Using an SSH key pair is my perfered method of authenticating with a server, such as web hosting.
From the command line:
ssh-keygen -t rsa -b 4096 -C "my config description"
-t rsa: Specifies the type of key to create (RSA)
-b 4096: Specifies the number of bits in the key
-C An optional comment to describe the key
2 files will be generated, a private key and a public key (.pub extension). The public key is used on the hosting site. The private key is never shared.
Files can be edited with a...[more]
AI is everywhere. I've even started asking ChatGPT for solutions rather than visiting Google. GPT may not always be bang on, but it's (for me, at least) usually more bang on than an aggregation of results based on key words and overall page rank.
The science behind Artificial General Intelligence (AGI) fascinates me. On one hand, I have no idea where to begin my thought process. On the other, it makes sense that the human brain is a pretty reasonable starting point. But, and it's a big but, is that over-...[more]
Take a look at the moon and you'll always see the same 'face'. But surely the moon rotates on its axis? And what of this so-called 'dark side of the moon'.
I had to find an answer for this as it's the sort of thing that bugs my brain as I'm driving home at night.
The moon rotates. That is a fact. But it completes one rotation in pretty much the amount of time it takes to circle the Earth. Approximately 27.3 Earth days.
The Earth completes one rotation on its axis every 24 hours. At least, that's how lo...[more]
In short, no.
This stuff fascinates me and since reading Prof. Brian Cox's Human Universe, I've wanted to pursue it a little.
It seems to be a common misconception that we are descended from the ape family because we appear to have common traits: be-pedal, thinking, dexterous etc. This would imply that apes, as we see them today, have been around for millions of years and that humans evolved from them.
The reality is that humans share a common ancestor with today's apes. Quite what that common ancestor...[more]
I've always loved the original DOOM games. I was in my early 20s when the first one hit and it hit hard. I can still remember seeing it running on a PC during a night shift and instantly diving in to have a 'go'.
The fact that the whole thing moved and moved quickly struck me as nothing short of witchcraft. How on earth is this possible? PC games up to that point (I'd never encountered id's previous titles) were, for me, the domain of platform games and worthy flight simulators. To be running down corridor...[more]
If the conditions for life on Earth are not as extraordinary as we think they are, is it possible that mammals would never get a chance elsewhere in the Universe and we have intelligent dinosaurs roaming around on other planets?
This is the kind of thing that keeps me awake at night.
I love playing Minecraft. It's my switch-off after a busy day.I don't tend to play it as it 'should' be played (i.e. fighting my way to the end and defeating the Ender Dragon) but I do always play in Survival Mode. Where's the fun without a challenge, hey?
So, my main aim when playing Minecraft is to create a village. Sometimes villages become towns and on the odd rare occasion they become quite a bit bigger after weeks of modifications.
I recently started a new world and walked, swam and rowed around 40,...[more]
A few years back (not that many years) I fulfilled I lifelong goal to write, illustrate and publish a children's picture book.
That first book was called A Frog Named Bob and told the story of a young frog who didn't know what sound he should make. So, to find out exactly what sound a frog should make he hopped around his animal friends to see just what sound they made.
Of course, a neigh, a moo, an oink or a bleet weren't going to cut it so Bob pretty much gave up. Until that is, a girl frog sat be...[more]
Not much to do on a bank holiday Monday so I took myself off to Repton to (finally) go and see the 7th century church of St. Wystan.
I'd always been fascinated by the fact that the Vikings had raided and laid waste to much of the place, but ultimately there's so much more to the church and the settlement of Repton in general.
Repton is situated in the heart of the ancient kingdom of Mercia. As many notices around the town will tell you it was, in fact, the kingdom's capital. But that all changed fol...[more]
