Quantum Theory
The Theory of Quantum Fields is of great importance for gaining deeper insight into the fundamental laws of nature and has an increasing impact on novel applications. Quantum fields successfully describe the fundamental interactions in elementary particle physics and are of utmost importance for theories beyond the standard model. At the same time quantum theory plays an increasingly important role in laser-, atomic-, and molecular physics, and is an indispensable tool to study phase transitions in many-body systems.
The professors
Martin Ammon, Stephan Fritzsche, Holger Gies, Andreas Wipf
and their co-workers cover a wide range of research topics of modern quantum theory. The following table links possible research fields with lecture courses offered by members of the research group.
|Research Fields
|theory of elementary particles
|Ammon, Gies, Wipf
|gauge theories, symmetries in physics
|symmetries and phase transitions
|Ammon, Gies, Wipf
|physics of scales, lattice field theories

|string theory, AdS/CFT correspondence
|(supersymmetric) lattice field theories
|lattice field theories, physics of scales
|processes in strong electromagnetic fields
|Fritzsche, Gies
|physics of the quantum vacuum, atoms in external fields
|relativistic atomic physics
|theoretical atomic physics
Research in quantum theory and quantum field theory profits considerably from mathematical methods and the interdependency of physics and mathematics. Structural insights and rigorous results about quantum systems are often based on advanced mathematical methods taught in specialized lectures on higher analysis, geometry and Lie groups.
Theory of Gravitation
The universal gravitational force dominates on large scales. It is described very successfully by general relativity. Main research areas of the gravity group deal with strong gravitational fields of astrophysical objects like neutron stars and black holes. In many cases the application of general relativity is based on sophisticated numerical methods. In view of the burgeoning field of gravitational wave astronomy with its far reaching implications for astrophysics and cosmology, a deeper knowledge of realistic solutions of the Einstein field equations is urgently needed.
The professors
Bernd Brügmann, Reinhard Meinel
and their co-workers cover a wide range of research topics within mathematical, numerical and astrophysical aspects of gravitational theory. The following table links possible research fields with courses offered by members of the gravity group.
|Research Fields
|general relativity
|Brügmann, Meinel
|general relativity, mathematical relativity
|numerical relativity
|numerical relativity, computational physics, spectral methods
|relativistic astrophysics
|Brügmann, Meinel
|relativistic astrophysics, magnetohydrodynamics, gravitational waves
|alternative theories of gravitation and quantum gravity
|numerical relativity, AdS/CFT correspondence
Modern research in general relativity is at the interface of mathematics, numerics and new observational possibilities in astrophysics. Quantizing gravity bridges the gap to quantum field theory. The specialized courses deal with astrophysics and astronomy, mathematical and numerical methods and topics from quantum field theory.

Supreme Court Rules That Landlords Must Provide Safety To Guests Of Tenants< < Back to
The Ohio Supreme Court has found that landlords must provide a safe environment to guests of their tenants.
The unanimous decision Wednesday resolves a conflict in two lower appeals courts that reached different conclusions in similar cases.
Wednesday's decision says that state law requires landlords to do whatever is reasonably necessary to keep their properties in a "safe and sanitary condition."
Previously, the 9th District Court of Appeals in Akron found that a landlord's responsibilities didn't extend to guests.
That conflicted with a more recent finding by the 10th District Court of Appeals in Columbus in a case involving a teenager who fell through a glass panel at the bottom of an unlit staircase. That court found that the landlord breached his duties and was liable for her injuries.

I feel like I've been totally out of touch this week! I'm recovering from acute bronchitis, it's been a while since I've felt that bad! I didn't check Facebook or Email, only went somewhere if it was absolutely necessary (doctor, pharmacy, school). I still feel like I'm coughing up a lung, but I'm pretty sure I'm not dying! I couldn't say that for certain on Monday!
I hope everyone had a good weekend, I know that a holiday weekend can be a wonderful family time, and it can also be a time of bittersweet memories. Thankfully, I still have my mom, mother-in-law and grandmothers. I know it won't be that way forever, and I'm very fortunate to have them. This past week we traveled to GA where one of our daughters and son-in-law are stationed, and spent time with them and our darling grand-daughter for Mother's Day.
I wrote my Mailbox Monday and Teaser Tuesday posts before we left town, so I was able to simply post them, but haven't felt like doing much of anything since, compliments of the bronchitis. Today I'm up and around, and the housework is calling my name.
I've come across some interesting things online lately, and thought I'd share a couple of them.
Here's a neat article about book art at the WebUrbanist website. See some of the artwork below:
The art on the top left as well as the bottom left is done by Su Blackwell, top center and right is done by Thomas Allen, and the bottom right is a piece I haven't been able to credit yet. Another artist whose work I really like is Brian Dettmer's.
While I am too attached to books to use them even for the most beautiful art, I love these pieces. Their websites show a lot of other pieces they've done – just amazing! I love that books are such a fascinating medium. There are so many old books that no one seems to want that are stored, or left behind, it wonderful that they can be used for something so lovely. I've seen a lot of book crafts on Pinterest, and again, while they are lovely, I'm not sure I could cut up books. I grew up with a great respect for books, no matter their age. My mother wouldn't allow us to turn down the corner to mark our place (which is why I use almost any random thing as a bookmark), lay the books facedown while open, mark in them, or do anything else that might make them less than pristine. I had a hard time writing or highlighting in my textbooks, thanks to her!
Here's are some Pinterest finds using books:
A book/clock using Where The Wild Things Are
Here's a news tidbit that made me cringe, considering we spent a couple of days last week on the road and eating fast food – "Teen Finds Finger in Arby's Sandwich". I'm not a fan of fast food normally, but then when you read about stuff like this it makes me positively nauseous.
I have a few TV shows that I really like, I DVR them, then on a weekend, or unexpected downtime I watch them sans commercials. I came across a list of the shows cancelled in or after the 2011-2012 season. Some of my favorites are being cancelled – USA cancelled "In Plain Sight", TNT cancelled "The Closer", NBC cancelled "Harry's Law", FOX cancelled "Terra Nova" and "Alcatraz", CBS cancelled "CSI Miami", and ABC cancelled "Combat Hospital", "Expedition Impossible", and "Extreme Makeover: Home Edition". There is a show that's coming back that I'm excited about is ABC's "Secret Millionaire".
