08:53
See our entire index of CompTIA Security+ videos at http://www.FreeSecurityPlus.com - Trojans are the sneakiest of computer attacks, and they often leave backdoors open for other malware to use. In this video, you'll learn about Trojans and backdoors, and we'll infect one of our own computers to show you how they work.

What is Cryptocurrency. Guide for Beginners  A cryptocurrency is a digital or virtual currency designed to work as a medium of exchange. It uses cryptography to secure and verify transactions as well as to control the creation of new units of a particular cryptocurrency. Essentially, cryptocurrencies are limited entries in a database that no one can change unless specific conditions are fulfilled.  History There have been many attempts at creating a digital currency during the 90s tech boom, with systems like Flooz, Beenz and DigiCash emerging on the market but inevitably failing. There were many different reasons for their failures, such as fraud, financial problems and even frictions between companies’ employees and their bosses. Notably, all of those systems utilized a Trusted Third Party approach, meaning that the companies behind them verified and facilitated the transactions. Due to the failures of these companies, the creation of a digital cash system was seen as a lost cause for a long while. Then, in early 2009, an anonymous programmer or a group of programmers under an alias Satoshi Nakamoto introduced Bitcoin. Satoshi described it as a ‘peer-to-peer electronic cash system.’ It is completely decentralized, meaning there are no servers involved and no central controlling authority. The concept closely resembles peer-to-peer networks for file sharing.  One of the most important problems that any payment network has to solve is double-spending. It is a fraudulent technique of spending the same amount twice. The traditional solution was a trusted third party - a central server - that kept records of the balances and transactions. However, this method always entailed an authority basically in control of your funds and with all your personal details on hand. In a decentralized network like Bitcoin, every single participant needs to do this job. This is done via the Blockchain - a public ledger of all transaction that ever happened within the network, available to everyone. Therefore, everyone in the network can see every account’s balance. Every transaction is a file that consists of the sender’s and recipient’s public keys (wallet addresses) and the amount of coins transferred. The transaction also needs to be signed off by the sender with their private key. All of this is just basic cryptography. Eventually, the transaction is broadcasted in the network, but it needs to be confirmed first. Within a cryptocurrency network, only miners can confirm transactions by solving a cryptographic puzzle. They take transactions, mark them as legitimate and spread them across the network. Afterwards, every node of the network adds it to its database. Once the transaction is confirmed it becomes unforgeable and irreversible and a miner receives a reward, plus the transaction fees. Essentially, any cryptocurrency network is based on the absolute consensus of all the participants regarding the legitimacy of balances and transactions. If nodes of the network disagree on a single balance, the system would basically break. However, there are a lot of rules pre-built and programmed into the network that prevents this from happening. Cryptocurrencies are so called because the consensus-keeping process is ensured with strong cryptography. This, along with aforementioned factors, makes third parties and blind trust as a concept completely redundant. What can you do with cryptocurrency Buy goods  In the past, trying to find a merchant that accepts cryptocurrency was extremely difficult, if not impossible. These days, however, the situation is completely different. There are a lot of merchants - both online and offline - that accept Bitcoin as the form of payment. They range from massive online retailers like Overstock and Newegg to small local shops, bars and restaurants. Bitcoins can be used to pay for hotels, flights, jewelery, apps, computer parts and even a college degree. Other digital currencies like Litecoin, Ripple, Ethereum and so on aren’t accepted as widely just yet. Things are changing for the better though, with Apple having authorized at least 10 different cryptocurrencies as a viable form of payment on App Store. Of course, users of cryptocurrencies other than Bitcoin can always exchange their coins for BTCs. Moreover, there are Gift Card selling websites like Gift Off, which accepts around 20 different cryptocurrencies. Through gift cards, you can essentially buy anything with a cryptocurrency. Finally, there are marketplaces like Bitify and OpenBazaar that only accept cryptocurrencies. Read more in the article “What can I buy with Bitcoins?” Invest  Many people believe that cryptocurrencies are the hottest investment opportunity currently available. Indeed, there are many stories of people becoming millionaires through their Bitcoin investments. Bitcoin is the most recognizable digital currency to date, and just last year one BTC was valued at $800. In November 2017, the price

WILL BITCOIN FACE A SIMILAR BULL RUN AS IN 2017 ?
 
