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.

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.

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.

Abstract myself from the how it does and get focus on what to do.

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.

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.

We think that, although Ruby is a great language for the backend, the view should be written in languages designed for that purpose, HTML and JavaScript.

We also find it hard to agree on what good names and bad names look like, which makes it hard to know when renaming improves a name.

Our app is mostly about displaying pages of static information. We crunch a lot of data to generate a single error report page.

Honeybadger isn't a single page app, and it probably won't ever be. SPAs just don't make sense for our technical requirements.

You can write the query in this good old way to avoid error

Also there is always an option to use SQL: @items .joins(:orders) .where("orders.user_id = ? OR items.available = true", current_user.id)

but if .or() throws an error then I'm back to the bad old days of using to_sql

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.

Flexbox is for one dimensional layout (row or column). CSS grid is for two dimensional layout.

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.

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.

Usually, if you can do it without an iframe, that is a better option. I'm sure others here may have more information or more specific examples, it all comes down to the problem you are trying to solve.

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.

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.

Depending on what other component libraries you’ve used, you may be used to handling events by passing callback functions to component properties, or using a special event syntax – Svelte supports both, though one is usually more appropriate than the other depending on your situation. This post explains both ways.

I wouldn't use Flutter for web, mobile is good though.

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.

As was mentioned in the comments above, the material design spec for buttons specifies that the text should be uppercase, but you can easily override its CSS property: paper-button { text-transform: none; }

enables passive event listeners by default for some events (see list below). It basically will set { passive: true } automatically every time you declare a new event listener.

@use "@material/theme" with (  $primary: #FEDBD0,  $on-primary: #442C2E);

You could totally just write your own name and not use the name in package.json, this template is made so the users wouldn't need to think about the UMD build.

So if you need to build an app like Uber, you should know the company approaches, technology, and business processes.

If everyone did this, the repair shops would be out of business.

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.

Just coming here to voice my agreement that these warnings are annoying and exist in other libraries as well. For me this happened with svelma. I didn't write the library code, so I don't have complete control over it even though I agree there is an argument to be had around whether I should be notified anyway. In either case, these warnings should be easily disabled since libraries don't always get updated over night.

Maybe it's also a bug because every warning should be ignorable? Not sure.

I would like the compiler to add a property like canIgnore: false to the warning, if the warning cannot be disabled.

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}`) }

Adding an API for something is an endorsement of that approach.

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.

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.

More in-depth examples definitely sound like a good idea. I've seen cookbooks quite a few times already and they are always helpful.

I’d still be interested in Svelte making things easier so I’ve opened a feature request for Reactive statement cleanup functions.

Disclaimer: I’m new to Svelte so this isn’t so much a recommendation as it is a “I guess this is a way to do it 🤷‍♂️”

I pushed the build files & tested it in my environment so this should work as is.

I pushed a hotfix, based on v3.6.3 proposed by #2086 (comment) In package.json, under devDependencies, use: "svelte": "btakita/svelte#svelte-gh-2086-hotfix"

But because it is espoused by so many leading members of the JavaScript community, scrutiny is all too rarely applied.

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.

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.

The problem with working around the current limitations of Svelte style (:global, svelte:head, external styles or various wild card selectors) is that the API is uglier, bigger, harder to explain AND it loses one of the best features of Svelte IMO - contextual style encapsulation. I can understand that CSS classes are a bit uncontrollable, but this type of blocking will just push developers to work around it and create worse solutions.

This is a little confusing to describe. An example:

Even without going to that extreme, the constraint of having a single <style> can easily force component authors to resort to the kinds of classes-as-namespaces hacks that scoped styles are supposed to obviate.

"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.

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!

But it has as an external service several disadvantages which opposed the philosophy of static websites diametrically.

Some large tech behemoths could hypothetically shoulder the enormous financial burden of handling hundreds of new lawsuits if they suddenly became responsible for the random things their users say, but it would not be possible for a small nonprofit like Signal to continue to operate within the United States. Tech companies and organizations may be forced to relocate, and new startups may choose to begin in other countries instead.

A "tag" is a snippet of code that allows digital marketing teams to collect data, set cookies or integrate third-party content like social media widgets into a site.

This is it. I'm done with Page Translator, but you don't have to be. Fork the repo. Distribute the code yourself. This is now a cat-and-mouse game with Mozilla. Users will have to jump from one extension to another until language translation is a standard feature or the extension policy changes.

What I don't like is how they've killed so many useful extensions without any sane method of overriding their decisions.

I know, you don't trust Mozilla but do you also not trust the developer? I absolutely do! That is the whole point of this discussion. Mozilla doesn't trust S3.Translator or jeremiahlee but I do. They blocked page-translator for pedantic reasons. Which is why I want the option to override their decision to specifically install few extensions that I'm okay with.

Mozilla will never publicly ask users to circumvent their own blocklist. But it's their actions that are forcing people to do so.

