![]() There are also web tools like the ones I used to check my student essay, like Copyleaks, Sapling, and Winston AI, or others like GPTZero and the " AI classifier" released by OpenAI, the creator of ChatGPT. Its CEO Chris Caren told me that the software's false positive rate (when it wrongly identifies human-written text as AI) stands at 1%. For example, Turnitin, a plagiarism prevention software company that is used by educational institutions, released AI writing detection in April. In the case of student cheating, the reassuring news is that teachers and educators already have existing tools and strategies that could help them check essays. However, as I would soon discover, the problem of AI fakery spans beyond the world of education – and technology alone won't be enough to respond to this change. So, how might we spot the AI cheaters? Could there be cues and tells? Fortunately, new tools are emerging. As a mother to a young eight-year-old child with a whole lot of educational journey still before her, seeing AI used by a school-child caused me great concern about the integrity and value of the learning process in the future. Staring at the fake student essay before me, I couldn't help but worry. What struck me was the possibility that the intentional use of AI could be more widespread than I had realised. Of course, students trying to cheat isn't anything new. Yet here I was, caught by surprise because a student thought it would be acceptable to submit an AI-drafted entry for a writing competition. I had known for some time that AI-written content was causing serious challenges to many industries, including my own profession of journalism. ![]() Four separate AI detection softwares all had one clear message: this is an AI cheater. So then I ran it through yet another software called Winston AI. A third confirmed the first two, but was slightly lower in its scoring: 89% AI. ![]() I needed to be sure, so I ran it through another tool: Sapling, which identified 96.1% non-human text. Within seconds, Copyleaks displayed the result on my screen and it was deeply disappointing: 95.9% of the text was likely AI-generated. I ran the essay through AI detection software. ![]() I was judging a science-writing competition for 14-16 year-olds, but in this particular essay, there was a sophistication in the language that seemed unlikely from a teenager. As I read on, however, my alarm bells started to ring. I don't know what exactly struck me about these two words, but they caused me to pause for a moment. ![]()

Popshot is a beautifully illustrated magazine that publishes short stories, flash fiction and poetry from the literary new blood. The other idea I wanted to bring forward was the idea that Plinio had been wandering for quite some time and a significant distance. I really wanted to emphasis a sort of creepy underlighting which cast shadows unnaturally and really brought out the sense of beauty and doom looming around the character. WIth the sketch in place, it was time for the fun part: shaping and coloring! While I liked both sketches, Sketch 1 turned out to be the best fit with the mood of the story as it placed significant emphasis on the scale of the environment Plinio was battling through. Here is the sketch I did before our family emergency as I was trying to get the idea recorded as soon as possible: As much as this was an illustration of Plinio, I realized it was also a self portrait which encapsulated my journey as a husband and father into the unknown. When I was able to get back into the drawing saddle, I ended up channeling all the frustration, fear, and emotions I was experiencing into the illustration. PopShot's creator, Jacob Denno was very understanding and accommodating as I worked to get things situated at home. ![]() Thankfully, my wife and son are doing great. For those of you who may not know, that's a very serious situation! Just as I was putting down sketches for this assignment, my wife ended up in the hospital and delivered our son 8 weeks before his due date. Unfortunately, real life doesn't always cooperate with our best made plans. The allure of drawing fantasy was what drew me out of a decade long stint as a designer so all this to say, I was pumped! Not only was the magazine's theme great, the story I was working with would afford me the opportunity to draw a moody fantasy setting.

Escrito por Mila Yanovska In case anyone is unaware of the Voynich manuscript or its significance, it is a document that has been carbon-dated to the early 15th century which has long baffled scholars. In June 1921, the monthly magazine Hearst’s International announced that University of Pennsylvania Professor William Newbold had “come upon the key to the secret cipher of the Manuscript … and the truth of six hundred years ago is coming out!” Newbold surmised that 13th-century English scientist Roger Bacon had written the manuscript with the aid of a microscope and a telescope, centuries before the invention of either instrument. The Voynich manuscript is an illustrated codex, hand-written in an unknown script referred to as 'Voynichese'. (Image credit: Beinecke Rare Book and Manuscript Library, Yale. For centuries, the Voynich Manuscript has resisted interpretation, which hasn’t stopped a host of would-be readers from claiming they’ve solved it. And last week, a hullaballoo erupted over a Times Literary Supplement piece by historical researcher and television writer Nicholas Gibbs, who claimed to have solved the enduring Voynich mystery. The Voynich manuscripts unintelligible writings and strange illustrations have defied every attempt at understanding their meaning.