03:43
What is Cryptocurrency. Guide for Beginners A cryptocurrency is a digital or virtual currency designed to work as a medium of exchange. It uses cryptography to secure and verify transactions as well as to control the creation of new units of a particular cryptocurrency. Essentially, cryptocurrencies are limited entries in a database that no one can change unless specific conditions are fulfilled.  History There have been many attempts at creating a digital currency during the 90s tech boom, with systems like Flooz, Beenz and DigiCash emerging on the market but inevitably failing. There were many different reasons for their failures, such as fraud, financial problems and even frictions between companies’ employees and their bosses. Notably, all of those systems utilized a Trusted Third Party approach, meaning that the companies behind them verified and facilitated the transactions. Due to the failures of these companies, the creation of a digital cash system was seen as a lost cause for a long while. Then, in early 2009, an anonymous programmer or a group of programmers under an alias Satoshi Nakamoto introduced Bitcoin. Satoshi described it as a ‘peer-to-peer electronic cash system.’ It is completely decentralized, meaning there are no servers involved and no central controlling authority. The concept closely resembles peer-to-peer networks for file sharing.  One of the most important problems that any payment network has to solve is double-spending. It is a fraudulent technique of spending the same amount twice. The traditional solution was a trusted third party - a central server - that kept records of the balances and transactions. However, this method always entailed an authority basically in control of your funds and with all your personal details on hand. In a decentralized network like Bitcoin, every single participant needs to do this job. This is done via the Blockchain - a public ledger of all transaction that ever happened within the network, available to everyone. Therefore, everyone in the network can see every account’s balance. Every transaction is a file that consists of the sender’s and recipient’s public keys (wallet addresses) and the amount of coins transferred. The transaction also needs to be signed off by the sender with their private key. All of this is just basic cryptography. Eventually, the transaction is broadcasted in the network, but it needs to be confirmed first. Within a cryptocurrency network, only miners can confirm transactions by solving a cryptographic puzzle. They take transactions, mark them as legitimate and spread them across the network. Afterwards, every node of the network adds it to its database. Once the transaction is confirmed it becomes unforgeable and irreversible and a miner receives a reward, plus the transaction fees. Essentially, any cryptocurrency network is based on the absolute consensus of all the participants regarding the legitimacy of balances and transactions. If nodes of the network disagree on a single balance, the system would basically break. However, there are a lot of rules pre-built and programmed into the network that prevents this from happening. Cryptocurrencies are so called because the consensus-keeping process is ensured with strong cryptography. This, along with aforementioned factors, makes third parties and blind trust as a concept completely redundant. What can you do with cryptocurrency Buy goods  In the past, trying to find a merchant that accepts cryptocurrency was extremely difficult, if not impossible. These days, however, the situation is completely different. There are a lot of merchants - both online and offline - that accept Bitcoin as the form of payment. They range from massive online retailers like Overstock and Newegg to small local shops, bars and restaurants. Bitcoins can be used to pay for hotels, flights, jewelery, apps, computer parts and even a college degree. Other digital currencies like Litecoin, Ripple, Ethereum and so on aren’t accepted as widely just yet. Things are changing for the better though, with Apple having authorized at least 10 different cryptocurrencies as a viable form of payment on App Store. Of course, users of cryptocurrencies other than Bitcoin can always exchange their coins for BTCs. Moreover, there are Gift Card selling websites like Gift Off, which accepts around 20 different cryptocurrencies. Through gift cards, you can essentially buy anything with a cryptocurrency.

