    Only sunlight is real light. The others are just very inadequate fakes.

    You see here the wavelength profiles of sunlight, a white Led light, and fluorescent light. Superficially, all three appear to be white light. But just look at the components of that light. The fluorescent creates its white light by mixing a very specific red, with a very specific green and a very specific blue. Hence the three peaks. The other wavelengths are almost completely absent. The Led does something similar. https://www.researchgate.net/figure/The-power-spectra-of-the-standard-sunlight-AM15-a-white-LED-used-in-this-work-and-a_fig1_320346591

    https://www.ledsmagazine.com/leds-ssl-design/driver-ics/article/16695240/proper-driver-design-eliminates-led-light-strobe-flicker-magazine What a flawed paper. It makes the false statement that flickers above 160 Hz are undetectable and cause no health issues. The problem occurs during eye movements called saccades. We execute thousands such eye movements throughout a day. "Saccades are rapid, ballistic movements of the eyes that abruptly change the point of fixation. They range in amplitude from the small movements made while reading, for example, to the much larger movements made while gazing around a room." The stroboscopic effect during a saccade only disappears if the light has a flicker above 3000 Hz. Which few lamps are designed for. https://www.google.com/amp/s/theconversation.com/amp/the-scientific-reason-you-dont-like-led-bulbs-and-the-simple-way-to-fix-them-81639 Flicker is only one problem of fluorescent and LED lamps. You have the other problem: blue light. Some LEDs emit a massive proportion in the blue end of the light spectrum. This causes a distortion of your circadian rhythm and hormonal changes. Then there is the third problem. The light output of these man made luminaires have frequency gaps, i. e. some portions of the spectrum are underrepresented. The light is just artificial and totally not like sunlight. An analogy is infant formula vs breastmilk. Artificial light vs sunlight is like that. So, design the space you spend time in such that you can work and live with sunlight alone when sunlight is available. After dusk, use a filament light.

    I made some changes to the loft today.

    How does a great architect build his own office? He builds it for the sense of well being of the occupants, instead of trying to impress visitors, or to appear "professional". You see lots of wood, foliage, and sunlight.

    Yeah, a sewing machine!

    http://theconversation.com/leds-could-be-harmful-to-health-the-eu-halogen-ban-will-make-it-worse-102589 What an illuminating article. By Professor of Psychology, University of Essex, so this is not a quack who wrote it. I completely identify with the effects of magnetic ballast driven flourescents, and whenever I am in the lighting department of IKEA, all the LEDs there give me eyestrain. At home, I use incandescent bulbs. At the cutting table, too.

    I'm making the editor of the above movie a velvet jacket ensemble for the red carpet premiere of the movie. He was once involved with the visual effects of Life of Pi.

    In the foreground is Aali, a UM Economics student who is my part time dispatch boy and general shop assistant. I'm figuring out a way to dispose of the sofa. I also just bought the lens whose box is on the oak table, the highly esteemed Voigtlander 40mm f1.2 in Sony E mount.

    Today, we moved the workshop from the loft to downstairs. The ceiling is taller, there is more light, and it spares me trips up to the loft.

    I can't remember the last time I chalked and cut cloth for trousers. Must have been ages. I even sewed the baste myself, which took an hour. Previously, it wasn't possible for me to take a picture like this because the cutting table was too small. This new cutting table gives a complete view of the lay.

    I just bought four of the above from Lazada. They're steak presses. 8"X4". Perfect as cloth weights on the cutting table. As far as I know, I'm the first to use steak presses as cloth weights. Let it therefore be hereby documented.

    So I called Ah C. His voice sounded like someone I could work with. He's currently living in a small town away from KL. Resting, he said. I told him the deal: He gets paid such and such per jacket, and he must work in the shop. He balked at working in the shop. Can't I work from home? he asked. I said he must at least work three or four months in the shop before he gets to work from home. This is so he understands our way of doing things. He really disliked the idea. I said this is a non-negotiable requirement. Well, he said, what if I drop by and you explain to me your requirements. I'll understand with a single look, he said. No need to spend months in the shop, he said. Obviously, he will understand nothing with a look. These are the dumbest class of people I've met in my life. I need them in the shop to learn the meaning of personal standards, which none of them have any. I need them to learn the meaning of specification conformity. I need them to see, with their own eyes because they will not believe it otherwise, the thoroughness with which the garments are fitted and the consequence with which we edit the patterns. There is no room for them to interpret anything, especially since they are retarded. Their job is to follow exactly what we patternmakers have specified. Something they almost never can do. If they can't follow, they have to seek an explanation from us instead of doing their own thing. He also needs to be here for me to dispel the many superstitions he has. He thinks he knows tailoring? Working here will show him an entirely new world. He really wasn't keen on working in the shop. I said that's the deal. Call me if you want it.

    I just saw Carrie Lam's latest press conference. I finally understood why the situation in HK. Why the persistent unrest. She's a charisma-less bureaucrat. Instead of a leader of the people by the people, she's an administrator installed by Beijing---who moreover evades direct questions in a public forum. She is completely out of her depth. Beijing is now already looking hard for her replacement. Her successor will be more popular with the people. Someone who sides with the people of HK without alienating Beijing.
