‘ Load Average ‘ is an age-old metric reported in various operating systems. It’s often assumed as a metric to indicate the CPU demand only. However, that is not the case. ‘Load Average’ not only indicates CPU demand, but also the I/O demand (i.e., network read/write, file read/write, disk read/write). To prove this theory, we conducted this simple case study.
This is a guest post by Paddy Byers , Co-founder and CTO at Ably , a realtime data delivery platform. You can view the original article on Ably's blog. Users need to know that they can depend on the service that is provided to them.

Optimizing Video For Size And Quality. Optimizing Video For Size And Quality. Doug Sillars. 2021-02-15T15:00:00+00:00. 2021-02-15T15:34:02+00:00. Over the last few years, more and more projects are using video as an integral part of the application. This is a great direction, as videos are more engaging than still photos ( videos can double conversion rate and increase time spent on site ), and as such, can really draw customers to explore details about products and services.
Many mobile development and testing teams agree that it’s inaccurate to think of mobile applications as the same software running on a smaller device. Indeed, mobile application testing services differ greatly from any other project type. Here’s how we see the unique traits of mobile software testing. User Expectations. Mobile software is called mobile for a reason: these applications are expected to work on the go, anywhere, and at any time.

The world isn’t new to the mobile-first approach. Call it convenience or anything else — people are consuming content on their mobile phones more than their desktops and this will only increase in the near future. According to Statista , at least 50% of global online traffic is driven by mobile users. We were going through Adobe Retail Shopping Insights (2020) and found out that more than 42% of consumers have done their holiday shopping via smartphones.
I’m a huge fan of automation when the scenario allows for it. Maybe you need to keep track of guest information when they RSVP to your event, or maybe you need to monitor and react to feeds of data. These are two of many possible scenarios where you probably wouldn’t want to do things manually. There are quite a few tools that are designed to automate your life.
Oftentimes, when we write a stored procedure, we want it to behave in different ways based on user input. Let's look at the following example: CREATE PROCEDURE. Sales. GetOrders. ( @CustomerID AS INT = NULL , @SortOrder AS SYSNAME = N'OrderDate'. ) AS. SELECT TOP ( 10 ) SalesOrderID = SalesOrders. SalesOrderID , OrderDate = CAST ( SalesOrders.

I’m a huge Raspberry Pi advocate and own more of them than any single person should own. They are cheap, moderately powerful, and are useful for quite a few circumstances. In a previous tutorial titled, Emulate Classic Video Games On A Raspberry Pi Zero With RetroPie , I demonstrated how to repurpose an old Raspberry Pi Zero to be a gaming console about the size of an Amazon Fire Stick.

Mobile applications these days have become imperative for businesses. But mobile applications are not just another version of desktop applications. Mobile applications are as much different from desktop applications as mobile devices are different from desktop machines. Mobile applications, therefore, need to be built and tested with this difference in consideration.

When you think of developing a web application with modern features like real-time notifications, or advanced search options, two backend frameworks come to mind- Laravel and Symfony. Both have the ability to offer tools to help create scalable apps. But, if you are confused over which one to pick, here is a comprehensive take on the similarities and differences between Laravel and Symfony.
Performance budgets are one of those ideas that everyone gets behind conceptually, but then are challenged to put into practice – and for very good reason. Web pages are unbelievably complex, and there are hundreds of different metrics available to track. If you're just getting started with performance budgets – or if you've been using them for a while and want to validate your work – this post is for you.
The world of automation testing is rapidly evolving and we need to keep up with the pace. It’s no rocket science that the demand for automation testing is massive — according to Markets & Markets , the automation testing market size is projected to grow from $12.6B to $28.8B by 2024, globally. For businesses to be more agile and work with an unmatchable speed, cloud testing is crucial.
Near the end of January I was pointed to a twitter thread where a Windows user with a powerful machine was hitting random hangs in explorer. Lots of unscientific theories were being proposed. I don’t generally do random analysis of strangers’ performance problems but the case sounded interesting so I thought I’d take a look. Freya shared an ETW trace of what was happening on her machine and I took a look using Windows Performance Analyzer (WPA).
