It’s time for decentralized social apps to take over It’s a rare occurrence when people across all generations and sides of the political spectrum agree. One of these things is on the invasiveness and control of big tech. Regardless of your opinion on content moderation or censorship, we can all agree that the power social corporations like Facebook, Twitter and Youtube have over our personal data and online identities is alarming. Every time we provide our information or publish content onto these centralized platforms, that unique piece of data no longer belongs to us. We are given a false sense of ownership over our tweets, videos or blogs, when in reality, the moment we click publish, we give up control and send it to a centralized server owned by one large entity. The challenge is that the growing skepticism of centralized tech giants is also growing in congruence with our reliance on their platforms. The market is ripe for an alternative option from the main social platforms, one that doesn't place corporate monetization first, but the user at the center of it. Why we need a new social platform There are two main issues with traditional social media platforms: censorship and unfair monetization. Despite the constitutional right to free speech, censorship occurs on social platforms because it is technically a private forum owned by an entity. This means that the corporate owner has the right to moderate the feed, remove content that doesn’t fit under their rules, and in the worst-case scenario, block user access to their accounts. When combined with black box algorithms determining what content users see and putting all this power in the hands of even individual people, it’s already been shown to even affect elections around the world so the risks are not restricted on an individual’s level. The other issue is caused by the advertising-driven revenue models of web2 apps, where even one third of the posts can be paid ads. Yet often none of the revenue is shared with the content creators who are then forced to make their own advertorial posts to get compensated or in case of, for example, Reddit moderators are “paid” in Karma points with no monetary value. . So despite how it may appear on social media, the large majority of content creators aren’t actually making a decent living wage on these platforms. How do we solve the problem? To understand the solution, we need to get to the root of the problem and unpack how these centralized networks operate. All social media platforms use some type of social graph - an intricate model that maps out all users and how they relate to one another. Traditional big tech companies own and control the social network and store it in their private data servers. This approach means our online lives are fragmented in separate walled gardens where platforms decide who sees your posts, sometimes arbitrarily delete some of them, or can anytime kick you out and wipe your entire social network for one mishap. With blockchain technology, it is now possible to decentralize the social graph where, instead of corporations, each user owns their profile and all the posts and relationships in it.. Lens Protocol, the brainchild of Aave, is an open-source social graph that empowers any developer to build and launch a blockchain-based social platform. On Lens, your profile, and relationships with any other profiles are represented as NFTs and stored on-chain. These profiles are interoperable across all Lens dApps and stored in your own crypto wallet instead of a centralized platform.. Your profile and content is owned and operated by you and if you’re unhappy with how one app treats you, you can seamlessly move to others without losing your followers. With users in control, this approach requires a genuinely user-focused approach from the apps built for the next generation of social. Phaver, the first mobile app released on Lens, is tackling this with a token economy that is geared to share the success with the content creators, curators and moderators who help to build and maintain the high-quality content feed that any successful social app needs. Creating value for the community is rewarded with tokens while they can be spent to boost content visibility, subscribe to premium content or, for example, a fully ad-free experience, creating a two-sided liquid market that rewards not only the largest influencers, but all parties who help to improve the experience. Furthermore, the governance tokens earned by the best users can also be used to vote on any future decisions, making sure things like content guidelines and algorithms are built for the community instead of the advertisers. Where do we go from here? The social media industry is ready for disruption. Elon Musk recently made the news for his very public remarks on transforming Twitter’s censorship-riddled policies by making a $44 billion acquisition offer. Former POTUS, Donald Trump started his own uncensored social app after falling victim to Twitter’s account banning. All these prominent figures are racing to build a solution that will challenge traditional social platforms. What they fail to realize is that winning doesn’t mean owning and controlling a new platform under their rules. True disruption will happen when power and control are given to the people. Social dApps like Phaver are paving the way for a better digital future that is ethical and empowering for people and we’re ready for it.

