camera coordinate right handed with z pointing away from the camera towards the view direction and y axis pointing down note that the opencv convention camtools default is different from the opengl blender convention where z points towards the opposite view direction and the y axis points up to convert between the opencv camera coordinates and the opengl style coordinates use the conversion functions such as ct convert t opencv to opengl ct convert t opengl to opencv ct convert pose opencv to opengl and ct convert pose opengl to opencv etc image coordinate starts from the top left corner of the image with x pointing right corresponding to the image width and y pointing down corresponding to the image height this is consistent with opencv pay attention that the 0th dimension in the image array is the height i e y and the 1st dimension is the width i e x that is x u width column the 1st dimension y v height row the 0th dimension k 3 3 camera intrinsic matrix python k fx s cx 0 fy

concepts verified telemetry concepts verified telemetry device sample verified telemetry device sample verified telemetry overview verified telemetry vt is a state of the art solution to determine the health of the sensor i e working or faulty which is consequently used to determine the quality of the sensed data this is achieved by devising an intelligent sensor fingerprint a set of unique electrical characteristics that differs between working and faulty sensors the fingerprints can detect faults for a wide variety of off the shelf sensors and can be easily implemented with lightweight software code running on the iot device vt code is split into three repositories as described below description verified telemetry sdk https github com azure verified telemetry the sdk which builds on

telemetry now support both analog and digital sensors refer to the sensor configuration guide demos sample azure iot pnp to configure your sample according to the sensors used verified telemetry concepts a few key concepts of vt are introduced and discussed below 1 sensor fingerprint sensor fingerprint is an electrical characteristic that is measured by the iot device for a particular sensor the sensor fingerprint of a working sensor differs from that of a sensor with fault 1 sensor fingerprint template sensor fingerprint template is a fingerprint of a working sensor the fingerprint template is collected by the iot device ideally when the sensor is provisioned first and stored locally and in the digital twin 1 sensor fingerprint collection sensor fingerprint collection is a process where the iot device measures the fingerprint of a sensor in the device samples sensor fingerprint is collected at the same frequency at which telemetry is sent by the iot device 1 sensor fingerprint evaluation a sensor fingerprint that is collected is then compared with the stored sensor fingerprint template if the collected fingerprint matches with the sensor fingerprint template the sensor is classified as working otherwise faulty 1 telemetry status the telemetry status of the telemetry that is generated by the sensor is tagged true if the sensor is working and false if the sensor has a fault the telemetry status for each telemetry that supports verified telemetry feature exists as a non writable property in the digital twin 1 fingerprint template synchronization at boot if the sensor fingerprint template exists in the digital twin it is fetched and updated on the device when the device boots resets this ensures fingerprint template is collected only once when device is provisioned if the sensor fingerprint template does not exist in the digital twin the template on device remains empty after boot and subsequent sensor fingerprint evaluation cannot be performed 1

user s device when the user selects a photo within our app then our app turns the photo into a slide puzzle and shuffles it example 2 given the user s device has a functioning camera when the user takes a photo through our app then our app turns the photo into a slide puzzle and shuffles it example 3 given the user can select or take a photo through our app when the user cancels the photo selection then no slide puzzle will be generated requirement 2 as a user i want to be able generate a random slide puzzle from an image the app chooses example 1 given the user s device is connected to wifi when the user chooses to generate a random puzzle then our app downloads a picture from an online database generates a slide puzzle and shuffles it example 2 given the user s device is connected to cellular data but not wifi when the user chooses to generate a random puzzle then our app warns the user of potential cellular data usage and waits for confirmation or cancellation example 3 given the user s device has no internet connection when the user chooses to generate a random puzzle then our app alerts the user of the lack of internet connectivity and offers to generate a puzzle from the device s local photos requirement 3 as a user i want to be able to save puzzles to solve again at another time example 1 given the user has signed into our app when the user chooses to save a puzzle then our app saves the puzzle in its current state to a database tied to the user s account example 2 given the user has not signed into our app when the user chooses to save a puzzle then our app prompts the user to create an account or sign in to an existing account example 3 given the user is signed in and has puzzle s already saved when the user chooses to recall a previously saved puzzle then the puzzle is loaded from the database example 4 given the user is signed in and has no puzzles saved when the user chooses to recall a previously saved puzzle then our app alerts the user that they have no saved puzzles and does not load anything from the database example 5 given the user is not signed in when the user chooses to recall a previously saved puzzle then our app prompts the user to create an account or sign in to an existing account requirement 4 as a user i want to be able to reshuffle a slide puzzle whether or not it has been solved example 1 given a slide puzzle is being generated when our app shuffles the puzzle then our app verifies that the puzzle can be solved this can be done by the shuffling function or by a separate verification function example 2 given the user has a puzzle already generated and has not solved it when the user chooses to shuffle the puzzle then our app shuffles the puzzle tiles again example 3 given the user has a puzzle already generated and has solved it when the user chooses to shuffle the puzzle then our app alerts the user that the puzzle is solved and waits for confirmation or cancellation example 4 given the user has a puzzle already generated and the user s device has an accelerometer when the user shakes their device then our app asks if the user wanted to shuffle the puzzle and waits for confirmation or cancellation before shuffling according to examples 2 and 3 class diagram puzzlepicmvvm2 https user images githubusercontent com 81546348 120084645 d45b0500 c09f 11eb 90d1 3d7a351edf31 jpg class

