primarily to suit the requirements of the community with very little surplus for trade Dry farming This is commonly defined as crop cultivation without irrigation during a dry season typically in an area that receives at least inches cm of annual rainfall and relies on moisture retained in the soil from the rainy season Wet farming This refers to farming when water is accessible all year both from rainfall and irrigation Aquaponics This type of farming is a resilient agricultural technique that promotes health and nutrition It s a sustainable way to cultivate both fish and veggies Terrace Agriculture This is a popular agricultural method in mountain locations that involves the construction of terraces Terraces are horizontal man made areas formed on the slopes of hills and mountains for agricultural planting Shifting Agriculture This type of farming practise that protects soil fertility through plot field rotation as opposed to crop rotation Shifting agriculture involves clearing and cultivating a parcel of land for a brief period of time before abandoning it and allowing it to restore to its natural vegetation while the farmer moves on to another plot Commercial Agriculture This is a cropping system in which crops and livestock are cultivated in order to sell the goods on the market and profit Plantation Agriculture This is a type of commercial farming in which a single

海外TECH	DEV Community	Serverless Local Development	https://dev.to/serverless_inc/serverless-local-development-25fl	Serverless Local DevelopmentOriginally posted at ServerlessDeveloping Serverless applications is a very different way of building applications we ve been building for decades now We ve gotten used to having awesome local tooling for us to essentially run our entire application on our local machine Boy does this make development easier if you can just play around with the app as you build it without even requiring access to the Internet Then microservices came along and things have dramatically changed Serverless arrived to help ease that infrastructure burden that building an application consisting of many small services adds But it still means we need to figure out what the new dev workflow looks like in a Serverless microservice world So let s set some goals By the end of this post we should understand how we can reclaim to a large degree the ability we have always had to develop our applications on our local machines but still set us up for integrating our services into a larger team Oh and one small caveat With Serverless as a development methodology still in its infancy the ideas expressed here are my own opinion born out of experience building multiple Serverless projects solo and with teams There will be others with other ideas about how to accomplish the same thing It doesn t make any one right or wrong we are all still working out the best ways to accomplish our goals GoalsWhat is it we want to accomplish in this article Let s start with a list of items that we should hopefully have some answers for The ability to execute and debug code locally in a repeatable way Handling API calls to cloud vendor services locally Unit testing With that basic outline out of the way let s get stuck in… Local developmentBecause we are building microservices we need to get used to the idea that we should not expect to run the entire application on our development machines Having every service running constantly on your machine just so you can open up a web browser to “play with the application offline doesn t make much sense especially if your application is going to consist of s or even s or s of seperate services What we need to focus on then is getting each service running in some fashion locally so that we can easily execute the code we write our handlers that will eventually be our Lambda functions that execute our business logic To that end I have put together a Serverless bootstrap as I like to call it It is publicly available as a Gitlab Project and is incredibly easy to use to get started So lets get it cloned and go through some of the details git clone Getting startedOnce you have cloned the template run rm rf git to get rid of the current git folder so that it is ready for you to use for your own project You will also notice some folders src This is where we will store our handler function code as well as our unit tests and any entities classes or any other code we write templates This contains the base templates used by one of our plugins to generate new functions and tests The src functions and src test functions both already contain some example files for us to look at Lets take a quick look at the src functions exampleFunction js file As you can see this is a very simple function Its only purpose is as a way for us to see that our local development environment is configured correctly The other part of that is the test file src test functions exampleFunctionTest js It is this test file that really contains the brunt of our local development functionality What do I mean Well if we want to actually execute the code in our function we run this test On the line return wrapped run then response gt the run function contains whatever event object we want in this case nothing But it could be an API Gateway event object SNS S SQS or any other possible event object a Lambda function could receive Running code locallyBy default the example function and test are linked together so lets just execute the code in our function to see how it all works Make sure you have the mocha plugin installed globally npm install g mocha and then run the test from the root of the service mocha src test functions exampleFunctionTest jsWhat you should see are some successful results Lets make a small edit On the line return wrapped run then response gt change it to Then lets edit the function itself at src functions exampleFunction js to look like When you run mocha src test functions exampleFunctionTest js again you should now see our console log included in the response Thats it We now have local execution working You could use this very easily to setup mocha integration with your IDE of choice and even setup debugging so you can step through your code line by line inspecting variables and everything else that comes with a local debugger One step in the right direction But we don t want to have to copy and paste the contents of this test file and its handler function everytime we want to create a new function Well we don t have to Because of the awesome serverless mocha plugin that has been responsible for making our lives easier so far we can also use a CLI command that will create a function a linked test file as well as an eventless entry into our serverless yml for us The command looks something like this sls create function f functioname handler src functions fileName handlerName path src test functions stage localFor more details about this awesome plugin check out the Github page AWS Services locallyOne of the benefits of Serverless especially in the AWS ecosystem is that we have access to an incredible array of managed services that take away a large amount of the drudgery from building complex web applications However when you need to test code locally that tries to communicate to services such as S DynamoDB SNS SQS amongst others it becomes tricky There are many different ways people try to solve this problem but my favorite is a technique called mocking By making use of another NPM module aws sdk mock we can capture requests that would normally go to an AWS service and then return whatever we want We can return a successful response or we can even simulate an AWS service error if we wish