'If you’re a hacker (as in hack stuff together)/developer type, then chances are you already know about and likely own a Raspberry Pi.For those that don’t, it’s a seriously cheap, ultra flexible computing platform that just grew up dramatically with it’s 4th edition.The Raspberry Pi 4 Model B comes with some seriously impressive specs, here’s the highlights: A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU ( ~3 × performance ) 1GB, 2GB, or 4GB of LPDDR4 SDRAM Full-throughput Gigabit Ethernet Dual-band 802.11ac wireless networking Bluetooth 5.0 Two USB 3.0 and two USB 2.0 ports Dual monitor support , at resolutions up to 4K VideoCore VI graphics, supporting OpenGL ES 3.x 4Kp60 hardware decode of HEVC video Complete compatibility with earlier Raspberry Pi products The device comes in 3 memory options, starting at 1GB for the entry level price of US$35, while 2GB will set you back US$45.The most expensive (still a bargain) is the 4GB version at US$55.If you want to get the details on just how much faster the Raspberry Pi 4 is, then they’ve conveniently published benchmarks you can review right here . Naturally if you want to ship one over to Australia, you’ll pay a little extra for shipping and taxes, but you get the idea, this computer is crazy cheap.It’s also very different than most computers in that it is BYO almost everything.This computer is designed for such a diverse range of applications, that you decide which case it goes in.By the way, old Raspberry Pi cases don’t fit due to some of the modules being moved.Some other important changes to the architecture of Raspberry Pi 4 are the change to USB-C power.As many of us now have plenty of USB chargers around, this is incredibly convenient and much appreciated.There’s also no full-sized HDMI connector.At first you may find that annoying, but they made compromise to it 2x mini HDMI connectors, enabling dual-4K display support at 30fps. amazing from such a cheap computer.There’s Gigabit Ethernet if your idea requires super-fast network throughput, along with a couple of USB 3.0 ports.Raspberry Pi 4 Computer Desktop Kit One of my favourite accessories is the Raspberry Pi 4 Computer Desktop Kit.This includes a Raspberry Pi 4 with 4GB RAM, a USB keyboard (with hub) and mouse, SD card, USB-C power supply, Micro HDMI cable and a case for your Pi.That really is a one stop shop for a insanely cheap computer.Basically add a monitor and you’re done.Price and Availability There are 2 places you can buy from if you’re an enthusiastic Aussie, the first is Core Electronics , or from PiAustralia . In terms of availability, it seems the 1GB model is available now, while the 2 and 4GB variants are on pre-order with an availability from July 1st.In Australia, the prices are: 1GB – A$59.95 2GB – A$66.95 4GB – A$94.95 About the only negative of having such a powerful piece of hardware is that it still can’t run Windows 10.Given the specs, that’s kind of strange, but it’s confirmed in the FAQ section of the Raspberry Pi Australia site.So what can you run on it?The answer, Linux.If you don’t want to run the Raspberry Pi Desktop, you can select from installs like Ubuntu, Windows 10 IoT Core and a number of others.Regardless of the number of uses you can find, perhaps one of the biggest benefits of having such a low-cost computer is that you can give it to kids to learn to program with . A lot of programming is simply software based, but those looking to find more practical applications for programming may look to a hardware/software combination, powered by Raspberry Pi 4. .

'Educating our young Australians about the risks they’ll face online is important, but so is offering them the opportunity to learn about cyber security at a deep level.The Australian Computing Academy (ACA), this week launched the Schools Cyber Security Challenges (Cyber Challenges) in Western Australia.The new $1.3 million national program will see a cybersecurity curriculum taught to Australian students in years 7-10 for the first time.As kids learn about computers, there’s always the risk that they’ll fall into the dark parts of the internet, like they could fall into the dark parts of society if they mix with the wrong social circles.One of the best strategies to fight against this is to offer student a window into a cyber security career, one that helps our country fight global challenges.Careers in this area are some of the highest paid as they demand technical excellence and a serious attention to detail, as well as creativity in responding to the ever changing threat actors.This will benefit the industry as a whole by increasing the number of people coming through the ranks and protecting both enterprises and Government in WA.According to AustCyber, Australia will need 18,000 more cybersecurity workers by the year 2026, making it critical for Australia’s economic prosperity to build a highly skilled and educated cybersecurity workforce.The Schools Cyber Security Challenges are now available in WA High Schools and have been developed to showcase a positive collaboration between government, industry and the education sector.They are delivered free and come with classroom-ready student and teacher resources designed to promote cybersecurity skills.The materials are fully aligned with the Western Australian Curriculum: Digital Technologies and the ICT Capability.Below is an example of the diverse resources available in the curriculum.The launch event included an expert panel discussion with industry leaders discussing the importance of cyber security skills development in schools and the role education must play in the future of this emerging capability of our students and teachers.Panel members from left to right: Ian Martinus, AustCyber WA Node Director, Peter Bouhlas, WA Government CISO, Professor Craig Valli, ECU Security Research Institute, Volker Rath, BT Head of Security Consulting Australasia, Martha McKeen, CBA Senior Manager Cyber Security Engagements and Skills Development The Schools Cyber Security Challenges have some big partners including ANZ, NAB, Commonwealth Bank, Westpac, BT and AustCyber.More information available at here . .

