Some memory leaks are straightforward to detect. A process allocates memory, forgets to free it, and grows until something breaks. This was not that kind of leak. This is the story of how Canonical Support helped a global retail organization trace the cause for an unusual memory leak originating in PID 1, the very first process started by the kernel during the system boot sequence. The memory footprint was 10 times higher than expected.

Staring at an empty test folder is often the hardest part of end-to-end testing. To help, here are ten common end-to-end test ideas you can build with Playwright, with code examples for two of the most requested scenarios: login and form submission.

Hyperping· Uptime monitoring Know before your customers do. Monitor from 18 regions and route alerts by phone, SMS, Slack or email. Start free Playwright and Puppeteer solve the same problem, driving a real browser from Node.js, and Playwright was started by engineers who previously built Puppeteer. That shared ancestry makes the two APIs look similar at first glance, which is exactly why the differences below catch people off guard.

Managing cloud, AI, and SaaS costs means answering a steady stream of questions from finance, leadership, and engineering teams. What changed? Which team owns the spend? Was an increase expected? Are we still on track against the budget? When each answer requires moving between dashboards, filtering cost data by team or service, or manually correlating billing data with observability data, it can slow down investigations while costs continue to rise.

It is 9:02 on Monday morning. Within minutes, hundreds of employees hit the logon button at once, and the helpdesk queue fills with the same three words: Citrix is slow. The team scrambles. Is it the Delivery Controller? Active Directory? The profile server? Storage? Without the right Citrix monitoring tools, that question can take hours to answer, and every minute is a roomful of people who cannot work.

It is 2 a.m. The pager goes off. Checkout is down, customers are dropping, and you have five dashboards open across four tools that do not agree. One says the application is fine. Another says latency is climbing. None tells you why. This is the moment that decides whether you have the right application performance monitoring tool. Modern applications run across containers, cloud services, APIs, and infrastructure spanning on-premises and multiple clouds.

‍ For more than a decade, Infrastructure as Code (IaC) has transformed how engineering organizations build and operate systems. Infrastructure became programmable, provisioning became repeatable, and configuration became version-controlled. Teams gained the ability to automate environment creation, enforce policy consistently, and scale infrastructure operations far beyond what manual processes could support.

On July 16, 2026, AWS experienced a disruption in its CloudFront service, which affected a large number of websites and applications. The outage was caused by a configuration loading failure in CloudFront's VPC Origins feature. This was AWS's most widely-felt outage after last year's outage on October 20th, which caused widespread damage.
