Does this definitely extend to UK academics? They mention a .edu address is required, and I didn't hear back after applying with a .ac.uk address.
If you're based in the UK and interested in research software, you might want to look into 'The UK Community of Research Software Engineers'[1] and The Software Sustainability Institute[2]. From what I've seen, the latter in particular are exploring pragmatic ways to make software engineering more compatible with the expectations (e.g. citations) of academic employers.

I'm looking at something similar at the moment, but in agricultural areas where line-of-sight is inhibited only by foliage and terrain. For my purpose, it's OK to collect an SD card every so often, but I've toyed with the idea of an ESP8266 and a directional antenna to e.g. a mobile broadband router, probably again with an antenna upgrade.
Earlier today, I found [1] which - amongst other things which you might be interested in - calls out a venture [2] to establish a network of 'citizen scientist' type flood sensors across the UK. Their scheme looks to be a network of radio-to-Internet gateways which support a number of independently-deployed sensor nodes.

> I hope the published version in 2008 had it
The published version has headings: Latitude, Latin name, Modern name and date of Roman foundation, Axis, Amplitude at solstice, Published research. Still no map, though.
Constraints on template types are useful outside of metaprogramming proper. For example, the standard library already specifies classes of iterators dependent on e.g. the direction(s) in which they may be advanced.
n.b. it's a double-pointer. The /called/ code probably allocates a dns_name_t itself, updating the /callee's/ pointer. If the callee's pointer isn't NULL, there's a chance overwriting it will cause a memory leak (as the caller may no longer have a reference to whatever it was pointing to). The comment acknowledges that it's perhaps unnecessarily strict.
I got a free copy of the lot back around 2003, but when I looked recently they've officially switched to printing on demand (priced at ~cost) via Lulu. I first got them for hobbyist operating system development - their residual utility there should remain high for a while. Plus, bookshelf cred!

From the paper[1], it sounds like the same linear motion with the film wrapping around to the top:
> The sphere is dipped with

> northern hemisphere is within 2mm. However, near its south pole
> the error is much larger (about 5mm). This is because after the
> water surface passes the sphere’s equator, the film gets stretched
> largely, and near the south pole the relative angle between the
> water surface and the object surface approaches to 180◦, leading
> to an ill-posed boundary condition for our simulation (recall
> Equation (1), when θ ≈ 180◦).
You can see the potential for a similar wraparound even on e.g. the mask dips.

You might find (Typed) Racket interesting - it offers the features you mention, and is a delight to work with.
I have this kicking around from some experiments a month or two ago:
sudo apt-get update
sudo apt-get install build-essential linux-image-extra-virtual
sudo reboot
echo options nouveau modeset=0 | sudo tee -a /etc/modprobe.d/nouveau-kms.conf
cat > /etc/modprobe.d/blacklist-nouveau.conf
blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off
<Ctrl+D>
sudo update-initramfs -u
sudo reboot
sudo apt-get install linux-headers-$(uname -r)
wget http://uk.download.nvidia.com/XFree86/Linux-x86_64/346.35/NVIDIA-Linux-x86_64-346.35.run
chmod +x NVIDIA-Linux-x86_64-346.35.run
sudo ./NVIDIA-Linux-x86_64-346.35.run
nvidia-smi -q | less
This is obviously not production-ready, and is heavily cribbed from online (I couldn't quickly re-find where) but is good enough if you just want to play.
EDIT: I think this was the original: http://ubuntuhandbook.org/index.php/2015/01/install-nvidia-3...
You're right, sorry. I responded to 'why round?' but missed that comment.
The clue's here:
> What is the `uniform' distribution we want, anyway? It is obviously not the uniform discrete distribution on the finite set of floating-point numbers in [0, 1] -- that would be silly. For our `uniform' distribution, we would like to imagine[*] drawing a real number in [0, 1] uniformly at random, and then choosing the nearest floating-point number to it.
Because of the logarithmic representation, there are as many floating point numbers between .25 and .5 as there are between .5 and 1. If you uniformly sample numbers with an exact, finite floating point representation then you don't get something that 'looks like' a uniform distribution of real numbers in [0, 1] -- which is more likely what was wanted.
No, the standard requires they appear in their order of declaration.
Relatedly, 'The Box: How the Shipping Container Made the World Smaller and the World Economy Bigger' is a great little book. I don't see sense in retreading existing reviews, but I think it would offer something of interest for many in this crowd.

From the icons, it looks like this may be using Geogebra[1] under the hood. It's a really polished little tool for exploring geometry.

Try sketching the call graph of e.g. fibonacci 5.

I'm curious - it seems a little around-the-houses to have to use an approximation to erf when it's not obviously relevant. Why not just use an alternative sigmoid (e.g. the logistic function) or whatever the trigonometric solution falls out to be if you model it as a 'real' slewing or rotation motion around the scene?
Looks like: IPv6 addresses for NS (nameserver) and MX (mail exchange) records, and root and www subdomain. Looks to check DNS responds to queries over IPv6, too. Easy mode to get at least four stars: enable IPv6 with a free Cloudflare account.
I used it to take a contact database for a series of seminars around the country and allocate participants to the geographically-appropriate venue.

300,000,000 / 7,000,000,000 = 3 / 70, or a little less than half (3.5 / 70) of 10% (7 / 70). About 4%.
