### AI overview

A tutorial on building accurate web countdowns despite background-tab timer throttling. It recommends calculating remaining time from an absolute deadline, forcing a render when a tab returns, and treating the server clock as the authority for consequential expirations.

### Source excerpt

Your checkout timer says 4:55 when the cart already expired. Why background tabs break setInterval countdowns, and the three-line fix.

### Source excerpt

Finding good content in the swamp of AI slop is hard, and whenever I find a blog post worth reading, I'd like to know when the author publishes the next one. For stupid reasons (like a day having only 24 hours, and me having a life), I can't periodically scan all websites I find interesting, but fortunately, I don't have to.

### AI overview

This commentary examines a large, generalized PHP code sample that builds hierarchical output from a presumed database source. It highlights probable SQL injection risk, unused array keys, dynamic localization fields, extensive number formatting and HTML string manipulation, string-based date-time parsing, and repeated code for child and sibling records.

### Source excerpt

Some time ago, Charles shared with us some awful PHP, aka the most common sort. Today's code sample is maybe a little too big to sum up, but I'll let Charles take a crack at it. It's so bad that even analyzing and laughing at it feels impossible. But it's so bad, I couldn't not share it. I'm the only one handling all the IT-related tasks at my company, and I don't have anyone here to vent or laugh about this kind of thing with. So, I figured, why not share it here? I'm hoping it'll provide at least a little bit of catharsis or some dark humor. To make sure the confidentiality of the codebase was respected, I took the liberty of generalizing it. You might notice some inconsistencies, but that's just me trying to keep things neutral while protecting the original structure and functionality. Apologies if it looks a bit patchy - the goal was to avoid revealing any specific details or sensitive code. The whole block is north of 400 lines, and it's doing a lot. Or well, maybe it's not, as you'll see. Let's star with the outermost layer. $resm_data = $data_source->fetchData("group=" . $item_id); foreach ($resm_data as $key => $value) { // rest of the code here } We fetch data from a data source, presumably a database, passing our condition as a string, which reeks of probable SQL injection, but I don't know what library they're using. I also note they're using the key/value style of array iteration, but never actually check the key. $option_id = $value->option_id; $resm_details = $detail_source->fetch($option_id); if ($resm_details) { $label = $resm_details->{"label$lang"}; $description = $resm_details->{"description$lang"}; $category = $resm_details->category; Nice little bit of "meta" programming to get their localization working, it'll fetch labelen or labelde as needed. Definitely not a horrible, dangerous way to solve that problem. We use that again to get our currency figured out. That lets us do number formatting. So much number formatting code. if ($category == 0)

### AI overview

The article presents an approach for keeping server-rendered HTML admin pages fresh without abandoning static HTML. It uses Molecule on the JVM to observe state, kotlinx.html to render HTML fragments, Ktor to stream updates over WebSockets, and client-side JavaScript with Idiomorph to patch the DOM. It also discusses using server-sent events for unidirectional updates and the scalability tradeoffs of long-lived connections.

### Source excerpt

Let's render a simple page with Ktor server and kotlinx.html: get("/users.html") { call.respondHtml { myLayout(title = "Users") { userList( users = db.users.value, ) } } } A reusable myLayout provides scaffolding, userList encapsulates the specific page content, and db.users is a StateFlow<List<User>> from the persistence layer. I've been doing this over and over to create admin dashboard pages for a project. It works great right up until you leave it open for a minute or two, and its content becomes stale. Client-side frameworks exist within the ecosystem to "solve" this, such as Compose for HTML or Compose UI for Web. If your house has a leaky pipe you can also "solve" that by moving to a new house. I simply will not bring myself to abandoning HTML let alone delivery of static HTML in the response. Efforts are underway to adapt Compose for HTML for so-called isomorphic rendering. This would involve performing the initial composition on the server to produce the static HTML for the HTTP response. Then, client side as JS, mounting the same rendering code to reproduce the DOM tree and incrementally update it for future state changes. Tomorrow's Compose today Instead of waiting, I brought my own Compose on the JVM from home in the form of Molecule. Instead of managing a UI tree over time, Molecule manages a single piece of state over time. We can use that to render an HTML fragment on the server as a string, and then stream that to the client. webSocket("/users.ws") { launchMolecule(Immediate) { val users by db.users.collectAsState() createHTML().userList( users = users, ) }.collect(::send) } That's it. Ktor gives us the webSocket, Molecule runs the StateFlow<String> which is piped into it, and kotlinx.html renders the HTML fragment of our existing content function. In the initial HTML payload you need to wire this up somehow. Something like: script { unsafe { +""" |const content = document.getElementById("content"); |const socket = new WebSocket("ws://" + location.ho
