I was part of the early alpha for this, they opened a beta wait list today. The thing that is different here is that they remove 99.9% of the friction to create agents, the target user group is not a user who can run Claude Code and install

What is the lifetime of the Ray workers, or, in other words, what is the scalability / scale-to-zero story that makes this serverless?

(disclaimer: I work at Microsoft, but am not directly involved with Durable Functions) Being a library is a pretty interesting feature! Correct, Durable Functions allows you to write task-parallel orchestrations of task-parallel 'activ

Peter, how does this compare to Azure Durable Functions? (Say, for the sake of argument, that you are comparing the Python version of both) Are there things that fundamentally you can do in one and not in the other?

I may be missing something, but in addition to this threat of prompt injection, you also have to trade trusting the arbitrary MCP server for trusting MCP Defender. In the default mode, the app will interpose on the communication between, sa

I was using Pocket to save articles to listen to in the car, with their ok TTS feature. Does anyone know of an easy solution that allows me to click to save an article, and then have it automatically on an app on my phone so I can listen wh

This was an interesting quote from the blog post: "There is one silly technique I discovered to allow a LLM to improve my writing without having it do my writing: feed it the text of my mostly-complete blog post, and ask the LLM to pre

It would make it a bit harder to detect that you are using a VPN, but it shouldn't be hard for the ISP to detect that all your traffic is being sent encrypted to a particular IP address. They wouldn't be able to see you are using

A long time ago (2011) when I was teaching the networking course at Brown, the final assignment in the course was to create the equivalent of iodine, IP-over-DNS tunneling [1]. Being a course assignment, the handout only outlines the soluti

This paper [1] models some simple (r) NN as ODEs, and uses ODE tools to train and for inference. It’s a start. [1] https://arxiv.org/abs/1806.07366

Really great research work from Kay Ousterhout. Sparrow extends the "power of two choices" [1] to a more general formulation, and makes it really cheap to find very good choices (i.e., low-load servers) to run a task, without havi

Also, don't call from the same phone you received the call on, if on a landline . One time (I can't find the reference) scammers called from the bank, suggested the person called back to the number on their credit card. The perso

Could not agree more. I think one big problem with Bolsonaro's discourse about the election system -- he was absolutely correct that the current system is not fully verifiable -- is that it became too politicized, and that he or his su

This is great indeed, and makes it for 2 illustrations from Van Jacobson's papers, separated by 28 years! (The 1988 paper and the 2016 BBR paper)

In Networking, two illustrations of congestion control are just fantastic IMO. First one is [1], by Chiu and Jain (page 7, figure 5), showing that Additive Increase / Multiplicative decrease is the only simple policy that converges amo

Here's one way (YMMV) of reading academic papers. It usually takes time, and a couple of passes, and you may try to understand the ideas and impact first, to then move to the design/implementation, and the experiments that demonst

This is pretty cool. Have you considered not killing the instance after the user disconnects, but pausing the container instead? This opens up the whole tradeoff space between how long you keep the state vs cost to the infrastructure/p
