brk··on 3.4M Solar Panels
I'm not aware of janky laws in Florida, when I had panels installed on my last house in 2017 there wasn't much friction from the perspective of laws. Standard permitting process (basically just expensive paperwork).

The issue was with the insurance companies. We had an 11.6Kw array, and it was getting difficult to find insurers that would allow more than 6Kw of rooftop solar.

brk··on Another Day Has Come
Yes, I'm aware how inflation works, you missed my point. Many technology things have effectively gotten cheaper over time, when you account for overall performance/specs/capabilities/etc. The "we don't know how to make a $500 computer that doesn't suck" statement of today would be more like "we don't know how to make a $350 computer that doesn't suck".
brk··on Another Day Has Come
There is more to it than just accounting for inflation. Apple has done a number of other things in the meantime, including designing and manufacturing their own chips, that have changed the economies of this. Until the very recent RAM price explosion, a sub $500 computer in 2008 was probably more like a sub $350 computer today.
brk··on All phones sold in the EU to have replaceable batteries from 2027
In a perfect world, sure. But people also want phones these days that are physically durable, have some degree of waterproofing/water resistance, maximum battery life, etc. Many of the demands and expectations of a modern phone aren't easily compatible with a replaceable battery design that can withstand the incompetence of the average end user.

Most common advice is that you have to be at least one of the sides somehow. Reddit famously did this with lots of sock puppet accounts to foster discussions and create pseudo activity.

In your case, I'd probably start by reaching out to businesses in mid-size metro markets, ones where bike couriers don't already exist, and offer to save them on shipping small packages. Build up a list of clientele and encourage them to contact you for jobs when they need to ship small ad-hoc stuff. That should give you an idea of demand. Then start posting on craigslist and facebook looking for delivery drivers, then start match-making. From there encourage the drivers you find to sign up on your platform for future work.

brk··on An AI robot in my home
From the blog post, it appears that the eyes and head have some amount of actuation. So it meets the robot criteria, even if just barely.
brk··on Hobby CNC machining and resin casting (2015)
Start with one of the cheap kits on Amazon. A good chunk of the learning curve is software/design/workflows. On the machine side, learning how to properly secure your work pieces, and find the right bits, speeds, and feeds is another art. You can do all of that on a ~$300 3018 CNC kit. Your work output is limited in size, and precision, but that doesn't matter as much when you're just trying to get the hang of things.
brk··on Ask HN: How do you handle clients who don't pay on time?
I require payment upfront before work starts. Simply make it clear you are not a bank and are not extending credit. If your invoices are small setting up a recurring credit card payment is an option with various payment platforms.
brk··on “CEO said a thing” journalism
The thing this article does not cover is that the average journalist has no sway. Most readers don't want the opinion of some random person covering a space, so "CEO Said a Thing" is the headline that draws the reader in. Many times the journalist also is not getting paid enough to inject any sort of counterpoint or unique perspective. This just seems like the natural outcome of the click-whoring online "news" structure we've created.
brk··on Font Smuggler – Copy hidden brand fonts into Google Docs
It doesn't matter on the corporate identity either.
brk··on Ask HN: Remember Fidonet?
I remember, and ran a node for a while. I think it is alive today in spirit through forums like this. The original needs and limitations that drove the creation of Fidonet have been dead for decades though.
brk··on DARPA’s new X-76
I don't understand the purpose of the Xenon taillight.
brk··on Show HN: Tanstaafl – Pay-to-inbox email on Bitcoin Lightning
How is the whitelist built and managed? I have several thousand emails that I would need to whitelist, many that don’t email me regularly, but I wouldn’t want them to get hung up or worse receive an auto response that I expect them to pay me.
brk··on Ask HN: Who is hiring? (March 2026)
Let me know when you need sales/marketing/channel ownership.
brk··on iPhone 17e
Recently?
brk··on iPhone 17e
Considering that no major phone or carrier has embraced that model why would you expect it to suddenly appear here?
brk··on Sub-$200 Lidar could reshuffle auto sensor economics
Nothing works perfectly in all conditions and scenarios. Sensor fusion has been the most logical approach now, and into the foreseeable future.

Computer vision does not work exactly like human vision, closely equating the two has tended to work out poorly in extreme circumstances.

High performance fully automated driving that relies solely on vision is a losing bet.

Sources are primarily boating forums, dockside conversations, etc.

