有趣的實驗

高效能顯示卡並不需要高效能電腦
https://www.jeffgeerling.com/blog/2025/big-gpus-dont-need-big-pcs
這篇文章探討了將高階顯示卡接到 Raspberry Pi 5 上作為 eGPU 的可行性,並將其效能與傳統桌上型 PC 進行比較。作者最初質疑 Pi 的單 PCIe Gen 3 x1 通道是否足以支撐現代 GPU,但透過一系列測試發現,在特定工作負載下,Pi 的表現竟然相當接近 PC,且在能源效率上甚至更優。

在實際測試中,Pi 在媒體轉碼(Jellyfin)、GPU 渲染(GravityMark)及 AI/LLM 推理等多個場景下表現出色。儘管在大檔案媒體轉碼上,Pi 因 PCIe 帶寬受限而落後,但對一般家庭或輕量轉碼用途已足夠。GPU 3D 渲染幾乎完全依賴顯卡,Pi 在效率上甚至勝過 PC。AI 模型測試中,Pi 與 PC 在中小型 LLM 推理表現接近,部分模型表現甚至超過 PC,而效率則常優於 PC。

文章也提到多 GPU 配置的實驗。透過 Dolphin PCIe 交換板,Pi 可以連接多張顯卡,並利用 PCIe 直通技術減少瓶頸,使大型模型(如 Llama 3 70B 或 Qwen3 30B)能運行於 Pi 上,與高階伺服器相比僅差 2% 左右。雖然多 GPU 設定在效能上不一定超過單張大卡,但在可擴展性上提供了可行方案。

總結來說,傳統桌機在原始效能與易用性上仍占優勢,但對於特定使用族群,如以 GPU 為主、對電力消耗敏感的使用者,Raspberry Pi 5 配合 eGPU 是一個具成本效益且高效率的替代方案。這次實驗主要是為了探索 Pi 的極限及 PCIe 技術的應用,並非實際建議取代桌機。

"where were all the trans people before?"

We hid. And if we didn't hide, we died.
- we were deemed clinically insane.
- we we imprisoned.
- we were put in institutions.
- we were forcibly medically castrated.
- we were tortured with electric shocks.
- we were lobotomized.
- we were hunted down and killed.
- our murderers claimed "panic" and were set free.
- many of us chose the "easy way out" instead.

Helping trans people exist is good, actually.

요즘
경력단절여성 -> 경력보유여성 이랑
쉬었음 청년 -> 잠시 숨을 고르고 있는 청년 이랑
여성가족부 -> 성평등가족부 처럼
쓸데 없이 용어를 왜 자꾸 바꾸려고 하는거지
하는일이랑 상황은 바뀐게 하나도 없는데 ㅋㅋ

私は H-II ロケット8号機を指令破壊した当時、NASDA 広報室に詰めていたので……関係者の皆さん、今は壮絶な時間を過ごされてると思いますけど、とりあえず何か食べれるものが手近にあれば食べれるとき食ってくださいね……腹が減っては戦はできぬ、ですよ

그렇다기보단 그냥 그 변태들이 "한국 블루스카이 주류"를 선점한것 이상도 이하도 아니긴 해요 non-sexual 계정들은 이를 선점했다 하기에는 영향력, 수가 너무 미미했으며 섹계들은 트위터에서 정지먹은 사람들 중 일부만 와도 순식간에 non-sexual 계정들 머릿수를 그야말로 압도해버리고 비율적으로 절대적 대다수를 차지해버렸어요 반대로 말하면 한국 블루스카이의 섹계 점령 현상은 트위터가 그동안 얼마나 심하게 성매매, 성범죄 밭으로 작용했는지를 보여주고 있다고 생각합니다.

MAGA Boomer: At your age in 1970 I paid off college & bought a house with hard work.

Millennials: In 1970 college was 5% of median salary. Now it’s 44%. A median home was $24K. Now it’s $417K. The top marginal tax rate was 70%. Now it’s 37%. Sure maybe you did work hard—but then you closed the door behind you.

I'm on another Amazon A/B test from hell. This time when I search for something it brings up their stupid AI assistant and no matter how many times I close it, it'll come back up on the next search. I hate it so much.