Review: Lean Mean Thirteen by Janet Evanovich
As the thirteenth book in the Stephanie Plum series, if you know Stephanie from previous books (or the One For The Money movie), you have a general idea about how this book goes. Stephanie just wants to do her job. Her job gets complicated. She gets in over her head. Ranger & Morelli work together to rescue her. And, as always – it's funny.
Stephanie was a lingerie buyer for a local department store, and when she got laid off she blackmailed her cousin, Vinnie, into giving her a job as a BEA (Bond Enforcement Agent) chasing down skips or FTA's (Failure to Appear). She has no training or experience, and another bounty hunter, Ranger, (ex-special forces military, who is totally hot and invests in stocks and real estate) mentors her, and adds an interesting triangle to her on-again off-again relationship with Joe Morelli, plain clothes detective who took her virginity behind a canolli case years before. Other characters: Lulu is an ex-hooker who was beaten almost to death, and changed her career path to file clerk at Vincent Plum's Bail Bonds. Connie Risolli is Vinnie's "guard dog" receptionist, and Grandma Mazur moved in with Stephanie's mom and dad after her husband died, and drives Stephanie's mother to drink.
The particulars of this book are that Ranger asks Stephanie to visit her ex-husband, Dickie Orr, and plant bugs in his office. Dickie is a lawyer, and the guy who, as the books say, cheated on her about 15 minutes after their marriage, and who she divorced about 15 minutes after that. When she goes to his office with her trusty sidekick's, Lula and Connie, she sees a picture of Dickie with her mortal enemy, Joyce Barnhardt, and goes nuts. She assaults Dickie in front of multiple witnesses. The next day Dickie has disappeared, leaving only a trail of blood in his house. The general public consensus is that Stephanie picked up where she left off at the law office, and eliminated Dickie. With Joyce generating theories about Stephanie's guilt and following her every move. With Dickie's law partners dropping like flies, disappearing then turning up dead, is Dickie going to show up dead next? Stephanie has no alibi – will this be the shenanigan that puts her on the wrong side of the law?
Other Reviews: Book Reporter, Read it, Read it, Loved it, Alison's Book Marks, and The Book Addict's Guide.
While all of Janet Evanovich's books are funny, I found this one less funny than most of them. I still enjoyed it, and am moving right on to Fearless Fourteen. So far I have rated this entire series as 4 out of 5 stars, but this one I rated 3 out of 5 stars.

The Arnold Arboretum's collection of plants in the genus Acer (maple) has been ranked as the most significant in the world for conservation purposes in a report released this fall by Botanic Gardens Conservation International (BGCI). Detailing the findings of a 2010 study of ex situ (off-site, or cultivated) collections of maples, the report gives top marks to the Arboretum. The analysis took into account the collections held by 228 institutions in 37 countries and was conducted as part of a broader effort to preserve threatened maples.
In 2009, BGCI and Fauna & Flora International (FFI) jointly published The Red List of Maples under the partnership of the Global Trees Campaign. This report named 26 taxa in the genus as endangered or critically endangered in the wild and called for additional efforts to ensure their conservation. To assess institutional efforts to protect maple diversity, BGCI then initiated a survey to determine which of these threatened taxa are held in ex situ collections worldwide—and which ones are not. Of the 4,405 maple records identified in the survey, 5% represent 16 of the most threatened species. The remaining 10 most threatened species are not known to be in cultivation at all, but can now be prioritized for collection. BGCI concludes its findings with an appeal to the botanical community to strengthen ex situ collections, implement programs for restoration and reintroduction, and involve communities in assisting conservation initiatives.
Maples continue to be an important genus for the Arboretum to collect, and were a primary target in a recent collecting trip in China by Curator of Living Collections Michael Dosmann. As part of its commitment to the North American Plant Collections Consortium (NAPCC), the Arnold Arboretum serves as the national germplasm repository for Acer as well as five other genera: Carya (hickory), Fagus (beech), Stewartia, Syringa (lilac) and Tsuga (hemlock). As a means to conserve biodiversity, the Arboretum maintains and develops these collections to maximize both inter- and intraspecific diversity.

Solidarity against online harassment
One of our colleagues has been the target of a sustained campaign of harassment for the past several months. We have decided to publish this statement to publicly declare our support for her, for every member of our organization, and for every member of our community who experiences this harassment. She is not alone and her experience has catalyzed us to action. This statement is a start.
The Tor Project works to create ways to bypass censorship and ensure anonymity on the Internet. Our software is used by journalists, human rights defenders, members of law enforcement, diplomatic officials, and many others. We do high-profile work, and over the past years, many of us have been the targets of online harassment. The current incidents come at a time when suspicion, slander, and threats are endemic to the online world. They create an environment where the malicious feel safe and the misguided feel justified in striking out online with a thousand blows. Under such attacks, many people have suffered — especially women who speak up online. Women who work on Tor are targeted, degraded, minimized and endure serious, frightening threats.
This is the status quo for a large part of the internet. We will not accept it.
We work on anonymity technology because we believe in empowering people. This empowerment is the beginning and a means, not the end of the discussion. Each person who has power to speak freely on the net also has the power to hurt and harm. Merely because one is free to say a thing does not mean that it should be tolerated or considered reasonable. Our commitment to building and promoting strong anonymity technology is absolute. We have decided that it is not enough for us to work to protect the world from snoops and censors; we must also stand up to protect one another from harassment.
It's true that we ourselves are far from perfect. Some of us have written thoughtless things about members of our own community, have judged prematurely, or conflated an idea we hated with the person holding it. Therefore, in categorically condemning the urge to harass, we mean categorically: we will neither tolerate it in others, nor will we accept it among ourselves. We are dedicated to both protecting our employees and colleagues from violence, and trying to foster more positive and mindful behavior online ourselves.
Further, we will no longer hold back out of fear or uncertainty from an opportunity to defend a member of our community online. We write tools to provide online freedom but we don't endorse online or offline abuse. Similarly, in the offline world, we support freedom of speech but we oppose the abuse and harassment of women and others. We know that online harassment is one small piece of the larger struggle that women, people of color, and others face against sexism, racism, homophobia and other bigotry.
This declaration is not the last word, but a beginning: We will not tolerate harassment of our people. We are working within our community to devise ways to concretely support people who suffer from online harassment; this statement is part of that discussion. We hope it will contribute to the larger public conversation about online harassment and we encourage other organizations to sign on to it or write one of their own.
