e774094bb4?version=3.19.1

The only solution that I can see is to ensure that each user gets their own set of stores for each server-rendered page. We can achieve this with the context API, and expose the stores like so: <script> import { stores } from '@sapper/app'; const { page, preloading, session } = stores(); </script> Calling stores() outside component initialisation would be an error.

This would be cumbersome, and would encourage developers to populate stores from inside components, which makes accidental data leakage significantly more likely.

which makes it much harder to accidentally keep logged-in state visible after a client-side logout

I changed if (value) { to if (typeof value !== "undefined") { as it was skipping some keys

Best Video Chat Apps of 2020: Niche Leaders and User Favorites

If you want a reference to the global object that works in any context, you can read this from a directly-called function. const global = (function() {return this})();. This evaluates to window in the browser, self in a service worker and global in nodejs.

You already have the reason: to raise distinction

So I assume the main reason is for distinction from regular text.

Svelte Material UI 2.0 (Typescript + MDC 7+)

But seriously, give snowpack a read to understand the benefits of leaning on standard esm imports, allowing you to avoid a bundling process entirely.

I don't need to support non-esm browsers for most projects and I really like the idea of a super light build process. By removing the complexity of configuration and the overhead of bundling, svelvet makes the development process an optimal experience for myself and hopefully others

It replaces heavier, more complex bundlers like webpack or Parcel in your development workflow.

The ultimate goal of the Open Library is to make all the published works of humankind available to everyone in the world. While large in scope and ambition, this goal is within our grasp.

There was a major refactoring in the resolver (https://github.com/webpack/enhanced-resolve). This means the resolving option were changed too. Mostly simplification and changes that make it more unlikely to configure it incorrectly.

However, this construct is not completely equivalent to if ... fi in the general case.

How to Create a Messaging Application from Scratch

Looking at all those bearing, heading, orientation, navigation, position, direction, etc. I think we have a bigger problem here. Someone has decided how to use tag (e.g. orientation is about page orientation), but there are 100 other cases. Imho, to disallow misusing there should be no "heading", but rather "html-heading", "gps-heading", "whatelse-heading", which make mistakes impossible. So yes, "heading" should go.

With Flutter, the quality of app development is such that although being a Hybrid framework, the feel is of a native app. Flutter is the brainchild of Google. Companies want to build the best app for the most number of people that they can reach. Flutter fulfills the exact requirements for the developers as well as the business owners.

In a large code base, this will result in moving imports randomly around until stuff just happens to work. Which is often only temporary, as a small refactoring or change in import statements in the future can subtly adjust the module loading order, reintroducing the problem.

If something isn't a great idea, the tools should support that approach

Looks like the problem is that debounce defaults to waiting for 0 ms ... which is completely useless!

It looks like you accidentally passed resolve() (immediately invoking the function) directly to setTimeout rather than passing a function to invoke it. So it was being resolved immediately instead of after a 1000 ms delay as intended.

You should not create a new debounce function on every render with: return new Promise(resolve => { debounce(() => resolve(this.getIsNameUnique(name)), 2000); }); Instead you should just wrap your whole function isNameUnique with the debounce (see my sandbox). By creating a new debounce function on every hit, it cannot 'remember' that is was called or that is will be called again. This will prevent the debouncing.

_.debounce creates a function that debounces the function that's passed into it. What your s.search function is doing is calling _.debounce all over again every time s.search is called. This creates a whole new function every time, so there's nothing to debounce.

I run s.search() by typing into an input box, and if I type gibberish very quickly, the console prints out "making search request" on every key press, so many times per second -- indicating that it hasn't been debounced at all.

they're not invoking the function that _.debounce returns

I'm okay with an overall design that allows people to plugin the parts they need in order to be able to generically support a compile-to-javascript language, but to bake in support for one singular solution because its popular is simply bad engineering.

Of all the compile-to-languages, the one that strikes me as having the least merit is JSX. It's basically a ton of added complexity for the sake of what boils down to syntax. There are no real gains in terms of language semantics in JSX.

hyperscript is more concise because it's just a function call and doesn't require a closing tag. Using it will greatly simplify your tooling chain.

This is the problem with baking in support for frameworks with special cases in the codebase. You can never support all the frameworks. :-(

When using React hooks there is no concept of onMount because the idea of only running some code on mount leads to writing non-resilient components, components that do one thing when they mount, and then don’t take prop changes into account.

How to Build a Food Delivery Website for Your Restaurant

setContext / getContext can only be used once at component init, so how do you share your API result through context? Related: how would you share those API results if the call was made outside of a Svelte component, where setContext would be even more out of the question (and the API call would arguably be better located, for separation of concerns matters)? Well, put a store in your context.

small modules allow library authors to become lazy. Why include that six-line helper function when you can do a one-line `require`?

These are all things that make your life as a library author easier.

I assume that soon developers will publish more components for svelte, and any possible class conflict is problematic. Yeah, it's rare case, but it is.

Just throwing in <div class="{$$props.class || ''} otherChildClass"></div> seems the easiest, and it'll avoid undefined classes. I feel like many aren't noticing the undefined values getting inserted in their classes.

There are work arounds, but nothing clean. I just feel like this should be functionality that should be part of the slot feature.

new style RFC

I totally get not wanting to extend the syntax. I tried doing these things and in practice it was not easy or pretty. Actions provide a much cleaner and easier way to accomplish a certain set of functionality that would be much more difficult without it.

Actions add additional functionality to elements within your component's template that may be difficult to add with other mechanisms. Examples of functionality which actions makes trivial to attach are:

If this was tied into Svelte's flow with hooks this would not be necessary since it would know when it was being removed from the DOM.

I think that we should be willing (taking the risk) to make bold changes, as long as they fit in the direction we see the community going in the long term (with Material-UI empowering it).

Can you try to delete node_modules folder and package-lock.json file.

clean node_modules

Between each step I did rm -rf node_modules package-lock.json && npm i. Just to be sure

FWIW, I would have raised it earlier if I thought it would have made a difference.

Can't upvote this enough. It is highly irritating to see language destroyed (and we wonder why kids bastardize the language..).

my point is that using "into" in such a case is just as incorrect as using "inas" would be. The fact that people make mistakes doesn't change this.

As a web designer, I hate that "log in" creates a visual space between the words. If you line up "Log In Register" - is that three links or two? This creates a Gestalt problem, meaning you have to really fiddle with spacing to get the word groupings right, without using pipe characters.

While Rails supports numbering of initializer file names for load ordering purposes, a better technique is to place any code that need to load in a specific order within the same file. This reduces file name churn, makes dependencies more explicit, and can help surface new concepts within your application.

According to our understanding of the inconsistencies, the feature was likely trying to support too many edge cases. All caching strategies have weaknesses and eventually break down if the usage is not properly scoped.

Although it can minimize the overhead of third-party tags, it also makes it trivial for anyone with credentials to add costly tags.

Instead of having a task like “write an outline of the first chapter,” you have a task like “find notes which seem relevant.” Each step feels doable. This is an executable strategy (see Executable strategy).