performance guide a has a more detailed account of the ways in which ffcv can adapt to different performance bottlenecks plug and play with any existing training code rather than changing aspects of model training itself ffcv focuses on removing data bottlenecks which turn out to be a problem everywhere from neural network training to linear regression this means that ffcv can be introduced into any existing training code in just a few lines of code e g just swapping out the data loader and optionally the augmentation pipeline you don t have to change the model itself to make it faster e g feel free to analyze models without cutmix dropout momentum scheduling etc ffcv can speed up a lot more beyond just neural network training in fact the more data bottlenecked the application e g linear regression bulk inference etc the faster ffcv will make it see our getting started https docs ffcv io basics html guide example walkthroughs https docs ffcv io examples html and code examples https github com libffcv ffcv tree main examples to see how easy it is to get started fast data processing without the pain ffcv automatically handles data reading pre fetching caching and transfer between devices in an extremely efficiently way so that users don t have to think about it automatically fused and compiled data processing by either using pre written https docs ffcv io api transforms html ffcv transformations or easily writing custom ones https docs ffcv io ffcv examples custom transforms html users can take advantage of ffcv s compilation and pipelining abilities which will automatically fuse and compile simple python augmentations to machine code using numba https numba pydata org and schedule them asynchronously to avoid loading delays load data fast from ram ssd or networked disk ffcv exposes user friendly options that can be adjusted based on the resources available for example if a dataset fits into memory ffcv can cache it at the os level and ensure that multiple concurrent processes all get fast data access otherwise ffcv can use fast process level caching and will optimize data loading to minimize the underlying number of disk reads see the bottleneck doctor https docs ffcv io bottleneck doctor html guide for more information training multiple models per gpu thanks to fully asynchronous thread based data loading you can now interleave training multiple models on the same gpu efficiently without any data loading overhead see this guide https docs ffcv io parameter tuning html for more info dedicated tools for image handling all the features above work are equally applicable to all sorts of machine learning models but ffcv also offers some vision specific features such as fast jpeg encoding and decoding storing datasets as mixtures of raw and compressed images to trade off i o overhead and compute overhead etc see the working with images https docs ffcv io working with images html guide for more information contributors

Angela-Yu-Web-Bootcamp-2020 | about this repository contents this repository tracks my progress in march 2020 through the beginning of june 2020 completing instructional videos and programming challenges for the complete 2020 web development bootcamp available on udemy com https www udemy com course the complete web development bootcamp each week i watched the videos in the course usually at 2x speed while running on a treadmill at my local gym then later completed the programming exercises in each section about halfway through the course i started the actual programming you ll see the commit logs tracking my progress the sections directory contains brief notes i took as i watched the videos the projects directory containst the actual programming exercises in some cases the exercises were completed using cloud based tools like codepen or codesandbox wherever possible i exported those code exercises to my repository to show my work about my progress at the beginning of the course i had many years of experience in html css and javascript programming i am deeply familiar with many server side programming languages such as ruby php and to a lesser extent python however es6 css3 and modern front end frameworks such as bootstrap were very new it turns out my original schedule to complete the course in 5 weeks was too aggressive watching videos nearly every day but doing the programming only 2 3 hours per week the course took about 3 months to complete this schedule was created for myself with many years of programming experience and my nephew who had only limited html and css experience prior to starting the course original schedule angela yu webdev bootcamp schedule png i had no previous experience to any kind of server side javascript development like nodejs or express i found that i much prefer development in these environments compared to frameworks like ruby on rails where there s a little too much magic behind the scenes being done by generators and perhaps too much convention over configuration i like the balance that codes with nodejs where you can easily see your routes and template files of course nodejs and express owe a lot to ruby on rails and i brought forth some of my knowledge there early into this course you ll note that i built a singleton library to handle most of the mongodb which forced me to better understand the asynchronous nature of using callbacks in my nodejs code this slowed my progress but i feel like i achieved more course information on udemy angela yu and her group at the london app brewery did a fantastic job building this course this web development 2020 boot camp is only one of many courses from angela i have watched over the last couple of years i strongly recommend you check out all of her courses from ios and swift mobile app development to her newer courses in data science she has developed a format for beginners that is very engaging encouraging and progressive https www udemy com course ios 13 app development bootcamp https www udemy com course flutter bootcamp with dart capstone my final project not officially a part of the course is an effort to combine the secrets project which uses nodejs express and mongodb as a backend and keeper which uses reactjs as a front end i ve successfully deployed both apps separately to heroku using a mongodb atlas backend for access on the cloud i also used the dotenv package to make it easy to run both apps locally on my development laptops which includes both a 2010 model unibody macbook running macos high sierra as well as a more modern and powerful macbook pro running macos catalina it s not clear if i ll actually complete this capstone exploring several blog posts on the subject there are a few additional frameworks i should learn that would make this a lot easier i ve just started london app brewery s complete 2020 data science and machine learning bootcamp so this capstone project may end up taking the back burner for a few months https www udemy com course python data science machine learning bootcamp | front_end |