For questions about Tor, its work, its staff, its funding, or its world view, we encourage people to directly contact us (Media contact: Kate Krauss, press @ torproject.org). We also encourage people join our community and to be a part of our discussions:

Putting a list up with full names may open up for targeted harassment? You do not think?
Indeed, one of the trolls
Indeed, one of the trolls involved has been doing precisely this for every name he can map to a Twitter account. Every name on that list asked to be there, though. Sometimes confronting sociopaths requires a measure of courage.
"One of the problems of Free
"One of the problems of Free Speech is that when folks use it, others can use it against them."
The principle enemy of everyone anywhere in the world who struggles to advance free speech and privacy (and social justice and ecological stewardship and uncensored political discussions and economic stability and...) is NSA, the (near) global adversary which collects and uses the entirety of communications of every person living or dead to advance its own evil agenda (which often conflicts with the mission of other US government agencies, a fact we can leverage in the political arena in order to try to defend ourselves). We must never forget that one of the weapons this global adversary often uses is highly organized non-attributable trollery informed by advice from psychologists who specialize in promoting paranoia and discord, i.e. trolls.
In the coming months, NSA's most rapid supporters (such as Rep. Mike Rogers) will be attempting to use incidents such as
* the cyberattack campaign targeting Sony
* the harassment campaign targeting Tor developers
to further its unceasing demand for even more surveillance and cyberwar powers. I am already seeing editorials in leading US papers which mention NSA intrusion into "strategic" routers in overseas telecoms in the same breath as cyberintrusions attributed to "Guardians of Peace", without seeming to notice that breaking into someone else's electronic device is illegal and just plain wrong. Wrong when GoP does it, wrong when China does it, and yes, dead wrong when NSA does it. We must oppose and expose arguments that "the ends justify the means", which is of course the very argument used by Russia and China and North Korea to defend their own censorship and cyberwar capabilities.
It seems notable that NSA has actually been collaborating with China in a UN effort to "normalize" censorship in international law, under the rubric of an alleged "national security" need to counter "online rumors". Anyone who knows anything about what the Chinese government classifies as "online rumors" will understand the danger to democracy posed by the lamentable fact that one result of globalization has been that, even as the Chinese and Russian economies have become more like the US economy, the ideology of the US government has become markedly more authoritarian over the past two decades.
NSA is not above mounting a cyberattack or harassment campaign, in a non-attributable fashion, and then using it to argue that it needs even more surveillance and cyberwar and indefinite detention powers to ensure that US citizens remain unscathed in the new era of cyberchaos it has itself created through projects like Stuxnet. (Again, not a rumor, but established fact since the Snowden leaks contain hard evidence of such activity.)
This is not to deny that sometimes a troll is simply an ordinary garden troll. But thanks to Snowden it is now established fact that FVEY agencies have repeatedly and specifically attacked the Tor community, so we must all bear in mind that as Tor developers or even as users, we are more likely than other internet citizens to be "selected" for targeted attacks.
If NSA succeeds in crushing Tor, it will be free to pursue an agenda of global totalitarianism without opposition from ordinary citizens. But if Tor survives, maybe, just maybe, we can eventually eradicate this evil agency (through political pressure on the US government and through technical countermeasures which can eventually render NSA uneconomical for the US Congress to continue to fund).
I have been reading and
I have been reading and thinking about the comments in this thread and in the related tor-talk thread. Several people have expressed concern about parts of the his blog post which Roger has since edited out (thanks!). But the concern remains.
I propose that the Project clarify the original blog post along these lines:
"Trollery relies on psychosocial vulnerabilities common to all people and to all communities. Unfortunately, it can be an effective means of disrupting a community when trolls succeed in isolating individuals in order to sow discord. Fortunately, it can be effectively countered when targeted communities simply join in making a strong statement of mutual support."
On a more personal note, to the people who have been targeted by these trolls: it might help to picture trolls as concrete statuettes, mere caricatures of evil standing in the rain making faces in the windows. The value of a statement of community support is that it shows that the real people in the community are on your side of those windows. I hope such mental imagery might help restore the proper perspective on trolls, which is that they should arouse amusement or irritation but never fear.
Years ago I wrote about the
Years ago I wrote about the internet for my master's thesis. At the time I was very interested in the remote aspect of the technology and the ability for people to instantaneously connect from great distances.
I also saw the potential for abuse.
The bottom line is that our modern culture is accepting of abuse on many levels, so it was a matter of time before it became a problem online. We really need to examine cultural attitudes topwards not only women, but all marginalized groups.
There is a growing, not diminishing acceptance of abuse of all people in this country, particular those with perceived low social status. As long as it is tolerated throughout broader society, it will manifest online.
But all in all I support the effort and will pass the word along
Kendra Moyer
The Snowden leaks establish
The Snowden leaks establish some pertinent facts:
* FVEY agencies persistently and directly target the Tor user community,
* FVEY agencies routinely employ sophisticated software and highly trained operatives for "information operations" in on-line forums,
* Among these are operations whose intent is characterized (in formerly top secret FVEY presentations) as sowing dissension in order to disrupt some community whose activities are viewed as threatening to the state (for example, Wikileaks),
* Specific methods employed are known to include making defamatory claims about some members of the group to other members.
So these agencies clearly have the *ability* to troll the Tor community. But what would be their *motive*?
One plausible motive is the strong desire in CIA and NSA to prevent the prosecution for war crimes of people directly involved in kidnapping, torture, and assassinations:
The recent feature film "Zero Dark Thirty" lionizes a fictionalized version of Bikowski. I don't think enough is yet known about CIA/NSA counteroffensives (in the political arena and on-line forums) to say that this film is part of CIA "information operation" intended to influence world opinion, but I think there are ample grounds for suspicion. Nor do I think enough is yet known to say that USIC is behind the harassment campaign discussed in this thread, but I think there is sufficient evidence to warrant bearing this possibility in mind as the situation develops.
This is a critical time for the rogue agencies; there is a real possibility that some of their agents will face prosecution and even that the agencies will lose funding, especially as more sources contact journalists to tell what they know about state-sponsored criminality. Tor and Tails are technical tools which continue to play critical roles in enabling responsible journalists to cover these stories. It is already clear that CIA/NSA are desperate to cover up their crimes, and I think it makes perfect sense that they would try very hard to obstruct any activities which might help to ensure that the dark truth ultimately emerges from the shadows.
