Superman: Unchained (and crazy busy)
Man of Steel, celebrating his 75th birthday, is everywhere!
Superman has super powers -- it's right in his name, after all -- but shouldn't he be slowing down?
He's turning 75 this year, but the Man of Steel is crazy busy. He's in movie theaters with the umpteenth filmed account of his origins; he's roaming downtown San Diego, as one of the more popular costumes for Congoers; he's starring in DC's long-running "Superman" comic book; he's -- get this! -- a villain in "Injustice: Gods Among Us," an online game and associated digital comic; and now his broad, spandex-encased shoulders are carrying a new DC title, "Superman: Unchained."
"We wanted the story to be true to the title," said Scott Snyder, who is writing this Jim Lee-drawn series. "So we're putting Superman in situations you've never seen."
The second issue of "Unchained" is already out. Spoiler alert: things are bad and, for the Caped Crusader, they're going to get worse.
"We really want to tear him apart," Snyder.
Much as we love our Superman adventures, isn't this elder abuse?

Who is the greatest fighter alive? No. 3 revealed
THE RING magazine has produced an exclusive top 10 list of the greatest living fighters. Editor-in-chief Michael Rosenthal reveals No. 3 on that list.
THE RING magazine has produced an exclusive top 10 list of the greatest living fighters. Editor-in-chief Michael Rosenthal reveals No. 3 on that list.
WBO featherweight title holder Orlando Salido will defend his belt against Ukrainian Olympic gold medalist Vasyl Lomachenko on March 1 in San Antonio.
Mikey Garcia could make the first defense of his WBO junior lightweight belt on Jan. 25 against Juan Carlos Burgos. WBO lightweight titleholder Ricky Burns and his mandatory contender, Terence Crawford, could fight on the same card.
Tim Bradley, Juan Manuel Marquez and the others fighters on their nine-bout card on Oct. 12 tested negative for banned substances, according to the Nevada State Athletic Commission.
Undefeated featherweight Gary Russell Jr., who is the mandatory challenger for WBO titleholder Orlando Salido: "I'm ready for my first world title fight and can not wait for the fight to get made."
Ukrainian two-time Olympic gold medalist Vasyl Lomachenko scored two knockdowns during his fourth-round stoppage of Jose Luis Ramirez in his professional debut on Saturday.
The handlers of WBO light heavyweight titleholder Sergey Kovalev say the fighter has agreed to make his fist defense against Ismayl Sillakh on the Nov. 30 Adonis Stevenson-Tony Bellew card.
Openly gay boxer Orlando Cruz on dealing with homophobia in boxing: "I'm in a sport that is very macho. Sometime in the ring, people would should gay slurs at me before I came out."
Two-time Olympic champ Vasyl Lomachenko, who goes pro on Saturday, advises boxing fans to "be patient." "I will be doing big things and you'll be witnesses when I do them."
Juan Manuel Marquez will earn a guaranteed $6 million for his challenge to WBO welterweight titleholder Tim Bradley, who will pocket at least $4.1 million when they fight on Saturday at Thomas & Mack Center in Las Vegas.

Ukrainian two-time Olympic gold medalist Vasyl Lomachenko arrived in Los Angeles to begin his pro career. The featherweight star will fight on the undercard of Tim Bradley-Juan Manuel Marquez and if he wins, promoter Bob Arum has said the next fight will be for a world title.
Juan Manuel Marquez said he is "done" with Manny Pacquiao, which is why he chose to face Tim Bradley on Oct. 12 rather than a fifth fight with Pacquiao. Bradley, who turned down a rematch with Pacquiao, says Marquez is a "new challenge."