barebones-react-typescript-express | barebones react sass express typescript boilerplate nbsp table of contents purpose purpose running the project running the project server server client client styling the app styling the app configuration files ef b8 8f configuration files webpack config ef b8 8f webpack config closing remarks closing remarks nbsp purpose this project is a starting point for a typescript based react app that also has a local api server using express it serves as an excellent sandbox for learning the workflow of a full stack web application from our bootcamp there is no connection to any kind of database but our videos and course cover mysql and its integration into node and express keep in mind there isn t much quality of life in this boilerplate code you ll miss your hot reloading feature of create react app the ability to import pictures as modules and all the other fun stuff the big frameworks have already coded for you they re all still accessible but you d have to learn to add them yourself feel free to ping me cool hand luke in our discord channel if you re a student and are interested in a particular feature you d like to see a tutorial on nbsp running the project if you already know the process of cloning a repository then follow the normal process and use the script npm run dev to get up and going if you re new or are interested in the steps and their purpose then let s dive on in nbsp first bash git clone https github com covalence io barebones react typescript express git your project name this command will clone this project s code to our computers it will default to the name of the github repository but you can rename it by providing an additional argument like your project name in the above example it will create a folder by that name and copy all the juicy code into it for you nbsp second bash cd your project name hopefully this one is fairly straightforward by this point it will change directories into the folder we just cloned the code into note there are some cool shorthands you could do to combine some of these steps or making a function alias to streamline it nbsp third bash npm install this is also hopefully straightforward by now it will look into the package json and package lock json to install the needed dependencies for this project to do its job it will create your node modules folder for you which is what makes time travel possible lets the project run note that sometimes you ll see security vulnerabilities these will come and go and thankfully are easy to fix npm audit fix can do so by updating an out of date package to a new version however alot of these free packages are written in the spare time of other developers and you re at the mercy of waiting for them to fix the vulnerability nbsp fourth bash npm run dev this command will start the project for us it will sometimes take a bit depending on the speed of the computer anywhere from 10 to 20 seconds feels average don t stress if your old junker of a laptop takes longer as long as it completes without error you re good to go this script will utilize nodemon to auto restart your express server meaning any server side code you write and save will trigger a recompile rebundle and re run of the server no need to stop and restart it over and over again notice in the package json that dev runs npm run all parallel watch as the actual command it s what fires up 1 webpack to compile and bundle our code and 2 run nodemon when the server finishes building the npm run all lets us run run multiple npm scripts in parallel or sequentialy parallel means we run two npm scripts at the same time watch references any other script starting with watch check out the two in our package json they are watch build and watch server another indent level sheesh but let s break down the purpose of those watch scripts watch build will tell webpack to compile and bundle our src client folder as all of our react app and output it to public js app js it will also follow the same process for src server and output it to dist server js watch server watches the dist server js for changes and that s how it auto restarts the server unfortunately you ll have to refresh your browser to see any react app changes nbsp the server will start on port 3000 http localhost 3000 and should default to a hello world app nbsp optionally bash npm run start we will use this script in production we don t need all the auto restart stuff from the watch scripts we discussed up above just start the server and be done with it this assumes you have a dist server js and public js app js already built nbsp server the server build process compiles the typescript files found in src server into a single bundled javascript file server js located in the dist directory which is created for us during the process this will be where we code all things relating to our database whether sql or nosql it s where we ll include all of our rest api routes all of our back end utilities while there are tricks to share its code we will not be sharing any code from our src server folder into src client if you find yourself wanting to import anything directly to your client code from your server code stop and rethink how you re trying to solve this problem for all intents and purposes back end and front end are entirely separate realms of existence nbsp client the client build process compiles the typescript files found in src client into a single bundled javascript file app js located in the public js directory which is created for us during the process this will be where we code all things related to our react app and what a user will see and interact with in the browser that s it if it needs to ask for any information on the back end you will 99 of the time do so via a fetch request that hits one of your rest api endpoints nbsp styling the app the src client configuration will also build the sass files found at src client scss directory the index tsx imports the app scss file which already includes an import for bootstrap v4 notice how the bootstrap import in the src client scss app scss file is at the bottom of the file this is because our expected overrides are expected above that import think of it as here s my custom bootstrap injections and now load bootstrap with my changes mwahaha thankfully you can write normal css just as you like add class selectors element selecotrs and id selectors to your hearts content there are however several sass tricks you can research on google stack overflow youtube and etc covalence thanks to matt landers has two entry level videos discussing sass and its advantages over regular css let s get sassy https youtu be s9mku a0npo which is an intro to sass as a concept its advantages over regular css how to add it to a project remember you don t need to do that here and some tricks to using it overriding bootstrap variables https youtu be qp3fg31cdmg which goes over the basics of overriding bootstrap variables you ll notice this boilerplate already provides a basic example of that sass first override some or all individual color variables primary 25408f secondary 8f5325 success 3e8d63 info 13101c warning 945707 danger d62518 light f8f9fa dark 343a40 then add them to your custom theme colors map together with any additional colors you might need theme colors primary primary secondary secondary success success info info warning warning danger danger light light dark dark add any additional color below this takes the