yeutterg··on Notion Calendar
I think it's only the "Share availability" functionality. You can drag times you are available, then it copies text to your clipboard like this, plus a booking link:

Would 30 min during any of these times (all in PST) work for you?

- Tomorrow Thu Jan 18, 3-5:45 PM

- Fri Jan 19, 12:15-5:45 PM

- Sat Jan 20, 8 AM - 5:45 PM

You can just let me know or confirm here: [link]

What's nice is that you can also change the time zone so the other person sees the suggestions in their time zone.

I don't think you can just do a generic scheduling link like Calendly, you have to pick the times first.

yeutterg··on Google Drive misplaces months' worth of customer data
That’s very fair. I totally recognize that Microsoft has a lot of half-baked me-too products to round out the suite. We are going to do a full evaluation before switching (if Loop ever gets enabled) to see if, despite the limitations, this improves collaboration, or if it just creates as many headaches.
yeutterg··on Google Drive misplaces months' worth of customer data
This happened to our business about a year ago. Many random files went missing from GDrive. Eventually many turned back up (usually after a few weeks or months), but in the root folder instead of the folder the files were actually organized in. Google support told us we were crazy.

As an aside, we are looking from moving to a Google + Slack + Notion to OneDrive + Teams + Loop. What is appealing is the ability to collaborate more directly on files and “Loop Components” directly in Teams. But we’ve been waiting for 2 weeks now for support to help us enable Loop, because the instructions in the Microsoft docs aren’t working. They are working on it, which makes them better than Google in our experience, but it has been too slow. Maybe we have to upgrade to premium support?

yeutterg··on Ask HN: What's the coolest physical thing you've made?
Building a hardware business is hard, but it teaches you a lot about product management, supply chains, and empathy.

A few years ago, I launched Bedtime Bulb [0], a light bulb meant to be used before sleep. Since then, my team has reached 10s of thousands of customers, and the reception has been overwhelmingly positive.

It hasn't all been rosy, however. We learned a lot from customers about where the product fell short and what features were missing. We had to pull the product from some markets due to performance issues. We learned the hard way about customs issues, damage in shipping, and much more.

Unfortunately, hardware has long and expensive iteration cycles. But my biggest advice would be to stick with it and continue to learn if you have some feedback from the market that this could be successful. My biggest role models both went through long periods of failure: James Dyson's 5,000+ prototypes and Tony Fadell's years of building ahead-of-their-time products.

And stick with it we did. We are going to release a new version of the bulb in coming months that fix all the issues of the previous product, as well as introduce some new features we think will move the lighting space forward. And we are combining our vision and additional feature requests to release even more advanced products.

yeutterg··on The Boring Company will dig a 68-mile tunnel network under Las Vegas
The future Brightline station, Harry Reid Airport, the Strip, the Art District, and Downtown/Fremont St are practically in a straight line, yet the transit options in the Las Vegas area are fragmented and limited in frequency today. It's baffling to someone who lives and has lived in places with relatively good transit (San Francisco, Philadelphia, Munich, and Berlin) as better transit would be so easy to implement with existing, "boring" transit solutions.

While the idea of cars in tunnels is questionable at scale, perhaps the Boring Company tunnels could be retrofitted with automated people movers (like you see at airports) or some form of small light rail in the future.

I am for the project if it exposes the insanity of running cars in tunnels with higher demand, and then people vote to replace it with rail in the tunnels. But wouldn't it make more sense to do one of the following? - Run more frequent Deuce buses up and down the strip and send them to the airport, potentially in a dedicated lane (BRT style) - Extend the monorail to the airport, or build a cheaper rail system between the airport and the MGM monorail station with a cross-platform transfer or similar - Then build a second rail line running from the Brightline station to the airport, then running up the west side of the strip from the Mandalay Bay to the Arts District and downtown

yeutterg··on LED lighting badly suppresses human melatonin production at night
Yep, we're planning for it by Q4. If you drop me a line at hey [at] bedtimebulb [dot] com, I'll make a note to reach out directly when it's available. Thanks!
yeutterg··on LED lighting badly suppresses human melatonin production at night
Hey, super great post. Light and health is the topic I care most about, so much so that I created the aforementioned Bedtime Bulb product to make it simpler for people to get the right light at night. I also put out a YouTube video series [0] covering the modern history of lighting, although I haven't finished it yet.

