海外TECH	DEV Community	I show you how to Crack a .NET Application (3 clicks)	https://dev.to/dotnetsafer/i-show-you-how-to-crack-a-net-application-3-clicks-47ke	I show you how to Crack a NET Application clicks ️Disclaimer This article is for educational and training orientation we are not responsible for the misuse of the techniques and explanations mentioned in this article and or the use of the tools mentioned provided also we do not assume responsibility for the actions carried out with the information of the same Please use this information for ethical purposes Hello to all developers I am Juan and I am part of the Dotnetsafer team I do this article for a very simple reason in our offices a co working space there are quite a few companies that develop in NET and one day at lunch I commented what we were doing and they did not understand anything it turns out that they had no idea what decompilation is They did not know that with a simple tool you could see copy or modify its development ーnot in all cases you should be concernedーbut for some of them the core of the business is the development itself and obviously it did not do much grace I have to say that this happens in all compiled languages but I will focus on NET which is what we master In this article I am going to show basic notions about de compilation and reverse engineering if you are interested in something more complex do not hesitate to ask us Note To carry out the practical parts we use DnSpy but we provide you with the same tool from so that you can carry out the tutorial from your browser without having to download anything Simply to decompile drag the applications to the left part shown on the screen the code will be displayed on the right part What is de compilationDe compilation is the reverse of compilation I m going to patent this great explanation That is the COMPILATION is basically You write codeYou push the magic compile button and it becomes an executable file exe dll Well it should surely you forgot a semicolon or something like that you will also have warnings but if you don t open your eyes you don t see them The process will be something like this Well de compilation is the opposite you have an executable file dll exe and with a tool decompiler you get the original source code And is it simple I d say it s easier than compiling but let s see how it s done Decompiling a NET NET Core applicationLet s decompile a simple application For this example we will use DnSpy There are several tools and each one is good for something in particular but DnSpy is one of the best for decompiling and debugging NET applications When we compile our NET Core application we will obtain the compiled files in the case of NET Core the exe file will be the executable but it will be in charge of executing the dll that contains the code of our application Ok let s proceed to decompile the dll file To do this all we have to do is drag it to DnSpy Once loaded the original source code will be shown and we can work on it we can analyze it modify it debug it etc Viewing the source codeOnce our application is decompiled we can navigate through the source code as if it were our own project Debug the appThis will be useful to understand how it works or to obtain some values in memory For example let s put a breakpoint before doing a subtraction and then we will run the application Here is a simple example This is a function that can be very useful at times but it can also be dangerous Modify the codeWe can modify and re compile the application without any problem We can also do it using IL code but if we do not know it it will be much more complex We change that simple text and we compile again Now to save our modified application we will give We will select the name of the file its path and we will mark the following options and we will have our modified application Ok these are simple and unimportant examples I leave to your imagination everything that could be done with these simple tools Now we are going to see other types of applications because compilation in NET is the same it does not matter if you use c vb ASP Xamarin Blazor everything works in the same way let s see then with a Blazor application Decompiling a web application with BlazorNow we have created a sample web application with Blazor this is the application code in visual studio Basically it is an application that shows the weather and we have added Dotnetsafer in the middle so that we can see it later in the decompiled application here is the web application Ok let s get the code again First we will use our browser it does not matter which one since when loading the NET libraries to display the application it makes a call to obtain them We must enter inspection mode Ctrl Shift C and go to section Network later reload the page with Ctrl F Here will be the file that contains the code of our web application You can also obtain all the dependencies or own net files that are used by the applicationWell we download it and open it again with DnSpy Once we have the decompiled file we can do everything that I mentioned in the previous point Decompiling a mobile app with XamarinWe raised the level of difficulty a little but the operation is still the same We have created a