海外TECH	DEV Community	Watch the birds on your backyard with a Raspberry Pi, Edge Impulse and balena	https://dev.to/mpous/meet-the-birds-on-your-backyard-with-a-raspberry-pi-edge-impulse-and-balena-58hm	Watch the birds on your backyard with a Raspberry Pi Edge Impulse and balenaI love birds but to be honest with you I don t have any clue about birds My parents installed an Amazon camera in their backyard and we started to get video streams of birds going to a bird feeder that was awesome However I couldn t tell my children what type of bird was on the camera Then at the childrens school we installed a nest for birds with sensors but we couldn t get any image when a bird was detected And by serendipity the balena Ambassador Mithun Das was working on a Bird Watcher project In this post I would like to share how you can build a Bird Watcher at home Once you have it you will be able to watch birds eating on your bird feeder Plus detect with a Machine Learning model running on Edge Impulse the type of the bird Everything runs on a Raspberry Pi using balena and a camera Some of the goals of building a Bird Watcher are related to learning about birds around us plus experimenting with different materials to build the bird feeder But lately as well to introduce IoT and AI to children Cameras are not just cameras that take pictures anymore Requirements HardwareRaspberry Pi or balenaFinSD card in case of the RPi Power supply and optionally ethernet cablePi Camera or USB Camera SoftwareA balenaCloud account sign up here An Edge Impulse account clone Mithun s ML model balenaEtcherInstall Telegram on your mobile device Deploy the fleet One click deploy using Balena DeployRunning this project is as simple as deploying it to a balenaCloud application You can do it in just one click by using the button below Follow instructions click Add a Device and flash an SD card with that OS image dowloaded from balenaCloud Enjoy the magic Over The Air Join the balenaHub fleetKeep it even more simple and join the BirdWatcher fleet on balenaHub Train your machine learning model to detect birdsFirst thing needed is to have your own Birds Machine Learning model made with Edge Impulse My recommendation is to start with Mithun s ML model here Clone it on your Edge Impulse free account If you prefer to start from scratch Just create an Edge Impulse project and choose Images Then select that you would like to Classify multiple objects object detection With this you will be able to detect the location of multiple objects in an image For example to detect many birds eating at the bird feeder together Have in mind that the object detection is more compute intensive than image classification method and it s only available for Linux based devices like the Raspberry Pi or Jetson Nano Remember on this project we are going to use the Raspberry Pi running on balena Data acquisitionNow it s time to create the Training Data and the Test Data acquiring data from the sensors In our case our sensor will be a camera My recommendation is to upload pictures from birds that you know that live in your region In the future the best will be to train your model with pictures from the Bird Watcher device with your background and label them on Edge Impulse Remember to add the correct labels to all the birds From my experience to get a good Machine Learning model from pictures you will need dozens of pictures for each type of bird so be patient Impulse DesignNext step is to create the Impulse An impulse takes raw data a picture in our case and uses signal processing to extract features and then uses a learning block to classify the new data Once the impulse is saved it s time to check the raw data of the sample and Generate features When you click “Generate features you will see the feature explorer diagram with all the samples represented on a X Y Z axis This will enable you to see if the samples from the model are properly separated on the system and that means that the ML model will properly detect the birds Finally it s time to click Object detection and train your Neural Network MobileNetV Once you have fine tined the training settings number of training cycles learning rate and validation set size click Start Training As a training output you will get the last training performance with a precision score and more information about the model generated Deploy with balenaNow you are ready to deploy your device with balena Go to the BirdWatcher Github repository and click Deploy with balena If you don t have a balenaCloud account create a free account you will be able to connect up to devices for free and create a fleet The BirdWatcher project will deploy the latest release of the source code on your fleet Click Add a new device configure the balenaOS add WiFi credentials and download it or flash directly the SD card of your Raspberry Pi using balenaEtcher Introduce the flashed SD card into the Raspberry Pi and power it up You should be able to see your device on your fleet getting online and all the BirdWatcher services getting released Open your birdwatcher local websiteOnce you see the device online and ready on balenaCloud Check that your laptop mobile device is connected to the same WiFi as your Bird Watcher Type into your browser On the local UI you will be able to see the stream from the camera on the BirdWatcher Watched birdsClick on Snaps to see all the watched birds plus Birds detected that are unknown as we are using the camera of the Raspberry Pi as a motion sensor From Snaps you will be able to send pictures to Edge Impulse to retrain the ML model The picture sent to Edge Impulse is going to be a picture without any square on it SettingsGo to Settings and start defining your settings as your Edge Impulse keys On the other hand enable the motion flag if you want to watch the unknown birds record the images to feed your Edge Impulse ML model to retrain it Add Y to the ENABLE MOTION variable Finally if you would like to send the pictures and results from the ML model over Telegram turn on the telegram notifications Set the ENABLE TG to Y and add the keys of your Telegram bot Print your Bird FeederDownload STL files from here bird watcher D print zip AttributionsThank you to Mithun Das for developing this amazing application and Edge Impulse to provide support on the balena Linux integration	2022-02-14 13:44:27

