Joe Vávra’s Perm Walk

On this very interesting article, Joe Vávra gives his opinion on a very peculiar walk taken by a security researcher, which he and other security researchers have found to be quite interesting. I would like to address an important topic that was not addressed by Joe’s article, and that is the notion of a ‘perm walk’ as Joe uses the term.
“The walk consists of two phases : walker moves from one cell to another, and the walker must remain within the limits of the area defined by the two cells until complete.
Here is what I think Joe is missing: A walker‘s movement is not defined by the two cells that it occupies. Joe’s walker never leaves a cell. It is still there when he leaves it, so that he is unable to move into two adjacent cells. Joe can’t even move, say, into the first cell (i. the cell containing the ‘b’ in ‘barracks’), because the walker is located in the ‘b’ cell. So there is no possibility, let alone probability, that Joe’s walker can move into a cell that his walker does not occupy.
A perm walk also cannot be described purely by the movement of the walker, because ‘perm’ can be used to mean ‘change to the direction of the arrow’. If Joe takes the walker to the right, but the walker stays where it was when Joe took him to the right, ‘perm’ does not involve ‘moved’ the walker in the same direction. That is why no perm walk can be described using this term alone.
What Joe has described is a perm walk, and no other perm walk! Joe’s walker’s movement moves in a different manner than a walker’s movement, but it is still a perm walk because it is still defined by the two cells that the walker is located in.
Joe O’Connor and the Twitter compromise – Plugwalk –
Joe O’Connor’s proposal to the European Commission (EC) to break off relations with Twitter was met with a degree of uncertainty by the US State Department (DoD) on 9th June, 2016. With an ongoing, well-orchestrated, global campaign to discredit, ridicule and damage the Twitter-based movement of civil rights activists and journalists, the DoD has been in no mood to support a Twitter boycott or Twitter’s stance as a platform for criticism of Israel. This is precisely why the DoD has been engaged in a sustained campaign of cyber warfare, including attempts to undermine the Twitter account of the Jewish Voice for Peace (JVP) – a Twitter account that is widely known to serve as the primary advocacy and information point of view for the JVP’s activities. The DoD has been working on this issue for over a year, but the attacks and counter-attacks on JVP have not yet borne fruit.
This event is the first in a series of articles, hosted by the S3-POD, that provide a historical view of the developments leading up to, and following, the establishment of the State of Israel (SOI). It examines the background to the decision to create the State of Israel, from the political process, to the finalization of the Declaration of Independence, to its ratification by the Congress of the United States, and the formal establishment of the State of Israel. It then focuses on the diplomatic and diplomatic developments of the period following the United States’ recognition of the State of Israel, from the formation of the United Nations to the establishment of the State of Israel. Finally, it briefly discusses Israeli Foreign Minister Avigdor Liberman’s visit to Washington in November 2014, and concludes with his view on the impact of the State of Israel on the Jewish people and on the wider Jewish diaspora community.

An indictment against Plugwalk Joe Clark in the Twitter – Bitcoin Scam.
The Computer Software Industry is at war with the Bitcoin community. It is the latest step in a campaign of intimidation and legal harassment designed to control our free speech! — Joe Clark, COO of Plugwalk Joe Clark | Plugwalk, Inc. – A bitcoin startup that’s built over the last couple of years, Plugwalk is an Internet search engine that’s designed to help people find information and solutions to problems they encounter online. Plugwalk’s mission is to provide the tools for people to be their own computers. This is the way we build “a better world” and the way all people can be their own computers.
This indictment against a new member of the Bitcoin community and online activist, is an extreme abuse of Computer software industry power and tactics.
A new company named Plugwalk is trying to disrupt the Bitcoin community with the message that using computers to solve problems is “not cool”. Plugwalk has a website, a Twitter account and a blog. They claim to offer bitcoin-mining and Bitcoin software solutions built from the ground up from the community that will be distributed for free to the public. The idea is to make the internet accessible to everyone who wants to spend time in what they consider their “own backyard”.
Since the beginning of the year the Plugwalk website has had quite a number of users, with many signing up for and using tools that will allow them to run their PC’s on a free virtual machine created and maintained by Plugwalk.
The Plugwalk website boasts about how they’re creating “the world’s most secure Bitcoin mining pool”. They also tell a number of new users that there’s Bitcoin mining software available.
Plugwalk’s most recent blog post is entitled “The Truth About Plugwalk”.
Plugwalk states that “plugwalk is a decentralized Bitcoin mining pool that uses the Bitcoin blockchain for verification and security. It is currently the only bitcoin mining pool that can produce more than 21 million bitcoins per hour of mining.
The Plugwalk blog post continues, “plugwalk is building a completely free Bitcoin mining pool that is capable of producing over 21 million bitcoins per hour of mining.
Tips of the Day in Computer Hardware
The Xeon D CPU, SSD, and a New Gaming Mouse.
Today is Computer Hardware’s “Open Data Day” and it’s an event that runs from 2 to 7 p. As part of the event, I went out and spent some time with a few of the best systems and hardware I’ve had the privilege to play with in person. If you missed my review of the ASUS ZenFone AR, you can read that article in the link below.
We also had a quick chat with Intel, who sent us their Xeons (now more commonly known as Xeon processor E5 processors and not Xeon Ds, Xeon Phi, or the latest Haswell), as well as a gaming mice. These are the systems that I would take to the next level and use in conjunction with the latest hardware.
Intel has been on a tear lately with the arrival of their “Knights series” of chips that have the Xeon D (code-named E5-2690 v3) CPUs running on them.
