Do you have a website hosted on a server somewhere – either in your home or in the cloud? Has it ever gone down and you didn’t know about it for hours? I have, and it has happened to me too many times.
As a result, I have often wanted/needed a way to verify that the server which is hosting my websites is up and running properly. While many fine graphical tools exist such as Munin for this purpose, I wanted a simple set of utilities that could return just the parameters I needed and how I needed them.
There are two different ways in which I want to get my metrics. The first is a command-line utility that I can run from my local computer to test the parameter needed. The second is a set of python functions that deliver the same metrics that I can then use to create a custom webpage.
This webpage (a future project) would run on a local server such as a Raspberry Pi, which could then display all my metrics on a tablet display in a convenient location. A quick glance could then show that everything was running smoothly or … Read the rest
I wrote previously about why you should switch to Linux for all your computing needs. I would like to amplify on that assertion. There has never been a better time to abandon Windows and switch to Linux. First I’ll address the disaster that Microsoft Windows has become, and then explore the Linux alternative.
Window’s Ship is Sinking
Just like the Titanic, even though there is widespread denial, Windows is sinking into the abyss just as surely. Despite the grave metaphor, I am not saying Windows will completely go away (who knows for sure), but it will continue to shrink into irrelevance. Linux rules both the server/cloud world and dominates the mobile market as well via Android. As applications continue to move to the cloud and mobile, the raison d’être for Windows as the only platform that can run the applications a user needs is slipping away.
But irrelevance is not the only thing ailing Windows. No siree. The operating system is strangling itself. Years of legacy code combined with a closed development system has left Windows years, even decades behind its competitors, namely Linux. Even the mighty resources that Microsoft have at its disposal cannot hope to compete with the … Read the rest

With the loss of updates for Windows XP and Microsoft’s floundering on Windows 8/10, many have started to consider alternatives. The MacOS is of course an option, but I believe Linux to be an even better one. Not only is Linux a good alternative to Windows, but for makers, hackers, tinkerers and homeschoolers especially, Linux is really the only operating system (OS) worth considering.
Without a doubt, Linux is the ultimate low-cost operating system. It is absolutely free. How many times have you had a computer where the OS needs to be reinstalled? With Windows systems so vulnerable to malware infections, it is a regular occurrence. When you do need to reinstall, do you still have the original disks? Can they still be read?
What about upgrades? If you get a new computer (without an OS), and you want to install your latest version, do you have the full version, or just an upgrade version? If it is just an upgrade version, do you have the original version disks? If not, Microsoft’s DRM will not allow the installation.
Have you ever thought about building your own computer, but are stymied by the prospect of having to shell out … Read the rest
