My first guess is that the change on the electronic band allows downstream electrical switching of a prism/mirror or other photonic device. So you have a special light signal controlling an electric signal to switch the “regular” light signal. Not sure about the applications for the strong EM field though.

I’ve been thinking about making cheaper cryocoolers for CO2 condensation. I’d love to hear your perspective on other applications :)

Since this is the topic, I'm going to post my own recent experience with Google/Youtube: (also with the hope that a good soul can assist/give pointers)

I have a YT channel with a short-feature documentary film I uploaded 13 years ago (https://www.youtube.com/watch?v=5Nz4N2K64o8). Last year YT started sending emails that channels with inactive accounts will start being deleted. So I have been working on logging on my channel account which is a Google ID tied to an email on my own domain (startingupinamerica.com) on which I still get emails. I still have the correct password to this Google ID, and 2FA was never enabled.

Google will not let me log in, as they insist on sending a verification code to a phone number I no longer own since years ago. Support requests keep sending me to a guide/process that will repeat the same thing again and again and that if I don't have any option that's that. All I get are the emails that "someone is trying to access your account" when I try to login.

I have been wondering what is the resolution in this case, it seems it's either know-someone or going to court (and risk getting banned?).

This is a common misconception. It's something that was discussed orally and taken out of its context and is being repeated today [1]. Besides the fact that NATO is a voluntary alliance and not an empire. At one point Russia was even considered for joining NATO.

The Budapest memorandum however was a written agreement, much more meaningful, though sadly not binding.

Historically, Pantone & Munsell in the US of A.

Pantone is really print-oriented, even if they've surfed on the brand to expand to fashion & cosmetics. That's why the standard Pantone PMS colors don't have whites. Munsell is more general purpose.

But RAL & NCS are also used widely, and will probably both keep going up in popularity for reasons I outlined in my other comment on this thread.

Another aspect in addition to what others said: digital color libraries are generally available for free or low cost.

  - Pantone recently removed its color libraries from Adobe products to make them an additional subscription of $14.99/month
  - Pantone colors are always a subscription on color readers/spectrometers unless you buy X-Rite's high end readers. RAL is available for free on most color readers.
  - NCS is a bit between RAL and Pantone in that regard, they sell an affordable color reader (for its full spectrum capabilities) that includes the NCS library, but it is a paid subscription for other readers, albeit cheaper than Pantone.

RAL is a lot, lot cheaper than Munsell or Pantone (now both owned by X-Rite) and is particularly well suited for Industrial Design.

  - you can get yourself a fan of RAL Classic colors for $16, which are solid colors that include enough grays, whites and colors to get started and cover all basic needs, and that most industrial/finishing shops already have
  - most shops now also accept Pantone PMS C (coated), which cost $260, but Pantone comes from printing and so has no whites, you need to add FHI TPG+TCX (another $260) to get whites. Pantone recommends replacing the fans every 12-18 months before their die age
  - Munsell is a "full" color space so as such it is inherently more expensive (even more so that it is now owned by X-Rite), with a rich history in USDA standards, food QA, science and artists. NCS and RAL "Design" also feature "full" color space, most certainly a lot cheaper than Munsell

Cost is important because everybody in your supply chain need to have the color system on hand: designers, marketing, suppliers, QA.

Curated colors:

  - RAL Classic (216) $16, RAL Effect (490) $70
  - Pantone PMS (2,390), Pantone FHI (2,625) each $260
  - RAL P1 Classic plastics (100 colors + textures): $2,100 
  - RAL P2 Effect plastics (200 colors + textures): $2,700
  - Pantone plastics (1,755): $9,078

Color spaces:

  - Munsell (1,600): $1,525 - $1,625 (Munsell book of colors matte - glossy), cheaper subselections of colors based around neutral, soil, plant & rock colors
  - NCS (2,050): $210, used a lot in architecture/interior design, from Sweden
  - RAL Design (1,825): $160, all its colors are additional to/not in Classic/Design

If you need a few colors, a curated system is more adapted and cheaper, but a curated system with thousands of colors (Pantone) is more expensive and less versatile than a system based on a color space.