PFSense Tutorial Series Firewal PFSense 2.3.3 l Installation & Configuration P2 Tutorial in Urdu
 
11:29
This video tutorial shows pfSense 2.4 Firewall Installation and Overview on Oracle VirtualBox step by step. This tutorial is also helpful to installing pfSense 2.4 on physical computer hardware or bare-metal server. Steps: 1- Create Virtual Machine on Oracle VirtualBox 2- Start pfSense 2.4 Firewall Installation 3- pfSense 2.4 Initial Configuration via Web GUI 4- pfSense 2.4 Overview pfSense 2.4 New Features and Improvements pfSense is a free, open source customised distribution of FreeBSD specifically tailored for use as a firewall and router that is entirely managed via web interface. pfSense 2.4.0 includes a long list of significant changes in pfSense software and in the underlying operating system and dependencies. Changes for pfSense 2.4.0 include: - FreeBSD 11.1-RELEASE as the base Operating System - New pfSense installer based on bsdinstall, with support for ZFS, UEFI, and multiple types of partition layouts (e.g. GPT, BIOS) - Support for Netgate ARM devices such as the SG-1000 - OpenVPN 2.4.x support, which brings features like AES-GCM ciphers, speed improvements, Negotiable Crypto Parameters (NCP), TLS encryption, and dual stack/multihome - WebGUI improvements, such as a new login page, improved GET/POST CSRF handling, significant improvements to the Dashboard and its AJAX handling - Certificate Management improvements including CSR signing and international character support - Captive Portal has been rewritten to work without multiple instances of ipfw pfSense Website: https://www.pfsense.org/ Download pfSense 2.4 ISO: https://www.pfsense.org/download/ pfSense 2.4 Minimum System Requirements pfSense 2.4 has low minimum system requirements (for example 256 MB RAM and 500 MHz CPU) and can be installed on hardware with x86-64 architecture It is also available for embedded system hardware using Compact Flash or SD cards. pfSense also supports virtualized installation. Download Link http://adf.ly/1gu8WX Appliance Guidance The following outlines the best practices for choosing the appliance best suitable for your environment. Feature Considerations Most features do not factor into hardware sizing, although a few will have a significant impact on hardware utilization: VPN - Heavy use of any of the VPN services included in the pfSense software will increase CPU requirements. Encrypting and decrypting traffic is CPU intensive. The number of connections is much less of a concern than the throughput required. AES-NI acceleration of IPsec significantly reduces CPU requirements on platforms that support it. Captive Portal - While the primary concern is typically throughput, environments with hundreds of simultaneous captive portal users (of which there are many) will require slightly more CPU power than recommended above. Large State Tables - State table entries require about 1 KB of RAM each. The default state table size is calculated based on 10% of the available RAM in the firewall. For example, a firewall with 1 GB of RAM will default to 100,000 states which when full would use about 100 MB of RAM. For large environments requiring state tables with several hundred thousand connections, or millions of connections, ensure adequate RAM is available. Packages - Some of the packages increase RAM requirements significantly. Snort and ntop are two that should not be installed on a system with less than 1GB RAM. __/LINKS\_ ================================================ Channel: http://adf.ly/1gI9Ms Face Book: http://adf.ly/1gY3S1 Twitter: http://adf.ly/1gY3R5 InstaGram: http://adf.ly/1gY3PN Stumbler: http://adf.ly/1gY3VD Website: http://adf.ly/1gQn0O ================================================ Please like and share the video ⍨ Thanks For Watching ⍨ ☛ Your Questions and Comments are Welcome. ☛ Don't forget to Leave a Thumbs Up. ☛ SUBSCRIBE Our Channel to Receive New Awesome Videos.

If you like this video and want to support me, go this page for my donation Paypal or crypto addresses: https://www.youtube.com/c/mobilefish/about This is part 14 of the LoRa/LoRaWAN tutorial. In this video series different topics will be explained which will help you to understand LoRa/LoRaWAN. It is recommended to watch each video sequentially as I may refer to certain LoRa/LoRaWAN topics explained earlier. In this video I will explain what Forward Error Correction and coding rates are. Forward Error Correction (FEC) is the process where error correction bits are added to the transmitted data. These redundant bits helps to restore the data when the data gets corrupted by interference. If more error correction bits are added, the easier the data can be corrected. However by adding more error correction bits, more data is transmitted which decreases the battery life. The coding rate refers to the proportion of the transmitted bits that actually carries information. LoRa allowed coding rate values: CR = 4/5, 4/6, 4/7 or 4/8. Another notation: CR = 4 / (4 + CR) where CR = 1,2,3,4 If CR=1, CR = 4/5 If CR=2, CR = 4/6 If CR=3, CR = 4/7 If CR=4, CR = 4/8 Check out all my other LoRa/LoRaWAN tutorial videos: https://www.youtube.com/playlist?list=PLmL13yqb6OxdeOi97EvI8QeO8o-PqeQ0g Subscribe to my YouTube channel: https://www.youtube.com/channel/UCG5_CT_KjexxjbgNE4lVGkg?sub_confirmation=1 The presentation used in this video tutorial can be found at: https://www.mobilefish.com/developer/lorawan/lorawan_quickguide_tutorial.html #mobilefish #lora #lorawan

