However, using a technology called GL DSS (GSM-LTE Dynamic Spectrum Sharing) Vodafone and Huawei have shown a way to allow GSM and LTE to coexist.
In a traditional mobile network, operators allocate each technology an exclusive set of frequencies. For example, many operators, including Vodafone, currently hold 20MHz of spectrum at 1.8GHz, of which 10MHz is used for LTE and the rest for GSM traffic.
GL DSS lets Huawei's SRC (Single Radio Controller) give GSM a higher priority during periods of heavy traffic, ensuring that voice calls get though unharmed. But the SRC can also provide more room for LTE when users aren't making calls, allowing for better throughput, the vendor said on Tuesday.
There's a paper on it (or at least a similar idea) here
It's interesting because it seems like GSM will live on for low bandwidth machine to machine applications even though most of the spectrum has been converted to LTE. So if you've got an embedded system with a GSM modem, there's no need to worry that the carriers will cut off the signal in order to get more LTE bandwidth.
You presume that U.S. citizens are the only ones whose rights matter. Don't feel badâ"many of us U.S. citizens think the same way. But you will find if you talk to citizens of other countries, like Germany and Canada and France, that they also care about these issues, and care that the NSA, GCHQ and others have spied on them.
Totally dude. If only Alan Turing had done some whistle blowing on how the privacy of German U boat captains was being violated the world would be a much better place.
1200 baud is 120 characters per second. So you could dump an uncompressed 80x24 screen of text in 16 seconds. You'd just repeat the dump over and over again.
Software on a mobile phone would capture the FSK and submit it as a bug report.
Perhaps a less whimsical way to do it would be to write to a dump file and submit when the system reboots. E.g. the kernel could keep enough of the Bios alive so that it could switch back to real mode and use int 13h to write to reserved bit of the disk.
People with money can afford to be coke addicts, for a while at least. Give 'em a month or so and both sets of people will be 'borrowing' from the relatives to feed their addiction.
Or a bank of frozen ova and sperm. Or DNA sequences stored on a flash drive. Humans have 98% of their DNA in common, so you would only need to store the 2% of diffs. If properly compressed, all the genetic diversity of the entire human population of the earth would probably fit in a few terabytes.
You could save space if you only brought the DNA common in countries that developed into industrialized democracies too - Western Europe, East Asia and the North America.
He also thought that the USSR was totalitarian and not socialist. In 1945 he voted for the Labour Party which was democratic socialist. Labour was a party that grew out of the unions and whatever you can say about Labour there were definitely not about turning the workers into serfs.
Which is the point really - the USSR did the opposite of what democratic socialists like Orwell wanted and called it socialism.
If I was a member of the global elite and I knew civilisation was doomed due to my actions you can bet I'm leaving with my buddies in large, well stocked city sized Super Orion nuclear pulsejet.

Ralph Langner: Yeah, that's true. So the distribution we see with Stuxnet is mainly done via infected USB sticks. So, in technical terms, it would be not appropriate to call Stuxnet a worm because Stuxnet does not distribute by self-replication over the Internet, but thisâ"it distributes mostly by infected USB sticks. This is the exact strategy that you would use when attacking an aero jet facility. So just like a nuclear power plant. In this case, it makes most sense to assume that the attack was carried out via the Russian integrator that built the plant. Because if you are familiar with the commissioning of such big plans, you know security in those situations is practically nonexistent, especially IT security. So engineers walk in and out with their notebooks, with their programming devices that they use for programming the PLCs. And those engineers that walk in and out, they easily be lured into picking up infected USB sticks, so this makes very much sense to assume that the attack was performed via the integrator just by making sure that some of their engineers accept infected USB sticks, plug them in their notebooks, go home with their notebooks to their company headquarters, and at some point in time, go with their infected notebooks to the target site. By the way, this also explains all the infections that we see in India, Indonesia, and Pakistan. Because these are also regions where this particular integrator has business.
I've worked at companies where you were searched for removable storage going in. Hell I've worked at places where the USB ports where filled up with epoxy or disabled by group policy.
If you look at Bradley Manning air gap security is vulnerable to a single rogue employee. Also you need management that will enforce the policies - in Manning's case they should have stopped him bringing in CDs.
XP had a bug where you got very high CPU usage in SVCHOST.EXE. Somewhat surprisingly MS fixed it a couple of months ago. If I were in charge I'd have left it unfixed in order to encourage people to upgrade.
Stalinist Communism is a really bizarre piece of double think.
Before the revolution you have evil aristocrats ruling over a mass of brutalised serfs.
Post revolution you have quite a New Class/Songbun which de facto aristocracy ruling over workers working on collective farms. And workers on collective farms have no right to change jobs, so their status is much more serf-like than it was pre revolution.
Just to make it even more Orwellian the pre revolutionary system wasn't actually like this. E.g. before the Russian revolution serfdom had been abolished pretty much everywhere
Not because capitalists are humanitarians but because it's actually more efficient for rich people to employ free labourers for a wage when they're working than to own serfs or slaves.
Of course if you grow up in Stalinist state you're told that before the revolution (and in capitalist states) evil aristocrats ruled over brutalised serfs and now things are much better even though that's the opposite of the truth. And most likely you know on some level that is false - that the status of workers under 'socialism' is much close to serfs than it was either pre revolution or in evil capitalist states and even worse the ruling class is much closer to being a hereditary aristocracy.
Having been to Vietnam where the US pulled out and the Stalinists imposed their system, and South Korea and Taiwan where the US backed regimes survived and eventually liberalised I'd say she was dead wrong.
The South Koreans in particular are very lucky there wasn't an anti war movement in the US during the Korean war. If there was the South would have been annexed by the North and they'd be living under Kim Jong Un's crazy regime.