all bootstrap variables anywhere you use it and replaces it with a new color code add bg primary text primary and border primary to some elements in your tsx and notice how the regular deep blue bootstrap color is now replaced by our custom one you can override all the color specific keywords using this to add your own custom feel to your react bootstrap app nbsp configuration files gitignore is what we use to not push certain files or folders to github this starts with our dependencies and production bundles being ignored feel free to add any file that contains sensitive information away from github using this a common addition would be a env file for example that contains our 3rd party api keys package lock json is automatically generated whenever you run a command that modifies node modules or package json it describes the exact modification that was made such that subsequent installs like you cloning this boilerplate and installing modules are able to generate identical modifications regardless of intermediate dependency updates package json you ve seen this one a lot it s the basic metadata relevant to the project and it is used for managing the project s dependencies scripts version and a whole lot more readme md the markdown file that displays here in github that you re reading right now and what i probably use as my lecture notes during my videos tsconfig client json the typescript rules our tsc compiler will follow and allow when building our react app there are several options to play with to standarize import statements allow the use of any don t do this though lol but make sure not to remove jsx react by mistake or it won t know what you re trying to write in those tsx files tsconfig server json the same as above basically except for our server code we tell it to include the types for node and express so it can help us write the basics of our server with improved intellisense support and less manual strong typing basically it makes our tsc infer some of the basic server types for us automatically webpack config js the rules loaders and plugins our entire build process follows there s a lot of stuff bundled in this one so let s break down the high points in its own subsection below nbsp webpack config when i was but a young dev student i once attended a local meetup about react when it was still fairly new the speaker was a very experienced dev who was leading our lunch and learn discussion my favorite quote he lead with is forever forged into my memories i spent the last week trying to learn more about webpack so i can talk about it up here today and teach you all i feel like i know less than when i started that sums up my own thoughts better than my own words could that being said here s what you re staring at and we re gonna literally go top down on this sucker nbsp js const nodeexternals require webpack node externals when bundling with webpack for the backend you usually don t want to bundle its node modules dependencies this library creates an externals function that ignores node modules when bundling in webpack so this is used as a plugin in the config here externals nodeexternals in the serverconfig object basically it s making sure we re not trying to build external stuff by accident that doesn t need to be nbsp js const serverconfig this is the object we create for the compile and bundle process for our src server code nbsp js mode process env node env development this tells webpack whether it s in development or some other mode typically production are we goofing around on our local machines tinkering with a new feature and we want verbose error messages that trace back in source code where the problem occured or are we debugging a problem after we deploy our site and wonder why it crashed after we let our friend touch it webpack will have different types of outputs depending on this note that it defaults to development unless we set node env as an environment variable to production this is typically set for us on heroku by default nbsp js module resolve output target node don t stress about the guts of these properties just focus on their general purpose module lets us specify what to do with certain file extensions if webpack encounters a ts extension we provide rules loaders and options for it to do certain tasks when building them resolve this deals with how modules are resolved as in if we write import lodash in es2015 the resolve options can change where webpack goes to look for lodash for us you probably won t mess with this much output is where we output our bundle to which is dist server js target because javascript can be written for both server and browser webpack offers multiple deployment targets that you can set in your configuration this is the server object so we make sure to tell webpack we re using server javascript code nbsp js const clientconfig this is the object we create for the compile and bundle process for our src client code nbsp js mode process env node env development this tells webpack whether it s in development or some other mode typically production are we goofing around on our local machines tinkering with a new feature and we want verbose error messages that trace back in source code where the problem occured or are we debugging a problem after we deploy our site and wonder why it crashed after we let our friend touch it webpack will have different types of outputs depending on this note that it defaults to development unless we set node env as an environment variable to production this is typically set for us on heroku by default nbsp js devtool inline source map this attempts to help you when developing your react app remember we re going through several layers before running our code in the browser typescript react down to javascript react down to javascript dom using react createelement and into the browser that s a bunch of steps in between what you write and what you see running this attempts to map back to your original source code what error or what is running the browser nbsp js module resolve output don t stress about the guts of these properties just focus on their general purpose module lets us specify what to do with certain file extensions if webpack encounters a ts extension we provide rules loaders and options for it to do certain tasks when building them resolve this deals with how modules are resolved as in if we write import lodash in es2015 the resolve options can change where webpack goes to look for lodash for us you probably won t mess with this much output is where we output our bundle to which is public js app js nbsp closing remarks there are a lot of moving parts even in this barebones boilerplate this is why we provide it to you the student as a jumping off point we want you to focus on coding your server code and react code not mess with configuration files and project setup keep in mind this is not the be all end all boilerplate you can learn what features you miss from things like nextjs gatsbyjs and create react app and figure out how to add them to this one to make it your go to starter code code and code build shit and deploy get projects up and running conceptually finished and no matter how dumb you will always learn something new challenge yourself to use different css kits and libraries try other database connectors try react libraries like redux even if you aren t getting paid for it it s still valuable experience for you so happy hacking and have some fun | front_end |