What is Cryptocurrency. Guide for Beginners A cryptocurrency is a digital or virtual currency designed to work as a medium of exchange. It uses cryptography to secure and verify transactions as well as to control the creation of new units of a particular cryptocurrency. Essentially, cryptocurrencies are limited entries in a database that no one can change unless specific conditions are fulfilled.  History There have been many attempts at creating a digital currency during the 90s tech boom, with systems like Flooz, Beenz and DigiCash emerging on the market but inevitably failing. There were many different reasons for their failures, such as fraud, financial problems and even frictions between companies’ employees and their bosses. Notably, all of those systems utilized a Trusted Third Party approach, meaning that the companies behind them verified and facilitated the transactions. Due to the failures of these companies, the creation of a digital cash system was seen as a lost cause for a long while. Then, in early 2009, an anonymous programmer or a group of programmers under an alias Satoshi Nakamoto introduced Bitcoin. Satoshi described it as a ‘peer-to-peer electronic cash system.’ It is completely decentralized, meaning there are no servers involved and no central controlling authority. The concept closely resembles peer-to-peer networks for file sharing.  One of the most important problems that any payment network has to solve is double-spending. It is a fraudulent technique of spending the same amount twice. The traditional solution was a trusted third party - a central server - that kept records of the balances and transactions. However, this method always entailed an authority basically in control of your funds and with all your personal details on hand. In a decentralized network like Bitcoin, every single participant needs to do this job. This is done via the Blockchain - a public ledger of all transaction that ever happened within the network, available to everyone. Therefore, everyone in the network can see every account’s balance. Every transaction is a file that consists of the sender’s and recipient’s public keys (wallet addresses) and the amount of coins transferred. The transaction also needs to be signed off by the sender with their private key. All of this is just basic cryptography. Eventually, the transaction is broadcasted in the network, but it needs to be confirmed first. Within a cryptocurrency network, only miners can confirm transactions by solving a cryptographic puzzle. They take transactions, mark them as legitimate and spread them across the network. Afterwards, every node of the network adds it to its database. Once the transaction is confirmed it becomes unforgeable and irreversible and a miner receives a reward, plus the transaction fees. Essentially, any cryptocurrency network is based on the absolute consensus of all the participants regarding the legitimacy of balances and transactions. If nodes of the network disagree on a single balance, the system would basically break. However, there are a lot of rules pre-built and programmed into the network that prevents this from happening. Cryptocurrencies are so called because the consensus-keeping process is ensured with strong cryptography. This, along with aforementioned factors, makes third parties and blind trust as a concept completely redundant. What can you do with cryptocurrency Buy goods  In the past, trying to find a merchant that accepts cryptocurrency was extremely difficult, if not impossible. These days, however, the situation is completely different. There are a lot of merchants - both online and offline - that accept Bitcoin as the form of payment. They range from massive online retailers like Overstock and Newegg to small local shops, bars and restaurants. Bitcoins can be used to pay for hotels, flights, jewelery, apps, computer parts and even a college degree. Other digital currencies like Litecoin, Ripple, Ethereum and so on aren’t accepted as widely just yet. Things are changing for the better though, with Apple having authorized at least 10 different cryptocurrencies as a viable form of payment on App Store. Of course, users of cryptocurrencies other than Bitcoin can always exchange their coins for BTCs. Moreover, there are Gift Card selling websites like Gift Off, which accepts around 20 different cryptocurrencies. Through gift cards, you can essentially buy anything with a cryptocurrency. Finally, there are marketplaces like Bitify and OpenBazaar that only accept cryptocurrencies.

ICO Review: Tolar (TOL) - Scalable Blockchain Leveraging DLT

Tolar is a blockchain solution based on its HashNET protocol that aims to resolve the issues facing current blockchain technology.

