海外TECH	DEV Community	Migration to .NET Core. Mission Complete	https://dev.to/elanatframework/migration-to-net-core-mission-complete-2bc5	Migration to NET Core Mission CompleteBy using Code Behind Elanat managed to migrate from NET standard version to NET Core version in a very short time Elanat is the largest NET system that migrates from NET Standard to NET Core It is interesting to know that the duration of Elanat s migration from NET Standard Version to NET Core was completed in less than weeks and this is an extraordinary record and a unique success for Elanat We maintain the Elanat source repository of the standard NET version so that its comparison with the Elanat source repository of the NET Core version is an important resource for computer systems researchers In addition to the advantages that NET Core has over standard NET such as cross platform what benefits did the transition to NET Core bring to Elanat The complexity of the add on oriented structure was reducedComplete control over requests and the possibility of changing incoming requests from the client sideIncreased server side independenceThe system became more agile and fasterWe went through a lot of pains to create a add on oriented structure at Elanat But by using the Code Behind infrastructure we left all the complications to bypass the loop which existed in standard NET Fortunately all the data remained unchanged and the source code of the server side also had minor changesFor example the App Data directory remains as a relic of the NET standardChanges Ionic Zip dll was removedZipFileConnector dll was removedPathHandlersLoader aspx was removedPageHandlersLoader aspx was removedAdded a ListItem classWe created some methods that were in standard NET but not in NET using Extension methods and the codes remained intact Example of SaveAs method on IFormFile public static void SaveAs this IFormFile PostedFile string FilePath using Stream TmpFileStream new FileStream FilePath FileMode Create FileAccess ReadWrite PostedFile CopyTo TmpFileStream Code Behind creates the least load on the server and setting the IgnoreViewAndModel attribute to false makes even the Model and View not be called Currently Elanat is fully implemented on NET Core version and is undergoing software testing In August a new version ready to be installed and the source code of Elanat will be provided The codes below show the differences between model view and controller in Elanat NET standard version and Elanat NET Core version These are login page codes and they are a bit long and are provided for computer system researchers and programming

海外TECH	DEV Community	GitLab Dev Deletes Entire Production Database	https://dev.to/kanani_nirav/gitlab-dev-deletes-entire-production-database-59bb	GitLab Dev Deletes Entire Production DatabaseIn this article we ll look at how a developer s mistake caused GitLab to lose six hours of data from their website we ll see what happened at that time how they fixed it and what they learned from it For GitLab and its users this issue was terrible deGitLab is one of the most popular platforms But on January GitLab had a big problem one of their developers accidentally erased the whole production database wiping out six hours worth of data from GitLab com which was one of GitLab s greatest nightmares The Problem Too Much DataThe problem started around pm UTC when GitLab saw that some bad people were making a lot of snippets small pieces of code on GitLab com making the database very busy and unstable GitLab started blocking the bad people by their IP address and deleting their users and snippets Around pm UTC the database got worse making it hard to write anything and making the website go down GitLab saw that one user was using a project as a CDN making IPs sign in with the same account This made the database very busy too They deleted this user as well Around pm UTC GitLab got an alert because the database was not copying itself to another database which is important for backup This happened because there was too much data to copy and the other database could not keep up GitLab tried to fix the other database by deleting its data folder and starting the copy again Mistake Wrong CommandBut the copy did not work giving some errors GitLab tried to change some settings on the main database but this made PostgreSQL not start because of too many things open Around pm UTC one of the developers team member thought that maybe the copy was not working because the data folder was there even though it was empty on the other database He decided to delete the folder using rm rf var opt gitlab postgresql data But he made a big mistake he ran the command on the main database instead of the other one This deleted all the data from the website database leaving GitLab com with no data at all The Solution Use an Old BackupAs soon as team member knew what he did he told his team member and stopped everything on GitLab com They started looking for backups to get the data back They found out that they had some backup methods but none of them worked well The disk snapshots were not turned onThe S backups were not foundThe DB dumps were oldThe copy process was brokenThe only backup that worked was one that team member made by hand six hours before the problem This backup had most of the