My free ebook – A Primer on SQL (2nd Edition)

What it does

An introduction to the basics of SQL. No prior experience with SQL is necessary, but some knowledge of working with computers in general is required. My purpose of writing this was to provide a gentle tutorial on the syntax of SQL, so that the reader is able to recognize the parts of queries they encounter and even be able to write simple SQL statements and queries themselves. The book however is not intended as a reference work or for a full time database administrator since it does not have an exaustive topic coverage. Rahul Batra was first introduced to programming in 1996 in GWBASIC, but he did not seriously foray into it till 2001 when he started learning C++. Along the way, there were…from leanpub.com

  I wrote a technical history book on LispFeb 2026 · berksoft.ca · ▲252

  The book page links to a blog post that explains how I got about it (and has a link to sample content), but the TL&DR is that I could not find a lot of books that were on "our" history _and_ were larded with technical details. So I set about writing one, and some five years later I'm happy to share the result. I think it's one of the few "computer history" books that has tons of code, but correct me if I'm wrong (I wrote this both to tell a story and to learn :-)). My favorite languages are Smalltalk and Lisp, but as an Emacs user, I've been using the latter for much longer and for my…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  JS library to make your website instant▲426

  http://instantclick.io/ It seems the internet architecture won't bring us instant websites anytime soon. So here is a hack. I released this JS library last month (today is version 2.0 release, fixing v1.0's rough edges), it makes use of HTML5's pushState and preloading to make a website instant. It works like this: before clicking on a link, you'll hover over it. And there's a delay of 200-300 ms between these two events. InstantClick uses this delay to preload a page, when you click on a link it will display instantly in most case. (You can test on the website.) That's…

  For a while, I had this idea of redesigning Microsoft employee badges for a modern and neat look. So I spared a few hours this weekend. It’s over a year Microsoft has started to rebrand itself, starting from its logo to a brand new looking OS, from campus shuttles to direction signs on the cam