For hundreds of years, this 15th-century. An emotional investment in the Voynich manuscript offers little in the way of return. "I don't think there's much chance that the Voynich manuscript is simply an unidentified language, because there are too many features in its text that are very different from anything found in any real language." The manuscript is currently held at Yale University. "It's been accepted for decades that the statistical properties of Voynichese are similar, but not identical, to those of real languages," Gordon Rugg, a researcher from Keele University, told the BBC. Some academics brushed off the findings, saying they're still convinced the manuscript is simply a hoax, not a lost language or an undecipherable code. "While the mystery of origins and meaning of the text still remain to be solved, the accumulated evidence about organization at different levels, limits severely the scope of the hoax hypothesis and suggests the presence of a genuine linguistic structure," Montemurro and Zanette concluded. ![]() ![]() ![]() In this tutorial, I will explain how to set up your Electroneum mining rig.

In Brief, Electroneum coin has a lot of similarities with Bitcoin, though it is based on its own blockchain.

Its team of developers is rather impressive.It can be stored both on the cloud and in offline wallets.Its transaction speed and security are as good as Bitcoin’s (and some even claim that Electroneum is safer than Bitcoin).Here are some of its already existent features worth mentioning: In my opinion, Electroneum has got what it takes to soon be considered a viable Bitcoin alternative. Its main aim is to become a Bitcoin alternative with a couple of improvements, as well as a user-friendly platform where everyone can mine, trade and transfer the tokens without the need to have any prior tech knowledge.

He dismisses modern monetary theory as failing to explain inflation or the hyperinflation theory of cryptocurrency enthusiasts. Smith claims that mainstream economic policy has worked. But right now, ‘core’ inflation remains close to 5% a year. He bases this on measuring inflation rates in the most inflationary sectors. Smith claims that the 2% inflation target will soon be met in the US. Take Noah Smith, a prolific mainstream economics blogger. Now the situation is in reverse.ĭespite the abject failure of monetary policy to affect inflation rates, mainstream economics continues to claim that it does and there is no alternative to raising interest rates. Instead, there was credit-fuelled boom in stock and bond prices. Despite huge dollops of money injection (quantitative easing) and zero interest rates, price inflation refused to reach the 2% targets in the major economies (and shas not succeeded in Japan now). This is the current policy of the Bank of Japan. I am reminded by the claim by central banks back in the 2010s that they needed to keep interest rates near zero or even below in order to boost ‘demand’ and avoid inflation going under 2% or even into deflation. In short, central banks continue to hike interest rates despite the failure of this policy to have any significant effect on the prices of goods and services, despite claims to the contrary. But the pace of reduction is likely to slow because so-called ‘core’ inflation rates, which exclude food and energy, and in effect measure ‘underlying’ or ‘domestic’ inflation of prices in an economy, have remained ‘sticky’, i.e well above the 2%. The IMF reckons that global inflation will drop 6% a year now to 4% a year, but not until the end of 2024. The US inflation rate has fallen back to 3% a year and Spain’s even below 2%. Yes, so-called headline inflation has been falling fast as food and energy supply improved and prices for these essentials dropped back. At his press conference this week, Fed chair Powell said that the Fed’s 2% target would not be reached before 2025! It is more likely that the US economy will have been driven into a slump before then. Despite the huge rise in interest rates, and with more to come, consumer price inflation is still not back to anywhere near 2% a year. There was no ‘wage-price ‘ spiral as the central bankers claimed as one reason why interest rates had to rise on the contrary, it was profit-price spiral.īut here is the rub. We now know that it was profits that made the largest contribution to price rises in the last two years, not wages. In addition, the Russian invasion of Ukraine added another accelerator to price rises. In addition, multi-national food and energy producers took advantage of the supply blockages to raise prices and increase profits (and to some extent, lever up their ‘mark-ups’ on costs). As a result, in particular, basic commodities (food and energy) rose sharply in price, driving up import prices for most countries. And yet the evidence on the causes of the inflationary spike since the end of the pandemic slump clearly shows that it was a supply ‘shock’ (the word used by the mainstream to describe anything disturbing the supposed harmony of supply and demand in a market economy).Īfter the pandemic, global production was slow to recover as healthy labour was in short supply and international trade and transport was clogged with obstacles. The latter side of the price equation is ignored. ![]() It assumes that the cause of inflation is excessive demand and not insufficient supply. ![]() So raising interest rates, by increasing the cost of borrowing (mortgages, consumer credit and loans to firms), will slow down spending and investment sufficiently to bring ‘demand’ back into line with ‘supply’.Īs I and many others have argued, this theory is full of holes. This policy is based on the theory that accelerating inflation was being caused by ‘excessive demand’ by consumers (workers). ![]() The ostensible reason for this is that hiking interest rates until the pips squeak in the economic orange will eventually get the inflation rate of consumer prices down to the (arbitrary) central bank targets of 2% a year. The Fed rate now stands at its highest in 22 years. Both the Federal Reserve and the European Central Bank raised their policy interest rate again this week. ![]() ![]() ![]() Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types.