data from GitLab com but not things like issues merge requests users comments snippets etc that people made or changed in those six hours GitLab decided to use this backup to make GitLab com work again as soon as possible They also asked their users to help them get back any lost data by sending them pictures or copies of their recent work The backup process took a long time and had many steps Putting the backup on a new database serverMaking GitLab use the new database serverChecking and fixing the backup dataStarting GitLab services and testing if everything worksTalking to users and telling them what s going onGitLab com was finally working again around pm UTC on February st more than hours after the problem started The Lesson Learn from MistakesGitLab looked at the problem very carefully and wrote a blog post about it They found out why the problem happened and what made it worse such as Human error team member deleted the wrong folderLack of verification none of the backup methods were tested or watchedLack of documentation there was no clear way to use the backupsLack of communication there was no good way to talk and work togetherLack of sleep team member was working late at night and was tiredThey also made a list of things to do and make better to stop such problems from happening again such as Turning on disk snapshots and checking S backupsMaking backup documents and testing ways betterMaking alerts and watching for backup problemsMaking role based access control and audit logging for database serversTeaching and helping with PostgreSQL copyMaking a blameless culture and a way to learn from mistakesGitLab s problem was very bad for them and their users It showed that they needed to have good and tested backups and a clear and written way to use them GitLab was open and honest about the problem and they shared what they found and learned with everyone They also said sorry to their users and gave them something for the data loss They got a lot of feedback and support from their community who liked their openness and work ConclusionGitLab messed up and lost data but they fixed it and learned from it GitLab s problem is a reminder for all of us who work with data and databases to be careful smart and ready We should always check our commands test our backups write our ways talk with team members and learn from our mistakes ReferenceDev Deletes Entire Production Database ーYouTubeGitLab com database

海外TECH	DEV Community	Unlocking the Power of PyScript: A Guide to Running Python Code in Your HTML	https://dev.to/scofieldidehen/unlocking-the-power-of-pyscript-a-guide-to-running-python-code-in-your-html-2376	Unlocking the Power of PyScript A Guide to Running Python Code in Your HTMLAre you looking for a way to add more interactivity and functionality to your websites Do you want to incorporate machine learning or data analysis capabilities without relying on external APIs or libraries Look no further than PyScript a revolutionary tool that allows you to run Python code directly in your HTML files In this guide we will explore the basics of PyScript showcase some of its powerful features and provide tips and best practices for using it effectively in your web development projects Common Use Cases for PyScript in Web DevelopmentPyScript s versatility and capabilities make it a valuable asset for an array of web development projects Here are some of the common use cases where PyScript excels Data Analysis and VisualizationPyScript enables developers to seamlessly integrate Python s data analysis and visualization libraries into web applications such as NumPy and Matplotlib This empowers developers to present data driven insights visually engaging and interactively Machine Learning ApplicationsWith the increasing prominence of machine learning PyScript offers a powerful platform for integrating Python based machine learning models into web applications Developers can provide real time predictions and personalized experiences to users Interactive Games and SimulationsPython s simplicity and readability make it an attractive choice for game development PyScript allows developers to create interactive games and simulations elevating user engagement and entertainment on web pages Server Side ProcessingPyScript can also be leveraged for server side processing where Python code runs on the server to handle complex tasks and data manipulation This optimizes the performance of web applications and enhances user experiences Getting Started with PyScriptBefore we dive into the nitty gritty details of PyScript let s first cover how to get started with it Installing PyScript is relatively straightforward and there are several methods to do so Using npm Open your terminal and run the following command npm install pyscript This will download and install PyScript globally on your system Using yarn Run the following command in your terminal yarn global add pyscript This will also download and install PyScript globally on your system Manual installation Download the PyScript package from the official GitHub repository and follow the manual installation instructions provided there Once you have installed PyScript you can start using it in your web development projects by simply adding the lt script gt tag to your HTML file along with the