Why it's important to install updates on your device

<p>Ever wondered if installing updates is worth the bother? Here's what you need to know.</p> <p>Whether you use an iPad, tablet, laptop or desktop computer, you have probably been prompted at one point to update your device. While these pop-up boxes may look like the spam you see on websites, they’re far from it.</p> <p>The device you use will have an operating system built into it, so iPads or Mac laptops will operate on Apple’s iOS system while tablets and laptops not made by Apple will run on Windows. Whichever system your device uses, it will eventually need an update. While it can be easy to dismiss the update notifications when they pop up on your screen, here’s why you shouldn’t.</p> <p><strong>What’s the point?</strong> <br />When a software program is developed, it is put through tests and quality checks and only once that has been satisfied is it released to the general public. However, once the software is out there in the world, and being used in real-life environments, it can come across little issues which get reported back to the developer. These companies then fix the issues and release the solutions as software updates.</p> <p>For electronic devices, especially laptops and desktop computers, security issues can be a big problem. Software updates include security solutions to malware or hackers, as well as fixes to bugs and any other issues that have occurred since the software was released.</p> <p><strong>Is it different to an upgrade?</strong><br />While they may sound similar, a software update and an upgrade provide two different functions. An update will install a current version of your software to your device, so basically updating your existing version of iOS or Windows. On the other side of the coin is an upgrade, which allows you to upgrade a program to its next major version. Generally, there will be a cost for a software upgrade.</p> <p><strong>How do I get updates?</strong><br />If your device is connected to the internet and it detects an update is available, it will prompt you with a notification message. This will alert you to the fact that an update is available and advise you of the next steps to step, such as clicking on a button on the notification message which will start the process for you.</p> <p>In System Settings on Apple devices and Control Panel for Windows devices, there’s an option where you can turn on automatic updating. This can provide significant benefits, such as improved security and reliability.</p> <p>Ultimately, software updates exist for a reason. While they may take a little while to download and install on your device, they are worth it. So, the next time that grey box pops up on your screen saying there’s an update available, click on it. It’ll keep your tablet or laptop secure and up-to-date with your software’s latest features.</p> <p><em>Image credits: Getty Images </em></p>

Software engineer EASILY hacks airline website to find lost luggage

<p dir="ltr">A software engineer has shared just how easy it was – scarily so – for him to hack an airline’s system.</p> <p dir="ltr">Nandan Kumar was on a domestic flight on Indian airline IndiGo and revealed that he and a passenger had mistakenly taken each other’s bags. </p> <p dir="ltr">He tried calling IndiGo multiple times and was unsuccessful, so decided to put his skills to use and find whoever took his bag.</p> <p dir="ltr">Nandan shared the entire ordeal on Twitter, showing how easy it was to hack IndiGo’s website and find other passengers’ details. </p> <p dir="ltr">“I reached home when my wife pointed out that the bag seems to be different from ours as we don’t use key based locks in our bags,” he wrote.</p> <p dir="ltr">“So right after reaching home I called your customer care. After multiple calls and navigating through @IndiGo6Eand of course a lot of waiting I was able to connect to one of your customer care agents and they tried to connect me with the co-passenger. But all in vain. </p> <p dir="ltr">“Long story short, I couldn't get any resolution on the issue. And neither your customer care team was not ready to provide me with the contact details of the person citing privacy and data protection.”</p> <p dir="ltr">Nandan said customer service assured him they would call back in the morning but when they didn’t he knew it was time to “take the matter in my own hands”.</p> <p dir="ltr">“After all the failed attempts, my dev instinct kicked in and I pressed the F12 button on my computer keyboard and opened the developer console on the @IndiGo6E  website and started the whole checkin flow with network log record on.</p> <p dir="ltr">“And there in one of the network responses was the phone number and email of my co-passenger. </p> <p dir="ltr">“I made note of the details and decided to call the person and try to get the bags swapped.”</p> <p dir="ltr">Luckily the pair were not far from each other and agreed to meet at a central place to exchange the bags.</p> <p dir="ltr">Nandan, however, went one step further and urged IndiGo to update their website – as it was way too easy to hack! </p> <p dir="ltr"><em>Image: Twitter</em></p>

How does a jet engine work?