We do not offer promotional or advertising services. Our content is based on our own research, analysis and personal opinion. _______________________________________ What does the company/project do? Tolar is a work-in-progress blockchain solution based on its own HashNET protocol that aims to resolve the issues facing current blockchain technology including cost, slow transaction speed, and scalability. HashNET consensus uses “redundancy reduced gossip” and “virtual voting” protocol, which aims to provide a fair and fast byzantine fault tolerant consensus algorithm. As no mining is required, less computing resources and therefore, electrical power, is used. Using Proof-of-Stake (PoS) and masternodes to reach distributed consensus, the platform aims to achieve 200,000 transactions per second (TPS), making it faster than many of the incumbent blockchains. Features of HashNET include transparency of funds, speed, mobile compatible, ability to grow, and decentralization. A prototype released by the team in June 2018 has demonstrated 130,000 TPS during the live demo and, according to the team, reached up to 150,000 TPS during their own test runs. _______________________________________ What are the tokens used for and how can token holders make money? The TOL token is the network’s native token and is used to incentivize various users of the platform: - Masternode owners: Help secure the HashNET network. Masternode owners are required to meet minimum server requirements and must stake 500,000 TOL tokens as collateral to prevent malicious activity. They are rewarded with transaction fees from all transactions that they validate correctly and with incentives from Tolar’s monetary fund in the form of TOL tokens. - Regular nodes: Regular nodes are tasked with propagating events and verifying correctness and are rewarded with tokens. They are able to do staking as well but have a lower reward percentage compared to masternodes. TOL tokens should appreciate in value as more participants join and use the network which is in turn driven by factors such as attractiveness of node rewards, processing speed, security, network transaction fees, etc. _______________________________________ Opportunities - The project already has a prototype with a demonstrated speed of 130,000 TPS during a live demo and reaching up to 150,000 during private test runs. This is already quite close to the project’s goal of achieving 200,000 TPS. However, it was with only 11 masternodes. The performance is expected to decline when more nodes join the network. - Supported by their strategic partner, COTRUGLI Business School, a business school in SE Europe with more than 2,000 MBA alumni and over 20,000 clients. However, it is unclear how the business school is going to support the project. _______________________________________ Concerns - The team doesn’t appear to be particularly strong technically as compared with other similar blockchain projects that we have come across. The CTO is said to have 2 years of blockchain experience but we can only see he has been a blockchain developer for Blocknet for 6 months. There’s no information on Moon Code, the mobile app company he owned/developed and claims to provide some blockchain services. - The team’s business development strategy is to collaborate with the largest ICT companies in the fields of IoT, logistics, healthcare and government. However, they have not built any partnerships yet and it is uncertain if they can do this. - There are many blockchain projects looking to solve the issues of blockchain scalability and transaction speed. HashNET doesn’t seem to have any significant differentiating features. _______________________________________ Disclaimer The information in this video is for educational purposes only and is not investment advice.

