Using Memory Errors to Attack a Virtual Machine

gillus writes "A very cool scientific paper from Appel and Govindavajhala that explains how virtual machines like java or .Net can be exploited. How? Quite simple, bomb your DRAM chip with X-rays... or more simply with 50-watt spotlight, as the authors demonstrate. Definitively worth a read!"

  4. On the Linux Community.. by PanicOfTheMasses · · Score: -1, Offtopic
    I'd like to take a bit to reflect on the linux community and where it's come out of and the state of it now.

    As a user of the operating system, I find it to be largely an excellent product. And the community has been hugely successful in waging a war against Microsoft and for the brief time it's been a serious competitor to the software giant, it has indeed made huge strides.

    The product, beginning several years ago, has enjoyed excellent growth, especially in the past few years. While the pace may be slowing, it should not take away from the growth of the community in previous years.

    The state of the community, itself, is a bit more disturbing. In general, the linux community supports open source, that software usually should be free, and that intellectual property should be very much limited.

    In the battles for freedoms to distribute the DeCSS source and for MP3s, the community has gained the reputation as thieves. In this, they have taken on companies and organiations that are generally respected or at least accepted by the public. Not to say that the organizations, such as the MPAA or the RIAA, are right, but the public tends to believe them.

    It's very easy to portray what the linux community does as theft of products, services, and a threat to the United States economy. As long as the community supporting linux has the reputation as thieves, it will also tend to give the product a bad name.

    I'm by no means saying the causes to fight far are wrong, but it's necessary to pick which battles to fight, and the community seems to have chosen too many to fight at once. The media can control and influence public opinion, and tends to be biased toward the rich, like it or not. In such an environment, linux is at a handicap already, and fighting the battles they do makes it that much worse.

    It tends to reveal a more disturbing, and to an extent hypocritical attitude about the linux community. The United States is based on capitalism, and what the linux community seems to support is far closer to socialism.

    The attitude is to support big government against big business, but that same big government should not touch the people. I can't see how this is possible, and it's definitely asking far too much. You simply cannot treat a business different than a person in what rights they are entitled to and what liberties they are granted. What this is suggesting is that the government take up an ideology of what is good and what is evil, and this is simply not acceptable. This goes against anything the United States was founded on, and is a rather scary thought.

    Capitalism has worked well for the United States and while it is not a perfect system, it tries to protect the rights of all when it is regulated to some extent. You cannot choose who to regulate and who to let alone, you must instead regulate all equally for a system to be anything close to fair.

    Instead, the linux community acts like freeloaders. They want to have good products, yet they are unwilling to give any payment to those who bring the products to them. They fight the rights and liberties of those who control intellectual property, but they want their rights and liberties protected by the government.

    This is a narrow view of the world and an immature one. The linux community can't even seem to get along, and it is populated by many immature individuals. Not to say that everyone in the community possesses these attitudes and undesirable qualities, but they certainly do prevail.

    And one of the largest sites and a favorite among the linux community, Slashdot, is a hotbed for trolling and flames. A real troll is a masterpiece, it takes time to develop into what it targets to annoy. It attempts to appear as a legitimate post. A real troll is funny. Trolling is enjoyable, but what prevails on Slashdot is not real trolling but flooding with pointless comments. This reflects poorly on the immaturity when those with different views have resorted to tactics of f
