You need ability to run specific code in ring 0 (aka the kernel) and this allows you to access memory that in theory the SMM keeps hidden even from ring 0, aka itself. Unless you are in the habit of loading random shit into your kernel this has no practical use for a hacker.
Further the issue with this is that you have been able to read arbitrary memory on the system for around the last 20 fucking years if you have the privilege to read from port 0xb2 via the delights of the SMM itself. This is just grandstanding like the hacks against AMD that involved loading hacked firmware onto the system.
It's an Intel/Microsoft/Toshiba thing that originally was for being able to fiddle with things likes fans, backlights etc. on laptops. Came in around about the time of the Toshiba T1900. All this stuff is now done via ACPI though I believe deep down it's still actually accomplished via SMM. It is at least on a Tecra M5 which is the last time I looked, but this is a 12 year old laptop now, though it was ACPI based rather than APM.
You can see it in the kernel in the toshiba, thinkpad, a dell driver and possibly others. That toshiba kernel module is mine and it is the first documentation of using the SMM for controlling things outside the likes of Intel/Microsoft and Toshiba as far as I am aware. The thinkpad and other similar drivers built off the top of the knowledge I gained.
I can still remember being astounded while single stepping through fan.exe in DOS on my Satellite Pro 400CS and seeing a simple "in al,0xb2" change all sorts of registers that should simply not be changing and the fan turning on and off.
I am not going to detail what values you need to load into what registers to read the arbitrary memory because I think it's better that it's not generally known and because there is no patch.
Not sure how big a battery with a 1728MW power output and a capacity of 9.1GWh (33 TJ) is, but I suspect at least as large as Dinorwig is. The environmental impact of which is basically limited to arctic char going extinct in the feed lake. Though that might well be in part due to the fact they where mostly moved to other suitable lakes before it when live.
However Dinorwig takes 16 seconds to go from nothing to full power and that requires the turbines are being spun in air prior to opening the valves. Otherwise it takes in the order of 90s to get to full power. I would expect a battery to be sub one second.
Though a quick Wikipedia check shows that China alone has 6.6GW of pumped storage under construction. In Europe Ukraine is building 2.2GW of pumped storage.
Batteries have a place for short term grid stability or places where pumped storage is not viable. However for Europe and North America at least pumped storage is probably more viable for grid stability at the ~1minute plus range than a battery pack.
Microplastics shedding from clothing during washing is an interesting issue. However this is not a plastic bag at the bottom of the Mariana Trench, or the floating plastic garbage island in the middle of the Pacific. This are directly caused by dirty filthy people disposing of rubbish by just randomly throwing it away when they no longer need it.
As regards microplastic shedding from clothes, the bulk of my clothing is natural fibres to start with. I also expect to find washing machines come with appropriate filters in the near future. Unfortunately the sort of aftermarket inline filters you can currently get don't work for me as being in europe my washing machine is in my kitchen and without a kitchen refit there is not the space to fit one in unfortunately.
Yes we do, dirty filty people who don't know what a litter bin is, let alone what recycling is. The amount of plastic that I am personally responsible for not being disposed of properly in my entire life is probably about 100g if that.
Problem is that 802.11s is pretty useless without 802.11k and 802.11r as well. Without the latter two your device is still hanging on for dear life to the weak signal of the first access point it connected to despite being on top of a different one.
From a personally perspective 802.11s is not a good idea. WiFi bandwidth is precious enough as it is. The last thing I want is more of it being wasted on wireless backhaul. String some fricking Cat5e/Cat6 to get the WiFi point up. Heck use powerline for the backhaul if you must but a pock on you if use WiFi for the backhaul.
Even today it would make a difference on the web. This page that I am typing in is according to a combination of wget and wc 1213 lines long. That is 1.2KB less if using a LF formatted HTML file over a CR/LF formatted one. Multiply that by all the CR/LF formatted files being shoved around the internet and I would imagined it comes to many TB a day.
Thing is they are only banning hybrids not capable of doing 50 miles on battery. The Prius can do 30 miles right now. The idea that in the next 22 years battery capacity will not have improved 60% is frankly ludicrous. In the last 22 years they have improved an awful lot more than that, and there a whole slew of battery technology innovations in the pipeline any one of which would provide the additional capacity required.
There is a long history in of needing to set targets to drive manufactures to innovate and sometimes even just implement existing technology.
Probably on a per host basis, like some of the other exceptions required to operate with the shitty embedded web servers in equipment that don't get updates so are still pre poodle etc. Not really ideal when you have a few hundred or maybee a few thousand.
The Pooh merchandising revenue stream is actually orders of magnitude larger than the Mouse which is pretty small as a percentage. At one point it apparently accounted for 90% of all Disney's merchandising revenues in their stores. The main thing is that the Pooh has enduring worldwide timeless appeal.
