Empirical Test of the Rafting Hypothesis

first_imgEvolutionists claim large mammals like monkeys made it across oceans on rafts of vegetation. Here was a chance to test the idea.“This has turned out to be one of the biggest, unplanned, natural experiments in marine biology, perhaps in history,” said co-author John Chapman of Oregon State University. —Science DailyThe earthquake that struck Japan in 2011 created one of the biggest tsunamis in recorded history. Television viewers watched in horror as whole towns were inundated and large fields of debris were swept out to sea. Awful as it was, it provided a test of a hypothesis that evolutionists use to overcome problems with biogeography. New World monkeys, for instance, are similar to the ones in Africa, but how did they get there? They could not have evolved separately, Darwinians say, so they must have crossed the Atlantic on rafts of debris (4/27/15).In Science Magazine, Carlton et al observed what happened to debris after the Japan tsunami. In “Tsunami-driven rafting: Transoceanic species dispersal and implications for marine biogeography,” they say:The 2011 East Japan earthquake generated a massive tsunami that launched an extraordinary transoceanic biological rafting event with no known historical precedent. We document 289 living Japanese coastal marine species from 16 phyla transported over 6 years on objects that traveled thousands of kilometers across the Pacific Ocean to the shores of North America and Hawai’i. Most of this dispersal occurred on nonbiodegradable objects, resulting in the longest documented transoceanic survival and dispersal of coastal species by rafting. Expanding shoreline infrastructure has increased global sources of plastic materials available for biotic colonization and also interacts with climate change–induced storms of increasing severity to eject debris into the oceans. In turn, increased ocean rafting may intensify species invasions.Plastic should have provided a better opportunity for transport because of its longer half-life:Rafted anthropogenic debris also differs strikingly from natural rafts. Natural long-distance ocean rafting consists of largely ephemeral, dissolvable, or decomposable materials, including biodegradable terrestrial vegetation (trees, root masses, and seeds) and pumice, all with far shorter at-sea half-lives than fiberglass, polystyrene, and polyvinyl chloride–based objects. Despite the tsunami-induced loss of large expanses of forests on the northeast Honshu coast, few stranded Japanese trees, typically with few attached species, were observed in North America or Hawai’i. Most trees may have stayed on land or washed ashore in Japan, or may have sunk before undergoing or completing ocean transit. Further, building wood, which had commenced arrival in large quantities in 2013 (also with relatively few species) (Fig. 3A), largely tapered off by 2014 (Fig. 2 and fig. S2). This highly constrained, largely 2- to 3-year (2011 to 2014) at-sea existence of wooden JTMD [Japanese tsunami marine debris] is due in large part to destruction by wood-destroying teredinid mollusks (shipworms) [(5) and Fig. 1D]. Perhaps not surprisingly, then, before 2012 there are no reports of Western Pacific vegetation or wood arriving with communities of living Japanese species in either the Hawaiian Islands or North America, despite >150 years of shore observations by scientists, suggesting that such events are rare.The Japanese tsunami, with its abundant plastic rafts, sounds like a huge opportunity for biological transport. There are two problems with applying this prehistorically, however: (1) there was no plastic in the ancient world, and (2) the largest animals were small. “Five invertebrate groups (mollusks, annelids, cnidarians, bryozoans, and crustaceans) composed 85% of the species diversity of macrobiota,” they say. Most of these are already marine-adapted creatures (2/13/16). No monkeys or other land vertebrates took the tsunami express. Not even ants used it (11/04/16).If empirical evidence counts for anything, these results should constitute strong falsification of the rafting hypothesis for large animals. Under ideal conditions, only small marine animals crossed the oceans, and that on man-made, non-biodegradable things like plastic. How much less could monkeys ride on natural rafts?

Open webOS 10 is ready to serve

first_img The webOS team also issued an exuberant news flash, on the heels of the 1.0 release announcement, saying that Open webOS has been successfully ported to a Google Nexus phone. This phone port is still, however, a work in progress. Tom King of webOS-Ports said they are working on getting hardware acceleration.The 1.0 release has Enyo 2 support. Enyo is a JavaScript app framework “You can now take apps built on one of the best cross-platform JavaScript frameworks and easily run these same apps on Open webOS or other platforms,” according to the announcement in the Open webOS blog. HP to make webOS software public by September Citation: Open webOS 1.0 is ready to serve (2012, September 30) retrieved 18 August 2019 from https://phys.org/news/2012-09-webos-ready.html (Phys.org)—Open webOS, formerly HP webOS, the mobile operating system that was initially developed by Palm, which HP acquired, was let out the door this week as Open webOS 1.0. The good news is that Open webOS can now be ported to new devices, according to the announcement. An OpenEmbedded build runs inside an OE emulator. Core apps that accompany the 1.0 release include e-mail and web browsing. The team behind the release says that there are 75 different components.