Issac Delgado went looking for the Latin soul of Nat "King" Cole and ended up discovering a Cole brother whom everyone should know.
The Cuban salsero grew up in the late 1960s and early '70s listening to Nat King Cole's hugely popular Spanish-language records, which earned him a vast and enduring following across Latin America. In the process of recording his new Cole tribute album "L-O-V-E" (Sony Masterworks), Delgado encountered Nat's youngest brother, Freddy Cole, a polished and encyclopedic jazz crooner and pianist.
While "L-O-V-E" is an homage to a legend who left the scene far too young (Nat Cole died of lung cancer in 1965 at the age of 45), the album also became a showcase for the younger Cole, who has quietly become a national treasure. Delgado, often referred to as salsa's Frank Sinatra, teams up with Freddy Cole at Yoshi's-Oakland for three nights (and one matinee), beginning Friday.
"Finding Freddy was really my lucky break in this production," says Delgado, 47, speaking in Spanish through an interpreter. "I knew the Cole family was musical, but I didn't really know about Freddy. My executive producer had just worked with him on a song for a film, and asked him about participating. He had never done anything like this before, a tribute to his brother. But Freddy really liked the project, and he was inspired to re-create this sound.
"He's one of those artists we don't have many of anymore," Delgado continues. "His voice is warm, and he transmits a purity, a simplicity. It's so easy to work with a true artist who's in the moment, who's creating and improvising."
Nat Cole's iconic status in Latin America stems mostly from three albums he recorded between 1958 and 1962. Though he didn't speak the language, he connected with the audience by phonetically crooning Spanish lyrics of Latin-American standards like "Perfidia," "Ay Cosita Linda," and "Piel Canela."
"Just like everything else that Nat did, people love him," says Cole, 78. "I think those were his biggest selling albums."
Delgado, who helped create the hard-hitting timba sound as the lead vocalist of the powerhouse Cuban band NG La Banda, pitched the Cole tribute project to Sony as his third U.S. release since defecting here in 2006. Like millions of others across Latin America, he grew up hearing Cole's Spanish sessions, but his fascination was sparked by encounters with Cuban musicians who worked with Cole during his long tenure at Havana's storied Tropicana club.
"One of the things I loved hearing about was how accessible he was to the musicians. Some of the best stories come from Óscar Valdés," Delgado says, referring to the percussionist who helped found Irakere. "He says that Nat King Cole was always very interested in weaving Afro-Cuban beats and feeling into his songs. And Óscar was always trying to get him to fix his pronunciation."
For Freddy Cole, developing an independent reputation in the shadow of a larger-than-life sibling has been a lifelong challenge. Nat's relationship with his younger brother was always close and somewhat paternal. Nat paid for Freddy's conservatory education, which started at Juilliard. But when it became clear that New York's nightlife was taking precedence over classroom studies, he persuaded Freddy to transfer to New England Conservatory in Boston (where he also proceeded to work all over town).
He earned valuable road experience as a pianist with Earl Bostic and Lionel Hampton, but always wanted to sing as well. Before he could establish himself, the British Invasion swept away the market for acoustic jazz, and Cole spent the late 1960s and '70s playing lounges, weddings, casinos, bar mitzvahs and any other gigs that came his way.
A slyly understated pianist and master ballad singer with a smoky, smooth delivery, the Chicago native is a throwback to the days when jazz and pop constantly renewed the other, and when singers like Sinatra and Billy Eckstine emerged from big bands and became independent stars. (His latest album is an Eckstine tribute, "Freddy Cole Sings Mr. B," on HighNote.)
Since the mid-90s, Cole has worked steadily with producer Todd Barkan (who owned the great North Beach jazz club Keystone Korner and now serves as programming director for Jazz at Lincoln Center's Dizzy's Club Coca-Cola), recording more than a dozen beautifully crafted albums. He is enjoying one of jazz's most productive late-blooming careers.
He used to express decided ambivalence about the burden of his brother's name, recording a 1990 album "I'm Not My Brother, I'm Me," which he concluded with a medley of Nat Cole hits. These days, he's embracing his brother's Latin American legacy, and not losing any sleep over fraternal comparisons.
"I'm very much at peace," Cole says. "It doesn't really bother me at all anymore."

You must have more than one column with 'S02' in the name. Do you want to
return all columns that have 'S02' in them or just one of them? If just one
of them, which one?