Among the hundreds of journalists who knew Bikowsky's name, only Glenn Greenwald and Peter Maass had the courage to finally publish it, for which they deserve our fervent thanks, precisely because, as several people pointed out above, in any civilized society governed by the rule of law, people who commit extremely serious crimes must be brought to account. It seems noteworthy that Greenwald has been a target of the USIC for years, no doubt because our enemies are terrified by anyone who refuses to be cowed by state power. We need more journalists like that, and more technical tools to protect their sources and to enable their vital work.
"One of the problems of Free
"One of the problems of Free Speech is that when folks use it, others can use it against them."
True; see "significant threat to the preservation of the anonymity of Tor users" in
DARPA has funded unclassified academic research on both stylometry attacks and on possible defenses, such as anonymouth.
Their motivation for funding stylometry attacks is obvious, and verified by their unclassified statements: USIC is deeply concerned about citizen researchers who use "open source" documents to research and expose the nature and extent of the Surveillance-Industrial complex, in part because such research necessarily includes analyzing the interpersonal relationships of key figures in USIC and in the private companies on which it relies, which can result in exposing the identity of USIC operatives. But why would DARPA also fund research into *defenses* against stylometry? The answer is of course that USIC operatives themselves extensively employ anonymous postings in various "information operations" intended to influence public opinion or to alter the behavior of people who threaten to expose state-sponsored criminality. So the USIC feels a need both to deanonymize "opposing" posters using stylometry attacks, and to defend their own operatives against exposure using such attacks.
The consequences of deanonymization can be severe:
Unfortunately, USIC agencies are by no means the only US government agencies who wish to defeat open source projects like Tor which can enable citizens to assist journalists in exposing state-sponsored criminality while reducing the likelihood of reprisals.
It is now widely appreciated that in the realm of electronic surveillance, the advance of technology has enabled intelligence agencies to broaden the scope of real time surveillance from the political leaders of hostile states to... essentially everyone. In the same way, technical advances have enabled US agencies to broaden the scope of computer modeling of the cognition, emotions, and behavior of individual persons (and their reaction to proposed USG policies) from world leaders to... essentially everyone.
It is now possible for US agencies to simultaneously model millions of individuals (and their interpersonal interactions and their reactions to local governmental policies), seeking to determine which among a list of alternative proposed policies and/or "targeted interventions" can most effectively influence civic trends and/or the behavior of individuals flagged as allegedly potentially posing future threats of various kinds to "state interests". Some notion of the original motivation for and sophistication of such modeling can be found here:
Relevant buzzwords include "threat scoring", "predictive analysis", "algorithmic governance", and "suasion operations". Companies currently marketing such programs to the USG include IBM, SAS, and Palantir.
Threat scoring has rapidly evolved from computer modeling which targets alleged "terror networks" outside the USA (and spammers and credit-card scammers) to modeling which targets US citizens such as PETA activists and fracking protesters. The first tentative steps toward implementing such systems on a wide scale have already occurred, with little fanfare in the press (excepting specialized newsletters intended for LEA employees):
It is notable that in an interview in Der Spiegel, John Podesta (author of the eponymous report on Big Data) specifically said that such precrime threat scoring is the aspect of the "new Jim Crow" which most concerns him. From
"SPIEGEL: In your report on NSA and "big data" for President Obama, you describe the potential opportunities and threats of this technology. What dangers do you see of big data in the hands of a surveillance system like the NSA?
Podesta: I think about it more in the context of law enforcement. You begin to -- particularly with predictive analytics -- blur the line between the presumption of innocence and targeting individuals. We are in a constant state of both adopting the technology and trying to formulate policy that is consistent with a value base that respects civil liberties, respects the integrity of the person and respects the need to ensure non-discrimination. The technologies are powerful tools to both enhance those rights of freedom and expression. But there is also a dark side to all of this, too. It has the potential to have a chilling effect for the government to hold that much data. So it's a struggle to get the balance."
This rapidly evolving threat to the freedom of speech of ordinary citizens is just one more reason why everyone should use Tor when posting comments. And don't forget that the USIC intends to store everything for decades, and a comment which does not appear "controversial" today might easily be portrayed as "criminal" tomorrow.
Concerning links: one notable aspect of the Barrett Brown prosecution is that if federal prosecutors get their way (and in the US "justice" system they generally do), a legal precedent will be established ensuring that anyone who simply posts a link may incur the threat of a long prison sentence. This would represent a significant victory for those who seek to prevent the exposure in the press of corruption and state sponsored criminality.
Concerning expensive governmental programs which have no chance of success even on their own terms: even Wikipedia articles clearly expose why NSA/CIA/LEAs will never be able to accurately predict who will commit some rare criminal action years in advance. The underlying mathematical phenomenon is precisely the same as is often discussed in tor-talk in connection with discussions of traffic analysis, and in the wider world, in connection with programs which attempt to screen the general population for rare diseases. The problem is that almost all of the people who "test positive" do not in fact have the disease. In the same way, most events flagged by stateful firewalls are false positives, and most people flagged as "potential threats to LEA officers" do not actually pose such threats. Roger sometimes call this the "base rate fallacy" but this term is too imprecise.
And so it begins.
And so it begins. From
"At least one type of information should be shared with U.S. critical infrastructure and financial firms—the IP addresses of Tor network nodes. Tor is a global network that helps users maintain anonymity by obfuscating users' true online locations. While it has many benefits, it is increasingly used to hide criminal activity online. The recent cyber attacks against JPMorgan Chase and Sony Pictures Entertainment highlight the need for such information sharing.
Tor, like other anonymity networks, has many legitimate uses. It is used by journalists, human rights defenders, and pro-democracy activists in countries where censorship is common and Internet access is tightly controlled and monitored. However, as cyber attackers become more sophisticated, they may use the Tor network in more cyber attacks, and use it to exploit the data they capture from critical infrastructure and financial firms. This will make it increasingly difficult for defenders to track and protect against cyber intrusions. There is no reason why legitimate bank customers, studio employees, or others that need to communicate with private firms like Sony Pictures or JPMorgan would need to use Tor. The U.S. government should provide the information it has on the constantly changing set of Tor nodes that exist around the globe. Tor IP addresses could then be blocked to prevent potentially damaging cyber attacks in the future."
Notice that Gonzales is proposing to share the IP addresses of *entry guards and relays* as well as exit nodes.
