When you talk about what is the rate of a clock, say, near the surface of a black hole, it’s going to be quite different from the rate of a clock here on Earth. So there isn’t even a common time in the entire universe. Well, isn't th

It's things like the square brackets and triangular brackets, e.g. def naive_convolve(np.ndarray[DTYPE_t, ndim=2] f, np.ndarray[DTYPE_t, ndim=2] g) I know what this is for, but I have no idea how this is implemented - is it some sort o

When I've tried to use Cython I've not enjoyed it. I feel like I'm invoking a load of barely comprehensible copy and paste magic if I need to use numpy arrays. I imagine it would be possible to understand this stuff, but I ne

Text is great, but graphs and diagrams are often better for representing certain kinds of information or relationships. When I read a scientific paper, the figures are often what I look at first after the title, sometimes even before the ab

The saner way to implement this bash feature would be to have a single environment variable containing inherited shell functions. A special prefix is an alternative, but a bit harder to filter.

zfs can sort of grow by adding vdevs, as you say, however it's pretty wasteful due to the new parity drives It was much more efficient to expand the mdraid raid 6 and expand the btrfs onto that. The other backup server does use zfs (al

I've setup btrfs on software mdraid (raid 6) as a backup system (not the only backup!). You still get the checksums and snapshotting, but not the flexibility of the btrfs raid system. It has the advantage of being easy to grow, unlike

Isn't that a normal orbit around a common centre of mass? As the objects have a similar size the centre of mass appears to wobble as it moves along. In the frame of the centre of mass, the objects would just go round in standard orbits

Yes. Personally, I don't like the italic fonts. They remind of those vector fonts which came with Windows 3, which appeared to be drawn using lines. I think the v.15 italic looks better than the v.32 final version.

It's easy to make a USB device to randomly type dangerous things, open URLs and download, then start applications (anything you could do with a keystroke). That sort of thing is achievable with an Atmel chip wired to a USB plug. See h

Unfortunately I have to correct page proofs of papers back from scientific publishers using Adobe Reader. This is going to make things tricky unless I have a WIndows machine.

(/me waves back at jgraham) Absolutely right - ASTRO-H brings new capabilities - high spectral resolution in X-rays which we don't have now. It's pretty exciting. Beyond that, here in Europe, the European Space Agency has now

I've worked quite a bit on this object. The Perseus cluster is one of the most interesting galaxy clusters in the sky and is the X-ray brightest (and so well studied). There's star formation, bubbles of relativistic plasma bubbles

Interestingly, it picked up Welsh English for me, even though I only lived there for about 10 years when I was little. I only know a few Welsh words. I then moved across the border into England.

It's a shame if it has this architecture that you can't access a pipe in the same way as a socket using the traditional C API. There's a whole mess of handles, C files and the really nasty self-incompatible MSVCRT.

There is also numba, http://numba.pydata.org/ , which uses LLVM to compile annotated Python code, although this is more limited of course.

I'm not sure it's the single inheritance people from other languages might understand. Perhaps I'm misunderstanding things as I've hardly used the languages, but there are links like http://thenewphalls.wordpr

I'm no expert, but each user can create an xpra session, which they can connect to remotely by ssh. You just need to install it and provide ssh access. I don't know whether other options might work. x2go might be an alternative, w

I was interested in Julia until I discovered that it doesn't allow useful things like object-oriented inheritance (unless you go down some complex metaprogramming route). Multiple dispatch is indeed cool, but for some types of systems

Well, there is xpra, https://www.xpra.org/ which allows disconnection and reconnection of X apps. It's pretty good when you get it to work.

I was interested until I discovered Julia doesn't have a useful form of OOP inheritance. Ok, you don't always need it, but for some things it's indispensable (e.g. using widget/window systems).

I would never buy a new phone unless it has an SD slot or perhaps 64GB of storage. How useful is the cloud when you're literally above a cloud in a plane? That's mostly when I use my phone for music playback.

I'm not familiar with the bounds checks in rust, so that sounds a bit more reassuring. However, I could imagine logic errors if people assume they have a certain size, but they don't, as I assume you don't trap wrapping and s

I understand that there is probably a performance motivation for having int/uint having machine-dependent sizes. However, it seems to me that having different sizes on different platforms is a potential security hazard if the programme

Unfortunately there's no way in knowing whether a Python 2 string (str, not unicode) originating from the module should be interpreted as a bytes string or text string. Python 2 doesn't have the clean separation between bytes and

Surely if the human body were a simple machine, as some people argue, then you would be running at a deficit? Any excess energy would have to be stored. In reality, however, the body can adjust to a range of energy input and allow you to ru