3. Media: reputation, loyalty, NPS... many way to measure the positive/negative virality of a customer for marketing. We think opinions for the media industry are important, and we would definitely like to contribute to empower each and every user with more powerful tools to express themselves. MySmark has this feature too, thanks to the widgets designed to keep into account users subjectivity while posting a comment, sharing a link or giving feedback. In other words, we would be able to understand the difference in between 2 like, given by 2 different users.
How many employees do you have now?
At the moment we have 5 full time people and some external collaborations.
We are planning to grow our organization in the coming months, looking at doubling it by the end of the year, in accordance with our new investors.
What's the biggest challenge you've faced so far? The greatest victory?
I think the greatest victory for such a venture is to be able to shape the vision and the direction of the journey every day, funnel in a lot of energy and empathy with your team, and help each of them to deliver. Externally it is fundamental to keep the public profile relevant with good PRs and continue the discussions and meetings with target customers and partners in order to really involve them in the idea development. As many (if not all) other startup projects we have got many ups and downs in the past 3 years. We have been able to pass through difficult times together and attract a lot of great people to back us in this project. I disagree with the motto "fails fast is better" since I think that no entrepreneur is prepared to fail. I agree with a good combination of lean approach and strong entrepreneurial motivation. Continuity is the greatest victory. Look at how many stories of entrepreneurs who decided to keep on doing even if the reality looked like a failure out there. Many of them did it, in desperate conditions. If you feel what you are doing is right, don't stop and do it.
What's been the most important lesson?
Most of the teams just think that their idea is unique and their product is the best, and all the world has simply to understand it. Well, after a while you realise that none of this is properly real, and that you need to go back and do a constant competitive analysis and prior art for your idea, try to make one of the best executions, and stay constantly in touch with your potential users and customers, since your product will need quite a lot of iteration and fine tuning. So the most important lesson to me is the need of changing a little something every day, and ultimately be flexible and realistic with your vision, which has to be connected with state of the art of innovation (Moore's Law) and rapid market changes.
What are your plans for 2014?
In 2014 our main target is to build the best showroom of use cases for MySmark and provide the team with the proper resources to boost the venture. We are working very close with irish and italian markets, and that is quite unique since we are one of the very few italian startups in Ireland (actually I don't know any other). On the other hand we think that UK and US can really be great opportunities for us, since we are positioning MySmark as a marketing proposition, and London-NY are 2 of the most important places of marketing decision making. So our idea is to be soon in both cities to promote our services and acquire new customers.
What advice do you have for other people/companies starting out in your industry?
Marketing is a crowded space. It is also at the crossroad of a huge metamorphosis, which will bring a lot of new opportunities. You can decide to catch a trend and go for an incremental innovation, or you can decide to fix in a great new way old problems. Especially if you start outside of US, I think you have to carefully build something new, unique and smart. We are trying to do it through S-marketing, smart marketing. Finger crossed :)

LOL @ "The bewilderment of the Christmas season." I never got this. Why do people complain so much about how hard and expensive Christmas is? You don't have to actually participate if it bothers you so much, holidays are supposed to be fun. Can you imagine? "With all of the stress that comes with labor day…" That sounds ridiculous, and to me, all the complaining about Christmas sounds just as bizarre and weird. If it's paining or straining you, cut it out! Stop it. Don't do things that you dislike, lol. Not that complicated.

And as Leible tells it, there's nothing like tasting a peach picked right from the tree.
"Most of the people that live around here are country-oriented and have had the opportunity to eat home-grown tomatoes and tomatoes from grocery stores. There's no comparison between the two, and it's the same with a peach," Leible said.
The transportation time from an orchard to a retailer can take away precious time in the sun for the fruit.
"Sunlight is what makes the peach sweet, and obviously peaches bought in stores can't hang on a tree as long as they do in my backyard," Leible said.
In order to be sold in stores, peaches must first be picked out of a field, stored in containers, transported and shipped thousands of miles to a grocery stores. There, peaches are put into a cooler and shelved, Leible said.
"Those peaches have to be picked pretty green and picked before they can absorb all of the flavors and sweeteners," Leible said. "Here, all the road time is left on the tree.
"I can leave them on the tree longer and wait until they're ready to eat," Leible continued. "Three hundred yards -- that's as far as my peach has to travel."
Located off exit four from Interstate 57 North in Mississippi County, the roadside stand sits in front of Leible's 800 peach trees known as Dogwood Orchard.
When Leible purchased his home in 2002, he also acquired the eight-acre orchard. The home's previous owner planted the orchard in 2001, and by 2003, Leible was ready to sell peaches. Leible said he decided to take on the orchard so he sought advice from local agriculture experts and even took educational courses to learn about the peach industry.
Leible, who owns the orchard with Angel Gilchrist, hand picks the peaches at sunrise every morning. He estimated he picks about four bushel per tree.
"I'm out there every day -- and I pick them every morning. If I pick them in the afternoon, they don't hold up as well," Leible said.
Peaches, which have fared well this year, are in season typically from mid-
June through August -- about 10 weeks, Leible said.
Leible's orchard contains 17 varieties of peaches -- three of which are white peach varieties -- and four varieties of nectarines.
Leible compared the difference between white peaches and regular peaches to that of yellow-meat and red-meat watermelons.
"It (the white) has its own unique taste. I guess the white peach has a smoother taste and softer texture," Leible said.
Residents from Charleston, Bertrand, East Prairie and Sikeston residents frequent the stand, and with the orchard located near the interstate, there's potential for out-of-state visitors, too.
"It varies but it's usually steady throughout the day," said Justin Warren, who mans the stand throughout the day, about business. "We get a lot of regulars."
Peaches are sold in half-peck containers. Once fresh peaches are purchased, consumers should take appropriate measures to ensure they preserve their peaches the best they can, Leible said.
First they have to decide if they want firm or soft peaches. For those who like firm peaches, they can put them in the refrigerator in sealed plastic bags, Leible said.
"If you want to soften them up, leave them on the kitchen counter in the house. When they get to the softness you want, put them in a plastic bag in the refrigerator," Leible said.
It's important not to put the bare fruit in the refrigerator because refrigerators take moisture out of the air, and if peaches aren't in an airtight container, they will shrivel up quickly, Leible said.
Dogwood Orchard's stand is open rain or shine, hot or not from 10 a.m. to 5 p.m. every day of the week.
Leible encouraged anyone who's never tasted a tree-ripened peach to do so before season's end.
"They've got an opportunity right in their backyard to have the freshest peaches around," Leible said. "A short drive will be well worth it."

