Good catch. OP, exposing your application without authentication is a serious security risk! Quick anecdote: Last week, I ran a Redis container on a VPS with an exposed port and no password (rookie mistake). Within 24 hours, the logs revealed someone attempting to make my Redis instance a slave to theirs! The IP traced back to Tencent, the Chinese tech giant... Really weird. Fortunately, there was nothing valuable st…

I didn't know that, thank you.

> MCP is getting trendy, but a lot of people being drawn in can't find the actual meat of what it is outside of self-referential definitions. My comment was against the shallow dismissal. Do you think that the negative comments helped anyone locate the meat of what it is? Did they clarify or educate? Even the infamous Dropbox comment[1] was more constructive. I gently push back in the hope that we can have better dis…

Saying you "built an MCP server" is literally the same as saying you wrote a method though. Like you can write a single 20 line method to connect to a MySQL database, add the MCP tool decorator to the method and boom you "built an MCP server". But no one is posting up to HN saying "Look guys, I wrote a method which connects to a MySQL server", because it takes almost zero expertise and is not novel at all.

I didn't engage further because their comment made it transparent their protest is more about virtue signaling than anything of substance.

It will get you the correct answer, not a solution. Once again it’s a terrible example, I don’t know why you used it. It’s certainly not a gotcha

The reason I used it is that the correct answer to the actual problem is unknown and nobody has any idea how to solve it. No amount of sampling an LLM will give you a correct answer. It will give you the best known answer today, but it won't give you a correct answer. This is an example where LLMs all give correlated answers that do not solve the problem. If you want to scale back, many programming problems are going…

the correct answer is "the solution is unknown"

the correct answer is "the solution is unknown"

That's not what I asked the LLM for. I asked it for a counterexample, not whether a counterexample is currently known to humans.

Is that the correct answer to "write a lock-free MPMC queue"? That is a coding problem that literally every LLM gets wrong, but has several well-known solutions.

There's merit to "I don't know" as a solution, but a lot of the knowledge encoded in LLMs is correlated with other LLMs, so more sampling isn't going to get rid of all the "I don't knows."