China, Russia, USA continue to move closer together in their attitude towards Tor. What a tragedy for democracy.
Regarding proposals such as
Regarding proposals such as this:
If thwarting banking cyberheists were the true goal here, there would be no need to for anyone but banks to block any IPs but the IPs of exit nodes, and these are publically available from Tor Project itself (updated every hour, even).
Yes, I agree. In fact, not
Yes, I agree.
In fact, not only do we publish the directory information (both current and historical -- see metrics.torproject.org), we also offer a service designed for law enforcement (and relay operators after the fact) if they want to look up a given IP address and time:
Also, I think the article (including Brian Krebs's article) misunderstands the data around number of bank attacks that involve Tor. I hope they actually publish the underlying report and numbers, so we can look for methodology errors like "we looked at the 1% of the attacks that seemed most unusual, and we found that many of those were Tor connections, therefore many of the whole data set of attacks are Tor connections."
Can the information you
Can the information you collect be used to reconstruct Tor routes after the fact? To identify hidden services? Could a hostile government use it to identify dissidents?
We don't think so. This is
We don't think so.
This is one the research areas that Tor has been working in for years -- how to collect useful public statistics about the Tor network without putting any users at risk. See
as well as one of the early research papers on exactly this topic:
I read that rand.org article
I read that rand.org article just yesterday, and saw flaws in it.
1. Overstating the role of tor.
If I understand the third paragraph correctly, the tor network was not directly involved in transporting the data away from Sony's servers, rather this was done using Sony's own playstation network. Only afterwards was tor then used, in a secondary manner merely to upload the data to file-sharing websites.
Taking this story as presented, it doesn't really make sense, especially the implication of tor being the critical problem. Why not use tor to extract the movies directly? Maybe because tor couldn't cope as easily as the playstation network with handling "perhaps several terabytes" of data in a timely manner? Maybe because playstations can download movies, and so large transports through that medium would look innocuous?
So the whole thing was found to be masterminded from a luxury hotel in Bangkok, Thailand, by "IP address sleuthing". The article doesn't tell us if a tor exit node was set up inside the hotel and happened to be used, or was deliberately used, or the mastermind was actually a pseudonymous client of the hotel and its wifi network. What was that post above saying about Thailand being a strong base for covert US operations again?*
"This circuitous route was used to mask the trail of the attackers and to enable large amounts of stolen data to be stealthily removed from the Sony network."
Really? The article just stated that tor wasn't the transport used to remove the data, and seems to assert it was definitely masterminded from Bangkok. It seems that tor was used only in part of the operation and maybe not enough of it or in the right parts, yet it gets all of the blame.
I can only conclude this article was written to meet a pre-formed opinion.
2. Tor node IPAs.
Yes, it seems the author is unaware that lists of tor exit node IPAs are public information. Or, maybe he hopes others remain unaware of this, perhaps he is hoping to win the government contract to run the dissemination service?*
"Notice that Gonzales is proposing to share the IP addresses of *entry guards and relays* as well as exit nodes."
I don't read that. Only the exit node IPAs need to be listed and blocked, surely? The rest is wasted effort.
3. Legitimately logging into a bank account with tor.
OK, here goes my main point ...
"There is no reason why legitimate bank customers, studio employees, or others that need to communicate with private firms like Sony Pictures or JPMorgan would need to use Tor."
"If thwarting banking cyberheists were the true goal here, there would be no need to for anyone but banks to block any IPs but the IPs of exit nodes ... "
Good counterpoint, but ...
When I became mentally ill, I wanted to research my illness, but keep its existence secret (stigma, employability, etc.). There was a problem though: recents laws meant my ISP was required to log which websites I was visiting, and store these for some time. The astute will get the privacy threat model. TAILS, thus tor, saved me there.
Recently, I spent several months in a mental hospital. Restriction take away many freedoms when you are there. Astonishingly, most patients had their mailing addresses changed to c/o the hospital, even for their banks, just to get their mail while being detained. Of course, I did not follow suit, wondering what my bank would make of me and my credit worthiness upon noting that I must be suffering from a mental illness. I still needed to access my bank account, and at least the hospital did provide internet access. What would happen, though, when I logged into my bank account? The IPA would no longer be that of my home, but what would my bank see? Again, the astute will get the privacy threat model.
I was lucky, the staff let me boot up TAILS (though I'm unsure most knew what I was really doing).
Maybe the hospital actually obfuscates the IPA for privacy. Maybe the bank does not really care to inspect the IPA. I doubt it. Try actually verifying this with hospital or bank staff, or their IT partners, and you're on your way into a Franz Kafka novel. There is no way to tell.
So, there you are, all, a legitimate reason to log into a bank account from tor.
Mr. Dingeldine, another 'use case' for you! Did you or anyone else expect that one?
Anyway, this is straying from the topic of this blog, and relates much more to the blog about tor being targeted. In my next post, I'll bring relevancy back by discussing censorship.

* Conspiracy theories are soooo easy to make up!
"We support freedom of
"We support freedom of speech, but" is right there with all other "I am/am not a ..., but" sentences.
Right you are. I was
Right you are. I was answering this for somebody else, so I'll answer it here too:
Q: Doesn't being anti-harassment mean you are against free speech and pro-censorship?
A: No, it doesn't. We're fans of free speech and that means we're against censorship.
I really like the way Professor Jean Camp explains this apparent contradiction:
"""Threats are not about speech, they are about silencing. Threats are the opposite of dialogue. If a small minority of men can silence a great number of women, speech is not served. Any person who is silenced by threats of violence is damage to free speech.
Anonymity can and is targeted at supporting speech. Threats can and are targeted at silencing speech."""
Our statement against harassment is meant both as a gesture of support, and to raise awareness about the issue and try to get all of the neutral people in the middle to be mindful about it when choosing their behavior. The answer to bad speech is more speech.
This post is vague. If a
This post is vague. If a person states that rape happens often and is awful but at the same time he/she does not believe that x or y woman was raped in any particular case, such as the U-VA rape allegation, will Tor retaliate by denying him/her privacy?
I think we need more specificity as to which way Tor is headed.
Does Tor intend to
Does Tor intend to de-anonymize users believed to be engaging in online harassment?
No. We aren't advocating
We aren't advocating removing protection from harassers. We didn't mean that we will undermine Tor or retaliate by escalating the harassment or involve government authorities to punish harassers.
