When David Chapman's "You need more lumens" article came out (which is referenced in the original post), I was on the verge of building a similar setup but at some point read similar concerns on light therapy. Not necessarily effects on circadian rhythm, but retinal damage from staring close to the amount of light.

From https://meaningness.com/metablog/sad-light-lumens : "The clinical studies were done with 10,000 lux provided by a bank of fluorescent tubes in a box that directed most of the light forward. Very roughly, if you are a couple feet from a box like that, 1 lumen produces 1 lux." It'd be interesting to see studies that have these lighting setups but don't involve staring towards them.

The setup that I'm happy enough with: a set of LIFX bulbs in normal light fixtures. They seem to put out more lumens (1100 lumens) than other color-changing led bulbs. If you don't want 'smart' lighting but still want the ability to change color temperature, Philips makes "SceneSwitch" lights (800 lumens) that will cycle color temperature based on turning on/off.

I'm so thankful for the civilization we're living in. We take if for granted, but most of what we do is due to the fact that we have so many technological abstractions in so many aspects of our lives. Like just eating a breakfast in the morning would not be as good/easy 50k years ago.

On a more personal note, I'm thankful for having stopped checking facebook since about a year now, and feeling better, having more time, and building my own company.
I am thankful for close family;
an opportunity to work on a project 'the right way' and learn lessons the hard way without extreme risk;
a sound church with faithful and caring teachers;
and dear friends that have meant and continue to mean the world to me through some very difficult times.

Practical CX – How to Develop Personas for Marketing
Wind is never going to make an airplane experience this level of loading. Think about it: an airliner going 900 kilometers per hour is flying into an apparent headwind of 900 kilometers per hour, much faster than any windspeed it is likely to encounter. The fastest winds that an airplane has to deal with are the tradewinds.

The biggest risk to aircraft from high winds is during landing and when on the ground. On the ground these forces are not going to cause a crash (for obvious reasons) and during landing the bigger risk would be a wing strike or ending up next to the runway. In neither case would the strength of the plane as observed in these tests be a huge factor.

What would cause such loading is a long dive or fall and subsequent recovery:

There are places on the moon where there is quasi permanent sublight. These places also have some ice and are perfect for a moon base project.

Although not “eternal” in the original sense, they are sunlit for extended periods, well beyond the typical lunar day-night cycle.

What is the significance of such features? Permanently lit areas of the Moon are important for future habitation and use of the Moon for two principal reasons. First, these sunlit areas are prime locations for the establishment of solar photovoltaic arrays. The constant sunlight here means continuous generation of electrical power using solar panels. This solves one of the most difficult problems of lunar habitation, survival during the 354-hour lunar night. Prior to the discovery of the quasi-permanently lit areas, we imagined that the only feasible power source to survive this long night was nuclear reactors. Such a power system does not exist and would require several tens of billions of dollars to develop. So sunlit zones allow us to go to the Moon and stay there without this expense and technology development.

The second advantage of a sunlit area is that it is thermally benign. The surface temperatures at the lunar equator and mid-latitudes depend almost entirely upon incident solar illumination and range from less than -150° to over 100° C, a 250° temperature-swing over the course of a day. In contrast, the surface temperature of these quasi-permanent lit areas is nearly constant – a nice, toasty -50° ± 10° C. This simplifies the thermal design of surface habitats and equipment and greatly relieves the energy required for thermal control at an outpost.

The sunlit areas of the poles occur in close proximity to high concentrations of water ice and other volatiles at the poles of the Moon. Their presence indicates the lunar poles are the best places we have found off-planet for human habitation. Constant sunlight, benign temperatures, near the water and a great view – that’s prime real estate.

I'm thankful that I was born in the amazing, peaceful country of Australia with a high quality of life.

I'm thankful my boys are healthy and happy.

I'm thankful for my amazing wife who has always pushed me to follow my dreams.

I'm thankful for the opportunity to work in the software industry, well-paid and not toiling in manual labour, for a company that treats its employees well and is a pleasure to work for.

> I'm really interested in the why. Most people don't seem to care. My in-laws have CFLs in their living room that just feel horrible to me, but they're none the wiser.

My first suspicion would be the spectrum of light emitted, which is mostly reflected in the CRI [1].

CFLs in particular "cheat" by having a couple really strong peaks of very specific wavelengths that to your eyes (or reflecting off a white surface) look like the right color, but when reflecting off anything they have reproduce colors inaccurately -- it's beyond my ability to explain this in detail, but you can see this in some spectrum charts [2].

