LoRa/LoRaWAN tutorial 14: Forward Error Correction and Coding Rate
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

Information Theory part 9: What is a bit?
How can we quantify/measure an information source? We introduce the ideas of Nyquist & Hartley using a simple game involving yes/no questions. It's important to realize all of this happened before Claude Shannon arrived on the scene. However, this measure applies only when communication involves random sequences...

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.

Great Financial Crisis Ten Years On: Past Role and Current Risks from China | Anne-Stevenson Yang
Subscribe to Hidden Forces and gain access to the episode overtime, transcript, and show rundown here: http://hiddenforces.io/subscribe In Episode 85 of Hidden Forces, Demetri Kofinas speaks with China expert Anne Stevenson-Yang about the imminent dangers facing global financial markets in the event of a break in the renminbi-dollar peg. In the years leading up to the Great Financial Crisis, it was generally understood that the Chinese were artificially depressing the value of the RMB vis-à-vis the USD, in order maintain an abnormally large current account surplus that would be recycled into western financial markets in the form of government securities, equities, real estate, etc. By recycling so much of the proceeds from trade back into foreign markets, the CCP managed to maintain a lower exchange rate than it otherwise would be, were it to convert those dollars back into renminbi. In other words, China was suppressing the value of its currency. Bob Wittbrot calls this recycling process the “Boomerang Greenback.” This dynamic worked extraordinary well until the world went into recession around the time of the great financial crisis, which marked a peak in China’s current account. The CCP also met the crisis by expanding bank lending, easing credit, and fueling investment even further. In addition, by maintaining interest rates and the cost of capital well-below the rate of inflation during China’s multi-decade boom, the CCP has managed to keep households’ share of the economy at low enough levels to induce an overall high-savings rate for the country (by having less disposable income than would otherwise be expected for an economy this size, the average Chinese citizen spends less on consumption than he or she otherwise would, absent financial repression). This has been an additional shot in the arm for investment. At some point post-2008 (judging from their foreign exchange reserves, this appears to have started somewhere around the start of 2014) China went from artificially suppressing the value of its currency to artificially supporting it. Unlike a country like Thailand, however, whose currency peg famously broke under the speculative attacks of foreign investors during the 1997-98’ Asian Financial Crisis, the Chinese have managed to avoid such a scenario on account of maintaining a closed capital account (exercising tight capital controls). Coupling that with a current account surplus, the CCP has been able to obtain the hard currency it has needed in the last 5 years or so in order to buy the various inputs required to run their economy and keep the cycle going. The problem is that China generated a tremendous amount of money and credit since the Follow us on Twitter: https://twitter.com/hiddenforcespod Follow us on Facebook: https://www.facebook.com/hiddenforcespod/ Follow us on Instagram: https://www.instagram.com/hiddenforcespod/ Follow us on Twitter: https://twitter.com/hiddenforcespod Follow us on Facebook: https://www.facebook.com/hiddenforcespod/ Follow us on Instagram: https://www.instagram.com/hiddenforcespod/

DEF CON 23 - Mahdi Namazifar - Detecting Randomly Generated Strings
Numerous botnets employ domain generation algorithms (DGA) to dynamically generate a large number of random domain names from which a small subset is selected for their command and control. A vast majority of DGA algorithms create random sequences of characters. In this work we present a novel language-based technique for detecting strings that are generate by chaining random characters. To evaluate randomness of a given string (domain name in this context) we lookup substrings of the string in the dictionary that we’ve built for this technique, and then we calculate a randomness score for the string based on several different factors including length of the string, number of languages that cover the substrings, etc. This score is used for determining whether the given string is a random sequence of characters. In order to evaluate the performance of this technique, on the one hand we use 9 known DGA algorithms to create random domain names as DGA domains, and on the other hand we use domain names from the Alexa 10,000 as likely non-DGA domains. The results show that our technique is more than 99% accurate in detecting random and non-random domain names. Speaker Bio: Mahdi Namazifar is currently a Senior Data Scientist with Talos team of Cisco Systems' San Francisco Innovation Center (SFIC). He graduated his PhD in Operations Research from the University of Wisconsin-Madison in 2011. His PhD work was on theoretical and computational aspects of mathematical optimization.

