海外TECH	DEV Community	JavaScript : Arrays	https://dev.to/vivekalhat/javascript-arrays-4mkc	JavaScript ArraysVariables can store only a single value at a time but what if you want to store multiple items at the same time It is not efficient to create separate variables to store each item right In JavaScript we can store multiple items together using an array An array is just a list like structure or a container that is used to store multiple elements irrespective of the data type In JavaScript you can create an array as given below let items Apples Bananas Purple true false An array is just a variable that stores a list In the above line we have created an items variable that contains a list of items All the items inside the array have different data types You can create an array of strings numbers boolean objects or a combination of multiple types An array does not care about the type of data that is stored inside it You can also create an array that contains another array such as let items Apples Bananas The syntax for creating an arraylet const var arrayName An array name should not begin with a number An array is created using square brackets Accessing elements from an arrayArrays are zero indexed It means that the first element inside an array is stored at index the second element is stored at index and so on If you want to access the third element then you can do it by using the following expression let items let thirdElement items Now the thirdElement variable contains the value To access an element from the array you have to specify the index of the element inside the square brackets i e arrayName index Since the array is a list like structure you can use loops to access all elements from the array To get the length of an array you can use the length property of an array i e array length forEach looplet items items forEach item gt console log item for each loop is used to access each element present inside the array for looplet items for let i i lt items length i console log items i The above loop will print each item to the console items length contains the value because array contains elements hence the loop will run until the value of i is less than Modifying array elementsWe have seen how to create and access array elements You can also modify the elements inside the array let items Suppose you want to modify the value of the third element and replace it with You can do it by items Now the array will be In this way you can reassign a value to any index inside the array This property of an array is called mutability It means that you can modify the elements inside the array Array Methodslet items get length of an arrayconsole log items length prints add and remove elements from the end of the array push adds element at the end of the array pop removes element from the end of the array add element at the end of an arrayitems push returns items push returns At this point items remove element from the end of an arrayitems pop returns let removedValue items pop console log removedValue prints At this point items check if element is present inside array or notconsole log items includes prints falseconsole log items includes prints true find index of array elements indexOf returns index of the first occurrence of the element lastIndexOf returns index of the last occurrence of the element let box pen pencil eraser pen pen console log box indexOf pen prints console log box lastIndexOf pen prints add and remove elements from the beginning of the array shift removes the first element from the array unshift add element at the beginning of the array let items items shift returns items unshift returns sort sorts an array in increasing order to sort array in decreasing order you have to pass comparison function to the sort syntax array sort let items items sort returns sort in decreasing orderlet items items sort a b gt if a lt b return else if a gt b return else return returns slice returns a portion of array without modifying the array syntax slice start end slice start slice does not return element present at the end index specified let items console log items slice returns console log items slice returns You can learn more about array methods here	2021-07-17 10:43:13

海外TECH	DEV Community	Temperature Monitoring using Python	https://dev.to/mayankpathak/temperature-monitoring-using-python-1bg5	Temperature Monitoring using PythonHello guys so this post is going to be super excited and useful for those who are trying to find and implement some basic projects to increase and upscale their technical skills and knowledge Here is one of the simple projects which I did during my college project season and it is super useful and easy to implement with basic knowledge of python and some of the technical tools you can try out this project and can also list it to your Resume or CV you can also take this project and show to your project s coordinator during your project season What s the Project About The project is about the Temperature Monitoring where we will monitor the temperature of a closed environment for example like a closed room Since Environment temperature should be a comfortable one where the people can work comfortably and can go up to their efficiency and can work comfortably whether it is machinery or manpower One of important factors that are needed be monitored is the temperature and humidity of the room because if any one of the two goes mismatching it creates an unpleasing and uncomfortable environment Where it can be useful This project has so many uses from a