One of the most complete p2p backup papers yet published. The use of 'claims' to ensure symmetric storage trades is clever and very useful. Nice performance analysis and discussion of limitations. Samsara builds on Pastiche, which used a Pastry overlay to do joins.
Claims in flud are similar to those in Samsara, but can use Kr instead of a secret passphrase P. Thus, the claims in flud are constructed as h0 = sha256(Kr,0),... hi = sha256(Kr,i).
Samsara uses replicas instead of coding, and thus has to salt each replica to prevent cheating. Although this is only a minor disadvantage in Samsara, flud avoids it completely.
Claim forwarding is one of the trickiest problems in Samsara, so the system avoids it as often as possible. In flud, we don't plan on implementing claim forwarding at all.

Reputation & Trust
Reputation in P2P Anonymity Systems
@inproceedings{rep-anon, title = Template:Reputation in P2P Anonymity Systems, author = {Roger Dingledine and Nick Mathewson and Paul Syverson}, booktitle = {Proceedings of Workshop on Economics of Peer-to-Peer Systems}, year = {2003}, month = {June}, www_pdf_url = {http://freehaven.net/doc/econp2p03/econp2p03.pdf}, www_section = {Economics} }
Details several reputation systems for use in an anonymous remailer setting and in an anonymous publishing system (Free Haven), but that are more generally applicable to all anonymous p2p systems. Discusses weakly trusted global witnesses, small groups of remailers (cascades), and storage contracts (with shepherds or buddies).
Select Quotes:
"Unlike confidentiality (encryption), anonymity cannot be created by the sender or receiver. Alice cannot decide by herself to send anonymous messages -- she must trust the infrastructure to provide protection, and others must use the same infrastructure."
"It's tempting to scale down the reputation system instead. That is, servers use only local information from their own transactions and trades... Rather than the global gossip system where the whole world learns from a server's first interaction, now each server has a chance to waste the time and resources of every other server (the "screw everyone once" attack)."

A very nice anonymity system, with a nice explanation of how to leverage dining cryptographers in a p2p setting.
The reason this paper is included in this section is for its use of hashcash to limit an adversary's ability to generate ids targetting a specific range offline. By requiring each node to search for collisions with timestamps in the lower bits of the collision source, old collision values cannot be used in the future, and significant computational resources are required to target specific id ranges.

