Massive solar flare sparks solar storm; possible threat to power grid, computers

    Disruptions to power grids, satellite navigation systems and computer systems feared

    By Michael Smith (Veshengro)

    On June 7, 2011 the US Space Administration (NASA) registered the strongest solar storm since 2006 and it is feared that it could affect systems on Earth.

    The most benign effect assumed will be increases aurora activities, that is to say it should be possible to witness awesome polar lights.

    Other effects, on the other hand, which would be far from benign, could be damage to satellites, interruptions and other problems by the transmission of satellite communication and data, such as GPS, because of an increased mass of electrons in the ionosphere. Disruptions to power- and communications networks through induction are also possible.

    While this event was bad enough, so to speak, space-weather experts are concerned about future solar events.

    The sun's 11-year cycle of activity, driven by tangled surface magnetic fields, will hit its maximum in late 2013 or early 2014. Magnetic messiness will peak around that time and prompt nasty solar storms.

    We will, however, probably see [extreme] flares every couple of months instead of years and if one of these powerful flares – and its coronal mass ejection – faces Earth, the particles will pound satellite components with charged particles, short some out, and potentially cripple them.

    On the planet's surface, extra currents of solar particles drive extra electric current through power lines and heat them up. A solar storm in 1859, for example, caused telegraph lines to burst into flames. Power companies distribute loads to avoid such a disaster, but energetic solar storms could still blow transformers and lead to power outages, especially during heat waves like the one sweeping the eastern U.S. this week.

    "Despite great countermeasures, the power grid is still vulnerable and we could be in for some serious problems, and not just, as if this were not bad enough, as regards the power grid. Communications, which today more often than not rely on satellites also could be severely crippled and impossible for days, if not longer.

    This also could seriously effect and impact on aviation and maritime traffic as all communications, nowadays, are dependent on satellites, as does the navigational systems of aircraft and ships.

    Yet another proof, if any more proof would be needed, that we have become too reliant and dependent on vulnerable high-tech equipment which could be put out of action by electromagnetic pulse and fields.

    Individual computer centers could be secured by use of a Faraday cage and the same could, probably, be achieved for the PC at home, but the problem is that the Internet, the system of communication that we have become so dependent upon, and that includes me, as I am no Luddite, can and will suffer under such “attacks.”

    So far, as time of writing, several days after the event on the sun, nothing awful seems to have happened so far but, as some scientists stated, it could be several days before the impact could be felt with all power.

    This may, on the other hand, just be a “shot across the bow” and should be used as a wakeup call to harden our critical infrastructure systems and the Net is part of that critical infrastructure.

Microsoft about to hand source-code of Skype to Russian secret service?

    By Michael Smith (Veshengro)

    The Russian daily Vedomosti and the British press agency Bloomberg announced the possible cooperation of the now Microsoft-owned business, Skype, with the Russian secret service, the FSB.

    It is the aim, apparently, to hand over to the FSB part of the source-code for the application and by doing so they would hand the successor to the KGB a very powerful tool to intercept Skype communications.

    Microsoft is, however, denying that this would be the case. They would, wouldn't they.

    So far the Voice-Over-IP-service Skype is being considered as extremely secure. It is impossible for outsiders, due to complicated algorithms, to log themselves into chats or telephone conversation and thus monitor communications.

    Even governments and their agencies, including secret services, do not have, according to official sources, the possibility to decode the data that is being sent via Skype, whichever form this data may be having. Skype has, so far, got the reputation that its encryption is of the highest military grade making it impossible to wiretap the conversations.

    But, if the report by the news agency Bloomberg is anything to go by then this could change soon.

    Ever since the acquisition of the Skype service by Microsoft the directors of company in Redmond have become very happy to cooperate with law enforcement agencies and intelligence services. That is why Skype is intending, so Bloomberg, to hand over pats of the source-code to the FSB.