to test how we manage failures To try this out lets go back to our src test functions exampleFunctionTest js file and edit the test section to look like this All that we have done here is add a mock in to catch any call to S s putObject API call when we run our tests In this case we are just responding with a success and an empty object If we had returned with a reject new Error Some error here our function would need to catch that error and deal with it just like in the real world The aws sdk mock module can do with this any SDK and API in the aws sdk module and you should go check out more details here With the combination of those two plugins alone we now have ways to run our functions locally step through them with a debugger and even simulate success and failure response from the AWS services we will more than likely be using The next step from here is to look at how we can incorporate this service we have been building in isolation into the rest of our application as a whole If you have any comments to add join us on the Serverless Forum or feel free to fork the project on Gitlab and make any merge requests to improve the bootstrap template	2022-04-04 05:05:38

海外TECH	DEV Community	Robotic Projects: Reasons for Switching from ROS2 to ROS1	https://dev.to/admantium/robotic-projects-reasons-for-switching-from-ros2-to-ros1-4ka9	Robotic Projects Reasons for Switching from ROS to ROSThe robot operating system ROS is the most widely used robotic middleware platform It s being used in the robotics community for more than years both in the hobbyist area as in industry ROS can be used on a wide array of microcontrollers and computers from Arduino to Raspberry Pi to your Linux Workstation and it offers hardware support for motor controllers visual sensors depth cameras and laser scanners In my project to build a robot I worked with both ROS and ROS So far I finished out of phases The first phase was research Understanding the hardware and software of robotic researching microcontroller and sensor testing libraries and middleware In the second phase I built an Arduino based prototype an IR controlled wheel vehicle that I termed RADU Now Phase has two distinct parts Simulate the robot with ROS then build a ROS enabled robot And this is the dilemma The simulation with ROS hard earned with long trial amp error periods could not be extended to the concrete robot because my hardware is not supported For a long time I considered this and finally decided to continue with ROS from hereon This article summarizes my experiences and explains the rationale for the final choice This article originally appeared at my blog admantium com Recapitulating my Robot ProjectWhen starting the project at the beginning of my first experience with ROS was confined to pure simulation With an Ubuntu base Linux running as a VM on my laptop I installed ROS noetic with RViz and made a simple URDF model of a four wheeled robot Then I bought a robot chassis several Arduino Uno and V compliant sensors Working through the tutorials understanding how Arduino works and how sensor data is measured and processed was an invigorating time I had many eureka moments in which after some difficulties the sensor would suddenly work This phase finished with a first concrete prototype a moving wheel chassis controlled by an IR Preparing the full utilization of ROS in my project I installed ROS on a dedicated Linux Workstation Then I began to port my simple RViz ROS model to ROS and extend the model to be compliant with Gazebo On the fun side was learning the physics behind robots and getting deep knowledge of ROS concepts On the downside I spend long periods of trial and error to develop a Gazebo compatible model But finally I could launch the simulation start a teleop node and move the robot in a simulation streaming point cloud sensor data From simulation to robot was the next phase In the meantime the Raspberry Pico entered the stage Initially I just tested how to add sensors and read them with C and MicroPython But reading several tutorials and watching videos around Raspberry Pi based projects with robot control software in Python convinced me of the feasibility Writing the motor control software from Scratch in MicroPython became my goal I rebuild my Robot completely with MicroPython and added also a ROS Twist Message to motor control commands wrapper The robot moved But when adding my Realsense D camera I could not get point cloud data streamed with ROS after several hours of trying Out of curiosity I switched to ROS and here it worked out of the box This revelation gave rise to the observations summarized in the next paragraph ROS vs ROSROS is the ROS of the future According to information from community websites and YouTube videos ROS is geared towards industrial use Robot communication uses a standard middleware layer called XRCE DDS ROS also inhibits feature of system self healing and reliability such as no ROS master node is required to run When looking into concrete robot projects ROS robots from the community pale against ROS robots Most projects developed in the last years still work with ROS I did not consider this fact merely felt astonished because ROS was already released since After working with ROS for simulating a robot and for getting ROS to run with my robot sensors particularly the RealsenseD camera several obstacles occurred to me This is a personal recollection First when searching for how to connect a certain sensor ROS related information concrete articles documentation or YouTube videos is hard to find or non existent Second documentation about special topics such as Gazebo controllers and Gazebo plugins is incomplete If you want to build a Gazebo simulation there are explorative and comprehensive manuals for ROS but for ROS you need to fetch information pieces from different websites assemble them and use a lot of trial and error before it works Getting my robots simulation to work with all sensors and topic in Gazebo RVIZ was a long journey Third when assembling a robot by using an SBC and connect it to microcontrollers you will be surprised to find out that there is no universal library for connecting them via serial as explained in this blog post You either need to use very specific microcontrollers and compile a custom RTOS Linux distribution to them making it hard to reuse your e g Arduino libraries Or you need special board with networking features Fourth checking hardware support for ROS shows that fewer options are available and the other robot enthusiasts have problems to get ROS running I had the very same experience when trying to get the Intel Real SenseD work with ROS Although I used the latest firmware compiled the librealsense from scratch compiled the ros realsense package it did just not work and even a thread on the very responsive and helpful community issue board did not find an answer When I switched to ROS the same sensor just works without any problems Generalizing these observations leads me to the sad conclusion that using ROS means to find fewer documentation have fewer support for sensors and harder integration of SBCs and microcontroller Switching to ROSThe experience in getting the gazebo Simulation to work in ROS was mostly trial and error Getting the Realsense camera to work in ROS was not successful Thereby reading from other about similar errors and problems with ROS was another impact And finally when researching about the next aspects of using ROS on my robot like SLAM autonomous movements gripper did reveal time and time again complete tutorials and books in ROS I made the decision My project will be continued with ROS	2022-04-04 05:01:27
