Entire twitter feed is filled with why Indians can't build openAI, deepseek etc. Here is my take: The answer to this qsn is simple. India currenly not building this becz its not easy. These are research product. Normal guys can't build it. You require a team and founder of high IQ nerd researchers to build something like that. Some are also thinking, why VCs don't fund deep tech startup? Ans) becz u are not capable. What are your backing? Are u a math olympiad ranker, icpc winner, did u achieve something and have research experience in AI? If u don't have a strong academic background then how can u build something which require pure maths. You are just in the founder mode to play with the VC money. Some are asking, why govt is not doing anything? Ans) Its not govt work to do it. It is purely a private entity job. This qsn is itself a joke. Its always not necessary to build research products for a country to succeed. Normal products which provide high value are also a good way. India has solved UPI, ecommerce, quick commerce and a lot of useful tech challenges. Also, i don't understand this cope behavior, why india is not building this? You are also an Indian, step-up and build it.

Try avoiding SELECT * even on single-column tables One interesting case I ran into with a customer some years ago (2012-2013 I think) A backend API that is stable and runs in single digit millisecond. Until one day users came in to a slow and sluggish user experience. We checked the commits and nothing was obvious, most changes were benign. Just in case we reverted al commits but still the app was slow. Looking at the diagnostics, we noticed API log time taking from 500 ms to up to 2 seconds at times. We know nothing has changed in the backend that would’ve cause the slow down, but started looking at the database queries. SELECT * on a table that has 3 blob fields are being returned to the client, those blob fields has very large documents. It turned out this table had only 2 integer columns, and the API was running a SELECT * to return and use the two fields. But later, the admin added 3 blob fields that are used and populated by another application. While those blob fields were not being returned to the client, the backend API took the hit pulling the extra fields populated by other applications, causing database, network and protocol serialization overhead. So even if you have a single column on your table, just SELECT that column, because the schema can change from underneath you. There are many other reasons to avoid SELECT * of course, but I’ll talk about them in another post. —- if you enjoyed this, check out my fundamentals of database engineering databases.win $11.99 DB-AUG2024-B coupon until Aug 13 Check out the rest of my courses here courses.husseinnasser.com

laapata ladies. [a review thread] -through the lens of cinema. 1/13

Society rewards hyperspecialization, and people just follow the incentives: that’s how we ended up with people who can uncover the secrets of the universe but can’t figure out their own marriage, or people who are respected by all except their own kids, or people who teach others “how to be successful in life” who are actually angry and depressed, or people who can solve the most complex problems but somehow cannot maintain a single long-term meaningful friendship with anyone. You may not become “the best” if you have a well-balanced life, but at least, you will have a shot at sustainable peace of mind, and you may learn how to appreciate the people around you, and enjoy a bit of the rewards that you actually worked hard to earn, instead of living your whole life scared of missing out on the next big opportunity, instead of chasing the wrong goals and noticing, way too late, that they didn’t matter as much as you thought at the time when you were younger, when you thought you knew better, because you were simply surrounded by people who were as blind as you were.

@kiran_kulkarni Wow, interesting!

Excited to unveil my project: Built a RAG for a unified investment portfolio view & advice, overcoming the hassle of collating info from multiple platforms. Fine-tuning in progress, but LLMs promise to transform financial advisory. (Note video is sped up for demo)

If I had to start learning System Design from scratch, I would begin with these 25 articles to get a head start: Thread 🧵

A 🧵on Docker. This is Part 1 - an introductory thread on this topic. Will post more threads on this in future. Read this thread if you don't know anything about docker, containerisation, etc. It is a compulsory topic like Git, Linux for every developer. Thread🧵 (1/14)

Web accessibility: Essential for some, useful to all ✨ Learn how to ensure your website or app is user-friendly for everyone, including those who rely on screen readers. This is especially helpful for developers like us! Post by @imhritik_dj medium.com/helpshift-engi…

Attended my first ever Data Engineering Conference at Banglore. It was such a wonderful experience to meet the greatest minds of the data industry. (Joe Reis and many more) There were some amazing talks and panel discussions. In all a totally great learning experience!

How is an SQL statement executed in the database? The diagram below shows the process. Note that the architectures for different databases are different, the diagram demonstrates some common designs. Step 1 - A SQL statement is sent to the database via a transport layer protocol (e.g.TCP). Step 2 - The SQL statement is sent to the command parser, where it goes through syntactic and semantic analysis, and a query tree is generated afterward. Step 3 - The query tree is sent to the optimizer. The optimizer creates an execution plan. Step 4 - The execution plan is sent to the executor. The executor retrieves data from the execution. Step 5 - Access methods provide the data fetching logic required for execution, retrieving data from the storage engine. Step 6 - Access methods decide whether the SQL statement is read-only. If the query is read-only (SELECT statement), it is passed to the buffer manager for further processing. The buffer manager looks for the data in the cache or data files. Step 7 - If the statement is an UPDATE or INSERT, it is passed to the transaction manager for further processing. Step 8 - During a transaction, the data is in lock mode. This is guaranteed by the lock manager. It also ensures the transaction’s ACID properties. – Subscribe to our weekly newsletter to get a Free System Design PDF (158 pages): bit.ly/3KCnWXq