Describes work extended from the original (1997) hashcash proposal, finding partial collisions in cryptographic functions as a method of imposing cost (in email). Similar to the join cost function in Herbivore. This is not the first paper to describe computational cost functions to prevent spam, for that, see Dwork and Naor's "Pricing vi Processing, Or Combatting Junk Mail" in Advances in Cryptology CRYPTO'92, Lecture Notes in Computer Science No 740, Springer, 1993, pp 139-147

A Lightweight Currency Paradigm for the P2P Resource Market
@misc{ turner03lightweight, author = "David A. Turner and Keith W. Ross", title = "A Lightweight Currency Paradigm for the {P2P} Resource Market", year = "2003", url = "citeseer.ist.psu.edu/turner03lightweight.html" }
Advocates a system and protocol for an 'ultra-free market economy' where any entity can issue currency and participants can exchange resources by exchanging their currencies. The currencies, as put forth, are administered through a third party.
While overall, there are some neat ideas here, there are also a lot of problems. By requiring third parties to keep track of trust, the trust/reputation requirements are only shifted to involve even more parties (and ones for which self-interest is very difficult to judge). And the possible proliferation of currencies requires that a broker class come forward so that money can be exchanged, but again, where do individuals store their trust/reputation for these brokers? The paper suggests another third-party that will store reputations (but how to trust these?). The opportunity for collusion and gaming of the system seem to be multiplied by all these layers, and self-interest doesn't seem to drive many of the roles that must be played. So, while the paper is bold for emphasizing a 'wild-west' monetary system, it doesn't address lawlessness issues and how to deal with the wide variety of exploits that could arise in such a system.
It does state a couple of correct principles: that of strong identity tied to self-chosen public keys, and that individuals are free to set their own prices for resources.
A Taxonomy of Rational Attacks

Wallach, A Taxonomy of Rational Attacks In Proc. of IPTPS, Ithaca, NY. February 2005", year = "2005", url = "citeseer.ist.psu.edu/nielson05taxonomy.html" }
A very good taxonomy of rational attacks (just as the title suggests), and a group of general solutions:
- eliminate rationality as a concern (out-of-band trust, partial centralization, or trusted software -- all largely non-p2p solutions)
- design genuine incentives (these are the simplest to implement and provide the best protection, but hard to devise)
- use artificial incentives carefully (prefer non-instantaneous maturation, use reputation, protect auditing infrastructure)
Points to a couple of other important papers, including Douceur's "Sybil Attack" observation that only centrally controlled IDs can prevent a malicious node from assuming many simultaneous identities*, and to the Tangler's document entanglement strategy.
\* this is only true if the central authority can never be tricked into handing out multiple IDs to one entity, or if it charges for this service (to limit multiple IDs by real-world economic factors).

Non-Transitive Connectivity and DHTs

Freedman and Karthik Lakshminarayanan and Sean Rhea and Ion Stoica", booltitle = "Proc. 2nd Workshop on Real, Large, Distributed Systems ({WORLDS 05})", address = "San Francisco, CA", month = Dec, year = 2005 }
Points out problems for DHTs with non-transitive connections (non-transitivity is common). The only ones that seem to be an immediate problem for Kademlia (at least as implemented in flud) are: 1) need to implement an 'unreachable' cache and 2) eliminate blind trust. (see question and response in p2p-hackers).
