I work in renewable energy, and I build mobile apps for consumers joining the renewable energy revolution. We need to do more to address climate change, today!

I'm here to talk about renewable energy, apps, EVs, LGBTQ+ identity, leadership, games, realtime rendering, AI & Tech politics and policy, curating content, and...whatever else seems interesting.

man, I dont even use Figma for personal & side projects because its so expensive. I still occasionally fire up sketch or freehand it.

Figma is a work tool only and I'm disappointed by its MCP tooling which feels late and behind where it should be, I just feel forced to use Figma Make which stays in their walled garden without practical utility and connections to my actual codebases

There are two factors I see with this:

I sometimes like having my content editorialized. Some of the LLM writing tropes are ok to me—I'd delete them if I added this prompt to my instructions (but I wouldn't). But my editorial preferences—the sense of voice and tone I want the LLM to make—are rarely these tropes. Instead, I have a positive prompt of the angles I do enjoy.

However, what is cloying about these tropes for many is that they're becoming empty words. Instead of tack-sharp summaries or reductions to simple understanding, the model is spilling extra tokens for minimal value—I don't need to read "it's not X, it's Y" for the n-th time today. I'd really prefer tighter, more succinct reading that actually directly quotes sources (which modern models rarely do to avoid copyright traps).

You can usually save more by generating solar locally and using it to power the home and charge the battery, then discharging the battery during peak hours (usually around and just after sunset) to earn the most. Obviously higher upfront capex.

Pure grid cycling is also frowned on by some utilities.

Not all homes are made equal: different appliances & electronics from different vintages, etc.

I have 2 EVs (Tesla and BMW), an electric oven, and a homelab rack (but no HVAC), and my usage was 34.4 MWh last year — with 100% from Solar and Powerwall.

Notably, about one-third of users stopped taking the medication during the study period.

This isn't always the patient's choice—my insurance/PBM (CVS Caremark) dropped coverage for the GLP-1 that I was taking (Zepbound) and had several rounds of prior-authorization shenanigans over a few months before they approved the previous-generation GLP-1, Wegovy. Now I've had to start the ramp-up of a different medication again, which hurt and stalled progress. Evil.

I think this is an example of above average but not great AI writing. I still read it to the end because the subject is interesting and there is enough focus (and, seemingly) expertise on the topic.

I think the telltale for me that makes me count as heavily AI-assisted is the lack of inclusion of real, inline examples of actual fares & their restrictions. I know I've seen them broken down before in other content. But not once here was there a full readout of an actual fare bucket & its rules. I think a human writer would have been tempted to include even one of those as an artifact, but an AI as a topic reviewer/summarizer/collator won't unless explicitly instructed.

A new PNG spec 1 year ago

It seems like this new PNG spec just cements what exists already, great! The best codecs are the ones that work on everything. PNG and JPEG work everywhere, reliably.

Try opening a HEIC or AV1 or something on a machine that doesn't natively support it down to the OS-level, and you're in for a bad time. This stuff needs to work everywhere—in every app, in the OS shell for quick-looking at files, in APIs, on Linux, etc. If a codec does not function at that level, it is not functional for wider use and should not be a default for any platform.

I think the point of BlastDoor, as covered in the post, is that Apple is indeed working to prevent injection at the cost of silently failing & poorly handling legitimate messages.

By being pedantic about the formatting, BlastDoor is protecting the recipient from an exploit that would abuse that type of issue.

So, not impossible, but less likely than you think

These counterfactual comparisons are a slippery slope and not as helpful as you think. I hardly think that you, I, or most others have an intuitive understanding for what happens when a 1 gram meteor hits earth. Have you ever witnessed that?

The average failure state of a battery is not similar to detonating a handful of TNT on an airplane, which is a more instantaneous explosion. Sure, some battery failure states are violent and would unquestionably be a cause for an airplane to call a mayday and land, but something like puncturing a soft-cell battery is still a slower release than TNT.

We should just expect people to get better at understanding useful units — I'd prefer someone learns Wh since it is indeed a useful metric—kWh is the usual major unit of energy at home, and Wh is just smaller than that.

I would like to see more DF on HN. The something rotten in Cupertino was a shattering post—people in my circle who do not read DF were discussing and sending it around, and I work at a place where so many dang people read HN. So I agree with Gruber’s concern.

I’m surprised this post too is already flagged.

Do signs point toward Apple adopting a unique, new cell chemistry for what will be their high-volume budget product for the next few years? It would have probably been a marketing line if so, similar to the C1 modem. A bigger battery doesn't imply new tech.

(Yes, the phone expensive now, but these SE-tier phones typically get discounts pretty quickly after release through carriers/non-apple retail; and then a bigger & formal sale price decrease when the next phone generation comes out.)

Apple Invites 1 year ago

Less latency is a feature, not a bug. We've just grown too used to latency in everything we use.

Apple Invites 1 year ago

This era of new experimental apps from Apple (Invites, Journal, Sports) has me excited about the future of app design. Vibrant colors, bold personality-driven typography, etc. The SwiftUI style onboarding screen that features the carousel is really fun. This approach feels very Apple'y, but gives me more freedom to explore designs for my own app to have its own unique voice on iOS, while still feeling in-family with Apple's other more experimental UI.

There are a few misses.

- I already declined a friend's invite, but that doesn't get auto filtered away, so my "decline" is still the primary thing the app has to show me. It's still my only invite, so maybe it gets filtered to the back of the card stack if there are multiple?

- I also don't seem to be able to see friends I know who were invited to the party (but have not yet responded). Perhaps it was because it was shared as an invite URL in a group chat rather than manually inviting everyone?

Mistral Small 3 1 year ago

This is really exciting—the 12-32b size range has my favorite model size on my home computer, and the mistrals have been historically great and embraced for various fine-tuning.

At 24b, I think this has a good chance of fitting on my more memory constrained work computer.

It's also just harder to support because of the sheer fragmentation.

I give my engineers different Android phones as their primary development devices and yet the weird Android issues that keep cropping up are near constant.

As an adult with too much disposable income and a 3090, it just becomes a local LLM server w/ agents when I'm not playing games on it. Didn't even see the potential for it back then, but now I'm convinced that the xx90 series offers me value outside of just gaming uses.