dataset we passed to the model output features pushing the prediction higher are shown in red those pushing the prediction lower are in blue another way to visualize the same explanation is to use a

for an entire dataset in the notebook this plot is interactive python visualize all the training set predictions shap plots force shap values 500 p align center img width 811 src docs artwork california dataset png p to understand how a single feature effects the output of the model we can plot the shap value of that feature vs the value of the feature for all the examples in a dataset since shap values represent a feature s responsibility for a change in the model output the plot below represents the change in predicted house price as the latitude changes vertical dispersion at a single value of latitude represents interaction effects with other features to help reveal these interactions we can color by another feature if we pass the whole explanation tensor to the color argument the scatter plot will pick the best feature to color by in this case it picks longitude python create a dependence scatter plot to show the effect of a single feature across the whole dataset shap plots scatter shap values latitude color shap values p align center img width 544 src docs artwork california scatter png p to get an overview of which features are most important for a model we can plot the shap values of every feature for every sample the plot below sorts features by the sum of shap value magnitudes over all samples and uses shap values to show the distribution of the impacts each feature has on the model output the color represents the feature value red high blue low this reveals for example that higher median incomes improves the predicted home price python summarize the effects of all the features shap plots beeswarm shap values p align center img width 583 src docs artwork california beeswarm png p we can also just take the mean absolute value of the

high speed approximation algorithm for shap values in deep learning models that builds on a connection with deeplift https arxiv org abs 1704 02685 described in the shap nips paper the implementation here differs from the original deeplift by using a distribution of background samples instead of a single reference value and using shapley equations to linearize components such as max softmax products divisions etc note that some of these enhancements have also been since integrated into deeplift tensorflow models and keras models using the tensorflow backend are supported there is also preliminary support for pytorch python include code from https github com keras team keras blob master examples mnist cnn py import shap import numpy as np select a set of background examples to take

gradients https arxiv org abs 1703 01365 shap and smoothgrad https arxiv org abs 1706 03825 into a single expected value equation this allows an entire dataset to be used as the background distribution as opposed to a single reference value and allows local smoothing if we approximate the model with a linear function between each background data sample and the current input to be explained and we assume the input features are independent then expected gradients will compute approximate shap values in the example below we have explained how the 7th intermediate layer of the

was teaching him the basics of computer programming making a simple text based rock paper scissors game in python at that time i was starting to experiment with computer vision with a raspberry pi and an old usb webcam so my son naively asked me could you make a rock paper scissors game that uses the camera to detect hand gestures i accepted the challenge and about a year and a lot of learning later i completed the challenge with a functional game overview of the game the game uses a raspberry pi computer and raspberry pi camera installed on a 3d printed support with led strips to achieve consistent images the pictures taken by the camera are processed and fed to an image classifier that determines whether the gesture corresponds to rock paper or scissors gestures the image classifier uses a support vector machine https en wikipedia org wiki support vector machine a class of machine learning https en wikipedia org wiki machine learning algorithm the image classifier has been priorly trained with a bank of labeled images corresponding to the rock paper scissors gestures captured with the raspberry pi camera how it works the image below shows the processing pipeline for the training of the image classifier top portion and the prediction of gesture for new images captured by the camera during the game bottom portion click here https raw githubusercontent com drgfreeman