In theory your boat in right in the sweet spot of recommended power range at 60HP. I don't know all the background on it, so all kinds of potential problems, but I would wager that "propped wrong" is unlikely to be the core culprit.

I'd start by getting it weighed and comparing your loaded weight to manufacturer specs. USCG requires positive buoyancy for hulls under 20'. This is typically achieved with using expanding foam in hull cavities, and that foam can have a tendency to absorb and hold water if the boat develops any failure of the seals around the bilge areas that are foamed. Reports of poor performance are very common for these sub 20' hulls because of waterlogging. If not a waterlogged hull, you might also just have too much stuff on-board.

To a lesser degree, a bimini can also have an adverse affect on speed/planing, if it's acting like a parachute. Not sure if you have a bimini, but if so it's worth trying a run with it up vs. down.

I'd also look at how your outboard is mounted. It's not clear if it the outboard from the factory, or if the boat has been repowered. Outboards being too high, too low, etc. are pretty common issues that can also majorly impact performance.

That's a few thoughts that comes to mind off-hand.

brk··on Voith Schneider Propeller
Yes and that range is at higher RPMs where the Sharrow props have reduced benefit.
brk··on Voith Schneider Propeller
For marine applications dual drives are common as it enables better rotational control for maneuvering. The redundancy aspect is also a factor, but moreso for applications where you are going to be far from shore. For tugboat and ferry type applications, where these drives are most common, that is less of a concern.
brk··on Voith Schneider Propeller
For the most part the Sharrow props have not proven to be much of an improvement, particularly for the high price.

The tests that have shown "significant" improvements have frequently compared the Sharrow to a sub-optimal prop. Feedback from many actual users is that the gains are moderate over a narrow RPM range.

brk··on WiFi could become an invisible mass surveillance system
I don’t think anyone has ever tried to publish something disproving all of the gait analysis claims. That would be an odd sort of thing. But I have not seen anything come to something that we could call productized and reliable. It’s relatively easy to publish theoretical papers. Much harder to show it working reliably in the wild.
brk··on WiFi could become an invisible mass surveillance system
Resolution and positional accuracy are very poor. It’s more like ‘an approximate bag of water detector’.

Gait analysis is complete fiction. Especially with a non-visual approach like this.

brk··on I now assume that all ads on Apple news are scams
I am surprised you could look at that page and expect to receive a quality product. The images all look like really low grade AI-generated renderings. The mug in the cupholder and the giftbox image in particular don't stand up to even casual scrutiny.

Not trying to make your situation worse, I just find it interesting what these sites are able to get away with to get people to part with their money.

brk··on Lessons learned shipping 500 units of my first hardware product
FWIW I've had good luck with Intertek https://www.intertek.com/ for most testing and certification processes across a variety of products.
brk··on What's up with all those equals signs anyway?
Wait, now we have to deal with Carriage Line Return Feeds too?

I wonder if the person who had the idea of virtualizing the typewriter carriage knew how much trouble they would cause over time.

brk··on Richard Feynman Side Hustles
I think this was primarily about speeding up the measurement time. With just two electrodes you had to wait for the device to achieve equilibrium with the material being measured. If the concentration of oxygen on the probe side of the barrier was higher or lower than the material side you would get false measurements, particularly in low oxygen scenarios because you have oxygem trapped in the probe.

By keeping the state of oxygen inside the probe constant and replacing consumed molecules you now can measure almost instantly.

brk··on Richard Feynman Side Hustles
You definitely don't have to be god tier anything, you just need to know at least a little more than the companies you are consulting for.

This kind of work has been my primary income for the last 4 years or so. Nowhere near on the same level as Feynman, but I know enough about enough other things that I get a lot of reputational referrals.

brk··on Tesla ending Models S and X production
It will be interesting to see. At this point, I think much of what is coming out of Tesla in both words and actions is stock price theater. They "fired up" a Cybertruck production line and we all see how that went.
brk··on The tech market is fundamentally fucked up and AI is just a scapegoat
Factory overhiring can happen easily by adding speculative 2nd and 3rd shifts. No need for extra equipment, tooling, or physical capacity.

Lines with specialty equipment and tooling can also often be sped up. That can allow for other jobs to be added to all the functions that support the processes involved before and after the specialty equipment.

New employees also often require training and some apprenticeship time, meaning they can get hired ahead of actual demand.
