..svakako bih se složio s ovom tvrdnjom. Naime, stres odnosno jedan njegov nusprodukt inače znan kao 'paranoja' jest stanje duha i tijela u jednoj skladnoj vibraciji koja je puno više usklađena s prirodnim procesima nego uobičajeno 'mrtvo' stanje duha i tijela a na koje moderna znanost i medicina ima visoko mišljenje.
"this post is a crash course on the notation used in programming language theory ("PL theory" for short). I'll assume the reader is an experienced programmer but not an experienced mathematician or PL theorist."
Your brain often works on autopilot when it comes to grammar. That theory has been around for years, but neuroscientists have now captured elusive hard evidence that people indeed detect and process grammatical errors with no awareness of doing so.

..yes this is right, I have noticed not just that we are not making mistakes on wake up state but also when we are sleeping.
The bitcoin network speed estimate on bitcoinwatch.com passed 1 exaFLOPS (1,000 petaFLOPS) this week - over 8 times the combined speed of the top 500 supercomputers.
The bitcoin network hashrate estimate on bitcoinwatch.compassed 1 exaFLOPS (1,000 petaFLOPS) this week – over 8 times the combined speed of the top 500 supercomputers. Experts will be quick to point out that this estimate is flawed, since no FLOPS are actually used in bitcoin mining. FLOPS stands for FLoating-point Operations Per Second, and is frequently used as a standard to measure computer speed. Bitcoin mining uses an integer calculation and almost no floating-point operations, so converting bitcoin network speed to this standard is somewhat clumsy.
The FLOPS estimate is based on the opportunity cost of computers using their hardware for mining instead of other applications. Miners are using their graphics cards to perform hashes instead of other FLOPS-based distributed computing. Therefore, a conversion rate of 1 hash = 12.7K FLOP is used to estimate what this hardware could be doing.
The estimate was created in 2011, before the production of ASIC hardware that now dominates the network. ASICS are custom designed chips that can only perform bitcoin mining calculations. The exaFLOPS estimate breaks down with ASICs, because they are not capable of floating-point operations, and therefore there is no opportunity cost associated with their use.
Interestingly, the estimate may still be useful for estimating how well other supercomputers and distributed networking projects would be able to mine bitcoins. Their speed is measured in FLOPS, but they also have the capability of performing the integer operations used in hashing. What would happen if the top 10 supercomputers all switched to bitcoin mining? How much would that affect the network? Lets reverse the equation, and say that they would receive 1 hash for every 12.7k FLOP.
The fastest computer, Sequoia, would measure at about 1.6% of the bitcoin network. Their combined speed is 48 petaFLOPS, roughly equivalent to 5% of the bitcoin network. In fact, the top 500 supercomputers have a combined speed of 12% of the bitcoin network.
To actually use these computers for mining, It would take more than just installing standard mining software. But lets be honest, these computers have better things to work on like curing cancer, solving global warming, and monitoring banking transactions.
Twitter is a powerful educational social networking website that has a huge potential for teachers professional development.
Twitter is also ideal as a PLN where you get to connect with other educators from all around the globe and exchange teaching and learning materials with them. Building a PLN, however, requires making acquaintances with similar like-minded teachers and also developing your list of followers; but once you have such a solid PLN problems of maintaining it and staying updated with what others tweet become a tricky challenge.
I have curated for you some powerful tools to help you benefit the maximum from the PLN you create on Twitter. Check them out below.
Spanda is a Sanskrit term – derived from the root spadi: “to move a little” (kimcit calana) – for the subtle creative pulse of the universe as it manifests into the dynamism of living form. (...)
It might be described as the essence of a wave in the ocean of consciousness. An impulse or desire to create and enjoy, likened to an eternal spring, joyfully overflowing its inner essence into manifestation and inspiration, yet ever full, complete and unchanging. (...)
"Spanda is the pulsation of the ecstasy of the divine consciousness", as Abinahavagupta (975-1025 c.e.) defines it. When we sense this pulsation inside us, we are sensing our own personal spark of that huge, primordial life force. It is the energy behind the breath, the heartbeat, and the movement of our thoughts and feelings. It is also the source of all our inner experiences. When we get deep into ourselves, we realize that this throb, this subtle pulsation, is actually ‘meditating’ us.
Patents threaten every software developer, and the patent wars we have long feared have broken out. Software developers and software users – which in our society, is most people – need software to be free of patents.