real time perspective let me list some of the uses It can be useful in a room where s temperature needs to be in between certain range A factory or industry where people cannot present at all the time and there s temperature need to be fixed between certain range While transporting some of the goods where they need to be in certain temperature range with limited power supply Hence these are some of the useful parts of the project where it can be implemented with full control over the temperature and best results Let s know the Project in DetailControlling temperature of a controlled environment is an important aspect of any workspace whether it is a commercial space or a domestic space If temperature or humidity is either increased or decreased of any area it becomes very difficult to be there and thus if possible should be kept in comfortable conditions at all times One way to do it is to monitor and control the temperature of the closed surroundings using the concepts of Machine Learning and IoT This research s purpose is the same to find an easy and an inexpensive way to find an alternative to it which is based on microcontroller a Wi Fi Module Buzzer few Temperature sensors and a Solderless board The system is designed in such a way that the temperature can be monitored whether it is in the given range of temperature as prescribed by the user We are also enabling to predict the temperature which will predict the temperature according to the temperature graph being made as by the input taken by the Temperature Sensors using Polynomial Regression Algorithm Also if the temperature of the enclosed area is not in the threshold range as suggested by the user the System will automatically send a notification to user s via SMS E Mail or even through a Telegram Channel Note To do this project completely you will need some technical tools and access to some of the software and online services Introduction The main scope of this project is to measure the temperature of a closed environment let s say we want to measure the temperature of a room Basically a range is fixed that is the minimum and maximum temperature values are fixed and if the measured value is not in this range then the system alarms and sends a notification to the user s device through SMS email telegram etc Components required to work the project Bolt WiFi Module microcontroller LED generic Buzzer to alarm the area Jumper wires generic LM temperature sensor Breadboard generic We are using Z Score analysis which also help in detecting the anomaly of the temperature sensor which means a variable s value going beyond a certain range of values upper and lower bound These bound can be calculated using input values frame size and multiplication factor where frame size is minimum number of input values needed for Z Score analysis and these predictions as well as the old values all will be plotted on a graph which the user can easily understand what could be the next game of plan So we going to use a formula to find any kind of anomaly that can happen in the proposed system So in the above listed formula r Frame Size C Multiplication factor To do so and implement the project you have to register at a platform called Twilio this will help us to get the notification on the device Creating amp Setting up an account on TwilioTwilio is a rd party PaaS Platform as a Software company that provides cloud communication It uses web APIs to make calls and send and receive messages to registered mobile numbers The following gives step by step instructions to create a Twilio account URL Go to Sign up You will find the welcome page Here click on the Sign up for free option Basic steps include Register gt confirm mobile number gt setup required function to carry out gt Configure the file with the required private fieldsAfter this follow the steps as asked from verification till the project creation and in the project section ask to send notification to your device on the Twilio platform You can refer this guide if you encounter any problems but make sure to go for only free access option during Signup Twilio Guide ‍Codes to implement the ProjectMake sure to change the configurations and

海外TECH	DEV Community	Backing up Appwrite to Backblaze	https://dev.to/meldiron/backup-appwrite-to-backblaze-476n	Backing up Appwrite to Backblaze Table Of ContentsIntroductionGetting Backblaze secretsB CLI basicsAppwrite MariaDB BackblazeAppwrite Docker Volumes Backblaze Introduction Recently Appwrite has released an article on how to backup and restore all data on your production server You can read it here Appwrite In Production Backups and Restores Bradley Schofield for Appwrite・Jul ・ min read webdev opensource devops tutorial This article got me thinking Sure you can backup most MySQL databases into a simple backup sql file but what if you have multiple massive projects inside Appwrite Your disk storage may or may not be able to hold a backup of all Appwrite volumes Additionally you most likely need to backup periodically and need multiple versions of the backup So what are your options Write a complex bash script to keep last three versionsThrow all backups to a storage provider and let them take care of itYou should go with storage providers not only because they have a retention system already in place also due to their experience in the field as they most likely care about security a lot and use raids to ensure your data won t get lost I wrote this article as I was implementing this on my own production server and I will show you everything