PyScript library xml   lt title gt My Website lt title gt    lt script src dist pyscript min js gt lt script gt lt head gt Understanding PyScript BasicsNow that we have covered how to get started with PyScript let s closely examine its core concepts and how they work together At its heart PyScript is a JavaScript library that bridges Python and JavaScript allowing developers to call Python functions and modules directly within their web pages Here are some key points to understand about PyScript Python scripts These are the actual Python files that contain the logic and functionality you want to execute on your web page You can write these scripts using any text editor including any valid Python code including imports functions and classes JavaScript integration Once you have written your Python script you must integrate it into your HTML file using JavaScript This involves creating a lt script gt tag that references the PyScript library and includes your Python script as a string Calling Python functions To call your Python functions from within your web page you need to use the py Script object and specify the name of your function For example suppose you have a Python function named add numbers that takes two arguments and returns their sum To call this function from JavaScript you would use the py object as follows xml lt DOCTYPE html gt lt html gt lt head gt    lt title gt PyScript Example lt title gt lt head gt lt body gt    lt Include the PyScript library gt    lt script src pyscript js gt lt script gt    lt script gt      Call the Python function using PyScript    var result py add numbers     console log result This will print the sum to the browser console   lt script gt lt body gt lt html gt In this example the py object bridges JavaScript and Python allowing you to call Python functions from within your JavaScript code The add numbers function is called with arguments and and the function call result is stored in the variable result Handling return values When you call a Python function from JavaScript you can handle the return values like any other JavaScript function call You can assign the result to a variable or use it directly in your JavaScript code Data exchange PyScript enables data exchange between Python and JavaScript You can pass data from JavaScript to Python functions as arguments and receive data from Python functions back into JavaScript as return values Error handling When calling Python functions from JavaScript it s essential to handle potential errors gracefully If an error occurs in the Python code it will be caught by PyScript and you can handle it using try catch blocks in JavaScript Python module support Besides calling Python functions directly PyScript also allows you to import and use Python modules in your web pages This lets you leverage existing Python libraries and functionality within your JavaScript code It s important to note that PyScript requires both Python and JavaScript environments to be set up properly The Python environment should have installed the required libraries and modules and the PyScript library should be properly referenced in your HTML file Overall PyScript provides a powerful way to combine the strengths of both Python and JavaScript in web development allowing developers to leverage Python s rich ecosystem and JavaScript s versatility for building interactive and dynamic web applications Getting Started with PyScriptTo demonstrate using PyScript in a real life project let s consider a simple web application that performs sentiment analysis on user provided text using a pre trained Python machine learning model We will integrate PyScript into the project to handle the sentiment analysis tasks on the client side sending the text data to Python for analysis and displaying the results back to the user We ll use Flask as the Python web framework for server side implementation for this example Prerequisites Install Flask and PyScript Download a pre trained sentiment analysis model e g using libraries like nltk or scikit learn Project Structure sentiment analysis app   static     pyscript js  templates     index html  app py  sentiment model pysentiment model py sentiment model py Assuming you have a pre trained sentiment analysis modeldef analyze sentiment text     Your code to analyze sentiment

in their respective directories Make sure you have Flask and PyScript installed in your Python environment Download or create a pre trained sentiment analysis model and update sentiment model py accordingly Run the Flask application using python app py Access the web application at Enter some text in the textarea and click the Analyze button to see the sentiment analysis result In this example we used PyScript to integrate Python code the analyze sentiment function into a simple sentiment analysis web application The web application runs on Flask and uses PyScript to call the Python function analyze sentiment from the client side JavaScript The Python function analyzes the sentiment of the user provided text and returns the result to be displayed back to the user on the web page This example highlights the ease of using PyScript to seamlessly integrate Python functionality into web applications making it a powerful tool for real life projects involving Python and JavaScript