simple application for mobile devices with Xamarin the compiled application will have the extension APKThe first thing we will do is unzip the APK there are tools for this but it is not necessary for something so simple we can use winrar yes the program that never expires and we will copy all the files in a folder Inside the folder Assemblies all NET files will be found Here comes the interesting thing these files have lz compression which will give us an error if we try to decompile it with DnSpy For this I bring a simple solution a small Python script that will help us decompress all the NET dll files Yes this sounds very complex and it seems that you must be an expert But it really is something very simple that we will do in less than a minute Decompress Xamarin NET LibrariesIf you don t have Python on your machine install it previously Once we have Python I run it from the VSCode terminal we proceed Install lz python m pip install lz or simply pip install lz Use of the decompression scriptimport lz blockimport sysimport structimport osdef print usage and exit sys

endswith dll decompress file n except print failed to decompress os path basename file print nDecompressed n assemblies The author of this script is Christian Reitter X D Sec GmbH thank you for your article at X D Sec GmbH we have modified it to unzip all the files in the directory We will copy the code into a file called decompress py and we will save it in the same path as our dll files Decompress the files we need We will do it with py decompressor py we ll let it decompress all the dll files in the directory In this case I am only interested in the two files corresponding to my application What has not been so difficult Now we have the files ready to open with DnSpy Now again we can do everything I mentioned earlier the procedure is always the same only the way in which the files are compiled varies This applies to all applications under NET such as games developed in Unity with C virtual reality applications and augmented reality Did you like this article It has been very simple but I consider it fine for a basic level and learn a little about these topics If you have found it interesting do not hesitate to support it and tell us below if you want to know something else like let s talk about cracking injection and other aspects We could do some interesting practices or whatever you want to see around here Thank you for reading the article and remember that in dotnetsafer we will be uploading articles about security in relation to NET You have the web version of Dnspy at so that you can comfortably do all the tests in this article without having to download any program Thank you for your attention we hope you have learned a lot	2022-01-20 15:55:29

MSK)	https://dev.to/aws-builders/introduction-to-amazon-managed-streaming-for-apache-kafka-amazon-msk-3fpe	Introduction to Amazon Managed Streaming for Apache Kafka Amazon MSK IntroductionAmazon MSK is a fully managed service that makes it easy for you to build and run applications that use Apache Kafka to process streaming data Apache Kafka is an open source platform for building real time streaming data pipelines and applications With Amazon MSK you can use native Apache Kafka APIs to populate data lakes stream changes to and from databases and power machine learning and analytics applications Big Data Analytics Options on AWS is a Series containing different articles that provides a basic introduction to different Big Data Analytics Options on AWS Each article covers the detailed guide on how each service is used for collecting processing storing and analyzing big data Apache Kafka clusters are challenging to set up scale and manage in production When you run Apache Kafka on your own you need to provision servers configure Apache Kafka manually replace servers when they fail orchestrate server patches and upgrades architect the cluster for high availability ensure data is durably stored and secured set up monitoring and alarms and carefully plan scaling events to support load changes Amazon MSK makes it easy for you to build and run production applications on Apache Kafka without needing Apache Kafka infrastructure management expertise With a few clicks in the Amazon MSK console sign in required you can create a fully managed Apache Kafka cluster that follows Apache Kafka s deployment best practices or you can create your own cluster using your own custom configuration After you create your desired configuration Amazon MSK automatically provisions configures and manages the operations of your Apache Kafka cluster and Apache ZooKeeper nodes An Amazon MSK cluster is the primary Amazon MSK resource that you can create in your account Following are the primary components that work together in MSK Broker nodes ーWhen creating an Amazon MSK cluster you specify how many broker nodes you want Amazon MSK to create in each Availability Zone Each Availability Zone has its own virtual private cloud VPC subnet ZooKeeper nodes ーAmazon MSK also creates the Apache ZooKeeper nodes for you Apache ZooKeeper is an open source server that enables highly reliable distributed coordination Producers consumers and topic creators ーAmazon MSK enables you to use Apache Kafka data plane operations