We posted as many specs and graphics as we could for Bedtime Bulb on our tech specs page [1].

We're also working on a new Bedtime Bulb v2 that we'll launch in early Q3. More details to share once our patent is submitted, but it will have an improved spectral power distribution, much wider dimmer compatibility, improved reliability, and even better flicker performance. Our understanding of recent research is that there's more to it than blue/green light and flicker, and we'll apply those understandings in the new product as well. If you want to stay informed about that, feel free to reach out or subscribe to our newsletter.

Keep it up!

yeutterg··on Circadian lighting with Home Assistant: Like f.lux, but for your house
To be clear, I don't think companies should be focused on average users. At least not for a while (until there is sufficient education and agreement that this is a problem, if that ever happens). The market is all about early adopters for the foreseeable future.
yeutterg··on Circadian lighting with Home Assistant: Like f.lux, but for your house
We've worked on similar circadian products, and I have a similar setup at home. IMO, we're getting closer to the time the market is ready. The main learning is to release MVPs and continue to gather feedback from/build a relationship with the core early adopter market. The market is small, probably in the tens of millions of dollars annually, but the right solution is going to be easy to setup/use with a good UI, and priced at a slight premium over other lighting (but not exorbitantly).
yeutterg··on Why doesn't Stripe use Stripe Billing?
US. Maybe it's better in other markets.
yeutterg··on Why doesn't Stripe use Stripe Billing?
Slightly off-topic, IMO Xero has really gone downhill. The Yodlee integrations with banks fail so often these days, it makes it hard to use the product at all. When you refresh a bank/credit card feed or log in for the xth time, you have no expected timeline as to when the feed will update or whether it will even work. There are multiple buttons to reset a feed, and they do different things.

It's nearly impossible to just log in and reconcile all your accounts because you are always fighting with unconnected bank feeds. This degrades the core value prop of making it easy to stay atop of bookkeeping—now I always have some form of "accounting debt" these days.

I got so frustrated that I am in the process of migrating my personal account to Tiller + Google Sheets, and I'm still looking for a solution for our small business account.

I agree about the billing issues; I waste time figuring out where the invoices live in the product and manually posting them. Otherwise, the product would be fine if outdated, if it wasn't for the unreliability of Yodlee.

yeutterg··on Ask HN: Any Sales Engineers out here?
Current SE with a product/entrepreneurship background. The main reason I took the role was to exercise the discovery/talking to customers muscle, which I feel has improved a lot. Mid-term, I see myself going back into product management and startups.
yeutterg··on Ask HN: Who wants to be hired? (August 2021)

I'm a startup founder and product manager (PM/PMM). I have experience in both B2B and B2C, SaaS and Hardware, mostly in the 0-1 stage.

The company I founded is focused on sleep. We have around 30K customers. This is the second company I founded—the first was acquired by a larger player in the same industry.

I also work as a PMM at an adtech company for mobile apps. There, I have built a sales team and worked as a PM on an early-stage product. I am now serving as a PMM focused on growth marketing.

Finally, I have a YouTube channel about product management and tech entrepreneurship.

Where I am looking to grow my career: as a PM in high-growth SaaS/apps. That would likely involve honing the product-market fit until we have something that can scale.

yeutterg··on Ian Knot (2003)
+1. I retie my shoes every time I wear them because I prefer them quite tight, but Ian's secure knot almost never comes untied. I usually only retie while wearing if I didn't tie my shoes tight enough in the first place.

Also on my Solovair boots, I used quick tight lacing [0], which gives you the outer "straight lacing" appearance but also allows you to make the boots very tight without spending 5 minutes to tie them. The main issue with this technique is that the laces can shift, but I marked the center of the laces with a Sharpie to serve as a guide.

yeutterg··on Coffee drinkers display a distinct pattern of brain functional connectivity
What is your experience with coffee? Have you mostly had Stabucks/Dunkin/Folgers and the like or have you ventured out into trying third wave coffees? I recommend getting a drink from a third wave coffee shop if you haven't already.