LEDs vary greatly in this respect, so if you're concerned, you should really be paying close attention to the CRI (and note, as CRI goes up, so does cost).

Better idea ultra high speed megascale nuclear powered cruise ships that never dock. They pull in 1 km from port and use deckside drones to transport tens of thousands of passengers safely on shore in different places all at once or as needed. Speed should reach at least 150mph. And with nuclear power become the domina t coastal form of circuit/belt transport. Not just people but cargo. Nuclear powered merchant marine should have happened. One day it will.

Problem with zepllins is the skin will never be robust...because the bigger and faster the zepplins go the thicker the skin must be and the more difficult self healin smart skin systems will be to invent iterate and operate.

Forget c02 and global warming. Think about simple economics. Next generation systems must be an order of magnitude more efficient in delivering a passenger to his ultimate goal or to any goal. That doesnt always mean only energy efficiency and operation and fuel price per passenger mile but these are strong factors in the equation.

Why would you need a GPS for that?
Light temp is mentioned. It's worth looking at CRI which gives you an indication of how much of the spectrum is represented. E.g. 18,000 watt HMI lights for film are tungsten (3200k) and have a CRI of 99 which is insanely good. But they're 18000 watts. Many high output low watt LEDs have horrendous gaps in the spectrum.

Unfortunately to test CRI you need a $1500 color meter. I'm lucky enough to have one and access to a range of film lights and it's crazy how much CRI varies and the horrendous gaps in the spectrum for some lights.

There are companies creating blood alcohol detection devices that would be an integral part of new vehicles. They can detect alcohol in the cabin air or from the driver's finger. It's only a matter of time before they become mandatory on all new cars, similar to airbags and TPMS.

> I fit the pattern of "Non-24 Sleep-Wake Disorder", with my sleep and waking times drifting progressively later at semi-regular intervals.

This is a disorder now? I thought that's just how humans worked. It's how I work, anyway - if nothing else (like work, or children waking up at 5:30am) forces me to get up at a set time, I'll slowly cycle through until I'm going to bed at sun-up and waking up at 3pm.

Seems to this series converges to 1 for the interval between 0 and 1, and nothing else converges. Is that correct?

EDIT: actually I guess it's more complicated than that. If I'm understanding the order of operations correctly, there's an alternating parity (where n is the number of exponentiations) thing going on with the values between 0 and 1
Ah, I did 4 years ago, and it failed. I learned a lot from that process. But I realized that I am currently (5 years into my software engineering career) don't have the ideas and expertise (in terms of domain specific problems) or the funding. To start my own startup seems 10x harder than just doing leetcode and getting into FAANG.
I started to look into this and from a brief readings of the patents it seems that the magic sauce is Rayleigh scattering by shining an LED light onto a sandwich of two transparent panels and a solid layer of silica aerogel. I couldn't find the thickness of the aerogel layer, which will determine if you get more blue or red light out of the sandwich.

It's quite ingenious, the aerogel consists of silica nanoparticles with a size distribution smaller than the wavelength of the light, leading to Rayleigh scattering to dominate. The non-uniformity of the aerogel structure is what gives it the more nuanced lighting, it lets a bit of yellow light, a bit of this and that, making a non-monochromatic source that resembles sunlight very well.
Definitely not my family. Friends have been far less toxic, and those that know me hold a great amount of respect for me which they've shared with me over the past few years. I'm very thankful that an outsider feels that way about me because my family makes me feel like I'm a zero, when I've worked hard to live up to my own high standards.

I'm mainly thankful for my integrity and solid character that I've built over decades, which requires years of dedication and sacrifice. My persistent and resilient nature through adversity and having continually improved and challenged myself. I've accomplished every single goal that I've put my mind to. I know if the economy and currency collapses, as long as I have at least one hand that I'll survive when others are putting guns to their heads. I can't be broken or demoralized and I can't be stopped, and I'm very thankful for that. Hard work is how we achieve stability in this life, and I can push through work projects no matter how horrible. I'm thankful for that.

I've always told myself, "to stop me, this is going to have to kill me", whether it was a physical or mental task, and I have no idea where this motivation sprang from, it must be genetic because I've been that way all of my life, but I'm thankful for it. Even as I was abandoned and unsupported physically/emotionally/psychologically by family since I was a child and still speaks ill of me behind my back even as I approach middle age. I'm thankful to have worked a tax-paying job since 12, and worked before then under the table (yes, I'm American, born and raised).