Rather, the statement is about how we are now going to stand up and participate and discuss and engage with the topic of harassment and not stand quietly by, hoping somebody else will deal with it.
Some supporters have suggested that we change "not tolerate" to "not support" to avoid these misunderstandings. The problem with "not support" is that it allows us to say "This is wrong; I will contribute to fixing it by not participating." And that's exactly the response that's gotten us, the Internet community, to this point. Instead we need to contribute to fixing it *by participating*. That's what this statement is all about (and why it says "this is a start").
I see. All good then.
I see. All good then.
This is what I wanted to
This is what I wanted to see. Thank you for your comments. At this point it seems that we cannot expect technology projects to not toe a political line, but as long as you continue to provide your service with no respect to political views I can continue to support you.
Way up above there
Way up above there somewhere, someone wrote that censorship is a necessary evil.
There is an ethics argument that you only know you are a good person if you have the potential to do evil deeds, but choose not to do them.
Tor is a tool that gives people the potential to do good deeds and evil deeds. It is our choices that define us, not tor.
If you censor evil deeds, how do you know people are now good? You can't (unless you are that 'privileged watchman', rather than the protected victim). Better is to allow people (and tor) to carry on and see what the outcome is. Better is to give the trolls their chance to be a troll. Only then, when it goes 'quiet' and things are civil, can we really say that the behaviour of people has reached a better standard.
Maybe trolls will always be here, but if we don't try it, how will we ever know we can reach that better standard? Any other way, censorship, harrassment, bullying, stupidity, are manners of failure preventing this.
In the meantime, when trolls do troll, we can speak out, document, complain, ciriticise, etc., to appeal to intelligence to select the better arguments. Doing that is taking a stand, but it is not consorship. It is the opposite of censorship.
In the end, we will get what we deserve, because it's a tautology really, which is a much better way to run things: tautologies never fail. :)

One irony of the December
One irony of the December 2014 Sony megaleak is that Sony acquired the rights to the Snowden movie
(The email discusses a forthcoming news release which was published in May 2014. The nonpublic talking points are the content which was published as part of the leak.)
The only truly newsworthy part of the Sony megaleak is that the leaks confirm in detail what many have long suspected: that Hollywood actively collaborates with CIA in producing propaganda films such as "Zero Dark Thirty".
This instance of midwestern zaniness is comparable to
I agree with Straggler that
I agree with Straggler that the Tor Project should prominently debunk the RAND blog mentioned above:
Many people in USG pay attention which RAND issues recommendations, even when its advice is highly questionable. (If memory serves, one of the most notorious past recommendations from RAND was its technocratic judgement, during the Reagan presidency, that one complete multimegaton thermonuclear detonation occurring in the USA every twenty years would constitute an "acceptable" rate of lethal mishaps involving US nuclear weapons. The good citizens of Kansas might beg to disagree.)
I think the Project should request an unredacted copy of the secret report issued by Financial Crimes Enforcement Network (FinCEN), which is part of the US Treasury Department, on 2 December 2014, alleging that Tor nodes are used in a large fraction of the most dangerous attacks on the US financial infrastructure. Brian Krebs says the he was given a copy of this report, which he describes here:
According to Krebs, the authors of the FinCEN report searched "6,048 suspicious activity reports (SARs) filed by banks between August 2001 and July 2014" for mention of the IP addresses of 6000 known Tor nodes (not just exit nodes?). Krebs says "investigators found 975 hits corresponding to reports totaling nearly $24 million in likely fraudulent activity", but does that mean 975 of the 6048 SARS reports mention the known IP address of some Tor exit node, or that 975 of the known IP addresses of roughly 6000 Tor nodes are alleged to appear in SARS reports? Did these "investigators" even check that the machines with the suspect IP addresses are even listed as Tor exit nodes functioning during the time frame of the SARs reported incidents?
There are so many unanswered questions here that it is impossible to put any credence in the allegations publicized by Krebs unless he provides much more information about the evidence presented in the FinCEN report.
Krebs appears to cite this post from the Tor blog
as evidence that Roger acknowledges that it is "necessary" for banks to block Tor exit nodes by IP, while seeming to acknowledge that Tor may have legitimate uses. But I think he may have misunderstood Roger. For example, consider the predicament of a US embassy employee who wishes to check his/her bank balance in a US account without tipping possibly hostile local ISP employees that the person associated with a particular local IP address banks at a USG credit union? Such a person might be tempted to use Tor to contact the banks webform (after all, the username and password are presumably protected by a properly configured and fully patched TLS connection).
On the issue of cybersecurity, I don't yet see any reason to conclude that Krebs is necessarily an ideological opponent of Tor, but I do see plenty of evidence that the Project should be trying to educate him about how good citizens use Tor.
Calling for the USG to encourage sites to block Tor nodes is like calling for the USG to recall the F-150 pickup truck (stamped "made in America") on the grounds that almost 20,000 US residents are killed each year in vehicular accidents, many no doubt involving the F-150.
Incidentally, Krebs just published a follow-up on the DPRK issue:
in which he concedes that "a sizable number of readers remain unconvinced about the one conclusion that many security experts and the U.S. government now agree upon: That North Korea was to blame" and presents further arguments for attribution to DPRK. His first try is convincing everyone DPRK is to blame can be found here:
I don't think Krebs is being accurate when he implies that all the "experts" have accepted the DPRK attribution, while only "a sizable number of [inexpert] readers" continue to express doubt. There are plenty of seasoned cybersecurity experts who are also continuing to express doubt.
Some of the circumstantial evidence Krebs presents could, I argue, be more reasonably interpreted as evidence for a different attribution. For example, he writes:
"It is interesting to note that the attackers initially made no mention of The Interview, and instead demanded payment from Sony to forestall the release of sensitive corporate data. It wasn't until well after the news media pounced on the idea that the attack was in apparent retribution for The Interview that we saw the attackers begin to mention the Sony movie."
This kind of ideological confusion or backtracking could be regarded as weak circumstantial evidence for the hypothesis that the 2014 megaleak is due to cyberhacktivists, perhaps assisted by disgruntled Sony employees (one might cite the precedent of the HB Gary Federal leak).
Krebs says
"Both of those terms reference the military classes of ancient Rome: "hastati" were the younger, poorer soldiers typically on the front lines; the "principes" referred to more hardened, seasoned soldiers. According to a detailed white paper from McAfee, the attackers left a calling card a day after the attacks in the form of a web pop-up message claiming that the NewRomanic Cyber Army Team was responsible and had leaked private information from several banks and media companies and destroyed data on a large number of machines."
