Looks pretty promising, would be great to see some more documentation around pushing data out to elastic, etc.

Small nit, the GitHub link at the bottom of the page leads to docusaurus' GitHub, not the project. It took me more than one attempt to realise the project's gh was in the sidebar.


Documentation is indeed very early, the main focus now was to pitch the idea correctly and help people understand what it does. I will then work on integrating multiple sources (Debezium, WAL-Listener...) and multiple destinations (Elastic, Redis...).

Good catch for the footer, thx!


With indent.com sunsetting in 2 months time (July 15th 2024), does anyone have any suggestions for access control systems?


Was this something like tailscale, teleport, or ngrok?


It sets up temporary authorization. "Type /access in Slack or from the web app. Give a reason and how long you need access, that's it!"


Do take a look at Adaptive [1]. It is combination of what teleport and indent does.

PS. I am one of the co-founders.

Curious to hear what issues you faced (please!). I use FF (on Linux) as my main daily driver and I haven't had any issues with Causal (disclaimer, I work for Causal).

(granted, the experience is optimised for Chromium based browsers, but FF is not forgotten).


i registered before ok. now i can only see the alert on top to use chrome. no other content.


We've had a number of very interesting technical challenges along the way to this 2.0 release:

- traffic tiering and balancing based on request's perceived amount of work

- low latency data loading during our calc loop

- implementing a selector framework to unify all the stores used by the application

- redesigning the formula editor to make human friendly yet expressive enough for the most hardcore user (fun UX challenge)

We really ought to start blogging more about these things :D.


>redesigning the formula editor to make human friendly yet expressive enough for the most hardcore user (fun UX challenge)

I work in this space. I don't envy this. Been through it more than once.

Did you also have challenges with circular references?


We've had "fun" solving this for Phosphor which has similar parts to Causal, but is focused more on real assets and emphasizes connection with computable contracts.

For circularity, we found that we could keep the UX dynamic by making a deep copy of the circular part of the DAG behind the scenes, asking the user to determine which variable in that path should be "resolved", hard coding that variable in the copy, then solving that variable to zero through a newton optimization. Once optimized (in parallel to main graph), it feeds back into the main DAG just like any other dependency.

Would be a silly approach in Excel, but not so much here.


please do! spin up an engineering blog on hashnode. https://danluu.com/corp-eng-blogs/


We have released a few bits actually! https://causal.app/blog/scaling is one of my favourites (HN discussion: https://news.ycombinator.com/item?id=32000400)


Machines like arrays, sequential access, avoiding conditions, and not touching memory unless you need to (compression == performance).

Looks like you've traveled the enlightenment path to array languages! The first time I read Whitney's K language description was a singular mind-expanding moment.


More of this please.

Same in the UK.


George Carlin had some great quotes indeed (this specific one comes from his take on the environment [1]).

Interesting, cause living in the South East I mostly find drivers that are quite polite on the roads (giving way, respecting crossings, stopping traffic to allow you to merge into the main road, etc).

I suppose it's a matter of expectations. Originally from Portugal so I'm used to seeing far worse people driving on the road.


Exactly the same problem in Portugal.

People tend to stick to the outside lane as they feel that if they go on the inside lanes they won't have the opportunity to move to the outer lane when they are near their intended exit due to other cars being on the outer lane.

IMO this stems from lack of education (driving lessons are not adequate) and the fact that everyone's looking after themselves (i.e not respect for other road users (which also explains the ludicrous speeds on the roads, road rage, queues, etc))


I hate roundabouts, at least partly for this reason. Whenever I'm taking anything other than the first exit, I'm moving round just praying that no-one's going to join or drive up alongside me...

(And don't get me started on driving lessons. Here, in the UK, they're an absolute joke!)
