海外TECH	DEV Community	Managing the Obscure Boundaries Between Development, QA, and DevOps	https://dev.to/qamadness/managing-the-obscure-boundaries-between-development-qa-and-devops-2m6l	Managing the Obscure Boundaries Between Development QA and DevOpsAs technology has advanced so have the processes with IT organizations DevOps is fast becoming the pinnacle framework for software development companies with the promise increased business agility accelerated product delivery and higher product quality Moving away from the traditional waterfall approach that included labor intensive tasks such as manual software testing DevOps streamlines automates and shortens the development life cycle This has become a necessity in today s increasing competitiveness in the software app market The transition of software practices encompasses more than just process change or the adoption of different tools People sit at the heart of efficient processes and DevOps is built on the foundation of eliminating barriers between roles Modernized Characters in a Modern ProcessThe success of DevOps starts with a refreshed mindset regarding key roles within the software life cycle This involves having the right people with the right skills who are collectively willing to adapt communicate and collaborate This is vastly different from previous business models where development and QA resources would work in silos unaware of each other s roadblocks and often lacked clarity of the business requirements context Every role was distinct as work passed along the assembly line DevOps has transformed philosophies and responsibilities to achieve enhanced velocity DevelopmentBoth past and present processes start with development getting business requirements However in a DevOps environment these requirements are not in lengthy documents with a deadline that is several months in the future as you would find in a waterfall approach Development is planned in user stories with week sprints in which requirements are defined for delivery These requirements provide direction on how to build the software logic in the most efficient and practical way QAQuality assurance engineers keep their focus on software quality and use a combination of automated and manual testing while ensuring adherence to the initial business requirements Traditionally QA received a build from development at which point a series of testing began and could take up to weeks or more to complete Prior to receiving the build for testing QA had little if any interaction with the development stage Today QA is more aligned with development and it gets involved in the process from the beginning QA also embraces more test automation services that involve pre testing and post testing checks to achieve as much code coverage as possible Automation also requires a new skill set and standardization of testing environments DevOpsDevOps is the merging of development and operations which requires a change in both technology and culture Oftentimes organizations create DevOps as an aside to development and operations which defeats the purpose Companies must be prudent with the adoption of DevOps because new roles labels and titles don t necessarily bring about real change The DevOps methodology integrates the functions of software development and operations within the same cycle The goal is to improve collaboration across teams and deliver better experiences internally and to the end customer To achieve this a high level of collaboration is needed between the major stakeholders in the software development process being dev QA and operations How do Development and Quality Assurance fit in DevOps In DevOps developers and QA both play equally important roles In fact every actor in the process is responsible for the timeliness and quality of deliverables This makes the boundaries of roles porous While titles such as developer and QA are the same their scope in roles has increased From the outset of defining requirements test cases are created at the development and QA level The Developer s Role in DevOpsDevelopment now has a greater emphasis on automating the testing build and deployment tasks and a more intimate knowledge of the continuous integration cycle And it requires a more forward thinking attitude where developers need to consider dependencies and environments that go beyond the individual s pc Gone are the days of using the old excuse of “well it works on my machine After building the code and doing initial tests developers then promote the code package to the next environment which is typically the testing environment For developers it is no longer just creating code from requirements They need to encapsulate testing methods and provide continuous monitoring as well Engagement with testing is more extensive than before which has been a catalyst for incorporating automated testing Having developers think like testers is an added step in ensuring better product quality The QA Role in DevOpsDevOps QA has transitioned to a more strategic role in helping a team build robust software As the developers roles and mindset has changed so has that of DevOps QA engineer They need to be able to test an application using a range of tools while also being capable of fixing code Although not every aspect of testing can be automated it s not practical to stick to manual testing and still be agile Automation is crucial for everyday testing and for automating regression testing And if QA struggles to adopt this change the quality of the product will degrade and bottlenecks will accumulate in the software life cycle A QA strategy using best practices is highly relevant and key to achieving superior product quality What Are the Benefits and Difficulties in DevOps Management When implemented and adopted efficiently considerable benefits can be achieved with DevOps However it is not a silver bullet for every organization and every team It doesn t come without its challenges Here are notable advantages as well as the difficulties that come managing an effective DevOps process BenefitsProduct quality is much higher with test cases defined early on and testing points added in the development process Additionally automation constantly checks new code hasn t impacted core functionality or broken core dependencies Product stability allows teams to spend less time on support and security issues A perpetual cycle of ongoing bugs and fixes is frustrating for dev and QA as well as the customer Stability means that the DevOps team can spend more time on developing new features and skilling up on new technologies Enhanced expertise means the product improves and staff turnover remains low Deployment speed increases so developers are able to deploy updates or new features more regularly as opposed to developing enhancements once a month or twice a year If all the above are realized throughout the process the customer satisfaction rate increases with having a stable feature rich app ChallengesHaving a control and command leadership style doesn t fit in well with a true DevOps environment It relies on