Earlier this year, Enyo was open sourced under the Apache 2.0 license. The team focused on porting Enyo to work with iOS, Android, Safari, Firefox, Chrome, and IE8. Enyo 2.0 includes a cross-platform UI toolkit, and a layout library that supports multi-form factor application designs for building apps.Open webOS, though, still has a stay-tuned sign out for developers. The team behind it aim to cover an aggressive to-do list. In the works, they said, are integration for Qt5 and WebKit2 development tools, and compatibility with ConnMan network management. The ConnMan project provides a daemon for managing Internet connections in embedded devices running Linux. Also planned are enhancements including open sourced media and audio components and the Bluez Bluetooth stack. The Bluez is the Bluetooth stack for Linux. It was initially developed by Qualcomm and is available for Linux kernel versions 2.4.6 and up.According to the team blog, “How long it will take for those additions to come along isn’t clear just yet, but HP is definitely taking their commitment to webOS seriously, and hopes the community will as well.” They said, “We expect to have more Open webOS port announcements in the future and will work with the community to deliver updates.” Developers can explore the release further by going to the Open webOS repositories on GitHub.Steve Winston, chief architect, webOS, performed a video demo earlier this week, running the operating system on an HP PC.last_img read more

US Issues New Rules on Small LowAltitude Commercial Drones

first_img Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global 3 min read Register Now » In a move that stopped short of allowing package deliveries by unmanned aircraft, the Obama administration unveiled landmark rules on Tuesday that will open the skies for low-level small drones for education, research and routine commercial use.The use of drones for deliveries from companies like Amazon.com Inc. and Alphabet Inc., however, will require separate regulation.The head of the U.S. Federal Aviation Administration, Michael Huerta, declined to offer a timetable on when the separate rules for deliveries would be written. Both Amazon and Google have said they plan to start using drones to deliver goods ordered online by 2017.Commercial drone operations have been illegal in the United States without a waiver from the FAA.Under the new rules, drone flights will be approved for agriculture, research and development, educational and academic use, and powerline, pipeline and antenna inspections. They will also be approved for aiding rescue operations, bridge inspections, aerial photography and wildlife nesting area evaluations.The rules, which will take effect in late August, will allow drones that weigh less than 55 pounds and fly up to 400 feet high and 100 miles per hour, but only within sight of an operator and not over people.Drones will not be allowed to fly at night unless they have special lighting and must stay at least 5 miles from airports.Operators must be at least 16 and have a remote pilot certificate. They also must report to the FAA on any drone incident that results in serious injuries or property damage.”As this new technology continues to grow and develop, we want to make sure we strike the right balance between innovation and safety,” Transportation Secretary Anthony Foxx said on a call with reporters.Sen. Mark Warner, a Virginia Democrat, said the government needs to move quickly. “We need to be looking at how we can safely integrate drones into American airspace, both right now and for the future. That said, we still lag behind many other countries in adopting this technology.”The White House says unmanned aircraft could lead to $82 billion in economic growth by 2025 and support up to 100,000 jobs.The detailed rules are laid out in a 642-page regulation. But drone flights will still remain banned in Washington, DC, because of security restrictions imposed by Congress.The White House noted that the U.S. Interior Department has used unmanned aircraft systems since 2009 in conducting wildlife and vegetation surveys to protect endangered populations and wildfire management.The FAA in December announced rules requiring registration of drones weighing more than 0.55 pound and less than 55 pounds, including payloads such as on-board cameras.(Reporting by David Shepardson and Ayesha Rascoe; Editing by Marguerita Choy and Dan Grebler) Growing a business sometimes requires thinking outside the box.

