@AlexFinn Same result with Claude Code; I feel both models are good enough to build

Excited to share that @lmnrai has raised $3M to build open-source observability for long-running AI agents.

Laminar is how companies like @browser_use, @OpenHandsDev, and Rye see what their agents are doing, understand why they fail, and spot patterns across millions of runs.

@creem_io why don’t you send notifications before charging a subscription? I think it’s not cool in 2026

3/ I use Opus 4.5 with thinking for everything. It's the best coding model I've ever used, and even though it's bigger & slower than Sonnet, since you have to steer it less and it's better at tool use, it is almost always faster than using a smaller model in the end.

If your an Elixir engineer, you can't afford to sleep on AI. It's quite possible that Elixir may become *the* language for AI in the next few years. It's kind of crazy how much good stuff there is out there right now.

@dhh, as a cloud-exit expert looking for an alternative to Apple Photos — why don't you try having NAS at home and Synology or a similar ecosystem for your own independent private digital space. Backups, encryption, and all of these are easier than they seem.

@lexfridman @JeffBezos It’s not gonna be a fun one because you can’t smile 😊😊😊

Just realized that almost every my success started like that —

@stats_feed Similarly, the higher cost of fuel in European cities is often compensated by much smaller distances (and less traffic) you have to drive compared to North American cities like Toronto.

[Alexander Lukianchuk @landpro]

@stats_feed From the cost-living perspective, it would be better to assess average trip cost because in different cities different distances involved — an average taxi trip in Zurich or Basel will be somewhat around 4-5km while Houston or Dubai will be double or triple of that.

@alex_avoigt That is reflected in their car interiors overwhelmed with features. BMW and Audi are slightly better but not faraway too — they tend to duplicate a function with multiple ways of doing it rather than simplify and limit to the best ways (opinionated approach)

Imagine you own 1% of Apple.

What this means, in its most basic sense, is that by putting up 1% of the capital, you own 1% of all of their current and future profits. That is a fair exchange and it’s well understood.

But if instead, after your money was invested, their goals changed and you didn’t own 1% of their maximum profits any more but rather 1% of some lesser profit (or, even worse, no profit at all) along with a 1% share of Apple’s efforts on student debt reform or the Russia-Ukraine war, you may be confused and think this wasn’t what you signed up for.

Replace Apple with Target, and student debt reform/Russia-Ukraine with Gay Pride Month and the customer and shareholder reaction from Target is below.

Target’s billions of revenue loss and market cap losses add to the tens of billions of dollars already lost by Disney and Bud because of a similar market and customer reaction.

Why is this happening? Do customers and shareholders not care about social issues?

The message being delivered by customers and shareholders to public companies seems to be that they do not want companies to take social positions. They want companies to exist to maximize value for customers and maximize profits for shareholders.

So who is pushing for companies to take positions on politics and social issues if not customers and shareholders? Employees?

A non obvious conclusion that these customers and shareholders may see and companies and employees may not yet is that other organizational models exist (foundations, non-profits, B-corps) to take more effective stands on political and social issues than a C-corp.

And if a company can maximize their enterprise value, it can also enrich employees who can then funnel more of their money than they could otherwise into these causes as they saw fit.

A separate implication of this is that customers and shareholders seem to not want companies to be Swiss Army knives and do everything. They want specialists who are very good at one thing.

Boards and CEOs are probably formulating their all company emails now…

@maxkarpis I have my sources as well. And I am sure that I am not revealing something I shouldn’t 😅

@TeslaSynopsis @Tesla Once FSD is super smooth (not just safe), we will roll out a free month trial for all cars in North America.

Then extend to rest of world after we ensure it works well on local roads and regulators approve it in that country.
