海外TECH	DEV Community	Free Push-To-Talk Android SDK awaits your implementation	https://dev.to/voicepingapp/free-push-to-talk-android-sdk-awaits-your-implementation-hnf	Free Push To Talk Android SDK awaits your implementationNothing is better than a good quality product and it is free We Smart Walkie Pte Ltd have been developing walkie talkie Push To Talk software for years with all the hurdles and obstacles we faced to bring the best solution to our users who come from all over the world countries Now we proudly announce that you can take and use some of our good work in the form of open source Android Software Development Kit SDK and open source server that you can self host This is our contribution to the community whom we owe Oftentimes we take info and get answers from the community And we solve some of our problems using the open source software from the community too So this is our “thank you to the community which might also include you What is Push To Talk The simplest explanation for Push To Talk is walkie talkie functionality When we want to talk in a walkie talkie we need to push a button and hold it Then only we can be heard instantly by other people on other walkie talkies When we are done talking we need to release the button In a walkie talkie when we talk we can t hear others and vice versa when we hear we can t talk That s where the Push To Talk term comes from It s often abbreviated as PTT So what is Push To Talk SDK Software Development Kit SDK is a piece of software that can be directly integrated into another software to enrich its functionality PTT SDK offers the capability to add walkie talkie PTT functionality into your software VoicePing PTT Android SDK helps you add PTT functionality to your android app It will not be limited by range like the old walkie talkie As long as the devices have internet connection even if one device is in the Earth s south pole and one other in the north pole they will be able to talk to each other seamlessly Why would you need PTT functionality PTT conforms to human direct verbal communication It s fast and instant The exact way we talk to others and others talk to us Text messages compared to PTT take more time to write and to be understood Although text has its own power in a special context which is silence more private clarity and light in data storage and transfer But most of the time we use too much text messaging outside its specialty causing us to lose time just to convey non private or non sensitive information to the other party PTT also has its own power which is instant and interruptible Hence PTT is often used in Search and Rescue SAR like activities because the communication needs to be instant hassle free over a long period of time no need for action to pick up to hear the message and reliable It s different than a call which takes time to get picked up first needs an opening word smalltalk closing words and parties involved need to spend high focus and attention to communicate and respond What can you build with a PTT SDK Imagine you drive a car in convoy There are cars including yours Only the front most car driver knows the direction Sometimes you are not right behind your convoy but separated by other vehicles on the road When the first car turns right and you lose sight what would you do Send a text message to the first car s driver Or call None of this is suitable in this kind of situation because seconds matter in decision Which results in total driving time your convoy will have Now imagine you have an app on your phone that has walkie talkie PTT functionality You plug an earpiece to it and you drive Along the journey when there is road branching the first driver always PTT other drivers which way to take It can be heard instantly without any action If a problem occurs you can also PTT others by pressing the earpiece button to tell them so they can stop wait for you or even search to help you The communication is as simple as pressing the button It s easy fast and instant Yes you can build that kind of app with VoicePing Walkie Talkie Android SDK That is just one use case where PTT is irreplaceable You can find many other PTT use cases on our website How to taste the service before you go too deep You have two options First is by trying out free public channels on VoicePing apps below VoicePing WebVoicePing AndroidVoicePing iOSJoin the same free public channel ID to communicate between devices Second is by trying the VoicePing SDK demo apk The demo apk source code is also available on the VoicePing Android SDK repository to guide you on how to use or integrate the SDK to your android project Where should you go for more details if you want to use VoicePing Android SDK If you want to know more we have the documentation page here It mainly has two parts First is the Android PTT SDK itself The Android SDK needs VoicePing router server to work We have our public server for you to test and use If you need to self host the server on your own the second part of the documentation is the guide on setting up the self hosted server Who can use VoicePing Android PTT SDK Basically everyone since we put the code under MIT license That means you are free to use the software including for commercial purposes Who maintains the open source code The developers at Smart Walkie Pte Ltd are full time maintainers of the code So if you have issues or find bugs don t hesitate to report to us We also welcome all contributions from the community not just code but any contribution for example updating the documentation or hinting a typo What if you need more support beyond the open sourced functionality offers If you need further support we can help you in any way Please contact us at sales smartwalkietalkie com See more about this here If you are reading up to here thank you for your kind