This is why compilers for e.g. c++ should just halt after the first error, instead of spewing pages of template failures because of a typo elsewhere

98% of the time those lengthy messages are useless, but the other 2% of the time they're critical to tracking down the problem.

A year or two ago Visual Studio added a pop-up that parses such lengthy compiler messages into a clickable tree list. I found it annoying at first, until I discovered I could dock it to the side, ignore it 98% of the time, but still go look at the details when relevant. This is an idea other compilers should copy.

Maybe ships should copy this approach too: issue fewer warnings, but provide a list of warning details for review when necessary.

> Then you look around and see "startup X gets to $1M ARR a month after launch" and shit like that and I'm feeling terrible about how we're barely growing.

Comparison is the thief of joy. I fall into this trap almost weekly. Success stories are incredibly rare and we only see the splash, not the iceberg of failure just beneath the surface.

I think about my current business constantly even though on paper we are making enough to keep this thing going forever but it never feels enough.

I felt this post and appreciate the honesty.

And similarly:

  slow growth is terrible

Slow growth is awesome! Slow growth gives you time to address the challenges of growth, and think through sensible solutions.

Rapid growth feels like you're constantly plugging holes in the dike or putting out fires.

Like you I've had brief moments of jealously seeing a company that started after mine and grew faster. But when I think rationally, I just wish them well, and realize I'm happy with any pace of growth that's not negative.

Better idea: write code. Don't waste your teams' time with back-to-back hour-long meetings.

Qt is terrible. Since a couple of years they want a login just to download the code required for a build and I really have zero desire to get a bunch of marketeers that are wondering if I'm ripe for the plucking yet just because I've decided to fix some bugs in open source code.

StellarScience · 2 months ago

  git clone --branch v6.10.1 https://code.qt.io/qt/qt5.git .

No login required.

They do require a login to download precompiled binaries, but what self-respecting Hacker News reader wants those?!

Ok, I'll admit, I've done it. And yes, I received Qt marketing at that email alias for a while, but they've stopped.

And remember, Qt has an LPGL license too, not just Commercial and GPL.

EDIT: Ah, ranger_danger pointed out that https://download.qt.io/archive/qt/6.10/ hosts binaries with no login required as well!

StellarScience · 2 months ago

Ignoring the git commit message strawman (those can include "what/why the change", not "what/why the code") and the Uncle Bob strawman, the final code block looks fine. But notice:

  // translate will replace all instances; only need to run it once

This is a "why".

  // Replace all symbols

This is a "what". It's better conveyed by improving the function name rather than by a comment:

  String replaceAllSymbols() {

Ultimately this article buttresses conventional wisdom about comments.

Love you Bryan, but:

> Companies that have disdain for their own customers will be reviled in return. Such companies may be able to thrive in the short term, but they do not endure in the limit.

Oracle has endured nearly 50 years. Sun did not endure.

I don't want to live in a world where one of the most successful and widespread corporate strategies is also disturbingly un-humanistic, but we're never going to find a better way unless our mental models for how customer relationships map to business success actually align with reality.

> Companies that have disdain for their own customers ... do not endure in the limit.

This is a very common sort of wishful thinking that lets people bypass hard decisions. You create a company that loves its customers and employees and vice versa because you want to run a company that way. There are plenty of examples showing it's possible to run a sustainable business that way, and also plenty of counter-examples. There's no guarantee that it leads to business success or maximizes profits, it's just a choice you make.

The problem with AI is privacy.

Firefox should be the browser that respects you privacy (the only one...). Integrating AI undermining the efforts of making it the privacy oriented browser.

For now the AI is forced and ridiculously complicated to disable (with new options in about:config poping in each new version). The promise to have an "disable all IA features" is still a promise.

StellarScience · 3 months ago

Years ago our company consolidated on Firefox because we could rely on it to not send our information to remote servers. At that time other browsers made it hard to disable telemetry. Firefox was then the only browser that could forward Kerberos tickets to remote servers, for highly secure two-factor authentication and single-sign on.

I'm personnally sad that now we have to consider banning Firefox for company use, because it's hard to verify that we've disabled every AI "feature" that might funnel our data to remote servers.
