I think we have quite a ways to go before that. The price is still pumped pretty high compared to what it would be without the Musk hype that got it to where it is. I bet we’d see a 30-40% drop in share price if they fired him now. They’re in a no-win situation

Maybe. Current prices certainly include probability that Tesla is able to pull off major transformation into more than just a car manufacturer (batteries, supercharge network, self-driving software, etc). The implicit assumption is that Musk is helpful for that - which would certainly have been true some years ago. Getting rid of him would be an admission that the loftiest dreams won't happen as fast as some would like, but doesn't necessarily mean they're out of the picture.

Had fun making this visualization of how security works - look right? https://eraser.io/git-diagrammer?diagramId=Gyr7VvuFOGNGsnznQ...

After seeing some really cool tools that build high-level overview diagrams of a repo, we wanted to see if we could create a tool for building any diagrams from a codebase (for the diagrams we support, which are architecture, ERD / schema, flow charts, and sequence diagrams).

Try it out on any public Github repo! A few notes: 1) Works best if you are pretty explicit with the prompt. We're only offering 2 free runs right now because of the expense involved. We have some examples built in and I've left a couple links below. 2) Works best on repos of a few hundred files or low thousands. More than that and it really helps if you can provide some explicit instructions on where to look. 3) The feature that links to specific code files is pretty fun.

Here a some examples:

Supabas real time updates: https://eraser.io/git-diagrammer?diagramId=2XXiOvPfJjtfMbWdM... Subase realtime architecture: https://eraser.io/git-diagrammer?diagramId=nIvgs2dMvarCYJ8zV... Primsa migrations: https://www.eraser.io/git-diagrammer?diagramId=uK7UptrWd4EEY...

I was also unclear what this actually did. Not sure how much this helped, but it is a nice visualization of what's happening: https://eraser.io/git-diagrammer?diagramId=ysiiD14zhpPemvoJO...

I was curious about Mistral so I made a few visualizations.

yoelhacks commented on When did estimates turn into deadlines? domainanalysis.io/p/archi... · Posted by u/alexzeitler

I often see takes on this topic from the engineering side. "It's hard!". "Managers just don't understand".

It feels like as a community, it would be useful to get more articles seeing things from the other side and exploring functional approaches beyond provide-a-worst-case-scenario-estimate.

There's a reason this dynamic is so pervasive. In order for everyone in an organization to do their job well, people do often need a realistic set of estimates. Can sales promise the prospect this integration? Can marketing plan a launch for the new feature? Can the CPO make a reasonable bet on a new line of work?

In my experience, the nuance here is more about handling the mis-estimates. How do we discuss the risks up front? How much work should we put into contingency planning? How do we handle the weeks / months before a deadline when it is clear that we need to limit scope?

The difference lately is the number of tools that are now in place for WebAssembly development and the new extensions to WebAssembly (WasmGC, Memory64, etc.).

Despite 28 years of effort at optimization, JavaScript is outperformed by WebAssembly. There's not much coming back from that:

Javascript is outperformed by WebAssembly in the sense that it runs faster.

A lot of things that bring a lot of value to a lot of people are still much, much faster to build via the JS / TS ecosystem.

It absolutely makes sense that calculation-heavy workloads will be ported to WASM, but there's a lot more to building an app.

I used to work on an app that very heavily leaned on Elasticsearch to do advanced text querying for similarities between a 1-2 sentence input and a corpus of paragraph+ length documents.

It was fascinating how much tokenization strategies could affect a particular subset of queries. A really great example is a "W-4" or "W4" Standard tokenization might split on the "-" or split on letter / number boundaries. That input now becomes completely unidentifiable in the index, when it otherwise would have been a very rich factor in matching HR / salary / tax related content.

Different domain, but this doesn't shock me at all.