千禧一代需要去中心化的社交媒体——这就是为什么

The HackerNoon editorial team has launched this interview series with women in tech to celebrate their achievements and share their struggles. We need more women in technology, and by sharing stories, we can encourage many girls to follow their dreams. Share your story today ! #Tell us about yourself! My name is Regina Sadykova, I am a serial entrepreneur. My key competence is PR and marketing.  As a former journalist, I love to tell stories and explain complicated stuff in a simple way. Currently, I work with  Crypto Funds, NFT, and Web3 companies. #Why did you choose this field in the first place? While I started as a journalist covering tech and Venture Capital back in 2010, my career path led me to a PR role as companies kept requesting me to ‘write another article’ and provide focused coverage. Sometimes people confuse journalists with their publicists, but in my case, the referrals and requests continued over the years from a variety of clients and my PR expertise evolved to support them. In 2016, reflecting what was transpiring in the startup economy globally,  most of my tech clients had migrated to having some involvement in Blockchain or Crypto. I realized that to be the beginning of an entirely new era in tech, so I had to learn a lot of new things: crypto-trading, mining, holding, forks, ICOs, staking, farming etc., but it was exciting and informative. PR in crypto is not just writing or pitching; it requires one to be constantly learning as the industry continues to rapidly evolve. I also love to ‘have skin in the game’, risk my own assets and trade NFTs and participate in ICOs. I have been referred to as a ‘Crypto PR Og’, a badge I wear with pride. #What tech are you most excited/passionate about right now and why? At the moment, I am thrilled about digital fashion. As a fashionista, the idea of having endless clothes without having an endless walk-in closet is exciting. Given the size of the market and having previewed some of the innovations on the way, I believe digital fashion will make a meaningful impact on the industry. DressX, my friend Daria Shapovalova’s startup, is a great example of an innovative startup that will help shape the future of digital fashion. I am also intrigued by digital humans. It started with digital influencers like Lil Miquela (@lilmiquela) and I believe you will see more innovations on the ‘virtual influencer’ front soon. Lastly, I love to work with Layer 1 projects, because leaders in this space are focused on upending the status quo and bringing efficiency and transparency to the rapidly evolving industry. I very much admire the ambitions of Solana, Algorand, and other ecosystem creators. #What are you most worried about right now and why? Mental health! We sometimes underestimate the complexity of our daily digital lives; from consuming and processing a vast volume and variety of data from multiple devices while living thru the literal evolution of systems, it can all be a bit overwhelming sometimes. The advent of deepfakes is also concerning; this dangerous new phenomenon in AI stands to wreak havoc on many segments of our society. #What are your hobbies and interests outside of tech? Fashion, running, and reading. Also, I enjoy building communities. For example, now we are working on a Silicon Society members club. #Let's talk about breaking the glass ceiling. What were the biggest challenges you faced as a woman in tech, and how did you deal with them? Ironically, early in my career, not being taken seriously actually helped me; as a journalist, some people would share sensitive information with me just because I looked like a naive student who asks silly questions, but I was in fact doing my job – getting access to people and information not necessarily available to everyone. With experience comes confidence, and while I certainly have grown personally and professionally to handle some of the situations unique to women making inroads in traditionally male-dominated industries, I have found tech industry leadership to be accommodating and working towards inclusivity. Segments of the industry are new and evolving at such a rapid pace that companies need the best minds and creative ideas from employees, and diversity and inclusivity will be a competitive advantage. #Any questionable misogynistic story/situation you faced/handled, and you want to share with the HackerNoon Fam? I am not quite sure if it can be considered misogyny, but as a person who organizes satellite events for crypto-companies during major conferences, on many occasions, I have observed the practice of inviting young, attractive women just to keep gender balance at the party. These female guests are usually models or select nightclub wait staff who are just tasked with showing up and looking beautiful. On one hand, there is nothing offensive about it but on the other, I wish there were more women in tech who would meaningfully participate in industry events and not be treated like ornaments to enhance the ambiance. #What was the biggest setback/failure that you faced, and how did you manage it? I lost nearly 10 bitcoins. It was painful but I learned a few life lessons - and some technical ones. #What's your biggest achievement that you're really proud of? I am proud to have always gone over and above for my clients and having delivered more than promised. While I have accomplished much, I believe that my greatest achievements are still to come. #In your opinion, why do we see this huge gender gap in the tech industry, and how can we reduce it? There are several reasons for the tech gender gap, some historic and cultural, and others more nuanced and resulting from poor diversity and recruiting policies. I believe we need to encourage more female students to undertake STEM curricula in schools and to evolve our recruiting practices so that our tech talent is reflective of our population. I am encouraged by meaningful strides made by non-profits, local governments, and tech companies to date, but it will take time for them to materialize in a balanced workforce. #Who is your tech idol? Why? I admire Whitney Wolfe Herd, who co-founded Bumble after she was sexually harassed and discriminated against at her former company, Tinder. As VP of Marketing, Whitney was the youngest executive at Tinder. In the face of adversity and challenges, she didn’t give up and instead evolved the business by creating a more woman-friendly app, which turned into a wonderful business. #Do you have any advice for aspiring girls who want to join the field? Learn every day. The new dress is a nice choice, but investing in crypto can be a smart choice. The wise choice is to invest in yourself and your own education all the time.

