You must have some trust if you want to get anything done.
In his novel The Diamond Age,7 author Neal Stephenson describes a constructed society (called a phyle) based on extreme trust in one’s fellow members. Part of the membership requirements is that, from time to time, each member is called upon to undertake certain tasks to reinforce that trust. For example, a phyle member might be told to go to a particular location at the top of a cliff at a specific time, where he will find bungee cords with ankle harnesses attached. The other ends of the cords trail off into the bushes. At the appointed time he is to fasten the harnesses to his ankles and jump off the cliff. He has to trust that the unseen fellow phyle member who was assigned the job of securing the other end of the bungee to a stout tree actually did his job; otherwise, he will plummet to his death. A third member secretly watches to make sure the first two don’t communicate in any way, relying only on trust to keep tragedy at bay.

To millions of game geeks, the position of QA (quality assurance) tester at Electronic Arts must seem like a dream job. But from the company’s perspective, the overhead associated with QA can look downright frightening, particularly in an era of massively multiplayer games.

High-level DSLs for low-level programming
BO JOEL SVENSSON, INDIANA UNIVERSITY

DSLs (domain-specific languages) make programs shorter and easier to write. They can be stand-alone—for example, LaTeX, Makefiles, and SQL—or they can be embedded in a host language. You might think that DSLs embedded in high-level languages would be abstract or mathematically oriented, far from the nitty-gritty of low-level programming. This is not the case. This article demonstrates how high-level EDSLs (embedded DSLs) really can ease low-level programming. There is no contradiction.

If you see something, say something.
In February Apple revealed and fixed an SSL (Secure Sockets Layer) vulnerability that had gone undiscovered since the release of iOS 6.0 in September 2012. It left users vulnerable to man-in-the-middle attacks thanks to a short circuit in the SSL/TLS (Transport Layer Security) handshake algorithm introduced by the duplication of agoto statement. Since the discovery of this very serious bug, many people have written about potential causes. A close inspection of the code, however, reveals not only how a unit test could have been written to catch the bug, but also how to refactor the existing code to make the algorithm testable—as well as more clues to the nature of the error and the environment that produced it.

Looking at embedded DSLs
ANDY GILL, UNIVERSITY OF KANSAS
There are many ways to give instructions to a computer: an electrical engineer might write a MATLAB program; a database administrator might write an SQL script; a hardware engineer might write in Verilog; and an accountant might write a spreadsheet with embedded formulas. Aside from the difference in language used in each of these examples, there is an important difference in form andidiom. Each uses a language customized to the job at hand, and each builds computational requests in a form both familiar and productive for programmers (although accountants may not think of themselves as programmers). In short, each of these examples uses a DSL (domain-specific language).

How good security at the NSA could have stopped him
Edward Snowden, while an NSA (National Security Agency) contractor at Booz Allen Hamilton in Hawaii, copied up to 1.7 million top-secret and above documents, smuggling copies on a thumb drive out of the secure facility in which he worked, and later released many to the press. This has altered the relationship of the U.S. government with the American people, as well as with other countries. This article examines the computer security aspects of how the NSA could have prevented this, perhaps the most damaging breach of secrets in U.S. history. The accompanying sidebar looks at the Constitutional, legal, and moral issues.
“Mostly functional” programming does not work.
There is a trend in the software industry to sell “mostly functional” programming as the silver bullet for solving problems developers face with concurrency, parallelism (manycore), and, of course, Big Data. Contemporary imperative languages could continue the ongoing trend, embrace closures, and try to limit mutation and other side effects. Unfortunately, just as “mostly secure” does not work, “mostly functional” does not work either. Instead, developers should seriously consider a completely fundamentalist option as well: embrace pure lazy functional programming with all effects explicitly surfaced in the type system using monads.

How can one make reasonable packages based on open-source software when most open-source projects simply advise you to take the latest bits on GitHub or SourceForge? We could fork the code, as GitHub encourages us to do, and then make our own releases, but that puts the release-engineering work that we would expect from the project onto us.

Stronger properties for low-latency geo-replicated storage
WYATT LLOYD, FACEBOOK; MICHAEL J. FREEDMAN, PRINCETON UNIVERSITY; MICHAEL KAMINSKY, INTEL LABS; DAVID G. ANDERSEN, CARNEGIE MELLON UNIVERSITY
Geo-replicated storage provides copies of the same data at multiple, geographically distinct locations. Facebook, for example, geo-replicates its data (profiles, friends lists, likes, etc.) to data centers on the east and west coasts of the United States, and in Europe. In each data center, a tier of separate Web servers accepts browser requests and then handles those requests by reading and writing data from the storage system

OpenSSL must die, for it will never get any better.
The OpenSSL software package is around 300,000 lines of code, which means there are probably around 299 bugs still there, now that the Heartbleed bug — which allowed pretty much anybody to retrieve internal state to which they should normally not have access — has been fixed.
That’s really all you need to know, but you also know that won’t stop me, right?