Design a RESTful web API with Java Tutorial

first_imgIn today’s tutorial, you will learn to design REST services. We will break down the key design considerations you need to make when building RESTful web APIs. In particular, we will focus on the core elements of the REST architecture style: Resources and their identifiers Interaction semantics for RESTful APIs (HTTP methods) Representation of resources Hypermedia controls This article is an excerpt from a book written by Balachandar Bogunuva Mohanram, titled RESTful Java Web Services, Second Edition. This book will help you build robust, scalable and secure RESTful web services, making use of the JAX-RS and Jersey framework extensions. Let’s start by discussing the guidelines for identifying resources in a problem domain. Richardson Maturity Model—Leonardo Richardson has developed a model to help with assessing the compliance of a service to REST architecture style. The model defines four levels of maturity, starting from level-0 to level-3 as the highest maturity level. The maturity levels are decided considering the aforementioned principle elements of the REST architecture. Identifying resources in the problem domain The basic steps that yoneed to take while building a RESTful web API for a specific problem domain are: Identify all possible objects in the problem domain. This can be done by identifying all the key nouns in the problem domain. For example, if you are building an application to manage employees in a department, the obvious nouns are department and employee. The next step is to identify the objects that can be manipulated using CRUD operations. These objects can be classified as resources. Note that you should be careful while choosing resources. Based on the usage pattern, you can classify resources as top-level and nested resources (which are the children of a top-level resource). Also, there is no need to expose all resources for use by the client; expose only those resources that are required for implementing the business use case. Transforming operations to HTTP methods Once you have identified all resources, as the next step, you may want to map the operations defined on the resources to the appropriate HTTP methods. The most commonly used HTTP methods (verbs) in RESTful web APIs are POST, GET, PUT, and DELETE. Note that there is no one-to-one mapping between the CRUD operations defined on the resources and the HTTP methods. Understanding of idempotent and safe operation concepts will help with using the correct HTTP method. An operation is called idempotent if multiple identical requests produce the same result. Similarly, an idempotent RESTful web API will always produce the same result on the server irrespective of how many times the request is executed with the same parameters; however, the response may change between requests. An operation is called safe if it does not modify the state of the resources. Check out the following table: MethodIdempotentSafeGETYESYESOPTIONSYESYESHEADYESYESPOSTNONOPATCHNONOPUTYESNODELETEYESNO Here are some tips for identifying the most appropriate HTTP method for the operations that you want to perform on the resources: GET: You can use this method for reading a representation of a resource from the server. According to the HTTP specification, GET is a safe operation, which means that it is only intended for retrieving data, not for making any state changes. As this is an idempotent operation, multiple identical GET requests will behave in the same manner. A GET method can return the 200 OK HTTP response code on the successful retrieval of resources. If there is any error, it can return an appropriate status code such as 404 NOT FOUND or 400 BAD REQUEST. DELETE: You can use this method for deleting resources. On successful deletion, DELETE can return the 200 OK status code. According to the HTTP specification, DELETE is an idempotent operation. Note that when you call DELETE on the same resource for the second time, the server may return the 404 NOT FOUND status code since it was already deleted, which is different from the response for the first request. The change in response for the second call is perfectly valid here. However, multiple DELETE calls on the same resource produce the same result (state) on the server. PUT: According to the HTTP specification, this method is idempotent. When a client invokes the PUT method on a resource, the resource available at the given URL is completely replaced with the resource representation sent by the client. When a client uses the PUT request on a resource, it has to send all the available properties of the resource to the server, not just the partial data that was modified within the request. You can use PUT to create or update a resource if all attributes of the resource are available with the client. This makes sure that the server state does not change with multiple PUT requests. On the other hand, if you send partial resource content in a PUT request multiple times, there is a chance that some other clients might have updated some attributes that are not present in your request. In such cases, the server cannot guarantee that the state of the resource on the server will remain identical when the same request is repeated, which breaks the idempotency rule. POST: This method is not idempotent. This method enables you to use the POST method to create or update resources when you do not know all the available attributes of a resource. For example, consider a scenario where the identifier field for an entity resource is generated at the server when the entity is persisted in the data store. You can use the POST method for creating such resources as the client does not have an identifier attribute while issuing the request. Here is a simplified example that illustrates this scenario. In this example, the employeeID attribute is generated on the server: POST hrapp/api/employees HTTP/1.1 Host: packtpub.com {employee entity resource in JSON} On the successful creation of a resource, it is recommended to return the status of 201 Created and the location of the newly created resource. This allows the client to access the newly created resource later (with server-generated attributes). The sample response for the