With the number of pest and disease threats that could enter our country rapidly growing, biosecurity champions from across Australia, New Zealand, Canada and Mexico came together to form Australia’s first biosecurity collective.
'With the number of pest and disease threats that could enter our country rapidly growing, biosecurity champions from across Australia, New Zealand, Canada and Mexico came together to form Australia’s first biosecurity collective.The inaugural Australian Biosecurity Symposium , co-hosted by Animal Health Australia (AHA), the Invasive Species Council (ISC) and the Centre for Invasive Species Solutions (CISS), saw almost 400 delegates converge on the Gold Coast to discuss how we can future-proof our biosecurity system to better protect our multi-billion agricultural industry, our iconic native plants and animals and our people.Andreas Glanznig, CEO of CISS, said we need to double down on smarter actions to future proof Australia’s biosecurity system. “By 2030 Australia will see a doubling of international passenger arrivals and containerised cargo traffic will increase 170% to 2032.We need to work more collaboratively and smarter, with more efficient systems to keep future pests and diseases out. “Prevention is a key part of the solution and new techniques like environmental DNA surveillance, drone detection using thermal regulation, artificial intelligence and recognition are just some of the new innovations on the horizon which could be game changers for the biosecurity system if we strengthen efforts now,” Mr Glanznig said.Kathleen Plowman, CEO of AHA, called for the development of a national biosecurity strategy and a long term sustainable biosecurity investment plan, as well as a national biosecurity partnership agreement, to mobilise all of Australian society. “Biosecurity prevention is a shared responsibility but without a shared vision and authority it is difficult to bring everyone along for the ride. “We need clear signposts along the way, we need to plot our journey and we need to make sure we are all on the same path, to ensure the system is well-equipped for the future,” Ms Plowman said.Andrew Cox, CEO of ISC, wants to rally the community together and start a biosecurity movement. “We want biosecurity to be top of mind and top of importance for all Australians, like the Landcare movement has been since it was formed in the 1990s. “There is growing awareness of biosecurity and now we want to take it further and build a mass movement of biosecurity champions across the country who take ownership of the problem and help keep our country free of new weeds, pests and diseases,” Mr Cox said.The 2nd Australian Biosecurity Symposium will be held in 2021 with a workshop to be held in 2020 to progress key outcomes from 2019’s Symposium.For more information and updates visit www.biosym.com.au More from the Centre for Invasive Species Solutions .

'Powered by Blockchain, Libra is a new open source digital currency that aims to be the first truly global currency.In the age of the internet, we can transact with people across the world, but there’s a couple of barriers, the first which is language, but thanks to computer translation, that’s largely solved and the other is money.If you’re not familiar with it, Blockchain is a technology that can safely store transaction records on a peer-to-peer network instead of storing them in a single location.Independent servers around the world, called nodes, make up the network that operates the blockchain.The most famous example of a cryptocurrency built on blockchain technology is Bitcoin.If Libra is successful in its mission to be a global currency, Bitcoin will feel like pocket change.Internationally, the United Nations currently recognises 180 currencies used across 195 countries.Every time you want to trade goods and services to someone in another state or country, you are often hit with taxes and conversion fees.This could all be a thing of the past if Libra takes off.While our financial institutions have been around for decades, they’re actually still really immature.It often takes days to execute a transaction, its often inconvenient to change from one format to another and give someone money often requires multiple pieces of information.Even today, an estimated 85% of transactions use cash.A staggering 31% of the global population (or 1.7Billion people) don’t have money in banks.These factors combined mean there’s serious room for improvement.We are joining Libra in the hope of bringing the value of blockchains to billions of people across the world.In this day and age, we should be able to send money as quickly and securely across borders as we send photos and email.What’s more, the opensource nature of the project will allow developers around the world to build on top of it permissionlessly.We look forward to working with Libra to build a more decentralized and inclusive financial system.Katie Haun, General Partner, Andreessen Horowitz Libra is a new cryptocurrency that aims to be fast, secure, scalable and mobile, meaning anyone with an entry-level smartphone and above can get involved.As with all Crypto, the first step to launch is to release a whitepaper detailing how your currency works.You can read the full 12 page PDF here , but the most important point is that this is really a threat to banks, leaving behind financial legacies from the past, instead of recognising how we need currency to be transacted in the 21st century.While many have seen the launch, promoted by Mark Zuckerberg as a Facebook cyrptocurrency, in reality, Libra is created and operated by the Libra Association.This consists of geographically distributed and diverse businesses, nonprofit and multilateral organizations, and academic institutions.Coinbase is committed to its mission of creating an open financial system for the world.A key element of that vision is introducing crypto to a much broader audience.We’re pleased to be a Founding Member of the Libra Association because