DEF CON 12 - Dan Kaminsky, Black Ops of TCP/IP 2004
Dan Kaminsky, Black Ops of TCP/IP 2004 Continuing the research done in previous years on advanced protocol manipulation and the high speed evaluation of large network characteristics, this year's Black Ops of TCP/IP goes into new territory with a deep analysis of the Domain Name System. A core element of the TCP/IP application suite, it is everywhere and there is unexpected power contained within. * Interesting Facets of the Global DNS Architecture: A high speed scanner for DNS servers, modeled after my TCP scanner 'scanrand", recently executed several Internet-scale sweeps of the net. Surprising results, with direct implications for computer forensics operations, will be discussed and analyzed. * Distributed, High Speed, Large File Dissemination via DNS, A.K.A. "Reinventing the Square Wheel." Although there have been previous attempts to serve files over the DNS architecture, none have been even remotely usable. I will discuss a new approach that, through its significant performance improvement, is indeed remotely usable. * One-To-Many Streaming Data Dissemination over DNS: The previous system maximizes speed at the expense of making streaming impossible. We will discuss an interesting alternate approach that almost usefully distributes streaming audio data to endpoints via their DNS queries. * SSH over DNS: I will demonstrate a cross-platform, userspace mechanism for moving SSH data over DNS queries. This has implications for captive wireless portals, which often allow bidirectional DNS traffic. * To complete this work, some enormously complex data needed to be understood, and tools were worked with and written towards that end. Experimental 3D information visualization mechanisms and tools are thus available to be demonstrated, extending from using a 3D renderer usually used for MRI medical data as a generic static 3D canvas to using a custom OpenGL particle plotter to dynamically plot multidimensional factors of incoming data streams. A number of other topics will be raised as well, including: * Uses and abuses of remotely visible incrementers and decrementers (such as the IPID field in many TCP/IP stacks, and initial TTL values on arbitrary DNS queries) * Uses of generic packet race conditions, whereby useful information can be gleaned from which packet of a relatively large set effects the state change * Protocol transliteration between TCP and UDP, allowing unreliable communication over what appears to be a TCP session, and allowing reliable data to be transmitted, with zero data expansion, over a UDP link * Potential solutions to the SSH bastion host security problem, whereby the invocation of remote ssh binaries at a firewall or "bastion host" opens up a single point of major failure for a server infrastructure. Dan Kaminsky, also known as Effugas, is a Senior Security Consultant for Avaya's Enterprise Security Practice, where he works on large-scale security infrastructure. Dan's experience includes two years at Cisco Systems designing security infrastructure for large-scale network monitoring systems, and he is best known for his work on the ultra-fast port scanner scanrand, part of the "Paketto Keiretsu", a collection of tools that use new and unusual strategies for manipulating TCP/IP networks. He authored the Spoofing and Tunneling chapters for "Hack Proofing Your Network: Second Edition", and has delivered presentations at several major industry conferences, including Linuxworld, DefCon, and past Black Hat Briefings. Dan was responsible for the Dynamic Forwarding patch to OpenSSH, integrating the majority of VPN-style functionality into the widely deployed cryptographic toolkit. Finally, he founded the cross-disciplinary DoxPara Research in 1997, seeking to integrate psychological and technological theory to create more effective systems for non-ideal but very real environments in the field. Dan is based in Silicon Valley.