Security Considerations for Peer-to-Peer Distributed Hash Tables
@inproceedings{chord:security02, title = {Security Considerations for Peer-to-Peer Distributed Hash Tables}, author = {Emil Sit and Robert Morris}, booktitle = {Proceedings of the 1st International Workshop on Peer-to-Peer Systems (IPTPS)}, year = {2002}, month = {March}, address = {Cambridge, MA}, }
Nice overview of several known security issues in DHTs. Produced the following 6 guidelines: 1) define verifiable system invariants, and verify them; 2) allow the querier to observe lookup progress; 3) assign keys to nodes in a verifiable way; 4) be wary of server selection in routing; 5) cross-check routing tables using random queries; and 6) avoid single points of responsibility.
Outlined the following 9 attacks (many of which are not applicable to kademlia-style DHTs):
- unauthentic data: can be solved using cryptographic techniques, such as self-certifying path names (done in flud)
- incorrect lookup routing: not an issue in kademlia's recursive routing, as the source of the query is 'observing' all queries already. Suggests assigning keys to nodes in a verifiable way (done in flud).
- incorrect routing updates: kademlia's replacement strategy makes it difficult for a malicious node to suceeed. New routes are only added after the node verifies reachability (doing in flud).
- partitions: partitions are possible in kademlia, but can be healed by doing some random queries instead of strictly directed ones during lookup (see, for example, http://zgp.org/pipermail/p2p-hackers/2003-August/001348.html). Suggests using trust metrics with strong identity (done in flud).
- storage and retrieval attacks: Suggests implementing replication, which is core to kademlia (done in flud). Suggests consulting at least two replicas to make sure the data is good (doing in flud). Suggests using strong identities for nodes so that a node cannot 'choose' to become responsible for targetted data (done in flud).
- inconsistent behavior: somewhat handled in flud with the trust system (since the trust system is limited to a subset of all nodes -- mainly trading partners -- the trust system doesn't extend to all DHT nodes. All nodes close to a misbehaving node will monitor it and eventually reject it, but not if it deals honestly with close nodes and dishonestly with distant nodes... Replication and limiting nodeID choice help out here).
- overloading targetted nodes: DHTs alread handle this. But to be even better, suggests that node ID be assigned randomly (done in flud)
- rapid joins and leaves: this is mostly a problem for Chord-like DHTs. Kademlia does not need to move data around when nodes come and go, so it doesn't apply. Additionally, a core piece of the trust metric is availability. Nodes that come and go will gain little trust. Same issues as in #6 apply.
- unsolicited messages: this attack is possible, though extremely difficult due to reliance on http as a transport; in order to carry out the attack, the attacker must hijack a short-lived http session and inject its message before the true responder is able to do so. Therefore, the attacker must not only be lucky, but must be lucky presciently.
Improving Lookup Performance over a Widely-Deployed DHT
@inproceedings{conf/infocom/StutzbachR06, title = {Improving Lookup Performance Over a Widely-Deployed DHT.}, author = {Daniel Stutzbach and Reza Rejaie}, booktitle = {INFOCOM}, crossref = {conf/infocom/2006}, publisher = {IEEE}, url = {http://dblp.uni-trier.de/db/conf/infocom/infocom2006.html#StutzbachR06}, year = {2006}, description = {dblp}, ee = {http://dx.doi.org/10.1109/INFOCOM.2006.329}, date = {2007-07-18}, keywords = {dblp } }
Nice analysis of some optimizations to the Kademlia protocol for efficiency and consistency. Claims to pinpoint the best values for replication and parallelism when using Kademlia.