we believe this project has the potential to massively increase the awareness of crypto on a global scale.Emilie Choi, Chief Operating Officer, Coinbase, Inc.The initial group of organizations that will work together on finalising the association’s charter and become “Founding Members” upon its completion.The list below includes some interesting names, like PayPal and Stripe, Mastercard and Visa that could have been superseded by Libra, but have instead decided to integrate instead, smart.By industry, here’s the current list of Libra founding members.Payments : Mastercard, PayPal, PayU (Naspers’ fintech arm), Stripe, Visa Technology and marketplaces : Booking Holdings, eBay, Facebook/Calibra, Farfetch, Lyft, Mercado Pago, Spotify AB, Uber Technologies, Inc.Telecommunications : Iliad, Vodafone Group Blockchain : Anchorage, Bison Trails, Coinbase, Inc., Xapo Holdings Limited Venture Capital : Andreessen Horowitz, Breakthrough Initiatives, Ribbit Capital, Thrive Capital, Union Square Ventures Nonprofit and multilateral organizations, and academic institutions : Creative Destruction Lab, Kiva, Mercy Corps, Women’s World Banking All of this is built on decentralized blockchain technology.This means it’s not run by just one organisation, in theory, making the system fairer overall.Secured by cryptography, if implemented correctly, will also make it the safest currency to transact in while being accepted in the most places online.So when can you start using Libra?The answer is, not for a while.Zuckerberg says there’s still a lot more to learn and do before Libra will be ready to officially launch.Libra holds the potential to provide billions of people around the world with access to a more inclusive, more open financial ecosystem.We look forward to participating in the Libra network as a Founding Member, as well as through providing our community with access to Libra through Calibra.We know the journey is just beginning, but together we can achieve Libra’s mission to create a simple global currency and financial infrastructure that will empower billions of people.David Marcus, Head of Calibra, Facebook Creating a global company is hard enough, but creating a global currency has never been done before, it’s a major undertaking.The association has been working with policymakers and experts in areas like financial inclusion, economics, security, privacy and blockchain, but the road ahead is a long one.Announcing Libra publicly is the first step, ahead of nailing the technology, the security and the implementation to make it quick, easy and simple for users.Ensuring Governments don’t just outright ban something they don’t understand will also be a challenge across the world.At PayPal, we believe in democratizing participation in the digital economy for people from all walks of life and businesses of all sizes.PayPal is pleased to join other leading technology and financial services organizations to form Libra, with the goal of exploring a new, global digital currency, built on blockchain technology.Dan Schulman, President and CEO, PayPal You should follow Libra on their social channels below: Facebook Twitter Instagram If you’re a developer or just a technical type, then

Australia is leading the charge towards greener and safer gold production with an environmentally-superior alternative gold recovery process technology, dispensing with toxic cyanide and mercury currently used in most gold production processes
'Australia is leading the charge towards greener and safer gold production with an environmentally-superior alternative gold recovery process technology, dispensing with toxic cyanide and mercury currently used in most gold production processes worldwide.On the back of successful industry trials and the first gold pour in 2018, Australia’s national science agency, CSIRO, will transfer its ‘Going for Gold’ process technology to Australian company, Clean Mining Limited.CSIRO Research Program Leader, Dr Chris Vernon, believes the technology not only overcomes a significant environmental hazard, it also opens the door for Australian and international gold miners and end users to capitalise on demand for sustainable processes and products. “Cyanide is used in about 75 per cent of global gold production, and while the industry works to manage the associated risks, there have been recent toxic spills overseas that have caused great concern to communities,” Dr Vernon said. “Developing an alternative process, which eliminates hazardous chemicals while maximising gold recovery, meets industry and consumer demands for more sustainably-produced gold.” The CSIRO-developed ‘Going for Gold’ process replaces cyanide with a reagent, known as thiosulphate, creating a relatively cost-effective, non-toxic and safe alternative to conventional cyanide-based gold recovery process.Clean Mining will deliver the new technology solution to a global market of gold producers, offering technology products and licences as well as turn-key processing plant options, plus equipment and product support throughout the mine life.Clean Mining Managing Director, Jeff McCulloch, says the technology is suitable for new greenfields mines, locations where cyanide cannot be used or is banned, as well as in existing mines looking to upgrade and transition to the new technology. “This technology provides gold miners with an opportunity to proactively evolve their environmental, social and governance (ESG) standards,” Mr McCullloch said. “This new technology literally delivers a new gold standard for the global gold industry. “The technology is scalable and cost effective, and the process has been tested and proven at an industrial-scale to deliver commercially viable results.” Clean Mining are currently in negotiations with ICA Mining Services Pty Ltd in the Northern Territory of Australia to commission the first commercial plant to process gold using this technology, and with Nu-Fortune Gold to commission a plant in the Goldfields of Western Australia.Source: CSIRO .