    It was rather obvious that, as soon as MS was getting their mitts on Skype they were going to screw up the privacy that Skype used to provide. MS, like Mark Zuckerberg of Facebook, do not know what privacy means. Or would MS otherwise deem it to be right to snoop on your and my PC when we connect to their sites for updates and such?

    Should this indeed happen as indicated by the Bloomberg report then the successor organization to the KGB might not directly be given the “master key” with which to be able to tap in to each and every Skype call or chat but with the source-code they could find back doors with which to do just that.

    Redmond, however, claims that there is nothing true on the reports but they would deny such things, would they not. People would be leaving the Skype service in droves, I am sure, should that those shenanigans by Microsoft become reality and, obviously, they don't want to spook the horses as yet.

    In a statement to the Blomberg agency Microsoft reiterated that there are no moves afoot to give away the source-code for Skype but, then again, no one was talking about giving the source-code away to all and sundries now.

    According to the Russian daily Vedomosti has the FSB been developing good relations to and with many software giants and Skype would not be the first program which the agency would be given full access to.

    Maybe this will have to also be seen in the light of some recent communications that came out of Russia where it stated that the Russian government was going to switch over to Open Source altogether including Linux and such operating systems. Is Microsoft oiling the wheels so it can keep in with the Russian government?

The desktop PC is not dead

    Not by a long shot and neither should it be...

    By Michael Smith (Veshengro)

    computer_web-withtext The death of the desktop PC was rather prematurely announced and as far as I can see it might be the laptop that will lose out to netbook and smart phone rather than the desktop PC.

    The desktop is easier to assemble and far easier to repair or upgrade and hence is superior to the laptop, though not, maybe, in terms of energy consumption. That could, however, also be solved by changing the type of power supply. On the other hand, the desktop, because of its ease in repair and upgrade, will outlast a laptop and netbook and therefore its environmental footprint, even with the slightly higher energy consumption is smaller than that of the laptop.

    There are also desktop PCs about that are very good with energy and which are also nice and compact, such as and especially the “Broadleaf” PC from VeryPC, and UK company with the PCs being made in Britain. The entire PC, with the exception of the screen, is no larger than what was an external hard drive or DVD drive some years back and takes up very little space indeed.

    Then there is/was also the Cherry Pal PC, though it would appear not much has been heard of this one for a while now, though, according to their website they still seem to be in existence. When it comes to the specs, however, it would appear that the Broadleaf PC from VeryPC is superior, as it has a proper internal hard drive of 250GB rather than just a 16GB flash memory.

    The old larger machines, while, maybe, as said, not all that energy efficient, and that is due to the power supply, which all too often is far to big, in more than one sense of the word, still have much to offer too in way of sustainability than other computers. The latter simply because of the fact that they can be easily repaired and upgraded and that because of the way they are constructed and the fact that they are in a large (metal) case.

    I am at a loss, to be perfectly honest, why people wish to declare the desktop PC for dead and try to get consumers and businesses onto laptops and netbooks and the cloud. If I would be so inclined I would, maybe, begin to read a lot more into this and one, possibly, should ask the “Quo bono?” question here.

    One of the biggest problems with power consumption in a computer is bloated software, from operating systems to the rest. Microsoft Windows is getting bigger and bigger and, Windows also has the nasty habit of permamanetly doing something in the background. Even when the PC is not, actually, processing information the hard drive is spinning most of the time, which is noticeable from the HDD light being on. Not something that happens with, for instance, Linux operating systems.

    Linus Ubuntu, even in its latest reincarnations, still comes on a CD (700MB) with all the additional software you may wish for, even for small business use, while MS Windows takes up several DVDs by now at 4GB each. It is therefore no wonder that old PCs are “obsolete”, as far as Windows OS is concerned, within a couple of years. No such problem with Open Source Operating Systems and general Open Source software.

    An old(er) desktop PC, with Linux, can still outrun a dual-core laptop with Windows Vista or Windows 7 in startup time and general operations and thus we, who wish to keep things out of the waste stream should very much consider hanging on to those machines and improving them with the right software and the right hardware upgrades, where possible and affordable.