attention We can t wait to know what you will build with the VoicePing Walkie Talkie Android SDK Let us know in the comments section below or on the github discussions page We hope that this contribution of making a free open source PTT SDK will help the community overall to save time both software development wise and communication wise Finally even when VoicePing Android Walkie Talkie PTT SDK brings the possibility of instant communication what also matters is our own communication skill to convey information effectively The app is just a tool the tool itself doesn t change certain aspects in life But how people use it does change certain aspects in life “Communication is a skill that you can learn It s like riding a bicycle or typing If you re willing to work at it you can rapidly improve the quality of every part of your life Brian TracySmartwalkie Smart Walkie Pte Ltd is a company that works on both hardware and software of Push To Talk PTT solution VoicePing is the software part of it We help many industries all over the globe on their communication

海外TECH	DEV Community	Code compiling: Explain like I'm Five	https://dev.to/arikaturika/code-compiling-explain-like-im-five-4mkj	Code compiling Explain like I x m FiveComputers can only understand machine code which is a low level programming language generally being made up entirely of numbers Most of the time when people talk about machine code they refer to it as binary code a number system with base either a or So we can say that machine code is made out of sequences of ones and zeros Below there s a snippet of some binary code We need to comunicate with computers so in order to do so we need to speak their language But writing machine code is very impractical so we had to come up with languages that resemble our own language We call these languages higher level programming languages Some examples are Python Ruby C or Java Now the problem is that computers do not understand these languages directly so we need a translator that can explain our instructions to the computer This is how compilers and interpreters were born They are programs that translate the code we write using higher level languages into machine code Compiling means that after we finished writing our code a compiler a program takes our code and looks at it making sure it has been written acording the rules of the programming language we used it checks for syntax errors If no mistakes are found the code can be effectively translated into machine code and a file containing compiled code is generated We hear people saying that the code doesn t compile This means that while checking the code the compiler found errors and the translation into machine code wasn t succesful Usually the programmer will see some error messages that will help them debug the code Only after all errors are fixed the code will compile IMPORTANTJust because the code compiles that doesn t mean the program works This is because a compiler can t catch logical errors It might sound counterintuitive but think about it like writing an English text with no grammatical errors or typos so the words are correct on their own but when read together they make no sense Low level programming languages are languages that sit close to the computer s instruction set An instruction set is the set of instructions that the processor understands Machine code can be represented using other number formats like hexadecimal These formats are easier to read by humans but the computer can t understand them so in the end they also get converted to binary Interpreters are also used to translate source code into machine code but they work differently from compilers	2022-04-14 09:07:20

海外TECH	DEV Community	OAuth vs JWT (JSON Web Tokens): An In-Depth Comparison	https://dev.to/supertokens/oauth-vs-jwt-json-web-tokens-an-in-depth-comparison-5gnp	OAuth vs JWT JSON Web Tokens An In Depth ComparisonAuthentication is one of the core functions of applications on the internet today one that many developers are familiar with Yet actually implementing authentication correctly requires understanding several standards and protocols Two of the most important of these authentication standards are OAuth and JWT JSON Web Tokens Looking to make sense of OAuth and JWT You re in the right place In this article we will cover What OAuth is and the Pros and Cons of using itWhat JWT JSON Web Tokens is and the Pros and ConsHow to use OAuth and JWT together effectivelyLet s dive in What is OAuth OAuth Open Authorization often written as the latest version OAuth is a protocol that is used to authenticate a user via an authentication server One of the useful things about OAuth is that it enables you to delegate account access in a secure way without sharing credentials Instead of credentials OAuth relies on access tokens Using access tokens a client application can verify the identity of the user that authenticated themselves Visually the process looks like this When you implement “Sign in with Google or “Sign in with Github you are using the OAuth protocol Pros of using OAuthWorking with OAuth has some great benefits including It s the accepted industry standard This means that most authentication services will understand and use OAuth There s many plug and play OAuth options Including services like “Sign in with Google and “Sign in with Facebook that are already set up to be consumed within your application OAuth has well tested client libraries in almost all languages and web frameworks This means that your language of choice can be used with OAuth It allows for decoupling of code Your client application code is not affected by the authentication code OAuth is very secure and battle tested Due to its widespread nature you can be rest assured that all security edge cases have been thought about by industry experts