Basic DHCP concepts

Let’s step back and take a very basic look at DHCP. In fact, let’s look at the analogy of assigning a street address to your house. Usually, this is done by the local 911 dispatch office, or some other central authority. They typically use either a survey map or a latitude, longitude pair to locate you, before they assign your house numbers from a pool of available addresses, compatible with other addresses in the area.

Two-factor authentication coming to Ubuntu One

Two factor authentication (2FA) increases your account security further than just using a username and password. In addition to a password (the first factor), you need another factor to access your account. A great example to demonstrate this is when you withdraw money from an ATM. To access your bank account you need both your physical bank card and to know your PIN number. These are the two factors you need to withdraw money = 2 factor authentication!

Spot by NetApp joins AWS CloudFormation Public Registry

Repetition is super helpful when learning something new. But eventually we get tired of repetitive tasks, errors start creeping in and the tedium saps us of the creative energy we need to innovate and problem-solve.

Using the Redis Command-Line Correctly

Redis is an open-source in-memory data store. You can use Redis as a database, message broker, or cache. It also supports Lua script evaluation so you can build automation scripts or custom operations on top of your key-value Redis store. Typically, developers use language-specific client libraries when building apps with Redis. These clients abstract Redis’ command-line interface (CLI), making it easier to work with but more work to set up.

Have you ever heard the mantra “Don’t deploy on Fridays?” There are blog posts, tweets, and t-shirts shouting this slogan to anyone who will listen. Maybe your organization follows this policy. The purpose of not deploying on Fridays is to give the team better work/life balance by preventing them from having to work on the weekends if something goes wrong during or after the deployment.

Complex Messaging Workflows on Demand with VMware Tanzu RabbitMQ 1.1

Three months ago, we launched VMWare Tanzu RabbitMQ for Kubernetes to automate high-performance messaging on demand with our cluster Operator.* Since then, customers have approached us with higher-level needs that inspired us to extend and improve Tanzu RabbitMQ. In other words, you’ve spoken, and we’ve listened. And so now, in version 1.1, we go well beyond automating cluster operations to orchestrating complex topologies, adding alerts, and previewing active-passive replication.