Miscellaneous Peer-to-Peer
Feasibility of a serverless distributed file system deployed on an existing set of desktop PCs

Took a series of measurements from nearly 65,000 desktop machines at Microsoft.
Transient failures are common, but permanent failures are rare. It is unlikely that even 1% of a large population of nodes all fail at during some short interval.
Describes (perhaps for the first time) convergent encryption.
Measured disk usage, content, and access rates. Measured machine uptime, downtime, lifetime, and correlation. Different tests were performed at different times, but most were performed over a period of several weeks.
Concluded that average disk usage is at 50-53%, and that removing duplicate files across systems reclaims 47% of used file space.
Experiences in Building and Operating ePOST, a Reliable Peer-to-Peer Application
@inproceedings{mislove-2006-epost, author = {Alan Mislove and Ansley Post and Andreas Haeberlen and Peter Druschel}, title = {Experiences in Building and Operating {ePOST}, a Reliable Peer-to-Peer Application}, booktitle = {Proceedings of EuroSys 2006}, location = {Leuven, Belgium}, month = {April}, year = {2006} }
Nice discussion of [unexpected] problems encountered after initially designing ePOST.
Uses a centralized entity (epost.org) to assing nodeIDs to discourage Sybil attacks (note that this centralized entity can be tricked into giving out multiple IDs to one entity, so it is not a complete solution).
Lesson 1: Discussed revealing statistics about network partitions and the need to deal with them. On the PlanetLab deployment, the overlay was partitioned 110 times in 3 months (more than once/day)! Usually, these partitions consisted of one large partition, and then one or more very small partitions (avg size 12.4 nodes). ePOST solutions to this problem are largely domain-specific.
Lesson 2: Tolerate partial network connectivity. Same topic here as Non-transitivity paper. Solutions presented are Pastry-specific, and somewhat complex implementation-wise (virtual links), (kademlia is already largely resilient).
Lesson 3: Ensure routing consistency in Pastry. Again, this topic is largely irrelevant to kademlia, and involves some hackish fixes, like adding a watchdog process to monitor the local ePOST instance, etc.
Lesson 4: Withstand large-scale failures. Failures can be correlated, and caused by homogeneity (both in software and in network geography). Solved by introducing more heterogeneity and by using a storage layer with sufficient redundancy to survive massive failures (up to 80%).
Had some good suggestions from experience, such as the observation that storing lots of small files in directories causes OS-level problems and that it may be better to build on top of a DB layer.
Erasure Coding
Design and Evaluation of a Low Density Generator Matrix (LDGM) Large Block FEC Codec
@misc{ roca03design, author = "V. Roca and Z. Khallouf and J. Laboure", title = "Design and evaluation of a low density generator matrix", text = "V. Roca, Z. Khallouf, and J. Laboure. Design and evaluation of a low density generator matrix (ldgm) large block fec codec. In Fifth International Workshop on Networked Group Communication (NGC'03), Munich, Germany, Sept. 2003.", year = "2003", url = "citeseer.ist.psu.edu/roca03design.html" }
A must-read if using LDPC/LDGM libs (as flud does). Discusses tradeoffs for choosing k and n, and graphs choice of left-degree (which determines, with seed, the matrix used for coding/decoding) over a wide range of choices for k.
The paper also spends significant time comparing these codecs to RSE, and discussing the inefficiency ratio (number of blocks > n needed to decode)
Since we'll be using a smaller k for flud, it appears that a left-degree of 6 is more optimal, though we need to do some more experiments, as k < 100 doesn't really appear to be shown (perhaps 5 is even better).
Impacts of Packet Scheduling and Packet Loss Distribution on FEC Performances: Observations and Recommendations
@inproceedings{1095944, author = {Christoph Neumann and Vincent Roca and Aur\&\#233;lien Francillon and David Furodet}, title = {Impacts of packet scheduling and packet loss distribution on FEC Performances: observations and recommendations}, booktitle = {CoNEXT'05: Proceedings of the 2005 ACM conference on Emerging network experiment and technology}, year = {2005}, isbn = {1-59593-197-X}, pages = {166--176}, location = {Toulouse, France}, doi = {http://doi.acm.org/10.1145/1095921.1095944}, publisher = {ACM Press}, address = {New York, NY, USA}, }
More in-depth analysis of different LDPC/LDGM strategies and impacts. Plots inefficiency ratio against p (probability of transitioning to loss state) and q (probability of transitioning out of loss state). Models 6 different transmission models.
Model 4 (send both source and parity packets randomly) best matches flud behavior. This model reacts best with LDGM Triangle.

"A significant conclusion from this analysis is that while there are indeed practical situations where Reed-Solomon coding clearly outperforms LPDC codes, there are also practical situations where LPDC codes outperform Reed-Solomon coding for all values of n."

The topology of covert conflict
@techreport{UCAM-CL-TR-637, url="http://www.cl.cam.ac.uk/TechReports/UCAM-CL-TR-637.pdf", author="S. Nagaraja and R. Anderson", title="The Topology of Covert Conflict", institution="University of Cambridge Computer Laboratory", number="UCAM-CL-TR-637", month="July", year="2005" }
Discusses scale-free networks and vertex-order attacks. Analyzes 3 classes of defense against such attacks, and shows that, of the 3, a clique-based defense is most effective. Very interesting analysis, building a 'bridge between network science and evolutionary game theory'.
Although it isn't immediately apparent that flud is scale-free per se, it is possible that some scale free properties will emerge as individual nodes choose storage partners at the storage layer. And although the DHT layer also seems to be non-scale-free, the network beneath the overlay certainly may be.
Defending the Sybil Attack in P2P Networks: Taxonomy, Challenges, and a Proposal for Self-Registration
@techreport{ url="http://dsn.tm.uni-karlsruhe.de/medien/publication-confs/dinger_dasp2p06_sybil.pdf", author="Jochen Dinger and Hannes Hartenstein", title="Defending the Sybil Attack in P2P Networks: Taxonomy, Challenges, and a Proposal for Self-Registration", institution="Institut fur Telematik, Universitat Karsruhe (TH), Germany", booktitle="DAS-P2P 2006", month="April", year="2006 }
Good overview of the Sybil attack in p2p systems, proposed solutions and stopgaps.
While this point is not in the paper, it is generally true that smaller networks are easiest to mount sybil attacks against. But small networks may not be as valuable of targets as large networks. And large networks are, by their largeness, more difficult to perform a sybil attack against. This is especially true if the network performs well under Byzantine conditions -- the attacker's work in generated sybil nodes is proportional to the size of the network.