to create topics and to produce and consume data Cluster operations ーYou can use the AWS Management Console the AWS Command Line Interface AWS CLI or the APIs in the SDK to perform control plane operations For example you can create or delete an Amazon MSK cluster list all the clusters in an account view the properties of a cluster and update the number and type of brokers in a cluster Amazon MSK detects and automatically recovers from the most common failure scenarios for clusters so that your producer and consumer applications can continue their write and read operations with minimal impact When Amazon MSK detects a broker failure it mitigates the failure or replaces the unhealthy or unreachable broker with a new one In addition where possible it reuses the storage from the older broker to reduce the data that Apache Kafka needs to replicate Your availability impact is limited to the time required for Amazon MSK to complete the detection and recovery After a recovery your producer and consumer apps can continue to communicate with the same broker IP addresses that they used before the failure Ideal usage patternsThe AWS Streaming Data Solution for Amazon MSK enables you to capture store process and deliver real time streaming data This service helps you address real time streaming use cases for example Capture high volume application log filesAnalyze website clickstreamsProcess database event streamsTrack financial transactionsAggregate social media feedsCollect IT log filesContinuously deliver to a data lake Cost modelAmazon MSK has a simple “pay only for what you use model There are no minimum fees or upfront commitments There are charges for the time your broker instances run the storage used monthly and standard data transfer fees for data in and out of the cluster Apache Kafka broker instance usage is billed on an hourly basis billed at one second resolution with varying fees depending on the size of the Apache Kafka broker instance and active brokers in your Amazon MSK clusters Amazon MSK charges for the amount of storage you provision in the cluster This is calculated by adding up the GB per broker each hour and dividing by the number of hours in the month resulting in a value in GB Month There are no additional charges for data transfer between brokers or between Apache ZooKeeper nodes and brokers Standard AWS data transfer charges are charged for data transferred in and out of Amazon MSK clusters See Amazon MSK pricing for further details PerformanceAmazon MSK allows you to choose the right type and number of brokers for yourcluster You can size your cluster based on your ingestion rate hours of retention and data output rates The number of partitions per broker is affected by use case and configuration To determine the right number of brokers for your MSK cluster and understand costs see the MSK Sizing and Pricing spreadsheet file download For more information about the different broker types see Broker types Durability and availabilityUse the following recommendations so that your MSK cluster can be highly available during an update such as when you re updating the broker type or Apache Kafka version for example or when Amazon MSK is replacing a broker Ensure that the replication factor RF is at least two for two AZ clusters and at least three for three AZ clusters An RF of one can lead to offline partitions during a rolling update Set minimum in sync replicas minISR to at most RF A minISR that is equal to the RF can prevent producing to the cluster during a rolling update A minISR of two allows three way replicated topics to be available when one replica is offline Ensure client connection strings include multiple brokers Having multiple brokers in a client s connection string allows for failover when a specific broker is offline for an update Scalability and elasticityYou can increase the capacity of the cluster at any time according to your business or operational needs You can use Amazon MSK operation to increase the number of brokers in your MSK cluster To expand a cluster make sure that it is in the ACTIVE state You can also increase storage per broker You can increase the amount of EBS storage per broker but you can t decrease the storage Storage volumes remain available during this scaling up operation You can use Automatic scaling ーYou can configure Amazon Managed Streaming for Apache Kafka to automatically expand your cluster s storage in response to increased usage using Application Auto Scaling policies Your automatic scaling policy sets the target disk utilization and the maximum scaling capacity Manual scaling ーTo increase storage wait for the cluster to be in the ACTIVE state Storage scaling has a cooldown period of at least six hours between events Even though the operation makes additional storage available right away the service performs optimizations on your cluster that can take up to hours or more The duration of these optimizations is proportional to your storage size InterfacesAmazon MSK has deep AWS service integrations with Amazon EMR AWS Lambda Amazon Kinesis Data Analytics and AWS Glue Streaming ETL It also works with Kafka Connect Mirror Maker Kafka Streams and a number of rd party frameworks like Apache Spark Apache Storm and so on The producer side APIs add messages to the cluster for a topic The consumer side APIs get messages for a topic as a stream of messages Anti patternsAmazon MSK has the following anti patterns Ad hoc queries ーMSK is a stream of unbounded data It is not used for ad hoc queries Long term data storage and analytics ーMSK is not suited for long term data storage Hope this guide gives you an Introduction to Amazon Managed Streaming for Apache Kafka Amazon MSK Let me know your thoughts in the comment

