Docker is a containerization technology that allows developers to package and deploy applications in lightweight, portable containers. These containers are isolated from the host operating system, which makes them portable across different environments and eliminates the “works on my machine” problem. Docker is a popular platform for creating and managing containerized applications; however, several alternatives for Docker can also be used for this purpose.

As more and more workloads are migrated to the hyperscaler cloud-service providers, the utilization of cloud services is now standard for many organizations. When customers utilize the services of a specific cloud provider, such as Microsoft Azure, users within the organization eventually become experts in working with, administering, and managing the cloud resources of that provider.

As Ibrar Ahmed noted in his blog post on Transparent Database Encryption (TDE). PostgreSQL is a surprising outlier when it comes to offering Transparent Database Encryption. Instead, it seems PostgreSQL Developers are of the opinion that encryption is a storage-level problem and is better solved on the filesystem or block device level. I do not share that opinion, and according to a poll I did late last year, many PostgreSQL community members don’t either.

That means members see the assets that are most likely to help them make an informed choice. These assets are a critical source of information for the member to make a decision to watch, or not watch, a title.

For most of the past decade, I have spent a considerable fraction of my professional life consulting with teams building on the web. It is not going well. Not only are new services being built to a self-defeatingly low UX and performance standard, existing experiences are pervasively re-developed on unspeakably slow, JS-taxed stacks. At a business level, this is a disaster, raising the question: "why are new teams buying into stacks that have failed so often before?

Big data is at the center of all business decisions these days. It refers to large volumes of data generated through different sources, and this data then provides the foundation for business decisions. The concept of data has been there for centuries, but only now do we have enough computational resources to process and use that data. There are different ways through which we can process data.

Plot showing the final result of fitting multiple normal distributions to a response time curve Most people have figured out that the average response time for a web service is a very poor estimate of it’s behavior, as responses are usually much faster than the average, but there’s a long tail of much slower responses. The common way to deal with this is to measure percentiles, and track the 90%, 99% response times for example.

PostgreSQL is a fantastic database, but if you’re storing images, video, audio files, or other large data objects, you need to “toast” them to get optimal performance. This post will look at using The Oversized-Attribute Storage Technique (TOAST) to improve performance and scalability. PostgreSQL uses fixed-sized pages, which makes it challenging to store huge data values directly.

These days, the typical PostgreSQL cluster consists not only of a multi-node replication cluster, which is ordinarily an asynchronous streaming replication model but can sometimes include a logical replication component. Recall that logical replication works by using the PUB/SUB mode, where individual tables are published and are then subscribed by remotely connected databases/tables.

What problems of the Ingress API does the new Gateway API solve? Does this mean the end of the Ingress API?

I recently came across a box of very old technology tucked away in my basement: PDAs, mobile phones, digital cameras and even a couple of old laptops, all over two decades old. It was an interesting find, if slightly disturbing to think this stuff has moved house a couple of times. Before disposing of something, I try to repurpose it if I can. That's hard to do with electronics once they're orphaned by their manufacturers.

Rather than competitors duplicating effort to come up with multiple suboptimal solutions, they can collaborate together to build something greater.
