If you have a public-facing web application, the odds are you should probably be thinking about load testing. Any tester can (and should) add load testing to their repertoire. Functional tests are often carried out with a single user’s experience of your application in mind, but what happens when hundreds or thousands of users are on your site at the same time?

Dynatrace news. In recent years, the volume of reported security vulnerabilities in enterprise software has increased exponentially. At the same time, cloud-native technologies and open-source software have introduced a new level of speed and complexity. While DevSecOps teams focus on detecting and remediating security vulnerabilities as early in the release pipeline as possible, developers are trying to keep pace with the high number of security alerts.

For USENIX LISA2021 I gave a 40 minute deep dive talk on BPF internals for Linux, focusing on observability tracing tools. Since there are already BPF internals references online (listed in this post) I used the opportunity to create some new content, showing how bpftrace instrumentation works from user space down to machine code. I break it down to all the small components involved, where you'll find it's actually quite easy.

Query optimization is an expensive process that needs to explore multiple alternative ways to execute the query. The query optimization problem is NP-hard , and the number of possible plans grows exponentially with the query’s complexity. For example, a typical TPC-H query may have up to several thousand possible join orders, 2–3 algorithms per join, a couple of access methods per table, some filter/aggregate pushdown alternatives, etc.

Most software development organizations now follow agile scrum methodology. In most cases, they divide their work in sprints – a repeatable fixed time-box during which all tasks for a deliverable are planned and executed. After each sprint, the target is to complete as many planned tasks as possible and come up with a deliverable. A user story is the smallest unit of work in an agile framework.

Most databases should make use of foreign keys to enforce referential integrity (RI) wherever possible. However, there is more to this decision than simply deciding to use FK constraints and creating them. There are a number of considerations to address to ensure your database works as smoothly as possible. This article covers one such consideration that does not receive much publicity: To minimize blocking , you should think carefully about the indexes used to enforce uniqueness on the parent s

A few years back, I gave my friend a keyword to search on Google and asked him to open the third link that pops up in the results. After five minutes of confusion, I realized we are not talking about the same website and even though the keyword was the same, the results appeared in a different order. This urged me to check out the support page of Google and find out this written on it, “ When you search on Google, your results are customized to your current region. ” Digging more into these new

Home assistants and smart displays are being sold in record numbers, but they are built wrong. They are designed with one person in mind: the owner. These technologies need to fit into the communal spaces where they are placed, like homes and offices. If they don’t fit, they will be unplugged and put away due to lack of trust. The problems are subtle at first.

In business, technology and general, the word “domain” appears frequently and with many different meanings in various contexts. This gets tricky at times when collaborating with different companies or communities that use different definitions. The problem in general is that when we use generic and fuzzy words like domain we make assumptions that put the emphasis on the listener to correctly determine the context and choose the right meaning.