So to me, it seems like they want to keep their users safer by... making them use Google Chrome or... exposing themselves to even greater danger by disabling the whole blocklist.

Unfortunately, loading their code from their CDN is the only way those services permit their use.

Add-ons must be self-contained and not load remote code for execution

Mozilla does not permit extensions distributed through https://addons.mozilla.org/ to load external scripts. Mozilla does allow extensions to be externally distributed, but https://addons.mozilla.org/ is how most people discover extensions. The are still concerns: Google and Microsoft do not grant permission for others to distribute their "widget" scripts. Google's and Microsoft's "widget" scripts are minified. This prevents Mozilla's reviewers from being able to easily evaluate the code that is being distributed. Mozilla can reject an extension for this. Even if an extension author self-distributes, Mozilla can request the source code for the extension and halt its distribution for the same reason.

Despite their awarded diplomas in the art of writing, you'd be surprised at how many editors and journalists in the United States make English mistakes. For instance, "an" is still often coupled with words that begin with an "H" sound, even though this is improper. I'd advise against treating material from news sources as if it were error-free or even a higher authority on grammar.

Short of a fingerprint reader, two-step verification (aka two-step authorization) may be the single best way to protect online accounts.

2-Step Verification

The word "passphrase" is used to convey the idea that a password, which is a single word, is far too short to protect you and that using a longer phrase is much better.

The typical clinical course of an epidural hematoma is an initial loss of consciousness, a lucid interval, and recurrent loss of consciousness with an ipsilateral fixed and dilated pupil. While decompression of subdural hematomas may be delayed, epidural hematomas require evacuation within 70 minutes.

BOOK 12 THE ARGUMENT The Angel Michael continues from the Flood to relate what shall succeed; then, in the mention of Abraham, comes by degrees to explain, who that Seed of the Woman shall be, which was promised Adam and Eve in the Fall; his Incarnation, Death, Resurrection, and Ascention; the state of the Church till his second Coming. Adam greatly satisfied and recomforted by these Relations and Promises descends the Hill with Michael; wakens Eve, who all this while had slept, but with gentle dreams compos'd to quietness of mind and submission. Michael in either hand leads them out of Paradise, the fiery Sword waving behind them, and the Cherubim taking thir Stations to guard the Place.

Hee with a crew, whom like Ambition joyns With him or under him to tyrannize, Marching from Eden towards the West, shall finde [ 40 ] The Plain, wherein a black bituminous gurge Boiles out from under ground, the mouth of Hell; Of Brick, and of that stuff they cast to build A Citie and Towre, whose top may reach to Heav'n; And get themselves a name, least far disperst [ 45 ] In foraign Lands thir memorie be lost, Regardless whether good or evil fame. But God who oft descends to visit men Unseen, and through thir habitations walks To mark thir doings, them beholding soon, [ 50 ] Comes down to see thir Citie, ere the Tower Obstruct Heav'n Towrs, and in derision sets Upon thir Tongues a various Spirit to rase Quite out thir Native Language, and instead To sow a jangling noise of words unknown: [ 55 ] Forthwith a hideous gabble rises loud Among the Builders; each to other calls Not understood, till hoarse, and all in rage, As mockt they storm; great laughter was in Heav'n And looking down, to see the hubbub strange [ 60 ] And hear the din; thus was the building left Ridiculous, and the work Confusion nam'd.

The point of political protest is to change the world. And yet the process matters, too.

To live in the present is not to avoid hard work or strife. Alongside the projects that occupy you in your profession, or in your political life, the telic activities that matter to you, is the atelic process of protesting injustice or doing your job. To value the process is not to flee from work or political engagement. That is why living in the present is not an abdication of ethical responsibility or a recipe for detachment.

To live in the present is not to deny the value of telic activities, of making a difference in the world. That would be a terrible mistake. Nor can we avoid engaging in such activities. But if projects are all we value, our lives become self-subversive, aimed at extinguishing the sources of meaning within them. To live in the present is to refuse the excessive investment in projects, in achievements and results, that sees no inherent value in the process.

“If you are learning, you have not at the same time learned.” When you care about telic activities, projects such as writing a report, getting married or making dinner, satisfaction is always in the future or the past. It is yet to be achieved and then it is gone. Telic activities are exhaustible; in fact, they aim at their own exhaustion. They thus exhibit a peculiar self-subversion. In valuing and so pursuing these activities, we aim to complete them, and so to expel them from our lives.

an objective set for the Sprint that can be met through the implementation of Product Backlog. It provides guidance to the Development Team on why it is building the Increment. It is created during the Sprint Planning meeting. The Sprint Goal gives the Development Team some flexibility regarding the functionality implemented within the Sprint. The selected Product Backlog items deliver one coherent function, which can be the Sprint Goal. The Sprint Goal can be any other coherence that causes the Development Team to work together rather than on separate initiatives.