EC2 Free Tier Bitnami Applications in AWS Marketplace  - WordPress Apache MySQL PHP-FPM Google GCP
https://marvel-it.icu/vps-domain-hosting/ec2-free-tier-bitnami-applications-in-aws-marketplace-wordpress-apache-mysql-php-fpm-google-gcp Developers are in a whole new world of 4.0 era, computing resources come with greater power, flexibility as well as complexity. We have giant firms like Google, Amazon with GCP, AWS, etc. The old days with a single VPS with all in one Ubuntu-Debian, NGINX-Apache, MySQL-MariaDB, PHP-FPM is gone, now, each component tends to have a dedicated "container". That's why we need a management platform to manage a WordPress blog! For simplicity, we can use Bitnami as a managed WordPress hosting service that hides the hassle tasks about: install PHP, deploy database, secure the server, etc. behind. All you get is an integrated dashboard with wrappers in the form of buttons/menus to control the above stuff. Let's image how simple it is to click on a WordPress icon and then a fully working web server is being deployed under the hood? [00:47] "If you’re new to the cloud, the easiest way to get started with Amazon Web Services is with Bitnami. Bitnami provides pre-packaged application images for AWS Cloud servers, so that you can get productive with your new server immediately" - bitnami.com http://bit.ly/bitnami-market [00:56] Bitnami offers WordPress deployment solutions range from newbies to experienced developers. - Bitnami Launchpad for AWS Cloud - AWS Marketplace - AWS Console - Amazon Lightsail Remember that Bitnami is a 3rd service/intermediate layer between you and computing providers. That's why you have to register to Free program, AWS Free Tier in this case. Make sure you are kept up to date information about these trial programs to avoid extra credit card charges. For instance, AWS only free for selected forms of services: t2.micro VPS Meanwhile, Google GCP gives you 300$ to use whatever services as long as you are not run out of the budget. [01:19] Always free These free tier offers do not expire and are available to all AWS customers 12 months free Enjoy these offers for 12-months following your initial sign-up date to AWS Trials Short-term free trial offers are available through many different software solutions http://aws.amazon.com/free Every fee is transparent as long as you choose the right eligible services in the Free Tier. I see Google Cloud Platform has a "double free" policy after 300$ free trial credit is gone, you still have the Free Tier program to apply for, and I feel no struggle to run my blog on that limited resources. [02:17] GCP Free Tier 12 months and $300 free credit to get you started. Always Free* products to keep you going. http://cloud.google.com/free [03:07] [ Get Started with Bitnami Applications in the AWS Marketplace ] To get activated on Amazon Free Tier you can register an AWS account with a working phone number and a credit card with at least 1$ in the balance. They will text or call you with a secret code, then withdraw about 1$ to verify the Visa/Master card. AWS may use the billing address associated with your default payment method as one of the many factors to determine what taxes apply. You can update your default payment preference and billing address by editing your default payment method below. [04:53] "When a new payment card is added to an AWS account, a small charge is sent to verify that the card is valid, and that the card hasn’t been reported lost or stolen. For AWS customers, the temporary authorization charge is 1.00 USD. AWS doesn’t proceed with the charge, and the charge should disappear within three to five business days" - amazon.com http://bit.ly/aws-author-charge Nowadays, encrypted communication with Public-key cryptography is mandatory across mediums, that why you have to generate a Key Pair/SSH key so that secure accessing through SSH, SFTP, etc are available with the Ubuntu VPS. Keep in mind that cloud service providers work with region different, based on the location that you would like to deploy the VPS/cloud instance, change the active region accordingly at first. Be aware that Free Tier may not be applied outside the US, so EU, Asia, etc. will get charged with standard fees. Save the private SSH key to a synchronized folder to backup it. Losing the key result an AWS server rebuilding as you can not access the machine anymore. That is not kind of a password that you can recover later by receiving OTP message or answering security questions. Then with encrypted disks, all unbacked-up data will remain inaccessible. WordPress itself is a managed CMS platform, so everything Bitnami Launchpad offers like: backup, upgrade, analytics, etc. are redundancy. We should go with AWS Marketplace to get the best compatibility with Amazon deployment via the Bitnami AMI...