<div> <div class="copy"> <p>Modern aviation owes its success to the jet engine. The technology was originally developed in the late 1930s and early 1940s for military use in <a rel="noreferrer noopener" href="https://en.wikipedia.org/wiki/World_War_II" target="_blank">World War Two</a>, but it has since powered the passenger aircraft revolution. </p> <p>There are many different variations on the jet engine, but the one most commonly used in passenger planes is called a turbofan (because it contains a turbine and a fan). The description below is about turbofans in particular, but much of it applies more generally.</p> <h2>So how does a jet engine work?</h2> <p>At the simplest level the way a jet engine works can be reduced to just four words: suck, squeeze, bang, blow. Let’s break down what that means. </p> <h3>Suck</h3> <p>When you look at a jet engine, the first thing you will generally notice is that the front is a giant many-bladed fan, inside what is known as the intake. The blades act in exactly the same way the blades on a propeller or desk fan work, sucking air in and shoving it out the other side at high speed. The fan in a jet engine does have a lot more blades than a desk fan, though: often more than 20. Think of the fan as a propeller on steroids. </p> <p>In most modern jet engines, the fan alone can generate up to 90% of the thrust, or ‘pushing power’ of the engine. To find out where the other 10% comes from, we must continue to follow the air on its journey.</p> <h3>Squeeze</h3> <p>We are now leaving pre-jet engine technology behind. Once the fan sucks in the air, some of it is not just forced around the engine, but is funnelled to what is known as the compressor. Inside, air is pushed along by many spinning disks loaded with small blades along a tube that gets smaller and smaller. This quickly squeezes the air, making it much denser, hotter and more explosive when fuel is added.</p> <h3>Bang</h3> <p>For the pyromaniacs out there, there is where the fun begins. Fuel is added to the compressed air, creating a highly volatile mix requiring a simple spark to burn. This is what happens in the combustion chamber, where the fuel/air mix is sprayed and ignited, rapidly expanding the air and generating the rest of the thrust of the engine. </p> <h3>Blow</h3> <p>The rapid expansion of the air during combustion generates a massive amount of pressure that needs to find a way out.  The way out of a jet engine is at the end of another tube full of spinning disks bristling with blades that are spun by the force of the expanding gas. This part is known as the turbine. Once at the end of the turbine, the gases leave the engine at high speed, exerting a force on the engine in the opposite direction. (In accord with Newton’s third law: for every action, there is an equal and opposite reaction.) </p> <p>The ingenious part of the modern jet engine is that the intake fan, compressor, combustion chamber and turbine are linked by a single shaft running along the inside of the engine. So when the expanding gases spin the turbine at the back, it helps spin the fan at the front, which keeps the process going and generates more thrust.</p> <em>Image credits: Getty Images</em></div> <div id="contributors"> <p><em>This article was originally published on <a rel="noopener" href="https://cosmosmagazine.com/technology/how-does-a-jet-engine-work/" target="_blank">cosmosmagazine.com</a> and was written by Jake Port. </em></p> </div> </div>

A chemical engineer explains: What makes pepper spray so intense? And is it a tear gas?