Or look at Vietnam. The boat people refugees fled the south after the war ended. So clearly a peace where they were ruled by the north was actually worse than war.
Hell as a Brit I'm very glad the WWII equivalent of the anti war movement the German American Bund didn't have as much success as its Vietnam era equivalent
The German American Bund, or German American Federation (German: Amerikadeutscher Bund; Amerikadeutscher Volksbund, AV), was an American Nazi organization established in 1936 to succeed Friends of New Germany, the new name being chosen to emphasise the group's American credentials after press criticism that the organisation was unpatriotic. The Bund was to consist only of American citizens of German descent. Its main goal was to promote a favorable view of Nazi Germany.
The parallels are pretty striking. Both the German American Bund and the Vietnam era anti war movement were openly in favour of a totalitarian movement (US anti war demonstrators carried Vietcong flags, and the AV carried swastikas) and their main aim was to allow that movement to overrun a country friendly to the US but they disguised that as being in favour of 'peace'. In Vietnam they unfortunately succeeded in that aim.
If the AV had been as successful as the Vietnam era anti war movement the US would have stayed out of WWII and the Nazis would have overrun all of Western Europe and the UK.
The other depressing thing about Nasa is how they've gone from launching people to the moon in the 1960's to telling people that driving their cars is going to kill the planet (Hansen was head of Nasa's Goddard Institute for Space Studies from 1981 to 2013). No wonder they're not keen on launching actual rockets - those things must emit loads of CO2. I'm surprised Hansen would go on exhaling CO2.
It's like something out of a dystopian science fiction novel about how a once proud, space faring society descends into ignorance and obscurantism.
In Undocumented Dos they explained that the version of Dos was a "a hacked version of MSDOS... mostly removing the file system". NTVDM runs real mode Dos programs in V86 mode. So what happens is that when when you make an int 21h call to open a file in a Dos program? You real mode code hits a BOP. A BOP is an illegal opcode. At that point the processor traps (or software emulator on a Risc machine calls out) and you end up running fairly standard user mode protected mode code which handles the file open.
In order to implement the DOS "API" (int 21, etc.) we need a way to call Win32 and kernel procedures from the VM thread. This is accomplished in Microsoft's NTVDM by writing a stub 16-bit kernel (ntdos.sys, ntio.sys,...) that hooks the same interrupts as a 16-bit DOS kernel would, but instead of actually handling these, it executes a special undefined opcode (C4 C4 followed by some more bytes indicating the desired operation) in order to trap back into kernel mode/protected mode (meaning execution will pass through KiTrap6, "INT 06: Invalid Opcode Code (#UD)"). The request is dispatched to the proper VDM and handled in protected mode, and then an iret takes execution back to the instruction after the invalid opcode sequence.
You have to admire Jane Fonda. On pretty much any issue if you look at her opinion it tells you what to do. Admittedly you should do the exact opposite of what she says, but someone that is always 100% wrong is just as useful as someone that is always 100% right.
The last of these ideas would locate a nuclear plant near a deposit of oil shale -- a type of deposit, technically known as kerogen, that has not been used to date as a source of petroleum. Heated steam from a nuclear plant, in enclosed pipes, heats the shale; the resulting oil can be pumped out by conventional means.
At first glance, that might sound like a "dirty" solution, enabling the use of more carbon-emitting fuel. But Forsberg suggests that it's quite the opposite: "When you heat it up, it decomposes into a very nice light crude oil, and natural gas, and char," he explains. The char -- the tarlike residue that needs to be refined out from heavy crude oils -- stays underground, he says.
Today, the heating of the rock is usually accomplished by burning fossil fuels, making the process less efficient. That's where the excess heat from a nuclear plant comes in: By coupling the plant's steam output with a shale-oil well, the oil can be recovered without generating extra emissions. The process also does not need regular heat input: The nuclear plant can operate at a steady rate, providing electricity to the grid when needed, and heating oil shale at times of low electricity demand. This enables the nuclear plant to replace the burning of fossil fuels in producing electricity, further reducing the release of greenhouse gas.
The world's largest oil-shale deposits are concentrated in the western United States. "We lucked out," Forsberg says. "This has the lowest carbon footprint of any source of liquid fossil fuel."
The resource that could be unlocked is enormous, he says: "Some of these deposits would yield a million barrels per acre. There's no place else on Earth like it."
Actually you could view the current extraction process as being a sort of pump priming - right now fossil fuels are used to run things. Counter intuitively it becomes more economic when fossil fuel prices are high. Now if fossil fuel prices fell you could imagine using a nuclear plant to supply the heat. Or, if fossil fuels became unavailable - e.g. due to a major war in the Middle East - you could use nuclear too. Once people have started to make money out of extracting shale oil the odds are they will use that money to stay in business.
It seems like if you could use the waste heat from a reactor to extract oil you can get even better energy efficiency than merely using the heat to generate steam to generate electricity. Also thorium means that we're not in any danger of running out of fuel for nuclear reactors.
Kirkpatrick was originally - in her words 'an AFL-CIO Democrat'. She switched sides over this issue.
Also let's look at her prediction
Moreover, the history of this century provides no grounds for expecting that radical totalitarian regimes will transform themselves. At the moment there is a far greater likelihood of progressive liberalization and democratization in the governments of Brazil, Argentina, and Chile than in the government of Cuba; in Taiwan than in the Peopleâ(TM)s Republic of China; in South Korea than in North Korea; in Zaire than in Angola; and so forth.
That turned out pretty much spot on didn't it? All the pro US authoritarian states apart from Zaire liberalised. And anti US totalitarian ones did not - not even after USSR collpased
So right now Brazil, Argentina, Chile, Taiwan and South Korea are all democracies. I've worked in Taiwan, South Korea and China and Taiwan - which Carter sold out completely - is a lot more civilised than China.
