海外TECH	DEV Community	How To Make Your First Contribution As a Beginner In Open Source	https://dev.to/shatakshiigupta/how-to-make-your-first-contribution-as-a-beginner-in-open-source-5hkf	How To Make Your First Contribution As a Beginner In Open SourceOpen Source is very powerful that is encouraging and empowering but students today are not really aware of what power the Open Source world really holds how motivating the community is and what opportunities it brings as most of the students do not know much about Open Source and how engaging the community is If you are here then Kudos to you for making your first step into the amazing Open Source world Now with no more delays let s get right into what Open Source really is how inspiring the community is what all opportunities it brings to students and how you also can make a little change to the community and empower others too What is Open Source Open Source when you think of this term what might come to your mind is anything that is freely available well that s what it exactly is Open Source can be explained as source code of any software that you might be currently using or will be using in the near future as the Open Source thing is only going to grow more and more and which is made available to everyone so that every single one of us can have a look help making it better if we think that particular software is missing this feature and if we add that feature to it then the software would become much more better than before So I hope you got a little idea of how things work in Open Source world Some of the most commonly used open source softwares are Mozilla Firefox VLC Media player Image editing tool Gimp and the list is simply endless As now we have known so much about open source let s get right into how you can help make a change and make your first contribution If you know about Open Source I believe that you might be aware of GitHub to but if do not let s know a bit about Git and GitHub to What is Git Git is a version control system that lets you manage and keep track of your source code history What is GitHub GitHub is a web based Git version control repository hosting service GitHub provides all the functionalities of Git along with some of its own features as well Now we will be covering some steps so that you can download Git on your system and get started to contributing to your first repository We will be downloading Git bash through Git bash you will be able to type Git commands that make source code management easier through versioning and commit history Step Download Git on your system from here Step After downloading you need install it on your system So for installation click on run then click on next after that do not change the Destination location and simply click on next after that while selecting components check the boxes with In the Quick Launch and On the desktop After that keep on clicking next Step After installation uncheck the box with View release notes and check the one with Launch Git bash Getting startedTo get involved with Open source projects you need to have a basic understanding of how git commands work and how one has to use those commands to make a valuable contribution Reference for git commands git commands for beginnersQuick reference for git command lines by SimplilearnBasic git commands Contributing Choose a project that interests youThis is the most crucial and salient part of your contribution You need to find a project that interests you and that matches your skillset And this need not to be a very large contribution For someone who is just starting with open source it is highly recommended to start with Fixing typos modifying documentation files in large and even small projects Well as of now if you are reading this you might be looking to contribute as a beginner first contributions can prove to be a really good start for you Hacktoberfest practice and awesome for beginners can really help you as well Finding a projectYou can filter the issues tab according to your skillset let s suppose you have basic knowledge of Java and you want to contribute to projects written in Java language then you can search good first issues by going to the issues tab and searching the issues with labels like label good first issue and language Java In a similar manner you can filter issues by replacing good first issues with first timers only beginner good first bug and easy Forking the projectFork will create a copy of the repository in your GitHub account so that you can make changes to the project Cloning the projectGo to your own GitHub account and there you will see a forked version of that project under your account Now click into this repository that is forked and and we will make a copy of it on your machine by hitting the code button Copy the HTTPS URL Open your terminal or git bash window Move to the location on your computer where you want to create a copy of this project Run the following command git clone Substitute your GitHub username for userid You now have a local copy on your computer The folder on your computer will have the same name as the remote repository on Github Create a new branch named by running the following command git checkout b add your namecd into first contributions Then cd into Contributors Now open the Contributors file in your Text editor Add your name alphabetically into the file along with your GitHub profile URL Now run git status in the terminalYou should see this Changes that you made need to be staged and committed So to add your changes run the following git add Now your changes have been added and you are needed to commit your changes and push it to your remote repository that is on your GitHub account To commit your changes run the following git commit m add your name to contributors listIt is always important to write a good commit message while working in large codebase projects So there you have to take care of writing an explainable and not too long message that describes what your contribution fixes and which can be easily understood by the maintainers of the project Now you have to push your changes to your remote repository so run the following command git push origin branch nameWhen you will head over to your GitHub account you will be able to see a message with compare and pull request button Click on the button and now you will be creating a pull request that will be visible to maintainers of the project After that click on create pull requestYay You just created your first pull request Thanks for following along You are awesome and I am so proud of you NOTE While