<p>In recent weeks, the world has looked on as governments use chemical irritants to control protesters and riots. Whether it’s tear gas, pepper spray, mace or pepper balls, all have one thing in common: they’re chemical weapons.</p> <p>Chemical warfare agents have been used twice in Sydney in the past week alone. Police <a href="https://www.abc.net.au/news/2020-06-07/sydney-police-defend-pepper-spray-use-on-protesters/12330558">pepper-sprayed</a> demonstrators at Central Station, following Saturday’s major Black Lives Matter protest.</p> <p>The next day, tear gas <a href="https://www.abc.net.au/news/2020-06-08/tear-gas-fired-into-exercise-yard-of-sydney-long-bay-jail/12332572">was used</a> to break up a fight at Long Bay jail, as prison guards filled an exercise yard with tear gas canisters – also impacting nearby residents.</p> <p>These events followed the deployment of <a href="https://edition.cnn.com/2020/06/05/politics/park-police-tear-gas/index.html">chemical riot control agents</a> – specifically “pepper bombs” – in Washington DC last week. They were used to clear protesters from a public park so President Donald Trump could walk from the White House to a nearby church for a photo opportunity.</p> <p>The White House made a highlight reel to celebrate Trump’s heroic walk across the street for his bible photo op...</p> <p>US Attorney General William Barr said “<a href="https://www.factcheck.org/2020/06/the-continuing-tear-gas-debate/">there was no tear gas used</a>”, claiming “pepper spray is not a chemical irritant. It’s not chemical.”</p> <p>I’m a chemical engineer and chemist who studies chemicals in the environment. So I thought I’d clear the air about what makes pepper spray such a powerful chemical irritant, and a chemical weapon.</p> <p><strong>What’s inside pepper spray?</strong></p> <p>The active compounds in pepper spray are collectively known as capsaicinoids. They are given the military symbol OC, for “oleoresin capsicum”.</p> <p>The most important chemical in OC is capsaicin. This is derived from chilli peppers in a chemical process that dissolves and concentrates it into a liquid. Capsaicin is the same compound that makes chillies hot, but in an intense, weaponised form.</p> <p>Not all capsaicinoids are obtained naturally. One called nonivamide (also known as PAVA or pelargonic acid vanillylamide) is mostly made by humans. PAVA is an <a href="https://cot.food.gov.uk/committee/committee-on-toxicity/cotstatements/cotstatementsyrs/cotstatements2002/pavastatement">intense irritant</a> used in <a href="https://www.theguardian.com/society/2018/dec/09/pepper-spray-used-in-non-violent-situations-in-prison-pilot">artificial pepper spray</a>.</p> <p><strong>Is pepper spray a tear gas?</strong></p> <p>We’ve established pepper spray is a chemical, but is it also a kind of tear gas?</p> <p>“<a href="https://emergency.cdc.gov/agent/riotcontrol/factsheet.asp">Tear gas</a>” is an informal term and a bit of a misnomer, because it isn’t a gas. Rather, tear gas refers to any weaponised irritant used to immobilise people.</p> <p>More specifically, tear gas is often used to describe weapons that disperse their irritants in the air either as liquid aerosol droplets (such as <a href="https://www.popularmechanics.com/science/health/a28904691/how-tear-gas-works/">gas canisters</a>), or as a powder (such as pepper balls). This definition distinguishes tear gas from personal self-defence sprays which use foams, gels and liquids.</p> <p>Tear gas canisters typically contain the irritants 2-chlorobenzalmalononitrile (CS) and phenacyl chloride (CN). Both CS and CN are man-made chemicals discovered in a lab, unlike capsaicin (the traditional ingredient in pepper spray).</p> <p>But despite capsaicin coming from chilli peppers, pepper spray is still a weaponised irritant that can be delivered as an aerosol or powder. It should unequivocally be considered a type of tear gas.</p> <p><strong>Pepper spray as a weapon</strong></p> <p>The chemical irritants OC, CS and CN have military symbols because they are chemical weapons. They are termed “<a href="https://www.wbur.org/news/2020/06/10/rubber-bullets-protesters-victoria-snelgrove-boston">less-lethal</a>” because they are less likely to kill than conventional weapons. Their use, however, can still <a href="https://www.forbes.com/sites/judystone/2020/06/08/tear-gas-and-pepper-spray-can-maim-kill-and-spread-coronavirus/#47f17a2a725f">cause fatalities</a>.</p> <p>Technically, pepper spray and other tear gases are classified as lachrymatory agents. <a href="https://theconversation.com/what-is-tear-gas-139958">Lachrymatory agents</a> attack mucous membranes in the eyes and respiratory system.</p> <p>Pepper spray works almost instantly, forcing the eyes to close and flood with tears. Coupled with coughing fits and difficulty breathing, this means the targeted person is effectively <a href="https://healthland.time.com/2011/11/22/how-painful-is-pepper-spray/">blinded and incapacitated</a>. Because lachrymatory agents work on <a href="https://www.ncbi.nlm.nih.gov/books/NBK544263/">nerve receptors</a> that help us sense heat, they also induce an intense burning sensation.</p> <p>The combined effects of pepper spray can last anywhere from 15 minutes to more than an hour.</p> <p>Lachrymatory agents emerged on the <a href="https://www.history.com/this-day-in-history/germans-introduce-poison-gas">battlefields of World War I</a>. Artillery shells were filled with chemicals such as <a href="https://www.compoundchem.com/2014/05/17/chemical-warfare-ww1/">xylyl bromide and chloroacetone</a> and fired at enemy soldiers. Agents that induce choking, blistering and vomiting were added as the <a href="https://www.nytimes.com/2018/11/10/science/chemical-weapons-world-war-1-armistice.html">chemical arms race</a> escalated.</p> <p>In the 1920s, the <a href="https://www.un.org/disarmament/wmd/bio/1925-geneva-protocol/">Geneva Protocol</a> was enacted to ban the use of indiscriminate and often ineffective chemical weapons on the battlefield. Today, the unjustified use of chemical riot control agents <a href="https://www.aljazeera.com/indepth/opinion/2012/04/201242913130963418.html">threatens to erode</a> the systems that are meant to protect us from the most dangerous weaponised chemicals.</p> <p><em>Written by Gabriel da Silva.

