Unless a result relies on a specific hardware trick, such as a proprietary accelerator or modified instruction set, it is possible to reproduce the results of one group by a different one. Unlike the physicists we don't have to build a second Hadron Collider to verify the result of the first. We have millions of similar, and sometimes identical, devices, on which to reproduce our results. All that is required is the will to do so. [ABSTRACT FROM AUTHOR]

The problem with software structure is people don't really learn it until they really need it, and your homework assignments will have to force them to look closely at how they are solving problems, not only through algorithms but through structure. [ABSTRACT FROM AUTHOR]

Since the systems have a common parent, they probably work in the same technical domain, and therefore the features and fixes that are going to be added are probably similar. KV happens to have an example case at hand: two operating systems that diverged before they added SMP (symmetric multiprocessing) support. When an operating system adds SMP to an existing kernel, the first thing we think of is locks, those handy-dandy little performance killers that we've all been sprinkling around our code since the end of Dennard scaling.

On keeping a laboratory notebook. [ABSTRACT FROM AUTHOR]

One of the easiest tests to determine if you are at risk is to look hard at what you do every day and see if you, yourself, could code yourself out of a job. Programming involves a lot of rote work: templating, boilerplate, and the like. If you can see a way to write a system to replace yourself, either do it, don't tell your bosses, and collect your salary while reading novels in your cubicle, or look for something more challenging to work on.

An answer is provided to a question concerning advice for computer coding professionals working remotely from home.

The article provides an answer to a question regarding computer coding, particularly restrictions surrounding tabs and spaces in source code.

The article discusses sockets API (application programming interface). The author examines the conditions present when sockets API was developed in 1982 at the University of California Berkeley, as well as exploring the manner in which such conditions informed the way networking code has been written. Additionally, the author describes developers' attempts to work around inherent limitations built into sockets API. Other topics include the future of sockets given the changes occurring in computer networks.

The article presents advice and an answer to the question of how to address challenges in computer programming through the navigation of patches and source code archived within a project repository.

The article presents questions and answers related to computer programming including the importance of using warning messages when writing software code and the process of reviewing software from a potential company acquisition in terms of the intellectual property rights associated with that software.

An answer to a question about computer coding patents is presented.

The article discusses computer programming, examining the complexity of the computer code required by increasingly complex systems. The tools used to understand the complex systems have not grown at the same rate, size, or scope as the systems in question. Topics of discussion include Moore's law regarding the power of computers, code from outside sources integrated by software teams, and complex interactions between systems. Also discussed are systems calls provided to user programs by an operating system (OS) kernel.

This article presents views of various executives related to the computer industry, on the Association for Computing Machinery (ACM). Kevin M. Schofield, general manager at Microsoft Research, states that ACM is now embarking on its second 50 years of existence, and is facing the imperative of remaking itself for the 21st century. It has begun this process by embracing the move to put its information assets online through the Digital Library. ACM needs to decide whether it is primarily a membership-based professional society or a public advocacy organization. David S. Wise, professor at the Computer Science Department of the Indiana University, remarked that ACM serves primarily as a publishing cooperative. Colleagues world-wide seek ACM list for its excellent collection of journal and conference productions in print, on line, and in person. But, as a scientific and educational organization, ACM also serves laypeople and governments internationally, representing what information technology is and what it can be. Both as a society and as a publisher with a large database, ACM is uniquely positioned to restrain international intellectual property law via local policy groups.

The article presents questions and answers related to computer science. Topics include the costs or benefits of creating a new wireless Internet transport protocol for a business network rather than relying on existing Internet protocols such as transmission control protocol (TCP) or user datagram protocol (UDP); and a discussion of how to test software.

The author discusses the challenges of building distributed computing systems. He observes that whereas non-distributed systems tend to fail in predictable ways that often have straightforward remedies, systems with two or more clients can be plagued by unpredictable problems whose solutions aren't obvious. Scaling up the number of users can create issues, he notes, as can upgrading to faster network hardware. He emphasizes a good record of network errors is vitally important to debugging a distributed system.