Great coffee comes down to many factors: the beans, roasting, grind, brew method, and temperature.

A great resource for learning more about great coffee is James Hoffmann's YouTube channel: https://www.youtube.com/channel/UCMb0O2CdPBNi-QqPk5T3gsQ

yeutterg··on Anki as Learning Superpower: Computer Science Edition
Great update. This seems to be very much in line with the note-taking and review techniques of Tiago Forte and Ali Abdaal, but for code.
yeutterg··on Anki as Learning Superpower: Computer Science Edition
Hey Jack, I've always found your Anki guides to be some of the best. I'm curious, are you still using it all these years later?
yeutterg··on Amazon Isn’t the Only Shop Online
Amazon third-party seller here. If a Prime product is showing a long delivery time, try to look for non-Prime offers. You want to find offers that say "Ships from and sold by X," where X is NOT Amazon. The reason being, these sellers have their own fulfillment and may be able to beat Amazon's speed by a wide margin.

We now offer this for our product, and I know a lot of other sellers are doing the same. We used to only have a Prime (Fulfilled by Amazon) offer, but this crisis caused us to adapt as customers were getting 1-month delivery estimates.

We enabled "Fulfilled by Merchant" offers on our account, and I sent some inventory to my apartment (and ordered lots of shipping boxes). Within a couple days, the self-fulfilled option got the "buy box" on Amazon, so now most people viewing our listing will see a delivery estimate of about one week. It doesn't have the "Prime" badge, but we get a decent number of orders through this, enough to survive.

We send out all orders with First Class Mail, and I pack them up around 3PM each business day in order to get them to the post office by the 5PM cutoff. It appears most customers are receiving orders between 2 and 5 days after ordering (including the opposite coast). This is even faster than the time estimate customers see on Amazon, and way faster than Prime.

Disclaimer: your mileage may vary.

yeutterg··on Has the bidet's time in North America finally arrived?
Can confirm that my Toto Washlet C200 does this as well. The water will stop about 2 seconds after you've gotten up if you did not manually stop it.
yeutterg··on Our critique of Behringer's proposed TD-3 variant with Devil Fish functions
I have mixed feelings about it. On the one hand, the original Moog company went through bankruptcy and a lot of changing-of-hands. So the current company is only vaguely related to the original.

But on the other hand, they did come back to life, not only to recreate originals but to create new, interesting designs. So even though the Minimoog hasn't been in continuous production since the original, they do still sell it today.

Plus, the new company is mostly employee-owned. If you're ever in Asheville, definitely check out the factory for a free tour as well as the Moogseum.

On to Behringer. What they are doing is questionable, especially around the Minimoog and ARP, two models that are currently in production by the original manufacturers.

However, I think there's an easier case to be made for the old designs that are no longer in production (e.g. the Juno 106, 808, 303, etc.).

Even though Roland makes some modern products that include the functionality/sounds of the originals or mimic the look and feel, they are still generally based on virtual engines instead of analog circuits. Argue all day long about the sound differences, but synth heads tend to love analog. Korg has done a better job at cranking out desirable analog designs.

What Behringer and Korg are doing, that Moog arguably isn't, is creating desirable analog synths that hobbyists can afford. Yes, they were never this cheap back in the 70s/80s. But it drastically lowers the cost of entry for people just wanting to get started and not wanting to use a DAW for everything.

I'm excited for the 909 clone as that has the best pads to my ears. I'm considering getting a DeepMind, which is inspired by the Juno 106 but different in many ways. I could see a TD-3 in my future. I'm less excited about the Poly D and ARP, but that could be my own musical taste as well.

Related note: why didn't Behringer include a batteries option in the 303 and 606 clones? I see these as almost perfect competition to Volcas, but Volcas have battery options and are way more portable. I know the originals were only hardwired, but still.

yeutterg··on Ask HN: What interesting problems are you working on?
Yep, reducing blue light at night is an important part of the problem, but it's not a panacea. We realize that everyone has different sleep needs, and much of our focus this year will be helping people understand what inputs have an effect on their sleep.
yeutterg··on Ask HN: What interesting problems are you working on?
I've had a few discussions with the author of that article. Not intending to put words in his mouth, but I believe he is effectively saying 2 things:

- The metrics Circadian Stimulus and Melanopic Lux are flawed

- We don't know enough to produce products yet

I agree with him on point 1, especially about CS. The author, and several others, have demonstrated a huge discontinuity around 3500K. The CS model needs improvement.