海外TECH	DEV Community	Distributed storage in 30 minutes	https://dev.to/tarantool/distributed-storage-in-30-minutes-1a9f	Distributed storage in minutesAuthor Igor ZolotarevHello my name is Igor and I am a part of the Tarantool DB team When developing I often need rapid prototypes of database applications for example to test code or to create an MVP Of course I would like such a prototype to require minimal effort to refine in case it is decided to use it in production I don t like wasting my time configuring an SQL database thinking about how to manage data sharding or spending even more time studying connector interfaces I prefer just to write a few lines of code run it and have everything working out of the box To develop distributed applications rapidly I use Cartridge a framework for managing cluster applications based on Tarantool a NoSQL database Today I will show how to quickly write a Cartridge based application cover it with tests and run it The article will be of interest to anyone tired of spending a lot of time prototyping applications as well as those who want to try a new NoSQL technology ContentsFrom this article you will learn what Cartridge is and what principles to have in mind when writing cluster business logic in it We will write a cluster application for storing data about employees of a company The steps to accomplish it are Creating an application from a template with cartridge cli Describing your business logic in Lua in terms of Cartridge cluster roles Data Storage Custom HTTP API Writing tests Launching and configuring a small cluster locally Downloading configuration Configuring failover Cartridge frameworkCartridge is a framework for developing cluster applications It manages several instances of the Tarantool NoSQL database and shards data using the vshard module Tarantool is a persistent in memory database It is very fast due to storing data in RAM but also reliable since Tarantool dumps all data to the hard disk and allows you to set up replication Cartridge takes care of configuring Tarantool nodes and sharding cluster nodes which leaves a developer with only writing the business logic of the applications and configuring the failover Advantages of Cartridge Sharding and replication out of the box Built in failover support CRUD a NoSQL cluster query language Integration testing of the entire cluster Ansible based cluster management Cluster administration utility Monitoring tools Creating the first applicationTo do this we will need cartridge cli It is a utility for working with Cartridge applications It allows you to create an application from a template manage a locally running cluster and connect to Tarantool instances Installing Tarantool and cartridge cliOn Debian or Ubuntu curl L bashsudo apt install cartridge cliOn CentOS Fedora or ALT Linux curl L bashsudo yum install cartridge cliOn macOS brew install tarantoolbrew install cartridge cliLet s create a template application named myapp cartridge create name myappcd myapptree Now we get a project structure similar to this myapp├ーapp│└ーroles│└ーcustom lua├ーtest├ーinit lua├ーmyapp scm rockspec the init lua file is the entry point of the Cartridge application It defines the cluster s configuration and calls the functions required at the start of each application node the app roles directory contains roles describing the application s business logic the myapp scm rockspec file specifies the application s dependenciesBy now we already have a working Hello world application It can be started with the following commandscartridge buildcartridge start dcartridge replicasets setup bootstrap vshardAfter that access to localhost hello will show Hello world Let s now create a small template based application a sharded storage with an HTTP API for storing and receiving data To do this we need to understand how to implement cluster business logic in Cartridge Writing business logic in CartridgeEach cluster application is based on roles Lua modules describing the application s business logic For example they can be modules that store data provide HTTP API or cache data from an Oracle database A role is assigned to a set of instances joined by replication a replica set and it is enabled at each instance Replica sets can have different set of roles In Cartridge on each cluster node there is a cluster configuration It describes the cluster s topology and optionally the configuration that your role would use Such configuration can be changed in runtime to affect the role s behavior Each role has a structure similar to this return role name your role name init init validate config validate config apply config apply config stop stop rpc function rpc function dependencies another role name Role lifecycle An instance is starting The role named role name waits for the start of all its dependent roles specified in dependencies The validate config function is called to check whether the role s configuration is valid The role initialization function init is called This function performs the actions that need to be done once when the role is started for the first time The apply config function is called to apply the configuration if it is specified The validate config and apply config functions are also called whenever the role s configuration changes The role is saved in the registry From there it will be available to other roles on the same node viacartridge service get your role name The functions declared in a role will be available from other nodes viacartridge rpc call your role name rpc function Before a role is stopped or restarted the stop function is launched It terminates the role for example removing the fibers created by the role Cluster NoSQL queriesThere are several ways to write cluster queries in Cartridge Calling functions via the vshard API this is a complicated but flexible way vshard router callrw bucket id app roles myrole my rpc func Tarantool CRUD Simple function calls crud insert get replace Support for calculating bucket id is limited Roles must depend on crud router