" Remember, it is the dumb, novelty-seeking portion of the brain driving the limbic system that induces this feeling of pleasure, not the planning, scheduling, higher-level thought centres in the prefrontal cortex. Make no mistake: email-, Facebook- and Twitter-checking constitute a neural addiction "

Growth Mindset

Carol Dwek - thank you smile A 'Growth mindset', simple, powerful, should be at the core of every students thought process. Something which I've been wondering about for years and had confirmed is the difference between a 'fixed' and 'growth' mindset.

Disinformation in a time of crisis

Visible to anyone in the world
Edited by George Muirhead, Thursday, 18 Jun 2020, 06:15
In a time of such unprecedented measures being imposed on the global population, I came across a few pieces of very poignant observation, which I think everyone could benefit from, before making uninformed comments about Corona Virus Disease 2019, (previously known as “2019 novel coronavirus”) There is no treatment for it, despite all the rubbish you read on social media,"There's so much noise, everybody wants to have a point of view." (Stephen Fry, 2020), it's the 'experts', people should be listening too, not ill-informed panicky jittery rubbish proliferated on social media, "But the fact is, if you listen to the scientific advisers, they almost always begin every sentence, with, 'we think', 'it's possible', 'maybe', 'perhaps', 'we don't know, but', that's how experts talk, people who really understand it." (Stephen Fry,2020) — "Prof Christine Jenkins, chair of Lung Foundation Australia and a leading respiratory physician, told Guardian Australia: At the moment there isn’t any established treatment apart from supportive treatment, which is what we give people in intensive care. " (Graham Readfearn, 2020) "Experts, like the rest of us, have no access to infallible truths in unprecedented crises. The stakes could scarcely be higher, but the scientific bets being laid involve judgments, not certainties. The government, advised by Sir Patrick and Prof Whitty, believes that drastic action to suppress coronavirus could store up bigger problems down the line, when measures are relaxed. Therefore, they judge the least-worst outcome for the country will be a managed epidemic which peaks gradually, so that the NHS is not overwhelmed, and creates “herd immunity” to what could become an annual virus. There is also concern that forcing people into more isolated lives too soon could be counterproductive. Sir Patrick has predicted that the epidemic’s peak in Britain could still be 10 to 14 weeks away; too much isolation too soon could lead to coronavirus “fatigue”, causing people to revert to old ways at precisely the wrong moment."

GNU and the history of recursive acronyms

Visible to anyone in the world
GNU is a recursive acronym for "GNU's Not Unix!",chosen because GNU's design is Unix-like, but differs from Unix by being free software and containing no Unix code. A recursive acronym is an acronym that refers to itself. The term was first used in print in 1979 in Douglas Hofstadter's book Gödel, Escher, Bach: An Eternal Golden Braid, in which Hofstadter invents the acronym GOD, meaning "GOD Over Djinn", to help explain infinite series, and describes it as a recursive acronym.

Thinking about SALT and HASHING

Visible to anyone in the world
My understanding of hashing and salting, and the process: Things to remember: It's used to guard against dictionary attacks it's used to thwart brute force attacks Process: 1 Salt is generated: [usually in proportional length] relative to the SHA being deployed. The hash value is generated. The salt is added to the beginning of the hash value. The salt is added to the end of the hash value. Remember: Binary is base 2 Explanation and Example: 2-bit salt The number of bits is in relation to the number of binary bits [1's and 0's] contained within each little binary container. This means each little binary container [contains within it] 2 to the power of 2, thus: 00 01 10 11 Now 2 to the power of 2 is equal to 4 So this 4 — is equal to the total number of little binary containers . So a picture like this is perhaps clearer: Binary bits — 00 01 10 11 Binary containers — 1 2 3 4 The total number of possible values this can create: Is directly related to the number of times each binary container [ which contains the binary bits] can be added to the front of the hashed value and to the end of the hashed value : So there this would mean there are a total of 2 to the power of 4 possible combinations 2 to the power of 4 is equal to 8 So to sum up: when thinking about bits : This is the number of bits contained within each binary container When thinking about the resulting total number of possible binary combinations: This is the total number of possible combinations and can be worked out using base 2 to the power of the desired number of bits.

What lies ahead

Visible to anyone in the world
Edited by George Muirhead, Friday, 31 Jan 2020, 13:26

I'm officially on holiday for 2 weeks from tomorrow — finally it gives me the chance to be relaxed, focused and think about all the great material I've overlooked and rushed through.

This is probably an obvious point to many people —  it's only now I'm beginning to realise why a lot of study advice keeps reiterating —take lots of short breaks, don't try to process too much information in one go.

The thoughts need to absorb your subconscious cognitive processes for one to truly understand concepts.

The differences between Classful and Classless Subnet Masks

Visible to anyone in the world

Why are  classful subnet masks of a fixed length wasteful? 

Because when you want to subnet your network,

you are constrained by doing it in powers of 2.

That is either 2,4,8,16,32,64,128 etc. 

This is one of the reasons for changing to a classless addressing scheme, this means your subnet mask can be a variable length. 

Which means your can subnet your network precisely to the required  number of required subnetworks.