you need to know about backing up Appwrite into Backblaze Getting Backblaze secrets First things first what is Backblaze Backblaze is one of the most if not most used commercial platform to backup your data for the lowest price possible They provide solutions to backup your personal computer or your business data The service we will be using is B Cloud Storage as this gives our flexibility just like an actual hard drive You don t have to worry about pricing yet because their free plan gives you GB of free space To learn more about this product and its pricing you can take a look at Over one exabyte of data storage under management and counting Backblaze websiteAfter creating an account and logging in make sure to confirm your email Backblaze may ask you to set up FA using your phone number for additional security To use Backblaze from our server we will need BUCKET NAMEACCESS KEY IDAPPLICATION KEYBackblaze uses buckets to store your data In our case we will only need one bucket as we will only back up two or three files at most MySQL database and Appwrite Docker volumes To create a bucket navigate to Bucket and press Create a Bucket Give it some name such as appwrite and click Create a Bucket again You should see a newly created bucket on your list Make sure to mark your Bucket Name as we will need this later If you enter App Keys you can Add a New Application Key For simplicity we will ignore that and we will use our master key to have all permissions Simply click Generate a New Master Application Key and this should give you keyID and applicationKey Wohoo we have all secrets we need let s continue B CLI basics To make sure everything is working let s try some simple action on B List files in a bucketUpload a fileList files againWe need to have B CLI installed on our machine but this can be easily avoided thanks to a Docker image mtronix b cli This is the only image I could find that was actually working To list all files in our bucket we run docker run rm mtronix b cli bash c b authorize account lt ACCESS KEY ID gt lt ACCESS KEY ID gt amp amp b list file names lt BUCKET NAME gt The output should be an empty list of files files nextFileName null Let s upload a file We need to have a file I downloaded a cute cat image and saved it as cat png To upload the file I run docker run rm v PWD b mtronix b cli bash c b authorize account lt ACCESS KEY ID gt lt ACCESS KEY ID gt amp amp b upload file lt BUCKET NAME gt cat png cat png The successful result should look something like action upload fileId zdacdadba ffeca d m c v t fileName cat png size uploadTimestamp Finally run the list file names command from above again and you should see your file in the array of files files accountId acd action upload bucketId dacdadba contentLength Backblaze let you do all of this function manually on their website Exercise for you Remove our test file from the bucket Do it however you want you can remove it using B CLI or manually on the website Appwrite MariaDB Backblaze To create an Appwrite MariaDB backup you run this command docker compose exec mariadb sh c exec mysqldump all databases add drop database u MYSQL USER p MYSQL ROOT PASSWORD gt dump sql Source Appwrite article mentioned earlier To backup this export into Backblaze I created a script that Export MariaDB data to dump sqlUpload dump sql to BackblazeRemove dump sql to free up the space on the machineThis is what the script looks like docker compose exec mariadb sh c exec mysqldump all databases add drop database u MYSQL USER p MYSQL ROOT PASSWORD gt dump sql docker run rm v PWD b mtronix b cli bash c b authorize account lt ACCESS KEY ID gt lt ACCESS KEY ID gt amp amp b upload file lt BUCKET NAME gt dump sql dump sql rm dump sqlEach time you run this script it will backup your MariaDB database into Backblaze Backblaze can store multiple versions of a single file just make sure to configure retention on a bucket for example days Appwrite Docker Volumes Backblaze Once again let s get our base command from Appwrite s article Before running these commands is it highly recommended to shut down your Appwrite instance to ensure you get a complete backup mkdir p backup amp amp docker run rm volumes from docker compose ps q appwrite v PWD backup backup ubuntu bash c cd storage uploads amp amp tar cvf backup uploads tar mkdir p backup amp amp docker run rm volumes from docker compose ps q appwrite v PWD backup backup ubuntu bash c cd storage functions amp amp tar cvf backup functions tar These two commands will backup two different volumes The first one back up all files in Appwrite storage while the second one backup your function tags Let s start with backing up uploads Just like with MariaDB we will Create a backup in backup uploads tarSend the file to BackblazeRemove the backup fileThe full command to do this is mkdir p backup amp amp docker run rm volumes from docker compose ps q appwrite v PWD backup backup ubuntu bash c cd storage uploads amp amp tar cvf backup uploads tar docker run rm v PWD b mtronix b cli bash c b authorize account lt ACCESS KEY ID gt lt ACCESS KEY ID gt amp amp b upload file lt BUCKET NAME gt backup uploads tar upload backup tar rm dump sqlThis should create a file called upload backup tar in your Backblaze bucket Exercise time You will need to backup Appwrite functions too Using all knowledge from this article you should be able to prepare a command that will do it If you are here only to copy amp paste commands here is the command Command to backup Appwrite function to Backblaze mkdir p backup amp amp docker