contributing to any large codebase project or even smaller you can always ask your doubts in Slack channels mailing lists that are there to help you Open Source community is really encouraging and inspiring and inclusive so if you ever feel overwhelmed about such large projects that you want to contribute to you can always ask your doubts and queries in mailing lists and slack channels Remember do not give up ever people in different groups are more than happy to help solve your queries and all you got to do is reach out to them and explain your query If you have followed along then Congratulations on starting your Open Source journey because that is really awesome and I really appreciate your efforts Also mentioning some other resources that will help you in your Open Source programming journey and the amazing Computer Science Field Code for CauseMy Code Schooltake U forwardLove BabbarHope you found this helpful If you did then do share this with people who are beginners like you and want to make their first contribution in Open source Thanks for reading and hope you have a great day Say Hello

GCP	Cloud Blog	3x Dataflow Throughput with Auto Sharding for BigQuery	https://cloud.google.com/blog/products/data-analytics/3x-dataflow-throughput-auto-sharding-bigquery/	x Dataflow Throughput with Auto Sharding for BigQueryMany of you rely on Dataflow to build and operate mission critical streaming analytics pipelines A key goal for us the Dataflow team is to make the technology work for users rather than the other way around Autotuning as a fundamental value proposition Dataflow offers is a key part of making that goal a reality it helps you focus on your use cases by eliminating the cost and burden of having to constantly tune and re tune your applications as circumstances change Dataflow already includes many autotuning capabilities and we are excited to announce a new capability today that further simplifies streaming data pipelines Google BigQuery is one of the most common storage systems that Dataflow Streaming pipelines export results to The Beam SDKs include built in transforms known as BigQuery I O connector that can read data from and write data to BigQuery tables While the write transform has been optimized to take advantage of various BigQuery capabilities e g dynamic destinations currently Dataflow relies on users to manually configure numFileShards or numStreamingKeys to parallelize BigQuery writes This is painful for customers because it is extremely challenging to get the configuration right and requires a lot of manual efforts to maintain it Current ChallengesManually selecting an optimal number of shards is a very hard problem and results in following issues Too low a sharding value leads to insufficient execution parallelism and therefore limited throughput Too high a sharding value leads to increased overhead both on the Dataflow side and BigQuery side which risks diminishing returns In some cases pipeline throughput drops further if it exceeds BigQuery quotas and limits due to high sharding The fundamental issue here is that one size does not fit all Sharding for one shape of the data may not be the right choice when circumstances change e g when the volume changes or when there are “hot spots with much more volume than the others  The following illustration shows what happens with manual fixed sharding when streaming data to a BigQuery table As you can see irrespective of the volume of data the number of shards remains constant and becomes insufficient when the input rate bumps As a result of this configuration the throughput remains constant over time irrespective of the changing volume of data Adding more worker nodes than the shards could hardly be helpful in this case Introducing Auto Sharding for BigQueryIn order to eliminate the painful hand tuning of parallelism for the BigQuery sink we are introducing a new capability Auto Sharding to Dataflow Streaming Engine  With Auto Sharding Dataflow dynamically adjusts the number of shards for BigQuery writes and balances the load to keep up with the input rate The following illustration shows how sharding changes over time in response to changing input data volume BenefitsTo determine the extent of the benefit we ran load tests to compare the performance of BigQuery I O connector with and without Auto Sharding To get a comprehensive understanding of the performance benefits we compared the throughput for worker counts ranging from to As you can see in the following charts Auto Sharding outperformed manual and fixed sharding with BigQuery streaming inserts It boosted the throughput by x to x in most cases without any other changes In general increase in throughput per worker has the potential to reduce the number of workers needed and thereby cost  The difference in throughput increases as the number of workers is increased This is particularly important since it becomes very challenging to hand pick sharding configuration as the scale of your pipeline grows in order to handle increased input volume   Streaming Auto Sharding also works with BigQuery batch loading of data and yields similar improvements to increase in throughput How to enable Auto Sharding for BigQuery SinksYou can enable Auto Sharding in Streaming Engine by setting a new option when configuring the BigQuery I O connector in your code The option is available in both streaming inserts and file loads modes starting Beam for Java and Beam for Python Alternatively you can opt in Auto Sharding for streaming inserts using Beam Java SDK with an additional Dataflow experiment experiments enable streaming auto sharding  The following are code samples to enable Auto Sharding Java Python With the new option the sharding for the BigQuery writes will be automatically determined at runtime to make the best use of workers available If autoscaling is turned on sharding will be adjusted to keep all workers busy when the number of workers changes While the number of shards is not explicitly exposed the changes in sharding is reflected in job metrics such as data freshness and throughput For example increased system latency triggers more workers which in turn increases the number of shards As a result throughput increases and the backlog is cleared faster You can use the Dataflow Console to monitor the number of workers and the throughput of the BigQuery write stage To get started please refer to the documentation for the BigQuery IO Connector and the introduction page to learn more about different ways of data ingestion to BigQuery and how to choose one that fits your needs	2021-05-25 08:00:00