海外TECH	DEV Community	Spring Boot REST API authentication best practices using JWT (2022)	https://dev.to/prafful/spring-boot-rest-api-authentication-best-practices-using-jwt-2022-3j2d	Spring Boot REST API authentication best practices using JWT OverviewIn this tutorial I will explain how you can implement production ready token based REST API authentication using JWT JSON Web Tokens Further we will use these tokens to identify our acting user in a HTTP request to our API For this tutorial we will use MongoDB to persist our user data you can choose any database of your choice What is a JWT JSON Web Token JWT is an encoded string which we will use to identify our user in this case A JWT consist of three parts separated by a period Header It contains signing algorithm like SHA Payload It contains our user data Signature To verify the message wasn t changed along the way making it secure Combing all three will make our JWT look something like this xxxxx yyyyy zzzzz To learn more about JWT please visit Project InitializationWe will start y initializing our Spring Boot project using Spring Initiailizr For starters I have added dependencies you can tweak it a little according to your project needs Hit generate and import project in your favorite IDE Also don t forget to add database properties in application properties file spring data mongodb database your db name herespring data mongodb port Additional DependenciesYou will have to add following dependencies in order to use JWT in your project commons lang is optional I personally use it for its various utility classes For maven based projects lt dependency gt lt groupId gt io jsonwebtoken lt groupId gt lt artifactId gt jjwt api lt artifactId gt lt version gt lt version gt lt dependency gt lt dependency gt lt groupId gt

jjwt impl io jsonwebtoken jjwt jackson org apache commons commons lang Project StructureWe will follow MVC pattern please refer to following project structure ConfigurationIn WebSecurityConfig java we will modify default spring security features by extending WebSecurityConfigurerAdapter class Here we will define our HTTP request filter and a default response when the user is unauthenticated It will act as a middleware for all our HTTP requests package com example api config import com example api util JwtRequestFilter import com fasterxml jackson databind ObjectMapper import org springframework

httpSecurity method we have defined to permit all request starting with auth route that s where we will add our Authentication Controller If the request is unauthorized our API will throw a error message Request FilterIn JwtRequestFilter java we will define our request filter which we mentioned in our API middleware in previous chapter For this we will extend OncePerRequestFilter Spring guarantees that it is executed only once for a given request In this doFilterInternal method we will fetch JWT token from the request header and process it by validating and obtaining username from token s payload Further if token is valid we will fetch user from database and add it in SecurityContextHolder we can further use it any of our service to perform various user related operations

Now its time to actually use our JWT token to identify user associated to a HTTP request Following code snippet will help you get the authenticated user anywhere in your project Authentication authentication SecurityContextHolder getContext getAuthentication String username authentication getName For testing we will define UserController java Here you can get the user we added earlier during request filter in SecurityContextHolder package com example api controller import org springframework security core Authentication import org springframework security core context

海外TECH	DEV Community	Getting the follower count from Twitter API v2	https://dev.to/twitterdev/getting-the-follower-count-from-twitter-api-v2-4jh6	Getting the follower count from Twitter API vVersion of the Twitter API has been the primary way to access the developer platform since November but with around years of blog tutorials about v there is a lot less information shared by the developer community about the new version Let s start to change that Here s a great question I just answered in the Twitter tag on Stack Overflow How do I find the number of followers for a Twitter user in API v You can see the full question and my answer embedded below I thought I d post here in order to expand on my response a little Jan Comments Answers I am surprised to see that there is no way to simply get the number of followers for one Twitter account I found many answers Follower count number in Twitter How to obtain follower count in Twitter API How to get followers count from twitter… Open Full Question The answer is quite