DYNAMOS AND ELECTRIC MOTORS.

How it Works by Archibald Williams is part of the HackerNoon Books Series. You can jump to any chapter in this book . ELECTRICAL APPARATUS. here Chapter V. ELECTRICAL APPARATUS. What is electricity?—Forms of electricity—Magnetism—The permanent magnet—Lines of force—Electro-magnets—The electric bell—The induction coil—The condenser—Transformation of current—Uses of the induction coil. WHAT IS ELECTRICITY? OF the ultimate nature of electricity, as of that of heat and light, we are at present ignorant. But it has been clearly established that all three phenomena are but manifestations of the energy pervading the universe. By means of suitable apparatus one form can be converted into another form. The heat of fuel burnt in a boiler furnace develops mechanical energy in the engine which the boiler feeds with steam. The engine revolves a dynamo, and the electric current thereby generated can be passed through wires to produce mechanical motion, heat, or light. We must remain content, therefore, with assuming that electricity is energy or motion transmitted through the ether from molecule to molecule, or from atom to atom, of matter. Scientific investigation has taught us how to produce it at will, how to harness it to our uses, and how to measure it; but not it is. That question may, perhaps, remain unanswered till the end of human history. A great difficulty attending the explanation of electrical action is this—that, except in one or two cases, no comparison can be established between it and the operation of gases and fluids. When dealing with the steam-engine, any ordinary intelligence soon grasps the principles which govern the use of steam in cylinders or turbines. The diagrams show, it is hoped, quite plainly "how it works." But electricity is elusive, invisible; and the greatest authorities cannot say what goes on at the poles of a magnet or on the surface of an electrified body. Even the existence of "negative" and "positive" electricity is problematical. However, we see the effects, and we know that if one thing is done another thing happens; so that we are at least able to use terms which, while convenient, are not at present controverted by scientific progress. what FORMS OF ELECTRICITY. Rub a vulcanite rod and hold one end near some tiny pieces of paper. They fly to it, stick to it for a time, and then fall off. The rod was electrified—that is, its surface was affected in such a way as to be in a state of molecular strain which the contact of the paper fragments alleviated. By rubbing large surfaces and collecting the electricity in suitable receivers the strain can be made to relieve itself in the form of a violent discharge accompanied by a bright flash. This form of electricity is known as . static Next, place a copper plate and a zinc plate into a jar full of diluted sulphuric acid. If a wire be attached to them a current of electricity is said to along the wire. We must not, however, imagine that anything actually moves along inside the wire, as water, steam, or air, passes through a pipe. Professor Trowbridge says, "No other agency for transmitting power can be stopped by such slight obstacles as electricity. A thin sheet of paper placed across a tube conveying compressed air would be instantly ruptured. It would take a wall of steel at least an inch thick to stand the pressure of steam which is driving a 10,000 horse-power engine. A thin layer of dirt beneath the wheels of an electric car can prevent the current which propels the car from passing to the rail, and then back to the power-house." There would, indeed, be a puncture of the paper if the current had a sufficient voltage, or pressure; yet the fact remains that electricity can be very easily confined to its conductor by means of some insulating or nonconducting envelope. flow current MAGNETISM. The most familiar form of electricity is that known as magnetism. When a bar of steel or iron is magnetized, it is supposed that the molecules in it turn and arrange themselves with all their north-seeking poles towards the one end of the bar, and their south-seeking poles towards the other. If the bar is balanced freely on a pivot, it comes to rest pointing north and south; for, the earth being a huge magnet, its north pole attracts all the north-seeking poles of the molecules, and its south poles the south-seeking poles. (The north- pole of a magnet is marked N., though it is in reality the pole; for unlike poles are mutually attractive, and like poles repellent.) seeking south There are two forms of magnet— and . If steel is magnetized, it remains so; but soft iron loses practically all its magnetism as soon as the cause of magnetization is withdrawn. This is what we should expect; for steel is more closely compacted than iron, and