Comment Just the easy bit (Score 3, Interesting) 55

As an IVF father, I have seen the end-to-end process, and this is just the easy bit. Over-stimulating egg release and harvesting them comes first, which is where the bulk of the cost comes from (the necessary drugs followed by surgery), and then there is embryo nurture and monitoring for a few days followed by implanting back in the mother afterwards. The direct injection of sperm into egg (ICSI = intracytoplasmic sperm injection) is not even used in many cases, except where for some reason the egg will not fertilise from outside contact. This robot saves less than an hours work for the person with probably the lowest salary on the team other than the receptionist.
As for "Think of a box where sperm and eggs go in, and an embryo comes out five days later," the same problem applies as with existing IVF: getting the eggs.
I'm not knocking this as a technological advancement in micro-manipulation, but advances in increasing the success likelihood of the first and last stages would be preferred by most IVF 'customers'. It is an expensive process which is more likely to fail than not.

You just need the right imagination. Try being adaptible. If you thing the hex is the fifth, what are the others?

The braille was so obvious I did not consider it might be the first layer. I thought the colour of the characters in the two rings was the 4th layer. I have decoded one of them, but not the other. One of them has two colours, and can be interpreted as binary to give a 10 character message, 8 of which are obvious in meaning, but the middle two are odd. Might be a clue to the outer ring colour problem, which is three colours if you look carefully, including on the two dots.

That makes:
Layer 1 = braille = single word clue to layer 2
Layer 2 = Outer ring of letters (DVX...) = message and clue to layer 3
Layer 3 = Inner rung of letters (BGO...) = message and clue to layer 4
Layer 4 = Hex (join each row together to give a single string) = message
Layer 5 = Colour pattern in rings. Inner ring = short message. Outer ring = ???

Comment Re:lego bricks (Score 1) 204

My son (just turned 5) never really liked megabloks, duplo or any of the bigger 'block' construction toys, but loves standard Lego. He has quite a few Lego City sets, so generally vehicles, and a large bag of ebay sourced 'mixed bricks'. Nothing from any commercial tie-in theme, which he wouldn't recognize anyway. He is capable, when in the mood and not too tired, of following even quite long instruction books through, although it is a rare construction that does not then get heavily modified afterwards.
If he is particularly lucky he gets to play with 'Daddy Lego'. My old technic sets, some of which are approaching 40 years old.

Do not encourage solar observing at a young age. Wait until they are old enough that you can trust them to carefully inspect the filter for damage and check it is properly in place before EVERY time they use it. Besides which, cheap filters will only let you safely see a silhouette of the sun, so are good for transits or eclipses, but that is about all. If you want to see proper solar activity you need a narrow bandwidth filter for the hydrogen alpha (other wavelengths are available) wavelength, and they are very expensive.

Comment Surge protectors may not protect (Score 1) 236

All my kit used to be connected to surge protectors, but having had the main trip switch go a number of times I got a professional electrician in. He commented that surge protectors and RCD units (not old fashioned fuse-wire) in the main distributor box can interact to cause slight earth leakage, leading to the trip. Sure enough, changing the surge protectors back to standard 4/6/8-ways stopped the frequent failures.
In addition, and this is UK specific and may not apply in the US, the way the national grid is designed prevents the sort of high spike on the live connector that a surge protector is meant to block. In the unlucky case of a _very_ close lightning strike to the ground there will be a surge, but it will come through the earth wire, not the live, which the surge protector cannot stop. Phone line spike protection can still be a good idea though.

