The Useless Skills You're Still Learning 

RateX Goes Live on Solana Mainnet on 17th Oct 2024. RateX, the world’s first leveraged yield exchange, has officially launched on the Solana mainnet, marking a significant milestone in the decentralized finance (DeFi) space. Built with innovation at its core, RateX enables users to trade synthetic yield tokens (YT) of various yield-bearing assets (YBA) with leverage of up to 10x. This powerful platform introduces groundbreaking solutions to maximize capital efficiency while addressing common DeFi challenges, such as impermanent loss and limited yield-trading opportunities. RateX, a proud recipient of a grant from the Solana Foundation and the first-place winner of the Solana Renaissance Hackathon (MCM), aims to push the boundaries of decentralized finance. The platform’s unique value proposition comes from its use of synthetic yield tokens, which track the yield of different assets and allow traders to take positions with leveraged exposure. This gives users more flexibility and opportunities to capitalize on fluctuations in yields, empowering them to generate higher returns on their investments. The introduction of RateX also brings a cutting-edge Time-Decaying Automated Market Maker (AMM) to the forefront. This AMM is designed to improve capital efficiency while reducing the risks traditionally associated with liquidity provisioning, particularly in expiring contracts. The mechanism minimizes the potential for impermanent loss—a common issue for liquidity providers (LPs) in volatile markets—and aims to eventually eliminate it altogether. As a result, RateX offers a more robust and rewarding environment for both traders and liquidity providers. In addition to its leveraged yield trading capabilities, RateX caters to users looking for stability by providing fixed-yield options. These options allow users to lock in specific yields over a predetermined period, offering more predictable returns compared to the highly variable DeFi market. Whether traders are seeking high-risk, high-reward opportunities or more stable, consistent gains, RateX provides an ecosystem that accommodates diverse trading strategies. Key Partnerships with Jupiter and Jito Further bolstering its platform, RateX has announced strategic partnerships with two prominent players in the Solana ecosystem—Jupiter and Jito. These partnerships not only strengthen RateX’s technological infrastructure but also extend its reach within the DeFi and staking communities. Jupiter, one of the largest decentralized trading platforms on Solana, is known for its high liquidity and strong governance framework. With an extensive community and a focus on enabling smooth cross-asset trading, Jupiter plays a pivotal role in bringing liquidity to the RateX platform. This partnership ensures that RateX users will benefit from deep liquidity pools, efficient price discovery, and seamless execution of trades. Jupiter’s active governance community also opens the door for collaborative development efforts, allowing RateX to evolve in line with community-driven innovations. On the staking side, RateX has joined forces with Jito, the leading liquid staking platform on Solana. Jito’s expertise in liquid staking will enhance RateX’s offerings by providing users with access to staking-derived yield-bearing assets. By leveraging Jito’s technology, RateX can integrate liquid staking into its synthetic yield ecosystem, offering even more diverse options for traders to earn yield. With this partnership, users can expect enhanced staking efficiency, better capital utilization, and a broader range of yield-bearing assets available for leveraged trading. A New Era for DeFi: RateX as a Pillar of Infrastructure The launch of RateX comes at a time when the DeFi sector is evolving rapidly, and the demand for more sophisticated financial products is higher than ever. By pioneering leveraged yield trading and forming key partnerships with Jupiter and Jito, RateX is positioning itself as a crucial pillar of the Solana ecosystem and DeFi infrastructure at large. RateX’s mission is to redefine how yield movements are traded, making the entire process more efficient, transparent, and accessible to both seasoned traders and new entrants to the space. As the world’s first leveraged yield exchange, RateX is primed to play a central role in shaping the next phase of decentralized finance, often referred to as the “next DeFi summer.” With its innovative platform, strong partnerships, and focus on capital efficiency, RateX is setting the stage for a new era of financial freedom and opportunities for DeFi enthusiasts worldwide.