the molecules therefore would be able to turn about more easily. It is fortunate for us that this is so, since on the rapid magnetization and demagnetization of soft iron depends the action of many of our electrical mechanisms. permanent temporary THE PERMANENT MAGNET. Magnets are either (1) straight, in which case they are called bar magnets; or (2) of horseshoe form, as in Figs. 50 and 51. By bending the magnet the two poles are brought close together, and the attraction of both may be exercised simultaneously on a bar of steel or iron. LINES OF FORCE. In Fig. 50 are seen a number of dotted lines. These are called . If you lay a sheet of paper on a horseshoe magnet and sprinkle it with iron dust, you will at once notice how the particles arrange themselves in curves similar in shape to those shown in the illustration. It is supposed (it cannot be ) that magnetic force streams away from the N. pole and describes a circular course through the air back to the S. pole. The same remark applies to the bar magnet. lines of magnetic force proved ELECTRICAL MAGNETS. If an insulated wire is wound round and round a steel or iron bar from end to end, and has its ends connected to the terminals of an electric battery, current rotates round the bar, and the bar is magnetized. By increasing the strength and volume of the current, and multiplying the number of turns of wire, the attractive force of the magnet is increased. Now disconnect the wires from the battery. If of iron, the magnet at once loses its attractive force; but if of steel, it retains it in part. Instead of a simple horseshoe-shaped bar, two shorter bars riveted into a plate are generally used for electromagnets of this type. Coils of wire are wound round each bar, and connected so as to form one continuous whole; but the wire of one coil is wound in the direction opposite to that of the other. The free end of each goes to a battery terminal. In Fig. 51 you will notice that some of the "lines of force" are deflected through the iron bar a. They pass more easily through iron than through air; and will choose iron by preference. The attraction exercised by a magnet on iron may be due to the effort of the lines of force to shorten their paths. It is evident that the closer a comes to the poles of the magnet the less will be the distance to be travelled from one pole to the bar, along it, and back to the other pole. Having now considered electricity in three of its forms—static, current, and rotatory—we will pass to some of its applications. THE ELECTRIC BELL. In Fig. 52 we have a diagrammatic view of an electric bell and current. When the bell-push is pressed in, current flows from the battery to terminal t1, round the electro-magnet m, through the pillar p and flat steel springs s and b, through the platinum-pointed screw, and back to the battery through the push. The circulation of current magnetizes m, which attracts the iron armature a attached to the spring s, and draws the hammer h towards the gong. Just before the stroke occurs, the spring b leaves the tip of the screw, and the circuit is broken, so that the magnet no longer attracts. h is carried by its momentum against the gong, and is withdrawn by the spring, until b once more makes contact, and the magnet is re-excited. The hammer vibrations recur many times a second as long as the push is pressed in. The electric bell is used for so many purposes that they cannot all be noted. It plays an especially important part in telephonic installations to draw the attention of the subscribers, forms an item in automatic fire and burglar alarms, and is a necessary adjunct of railway signalling cabins. THE INDUCTION OR RUHMKORFF COIL. Reference was made in connection with the electrical ignition of internal-combustion engines ( ) to the . This is a device for increasing the , or pressure, of a current. The two-cell accumulator carried in a motor car gives a voltage (otherwise called electro-motive force = E.M.F.) of 4·4 volts. If you attach a wire to one terminal of the accumulator and brush the loose end rapidly across the other terminal, you will notice that a bright spark passes between the wire and the terminal. In reality there are two sparks, one when they touch, and another when they separate, but they occur so closely together that the eye cannot separate the two impressions. A spark of this kind would not be sufficiently hot to ignite a charge in a motor cylinder, and a spark from the induction coil is therefore used. p. 101 induction coil voltage We give a sketch of the induction coil in Fig. 53. It consists of a core of soft iron wires round which is wound a layer of coarse insulated wire, denoted by the thick line. One end of the winding of this coil is attached to the battery, the other to the base of a hammer, h, vibrating