As you can see the whole RAL catalog/system of color is designed for cost and so that you can start small and expand, and have enough variety at each level + it has nice features that shows its Industrial orientation such as all colors being solid and textured plastics.

RAL catalog has each system building on the other, Munsell is a color space with subsets picked from it for specific uses, NCS is always the full color space, Pantone is a gigantic, somewhat incoherent curated system that started with printing and expanded into fashion & cosmetics.

Munsell is based around different sectors of industry & science, so color subsets availability, design and price dictate that it is uneconomical for other sectors or more general design outside gov standards. E.g. Munsell even has a frozen french fry color standard book! [1]

There are many more color systems and color spaces, but those are the main ones for which there is wide availability of physical color books around the World.

I am not sure this is the correct take, they happened to have assumed the debt prior. But the building was sold independently for this price at a public auction. They had to do this to find the fair value of the building to deduct it from the debt. You could have bid 6.57M and won if no one bid after. Now they own the building and the remainder of the debt.

What difference does it make? It cost them more than $6.56M in the end but to deduct the building at a fair price they had to auction it and nobody bid higher than that.

There probably are exemptions for emergency or defense applications.

The equivalent today would be 3Dbenchy boats -- "we found an identical boat toy design in multiple sites made of different plastic materials, colors and sizes. It is spread universally around the World cities, found in sites of crafts, leading us to believe it is an idol of a new 21st century religion predominant among workers of the arts and crafts"

The idea is that it could help lower inflation as shelter is a large portion of core CPI. It’s not about lowering the prime rate, but having a lower rate for creation of supply, which would exclude all services (80% of the economy).

Does anyone have a good explanation of why the Federal Reserve isn’t able to have lower interest rates for supply creation activities? It appears that would be a useful tool that would work in favor of their inflation and employment mandate.

Machining & Prototyping shops or "on-demand manufacturers". That involves choosing a region, evaluating the options/making a list, contacting a few and having a NNN ready for them to sign, getting 3-4 quotes for every parts in different MOQs, managing information on a need-to-know basis (to have some level protection beyond your NNN), managing these relationships etc. There is a lot more as the processes move to die/mold making as you go up in quantities and these have their own design requirements & ownership agreements.

And the only thing that seems to be ruining him is the pure software play (Twitter)

I am a Software Engineer like you. I got started in making physical products in 2017 first with 3d printing, and today I do design for manufacturing.

This might surprise some here, but if you can do 100% of the design and get good at it, it's possible to bootstrap a hardware company, even as a solo founder. I know it because I've done it.

However I intentionally started with physical products with no electronics in them. I also tried manufacturing in the USA initially but quickly realized it to be uneconomical and too slow, especially for bootstrapped consumer products.

My advice: 1. make a breadboard prototype @ home & design the product on your computer 2. have prototype parts made in China until you are satisfied with the final assembly 3. once you have pre-order volume, have the molds & dies made in China, import the tooling in the USA and setup your own shop.

The other thing is getting good at Industrial design takes a few years, it's not necessarily intuitive -- you have to understand the processes that you are designing for and get good at making drawings and hiring shops. It won't happen in a year unless you just focus on one part/process, so I would team up with someone who has that experience.

Feel free to contact me, info on my profile, happy to chat & help out.

fun tidbit: the standard was updated in 2013 to replace the chasing arrows with a triangle because of this

I have the reverse issue, I am constantly coming up with creative ideas, so that by the time I am done building idea A prototype v1 (something like what you see in this video) or v2, idea B comes along and distracts me from seeing idea A all the way through. And when the persistence and discipline is there, bills need to be paid, and the distraction is not idea B, but merely some mundane work.

This whole post is an anti-pattern and bad advice. It read as from someone who didn’t go through the growing pains of building complex websites.

This is how we started building websites until things started to break with side effects, conflicting class names, bad introspection etc. and React came to the rescue.

The pattern you want is progressive enhancement and your output to be clean, compact html that’s augmented by JS. Which means build step. Everything opposite to this article’s advice.

Second this, I'd say started being common for Web apps in 2008 and "industry standard" by 2012 in the SF Bay Area.

