Krew is a package manager for Kubectl, the official Kubernetes CLI. Using Krew you can find, install, and update Kubectl plugins that extend the CLI with additional functionality. Kubectl’s plugins mechanism supports several plugin installation methods. The simplest way is to pop plugins straight into a directory that’s in your PATH. This is a manual process which offers no way to update the plugin as new releases are published....
Anybody who has been around the internet for a while knows about ActiveX controls and their historical security problems. Here’s how to use ActiveX filtering in IE9 to prevent being hijacked by a virus while browsing. What Is An ActiveX Control? ActiveX is a standard dreamed up by Microsoft so that you can make use of the same code across multiple programs without “re-inventing the wheel” as developers like to call it....
Writing scripts to run on different Linux computers is tough. You can’t assume they’ll have the same characteristics. The getconf command lets you check hundreds of operating system and file system values. Hardware Aware Scripts If you’ve ever written a script that has to run on a variety of Linux machines, you might well have found yourself facing the “Strange, it runs just fine on my machine…” quandary. Small differences between computer architecture, operating systems, and file systems on the target machines can prevent your scripts from operating correctly....
You’ve seen it in magazines, photo websites, advertisements, and loads of other places—that romantic, almost saccharine look applied to an image to soften skin texture and create “glowing” portraits. Here’s how to get that supermodel glow in under a minute. You can apply this effect to nearly any image, but it will probably do its best work improving portraits or pictures of people. But if you’re like most of us, you probably have a lot of these kinds of pictures....

BatchPatch, an application developed by Cocobolo Software, was initially developed to aid in the facilitation of Windows patches. Still, over time it has morphed into a tool that SysAdmins may find themselves using every day. Let’s go over how you can use this to apply Windows patches to some remote servers. Let’s Cover a Few Assumptions Before we dig into the steps to manage updates on remote servers, we need to cover a few assumptions....
Over time, with some neglect and potential laziness, your Google Drive can accrue tons of files and become a mess to find anything. Here’s how to organize your Drive to find everything fast and make sure it stays in order. Organize Your Files Into Folders One of the easiest ways to organize your Google Drive is to create category-specific folders. For example, you could have separate folders for pictures, documents, projects, or other descriptions to help you locate files....
Docker’s API is completely unprotected by default except for filesystem permissions on its Unix socket. You should set up TLS when exposing the Docker API over TCP so Docker Engine and your clients can verify each others’ identity. Otherwise anyone with access to the TCP port could browse your Docker containers, start new ones, and run actions as root on your system. Configured TLS will require clients to present a valid certificate that’s signed by the server’s certificate authority....
Built a Docker image that you need to share with a colleague? Here’s how you can distribute an image without the recipient needing to run docker build themselves. Sharing a pre-built image instead of a Dockerfile lets you be sure your colleague is running the exact same software. Re-running the build could result in a subtly different environment. You’ve got two options to distribute your image, depending on the situation....
Kubeadm is the official tool for installing and maintaining a cluster that’s based on the default Kubernetes distribution. Created clusters don’t automatically upgrade themselves and disabling package updates for Kubernetes components is part of the set up process. This means you have to manually migrate your cluster when a new Kubernetes release arrives. In this article you’ll learn the steps involved in a Kubernetes upgrade by walking through a transition from v1....
Plex Media Server does a pretty decent job automatically downloading cover art, backgrounds, and other artwork on your behalf, but that doesn’t mean every piece of artwork it picks is the one you want. Fortunately, changing out the artwork is a snap. Why Change The Media Artwork? Stocking all the TV shows and movies that end up on your media server is just part of the media center experience. The other big component is the presentation; how that media looks on the screen as you happily scroll through it all, enjoying the analysis paralysis that comes with curating a vast collection of your favorite content....
Docker’s ONBUILD instruction lets you set up triggers within an image. Your triggers will be executed later, when the image is used as a base for another one. They’ll become part of the new downstream image context and won’t be filesystem layers in your initial docker build. Adding ONBUILD Triggers ONBUILD is an instruction you write into your Dockerfiles. It’s unique as it accepts another instruction as its argument. You can specify any Dockerfile operation, such as COPY or RUN, and have it be executed during a downstream image build....
Microsoft has dropped a new Search box into Outlook’s title bar. At first glance, it’s very similar to the old Search box, but it has a lot of new tricks up its sleeve. Here’s how to use the feature effectively. Microsoft Outlook, along with the other Office apps, now has a new Search box in the title bar. This is called Microsoft Search, and it’s available in both the client apps and the web apps in Microsoft 365 (M365)/Office 365 (O365)....

For those of you that haven’t seen it, here’s what the Eclipse Open Resource dialog looks like. And here’s a screenshot of VSFileFinder in action. You’ll notice that it’s very similar, but it doesn’t show open files first. The first thing you’ll need to do is download and install it from the CodeProject site (registration required). Next to set a shortcut key for it, you’ll want to open Tools \ Options and then browse down to Environment \ Keyboard...
What Is S3 Compatible? In many cases, if you move to another cloud provider, you will have to rework a lot of your application. But, if you’re using S3 as your object storage backend, you’ll be able to move seamlessly to many other services. This is because S3 is an open API standard. AWS’s Simple Storage Service is just an implementation of this standard; it’s native, and obviously will have the best support, but there are other services that will offer acceptable performance and stability, often for lower cost....
Sometimes, graphics editing is useful. And sometimes, you use it to turn things invisible just because you can. Here’s how to make invisibility cloaks in Photoshop in a few minutes, with our GIMP friendly technique. Collecting Your Source Images While you don’t have to, your best bet is to take your own pictures. The best way to do this is with manual camera settings and a tripod. Your goal is to shoot a subject in front of some environment, ideally one with a lot of detail....

Kubernetes image pull policies control when Kubelet should fetch an updated image version. Pull policies are used when a new Pod is starting up. Kubelet will take the appropriate action indicated by the Pod’s policy. The Default Behaviour You don’t have to specify an image pull policy. When a Pod lacks a policy, Kubernetes will infer your intentions from the image’s tag. If you’ve supplied a specific tag (such as my-image:my-release), the image will only be pulled if the tag doesn’t already exist on the Kubelet node....
Classic Shell is an open-source utility that brings classic Windows features to newer versions of Windows. It offers the most classic Start menu for Windows 8 yet, and it lets you avoid the ribbon with a Windows Explorer toolbar. We’ve also written about getting a Windows 7-style Start button with ViStart and a Metro-style Start menu with Start 8. Or, if you’re brave, dive into the deep end and try living without the Start button for a while....
