海外TECH	DEV Community	Automated Customer Care Rating	https://dev.to/amoghsingh25/automated-customer-care-rating-1k82	Automated Customer Care Rating Innovative Ideas Challenge IntroductionThe Innovative Ideas category was an ideal choice for me as I was interested in pitching a project that would be useful and allow for quicker results and more accurately Before taking part in Deepgram Hackathon I have had a bit of prior experience with Speech Recognition Technology mainly out of curiosity and exploration My Deepgram Use CaseMy inspiration for this submission comes from customer care centers where the executives are often helpful but there are cases where executives are rude to their customers which has a negative impact larger than the positive impact made A single bad experience can spoil a customers relationship with the organization company and in the long run can be harmful to business Deepgram can be used here to generate transcripts of the call recordings usually stored by the customer care centers and appropriately evaluate a executive s efficiency and their talking style with customers Upon exploration of the Deepgram website and their API documentation I found a few use cases of call transcription and realized this would be an ideal use case for Deepgram and therefore chose this particular topic Dive into DetailsCustomers are the utmost priority for any company or organization and they must be treated so especially when they seek help from a customer care But there are cases where customer care executives are rude to a customer This is where Deepgram comes into picture Deepgram can be used to convert those call center recordings to text which can then be processed by a Machine Learning model to generate the general emotion of the customer care executive through the words they chose and the emotion of the reply given by the customer This can then be used to score and better train the executives to handle customers well and allow for a better service to the end customer This method takes into consideration the emotion or attitude of the customer as well as the executive to better judge the executive and can be utilized appropriately to eliminate cases where the customers are being rude with no fault of the executive ConclusionHaving gone through the Deepgram documentation it can certainly achieve the task of call transcription and coupled with Machine Learning models for emotion detection it could be used for efficient handling of customers and training of customer care executives The idea of speech recognition and the extraction of emotion through text is the two main components of this idea with both of them being highly researched and now widely used technologies for various use cases ranging from hate speech detection to captions generation Through the course of research for this project I feel that with the combination of these two technologies there are many more applications which can be devised and used to automate simple tasks like the one discussed	2022-04-09 22:13:24

海外TECH	DEV Community	5 good computer science books to start if you don't know how to start	https://dev.to/digomic/5-good-computer-science-books-to-start-if-you-dont-know-how-to-start-3m26	good computer science books to start if you don x t know how to startComputer science is the study of computers and computational systems It is also a branch of engineering mathematics and science Computer scientists research and develop new computer technologies They design software networks and other computer based tools for people to use Computer scientists may develop programs that help solve specific problems or automate processes They may create games or other types of entertainment software that people can use to have fun on their own or with others Some computer scientists work on the design of chips the microchips that are found in devices like laptops They may work in teams to develop new chips for smartphones or tablets Other computer scientists work on improving the security features of computers and networks so they can help protect information from being stolen by hackers How Computers Really WorkHow Computers Really Work is a hands on guide to the computing ecosystem everything from circuits to memory and clock signals machine code programming languages operating systems and the internet But you won t just read about these concepts you ll test your knowledge with exercises and practice what you learn with optional hands on projects Build digital circuits craft a guessing game convert decimal numbers to binary examine virtual memory usage run your own web server and more Explore concepts like how to •Think like a software engineer as you use data to describe a real world concept•Use Ohm s and Kirchhoff s laws to analyze an electrical circuit•Think like a computer as you practice binary addition and execute a program in your mind step by step Introduction to Computer Organization Introduction to Computer Organization gives programmers a practical understanding of what happens in a computer when you execute your code You may never have to write x assembly language or design hardware yourself but knowing how the hardware and software works will give you greater control and confidence over your coding decisions We start with high level fundamental concepts like memory organization binary logic and data types and then explore how they are implemented at the assembly language level The goal isn t to make you an assembly programmer but to help you comprehend what happens behind the scenes between running your program and seeing “Hello World displayed on the screen Classroom tested for over a decade this book will demystify topics like •How to translate a high level language code into assembly language•How the operating system manages hardware resources with exceptions and interrupts•How data is encoded in memory•How hardware switches handle decimal data•How program code gets transformed into machine code the computer

海外TECH	DEV Community	Secure your Kubernetes secrets easily with Trousseau	https://dev.to/mhmxs/secure-your-kubernetes-secrets-easily-with-trousseau-4f1p	Secure your Kubernetes secrets easily with TrousseauThe term of secret in Kubernetes is a bit deceptive I don t want to go into details this time because the internet is full with posts about this problem In really short they are not real secrets because ETCD or any database behind Kubernetes stores the records in plain text without any encryption We have a few options to solve this problem let s start with the easiest one Kubernetes has official support for encrypting secret data at rest It is disabled by default and requires some cluster administration to enable it The cluster admin has to define an EncryptionConfiguration and restart Kubernetes API service with the new config It supports several en decryption methods out of the box It sounds easy like a flick but there are some major issues with the solution Firstly you have to define keys as plain text in the config so keys should be readable for an attacker and rotating the keys is not a trivial task It is easy to admit that this solution is more than nothing but is far away of real secret protection If built in solution is not enough for you you have to choose an external Key Management Service KMS like Hashicorp Vault and somehow inject secret resolution to your workload There are several options you can use a mutation webhook and create environment variables during pod creation for example or use an extra sidecar to resolve secrets inside the container as volumes The main advantages of this way is you have full control where and how encrypted secrets would be converted into readable values but all the coin has an other side The solutions are complex and most importantly they are not transparent Because Kubernetes secrets are just references to the real ones you must configure everything on every single target cluster or have to write tons of if else in your favorite manifest generation tool What if I say there is something in the middle and let me introduce Trousseau Trousseau is an open source tool which combines Kubernetes built in envelop encryption with an external KMS With Trousseau you should use the same secrets as without it in your manifests Kubernetes saves encrypted version of secrets into ETCD but workloads can have the decrypted version in a transparent way Trousseau supports only Vault at the moment others are on the roadmap	2022-04-09 22:03:57