more than one mind to solve create and deliver Teams are connected and should encourage innovation and inspiration while creating a space where people feel safe to share thoughts and engage in creating solutions Poor product management strategy can hinder speed reliability and consistency This would be the antithesis of what DevOps is about as it s meant to give companies the competitive edge with great software delivery A solid strategy involves planning out new features knowing the customers needs as well as the competitive landscape It is important to reduce risk while maximizing results Poor design and development can make or break efforts There have been significant changes in software engineering and it s important to stay abreast of these changes Examples include having an updated technology stack moving away from monolithic architectures and exploring and utilizing microservices Managing outdated and cumbersome software doesn t lend itself well to a DevOps environment Tips for Efficient ManagementTo be successful in DevOps you need a good foundation to keep all parts of the process moving while having transparency across the environment Some useful tips can help key players ensure efficiency in managing the DevOps process Focus on communication Having a pool of resources working in a fast and adaptable environment needs proper communication and visibility of all moving parts Never underestimate the importance of testing Testing across different environments and configurations is critical to product stability Size does matter Small cycles small projects and small teams foster agility trust and operational efficiency Stay realistic but relevant While it may be tempting to throw too much at a DevOps process too quickly it can backfire Strive for constant improvement but make sure there is sufficient time without putting unnecessary pressure and expectations on the team ConclusionDevOps is the future of software development companies It brings teams together to support each other Roles overlap but it allows for the creation of multidisciplinary teams while nurturing the talent of high performers When DevOps works well it works great People at all levels of the company benefit when everyone can deliver the best results to the customer DevOps is a journey and the benefits are not realized overnight Knowing that teams can be multiskilled allows for a shared understanding and increased collaboration and innovation DevOps and the roles within highlight it s an environment of continuous improvement for people and product	2021-12-13

海外TECH	DEV Community	Understanding the basics of Story Grooming	https://dev.to/rebecca/understanding-the-basics-of-story-grooming-4c79	Understanding the basics of Story Grooming What is Agile Backlog Grooming Backlog grooming is an agile product team event to make sure that the backlog is sufficient In essence the product team ensures that there are enough user stories in the product backlog which are prepared for spring planning Backlog grooming is also known as backlog refinement or backlog management or story grooming or story time These events or sessions are recurring in nature Having backlog grooming sessions regularly helps to make sure that the team prioritizes the right stories This way the team has a good grasp over the complete product backlog In these backlog refinement sessions the product owners or managers explain the purpose of the prioritized stories to the team The team is then in a position to be better aligned about the project purpose The things that the backlog grooming session tries to achieve are as follows Refining the leftover user stories and removing the ones which are no longer relevant Adding new stories based on the needs that are newly discovered Breaking bigger items into smaller easier tasks orsplitting user stories Prioritizing the ones which are to be tackled first Discuss the user stories with the team and answer any questions which arise so that there are no doubtsAdd contextual info and acceptance criteria to the upcoming user storiesOccasionally the scrum master estimates the user stories and assigns story points in these sessions Corrections to the existing estimates based on the new info available All these items together work in shaping up the tasks and objectives for the next session The key team stakeholders attend these backlog grooming sessions To keep the sessions running well too many people aren t a part of the meetings However all the important stakeholders are supposed to be a part of it These include the core team representatives product managers owners and QA among others Origins of Story GroomingNow that you know what Story grooming is let s understand how the practice came into being The earliest known use of the term backlog grooming was on a Yahoo group in In that year Mike Cohn one of the well known contributors of the scrum world spoke of it on Yahoo Specifically this happened in the Yahoo Group Scrum Development Mailing List However at this time the term wasn t well defined and didn t come into use A few years later in Kane Mar a scrum trainer gave one of the first formal descriptions of the term He called it story time and recommended that these should be implemented as regular meetings in Scrum teams Three years after this in Backlog grooming became a part of the Scrum guide Since then it s been recognized as an official element of the agile scrum framework Who is a part of the Story Grooming sessions We ve already mentioned in passing who is a part of these sessions above However let s understand the details here Who leads Backlog Grooming sessions Usually the product owner or product manager facilitates the backlog refinement events It s not limited to them though and the Scrum master a project manager or another member from the team also occasionally leads the events Whoever leads the sessions has to assume the following responsibilities Schedule the meeting and invite the right people also make sure that they attend Ensure that the team doesn t go off topic and is focused on the objectives In case the team is stuck too long on a particular topic then moving the conversation forward Communicating to the team after the session is over about the necessary things Generally these sessions take about minutes to an hour So the lead has to also try to ensure that the meetings don t take too much time They have to try to keep it short and efficient Who attends the Backlog Refinement sessions The story grooming sessions are collaborative discussions For this it is necessary to get inputs from various team members and to look at things from all viewpoints At the same time it s necessary to not overcrowd the meeting and invite only the critical members So on a broad scale these are the roles that attend the backlog grooming sessions The facilitator or the lead as mentioned in the earlier section The product owner and or other representatives of the product team The entire delivery team or key representatives if it s too large QA reps Preparation for efficient Story GroomingThe following is an idea