Weird, I managed to purchase a 3:2 ratio laptop last year. Spent a decade with my 4:3 1400x1050 previous laptop but the fan was going so after spending several years looking about for something with a decent screen I ended getting a Surface Book. After some initial flakiness, it runs well now with the exception of the GPU in the keyboard, but I don't actually need miss that to be honest, and I expect it will come in due course. It's not an issue with the latest Surface Book 2's mind you.
The US government absolutely gets to decided what countries a Chinese company can sell products to that contain *US* parts. If ZTE didn't like that they should not have used US parts then they would be free to export to whoever they liked, subject to other similar export restrictions.
See my other post. The 20 days plus bank holidays is actually the will of parliament. It came about from the 1997 Labour government with the largest landside victory in a generation enacting the EU Working Time directive in 1998 and then finding to their horror that the Working Time directive only gave 20 days combined. They promptly fixed that almost immediately they lost the case in the ECJ by issuing a Statutory Instrument 2007 No. 2079 The Working Time (Amendment) Regulations 2007 which was approved by both the Commons and the Lords. I can't be bothered however to look up the actual vote.
Note under UK and probably EU law you become entitled to your full annual leave on your first day of employment.
The chances of this changing anytime soon even after Brexit is somewhere around Ä
What happened is that when the Labour government implemented the EU Working Time directive they expected it to be 20 days plus Bank Holidays. Some employers took that to court claiming that as written the EU Working Time directive was 20 days including Bank Holidays.
This went all the way to ECJ and the employers won. The government simply went back and changed the law to 28 days. The mind boggles at the what the employers thought they where going to achieve.
I can't imagine that any government would try and change that now even with Brexit. It would be political suicide to try and take holiday away from millions of people.
Personally I get 31 days PLUS the eight days bank holidays. On top of that I seem to get an extra day most years for some milestone or other achieved by one department or another. However you are right any decent employer will offer something over and above the legal minimum.
My view and practice with any flat pack furniture is to vary from the instructions and apply an appropriate glue on *ANY* surfaces that are in permanent contact.
Assembly time is significantly longer and it needs to be left to dry before use. However the resultant product is vastly more ridged and robust, and consequently lasts much longer.
That said tolerances in CNC machined particle board should be pretty dam good. They always have been in my experience. Of course poor assembly can lead to the belief that things are out of alignment when in fact they are not.
Basically a Falcon 9 first stage is a large grid fin stabilized precision bomb with landing legs. In effect the military paid for development of the technology that allows the Falcon 9 to hit the land zones pretty much spot on every time. They where originally a Soviet invention.
The actual problem is that a large percentage of the skilled workers in these eastern european countries are now living and working in western europe. Perhaps if the respective governments had listened that said emigration was causing problems in the UK, and agreed to some limits then Brexit would not have happened.
For me the pilot new the turbulence was coming, everyone was warned, the stewardess came round and checked everything, and then during the descent for landing it hit, there was going to be no flying around it:-)
That said it was a truly eye opening experience. I won't say it was scary because I had confidence that the plane could handle it. However I now always keep my seatbelt done up all the time. I am quite sure that everyone on that flight does the same too. As would anyone who has experienced bad turbulence. If you are not strapped down you will be tossed around the cabin like a rag doll.
When you have been on a flight with *REAL* turbulence; the type where if you are not seated and wearing a belt you are going to be smashed like a rag doll off the ceiling and couple of seconds later the floor of the plane you wear your seat belt on a plane for every second it is possible to do so.
Perhaps living in europe where wearing seat belts are compulsory by law in a car we are more used to wearing restraining belts for long periods of time.
Regardless not wearing a seat belt while seated on a plane is a pointless risk to take in my view.
Not really the CFM56 engine in question has a history of fan blade failures. It was instrumental in the Kegworth air disaster in 1989 that after a couple more fan blade failures lead to a redesign and over 1800 CFM56's having them replaced.
There was another uncontained fan blade failure on a CFM56 on Southwest Airlines Flight 3472 in August 2016 before yesterday's incident that was another uncontained engine failure and I will lay a large sum of money that it was a fan blade failure of a CFM56 engine.
I would say that five fan blade failures on an engine is very unusual.
This is not counting the numerous fuel flow problems and flame outs due to rain/hail ingestion this engine has suffered.
I am going to assume that you are in the UK from the language used. You are flat out wrong, a motorway is the safest type of road to drive on in the UK. That is there are fewer fatalities per passenger mile than any other type of public road.
The issues is that when it goes wrong it can go horribly wrong much more so than elsewhere, which changes peoples perceptions of where the real risks are. Accidents only tend to make the news if they are multicar pile ups on a motorway these days.

That is clearly a forestry plantation and not natural. Its entire purpose in life is to be cut down for timber.

Nope the extra 20 years where notionally to allow authors to get the revenues that they missed out on due to two world wars.
The real reason was the German state wished to retain copyright on "Mein Kampf" so they could keep it banned.
It is hard to imagine that anyone could muster legislative support these days to extend copyright further.