services iot hub wt mc id iot 0000 pdecarlo service which enables us to securely connect monitor and manage iot devices if you have already deployed any of these services into an existing environment you are welcome to reuse them in the lab however it is highly suggested to create brand new services to avoid issues deploy the required services by clicking deploy to azure button below deploy to azure http azuredeploy net deploybutton png https portal azure com create microsoft template uri https 3a 2f 2fraw githubusercontent com 2ftoolboc 2fiotedge devops 2fmaster 2fazuredeploy json on the resulting screen supply a globally unique value for the resource name suffix parameter deploy to azure content deploytoazure png if you encounter any issues in the deployment it is advised to delete the created resource group if any and retry with a new value for the resource name suffix parameter step 2 setup azure devops services azure devops services allows for building testing and deploying code in an easy to manage interface we will build out a base for iot edge devops practices using services provided by azure devops services if you have not already create a new azure devops services account here https azure microsoft com services devops wt mc id iot 0000 pdecarlo next create a new project and give it a descriptive name create project content createprojectvsts png next select repos then click the import button underneath import a repository and supply this url https github com toolboc iotedge devops git import gh to azure devops content importghtovsts png the import process should begin importing this repository into your azure devops project step 3 setting up continuous integration this repository contains an azure devops build definition which is preconfigured to build the included edgesolution in azure pipelines yml azure pipelines yml this build definition relies on an external plugin replace tokens https marketplace visualstudio com items itemname qetza replacetokens wt mc id iot 0000 pdecarlo begin by installing the replace tokens task from the visual studio marketplace by visiting this link https marketplace visualstudio com items itemname qetza replacetokens wt mc id iot 0000 pdecarlo and clicking the get it free button then install into the organization which contains your newly created azure devops project once this task is successfully installed return to the azure devops project and select repos files then edit the azure pipelines yml file edit build definition content editbuilddefvsts png add the following comment to the top of the file as shown below this repository is built using azure devops commit the changes as shown commit build definition content commitbuilddefvsts png navigate back to repos and select set up build then select run and you should see that a build has kicked off upon editing the build definition created build definition content builddefcreated png the build will fail this is to be expected as we need to add a few build variables in order for the build to run successfully we will need to obtain the hostname of the azure container registry which will be represented by acr host in addition we will need the azure container registry username which will be represented by acr user and finally the azure container registry password which will be represented by acr password all of these can be obtained in the azure portal by viewing your created azure container registry and selecting access keys as shown below azure container registry content acr png next we need to obtain the application insights instrumentation key which will be represented by appinsights instrumentationkey this can be obtained in the azure portal by viewing your created application insight resource as shown below application insights content appinsights png once you have obtained all of the necessary values create a build definition variable for acr host acr user acr password and appinsights instrumentationkey as shown below edit build definition variables content editbuilddefvars png build definition variables content builddefvars png finally select the run button and click run in the dialogue as shown below queue build definition content queuebuildvsts png the build should complete successfully as shown below queue build definition content buildsuccessvsts png with a successful build definition in place we can now enforce continuous integration by applying a branch policy to the master branch start by selecting repos branches then click the on the row for the master branch and select branch policies select branch policy content selectbranchpolicyvsts png next under build validation click add build policy and select the newly created build pipeline then click the save button configure build policy content buildpolicyvsts png while this policy is enabled all commits to feature branches will kick off an execution of the newly created build pipeline and it must succeed in order for a pull request of those changes to be made to the master branch step 4 creating a release pipeline with a smoke test deployments to devices need to be done under tight control in production environments to achieve this we will create a release pipeline which deploys to qa devices and smoke tests the edge runtime in a containerized device this is accomplished by running an instance of the azure iot edge device container https github com toolboc azure iot edge device container which is configured as a qa device then probing the iot hub to ensure that qa device receives the desired deployment configuration and is able to successfully run all configured modules this test is contained in edgesmoketest sh scripts edgesmoketest sh to begin select pipelines releases then create a new pipeline with an empty job and save it create empty job content emptyjobvsts png now head back to build and release releases new and select import a pipeline import a pipeline content importapipelinevsts png download the release pipeline json release pipeline json file located in the root of this repo and import it the initial pipeline content initialpipelinevsts png there are a few things that we will need to fix before we can successfully run the release pipeline specifically azure subscription endpoints agent pools and variable settings and artifact source to fix the azure subscription endpoints select tasks create deployment and supply the appropriate azure subscription and azure container registry for the azure iot edge push module images and azure iot edge deploy to iot edge devices tasks fix endpoints 1 content fixazureendpoints1 png fix endpoints 2 content fixazureendpoints2 png next select tasks smoke test and supply the appropriate azure subscription and azure container registry for the remove all registered qa devices and smoke test tasks fix endpoints 3 content fixazureendpoints3 png fix endpoints 4 content fixazureendpoints4 png to fix the agent pools select tasks create deployment agent job and change the agent pool to azure pipelines and set agent specification to ubuntu 18 04 fix agent pool 1 content agentpool1 png fix agent pool 2 content agentpool2 png with these fixes applied you should be able to save the release pipeline it is highly recommended to save at this point if azure devops allows to fix the variables select variables pipeline variables content pipelinevarsvsts png we will need to modify all variables in brackets you may use the same values for acr host acr user acr password and appinsights instrumentationkey that were used in the ci build definition in step 3 iothub name is the name of the iot hub that was created in step 1 for the additional variables we need to create a service principal by performing the following install the azure cli https docs microsoft com cli azure install azure cli view azure cli latest wt mc id iot 0000 pdecarlo run az login to sign in with the azure cli then run az account list to see available subscriptions and set the appropriate subscription with az account set subscription subscriptionid create a service principal for your subscription with the azure cli it is suggested to use a value of iotedge devops or similar for name az ad sp create for rbac name name you should see output similar to appid 12345678 1234 1234 1234 1234567890ab displayname iotedge devops name http iotedge devops password mypassword tenant abcdefgh abcd abcd abcd abcdefghijkl take note of the name password and tenant as these values will be used for spappurl sppassword and tenant respectively note that some passwords could be generated with characters that can cause issues when interpreted from the linux command line if this is the case for example if the resulting password contains a then you can either regenerate a new password by re running the command above or you could try to wrap this value with single quotes i e password any failures that may arise in the smoke test are usually attributed to these values obtain the following parameters and supply the appropriate values for the remaining release pipeline variables parameter description spappurl the service principal app url required sppassword the password for the service principal required tenantid the tenant id for the service principal required subscriptionid the azure subscription id where the iot hub is deployed required to test these parameters on a local docker on linux instance to rule out any potential issues you can use the following command docker run d e spappurl spappurl e sppassword sppassword e tenantid tenantid e subscriptionid subscriptionid e iothub name iothub name e environment qa name qa test restart no v var run docker sock var run docker sock toolboc azure iot edge device container if the container fails to start there is likely an issue with the parameters provided if these fail locally they will also likely fail in the release build once you have properly set the variables for the release we need to fix the artifact source select pipeline add an artifact add new artifact content addnewartifact png next select your ci build pipeline as source and configure to obtain the latest version add new artifact content addnewartifact2 png once you have configured everything appropriately select save then pipelines releases then select the newly created release pipeline and create a release create a release content createreleasevsts png the new release pipeline should begin running running release content runningreleasevsts png step 5 monitoring devices with app insights monitoring allows us to perform long running tests against edge modules and provide real time alerts using application insights our edgesolution includes a dockerappinsights module which is configured in deployment template json edgesolution deployment template json this module monitors the docker host of each containerized iot edge device assuming a device has been deployed and is running you can monitor the device by viewing the appication insights resource deployed in step 1 app insights graph content appinsightsgraph png to configure a chart select metrics explorer add chart edit chart and add the following to monitor block io for all edge modules app insights block io content aiblkio png add the following to monitor the network traffic for all edge modules app insights block io content

