Software wise, we use a standard pipeline that reduces the data from the space observatory into the standard astronomy format (FITS), provided by the European Space Agency. The output is in the form of events - X-ray photons which landed on

I'm the lead author on this paper, so feel free to ask questions! EDIT: I should say the analogy for these kinds of events is like wine sloshing in a glass. The hot X-ray emitting atmosphere of a galaxy cluster would sit calmly in the

Yes - it's a difficult problem. It must be possible to build a better statistical model of each rater, in order to weight their opinions. A first step would be to normalise the rating distribution of each person (e.g. by average and st

The ratings are useless - any author with a devoted following gets endless 5 star reviews and YA books are stuffed with 5 star reviews. The website is clunky beyond belief and never seems to get improvements. The recommendation engine is te

That's weird - it's the other way round for me. With chrome, the fan on my laptop is often running when I have pages open in the background. With firefox, it's cool and silent.

Terrible for those of us who use undervolting to keep their laptop as cool as possible. I hope they allow it enabled in the bios settings.

I wish I could use LibreOffice, but as a scientist the PowerPoint clone is awful. Editing and importing PowerPoint is very buggy and clunky. For example, sometimes bits of slides become uneditable. Also, the default kerning and anti aliasin

Can I plug my Veusz GUI plotting application? It's written in Python, so it's also a Python plotting library. It's more a object-orientated library than matplotlib, so plots are built out of widgets. https://veusz.

Me too - I run KDE on Ubuntu on a Carbon X1 6th gen - it's great. The only annoying bug are horizontal lines in the terminal from the high DPI scaling.

A lot of banks charge here in Germany. My previously free bank has started charging, presumably because of the low interest rates which make it hard to be profitable. A couple of online only banks are still free if you have enough turnover,

Yes - the article didn't mention the massive debt they couldn't pay off and wasn't being extended.

It was mostly their £1.7bn debt: https://www.theguardian.com/business/2019/sep/23/thomas-cook... Without that they could have shrunk or restructured.

We were actually there to see our X-ray telescope, eROSITA, being launched on the Spektr-RG space observatory. Unfortunately the launch was delayed by a month and we didn't get to see the launch that time, but we got to see the rocket

I had the chance to visit Baikonur a few months ago. The place (which is in Kazakhstan) feels utterly remote and the surrounding landscape is amazingly big and empty to a European like me. It was very impressive to get within a few 10m of a

The big problem was its £1.4bn in debt, which really brought it down. Id be careful holding shares in companies with big debt if there's a coming downturn.

I've certainly had fake products from Amazon UK. Certain categories of products are very likely to be counterfeit, while others aren't. For example there were lots of apple replacement headphones which are much too cheap.

They're just high energy particles that interact with the CCD cameras typically used for astronomy. You get a bright point or particle track, as the particle interacts with the CCD producing electrons. This is worse for space telescope

No they're probably not (I'm an astronomer). They're likely cosmic rays. When I've used Hubble data, then the processing uses multiple images to remove the cosmic rays (which aren't in common between images).

I'm an astronomer, and I think you're probably wrong. It's mostly down to exposure. Those little dots you're seeing in the images are likely cosmic rays. Those are removed by combining multiple images, as cosmic rays don

Yes - Goodreads is pretty awful when it could be so much better. The searching is awful, the comment UI is grim and the suggested books lists are poor. The most useful tool I've found for finding new authors is this: https://

Yes - Apple are one of the worst. I truthfully could not answer most of their questions, some of which seemed very US-centric. For example, I've never owned my car and do I really have a favourite colour?

In my experience UK banks are quite a bit better than German, though that's changing. UK has had almost instant payments for several years. In addition most of the German banks think 5 character passwords are sufficient.

I think we have to disagree there. Of course the details about what brings matter together, the opacity, etc, are important, just like anode/cathode design and casing are important in batteries. Gravity's decisively not where the
