Comment Small blast followed by ordinary blast (Score 2) 154

It's quite simple. First, the star underwent a small blast, too small to be detected, in which it expelled a layer of gas. That gas formed a cloud around the star. Then, there was an ordinary blast. What we saw was the gas cloud being illuminated by the ordinary blast.

Comment Get two different lenses (Score 1) 464

Some 18 months ago, I started to have problems reading, especially in darker environments. Reading the menu in some restaurants was getting real hard.

My ophtalmologist proposed to try two different contact lenses (I use contact lenses for many years already). One lens, for my left eye, would have optimal focus at short distances. The other lens, for my right eye, would have optimal focus for long distances.

My ophtalmologist told me that some people love this setup while others just get nausea, so I could try them for a month. If I decided they were not for me, I could replace them with ordinary contact lenses at no cost (but then I would of course need reading glasses). If I liked them, I could keep them.

I kept them. I love them.

My brain automatically uses the eye that's most suited for the distance I'm focusing at. So now, reading from the computer screen, I use my left eye. If I close my left eye and use my right eye to look at the screen, things get a bit blurry.

Similar for long distances. When driving, my brain automatically uses the right eye, so I can see traffic and traffic signs in good focus. If I close my right eye while driving, things get blurry.

This all happens totally automatically. I do not have to spend any effort.

Estimating speeds and distances is still possible. I have no problems catching a ball thrown toward me, and I can still estimate the locations and speeds of cars, cyclists and pedestrians while driving. It seems 3D vision still works when one image is sharp while the other one is blurry.

I use contact lenses, but my ophtalmologist told me this setup works with (single focus) glasses too.

I suggest you propose this setup to your ophtalmologist and see what (s)he says.

Comment Eavesdropper in the middle? (Score 1) 247

An email address travels through several systems between you and the other side. This applies to the time when you fill in your email address in a web form, and even more so when the company sends out emails to your address.

Thus, it may be premature to conclude that the fault is with the company. Eavesdropping may have occurred at any of the intermediate systems.

Comment Such plans already exist for some time (Score 1) 266

Mars One is an existing plan to give volunteers a one-way trip to Mars. The mission will be paid by broadcasting every part of it, starting from the initial selection of candidates up to them living, working and dying on Mars, in a Big Brother like TV show.

After that, one should clean the free space on the disc. If you have no rights whatsoever, the simplest way to do that is by filling up the disc with random files until it's full. Then erase the filler files and you're done.

I do this by creating a text file called 'a' for simplicity, 4096 bytes long, containing only the character 'Z' (which makes for a nice binary pattern). In a DOS prompt, I issue commands like

copy /b a+a+a+a+a+a+a+a+a+a+a+a+a+a+a+a b
copy /b b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b c
copy /b c+c+c+c+c+c+c+c+c+c+c+c+c+c+c+c d

to fill the disc. However, if you even do not have access to a command prompt, multiple copies of any other file will do.

Europe sends data about all financial transactions to the US. Does the US send data about all financial transactions to Europe?

Long ago I thought we were equal. Obviously, one of us is more equal than the other

Sounds nice, but...

What if the wife gives in, you then have kids, and 6 to 18 months after birth (or whatever is the time for vaccination), she changes her mind? I've seen it happen...

What if she changes her mind, tries to re-discuss the issue with her husband, finds she can't convince him, and only pretends to give in. She says she'll bring the child to vaccination, but in reality, she doesn't. She just lies to her husband.

The problem is: if a mother firmly believes that this is in the best interest of her child, and if she believes vaccination poses a risk to her beloved little child, then those feelings are so overwhelming, there's nothing she can do to fight them.

I've seen it happen...
