I have a surveillance camera system using four (cheaper) wireless cameras and Zoneminder to monitor and record events. I’ll discuss this setup in more detail in a future post. For now though, I want to describe how I set up a spare Raspberry Pi as a viewer for the four cameras. This is just loading the URL for the “montage view” in Zoneminder, which let’s you see all your cameras arranged in a grid.
I ran into a weird problem with Ubuntu 18.04 on one of my computers recently. I was performing a regular software update via the Software Updater GUI when the install got stuck at Installing for x86_64-efi partition. I left the computer for a couple of hours but the install never moved beyond this point, so I had to find the updater process and kill it. I had a feeling that things weren’t going to behave nicely after a reboot since I had interrupted an update in the middle of a GRUB install.
Building the Internet of Things is not a process that happens overnight, nor is it being built by any single entity. Every device that is capable of connecting to the internet automatically becomes part of the Internet of Things. It’s an ever expanding network that isn’t going to exist, it already exists. This network feeds off data. It requires it in order to function and provide us with the conveniences that we enjoy in our daily lives.
The Internet of Things is one of the latest buzzwords of 2013; however, the concept has actually been around since 1999. Imagine a future where everything contains sensors that are connected to the internet in one way or another, and instead of people recording data, machines do it. That future is already here. In 2008, the number of devices connected to the internet surpassed the number of humans on Earth. By 2020, the number of devices connected to the internet are expected to be in excess of 50 billion.
Companies often face a fundamental challenge when it comes to technology. Evolve and adapt or die. There is no in-between. There is no holding on to old business models. Technology is a cruel and unforgiving mistress that changes at an astounding pace. It has systematically changed entire centuries-old industries such as print and newspaper production. Conventional printed books and newspapers are beginning to become an endangered species, in favour of digital books and online content.
The word hacker often conjures up images of seedy guys in dimly-lit basements, banging away on keyboards and trying to get into government networks. These hackers use their skills for malicious intent and are called crackers. They are individuals who actively break the law to gain unauthorized access into computer networks that they don’t own or control, either to cause destruction or for financial gain. Unfortunately, the word hacker has a negative connotation because of the mainstream media.