crud storage Application structureSuppose we want a cluster with one router and two groups of storages with two instances each This topology is typical for both Redis Cluster and MongoDB Cluster For the stateful failover to save the state of the current masters the cluster will include stateboard yet another instance When increased reliability is required it is better to use an etcd cluster instead of stateboard The router will distribute requests across the cluster and manage the failover Writing custom rolesWe will need to write two roles one for data storage and one for HTTP API In the app roles directory we create two new files app roles storage lua and app roles api lua Data StorageLet s describe the role for data storage In the init function we will create a table and indexes for it then add crud storage to its dependencies The Lua code in the init function is equivalent to the following pseudo SQL code CREATE TABLE employee bucket id unsigned employee id string name string department string position string salary unsigned CREATE UNIQUE INDEX primary ON employee employee id CREATE INDEX bucket id ON employee bucket id Add the following code to the app roles storage lua file local function init opts opts has the attribute indicating if the function is called at the master or at the replica we create tables only at the master instance they will appear automatically at the replica if opts is master then Creating a table with employees local employee box schema space create employee if not exists true setting the format employee format name bucket id type unsigned name employee id type string comment ID сотрудника name name type string comment Р¤Р˜РћСЃРѕС‚СЂСѓРґРЅРёРєР° name department type string comment Отдел name position type string comment Ролжность name salary type unsigned comment Рーарплата Create the primary index employee create index primary parts field employee id if not exists true Indexing by bucket id it is necessary for sharding employee create index bucket id parts field bucket id unique false if not exists true end return trueendreturn init init lt lt lt remembering the crud storage dependency dependencies cartridge roles crud storage We will not need the rest of the functions from the role s API since our role has no configuration and it does not allocate resources to be cleaned after the role s work is complete HTTP APIWe will need the second role to fill the tables with data and retrieve this data on request The role will access the Cartridge s built in HTTP server It depends on crud router Let s define a function to handle POST requests The request body will contain the object to be saved to the database local function post employee request getting an object from the request body local employee request json writing it to the database local err crud insert object employee employee if an error occurs writing it to the log and returning if err nil then log error err return status end return status endThe GET method will take the employees salary values as a parameter The expected response is a JSON with a list of employees whose salary is higher than the one specified in the request SELECT employee id name department position salaryFROM employeeWHERE salary gt salarylocal function get employees by salary request get the salary parameter from the query local salary tonumber request query param salary or selecting the employee data local employees err crud select employee gt salary

the unflatten rows function converts a table row to a key value table employees crud unflatten rows employees rows employees metadata employees fun iter employees map function x return employee id x employee id name x name department x department position x position salary x salary end totable return request render json employees endNow let s write the init function for the role Here we will turn to the Cartridge s registry to get an HTTP server and use it to assign the HTTP endpoints for the application local function init getting an HTTP server from the Cartridge s registry local httpd

defaultTo see the parameters of the configured instances take a look at the instances yml file Running the cluster locally cartridge buildcartridge start dcartridge replicasets setup bootstrap vshardNow we can enter WebUI to load the roles configuration and to configure the failover To configure a stateful failover do the following click the Failover button choose stateful specify the address and the password localhost passwdLet s see how it works Now the leader in the s replica set is s master Let s stop it cartridge stop s masterNow s replica becomes the leader Let s restore s master cartridge start d s masters master is up again but s replica is still the leader because of the stateful failover Let s load the configuration for the cartridge roles metrics role To do this switch to the Code tab and create the metrics yml file with the following contents export path metrics format prometheus path health format healthAfter we click the Apply button the metrics will become available at each node of the application at the localhost metrics endpoint The health check page at the localhost health address will also appear This completes the basic setup of a small application the cluster is ready to run and now we can write an application to communicate with the cluster using the HTTP API or via a connector We can also expand the functionality of the cluster ConclusionMany developers hate wasting time configuring a database We prefer simply writing code and leaving cluster management to a framework To solve this problem I use Cartridge a framework that manages a cluster containing several instances of a Tarantool database Now you know how to build a reliable cluster application based on Cartridge and Tarantool how to write the code for a small application to store information about employees how to add tests how to configure a cluster I hope my story was helpful and you will start using Cartridge to create applications I would be glad to hear feedback on whether you managed to write a Cartridge application quickly and easily as well as questions about its use What s next Check out the documentation on the official website Try
