My extensive experience as a wearer of glasses is that it is varifocals that are the hardest to live with (I am short sighted, with some astigmatism). Particularly if one is is engaged in things that require some peripheral vision (e.g. ball sport, driving, flying etc). The problem with varifocals is that they only focus straight ahead and anything to the side of that central (up/down) band is not just out of focus, but (especially looking down and sideways) distorted. This means that to look at things to the side of centre (even a little bit) requires one to turn one's whole head to move in the direction that one wants to look. Bifocals are much easier, they don't give the continuous up/down focus of varifocals, but they don't distort when looking outside of the central focused "belt", so a quick flick to the right or left just happens naturally. I am lucky, I don't need a strong prescription and only distance and reading. Middle focus (which I am using for typing this) needs no glasses at all. YMMV.

If such glasses are to become successful then they will need binocular eye tracking (and probably some kind of brain interface as well [for focusing cues]). Then the glasses' centres will also have to track each respective eyeball's focal point as well. Then (and only then) will the "automatic focusing" become useful.

Perhaps this will kick someone into looking at the database, as a whole, on a periodic basis to check other limits. Maybe do the odd test transaction or spot trends in other tables which are unexpected? Maybe run some regression tests? Then use this information to tweak the data model in controlled fashion before it breaks.

You know, like grown ups do...

You may find this manufacturer's comparison page useful.

The cost to the NHS is ~£26 each. You can buy them from registered UK online pharmacies for ~£45 each. Given that the £ has devalued rather more than somewhat against the US $, this may give you some sense of scale as to just much of a ripoff the price of $300 each is. It also makes rather a nonsense of the 8% profit margin mentioned in the article although - to be fair - it isn't made clear as to whether this is the overall margin for the company or the pens.

Assuming the UK is still the EU after 23rd June: it being being European - and according to EU rules - it too should be able to share that money. Which would be ironic, not just because it would piss off the French and the Germans, but also Newspaper (think Murdock) Big Content (er.. M..) and Cable (ah.. M) companies whom have been been lobbying the UK Government to clip the BBC's wings for the last couple of decades.

Could I gently point out that Dropbear is not, per se, a "trojaned ssh server". It is just a small opensource sshd implementation that is used for embedded applications, including things such as OpenWrt routers.

Forty five years ago, I started with some BASIC. But the thing that really got me hooked was that I had a simple problem, that mattered to me, that needed solving.

The need to solve a problem, being presented with a tool simple enough to understand and some help to get started seems to me to be the true trigger that can start someone off down the programming track.

Or alternatively: if it is not being "made" or acquired (from the Sun, nuclear tests or emissions etc) then, either way, it can be calibrated for. We know, pretty much, how much coal is being dug out of the ground and, indeed, pretty much which and volume of nucleotides that have been released. If we know this all then we can calibrate for this in the future. So what's the problem exactly?

If the returns are greater per unit time by waiting compared to the rate returned by actually spending time building and selling, why bother? Shareholders don't care about how the value of a company increases, just so long as it does.

The answer to your question is that it can probably go a lot further than you think. Where is the incentive to build more houses when, by delaying or targeting more lucrative customers, you get more money for doing no extra work? No property company nor, crucially, any home owner will buck the market by selling cheap. There are no votes for municipalities in building enough houses which could then stabilise prices - made worse (in the US) by the likelihood of them being sued by anyone that thought they would lose out.

Welcome to a small taste of the "housing boom" in South East of England. If our experience is anything to go by, you have a very long way to go yet.

People's memory is remarkably short. There is an (IIRC) official annual survey of the web (and other) servers in the USG's estate. That survey has regularly comes up with many, many poor security ratings. This is just one more example.

Yes, it's been around in server environments for years. Whilst one can see a case for adding this facility to linux servers in properly wrangled environments, my concern is on yer actual PCs, such as the one I am typing this on at the moment.
