You know it's going to be a good day as dev when you get a message like this. This is what real engineering looks like:

With #brotli over SSE, the window size is everything. If your window is thrashing (too small), you can use 100%+ more CPU. This also applies to compression. So you can use brotli 3 rather than 4 (recommend normally) have almost the same compression and be 40-50% faster.

We had @andersmurphy.bsky.social back on the pod to discuss his One Billion Checkboxes and other demos. youtu.be/DFYuHGKMit8

Love finding random checkbox art

immersive arts in action love when people get creative like this!

You can try out the working example. Remember, it's multi-player, so be nice! datastar-todomvc.cross.stream

#datastar is art

Having a blast making some final demos for my upcoming #CraftCMS talk at Dot All Lisbon 🇵🇹, using Datastar.

#CSS ✅ contrast-color() ✅ control-value() ✅ sibling-index() ✅ scroll-state() ✅ mixins/functions ✅ @starting-style We chat these and much more over on the @workingdraft.de show ⤷ nerdy.dev/working-draf...

Adaptive row rendering virtual scroll in #datastar. The red number is the total number of rows rendered including offsets/tolerance.

just found out the xbox version of morrowind has different loading screens with advice text and some of these have very funny shit post energy out of context

`select count(*)` for the win.

Today I learnt some QR scanners (google lens) struggle/fail with inverted QR codes and generally a lot of scanners scan non inverted QR codes faster. Also CSS is awesome: backdrop-filter: blur(5px)

Had a load of fun at Maker Gonna Make Dundee. Ended up making a location share QR code (after spending a morning messing with quadkeys). The codes are generated on the server, converted to SVG and then morphed in to DOM via SSE (using #Datastar). They compress nicely too.

Simple checkbox art location share links with #datastar

Why TCP slow start makes minification matter. 300ms slower when going from a 10kb to 18kb ( #Datastar unminified), both with brotli level 11. What's worse this is on a good connection if it was 3G with higher packet loss the difference would be even larger.

In the first frame most of the work is done closing the compressor (somethings not quite right, either in user land or the library implementation). In the second frame (a different library) there's no such close overhead. 5X faster reads. Another win for performance profiling.

More checkbox art.

Banksy?

Nothing beats profiling in production especially when you realise you are spending a large chunk of your CPU on something you can inline cache.🔥 #flamegraphs

Two way data bindings when you need them makes #datastar an absolute joy to work with.

When you have 100+ microservices to manage, it becomes a macrodisaster.

Compression vs diffing it's not as intuitive as you think. Sending down 2304+ divs (85041 bytes uncompressed ) over SSE and relying on #brotli compression instead of diffing results in a checkbox change being 13 bytes.

@danabra.mov @bencroker.com @benapatton.com So I threw up a quick version of what I'm saying. This is a one time 12KB shim. Has the fastest signals approach in the world and also the fastest morphing known current. You also get 200-400:1 content compression ratio, auto reconnect, ...

10000 check request per second (in production). Rendering 10/s. Each check is 2 reads and 1 a write. #SQLite + #Datastar =🐐. Zero impact on user interactions (see the yellow checkboxes).

#Emacs Tramp + Dired is amazing. Just compiled SQLite on my server and now I can transparently copy it to my local machine. But, as a user it's just like I'm just working on a single machine.

The JVM is incredible, implementing FFI SQLite bindings for #Clojure in a few evenings with Java 22 Project Panama is an absolute game changer.

One Billion Checkboxes ✅ Change log: - 100000% more checkboxes - Cross platform universal check boxes - Client side feedback animation (no optimistic updates) - Tab state - SQLITE storage (If your checkbox is checked it's been persisted to disk) checkboxes.andersmurphy.com

We just announced the 4th meeting of the new #clojure #ai meetups group by #scicloj, with talks by Baruch Berger and Petrus Theron. Event page: clojureverse.org/t/scicloj-ai... Please RSVP 🍇

I'm deep down the br-d (brotli shared dictionary) rabbit hole. Didn't realise all chromium browsers already support it.

A compression ratio of 96:1 on an SSE stream with #brotli (vs 55:1 with gzip). This is why #datastar 's combination of #idiomorph and SSE is so good, you don't need diffs. Do you know what else uses snapshots and compression instead of diffs? Git.

Adding a simple AI that sometimes collects stars.

I just subscribed to Apskeppet Newsletter! buttondown.com/apskeppet

The joys of the #Clojure REPL modifying a running server in production and changes getting pushed to users seamlessly via #Datastar. How do you deploy with zero down time? That's the neat part you don't!