Many literate people read history, and some occasionally adopt a nomme de guerre referencing ancient Roman history. This "evidence" could also be misinterpreted as evidence that Someone was trying to frame Edward Snowden for these cyberattacks.
Ironically, one of the bloggers whom Sony threatened in retaliation for discussing material from the leaks was... Brian Krebs. Further evidence that Sony is possibly the most clueless corporation on the face of this planet.
If only there were more
If only there were more people on this list. The thing I find most concerning with online harassment is the fact that people think they can treat you differently if they can't see you. Just go on YouTube and watch any prank/social experiment with the pranksters telling Facebook comments randomly to people in the street; just watch the reactions.
Thanks to the Tor volunteers
Thanks to the Tor volunteers and staff (Atagar and maybe others) for so quickly detecting and mitigating the attempted Sybil attack earlier today!
Thanks to Wikipedia volunteers for so quickly updating this article:
(Tiny quibble: as I understand it, Thomas White is a Tor volunteer but not a Tor staffer.)
Please correct me if any of the following are wrong:
* in the hour before 1430 hours on Fri 26 Dec 2014 UTC, about 3000-3500 new Tor nodes suddenly appeared
* the new nodes all have nicknames beginning "LizardNSA", and all but a handful share the tld googleusercontent.com
* all the Lizard nodes all had low bandwidth (or was the bandwidth manually zeroed by Tor staff action in the consensus?)
* within one hour, this was identified as an apparent Sybil attack and the new nodes were blacklisted
* yes, Lizard Squad briefly operated about "half of all Tor nodes"
* no, that's no cause for panic, because Lizard Squad never controlled more than a fraction of 1% of the total bandwidth
* the nodes were configured as Exit nodes but were also configured to "sinkhole" all traffic
* Lizard Squad posted a few messages to tor-talk from a riseup.net account which did not appear to offer a plausible explanation of their intentions
(Poorly?) informed speculations:
* crude (and unworkable) DDOS targeting Tor?
* an (unworkable) massive deanonymization attack on Tor users?
* someone trying to frighten ordinary or potential new Tor users with bad news stories claiming that "Tor is broken"? [sic]
* someone trying to frighten or obstruct a small group of Tor users for obscure purposes with no relevance to the wider community?
* someone trying to give FBI an (absurd) "excuse" to NSL riseup.net?
We do know from Snowden leaks that a well established GCHQ tactic against Anonymous type disorganizations is to try to frighten away potential "associates" by tying certain domains or certain kinds of political activism to illegal activities. We also know that USIC and its allies tend to try to "justify" their surveillance dragnet by claiming that they have a "need" to predict whether or not peaceful political groups are about to turn "violent". So once again, Tor has been (maliciously?) "implicated" in a well publicized event which seems to benefit only the surveillance-industrial complex.
I would not discount the possibility that all these events are NSA or its allies mounting "false flag" attacks, but I am increasingly inclined to speculate that the most likely explanation for most or all of them is a small politically unaffiliated "hacking" [sic] group.
With respect to the discussion above of a possible connection between Gamergate and the harassment of Tor developers, it is intriguing that according to Wikipedia, Lizard squad
* previously targeted Sony a few months ago
* claims responsibility for taking down DPRK's internet a few days ago
* claims responsibility for DDOS attacks on two major gaming sites earlier this month and a few days ago
"Even Wikipedia articles
"Even Wikipedia articles clearly expose why NSA/CIA/LEAs will never be able to accurately predict who will commit some rare criminal action years in advance":
Thanks to James Ball for explaining this point in his recent "Comment is Free" piece in The Guardian:
Unfortunately, Ball failed to mention the fact that Gen. Hayden revealed years ago that Bayesian inference using communications metadata (and modeling of the kind discussed in the IEEE Spectrum article) has been used for years by NSA in drawing up the targeting lists for drone strikes. As Hayden put it (quoting from memory, so this may not be the exact quote), "we kill people based on metadata" [and computer modeling]. Charming. I wish reporters would ask the academics cited in the Spectrum article to explain why their work is not morally equivalent to the work of the now infamous "torture shrinks".
I hope that all other reporters covering the internet know all about Bayes's formula and the failure of Bayesian inference in the presence of a tiny base rate. If not, the Tor Project should make sure to teach them. There are further serious errors governments are likely to make, if we let them, but let's start with the simplest error.
Following up on the point
Following up on the point made above that when P stalks Q, it is not always true that P is a man and Q is a woman:
'The files have been heavily censored, but still manage to show that, either by accident or design, NSA staff routinely engaged in illegal surveillance with almost no comeback from management. Take, for example, the case of a female analyst who used the NSA's vast databases to conduct a little research on her husband. The report covering the first quarter of 2012 states that she accessed her hubby's personal telephone records to look for possible "targets," over a period of three years, and when found out was "advised to cease her activities."'
I see two possibilities, neither of which helps NSA defend against the growing clamor to simply eradicate this rogue agency:
1. no-one at NSA ever gets more than a "girls/boys will be girls/boys" snigger from the (male/female) boss,
2. Madam LoveInt *was* the boss (one imagines a breathless headline in the Crystal City Courier: "Teresa splits from James").
To those with knowledge of the details of loveint episodes, should the Lizard have no objection, might I suggest using Tails to contact journalists? If you don't like The Intercept, try The Hollywood Reporter.
The Register notes ACLU "was only able to file the request thanks to knowing specifically what to ask for, thanks to internal documents leaked to the world by Edward Snowden".
Once again, a heartfelt thanks to Snowden, who used Tails (and thus Tor) for the purpose intended. May his example further inspire our Fifth Column!
As further evidence that the
As further evidence that the troll campaign has failed: Tor and Tails just received two high profile endorsements:
Thanks to Wired and El Reg!
Roger's blog confused at
Roger's blog confused at least some non-gamers who initially had little idea what he was talking in this paragraph:
"The Tor Project works to create ways to bypass censorship and ensure anonymity on the Internet. Our software is used by journalists, human rights defenders, members of law enforcement, diplomatic officials, and many others. We do high-profile work, and over the past years, many of us have been the targets of online harassment. The current incidents come at a time when suspicion, slander, and threats are endemic to the online world. They create an environment where the malicious feel safe and the misguided feel justified in striking out online with a thousand blows. Under such attacks, many people have suffered — especially women who speak up online. Women who work on Tor are targeted, degraded, minimized and endure serious, frightening threats."
