海外TECH	DEV Community	The EyeDropper API: Pick colors from anywhere on your screen	https://dev.to/polypane/the-eyedropper-api-pick-colors-from-anywhere-on-your-screen-21o2	The EyeDropper API Pick colors from anywhere on your screenWith the new EyeDropper API in Chromium websites can let visitors pick colors from anywhere on their screen adding anotherfeature to the web that used to require hacky solutions and is now just a few lines of code The API isclean and modern and easy to use In this article we ll discuss how to set it up handle edge cases and additional featureswe hope will land in future updates We ve been following the EyeDropper API since it was first proposed and have been experimenting with it as differentparts became available as well as providing input while the feature was being developed In Polypane we started using it extensively for the new color picker and new palettes How to use the EyeDropper APIThe API adds a new global EyeDropper or window EyeDropper that you can use to set up a new eyedropper object const eyeDropper new EyeDropper This eyeDropper object has one function eyeDropper open This starts the color picker and changes the users cursorinto a color picker complete with magnified area and a highlighted pixel This function returns a promise so you canuse it either with await or as a promise One gotcha is that it only works when called from a user initiated event This is part of the security model toprevent websites from potentially scraping pixels without the user knowing Detecting support for the EyeDropper APIBecause the API is only available in Chromium you will need to check for support before using it The most straightforwardway to do that is to only offer your color picking UI when window EyeDropper is not undefined if window EyeDropper Okay to use EyeDropper else Hide the UI await based version won t workconst result await eyeDropper open worksdocument queryselector colorbutton addEventListener click async gt const result await eyeDropper open The eyeDropper open call will resolve in two situations The user clicks anywhere on the screen The user pressed the Esc key In the last situation the eyeDropper will throw an exception but in the first situation you will get a ColorSelectionResultobject which has an sRGBHex property containing the picked color in hexadecimal format In your code you can check ifresult sRGBHex is defined and then do with it what you want document queryselector colorbutton addEventListener click async gt const result await eyeDropper open if result sRGBHex console log result sRGBHex You don t have to handle the exception but if you wanted to provide the user feedback that they cancelled the eyedropper you need to add a try catch to the code document queryselector colorbutton addEventListener click async gt try const result await eyeDropper open if result sRGBHex console log result sRGBHex catch e console log e DOMException The user canceled the selection Promise based versionYou don t have to use the await version eyeDropper open returns a promise so adding a then and catch also works document queryselector colorbutton addEventListener click gt eyeDropper open then result gt console log result sRGBHex catch e gt console log e DOMException The user canceled the selection Things to keep in mind when using the EyeDropper APIThere are two gotchas with the API at least as it s currently implemented in Chromium that we ve found that you shouldbe aware of Color picking does not use the live screenAt least in the current implementation the color picker get the pixels as shown on the screen when you call open This means that if you re playing video the color picker will show the pixels of the frame that was visible then not thelive video This is dependent on the implementation and we hope a future update of Chromium will allow for live data Color picking only works as the result of a user actionAs mentioned earlier you need a user initiated event to open the eye dropper This is to prevent sites from opening theeyedropper UI to start scraping your screen right on load Instead the user needs to perform an action for the API to work like a click or keypress Features we want to see addedThe EyeDropper API is still very young and minimal During our implementation we encountered a number of features that wewould like to see added to the API in future updates Live preview of the hovered colorA major component of many eye droppers like those in design tools is that they also show a preview swatch of thehovered color You can use this to compare it to another swatch or quickly check a HEX code The current API does notoffer this over security concerns We have filed an issue against the EyeDropper API on GitHub for this Live feedback is needed A more extensive color modelCurrently all colors are returned in the sRGB color model This means the API won t accurately return colors outsidethe sRGB spectrum for example those on Apple s P screens How to deal with this is an open issue Work is also happening on a new Color API for the web The EyeDropper API could usethis Color API when it lands in future versions of browsers A more natural way to select multiple colorsBecause of the current security model each time a user picks a color they need to re initiate a user action which can be tedious For example if you want to create a palette of colors in one go you want to start picking colors click on all the colors youwant to add and then close out of the eye dropper We similarly filed an issue for this on Github Do we expect multiselect to work and this feature is currently being considered For this it would be nice if we could designate a part of the page like a button as an area where the EyeDropperdoesn t work that instead functions as a done button This way users can select multiple colors and then click thatbutton when they re done Other browsersFor now the API is only available in Chromium based browsers from version on and there has not been a signal fromSafari and Firefox yet If you want those browsers to support the EyeDropper API as well add your support to the open issues Issue for Firefox and Issue for Safari The EyeDropper API is a nice addition to the browser that we hope to see land in more browsers We make good use of itin Polypane and would like to see it be developed further	2021-11-11

