Comment Production takes energ (Score 1) 275

It as always been understood that producing green energy products takes energy and that has to come from the existing power grid, which in almost every country involves CO2 production. If you look at solar companies roofs in china they have panels up and companies like JA Solar are net zero. But their individual net zero status is irrelevant to the planet, the power demand is the same. We deploy all the solar we make, it's the fastest growing power source in the world and in China. They consume more than half of their own panels for their own grid. Solar is also the cheapest power source and that is why it is so poplar.

The time to stop was the early 1980s when we were sure it was happening and knew what the result was going to be. It was definitely urgent by the early 2000s after Kyoto had failed. Now its all over but for the dying we have already emitted enough to end our species, there is just a lag before the planet heats up and all the last tipping point is breached.

Comment Multiple problems combining (Score 5, Informative) 76

There is a few problems combining to cause this issue. The first is that in order to get Wind farms to be made capital owners are requiring a minimum price for a MWH to ensure their costs will be covered. That isn't unreasonable given government wants them built but one of the reasons is because the grid isn't actually available yet with sufficient capacity to take their power but government still wants the farm built. So a compensation deal is agreed. The various grid companies across the country are ridiculously slow in building out infrastructure, their backlog for projects goes into 2045 and they haven't expanded their capacity to compensate so even though the Wind farms are getting built and connected its often with lines not sufficient to take all their power at peak. The issue goes further than that because there are multiple companies and there is a lot of issues cross connecting the country. Scotland has lots of wind farms but no where near enough connection to England to pass the power down, so for large periods of time there is just excess wind in Scotland that no one can use and its the border between different grid companies so hence no ones fault. This backlog is also causing big issues with companies that want to install Solar too, they require permission from the grid and they aren't getting it. Since pricing is done across the country as a single price what often happens is sufficient power is available but it turns out it can't actually be transferred so they end up bringing the gas turbines online, the algorithm doesn't take account of the limitations of grid transfer. If it did then batteries would make a lot of sense and could be used to reduce some of the problem and store the power excess but the incentives for that are all misaligned at the moment and again battery requires the national grid companies to connect them and a lot of battery projects are stuck in that backlog. So the end result is paying for wind turbines to curtail while also paying for gas turbines, because the power can't be transferred from where its made to where its used and like all the private companies in the UK they are all about maximising profits and don't care if it brings the country to its knees doing it.

Comment A tool like Stackoverflow is needed (Score 2) 103

What Stackoverflow brings is definitely something that is needed and replaces the forums we had before well. But the balance between allowing badly formulated questions and multiple routes to an answer need to be supported better. I am not quite sure what the right solution is to this but its not putting the power to shut down questions into high reputation mods hands. Reddit posts survive despite mod power trips and I think there is a lesson in that. It may be the right way to do this is to have employed staff that check questions and point to existing solutions if they think it fits. Maybe the answer is just letting the user say an existing Q/A doesn't answer it is enough to allow the quesiton to proceed. Whatever happens Stackoverflow is a useful site ruined by policy and the community it built.

Comment the last in a long chain of evidence (Score 2) 111

While the first finding of this particular type there have been numerous studies finding neural inflammation including glial cells as well as continued infection of the brain well after the acute infection has passed. Many have been much larger and more compelling than this small study. There are about 550,000 papers on Covid harms and Long Covid now, it's one of the most studied viruses of all time and it does a wide range of damage I know of no papers saying Covid is just a cold.

Comment Re:Why (Score 5, Informative) 87

Because it improves performance by saving drive reads and writes. For example we have a program in memory and its doing nothing sat idle consuming half of all our memory. But we are using another program which is reading lots of files in and writing out updates. The second program if given more RAM for caching the file contents its reading would run considerably faster, the NVMe SSD might read at a few 1GB/s but RAM is going to be 100x faster. If the OS pushes the unused programs memory out onto the swap we can that memory for file cache and get better performance for the current program doing work. We can also cache writes into files and only push completed large groups of blocks back to the drive allowing bigger sequential writes which results in less IO overhead and sequential access. If you have ever run CrystalDisk you will know is substantially faster to do this than apparently random writing or individual blocks of 4k.

Comment Linux uses Swap even when memory isn't full (Score 5, Informative) 87

Linux uses swap even when RAM isn't full. VM_Swappiness means that it will push pages of programs memory use out if it thinks it can get more performance with the memory for file caching. More information on how this sort of works before this patch: https://www.howtogeek.com/4496...

Comment Prevention better than waiting for a cure (Score 1, Troll) 96

Ideally people are already wearing N95/FFP3/KN95 masks to avoid catching this virus due to the high chance of Long Covid and other concerning consequences like Diabetes, cancer and death. It's always circulating and prior mild infections unfortunately doesn't mean the next one won't be the one that permanently disables you. There is no cure for Long Covid, no treatments and no funding for research. Many countries don't even recognise it as a disability which is why so many with Long Covid loose the ability to work and then end up homeless. So mask up, it's the only defence that actually works because unfortunately the vaccine does not stop Long Covid from happening.

Comment Re:Not reverse: slowing down (Score 1) 104

A lot of European countries have been reducing their Carbon emissions for electricity, industry and cars for over a decade at this point. Some countries are already at the point of almost completely eliminating CO2 production on these elements such as Norway where most car sales are electric and electricity is most geothermal and hydro power. Its good to see China finally turn the tide and start reducing its impact a bit but its got a long way to go for net zero as does the USA.

Comment Re:"Guarantee" ? (Score 2) 41

This happens with every sale like this. The incoming company promises that it will keep all the employees hired and the culture wont change and all the data the company has will be handled in the same way under the terms it was collected. Then once everybody, including the regulators, has moved on they start cutting the staff and moving the operations into their existing business and then once all the prior culture is gone and all the distinction in the data is disappeared the data is now successfully embezzled and is now being sold openly. We have seen this happen so many times now, everyone knows its just a show that appears at least to comply for a few years at most.