While the Gamergate harassment campaign may not be directly related to the harassment campaign obliquely referred to in the statement of solidarity, the following two items may clarify the reference to "serious, frightening threats":

Hi, Women are human beings,
Women are human beings, and as such, they have the right
not to be discriminated against. The same apply for all
human beings.
In order to fight the discrimination, I think the best way
is to hit it where it's the most painful for it:
We should not silence the discrimination but instead fight
it back by shaming the ideas behind it and the people who
do it on the basis of the wrongfulness of theses ideas.
I think it is way more effective, and it doesn't raise any
free speech issues at all.
As a side note, many women are extremely competent, and the
reason why they appear not to be is only due to the
consequence of the discrimination. The same apply for
all kind of discrimination.

Map 2: Aerial view of the Florence Stockade, the Florence National Cemetery and the campground of the Confederate guards.(USGS National Agriculture Imagery Program [NAIP])
This map shows the location of the Florence Stockade, the Florence National Cemetery and the area where archeologists located the campground of the Confederate guards.
Questions for Map 2:
1) Use the scale bar and measure the distance in meters from the Stockade to the original location of the Florence National Cemetery. What problems do you think the prisoners who had to bury the dead had in transporting the bodies that distance? Why do you think the Confederates chose that spot to bury them?
2) Examine the area west of the Confederate Camp. Based on what you can see on the ground, do you think that archeologists could find more of the camp in that area? Why or why not? (Refer back to Reading 4, if necessary)

Last week, a ten-year-old Alexandria, Virginia, boy was arrested and charged with brandishing a weapon, according to The Washington Examiner. This is a very serious charge that will stick with the boy. The "weapon" that the fifth-grader brought to school was a plastic toy gun with a bright orange cap on the end of the barrel. He never threatened anyone with it, and never pointed it at anyone.
This boy now has a criminal record. For the rest of his life, he may have to disclose that he was arrested, even if his juvenile file is sealed for most other purposes—just for bringing a toy gun to school.
After the recent school tragedy, it is understandable that school administrators are on edge about guns in schools, but it does not excuse them from being rational.
There have been a number of incidents involving fake or imaginary guns in schools recently. Kids have been suspended from school for bubble guns, Nerf guns, Lego guns, pictures of guns, and fingers pointed like a gun and saying "pow," just to name a few. One thing those incidents have in common is that the school handled them internally. It can be debated whether the schools overreacted by suspending the students, but at least they didn't call the police.
A police record can have a damaging affect on a person's life. This charge can potentially affect the high school jobs he can get, the places he can live, and the college he attends. This isolated incident may even affect the jobs he can get after college; especially if he chooses to be a teacher, doctor, lawyer, law enforcement officer, or join the military.
Does it make sense to potentially alter this ten-year-old boy's future in so serious a manner, all because he brought a toy gun to school? If he attempted to pass the gun off as real and used it in a threatening manner, that would be a different matter, but adults and kids generally also know that an orange cap means it is a toy.
However, it was still foolish of the child to bring this particular toy to school. A reprimand or other internal school disciplinary action would be in order, but, in this case, there is nothing to suggest that he harbored any criminal intent or meant to harm anyone.
Everything that we do should serve a purpose. What purpose does arresting and charging this ten-year-old child serve? It doesn't protect anyone—no one was ever in danger. It may deter the boy and his classmates from bringing toy guns to school—but a suspension would have as well.
The criminal law must be reserved for serious wrong-doers with criminal intent, not foolish children who bring their toys to school. Charges like these needlessly label children as criminals and may set them up for unwarranted struggles in life or perhaps, if they spend time in jail associating with and befriending real criminals, a life of real crime.

Polly want a home?
When people think of animal shelters being inhabited by homeless animals, dogs and cats are the typically the pets that come to mind. Unfortunately, there are just as many unwanted birds in need of a loving home. Overrun with the more common pets, like cats and dogs, animal shelters often cannot appropriately cater to these abandoned birds' needs. This is where bird rescue foundations swoop in to save the day.
"Organizations have taken on this challenge of rescuing unwanted birds and providing forever homes or placing them in pet homes," said Dr. Jordan Gentry, a veterinary resident instructor at the Texas A&M College of Veterinary Medicine & Biomedical Sciences. "Depending on the organization, there may be strict requirements to meet before even being considered as a bird adoption home."
If you're contemplating bird adoption, requirements typically include extensive applications, adoption fees, and possible veterinary costs. "Additionally, some organizations only allow adoptions to people within a certain local area," said Gentry. "Adopting a bird easily costs more, requires more work, and will limit you to only birds that have been given up for adoption; however, sometimes the right bird becomes available and occasionally people meet the requirements of adoption." Just keep in mind that many relinquished birds could have severe behavioral problems, such as biting and aggression that led to them going into the rescue center in the first place. Make sure you have the right environment for the bird, as well as the time and patience to care for their specific needs.
If you're willing to accept the challenges and have met the specific requirements, there are several preparations to make prior to Polly's arrival. "If you have done your research, you can have the cage set up in advance and take some steps to make your new bird's transition easier," said Gentry. "Most of the adoption organizations will have plenty of recommendations or requirements before you will be allowed to take the bird home." And like with your other pets, you should take your new bird in to be seen by a veterinarian within the first seven to ten days in their new environment.
There are various organizations in the United States to find rescued birds in need of a caring home. Located near College Station, there is The National Parrot Rescue & Preservation Foundation, adopting birds in Houston and the surrounding areas. The Gabriel Foundation in Denver, Colorado is another well-known parrot adoption venue. "In addition to these options, pet birds are occasionally available from other venues such as classifieds, Internet forums, or even through A&M Zoological Medicine Service," said Gentry. "Remember that it is always important to research any bird species you are considering bringing into your home."
While bird experts and enthusiasts may be the perfect fit for taking home a new winged companion, remember that bird ownership is not for everyone. Adopting a pet bird from a rescue foundation means adopting all of the difficulties previous owners have created in the past, so be sure that you're willing and able to provide for them. If you do have the time and patience to care for these beautiful creatures, though, then providing them with a forever loving home, and maybe a few crackers, can make both you and Polly very happy.
