Coffee linked to slower biological ageing among those with severe mental illness – up to a limit | King's College London

New research from King’s College London finds that coffee consumption within the NHS recommended limit is linked to longer telomere lengths – a marker of biological ageing – among people with bipolar disorder and schizophrenia. The effect is comparable to roughly five years younger biological age.

[中國戰機兩度雷達照射日本F-15　日方深夜緊急抗議⸺中央社](cna.com.tw/news/aopl/202512070)

"日本防衛省今天表示，從在日本近海航行的中國航空母艦「遼寧號」上起飛的戰鬥機，昨天下午兩度對日本自衛隊戰機進行雷達照射。防衛大臣小泉進次郎今天凌晨召開記者會指出，「這是極其遺憾的行為，已向中方強烈抗議，並嚴正要求防止再次發生」。

中國軍方使用雷達照射自衛隊的事件，曾於2013年1月發生。當時中國海軍艦艇在東海公海上，以射擊時使用的射控雷達，照射了海上自衛隊的護衛艦。

雷達照射指的是戰機的雷達被啟動並鎖定目標，意味著已經完成發射前的準備，極具挑釁意味。"

//中國這條戲路還在加碼。

@cancel I'm thinking of changing how mollytime's audio output works such that patches define one or more sound emitters each with a relative position to the observer so that patches can be decoupled from the speaker configuration. What the final outputs mean make more sense with headphones to me since they're just your ears, but I'm not sure what they correspond to with freestanding speakers.

Do you have any wisdom to share for implementing DIY positional audio mixing?

Wave of vandalism in South Korea

About a week ago, vandals began defacing the map in South Korea. Over the course of that week, I rolled back hundreds of changes, and with the help of the sites moderators, I banned over 50 malicious accounts.

The CEO of The Onion set the publication's goal for 2026 to have more subscribers than The Washington Post. At the rate the latter is going, that won't take long.

"For reasons we don't like or understand, our work has become increasingly important."

"Look, we're an independent company, we don't use AI to write headlines and make art, and we're one of roughly three publications who are up for the fight. Unlike other places, The Onion is quadrupling down on being a pain in the ass, politically. Are you?

It's been a big year for us at The Onion, but as media collapse accelerates, it is unfortunately going to be a fucking great year for us next year. So I sent an email to our members with our goal for 2026: More print subscribers than The Washington Post. This is, tragically and hilariously, feasible. Here's a note I sent to our members with how we spent our money last year, and how they can expect us to abuse it next year. We spent a lot of money taunting ICE and Jeffrey Epstein, we spent even more money yelling at Congress for not taunting ICE and Jeffrey Epstein, and we stupidly continue to try to buy InfoWars. In short: The Onion is an independent company, we don’t use AI to write headlines or make art, and we’re one of roughly three publications who are up for the fight. Unlike other places, The Onion is quadrupling down on being a pain in the ass, politically. Quadruple down with us. The world might make a tiny bit of sense. | 76 comments on LinkedIn

Capitalism is *all about*, at its core, building decentralized systems which on inspection turn out to be centrally controlled, or controlled via a "one dollar one vote" democracy of the five or six richest people in the system (in other words informal centralization, without the committee that makes the decisions having a name).

The decentralized internet systems that capitalism builds reflect this. There's lots of examples of it. Bitcoin, Ethereum, Bluesky.

@mcc a thing i need to keep communicating to folks is, in almost all cases, centralisation is cheap, decentralisation is expensive.

here's how I like to think about it:

decentralisation is great, better, more humane, more resilient, easier for more people to benefit from, etc, etc but it comes at the cost of significant redundancy, integration, and communication overhead. if you don't have an external source of revenue/resource to cover this cost, to either:

- artificially lower the buy-in and upkeep of the system, and/or
- effectively force it to stay decentralised while also warding off lower cost monolithic competitors,

it's going to amalgamate through sheer thermodynamics. and if there is only one source of ‘free energy' then that just means the system is already effectively centralised, whether or not that's even the intention of the source.