The feasibility is not a function of the time or number of people. When you remove material, the slightest error is irreversible. By combining error rate, design tolerance bounds and work point size in a statistical model, you should be able to prove that even using the entire known population on earth at the time for several centuries, you would not be able to product near anywhere the number of these specific artifacts found under the step pyramid (40,000). It’s sort of like the problem of enough monkey typing randomly to produce the work of Shakespeare.

The rough shaping is not at issue. The challenge is maintaining tolerances along all axis and constraints on your detail work while using high forces and pressures to work the hard material. Grinding is a good guess for the possible material removal process — and it is up there today for the smallest tolerances using a mechanical process —- watch a video of a jig grinder in action. But what tool is used to hold or insert the sand aggregate at the pressure point? Are you suggesting that the vase is turned? That turning tool would need precise bearings itself to maintain that precision. According to archeologists, Egyptian didn’t even have the invention of the wheel yet at this point. These are all questions that people are looking for answers, and the best way will be to attempt to reproduce an artifact using various methods. I sincerely invite you to contribute by trying to elaborate the entire process that would enable this.

As someone who works with manufacturing, I don’t think it’s silly. Precision is not just a function of time available, manpower and talent, but also tooling technology. Manufacturing a single replica with today’s technology is believed to be challenging — and has not been attempted yet — but hopefully someone will take the challenge soon. There are no serious claims that these can be made with known ancient technology and time+manpower. Your response is often the response of people in archeology who do not understand precision manufacturing with hard materials, and shows how underrated these artifacts are.

Not pre-human but challenging the understood modern human timeline of industrialisation — We have not found the tools, but we may have found the products; in the form of stone-based vases that archeologists attribute to the Early Egyptian Period but are believed to be from much earlier, and would have required tools that have not been discovered yet. The channel UnchartedX make a compelling argument about this hypothesis: https://youtu.be/ixTTvRGk0HQ

I assume it sort of balances out, if properties don’t sell, they may go on the rental market. Another thing is that the renters pool has some elasticity built-in: renters may move with relatives or roommates/significant other.

This 100%. Free public parking in NYC is the elephant in the room that no one wants to address. Tolls won’t fix that. In some areas of the outer boroughs, 40% of the traffic at any given time are people looking for a spot. The city also still hasn’t figured out utilization of the curb for deliveries and drop offs resulting in normalized double-parking almost everywhere. Curb space need to be efficiently priced and this would fix a host of issues — same goes for outdoor dinning, otherwise its value will be captured by landlords anyways.

1. lots of innovation in ICE engines is getting close to production. Cleaner, more efficient etc. This is important even while the industry is moving to EVs.

2. Bambu Labs leapfrogged prosumer 3D printing by 5-10 years. Their printers are becoming the de-facto standard. This will enable all sorts of startups for the next decade.

3. Most iPhones now have a 3D scanner + AI-aided software to accurately scan your body and generate designs is becoming more mature. See also 2.

4. material sciences both new discoveries and new applications for 50 years old discoveries

I think it actually makes a lot of sense, from a computer architecture point of view: (1) total resolution is generally a component of the graphic processing power needed (for straightforward graphics rendering), and so scaling GPU power with displays/resolution make sense (2) placing a GPU in the display lower the demands on the interface, of which Apple has repeatedly hit the limits on

In addition/as a result of these you get some usability and user experience advantages: (a) avoiding degrading laptop performance when connecting an external display without the user having to know about eGPUs (b) no additional box/cables/power mess from using an eGPU

Google generally does not come off to me as having a great customer support culture. To appreciate the scale of the issue, take a look at the hoops and blackboxes merchants who want to be listed on Google Shopping have to go through and all the horror stories online. I did notice on Google Workspace and Google One that they do seem to be trying to improve the support experience.

Citing from https://www.patriotsoftware.com/blog/accounting/price-gougin... > New York's Consumer Protection Law prohibits price gouging during an emergency: What is considered price gouging: 10% or more price increase. When price gouging laws apply: During an emergency. Products or services the law applies to: Necessities.

Say your gross margins on said masks were 50%, you paid $1 per mask and sold them $1.50 plus tax.

Now the same branded masks are $2-3 from the supplier and you cannot legally sell them without losing money.