Yes, CO2 does increase the heat capacity of the atmosphere. Yes, industrial processes release CO2.
HOWEVER, if that was all there was to it, the global temperature increase would pretty small. (Probably measurable over a long enough period, but not enough to have a serious impact.) It is the supposed secondary effects that are claimed to produce the large changes. e.g. A slight increase in temperature increases the water evaporation rate faster than it increases the rainfall rate, so leads to an increase in cloud cover, and clouds trap heat, so the temperature goes up further. To model this sort of thing accurately you need a very good model, otherwise you get answers that are probably wrong, although also possibly just what your assumptions lead you to think it should. Early climate models did not even include clouds, and the above chain reaction was used outside the model as an 'obvious' argument for global warming. I have not looked at the current state of models for some time, but even after some started to incorporate cloud modelling they still did not include atmospheric dust. Higher temperatures lead to more ground dust, which is picked up by the wind and becomes nucleation centres for rain drops to form on, reducing the cloud cover again, counteracting the above change.
Why do you think that the models have not predicted the pause in the temperature rise for most of the last two decades, where explanations such as deep ocean heat absorption are now been suggested? It is because the models are incomplete, and so provide forecasts that may sometimes coincide with reality and sometimes diverge.
My background is as a physicist, and I used to produce computer models. Just simple ones of a dozen electrons, but changing a few parameters slightly could lead to large changes of behaviour. When somebody says that drastic action needs to be taken I need more assurance than 'The computer model says so.'

Oh dear, oh dear, oh dear. From the article:
For example, parents may not be aware that network-level blocking systems are unable to selectively filter ‘encrypted’ traffic. ‘Https’ encryption is a way to make traffic unreadable by intermediaries such as ISPs. It is widely used in online financial transactions, for example. It is also increasingly common in routine, everyday Internet use. New browsers are built to check if encryption is available, and if so, to use it. Encryption makes it impossible for an ISP to ‘check’ the web address the user is visiting.
For example, recently BT was ordered by a court to block customers’ access to ‘Newzbin2’. But that does not prevent people from visiting ‘https://www.newzbin.com’.

Somebody doesn't understand the difference between an address and a protocol.

Officials Sue Couple Who Removed Their Lawn 819

Hugh Pickens writes "The LA Times reports that Orange County officials are locked in a legal battle with a couple accused of violating city ordinances for replacing the grass on their lawn with wood chips and drought-tolerant plants, reducing their water usage from 299,221 gallons in 2007 to 58,348 gallons in 2009. The dispute began two years ago, when Quan and Angelina Ha tore out the grass in their front yard. In drought-plagued Southern California, the couple said, the lush grass had been soaking up tens of thousands of gallons of water — and hundreds of dollars — each year. 'We've got a newborn, so we want to start worrying about her future,' said Quan Ha, an information technology manager for Kelley Blue Book. But city officials told the Has they were violating several city laws that require that 40% of residential yards to be landscaped predominantly with live plants. Last summer, the couple tried to appease the city by building a fence around the yard and planting drought-tolerant greenery — lavender, rosemary, horsetail, and pittosporum, among others. But according to the city, their landscaping still did not comply with city standards. At the end of January, the Has received a letter saying they had been charged with a misdemeanor violation and must appear in court. The couple could face a maximum penalty of six months in jail and a $1,000 fine for their grass-free, eco-friendly landscaping scheme. 'It's just funny that we pay our taxes to the city and the city is now prosecuting us with our own money,' says Quan Ha."

Ubisoft's Constant Net Connection DRM Confirmed 631

A few weeks ago we discussed news of Ubisoft's DRM plans for future games, which reportedly went so far as to require a constant net connection, terminating your game if you get disconnected for any reason. Well, it's here; upon playing review copies of the PC version of Assassin's Creed 2 and Settlers VII, PCGamer found the DRM just as annoying as you might expect. Quoting: "If you get disconnected while playing, you're booted out of the game. All your progress since the last checkpoint or savegame is lost, and your only options are to quit to Windows or wait until you're reconnected. The game first starts the Ubisoft Game Launcher, which checks for updates. If you try to launch the game when you're not online, you hit an error message right away. So I tried a different test: start the game while online, play a little, then unplug my net cable. This is the same as what happens if your net connection drops momentarily, your router is rebooted, or the game loses its connection to Ubisoft's 'Master servers.' The game stopped, and I was dumped back to a menu screen — all my progress since it last autosaved was lost."
