Reading time 9 min When it comes to managing web performance, it’s vital to be proactive rather than reactive. To accomplish this goal, an organization needs to build internal processes and procedures that can operationalize a performance-first culture. The first step is to establish and implement web performance budgets. According to Tim Kadlec : A performance budget is a clearly defined limit on one or more performance metrics that the team agrees not to exceed and that is used to guide design
Testing on Google Chrome is necessary for any app-designer. Internet usage has constantly exploded in the past decade and continues to grow every single day. Currently, global Internet traffic counts to a whopping 4.3 billion users. In the early days of the Internet, we hardly had a couple of browsers to choose from like Netscape (now known as Firefox), and Internet Explorer.
Migrating an on-premises SQL Server instance to an Azure Virtual Machine (VM) is a common method to migrate to Azure. IT professionals are familiar with scoping the size of VMs with regards to vCPU, memory, and storage capacity. Microsoft offers multiple VM types and sizes for an organization's needs. You'll see the types referenced as Family in the Azure Portal when sizing a VM.
Thoughtful and effective decision-making was a key trend at the O’Reilly Software Architecture Conference in Berlin 2019. The ability to make good decisions might be the most important aspect of a software architecture practitioner’s job. Every day.every week.every month, you make critical architectural decisions. Since the architecture reflects the overall business, it’s fair to say that every successful business has a good architecture, and that every good architecture can be traced to proper
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.

In a classic 1983 paper , cognitive psychologist Lisanne Bainbridge drew attention to a curious irony: so-called “automated” systems were, in practice, usually attended by one or more human operators. The more advanced the system, she observed, “the more crucial…the contribution of the human operator.” Bainbridge believed that automation designers were in denial about this, however.

Local-first software: you own your data, in spite of the cloud Kleppmann et al., Onward! ’19. Watch out! If you start reading this paper you could be lost for hours following all the interesting links and ideas, and end up even more dissatisfied than you already are with the state of software today. You might also be inspired to help work towards a better future.
Performance testing makes the world turn. You may also like: Lessons From the Birth of Microservices at Google. You may have heard that as of early July, Google updated its search algorithm to include the load time of mobile URLs.

Dynatrace news. Dynatrace management zones provide an effective means of collaborating across teams by enabling you to define fine-grained access control to specific segments of monitoring data. Synthetic monitors (both HTTP and browser) can be assigned to management zones based either on their names or tags. Until now, users had to have the Change monitoring settings permission across an entire environment before they could create synthetic monitors.
Introduction. An Eager Index Spool reads all rows from its child operator into an indexed worktable, before it starts returning rows to its parent operator. In some respects, an eager index spool is the ultimate missing index suggestion , but it is not reported as such. Cost assessment. Inserting rows into an indexed worktable is relatively low-cost, but not free.
The Android platform, now more than 10 years old, has plenty of testing tools available. Java is even more mature, with a rich assortment of testing tools for Android projects.
Do you know what to test? You may also like: How and Why We Moved to Vue.js. The most common question about unit testing Vue components I see out there is "what exactly should I test?" While it's possible to test either too much or too little, my observation is that developers will usually err on the side of testing too much. After all, no one wants to be the guy or girl whose under-tested component crashed the app in production.
Dynatrace news. Imagine a situation where you have 1,000 hosts to monitor. Regardless of how awesome the default settings are, at some stage, you’ll want to change the configuration of some of these hosts. For example, you might want Dynatrace to treat a group of hosts in a load-balancer environment as a single virtual host. This is possible via the host-group feature, but until recently, required a full OneAgent installation.

Formal foundations of serverless computing Jangda et al., OOPSLA’19. Jangda et al. won a distinguished paper award at OOPSLA this year for their work on ‘Formal foundations of serverless computing.’ Central to the paper is their observation that the serverless execution environment has a number of unique properties (such as warm starting / reuse of execution environments) that can make it harder build correct applications.
Google needs to step up their speed. Quantum Supremacy Is Arguable, but We Are Almost There. Last month , I reported on a leaked announcement that Google had proved “ quantum supremacy ”, which is a concrete illustration of a use case where a quantum computer succeeds in a computation that a classical supercomputer cannot achieve in any reasonable timescale.
When most people test their site speed, they test a single, static page. That works well for testing home pages, or product pages – but what about a checkout process? Or a page that’s protected behind a login? How do you test more complex, multi-step processes? Luckily WebPageTest (and thus MachMetrics) offers scripting functionality that allows you to create these specific, multi-step tests that can be useful in certain situations such as: Testing a page that is only accessible afte
PlanAlyzer: assessing threats to the validity of online experiments Tosch et al., OOPSLA’19. It’s easy to make experimental design mistakes that invalidate your online controlled experiments. At an organisation like Facebook (who kindly supplied the corpus of experiments used in this study), the state of art is to have a pool of experts carefully review all experiments.
Testing for fragmentation. Everyone who has been involved with testing apps or web applications knows the trouble different platforms and browsers can cause. Things that work perfectly fine in one browser, break down suddenly and spectacularly in another one (I’m looking at you, IE11).
