Wine testing.browser testing.what's the difference? In the earlier days of web development, executing cross-browser testing used to be very easy. There used to be only a few limited browsers, each browser had limited versions in usage, and most importantly, there were not so many different mobile screen sizes to worry about. But time has turned upside-down, now there are multiple devices to check on, there are many different browsers available on the market that are used by a considerable number
PostgreSQL popularity is skyrocketing in the enterprise space. As this open source database continues to pull new users from expensive commercial database management systems like Oracle, DB2 and SQL Server, organizations are adopting new approaches and evolving their own to maintain the exceptional performance of their SQL deployments. We recently attended the PostgresConf event in San Jose to hear from the most active PostgreSQL user base on their database management strategies.
Have you ever gone to a public swimming pool and noticed a sign stating the maximum occupancy limit? Those limits were put in place to ensure public safety. APIs use a similar criterion, called a "rate limit," to ensure the safety of the API’s consumers and the API itself.

My good friend Aaron Bertrand inspired me to write this article. He reminded me of how sometimes we take things for granted when they seem obvious to us and don't always bother checking the full story behind them. The relevance to T-SQL is that sometimes we assume that we know everything there is to know about certain T-SQL features, and don't always bother checking the documentation to see if there's more to them.

Computers in the 90s. Ably recently had the pleasure of delivering real-time scoring and commentary updates to fans of the Laver Cup tennis championship, on behalf of Tennis Australia, for the third year in a row. During the event, I saw that Google embeds live score updates within search results, which is pretty nifty. It seems this first appeared in results sometime in 2016 and received an update for the.
Nodejs is one such javascript framework that allows you to build eCommerce websites. This article covers the options to build a node eCommerce app. The post How to Build an eCommerce Web Application using Node.js? appeared first on Insights on Latest Software Technologies - Simform Blog.
Some versions of HammerDB (e.g. 3.2) may induce imbalanced NUMA utilization with SQL Server. This can easily be observed with Resource monitor. When NUMA imbalance occurs one of the NUMA nodes will show much larger utilization than the other. E.g. Imbalanced NUMA usage by SQL Server. The cause and fix is well documented on this blog. In short HammerDB issues a short lived connection, for every persistent connection.
Learning a unified embedding for visual search at Pinterest Zhai et al., KDD’19. Last time out we looked at some great lessons from Airbnb as they introduced deep learning into their search system. Today’s paper choice highlights an organisation that has been deploying multiple deep learning models in search (visual search) for a while: Pinterest.
Kubernetes goes worldwide with kubeCDN. In this blog post, Ilhaan discusses the design and implementation of kubeCDN , a tool designed to simplify geo-replication of Kubernetes clusters in order to deploy services with high availability on a global scale. More Users, More Problems The internet has transformed how people exchange ideas and share results across the globe.
WebPageTest is an online tool and an Open Source project to help developers audit the performance of their websites. As a Web Performance Evangelist at Theodo , I use it every single day. I am constantly amazed at what it offers to the web development community at large and the web performance folks particularly — for free. But things can get difficult pretty quickly when dealing with Single Page Applications — usually written with React, Vue, Svelte or any other front-end framework.
Scaling is one of the many promises of adopting a microservices architecture. By splitting up an application into smaller parts, organizations hope to allow more development teams to work autonomously, without conflicting with each other, and ultimately allow a successful product to grow faster.
When was the last time you were in the flow while working through some code? Reading code or doing code reviews is an activity that we do often, yet we don’t often get into the zone doing it. Too many times, we have to slow down, check that last line again or try to figure out the structure of the code. Even though we all follow the same principles for clean code, there is always that gut feeling that tells you that one style is better than the other.
Sometimes the start is the most difficult part. You may also like: Using Java's Future and ExecutorService. If you have ever implemented an async API / Event listener then the following would have been the typical implementation. High-Level Diagram of the Implementation.
In this week's roundup, Lighthouse sheds light on third-party scripts, insecure resources will get blocked on secure sites, and many country connection speeds are still trying to catch up to others. literally. Measure the impact of third-party code during page load. Lighthouse, Chrome’s built-in auditing tool, now shows a warning when the impact of third-party code on page load performance is too high.
Did you ever look at a failed message in ServicePulse and think "I wish I could just edit this quickly and dump it back in the queue" ? Yes, you should follow best practices and investigate the root cause and make sure the error doesn't come back, but the real world moves faster than that and sometimes you just need to get &#@%! done and figure it out later.
Applying deep learning to Airbnb search Haldar et al., KDD’19. Last time out we looked at Booking.com’s lessons learned from introducing machine learning to their product stack. Today’s paper takes a look at what happened in Airbnb when they moved from standard machine learning approaches to deep learning. It’s written in a very approachable style and packed with great insights.
Have you ever faced a situation to automate the way you inspect the network calls of a webpage? Have you ever thought about automating the process of capturing the HTTP content and export the performance data as a HAR file? Well! In this article, we are going to see about how to capture all network calls and capture every resource loaded on a browser and export them as a HAR file using selenium and BrowserMob-Proxy in Python.
