Norwegian news seem to think this is a semiconductor manufacturing plant.

They probably did a direct translation of this:

«Stargate Norway is planned to deliver 230MW of capacity, with ambitions to expand by an additional 290MW. The facility will target to deliver 100,000 NVIDIA GPUs by the end of 2026, with the intention to expand significantly in the years ahead.»

Makes it sound both like a power plant and a semiconductor factory..

I live in europe and have taken overnight trains to various destinations and they've all been nice - quiet, smooth, good food, decent nights sleep...

I've also taken them in Egypt and Morocco and they were loud, jerky, and smelly...

When I see pictures of trains in the USA they look very old and look like the locomotive is actually pulling the train vs providing electricity to each individual car's motors. This was the problem in Egypt and Morocco - the engine accelerate and all of the cars get jerked and when it slows down all of the cars get jerked again, making it hard to sleep.

European sleeper trains are usually also powered by locomotives, and the individual cars don't have motors, so I think the jerk motion you've experienced is caused my poor couplings or something else.

Wouldn't be more efficient to just ban ICE cars? I'm sure they create way more pollution than leaf blowers.

Here's a quote from the article:

> In 2017, the California Air Resources Board issued a warning that may seem incredible but has not been seriously challenged: By 2020, gas-powered leaf blowers, lawn mowers, and similar equipment in the state could produce more ozone pollution than all the millions of cars in California combined. Two-stroke engines are that dirty. Cars have become that clean.

(1) Doesn't that severely weaken the frame? It looks flimsy, and even if the lock part is attached back, it does not look like as strong as a welded joint.

(2) The levers introduced by the long straight tubes seem to open up a physical way in. Imagine twisting the bike off the post.

(3) Once LPL shows how to open that lock, one might want to swap it for a better one. Is that possible?

The downtube is mostly subjected to stretching forces. But maybe it does lose some stiffness compared to a normal bike.

bjornorn commented on Myopia treatment 'smart glasses' from Japan to be sold in Asia asia.nikkei.com/Business/... · Posted by u/brian_herman

lultimouomo · 4 years ago

I'm glad that it worked out for you.

I ordered slightly undercorrected glasses (-2/-2.5 instead of -2.25/-2.75) exactly a year ago to try the same, and it did nothing for my myopia. I use the undercorrected glasses all the time, except when driving at night and when playing sports, and nothing has changed. I still use them all the time because the cheap frame I chose turned out to be very comfortable, more than the expensive one from my regular glasses.

At first I had some hope because for the first days using the undercorrected glasses I would end up with a strong headache in the evening; when this passed I figured that maybe my eyes had begun adjusting. But every time I try the regular and undercorrected glasses side-by-side, I see noticeably better with the regular ones (I sometimes test this just by eyeballing something afar, or by reading a home-printed Snellen chart 3 meters away).

I figured some people have glass-induced myopia, and some people just have myopia.

Could it be that it helps you long term in that it keeps you from needing even stronger correction?

“When the phone system went electric”

I have trouble getting past this sentence. Did they mean “digital”?

bjornorn · 4 years ago

I guess they're referring to the upgrade from manual to automatic switchboards.

I agree that you're probably correct that Wout did win. However, I don't think you've correctly lined up the center of the wheels, nor the rear of Wouts wheel.

For the center of the wheel, Wouts looks slighty too early and I think due to the larger size of Pidcock's hubs it's hard to determine the center here too. As for the rear of the wheel, Wouts gum wall tyre is hard to see.

So all in all, it does seem likely Wout held the lead. However, a well times bike throw can change a riders speed momentarily for a short period of time and based on the video Pidcock's bike throw was significantly more effective than Wouts. So while I'm not going as far to say Pidcock would have won, I'd say there is a chance Pidcock had the lead momentarily, and that moment may have occurred as Pidcock crossed the actual finish.

bjornorn · 4 years ago

Assuming Pidcock was in front on the actual finish line, his hub would have been about 5cm in front of the photo-finish line. That leaves about 3ms for him to finish the bike throw and return his hub behind Wouts hub. Seems like a stretch, but still a possibility :-)

Maybe you could also look at how deformed the wheel perimeter compared to a perfect ellipse to estimate the speed at different points?

EDIT: Or you could calculate whether it's humanly possible to move a bike a few centimeters forwards and back again in about 15ms, which I think the hypothetical bike throw must have been for Pidcock to be the actual winner?

oh-my-zsh tricks to blow your mind seems like a more appropriate title. I tried some of them in zsh, and they didn't work, because they assume you also installed oh-my-zsh.

Nice. Here's a similar personal story with a PSA that sometimes blurring is NOT sufficient.

A friend of mine posted on Instagram a picture of a U.S. visa (or something similar; it was probably five years ago) to announce her trip to the U.S., and she took care to blur out sensitive information such as her passport number. But a Gaussian blur is easy to reverse and I successfully unblurred it and told her my discovery. I didn't use any specialized software; it was just Mathematica with its built-in ImageDeconvolve function with guessed parameters for the Gaussian kernel.

I personally recommend blacking out (add a black rectangle) instead of blurring, and if it is a PDF, convert to an image afterwards because too many PDF editors use non-destructive operations to add a new object instead of changing what's underneath.

Did the blog author actually un-blur the booking reference though? He states he tried to un-blur the barcode, was unsuccessful and then realized the booking reference was right there in the picture. Nothing about un-blurring it.