ANDREW YANG NYC RALLY “CHALLENGE F***ING ACCEPTED” | RACE FOR 2020 | BASED MEDIA BROOKLYN
 
07:32
“challenge f***ing accepted” Andrew Yang exclaimed during his NYC rally regarding running for president and referenced himself as “the Asian man standing next to Joe Biden” in the Democratic debate he has now qualified for. Andrew Yang is the unconventional Democratic presidential candidate with little to non political background or experience, however, he is spinning this to his advantage - being a tech entreprenuer from an immigrant family, who understands humanity and the technology boom that is forecasted to displace thousands of Americans from their current working positions and careers. Andrew Yang and the coined “Yang Gang” held their New York City rally on the evening of Tuesday, May 14, 2019. The NYC rally was anticipated to be the largest rally yet in Yang’s campaign with over 5,000 RSVP’s. Stormy rainy weather impacted the attendance turnout to the public rally, held near NYU at Washington Square Park, with an approximate 2,500 person turnout according to the Yang campaign. Although New York City was anticipated to be the largest rally to date, the attendance did not surpass that of a rally in Seattle, home of Amazon, which had more than 4,000 supporters. The passionate supporters who turned out with umbrellas in hand were boasting rally signs stating, “Yang Gang” “Humanity First,” “MATH” and “POWER POINT”. You’d have to already be in the know to understand the last two coined campaign terms MATH and POWERPOINT, and Andrew Yang is running his campaign on bringing facts, data, numbers and math to the conversation to back up his Presidential policy plans on putting people first. ANDREW YANG’S 3 POLICY PILLARS: 1. UNIVERSAL INCOME Andrew would implement a Universal Basic Income, ‘the Freedom Dividend,’ of $1,000/month for every American adult over the age of 18. This is independent of one’s work status or any other factor. PROBLEMS TO BE SOLVED: Approx. 40 million Americans live below the poverty line. Technology is quickly displacing a large number of workers, and the pace will only increase as automation and other forms of artificial intelligence become more advanced. ⅓ of American workers will lose their jobs to automation by 2030 according to McKinsey. This has the potential to destabilize our economy and society if unaddressed. Good jobs are becoming more and more scarce and Americans are already working harder and harder for less and less. It is necessary to support and preserve a robust consumer economy. Many Americans are stuck in the wrong jobs because of a need to survive. There are many positive social activities that are currently impossible for many to do because they lack the financial resources to dedicate time to it, including taking care of a child or sick loved one, and volunteering in the community. 2. MEDICARE FOR ALL America is one of the few industrialized nations not to provide healthcare for all of its citizens. PROBLEMS TO BE SOLVED Millions of Americans live without healthcare. Even those with healthcare are often bankrupted by healthcare costs. Many Americans who have healthcare have policies that don’t afford them the opportunity to receive proper care. Healthcare costs in this country are relatively high, and outcomes are relatively poor. Doctors are incentivized to act as factory workers, churning through patients and prescribing redundant tests, rather than doing what they’d prefer—spending extra time with each patient to ensure overall health. Many health issues fall through the cracks because doctors rely on patients to bring up issues rather than treating each one holistically. Employees are tied to their employers because they receive the healthcare benefits through them. 3. HUMAN-CENTERED CAPITALISM The focus of our economy should be to maximize human welfare. PROBLEMS TO BE SOLVED At present, the Market systematically tends to undervalue many things, activities, and people, many of which are core to the human experience.

SUBSCRIBE TO US FOR MORE INFORMATIVE IT KNOWLEDGE! SSL certificates keep online interactions private even though they travel across the public Internet. They also help customers gain the confidence to transact with your website. The right SSL certificate depends on the level of assurance your customers need and the minimum level of encryption your organization requires. An SSL certificate is a bit of code on your web server that provides security for online communications. When a web browser contacts your secured web site, the SSL certificate enables an encrypted connection. It’s kind of like sealing a letter in an envelope before sending it through the mail.

Protection Against Cyber Attacks: Introducing Resilience for SCADA Networks Presented by Antonios Gouglidis, Lancaster University Abstract: The sovereignty of nations is highly dependent on the continuous and uninterrupted operation of critical infrastructures. Recent security incidents on SCADA networks show that threats in these environments are increasing in sophistication and number. To protect critical infrastructures against cyber attacks and to cope with their complexity, we advocate the application of a resilience strategy. This strategy provides the guidelines and processes to investigate and ensure the resilience of systems. In this abstract, we briefly refer to our definition of resilience, our research work on the verification of resilience policies, and our resilience architecture for protecting SCADA networks against cyber attacks. This presentation was given at the Symposium on Innovative Smart Grid Cybersecurity Solutions in March 2017. The agenda and other details can be found online: http://smartgrid-cybersecurity.events/

Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

PCIe has numerous improvements over the older standards, including higher maximum system bus throughput, lower I/O pin count and smaller physical footprint, better performance scaling for bus devices, a more detailed error detection and reporting mechanism (Advanced Error Reporting, AER), and native hot-swap functionality. More recent revisions of the PCIe standard provide hardware support for I/O virtualization. Defined by its number of lanes, the PCI Express electrical interface is also used in a variety of other standards, most notably the laptop expansion card interface ExpressCard and computer storage interfaces SATA Express and M.2. Format specifications are maintained and developed by the PCI-SIG (PCI Special Interest Group), a group of more than 900 companies that also maintain the conventional PCI specifications.