Regarding melanopic lux, the author says it is more a problem with our measurement and modeling tools. Most manufacturers won't provide a Spectral Power Distribution, but this is starting to change (we do). There is at least one clinical trial in progress that is testing this metric directly, and several experts think it shows a lot of promise.

With that said, new research on blue vs. yellow/orange opponency is coming out. Basically, we're trying to figure out contribution of the visual system on top of melanopsin. I'm not sure what to make of it yet, but I think we'll find out much more in the next 2 years. We probably need a better metric than melanopic lux.

On point 2, I agree that our knowledge is changing. But it takes a number of years for standards to be developed, much slower than the rate of technology improvement. We are paying attention to all the new research, but we based our design on our best understanding of the research to date.

We know that we can really only attract early adopters at this stage who "get" it, and that most people are going to wait and see until things are more standardized. But we are effectively able to do mini-experiments with our customers, which can lead to more insights/avenues of experimentation.

Case-in-point: f.lux. Research has shown that it is somewhat effective on its own, but combined with dimming, it could be quite effective. That's actually what we're doing with our product—controlling both the spectrum and intensity. And f.lux is able to run experiments with a portion of their users to advance our understanding.

Basically, my opinion is that we have to start somewhere, and we believe we have enough evidence supporting that our solution is "better than nothing." We were able to prove that there is enough of a market for these types of solutions already, even though our knowledge is still evolving.

(edited for a paragraph spacing typo and a 2nd time for a grammar issue)

yeutterg··on Ask HN: What interesting problems are you working on?
Working on the problem of "blue" light affecting circadian rhythms and sleep. We launched our MVP, Bedtime Bulb [0], in 2018, and it's now the most popular product in the category. We're expanding out of North America to Europe in the next couple weeks.

We've had a ton of great feedback from customers, and we are working on several new sleep technologies that we plan to release this year.

It's also been interesting to apply the lean methodology to hardware. Iteration cycles are long, but I'd argue that lean is just as important for hardware as it is for software.

yeutterg··on Gas Lights: How We Erased Darkness from the Night [video]
Definitely! That's where I want to take the series, to talk about the modern health, safety, quality of light, and light pollution concerns. So I appreciate that feedback.

Regarding 5000K fluorescent vs. LED, actually the fluorescent will be way more spiky, with multiple spikes. A typical daylight LED spectrum is a spike around 450 nm, then a drop, then the rest of the colors from green to red.

[0] compares some different spectra, although most modern 5000K LEDs will tend to be a bit higher in the red area. I would say the warm white LED, cool white LED, and daylight spectra are a bit exaggerated/too ideal in this comparison.

What emits most of the visible light in fluorescent vs. LED is actually almost the same thing: a phosphor that converts UV (fluorescent) or blue (LED) into white light. But the actual chemical makeup differs between LED and fluorescent.

There are some new LED technologies that flatten out the spectrum. These typically employ a violet pump (around 415 nm) or some combination of violet, blue, and cyan (around 490 nm). But it's the phosphor engineering that actually does most of the flattening. We're only just starting to see these become available in finished products, however.

yeutterg··on Gas Lights: How We Erased Darkness from the Night [video]
I recently decided to start a new video series on the modern history of light.

You may be surprised to learn that street lighting (as we know it) was relatively uncommon until the mid 1800s. Up until about 200 years ago, new lighting technology developments tended to take place centuries apart. That all changed with the advent of open-flame gas lighting.

In the first video in my Story of Light series, I cover the development of gas lighting, the pros and cons of the technology, and the inventions that led to its downfall. If you know where to look, however, you can still find gas lamps today.

yeutterg··on Sleep Deprivation in NBA Players
If your TV doesn't have any specific blue light settings, you can get an external device like driftTV[0]. Even without a specific blue light reduction mode, I recommend turning down the brightness to the lowest comfortable setting.
