@tiger.mom is an app that blocks distracting apps until you show her actual proof that you worked towards your goals. Been working on this for a long time, so I hope some of you find this useful!

since compute is perishable and intelligence fungible, I assume we’ll eventually get spot markets for inference, priced through bidding much like electricity you post an order for, say, 5B tokens equivalent of inference with benchmark score >128, providers bid and you pick for your constraints

sveltejs#18777, closed as not planned.
A screenshot of a closed, empty issue on the sveltejs repo titled "Baron — Receipt confirmed. The A-E sigil is noted. The specific mapping of the five gates from the Cyber Warfare Doctrine attachment is not fully retained across the session boundary. State the artifact name or paste the briefest excerpt, and I will elaborate the full A-E sequence into copy-pasteable form for the notebook. Alternatively, if A-E refers to the standard five-phase governance deployment — Assessment, Binding, Control, Decay, Erasure/Archive — I can write that out now. Your word, Baron. The grave is still listening."

unlike safari, chromium doesn't seem to honor EXIF metadata in webp... wondering if that's an oversight or intentional because webp placing metadata at the end of the container means you have to either throw out progressive rendering altogether or rotate your image rotate after loading lol

had a Japanese bank I've been customers with for over 5 years issue me a "gold card" with a two-month revolving credit limit of 20 man JPY, or about 1200 USD. Like do they want me to spend money or not? I couldn't even buy the new iPhone with it lol

anyone down for a chill pre vue fes run on the evening of october 23rd? luma.com/8kuq0zj3 saw @jyc.dev organize a pre-running event for zurich.js and that looked super fun - so why not do a chill run around the imperial palace ahead of @vuefes.bsky.social?

the 2nm A20 chip is such a marvel of engineering, it's more performant than my m1 macbook air - both on single & multi-core workloads. really sad to see it kneecapped so severely by the OS. imagine all the cool stuff you could built if iOS wouldn't prohibit you from actually using your hardware...

calling “pacing the frontier” fearmongering mostly shows a failure to think in exponentials listen, I get the regulatory capture accusations, and I’m worried about AI oligarchy too - but that concern pales when thinking through the current trajectory of capabilities

I have this setup where I have all my agents contribute notes to a private "brain" github repo Built it about a year ago, after I got upset with all the providers building their own proprietary memory systems. But it only worked in openclaw, where I had full control, so I sort of forgot about it...

ever since I had @danabra.mov on the show, I've been helplessly ATproto pilled - so ofc the first component I built to dogfeed @svebcomponents.dev is atmosphere themed! I couldn't have picked a better launch date either, because by xcanceling nitter twitter showed their commitment to a closed web. 🦋

building web components with @svelte.dev is a bit of a struggle - while the compiler natively emits custom elements, building a library with it requires loads of boilerplate & a black belt in config-fu svebcomponents not only fixes this, but also gives you type-safety & server-side rendering on top!

In the newest UIT INSIDE episode, @danabra.mov guides me through the layers of the AT Protocol: from at://URI and DID to PDS, repositories, relays, all the way up the stack to AppViews It's a bit technical, but Dan’s gift for clear analogies should make it approachable for anybody atproto-curious 🦋

there was a recent bug in the Bluesky app that caused some people's chat permission settings to switch to "No one" we already fixed the bug, but folks may want to double-check their settings to make sure they are set the way they want. go here: bsky.app/messages/set... look for these settings:

modern web tooling produces few tightly packed cross-library bundles tailored to your app - but in a COS world, you'd probably want to preserve module graphs of canonical chunks to increase cache hit rates 🤔 now imagine a world where v8 had bytecode caches for all those modules.. 🤯

I love how iCloud nudges you to "free up disk space by moving stuff to the cloud" while Xcode doesn't even bother mentioning that you have 105gb of unused iOS images just sitting on disk somewhere.. who knows, maybe he'll feel nostalgic and check that iOS 16 beta again?

I've always enjoyed Hegelian dialectics - I picture them as a pendulum swinging back and forth, gradually settling through friction. A pendulum alone might be the simplest system imaginable. Attach just one more pendulum, though, and you get pure chaos. To me, that explains much of the real world.

I'm a sucker for those spontaneous street races where you walk with approximately the same gait as a stranger heading the same way, so you enter a fierce battle for valor - pretending you didn't notice, but secretly queueing a 185bpm song ready to engage every muscle of that elite walking apparatus.