simple but not everyone is familiar with the new data formats yet In v we have reduced the number of fields returned by default and you can opt to select the information that is useful for your application using the fields and expansions parameters The follower and following counts for a user are part of the public metrics fields in the User object The API endpoint and parameters are in the format ID user fields public metrics any other fields Below is an example of the output using the twurl command line tool I wrote a post about twurl here In this case twurl handles the authentication etc but you could also use the Twitter API v Postman Collection or the API Explorer from the API Tools available on the developer website or a library of your choice twurl j users user fields public metrics created at data id username andypiper created at T Z name andypiper xyz public metrics followers count following count tweet count listed count In this call we ve requested user ID which is me give me a follow if you feel like it By default without any parameters calls to the users lookup endpoint only return the id name and username values Here we added the user fields to also ask for the public metrics followers following number of Tweets I ve posted and the number of lists the account has been added to So the answer to the original question to get the follower count ask for the public metrics field in the User object and access data public metrics followers count in the response Let s take it one step further Expansions and fields are powerful Using an expansion we can also ask for my current pinned Tweet and more details about the contents of that Tweet in a single API call twurl j users user fields public metrics created at pinned tweet id amp expansions pinned tweet id amp tweet fields created at public metrics source context annotations entities data public metrics followers count following count tweet count listed count pinned tweet id id username andypiper created at T Z name andypiper xyz includes tweets public metrics retweet count reply count like count quote count entities urls start end url expanded url display url dev to andypiper what… images url name orig width height url name x width height status title What resources help you to learn a new API description In my day job when I m not learning things by reading and sharing here on DEV I m a developer unwound url annotations start end probability type Product normalized text Twitter text I d love to know more about how you learn to use new APIs and how I can help you to learn about Twitter API v id source Twitter Web App context annotations domain id name Brand Category description Categories within Brand Verticals that narrow down the scope of Brands entity id name Services domain id name Brand description Brands and Companies entity id name Twitter created at T Z OK that s a lot more information Let s break it down Here I did the following added the user field to request pinned tweet id which returned pinned tweet id also I asked for this to be expanded in the response expansions pinned tweet id That gets expanded inside of the includes array in the response by default the API only returns the id and text fields for a Tweet object so I also specified that I wanted more information I asked for tweet fields and specified created at public metrics source context annotations and entitiescreated at creation time of the Tweet the UTC time when I posted it public metrics similar to metrics on the User object we get data about the numbers of retweets replies likes and quotes of this Tweet source the name of the App that was used to post the Tweet the Twitter website in this case context annotations OK this is super cool We get back an array of information domain entity pairs that cover what Twitter has detected this Tweet to be about In this case I was posting about the Twitter API so it pulled out that I m talking about a brand and company Twitter in the Tweet There are also domains and entities for things like movies sports products award shows and so on You can even search for Tweets by entity value using the v API very powerful entities this is also an improvement additional set of data over v The entities identified in my original Tweet are broken out and expanded In this case there was a shortened URL to a blog post here on DEV This is expanded to show the full URL and what is displayed in the Tweet as well as the URL to the image that is displayed in the website summary large image card and the dimensions of that image and the description from that card Read more about the new Twitter data formats and Tweet payloads on the Developer Blog Talk to us via the Twitter Developer Community forums Share what you learn about Twitter API v here on DEV Use the twitter tag It will help others to learn too Finally if you found this interesting or helpful I d love to hear from you in

