Traps to avoid when dealing with time critical issues

Traps to avoid when dealing with time critical issues

All Developers/Operations team members know the pressure and stress of finding and fixing a critical issue in their code or infrastructure. When dealing with issues, they often enter panic mode to try and get the issue resolved as soon as possible. While this can yield positive results, it can also lead to mistakes. Two frequent traps we fall into when in panic mode are: The quick fix - you cut some corners so that everything starts working again, promising to fix those tests or perform that extra step laterMaking too many changes - you implement several fixes at once, then have to figure out what change fixed the issue

Multithreading and Multiprocessing

Multithreading and Multiprocessing

Many programming languages allow for multithreading and multiprocessing as a means of parallel execution of code. This form of programming allows for tasks to be split into groups of tasks that can be executed concurrently. This can lead to faster execution times for tasks that are not blocked by other operations. There are however several advantages and disadvantages to this form of programming.Multithreading and Multiprocessing can allow for better performance when executing certain operations. There are many different forms of multithreading and multiprocessing implementations, it is important to know the limitations of each implementation and to consider such things as: number of processors (or threads) that are available when the code is runningthe duration and number of tasks that are being executed

Why is technical debt becoming increasingly important?

Why is technical debt becoming increasingly important?

Technical debt is very similar to financial debt in that software developer’s use when talking about the extra costs associated with changing a system’s codebase and architecture. It can involve debugging code or revising requirements for a weak design or aging third-party library. Technical debt is significant to most organizations using software to run their business as it costs time as well as money. Gartner estimated that the sum amount of technical debt worldwide reached $1 trillion in 2015 and could double its figure in the coming years. With this in mind, let’s look at what technical debt is and a few reasons why technical debt is becoming increasingly important.