Off on a Comet! a Journey through Planetary Space by Jules Verne, is part of the HackerNoon Books Series. You can jump to any chapter in this book . FAR INTO SPACE here CHAPTER X. FAR INTO SPACE A month passed away. Gallia continued its course, bearing its little population onwards, so far removed from the ordinary influence of human passions that it might almost be said that its sole ostensible vice was represented by the greed and avarice of the miserable Jew. After all, they were but making a voyage—a strange, yet a transient, excursion through solar regions hitherto untraversed; but if the professor’s calculations were correct—and why should they be doubted?—their little vessel was destined, after a two years’ absence, once more to return “to port.” The landing, indeed, might be a matter of difficulty; but with the good prospect before them of once again standing on terrestrial shores, they had nothing to do at present except to make themselves as comfortable as they could in their present quarters. Thus confident in their anticipations, neither the captain, the count, nor the lieutenant felt under any serious obligation to make any extensive provisions for the future; they saw no necessity for expending the strength of the people, during the short summer that would intervene upon the long severity of winter, in the cultivation or the preservation of their agricultural resources. Nevertheless, they often found themselves talking over the measures they would have been driven to adopt, if they had found themselves permanently attached to their present home. Even after the turning-point in their career, they knew that at least nine months would have to elapse before the sea would be open to navigation; but at the very first arrival of summer they would be bound to arrange for the and the to retransport themselves and all their animals to the shores of Gourbi Island, where they would have to commence their agricultural labors to secure the crops that must form their winter store. During four months or thereabouts, they would lead the lives of farmers and of sportsmen; but no sooner would their haymaking and their corn harvest have been accomplished, than they would be compelled again, like a swarm of bees, to retire to their semi-troglodyte existence in the cells of Nina’s Hive. Dobryna Hansa Now and then the captain and his friends found themselves speculating whether, in the event of their having to spend another winter upon Gallia, some means could not be devised by which the dreariness of a second residence in the recesses of the volcano might be escaped. Would not another exploring expedition possibly result in the discovery of a vein of coal or other combustible matter, which could be turned to account in warming some erection which they might hope to put up? A prolonged existence in their underground quarters was felt to be monotonous and depressing, and although it might be all very well for a man like Professor Rosette, absorbed in astronomical studies, it was ill suited to the temperaments of any of themselves for any longer period than was absolutely indispensable. One contingency there was, almost too terrible to be taken into account. Was it not to be expected that the time might come when the internal fires of Gallia would lose their activity, and the stream of lava would consequently cease to flow? Why should Gallia be exempt from the destiny that seemed to await every other heavenly body? Why should it not roll onwards, like the moon, a dark cold mass in space? In the event of such a cessation of the volcanic eruption, whilst the comet was still at so great a distance from the sun, they would indeed be at a loss to find a substitute for what alone had served to render life endurable at a temperature of 60 degrees below zero. Happily, however, there was at present no symptom of the subsidence of the lava’s stream; the volcano continued its regular and unchanging discharge, and Servadac, ever sanguine, declared that it was useless to give themselves any anxiety upon the matter. On the 15th of December, Gallia was 276,000,000 leagues from the sun, and, as it was approximately to the extremity of its axis major, would travel only some 11,000,000 or 12,000,000 leagues during the month. Another world was now becoming a conspicuous object in the heavens, and Palmyrin Rosette, after rejoicing in an approach nearer to Jupiter than any other mortal man had ever attained, was now to be privileged to enjoy a similar opportunity of contemplating the planet Saturn. Not that the circumstances were altogether so favorable. Scarcely 31,000,000 miles had separated Gallia from Jupiter; the minimum distance of Saturn would not be less than 415,000,000 miles; but even this distance, although too great to affect the comet’s progress more than had been duly reckoned on, was considerably shorter than what had ever separated Saturn from the earth. To get any information about the planet from Rosette appeared quite impossible. Although equally by night and by day he never seemed to quit his telescope, he did not evince the slightest inclination to impart the result of his observations. It was only from the few astronomical works that happened to be included in the library that any details could be gathered, but these were sufficient to give a large amount of interesting information. Dobryna’s Ben Zoof, when he was made aware that the earth would be invisible to the naked eye from the surface of Saturn, declared that he then, for his part, did not care to learn any more about such a planet; to him it was indispensable that the earth should remain in sight, and it was his great consolation that hitherto his native sphere had never vanished from his gaze. At this date Saturn was revolving at a distance of 420,000,000 miles from Gallia, and consequently 874,440,000 miles from the sun, receiving only a hundredth part of the light and heat which that luminary bestows upon the earth. On consulting their books of reference, the colonists found that Saturn completes his revolution round the sun in a period of 29 years and 167 days, traveling at the rate of more than 21,000 miles an hour along an orbit measuring 5,490 millions of miles in length. His circumference is about 220,000 miles; his superficies, 144,000 millions of square miles; his volume, 143,846 millions