海外TECH	DEV Community	How to concatenate lists in Python?	https://dev.to/hrishikesh1990/how-to-concatenate-lists-in-python-30j5	How to concatenate lists in Python In this tutorial we learn how to use Python to concatenate lists This can be achieved through multiple ways using operators functions and other methods Table of ContentsWhat is Concatenation of Lists Using the operator in Python to concatenate listsUsing the operator in Python to concatenate listsConcatenation of lists using the append methodConcatenation of lists using the extend methodClosing thoughts What is Concatenation of Lists Before we look into what concatenation of lists is let s first look at what a list is in Python A list is one of the most common data structures used not just in Python but in programming in general It is an ordered and mutable Python container To create a list the elements are placed inside square brackets and each element is separated by a comma With that out of the way let us look at the various methods that can be used to check if a list is empty in Python list of integers number list example of a list containing different data typesrandom list “apple ball True Joining two or more lists together in Python is called Concatenation Now let us look at a few methods of concatenating lists in Python Concatenation of lists using the operator in PythonThe asterisk operator is useful for many purposes in programming But one good use for it is using it as an unpacking operator When used as an unpacking operator it “unpacks the contents of a container data structure such as a list into another As one can see in the code below using the asterisk operator makes the code short concise and readable Here is an example of how one can use the operator to concatenate two lists list one and list two Input How to concatenate lists using the operator in Pythonlist one list two list three list one list two print list three Output One can also concatenate more than two lists easily example list list one list two list three In terms of performance the extend method is several times faster than the asterisk operator So the concatenation using the asterisk operator may not be the most efficient method when concatenating large lists Concatenation of lists using the operatorAnother easy way to join lists in Python is to use the operator The operator is an easy to use method of joining two or more lists together in Python Its logic and application is simple and easy to understandWhen we use the operator on two integers we ll get the sum of those integers But when used on lists we get a new list which is the concatenation of those lists Input Python concatenate lists using the operator in Pythonlist one list two answer list one list twoprint “The concatenated list is n str answer Output In this example above by using the operator Python has appended list two at the end of list one and that has resulted in a new list as output The operator however creates a new list for each list concatenation operation This can be a very inefficient manner of using the operator multiple times in a loop Concatenation of lists using append functionAs the name suggests the list zero append x method appends element x to the end of the list zero The append function method is several times quicker in operation compared to the operator It is also readable and easy to use Here is an example of how we can use the append method to concatenate two lists list one and list two and store the result in list one Input How to concatenate lists using the append function in Pythonlist one list two for element in list two list one append element print list one Output A major problem with the append method is that if we want to concatenate two lists we have to iterate over all the elements of the lists and append them one by one This can translate into an extensive process depending on the size of the lists you are dealing with Concatenation of lists using the extend functionHere is yet another function one can use to join lists together The difference between the function append and extend is that the former adds only one element at a time and the latter adds a collection of elements to the list The extend method is also the most concise and fastest way to concatenate lists compared to all other methods Here is an example of how we can use the extend method to join two lists list one and list two together Input How to concatenate lists using the extend function in Pythonlist one list two list one extend list two print list one Output The method list extend iterable adds all the elements in the iterable to the end of the list The extend method which adds all the elements in the iterable to the end of the list is significantly less complicated compared to the append method that iterates through each element and appends them one by one Closing thoughtsApart from the methods seen in this tutorial there are many other ways to concatenate lists in Python Some examples are the concatenation of lists using the List comprehension method and the Concatenation of lists using the itertools chain function However the extend method is said to be the most efficient in terms of performance compared to them all	2021-11-11 13:36:30

