So if the network roundtrip time to your server is even 100ms, and Sliding Sync is operating infinitely quickly, you’re still going to end up showing a placeholders for a few frames

Usage of an IS is not required in order for a client application to be part of the Matrix ecosystem. However, without one clients will not be able to look up user IDs using 3PIDs

type values MUST be uniquely globally namespaced following Java’s package naming conventions, e.g. com.example.myapp.event

signing the message in the context of the graph for integrity

and shares data with the wider Matrix ecosystem by synchronising communication history with other homeservers and their clients

Managing user accounts (registration, login, logout)

Extensible user profile management (avatars, display names, etc)

Extensible user management (inviting, joining, leaving, kicking, banning) mediated by a power-level based user privilege system

The user should know precisely where their data is stored

no single points of control over conversations or the network as a whole

Sending and receiving extensible messages

across a global open network of federated servers and services

The same applies to reorganisation, whoseobject is merely to substitute superior for inferior control oradequate for inadequate control.

@chrisaldrich thank you for this detailed response about your use of Obsidian and organization for digital Zettelkasten. I am not sure if this is the current forum or discussion to ask this but I would be curious to see how you have integrated or coordinated your analog Zettelkasten and notetaking with what you describe here. I've followed your posts about the use of index cards for a long time. I'd love to see how you use the very different affordances of these environments together.

Meta-level referencing (addresses on linksthemselves) enables knowledge workers to commentupon links and otherwise reference them.

By dropping or reducing or postponing the least importantparts, we can unblock ourselves and move forward even when timeis scarce.

output.addEventListener("click", ((event) => { if (event.target == output.querySelector("a.bookmarklet")) { alert("It's not an ordinary link; you need to bookmark it");

makes your app inaccessible to users if JavaScript fails or is disabled (which happens more often than you probably think).

Build a baseline email experience for subscribers using email apps with limited support for HTML and CSS—such as Outlook and Gmail—before enhancing your email for other clients. Progressive enhancement should not create suboptimal experiences for other users.

An escalator is a great example of progressive enhancement and graceful degradation in real life. The late comedian Mitch Hedberg joked, “An escalator can never break: it can only become stairs. You should never see an Escalator Temporarily Out Of Order sign, just Escalator Temporarily Stairs. Sorry for the convenience.” Regardless of its environment, an escalator maintains its functionality.

The main focus of his talk was on progressive enhancement, which involves providing advanced functionality in environments where its supported. He also emphasized the importance of graceful degradation. Graceful degradation means that if your subscriber’s email client doesn’t support a certain functionality, you’ll still provide them with a pleasant experience.

there are bugs aplenty with ie's, the way to address them is by complimenting your otherwise sound html/css with fail safe code, rather than degenerating your sound html into hacky html for ie's sake.

And that just leaves the Word Outlooks (and their ever-aligning web based equivalents), and a few lesser used (for us) regional clients. Here, our div based layout reverts back to every story being on a new line. For #EmailWeekly, we’re ok with that.


Yet sales figures for certain neuro-psychotropic drugs are considerably higher than the incidence of the illnesses for which they are indicated would lead one to expect. This apparent paradox applies above all to neuropsychotropic drugs that have neuro-enhancement properties. The most likely explanation is that neuro-enhancers are currently undergoing millions of self-trials, including in universities – albeit probably not in their laboratories. The ten top-selling psychotropic substances in the USA include anti-depressants, neuroleptics (antipsychotics), stimulants and drugs for treating dementia.

Therefore client side validation should always be treated as a progressive enhancement to the user experience; all forms should be usable even if client side validation is not present.

There’s an important wrinkle when it comes to animating the menu away. When the user closes the menu, it will always disappear instantly, because the open attribute is, by default, removed immediately when the user clicks that summary element. In order to gracefully animate your menu out when it closes, we need some JavaScript. Here we can listen for clicks on the details element, and call preventDefault() on the click event, then use setTimeout() to determine exactly when that open attribute should be removed. This gives us time to trigger the closing animation with CSS. This click event listener will also fire when a keyboard user hits space or enter while the element is focused, which means no further listeners are needed for keyboard actions!

If you're creating an actual, informational web page, stick to frameless HTML, CSS and unobstrusive JavaScripts and keep in mind that the page should still be usable with scripting disabled.

JavaScript is more brittle than we care to admit. <a> elements function even if JavaScript breaks. Using anchors for your download means that a person can access what they need, even in suboptimal situations.

It is important to notice that if you are planning on making your application a PWA, you don’t have to rewrite all the logic.

The great thing about having our function in Promise form is that we don't actually need to "make it an async/await version" if we don't want to. When we call/execute the function, we can simply use the async/await keyword

We do know that, just like iMessage, this new approach will failover to SMS/MMS if a user cannot receive the encrypted variant or if bandwidth is insufficient on either end.

A couple of years after WhatsApp, Apple jumped into the game with iMessage—its obvious drawback, that senders and recipients had to be using iPhones, was overcome by integration with the standard SMS platform on those phones. If a recipient was not on iMessage or was offline, the message would revert to SMS.

Adopting TypeScript is not a binary choice, you can start by annotating existing JavaScript with JSDoc, then switch a few files to be checked by TypeScript and over time prepare your codebase to convert completely.

First proposed as a somewhat less unwieldy catchall phrase to describe the delicate art of "separating document structure and contents from semantics, presentation, and behavior"

In progressive enhancement (PE) the strategy is deliberately reversed: a basic markup document is created, geared towards the lowest common denominator of browser software functionality, and then the designer adds in functionality or enhancements to the presentation and behavior of the page, using modern technologies such as Cascading Style Sheets, Scalable Vector Graphics (SVG), or JavaScript.

Ritanserin, 5 mg, produced a substantially larger increase in SWS (51.4%) than either ketanserin, 20 mg (17.2%) or ketanserin, 40 mg (24.4%). Ritanserin has a significantly higher affinity than ketanserin for 5-HT2C receptor binding sites in the human brain and, based on estimates of per cent occupancy by the two compounds at brain 5-HT2A and 5-HT2C receptors, we conclude that SWS in humans is primarily regulated by 5-HT2C receptors.

Server-rendered markup can be progressively enhanced as element definitions are registered and upgraded by the browser.

Hardly a scientific survey, but the answers on Twitter and offline have been surprisingly consistent: server-side React for graceful degradation, jQuery and possibly shared templates (e.g. Mustache) for progressive enhancement
