Good morning Fedi friends!

Please join me in giving a warm welcome to my interns Riyen (@patel.riyenThe Life of Tarzan) & Sam (@samaabergSamuel Aaberg). They will be working with me through the end of June on videos promoting the Fediverse. This is their .

Sam & Riyen are two talented film students who are : a mere 7 days ago they had no idea what the Fediverse was. I have the immense honor of introducing them to it.

We are filming this week! Send us good vibes 🎥✨

Three people sit on a couch. On the left: a young man with black hair and a beard wearing a black blazer and white pants; in the middle: a woman with long brown hair (me) wearing a blue and white striped t-shirt and blue jeans, holding a clapper with the text: "Fediverse Promo no.1 by Elena Riyen & Sam - May 2nd 2025"; on the right there is a young man with glasses and light brown hair wearing a red hooded sweatshirt. A bookshelf and various items are visible in the background.

Hab gestern noch ne Talkshow geguckt, da hat ein Gast erzählt, dass sie Zahlen in Farben sieht und da ist es mir wie Schuppen von den Augen gefallen. 🙃Ich auch!! 🤓Aber es war mir gar nicht bewusst. Aber alle Ziffern von 0-9 haben bei mir ne bestimmte Farbe und so bestehen dann alle Zahlen aus diesen Farben. Und ich kann schon immer gut mit Zahlen. Lasse aber auch gerne mal Zahlen. 🤣

不斷的練習跟自己對話；不斷的重組自己與這個世界重新連結，卻還是沒有進展。

沒進展也沒關係，可是卻發現自己好像跟這個世界脫節，那種靈魂跟肉體錯開的感覺，一直以為只是過度抽離，直到跟友人聊起近況，他說我可能有輕微解離狀況。

那種對現實不真實感很微妙，感覺自己好像不存在，卻像遊魂。

Matrix-vector multiplication implemented in off-the-shelf DRAM for Low-Bit LLMs

MVDRAM: Enabling GeMV Execution in Unmodified DRAM for Low-Bit LLM Acceleration

General matrix-vector multiplication (GeMV) remains a critical latency bottleneck in large language model (LLM) inference, even with quantized low-bit models. Processing-Using-DRAM (PUD), an analog in-DRAM computing technique, has the potential to repurpose on-device DRAM as a GeMV engine, offering additional high-throughput processing capabilities to widespread consumer devices without DRAM modifications. However, applying PUD to GeMV operations in the LLM inference pipeline incurs significant overheads $\textit{before}$ and $\textit{after}$ in-DRAM computation, diminishing the benefits of its high-throughput processing capabilities. This paper presents MVDRAM, the first practical system to accelerate GeMV operations for low-bit LLM inference using unmodified DRAM. By leveraging the data sharing patterns and mathematical linearity in GeMV operations, MVDRAM orchestrates the processor and DRAM to eliminate the costs associated with pre-arranging inputs and bit-transposition of outputs required in conventional PUD approaches. Our experimental evaluation with four DDR4 DRAM modules shows that MVDRAM achieves comparable or even better inference speed than the processor-based implementation for GeMV operations in low-bit (under 4-bit) LLM. In particular, MVDRAM achieves up to 7.29$\times$ speedup and 30.5$\times$ energy efficiency for low-bit GeMV operations. For end-to-end LLM inference, MVDRAM achieves 2.18$\times$ and 1.31$\times$ throughput improvements, along with 3.04$\times$ and 2.35$\times$ energy efficiency, for 2-bit and 4-bit quantized low-bit models, respectively. MVDRAM has the potential to redefine the AI hardware landscape by demonstrating the feasibility of standard DRAM as an LLM accelerator.

아이스 아메리카노 제로카페인을 주문해서 마셔보았어요.

헤이즐넛향이, 과장하게 말하면 가향커피와 비슷한 수준으로 강하게 들어왔고
점도는 약간 콜드브루 커피와 비슷한 느낌이였어요.

커피열매가 아닌 것들을 사용해서, 커피가 가지고 있는 복합적인 향을 담으려고 시도한것은 느껴졌으나 어색한 느낌과 특히 뒷맛이 너무 텁텁해서... 개인적으로는 불호인 부분이 있었어요.

이런 텁텁한 부분 때문에 우유와 섞은 음료를 추천하는걸지도 모르겠구나 싶야요

US politics, Trump

Trump unsure if he has to follow the constitution
The president of the United States caused new controversy by answering "I don't know" when asked if he has to uphold the constitution in his position.

Trump usikker på om han må følge grunnloven. USAs president skapte ny kontrovers da han svarte "jeg vet ikke" på spørsmål om han må overholde grunnloven i sitt embete. Isak Løve Pilskog Loe I dag kl. 04:01

서울대저널 - 성노동자·퀴어 혐오에 맞서, 《너의연애》 출연자와 함께하는 연대 성명 발표

▲《너의연애》 공식 포스터 ⓒ디스플레이컴퍼니 웨이브(Wavve)에서 방영 중인 레즈비언 연애 예능 프로그램 《너의연애》 출연자 김리원 씨와 연대하는 성명이 발표됐다. 5월 2일 오후 3시 30분까지 5,064개 개인·단체가 연명했다. 연대 성명을 제안한 연혜원 씨는 ‘《너의 연애》에 출연 중인 리원이 과거 이력으로 사이버 불링과 혐오에 노출된 것에 깊이 분노하며, 문제의식을 공유하기 위해 연대 성명을 요청하게 됐...