Potential considerations of using OAuthWhile OAuth is a great standard there s a handful of things to be mindful of when using it OAuth can be complicated to understand if you are unfamiliar There are several different OAuth flows and deciding which is right for you can be a challenge Sometimes you may even need to use multiple flows It has lower end user privacy The auth server knows all the sites that the end user has logged in into For example when a site uses Sign in with Google Google would be able to keep track of when that site s users are signing in or are active It s overkill in certain situations If you are building a simple webapp that has one frontend and backend then you don t need the OAuth protocol However a lot of online tutorials and ready made auth solutions force you to implement this No session management solution Once the user is authenticated the auth server simply returns a JWT which can be consumed by your application as well will see later However after that step the OAuth protocol doesn t provide any support for specifying how to maintain the authenticated session between your app s frontend and backend this is totally up to the developer What is JWT JSON Web Tokens A JWT is a token that is generated by the authentication server and contains the end user s information like their userID email etc The information is in JSON format and can be efficiently verified by the client application using cryptography So when exactly is using a JWT appropriate JWT is best used whenever you want to transmit some information to an untrusted client in such a way that that client can verify the information contained in the payload themselves From the context of an auth server an untrusted client is the application that the user is trying to use From the context of the application s backend an untrusted client is the frontend code Pros of using JWTThere s some good reasons JWT is such a popular standard They are self contained The JWT can contain the user s details So you don t need to query a database auth server for that information on each request They offer strong security guarantees JWTs are digitally signed which safeguards them from being modified by the client or an attacker JWTs are stored only on the client You generate JWTs on the server and send them to the client The client then submits the JWT with every request This saves database space They are efficient and quick to verify This is because JWTs don t require a database lookup Potential considerations of using JWTWhile JWTs are incredibly useful it s helpful to keep the following things in mind You can t revoke them without putting in a lot of extra engineering effort This is because there is no db call when verifying them In order to implement immediate revocation you would need to implement JWT blacklisting which can be time consuming It s easy to create security bottlenecks while keeping one secret safe If the signing key is compromised the attacker can use that to create their own valid JWTs This would allow them to spoof the identity of any user an application Better together How to use OAuth and JWT togetherWe ve learned that OAuth and JWT are powerful standards for building authentication flows in applications As it turns out OAuth vs JWT doesn t have to be either or they can be used together When the authentication server successfully verifies a user s credentials via OAuth it also needs to transmit the user details to the client application In order for the client application to verify the details JWTs can be used to ensure an efficient process This works by the OAuth server sending a JWT to the client after the OAuth flow is complete containing the end user s information A typical JSON payload in the JWT sent by the OAuth server looks like the below example from sign in with Google iss azp apps googleusercontent com aud apps googleusercontent com sub at hash HKE PDhYmRNtsDBQ email jsmith example com email verified true iat exp nonce hd example com What do all these fields mean Below is a quick summary using this particular example iss The issuer of the token in this case Google azp and aud Client IDs issued by Google for your application This way Google knows which website is trying to use its sign in service and the website knows that the JWT was issued specifically for them sub The end user s Google user IDat hash The hash of the access token The OAuth access token is different from the JWT in the sense that it s an opaque token The access token s purpose is so that the client application can query Google to ask for more information about the signed in user email The end user s email IDemail verified Whether or not the user has verified their email iat The time in milliseconds since epoch the JWT was createdexp The time in milliseconds since epoch the JWT was creatednonce Can be used by the client application to prevent replay attacks hd The hosted G Suite domain of the userAs you can see there is a lot of information transmitted from the OAuth server Google in this case to the client application It s worth mentioning that some of the fields in the above JSON payload are specific to Google like hd Other providers may have similar and have different content Since this is all in a JWT the client application can verify the contents of this JSON and know that no one has manipulated this content Final thoughtsOftentimes we see developers asking whether to use “OAuth or JWT for their authentication setup In reality OAuth and JWT are two different standards with different uses which can be used together with great effect In fact JWT is often used as part of the OAuth protocol At SuperTokens we provide an auth solution that mitigates most of the cons of using OAuth and a JWT including We encourage the use of OAuth only when really needed We offer a way to revoke JWTs access tokens easily without reducing the verification efficiency We offer a secure session management solution which is the missing piece in the OAuth protocol Want to learn more about authentication OAuth or JWT Or You have any questions please join our discord server here	2022-04-14 09:01:28

