Mini stocks were traditionally used as way to invest in asset as a security. But currently with all the ETFs that are backed with physical asset itself, I'd choose that way.

Holding asset yourself (gold) causes logistical issues and massive buy/sell split on your side, but it has some advantages too.

Assets traditionally used for such hedge are already massively inflated (look gold an silver price charts), so I'm not sure it's worth it.

This all depends on what timelines you work on, how many assets you are trying to protect.

Alternatively you protect yourself by lowering your dependence on steady income.

They did the same with free version of Google Workspace. It's just no longer free.

Nango is cool, but pricing is quite high at scale.

My daily job by now is massively using AI to develop AI agent designer, which means a lot of stuff like this.

I really did not even want this, it just happened.

I suggest you add https://github.com/tensorchord/pgvecto.rs for vector search as well

New comment by czechdeveloper in "Why we no longer use LangChain for building our AI agents"

czechdeveloper — Fri, 21 Jun 2024 06:17:02 +0000

I used langchain in one project and I do regret choosing it over just writing everything over direct API. I feel their pain.

It had advantage of having standardized API, so I could switch local LLM to OpenAI and just compare results in a heartbeat, but when I wanted anything out of ordinary (ie. get logprobs), there was just no way.

Vehicle by definition can't be connected to the house constantly. I can imagine this lowers need for house battery size, but not need for it's existence. House power consumption is very random.

This sounds so random. Did Russia ever proved they can do AI in any significant capacity?

By now, making UI with (by now not completely) SPA frameworks specifically made for that task is just better developer experience. I won't go back to pretty much html string concation via templates. Why do people keep pretending it's better in any way is lost on me.

As a gun enthusiast, that sounds really impractical. Amount of compromises involved must have made it bad in all use cases.

I made universal CLI project where adding new function as is simple as adding new class with arguments parsed into an object.

It has 49 actions now even when I keep removing obsolete ones.

I also made PDF viewer for comparison of 2 documents - synchronized zoom and scroll, even overlay.

With small classes and dependency injection as fist class citizen, default constructors make sense for developer ergonomics.