What is RADIO-FREQUENCY IDENTIFICATION? What does RADIO-FREQUENCY IDENTIFICATION mean? RADIO-FREQUENCY IDENTIFICATION meaning - RADIO-FREQUENCY IDENTIFICATION definition - RADIO-FREQUENCY IDENTIFICATION explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically stored information. Passive tags collect energy from a nearby RFID reader's interrogating radio waves. Active tags have a local power source such as a battery and may operate at hundreds of meters from the RFID reader. Unlike a barcode, the tag need not be within the line of sight of the reader, so it may be embedded in the tracked object. RFID is one method for Automatic Identification and Data Capture (AIDC). RFID tags are used in many industries, for example, an RFID tag attached to an automobile during production can be used to track its progress through the assembly line; RFID-tagged pharmaceuticals can be tracked through warehouses; and implanting RFID microchips in livestock and pets allows positive identification of animals. Since RFID tags can be attached to cash, clothing, and possessions, or implanted in animals and people, the possibility of reading personally-linked information without consent has raised serious privacy concerns. These concerns resulted in standard specifications development addressing privacy and security issues. ISO/IEC 18000 and ISO/IEC 29167 use on-chip cryptography methods for untraceability, tag and reader authentication, and over-the-air privacy. ISO/IEC 20248 specifies a digital signature data structure for RFID and barcodes providing data, source and read method authenticity. This work is done within ISO/IEC JTC 1/SC 31 Automatic identification and data capture techniques. In 2014, the world RFID market is worth US$8.89 billion, up from US$7.77 billion in 2013 and US$6.96 billion in 2012. This includes tags, readers, and software/services for RFID cards, labels, fobs, and all other form factors. The market value is expected to rise to US$18.68 billion by 2026.

What is CONSENSUS-BASED ASSESSMENT? What does CONSENSUS-BASED ASSESSMENT mean? CONSENSUS-BASED ASSESSMENT meaning - CONSENSUS-BASED ASSESSMENT definition - CONSENSUS-BASED ASSESSMENT explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Consensus-based assessment expands on the common practice of consensus decision-making and the theoretical observation that expertise can be closely approximated by large numbers of novices or journeymen. It creates a method for determining measurement standards for very ambiguous domains of knowledge, such as emotional intelligence, politics, religion, values and culture in general. From this perspective, the shared knowledge that forms cultural consensus can be assessed in much the same way as expertise or general intelligence. Consensus-based assessment is based on a simple finding: that samples of individuals with differing competence (e.g., experts and apprentices) rate relevant scenarios, using Likert scales, with similar mean ratings. Thus, from the perspective of a CBA framework, cultural standards for scoring keys can be derived from the population that is being assessed. Peter Legree and Joseph Psotka, working together over the past decades, proposed that psychometric g could be measured unobtrusively through survey-like scales requiring judgments. This could either use the deviation score for each person from the group or expert mean; or a Pearson correlation between their judgments and the group mean. The two techniques are perfectly correlated. Legree and Psotka subsequently created scales that requested individuals to estimate word frequency; judge binary probabilities of good continuation; identify knowledge implications; and approximate employment distributions. The items were carefully identified to avoid objective referents, and therefore the scales required respondents to provide judgments that were scored against broadly developed, consensual standards. Performance on this judgment battery correlated approximately 0.80 with conventional measures of psychometric g. The response keys were consensually derived. Unlike mathematics or physics questions, the selection of items, scenarios, and options to assess psychometric g were guided roughly by a theory that emphasized complex judgment, but the explicit keys were unknown until the assessments had been made: they were determined by the average of everyone's responses, using deviation scores, correlations, or factor scores. One way to understand the connection between expertise and consensus is to consider that for many performance domains, expertise largely reflects knowledge derived from experience. Since novices tend to have fewer experiences, their opinions err in various inconsistent directions. However, as experience is acquired, the opinions of journeymen through to experts become more consistent. According to this view, errors are random. Ratings data collected from large samples of respondents of varying expertise can thus be used to approximate the average ratings a substantial number of experts would provide were many experts available. Because the standard deviation of a mean will approach zero as the number of observations becomes very large, estimates based on groups of varying competence will provide converging estimates of the best performance standards. The means of these groups’ responses can be used to create effective scoring rubrics, or measurement standards to evaluate performance.

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.
