海外TECH	DEV Community	How To Use The map() Function In Dart	https://dev.to/bjcarlson42/how-to-use-the-map-function-in-dart-d0g	How To Use The map Function In Dart The ProblemRecently I was building a Flutter app and I needed to map over an array of users when a user logged in and check if their username password and security question answer matched what wasin the database the userArray I tried to do something like this var userArray User User User userArray map user gt if user User log user in else don t log user in Quick note I removed some of my project specific logic and only included the important parts so it is easier to follow This code logs the user in if they are user This looks like it should work right Unfortunately it doesn t It will not break either Instead nothing will happen This makes it hard to debug The SolutionThe simple solution is to add toList to the end of the map statement var userArray User User User userArray map user gt if user User log user in else don t log user in toList add toList here Why This WorksUnlike in JavaScript in Dart when you map over an object the Iterable thatis returned is lazy This means it is not evaluated by calling map To evaluate it we need to call toList Youcan read more about this here If you want to quickly see this in action open up DartPad and paste in the code below with added print statements with and without toList void main var userArray User User User userArray map user gt if user User print logging user in else print Not user can t log in toList Remove toList to see no output From The Flutter Docs map Iterable lt T gt map lt T gt T Function String f Returns a new lazy Iterable with elements that are created by calling f on each element of this Iterable in iteration order This method returns a view of the mapped elements As long as the returned Iterable is not iterated over the supplied function f will not be invoked The transformed elements will not be cached Iterating multiple times over the returned Iterable will invoke the supplied function f multiple times on the same element Methods on the returned iterable are allowed to omit calling f on any element where the result isn t needed For example elementAt may call f only once toList List lt Set lt Set lt void gt gt gt toList bool growable true Creates a List containing the elements of this Iterable The elements are in iteration order The list is fixed length if growable is false	2021-05-01 15:06:47

GCP	Cloud Blog	Cloud computing 101: Frequently asked questions	https://cloud.google.com/blog/topics/inside-google-cloud/cloud-computing-101-frequently-asked-questions/	Cloud computing Frequently asked questionsThere are a number of terms and concepts in cloud computing and not everyone is familiar with all of them To help we ve put together a list of common questions and the meanings of a few of those acronyms You can find all these and many more in our learning resources What are containers Containers are packages of software that contain all of the necessary elements to run in any environment In this way containers virtualize the operating system and run anywhere from a private data center to the public cloud or even on a developer s personal laptop Containerization allows development teams to move fast deploy software efficiently and operate at an unprecedented scale Read more Containers vs VMs What s the difference You might already be familiar with VMs a guest operating system such as Linux or Windows runs on top of a host operating system with access to the underlying hardware Containers are often compared to virtual machines VMs Like virtual machines containers allow you to package your application together with libraries and other dependencies providing isolated environments for running your software services However the similarities end here as containers offer a far more lightweight unit for developers and IT Ops teams to work with carrying a myriad of benefits Containers are much more lightweight than VMs virtualize at the OS level while VMs virtualize at the hardware level and share the OS kernel and use a fraction of the memory VMs require Read more What is Kubernetes With the widespread adoption of containers among organizations Kubernetes the container centric management software has become the de facto standard to deploy and operate containerized applications Google Cloud is the birthplace of Kubernetesーoriginally developed at Google and released as open source in Kubernetes builds on years of running Google s containerized workloads and the valuable contributions from the open source community Inspired by Google s internal cluster management system Borg Kubernetes makes everything associated with deploying and managing your application easier Providing automated container orchestration Kubernetes improves your reliability and reduces the time and resources attributed to daily operations Read more What is microservices architecture Microservices architecture often shortened to microservices refers to an architectural style for developing applications Microservices allow a large application to be separated into smaller independent parts with each part having its own realm of responsibility To serve a single user request a microservices based application can call on many internal microservices to compose its response Containers are a well suited microservices architecture example since they let you focus on developing the services without worrying about the dependencies Modern cloud native applications are usually built as microservices using containers Read more What is ETL ETL stands for extract transform and load and is a traditionally accepted way for organizations to combine data from multiple systems into a single database data store data warehouse or data lake ETL can be used to store legacy data orーas is more typical todayーaggregate data to analyze and drive business decisions Organizations have been using ETL for decades But what s new is that both the sources of data as well as the target databases are now moving to the cloud Additionally we re seeing the emergence of streaming ETL pipelines which are now unified alongside batch pipelinesーthat is pipelines handling continuous streams of data in real time versus data handled in aggregate batches Some enterprises run continuous streaming processes with batch backfill or reprocessing pipelines woven into the mix Read more What is a data lake A data lake is a centralized repository designed to store process and secure large amounts of structured semistructured and unstructured data It can store data in its native format and process any variety of it ignoring size limits Read more What is a data warehouse Data driven companies require robust solutions for managing and analyzing large quantities of data across their organizations These systems must be scalable reliable and secure enough for regulated industries as well as flexible enough to support a wide variety of data types and use cases The requirements go way beyond the capabilities of any traditional database That s where the data warehouse comes in A data warehouse is an enterprise system used for the analysis and reporting of structured and semi structured data from multiple sources such as point of sale transactions marketing automation customer relationship management and more A data warehouse is suited for ad hoc analysis as well custom reporting and can store both current and historical data in one place It is designed to give a long range view of data over time making it a primary component of business intelligence Read more What is streaming analytics Streaming analytics is the processing and analyzing of data records continuously rather than in batches Generally streaming analytics is useful for the types of data sources that send data in small sizes often in kilobytes in a continuous flow as the data is generated Read more What is machine learning ML Today s enterprises are bombarded with data To drive better business decisions they have to make sense of it But the sheer volume coupled with complexity makes data difficult to analyze using traditional tools Building testing iterating and deploying analytical models for identifying patterns and insights in data eats up employees time Then after being deployed such models also have to be monitored and continually adjusted as the market situation or the data itself changes Machine learning is the solution Machine learning allows businesses to enable the data to teach the system how to solve the problem at hand with machine learning algorithmsーand how to get better over time Read more What is natural language processing NLP Natural language processing NLP uses machine learning to reveal the structure and meaning of text With natural language processing applications organizations can analyze text and extract information about people places and events to better understand social media sentiment and customer conversations Read more Learn moreThis is just a sampling of frequently asked questions about cloud computing To learn more visit our resources page at cloud google com learn Related ArticleRead