preceding example will look as follows: 201 Created Location: hrapp/api/employees/1001 Best practice Use caching only for idempotent and safe HTTP methods, as others have an impact on the state of the resources. Understanding the difference between PUT and POST A common question that you will encounter while designing a RESTful web API is when you should use the PUT and POST methods? Here’s the simplified answer: You can use PUT for creating or updating a resource, when the client has the full resource content available. In this case, all values are with the client and the server does not generate a value for any of the fields. You will use POST for creating or updating a resource if the client has only partial resource content available. Note that you are losing the idempotency support with POST. An idempotent method means that you can call the same API multiple times without changing the state. This is not true for the POST method; each POST method call may result in a server state change. PUT is idempotent, and POST is not. If you have strong customer demands, you can support both methods and let the client choose the suitable one on the basis of the use case. Naming RESTful web resources Resources are a fundamental concept in RESTful web services. A resource represents an entity that is accessible via the URI that you provide. The URI, which refers to a resource (which is known as a RESTful web API), should have a logically meaningful name. Having meaningful names improves the intuitiveness of the APIs and, thereby, their usability. Some of the widely followed recommendations for naming resources are shown here: It is recommended you use nouns to name both resources and path segments that will appear in the resource URI. You should avoid using verbs for naming resources and resource path segments. Using nouns to name a resource improves the readability of the corresponding RESTful web API, particularly when you are planning to release the API over the internet for the general public. You should always use plural nouns to refer to a collection of resources. Make sure that you are not mixing up singular and plural nouns while forming the REST URIs. For instance, to get all departments, the resource URI must look like /departments. If you want to read a specific department from the collection, the URI becomes /departments/{id}. Following the convention, the URI for reading the details of the HR department identified by id=10 should look like /departments/10. The following table illustrates how you can map the HTTP methods (verbs) to the operations defined for the departments’ resources: ResourceGETPOSTPUTDELETE/departmentsGet all departmentsCreate a new departmentBulk update on departmentsDelete all departments/departments/10Get the HR department with id=10Not allowedUpdate the HR departmentDelete the HR department While naming resources, use specific names over generic names. For instance, to read all programmers’ details of a software firm, it is preferable to have a resource URI of the form /programmers (which tells about the type of resource), over the much generic form /employees. This improves the intuitiveness of the APIs by clearly communicating the type of resources that it deals with. Keep the resource names that appear in the URI in lowercase to improve the readability of the resulting resource URI. Resource names may include hyphens; avoid using underscores and other punctuation. If the entity resource is represented in the JSON format, field names used in the resource must conform to the following guidelines: Use meaningful names for the properties Follow the camel case naming convention: The first letter of the name is in lowercase, for example, departmentName The first character must be a letter, an underscore (_), or a dollar sign ($), and the subsequent characters can be letters, digits, underscores, and/or dollar signs Avoid using the reserved JavaScript keywords If a resource is related to another resource(s), use a subresource to refer to the child resource. You can use the path parameter in the URI to connect a subresource to its base resource. For instance, the resource URI path to get all employees belonging to the HR department (with id=10) will look like /departments/10/employees. To get the details of employee with id=200 in the HR department, you can use the following URI: /departments/10/employees/200. The resource path URI may contain plural nouns representing a collection of resources, followed by a singular resource identifier to return a specific resource item from the collection. This pattern can repeat in the URI, allowing you to drill down a collection for reading a specific item. For instance, the following URI represents an employee resource identified by id=200 within the HR department: /departments/hr/employees/200. Although the HTTP protocol does not place any limit on the length of the resource URI, it is recommended not to exceed 2,000 characters because of the restriction set by many popular browsers. Best practice: Avoid using actions or verbs in the URI as it refers to a resource. Using HATEOAS in response representation Hypertext as the Engine of Application State (HATEOAS) refers to the use of hypermedia links in the resource representations. This architectural style lets the clients dynamically navigate to the desired resource by traversing the hypermedia links present in the response body. There is no universally accepted single format for representing links between two resources in JSON. Hypertext Application Language The Hypertext API Language (HAL) is a promising proposal that sets the conventions for expressing hypermedia controls (such as links) with JSON or XML. Currently, this proposal is in the draft stage. It mainly describes two concepts for linking resources: Embedded resources: This concept provides a way to embed another resource within the current one. In the JSON format, you will use the _embedded attribute to indicate the embedded resource. Links: This concept provides links to associated resources. In the JSON format, you will use the _links attribute to link resources. Here is the link to this proposal: https://sp2.img.hsyaolu.com.cn/wp-shlf1314/2031/IMG13236.jpg” alt=”last_img” /> read more