I'm calling about the Nov. 15 SpeakOut in the paper about school officials. I agree totally with what the person said about Veterans Day. My grandfather was killed and let me tell you something, if it weren't for the veterans, there wouldn't be a Martin Luther King Day. They dismiss school on his birthday because he was black and they don't want black people crying "racism," but all the white people's families sent their fathers or brothers or grandfathers and they died. They don't care nowadays. Now days it's just to please the black and that's why we are out of school on Martin Luther King Day. Now, SpeakOut, you're supposed to print as long as you don't use foul language and stuff.
If you want pigeons, call 683-4308.
Hats off to the person who called about the lawyer being arrested and sentenced to 40 months on drugs. Of course there is a problem with the justice system. There always has been and always will be. If you've got the pull, the right job, name or money, you can usually get yourself out of them problems and you make the point brilliantly. Many times I've seen a lot of people in town and in the area go up for a lot longer than that. And this involved the feds, too. I certainly agree with you. We have to wonder, too, I hear we won't see any further indictments. Of course you won't see any further indictments because that would go too far into the alleged drug ring in Southeast Missouri, wouldn't it?
Just to get one fact straight about the local lawyer, he pled guilty. There was no trial. He admitted to the facts and admitted to distributing methamphetamine.
You people who trust the Red Cross so much, I hope you're happy. All the money we donated and raised for the World Trade Center, two people have lost their husbands and didn't get any of that money. They gave one lady a grant to pay her rent for three months and they hadn't given her any money or any help. They took over $650 million and they only spread out $6 million, they claim. These people aren't getting that money. It was supposed to be for the World Trade victims. I won't be donating to them any more after what happened. If I give any more money, I'll give it myself.
Why didn't you print what I called in last week about two organizations that collect money? It was true because it was on the news. Could it be that you agree with the way they give away a lot of the donations that were meant for the victims of the terrorist attacks to the defense of the terrorists who were arrested that day? Or do you agree with the organization that caved in to the homosexuals who give insurance and other benefits to their significant others? Who should we give money to? Them or the kids at Christmas time? Which one do you agree with, Mike. We'd like to know.
In answer to the Nov. 15 SpeakOut "No hero here," Bill Clinton was not impeached for having sex in the Oval Office. He was impeached for lying under oath, obstructing justice and denying a woman her day in court. Can you not understand this?

After U.S. Election, Canada Taking Stock of Winners and Losers
By WSJ Canada
After Barack Obama's reelection last night, Washington and Wall Street will be fleshing out winners and losers. Some are obvious: The U.S. financial-services sector, for example, backed one of its own–former private-equity executive and Republican challenger Mitt Romney. Forget about a Republican White House rolling back some of the new regulations circumscribing the industry in the wake of the financial crisis.
In Canada, there are winners and losers, too, from election night down south, though perhaps not as clear cut. Here's the early morning-after tabulation:
Canadian exporters. A ballot initiative failed in Michigan that would have put to a referendum whether to go ahead with a second bridge to Canada near Detroit. Canada had already committed to funding much of the new bridge, something that Canadian exporters—and Prime Minister Stephen Harper—have pushed hard for.
Investors in long Canadian bonds. Those instruments rallied this morning on expectation that monetary policy in the U.S. will continue to favor easy money.
Pot growers in British Columbia? Ballot initiatives in next-door Washington State and Colorado legalized pot for recreational use. Those wins set up a showdown with federal authorities—whose ban on pot still stands and who patrol the U.S.-Canadian border. Still, the wins may hearten B.C. growers, increasingly the supplier of choice for the U.S. West. (That's not good news of course for Canadian authorities, including the Royal Canadian Mounted Police, who have tried with their American counterparts to slow down the cross border trade in the stuff.)
TransCanada The Calgary-based pipeline company still hopes to build its Keystone XL pipeline from Alberta to the Gulf of Mexico. After the Obama administration rejected a cross-border permit for the line earlier this year on environmental grounds, the White House promised to review it again without prejudice after the election. Canadian executives (including at TransCanada) and Canadian government officials all say they believe the line would eventually get the nod no matter who won the White House. But Mr. Romney frequently said approval would be one of his first priorities.
Toronto-Dominion Bank and Bank of Montreal: These two banks have big operations in the U.S.–and ambitions for heady growth south of the border. But they too have labored under new regulations that have come into place in the U.S. since the financial crisis. Mr. Romney offered hope that some of that new red tape may be lifted.
