@amadeus Nice!!!! Congrats!!

If you've been wondering what I've been up to, the team and I have been cooking up something new.

A new agent-native development environment deeply integrated with the GitHub graph. Not just for writing code, but all of the meta-work as well.

@pierrecomputer i hope those speakers made it to the video

[Lita 조원경 @litacho]

@sarahwooders Pieeeerre!!

@sqs @united Not a long flight, but flying out from SFO -> SEA on Sunday. User is lita

[Lita 조원경 @litacho]

@thorstenball @sqs Syncing all this state sounds hard. Excited to give Neo a try.

Also, when a customer states your product gave you another 9, no better endorsement.

This was Cursor btw, and how they use temporal for their cloud agents product.

[Lita 조원경 @litacho]

Achieving six 9s is an impressive feat. No wonder temporal has the reputation of being reliable.

SVP of engineering at @temporalio @psomal talking about how a blameless engineering culture leads to great results

No SLA violations even under cloud provider outages 🔥

If you have a project that needs fast, reliable, git based code storage that is built with modern, agentic workflows in mind then we should have a chat about code[dot]storage

@Golden_Bearz I approve of Tina fey being Berkeley. Timothy is piedmont, let’s be real here

[Lita 조원경 @litacho]

@isaacinthesky You are too kind Issac 😭 but you also had an impressive network stack stripe !! So your opinion has merit on its own!

[Lita 조원경 @litacho]

@rakyll The more abstraction and frameworks you add, you trade off some sort of performance as no abstraction/framework is going to be a perfect solution for your context unless you built it yourself.

[Lita 조원경 @litacho]

@rakyll Preach. Also because go builds so fast, I have fast feedback loops to test. But concurrency is going to be hard.

[Lita 조원경 @litacho]

@ahmetb Shutting down cleanly is tricky to get right and I always write it gross during the first pass.

I thought I provide a counterpoint of what Tauri provides, as we migrated our Electron app to Tauri. As with any technology, everything is just full of tradeoffs.

Since Tauri has a rust core, locks, threads, shared runtime memory, and os calls are much more performant than javascript/typescript. We heavily leverage concurreny, as we read and write to files on disk. Using a system language is going to be far more performant when manipliating a filesystem.

Tauri is also inherently secure out of the box. Tauri explicitly requires you to grant permissions for the filesystem, network, etc., and lets you scope resources. With Electron, you do have to open a port to communicate with the Node.js runtime, which might be a feature for some people. Tauri uses native bridges and function closures between the webview and Rust core, which is inherently safer than local-network IPC (you can encrypt data between the network calls, but you pay for that in performance) as the data never leaves the runtime. Also, using the OS webview, your app benefits when users update their OS, and the binary is smaller because you do not have to package Chromium separately.

But the real reason we migrated: native libraries. Using libgit2 via FFI and jj-lib natively is worth the tradeoff of WebKit bugs. We pass an OAuth2 token at runtime and run git push / git clone under the user's own credentials.

Yes, we do face painful WebKit bugs, especially around rendering the text cursor. But we thought that the cross-platform bugs were worth the trade-off of the security benefits.

I do believe that you can make an Electron app just as secure by using service workers and iframes. It is more work, and you do give up performance for it. But you can do it. If you want to go deeper, I gave a talk at Git Merge: https://t.co/LrgUJlLNM3 that covers our migration in more detail.

we've moved opencode desktop to electron.
it's faster, more reliable, and will replace our tauri build soon.
try it out in beta via the link below.

@fat I want one!! Next SF visit??