You’re absolutely right — you are Pagliacci. It would certainly be difficult for you to attend your own performance! I should not have given such paradoxical advice, and I apologize deeply for the error. There is no excuse for my failure.

Nevertheless, comedy is a powerful healing force. My recommendation is to seek out live entertainment. For example, great clown Pagliacci is in town tonight. Go and see him. That should pick you up. 🔗 Sponsored Reply (Great Clown Productions, Ltd.)

성시경을 좋아하지 않지만, 사람들이 잘 모르는(?) 것 중 하나는
성시경은 201x년대 후반부터 일본활동을 위해 꾸준히 준비하고 있었고
17~19년도부터 밑바닥에서 시작한다는 생각으로 일본에서 데뷔 앨범, 싱글 준비, 소극장 공연등을 조금씩 진행하며 방송에도 얼굴을 비추던 상태였습니다.
그리고 한일 무역 갈등 => COVID 로 이어지면서 활동을 이어가지 못하다가 이번에 다시 이어가게 된 것.

Zebra-Llama: Towards Efficient Hybrid Models

Zebra-Llama: Towards Extremely Efficient Hybrid Models

With the growing demand for deploying large language models (LLMs) across diverse applications, improving their inference efficiency is crucial for sustainable and democratized access. However, retraining LLMs to meet new user-specific requirements is prohibitively expensive and environmentally unsustainable. In this work, we propose a practical and scalable alternative: composing efficient hybrid language models from existing pre-trained models. Our approach, Zebra-Llama, introduces a family of 1B, 3B, and 8B hybrid models by combining State Space Models (SSMs) and Multi-head Latent Attention (MLA) layers, using a refined initialization and post-training pipeline to efficiently transfer knowledge from pre-trained Transformers. Zebra-Llama achieves Transformer-level accuracy with near-SSM efficiency using only 7-11B training tokens (compared to trillions of tokens required for pre-training) and an 8B teacher. Moreover, Zebra-Llama dramatically reduces KV cache size -down to 3.9%, 2%, and 2.73% of the original for the 1B, 3B, and 8B variants, respectively-while preserving 100%, 100%, and >97% of average zero-shot performance on LM Harness tasks. Compared to models like MambaInLLaMA, X-EcoMLA, Minitron, and Llamba, Zebra-Llama consistently delivers competitive or superior accuracy while using significantly fewer tokens, smaller teachers, and vastly reduced KV cache memory. Notably, Zebra-Llama-8B surpasses Minitron-8B in few-shot accuracy by 7% while using 8x fewer training tokens, over 12x smaller KV cache, and a smaller teacher (8B vs. 15B). It also achieves 2.6x-3.8x higher throughput (tokens/s) than MambaInLlama up to a 32k context length. We will release code and model checkpoints upon acceptance.

Embarrassing admission

I did not realize until today ostriches aren't native to Australia. As a clueless USian all I knew was Australia has ostriches and Australia once had something called the "emu war". This name makes it sound like emus were an invasive species. No. Ostriches are native to Africa, Rheas to South America, Emus to Australia. Ostriches in AUS are an invasive species introduced by colonizers. The "emu war" was because the colonizers didn't like the native emus eating their crops

将棋という趣味について語る - さんちゃのblog

これは 専門外の趣味を語る Advent Calendar 2025 の七日目の記事です。 今年から始めた趣味である「将棋」について書こうと思います。 お仕事ではスマートフォンゲームのサーバーを開発したり運用したりといったようなことをやっており、将棋も「ゲーム」ではあるので、そういう意味でつながりが全くゼロというわけではないのですが、専門外の趣味と言ってよいでしょう。 将棋との遭遇 将棋のルール(駒の動かし方)自体は小学生ぐらいのときに覚えていました。 動き方が駒に書いてある将棋盤が家にあったんですよね。 shop.kumonshuppan.com ただ、当時は将棋で対戦してくれる相手が五歳年…
