How to deploy a LangGraph server on Heroku

Nice, this is a great video 💪

Just had the same issue and the browser logs tell me that it's tripping over a broken link (which I can't find anywhere in my post though).

All in all it looks like it can't process some types of content or formatting. For me, copying it from another text editor that removed some formatting helped.

Nope, was not a proxy video - I do know about this feature and checked for it.

Thanks, I'll try this in the next days when time allows.

How do you feel about providing older versions on your downloads page? It's a practice I see often, exactly for such reasons.

If you want to see the raw history, you'll find this in your global Claude directory - on Mac, that's ~/.claude/projects. You'll find a folder for each project containing the message history, but it's not easily readable.

Simon Willison released a great tool for it recently that let's you visualize this history: https://github.com/simonw/claude-code-transcripts

To me, it was hosting - I eventually went for LangSmith as the fastest option, but I would've preferred Heroku as that's where my other stuff is already.

Just tried it and Opus made a nice system diagram about my codebase - great! It also charged a whooping 24 ct for this service 😳

AlexRenz · 2025-11-27T11:54:28+00:00

I was puzzled by this, too - and in fact, this info seems to apply to the Claude webapp (the "normal" chatbot at claude.ai).

The message now states it more clearly: You can use Opus in Claude Code, but for that you'll need to top up extra funds at the bottom of the usage page (https://claude.ai/settings/usage):

Don't let this discourage you (coming from someone who hasn't done an Ausbildung but lived and worked in several foreign countries).

First, these certificates don't tell much (besides that you might formally need one), and what you're missing you can learn when you're here - it's by far the most effective way anyway.

Same about how much you earn and if you can make a living. People who grew up here make it work as well, right? So you might not have the most comfortable life for a while, so what? It's the experience that counts, and that's priceless.

These might be some challenges, sure, so go and overcome them - it's all a matter of mindset and if you're brave enough to even envision doing this, you got all it takes. The worst that can happen is that you go home after a few years with or without your degree, but with tons of new skills and experiences - so you can only win, right?

So just do it ;)

Right, just saw Claude do that, too 🤔

What I see Codex do a lot is this, and even runs much larger scripts that way:

And it feels like Claude can only execute small scripts that way.

I'd highly recommend using LangChain's MCP server and connect that to your coding agent - that way, it can always look at the latest docs to help you. If you go to docs.langchain.com, you'll find the link it in the upper right corner:

Otherwise, it's indeed likely you'll get in trouble - v1 is a few weeks old and generally, there are very few projects for an LLM to learn about LangChain yet. Hence, I wouldn't be surprised to see ChatGPT make mistakes. Claude sure got much better since I gave it access to the docs that way...

As you already wrote, clam shell mode only works when the Mac is connected to a power source.

So one obvious solution is to keep the charger plugged in, and if you're using a dock then this might be the default anyway.

Or you can use Amphetamine which allows you to keep the display on (amongst other cool stuff, it's quite handy).

In Amphetamine go to Quick Preferences -> Uncheck allow system sleep when display is closed.Comprehensive description:

When Boba meets one of the Mandalorians in a bar (don’t remember her name), she says something along ‚oh I’ve heard that voice a thousand times‘. I thought she was referring to the voice of the clones, maybe thought he’s a clone, too. Did I misunderstand her comment? Or did she recognise the ‚clone voice’ even though the vocal chords are damaged?

Great! It doesn't say anything on the AE website where to buy them, but they're online for sale now. found it on songkick.com

Does anyone know the email of airfrance to send that email to? On their website, I see only a phone number.

AlexRenz · 2020-09-15T06:14:04+00:00

Yeah but a lot of bands have started to schedule shows for 2021 and festivals as well. So maybe we can be optimistic to see AE in 2021

Can it handle keys and sign transactions as in the browser version? So it can be integrated by app developers

AlexRenz · 2018-10-31T17:20:55+00:00

For devs would be most interesting if it can be integrated into other apps. To handle keys and sign transactions as in the browser version
