As I’d mentioned, the problem is not with the first printing, when our usual press run ranges from 7,000 to 15,000 copies, but with subsequent printings of a many of our titles. In many cases, a few years after a title’s initial publication, a three- to five-year supply can be as low as 500 copies. The cost to set up the book (called “make-ready” in the industry) is so high that the printing/binding cost per book is far more than most readers would be willing to pay. To “break even” on some of these titles, we’d have to charge $100 or more in bookstores, which would decrease sales even further. As it is, we subsidize those volumes with donations and with sales of other books.

Are protected members/fields really that bad? No. They are way, way worse. As soon as a member is more accessible than private, you are making guarantees to other classes about how that member will behave. Since a field is totally uncontrolled, putting it "out in the wild" opens your class and classes that inherit from or interact with your class to higher bug risk. There is no way to know when a field changes, no way to control who or what changes it. If now, or at some point in the future, any of your code ever depends on a field some certain value, you now have to add validity checks and fallback logic in case it's not the expected value - every place you use it. That's a huge amount of wasted effort when you could've just made it a damn property instead ;) The best way to share information with deriving classes is the read-only property: protected object MyProperty { get; } If you absolutely have to make it read/write, don't. If you really, really have to make it read-write, rethink your design. If you still need it to be read-write, apologize to your colleagues and don't do it again :) A lot of developers believe - and will tell you - that this is overly strict. And it's true that you can get by just fine without being this strict. But taking this approach will help you go from just getting by to remarkably robust software. You'll spend far less time fixing bugs.

Another point is that properties are good in that you can place breakpoints in them to capture getting/setting events and find out where they come from.

I just wanted to tweak Java's BufferedReader to handle custom line delimiters. Thanks to private fields I have to clone the entire class rather than simply extending it and overriding readLine().

I'm not saying never mark methods private. I'm saying the better rule of thumb is to "make methods protected unless there's a good reason not to".

Marking methods protected by default is a mitigation for one of the major issues in modern SW development: failure of imagination.

The old wisdom "mark it private unless you have a good reason not to" made sense in days when it was written, before open source dominated the developer library space and VCS/dependency mgmt. became hyper collaborative thanks to Github, Maven, etc. Back then there was also money to be made by constraining the way(s) in which a library could be utilized. I spent probably the first 8 or 9 years of my career strictly adhering to this "best practice". Today, I believe it to be bad advice. Sometimes there's a reasonable argument to mark a method private, or a class final but it's exceedingly rare, and even then it's probably not improving anything.

3. Is THE BOOK TRUE, IN WHOLE OR PART?

The answer lies in an important and helpful rule of reading that is generally overlooked.That rule is simply this: In tackling a difficult book for the firsttime, read it through without ever stopping to look up orponder the things you do not understand right away.

I'm afraid you missed the joke ;-) While you believe spaces are required on both sides of an em dash, there is no consensus on this point. For example, most (but not all) American authorities say /no/ spaces should be used. That's the joke. In writing a line about "only one way to do it", I used a device (em dash) for which at least two ways to do it (with spaces, without spaces) are commonly used, neither of which is obvious -- and deliberately picked a third way just to rub it in. This will never change ;-)

Note: For keyword parameters, use @param, not @option.

It is important in your summary that you make connections between the key ideas in the article.

unevaluatedProperties is like additionalProperties, except that it can "see through" $ref and "see inside" allOf, anyOf, oneOf, if, then, else

I'm not sure if there's a reason why additionalProperties only looks at the sibling-level when checking allowed properties but IMHO this should be changed.

It's unfortunate that additionalProperties only takes the immediate, sibling-level properties into account

additionalProperties applies to all properties that are not accounted-for by properties or patternProperties in the immediate schema.

additionalProperties here applies to all properties, because there is no sibling-level properties entry - the one inside allOf does not count.

What I want is to use "additionalProperties: false" to validate a union of schemas, but it seems it isn't possible. I already tried with sevaral different combination, but I didn't make it works.

additionalProperties: false works on it, but not along with allOf, because only validate one schema or another.

Oh, my goodness. It's kind of scary looking, actually.

Update API usage of the view helpers by changing javascript_packs_with_chunks_tag and stylesheet_packs_with_chunks_tag to javascript_pack_tag and stylesheet_pack_tag. Ensure that your layouts and views will only have at most one call to javascript_pack_tag or stylesheet_pack_tag. You can now pass multiple bundles to these view helper methods.

How to Make a React Progressive Web Application (PWA)Eugene VolkovFrontend DeveloperKate KikidzhanCloud & SaaS Product ResearcherReactJavaScriptPWAHomeBlogDevelopmentHow to Make a React Progressive Web Application (PWA)Oct 7, 202021 min readThe early bird catches the worm. But the situation was not so favourable back in 2007 when Steve Jobs proposed the idea of web applications to be the model for iPhone Apps. Back then, the tech community was not yet ready to bring a huge interest in web apps. But since 2015, tech giants like Google and Microsoft have been preparing the tech ground for progressive web apps (or simply – PWAs). And now, PWA became a must-have technology for both giant corporations and small startups. Twitter, Starbucks, Google, and Aliexpress use progressive web apps to boost their online presence. At Codica, we have been helping our customers to develop their businesses by building robust PWA for our customers since 2015. That is why we have created this comprehensive guide on how to create a PWA with React. Also, you will see the most prominent progressive web app examples.

@7alhashmi: Yes, e.g. the 100 comes from the feature_values table

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.

I just wanted to point out that the syntax is not supported by the POSIX standard and thus won't universally work in /bin/sh scripts (many people erroneously use bash syntax in /bin/sh scripts)

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.

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

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.

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.

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.
