I've read the docs but I haven't tried it yet. I like the idea of storing n-dimensional data in an n-dimensional table, and I like the separation between the data ('cube') and the views and rules. I like that the rule

If we had a display with n (n>3) pixel colours, say (red, green, cyan, blue) for example, we could display more of the colour space. Shopping list: 4 colour channel display, 4 channel GPU, 4 channel software. Why isn't this a thin

I'd be concerned about clay heave (where clay shrinks/expands depending on moisture content, which likely varies over the year). If the posts at each end of a panel move out of plane there will be a twisting moment on the panel,

I meant lead carbonate, not lead oxide.

I am not a chemist, so take this with a pinch of salt: wouldn't lead chromate + sodium bicarbonate make lead carbonate, a white precipitate? Sodium bicarbonate is likely in your kitchen cupboard already.

Presumably from tidal forces, from the differential of the gravity field in the presence of nearby massive objects (like the sun, or jupiter).

That seems a somewhat callous disregard for the fish, blinded and swimming around with itchy eyes from burned out retina.

If the laser is powerfull enough to kill sea-lice then how does it avoid blinding the fish or giving them retina burn?

The transformer secondary was maxing out at 4A, 36V. The primary current will be much lower, probably about (40V/240V)*4A, ie about 0.67A.

This looks useful, I wish I'd found it a month ago. One suggestion: could we have a more printer-friendly version (ie, without large patches of colour and without large patches of black)?

I imagine that it would be more difficult to gain entry to an upper floor (at the top of a narrow staircase so single-file attackers) and a sturdy door with a couple of guards outside, than it would be to gain entry to rooms on the same lev

If you are a light user (in the UK) then 1p Mobile is excellent value. I've no links with them (apart from being a happy customer). They use the EE network, so coverage is good. Costs are 1p/minute calls, 1p/text message,

The magnetic drill bit rack might cause the swarf to cling to the drill bits. I use plastic picture/poster hanging grips to cover saw blades, and lengths of 4" plastic waste pipe to store dowel and metal rod.

Presumably the grocer or end user will end up with a pile of rind containing the embedded tagging chips. Fraudsters could simply gather/buy the waste rind plus trackers to embed them in their own fake products. Unless there is a robu

I had considered it briefly. Unless it is for a tiny number of residents (2?) then I think that the CQC will want to come and do inspections. It would be necessary to assume that the residents are, or will soon become, highly dependent (n

> Faraday cages are non-directional. Per-se, yes, agreed, but I was wondering whether the transmitter and receiver antenna couple into the surrounding screen differently. The degree of coupling may de-tune them differently. If so then

If the other emitter/sensor pairs are uncorrelated with our own, and if we integrate over enough transmit/receive cycles, then the other pairs will contribute approximately equally to both of our own two sensor phase detectors. T

The knowledge that we have gained from this experiment is that the experimental data disagrees with the theoretical justificiation for the idea. That isn't the same as proving that the theory is wrong, even if that seems the more lik

If you do have to kill something then at least do it humanely. Burning them to death is pretty horrible, so is zapping them with a high voltage shock.

I'm not sure it is better, unless you can do autocorrelation in hardware without using an fft. This option is unavailable on standard PCs. If done in software then a simple implementation of autocorrelation is O(n^2). An efficient im

I've just noticed an error in the above: 330Hz should read 1312Hz. The remaining figures still look ok though.
