Teaching rigorous distributed systems with efficient model checking Michael et al., Consider the lab exercise to implement Paxos. Luckily, code that is readily model checkable usually corresponds to the kind of code we want students to write — code that is as simple as possible with respect to its state graph.

Application performance monitoring (APM) is the practice of tracking key software application performance metrics using monitoring software and telemetry data. Causes can run the gamut — from coding errors to database slowdowns to hosting or network performance issues. Faster and higher-quality software releases.

Does your traffic increase come with updated code changes that change the queries? In fact, the most common cause of massive CPU increase that I’ve seen isn’t traffic increase; it’s code changes that introduced inefficient revisions to existing queries or new queries. Do these queries use more caches?

The distribution operation was built on efficiencies: fill delivery trucks to a minimum of 80% capacity and deliver products to customers on routes optimized for time and energy consumption. Distribution is about efficiency, because efficiency translates into price. These led to bad decision-making about the software.

Regression testing comprises re-running the test cases of already stable features and finding out if the new code changes attributed to the new release led to any negative impacts on the existing functionalities. Regression checks should start as soon as a new build is released for testing and should be repeated for every new code build.

I've worked with quite a few companies for which long-lived software assets remain critical to day-to-day operations, ranging from 20-year-old ERP systems to custom software products that first processed a transaction way back in the 1960s. Several things stand out about these initiatives.

Anyone who cares to download and fork the code can do so. " The eventual Blink fork was precipitated by an insurmountable difficulty in doing precisely what Apple suggested to Congress: contributing code upstream to WebKit to enable new features. It's worth assessing these claims from most easily falsified to most contested.

Pre-publication gates were valuable when better answers weren't available, but commentators should update their priors to account for hardware and software progress of the past 13 years.

Platforms are conceptually popular with investors: in theory, a platform makes the mundane portions of a business efficient, scalable and adaptable, allowing a company to release the creative talents of its people to pursue growth and innovation. Employees will see replatforming as an exercise in re-creating software.

We developed a friendly competition to break one another’s code. We are a bit wiser (you could take that as older) now and we don’t wait until 5 o’clock but we still try everything we can think of to exercise the code.

Sometimes it is divestiture or separation: sprawling firms that serve different buyers or markets don't achieve much in the way of operating efficiency, and a "conglomerate discount" priced into their equity means there is value that can be released by dividing a firm into multiple businesses. IT is at the center of deal synergy.

For example, in the Java world we can measure all kinds of attributes of code: overcomplicated expressions, wasteful use of resources, ghost code, duplicate code, complexity, and so forth. Good in the sense that code quality doesn’t need to be taken for granted, because we can measure attributes of the asset we’re creating.

A software application is not a collection of features that create business value. Some software requirements have a direct business impact. Thinking about "returns" is also more appropriate than "value" for capital deployment decisions, which is what software development really is. This isn't semantics.

In software, reacting to unforeseen circumstances in real-time is not possible. We have to specify with great precision in code exactly what our business rules are, and the computer will apply them exactly as we tell it to. In the software system, we need to decide the business transaction boundaries aka DDD Aggregates.
