I assume/hope that Tesla teleoperators are required to have drivers licenses in the states in which the cars they are operating are located?

New comment by jnsie in "A Primer on Bézier Curves – So What Makes a Bézier Curve?"

jnsie — Thu, 30 Apr 2026 12:31:06 +0000

I haven't thought about Bézier Curves since my undergrad a long time ago. I distinctly remember wondering at the time why so many lecturers added extra hurdles (i.e. the need to understand the intricacies of Bézier Curves) in their assignments rather than letting students focus on the computer science/programming concepts they were meant to be learning.

That part is indeed interesting. I would have thought this would be exactly the audience likely to travel with the device, use it as a large monitor for daily work, etc. Apparently not.

That price always made it seem like a tech demo. I suspect that they would have sold like crazy at (the unfeasible price point of) $500.

> It would be incredibly useful if before you were about to edit a file, the version control system would warn you that someone else has made changes to it already or are actively working on it. In large teams, this sort of automation would reduce conflicts, as long as humans agree to not touch the same file. This would also reduce the amount of quality regressions that result from bad conflict resolutions.

Bringing me back to my VSS days (and I'd much rather you didn't)

Ah, this old fallacy. There are myriad examples of the rich striving to be richer and the powerful fighting to gain even more power. Why would it be any different with Musk? If anything I suspect (this is absolutely an unverifiable opinion; I am not stating it as fact) that Musk's driving force is to become the first trillionaire.

I think it's important for those responding about their Duolingo experience to include the tier that they are using. Specifically, I wonder if the conversations with AI, and the "explain this" feature in Duolingo Max change outcomes? I'm new to Duolingo, chose the max tier, and feel that I'm learning quite a bit specifically because I am having simple conversations in French daily (albeit with an AI that seems to me to have questionable hearing at times). I haven't used it long enough to provide insight or even judge the platform, but for those using the more expensive tier(s) I wonder your thoughts...

How reliable are UV indexes? Genuine question. The iOS weather app is far from 100% reliable and I wonder the margin of error regarding the UV index number it provides.

Why the disingenuous response. What I linked was an article entitled "New Report Exposes Live Nation-Ticketmaster’s Monopoly Control of Top Arenas and Amphitheaters Worldwide". The fact that they monopolize venues strongly discounts your suggestion that they will "slowly die or be replaced quickly by something better like an AI ticketing system".

I highly doubt it. The merger with LiveNation made them much more than a ticketing service. They now also handle artist management, concert promotion, and venue ownership. In fact "Live Nation-Ticketmaster maintains "monopoly control" over the top 100 amphitheaters and 100 arenas worldwide" [1]

You missed out. The stained glass windows are absolutely stunning. I normally don't get too excited about stained glass, but they are truly beautiful as is much of the interior.

> Honestly, within the US I can only think of NYC as having a better payment system as they were first movers on tap-to-pay adoption and it's basically fully adopted.

Chicago is pretty good too. IIRC they also have tap-to-pay. In fact, I think they had it before NYC

It's not about the merit of the argument but rather the act of shutting down any argument by declaring something as a fact. It's completely unnecessary and quite off-putting.

I love Balsamiq and it was great to see it mentioned here. While the wireframes are intentionally simple looking, the ease of creating a mockup is unsurpassed IMHO.

That reminds me - we're staying in an Airbnb later this summer and I've been meaning to research gadgets to detect hidden cameras. Now I guess I need to look out for microphones too. We're going in quite the dystopian direction.

That's wear and tear and not down to negligence on the driver's part. It's abhorrent that a rental company would attempt to charge a customer to fix something like this.

A decentralized Uber is an interesting thought experiment. I imagine the processing power required is a big barrier to entry for the FOSS community.