海外TECH	Engadget	Oura’s third-generation Ring is more powerful, but not for everybody	https://www.engadget.com/oura-ring-version-3-150032257.html?src=rss	Oura s third generation Ring is more powerful but not for everybodyThe wearables business is hard especially if you re a small startup with a device you could perhaps uncharitably call “niche Oura which makes activity tracking rings worn endorsed by a numberof celebrities recently released its third generation model This new hardware is a technical marvel packing many of the features that most wrist worn devices take for granted But the need to keep the cash rolling in has seen Oura like Fitbit Apple Wahoo and others pivot to a recurring revenue model Oura says that this is key to shift from the idea of buying a device that never changes to supporting its broader goals of building an evolving fitness ecosystem HardwareDaniel CooperBefore we get into the specifics of this new Oura ring let s take a moment to remember that this device is still a marvel of engineering Taking the sensors from a smartwatch or fitness tracker and shrinking them into a ring is worthy of enormous praise For all of its imperfections it s amazing to see Oura push the limits of what is capable in such a small form factor And there s much more tech crammed in this time around despite the size and weight remaining the same as the second generation version The headline features these new sensors enable include continuous heart rate tracking temperature monitoring blood oxygenation and period prediction The sizing process is the same for pretty much every smart ring I ve ever tried The company sends you a set of plastic dummy rings you have to wear for a couple of days Once you ve determined the correct fit which is tight and secure around the base of your index finger but not to the point where it s uncomfortable you can order the real thing This actually was the most stressful part of this review since I felt that one size was too loose the other too tight but I opted for looseness rather than sacrificing a digit to the gods of fitness tracking Oura says that the index finger is the best place for its ring but you can stick it elsewhere if you prefer Unfortunately the one thing you can t do much about is the size of the ring itself which is a bit too big I m a big ish guy with big ish hands but it feels a bit too ostentatious on my fingers enough that people notice and ask me what it is as soon as they spot it If you have more slender hands I m sure you might have a similar issue with folks pointing it out I suspect that the smart thing to do is visit Parts Of to get some more adornments to balance out the look SoftwareWithout a screen Oura is yoked tightly to the iOS or Android app where all of this data will be displayed The Oura app is clean and tidy only giving you the deepest data when you go looking for it The app breaks down all of the information generated from your finger and compresses it into three scores which are shown on the homescreen These are for Readiness Sleep and Activity representing how prepared you are to face the day how well rested you are and how much exercise you re doing The only other thing you ll find on the homescreen is a breakdown of your heart rate across the day showing you where the peaks and troughs are You ll also get advice on your ideal bedtime which is useful when you re working late nights and need to juggle sleep with getting things done You ll also get periodic reminders to move if the app detects you ve been still for a while and advice when it s time for you to wind down for the day Go into one of the categories like Readiness and you ll get scores for your recovery index sleep as well as your HRV balance body temperature and resting heart rate You can also see that my figures dropped quite substantially during a three day period when I got food poisoning from a New Year s Eve takeaway meal During that period I was given plenty of warnings telling me I wasn t rested or well enough to do much else not that I felt like I was gonna go for a run or anything As part of Oura s plan to add extra value to its platform the company is adding a series of video and audio guides for meditation breathwork and sleeping These guides which are essentially guided meditation audio tracks can be backed with a white noise option of your choice You can pick the hum of a train station the crunch of a forest stroll the sound of the tide lapping at the land or rainfall amongst others These are a thing for people who find those things useful to fall asleep and feel restful but I personally do not find them that great That said where Oura differs from its rivals in this space is that it ll break down your vital signs during your meditation If you re wondering how to get better at meditating then you ll be guided to more appropriate tracks that ll help prod you toward nirvana Oura is working on adding more features to the Ring v over the next year including more content as well as more accurate sleep and period tracking These will not actually appear as new features so much as they are behind the scenes improvements in the underlying systems Finally at some point this year the ring will be able to identify your blood oxygenation SpO while you sleep in order to help detect disorders like sleep apnea In useDaniel CooperThe best thing about the Oura ring is that once you ve worn it a few days you quickly start to ignore its presence And while you re not paying attention it begins worming its way into every corner of your life learning your working patterns and getting ready to make helpful suggestions