of cubic miles. Saturn is 735 times larger than the earth, consequently he is smaller than Jupiter; in mass he is only 90 times greater than the earth, which gives him a density less than that of water. He revolves on his axis in 10 hours 29 minutes, causing his own year to consist of 86,630 days; and his seasons, on account of the great inclination of his axis to the plane of his orbit, are each of the length of seven terrestrial years. Although the light received from the sun is comparatively feeble, the nights upon Saturn must be splendid. Eight satellites—Mimas, Enceladus, Tethys, Dione, Rhea, Titan, Hyperion, and Japetus—accompany the planet; Mimas, the nearest to its primary, rotating on its axis in 22 1/2 hours, and revolving at a distance of only 120,800 miles, whilst Japetus, the most remote, occupies 79 days in its rotation, and revolves at a distance of 2,314,000 miles. Another most important contribution to the magnificence of the nights upon Saturn is the triple ring with which, as a brilliant setting, the planet is encompassed. To an observer at the equator, this ring, which has been estimated by Sir William Herschel as scarcely 100 miles in thickness, must have the appearance of a narrow band of light passing through the zenith 12,000 miles above his head. As the observer, however, increases his latitude either north or south, the band will gradually widen out into three detached and concentric rings, of which the innermost, dark though transparent, is 9,625 miles in breadth; the intermediate one, which is brighter than the planet itself, being 17,605 miles broad; and the outer, of a dusky hue, being 8,660 miles broad. Such, they read, is the general outline of this strange appendage, which revolves in its own plane in 10 hours 32 minutes. Of what matter it is composed, and how it resists disintegration, is still an unsettled question; but it might almost seem that the Designer of the universe, in permitting its existence, had been willing to impart to His intelligent creatures the manner in which celestial bodies are evolved, and that this remarkable ring-system is a remnant of the nebula from which Saturn was himself developed, and which, from some unknown cause, has become solidified. If at any time it should disperse, it would either fall into fragments upon the surface of Saturn, or the fragments, mutually coalescing, would form additional satellites to circle round the planet in its path. To any observer stationed on the planet, between the extremes of lat. 45 degrees on either side of the equator, these wonderful rings would present various strange phenomena. Sometimes they would appear as an illuminated arch, with the shadow of Saturn passing over it like the hour-hand over a dial; at other times they would be like a semi-aureole of light. Very often, too, for periods of several years, daily eclipses of the sun must occur through the interposition of this triple ring. Truly, with the constant rising and setting of the satellites, some with bright discs at their full, others like silver crescents, in quadrature, as well as by the encircling rings, the aspect of the heavens from the surface of Saturn must be as impressive as it is gorgeous. Unable, indeed, the Gallians were to realize all the marvels of this strange world. After all, they were practically a thousand times further off than the great astronomers have been able to approach by means of their giant telescopes. But they did not complain; their little comet, they knew, was far safer where it was; far better out of the reach of an attraction which, by affecting their path, might have annihilated their best hopes. The distances of several of the brightest of the fixed stars have been estimated. Amongst others, Vega in the constellation Lyra is 100 millions of millions of miles away; Sirius in Canis Major, 123 millions of millions; the Pole-star, 282 millions of millions; and Capella, 340 millions of millions of miles, a figure represented by no less than fifteen digits. The hard numerical statement of these enormous figures, however, fails altogether in any adequate way to convey a due impression of the magnitude of these distances. Astronomers, in their ingenuity, have endeavored to use some other basis, and have found “the velocity of light” to be convenient for their purpose. They have made their representations something in this way: “Suppose,” they say, “an observer endowed with an infinite length of vision: suppose him stationed on the surface of Capella; looking thence towards the earth, he would be a spectator of events that had happened seventy years previously; transport him to a star ten times distant, and he will be reviewing the terrestrial sphere of 720 years back; carry him away further still, to a star so remote that it requires something less than nineteen centuries for light to reach it, and he would be a witness of the birth and death of Christ; convey him further again, and he shall be looking upon the dread desolation of the Deluge; take him away further yet (for space is infinite), and he shall be a spectator of the Creation of the spheres. History is thus stereotyped in space; nothing once accomplished can ever be effaced.” Who can altogether be astonished that Palmyrin Rosette, with his burning thirst for astronomical research, should have been conscious of a longing for yet wider travel through the sidereal universe? With his comet now under the influence of one star, now of another, what various systems might he not have explored! what undreamed-of marvels might not have revealed themselves before his gaze! The stars, fixed and immovable in name, are all of them in motion, and Gallia might have followed them in their un-tracked way. But Gallia had a narrow destiny. She was not to be allowed to wander away into the range of attraction of another center; nor to mingle with the star clusters, some of which have been entirely, others partially resolved; nor was she to lose herself amongst the 5,000 nebulae which have resisted hitherto the grasp of the most powerful reflectors. No; Gallia was neither to pass beyond the limits of the solar system, nor to travel out of sight of the terrestrial sphere. Her orbit was circumscribed to little over 1,500 millions of miles; and, in comparison with the infinite space beyond, this was a mere nothing.