I don't think we should be thankful for material things, friends or family because both are fickle. Be thankful for your own character. And if you lack character and integrity, build it even if it requires work, because no one can take it away. You'll be surprised as people notice and respect you, even if you have no money, and strength of character may serve you well in the years ahead during the coming challenging economic times.

Suggests is not demands.

If we discard the requirement to be an increasing function, one recursively defined solution takes f(3x + 1) = 3x + 2, f(3x + 2) = 3 * (3x + 1), and f(3x) = 3f(x), with f(0) = 0.

Or analogously for any way of splitting the positive integers not divisible by 3 into ordered pairs (a, b). Then define f(3^n a) = 3^n b and f(3^n b) = 3^(n + 1) a. This is the general form of the solutions.
Perhaps the myth of the 70 hour google work week is a remnant of their startup days.

My experience was like yours - 35 hours per week ( plus summer fridays and tons of personal days and vacation days ). The only exception was the one startup I worked at where we did put in a lot of work in the hopes of a huge payoff. But even there, we put in 70+ hours a week or two before a major milestone/deliverable/etc.

They are, when used properly.

E.g. to create an SSE register with all 64 bit lanes set to the same value, use _mm_set1_epi64x, to different values _mm_set_epi64x (don't forget to flip the order). No need to use GCC's proprietary __attribute__ ((aligned (16))).

Another portable option is C++ and alignas keyword.

I've been wearing my "good enough" glasses about twenty years now. I know what the perfect vision feels like (I can get 20/10 easily with "right glasses") but that is just too much for me. I just can't live with that, everything is way too sharp. Glasses that give me 20/20 but no more make me feel much better. I always order online nowadays, and never have been subjected to this American "you need prescription/license (= pay) for this" way of dumbing things down.

In general, degrading quality of vision is most likely a symptom of something. Needing reading glasses when you age is the only exception, that is just normal.

Many cars are similar nowadays too, except with cell phone service. It's very aggravating. Even if you don't pay for the 'safety' features and never turn it on. It used to be only on star but now even toyotas have it.
It would be quite nice if there were a single model out there that could be easily hacked and replaced with a speedy interface that does two things, switches HDMI inputs fast and volume control. (And turns off motion blur obviously.) Then maybe you could start throwing other stuff on there.

Risking your life as a policeman or fireman or soldier to serve your community or country I understand. What's the point of risking your life with free solo climbing?
I wish there was something neatly compiled.

Plato's model in the Republic, when read as a manual for elites wishing to control society on every level, is revealing in how people are enslaved through their own lack of discipline.

This clicked, for me, with the physiological metaphor in my previous comment when I realized that self-discipline often follows a path upward from control over sexual desires, to control over hunger, to control over one's emotions (the heart) and on up as you master each lower level.

Conversely, failure to exercise discipline over the upper levels, over time, slides you down into the basest level, like an infant, where you lack control even over your own biological functions. Apply the microcosm of your own self to the macrocosm of society and the same principles are in effect.

College professors have noticed a rapid increase in the portion of students who are clueless about filesystems. This may be because troubleshooting a PC is mostly a thing of the past; today it is common to experience computing mainly as phone apps and Google documents.

Teach about switching directories, having a current directory, using relative paths, using absolute paths, and having a home directory. Teach this via both GUI and CLI, getting students comfortable with the fact that they represent the same thing. If applicable to your OS, also teach about drive letters and the current drive. It's best to teach with multiple file managers and multiple CLI interfaces, possibly taking advantage of Windows Subsystem for Linux (WSL) on Windows 10 and/or a virtual machine. BTW, those are good to learn about too.

Teach about file archives. Many students today are left helpless if an archive isn't automatically handled. Teach about how pure archive formats (tar cpio pax), filesystem images (iso), compression formats (gz bz2), and combined archive/compression formats (zip arj) relate to each other.

Teach about saving files. With many apps doing this automatically now, people can hit disaster when they encounter one that doesn't. Teach about the different places that files can end up when saved, and about why this matters. It is now easy to be unaware that copies of a file might or might not exist in various places, both local and remote. This has implications for privacy, disk usage, network connectivity needs, and recoverability in the event of hardware failure.
