INDUSTRY INSIGHTS YOUR PEERS ARE READING
Declarative assembly of web applications from predefined concepts De Rosso et al., Onward! 2019. I chose this paper to challenge my own thinking. I’m not really a fan of low-code / no-code / just drag-and-drop-from-our-catalogue forms of application development. MORE
Benchmarking spreadsheet systems Rahman et al., Preprint. A recent TwThread drew my attention to this pre-print paper. When spreadsheets were originally conceived, data and formula were input by hand and so everything operated at human scale. MORE
What happens when you page loads too slowly. Recently we troubleshooted a performance issue, reported by one of the customers of Plumbr who was using our Real User Monitoring solution. MORE
Learn how to test with Spring Cloud. With many industries transforming to a microservices architecture, testing these microservices is a challenge. Different teams own different services, so testing and validating the API communications between these microservices is important. MORE
By having appropriate indexes on your MySQL tables, you can greatly enhance the performance of SELECT queries. But, did you know that adding indexes to your tables in itself is an expensive operation, and may take a long time to complete depending on the size of your tables? During this time, you are also likely to experience a degraded performance of queries as your system resources are busy in index-creation work as well. MORE
We make hundreds of decisions every day at our jobs. Surveys have found that at most companies, the majority of decisions are made based on gut feelings and experience, instead of data and information. As a technical writer, it can be difficult to know what data to use to guide decisions. As you document features, best practices, and getting started guides, you hope that you are making each user’s life easier. But how can you use quantifiable metrics to demonstrate that you have? MORE
Dynatrace news. Accelerated delivery is one of the key principles of good user experience, and improved user experience leads to a better bottom line for companies. Customers enjoy using your digital channels more and buy more from your company. MORE
Dynatrace news. Kubernetes automatically validates the health of your pods within your k8s cluster, by continuously evaluating the health end-points (livenessProbe and readinessProbe) of your deployed services. MORE
I have previously tested and blogged about the NTFS, sparse, file system limitation error 665: [link] when running DBCC or using Snapshot databases with SQL Server. Recently a customer asked me if they would encounter the same limitation if they moved to Linux. The answer is not the same limitation and for EXT and XFS my testing and research confirm that a sparse file on Linux may be able to accommodate more fragments than on NTFS. MORE
In this article, we’ll discuss data type VARCHAR and query performance issues associated with utilizing the lower level VARCHAR data type. CHAR, VARCHAR and NVARCHAR are data types that support storing information in text format in a SQL Server database. MORE
For some reason, the notion of individual performance reviews comes up a lot. My general feeling is that we should dump them entirely. I’m actually in good company. Almost a third of U.S. companies are dropping individual reviews, including stodgy places like General Electric. See this HBR article. There are books written on the subject,… The post Individual Performance Appraisals, Just Say No! appeared first on Allen Holub. Agility MORE

Efficient lock-free durable sets Zuriel et al., OOPSLA’19. Given non-volatile memory (NVRAM), the naive hope for persistence is that it would be a no-op: what happens in memory, stays in memory. MORE
The notion of technical debt is not well understood, so let’s start there. Agile is all about fast feedback loops. Deliberately lengthening your feedback loop in pursuit of the chimera of perfection destroys your agility. The cost of that delay is a real cost. It usually exceeds development costs by a large factor. Deliberately delaying… The post Technical Debt appeared first on Allen Holub MORE