An excellent account of Airy's career

JUnit is one of the most popular testing frameworks for the Java programming language. It has also been important in the development of Test Driven Development, or TDD. In 2018, the latest version of this framework was released, JUnit5, and many programmers who use the JUnit platform have had to decide whether or not to refactor their existing code that is written in a previous version of JUnit. <tl;dr> This article is about mixing JUnit4 and JUnit5 into your ongoing project to get JUnit5 benefits without refactoring all already written JUnit4 tests. The intention is not to describe JUnit5 in depth but give a guideline to migrate JUnit5 support. JUnit5 has many benefits that developers will want to use. Better exception handling, better parameterized tests, multiple and so on. If you are like me, and want to migrate into a newer platform as soon as possible, you probably also know what a pain it is to do so. testrunners Fortunately, JUnit5 has very good support to work side by side with version 4. I think this is important in projects where there are hundreds of already written tests. To refactor all of them is enormous work and it is much easier to give up than go on with adopting something new. In the following post, I’ve broken down the steps you will need to follow in order to introduce JUtin5 support for tests, while still supporting JUnit4 tests. Lets assume we have project gradle plugins {id 'java'id 'com.adarshr.test-logger' version '1.6.0'} group 'rainoko'version '1.0-SNAPSHOT' sourceCompatibility = 11 repositories {mavenCentral()} dependencies {testCompile('junit:junit:4.12')} wrapper {gradleVersion = '5.2.1'} with some simple class SimpleNaturalCalculator.java package ee.rainoko.junit5demo; public class SimpleNaturalCalculator {public int addition(int arg1, int arg2) {return arg1 + arg2;} public int substraction(int arg1, int arg2) {return arg1 - arg2;} public int multiplication(int arg1, int arg2) {return arg1 * arg2;} public int division(int arg1, int arg2) {return arg1 / arg2;}} And covered with test SimpleNaturalCalculatorTest.java package ee.rainoko.junit5demo; import org.junit.*; import static org.junit.Assert.*; public class SimpleNaturalCalculatorJunit4Test {@Testpublic void shouldAdd() {SimpleNaturalCalculator calculator = new SimpleNaturalCalculator(); int result = calculator.addition(1, 2);  

_assertEquals_(3, result); } @Testpublic void shouldSubstract() {SimpleNaturalCalculator calculator = new SimpleNaturalCalculator(); int result = calculator.substraction(1, 2);  

_assertEquals_(-1, result); } @Testpublic void shouldMultiply() {SimpleNaturalCalculator calculator = new SimpleNaturalCalculator(); int result = calculator.multiplication(1, 2);  

_assertEquals_(2, result); } @Testpublic void shouldDivide() {SimpleNaturalCalculator calculator = new SimpleNaturalCalculator(); int result = calculator.division(1, 2);  

_assertEquals_(0, result); }} As we see this is a JUnit4 test using annotations from org.junit Lets run this with the following command: gradlew test And we get this result: ee.rainoko.junit5demo.SimpleNaturalCalculatorTest Test shouldAdd PASSEDTest shouldDivide PASSEDTest shouldSubstract PASSEDTest shouldMultiply PASSED Now we have been setting up a standard project with JUnit4. Lets proceed. Our goal is to introduce JUnit5 support. Unlike version 4 the 5 has modularized library structure: [https://junit.org/junit5/docs/current/user-guide/] JUnit 5 = + + JUnit Platform JUnit Jupiter JUnit Vintage The serves as a foundation for on the JVM. [https://junit.org/junit5/docs/current/user-guide/] JUnit Platform launching testing frameworks is the combination of the new and for writing tests and extensions in JUnit 5. [https://junit.org/junit5/docs/current/user-guide/] JUnit Jupiter programming model extension model provides a for running JUnit 3 and JUnit 4 based tests on the platform.[https://junit.org/junit5/docs/current/user-guide/] JUnit Vintage TestEngine Now knowing that, lets add JUnit5 support. For starters, to prevent confusion, lets rename our junit4 test class to SimpleNaturalCalculatorJunit4Test.java Lets add JUnit5 dependencies to gradle // JUnit JupitertestImplementation('org.junit.jupiter:junit-jupiter:5.4.0') // JUnit VintagetestCompileOnly('junit:junit:4.12')testRuntimeOnly('org.junit.vintage:junit-vintage-engine:5.4.0') {because 'allows JUnit 3 and JUnit 4 tests to run'} As you see we added junit-jupiter. Also marked junit:4.12 as testCompileOnly. This library is still needed for compilation if we want to have our old junit4 tests without any modification. And then we also added junit-vintage-engine to give junit platform ability to run JUnit4 tests side by side with JUnit5 tests. Finally we need to add also command to use JUnit5 platform for running tests in gradle test {useJUnitPlatform()} No lets add JUnit5 test class SimpleNaturalCalculatorJunit5Test.java package ee.rainoko.junit5demo; import org.junit.jupiter.api.Test; import static org.junit.jupiter.api.Assertions. ; assertEquals class SimpleNaturalCalculatorJunit5Test {@Testvoid shouldAdd() {SimpleNaturalCalculator calculator = new SimpleNaturalCalculator(); int result = calculator.addition(1, 2);  

