In 2007, Pat Helland published “Life Beyond Distributed Transactions: An Apostate’s Opinion,” in which he conducts a thought experiment on how to design a distributed database that can scale almost infinitely. While the paper explicitly addresses distributed database design, I'll show that the ideas are far more widely applicable, particularly in scaling stateful applications. In particular, how we implemented some of the ideas from the paper in our distributed stream processor Wallaroo.

Adrian Cockcroft on Communicating Sequential Processes (http://spinroot.com/courses/summer/Papers/hoare_1978.pdf)
Paul Borrill on Lamport’s unfinished revolution.
This talk reviews Lamport’s seminal 1978 paper on Time, Clocks and the Ordering of Events, the 2nd most cited paper in all of computer science.
Almost all software engineers claim to have read it. Many who haven’t read it, use (and basically understand) the fundamental idea of logical clocks, and their progeny (vector clocks, matrix clocks, etc.). More than a few understand the current state of the art: dotted version vectors and bounded version vectors. Paradoxically, almost everyone misse…
Lukasz Jagiello on “pASSWORD tYPOS and How to Correct Them Securely” (https://www.cs.cornell.edu/~rahul/papers/pwtypos.pdf)
Lukasz tells us: “typo-tolerant password authentication for arbitrary user-selected passwords” sounds like a really bad security joke but if we combine that with metrics where almost 10% of failed login attempts fail due to a handful of simple, easily correctable typos, such as capitalization errors. Authors proves it is possible to improve user experience with really low impact on security.
I really enjoy this paper because it’s not a standard security approach and in many places it’s a reasonable tradeoff between security and UX.
Lukasz Jagiello is an operations engineer at Wikia where he is hard working on saying NO. Between NO…
Tyler McMullen on Similarity Estimation Techniques from Rounding Algorithms
Tyler's Bio: Tyler McMullen is CTO at Fastly, where he’s responsible for the system architecture and leads the company’s technology vision.

Joel VanderWerf on The Krohn-Rhodes Theorem and Distributed Computing ( http://www.ams.org/journals/tran/1965-116-00/S0002-9947-1965-0188316-1/S0002-9947-1965-0188316-1.pdf )
The Krohn-Rhodes Theorem of 1962 surprised the math world by building arbitrary finite semigroups, and hence arbitrary finite state machines, out of flip-flops (registers with reset operations) and groups (permutations). The construction uses the wreath product, a coordinate system with unidirectional data flow among the factors, like addition with carry. How many group factors are needed? We don't know if this complexity question is decidable, after a half century of work. However, the effort …
Gilbert Bernstein on Marching Cubes (http://www.eecs.berkeley.edu/~jrs/meshpapers/LorensenCline.pdf )
Marching Cubes is one of the most important geometry algorithms for 3D volume visualization, 3D scanning/reconstruction, etc. It has the distinction of being the most cited graphics paper ever. And it's also definitely not the best algorithm you could implement for the problem it solves. Intriguing?

Jeff Carpenter presents Design Principles Behind Smalltalk by Daniel H. H. Ingalls. Jeff tells us: This a paper I love because it frames programming language design as a means to "provide computer support for the creative spirit in everyone." The paper describes the design principles the Learning Research Group at PARC discovered as they evolved the design of the Smalltalk language.
Stephen Tu presents: "Random features for large-scale kernel machines" (http://www.eecs.berkeley.edu/~brecht/papers/07.rah.rec.nips.pdf) by Ali Rahimi and Ben Recht
Kernel methods in machine learning are a popular tool used to express richer function classes. These methods work via access to a kernel function, which can be thought of as a measure of similarity between two vectors. The standard method of optimization via kernels requires solving a program with decision variable the size of the number of data points. As dataset sizes grow, this becomes prohibitive.
This paper addresses this issue in a surprisingly practical way. Specifically, the authors show that by using a multiple of d random projections based on the Fouri…

Devon O'Dell on "Nonblocking Algorithms and Scalable Multicore Pro…
From Nathan: "This is one in a long line of papers advocating for a loosely-coupled, service-oriented operating system architecture, an argument that extends back to the dawn of systems research. Alternative OSs like microkernels have long been considered more stable and easier to reason about by the systems community, but the performance overhead that comes with running them means typically our OSs still resemble the ones from the '60s. The authors have spun the "it will be too slow" argument on its head by extrapolating hardware trends and adopting terminology from the distributed systems community, and end up making a compelling case for their design not only being the _only_ path forward,…
Matt Adereth on "The Mode Tree: A Tool for Visualization of Nonparametric Density Features"(http://adereth.github.io/oneoff/Mode%20Trees.pdf). From Matt: "We often look at summaries of univariate data using basic descriptive statistics like mean and standard deviation and visualizations like histograms and box plots. The Mode Tree is a powerful alternative visualization that reveals important details about our distributions that none of the standard approaches can show.
I particularly like this paper because it was really the by-product of some interesting algorithmic work in Computational Statistics. A lot of the techniques in this area are pretty math heavy and inaccessible, so I appreciated that they dedicated a paper to making a visualizat…

Peter Bailis presents the "Managing Update Conflicts in Bayou, A Weakly Connected Replicated Storage System" paper by Doug Terry, Marvin Theimer, Karin Petersen, Alan J. Demers, Mike J. Spreitzer, and Carl H. Hauser in SOSP 1995. http://db.cs.berkeley.edu/cs286/papers/bayou-sosp1995.pdf
Peter tells us: "A perennial challenge in managing shared, mutable state in distributed systems is the ability to permit concurrent writes while maintaining some degree of application "correctness." Bayou is an excellent and early example of an "optimistic" strategy for handling the concurrent update problem. Many of the techniques in Bayou---such as dependency tracking, application-specific merge procedures, and log shipping---are increasingly popular, can be found in systems like Dynamo, and …
Leif tells us: " My favorite problems are always those with the highest ratio of difficulty in solving to difficulty in stating. The lowest common ancestor problem exemplifies this. It was first stated in 1973, and can be described to anyone in two sentences, or with one sentence and a picture. But it took 11 years before an optimal solution was discovered, and another 16 before an understandable and implementable solution with the same bounds was presented, in this paper, The LCA Problem Revisited<…
Kyle Kingsbury presents the On the attraction between two perfectly conducting plates paper.
In Kyle's words: "It's a very short physics paper--a sidenote, really, to work he considered much more important. Sixty years later, though, we consider this sidenote his defining work--it gave rise to one of the weirdest physics phenomena ever, and has only gotten *more* confusing since the original proof. There's a really interesting history behind it that reveals some of the sociology of academia. Plus it's just fucking fascinating physics.
It also doesn't require any math beyond, say, high school calculus, but illustrates what a rigorous formal argument looks like--and I'm well-prepared to teach the math and concepts to an audience without any mathematical expertise. I think it…

We hope that you'll read the paper before the Meetup (and if you don't, no worries). If you have any questions, thoughts, or related information, please visit our *github-thread* on the matter: https://github.com/papers-we-love/…