analysis why i was just building a small fuzzy finder to get urls from blog content to easily access content while i m learning about timescale i d like to have a fuzzy finder to easy find posts https blog timescale com or docs https docs timescale com from timescale validating if all internal links are working and so on then i thought 1 i m getting more deep on technical writing and my objective is better understand the industry language and the jargons i d like to play with this data and have fun with statistics related to text writing 2 i m also very interested in data science and i d like to explore all the data in different ways 3 i m benchmarking the smallest instance that forge https www timescale com forge can offer wink installation it s not a rubygem yet so you need to clone and

ghg-emissions | greenhouse gas emissions data comparison this is an end to end data engineering and analytical project which aims to provide comparison of two different sources with greenhouse gas emissions data and visualize the greenhouse gas contributions of different sectors and agrifood systems in particular disclaimer in order to focus on the data engineering and analytical tasks i disregard some technical details about the datasets and make some intentional assumptions about them that might not be correct please use the results with caution overview the whole project was built using google cloud platform services and dbt schema of services integration assets services schema png schema of services integration schema of services integration data sources climate watch data accessed using api call with optional parameters from the https www climatewatchdata org api v1 data historical emissions https www climatewatchdata org api v1 data historical emissions url address faostat data had to be downloaded manually from the https www fao org faostat en data gt https www fao org faostat en data gt url address data ingestion data were ingested using google cloud function etl scripts written in python transformed data was stored in google bigquery data warehouse in a dataset called ghg the scripts allow for incremental data refresh if the source data either requeted via api call or downloaded from the faostat website was already in target tables it got updated no data is deleted in this process the transformation scripts were slightly different for each data source climate watch cw data load scripts cw data load data fetched in the script and pushed to cw data stg table afterwards data was merged with target table cw data faostat fao data load scripts fao data load the data was uploaded to a google cloud storage bucket that triggered the etl script the etl script transformed and enriched the data finally the data was uploaded to fao data stg table and merged with fao data table additional dimension tables were added to the ghg dataset tables of the ghg dataset assets bigquery ghg png tables of the ghg dataset tables of the ghg dataset data modeling data models were created using dbt developed in dbt cloud sql techniques used ctes window functions for calculating running total moving average delta values yoy rank various joins unions intermediate models were stored in stg dbt models stg subfolder and deployed in analytics stg dataset of the bigquery project there are models focusing on evaluating data quality stored in data quality dbt models

