Core Web Vitals Wordpress performance is important for user experience, for search optimisation. Learn how to improve wordpress and recaptcha CWV.

Speedup wordpress by dequeing unused scripts and css. The Events Calendar is used as an example. Faster load, less parse, better core web vitals.

Latency, specifically DNS Latency, is a big factor in web page load time. Don’t over-focus on bandwidth, examine prefetch and latency to improve.

Web site performance. Search engines favour sped. Milliseconds matter. Performance is as important as the content, as important as the appearance.

Your web site uses new technology. Shake it down by using your Sitemap for Latency and load testing with locust and istio.

Cloud Native: embracing failures. Assume Strength in Numbers. Don’t spend large time on a single infinitely reliable thing, assume each component will fail.

CNAME. Invented in 1987, used in today’s SaaS. See how your domain can be shared with your partners.

Concerned about the new dockerhub rate limits? Run Kubernetes? Run CI? Deploy a pull-through cache simply to reduce the risk and impact.

Email. Port 25. Security. Spam. Its more complex than it used to be to be a good Internet citizen for email sending. Cloud edition.

Take Wordpress. Modernise it. Make it cloud-native. Add tidb cloud-native database. Add stateless storage.

OpenID Connect, a powerful single-sign-on with strong security, and locking the user to the upstream ID means if their name changes you are insulated.

Large legacy systems hold our data hostage. Tame their grip with REST-ful API’s and microservices. Fear no more on upgrades or even replacements.

Secure. Reliable. Economical. All three. We have embraced failures to create a reliable municipal hybrid cloud with unreliable components, economically.

Declarative. It becomes a way of life. We have chosen kustomize to safely build our inventory of YAML, including Istio and Cert-Manager. But, it has proven incredibly non-DRY. After some refactoring etc, I made a few Generators and Transformers to cover some of the most common cases. And, today, for the low low price of…

Prevent accidents from happening on un-merged feature branches with GitFlow and kustomize.

Ever wondered why so many breaches happen due to secrets being checked in to source control? Want to make it easy to commit them to git, and be secure at the same time? Read On!

TLS certificates, unlike wine, do not get better with age. Refresh them before they hit the end of their lifecycle.

Wide open elasticsearch on the Internet. Its common. The user usually believes since they use private IP (NAT) they are protected. Wrong.

Secrets get committed to git, forgotten, and then resurrected by the wrong people later. Don’t let this happen to you, use sops. And be declarative, use kustomize. And do it with this cool new library I wrote.

Amplification attacks occur when a small request causes a larger response. NTP and DNS have both been prone to this, but now cloud logging? Read on!

Using fluent-bit annotations can increase the usefulness of your Kubernetes nginx-ingress logging. Create a custom regex parser.

The (memory) cost of all the security proxies can be higher than the thing they protect. Let’s look at Istio.

Google API keys. Powerful. Commonly used on websites. But able to cost you a lot of money. Learn how to protect them and your wallet.

Fluent-Bit log routing by namespace or by cluster. Route the logs from the right input(s) to the right outputs in fluent-bit in kubernetes.

Cloud. It achieves its elastic nature using Load Balancers and Proxies. The sad side affect of these is they remove the source IP. Let’s try to bring it back.

Ever wanted to apply Kubernetes secrets without displaying or persisting the secret value? Well now you can: Unix to the rescue!