GCP	Cloud Blog	A policy roadmap for 24/7 carbon-free energy	https://cloud.google.com/blog/topics/sustainability/a-policy-roadmap-for-achieving-247-carbon-free-energy/	A policy roadmap for carbon free energyIn Google set its most ambitious sustainability goal to date By we aim to operate entirely on carbon free energy CFE ーaround the clock ーat our data centers and offices worldwide This means matching each hour of our electricity consumption with carbon free electricity sources on every grid where we operate  Securing round the clock carbon free energy isn t just important for Google it s also critical for the world to successfully tackle the urgent challenge of climate change The electricity sector is the linchpin of this effort as it is both a significant contributor to global carbon emissions and a tool to enable the decarbonization of other parts of the economy such as buildings transportation and heavy industry  When Google announced our CFE goal we identified three ways to advance toward it First develop new transactional approaches for buying clean energy around the clock Second support the commercialization of next generation clean energy technologies and develop smart solutions for managing electricity demand Finally develop partnerships and advocate for policies that accelerate the decarbonization of electricity grids across the world  This last pillar is critical to achieve CFE both for our own operations and for economies more broadly we must do more than just purchase clean energy ーwe must work to transform electricity systems That change can only happen if we work collaboratively to reform the policies and regulations that have shaped the electricity industry for more than a century That s why today we are releasing a new clean energy policy roadmap informed by over a decade of experience as a large electricity user and major clean energy buyer across the globe  While rapid progress in cost effective carbon free energy technology has put the prospect of decarbonized electricity grids within reach it is not inevitable this transition will be slower more expensive and less certain without the right public policies We are committed to working with stakeholders across the globe to advocate for policies that accelerate grid decarbonization for everyone Policy priorities for grid decarbonizationOur policy roadmap identifies three core goals ーadvance technology expand and reform markets and empower consumers ーthat policymakers should prioritize to accelerate the transition to a reliable cost effective inclusive and carbon free electricity system  Advance technology Policies should support the development commercialization and deployment of a broad portfolio of carbon free energy technologies maintain existing carbon free resources and speed the replacement of carbon emitting ones These policies include clean energy standards CFE investment incentives and measures that remove barriers to the electricity transmission infrastructure that is critical to cost effectively deliver clean power from where it s generated to where it s needed  Expand and reform markets As a major electricity buyer across dozens of regions worldwide our experience has taught us that regional and competitive wholesale electricity markets are key vehicles to accelerate clean energy adoption and lower costs for electricity consumers Policymakers should work to create and expand regional and competitive wholesale electricity markets where they don t exist today They should also reform markets to value the contribution of all carbon free energy sources and to move towards models that are more integrated and flexible across supply and demand Empower consumers Policy reforms are needed to unleash the power of customer demand to accelerate the clean energy transition This means creating legal and cost effective pathways to clean energy for all consumers providing customers access to transparent granular high quality energy data and designing regulatory structures that incentivize consumer participation For example policymakers can support the development of time based energy attribute certificates T EACs that can enable consumers to increase their decarbonization impact  Working together to advance clean energy policyIdentifying the right policies is only a first step To drive the policy and market changes needed over the next decade will require hard work from everyone including the private sector We all have a stake in the policies and regulations that shape electricity systems and we must use our voices and organize around the common objective of complete rapid and cost effective decarbonization This is why Google worked with our partners at UN Energy and Sustainable Energy for All to launch the global Carbon free Energy Compact ーa set of commitments and actions from energy buyers energy suppliers governments system operators solutions providers investors and other organizations to advance CFE It s also why we ve been a vocal supporter of legislation to advance clean energy in the United States and other countries around the world  As we advance toward our goal of CFE by we commit to working with others and advocating for clean energy policies that enable CFE for all energy consumers and decarbonize electricity grids at the scale and pace required to meet the urgency of the world s climate challenge Please join us to create a carbon free future To learn more about how to engage with us and accelerate the transformation of electric grids globally visit gocarbonfree comRelated