The parsec (symbol pc) is a unit of length used in astronomy. The International Astronomical Union recommends "au" and international standard ISO 31-1 uses "AU". The symbol "ua" is recommended by the Bureau International des Poids et Mesures, but in the United States and other anglophone countries the reverse usage is more common. The currently accepted value of the AU is 149 597 870 691 ± 30 metres (about 150 million kilometres or 93 million miles). It is approximately equal to the mean distance between the Earth and Sun.

The relation between a parsec and a light year is established because far objects in space are measured in light years. The term arcsecond refers to the angle measurement, and an arc is used because of the Earth's movement around the Sun in a particular orbit. In other simple terms, a single parsec can be conceived to be the distance to a celestial object whose apparent position changes by one arc second from one point of the Earth's orbit to another point. The difference between the position of the apparent location from its original location is measured using an angle which is formed if we observe two lines of sight that form a triangle in the orbits of the Earth, and we call this parallax angle or Parsec angle. A light year is defined as the distance light takes to travel in one year of Earth. The concept of Parsecs and light years comes from the branch of physics known as astronomy. In order to find the relationship between a parsec and a light year, we need to familiarise ourselves with other terms as well. Additionally, the use of parsecs allows for more precise measurements and calculations, as it takes into account the curvature of space and the distortions caused by the presence of other massive objects. The size of a parsec is based on the Earth's orbit around the Sun, which makes it a well-defined and universal unit of measurement.īy using parsecs, astronomers can compare the distances between stars and other celestial objects more easily, as well as calculate the sizes of galaxies and other large structures in the universe. It is possible that when we view a particular star in the night sky, the Earth will be located at one position, which is from one specific side of the Sun's orbit, and when we view it again after some time period is passed, the same star may be appearing elsewhere due to the continuous revolving motion of Earth in the orbit of the Sun.ĭue to this fact we use parsecs in astronomy as It provides a convenient and standard way to describe large distances within our galaxy and beyond. This effect is similar to an illusion in which our viewpoint changes over a period of time due to the constant revolving motion of the Earth. This motion varies constantly with respect to time, because of which a parallax error happens in which the nearby objects seem to appear more distant from their actual position. ![]() For observations from the Earth’s surface, turbulence in the Earth’s atmosphere causes point sources (such as stars) to be smeared. As we know, the planet Earth rotates in a constant motion and also revolves around the Sun. An arcsecond (denoted by the symbol ) is an anglular measurement equal to 1/3600 of a degree or 1/60 of an arcminute. ![]() ![]() ![]() The first tool we'll install is Karabiner-Elements. ![]() There are two primary tools, plus a third companion tool, that we will install in order to map our Cmd+P combo to Cmd+K within Slack–and while we're at it, we'll be providing a foundation to build an entire system of custom keyboard shortcut mappings for any app. Let's take a look at how we can accomplish this. So I just need a way of converting the Cmd+P combo I have already memorized into the Cmd+K combo Slack expects. However, until a recent update, Slack’s quick open palette, triggered with Cmd+K, had no way to override it in a setting or menu.Īs described above, the ideal scenario would be one where I could always use the same keyboard shortcuts to do the same things in all of my apps. Over time, I've noticed other apps also offer similar quick open palettes. With this palette, I can trigger this shortcut and just type the name (or partial name) of something I want to open without needing to navigate the interface. Command+P EverywhereĪs a long time Sublime Text user, I couldn't imagine life without ST's Quick Open Palette, which is triggered with Cmd+P. We are going to learn how to train our keyboards to map the key combos you want to use to the key combos the apps on your computer expects. And some apps provide keyboard shortcuts without offering any way to override them, or worse, don't even offer keyboard shortcuts at all. Many other apps expose shortcuts through menus that can be overridden at the system level, but this gets tedious if you you have more than a few shortcuts you want to override. The apps that are easiest to customize explicitly allow users to declare keyboard shortcuts in the settings. It may require extra research to apply these principles to non-Mac computers. Tools do exist to accomplish the same results on other operating systems. Note for Windows and Linux users: While the principles outlined here are universal, the tools are Mac only. We'll start by learning how to install and configure the required apps, then, later on, I'll introduce the system of keyboard shortcut organization I use every day. We are going to walk through creating a system to bring uniformity to our apps with a single set of keyboard shortcuts. What if you could eliminate that switching cost? What if switching apps, rather than forcing you to learn new shortcuts, instead reinforced your muscle memory for the shortcuts you already know? In short, what if all of your apps felt the same? So, what happens when you try out a new app, and its keyboard shortcuts don’t align with your muscle memory? You could work on memorizing a whole new set of shortcuts, but then you face a cost of switching every time you change apps. You've likely memorized many of the shortcuts of your most used apps and, somewhere during this process, repetition has given way to muscle memory, making these shortcuts feel like second nature. But you're probably also aware that most of the apps you use on a daily basis provide keyboard shortcuts to increase the efficiency of routine tasks. ![]() You likely use a combination of your mouse and keyboard to interact with your computer throughout the day. ![]() If you’re reading this, odds are you work on a computer. ![]() |
