Fast KV Compaction via Attention Matching

Scaling language models to long contexts is often bottlenecked by the size of the key-value (KV) cache. In deployed settings, long contexts are typically managed through compaction in token space via summarization. However, summarization can be highly lossy, substantially harming downstream performance. Recent work on Cartridges has shown that it is possible to train highly compact KV caches in latent space that closely match full-context performance, but at the cost of slow and expensive end-to-end optimization. This work describes an approach for fast context compaction in latent space through Attention Matching, which constructs compact keys and values to reproduce attention outputs and preserve attention mass at a per-KV-head level. We show that this formulation naturally decomposes into simple subproblems, some of which admit efficient closed-form solutions. Within this framework, we develop a family of methods that significantly push the Pareto frontier of compaction time versus quality, achieving up to 50x compaction in seconds on some datasets with little quality loss.

If you're on LinkedIn and are thinking about verifying your account with them, maybe read this first. It walks through LinkedIn's privacy disclosure to identify 17 companies that may receive and process the data you submit, including name, passport photo, selfie, facial geometry, NFC data chip, national ID #, DoB, email, phone number, address, IP address, device type, MAC address, language, geolocation etc. Unsurprisingly, it seems the biggest recipients are US-based AI companies.

Once men tur­ned their thin­king over to ma­chi­nes in the hope that this would set them free. But that only per­mit­ted other men with ma­chi­nes to ens­lave them.

Ouch, this is really not a good look for Ghost, @johnonolanJohn O'Nolan

“Ghost (CMS) took some heat from the community for a longstanding SQL vulnerability not being addressed in the project's Docker image”

forum.ghost.org/t/self-hosters

Edit: They owned up to it, and have a plan in place to fix: forum.ghost.org/t/self-hosters

Self-hosters left vulnerable to XSS vuln due to second-class Docker support

Ghost has again publicized a vulnerability in their software without a published Docker image without a published Docker image which contains the fix. Ghost has published 6.19.1 with a SQL injection fix, but the most recent Docker Official Image is at 6.18.2. After this happened last time, I started collaborating with @ngeorger on a more secure alternate image and there’s now one that he created and I’ve successfully tested with 6.19.0. Perhaps he can push a 6.19.1 release soon. Keep an ey...

Also, ich muss Microslop irgendwie ja auch danken. Im JuZ steht noch die Migration weg von W10 aus. Dadurch, dass W11 inzwischen ganz offensichtlich nutzerfeindlich, Datenschutz-verletztend und unsicher ist, dampft sich die Diskussion sehr angenehm auf W10 IOT LTSC als Notnagel, oder endlich der Schritt Richtung Linux ein. Und ich werde letzteres ganz, ganz dringend anraten. Mal schauen ob wir das hinbekommen, auch wenn Linux für ein paar Mitarbeiter wenige Jahre vor Rente knackig wird.

I was today years old when I learned that The Squirrel Nut Zippers performed a special version of Put A Lid On It on Sesame Street.

Brass solos are excellent!

Sesame Street: “Put a Lid On It” (HQ) (2000)

I usually don’t upload clips from the 2000s, but this clip definitely needed a quality upgrade and the song’s pretty neat. You can check out the Squirrel Nut...

Vivaldi Snapshot的自動隱藏功能，啟用之後UI會變成Arc/Zen那樣只有網頁畫面，讓人又想用了，而且需要的時候macOS版的UI彈出來有配合Liquid Glass

不過我要吐槽Snapshot版，macOS輸入法候選字的UI會白底白字...

P.S. 原來是我的Vivaldi選了暗色UI的緣故

POLL: Fedi people, do you have a website or blog or personal wiki or some other kind of online Thing That You Control Yourself that other people can find you on that isn't paid for / maintained by someone else, meaning YOUR THING is at a web address like you.whatever, not at you.someonelse.whatever or someoneelse.whatever/you, I mean are you paying the tenner a year or however much for a whole-ass domain name all for yourself (or for you and a small group of IRL friends), and if not do you want to be, THE POLL, and here is the guidance and elaboration on options:

1) No and I don't want my own site, Fedi and/or other social media scratches that itch for me just fine and I'm content with this arrangement

2) No, but I have a Vague Yearning or a Curious Itch and I wonder sometimes what it would be like, but so far it's just feelings and not plans, I haven't taken any concrete steps towards making My Own Website a real thing that exists, but I'm comfortable saying that I would probably *like* it to exist some day when I'm ready

3) No, but more of a Not Yet than a no; maybe I've bought a domain name and not put anything on it yet, or I haven't yet bought a domain name but I'm researching my options (whether I do it in a lazy few minutes here and there or in focused making-notes sort of study, both count for the purposes of this question), I've spent some time thinking about this With Intent, and I feel less "*wouldn't* this be nice" and more "*won't* this be nice" about this endeavour

4) Yes I own at least one domain name, come on Dan this is Fedi, and at least one of my domains even have websites or services associated with them

BOOST THIS TOOT to get an INCREDIBLY INACCURATE IMPRESSION of how many people have and/or want websites and a more accurate picture of how many people On Fedi have and/or want websites

On this day 8 years ago I had an early version of wezterm in a decent enough shape that I was considering using it as a daily driver for real work. I don't recall how well that stuck in that first week!

I can tell from the washed out color in the screenshot that it was before I had learned to whisper the words of power that enabled SRGB.

I can't believe it's been 8 years already.

A screenshot from a facebook post that I made on Feb 20 2018 that depicts wezterm running on Linux, running vim inside, with the source code for wezterm open in vim. Alongside the image is a post made by myself describing how I switched from my own hand written software compositing logic to using egli to do it via EGL, and how I planned to use the resulting implementation for real work the following week.
