Monitor a UPS with a Mikrotik router via SNMP


↺ Monitor a UPS with a Mikrotik router via SNMP


> Cyberpower UPS units saved me from plenty of issues in the past with power outages. However, although I love the units themselves, I found that the quality of replacement batteries varies widely. This leads me to keep a close watch on my UPS units and test them regularly. Energy conservation ranks high on my list of priorities, too. I monitor the power draw on my UPS units to know about usage spikes or to review electricity consumption after I make changes. My Raspberry Pi did a great job of monitoring my UPS for my network devices but it failed after a recent reboot. My network woes from September left me with a Mikrotik hEXs running my home network and I noticed it had a USB port.

↺ How to use Tmux mouse mode

If you have used the terminator application previously, you should be familiar with this app. With the aid of Tmux, users can split the terminal into several panes, adjust the pane size, move the panes around, and switch between them.

New user guide: How to organize your qubes | Qubes OS


↺ New user guide: How to organize your qubes | Qubes OS


> When people first learn about Qubes OS, their initial reaction is often, “Wow, this looks really cool! But… what can I actually do with it?” It’s not always obvious which qubes you should create, what you should do in each one, and whether your organizational ideas makes sense from a security or usage perspective.


> Each qube is essentially a secure compartment, and you can create as many of them as you like and connect them to each other in various ways. They’re sort of like Lego blocks in the sense that you can build whatever you want. But if you’re not sure what to build, then this open-ended freedom can be daunting. It’s a bit like staring at a blank document when you first sit down to write something. The possibilities are endless, and you may not know where to begin!


> The truth is that no one else can tell you exactly how you should organize your qubes, as there is no single correct answer to that question. It depends on your needs, desires, and preferences. Every user’s optimal setup will be different. However, what we can do is provide you with some illustrative examples based on questionnaires and interviews with Qubes users and developers, as well as our own personal experience and insight from using Qubes over the years. You may be able to adapt some of these examples to fit your own unique situation. More importantly, walking you through the rationale behind various decisions will teach you how to apply the same thought process to your own organizational decisions. Let’s begin!



Humans may be rational, or how to collect better documentation feedback with linguistic theory | Ubuntu


↺ Humans may be rational, or how to collect better documentation feedback with linguistic theory | Ubuntu


> Anyone who has ever built a product wants user feedback – and we in open source want it more than anyone else, and place higher demands on it than anyone else. However, this feedback can be hard to give, hard to receive, and hard to act upon.


> My product is open source software documentation, and the same is true of it too, but, at least in the case of documentation, I believe there’s a way to make feedback easier and more effective – all thanks to linguistic theory.


> The reason is because documentation is a product that relies on natural language. While we’re not all experts on documentation, and we’d be wrong to believe that we are, we are all experts in natural language, and we’d be wrong to believe that we are not. And – as I argue below – this makes all the difference.