between the end of the core and a screw, s, passing through an upright, t, connected with the other terminal of the battery. The action of the hammer is precisely the same as that of the armature of an electric bell. Outside the primary coil are wound many turns of a much finer wire completely insulated from the primary coil. The ends of this coil are attached to the objects (in the case of a motor car, the insulated wire of the sparking-plug and a wire projecting from its outer iron casing) between which a spark has to pass. As soon as h touches s the circuit is completed. The core becomes a powerful magnet with external lines of force passing from one pole to the other over and among the turns of the secondary coil. h is almost instantaneously attracted by the core, and the break occurs. The lines of force now (at least so it is supposed) sink into the core, cutting through the turns of the "secondary," and causing a powerful current to flow through them. The greater the number of turns, the greater the number of times the lines of force are cut, and the stronger is the current. If sufficiently intense, it jumps any gap in the secondary circuit, heating the intermediate air to a state of incandescence. primary secondary THE CONDENSER. The sudden parting of h and s would produce strong sparking across the gap between them if it were not for the condenser, which consists of a number of tinfoil sheets separated by layers of paraffined paper. All the "odd" sheets are connected with t, all the "even" with t1. Now, the more rapid the extinction of magnetism in the core after "break" of the primary circuit, the more rapidly will the lines of force collapse, and the more intense will be the induced current in the secondary coil. The condenser diminishes the period of extinction very greatly, while lengthening the period of magnetization after the "make" of the primary current, and so decreasing the strength of the reverse current. TRANSFORMATION OF CURRENT. The difference in the voltage of the primary and secondary currents depends on the length of the windings. If there are 100 turns of wire in the primary, and 100,000 turns in the secondary, the voltage will be increased 1,000 times; so that a 4-volt current is "stepped up" to 4,000 volts. In the largest induction coils the secondary winding absorbs 200–300 miles of wire, and the spark given may be anything up to four feet in length. Such a spark would pierce a glass plate two inches thick. It must not be supposed that an induction coil increases the of current given off by a battery. It merely increases its pressure at the expense of its volume—stores up its energy, as it were, until there is enough to do what a low-tension flow could not effect. A fair comparison would be to picture the energy of the low-tension current as the momentum of a number of small pebbles thrown in succession at a door, say 100 a minute. If you went on pelting the door for hours you might make no impression on it, but if you could knead every 100 pebbles into a single stone, and throw these stones one per minute, you would soon break the door in. amount Any intermittent current can be transformed as regards its intensity. You may either increase its pressure while decreasing its rate of flow, or ; or decrease its pressure and increase its flow. In the case that we have considered, a continuous battery current is rendered intermittent by a mechanical contrivance. But if the current comes from an "alternating" dynamo—that is, is already intermittent—the contact-breaker is not needed. There will be more to say about transformation of current in later paragraphs. amperage USES OF THE INDUCTION COIL. The induction coil is used—(1.) For passing currents through glass tubes almost exhausted of air or containing highly rarefied gases. The luminous effects of these "Geissler" tubes are very beautiful. (2.) For producing the now famous X or Röntgen rays. These rays accompany the light rays given off at the negative terminal (cathode) of a vacuum tube, and are invisible to the eye unless caught on a fluorescent screen, which reduces their rate of vibration sufficiently for the eye to be sensitive to them. The Röntgen rays have the peculiar property of penetrating many substances quite opaque to light, such as metals, stone, wood, etc., and as a consequence have proved of great use to the surgeon in localizing or determining the nature of an internal injury. They also have a deterrent effect upon cancerous growths. (3.) In wireless telegraphy, to cause powerful electric oscillations in the ether. (4.) On motor cars, for igniting the cylinder charges. (5.) For electrical massage of the body. About HackerNoon Book Series: We bring you the most important technical, scientific, and insightful public domain books.