on how to prepare for the agile story grooming sessions and what to include in them Keep the strategic objectives of the project in mindAt any point of the project the ones working on it should keep in mind what the main goals of the project are So even when preparing for the grooming sessions the high level objectives of the project should be kept in mind Everything should then be aligned accordingly Involve the right people in the processWe ve mentioned above who the ideal people in the story grooming process are You need to decide who are the best people to invite if you re the one conducting the meeting Sync up with stakeholdersTalk to internal and external stakeholders at regular intervals to get feedback You do not need to invite them to the grooming sessions but make sure to keep them updated Review work done and metricsSince your team s working style could evolve over time it s good to get an idea of what to keep and what to discard Tracking and reviewing performance metrics helps with this Best practices for Story GroomingThe story grooming sessions aim to have a prioritized set of user stories for the team to work on Agile practitioners usually try to obtain a DEEP product backlog as a

海外TECH	DEV Community	Release 0.4: Final step	https://dev.to/nguyenhung15913/release-04-final-step-3o91	Release Final step OverviewAs I mentioned in my last blog post I finished the Telescope s issue and my PR got accepted So I spend this week only for the second issue IssueI had a hard time finding the design for the leaderboard There were so many templates and also the design should match the whole website in general especially the background of the site This is the current temporary leaderboard they have After hours I came up with a few designs but this one like the most I send the design to Discord but none of the owners replied to me to I just started working on the leaderboard page Their project was a ReactJs project so setting everything up for me was not hard However there were like thousands lines of code and the way they write their code was confusing to me My solution was just finding the right components for the leaderboard and where it was located so that I did not get distracted by something else Luckily after minutes I found that but I had to write a bunch of console log to know where the component was ProgressI started by creating a new branch First thing I did was keeping the elements inside the JS file intact I only added the className so that I could access it from the css file To know if my class were already applied to the elements I added some background color After that I spend some times to understand the React code and how they displayed the data to front end Another issue that just came to me There were the gaps between the tr elements from the design I thought I just needed to add the margin to it But it was not that easy adding margin did work I was really surprised and started to do some research about table element The solution was separating the elements and adding the spacing for it To match the design I needed to add background for each row The reason I named my class like color color was utilizing the index parameter from the map function Also we cannot add the border radius for tr so I needed to add this feature to td instead tr td first child border top left radius px border bottom left radius px tr td last child border top right radius px border bottom right radius px tr th first child border top left radius px border bottom left radius px tr th last child border top right radius px border bottom right radius px I also had to remove some old CSS styling of the owner And this is the final result You will see I modify the Go to Page so it would be neat and more beautiful Also I added a yellow cup from material ui for the top player This will make my design more interesting Note that only the cell that has value will have the cup icon Pull requestAfter that I submitted a PR It did not go smoothly because there were some request changes from the owner He would like me to modify the colors and there was a bug related to displaying If more than players are displayed the rest will be transparent At the moment I am still working on the changes to my PR and I am pretty sure that everything will be good because I know how to handle this problem Last thoughtThis final release was very useful I have learnt a lot of things from understanding a completely new style of writing React code Also I learnt new feature of table elements in CSS and this will be great for me in my future project that would use table	2021-12-13 12:20:57
海外TECH	Engadget	The Morning After: Peloton's unfortunate cameo in the 'Sex and the City' reboot	https://www.engadget.com/the-morning-after-pelotons-unfortunate-cameo-in-the-sex-and-the-city-reboot-121514275.html?src=rss	The Morning After Peloton x s unfortunate cameo in the x Sex and the City x rebootWarning If you re planning to watch the Sex and the City revival And Just Like That avert your eyes for this intro ーspoilers are incoming Peloton probably wished everyone did just that Yes the ubiquitous expensive exercise bike featured in a major plotline in the first episode of the new series which itself isn t particularly shocking The shock came when Carrie s husband Mr Big died of a heart attack after he finished a minute Peloton class on the company s Bike with real instructor Jess King in a fictional role as…a Peloton instructor The plotline hit Peloton s stock price over the weekend ーsomething the company has seen over the last year as many folks head back to their gyms or perhaps like me just nbsp don t want to stay in their homes to exercise anymore Peloton was also caught unawares ーthe company knew HBO would feature a Peloton in the episode and that King would portray an instructor but quot confidentiality reasons quot prevented it from learning it would kill off a character It released a statement saying that Big s death was probably due to his “extravagant lifestyle ーthe guy was smoking a cigar earlier in the episode and had previously suffered a heart attack I doubt the result of Peloton s appearance on the show will be a net negative ーit s arguably the most talked about twist from the premiere of a highly anticipated TV show It s definitely a test of the adage Is any publicity good publicity ーMat SmithNASA s new sleeping bags could prevent eyeball squashing on the ISSIt sucks fluid out of astronaut s heads and toward their feet More than half of NASA astronauts that went to the International Space Station ISS for more than six months have developed vision problems Researchers from UT Southwestern Medical Center have developed a sleeping bag that could prevent or reduce those problems Fluids tend to accumulate in the head when you sleep but on Earth gravity pulls them back down into the body when you get up In the low gravity of space though that fluid collects applying pressure on the eyeball leading to vision impairment The researchers have made a sleeping bag that effectively sucks fluid out of astronauts heads Continue reading
