Here in the UK the trend now is to use stronger plastic bags that are more easily reusable as opposed to cloth. We have several in a drawer at home, and I keep one in my rucksack at all times so it gets a lot of use. But I'd be interested to know how much more efficient it is than the cheap thin plastic. While I do my best to reuse it, I'd be surprised if it lasts 100 shops.

But what I think the article fails to mention is that it's not about stopping the use of plastic bags, but more about encouraging their reuse instead of just throwing them away. The idea being that if fewer are produced, fewer are likely to end up in the environment.

Spreading behaviour is so important. Which means it's important to make it "cool" to be environmentally conscious. I think people sometimes underestimate the cool factor when it comes to spreading ideas.

But I can't turn my smartglasses around and show someone the memes I'm looking at. I don't see how it could replace my phone. Compliment perhaps, but having used Google Glass Enterprise I don't think it's as big of a game changer as you might think.

I think the big reason that Magic never ramped up so much is because of the fact that it's a physical pack. You can only buy however much is in stock (at most) and even when you order a booster box or fat pack online, it still has a delay before it arrives. With the online model it's really easy to just keep pulling the lever over and over again and getting an instant response.

My experience with this is related to music, but since software engineering is similarly flexible with regards to qualifications, I'm sure it could apply.

I'm totally self-taught in music, using mostly books and the internet to begin, then just real world experience playing in jams and gigging for free with strangers. Eventually, I was able to fund myself in university through my post grad just by playing bass in a band. Auditions where you can show what you can do(by literally playing for others) isn't too dissimilar to coding exams in interviews, as well as having a "portfolio" of sorts.

So I would say that self-education is definitely useful. Although I've not experienced it in the world of software, I have first hand experience in it's usefulness elsewhere.

Hello, not a direct reply to your questions but you'd be right to say that most photos you see of space are inaccurate for colour. We call them "false colour" images.

Typically what you'll do is take images of the same object with a telescope at a variety of different wavelengths. The basic pattern is to use 3 images, and then use each one to represent a different colour from red, green and blue. Then layering one on top of another you can create an image that looks like the bright and colourful ones you typically see of nebula/pulsars etc.

This way you get lots of detail, since different parts of the celestial bodies are only visible at certain wavelengths. So a single wavelength image would be over saturated with certain effects.

So even though these are technically "false" colour images of space. There is a scientific reason for doing it.

Not saying that the photo in the article is false, I think it's just had a long exposure time.

Anyway, hope this helps understanding of astrophotography in general.