Police accused of lying about use of “ineffective” facial recognition software

<p>An <a href="https://www.buzzfeed.com/hannahryan/clearview-ai-australia-police">online tech news source</a> recently ran a story detailing a data breach at controversial facial recognition company Clearview AI, which exposed its entire client list.</p> <p>According to the report, the list includes four Australian police organisations, comprising the Queensland Police Service, Victoria Police, South Australia Police and the Australian Federal Police.</p> <p>The leaked client list suggests that police officers have used the highly inaccurate technology in an attempt to ‘identify’ around 1000 suspects in Australia – a process which has been <a href="https://www.sydneycriminallawyers.com.au/blog/queenslands-facial-recognition-regime-a-complete-failure/">proven over and over again</a> to lead to <a href="https://www.sydneycriminallawyers.com.au/blog/facial-recognition-database-could-lead-to-wrongful-arrests/">the false identification and arrest of innocent persons</a>.</p> <p>Indeed, a previous trial of facial recognition technology in Queensland was ruled a ‘<a href="https://www.sydneycriminallawyers.com.au/blog/queenslands-facial-recognition-regime-a-complete-failure/">complete failure</a>’ – with the software misidentifying people the ‘vast majority’ of cases – and a trial in the United Kingdom in 2016/17 got it wrong in 98% of cases.</p> <p>Police had previously denied using the Clearview AI software and, despite the leak, have continued to do so – with the South Australian Police Force issuing a statement which asserts that its officers have not been using it.</p> <p>Queensland has been slightly more forthcoming, saying that facial recognition technology is one of ‘many capabilities’ available to its officers.</p> <p>Victoria Police claims the software has not been used in any ‘official capacity’, which begs the question as to why police organisations would spend large amounts of taxpayer dollars on purchase and licensing.</p> <p>The AFP has remained silent.</p> <p>Clearview AI’s programme has attracted an enormous amount of controversy worldwide, being variously labelled as ‘ineffective’, ‘wasteful’, a ‘gross breach of privacy’ and a ‘honeypot for hackers’.</p> <p>The Clearview database contains billions of images amassed from sources such as Facebook, Instagram, LinkedIn and other public websites, and the application of the software has the potential to lead to wrongful arrests, whereby innocent persons are wrongly matched to suspected offenders.</p> <p>The reports regarding the leaked client list have heightened concerns that ill-intentioned hackers will gain access to a wealth of private information and use it to engage in criminal conduct such as <a href="https://www.sydneycriminallawyers.com.au/blog/the-rising-cost-of-identity-crime-in-australia/">identity theft</a>.</p> <p><strong>Privacy laws</strong></p> <p>Under current Australian privacy laws, biometric information, that is your face, fingerprints, eyes, palm, and voice is considered sensitive information.</p> <p>The <a href="https://www.legislation.gov.au/Details/C2014C00076">Privacy Act 1988</a> (Cth) makes clear that any organisation or agency collecting this ‘sensitive’ information must first obtain consent to do so.</p> <p>However, there are exceptions to this general rule including where the information is “necessary” to prevent a serious threat to the life, health or safety of any individual.</p> <p>It’s an exception many believe has been exploited by law enforcement agencies, with legal commentators suggesting it is not broad enough to encompass all of the conduct that police have been engaging in.</p> <p><strong>National surveillance</strong></p> <p>Red flags were raised last year when the Federal Government announced plans to <a href="https://www.sydneycriminallawyers.com.au/blog/australias-future-is-nationwide-facial-recognition-surveillance/">create a national facial recognition database</a> by collecting photos from drivers’ licences and passports.