davideg··on Volvo delivers 74-tonne electric truck
> The truck runs 12 hours a day, with a stop for charging when the driver takes a break

I'm curious how much range it gets before needing a charge, and how long it takes to charge during that break. Running 12 hours a day doesn't tell us anything about distance covered.

davideg··on Desalination system could produce freshwater that is cheaper than tap water
> In the meantime, the leftover salt continues to circulate through and out of the device, rather than accumulating and clogging the system.

I don't want to detract from the innovation of this, however my understanding is that one of the largest unsolved problems with desalination is what to do with the waste product: usually incredibly salty brackish water. Dumping it back into the ocean can be disruptive to the local ecosystem.

A quick search turned up this Scientific American article about the issue: https://www.scientificamerican.com/article/slaking-the-world...

"The excess salt decreases dissolved oxygen in the water, suffocating animals on the seafloor"

"In addition to harming sea life, extreme salinity also makes desalinating the water more difficult and expensive."

davideg··on Ask vs. Guess Culture
I appreciate you calling this out! In my community we started talking about it as "Ask" vs "Attune" culture. On the one hand do you assume everyone will be explicit with their wants, needs, and boundaries? On the other, do you pay attention to who you're engaging with, their general disposition, their communication style preferences, etc?

I personally like to keep a balance between the two extremes and try to adapt my behavior to who I'm engaging with (you can tell I'm comfortable in an "Attune" culture environment, but I appreciate when people are up front and communicative about their needs, wants, and boundaries). Considering the power differentials at play and the ability for someone to enforce their true boundaries is really important to me, and also having meta conversations to encourage folks to speak up about their needs and boundaries.

In a work context, I will have a meta conversation with someone about their preferred communication style, how they want to receive feedback, how they want to be checked in with, etc. to avoid mismatched communication expectations.

davideg··on The rule says, “No vehicles in the park”
What was your percentage of agreeing with the majority? Greater than 50%?

I think your response to this exercise actually proves the author's point. I see people disagreeing with your take in the comments or making (to their perspective) reasonable arguments in favor of their choices.

Whether you found it personally "crystal-clear" to answer the way you did says more about your personal confidence and way of understanding rules than about the task itself being unambiguous.

davideg··on ChatGPT Plugins
> The only think that scares me a little bit is that we are letting these LLMs write and execute code on our machines.

Composable pre-defined components, and keeping a human in the loop, seems like the safer way to go here. Have a company like Expedia offer the ability for an AI system to pull the trigger on booking a trip, but only do so by executing plugin code released/tested by Expedia, and only after getting human confirmation about the data it's going to feed into that plugin.

If there was a standard interface for these plugins and the permissions model was such that the AI could only pass data in such a way that a human gets to verify it, this seems relatively safe and still very useful.

If the only way for the AI to send data to the plugin executable is via the exact data being displayed to the user, it should prevent a malicious AI from presenting confirmation to do the right thing and then passing the wrong data (for whatever nefarious reasons) on the backend.

davideg··on Show HN: Generate styled web pages with just Python
As someone who knows Python and always has to google CSS properties and javascript functions, this is a really sweet little project! I'm not going to reach for this if I need to have a website that needs to look a very specific way, but for cranking something out to display some data or documentation, this seems really nice.
davideg··on Google urges Android phone users to switch off Wi-Fi calling
I greatly appreciate your nuance to cut through the FUD! I reflexively disabled Wi-Fi Calling on my Google Pixel 7 Pro phone.

A cursory Google search indicates that exynos modems don't support CDMA (apparently it's too expensive to license from Qualcomm) and are largely sold outside the USA. As a Verizon customer in the US, I believe this means I'm in the clear.

Like another commenter, a side effect of responding to this article was discovering that the March 2023 security patch is available (even though I didn't get a notification about it).

davideg··on Twenty-five years of curl

In November, in the middle of Covid, I finally got a US visa.[1]

davideg··on Clothing designed to confuse facial recognition software
In the description of the technology in the Collection section they explain that facial recognition systems mistake the patterns on the clothes for animals like dogs, giraffes, and zebras.

I don't know how this technology works. Is it not possible to train a system to say "human face" or not without accidental identifications of non-humans?

Edit: (And thus not be fooled by this?)

davideg··on Are you ok?
Mornings that I spend outside experiencing my five senses and staying in my body leave me feeling refreshed, grounded, and energized[1]. From this place I tend to have more attention and patience. I seem to have better access to empathy.

Mornings that I spend from the minute I open my eyes glued to my phone screen leave me feeling basically the opposite. My attention is completely fractured. My general sense that I'm okay is harder to access and instead I often feel baseline anxiety and uneasiness. I feel less patient and more judgemental.

I can't claim that this causes me to be more caustic online (and offline) with people that I disagree with, but I certainly can see why that might be true. Especially when I'm bombarding my mind with divisive, provocative news headlines that are designed to get a rise out of me.

davideg··on 5-MeO-DMT, a Review by a Confused Customer
This is profoundly intense.

For all those experience seekers taking psychedelics (or really any substance/drug), it's worth remembering "The Iron Law of Exactly Enough":

"O seekers, I am here to remind you of a truism of drug experiences, which I call the Iron Law of Exactly Enough. It goes as follows. If you have a wonderful experience with a substance—whether it’s caffeine, a martini, or a pill in Ibiza—and it’s absolutely perfect, but you want just a little more of that perfect experience, don’t. Don’t do more, don’t chase it. Be very happy that your trip to the Substance Lottery has gone this way."
