What is Hackers' Pub?

Hackers' Pub is a place for software engineers to share their knowledge and experience with each other. It's also an ActivityPub-enabled social network, so you can follow your favorite hackers in the fediverse and get their latest posts in your feed.

We're doing our 25Q1 Hackday today at OEF. Everyone on our team -- designers, developers, operations, partnerships, product -- takes 24 hours to make something interesting and creative related to our mission. It can be code, a presentation, making something physical, creating a document. All self-guided, can be solo or collaborative.

Battle of the giants: Nvidia B200 takes the lead in FluidX3D CFD performance

just launched, and I'm one of the first people to benchmark 8x B200 via Shadeform, in a WhiteFiber server with 2x 6960P 72-core CPUs. 🖖😋

8x Nvidia B200 go head-to-head with 8x in the benchmark, winning overall (with FP16S storage) at 219300 MLUPs/s (~17TB/s combined VRAM bandwidth), but losing in FP32 & FP16C storage. 8x MI300X achieve 204924 MLUPs/s.

Prevost 成為首名來自美國的教宗,他取名「良十四世」,應該是示意自己當教宗後會受「良十三世」啟發

良十三世最著名的工作是教廷在他任內首度就勞工議題表態,認為教義要求教會關注勞工權益

因此,外界判斷,良十四世將關注勞工及其他社會公義議題,路線跟方濟各相若

不過,在同性戀、任命女性當主教等問題,良十四世以往公開的發言較方濟各保守、強硬

"Who Broke the Internet?" is a new podcast from CBC Understood that I host and co-wrote - it's a four-part series that explains how the enshitternet came about, and, more importantly, what we can do about it. Episode one is out this week:

It makes me super uncomfortable that globbing in Bash can turn into code execution. The fact that the name of a file can change the behavior of ls is scary. This also works for other commands that you tend to glob with, such as rm.

The 'ls' command showing files using the normal wide formatting. Once you add a file called '-l', then 'ls' starts showing files in the long listing format.

Something to be aware of if you work in a Microsoft shop with security requirements: Copilot on Sharepoint will apparently allow ACL bypass without logging or alerting.

You can just ask it for things.

It looks like what's going on under the hood here is that Copilot introduces a new category of user account for their agents, who have expansive read permissions by default and Copilot doesn't know how to map what the agent _can_ read against user permissions.

正在讀這本。現代人大概很難不在網路世界留下個人資訊,這些資訊該被如何看待,是能被再運用的財產,或者是一部分的人格?過往隨著個人死亡而逐漸淡化的記憶,如今像是無法自然分解的物質般漂浮於網海,一個亡者彷彿不曾離去的世界,如何改變活著的人的樣貌?