</p> <p>The government justified the implementation of the database, by saying that it would both help to combat identity theft <a href="https://www.sydneycriminallawyers.com.au/blog/the-rising-cost-of-identity-crime-in-australia/">(which is on the rise)</a> as well as be a useful tool for protecting national security, because the database would be made available to law enforcement agencies too.</p> <p>The legislation presently before parliament allows both government agencies and private businesses to access facial IDs held by state and territory traffic authorities, and passport photos held by the foreign affairs department.</p> <p>The legislation is currently stalled because of concerns about privacy implications and lack of safeguards in the proposed law.</p> <p>But most state and territory governments have already updated their driver’s licence laws in anticipation of the database after an agreement at the Council of Australian Governments in October 2017. If you’re applying for, or renewing a passport, then you are required to sign a consent form.</p> <p><strong>Facial recognition AI is unreliable</strong></p> <p>One of the most significant concerns is that AI technology is still unreliable – the benefits don’t outweigh the massive intrusion into our personal privacy. Plus, there are inherent problems with the current technology. False positives are a major issue.</p> <p>In 2016 and 2017, London’s Metropolitan Police used automated facial recognition in trials and reported that more than 98% of cases, innocent members of the public were matched to suspected criminals.</p> <p>Despite these concerns, the Home Affairs Department is impatient to implement the technology and says that facial recognition experts (humans) will work with the technology to provide more accurate outcomes.</p> <p>But that’s of cold comfort to anyone concerned about their privacy. <a href="https://www.sydneycriminallawyers.com.au/blog/welcome-to-1984-the-governments-relentless-assault-on-democracy/">Because, as is already the case in China</a>, facial recognition can be used for mass surveillance.</p> <p>And, we’ve already seen many examples of how data breaches can occur even with appropriate legislation in place.</p> <p><strong>Data breaches in government departments</strong></p> <p>Last year, information came to light showing that <a href="https://www.sydneycriminallawyers.com.au/blog/dozens-of-breaches-of-the-my-health-record-database-have-already-been-recorded/">data breaches of the My Health Record</a> database rose from 35 to 42 in the past financial year, despite consistent claims by the federal government that the database is safe and secure, and that the privacy of those who choose not to opt out is protected.</p> <p>In 2018, the South Australian government was forced to shut down guest access to its online land titles registry, after an unidentified overseas ‘guest user’ was able to download the personal details of more than a million Australian home owners, information that could potentially be used to develop a false identity.</p> <p>Police forces and other government organisations have repeatedly failed to <a href="https://www.sydneycriminallawyers.com.au/blog/police-officers-misuse-private-information-for-personal-gain/">properly secure confidential information</a> of members of the public, and some rogue police officers have <a href="https://www.sydneycriminallawyers.com.au/blog/police-officer-jokes-about-giving-victims-address-to-abusive-partner/">broken the law by releasing sensitive information</a>, putting vulnerable individuals in danger.</p> <p>Right now, the fact that Australian police forces exist on Clearview AI’s client list, and they’re not forthcoming about it should also set alarm bells ringing for all Australians.</p> <p>The Office of the Australian Information Commissioner (OAIC) has launched an inquiry into whether the software is being employed in Australia, or if its database contains information on Australians. The commission’s final report will no doubt reveal all.</p> <p><em>Written by Sonia Hickey.