If you feel like crap in the morning but don t have the mental wherewithal to comprehend why you ll be told as soon as you look at your phone Don t get me wrong there s nothing here that other platforms don t do as well but this is certainly an elegant implementation of the idea Sleep tracking is generally fine by which I mean it works by tracking movement and therefore can t tell when you ve been rudely awoken but haven t moved As part of this new pivot however Oura is promising that the sleep tracking will soon become vastly more accurate as a consequence of behind the scenes changes This will not be readily visible to users however since all you ll get is a pop up telling you that things just got more accurate Still it offers a fairly good indicator for how the night went although I find the activity tracking to be a little more on the generous side Yesterday morning for instance it told me that my morning shower was a strength training workout with plenty of burned calories for my trouble Similarly it ll tell me around lunchtime that I need to take a half hour brisk walk to finish my activity for the day and then by early evening having done nothing more than stand at my desk make dinner and put my kids to sleep it ll tell me I ve completed my goal One of the features that Oura is tempting its users with is Workout Heart Rate which I find inadvertently amusing Because the ring is so chunky and it has such a hard edge that I really don t find it comfortable to wear during workouts For instance if I ve got a pair of free weights or I m doing an incline push up on a Smith machine bar the ring just pushes into the fleshy parts of my hand For most of the proper “gym workouts I ve done the ring has had to come off lest I tap out too early or draw blood from the chubby parts of my fingers But for more ring friendly jobs like running walking or cycling you should find this to be a big help In terms of vital signs tracking accuracy I think it s always wise to remember that wearables will not be as inch perfect as a clinical grade device But in a number of random spot tests the Oura offered the exact same figures as the Apple Watch on my wrist In fact Oura s reputation for accuracy has always been pretty high and one of the reasons that the company hasn t released some of these features is to ensure they re ready to go when they do arrive Oura quotes battery life at seven days although I rarely managed to get past five without having to drop it on the charging plate Certainly real world stamina is a bit far from what the company is saying but then it s hardly a deal breaker since you can charge it full in two hours It s become common for me to take the ring off while I m standing at my desk on Monday and Friday mornings and let it re juice while I m working EconomicsThe third generation Oura ring will set you back which gets you the ring in one of four finishes Silver Black Stealth or Gold In the box you ll receive the charging plate and a USB C cable and as part of the deal you ll get a six month trial of Oura s subscription service Membership which costs a month for new users will entitle you to “daily health insights “personalized recommendations as well as more video and audio sessions Any existing Oura user who upgrades to the new ring will get a lifetime membership thrown in for free I want to be fair here and say that I understand why Oura is pivoting to this recurring revenue model It s not as if other companies in this space like Fitbit aren t doing the same in the hope of bolstering their bottom lines And that s before we get to talk about how much lock in the Apple Watch gets as a consequence of Fitness But I also think there s a difference between the sort of product that those rivals are offering compared to Oura s product After all Apple and Fitbit can both offer coaching both on their devices and on bigger screens which Oura can t Not to mention that Oura is really only able to offer guided audio clips and short videos through its app And that while Apple and Fitbit are selling their devices as having the potential to become Capital F Fitness gear the Oura really isn t But then again that s not what Oura is pitching here it s for the meditator the runner the cyclist who doesn t want to strap something beefy to their wrist Wrap UpHere s the problem with reviewing Oura It s not a device that every fitness person will love If you want something with more versatility you d buy a smartwatch and have done with it Oura is more of a subtle product for people who want to be less ostentatious about their health or simply want something that slips into their lives and does the job Honestly since I m not a gym bro I really like the data the ring offers me without any fuss or muss As for the subscription it s likely that Oura will have to keep squeezing as many new features and insights as possible out of this new hardware Between that and vastly improving its currently slender content library it s worth it if you re a paid up member of the Oura family But and this is more a comment on the industry as a whole rather than a slight against Oura itself I do find this need for every company to squeeze some rental income out of their users to be a little bit grating	2022-01-20 15:00:32