were analyzed and visualized in google looker studio the full datasets included greenhouse gas emissions data from 1990 until 2020 the development dataset was just a fraction of that further described in the following text the full google looker studio report can be found here https lookerstudio google com reporting d80d2d2d 9fb4 44df 8e47 020009182925 datasets comparison overview assets looker analysis png datasets comparison overview datasets comparison overview detailed description of the development process 1 context even though this is just a test project let s build some real foundations for its justification the scientists have already discovered in several studies that if the trend of global warming continues there will be pretty bad consequences for human kind since we haven t invented any tools or mechanisms to cool down the planet the only possible action we can take is to lower the amount of emitted greenhouse gases that contribute towards the warming of the planet one of the areas that might be ideal for optimisation is the food consumption usually it s almost no problem to get the products we want at a certain moment even though they were produced on the other side of the planet the food availability causes some unnecessary greenhouse gases emission that are either related to the transportation of the goods or by over production 2 the project goal now the fun part begins as mentioned in the disclaimer there are some assumptions about the datasets and due to simplification some information in this section is made up before making any changes like prohibiting international trade we first want to see the composition of emissions related to different sectors in order to understand the significance of the food production there is also suspicion that countries do not report their emissions correctly in order to look better compared to other countries but luckily there is one organisation that have more precise numbers of emitted greenhouse gases so our goal is also to see how off the countries reports are the goals 1 visualize the proportion of co sub 2 sub equivalent emissions related to agriculture against other sectors 2 compare the data from two different sources and provide some key metrics about the differences there are several gases that are generally considered as greenhouse each with different magnitude of contribution towards global warming the common method to normalize the numbers is to multiply the values with a constant that is related to that specific gas resulting in an equivalent of emitted co sub 2 sub the multiplication factors that are used in both datasets were taken from the fifth assessment report by intergovernmental panel on climate change further abbreviated as ipcc 3 exploring the data first i had to understand what is the structure of the data and how the comparison of the two different datasets would look like the data about emissions related to agriculture and food systems are maintained by the food and agriculture organization of the united nations and can be downloaded from their website https www fao org faostat en data gt further abbreviated as fao the fao dataset contains not only agrifood systems data but the emissions data of other sectors that some countries have to report to the ipcc as well the second organisation that gathers data about greenhouse gas emissions is climate watch in my simplified scenario this is the organisation with more precise numbers about emissions the data can be downloaded either directly from their website https www climatewatchdata org data explorer or accessed via api https www climatewatchdata org api v1 data historical emissions in order to get a better understanding of the data and how both datasets fit together i downloaded sample data for canada s 2020 emissions from both portals and put them together in a google sheets file https docs google com spreadsheets d 1zcka8kzinzwqkovcgzbc2xnqtrsqdnlt5au4ie9xvla edit gid 0 the results of my findings are in the following two subsections in both cases i was interested only in downloading data for co sub 2 sub equivalents of emitted gases fao data the data in raw format was not very user friendly there was no indication about what are the aggregated numbers and what are individual categories following along with a table that is attached to the methodological note of faostat s emissions totals domain https fenixservices fao org faostat static documents gt gt e pdf i was able to map individual lower level categories to higher level ipcc categories i have therefore introduced the grading system and assigned appropriate level to each item in a dimension table i have made from selecting distinct values of item and item code mapping of fao categories to ipcc sectors assets fao categories mapping to ipcc png mapping of fao categories to ipcc sectors mapping of fao categories to ipcc sectors source faostat key findings 1 some categories might be missing there was no entry for rice cultivation emissions probably because of canada s lack of rice fields 2 emissions for food retail category was present only in aggregated form all gases together but according to the mapping table some elements were part of the energy ipcc sector co sub 2 sub ch sub 4 sub n sub 2 sub o and some were part of industrial processes ipcc sector f gases therefore additional download of the food retail category with all the elements was necessary additional modifications were to be made in the following etl process 3 level 2 items summed up only for agriculture and lulucf ipcc categories in order to allow the drill down feature while still displaying the totals i had to add three new items energy emissions not related to agriculture ippu emissions not related to agriculture waste emissions not related to agriculture that were to be calculated in the following etl process climate watch data the climate watch data contained only the values for similar categories as ipcc categories in fao dataset and more detailed values for energy sector therefore it was ready to be used without any additional changes 4 ingesting data etl python scripts for ingesting both fao and climate watch datasets were deployed as google functions i had some issues with running the scripts with the basic 256 mib memory allocation so i had to increase the allocation to 512 mib probably becasue of the pandas library overview of the google functions for etl process assets google functions png overview of the google functions for etl process overview of the google functions for etl process fao data unfortunately there is no api to access the data automatically and therefore it is necessary to download the data manually but the rest of the etl process was automated i have created a google cloud function that is triggered by file uploaded to a specific google cloud storage bucket climate watch data google cloud function with parameters that are used in api calls to climate watch portal start year end year regions the function transforms the data and uploads them to the google bigquery dataset 5 creating models data models were created using dbt cloud there are references to the mapping google sheets file https docs google com spreadsheets d 1zcka8kzinzwqkovcgzbc2xnqtrsqdnlt5au4ie9xvla edit gid 0 items mapping sheet in this section in order to save the compute resources the initial testing of the models was done on a small amount of data the testing dataset consisted of three countries canada can nepal npl and guinea gin the period covered was 2016 to 2020 data quality models first set of models were designed to test the quality of the data and some asumptions made in earlier part of the project the idea behind testing the data quality is to verify that the values of higher granularity items i call these level 2 items in this project match the items of lower granularity and that the dataset is complete and both levels can be used interchangebly i e some calculations can be based on level 1 items while others on level 2 items discovery of any methodological or process errors made by any of the data collectors faostat and climate watch is not the purpose of this testing therefore if some higher granularity items were not included in calculating the lower granularity items by accident it won t be discovered data from the fao dataset are possible to view from two different angles first one is the ipcc point of view where sum of the detailed level 2 items columns j k of the mapping sheets file should match the related level 1 items second one is the fao point of view which has different level 1 categories columns n o of the mapping sheets file that are composed of only some of the level 2 items climate watch dataset has entries that can be linked only to the fao s ipcc categories columns d e of the mapping sheets file therefore the data quality models covers only one dimension results of all the data quality tests were combined in one master table only one of the tests was showing errors results of all data quality tests assets data quality master result png table that includes results of all data quality tests results of all data quality tests however the errors were pretty insignificant and i didn t catch any calculation error i tested one random example and the numbers were correct errors of fao fao test 1 model assets fao fao test 1 result png errors of fao fao test 1 model errors of fao fao test 1 model core models the key analytical data models that aim to compare the fao data and climate watch data they were built on top of raw data in the ghg bigquery dataset as well as intermediate models materialized as tables and stored in analytics stg dataset the main data model datasets comparison per country and year basis has several calculated columns cw value aggregated value of level 1 items of all ipcc sectors from the climate watch dataset fao value aggregated value of level 1 items of all ipcc sectors from the fao dataset values difference difference between cw value and fao value negative value implies that values reported in faostat were lower than those in climate watch relative difference the values difference value divided by the fao value running total difference sum of values difference values for the year on the current row and all of its preceding years ma5 values difference moving average for 5 values current row value 2 preceding and 2 following cw yoy difference yoy difference of cw value fao yoy difference yoy difference of fao value 6 analysis and visualization the data models outputs were finally used as a data source for google looker studio report datasets comparison one of the project s goals was to compare the datasets for that i have selected relative difference as a comparison metric from the metric and the line chart it is clear that the emissions reported in climate watch were in general higher than in faostat therefore my hypothesis about contries not reporting the emissions corectly was not confirmed however there were some countries that had positive relative difference top 5 are displayed at the lower half of the page datasets comparison page assets looker datasets comparison full png datasets comparison page datasets comparison page agrifood systems