Pilot says plane engines cut out on most flights

<p>If you’re a nervous flyer, odds are you’ve already has visions that have revolved around your airplane’s engines cutting out mid-flight followed by some nightmarish descent.</p> <p>But what if we were to tell you engines cut out on most routine flights?</p> <p>The prospect of sitting in an airplane that’s 30,000 feet in the air and doesn’t have its engines on is one that’s daunting to consider (especially if you don’t have a degree in civil aviation) but most modern aircraft are designed to glide.</p> <p>Even mega-jumbo jets can glide for extreme distances. If you’re sitting in the cabin and it sounds as though the engines have been turned off, it’s because they have.</p> <p>Aviation expert Patrick Smith told <a href="http://www.news.com.au/" target="_blank"><span style="text-decoration: underline;"><em><strong>News.com.au</strong></em></span></a>, “It’s not the least bit uncommon for jets to descend at what a pilot calls ‘flight idle,’ with the engines run back to a zero-thrust condition,” he wrote.</p> <p>“They’re still operating and powering crucial systems, but providing no push. You’ve been gliding many times without knowing it. It happens on just about every flight.</p> <p>“Obviously an idle-thrust glide is different from the engines quitting outright, but even then, the glide itself would be no different.”</p> <p>Were you aware of this? Are you a nervous flyer?</p>

You’ll soon be able to pay for things using facial recognition software

<p>Forget your PIN. Throw away that pen, because signing is a thing of the past. The new way to pay for things by credit card is the selfie. Yes, you read that correctly – you’ll soon be able to pay for your purchases using facial recognition software, MasterCard announced last week.</p> <p>The technology, created by MasterCard in a partnership with tech giants Google, Apple, and Samsung, will digitise one’s face into a series of ones and zeros, convert that series into a hash, and then compare that with one stored on the MasterCard servers. If all of that sounds a little complex, don’t worry – it’s confused us as well. All we know is that people far cleverer than us have come up with a fancy way to use technology.</p> <p>The technology will be used through an app on smartphones, which is activated with a fingerprint, or by staring at one’s phone and blinking once – a trick used to prevent people using a photo to hoodwink the system.</p> <p>MasterCard have revealed that they won’t have access to the photos, as it will be converted to the hash (see: the confusing process one paragraph above) to be stored in their database – they’ll never be able to recreate your face using the stored information.</p> <p>A test with 500 cardholders is expected to begin soon, with plans to launch the technology worldwide next year.</p> <p><strong>Related links:</strong></p> <p><span style="text-decoration: underline;"><strong><em><a href="/news/news/2015/07/cash-dead-in-decade/">Will cash be dead in a decade?</a></em></strong></span></p> <p><span style="text-decoration: underline;"><strong><em><a href="/news/news/2015/07/worlds-most-liveable-cities/">The world's most liveable cities revealed</a></em></strong></span></p> <p><span style="text-decoration: underline;"><strong><em><a href="/news/news/2015/07/dolls-with-disabilities/">These dolls with disabilities are flying off the shelves</a></em></strong></span></p>
