Why Every Developer Should Use LeetCode

In the ever-evolving landscape of software development, staying sharp and current with coding skills is not just an advantage; it’s a necessity. LeetCode has emerged as an indispensable tool for developers aiming to hone their problem-solving abilities and technical prowess. Here’s why LeetCode is a must for all developers:

1. Interview Preparation

LeetCode’s extensive collection of coding challenges is tailored to mirror the types of questions asked in technical interviews at leading tech companies. By practicing these problems, developers can gain familiarity with the interview format and question types, boosting their confidence and performance during actual interviews.

2. Mastery of Data Structures and Algorithms

Regular practice on LeetCode helps developers deepen their understanding of data structures and algorithms—a fundamental skill set for any serious coder. This knowledge is not only crucial for interviews but also for writing efficient and scalable code in a professional setting.

3. Keeping Skills Up-to-Date

The tech industry is dynamic, with new languages and frameworks emerging constantly. LeetCode provides resources and tutorials that help developers stay abreast of the latest trends and technologies.

4. Community and Competition

LeetCode has a vibrant community where developers can discuss solutions, share interview experiences, and learn from each other. The competitive aspect of LeetCode also adds a fun and motivating dimension to the learning process.

What is Blind 75?

The Blind 75 is a curated list of 75 LeetCode questions that cover the most common types of problems encountered in coding interviews. It was created by a software engineer during his job search and gained popularity for its effectiveness in preparing candidates for technical interviews. The list is named after the career-centric forum “TeamBlind,” where it was first shared.

The Blind 75 focuses on key areas such as arrays, binary manipulation, dynamic programming, graphs, and more. It’s designed to provide a comprehensive study plan that ensures coverage of the essential topics required for coding interviews.

In conclusion, LeetCode and the Blind 75 list serve as powerful resources for developers at all levels. Whether you’re a beginner looking to break into the industry or an experienced developer aiming to keep your skills sharp, LeetCode is a valuable asset in your professional development arsenal.

Index Clean-Up Scripts

dropping un-used ones, adding missing ones, and fine-tuning the ones I already have. I thought I’d share some of the scripts I’ve been using to accomplish this. Un-Used Indexes Script Declare @dbid int     , @dbName varchar(100);   Select @dbid = DB_ID()     , @dbName = DB_Name();   With partitionCTE (object_id, index_id, row_count, partition_count)  As (     Select [object_id]         , index_id         , Sum([rows]) As 'row_count'         , Count(partition_id) As 'partition_count'     From sys.partitions     Group By [object_id]         , index_id )    Select Object_Name(i.[object_id]) as objectName         , i.name         , Case              When i.is_unique = 1          ...

The SQL Server DBA’s Guide to Teradata

By -
Being a long-time devotee of all things Microsoft SQL Server, I had quite a bit of learning to do to get up to speed on our new Teradata appliance. This guide attempts to distill some of what I have learned. I will primarily focus on what I have found most lacking: examples of how to convert SQL Server T-SQL to Teradata SQL. This guide will use the vendor-supplied sample databases:  SQL Server’s AdventureWorksDW2012 , and the  Teradata’s Express 14.0 Retail database . Also, while this is probably self explanatory, the “mufford” object referenced in the Teradata examples is simply my own personal sandbox. You’ll need to replace any “mufford” reference to whatever your development sandbox may be named. Release History: 2012-08-17 – Added UPDATE examples; reformatted 2012-08-12 – Added date examples 2012-08-08 – Initial Release SELECT Statements Simple SELECT SQL Server: Best practice is to qualify the table schema; qualifying the database is optional unless ...
