海外TECH	DEV Community	Breaking the Barrier: The Science of Selling to Developers	https://dev.to/codingnninja/breaking-the-barrier-the-science-of-selling-to-developers-431n	Breaking the Barrier The Science of Selling to DevelopersYes selling to developers is a barrier and so we keep telling one another Don t sell to developers Have you ever asked yourself why is it hard to sell to us Are we not human beings like every other person In this article I will show you why it is hard to sell developers but wait this article is a part of DevRel How to sell to developers check it out to learn more Why is it hard to sell to developers Selling to developers is very hard for four major reasons openness reliability stubbornness and curiosity all of which revolve around the practicality of software development Developers are the best among the smart they are very open and highly curious At first these reasons may seem odd but you will realize the truth in them soon Listen salespeople tend to be tricky or deceiving in selling but the common ethic of most software developers is openness and it is that openness that makes it easy for us to share challenges experiences and even our faults in public You would agree with me on this if you re a developer Or have you seen any community that shares things that should be secrets in public like software developers Now how is openness makes it hard to sell to developers Psychologically speaking if you re open you have a high tendency to dislike those who are not straightforward isn t it Also developers are very smart people Many of us have learned about human psychology and selling by reading widely and watching documentaries and movies All of this experience plus our encounters with salespeople make us always assume salespeople want to trick us and no human being likes to be tricked For that reason we hate to give sellers our attention Developers are amazingly stubborn in pursuit so we re always strongly opinionated Why do you think we have JavaScript libraries and frameworks that do the same thing basically Why do you think we have DRY WET and YAGNI We tend to be stubborn in our thinking or belief and if you don t have an emotionally and logically convincing product you will struggle to sell to developers Our inherent curiosity makes it very hard to sell software to us and retain us Many of us are okay with wasting our time and night to build or find out how one shining project works In short we like to learn and build our things Are you even a software developer if you don t have unfinished side projects Who doesn t So you can t easily sell software products to us by telling or tricking us to buy them We will rather build our alternative if you make us angry or trick us And if your product is not really convincingly useful curiosity will take us to the next shining things That is the reality Why do you think developers are open It is because if we re not any piece of software will expose us with ease Software exposes marketing gimmicks easily because developers have to go through some experience while using them and developers are highly skeptical of software they have not used practically So developers rarely pay for software without experiencing it judging from experience All this is why using marketing gimmicks without good experience rarely works in selling to developers And it is the responsibility of DevRel to make sure your products work and achieve their purposes They need to work to make sure your users feel the magic in your products the first time they use them If they don t DevRel needs to keep providing information to the stakeholders abstract or create documentation and other forms of content to make the right audience feel the magic in your products The great liability of the engineer compared to men of other professions is that his works are out in the open where all can see them His acts step by step are in hard substance He cannot bury his mistakes in the grave like the doctors He cannot argue them into thin air or blame the judge like the lawyers He cannot like the architects cover his failures with trees and vines He cannot like the politicians screen his shortcomings by blaming his opponents and hoping the people will forget The engineer simply cannot deny he did it If his works do not work he is damned Herbert Hoover American engineer and politicianTalk to me about programming content creation and DevRel on Twitter at Ayobami Ogundiran	2023-05-25 11:37:32
海外TECH	DEV Community	Learn Why we call to use index with PostgreSQL	https://dev.to/nightbird07/learn-why-we-call-to-use-index-with-postgresql-4chn	Learn Why we call to use index with PostgreSQLTo better understand how the cost estimation process works in PostgreSQL it can be helpful to explore practical examples of how it impacts query execution In previous articles we discussed the role of the planner executor sequential scan and runtime scan in query execution To apply these concepts to real world scenarios it s recommended to review the previous article on sequential scans and cost estimation in PostgreSQL What is an indexAn index in PostgreSQL is similar to an index in a book or a set of notes where it provides a way to quickly locate and retrieve specific information Unlike normal tables indexes are stored in a specialized data structure optimized for quick insertion and searching such as B tree GiST or Hash The most common type of index in PostgreSQL is the balanced tree index or B tree which efficiently stores and organizes data in a tree like structure This allows for fast searching and retrieval of data based on the values in the indexed column s Indexes can significantly improve query performance by allowing PostgreSQL to locate and retrieve specific rows more efficiently than scanning the entire table However it s important to note that indexes are not always the optimal solution for all cases In some cases the overhead of maintaining the index can outweigh the performance benefits Therefore it s important to carefully consider the columns to include in an index and monitor the performance of your queries to ensure that the indexes are providing the expected performance improvements Let s write some SQLI have created a PostgreSQL function that generates rows by taking user input for the number of rows and table name With this function I was able to generate over million rows within seconds Next I executed several queries to observe their performance CREATE OR REPLACE FUNCTION generate series n integer name text t text RETURNS void AS BODY DECLARE i integer BEGIN FOR i IN n LOOP EXECUTE INSERT INTO quote ident t VALUES i quote literal name i END LOOP END BODY LANGUAGE plpgsql VOLATILECOST EXPLAIN ANALYZE SELECT id from t where name NAME CREATE INDEX ON t id RESET ALL EXPLAIN ANALYZE SELECT id from t where t id EXPLAIN ANALYZE SELECT name from t where t id The first query took the longest time as it used a sequential scan to filter the rows based on a text column The second and third queries used an index only scan on the primary key column resulting in much faster query performance Resultsthe first one will take the longest query asGather cost rows width actual time rows loops Workers Planned Workers Launched gt Parallel Seq Scan on t cost rows width actual time rows loops Filter name NAME text Rows Removed by Filter Planning Time ms Execution Time msWhen analyzing query performance in PostgreSQL the EXPLAIN ANALYZE command provides valuable insights into the query execution process The output of this command includes information such as the number of worker threads used by the planner the type of scan performed such as sequential or index only the planning time for the query and the execution time for the query While PostgreSQL can use parallel threads to read data from the database and improve performance this should not be relied on as a solution for poorly optimized queries It s important to write clean optimized queries to avoid putting undue load on the CPU The planning time for a query can vary depending on its complexity and optimization but an optimized query should have a planning time that does not significantly impact the total execution time The execution time is the time needed to retrieve the data from the table and is a critical factor in query performance It s recommended to focus on optimizing queries to improve their execution time rather than relying solely on parallelism or increasing hardware resources By optimizing queries and carefully selecting which columns to include in indexes it s possible to achieve significant performance improvements in PostgreSQL Index Only Scan using t id idx on t cost rows width actual time rows loops Index Cond id Heap Fetches Planning Time ms Execution Time ms when index is not really neededthere are two main situations the first is realted to the table itself and the other is realted to the query tablethe table is small the table is updated frequently low selective columns Data the excuted query always fetch pages or large portion of tables then the Seq SCAN is faster	2023-05-25 11:22:12
