You're kidding right? I can honestly say it has never found anything for me when I've tried it (Windows 7). It is dog-slow and the results are always irrelevant.

Debian Wheezy user here. I stuck with Gnome 3 for almost a week ("give it time, you'll learn to love it" they say). I now use XFCE and like it. What is it with the Gnome guys? Why do they think it makes sense to build something so unusable, and then tell us users that we're the problem, we need to "change our workflow"? I expect Windows to treat me like an idiot, I don't expect the same from the open-source world. Congratulations Gnome, you're exactly as crap as Unity.

Really? I have an LX3 and it is excellent in low light. I have a photo showing the Milky Way somewhere that is a bit noisy - but it was taken by pointing the camera straight at the sky - no telescope!

This is excellent advice. Buying a camera is easy and difficult for the same reason: they all work pretty well. For most of us, the difference between a cheap point-and-shoot and a fancy DSLR is actually rather small. The highest value is in having the camera with you, so it should be small and light. I used to use a bulky SLR in the days of film (a big brass Russian Zenit). It was fun and swapping lenses and filters around for different effects interesting. Now I have a compact digital with one lens (with zoom), and I take more photos. If you want to leave some room to experiment with the technical stuff, get a camera with a good manual mode, so you can set the aperture, shutter speed, etc. But honestly, I use these for maybe one or two in every hundred photos. I enjoy letting the camera figure out those settings, so I can spend my effort in composing the shot. I have a Lumix LX3 and love it, but there are many other good cameras out there. But as the parent says, make sure you hold a camera before buying it. Lots of menus are bad - you need to be able to find those buttons without even looking. And whatever you buy, practice with it lots.

The faculty hiring process (at least here in Europe) really doesn't care what subject is listed on your certificate, as long as you have the right experience. The title of your thesis is much more important. In fact, people who cross subject boundaries often earn a little extra respect - it helps you to bring new ideas from one field to another. My prof is famous for his work in biochemistry, but his degrees are all in physics. It hasn't hurt him at all. I do not know if this works outside of universities though, where there is likely to be less understanding of the details of your PhD. The hurdle, as ever, is to get past HR so you can speak to someone who actually knows something about the job you've applied for. Sadly, I suspect HR will dismiss anybody who has a PhD in anything other than stats, if that is the job title. I'm not sure CS has any advantage over biology in this case though.

Steve Smith has been doing this at the John Radcliffe in Oxford for maybe ten years or more. He's a maxillofacial surgeon, working on difficult facial reconstruction (seriously, these guys get to see some ugly messes - what they do is incredible). He has a 5-axis mill, and some software cobbled together by a former PhD student. He uses CT data to cut out skulls from foam, so he can practice fitting plates to the skull before opening the patient. They also make neat desk ornaments.

Erm, great summary. A link to some university rag, but none to the original article.

The idea of a university has survived since medieval times. The surrounding world has changed significantly, but the model still works. The idea that old==bad is largely a marketing one.

Information is not free. Those universities have large, well-stocked libraries, and professors to point you to the right section. Those books are expensive, especially when you're not even sure which ones you need yet. There is a ton of information online, some of it even accurate. But you need to know quite a lot to be able to judge whether you are reading something correct, deliberately misleading, or just plain wrong. For the details, most of us still use books.

A society where one needs a college degree to achieve financial security is clearly broken. We all place too much emphasis on degrees. Academic degrees are very good for a very small proportion of jobs. If we can get over the idea that academic qualifications somehow make a person superior, the world will be a better place. To quote an old example, when your kitchen is flooding, you don't need an expert in fluid mechanics - a plumber will be much more welcome. Why is this important? Because when we send less people to university, we as a society can cover more of the cost. This is only unfair if you think everybody needs a degree. At the same time, a decent apprentice scheme is also very beneficial to society (see Germany for a good example).

Well, I don't like ribbons, but I'm not afraid of change. It wasn't just the ribbons, but they certainly helped. I finally changed my work PC to Linux.

Lots of you have commented that Kindles just don't have a big enough screen for scientific papers as PDF. When I look at the papers I have next to me, they're all formatted as two columns (so your eyes don't lose track of the line you're reading). So what we really need are scientific papers formatted for e-reader. Are any of the major publishers doing this? (Yes, I know we all have a ton of PDFs, but let's look to the future for a moment...)

A lot of scientific software is run less than 10 times, often only once. It generates the result, end of story (well, go away and understand what you got). There really is no point in extensively recoding for reuse, checking all the consts are const, etc. Documentation of the form 'does X using method Y (numerical recipes page P)' is often enough - i.e. a couple of lines of comments at the top of the file. It doesn't have to look nice, it just has to be correct. And don't even get me started on optimization (spending three weeks to cut a 12 hour runtime in half is not worth the effort).

How about charging $8 for the first person who accesses the paper, and then putting up free for everyone else?

There is a better way. Various groups are seriously trying to push open-access publishing, Frontiers being one example (frontiersin.org). When you look into the problem a little more closely, you find that publishing isn't free. Hosting the PDF is cheap, but somebody has to produce it in the first place and maintain a website. And before that, someone has to arrange for the peer-review to happen, find an editorial board and reviewers, etc. Most open-access outfits use the publisher-pays model - i.e. you pay to have your article published, and then anyone can download it for free. The trouble is this shifts the payments from the largely invisible library subscriptions (taken from university staff overheads) to a very direct, comes-off-your-grant payment. But it is still a better model - we just need to see publishing become a recognised cost in grants. Your article is then, subject to peer review, freely available to anyone who wants it - an the authors retain copyright. Think about it next time you're publishing.

Now, does anyone want to explain why impact factors are a crap, self-serving metric that promotes more rather than better articles?

...nobody has yet found a PC capable of running Windows 7 today.

(I upgraded from XP last month. I upgraded the PC at the same time, to what sounded like quite a fast machine. But Win7 destroyed that advantage. How I wish I didn't need proprietary packages - then I'd switch everything to Linux and shout less at my computer)