trusted authority Amazon QLDB tracks each and every application data change and maintains a complete and verifiable history of changes over time Ledgers are typically used to record a history of economic and financial activity in an organization Many organizations build applications with ledger like functionality because they want to maintain an accurate history of their applications data for example tracking the history of credits and debits in banking transactions verifying the data lineage of an insurance claim or tracing movement of an item in a supply chain network Ledger applications are often implemented using custom audit tables or audit trails created in relational databases However building audit functionality with relational databases is time consuming and prone to human error It requires custom development and since relational databases are not inherently immutable any unintended changes to the data are hard to track and verify Alternatively blockchain frameworks such as Hyperledger Fabric and Ethereum can also be used as a ledger However this adds complexity as you need to set up an entire blockchain network with multiple nodes manage its infrastructure and require the nodes to validate each transaction before it can be added to the ledger Amazon QLDB is a new class of database that eliminates the need to engage in the complex development effort of building your own ledger like applications With QLDB your data s change history is immutable it cannot be altered or deleted and using cryptography you can easily verify that there have been no unintended modifications to your application s data QLDB uses an immutable transactional log known as a journal that tracks each application data change and maintains a complete and verifiable history of changes over time QLDB is easy to use because it provides developers with a familiar SQL like API a flexible document data model and full support for transactions QLDB is also serverless so it automatically scales to support the demands of your application There are no servers to manage and no read or write limits to configure With QLDB you only pay for what you use Amazon TimestreamAmazon Timestream is a fast scalable fully managed time series database service for IoT and operational applications that makes it easy to store and analyze trillions of events per day at th the cost of relational databases Driven by the rise of IoT devices IT systems and smart industrial machines time series data ーdata that measures how things change over time ーis one of the fastest growing data types Time series data has specific characteristics such as typically arriving in time order form data is append only and queries are always over a time interval While relational databases can store this data they are inefficient at processing this data as they lack optimizations such as storing and retrieving data by time intervals Timestream is a purpose built time series database that efficiently stores and processes this data by time intervals With Timestream you can easily store and analyze log data for DevOps sensor data for IoT applications and industrial telemetry data for equipment maintenance As your data grows over time Timestream s adaptive query processing engine understands its location and format making your data simpler and faster to analyze Timestream also automates rollups retention tiering and compression of data so you can manage your data at the lowest possible cost Timestream is serverless so there are no servers to manage It manages time consuming tasks such as server provisioning software patching setup configuration or data retention and tiering freeing you to focus on building your applications Amazon DocumentDB with MongoDB compatibility

with Amazon DocumentDB with MongoDB compatibility AWS Blockchain ServicesAWS Blockchain is the perfect example of fully managed services for using blockchain technology Blockchain on AWS refers to a small yet powerful assortment of offerings that support the enterprise blockchain initiatives of organizations The Amazon Quantum Ledger Database Amazon Managed Blockchain AWS Blockchain Partners and AWS Blockchain Templates are the prominent entries when it comes to discussions about blockchain on AWS Amazon Managed BlockchainAmazon Managed Blockchain is a fully managed service that makes it easy to create and manage scalable blockchain networks using the popular open source frameworks Hyperledger Fabric and Ethereum Blockchain makes it possible to build applications where multiple parties can execute transactions without the need for a trusted central authority Today building a scalable blockchain network with existing technologies is complex to set up and hard to manage To create a blockchain network each network member needs to manually provision hardware install software create and manage certificates for access control and configure networking components Once the blockchain network is running you need to continuously monitor the infrastructure and adapt to changes such as an increase in transaction requests or new members joining or leaving the network ConclusionAWS databases deliver the high availability reliability and security you need for business critical enterprise workloads They support multi region multi primary replication and provide full data oversight with multiple levels of security including network isolation and end to end encryption More customers trust AWS for their blockchain and ledger technology workloads than any other cloud vendor AWS has over validated blockchain solutions from partners who provide support to all major blockchain protocols including Hyperledger Sawtooth Corda DAML Ethereum and many more Hope this guide helps you with