_assertEquals_(3, result); } @Testvoid shouldSubstract() {SimpleNaturalCalculator calculator = new SimpleNaturalCalculator(); int result = calculator.substraction(1, 2);  

_assertEquals_(-1, result); } @Testvoid shouldMultiply() {SimpleNaturalCalculator calculator = new SimpleNaturalCalculator(); int result = calculator.multiplication(1, 2);  

_assertEquals_(2, result); } @Testvoid shouldDivide() {SimpleNaturalCalculator calculator = new SimpleNaturalCalculator(); int result = calculator.division(1, 2);  

_assertEquals_(0, result); }} As you can confirm from imports we now use junit jupiter. Notice that test class is package-protected and methods also. JUnit5 now allows us to use package-protected modifiers, which, as I think, better exposes the purpose of access modifiers of java. Lets run our tests gradlew test And we have output ee.rainoko.junit5demo.SimpleNaturalCalculatorJunit4Test Test shouldAdd PASSEDTest shouldDivide PASSEDTest shouldSubstract PASSEDTest shouldMultiply PASSED ee.rainoko.junit5demo.SimpleNaturalCalculatorJunit5Test Test shouldAdd() PASSEDTest shouldDivide() PASSEDTest shouldSubstract() PASSEDTest shouldMultiply() PASSED We can even use mixed test class. package ee.rainoko.junit5demo; import static org.junit.jupiter.api.Assertions. ; assertEquals public class SimpleNaturalCalculatorJunitMixedTest {@org.junit.Testpublic void shouldAddJunit4() {SimpleNaturalCalculator calculator = new SimpleNaturalCalculator(); int result = calculator.addition(1, 2);

_assertEquals_(0, result); } @org.junit.jupiter.api.Testvoid shouldDivideJunit5() {SimpleNaturalCalculator calculator = new SimpleNaturalCalculator(); int result = calculator.division(1, 2);  

_assertEquals_(0, result); }} As you can see now we have annotations from org.junit and from org.junit.jupiter.api. The JUnit5 platform chooses right engine for each test method. You can even mix asserts from old JUnit4 package and new JUnit5 package in either of test type. gradlew test And we get output ee.rainoko.junit5demo.SimpleNaturalCalculatorJunit4Test Test shouldAdd PASSEDTest shouldDivide PASSEDTest shouldSubstract PASSEDTest shouldMultiply PASSED ee.rainoko.junit5demo.SimpleNaturalCalculatorJunitMixedTest Test shouldAddJunit4 PASSEDTest shouldDivideJunit4 PASSEDTest shouldMultiplyJunit4 PASSEDTest shouldSubstractJunit4 PASSED ee.rainoko.junit5demo.SimpleNaturalCalculatorJunit5Test Test shouldAdd() PASSEDTest shouldDivide() PASSEDTest shouldSubstract() PASSEDTest shouldMultiply() PASSED ee.rainoko.junit5demo.SimpleNaturalCalculatorJunitMixedTest Test shouldAddJunit5() PASSEDTest shouldDivideJunit5() PASSEDTest shouldMultiplyJunit5() PASSEDTest shouldSubstractJunit5() PASSED SUCCESS: Executed 16 tests in 1s JUnit4 and JUnit5 have different @Before… annotations. If you need to mix them add both annotations to your setUp and tearDown methods. Be aware Hope this article helpt to migrate to JUnit5 even if your project using heavily JUnit4 tests and . get benefits now not tomorrow Read more There are plenty of good examples and articles about JUnit5.
